£1,250,000,000 8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities

Barclays PLC

We, Barclays PLC (the “Issuer”), are issuing £1,250,000,000 aggregate principal amount of 8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities (the “Securities”). From (and including) the Issue Date (as defined herein) to (but excluding) December 15, 2030 (such date and each fifth (5th) anniversary thereafter being a “Reset Date”), the interest rate on the Securities will be 8.500% per annum. From (and including) each Reset Date to (but excluding) the next following Reset Date, the applicable per annum interest rate will be equal to the sum, as determined by the Calculation Agent (as defined herein), of the applicable Mid-Market Swap Rate (as defined herein) on the relevant Reset Determination Date (as defined herein) and 4.881%, converted to a quarterly rate in accordance with market convention as instructed by the Issuer (rounded to three decimal places, with 0.0005 rounded down). The interest rate following any Reset Date may be less than the initial interest rate and/or the interest rate that applies immediately prior to such Reset Date. Subject to the conditions described herein, interest, if any, will be payable quarterly in arrear on March 15, June 15, September 15 and December 15 of each year (each, an “Interest Payment Date”), commencing on September 15, 2024.

We will apply to the London Stock Exchange plc (the “LSE”) for the Securities to be admitted to trading on the LSE’s International Securities Market (the “ISM”).

The ISM is not a regulated market for the purposes of MiFID II or U.K. MiFIR (each as defined herein). The ISM is a market designated for professional investors. Securities admitted to trading on the ISM are not admitted to the Official List of the U.K. Financial Conduct Authority (the “FCA”). The LSE has not approved or verified the contents of either this prospectus supplement or the accompanying prospectus. Neither this prospectus supplement nor the accompanying prospectus comprises (i) a prospectus or listing particulars for the purposes of Part VI of the Financial Services and Markets Act 2000, as amended (the “FSMA”) or (ii) a prospectus for the purposes of Regulation (EU) 2017/1129 or Regulation (EU) 2017/1129 as it forms part of domestic law of the United Kingdom (“U.K.”) by virtue of the European Union (Withdrawal) Act 2018 (the “Withdrawal Act”).

As described in this prospectus supplement, the terms of the Securities provide that interest on the Securities will be due and payable only at the sole discretion of the Issuer, and the Issuer shall have sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date. As described herein, the terms of the Securities also provide for circumstances under which the Issuer shall be restricted from making an interest payment (in whole or in part) on the Securities on an Interest Payment Date, and the interest payable in respect of any such Interest Payment Date shall be deemed cancelled (in whole or in part) and therefore not due and payable. Interest will only be due and payable on an Interest Payment Date to the extent it is not cancelled or deemed cancelled in accordance with the terms of the Securities and as further described herein. Any interest cancelled or deemed cancelled (in each case, in whole or in part) in accordance with the terms of the Securities and as further described herein shall not be due and shall not accumulate or be payable at any time thereafter, and holders of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation.

The Securities are perpetual and have no fixed maturity or fixed redemption date. As a result of the fact that the Securities are perpetual securities and that interest on the Securities will be due and payable only at our sole discretion and that we may cancel (in whole or in part) any interest payment at any time, we are not required to make any payment of the principal amount of the Securities at any time prior to our winding-up or administration and you may not receive interest on any Interest Payment Date.

The Securities will constitute our direct, unsecured and subordinated obligations, ranking pari passu without any preference among themselves, as described herein. The Securities will be in registered form in minimum denominations of £200,000 and in integral multiples of £1,000 in excess thereof.

As described herein, we may, at our option, redeem the Securities, in whole but not in part, on (i) any day falling in the period commencing on (and including) June 15, 2030 and ending on (and including) the first Reset Date or (ii) any day falling in the period commencing on (and including) the date that is six months before any subsequent Reset Date and ending on (and including) such Reset Date at 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described herein) to (but excluding) the date fixed for redemption.

As described herein, we may also, at our option, redeem the Securities, in whole but not in part, at any time in the event of a change in certain U.K. regulatory capital requirements or upon the occurrence of certain tax events as described herein at 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described herein) to (but excluding) the date fixed for redemption. Additionally, if at any time from the fifth anniversary of the Issue Date (unless otherwise permitted by the PRA (as defined herein)), the outstanding aggregate principal amount of the Securities is 25% or less of the aggregate principal amount of the Securities originally issued, we may redeem all (but not some only) of the outstanding Securities at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described herein) to (but excluding) the date fixed for redemption.

Following the occurrence of such changes in certain U.K. regulatory capital requirements or upon the occurrence of certain tax events, we may also, at our option either substitute all (but not some only) of the Securities for, or vary the terms of the Securities so that they remain or, as appropriate, become, Compliant Securities (as defined herein).

If a Capital Adequacy Trigger Event (as defined herein) occurs, then an Automatic Conversion (as defined herein) will occur on the Conversion Date (as defined herein), at which point all of the Issuer’s obligations under the Securities (other than certain Issuer obligations in connection with the Conversion Shares Offer (as defined herein), if any, which are referred to herein as the CSO Obligations) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares (as defined herein) to the Conversion Shares Depository (as defined herein) (or other relevant recipient as described herein), and under no circumstances shall such released obligations be reinstated. The Conversion Shares shall initially be registered in the name of the Conversion Shares Depository (which shall hold the Conversion Shares on behalf of the holders of the Securities) or the relevant recipient in accordance with the terms of Securities. As more fully described herein, the Issuer may elect, in its sole and absolute discretion, that a Conversion Shares Offer be made by the Conversion Shares Depository to all or some of the then existing shareholders of the Issuer. The realizable value of any Conversion Shares received by a holder of the Securities following an Automatic Conversion may be significantly less than the Conversion Price (as defined herein) of £1.65 initially and holders of the Securities could lose all or part of their investment in the Securities as a result of the Automatic Conversion.

Following an Automatic Conversion, the Securities shall remain in existence until the applicable Cancellation Date (as defined herein) for the sole purpose of evidencing (a) the holder’s right to receive Conversion Shares or Conversion Shares Offer Consideration (as defined herein), as applicable, from the Conversion Shares Depository and (b) the Issuer’s CSO Obligations, if any. All obligations of the Issuer under the Securities (except for the CSO Obligations, if any) shall be irrevocably and automatically released in

consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository (or other relevant recipient as described herein) on the Conversion Date.

IMPORTANT—PRIIPs REGULATION / PROHIBITION OF SALES TO EEA RETAIL INVESTORS. The Securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

IMPORTANT—U.K. PRIIPs REGULATION / PROHIBITION OF SALES TO U.K. RETAIL INVESTORS. The Securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the U.K. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law of the U.K. by virtue of the Withdrawal Act; or (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law of the U.K. by virtue of the Withdrawal Act (“U.K. MiFIR”). Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law of the U.K. by virtue of the Withdrawal Act (the “U.K. PRIIPs Regulation”) for offering or selling the Securities or otherwise making them available to retail investors in the U.K. has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the U.K. may be unlawful under the U.K. PRIIPs Regulation.

In addition to the above, pursuant to the U.K. Financial Conduct Authority Conduct of Business Sourcebook (“COBS”) the Securities are not intended to be offered, sold or otherwise made available and should not be offered, sold or otherwise made available to retail clients (as defined in COBS 3.4) in the U.K.

U.K. MIFIR PRODUCT GOVERNANCE / PROFESSIONAL INVESTORS AND ECPS ONLY TARGET MARKET—Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Securities has led to the conclusion that: (i) the target market for the Securities is only eligible counterparties, as defined in COBS, and professional clients, as defined in U.K. MiFIR; and (ii) all channels for distribution of the Securities to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Securities (a “Distributor”) should take into consideration the manufacturers’ target market assessment; however, a Distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the “U.K. MiFIR Product Governance Rules”) is responsible for undertaking its own target market assessment in respect of the Securities (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

The Issuer is not a bank nor an authorized deposit-taking institution which is authorized under the Banking Act 1959 (Cth) of Australia (the “Australian Banking Act”) nor is it authorized to carry on banking business under the Australian Banking Act. The Securities are not obligations of any government and, in particular, are not guaranteed by the Commonwealth of Australia. The Issuer is not supervised by the Australian Prudential Regulation Authority. Securities that are offered for issue or sale or transferred in, or into, Australia are offered only in circumstances that would not require disclosure to investors under Part 6D.2 or Part 7.9 of the Corporations Act 2001 of Australia and issued and transferred in compliance with the terms of the exemption from compliance with section 66 of the Australian Banking Act that is available to the Issuer. Such Securities are

issued or transferred in, or into, Australia in parcels of not less than A$500,000 in aggregate principal amount. An investment in any Securities issued by the Issuer will not be covered by the depositor protection provisions in section 13A of the Australian Banking Act and will not be covered by the Australian government’s bank deposit guarantee (also commonly referred to as the Financial Claims Scheme) under the Australian Banking Act.

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between us and any holder or beneficial owner of the Securities (or the Trustee on behalf of the holders of the Securities), by acquiring the Securities, each holder and beneficial owner of the Securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power (as defined in the accompanying prospectus) by the Relevant U.K. Resolution Authority (as defined in the accompanying prospectus) that may result in (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, the Securities; (ii) the conversion of all, or a portion of, the principal amount of, or interest on, the Securities into shares or other securities or other obligations of the Issuer or another person (and the issue to, or conferral on, the holder or beneficial owner of the Securities, of such shares, securities or obligations); (iii) the cancellation of the Securities; and/or (iv) the amendment or alteration of the maturity, if any, of the Securities, or the amendment of the amount of interest due on the Securities, or the dates on which interest becomes payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Securities solely to give effect to the exercise by the Relevant U.K. Resolution Authority of such U.K. Bail-in Power. For more information, see “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” below and the section entitled “Description of Contingent Capital Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” in the accompanying prospectus.

By its acquisition of the Securities, each holder and beneficial owner of the Securities acknowledges, accepts, consents and agrees to be bound by and consents to the determinations made by the Issuer, the Independent Adviser, the Trustee, the Principal Paying Agent, the Calculation Agent or other relevant entities, as applicable, to determine the Subsequent Interest Rate in the event the Issuer determines that a Benchmark Event has occurred or that there is a Successor Rate, including as may occur without any prior notice from the Issuer and without the need for the Issuer to obtain any further consent from holders and beneficial owners of the Securities to implement consequential amendments to the Indenture and other agreements or documents relating to the Securities. For more information, see the sections entitled “Description of Contingent Capital Securities—Determination of Subsequent Interest Rate” and “Description of Contingent Capital Securities—Agreement with Respect to the Determination of the Subsequent Interest Rate.”

By its acquisition of the Securities, each holder and beneficial owner of the Securities, to the extent permitted by the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), also waives any and all claims against The Bank of New York Mellon, London Branch, as trustee (the “Trustee”) for, agrees not to initiate a suit against the Trustee in respect of, and agrees that the Trustee shall not be liable for, any action that the Trustee takes, or abstains from taking, in either case in accordance with the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Securities. For more information, see “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” below and the section entitled “Description of Contingent Capital Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” in the accompanying prospectus.

Neither the U.S. Securities and Exchange Commission nor any U.S. state securities commission has approved or disapproved of the Securities or determined that this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The Securities are not deposit liabilities of Barclays PLC and are not covered by the U.K. Financial Services Compensation Scheme or insured by the U.S. Federal Deposit Insurance Corporation, the Canada Deposit Insurance Corporation or any other governmental agency of the United States, the U.K., Canada or any other jurisdiction.

Note:

The Securities will be issued in registered form. The Securities will be represented by one global certificate that will be deposited with a common depositary for Euroclear and/or Clearstream, Luxembourg (each as defined herein), and registered in the name of such common depositary or its nominee. Holders of the Securities will hold beneficial interests in the Securities through Clearstream, Luxembourg and/or Euroclear and their respective direct and indirect participants and such direct and indirect participants will record such beneficial interest on their books.

The underwriters expect to deliver the Securities to purchasers in book-entry form only through the facilities of Clearstream, Luxembourg, and/or Euroclear, on or about May 15, 2024.

S-1

PROHIBITION ON MARKETING AND SALES TO RETAIL INVESTORS

IMPORTANT—PRIIPs REGULATION / PROHIBITION OF SALES TO EEA RETAIL INVESTORS. The Securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; or (ii) a customer within the meaning of the Insurance Distribution Directive, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by the PRIIPs Regulation for offering or selling the Securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

U.K. MIFIR PRODUCT GOVERNANCE / PROFESSIONAL INVESTORS AND ECPS ONLY TARGET MARKET—Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Securities has led to the conclusion that: (i) the target market for the Securities is only eligible counterparties, as defined in COBS, and professional clients, as defined in U.K. MiFIR;

and (ii) all channels for distribution of the Securities to eligible counterparties and professional clients are appropriate. A Distributor should take into consideration the manufacturers’ target market assessment; however, a Distributor subject to the U.K. MiFIR Product Governance Rules is responsible for undertaking its own target market assessment in respect of the Securities (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

IMPORTANT—U.K. PRIIPs REGULATION / PROHIBITION OF SALES TO U.K. RETAIL INVESTORS. The Securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the U.K. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law of the U.K. by virtue of the Withdrawal Act; or (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of U.K. MiFIR. Consequently no key information document required by the U.K. PRIIPs Regulation for offering or selling the Securities or otherwise making them available to retail investors in the U.K. has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the U.K. may be unlawful under the U.K. PRIIPs Regulation.

FORWARD-LOOKING STATEMENTS

This prospectus supplement and certain documents incorporated by reference herein contain certain forward-looking statements within the meaning of Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Section 27A of the U.S. Securities Act of 1933, as amended (the “Securities Act”), with respect to the Group (as defined below). We caution readers that no forward-looking statement is a guarantee of future performance and that actual results or other financial condition or performance measures could differ materially from those contained in the forward-looking statements. Forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements sometimes use words such as “may,” “will,” “seek,” “continue,” “aim,” “anticipate,” “target,” “projected,” “expect,” “estimate,” “intend,” “plan,” “goal,” “believe,” “achieve” or other words of similar meaning. Examples of forward-looking statements include, among others, statements or guidance regarding or relating to the Group’s future financial position, business strategy, income levels, costs, assets and liabilities, impairment charges, provisions, capital leverage and other regulatory ratios, capital distributions (including policy on dividends and share buybacks), return on tangible equity, projected levels of growth in banking and financial markets, industry trends, any commitments and targets (including environmental, social and governance (“ESG”) commitments and targets), plans and objectives for future operations and other statements that are not historical or current facts. By their nature, forward-looking statements involve risk and uncertainty because they relate to future events and circumstances. Forward-looking statements speak only as at the date on which they are made. Forward-looking statements may be affected by a number of factors, including, without limitation: changes in legislation, regulations, governmental and regulatory policies, expectations and actions, voluntary codes of practices and the interpretation thereof, changes in International Financial Reporting Standards (“IFRS”) and other accounting standards, including practices with regard to the interpretation and application thereof and emerging and developing ESG reporting standards; the outcome of current and future legal proceedings and regulatory investigations; the Group’s ability along with governments and other stakeholders to measure, manage and mitigate the impacts of climate change effectively; environmental, social and geopolitical risks and incidents and similar events beyond the Group’s control; the impact of competition in the banking and financial services industry; capital, liquidity, leverage and other regulatory rules and requirements applicable to past, current and future periods; United Kingdom (“U.K.”), United States (“U.S.”), Eurozone and global macroeconomic and business conditions, including inflation; volatility in credit and capital markets; market related risks such as changes in interest rates and foreign exchange rates; reforms to benchmark interest rates and indices; higher or lower asset valuations; changes in credit ratings of any entity within the Group or any securities issued by it; changes in counterparty risk; changes in consumer behavior; the direct and indirect consequences of the conflicts in Ukraine and the Middle East on European and global macroeconomic conditions, political stability and financial markets; political elections; developments in the U.K.’s relationship with the European Union (“E.U.”); the risk of cyber-attacks, information or security breaches, technology failures or operational disruptions and any subsequent impact on the Group’s reputation, business or operations; the Group’s ability to access funding; and the success of acquisitions, disposals and other strategic transactions. A number of these factors are beyond the Group’s control. As a result, the Group’s actual financial position, results, financial and non-financial metrics or performance measures or its ability to meet commitments and targets may differ materially from the statements or guidance set forth in the Group’s forward-looking statements. In setting our targets and outlook for the period 2024-2026, we have made certain assumptions about the macro-economic environment, including, without limitation, inflation, interest and unemployment rates, the different markets and competitive conditions in which we operate, and our ability to grow certain businesses and achieve costs savings and other structural actions. The list above is not exhaustive and there are other factors that may cause our actual results to differ materially from the forward-looking statements contained in this prospectus supplement and the documents incorporated by reference herein. You are also advised to read carefully the risk factors set out in the section entitled “Risk Factors” in this prospectus supplement and in our filings with the U.S. Securities and Exchange Commission (the “SEC”), including, without limitation, in our Annual Report on Form 20-F for the financial year ended December 31, 2023 (File No. 001-09246), filed with the SEC on February 20, 2024 (the “2023 Form 20-F”), which are available on the SEC’s website at http://www.sec.gov for a discussion of certain factors that should be considered when deciding what action to take in relation to the Securities.

Subject to our obligations under the applicable laws and regulations of any relevant jurisdiction (including, without limitation, the U.K. and the U.S.), in relation to disclosure and ongoing information, we undertake no obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

RISK FACTORS

You should carefully consider the risks described below and all of the information contained and incorporated by reference in this document before you decide whether to acquire the Securities.

Investing in the Securities offered under this prospectus supplement involves significant risks. You should reach your own investment decision only after consultation with your own financial, legal and tax advisers (as you deem appropriate) about risks associated with an investment in the Securities and the suitability of investing in the Securities in light of the particular characteristics and terms of the Securities and of your particular financial circumstances. As part of making an investment decision, you should make sure you thoroughly understand the Securities’ terms, such as the provisions governing an Automatic Conversion (including, in particular, the circumstances under which a Capital Adequacy Trigger Event may occur), the agreement by you to be bound by the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority, that interest is due and payable only at the sole discretion of the Issuer, and that there is no scheduled repayment date for the principal of the Securities. You should also carefully consider the risk factors and the other information contained in this prospectus supplement and our 2023 Form 20-F and the other information included and incorporated by reference in this prospectus supplement or the accompanying prospectus before deciding to invest in the Securities and you should evaluate (either alone or with the help of a financial adviser) possible scenarios for economic, interest rate and other factors that may affect an investment in the Securities and your ability to bear the loss of all or a portion of your investment. If any of the risks described herein (including the risks described in the documents incorporated by reference in this prospectus supplement or the accompanying prospectus) materializes, our business, financial condition and results of operations could suffer, the Securities could be subject to Automatic Conversion and/or the U.K. Bail-in Power, and the trading price and liquidity of the Securities and/or our ordinary shares could decline, in which case you could lose some or all of the value of your investment. Terms defined in “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities” have the same meanings in this risk factor section.

Risks Relating to the Securities

The Securities have no scheduled maturity and you do not have the right to cause the Securities to be redeemed or otherwise accelerate the repayment of the principal amount of the Securities except in very limited circumstances.

The Securities are perpetual securities and have no fixed maturity date or fixed redemption date. Accordingly, we are under no obligation to repay all or any part of the principal amount of the Securities, we have no obligation to redeem the Securities at any time and you have no right to call for their redemption or otherwise accelerate the repayment of the principal amount of the Securities (except in the very limited circumstances of automatic acceleration following a Winding-up Event as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Enforcement Events and Remedies” below).

Interest on the Securities will be due and payable only at the sole and absolute discretion of the Issuer, and we may cancel interest payments (in whole or in part) at any time. Cancelled interest shall not be due and shall not accumulate or be payable at any time thereafter and you shall have no rights thereto.

Interest on the Securities will be due and payable only at the sole discretion of the Issuer, and the Issuer shall have sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date. Interest will only be due and payable on an Interest Payment Date to the extent it is not cancelled in accordance with the terms of the Securities. If the Issuer does not make an interest payment on the relevant Interest Payment Date (or if the Issuer elects to make a payment of a portion, but not all, of such interest payment), such non-payment shall evidence the Issuer’s exercise of its discretion to cancel such interest payment (or the portion of such interest payment not paid), and accordingly such interest payment (or the portion thereof not paid) shall not be due and payable.

S-27

Because the Securities are intended to qualify as Additional Tier 1 Capital under U.K. CRD, the Issuer may cancel (in whole or in part) any interest payment on the Securities at its discretion and may pay dividends on its ordinary or preference shares notwithstanding such cancellation. In addition, the Issuer may without restriction use funds that could have been applied to make such cancelled payments to meet its other obligations as they become due.

Cancelled interest shall not be due and shall not accumulate or be payable at any time thereafter, and holders of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation. Furthermore, no cancellation of interest in accordance with the terms of the Indenture shall constitute a default in payment or otherwise under the terms of the Securities. If practicable, we shall provide notice of any cancellation of interest (in whole or in part) to the holders of the Securities through the Clearing Systems. If practicable, we shall endeavor to provide such notice at least five (5) Business Days prior to the relevant Interest Payment Date. However, failure to provide such notice will not have any impact on the effectiveness of, or otherwise invalidate, any such cancellation of interest, or give holders of the Securities any rights as a result of such failure.

In determining any proposed dividend and the appropriate payout ratio, our Board of Directors (the “Board”) will consider, among other things, the expectation of servicing more senior securities. The Securities are senior in rank to ordinary shares. It is the Board’s current intention that, whenever exercising its discretion to declare ordinary share dividends, or its discretion to cancel interest on the Securities, the Board will take into account the relative ranking of these instruments in our capital structure.

However, subject to any applicable law, the Board may at any time depart from the above policy at its sole discretion.

In addition to our right to cancel (in whole or in part) interest payments at any time, the terms of the Securities also restrict us from making interest payments on the Securities in certain circumstances, in which case such interest shall be deemed to have been cancelled. Interest that is deemed cancelled shall not be due and shall not accumulate or be payable at any time thereafter and you shall have no rights thereto.

Subject to terms described below under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation—Restriction on Interest Payments” and the extent permitted therein in respect of partial interest payments, the Issuer shall not make an interest payment on the Securities on any Interest Payment Date (and such interest payment shall therefore be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date) if:

Although the Issuer may, in its sole discretion, elect to make a partial interest payment on the Securities on any Interest Payment Date, it may only do so to the extent that such partial interest payment may be made without breaching the restrictions in paragraphs (a) and (b) above. In addition, the Issuer may elect to make a full or partial interest payment with respect to any Parity Security without making a full or partial interest payment on the Securities on any Interest Payment Date.

The Issuer shall be responsible for determining compliance with this restriction, and neither the Trustee nor any agent shall be required to monitor such compliance or to perform any calculations in connection therewith.

S-28

Any interest deemed cancelled on any relevant Interest Payment Date shall not be due and shall not accumulate or be payable at any time thereafter, and holders of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such deemed cancellation. Furthermore, no cancellation of interest in accordance with the terms of the Securities shall constitute a default in payment or otherwise under the terms of the Securities. If practicable, we shall provide notice of any deemed cancellation of interest (in whole or in part) to the holders of the Securities through the Clearing Systems. If practicable, we shall endeavor to provide such notice at least five (5) Business Days prior to the relevant Interest Payment Date. However, failure to provide such notice will not have any impact on the effectiveness of, or otherwise invalidate, any such cancellation of interest, or give holders of the Securities any rights as a result of such failure.

The Capital Regulations impose capital and regulatory requirements that will restrict the Issuer’s ability to make discretionary distributions in certain circumstances, in which case the Issuer may reduce or cancel interest payments on the Securities. In addition, the PRA has broad powers to impose prudential requirements on the Issuer which may include requiring the Issuer to limit or cancel interest on the Securities.

The capital and regulatory framework to which the Group is subject imposes certain requirements for the Group to hold sufficient levels of capital, including CET1 capital, leverage and additional loss absorbing capacity (including the minimum requirement for own funds and eligible liabilities (“MREL”) and total loss absorbing capacity (“TLAC”)). A failure to comply with such requirements, as the same may be amended from time to time, may result in restrictions on the Issuer’s ability to make discretionary distributions (including on the Securities) in certain circumstances.

In addition, amendments could be made to such framework, to impose general restrictions or prohibitions in relation to discretionary distributions (including in respect of additional tier 1 instruments, such as the Securities) in certain circumstances.

Combined buffer requirement

Pursuant to the Capital Regulations, the Group is subject to capital buffer requirements that are additional to the Pillar 1 “own funds” requirement and are required to be met with CET1 capital. These capital buffers, as currently applicable to the Issuer on a consolidated basis (in respect of the Group), which make up the “combined buffer”, are: (i) the capital conservation buffer, (ii) the institution-specific counter-cyclical capital buffer (“CCyB”) and (iii) the global systemically important institutions (“G-SIIs”) buffer. Please see the section entitled “Risk Review—Supervision and regulation” on pages 290-299 of the 2023 Form 20-F for further information. In addition, CCyBs as determined by other national authorities in relation to the Group’s exposures in their jurisdictions started to apply from 2016 and have continued since. The U.K. CCyB is currently 2% as set by the Financial Policy Committee (“FPC”) of the Bank of England with effect from July 5, 2023. The FPC expects to increase the U.K. CCyB rate when financial vulnerabilities are building up and, in the current context of its overall capital strategy, the FPC judges that the neutral rate for the U.K. CCyB is around 2%, in each case, as stated in its policy statement “The Financial Policy Committee (FPC’s approach to setting the countercyclical capital buffer (CCyB)” published in July 2023.

The PRA capital buffer rules applicable to the Issuer require that firms that fail to meet the “combined buffer” are made subject to restricted discretionary payments (such as payments relating to common equity tier 1, variable remuneration and payments on additional tier 1 instruments) (the “MDA Restrictions”). These types of restrictions have applied in the U.K. since January 1, 2016. In the event of a breach of the “combined buffer,” the MDA Restrictions will be scaled according to the extent of the breach of the “combined buffer” and calculated as a percentage of the profits of the firm earned in each of the past four calendar quarters, net of distributions. Such calculation will result in a “maximum distributable amount” in each relevant period. As an example, the scaling is such that in the bottom quartile of the “combined buffer,” no “discretionary distributions” will be permitted to be paid. As a consequence, in the event of breach of the combined buffer (as applicable at Group level) the Issuer’s discretionary payments will be restricted and the Issuer may exercise its discretion to cancel (in whole or in part) interest payments in respect of the Securities.

S-29

Separately, certain regulatory requirements may restrict the Issuer’s ability to make discretionary distributions in certain circumstances, in which case the Issuer may reduce or cancel interest payments on the Securities. For example, a firm will be deemed not to have met its combined buffer, and may become subject to the MDA Restrictions, where it does not have own funds and eligible liabilities in an amount and quality to meet: (i) its combined buffer, (ii) its 4.5% Pillar 1 CET1 capital requirement and its Pillar 2A CET1 capital requirement, (iii) its 6% Pillar 1 Tier 1 requirement and its Pillar 2A Tier 1 requirement, (iv) its 8% Pillar 1 total capital requirement and its Pillar 2A total capital requirement, and (v) its Pillar 1 and Pillar 2A MREL requirements, including, in the case of G-SIIs (such as the Group), its risk- based ratio and non-risk based ratio. See also the last paragraph under “Interest on the Securities will be due and payable only at the sole and absolute discretion of the Issuer, and we may cancel interest payments (in whole or in part) at any time. Cancelled interest shall not be due and shall not accumulate or be payable at any time thereafter and you shall have no rights thereto” above.

Furthermore, national supervisors may require additional capital to be held by a firm to cover its idiosyncratic risks which the supervisor assesses are not fully captured by the Pillar 1 “own funds” requirement. This additional capital requirement, referred to as “Pillar 2A,” derives from our individual capital guidance, which is a point in time and confidential assessment that, in respect of U.K. firms, is made by the PRA, at least annually, and is expected to vary over time. The Group’s current Pillar 2A requirement is equivalent to 4.6% of Risk Weighted Assets, of which at least 56.25% is required to be met with CET1 capital and no more than 25% may be met with tier 2 capital. In addition, the capital that firms use to meet their minimum requirements (Pillar 1 “own funds” and “Pillar 2A”) cannot be counted towards meeting the “combined buffer,” meaning that the “combined buffer” (which is described above) will effectively be applied above both the Pillar 1 “own funds” and “Pillar 2A” requirements.

The Group’s capital, leverage and/or MREL resources and requirements are, by their nature, calculated by reference to a number of factors, any one of which or combination of which may not be easily observable or capable of calculation by investors. See “—The circumstances surrounding or triggering an Automatic Conversion are unpredictable, and there are a number of factors that could affect the Group’s fully loaded CET1 Ratio,” “—Future regulatory changes to the calculation of CET1 Capital and/or Risk Weighted Assets may negatively affect the Group’s fully loaded CET1 Ratio and thus increase the risk of a Capital Adequacy Trigger Event, which will lead to an Automatic Conversion, as a result of which holders of the Securities could lose all or part of the value of their investment in the Securities” herein for examples of the type of factors that can affect the Group’s capital, leverage and/or MREL resources and requirements and how they are determined. Therefore, you may not be able to predict accurately the proximity of the risk of discretionary payments on the Securities being prohibited from time to time as a result of the operation of the MDA Restrictions and/or the exercise by the PRA of its broad powers to impose prudential requirements on the Issuer. Accordingly, the trading behavior of the Securities is not necessarily expected to follow the trading behavior of other types of securities. Any indication that a breach of the combined buffer or an exercise by the PRA of its broad powers to impose prudential requirements may occur can be expected to have a material adverse effect on the trading price of the Securities.

PRA power to limit or cancel interest

There are additional tools that the PRA and other relevant authorities in the U.K. have, or are expected to have, available to them to require U.K. firms to hold additional capital to address micro-prudential or macro-prudential risks as assessed by the relevant authorities in the U.K. These include, the “PRA buffer” (replacing the capital planning buffer), which may be assessed by the PRA to cover risks over a forward-looking planning horizon, including with regard to firm-specific stresses or management and governance weaknesses. If the PRA buffer is imposed on a specific firm, it must be met separately to the “combined buffer”, and must be met fully with CET1 capital. Failure by the Issuer to meet its PRA buffer (so long as one is imposed), could result in the PRA requiring the Issuer to prepare a capital restoration plan. Such capital restoration plan may impose restrictions on discretionary payments, which may result in the cancellation (in whole or in part) of interest

S-30

payments in respect of the Securities. In addition, “sectoral capital requirements” could be imposed as a macroprudential tool to increase firms’ capital requirements as a result of exposure to specific sectors (for example, via the revised systemic risk buffer).

More generally, the PRA has a broad power under sections 55M and 192C of the FSMA, to impose requirements on the Issuer to strengthen its capital position, the effect of which could be to restrict or prohibit payments of interest on the Securities. If the PRA imposes such a requirement, the Issuer will exercise its discretion to cancel (in whole or in part, as required by the PRA) interest payments in respect of the Securities.

Any further changes to the rules to include more onerous requirements, and/or any decrease in the Group’s capital, leverage and/or MREL resources, and/or increase in such requirements applicable to the Group, may increase the risk of (i) the Issuer breaching its combined buffer and being bound by MDA Restrictions and/or (ii) the PRA imposing requirements on the Issuer under sections 55M and 192C of the FSMA, each of which may, in turn, increase the risk of the Issuer exercising its discretion to cancel interest payments in respect of the Securities. Moreover, a decline or perceived decline in the Group’s capital, leverage and/or MREL resources towards a level at which a breach of the combined buffer requirement or an exercise of the PRA’s powers under section 55M and 192C of the FSMA may occur, may significantly affect the trading price of the Securities.

As a holding company, the level of the Issuer’s Distributable Items and its available funding may be affected by a number of factors. Insufficient Distributable Items or funding may restrict the Issuer’s ability to make interest payments on the Securities.

As a holding company, the level of the Issuer’s Distributable Items is affected by a number of factors, principally its ability to receive funds, directly or indirectly, from its operating subsidiaries in a manner which creates Distributable Items for the Issuer. The Issuer is also reliant on the receipt of distributions from its subsidiaries for funding the Issuer’s payment obligations. Consequently, the level of the Issuer’s Distributable Items and available funding, and therefore its ability to make interest payments on the Securities, are a function of its existing Distributable Items, future Group profitability, the ability of the Issuer’s operating subsidiaries to distribute or dividend profits up the Group structure to the Issuer and other factors such as the amount and availability of such profits and how they are calculated in accordance with accounting rules including the valuation of investment in subsidiaries. In addition, the Issuer’s Distributable Items available for making payments to holders may also be adversely affected by the servicing of other instruments issued by the Issuer or by Group subsidiaries.

The level of the Issuer’s Distributable Items may be further affected by changes to regulation or the requirements and expectations of applicable regulatory authorities. For example, the U.K. implemented U.K. ring-fencing requirements which became effective as of January 2019, while in the United States, an intermediate holding company (“U.S. IHC”) was created to comply with section 165 of the Dodd-Frank Act (each as discussed in the section entitled “Risk Review—Supervision and regulation” on pages 290-299 of the 2023 Form 20-F). Any such changes or similar local capital or ring-fencing requirements in other jurisdictions, could adversely affect the Issuer’s Distributable Items in the future.

In addition, the ability of the Group’s subsidiaries to make distributions and the Issuer’s ability to receive distributions and other payments from its investments in other entities is subject to applicable local laws and other restrictions, including such subsidiaries’ respective regulatory, capital and leverage requirements, statutory reserves, financial and operating performance and applicable tax laws. For example, BBPLC is an institution regulated by the PRA and subject to the U.K. CRD regime, including capital and combined buffer requirements such as those described for the Group (see “—The Capital Regulations impose capital and regulatory requirements that will restrict the Issuer’s ability to make discretionary distributions in certain circumstances, in which case the Issuer may reduce or cancel interest payments on the Securities. In addition, the PRA has broad powers to impose prudential requirements on the Issuer which may include requiring the Issuer to limit or cancel interest on the Securities” herein). In addition, BBUKPLC and the U.S. IHC each have individual capital and

S-31

buffer requirements and similar requirements may apply to other subsidiaries over time. The continuing progress in the implementation of international principles and EU and domestic rules and regulations (including such rules and regulations in the U.K. or in other jurisdictions in which the Group operates) around additional loss absorbing capacity (such as TLAC and MREL) are expected to increase current requirements. Such rules and regulations could limit the payment of dividends, distributions and other payments to the Issuer by its subsidiaries, which could restrict the Issuer’s available funding for meeting its obligations or funding other operations and may also restrict the Issuer’s ability to maintain or increase its Distributable Items. These factors could, in turn, restrict the Issuer’s ability to make interest payments on the Securities.

Further, the Issuer’s Distributable Items and its available funding, and therefore its ability to make interest payments, may be adversely affected by the performance of the Group’s business in general, factors affecting its financial position (including capital and leverage), the economic environment in which the Group operates and other factors outside of the Issuer’s control. In addition, adjustments to earnings, as determined by the Board, may fluctuate significantly and may materially adversely affect Distributable Items. The Issuer shall not make an interest payment on the Securities on any Interest Payment Date (and such interest payment shall therefore be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date) if the level of Distributable Items is insufficient to fund that payment, as discussed in the risk factor “—In addition to our right to cancel (in whole or in part) interest payments at any time, the terms of the Securities also restrict us from making interest payments on the Securities in certain circumstances, in which case such interest shall be deemed to have been cancelled. Interest that is deemed cancelled shall not be due and shall not accumulate or be payable at any time thereafter and you shall have no rights thereto” above. In addition, if the Issuer’s ability to receive distributions from its subsidiaries is restricted and alternative sources of funding are not available, the Issuer may exercise its discretion to cancel interest payments in respect of the Securities (see “—Interest on the Securities will be due and payable only at the sole and absolute discretion of the Issuer, and we may cancel interest payments (in whole or in part) at any time. Cancelled interest shall not be due and shall not accumulate or be payable at any time thereafter and you shall have no rights thereto”).

The Issuer is a holding company, which means that its right to participate in the assets of any of its subsidiaries (including those of BBPLC, BBUKPLC, Barclays Execution Services Limited or any other present or future subsidiary) upon the liquidation of such subsidiaries and the extent to which the Issuer suffers losses if it or any of its subsidiaries are subject to bank resolution proceedings, may depend, amongst other things, upon the degree to which the Issuer’s loans to, and investments in, such subsidiaries are subordinated.

The Issuer is a holding company that currently has no significant assets other than its loans to, and investments in, Group subsidiaries such as BBPLC, BBUKPLC, Barclays Execution Services Limited and any other present or future subsidiary, which means that if any such subsidiary is liquidated, the Issuer’s right to participate in the assets of such subsidiary will depend upon the ranking of the Issuer’s claims against such subsidiary according to the ordinary hierarchy of claims in insolvency. So, for example, insofar as the Issuer is a holder of ordinary shares in a Group subsidiary, the Issuer’s recovery in the liquidation of such subsidiary will be subject to the prior claims of such subsidiary’s third party creditors and preference shareholders (if any). To the extent the Issuer holds other claims against any Group subsidiary that are recognized to rank pari passu with any third party creditors’ or preference shareholders’ claims, such claims of the Issuer should in liquidation be treated pari passu with those third party claims.

As well as the risk of losses in the event of a Group subsidiary’s insolvency, the Issuer may suffer losses if any of its loans to, or investments in, such subsidiary are subject to write-down and conversion by statutory power or regulatory direction or if the subsidiary is otherwise subject to resolution proceedings. In particular, the U.K. Banking Act 2009, as amended (the “Banking Act”) specifies that the resolution powers should be applied in a manner such that losses are transferred to shareholders and creditors in an order which reflects the hierarchy of issued instruments under the relevant Capital Regulations and which otherwise respects the hierarchy of claims in an ordinary insolvency. In general terms, the more junior the investments in, and loans made to, any

S-32

Group subsidiary are, relative to third party investors, the greater the losses likely to be suffered by the Issuer in the event that any Group subsidiary enters into resolution proceedings or is subject to write-down or conversion of its capital instruments or other liabilities. See “—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities” below. The Issuer has in the past made, and may continue to make, loans to, and investments in, BBPLC, BBUKPLC and other Group subsidiaries, with the proceeds received from the Issuer’s issuance of debt instruments. Such loans to, and investments made by, the Issuer in such subsidiary will generally be subordinated to depositors and other unsubordinated creditors and may be subordinated further to meet regulatory requirements and furthermore may contain mechanisms that, upon the occurrence of a trigger related to the prudential or financial condition of the Group or such subsidiary or upon regulatory direction would result in a write-down or conversion into equity of such loans and investments.

The Issuer retains its absolute discretion to restructure such loans to, and any other investments in, any of its Group subsidiaries, including BBPLC and BBUKPLC, at any time and for any purpose including, without limitation, in order to provide different amounts or types of capital or funding to such subsidiary. A restructuring of a loan or investment made by the Issuer in a Group subsidiary could include changes to any or all features of such loan or investment, including its legal or regulatory form, how it would rank in the event of resolution and/ or insolvency proceedings in relation to the Group subsidiary, and the inclusion of a mechanism that provides for a write-down and/or conversion into equity upon specified triggers or regulatory direction. Any restructuring of the Issuer’s loans to, and investments in, any of the Group subsidiaries may be implemented by the Issuer without prior notification to, or consent of, the holders of the Securities.

Furthermore, as a result of the structural subordination of the Securities issued by the Issuer described above, if any Group subsidiary were to be wound up, liquidated or dissolved, (i) the holders of the Securities would have no right to proceed against the assets of such subsidiary, and (ii) the liquidator of such subsidiary would first apply the assets of such subsidiary to settle the claims of the creditors (and holders of preference shares or other tier 1 capital instruments ranking ahead of any such entity’s ordinary shares) of such subsidiary (such creditors and holders of preference shares may include the Issuer) ranking ahead of the holders of ordinary shares of such subsidiary. Similarly, if any of the Group subsidiaries were subject to resolution proceedings (i) the holders of the Securities would have no direct recourse against such subsidiary, and (ii) holders of the Securities themselves may also be exposed to losses pursuant to the exercise by the Relevant U.K. Resolution Authority of the resolution powers conferred by the SRR (as defined below) or the mandatory write-down and conversion power—see “Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities” below. For a description of the relevant underlying regulatory background, see the section entitled “Risk Review—Supervision and regulation” on pages 290-299 of the 2023 Form 20-F.

The Securities may be traded with accrued interest, but under certain circumstances described above, such interest may be cancelled and not paid on the relevant Interest Payment Date.

The Securities may trade, and/or the prices for the Securities may appear, on the ISM and in other trading systems with accrued interest. If this occurs, purchasers of Securities in the secondary market will pay a price that includes such accrued interest upon purchase of the Securities. However, if a payment of interest on any Interest Payment Date is cancelled or deemed cancelled (in each case, in whole or in part) as described herein and thus is not due and payable, purchasers of such Securities will not be entitled to that interest payment (or if the Issuer elects to make a payment of a portion, but not all, of such interest payment, the portion of such interest payment not paid) on the relevant Interest Payment Date.

S-33

The interest rate on the Securities will reset on each Reset Date, which can be expected to affect the interest payment on an investment in the Securities and could affect the market value of the Securities.

The interest rate on the Securities will initially be 8.500% per annum. However, the interest rate will be reset on each Reset Date such that from (and including) each Reset Date, the applicable per annum interest rate will be equal to the sum, as determined by the Calculation Agent, of the applicable Mid-Market Swap Rate on the relevant Reset Determination Date immediately preceding the relevant Reset Date and the Margin, converted to a quarterly rate in accordance with market convention as instructed by the Issuer (rounded to three decimal places, with 0.0005 rounded down). The interest rate following any Reset Date may be less than the initial interest rate and/or the interest rate that applies immediately prior to such Reset Date, which would result in the amount of any interest under the Securities being lower than the interest prior to such Reset Date and so could affect the amount of any interest payments under the Securities and so the market value of the Securities.

The Securities may be subject to an Automatic Conversion and upon the occurrence of such an event you could lose all or part of the value of your investment in the Securities.

A Capital Adequacy Trigger Event will occur if at any time the Group’s fully loaded CET1 Ratio has fallen below 7.00%. Whether a Capital Adequacy Trigger Event has occurred at any time shall be determined by the Issuer and such determination shall be binding on the Trustee and the holders of the Securities. Upon the occurrence of a Capital Adequacy Trigger Event, an Automatic Conversion will occur on the Conversion Date, at which point all of the Issuer’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository to be held on your behalf (or to the relevant recipient in accordance with terms of the Securities), and under no circumstances shall such released obligations be reinstated. As a result, you could lose all or part of the value of your investment in the Securities, as, following an Automatic Conversion, you will receive only (i) the Conversion Shares (if the Issuer does not elect that a Conversion Shares Offer be made) or (ii) the Conversion Shares Offer Consideration, which shall comprise Conversion Shares and/or cash depending on the results of the Conversion Shares Offer (if the Issuer elects that a Conversion Shares Offer be made). In addition, the realizable value of any Conversion Shares received could be substantially lower than that implied by the price paid for the Securities at the time of their purchase and upon an Automatic Conversion, holders will no longer have a debt claim in relation to the Securities. See “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Automatic Conversion Upon Capital Adequacy Trigger Event” for more information. See also “—Holders of the Securities may receive Conversion Shares Offer Consideration instead of Conversion Shares upon a Capital Adequacy Trigger Event and would not know the composition of any Conversion Shares Offer Consideration until the end of the Conversion Shares Offer Period,” “—As the Conversion Price is fixed at the time of issue of the Securities, holders will bear the risk of fluctuations in the market price of the Conversion Shares and the risk of depreciation of sterling against the U.S. dollar” and “Our obligations under the Securities will be unsecured and subordinated, and the rights of the holders of Conversion Shares will be further subordinated.”

Furthermore, upon the occurrence of an Automatic Conversion, the holders will not be entitled to any compensation in the event of any improvement in the Group’s fully loaded CET1 Ratio after the Conversion Date.

For more information, see “—The circumstances surrounding or triggering an Automatic Conversion are unpredictable, and there are a number of factors that could affect the Group’s fully loaded CET1 Ratio,” “—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities” and “—Future regulatory changes to the calculation of CET1 Capital and/or Risk Weighted Assets may negatively affect the Group’s fully loaded CET1 Ratio and thus increase the risk of a Capital Adequacy Trigger Event, which will lead to an Automatic Conversion, as a result of which holders of the Securities could lose all or part of the value of their investment in the Securities.”

S-34

As the Conversion Price is fixed at the time of issue of the Securities, holders will bear the risk of fluctuations in the market price of the Conversion Shares and the risk of depreciation of sterling against the U.S. dollar.

Because a Capital Adequacy Trigger Event will only occur at a time when the Group’s fully loaded CET1 Ratio has deteriorated significantly, a Capital Adequacy Trigger Event may be accompanied by a deterioration in the market price of the Issuer’s ordinary shares, which may be expected to continue after the occurrence of the Capital Adequacy Trigger Event. Therefore, following a Capital Adequacy Trigger Event, the realizable value of the Conversion Shares may be below the Conversion Price. The Conversion Price is fixed at the time of issue of the Securities at £1.65 per Conversion Share, and is subject to certain anti-dilution adjustments, as described under “—Holders of the Securities do not have anti-dilution protection in all circumstances” below. As a result, the Conversion Price may not reflect the market price of ordinary shares of the Issuer, which could be significantly lower than the Conversion Price.

Moreover, as our ordinary shares are denominated and trade in sterling, the U.S. dollar value of our ordinary shares may fluctuate depending on the exchange rate between sterling and the U.S. dollar. For example, if sterling depreciates relative to the U.S. dollar, the U.S. dollar value of our ordinary shares will decrease. Depreciation of sterling against the U.S. dollar may result in the U.S. dollar value of any Conversion Shares received by a holder of the Securities following an Automatic Conversion being significantly less than the U.S. dollar equivalent of the Conversion Price on the date of this prospectus supplement.

In addition, there may be a delay in a holder receiving its Conversion Shares following a Capital Adequacy Trigger Event (in particular if we elect that a Conversion Shares Offer be conducted, as the Conversion Shares Offer Period may last up to forty (40) Business Days after the delivery of the Conversion Shares Offer Notice), during which time the market price of the ordinary shares of the Issuer or the exchange rate of sterling against the U.S. dollar may further decline. As a result, the realizable value in U.S. dollars of the Conversion Shares received upon a Capital Adequacy Trigger Event could be substantially lower than that implied by the sterling price paid for the Securities at the time of their purchase.

No interest or other compensation is payable in the event of a loss by a holder of Securities due to foreign currency conversions.

Issuance of the Conversion Shares to the Conversion Shares Depository shall constitute a complete, irrevocable and automatic release of all of the Issuer’s obligations in respect of the Securities (other than the CSO Obligations, if any).

Upon an Automatic Conversion, the Issuer shall issue the Conversion Shares to the Conversion Shares Depository, which will hold the Conversion Shares on behalf of the holders of the Securities. Issuance of the Conversion Shares to the Conversion Shares Depository shall constitute a complete, irrevocable and automatic release of all of the Issuer’s obligations in respect of the Securities (other than the CSO Obligations, if any). Provided that the Issuer issues the Conversion Shares to the Conversion Shares Depository in accordance with the terms of the Securities as described herein, with effect from the Conversion Date, holders of the Securities shall have recourse only to the Conversion Shares Depository for the delivery to them of Conversion Shares or, if the Issuer elects that a Conversion Shares Offer be made as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares Offer” below, of any Conversion Shares Offer Consideration to which such holders are entitled as described herein.

In addition, we have not as at the Issue Date appointed a Conversion Shares Depository and we may not be able to appoint a Conversion Shares Depository if an Automatic Conversion occurs. In such a scenario, we would give notice to the holders of the Securities through the Clearing Systems or the Trustee or otherwise, as practicable, of any alternative arrangements in connection with the issuance and/or delivery of the Conversion Shares and such arrangements may be disadvantageous to, and more restrictive on, the holders of the Securities.

S-35

For example, such arrangements may involve holders of the Securities having to wait longer to receive their Conversion Shares than would be the case under the arrangements expected to be entered into with a Conversion Shares Depository. Under these circumstances, the Issuer’s issuance of the Conversion Shares to the relevant recipient in accordance with these alternative arrangements shall constitute a complete, irrevocable and automatic release of all of the Issuer’s obligations in respect of the Securities (other than the CSO Obligations, if any).

Holders of the Securities may receive Conversion Shares Offer Consideration instead of Conversion Shares upon a Capital Adequacy Trigger Event and would not know the composition of any Conversion Shares Offer Consideration until the end of the Conversion Shares Offer Period.

Holders of the Securities may not ultimately receive Conversion Shares upon a Capital Adequacy Trigger Event because the Issuer may elect, in its sole and absolute discretion, that a Conversion Shares Offer be conducted by the Conversion Shares Depository.

The Conversion Shares Offer may be conducted at the election of the Issuer, in its sole and absolute discretion, on the terms set out in “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares Offer.” The Issuer currently expects that in determining whether or not a Conversion Shares Offer shall be conducted and, if one is to be conducted, how and to whom such Conversion Shares Offer shall be made, the directors of the Issuer would, in accordance with their duties, have regard to a variety of matters, including, without limitation, the interests of the Issuer’s shareholders, taken as a whole, and the potential impact of a Conversion Shares Offer on the Issuer’s financial stability.

If the Issuer elects, in its sole and absolute discretion, that a Conversion Shares Offer be conducted by the Conversion Shares Depository and all of the Conversion Shares are sold in the Conversion Shares Offer, holders of the Securities shall be entitled to receive, in respect of each Security, the pro rata share of the cash proceeds in sterling from the sale of the Conversion Shares attributable to such Security. If some but not all of the Conversion Shares are sold in the Conversion Shares Offer, holders of the Securities shall be entitled to receive, in respect of each Security, (a) the pro rata share of the cash proceeds in sterling from the sale of the Conversion Shares attributable to such Security together with (b) the pro rata share of the Conversion Shares not sold pursuant to the Conversion Shares Offer attributable to such Security rounded down to the nearest whole number of Conversion Shares. In each case, the cash component of any Conversion Shares Offer Consideration shall be subject to deduction of an amount equal to the pro rata share of any stamp duty, stamp duty reserve tax, or any other capital, issue, transfer, registration, financial transaction or documentary tax that may arise or be paid as a consequence of the transfer of Conversion Shares to the Conversion Shares Depository as a consequence of the Conversion Shares Offer.

No interest or other compensation is payable in respect of the period elapsed from the Conversion Date to the date of delivery of cash sums or Conversion Shares in the circumstances described above.

Furthermore, the Issuer or the Conversion Shares Depository will provide notice of the results of any Conversion Shares Offer only at the end of the Conversion Shares Offer Period. Accordingly, holders of the Securities would not know the composition of the Conversion Shares Offer Consideration to which they may be entitled until the end of the Conversion Shares Offer Period.

Following an Automatic Conversion, the Securities will remain in existence until the applicable Cancellation Date for the sole purpose of evidencing the holder’s right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository and the Issuer’s CSO Obligations, if any, and the rights of the holders of the Securities will be limited accordingly.

Following an Automatic Conversion, the Securities will remain in existence until the applicable Cancellation Date for the sole purpose of evidencing (a) the holder’s right to receive Conversion Shares or

S-36

Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository and (b) the Issuer’s CSO Obligations, if any. All obligations of the Issuer under the Securities (except for the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date, and under no circumstances shall such released obligations be reinstated. The Securities shall be cancelled on the applicable Cancellation Date.

Although we currently expect that beneficial interests in the Securities will be transferable between the Conversion Date and the Suspension Date, there is no guarantee that an active trading market will exist for the Securities following the Automatic Conversion. Accordingly, the price received for the sale of any beneficial interest under a Security during this period may not reflect the market price of such Security or the Conversion Shares. Furthermore, transfers of beneficial interests in the Securities may be restricted following the Conversion Date, for example if the clearance and settlement of transactions in the Securities is suspended by any of the Clearing Systems at an earlier time than currently expected. In such a situation it may not be possible to transfer beneficial interests in the Securities and trading in the Securities may cease.

We expect that, on the Suspension Date, each of the Clearing Systems will block all positions relating to the Securities held in such Clearing System, which will suspend all clearance and settlement of transactions in the Securities through such Clearing System. As a result, holders of the Securities will not be able to settle the transfer of any Securities through such Clearing System following the Suspension Date with respect to such Clearing System, and any sale or other transfer of the Securities that such holder may have initiated prior to the Suspension Date with respect to such Clearing System that is scheduled to match or settle after the Suspension Date will be rejected by such Clearing System and will not be matched or settled through such Clearing System.

The Securities will cease to be admitted to trading on the ISM after the Suspension Date, subject to receipt by the ISM of any notice by the Issuer required under the ISM’s rules and operating procedures.

Moreover, although the holders of the Securities will become beneficial owners of the Conversion Shares upon the issuance of such Conversion Shares to the Conversion Shares Depository and the Conversion Shares will be registered in the name of the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities), no holder of the Securities will be able to sell or otherwise transfer any Conversion Shares until such time as they are finally delivered to such holder and registered in their name.

Holders of the Securities will have to submit a Conversion Shares Settlement Notice in order to receive delivery of the Conversion Shares or the Conversion Share component, if any, of any Conversion Shares Offer Consideration, as applicable.

In order to obtain delivery of the relevant Conversion Shares or the Conversion Share component, if any, of any Conversion Shares Offer Consideration, as applicable, a holder of the Securities must deliver a Conversion Shares Settlement Notice (and the relevant Securities, if applicable) to the Conversion Shares Depository. The Conversion Shares Settlement Notice must contain certain information, including the holder’s CREST account details. Accordingly, holders of Securities (or their nominee, custodian or other representative) will have to have an account with CREST in order to receive the Conversion Shares or Conversion Share component, if any, of any Conversion Shares Offer Consideration, as applicable. If a holder of the Securities fails to properly complete and deliver a Conversion Shares Settlement Notice on or before the Notice Cut-off Date, the Conversion Shares Depository shall continue to hold the relevant Conversion Shares or Conversion Share component, if any, of any Conversion Shares Offer Consideration until a Conversion Shares Settlement Notice (and the relevant Securities, if applicable) is or are so delivered. However, the relevant Securities shall be cancelled on the Final Cancellation Date and any holder of Securities delivering a Conversion Shares Settlement Notice after the Notice Cut-off Date will have to provide evidence of its entitlement to the relevant Conversion Shares (or the relevant Conversion Shares component, if any, of any Conversion Shares Offer Consideration) satisfactory to the Conversion Shares Depository in its sole and absolute discretion in order to receive delivery of such Conversion Shares (or

S-37

Conversion Share component of any Conversion Shares Offer Consideration, as applicable). The Issuer shall have no liability to any holder of the Securities for any loss resulting from such holder not receiving any Conversion Shares (or Conversion Share component of any Conversion Shares Offer Consideration, as applicable) or from any delay in the receipt thereof, in each case as a result of such holder failing to duly submit a Conversion Shares Settlement Notice and the relevant Securities, if applicable, on a timely basis or at all.

Holders of the Securities do not have anti-dilution protection in all circumstances.

The number of Conversion Shares to be issued to the Conversion Shares Depository upon an Automatic Conversion will be the aggregate principal amount of the Securities outstanding immediately prior to the Automatic Conversion on the Conversion Date divided by the Conversion Price (rounded down to the nearest whole number of Conversion Shares). The Conversion Price will be adjusted if there is a consolidation, reclassification or subdivision of the Issuer’s ordinary shares, an issuance of ordinary shares in certain circumstances by way of capitalization of profits or reserves, a rights issue, an Extraordinary Dividend or a Qualifying Takeover Event (but only in the situations and only to the extent provided in “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Anti-Dilution”). There is no requirement that there should be an adjustment for every corporate or other event that may affect the market price of the Conversion Shares. In particular, there will be no adjustment to the Conversion Price if a Takeover Event occurs that is not a Qualifying Takeover Event (because the Acquirer is not an Approved Entity or the New Conversion Condition is not satisfied). Furthermore, the adjustment events that are included are less extensive than those often included in the terms of convertible securities. Accordingly, the occurrence of events in respect of which no adjustment to the Conversion Price is made may adversely affect the value of the Securities.

If a Takeover Event occurs, the Securities may be convertible into shares of an entity other than the Issuer or into unlisted shares.

If a Takeover Event is a Qualifying Takeover Event, then following an Automatic Conversion the Securities shall become convertible or exchangeable into the Approved Entity Shares of the Acquirer at the New Conversion Price as more fully described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Anti-Dilution—Qualifying Takeover Event” below. There can be no assurance as to the nature of any such Acquirer, or of the risks associated with becoming an actual or potential shareholder in such Acquirer and, accordingly, a Qualifying Takeover Event may have an adverse effect on the value of the Securities.

If the Issuer’s ordinary shares become delisted following a Takeover Event which is not a Qualifying Takeover Event or otherwise, there shall be no automatic adjustment to the terms of the Securities and the Securities will remain convertible into unlisted ordinary shares upon an Automatic Conversion. Unlisted shares may be more illiquid than listed shares and may have little or no resale value. In addition, if a Takeover Event is not a Qualifying Takeover Event because the Acquirer is a Governmental Entity, there can be no assurance as to whether the Securities would be convertible into, or exchangeable for, any securities or other instruments of the Acquirer or any other person or entity. Accordingly, a Takeover Event that is not a Qualifying Takeover Event is likely to have an adverse effect on holders of the Securities or the value of the Securities.

In addition, the Issuer has considerable discretion in determining whether a Qualifying Takeover Event has occurred. A Qualifying Takeover Event requires the New Conversion Condition to be satisfied. For the New Conversion Condition to be satisfied, among other requirements, the Issuer must determine, in its sole and absolute discretion, that the arrangements to deliver Approved Entity Shares following an Automatic Conversion are in place and that such arrangements would be in the best interest of the Issuer and its shareholders taken as a whole having regard to the interests of its stakeholders (including, but not limited to, the holders of the Securities) and are consistent with applicable law and regulation (including, but not limited to, the guidance of any applicable regulatory body). Therefore, the Issuer may consider factors other than the interests of holders of the Securities in determining whether the New Conversion Condition is satisfied.

S-38

Further, a Takeover Event shall occur only where the right to cast more than 50% of the votes which may ordinarily be cast on a poll at a general meeting of the Issuer has or will become unconditionally vested in an Acquirer (together with any associate). There can be no assurance that the acquisition by an Acquirer of the right to cast 50% or less of the votes which may ordinarily be cast on a poll at a general meeting of the Issuer will not have an adverse effect on the value of the Securities.

Holders of the Securities may be subject to disclosure obligations, take-over requirements and/or may need approval from the Issuer’s regulator under certain circumstances.

As the holders of the Securities may receive Conversion Shares if a Capital Adequacy Trigger Event occurs, an investment in the Securities may result in holders having to comply with certain disclosure, take-over and/or regulatory approval requirements pursuant to applicable laws and regulations following an Automatic Conversion. For example, pursuant to Chapter 5 of the Disclosure Rules and Transparency Rules Sourcebook of the FCA Handbook, the Issuer (and the FCA) must be notified by a person when the percentage of voting rights in the Issuer controlled by that person (together with its concert parties), by virtue of direct or indirect holdings of shares aggregated with direct or indirect holdings of certain financial instruments, reaches, exceeds or falls below 3% and every percentage point thereafter.

Furthermore, as Conversion Shares represent voting securities of a parent undertaking of a number of regulated group entities, under the laws of the U.K., the United States and other jurisdictions, ownership of the Securities themselves (or the Conversion Shares) above certain levels may require the holder of the voting securities to obtain regulatory approval or subject the holder to additional regulation.

Non-compliance with such disclosure and/or approval requirements may lead to the incurrence of substantial fines or other criminal and/or civil penalties and/or suspension of voting rights associated with the Conversion Shares. Accordingly, each potential investor should consult its legal advisers as to the terms of the Securities, in respect of its existing shareholding and the level of holding it would have if it receives Conversion Shares following a Capital Adequacy Trigger Event.

Holders of the Securities will bear the risk of changes in the Group’s fully loaded CET1 Ratio.

The market price of the Securities is expected to be affected by changes in the Group’s fully loaded CET1 Ratio. Changes in the Group’s fully loaded CET1 Ratio may be caused by changes in the amount of CET1 Capital and/ or Risk Weighted Assets as well as changes to their respective definition and/or interpretation by the Issuer under the Capital Regulations. Each of the Group’s CET1 Capital and/or Risk Weighted Assets shall be determined by the Issuer on a fully loaded and consolidated basis and such determination shall be binding on the Trustee and the holders. See “—The circumstances surrounding or triggering an Automatic Conversion are unpredictable, and there are a number of factors that could affect the Group’s fully loaded CET1 Ratio” and “Future regulatory changes to the calculation of CET1 Capital and/or Risk Weighted Assets may negatively affect the Group’s fully loaded CET1 Ratio and thus increase the risk of a Capital Adequacy Trigger Event, which will lead to an Automatic Conversion, as a result of which holders of the Securities could lose all or part of the value of their investment in the Securities.”

We currently only publicly report the Group’s fully loaded CET1 Ratio quarterly as of the period end, and therefore during the quarterly period there is no published updating of the Group’s fully loaded CET1 Ratio and there may be no prior warning of adverse changes in the Group’s fully loaded CET1 Ratio. However, any indication that the Group’s fully loaded CET1 Ratio is moving towards the level of a Capital Adequacy Trigger Event may have an adverse effect on the market price of the Securities. A decline or perceived decline in the Group’s fully loaded CET1 Ratio may significantly affect the trading price of the Securities.

S-39

The circumstances surrounding or triggering an Automatic Conversion are unpredictable, and there are a number of factors that could affect the Group’s fully loaded CET1 Ratio.

The occurrence of a Capital Adequacy Trigger Event is inherently unpredictable and depends on a number of factors, including those discussed in greater detail in the following paragraphs, any of which may be outside the Issuer’s control. Although the Issuer currently publicly reports the Group’s fully loaded CET1 Ratio only as of each quarterly period end, a Capital Adequacy Trigger Event will occur if at any time the Group’s fully loaded CET1 Ratio is less than 7.00%. Whether a Capital Adequacy Trigger Event has occurred at any time shall be determined by the Issuer and such determination shall be binding on the Trustee and the holders of the Securities.

The Group’s fully loaded CET1 Ratio may fluctuate during a quarterly period. The calculation of such ratio could be affected by one or more factors, including, among other things, changes in the mix of the Group’s business, major events affecting the Issuer’s earnings, dividend payments by the Issuer, regulatory changes (including changes to definitions, interpretation and calculations of regulatory capital ratios and their components, including CET1 Capital and Risk Weighted Assets), revisions to models used by the Issuer to calculate its capital requirements (or revocation of, or amendments to, the regulatory permissions for using such models), and the Group’s ability to manage Risk Weighted Assets in both its ongoing businesses and those which it may seek to exit. In addition, the Group has capital resources and Risk Weighted Assets denominated in foreign currencies, and changes in foreign exchange rates will result in changes in the sterling equivalent value of foreign currency denominated capital resources and Risk Weighted Assets. As a result, the Group’s fully loaded CET1 Ratio is exposed to foreign currency movements.

The calculation of the Group’s fully loaded CET1 Ratio may also be affected by changes in applicable accounting rules, or by changes to regulatory adjustments which modify the regulatory capital impact of accounting rules. Moreover, even if changes in applicable accounting rules, or changes to regulatory adjustments which modify accounting rules, are not yet in force as of the relevant calculation date, the PRA could require us to reflect such changes in any particular calculation of the Group’s fully loaded CET1 Ratio.

Accordingly, accounting changes or regulatory changes may have a material adverse impact on the Group’s calculations of regulatory capital resources and requirements, including CET1 Capital and Risk Weighted Assets, and the Group’s fully loaded CET1 Ratio.

Because of the inherent uncertainty regarding whether a Capital Adequacy Trigger Event will occur, it will be difficult to predict when, if at all, an Automatic Conversion may occur. Accordingly, the trading behavior of the Securities is not necessarily expected to follow the trading behavior of other types of securities. Any indication that a Capital Adequacy Trigger Event (and subsequent Automatic Conversion) may occur can be expected to have a material adverse effect on the market price of the Securities.

In addition, any of the factors that affect the Group’s overall capital position, including those mentioned above, may in turn affect the Group’s capital, leverage and/or MREL resources, see “—The Capital Regulations impose capital and regulatory requirements that will restrict the Issuer’s ability to make discretionary distributions in certain circumstances, in which case the Issuer may reduce or cancel interest payments on the Securities. In addition, the PRA has broad powers to impose prudential requirements on the Issuer which may include requiring the Issuer to limit or cancel interest on the Securities” for a description of certain risks to the holders of a decrease in the Group’s capital, leverage and/or MREL resources.

The Group’s fully loaded CET1 Ratio, and more generally, its overall capital position, will be affected by the Group’s business decisions and, in making such decisions, its interests may not be aligned with those of the holders of the Securities.

As discussed in “—The circumstances surrounding or triggering an Automatic Conversion are unpredictable, and there are a number of factors that could affect the Group’s fully loaded CET1 Ratio” and

S-40

“—The Capital Regulations impose capital and regulatory requirements that will restrict the Issuer’s ability to make discretionary distributions in certain circumstances, in which case the Issuer may reduce or cancel interest payments on the Securities. In addition, the PRA has broad powers to impose prudential requirements on the Issuer which may include requiring the Issuer to limit or cancel interest on the Securities” above, the Group’s fully loaded CET1 Ratio, and, more generally, its overall capital position, could be affected by a number of factors. The Group’s fully loaded CET1 Ratio and its overall capital position will also depend on the Group’s decisions relating to its businesses and operations, as well as the management of its capital position. Neither the Issuer nor any member of the Group will have any obligation to consider the interests of the holders of the Securities in connection with its strategic decisions, including in respect of its capital management. Holders of the Securities will not have any claim against us or any other member of the Group relating to decisions that affect the business and operations of the Group, including the Group’s capital position, regardless of whether they result in the occurrence of mandatory distribution restrictions and/or a Capital Adequacy Trigger Event. Such decisions could cause holders of the Securities to lose all or part of the value of their investment in the Securities.

Future regulatory changes to the calculation of CET1 Capital and/or Risk Weighted Assets may negatively affect the Group’s fully loaded CET1 Ratio and thus increase the risk of a Capital Adequacy Trigger Event, which will lead to an Automatic Conversion, as a result of which holders of the Securities could lose all or part of the value of their investment in the Securities.

For the purposes of the Securities, the Issuer will determine the Group’s CET1 Capital and Risk Weighted Assets on a “fully loaded basis” without applying the transitional provisions set out in Part Ten of the U.K. CRD Regulation (which currently means the phase-in arrangements for the regulatory capital impact of IFRS 9). As a result, the Issuer’s CET1 Ratio may be lower than it would be were it to calculate the CET1 Ratio applying the IFRS 9 phase-in arrangements. Furthermore, the application of IFRS 9 is expected to result in greater changes from period to period in the level of provisions, which in turn would result in greater volatility over time in the Group’s income and consequently the Group’s CET1 Ratio.

As at March 31, 2024, the Group’s fully loaded CET1 Ratio was 13.4% while the Group’s CET1 Ratio calculated applying the IFRS 9 phase-in arrangements was 13.5%. The Group’s interpretation of the Capital Regulations and the basis of its determination of the Group’s fully loaded CET1 Ratio may be different from those of other financial institutions. For more information on how this ratio is determined, see the section entitled “Risk Review—Treasury and Capital risk” on pages 266-285 of the 2023 Form 20-F. For the purposes of the Securities, the calculation by the Issuer of the Group’s fully loaded CET1 Ratio (based on its interpretation of the Capital Regulations) at any time is binding on the Trustee and the holders of the Securities.

The requirements relating to capital ratios in the Capital Regulations may change whether as a result of further changes to U.K. CRD to complete the U.K. implementation of the remaining Basel III reforms, and/or changes to the way in which the PRA interprets and applies these requirements to U.K. banks and bank holding companies (including as regards individual model approvals granted by the PRA) and/or changes to the U.K. capital framework as a result of the U.K.’s withdrawal from the EU.

In addition, regulatory initiatives may impact the calculation of the Group’s Risk Weighted Assets, being the denominator of the CET1 Ratio. For example, in December 2017, the Basel Committee on Banking Supervision published proposed regulatory reforms including a standardized approach to the determination of risk weighted assets in “Basel III: Finalising post-crisis reforms” (the “BCBS package”). Broadly, the finalized BCBS package aims to: (i) strengthen risk sensitivity and comparability in credit risk by adopting minimum “input” floors for certain metrics; (ii) introduce a standardized approach to credit valuation adjustment risk; (iii) introduce a standardized approach to operational risk; (iv) provide safeguards against unsustainable levels of leverage by adding a leverage ratio buffer for global systemically important banks; and (v) ensure that banks’ “output” floors can be calculated as being 72.5% of total standardized approach RWAs. The date of implementation for most of the proposed reforms listed above had been set at January 1, 2022. However, the

S-41

Basel Committee on Banking Supervision has chosen to bring the output floor requirements into force over the course of an added five-year phased implementation period post January 1, 2022, ending on January 1, 2027. In March 2020, the oversight body of the Basel Committee on Banking Supervision, the Group of Central Bank Governors and Heads of Supervision (the “GHOS”) announced that it has endorsed a set of measures to provide additional operational capacity for banks and supervisors to respond to the immediate financial stability priorities resulting from the impact of the COVID-19 pandemic on the global banking system, including the deferral by one year to January 1, 2023 of the implementation date of most of the proposed reforms listed above and the deferral by one year to January 1, 2028 of the implementation period for the accompanying transitional arrangements for the output floor. In November 2022, the PRA published a consultation paper setting out its proposed rules for the implementation of the BCBS package, with a proposed implementation date of January 1, 2025 (subsequently extended to July 1, 2025) and full implementation by January 1, 2030 and HM Treasury (as defined below) published a consultation with the proposed secondary legislation to facilitate the implementation of such PRA rules. These proposals and resulting changes, either individually and/or in aggregate, may lead to further enhanced requirements in relation to the Group’s capital, leverage, liquidity and funding ratios or alter the way such ratios are calculated.

Therefore, any changes that may occur in the application of the Capital Regulations subsequent to the date of this prospectus supplement and/or any subsequent changes to such rules and other variables may individually and/or in the aggregate negatively affect the Group’s fully loaded CET1 Ratio and thus increase the risk of a Capital Adequacy Trigger Event, the occurrence of which would lead to an Automatic Conversion, as a result of which you could lose all or part of the value of your investment in the Securities.

Failure to meet the requirements of regulatory stress tests could result in the Group taking steps to improve its capital position and may otherwise adversely affect the Group.

The Group and certain of its members are subject to supervisory stress testing exercises in a number of jurisdictions. These exercises currently include the programs of the Bank of England, the EBA, the Federal Deposit Insurance Corporation and the Federal Reserve Bank of New York. These exercises are designed to assess the resilience of banks to adverse economic or financial developments and ensure that they have robust, forward-looking capital planning processes that account for the risks associated with their business profile. Assessment by regulators is on both a quantitative and qualitative basis, the latter focusing on the Group’s, or certain of its members’ business model, data provision, stress testing capability and internal management processes and controls.

Failure to meet requirements of regulatory stress tests, or the failure by regulators to approve the stress test results and capital plans of the Group, could result in the Group or certain of its members being required to enhance their capital position, including, for example, an additional PRA buffer which may be set by the PRA in certain circumstances, as set out in the PRA’s Policy Statement PS17/15 (Assessing capital adequacy under Pillar 2) and the related Statement of Policy (The PRA’s methodologies for setting Pillar 2 capital). This may result in a need for management actions, such as reducing capital and/or leverage exposures and/or taking steps to conserve capital, which could include reducing discretionary payments (for example, potentially exercising the Issuer’s discretion to cancel (in whole or in part) interest payments in respect of the Securities).

We may redeem the Securities at our option in certain situations.

We may, at our option, at any time, redeem the Securities, in whole but not in part, at a price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation” below) to (but excluding) the date fixed for redemption, if a Regulatory Event or a Tax Event has occurred, as more particularly described under “Description of Fixed Rate

Resetting Perpetual Subordinated Contingent Convertible Securities—Redemption—Regulatory Event Redemption” and “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible

S-42

Securities—Redemption—Tax Redemption,” respectively. In addition, if, at any time from the fifth anniversary of the Issue Date (unless otherwise permitted by the PRA), the outstanding aggregate principal amount of the Securities is 25% or less of the aggregate principal amount of the Securities originally issued, we may redeem all (but not some only) of the outstanding Securities at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation” below) to (but excluding) the date fixed for redemption, as more particularly described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Redemption—Clean-Up Call” below.

In addition, we may, at our option, redeem the Securities, in whole but not in part, on (i) any day falling in the period commencing on (and including) June 15, 2030, and ending on (and including) the first Reset Date or (ii) any day falling in the period commencing on (and including) the date that is six months before any subsequent Reset Date and ending on (and including) such Reset Date at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation” below) to (but excluding) the date fixed for redemption. The Issuer may choose to redeem the Securities at times when prevailing interest rates may be relatively low or in other circumstances favorable to the Issuer. If we redeem the Securities, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the Securities. In addition, any redemption of the Securities is subject to among other conditions, receipt of the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations), regardless of whether such redemption would be favorable or unfavorable to you.

Furthermore, holders of the Securities have no right to request the redemption of the Securities and should not invest in the Securities in the expectation that the Issuer would exercise its option to redeem the Securities. Any decision by the Issuer as to whether it will exercise its option to redeem the Securities will be taken at the absolute discretion of the Issuer with regard to factors such as, but not limited to, the economic impact of exercising such option to redeem the Securities, any tax consequences, the regulatory capital requirements and the prevailing market conditions.

We may substitute the Securities or vary their terms without the consent of holders.

Following the occurrence of a Regulatory Event or Tax Event, we may also, at our option and without the consent or approval of the holders or Trustee, either substitute all (but not some only) of the Securities for, or vary the terms of the Securities so that they remain or, as appropriate, become, Compliant Securities as more particularly described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Substitution or Variation” below. While Compliant Securities are required to contain terms not materially less favorable to investors than the terms of the Securities, this test will be deemed satisfied where the criteria set out in the definition of Compliant Securities is met. Despite the satisfaction of the relevant criteria, there can be no assurance that, whether due to the particular circumstances of a holder or otherwise, such Compliant Securities will not negatively affect any particular holder in any respects. In addition, the substitution or variation of the Securities may result in tax or stamp duty consequences for holders. The tax and stamp duty consequences of holding the Compliant Securities could be different for holders from the tax and stamp duty consequences for them of holding the Securities prior to such substitution or variation.

There can be no assurance as to how the terms of any Compliant Securities resulting from any such substitution or variation will be viewed by the market or whether any such Compliant Securities will trade at prices that are at least equivalent to the prices at which the substituted or varied Securities would have traded on the basis of their original. Therefore, there can be no assurance that the Compliant Securities will not have a significant adverse impact on the price of, and/or market for, the Securities or the circumstances of individual

S-43

holders. In addition, any such substitution or variation could have unexpected commercial consequences depending on the circumstances of an individual holder.

Our obligations under the Securities will be unsecured and subordinated, and the rights of the holders of Conversion Shares will be further subordinated.

Our obligations under the Securities will be unsecured and subordinated to all of the Issuer’s existing and future obligations to Senior Creditors (as defined under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Ranking” below). In addition, payment of principal or interest in respect of the Securities cannot be made in respect of the Securities except to the extent that the Issuer could make such payment and still satisfy the Solvency Condition (as defined under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Ranking” below) immediately thereafter. The Insolvency Act splits a financial institution’s non-preferential debts into classes, and provides that ordinary non-preferential debts will rank ahead of secondary non-preferential debts and tertiary non-preferential debts. The Securities constitute tertiary non-preferential debts under the terms of the Insolvency Act, and therefore both ordinary and secondary non-preferential debts would continue to rank ahead of claims in respect of the Securities.

If (a) an order is made, or an effective resolution is passed, for the winding-up of the Issuer (except in any such case for a solvent winding-up solely for the purpose of a merger, reconstruction or amalgamation); or (b) following the appointment of an administrator of the Issuer, the administrator gives notice that it intends to declare and distribute a dividend, then, (1) if such events specified in (a) or (b) above occur before the date on which a Capital Adequacy Trigger Event occurs, there shall be payable by the Issuer in respect of each Security (in lieu of any other payment by the Issuer) such amount, if any, as would have been payable to a holder of Securities if, on the day prior to the commencement of such winding-up or administration and thereafter, such holder of Securities were the holder of the most senior class of preference shares in the capital of the Issuer, having an equal right to a return of assets in such winding-up or administration to, and so ranking pari passu with, the holders of such class of preference shares (if any) from time to time issued by the Issuer that has a preferential right to a return of assets in such winding-up or administration, and so ranking ahead of the holders of all other classes of issued shares for the time being in the capital of the Issuer, but ranking junior to the claims of Senior Creditors, and on the assumption that the amount that such holder of Securities was entitled to receive in respect of such preference shares, on a return of assets in such winding-up or administration, was an amount equal to the principal amount of the relevant Security together with any damages (if payable) and (2) if such events specified in (a) or (b) above occur on or after the date on which a Capital Adequacy Trigger Event occurs but before the Conversion Date, then for the purposes of determining the claim of a holder in such winding-up or administration, the Conversion Date in respect of an Automatic Conversion shall be deemed to have occurred immediately before the occurrence of such events specified in (a) or (b) above.

Therefore, if the Issuer were to be wound up or placed into administration, the Issuer’s liquidator or administrator would first apply assets of the Issuer to satisfy all rights and claims of Senior Creditors. If the Issuer does not have sufficient assets to settle claims of such Senior Creditors in full, the claims of the holders of the Securities will not be settled and, as a result, the holders of the Securities will lose the entire amount of their investment in the Securities. In such winding-up or administration, the Securities will share equally in payment with claims under Parity Securities (or, with claims in respect of ordinary shares, in the event of a winding-up or administration occurring in the intervening period between a Capital Adequacy Trigger Event and the Conversion Date) if the Issuer does not have sufficient funds to make full payments on all of them, as applicable. In such a situation, holders of the Securities could lose all or part of their investment. See also “—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities.”

S-44

Furthermore, holders of the Securities should be aware that, upon the occurrence of an Automatic Conversion, all of the Issuer’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities), and each holder will be effectively further subordinated due to the change in their status on a winding-up or administration after the Conversion Date from being the holder of a debt instrument ranking ahead of holders of ordinary shares to being the holder of ordinary shares of the Issuer or the beneficial owner of ordinary shares of the Issuer as evidenced by the Security. As a result, upon the occurrence of an Automatic Conversion, the holders could lose all or part of their investment in the Securities irrespective of whether the Issuer has sufficient assets available to settle what would have been the claims of the holders of the Securities or other securities subordinated to the same extent as the Securities, in winding-up proceedings or otherwise. Therefore, even if other securities that rank pari passu with the Securities are paid in full, following the Conversion Date in respect of an Automatic Conversion, the holders will have no rights to the repayment of the principal amount of the Securities or the payment of interest on the Securities and will rank as holders of ordinary shares of the Issuer (or beneficial owners of ordinary shares of the Issuer).

Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities.

The tools and powers described below are in addition to the operation of the Automatic Conversion upon the occurrence of a Capital Adequacy Trigger Event pursuant to the terms of the Securities and could be exercised by the Relevant U.K. Resolution Authority at any time if the relevant pre-conditions are met (including before a Capital Adequacy Trigger Event occurs).

The Issuer and the Group are subject to substantial resolution powers.

Under the Banking Act substantial powers are granted to the Bank of England (or, in certain circumstances, His Majesty’s Treasury (“HM Treasury”)), in consultation with the PRA, the FCA and HM Treasury, as appropriate as part of a special resolution regime (the “SRR”). These powers enable the Relevant U.K. Resolution Authority to implement various resolution measures and stabilization options (including, but not limited to, the bail-in tool) with respect to a U.K. bank or investment firm and certain of its affiliates (as of the date of this prospectus supplement, including the Issuer) (each a “relevant entity”) in circumstances in which the Relevant U.K. Resolution Authority is satisfied that the relevant resolution conditions are met.

The SRR consists of five stabilization options: (i) private sector transfer of all or part of the business or shares of the relevant entity, (ii) transfer of all or part of the business of the relevant entity to a “bridge bank” established by the Bank of England, (iii) transfer to an asset management vehicle wholly or partly owned by HM Treasury or the Bank of England, (iv) the bail-in tool (as described below) and (v) temporary public ownership (nationalization).

The Banking Act also provides for additional insolvency and administration procedures for relevant entities and for certain ancillary powers, such as the power to modify contractual arrangements in certain circumstances (which could include a variation of the terms of the Securities), powers to impose temporary suspension of payments, powers to suspend enforcement or termination rights that might be invoked as a result of the exercise of the resolution powers and powers for the Relevant U.K. Resolution Authority to disapply or modify laws in the U.K. (with possible retrospective effect) to enable the powers under the Banking Act to be used effectively.

Holders of the Securities should assume that, in a resolution situation, financial public support will only be available to a relevant entity as a last resort after the Relevant U.K. Resolution Authority has assessed and used, to the maximum extent practicable, the resolution tools, including the bail-in tool.

S-45

The exercise of any resolution power or any suggestion of any such exercise could materially adversely affect the value of the Securities and could lead to holders of the Securities losing some or all of the value of their investment in the Securities.

Resolution powers triggered prior to insolvency may not be anticipated and holders may have only limited rights to challenge them.

The resolution powers conferred by the SRR are intended to be used prior to the point at which any insolvency proceedings with respect to the relevant entity could have been initiated. The purpose of the resolution powers is to address the situation where all or part of a business of a relevant entity has encountered, or is likely to encounter, financial difficulties, giving rise to wider public interest concerns.

Although the Banking Act provides specific conditions to the exercise of any resolution powers, it is uncertain how the Relevant U.K. Resolution Authority would assess such conditions in any particular pre-insolvency scenario affecting the Issuer and/or other members of the Group and in deciding whether to exercise a resolution power.

The Relevant U.K. Resolution Authority is also not required to provide any advance notice to holders of the Securities of its decision to exercise any resolution power. Therefore, holders of the Securities may not be able to anticipate a potential exercise of any such powers nor the potential effect of any exercise of such powers on the Issuer, the Group and the Securities.

Furthermore, holders of the Securities may have only limited rights to challenge and/or seek a suspension of any decision of the Relevant U.K. Resolution Authority to exercise its resolution powers (including the bail-in tool) or to have that decision reviewed by a judicial or administrative process or otherwise.

The Relevant U.K. Resolution Authority may exercise the bail-in tool in respect of the Issuer and the Securities, which may result in holders of the Securities losing some or all of their investment.

Where the relevant statutory conditions for use of the bail-in tool have been met, the Relevant U.K. Resolution Authority would be expected to exercise these powers without the consent of the holders. The Banking Act specifies the order in which the bail-in tool should be applied, reflecting the hierarchy of capital instruments under applicable U.K. legislation and rules and otherwise respecting the hierarchy of claims in an ordinary insolvency. Any such exercise of the bail-in tool in respect of the Issuer and the Securities may result in the cancellation of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Securities and/or the conversion of the Securities into shares or other securities or other obligations of the Issuer or another person, or any other modification or variation to the terms of the Securities.

The exercise of the bail-in tool in respect of the Issuer and the Securities or any suggestion of any such exercise could materially adversely affect the rights of the holders of the Securities, the price or value of their investment in the Securities and/or the ability of the Issuer to satisfy its obligations under the Securities and could lead to holders of the Securities losing some or all of the value of their investment in the Securities. The bail-in tool contains an express safeguard (known as “no creditor worse off”) with the aim that shareholders and creditors do not receive a less favorable treatment than they would have received in ordinary insolvency proceedings. However, even in circumstances where a claim for compensation is established under the “no creditor worse off” safeguard in accordance with a valuation performed after the resolution action has been taken, it is unlikely that such compensation would be equivalent to the full losses incurred by the holders of the Securities in the resolution and there can be no assurance that holders of the Securities would recover such compensation promptly.

S-46

Mandatory write-down and conversion of capital instruments may affect the Securities.

In addition, the Banking Act grants the power to the Relevant U.K. Resolution Authority to cancel, transfer or dilute Common Equity Tier 1 instruments, permanently write-down, or convert into equity, Additional Tier 1 Capital instruments (such as the Securities), Tier 2 Capital instruments and internal eligible liabilities at the point of non-viability of the relevant entity and before, or together with, the exercise of any resolution powers conferred by the SRR (except in the case where the bail-in tool is to be utilized for other liabilities, in which case such capital instruments or internal eligible liabilities would be written down or converted into equity pursuant to the exercise of the bail-in tool, as described above, rather than the mandatory write-down and conversion power).

Holders of the Securities may be subject to write-down or conversion into equity on application of such powers (without requiring the consent of such holders), which may result in such holders losing some or all of their investment or the Securities being converted into ordinary shares at a rate that may deliver fewer ordinary shares than if the Securities were to be converted into ordinary shares in accordance with their terms. The “no creditor worse off” safeguard would not apply in relation to an application of such powers to capital instruments such as these Securities in circumstances where resolution powers are not also exercised.

The exercise of such mandatory write-down and conversion power under the Banking Act or any suggestion of such exercise could, therefore, materially adversely affect the rights of holders of the Securities, the price or value of their investment in the Securities and/or the ability of the Issuer to satisfy its obligations under the Securities.

See “—The Issuer is a holding company, which means that its right to participate in the assets of any of its subsidiaries (including those of BBPLC, BBUKPLC, Barclays Execution Services Limited or any other present or future subsidiary) upon the liquidation of such subsidiaries, and the extent to which the Issuer suffers losses if it or any of its subsidiaries are subject to bank resolution proceedings, may depend, amongst other things, upon the degree to which the Issuer’s loans to, and investments in, such subsidiaries are subordinated” for a description of the risks relating to and arising from the Issuer’s rights to participate in the assets of its subsidiaries and the effect of the exercise of such mandatory write-down and conversion power in respect of such subsidiaries.

For a description of the relevant underlying regulatory background, including the bail-in tool and the mandatory write-down and conversion power, see the section entitled “Risk Review—Supervision and Regulation” on pages 290-299 of the 2023 Form 20-F.

Under the terms of the Securities, you agree to be bound by the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority.

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between us and any holder or beneficial owner of the Securities or the Trustee on behalf of the holders of the Securities, by acquiring the Securities, each holder and beneficial owner of the Securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the Relevant U.K. Resolution Authority that may result in (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, the Securities; (ii) the conversion of all, or a portion of, the principal amount of, or interest on, the Securities into shares or other securities or other obligations of the Issuer or another person (and the issue to, or conferral on, the holder or beneficial owner of the Securities, of such shares, securities or obligations); (iii) the cancellation of the Securities; and/or (iv) the amendment or alteration of the maturity, if any, of the Securities, or the amendment of the amount of interest due on the Securities, or the dates on which interest becomes payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Securities solely to give effect to the exercise by the Relevant U.K. Resolution Authority of such U.K. Bail-in Power. Each holder of the Securities further acknowledges and agrees that the rights of the holders of the Securities are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority.

S-47

Accordingly, any U.K. Bail-in Power may be exercised in such a manner as to result in you and other holders of the Securities losing all or a part of the value of your investment in the Securities or receiving a different security from the Securities, which may be worth significantly less than the Securities and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the Relevant U.K. Resolution Authority may exercise the U.K. Bail-in Power without providing any advance notice to, or requiring the consent of, the holders of the Securities. In addition, under the terms of the Securities, the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Securities is not a Winding-up Event or a default in payment. For more information, see “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” below and “Description of Contingent Capital Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” in the accompanying prospectus. See also “—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the Relevant U.K. Resolution Authority of a variety of statutory resolution powers, could materially adversely affect the value of the Securities.”

The Resolvability Assessment Framework could impact market perceptions of the Issuer and/or the Group and in turn affect the value of the Securities.

The Banking Act and associated FCA and PRA rules contain requirements relating to recovery and resolution plans, early supervisory interventions and the resolution of firms (including the bail-in tool).

The Bank of England and the PRA rules on a resolvability assessment framework (the “Resolvability Assessment Framework”) require the largest U.K. banks (including the Group) to carry out realistic assessments of their preparations for resolution. Summaries of the same and the Bank of England’s assessment of such preparations are disclosed publicly. The outcomes of complying with the Resolvability Assessment Framework from time to time and any possible regulatory or other actions deriving thereof may affect the way in which the Issuer and/ or the Group is perceived by the market, which in turn may affect the value of the Securities.

For further details on the Bank of England’s assessment on the Group’s 2021 self-assessment report published in June 2022, the timing in relation to the Group’s second self-assessment and a description of the relevant underlying regulatory background, see the section entitled “Risk Review—Supervision and regulation” on pages 290-299 of the 2023 Form 20-F.

Holders of the Securities will have limited remedies.

Payment of principal on the Securities shall be accelerated only in the event of certain events of a winding-up or administration involving us that constitute a Winding-up Event before the occurrence of a Capital Adequacy Trigger Event. Under the terms of the Indenture, a “Winding-up Event” results if either (i) a court of competent jurisdiction in England (or such other jurisdiction in which we may be organized) makes an order for our winding-up which is not successfully appealed within 30 days of the making of such order, (ii) our shareholders adopt an effective resolution for our winding-up (other than, in the case of either (i) or (ii) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (iii) following the appointment of an administrator, the administrator gives notice that it intends to declare and distribute a dividend. There is no right of acceleration in the case of non-payment of principal or interest on the Securities or of our failure to perform any of our obligations under or in respect of the Securities.

The sole remedy against us available for recovery of amounts owing in respect of any non-payment of any amount that has become due and payable under the Securities is, subject to certain conditions and to the provisions set forth in “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Enforcement Events and Remedies—Trust Indenture Act remedies” below, for the Trustee to institute proceedings in England (or such other jurisdiction in which we may be organized) (but not elsewhere) for our winding-up and/or prove in our winding-up and/or claim in our liquidation or administration.

S-48

Although the Trustee may institute such proceedings against us as it may think fit to enforce any term, obligation or condition binding on us under the Securities or the Indenture (other than any payment obligation of the Issuer under or arising from the Securities or the Indenture, including, payment of any principal or interest, including Contingent Capital Additional Amounts) (referred to herein as “Performance Obligations”), provided always that the Trustee (acting on behalf of the holders of the Securities) and the holders of the Securities may not enforce, and may not be entitled to enforce or otherwise claim, against the Issuer any judgment or other award given in such proceedings that requires the payment of money by the Issuer, whether by way of damages or otherwise (a “Monetary Judgment”), except by proving such Monetary Judgment in a winding-up of the Issuer and/or by claiming such Monetary Judgment in an administration of the Issuer.

For the avoidance of doubt, the sole and exclusive manner by which the Trustee (acting on behalf of holders of the Securities) and the holders of the Securities may seek to enforce or otherwise claim a Monetary Judgment against the Issuer in connection with the Issuer’s breach of a Performance Obligation shall be by proving such Monetary Judgment in a winding-up of the Issuer and/or by claiming such Monetary Judgment in an administration of the Issuer. By its acquisition of the Securities, each holder of the Securities acknowledges and agrees that such holder will not seek to enforce or otherwise claim, and will not direct the Trustee (acting on behalf of the holders of the Securities) to enforce or otherwise claim, a Monetary Judgment against the Issuer in connection with the Issuer’s breach of a Performance Obligation, except by proving such Monetary Judgment in a winding-up of the Issuer and/or by claiming such Monetary Judgment in an administration of the Issuer.

The remedies under the Securities are more limited than those typically available to our unsubordinated creditors.

No interest will be due and payable if such interest has been cancelled or deemed cancelled (in each case, in whole or in part) as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation” below. Accordingly, no default in payment or otherwise under the Securities will have occurred or be deemed to have occurred in such circumstances.

Following the occurrence of an Automatic Conversion, all of the Issuer’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date, and no principal or interest can become due and payable after such date. An Automatic Conversion will not constitute a default or a Winding-up Event under the Indenture.

Under the terms of the Indenture, the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Securities is not a Winding-up Event, a Non-Payment Event, a default in payment or otherwise.

For further detail regarding the limited remedies of the Trustee and the holders of the Securities, see “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Enforcement Events and Remedies” and “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Trustee’s Duties” in this prospectus supplement.

Waiver of set-off

Holders of the Securities waive any right of set-off, compensation, counterclaim, retention and netting in relation to the Securities insofar as permitted by applicable law. Therefore, holders of the Securities will not be entitled (subject to applicable law) to exercise, claim or plead any right of set-off, compensation, counterclaim, retention or netting in respect of the Issuer’s obligations under the Securities against obligations owed by them to the Issuer. Holders of the Securities may therefore be required to initiate separate proceeding to recover amounts in respect of any counterclaim and may receive a lower recovery in the event of a winding-up or administration of the Issuer than if set-off, compensation, counterclaim, retention or netting were permitted.

S-49

Changes in law may adversely affect the rights of holders of the Securities.

Changes in law after the date hereof may affect the rights of holders as well as the market value of the Securities. Such changes in law may include changes in statutory, tax and regulatory regimes during the life of the Securities, which may have an adverse effect on an investment in the Securities.

In addition, any change in law or regulation that triggers a Regulatory Event or a Tax Event would entitle us, at our option (subject to, amongst other conditions, receipt of the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations)), to redeem the Securities, in whole but not in part, as more particularly described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Redemption—Regulatory Event Redemption” and “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Redemption—Tax Redemption” respectively.

Such legislative and regulatory uncertainty could also affect an investor’s ability to accurately value the Securities and, therefore, affect the trading price of the Securities given the extent and impact on the Securities that one or more regulatory or legislative changes, including those described above, could have on the Securities.

The financial services industry has been and continues to be the focus of significant regulatory change and scrutiny (for example, the recent enactment in the U.K. of the Financial Services and Markets Act 2023 and the Retained EU Law (Revocation and Reform) Act 2023), which may adversely affect the Group’s business, financial performance, capital and risk management strategies—see the section entitled “Risk Review—Material existing and emerging risks—iv) Regulatory change agenda and impact on business model” on pages 188-189 of the 2023 Form 20-F for more detail. Such regulatory changes may include higher capital and additional loss absorbency requirements and increased powers of competent authorities. Such changes, and the resulting actions taken to address such regulatory changes, may have an adverse impact on the Group’s, and therefore the Issuer’s, performance and financial condition. It is not yet possible to predict the detail of such legislation or regulatory rulemaking or the ultimate consequences to the Group or the holders of the Securities which could be material to the rights of holders of the Securities and/or the ability of the Issuer to satisfy its obligations under the Securities.

There is no restriction on the amount or type of further securities or indebtedness that the Issuer or its subsidiaries may issue, incur or guarantee.

Subject to complying with applicable regulatory requirements in respect of the Group’s leverage and capital ratios, there is no restriction on the amount or type of further securities or indebtedness that the Issuer or its subsidiaries may issue, incur or guarantee, as the case may be, that rank senior to, or pari passu with, the Securities. The issue or guaranteeing of any such further securities or indebtedness may reduce the amount recoverable by holders of the Securities on a liquidation or winding-up of the Issuer and may limit the Issuer’s ability to meet its obligations under the Securities. In addition, the Securities do not contain any restriction on the Issuer issuing securities that may have preferential rights to the Securities or securities with similar or different provisions to those described herein.

Prior to the Conversion Date, holders will not be entitled to any rights with respect to the Issuer’s ordinary shares, but will be subject to all changes made with respect to the Issuer’s ordinary shares.

The exercise of voting rights and certain other rights related to any Conversion Shares is only possible after the issue, registration and delivery of the Conversion Shares on the Conversion Date to the Conversion Shares Depository (or the relevant recipient) in accordance with the provisions of, and subject to the limitations provided in, the articles of association of the Issuer and under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Automatic Conversion Upon Capital Adequacy Trigger Event.” Prior to such issuance, registration and delivery, holders will be subject to all changes made with respect to the Issuer’s ordinary shares.

S-50

As a result of holders of the Securities receiving Conversion Shares upon the occurrence of a Capital Adequacy Trigger Event, they are particularly exposed to changes in the market price of the Issuer’s ordinary shares.

In general, investors in convertible or exchangeable securities may seek to hedge their exposure in the underlying equity securities at the time of acquisition of the convertible or exchangeable securities. Prospective investors in the Securities may look to sell ordinary shares of the Issuer in anticipation of taking a position in, or whilst holding, the Securities. This could drive down the price of the Issuer’s ordinary shares. Since the Securities will mandatorily convert into Conversion Shares upon the occurrence of a Capital Adequacy Trigger Event, the price of the Issuer’s ordinary shares may be more volatile if the Issuer is trending toward a Capital Adequacy Trigger Event.

There may not be any trading market for the Securities.

The Securities are a new issue of securities and have no established trading market. Although application will be made to have the Securities admitted to listing and to trading on the ISM, there can be no assurance that an active trading market will develop. Even if an active trading market does develop, it may not be liquid and may not continue for the term of the Securities. The liquidity and the market prices for the Securities can be expected to vary with changes in market and economic conditions, the Group’s financial condition and prospects and other factors that generally influence the market prices of securities. If the secondary market for the Securities is limited, there may be few buyers and this may reduce the relevant market price of the Securities.

There can be no assurance that events in the U.K. or elsewhere will not cause market volatility or that such volatility will not adversely affect the price of the Securities or that economic and market conditions will not have any other adverse effect on the Securities.

A downgrade of the credit rating assigned by any credit rating agency to the Issuer or to the Securities could adversely affect the liquidity or market value of the Securities. Credit ratings downgrades could occur as a result of, among other causes, changes in the ratings methodologies used by credit rating agencies.

Upon issuance, it is expected that the Securities will be rated by credit rating agencies and may in the future be rated by additional credit rating agencies, although the Issuer is under no obligation to ensure that the Securities are rated by any credit rating agency. Credit ratings may not reflect the potential impact of all risks related to structure, market, additional factors discussed in these Risk Factors and other factors that may affect the liquidity or market value of the Securities. A credit rating is not a recommendation to buy, sell or hold securities and may be revised, suspended or withdrawn by the credit rating agency at any time.

Any rating assigned to the Issuer and/or the Securities may be withdrawn entirely by a credit rating agency, may be suspended or may be lowered, if, in that credit rating agency’s judgment, circumstances relating to the basis of the rating so warrant. Ratings may be impacted by a number of factors which can change over time, including the credit rating agency’s assessment of: the Issuer’s strategy and management’s capability; the Issuer’s financial condition including in respect of capital, funding and liquidity; competitive and economic conditions in the Issuer’s key markets; the level of political support for the industries in which the Issuer operates; and legal and regulatory frameworks affecting the Issuer’s legal structure, business activities and the rights of its creditors. The credit rating agencies may also revise the ratings methodologies applicable to issuers within a particular industry or political or economic region. If credit rating agencies perceive there to be adverse changes in the factors affecting an issuer’s credit rating, including by virtue of changes to applicable ratings methodologies, the credit rating agencies may downgrade, suspend or withdraw the ratings assigned to an issuer and/or its securities. Revisions to ratings methodologies and actions on the Issuer’s ratings by the credit rating agencies may occur in the future.

If the Issuer determines to no longer maintain one or more ratings, or if any credit rating agency withdraws, suspends or downgrades the credit ratings of the Issuer or the Securities, or if such a withdrawal, suspension or

S-51

downgrade is anticipated (or any credit rating agency places the credit ratings of the Issuer or, if applicable, the Securities on “credit watch” status in contemplation of a downgrade, suspension or withdrawal), whether as a result of the factors described above or otherwise, such event could adversely affect the liquidity or market value of the Securities (whether or not the Securities had an assigned rating prior to such event).

The gross-up requirement is limited to payments of interest.

The requirement for the Issuer to pay additional amounts on the Securities (subject to the limitations and restrictions described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Interest Cancellation”) in respect of any withholding or deduction for or on account of taxes in the Taxing Jurisdiction (as defined in the accompanying prospectus) applies only to payments of interest on the Securities and not to payments of principal in respect of the Securities. As such, the Issuer would not be required to pay any additional amounts to the extent any withholding or deduction for or on account of taxes in the Taxing Jurisdiction is applied to payments of principal in respect of the Securities (including where the Taxing Jurisdiction treats any part of such principal as “interest” for tax purposes). Accordingly, if any such withholding or deduction were to apply to any payments of principal in respect of any Securities, holders shall only be entitled to the net amount of such payment after deduction of the amount required to be withheld or deducted. The market value of the Securities may be adversely affected as a result.

The Securities are not considered investment grade by some of the rating agencies and are subject to the risks associated with non-investment grade securities.

The Securities, upon issuance, will not be considered to be investment grade securities by some of the rating agencies. As such, they will be subject to a higher risk of price volatility than higher-rated securities. Furthermore, increases in leverage or deteriorating outlooks for the Issuer, or volatile markets, could lead to a significant deterioration in market prices of below-investment grade rated securities such as the Securities.

You may be subject to U.S. tax upon adjustments (or failure to make adjustments) to the Conversion Price even though you do not receive a corresponding cash distribution.

The Conversion Price is subject to adjustment in certain circumstances, as described under “Description of Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities—Anti-Dilution” below. If, as a result of adjustments (or failure to make adjustments), your proportionate interest in our assets or earnings were deemed to be increased for U.S. federal income tax purposes, you may be treated as having received a taxable distribution for these purposes, without the receipt of any cash or property. See “Tax Considerations—U.S. Federal Income Tax Consequences—Adjustment of the Conversion Price” for a further discussion of these U.S. federal tax implications.

You may be subject to FATCA withholding.

Under certain provisions of the U.S. Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder (commonly referred to as “FATCA”), as well as certain intergovernmental agreements between the United States and certain other countries (including the U.K.) together with local country implementing legislation, a 30% withholding tax may be imposed on all or some of the payments on the Securities and Conversion Shares, if those payments are treated as “foreign passthru payments”, to holders of the Securities and non-U.S. financial institutions receiving payments on behalf of such holders that, in each case, fail to comply with information reporting, certification and related requirements. Under current regulations, the term “foreign passthru payments” is not defined, and it is not yet clear whether or to what extent payments on the Securities and Conversion Shares may be subject to this withholding tax. However, the U.S. Internal Revenue Service (the “IRS”) has indicated that it will not apply withholding tax to any foreign passthru payments made prior to two years after the date on which final regulations on this issue are published. This withholding tax, if it applies, could apply to any payment made with respect to the Securities and Conversion Shares, including

S-52

payments of both principal and interest. Moreover, withholding may be imposed at any point in a chain of payments if a non-U.S. payee fails to comply with U.S. information reporting, certification and related requirements. Accordingly, Securities and Conversion Shares held through a non-compliant institution may be subject to withholding even if the holder of the Securities otherwise would not be subject to withholding.

If withholding is required in respect of this withholding tax, the Issuer will not be required to pay any additional amounts with respect to any amounts withheld. Holders of the Securities are urged to consult their tax advisers and any banks or brokers through which they will hold the Securities and Conversion Shares as to the consequences (if any) of these rules to them.

An investment in the Securities by a holder whose home currency is not sterling entails significant risks.

An investment in the Securities by a holder whose home currency is not sterling entails significant risks. These risks include the possibility of significant changes in rates of exchange between the holder’s functional currency and sterling and tax consequences as a result of any foreign exchange gains resulting from an investment in the Securities. These risks generally depend on factors over which we have no control, such as economic, financial and political events and the supply of and demand for the relevant currencies. In recent years, rates of exchange between sterling, on the one hand, and certain currencies, on the other, have been highly volatile, and each holder should be aware that volatility may be expected to continue in the future. Fluctuations in any particular rate of exchange that have occurred in the past, however, are not necessarily indicative of fluctuations in the rate that may occur during the term of the Securities. Depreciation of sterling against the holder’s functional currency would result in a decrease in the effective yield of the Securities below its coupon rate and, in certain circumstances, could result in a loss to the holder. If you are a beneficial owner of securities subject to U.S. federal income tax, see “Tax Considerations—U.S. Federal Income Tax Consequences” for certain U.S. federal income tax consequences related to the Securities being denominated in sterling.

In a lawsuit for payment on the Securities, holders of the Securities may bear currency exchange risk.

The Indenture is, and the Securities will be, governed by the laws of the State of New York, with certain limited exceptions. A New York state statute presently in effect would require a New York state court hearing such a lawsuit to render its decision or award in sterling. The judgment entered on that award, however, will be denominated in U.S. dollars, and converted at the exchange rate prevailing on the date of entry of the judgment. Consequently, subject to the limited remedies provided for in the terms of the Securities (see the risk factor above “—Holders of the Securities will have limited remedies”) in a lawsuit for payment on the Securities, if permitted under the Indenture and terms of the Securities, holders of such Securities would bear currency exchange risk until a New York state court judgment is entered, which could be a long time. A Federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the Securities would apply the foregoing New York law.

In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the Securities in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of sterling into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

The Securities will be represented by one global certificate that will be deposited with a common depositary for Clearstream, Luxembourg and/or Euroclear and registered in the name of such common depositary or its nominee and, therefore, holders of the Securities will have to rely on their procedures for transfer, payment and communication with us.

The Securities will be represented by one global certificate that will be deposited with a common depositary for Clearstream, Luxembourg and/or Euroclear and registered in the name of such common depositary or its

S-53

nominee. Except in certain limited circumstances described in the global certificate, holders of the Securities will not be entitled to receive Securities in definitive form in exchange for interests in the global certificate. While the Securities are represented by the global certificate, holders of the Securities will be able to trade their beneficial interests only through Clearstream, Luxembourg and/or Euroclear.

We will discharge our payment obligations under the Securities by making payments to or to the order of the common depositary for Clearstream, Luxembourg and/or Euroclear for distribution to their accountholders. A holder of a beneficial interest in a global certificate must rely on the procedures of Clearstream, Luxembourg and/or Euroclear to receive payments under the Securities. We have no responsibility or liability for the records relating to, or payments made in respect of, beneficial interests in the global certificate.

Holders of the Securities of beneficial interests in the global certificate will not have a direct right to vote in respect of the Securities. Instead, such holders will be permitted to act directly only to the extent that they are enabled in accordance with the procedures of Clearstream, Luxembourg and/or Euroclear to appoint appropriate proxies.

Trading in the Clearing Systems is subject to minimum denomination requirements.

The Securities will be issued only in minimum denominations of £200,000 and integral multiples of £1,000 in excess thereof. It is possible that the Clearing Systems may process trades which could result in amounts being held in denominations smaller than the minimum denominations. If Securities in definitive form are required to be issued in relation to such Securities in accordance with the provisions of the relevant global securities, a holder who does not have at least the minimum denomination of £200,000 or any integral multiple of £1,000 in excess thereof in its account with the relevant Clearing System at the relevant time may not receive its entitlement of Securities in definitive form unless and until such time as its holding satisfies the requirement of the minimum denomination of £200,000 or any integral multiple of £1,000 in excess thereof.

The market continues to develop in relation to near risk-free rates (including overnight rates).

Investors should be aware that the market continues to develop in relation to near risk-free rates (“RFRs”), such as SONIA as a reference rate in the capital markets for sterling, and their adoption as alternatives to the relevant interbank offered rates. This relates not only to the substance of the calculation and the development and adoption of market infrastructure for the issuance and trading of bonds referencing such rates, but also how widely such rates and methodologies might be adopted. RFRs, such as SONIA, may differ from interbank offered rates in a number of material components, including (without limitation) by being backwards-looking, calculated on a compounded or weighted average basis, near risk free, overnight rates.

In addition, market participants and relevant working groups have been working together to design alternative reference rates based on RFRs, including applying term versions of RFRs (which seek to measure the market’s forward expectation of an average of these RFRs over a designated term, as they are overnight rates) or different measures of such RFRs.

The market or a significant part thereof may adopt an application of SONIA that differs significantly from that underlying the rate set out in the terms of the Securities and used in relation to the Securities. If SONIA does not prove to be widely used in securities such as the Securities, the trading price of the Securities may be lower than those securities referencing rates that are more widely used. The development of RFRs for sterling bonds could result in reduced liquidity or increased volatility or could otherwise affect the market price of the Securities.

In addition, the manner of adoption or application of RFRs in the sterling bond market may differ materially compared with the application and adoption of RFRs in other markets, such as the derivatives and loan markets. Investors should carefully consider how any mismatch between the adoption of such reference rates in the bond,

S-54

loan and derivatives markets may impact any hedging or other financial arrangements which they may put in place in connection with any acquisition, holding or disposal of Securities. In addition, the methodology for determining SONIA could change during the life of the Securities.

Market terms for debt securities referencing SONIA, such as the Securities, may evolve over time, and trading prices of the Securities may be lower than those of later-issued SONIA indexed debt securities as a result. Investors in the Securities may not be able to sell the Securities at all or may not be able to sell the Securities at prices that will provide them with a yield comparable to similar investments that have a developed secondary market and may consequently suffer from increased pricing volatility and market risk.

RFRs offered as alternatives to interbank offered rates also have a limited history. For that reason, future performance of such rates may be difficult to predict based on their limited historical performance. The level of such rates after the Issue Date may bear little or no relation to historical levels. Prior observed patterns, if any, in the behavior of market variables and their relation to such rates such as correlations, may change in the future. Investors should not rely on historical performance data as an indicator of the future performance of such risk-free rates nor should they rely on any hypothetical data.

Investors should consider these matters when making their investment decision with respect to the Securities.

The administrator of SONIA may make changes that could change the value of SONIA or discontinue SONIA respectively.

The Bank of England (or its successor) as administrator of SONIA, may make methodological or other changes that could change the value of SONIA or any indices or rates linked to SONIA, including changes related to the method by which such rates and/or indices are calculated, eligibility criteria applicable to the transactions used to calculate such rates and/or indices, or timing related to the publication of SONIA. In addition, an administrator may alter, discontinue or suspend calculation or dissemination of SONIA, in which case a fallback method of determining the interest rate on the Securities will apply in accordance with the terms of the Securities (see “—Uncertainty relating to the regulation of “benchmark rates” may adversely affect the value of the Securities” below). The Bank of England has no obligation to consider the interests of holders of the Securities when calculating, adjusting, converting, revising or discontinuing SONIA.

Uncertainty relating to the regulation of “benchmark rates” may adversely affect the value of the Securities.

Interest rates or other types of rates and indices which are deemed to be “benchmark rates” are the subject of ongoing national and international regulatory review and reform, with further changes anticipated. These reforms have resulted in the cessation of certain benchmarks, including the sterling London Interbank Offered Rate (“LIBOR”) and the cessation of U.S. dollar LIBOR at the end of June 2023. Other benchmarks could be eliminated entirely or declared unrepresentative. Such reforms may cause benchmarks to perform differently than in the past, a benchmark could be eliminated entirely or declared unrepresentative, or there could be other consequences that cannot be predicted. Any such consequence could have a material adverse effect on the Securities.

Regulations in line with the global benchmark reforms could have a material impact on the Securities, in particular, if the methodology or other terms of the benchmark are changed in order to comply with the requirements of any such regulation. In each case, such changes could, among other things, have the effect of reducing or increasing the rate or level, or affect the volatility of, the published rate or level of benchmarks.

More broadly, any of the international or national reforms, or the general increase in regulatory scrutiny of benchmarks, could increase the costs and risks of administering or participating in the setting of a benchmark and

S-55

complying with any such regulations or requirements. Such factors may have the effect of discouraging market participants from continuing to administer or contribute to certain benchmarks, trigger changes in the rules or methodologies used in certain benchmarks or lead to the discontinuation or unavailability of quotes of certain benchmarks.

As the Securities may reference an affected benchmark, uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to such benchmark may adversely affect such benchmark rates and the return on, value of and the trading market for the Securities.

In accordance with the terms of the Securities, the Securities may be subject to the adjustment of the interest provisions in certain circumstances, such as the potential elimination of SONIA or the then applicable benchmark, an inability to obtain authorisation or registration by the administrator of SONIA or the then applicable benchmark, changes in the manner of administration of SONIA or the then applicable benchmark or the availability of a successor or replacement benchmark. The circumstances which could trigger such adjustments are beyond the Issuer’s control. The subsequent use of a replacement benchmark may result in changes to the terms of the Securities (which could be extensive) and/or interest payments that are lower than or that do not otherwise correlate over time with the payments that could have been made on the Securities if SONIA (or the then applicable benchmark) remained available in its current form.

Although pursuant to the terms of the Securities, spread adjustments may be applied to any such replacement benchmark in order to reduce or eliminate, to the extent reasonably practicable in the circumstances, any economic prejudice or benefit (as applicable) to investors arising out of the replacement of SONIA or the then applicable benchmark, the application of such adjustments to the Securities may not achieve this objective. Any such changes may result in the Securities performing differently (which may include payment of a lower interest rate) than if the original benchmark continued to apply. There is no assurance that the characteristics of any replacement benchmark would be similar to the affected benchmark, that any replacement benchmark would produce the economic equivalent of the affected benchmark or would be a suitable replacement for the affected benchmark. The choice of replacement benchmark is uncertain and could result in the use of other near risk-free rates (see “—The market continues to develop in relation to near risk free rates (including overnight rates)” above for the risks relating to the use of such rates) and/or in the replacement benchmark being unavailable or indeterminable.

In certain circumstances the ultimate fallback of interest for a particular Reset Period may result in the rate of interest for the immediately preceding Reset Period being used. This may result in the effective application of a fixed rate for the Securities based on the Rate of Interest for the previous Reset Period or the Initial Interest Rate, as applicable. Furthermore, if the Issuer determines it is not able to follow the prescribed steps set out in the terms of the Securities or that following such steps prejudices or, in certain circumstances, could reasonably be expected to prejudice, the then current capital or eligible liabilities qualification of the Securities, the relevant fallback provisions may not operate as intended at the relevant time. Any such consequence could have a material adverse effect on the trading markets for the Securities, the liquidity of the Securities and/or the value of and return on the Securities.

The terms of the Securities may require the exercise of discretion by the Issuer or an independent adviser, as the case may be, and the making of potentially subjective judgments (including as to the occurrence or not of any events which may trigger amendments to the terms of the Securities) and/or the amendment of the terms of the Securities without the consent of the holders of the Securities. The interests of the Issuer or those of the Independent Adviser, as applicable, in making such determinations or amendments may be adverse to the interests of the holders of the Securities.

Moreover, any of the above matters or any other significant change to the setting or existence of any relevant reference rate could affect the ability of the Issuer to meet its obligations under the Securities or could have a material adverse effect on the market value or liquidity of, and the amount payable under, the Securities.

DESCRIPTION OF FIXED RATE RESETTING PERPETUAL SUBORDINATED CONTINGENT CONVERTIBLE SECURITIES

The following description of the Securities supplements (and, where different from, supersedes) the description of the Securities in the accompanying prospectus. If this prospectus supplement is inconsistent with the accompanying prospectus, this prospectus supplement will prevail with regard to the Securities.

The Securities will constitute a series of Contingent Capital Securities issued under the Contingent Capital Securities Indenture dated as of August 14, 2018 among us and The Bank of New York Mellon, London Branch, as Trustee and The Bank of New York Mellon SA/NV, Luxembourg Branch, as Contingent Capital Security Registrar (as supplemented and amended through the Issue Date, the “Base Indenture”), as further supplemented by the eleventh supplemental indenture expected to be entered into on May 15, 2024 (the “Eleventh Supplemental Indenture,” and together with the Base Indenture, the “Indenture”). The terms of the Securities include those stated in the Indenture and any supplements thereto, and those terms made part of the Indenture by reference to the Trust Indenture Act. Certain terms used in this prospectus supplement, unless otherwise defined herein, have the meaning given to them in the Indenture. We filed the Contingent Capital Securities Indenture dated as of August 14, 2018 as an exhibit to the Form 6-K filed on August 14, 2018 (Film No. 181018017), and will file the Eleventh Supplemental Indenture as an exhibit to a report on Form 6-K on or about May 15, 2024.

The shareholders of the Issuer passed an ordinary resolution on May 3, 2023 to increase its share capital by the creation of new shares of up to £825,000,000 in relation to any issue of securities that automatically convert into or are exchanged for ordinary shares of the Issuer in prescribed circumstances where the directors of the Issuer consider that such an issuance of securities would be desirable in connection with, or for the purposes of, complying with or maintaining compliance with regulatory capital requirements or targets applicable to the Group from time to time, which authorization expires at the end of the Issuer’s Annual General Meeting to be held in 2024 or the close of business on June 30, 2024 (whichever is earlier), unless otherwise renewed or passed pursuant to a separate resolution.

The Securities will be issued in an aggregate principal amount of £1,250,000,000 and will have no fixed maturity or fixed redemption date. From (and including) the Issue Date to (but excluding) December 15, 2030, the interest rate on the Securities will be 8.500% per annum (the “Initial Interest Rate”). From (and including) each Reset Date to (but excluding) the next following Reset Date (each such period, a “Reset Period”), the applicable per annum interest rate (the “Subsequent Interest Rate”) will be equal to the sum, as determined by the Calculation Agent, of the applicable Mid-Market Swap Rate (such term subject to the provisions described under “—Determination of Subsequent Interest Rate” below) on the relevant Reset Determination Date and 4.881% (the “Margin”), converted to a quarterly rate in accordance with market convention as instructed by the Issuer (rounded to three decimal places, with 0.0005 rounded down). Subject to the conditions described under “—Interest Cancellation” below and to the last sentence of this paragraph, interest, if any, will be payable quarterly in arrear on March 15, June 15, September 15 and December 15 of each year (each an “Interest Payment Date”). The first date on which interest may be paid will be September 15, 2024 for the period commencing on (and including) May 15, 2024, and ending on (but excluding) September 15, 2024 (and thus a long first interest period). Subject to the conditions described herein, interest on the Securities, if any, will be computed and payable as set out under “—Day Count Fraction” below.

The regular record dates for the Securities will be the close of business on the Clearing System Business Day immediately preceding each Interest Payment Date (or, if the Securities are held in definitive form, the close of business on the 15th Business Day preceding each Interest Payment Date).

The Reset Dates are December 15, 2030 and each fifth (5th) anniversary thereafter.

The Reset Determination Date is the second Payment Business Day immediately preceding each Reset Date.

S-59

If any Interest Payment Date is not a Payment Business Day, we will pay interest on the next Payment Business Day, but interest on that payment will not accrue during the period from and after the Interest Payment Date. If a date of redemption is not a Payment Business Day, we may pay interest (if any) and principal on the next Payment Business Day, but interest on that payment will not accrue during the period from and after the date of redemption.

The term “Business Day” means any weekday, other than one on which banking institutions are authorized or obligated by law, regulation or executive order to close in London, U.K.

The term “Clearing System Business Day” means a day on which each Clearing System for which the global certificate is being held is open for business.

The term “Payment Business Day” means any day on which banks are open for general business (including dealings in foreign currencies) in London, U.K. or, if the Securities are held in definitive form, in the case of payment by transfer to a sterling account, any day on which dealings in foreign currencies may be carried on in London, U.K.; and in the case of surrender (or, in the case of part payment only, endorsement) of any Securities in definitive form, any day on which banks are open for general business (including dealings in foreign currencies) in the place in which the Securities in definitive form are surrendered (or, as the case may be, endorsed).

References to “you” and “holder” in the subsections “—Interest Cancellation,” “—Ranking,” “—Agreement with Respect to the Exercise of U.K. Bail-in Power,” “—Automatic Conversion Upon Capital Adequacy Trigger Event,” “—Definitions” and “—Subsequent Holders’ Agreement” below, and in “Certain Definitions” above, include beneficial owners of the Securities.

Currency of Payments

Initial holders of the Securities will be required to pay for the Securities in sterling, and principal and interest payments in respect of the Securities will be payable in sterling. If, on any date on which a payment in respect of the Securities is contemplated, sterling is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or is no longer used for the settlement of transactions by public institutions within the international banking community, then all payments in respect of the Securities will be made in U.S. dollars until sterling is again available to us or so used. The amount payable on any date in sterling will be converted into U.S. dollars at the Prevailing Rate as of the close of business on the second Payment Business Day prior to the relevant payment date.

Any payment in respect of the Securities so made in U.S. dollars will not constitute a Winding-up Event, a Non-Payment Event, a default in payment or otherwise under the Indenture or the Securities. Neither the Trustee, the Principal Paying Agent nor any other paying agent will be responsible for obtaining exchange rates, effecting currency conversions or otherwise handling redenominations.

General

Book-entry interests in the Securities will be issued in minimum denominations of £200,000 and in integral multiples of £1,000 in excess thereof (the denomination of each book-entry interest being the “Tradable Amount” of such book-entry interest). Prior to an Automatic Conversion, the aggregate Tradable Amount of the book-entry interests in each Security shall be equal to such Security’s principal amount. Following an Automatic Conversion, the principal amount of each Security shall be zero (as described below under “—Automatic Conversion Upon Capital Adequacy Trigger Event”) but the Tradable Amount of the book-entry interests in each Security shall remain unchanged.

S-60

The principal corporate trust office of the Trustee in the City of London, U.K. is designated as the principal paying agent. We may at any time designate additional paying agents or rescind the designation of paying agents or approve a change in the office through which any paying agent acts.

We will issue the Securities in registered form. The Securities will be represented by one global certificate that will be deposited with a common depositary for Clearstream, Luxembourg and/or Euroclear, and registered in the name of such common depositary or its nominee. You will hold beneficial interests in the Securities through Clearstream, Luxembourg and/or Euroclear and their respective direct and indirect participants and such direct and indirect participants will record your beneficial interests on their books. The underwriters expect to deliver the Securities through the facilities of the Clearing Systems on May 15, 2024. Settlement of the Securities will occur through Clearstream, Luxembourg and/or Euroclear for value on the Issue Date. Secondary market trading through Clearstream, Luxembourg and/or Euroclear will occur in the ordinary way following the applicable rules and operating procedures of the Clearing Systems. For information on Clearstream, Luxembourg’s or Euroclear’s book-entry systems, see “Clearance and Settlement” in the accompanying prospectus.

Definitive securities will only be issued in the limited circumstances described under “Description of Certain Provisions Relating to Debt Securities and Contingent Capital Securities—Special Situations When a Global Security Will Be Terminated” in the accompanying prospectus, provided that we shall not have the option described in the accompanying prospectus to determine in our sole discretion that the global certificate representing the Securities should be exchanged for definitive Securities in registered form.

Payment of principal of and interest (if any) on the Securities, so long as the Securities are represented by a global certificate, will be made in immediately available funds. Beneficial interests in the global certificate will trade, and secondary market trading activity in such interests will be settled, in accordance with the normal rules and operating procedures of Clearstream, Luxembourg and/or Euroclear. The Issuer currently expects such trading and settlement to continue in the period between the Conversion Date and the Suspension Date.

Notwithstanding the provisions set out in “Description of Contingent Capital Securities—Notices” in the accompanying prospectus, so long as the Securities are represented by a global certificate deposited with a depositary or a common depositary for Euroclear and/or Clearstream, Luxembourg, notices to holders of Securities represented by such global certificate may be given by delivery of the relevant notice to Euroclear and/ or Clearstream, Luxembourg and, in any case, such notices shall be deemed to have been given to holders of Securities on the date of dispatch to Euroclear and/or Clearstream, Luxembourg.

Any reference to “DTC” or “The Depository Trust Company” in “Description of Contingent Capital Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” in the accompanying prospectus shall be deemed a reference to the Clearing Systems.

Determination of Subsequent Interest Rate

Mid-Market Swap Rate and fallbacks

“Five-year Mid-Market Swap Rate Quotations” means, for any Reset Period, the arithmetic mean of the bid and offered rates for the annual fixed leg (calculated on an Actual/365 (Fixed) day count basis) of a fixed-for-floating sterling interest rate swap transaction which: (i) has a term of five years commencing on the applicable Reset Date; (ii) is in an amount that is representative of a single transaction in the relevant market at the relevant time with an acknowledged dealer of good credit in the swap market; and (iii) has a floating leg based on the overnight SONIA rate compounded for 12-months (calculated on an Actual/365 (Fixed) day count basis).

“Mid-Market Swap Rate” means, in relation to a Reset Date and the related Reset Determination Date:

S-61

“Reference Banks” means four major banks in the sterling swap, money, securities or other market most closely connected with the relevant Mid-Market Swap Rate, as selected by the Issuer on the advice of an investment bank of international repute.

“Reset Reference Bank Rate” means, in relation to a Reset Date and the related Reset Determination Date, the percentage rate determined by the Calculation Agent on the basis of the Five-year Mid-Market Swap Rate Quotations provided by each of the Reference Banks at approximately 11:00 a.m. (London time) on the relevant Reset Determination Date (or thereafter on such date), rounded, if necessary, to the nearest 0.001% (with 0.0005% being rounded upwards). If at least three Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be the arithmetic mean of such Five-year Mid-Market Swap Rate Quotations, eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest). If only two Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be the arithmetic mean of such Five-year Mid-Market Swap Rate Quotations. If only one Five-year Mid-Market Swap Rate Quotation is provided, the Reset Reference Bank Rate will be the quotation provided. If no Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be (i) in respect of the Reset Reference Bank Rate determined in respect of the Reset Date falling on December 15, 2030, 3.997% per annum or (ii) in respect of the Reset Reference Bank Rate determined in respect of any Reset Date other than December 15, 2030, the Mid-Market Swap Rate in respect of the immediately preceding Reset Date.

Benchmark Replacement Event

In addition to and notwithstanding the provisions in “Determination of Subsequent Interest Rate—Mid-Market Swap Rate and fallbacks” above, if the Issuer determines that a Benchmark Event has occurred or that there is a Successor Rate, in either case when any Subsequent Interest Rate (or the relevant component part thereof) remains to be determined by reference to the Reference Rate, then the Issuer may elect (acting in good faith and in a commercially reasonable manner) to apply the following provisions:

S-62

provided that the determination of any Successor Rate or Alternative Reference Rate or Adjustment Spread, and any other related changes to the Securities, shall be made in accordance with the relevant Capital Regulations (if applicable) and shall not prejudice the then current capital or eligible liabilities qualification of the Securities, as applicable, in each case for the purposes of and in accordance with the Capital Regulations.

S-63

None of the Trustee, the Principal Paying Agent, any other paying agent or the Calculation Agent shall have any duty to determine whether a Benchmark Event has occurred or that there is a Successor Rate.

For the purposes of this section:

“Adjustment Spread” means a spread (which may be positive or negative) or formula or methodology for calculating a spread, which the Independent Adviser (in consultation with the Issuer) or the Issuer (as applicable), determines is required to be applied to the Successor Rate or the Alternative Reference Rate (as applicable) in order to reduce or eliminate, to the extent reasonably practicable in the circumstances, any economic prejudice or benefit (as applicable) to the holders of Securities as a result of the replacement of the Reference Rate with the Successor Rate or the Alternative Reference Rate (as applicable) and is the spread, formula or methodology which:

“Alternative Reference Rate” means the rate that the Independent Adviser or the Issuer (as applicable) determines has replaced the Reference Rate in customary market usage in the international debt capital markets for the purposes of determining rates of interest in respect of bonds denominated in sterling and of a five year duration or, if the Independent Adviser or the Issuer (as applicable) determines that there is no such rate, such other rate as the Independent Adviser or the Issuer (as applicable) determines in its discretion (acting in good faith and in a commercially reasonable manner) is most comparable to the Reference Rate;

“Benchmark Event” means:

S-64

“Independent Adviser” means an independent financial institution of international repute or other independent financial adviser experienced in the international debt capital markets, in each case appointed by the Issuer at its own expense;

“Reference Rate” means (i) SONIA or (ii) (if applicable) any other Successor Rate or Alternative Reference Rate (or any component part(s) thereof) determined and applicable to the Securities pursuant to the earlier operation of the provisions in this section “—Determination of Subsequent Interest Rate—Benchmark Replacement Event”;

“Relevant Nominating Body” means, in respect of the Reference Rate:

“Successor Rate” means the reference rate (and related alternative screen page or source, if available) that the Independent Adviser or the Issuer (as applicable) determines is a successor to or replacement of the Reference Rate (for the avoidance of doubt, whether or not the Reference Rate has ceased to be available) which is formally recommended by any Relevant Nominating Body.

Day Count Fraction

If the Calculation Period is equal to or shorter than the Regular Period during which it falls, interest on the Securities, if any, will be computed and payable on the basis of the number of days in the Calculation Period, divided by the product of (1) the number of days in the Regular Period in which the Calculation Period falls and (2) four. If the Calculation Period is longer than one Regular Period, interest on the Securities, if any, will be computed and payable on the basis of the sum of: (A) the number of days in such Calculation Period falling in the Regular Period in which it begins divided by the product of (1) the number of days in such Regular Period and (2) four; and (B) the number of days in such Calculation Period falling in the next Regular Period divided by the product of (1) the number of days in such Regular Period and (2) four.

“Calculation Period” means the relevant period for which interest is to be calculated from (and including) the first day in such period to (but excluding) the last day in such period.

“Regular Period” means each period from (and including) any Interest Payment Date to (but excluding) the next Interest Payment Date.

Further Issues

We may, without the consent of the holders of the Securities, issue additional securities having the same ranking and same interest rate, interest cancellation terms, redemption terms, Conversion Price and other terms as the Securities described in this prospectus supplement except for the price to the public and issue date (the “additional securities”).

Any such additional securities, together with the Securities offered by this prospectus supplement, will constitute a single series of securities under the Indenture. There is no limitation on the amount of Securities or other debt securities that we or our subsidiaries may issue under the Indenture and there is no restriction on us issuing securities that may have preferential rights to the Securities or securities with similar or different provisions to those described herein.

S-65

Interest Cancellation

Interest Payments Discretionary

Interest on the Securities will be due and payable only at the sole discretion of the Issuer, and the Issuer shall have sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date. If the Issuer does not make an interest payment on the relevant Interest Payment Date (or if the Issuer elects to make a payment of a portion, but not all, of such interest payment), such non-payment shall evidence the Issuer’s exercise of its discretion to cancel such interest payment (or the portion of such interest payment not paid), and accordingly such interest payment (or the portion thereof not paid) shall not be due and payable.

If the Issuer provides notice to cancel a portion, but not all, of an interest payment and the Issuer subsequently does not make a payment of the remaining portion of such interest payment on the relevant Interest Payment Date, such non-payment shall evidence the Issuer’s exercise of its discretion to cancel such remaining portion of the interest payment, and accordingly such remaining portion of the interest payment shall also not be due and payable.

Because the Securities are intended to qualify as Additional Tier 1 Capital under U.K. CRD, the Issuer may cancel (in whole or in part) any interest payment at its discretion and may pay dividends on its ordinary or preference shares notwithstanding such cancellation. In addition, the Issuer may use such cancelled payments without restriction to meet its obligations as they fall due.

Restriction on Interest Payments

Subject to the extent permitted in the following paragraph in respect of partial interest payments, the Issuer shall not make an interest payment on the Securities on any Interest Payment Date (and such interest payment shall therefore be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date) if:

The Issuer may, in its sole discretion, elect to make a partial interest payment on the Securities on any Interest Payment Date, only to the extent that such partial interest payment may be made without breaching the restriction in the preceding paragraph.

The Issuer will be responsible for determining compliance with this restriction on interest payments and neither the Trustee nor any agent shall be required to monitor such compliance or to perform any calculations in connection therewith.

See also “—Agreement to Interest Cancellation” and “—Notice of Interest Cancellation” below.

S-66

Agreement to Interest Cancellation

By subscribing for, purchasing or otherwise acquiring the Securities, holders of the Securities acknowledge and agree that:

Interest will only be due and payable on an Interest Payment Date to the extent it is not cancelled or deemed cancelled in accordance with the provisions described under “—Interest Payments Discretionary” and “—Restriction on Interest Payments” above. Any interest cancelled or deemed cancelled (in each case, in whole or in part) in the circumstances described above shall not be due and shall not accumulate or be payable at any time thereafter, and holders of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation. The Issuer may use such cancelled payments without restriction to meet its obligations as they fall due.

Notice of Interest Cancellation

If practicable, we shall provide notice of any cancellation or deemed cancellation of interest (in whole or in part) to the holders of the Securities through the Clearing Systems (or, if the Securities are held in definitive form, to the holders at their addresses shown on the register for the Securities) and to the Trustee directly on or prior to the relevant Interest Payment Date. If practicable, we shall endeavor to provide such notice at least five (5) Business Days prior to the relevant Interest Payment Date. Failure to provide such notice will not have any impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed cancellation of interest, or give holders of the Securities any rights as a result of such failure.

Ranking

The Securities will constitute our direct, unsecured and subordinated obligations, ranking pari passu without any preference among themselves. In the event of our winding up or administration, the rights and claims of the holders of the Securities in respect of or arising from the Securities (including any damages (if payable)) will be subordinated to the claims of Senior Creditors.

If:

S-67

Furthermore, other than in the event of a winding-up or administration of the Issuer specified in (a) or (b) above, payments in respect of or arising from the Securities are conditional upon the Issuer being solvent at the time of payment by the Issuer and in that no sum in respect of or arising from the Securities may fall due and be paid except to the extent that the Issuer could make such payment and still be solvent immediately thereafter (such condition referred to herein as the “Solvency Condition”). For purposes of determining whether the Solvency Condition is met, the Issuer shall be considered to be solvent at a particular point in time if (i) it is able to pay its debts owed to Senior Creditors as they fall due and (ii) the Balance Sheet Condition (as defined herein) has been met.

An officer’s certificate executed in accordance with the Indenture as to the Issuer’s solvency at any particular point in time shall be treated by the Issuer, the Trustee, the holders of the Securities and all other interested parties as correct and sufficient evidence thereof.

Any payment of interest not due by reason of these provisions relating to ranking shall be deemed cancelled as provided under “—Interest Cancellation” above.

“Senior Creditors” means creditors of the Issuer (i) who are unsubordinated creditors; (ii) whose claims are, or are expressed to be, subordinated (whether only in the event of the winding-up or administration of the Issuer or otherwise) to the claims of unsubordinated creditors of the Issuer but not further or otherwise; (iii) who are creditors in respect of any secondary non-preferential debts; or (iv) whose claims are, or are expressed to be, junior to the claims of other creditors of the Issuer, whether subordinated or unsubordinated, other than those whose claims rank, or are expressed to rank, pari passu with, or junior to, the claims of the holders of the Securities.

“secondary non-preferential debts” shall have the meaning given to it in the Insolvency Act.

The “Balance Sheet Condition” shall be satisfied in relation to the Issuer if the value of its assets is at least equal to the value of its liabilities (taking into account its contingent and prospective liabilities), according to the criteria that would be applied by the High Court of Justice of England and Wales (or the relevant authority of such other jurisdiction in which the Issuer may be organized) in determining whether the Issuer is “unable to pay its debts” under section 123(2) of the Insolvency Act or any amendment or re-enactment thereof (or in accordance with the corresponding provisions of the applicable laws of such other jurisdiction in which the Issuer may be organized).

Because of the subordination described above, in the event of our winding-up in England (or in any other jurisdiction which we are incorporated), our Senior Creditors may recover more, ratably, than the holders of the Securities and any Parity Securities. Currently, we have no limitations on issuing indebtedness which would constitute the claims of Senior Creditors.

In addition, the Issuer is a holding company that currently has no significant assets other than its loans to, and investment in, its subsidiaries, including BBPLC and BBUKPLC. As a holder of ordinary shares in BBPLC

S-68

or BBUKPLC (or any of its other subsidiaries), the Issuer’s right to participate in the assets of BBPLC or BBUKPLC (or any other subsidiary) if such subsidiary is liquidated will be subject to the prior claims of such subsidiary’s third party creditors and preference shareholders, except in the limited circumstance where the Issuer is a creditor with claims that are recognized to be ranked pari passu with such claims of other of the subsidiary’s third party creditors and/or preference shareholders against such subsidiary. See “Risk Factors—Risks Relating to the Securities—The Issuer is a holding company, which means that its right to participate in the assets of any of its subsidiaries (including those of BBPLC, BBUKPLC, Barclays Execution Services Limited or any other present or future subsidiary) upon the liquidation of such subsidiaries and the extent to which the Issuer suffers losses if it or any of its subsidiaries are subject to bank resolution proceedings, may depend, amongst other things, upon the degree to which the Issuer’s loans to, and investments in, such subsidiaries are subordinated.”

No Set-off

Subject to applicable law, no holder of Securities may exercise, claim or plead any right of set-off, compensation, counterclaim, retention or netting in respect of any amount owed to it by us arising under, or in connection with, the Securities and the Indenture and each holder of Securities shall, by virtue of its holding of any Security (or any beneficial interest therein), be deemed, to the fullest extent permitted under applicable law, to have waived all such rights of set-off, compensation, counterclaim, retention and netting. Notwithstanding the foregoing, if any amounts due and payable to any holder of the Securities by us in respect of, or arising under, the Securities or the Indenture are discharged by set-off, compensation, counterclaim, retention or netting, such holder shall, subject to applicable law, immediately pay to us an amount equal to the amount of such discharge (or, in the event of our winding-up or administration, our liquidator or administrator, as the case may be) and, until such time as payment is made, shall hold an amount equal to such amount in trust for us (or our liquidator or administrator, as the case may be) and, accordingly, any such discharge shall be deemed not to have taken place. By its acquisition of the Securities, each holder agrees to be bound by these provisions relating to waiver of set-off, compensation, counterclaim, retention and netting. No holder of Securities shall be entitled to proceed directly against us except as described in “—Limitation on Suits” below.

Agreement with Respect to the Determination of the Subsequent Interest Rate

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between us and any holder or beneficial owner of the Securities (or the Trustee on behalf of the holders of the Securities), by acquiring the Securities, each holder and beneficial owner of the Securities acknowledges, accepts, agrees to be bound by and consents to the determinations made by the Issuer, the Independent Adviser, the Trustee, the Principal Paying Agent, the Calculation Agent or other relevant entities, as applicable, to determine the Subsequent Interest Rate in the event the Issuer determines that a Benchmark Event has occurred or that there is a Successor Rate, including as may occur without any prior notice from the Issuer and without the need for the Issuer to obtain any further consent from holders and beneficial owners of the Securities to implement consequential amendments to the Indenture and other agreements or documents relating to the Securities. For more information, see “—Determination of Subsequent Interest Rate.”

Agreement with Respect to the Exercise of U.K. Bail-in Power

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between us and any holder or beneficial owner of the Securities (or the Trustee on behalf of the holders of the Securities), by acquiring the Securities, each holder and beneficial owner of the Securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the Relevant U.K. Resolution Authority that may result in (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, the Securities; (ii) the conversion of all, or a portion, of the principal amount of, or interest on, the Securities into shares or other securities or other obligations of the Issuer or another person (and the issue to, or conferral on, the holder or beneficial owner of the Securities, of such shares,

S-69

securities or obligations); (iii) the cancellation of the Securities; and/or (iv) the amendment or alteration of the maturity, if any, of the Securities, or the amendment of the amount of interest due on such Securities, or the dates on which interest becomes payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Securities solely to give effect to the exercise by the Relevant U.K. Resolution Authority of such U.K. Bail-in Power.

No repayment of the principal amount of the Securities or payment of interest on the Securities shall become due and payable after the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority unless such repayment or payment would be permitted to be made by the Issuer under the laws and regulations of the U.K. and the European Union applicable to the Issuer.

Upon the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Securities, the Issuer shall provide a written notice to the Clearing Systems as soon as practicable regarding such exercise of the U.K. Bail-in Power for purposes of notifying holders of the Securities of such occurrence. The Issuer shall also deliver a copy of such notice to the Trustee for information purposes. Any delay or failure by the Issuer in delivering any notice referred to in this paragraph shall not affect the validity and enforceability of the U.K. Bail-in Power.

For more information, see “Description of Contingent Capital Securities—Agreement with Respect to the Exercise of U.K. Bail-in Power” in the accompanying prospectus. See also “Risk Factors—Under the terms of the Securities, you agree to be bound by the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority.”

Payment of Contingent Capital Additional Amounts

The Securities are subject to the provisions set forth in the accompanying prospectus under “Description of Contingent Capital Securities—Payment of Contingent Capital Additional Amounts.”

Redemption

Optional Redemption

We may, at our option, redeem the Securities, in whole but not in part, on (i) any day falling in the period commencing on (and including) June 15, 2030 and ending on (and including) the first Reset Date or (ii) any day falling in the period commencing on (and including) the date that is six months before any subsequent Reset Date and ending on (and including) such Reset Date at 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “—Interest Cancellation” above) to (but excluding) the date fixed for redemption. Any optional redemption will be subject, among other things, to the provisions described under “—Notice of Redemption” and “—Condition to Redemption” below.

Regulatory Event Redemption

If there is a change in the regulatory classification of the Securities that occurs on or after the Issue Date and that does, or would be likely to, result in the whole or any part of the outstanding aggregate principal amount of the Securities at any time being excluded from, or ceasing to count towards, the Group’s Tier 1 Capital (a “Regulatory Event”), we may, at our option, at any time, redeem the Securities, in whole but not in part, at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “—Interest Cancellation” above) to (but excluding) the date fixed for redemption. Any redemption upon the occurrence of a Regulatory Event will be subject, among other things, to the provisions described under “—Notice of Redemption” and “—Condition to Redemption” below.

As a holding company of financial institutions, we are required to hold certain kinds and amounts of capital to help us meet our obligations as they fall due. Under U.K. CRD, this capital includes both “Tier 1 Capital” and

S-70

“Tier 2 Capital,” with Tier 1 Capital divided into “Common Equity Tier 1 Capital” and “Additional Tier 1 Capital.” The Securities are intended to qualify as Additional Tier 1 Capital under the U.K. CRD. Additional Tier 1 Capital under the U.K. CRD consists of (i) perpetual subordinated capital instruments that meet the requirements set out in U.K. CRD to ensure that they are sufficiently loss absorbent on a “going concern” basis (i.e., capital that absorbs losses enabling the relevant credit institution to avoid insolvency) and (ii) the share premium account related to such instruments. Under the U.K. CRD, Tier 2 Capital broadly includes qualifying subordinated debt that provides loss absorption on a “gone concern” basis (i.e., capital that absorbs losses in an insolvency prior to senior creditors suffering any losses). Both Tier 1 Capital and Tier 2 Capital items are subject to deductions that are specific to each type of capital as provided under U.K. CRD. For more information, see “Risk Factors—Risks Relating to the Securities—Changes in law may adversely affect the rights of holders of the Securities.”

Tax Redemption

We may, at our option, redeem the Securities, in whole but not in part, at any time, at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “—Interest Cancellation” above) to (but excluding) the date fixed for redemption, if we determine that as a result of a change in, or amendment to, the laws or regulations of a Taxing Jurisdiction, including any treaty to which the relevant Taxing Jurisdiction is a party, or a change in an official application of those laws or regulations, including a decision of any court or tribunal, which becomes effective on or after the Issue Date (or which becomes effective on or after the date of a successor entity’s assumption of our obligations):

(each such change in tax law or regulation or the official application thereof, a “Tax Event”); provided that, in the case of each Tax Event, the consequences of the Tax Event cannot be avoided by us taking reasonable measures available to us.

Before we give a notice of redemption as a result of a Tax Event, we shall be required to deliver to the Trustee an opinion of independent counsel of recognized standing, chosen by us, confirming that we are entitled to exercise our right of redemption.

Any redemption as a result of a Tax Event will also be subject to the provisions described under “—Notice of Redemption” and “—Condition to Redemption” below.

Clean-Up Call

If, at any time from the fifth anniversary of the Issue Date (unless otherwise permitted by the PRA), the outstanding aggregate principal amount of the Securities is 25% or less of the aggregate principal amount of the

S-71

Securities originally issued (and, for these purposes, any additional securities referred to under “—Further Issues” shall be deemed to have been originally issued), we may redeem all (but not some only) of the outstanding Securities at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described under “—Interest Cancellation” above) to (but excluding) the date fixed for redemption. Any such redemption will be subject, among other things, to the provisions described under “—Notice of Redemption” and “—Condition to Redemption” below.

Notice of Redemption

Any redemption of the Securities shall be subject to our giving not less than fifteen (15) days’, nor more than sixty (60) days’, prior notice to the holders of the Securities through the Clearing Systems (or, if the Securities are held in definitive form, to the holders at their addresses shown on the register for the Securities) (such notice being irrevocable except in the limited circumstances described in the following paragraph) specifying our election to redeem the Securities and the date fixed for such redemption. The Issuer shall not be entitled to deliver a notice of redemption after an Automatic Conversion Notice has been delivered.

If the Issuer has elected to redeem the Securities but the Solvency Condition is not satisfied in respect of the relevant redemption payment on the applicable redemption date, the relevant redemption notice shall be automatically rescinded and shall be of no force and effect and no payment of the redemption amount will be due and payable. The Issuer shall notify the holders and the Trustee of any such rescission as soon as practicable prior to, or, as the case may be, following, the applicable redemption date, provided however that failure to provide such notice will not have any impact on the effectiveness of, or otherwise invalidate, any such rescission. In addition, if the Issuer has elected to redeem the Securities but prior to the payment of the redemption amount with respect to such redemption a Capital Adequacy Trigger Event occurs, the relevant redemption notice shall be automatically rescinded and shall be of no force and effect, no payment of the redemption amount will be due and payable and an Automatic Conversion shall occur as described under “—Automatic Conversion Upon Capital Adequacy Trigger Event” below.

If the Issuer has elected to redeem the Securities but prior to the payment of the redemption amount with respect to such redemption the Relevant U.K. Resolution Authority exercises its U.K. Bail-in Power in respect of the Securities, the relevant redemption notice shall be automatically rescinded and shall be of no force and effect, and no payment of the redemption amount will be due and payable.

Condition to Redemption

Notwithstanding any other provision, we may redeem the Securities (and give notice thereof to the holders of the Securities) only if we have obtained the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations) for the redemption of the Securities. In addition, any redemption of the Securities shall be subject to the additional conditions set out under “Description of Contingent Capital Securities—Additional Conditions Relating to Redemption and Repurchase of Contingent Capital Securities” in the accompanying prospectus.

Condition to Repurchase

The Issuer or any member of the Group may purchase or otherwise acquire any of the outstanding Securities at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations) and to applicable law and regulation. In addition, any such repurchase of outstanding Securities shall be subject to the additional conditions set out under “Description of Contingent Capital Securities—Additional Conditions Relating to Redemption and Repurchase of Contingent Capital Securities” in the accompanying prospectus.

S-72

Substitution or Variation

Following the occurrence of a Tax Event or a Regulatory Event, the Issuer may (without any requirement for the consent or approval of the holders or the Trustee (but subject to the notice requirements described below)) either substitute all (but not some only) of the Securities for, or vary the terms of the Securities so that they remain or, as appropriate, become, Compliant Securities (as defined below). Upon the expiry of the notice requirements described below, the Issuer shall either substitute or vary the terms of the Securities and, subject to the conditions as set out below, the Trustee shall agree to such substitution or variation; provided that such substitution or variation shall not itself give rise to a right of the Issuer to redeem the varied or substituted securities.

Any substitution or variation is subject to the Issuer (i) obtaining the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations) for such substitution or variation of the Securities and (ii) giving not less than 15 nor more than 60 days’ prior notice to the Trustee (with a copy to the Principal Paying Agent) and to the holders of the Securities, which notice shall be irrevocable, except in the limited circumstances described under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Automatic Conversion Procedure^” below.

For the purposes of this section:

“Compliant Securities” means securities issued directly by the Issuer that:

“Rating Agency” means S&P Global Ratings UK Limited, Moody’s Investors Service Limited, Fitch Ratings Ltd or Rating and Investment Information, Inc., or any of their respective affiliates or successors.

Conversion Price

The Conversion Price of the Securities is fixed at £1.65 per Conversion Share, subject to certain anti-dilution adjustments, as described under “—Anti-Dilution” below (the “Conversion Price”).

Automatic Conversion Upon Capital Adequacy Trigger Event

If a Capital Adequacy Trigger Event occurs, then an Automatic Conversion will occur on the Conversion Date, as described under “—Automatic Conversion Procedure” below, at which point all of the Issuer’s obligations under

S-73

the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository on the Conversion Date at the Conversion Price, and under no circumstances shall such released obligations be reinstated. If the Issuer has been unable to appoint a Conversion Shares Depository, it shall make such other arrangements for the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the holders of the Securities as it shall consider reasonable in the circumstances, which may include issuing the Conversion Shares to another nominee or to the holders of the Securities directly, which issuance shall irrevocably and automatically release all of the Issuer’s obligations under the Securities (other than the CSO Obligations, if any) as if the Conversion Shares had been issued to the Conversion Shares Depository.

The Automatic Conversion shall occur without delay upon the occurrence of a Capital Adequacy Trigger Event.

A “Capital Adequacy Trigger Event” shall occur if at any time the fully loaded CET1 Ratio is less than 7.00%. Whether a Capital Adequacy Trigger Event has occurred at any time shall be determined by the Issuer and such determination shall be binding on the Trustee and holders of the Securities.

The Conversion Shares shall initially be registered in the name of the Conversion Shares Depository (which shall hold the Conversion Shares on behalf of the holders of the Securities) or the relevant recipient as contemplated above, and each holder of the Securities shall be deemed to have irrevocably directed the Issuer to issue the Conversion Shares corresponding to the conversion of its holding of Securities to the Conversion Shares Depository (or to such other relevant recipient).

The Issuer shall immediately inform the PRA of the occurrence of a Capital Adequacy Trigger Event and shall deliver an Automatic Conversion Notice to holders of the Securities as described under “—Automatic Conversion Procedure” below.

Following an Automatic Conversion, no holder of the Securities will have any rights against the Issuer with respect to the repayment of the principal amount of the Securities or the payment of interest or any other amounts in respect of or arising under such Securities, which liabilities of the Issuer shall be irrevocably and automatically released and, accordingly, the principal amount of the Securities shall equal zero at all times thereafter. Any interest in respect of an interest period ending on any Interest Payment Date falling between the date of a Capital Adequacy Trigger Event and the Conversion Date shall be deemed to have been cancelled upon the occurrence of such Capital Adequacy Trigger Event and shall not be due and payable.

Provided that the Issuer issues the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient as contemplated above) in accordance with the terms of the Securities as described herein, with effect from the Conversion Date, holders of the Securities shall have recourse only to the Conversion Shares Depository (or to such other relevant recipient, as applicable) for the delivery to them of Conversion Shares or, if the Issuer elects that a Conversion Shares Offer be made as described under “—Conversion Shares Offer” below, of any Conversion Shares Offer Consideration to which such holders are entitled as described herein.

Following the issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient as contemplated above and as applicable) on the Conversion Date, the Securities shall remain in existence until the applicable Cancellation Date for the sole purpose of evidencing (a) the holder’s right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or such other relevant recipient) and (b) the Issuer’s CSO Obligations, if any. The Issuer currently expects that beneficial interests in the Securities will be transferrable until the Suspension Date and that any trades in the Securities would clear and settle through the Clearing Systems until such date. However, there is no guarantee that an active trading market will exist for the Securities following the Automatic Conversion. The Securities will cease to be admitted to trading on the ISM after the Suspension Date, subject to receipt by the ISM of any notice by the Issuer required under the ISM’s rules and operating procedures.

S-74

Subject to the conditions described under “—Settlement Procedure” below, the Conversion Shares or Conversion Share component, if any, of any Conversion Shares Offer Consideration, as applicable, will be delivered to holders of the Securities on the applicable Settlement Date, the cash component, if any, of any Conversion Shares Offer Consideration will be delivered to holders of the Securities on or around the date on which the Conversion Shares Offer Period ends and the Securities shall be cancelled on the applicable Cancellation Date.

The Securities are not convertible into Conversion Shares at the option of the holders at any time.

Notwithstanding any other provision herein, by its subscription, purchase or acquisition of the Securities, each holder shall (i) agree to all the terms of the Securities, including, without limitation, those related to (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic Conversion and (y) the appointment of the Conversion Shares Depository, the issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer, (ii) agree that effective upon, and following, an Automatic Conversion, no amount shall be due and payable to the holders under the Securities and the liability of the Issuer to pay any such amounts (including the principal amount of, or any interest in respect of, the Securities) shall be automatically released, and the holders shall not have the right to give a direction to the Trustee with respect to the Capital Adequacy Trigger Event and any related Automatic Conversion and (iii) waive, to the extent permitted by the Trust Indenture Act, any claim against the Trustee arising out of its acceptance of its trusteeship for the Securities), including, without limitation, claims related to or arising out of or in connection with a Capital Adequacy Trigger Event and/or any Automatic Conversion.

Automatic Conversion Procedure

If a Capital Adequacy Trigger Event has occurred, we shall deliver an Automatic Conversion Notice to the Trustee and to the holders of the Securities through the Clearing Systems as soon as practicable after such time.

The date on which the Automatic Conversion Notice shall be deemed to have been given shall be the date on which it is dispatched by the Issuer to each of the Clearing Systems (or if the Securities are held in definitive form, to the Trustee).

The Automatic Conversion shall occur on the Conversion Date and all of the Issuer’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Issuer’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) and the principal amount of the Securities shall equal zero at all times thereafter (although the Tradable Amount shall remain unchanged) as a result of the Automatic Conversion.

Within ten (10) Business Days following the Conversion Date, the Issuer shall deliver a Conversion Shares Offer Notice to the Trustee directly and to the holders of the Securities through the Clearing Systems.

The Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities, as applicable) shall hold the Conversion Shares on behalf of the holders of the Securities, who shall be entitled to direct (each in respect of their pro rata share of the Conversion Shares) the Conversion Shares Depository or such other recipient, as applicable, to exercise on their behalf all rights of an ordinary shareholder (including voting rights and rights to receive dividends) except that holders shall not be able to sell or otherwise transfer the Conversion Shares until such time as they have been delivered to holders in accordance with the procedures set forth under “—Settlement Procedure” below. A holder’s pro rata share of the Conversion Shares at any particular time shall be determined based on the aggregate amount of the Tradable Amount of the Securities held by such holder as a proportion of the aggregate amount of the Tradable Amount of all Securities outstanding at the relevant time rounded down, if necessary, to the nearest whole number of Conversion Shares.

S-75

Once we have delivered the Automatic Conversion Notice to each of the Clearing Systems following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (a) the holders shall have no rights whatsoever under the Indenture or the Securities to instruct the Trustee to take any action whatsoever and (b) as of the date of the Automatic Conversion Notice, except for any indemnity and/or security provided by any holder in such direction or related to such direction, any direction previously given to the Trustee by any holders shall cease automatically and shall be null and void and of no further effect, except in each case of (a) and (b), with respect to any rights of holders with respect to any payments under the Securities that were unconditionally due and payable prior to the date of the Automatic Conversion Notice (if any) or unless the Trustee is instructed in writing by us to act otherwise.

The procedures set forth in this section are subject to change to reflect changes in clearing system practices.

The Conversion Shares

The number of Conversion Shares to be issued to the Conversion Shares Depository on the Conversion Date shall be determined by the Issuer by dividing the aggregate principal amount of the Securities outstanding immediately prior to the Automatic Conversion on the Conversion Date by the Conversion Price rounded down, if necessary, to the nearest whole number of Conversion Shares. Fractions of Conversion Shares will not be issued following an Automatic Conversion and no cash payment will be made in lieu thereof. Upon Automatic Conversion on the Conversion Date, the number of Conversion Shares to be held by the Conversion Shares Depository for the benefit of each holder shall be the number of Conversion Shares thus calculated multiplied by a fraction equal to the aggregate amount of the Tradable Amount of the book-entry interests in the Securities held by such holder on the Conversion Date divided by the aggregate amount of the Tradable Amount of the book-entry interests of all Securities outstanding immediately prior to the Automatic Conversion on the Conversion Date rounded down, if necessary, to the nearest whole number of Conversion Shares.

The Conversion Shares issued following an Automatic Conversion will be fully paid and non-assessable and will in all respects rank pari passu with our fully paid ordinary shares in issue on the Conversion Date, except in any such case for any right excluded by mandatory provisions of applicable law, and except that the Conversion Shares so issued will not rank for (or, as the case may be, the relevant holder shall not be entitled to receive) any rights, the entitlement to which falls prior to the Conversion Date.

If a Qualifying Takeover Event shall have occurred, then, where the Conversion Date falls on or after the QTE Effective Date, Approved Entity Shares of the Approved Entity shall be issued to the Conversion Shares Depository on the Conversion Date instead of Conversion Shares (see “—Anti-Dilution—Qualifying Takeover Event” below).

The Conversion Shares or the Conversion Shares Offer Consideration, as the case may be, will be delivered to holders of the Securities pursuant to the procedures set forth in “—Settlement Procedure” below.

Conversion Shares Offer

No later than ten (10) Business Days following the Conversion Date, the Issuer may, in its sole and absolute discretion, elect that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Issuer’s ordinary shareholders at such time at a cash price per Conversion Share equal to the Conversion Price, subject as provided below (the “Conversion Shares Offer”). The Issuer may, on behalf of the Conversion Shares Depository, appoint a Conversion Shares Offer Agent to act as placement or other agent to facilitate the Conversion Shares Offer. The Issuer will deliver a Conversion Shares Offer Notice to the Trustee directly and to the holders of the Securities through the Clearing Systems within ten (10) Business Days following the Conversion Date specifying whether or not it has elected that a Conversion Shares Offer be conducted. If so elected, the Conversion Shares Offer Period, during which the Conversion Shares Offer may be made, shall end no later than forty (40) Business Days after the delivery of the Conversion Shares Offer Notice.

S-76

Any Conversion Shares Offer shall be made subject to applicable laws and regulations in effect at the relevant time and shall be conducted, if at all, only to the extent that the Issuer, in its sole and absolute discretion, determines that the Conversion Shares Offer is practicable. The Issuer or the purchasers of the Conversion Shares sold in any Conversion Shares Offer shall bear the costs and expenses of any Conversion Shares Offer (other than the taxes referred to in the definition of Conversion Shares Offer Consideration), including the fees of the Conversion Shares Offer Agent, if any. If a prospectus or other offering document is required to be prepared in connection with a Conversion Shares Offer, the Issuer will facilitate the preparation of such prospectus or other offering document, and the Issuer and/or its directors will take responsibility for such prospectus or other offering document, in each case, if and to the extent then required by applicable laws and regulations then in effect. In addition, if so requested by the Conversion Shares Depository as offeror, the Issuer shall indemnify the Conversion Shares Depository for any losses incurred in connection with any Conversion Shares Offer.

Upon completion of the Conversion Shares Offer, the Issuer or the Conversion Shares Depository will provide notice to the holders of the Securities of the composition of the Conversion Shares Offer Consideration (and of the deductions to the cash component, if any, of the Conversion Shares Offer Consideration (as set out in the definition of Conversion Shares Offer Consideration)) per £1,000 Tradable Amount of the Securities. The Conversion Shares Offer Consideration will be delivered to holders of the Securities pursuant to the procedures set forth under “—Settlement Procedure” below. The Issuer reserves the right, in its sole and absolute discretion, to terminate the Conversion Shares Offer at any time during the Conversion Shares Offer Period by providing at least three (3) Business Days’ notice to the Trustee directly and to holders of the Securities through the Clearing Systems, and, if it does so, the Issuer may, in its sole and absolute discretion, take steps (including changing the Suspension Date) to deliver to holders of the Securities the Conversion Shares at a time that is earlier than the time at which they would have otherwise received the Conversion Shares Offer Consideration had the Conversion Shares Offer been completed.

By its subscription for, purchase or other acquisition of the Securities, each holder of the Securities acknowledges and agrees that if the Issuer elects, in its sole and absolute discretion, that a Conversion Shares Offer be conducted by the Conversion Shares Depository, such holder shall be deemed to have: (i) irrevocably consented to any Conversion Shares Offer and to the Conversion Shares Depository using the Conversion Shares to settle any Conversion Shares Offer in accordance with the terms of the Securities, (ii) consented to the transfer of the beneficial interest it holds in the Conversion Shares to the Conversion Shares Depository in connection with the Conversion Shares Offer in accordance with the terms of the Securities, (iii) irrevocably agreed that the Issuer, the Conversion Shares Depository and the Conversion Shares Offer Agent, if any, may take any and all actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, agreed that none of the Issuer, the Trustee, the Conversion Shares Depository, if any, or the Conversion Shares Offer Agent, if any, shall, to the extent permitted by applicable law, incur any liability to the holders in respect of the Conversion Shares Offer (except for the obligations of the Conversion Shares Depository in respect of the holders’ entitlement to any Conversion Shares Offer Consideration) and (iv) authorized, directed and requested each of the Clearing Systems and their respective direct or indirect participants or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the Automatic Conversion (including any related Conversion Shares Offer).

The Conversion Shares Offer may be conducted at the election of the Issuer, in its sole and absolute discretion, on the terms described above. The Issuer currently expects that in determining whether or not a Conversion Shares Offer shall be conducted and, if one is to be conducted, how and to whom such Conversion Shares Offer shall be made, the directors of the Issuer would, in accordance with their duties, have regard to a variety of matters, including, without limitation, the interests of the Issuer’s shareholders, taken as a whole, and the potential impact of a Conversion Shares Offer on the Issuer’s financial stability.

Further, neither the occurrence of a Capital Adequacy Trigger Event nor, following the occurrence of a Capital Adequacy Trigger Event, the election (if any) by the Issuer to undertake a Conversion Shares Offer on the terms set out herein, shall preclude the Issuer from undertaking a rights issue at any time on such terms as the

S-77

Issuer deems appropriate, at its sole discretion, including—for the avoidance of doubt—the offer of ordinary shares at or below the Conversion Price. Moreover, there can be no assurance that the Conversion Shares Offer would be conducted pursuant to registration under the Securities Act.

Settlement Procedure

Delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the holders of the Securities will be made in accordance with the following procedures. The procedures set forth in this section are subject to change to reflect changes in clearing system practices.

It is expected that the Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration) will be delivered to holders of the Securities in uncertificated form through the dematerialized securities trading system operated by Euroclear UK & International Limited, known as CREST, unless the Conversion Shares are not a participating security in CREST at the relevant time, in which case the Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration) will either be delivered in the form of the relevant clearing system in which the Conversion Shares are a participating security or in certificated form, as notified by the Issuer to the holders of the Securities through the Clearing Systems (or, if the Securities are held in definitive form, to the Trustee directly and to the holders at their addresses shown on the register for the Securities). It is expected that where the Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration) are to be delivered through CREST or such other clearing system in which such Conversion Shares are a participating security, they will be delivered to the account specified by the relevant holder in the relevant Conversion Shares Settlement Notice as described below. It is expected that where the Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration) are to be delivered in certificated form, the name of the relevant holder (or its nominee) will be entered in the Issuer’s share register and a certificate in respect thereof will be dispatched by mail free of charge to the relevant holder or as it may direct in the relevant Conversion Shares Settlement Notice as described below. It is expected that the cash component, if any, of any Conversion Shares Offer Consideration will be delivered through the facilities of the Clearing Systems (or, if the Securities are held in definitive form, by check mailed to the holders at their address shown on the register for the Securities) on or around the date on which the Conversion Shares Offer Period ends, subject to the respective procedures of each of the Clearing Systems in effect at such time. If it is not expected that the cash component, if any, of any Conversion Shares Offer Consideration will be delivered through the Clearing Systems, such cash component will be delivered by transfer on or around the date on which the Conversion Shares Offer Period ends to such sterling account maintained by the payee with a bank in London as the holder of the Securities may direct in the Conversion Shares Settlement Notice, provided that such notice is delivered to the Conversion Shares Depository before the end of the Conversion Shares Offer Period.

The Conversion Shares Offer Notice shall specify the Suspension Date. On the Suspension Date, the Issuer shall deliver a Conversion Shares Settlement Request Notice to the Trustee directly and to the holders of the Securities through the Clearing Systems. Such notice shall request that holders complete a Conversion Shares Settlement Notice and shall specify the Notice Cut-off Date and the Final Cancellation Date.

On the Suspension Date, each of the Clearing Systems shall suspend all clearance and settlement of transactions in the Securities. As a result, holders of the Securities will not be able to settle the transfer of any Securities following the Suspension Date, and any sale or other transfer of the Securities that a holder of the Securities may have initiated prior to the Suspension Date that is scheduled to settle after the Suspension Date will be rejected by the Clearing Systems and will not be settled through the Clearing Systems.

The Securities will cease to be admitted to trading on the ISM after the Suspension Date, subject to receipt by the ISM of any notice by the Issuer required under the ISM’s rules and operating procedures.

In order to obtain delivery of the relevant Conversion Shares or Conversion Share component, if any, of any Conversion Shares Offer Consideration, as applicable, a holder must deliver its Conversion Shares Settlement

S-78

Notice to the Conversion Shares Depository on or before the Notice Cut-off Date. If such delivery is made after the end of normal business hours at the specified office of the Conversion Shares Depository, such delivery shall be deemed for all purposes to have been made or given on the next following Business Day.

If the Securities are held through the Clearing Systems, the Conversion Shares Settlement Notice must be given in accordance with the standard procedures of the Clearing Systems (which may include the notice being given to the Conversion Shares Depository by electronic means) and in a form acceptable to the Clearing Systems and the Conversion Shares Depository. If the Securities are in definitive form, the Conversion Shares Settlement Notice must be delivered to the specified office of the Conversion Shares Depository together with the relevant Securities.

Subject as provided herein and provided the Conversion Shares Settlement Notice and the relevant Securities, if applicable, are delivered on or before the Notice Cut-off Date, the Conversion Shares Depository shall deliver the relevant Conversion Shares (rounded down to the nearest whole number of Conversion Shares) or Conversion Share component, if any, of any Conversion Shares Offer Consideration (rounded down to the nearest whole number of Conversion Shares), as applicable, to the holder of the relevant Securities completing the relevant Conversion Shares Settlement Notice or its nominee in accordance with the instructions given in such Conversion Shares Settlement Notice on the applicable Settlement Date.

Each Conversion Shares Settlement Notice shall be irrevocable. Failure to properly complete and deliver a Conversion Shares Settlement Notice and the relevant Securities, if applicable, may result in such notice being treated by the Conversion Shares Depository as null and void. Any determination as to whether any Conversion Shares Settlement Notice has been properly completed and delivered shall be made by the Conversion Shares Depository in its sole and absolute discretion and shall be conclusive and binding on the relevant holder.

Neither the Issuer, nor any member of the Group shall be liable for any stamp duty, stamp duty reserve tax, or any other capital, issue, transfer, registration, financial transaction or documentary tax that may arise or be paid as a consequence of the delivery of Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration), which tax shall be borne solely by the holder or, if different, the person to whom the Conversion Shares (or the Conversion Share component, if any, of any Conversion Shares Offer Consideration) are delivered.

The Conversion Shares (and the Conversion Share component, if any, of any Conversion Shares Offer Consideration) will not be available for delivery (i) to, or to a nominee for, Euroclear or Clearstream, Luxembourg or any other person providing a clearance service within the meaning of Section 96 of the Finance Act 1986 of the U.K. or (ii) to a person, or nominee or agent for a person, whose business is or includes issuing depository receipts within the meaning of Section 93 of the Finance Act 1986 of the U.K., in each case at any time prior to the “abolition day” as defined in Section 111(1) of the Finance Act 1990 of the U.K., or, if earlier, such other time at which the Issuer, in its absolute discretion, determines that no charge under Section 67, 70, 93 or 96 of the Finance Act 1986 or any similar charge (under any successor legislation) would arise as a result of such delivery or (iii) to the CREST account of such a person described in (i) or (ii).

Failure to Deliver a Conversion Shares Settlement Notice

If a Conversion Shares Settlement Notice and the relevant Securities, if applicable, are not delivered to the Conversion Shares Depository on or before the Notice Cut-off Date, then the Conversion Shares Depository shall continue to hold the relevant Conversion Shares (or Conversion Share component, if any, of any Conversion Shares Offer Consideration) until a Conversion Shares Settlement Notice (and the relevant Securities, if applicable) is so delivered. However, the relevant Securities shall be cancelled on the Final Cancellation Date and any holder of Securities delivering a Conversion Shares Settlement Notice after the Notice Cut-off Date will have to provide evidence of its entitlement to the relevant Conversion Shares (or the relevant Conversion Shares component, if any, of any Conversion Shares Offer Consideration) satisfactory to the Conversion Shares

S-79

Depository in its sole and absolute discretion in order to receive delivery of such Conversion Shares (or Conversion Share component of any Conversion Shares Offer Consideration). The Issuer shall have no liability to any holder of the Securities for any loss resulting from such holder not receiving any Conversion Shares (or Conversion Share component of any Conversion Shares Offer Consideration) or from any delay in the receipt thereof, in each case as a result of such holder failing to duly submit a Conversion Shares Settlement Notice and the relevant Securities, if applicable, on a timely basis or at all.

Adjustment of Conversion Price

Upon the occurrence of any of the events described below, the Conversion Price shall be adjusted as follows:

where:

Such adjustment shall become effective on the date the consolidation, reclassification or subdivision, as the case may be, takes effect.

S-82

A

B

where:

Such adjustment shall become effective on the date of issue of such ordinary shares.

where:

Such adjustment shall become effective on the Effective Date.

For the purpose of any calculation of the consideration receivable or price pursuant to this paragraph (iii), the following provisions shall apply:

S-83

A – B

A

where:

Such adjustment shall become effective on the Effective Date.

Notwithstanding the foregoing provisions:

No Retroactive Adjustments

The Issuer shall not issue any additional Conversion Shares if the Automatic Conversion occurs after the record date in respect of any consolidation, reclassification or subdivision as is mentioned in paragraph (i) of “—Adjustment of Conversion Price” above, or after the record date or other due date for the establishment of

S-84

entitlement for any such issue, distribution, grant or offer (as the case may be) as is mentioned in paragraphs (ii), (iii) or (iv) of “—Adjustment of Conversion Price” above, but before the relevant adjustment to the Conversion Price becomes effective under such section.

Decision of an Independent Financial Adviser

If any doubt shall arise as to whether an adjustment is required to be made to the Conversion Price or as to the appropriate adjustment to such Conversion Price, and following consultation between the Issuer and an Independent Financial Adviser, a written opinion of such Independent Financial Adviser in respect thereof shall be conclusive and binding on the Issuer, the Trustee and the holders of the Securities, save in the case of manifest error.

Rounding Down and Notice of Adjustment to the Conversion Price

On any adjustment to the Conversion Price as provided under “—Anti-Dilution”, if the resultant Conversion Price is a number with more decimal places than the initial Conversion Price, that number shall be rounded to the same number of decimal places as the initial Conversion Price. No adjustment shall be made to the Conversion Price where such adjustment (rounded down if applicable) would be less than 1% of the Conversion Price then in effect. Any adjustment not required to be made, and/or any amount by which the Conversion Price has been rounded down, shall be carried forward and taken into account in any subsequent adjustment, and such subsequent adjustment shall be made on the basis that the adjustment not required to be made had been made at the relevant time and/or, as the case may be, that the relevant rounding down had not been made.

Notice of any adjustments to the Conversion Price shall be given by the Issuer to holders of the Securities via each Clearing System (or, if the Securities are held in definitive form, through the Trustee) promptly after the determination thereof.

The Conversion Price shall not in any event be reduced to below the nominal value of the ordinary shares.

Qualifying Takeover Event

S-85

The Trustee shall be obliged (at the expense of the Issuer) to concur with the Issuer in making any such amendments and modifications to the Indenture, and to execute any supplemental indentures to the Indenture in respect thereof, provided that the Trustee shall not be bound to do so if any such amendments or modifications would, in the opinion of the Trustee, have the effect of (i) exposing the Trustee to any liability against which it is not indemnified and/or secured and/or pre-funded to its satisfaction, (ii) changing, increasing or adding to the obligations or duties of the Trustee or (iii) removing or amending any protection or indemnity afforded to, or any other provision in favor of, the Trustee under the Indenture and/or the terms of the Securities.

For the avoidance of doubt, if a Takeover Event is not a Qualifying Takeover Event (including if that is because the Acquirer is a Governmental Entity), there is no provision for any automatic adjustment to the terms of the Securities, whether in the manner provided for above in respect of Qualifying Takeover Events, or at all, and therefore the provisions above under “—Automatic Conversion Upon Capital Adequacy Trigger Event” shall continue to apply and “Conversion Shares” will continue to have the meaning set out in “—Automatic Conversion Upon Capital Adequacy Trigger Event —Definitions.”

Such shares shall cease to be “Approved Entity Shares” if they do not satisfy the definition above on the Conversion Date. In relation to an Automatic Conversion in respect of which the Conversion Date falls on or after the QTE Effective Date, references herein to “Conversion Shares” shall be deemed to be references to “Approved Entity Shares.”

and provided further that, if on each of the said five dealing days the Volume Weighted Average Price shall have been based on a price cum-Cash Dividend (or cum- any other entitlement) in respect of a Cash Dividend (or other entitlement) which has been declared or announced but the ordinary shares to be issued do not rank for that Cash Dividend (or other entitlement), the Volume Weighted Average Price on each of such dates shall, for the purposes of this definition, be deemed to be the amount thereof reduced by an amount equal to such Cash Dividend or entitlement per ordinary share as at the date of first public announcement relating to such Cash Dividend or entitlement, in any such case, determined on a gross basis and disregarding any withholding or deduction required to be made on account of tax, and disregarding any associated tax credit, and provided further that, if the Volume Weighted Average Price of an ordinary share is not available on one or more of the said five dealing days (disregarding for this purpose the proviso to the definition of Volume Weighted Average Price), then the average of such Volume Weighted Average Prices which are available in that five-dealing-day period shall be used (subject to a minimum of two such prices) and if only one, or no, such Volume Weighted Average Price is available in the relevant period, the Current Market Price shall be determined in good faith by an Independent Financial Adviser.

“dealing day” means a day on which the Relevant Stock Exchange or relevant stock exchange or securities market is open for business and on which ordinary shares may be dealt in (other than a day on which the Relevant Stock Exchange or relevant stock exchange or securities market is scheduled to or does close prior to its regular weekday closing time).

If the Issuer is then organized in another jurisdiction, the references to “U.K. Government” shall be read as references to the government of such other jurisdiction.

“Independent Financial Adviser” means an independent financial institution of international repute appointed by the Issuer at its own expense.

The “New Conversion Condition” shall be satisfied if (a) by not later than seven (7) Business Days following the completion of a Takeover Event where the Acquirer is an Approved Entity, there shall be arrangements in place for the Approved Entity to provide for issuance of Approved Entity Shares following an Automatic Conversion of the Securities on terms mutatis mutandis identical to the provisions under “—Automatic Conversion Upon Capital Adequacy Trigger Event” above and (b) the Issuer, in its sole and absolute discretion has determined that such arrangements are in the best interest of the Issuer and its shareholders taken as a whole having regard to the interests of its stakeholders (including, but not limited to, the holders of the Securities) and are consistent with applicable law and regulation (including, but not limited to, the guidance of any applicable regulatory body).

“Takeover Event Notice” means the notice to the holders of the Securities notifying them that a Takeover Event has occurred and specifying: (1) the identity of the Acquirer; (2) whether the Takeover Event is a Qualifying Takeover Event or not; (3) in the case of a Qualifying Takeover Event, if determined at such time, the New Conversion Price; and (4) if applicable, the QTE Effective Date.

“Taxes” has the meaning given to such term in the accompanying prospectus.

“Taxing Jurisdiction” has the meaning given to such term in the accompanying prospectus.

“Volume Weighted Average Price” means, in respect of an ordinary share (or an Approved Entity Share, as applicable) on any dealing day, the order book volume-weighted average price of an ordinary share (or Approved Entity Share, as applicable) published by or derived from the relevant Bloomberg page or such other source as shall be determined in good faith to be appropriate by an Independent Financial Adviser on such dealing day, provided that if on any such dealing day such price is not available or cannot otherwise be determined as

S-89

provided above, the Volume Weighted Average Price of an ordinary share (or an Approved Entity Share, as applicable) in respect of such dealing day shall be the Volume Weighted Average Price, determined as provided above, on the immediately preceding dealing day on which the same can be so determined or determined as an Independent Financial Adviser might otherwise determine in good faith to be appropriate.

References to “ordinary share capital” has the meaning provided in Section 1119 of the U.K. Corporation Tax Act 2010 (or successor provision or legislation) and “equity share capital” has the meaning provided in Section 548 of the Companies Act.

References to any act or statute or any provision of any act or statute shall be deemed also to refer to any statutory modification or re-enactment thereof or any statutory instrument, order or regulation made thereunder or under such modification or re-enactment.

References to any issue or offer or grant to shareholders “as a class” or “by way of rights” shall be taken to be references to an issue or offer or grant to all or substantially all shareholders, as the case may be, other than shareholders, as the case may be, to whom, by reason of the laws of any territory or requirements of any recognized regulatory body or any other stock exchange or securities market in any territory or in connection with fractional entitlements, it is determined not to make such issue or offer or grant.

Enforcement Events and Remedies

Winding-up

If a Winding-up Event occurs before the occurrence of a Capital Adequacy Trigger Event, subject to “—Ranking” above, the outstanding principal amount of the Securities will become immediately due and payable.

For the avoidance of doubt, as the principal amount of the Securities will become immediately due and payable upon a Winding-up Event that occurs before the occurrence of a Capital Adequacy Trigger Event, neither the Trustee nor the holders of the Securities are required to declare such principal amount to be due and payable.

A “Winding-up Event” with respect to the Securities shall result if (i) a court of competent jurisdiction in England (or such other jurisdiction in which we may be organized) makes an order for our winding-up which is not successfully appealed within thirty (30) days of the making of such order, (ii) our shareholders adopt an effective resolution for our winding-up (other than, in the case of either (i) or (ii) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (iii) following the appointment of an administrator of the Issuer, the administrator gives notice that it intends to declare and distribute a dividend.

Non-payment

If we fail to pay any amount that has become due and payable under the Securities and such failure continues for fourteen (14) days, the Trustee may give us written notice of such failure. If within a period of fourteen (14) days following the provision of such notice, the failure continues and has not been cured nor waived (a “Non-Payment Event”), the Trustee may, at its discretion and without further notice to us, institute proceedings in England (or such other jurisdiction in which we may be organized) (but not elsewhere) for our winding-up and/or prove in our winding-up and/or claim in our liquidation or administration. For the avoidance of doubt, no interest will be due and payable if such interest has been cancelled or is deemed cancelled (in each case, in whole or in part) as described under “—Interest Cancellation” above. Accordingly, no default in payment under the Securities will have occurred or be deemed to have occurred in such circumstances.

S-90

Limited remedies for breach of obligations (other than non-payment)

In addition to the remedies for non-payment provided above, the Trustee may without further notice institute such proceedings against the Issuer as the Trustee may deem fit to enforce any term, obligation or condition binding on us under the Securities or the Indenture (other than any payment obligation of the Issuer under or arising from the Securities or the Indenture, including, without limitation, payment of any principal or interest, including Contingent Capital Additional Amounts) (such obligation, a “Performance Obligation”); provided always that the Trustee (acting on behalf of the holders of the Securities) and the holders of the Securities may not enforce, and may not be entitled to enforce or otherwise claim, against the Issuer any judgment or other award given in such proceedings that requires the payment of money by the Issuer, whether by way of damages or otherwise (a “Monetary Judgment”), except by proving such Monetary Judgment in a winding-up of the Issuer and/or by claiming such Monetary Judgment in an administration of the Issuer. By its acquisition of the Securities, each holder of the Securities acknowledges and agrees that such holder will not seek to enforce or otherwise claim, and will not direct the Trustee (acting on behalf of the holders of the Securities) to enforce or otherwise claim, a Monetary Judgment against the Issuer in connection with the Issuer’s breach of a Performance Obligation, except by proving such Monetary Judgment in a winding-up of the Issuer and/or by claiming such Monetary Judgment in an administration of the Issuer. See “Risk Factors—Risks Relating to the Securities—Holders of the Securities will have limited remedies.”

No other remedies

Other than the limited remedies specified herein under “Enforcement Events and Remedies” above and subject to “—Trust Indenture Act remedies” below, no remedy against us will be available to the Trustee (acting on behalf of the holders of the Securities) or the holders of the Securities whether for the recovery of amounts owing in respect of the Securities or under the Indenture or in respect of any breach by us of any of our obligations under or in respect of the terms of such Securities or under the Indenture in relation thereto; provided, however, that such limitation shall not apply to our obligations to pay the fees and expenses of, and to indemnify, the Trustee (including fees and expenses of Trustee’s counsel) and the Trustee’s rights to apply money collected to first pay its fees and expenses shall not be subject to the subordination provisions set forth in the Indenture.

Trust Indenture Act remedies

Notwithstanding the limitation on remedies specified herein under “Enforcement Events and Remedies” above, (1) the Trustee will have such powers as are required to be authorized to it under the Trust Indenture Act in respect of the rights of the holders of the Securities under the provisions of the Indenture and (2) nothing shall impair the right of a holder of the Securities under the Trust Indenture Act, absent such holder’s consent, to sue for any payment due but unpaid with respect to the Securities; provided that, in the case of each of (1) and (2) above, any payments in respect of, or arising from, the Securities, including any payments or amounts resulting or arising from the enforcement of any rights under the Trust Indenture Act in respect of the Securities, are subject to the subordination provisions set forth in the Indenture. No holder of Securities shall be entitled to proceed directly against us except as described herein in “—Limitation on Suits” below.

An Automatic Conversion will not constitute a default under the Indenture.

Trustee’s Duties

In case of a default under the Securities, the Trustee shall exercise such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. For these purposes, a “default” shall occur (i) upon a Winding-Up Event that occurs before the occurrence of a Capital Adequacy Trigger Event, (ii) upon the occurrence of a Non-Payment Event or (iii) upon a breach by the Issuer of a Performance Obligation (as described under “Enforcement Events and Remedies—Limited remedies for breach of obligations (other than

S-91

non-payment)”). Holders of a majority of the aggregate principal amount of the outstanding Securities may not waive any past default specified in clauses (i) and (ii) in the preceding sentence.

If a default occurs and is continuing with respect to the Securities, the Trustee will have no obligation to take any action at the direction of any holders of the Securities, unless they have offered the Trustee security or indemnity satisfactory to the Trustee in its sole discretion. The holders of a majority in aggregate principal amount of the outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding in the name of and on the behalf of the Trustee for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities. However, this direction (a) must not be in conflict with any rule of law or the Indenture and (b) must not be unjustly prejudicial to the holder(s) of the Securities not taking part in the direction, in the case of either (a) or (b) as determined by the Trustee in its sole discretion. The Trustee may also take any other action, consistent with the direction, that it deems proper.

Limitation on Suits

Before a holder of the Securities may bypass the Trustee and bring its own lawsuit or other formal legal action or take other steps to enforce its rights or protect its interests relating to the Securities, the following must occur:

Notwithstanding any contrary provisions, nothing shall impair the right of a holder of the Securities under the Trust Indenture Act, absent such holder’s consent, to sue for any payments due but unpaid with respect to the Securities.

Trustee; Direction of Trustee

The Trustee under the Indenture is The Bank of New York Mellon, London Branch (which is referred to as The Bank of New York Mellon acting through its London Branch in the accompanying prospectus).

The Trustee makes no representation, and shall not be liable with respect to, the information set forth in this prospectus supplement.

Subsequent Holders’ Agreement

Holders of the Securities that acquire the Securities in the secondary market shall be deemed to acknowledge, agree to be bound by and consent to the same provisions specified herein to the same extent as the holders of the Securities that acquire the Securities upon their initial issuance, including, without limitation, with respect to the acknowledgement and agreement to be bound by and consent to the terms of the Securities, including in relation to interest cancellation, the Automatic Conversion, the Conversion Shares Offer, the U.K. Bail-in Power (as defined in the accompanying prospectus), the subordination provisions described under

S-92

“—Ranking”, the waiver of set-off provisions described under “—No Set-off” above and the limitations on remedies specified in “Description of Convertible Securities—Enforcement Events and Remedies—Limited remedies for breach of obligations (other than non-payment)” in the accompanying prospectus.

Calculation Agent

The Calculation Agent is The Bank of New York Mellon, London Branch, or its successor appointed by the Issuer. All determinations and any calculations made by the Calculation Agent for the purposes of calculating the applicable Subsequent Interest Rate (or component thereof) shall be conclusive and binding on the holders of the Securities, the Issuer and the Trustee, absent manifest error. None of the Issuer, the Calculation Agent, the Trustee nor any paying agent shall be responsible for determining whether manifest error has occurred or any liability therefor. The Calculation Agent shall not be responsible to the Issuer, holders of the Securities or any third party for any failure of the Reference Banks to provide quotations as requested of them or as a result of the Calculation Agent having acted on any quotation or other information given by any Reference Banks which subsequently may be found to be incorrect or inaccurate in any way.

TAX CONSIDERATIONS

U.S. Federal Income Tax Consequences

The material U.S. federal income tax consequences of your investment in the Securities and Conversion Shares are summarized below. This section applies to you only if you are a U.S. holder (as defined herein) and you hold your Securities or Conversion Shares as capital assets for tax purposes.

This section does not discuss the tax consequences of members of special classes of holders subject to special rules, including (i) dealers in securities, (ii) traders in securities that elect to use a mark-to-market method of accounting for securities holdings, (iii) tax-exempt organizations, (iv) life insurance companies, (v) holders liable for alternative minimum tax, (vi) holders that actually or constructively own 10 percent or more, of the combined voting power of our voting stock or of the total value of our stock, (vii) holders that hold Securities or Conversion Shares as part of a straddle or a hedging or conversion transaction, (viii) holders that purchase or sell Securities or Conversion Shares as part of a wash sale, (ix) holders whose functional currency is not the U.S. dollar, (x) entities or arrangements that are treated as partnerships for U.S. federal income tax purposes (or partners therein), or (xi) holders who are resident, or (in the case of individuals) ordinarily resident, or who are carrying on a trade, in the U.K. Additionally, this summary only addresses U.S. federal income tax consequences, and does not address consequences arising under state, local, or non-U.S. taxes, U.S. federal estate or gift taxes or the Medicare contribution tax applicable to net investment income of certain non-corporate U.S. holders.

This section is also based on the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations, published rulings and court decisions, and on the Double Taxation Convention between the U.K. and the U.S. as entered into force in March 2003 (the “Treaty”). These laws are subject to change, possibly on a retroactive basis.

A “U.S. holder” is a beneficial owner of Securities or Conversion Shares that is, for U.S. federal income tax purposes, (i) a citizen or resident of the United States, (ii) a U.S. domestic corporation, (iii) an estate whose income is subject to U.S. federal income tax regardless of its source, or (iv) a trust if a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust.

WE URGE YOU TO CONSULT YOUR TAX ADVISER AS TO THE TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF SECURITIES AND CONVERSION SHARES DESCRIBED BELOW AND AS TO THE APPLICATION OF STATE, LOCAL, OR OTHER TAX LAWS TO YOUR INVESTMENT IN YOUR SECURITIES AND CONVERSION SHARES.

Tax Characterization and Distributions on the Securities and Conversion Shares. The Securities and Conversion Shares will be treated as equity for U.S. federal income tax purposes. Accordingly, in general, the interest payments with respect to the Securities and distributions with respect to Conversion Shares will be treated as dividends to the extent of the Issuer’s current or accumulated earnings and profits as determined for U.S. federal income tax purposes. Subject to the discussion under “—PFIC Considerations” below, any portion of such a payment in excess of the Issuer’s current and accumulated earnings and profits would be treated first as a nontaxable return of capital that would reduce your tax basis in the Securities or Conversion Shares, as applicable, and would thereafter be treated as capital gain, the tax treatment of which is discussed below under “—Sale or Redemption of the Securities and Conversion Shares or Cancellation of the Securities pursuant to the U.K. Bail-in Power.” Because the Issuer does not currently maintain calculations of its earnings and profits under U.S. federal income tax principles, it is expected that all interest payments on the Securities and distributions on the Conversion Shares will generally be reported to U.S. holders as dividends.

Subject to the discussion under “—PFIC Considerations” below, interest payments we make with respect to the Securities and distributions with respect to the Conversion Shares that are treated as dividends for U.S.

S-94

federal income tax purposes generally will be qualified dividend income taxable to you at the preferential rates applicable to long-term capital gains, provided that you are treated as holding the Securities and/or Conversion Shares for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date, which is generally the relevant record date in respect of the applicable Interest Payment Date or distribution date (or, if the interest on the Securities or distributions with respect to the Conversion Shares is attributable to a period or periods aggregating over 366 days, provided that you are treated as holding the Securities or the Conversion Shares for more than 90 days during the 181-day period beginning 90 days before such date) and meet other holding period requirements. Amounts we pay with respect to the Securities and with respect to the Conversion Shares will not be eligible for the dividends received deduction generally allowed to U.S. corporations.

Interest payments or distributions with respect to the Conversion Shares generally will be includible in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day you receive such amounts. Any gain or loss you recognize on a subsequent sale, conversion or other disposition of such non-U.S. currency generally will be treated as ordinary income or loss and generally will be income or loss from sources within the United States.

The amount of income you will receive as a result of an interest payment on the Securities and distributions on the Conversion Shares will include amounts, if any, withheld in respect of U.K. taxes. For more information on U.K. withholding taxes, please see the discussion under “—United Kingdom Taxation” in this prospectus supplement. Subject to complex limitations and conditions, some of which may vary depending upon your circumstances, U.K. income taxes withheld from interest payments on the Securities and distributions on Conversion Shares to a U.S. holder not eligible for an exemption from U.K. withholding tax (under the Treaty or otherwise) may be creditable against the U.S. holder’s U.S. federal income tax liability. These generally applicable limitations and conditions include new requirements adopted by the IRS in regulations promulgated in December 2021, and any U.K. tax will need to satisfy these requirements in order to be eligible to be a creditable tax for a U.S. holder. In the case of a U.S. holder that consistently elects to apply a modified version of the foreign tax credit rules under recently issued temporary guidance, and complies with specific requirements set forth in such guidance, the U.K. tax on interest payments on the Securities and distributions on the Conversion Shares generally will be treated as meeting the new requirements and therefore as a creditable tax. In all other cases, the application of these requirements to the U.K. tax on the Securities and distributions on Conversion Shares is uncertain and we have not determined whether these requirements have been met. If the U.K. tax on the Securities and distributions on Conversion Shares is not a creditable tax for a U.S. holder or the U.S. holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued within the same taxable year, the U.S. holder may be able to deduct the U.K. tax on the Securities and distributions on Conversion Shares in computing such U.S. holder’s taxable income for U.S. federal income tax purposes. Amounts we pay with respect to the Securities and Conversion Shares will be considered foreign source income to U.S. holders, and for U.S. holders that elect to claim foreign tax credits, will generally constitute “passive” income for foreign tax credit purposes. The availability and calculation of foreign tax credits and deductions for foreign taxes depend on a U.S. holder’s particular circumstances and involve the application of complex rules to those circumstances. The temporary guidance discussed above also indicates that the Treasury and the IRS are considering proposing amendments to the December 2021 regulations and that the temporary guidance can be relied upon until additional guidance is issued that withdraws or modifies the temporary guidance. U.S. holders should consult their own tax advisers regarding the application of these rules to their particular situations.

Automatic Conversion of the Securities into Conversion Shares. Subject to the discussion under “—PFIC Considerations” below, a U.S. holder generally will not recognize any gain or loss in respect of the receipt of the Conversion Shares following an Automatic Conversion. Your tax basis of the Conversion Shares received will equal the tax basis of the Securities converted and the holding period of such Conversion Shares will generally include the period during which the Securities were held prior to such Automatic Conversion. In general, your tax basis in your Securities will be equal to the U.S. dollar value of the price you paid for them. Where different blocks of Securities were acquired at different times or at different prices, the tax basis and holding period of the Conversion Shares may be determined by reference to each such block of Securities. The tax basis of any

S-95

Conversion Shares received as a taxable adjustment of the Conversion Price, as described below, should be equal to the amount included in income as a constructive distribution, as a result of such adjustment, and the holding period of such stock will commence on the date following such constructive distribution.

Conversion of the Securities into Approved Entity Shares. A conversion or exchange of Securities into Approved Entity Shares after a Qualifying Takeover Event may be a taxable event for U.S. holders, depending upon the circumstances. If treated as a taxable event, you will recognize gain or loss equal to the difference between the fair market value of the Approved Entity Shares you receive upon the conversion or exchange and your tax basis in the Securities. If not treated as a taxable event, the consequences to a U.S. holder with respect to the receipt of Approved Entity Shares after a Qualifying Takeover Event should be the same as described above in “—Automatic Conversion of the Securities into Conversion Shares,” with respect to the receipt of Conversion Shares following an Automatic Conversion.

Sale or Redemption of the Securities and Conversion Shares or Cancellation of the Securities pursuant to the U.K. Bail-in Power. Subject to the discussion under “—PFIC Considerations” below, you will generally recognize capital gain or loss upon the sale or redemption of your Securities (other than a conversion of the Securities into Conversion Shares, as discussed above) or upon the sale of your Conversion Shares in an amount equal to the difference between the amount you receive at such time and your tax basis in the Securities or Conversion Shares (as described above), in each case as determined in U.S. dollars. Additionally, you will generally recognize a capital loss on the complete cancellation of the Securities pursuant to the U.K. Bail-in Power in an amount equal to your tax basis in the Securities. Such capital gain or loss will be long-term capital gain or loss if you held your Securities and Conversion Shares for more than one year. Long-term capital gain of a non-corporate U.S. holder is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations. Such gain or loss will generally be gain or loss from sources within the United States for foreign tax credit purposes. U.S. holders that continue to hold equity of the Issuer following a redemption of their Securities may be subject to Section 302 of the Code, which could cause the redemption proceeds to be treated as dividend income, and treated as described in “—Tax Characterization and Distributions on the Securities and Conversion Shares” above. Redemption proceeds received by a U.S. holder that does not own (and is not deemed to own) a substantial portion of the voting shares of the Issuer, or whose proportionate ownership (including deemed ownership) of such shares does not increase as a result of the redemption or a related transaction, however, are likely to be treated as “not essentially equivalent to a dividend” under Section 302. This summary does not discuss the tax consequences to a U.S. Holder of the receipt of Conversion Shares Offer Consideration that is a combination of cash and Conversion Shares or of a partial cancellation of the Securities pursuant to the U.K. Bail-in Power. U.S. Holders should consult their own tax advisers regarding the treatment of the receipt of Conversion Shares Offer Consideration as well as how to account for proceeds received on the sale or redemption of Securities or Conversion Shares that are not paid in U.S. dollars.

Adjustment of the Conversion Price. The Conversion Price is subject to adjustment under certain circumstances. U.S. Treasury Regulations promulgated under Section 305 of the Code may treat a U.S. holder of the Securities as having received a constructive distribution if and to the extent that certain adjustments (or, in some cases, certain failures to make adjustments) to the fixed conversion rates increase a U.S. holder’s proportionate interest in our assets or earnings.

Adjustments to the Conversion Price made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the U.S. holder of the Securities, however, will generally not be considered to result in a constructive distribution to the U.S. holder. If adjustments that do not qualify as being pursuant to a bona fide reasonable adjustment formula are made (or, in some cases, adjustments that do so qualify that fail to be made), U.S. holders of Securities may be treated as having received a distribution even though they have not received any cash or property. For example, the IRS could assert that decreases in the Conversion Price to reflect an Extraordinary Dividend to holders of ordinary shares will generally give rise to a constructive taxable distribution to the U.S. holders of the Securities. Any constructive distribution would be includable in such U.S. holder’s income at its then fair market value in a manner described above under

S-96

“—Tax Characterization and Distributions on the Securities and Conversion Shares.” Although the Issuer does not believe that an adjustment in most cases is likely to be treated as giving rise to a taxable distribution, it is possible that the IRS, and, if challenged, a court, could disagree with the Issuer’s position.

PFIC Considerations. The Issuer does not expect to be a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes, and therefore believes that the Securities and Conversion Shares should not be treated as stock of a PFIC, but this conclusion is a factual determination made annually and thus may be subject to change. In general, the Issuer will be a PFIC with respect to you if, for any taxable year in which you hold the Securities or Conversion Shares, either (i) at least 75% of the gross income of the Issuer for the taxable year is passive income or (ii) at least 50% of the value, generally determined on the basis of a quarterly average, of the Issuer’s assets is attributable to assets that produce or are held for the production of passive income (including cash). If the Issuer were to be treated as a PFIC, U.S. holders of Securities or Conversion Shares would be required (i) to pay a special addition to tax on certain distributions and gains on sale and (ii) to pay tax on any gain from the sale or other disposition of Securities or Conversion Shares at ordinary income (rather than capital gains) rates in addition to paying the special addition to tax on this gain. Additionally, in certain circumstances the receipt of the Conversion Shares following an Automatic Conversion could be treated as a taxable disposition of the Securities. Further, with respect to any amounts treated as dividends paid on the Securities or Conversion Shares, as applicable, as described above under “—Tax Characterization and Distributions on the Securities and Conversion Shares,” if the Issuer were a PFIC in either the taxable year of the Issuer in which such dividend is paid or in the preceding taxable year, such dividends generally would not be “qualified dividend income” taxable to you at the preferential rates applicable to long-term capital gains. Holders of the Securities should consult their tax advisers regarding the potential application of the PFIC regime.

Information with Respect to Foreign Financial Assets. Owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 on the last day of the taxable year or $75,000 at any time during the taxable year, may be required to file an information report with respect to such assets with their tax returns. “Specified foreign financial assets” may include financial accounts maintained by foreign financial institutions, as well as the following, but only if they are held for investment and not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts that have non-U.S. issuers or counterparties, and (iii) interests in foreign entities. The Securities and Conversion Shares may be subject to these rules. Holders of the Securities are urged to consult their tax advisors regarding the application of this reporting requirement to their ownership of the Securities or Conversion Shares.

Information Reporting and Backup Withholding. If you are a non-corporate U.S. holder, information reporting requirements, on IRS Form 1099, generally would apply to payments of interest, and the payment of proceeds to you from the sale of Securities or Conversion Shares effected at a United States office of a broker.

Additionally, backup withholding may apply to such payments if you fail to comply with applicable certification requirements or (in the case of interest payments) are notified by the IRS that you have failed to report all interest and dividends required to be shown on your federal income tax returns.

Payment of the proceeds from the sale of Securities or Conversion Shares effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale effected at a foreign office of a broker could be subject to information reporting in the same manner as a sale within the United States (and in certain cases may be subject to backup withholding as well) if (i) the broker has certain connections to the United States, (ii) the proceeds or confirmation are sent to the United States or (iii) the sale has certain other specified connections with the United States.

You generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed your income tax liability by filing a refund claim with the IRS.

United Kingdom Taxation

The following is a summary of certain material U.K. withholding taxation matters at the date hereof in relation to payments of principal and interest in respect of the Securities and certain U.K. stamp duty and stamp duty reserve tax implications of acquiring, holding and disposing of the Securities. Save where expressly stated

to the contrary, it is based on current U.K. law and the published practice of His Majesty’s Revenue & Customs (“HMRC”), (which may not be binding on HMRC and may be subject to change, sometimes with retrospective effect), in each case at the latest practical date before the date of this document. The comments do not deal with other U.K. tax aspects of acquiring, holding or disposing of the Securities. The comments relate only to the position of persons who are absolute beneficial owners of the Securities and who hold the Securities as investments. The following is a general guide and should be treated with appropriate caution. It is not intended as tax advice and it does not purport to describe all of the tax considerations that might be relevant to a prospective purchaser. Holders of the Securities who are in any doubt as to their tax position should consult their professional advisers. Holders of the Securities who may be liable to taxation in jurisdictions other than the U.K. in respect of their acquisition, holding or disposal of the Securities are particularly advised to consult their professional advisers as to whether they are so liable (and if so under the laws of which jurisdictions), since the following comments relate only to certain U.K. taxation aspects. In particular, holders of the Securities should be aware that they may be liable to taxation under the laws of other jurisdictions in relation to payments in respect of the Securities even if such payments may be made without withholding or deduction for or on account of taxation under the laws of the U.K.

Payments of Interest

The Securities issued by the Issuer which carry a right to interest will constitute “quoted Eurobonds” provided they are and continue to be listed on a recognized stock exchange (within the meaning of section 1005 of the Income Tax Act 2007 (the “Act”) for the purpose of section 987 of the Act) or admitted to trading on a “multilateral trading facility” operated by a regulated recognized stock exchange within the meaning of section 987 of the Act.

While the Securities are and continue to be quoted Eurobonds, payments of interest on the Securities may be made without withholding or deduction for or on account of U.K. income tax.

The Issuer’s understanding is that the ISM is a multilateral trading facility operated by a regulated recognized stock exchange for the purposes of section 987 of the Act.

Under current U.K. legislation, if the exemption referred to above does not apply, interest on the Securities may fall to be paid under deduction of U.K. income tax at the basic rate (currently 20%) unless: (i) another relief applies under domestic law; or (ii) the Issuer has received a direction to the contrary from HMRC in respect of such relief as may be available pursuant to the provisions of any applicable double taxation treaty.

Other considerations

Where interest has been paid under deduction of U.K. income tax, holders of the Securities who are not resident in the U.K. for tax purposes may be able to recover all or part of the tax deducted if there is an appropriate provision in any applicable double taxation treaty.

The references to “interest” above mean “interest” as understood in U.K. tax law. The statements above do not take account of any different definitions of “interest” or “principal” which may prevail under any other law or which may be created by the terms and conditions of the Securities or any related documentation.

The above description of the U.K. withholding tax position assumes that there will be no substitution of the Issuer and does not consider the tax consequences of any such substitution.

S-98

Stamp duty and stamp duty reserve tax

1. The Finance Act 2019 introduced a new regime for hybrid capital instruments (the “HCI rules”). The HCI rules contain an exemption from all stamp duties on transfer so that no liability to U.K. stamp duty or stamp duty reserve tax should arise on the issue or transfer of the Securities provided that the Securities each constitute a “hybrid capital instrument” for the purposes of the HCI rules and there are no arrangements, the main purpose, or one of the main purposes, of which is to secure a tax advantage.

The Securities should constitute “hybrid capital instruments” for the purposes of the HCI rules provided that:

The Securities would “have no other significant equity features” provided that:

The Issuer will make a hybrid capital election in respect of the Securities within the required timeframe pursuant to section 475C of the U.K. Corporation Tax Act 2009 and the Securities are not being issued in consequence of, or otherwise in connection with, any arrangements, the main purpose, or one of the main purposes of which, is to secure a tax advantage. Consequently, the Issuer expects that the HCI rules should apply to the Securities such that they would benefit from an exemption from all stamp duties.

2. No liability to U.K. stamp duty or stamp duty reserve tax will generally arise on a cash redemption of Securities, provided no issue or transfer of shares or other securities is effected upon or in connection with such redemption.

3. No liability to U.K. stamp duty or stamp duty reserve tax will arise for a holder of the Securities on the release of Securities on Automatic Conversion.

4. No liability to U.K. stamp duty or stamp duty reserve tax will arise for a holder of the Securities on the issuance of new ordinary shares in Barclays PLC by Barclays PLC to holders of the Securities under an Automatic Conversion.

5. U.K. stamp duty and stamp duty reserve tax may be payable in relation to a Conversion Shares Offer.

BENEFIT PLAN INVESTOR CONSIDERATIONS

A fiduciary of a pension, profit-sharing or other employee benefit plan subject to the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or any entity or account deemed to hold “plan assets” of the foregoing (each, a “Plan”), should consider the fiduciary standards of ERISA in the context of the Plan’s particular circumstances before authorizing an investment in the Securities. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the Plan, and whether the investment would involve a prohibited transaction under ERISA or the Code.

General Fiduciary Considerations

The fiduciary provisions of ERISA, and the other rules and regulations applicable to Plans that are not subject to ERISA, impose certain obligations on Plan investors and may impose limitations on investment in the Securities. In determining whether to make an investment in the Securities, fiduciaries of Plan investors should carefully consider such provisions in consultation with their advisers. In addition, each Plan should consider the fact that none of the Issuer, the Calculation Agent, the Trustee, the Principal Paying Agent, the underwriters and/or any of their respective affiliates or employees (the “Transaction Parties”) will act as a fiduciary to any Plan with respect to the decision to invest such Plan’s assets in the Securities.

Prohibited Transactions

Section 406 of ERISA and Section 4975 of the Code prohibit Plans, as well as individual retirement accounts, Keogh plans, any other plans that are subject to Section 4975 of the Code and entities and accounts deemed to hold “plan assets” subject to ERISA and/or Section 4975 of the Code (also, “Plans”), from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to the Plan. A violation of these prohibited transaction rules may result in excise tax or other liabilities under ERISA or the Code for those persons, unless exemptive relief is available under an applicable statutory, regulatory or administrative exemption. Employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) (“Non-ERISA Arrangements”) are not subject to the requirements of Section 406 of ERISA or Section 4975 of the Code but may be subject to similar provisions under applicable federal, state, local, non-U.S. or other laws (“Similar Laws”).

The Transaction Parties may be considered a party in interest or disqualified person with respect to many Plans. The acquisition and holding of the Securities by a Plan with respect to which any Transaction Party is or becomes a party in interest or disqualified person may result in a prohibited transaction under ERISA or Section 4975 of the Code, unless the Securities are acquired and held pursuant to an applicable exemption. The U.S. Department of Labor has issued five prohibited transaction class exemptions, or “PTCEs,” that may provide exemptive relief if required for direct or indirect prohibited transactions that may arise from the purchase or holding of the Securities. These exemptions are PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 95-60 (for transactions involving certain insurance company general accounts), and PTCE 96-23 (for transactions managed by in-house asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide an exemption for the purchase and sale of the Securities, provided that neither the Issuer nor any of its affiliates has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of any Plan involved in the transaction, and provided further that the Plan pays no more and receives no less than “adequate consideration” in connection with the transaction (the “service provider exemption”). There can be no assurance that all of the conditions of any such exemptions (or any other exemption) will be satisfied.

S-100

Plan Asset Considerations

The U.S. Department of Labor has issued a regulation (29 C.F.R. Section 2510.3-101), as modified by Section 3(42) of ERISA, concerning the definition of what constitutes the assets of a Plan for purposes of ERISA and Section 4975 of the Code (“Plan Asset Regulation”). The Plan Asset Regulation provides that, as a general rule, the underlying assets and properties of corporations, partnerships, trusts and certain other entities would be treated as “plan assets” of a Plan investing therein for purposes of ERISA and/or Section 4975 of the Code only if the Plan acquired an “equity interest” in such entity (i.e., an interest other than an instrument which is treated as indebtedness under applicable local law and which has no substantial equity features) and none of the exceptions to holding “plan assets” contained in the Plan Asset Regulation applied. Under one such exception, the assets of an entity will not be considered “plan assets” as a result of a Plan’s equity investment in such entity where such entity is an “operating company” (i.e., an entity that is primarily engaged, through majority-and/or wholly-owned subsidiaries, in producing a product or providing a service other than the investment of capital). Under another such exception, the assets of an entity will not be considered “plan assets” where a Plan makes an investment in an equity interest of such entity that is a “publicly-offered security.” A “publicly-offered security” is a security that is (a) “freely transferable,”(b) part of a class of securities that is “widely held” and (c) either part of a class of securities that is registered under Section 12(b) or 12(g) of the Exchange Act or sold to the Plan as part of an offering of securities to the public pursuant to an effective registration statement under the Securities Act and the class of securities of which such security is a part is registered under the Exchange Act within 120 days (or such later time as may be allowed by the SEC) after the end of the fiscal year of the issuer during which the offering of such securities to the public occurred.

ERISA and Similar Law Representations

Any purchaser or holder of the Securities or any interest therein will be deemed to have represented by its purchase and holding of the Securities or any interest therein that either (1) it is not a Plan or Non-ERISA Arrangement and is not purchasing the Securities on behalf of, or with the assets of, any Plan or Non-ERISA Arrangement or (2)(i) the purchase and holding of the Securities will not constitute a non-exempt prohibited transaction under ERISA or the Code or a similar violation under any applicable Similar Laws and (ii) none of the Transaction Parties directly or indirectly exercises any discretionary authority or control or renders investment advice or otherwise acts in a fiduciary capacity with respect to the assets of the Plan within the meaning of ERISA.

Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is important that fiduciaries or other persons considering purchasing the Securities on behalf of or with the assets of any Plan or Non-ERISA Arrangement consult with their counsel regarding the availability of exemptive relief under any of the PTCEs listed above, the service provider exemption, or any other applicable exemption, or the potential consequences of any purchase or holding under Similar Laws, as applicable.

Purchasers of the Securities have exclusive responsibility for ensuring that their purchase and holding of the Securities do not violate the fiduciary or prohibited transaction rules of ERISA or the Code or any similar provisions of Similar Laws. The sale of any Securities to a Plan or Non-ERISA Arrangement is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement or that such investment is appropriate for such Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

UNDERWRITING (CONFLICTS OF INTEREST)

Subject to the terms and conditions set forth in the Underwriting Agreement—Standard Provisions, dated March 3, 2021 (the “Underwriting Agreement”), incorporated in the pricing agreement dated May 8, 2024 (as integrated by the Underwriting Agreement, the “Pricing Agreement”), between us and the underwriters named below, we have agreed to issue to the underwriters, and each underwriter has severally undertaken to purchase, the principal amount of Securities set forth opposite its name below:

The Pricing Agreement provides that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters have undertaken to purchase all the Securities offered by this prospectus supplement if any of these Securities are purchased.

The underwriters propose to offer the Securities directly to the public at the price to public set forth on the cover of this prospectus supplement.

We estimate that our total expenses for the offering, excluding underwriting commissions, will be approximately £330,000.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

The Securities are new issue securities with no established trading market. Application will be made to the LSE for the Securities to be admitted to trading on the ISM. The Securities are expected to be admitted to trading on the ISM from on or about May 15, 2024. Settlement of the Securities will occur through Clearstream, Luxembourg and/or Euroclear for value on the Issue Date. The ISIN is XS2813323503 and the Common Code is 281332350. For more information, see also “General Information for the International Securities Market” below.

S-102

Certain of the underwriters may not be U.S. registered broker-dealers and accordingly will not effect any sales within the United States except in compliance with applicable U.S. laws and regulations, including the rules of FINRA.

Certain of the underwriters and their affiliates have performed investment banking and advisory services for us from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may from time to time engage in transactions with and perform services for us in the ordinary course of business.

It is expected that delivery of the Securities will be made for value on or about May 15, 2024, which will be the fifth (5th) business day in the United States following the date of pricing of the Securities. Under Rule 15c6-1 under the Securities Exchange Act of 1934, purchases or sales of Securities in the secondary market generally are required to settle within two (2) business days (T+2), unless the parties to any such transaction expressly agree otherwise. Accordingly, purchasers of the Securities who wish to trade the Securities on the date of this prospectus supplement or the next two (2) succeeding business days will be required, because the Securities initially will settle within five (5) business days (T+5) in the United States, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Securities who wish to trade the Securities prior to two (2) business days before delivery should consult their own legal advisers.

Conflicts of Interest

Barclays Bank PLC, the Sole Structuring Adviser and Sole Bookrunner, is an affiliate of Barclays Capital Inc. Because Barclays Capital Inc. is an affiliate of the Issuer, it is deemed to have a conflict of interest in this offering within the meaning of Rule 5121 (or any successor rule thereto) (“Rule 5121”) of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Consequently, this offering is being conducted in compliance with the provisions of Rule 5121. Neither Barclays Capital Inc. nor Barclays Bank PLC is permitted to sell Securities in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

Stabilization Transactions and Short Sales

In connection with the offering, the underwriters may purchase and sell Securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Securities than they are required to purchase in the offering. The underwriters may close a short position by purchasing Securities in the open market. Stabilizing transactions consist of various bids for or purchases of the Securities made by the underwriters in the open market prior to the completion of the offering.

Purchases to cover a short position and stabilizing transactions may have the effect of preventing or retarding a decline in the market price of the Securities. As a result, the price of the Securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time.

Broker-dealers and other persons are cautioned that some of their activities may result in their being deemed participants in the distribution of the Securities of any series in a manner that would render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act. Among other activities, broker-dealers and other persons may make short sales of the Securities of any series and may cover such short positions by borrowing Securities from us or our affiliates or by purchasing Securities from us or our affiliates subject to our obligation to repurchase such Securities at a later date. As a result of these activities, these market participants may be deemed statutory underwriters. A determination of whether a particular market participant is an underwriter must take into account all the facts and circumstances pertaining to the activities of the participant in the particular case, and the example mentioned above should not be considered

S-103

a complete description of all the activities that would lead to designation as an underwriter and subject a market participant to the prospectus delivery and liability provisions of the Securities Act. This prospectus will be deemed to cover any short sales of Securities of any series by market participants who cover their short positions with Securities borrowed or acquired from us or our affiliates in the manner described above.

Market-Making Resales

This prospectus supplement and the accompanying prospectus may be used by an affiliate of the Issuer in connection with offers and sales of the Securities in market-making transactions. In a market-making transaction, such affiliate may resell the Securities it acquires from other holders, after the original offering and sale of the Securities, or may make short sales of the Securities and may cover such short positions by borrowing the Securities from the Issuer, its affiliates or others, or by purchasing the Securities from the Issuer, its affiliates or others subject to an obligation to repurchase such Securities at a later date. Resales of this kind may occur in the open market or may be privately negotiated, at prevailing market prices at the time of resale or at related or negotiated prices. In these transactions, such affiliate may act as principal, or agent, including as agent for the counterparty in a transaction in which such affiliate acts as principal, or as agent for both counterparties in a transaction in which such affiliate does not act as principal. This prospectus supplement and the accompanying prospectus will be deemed to cover any short sales of the Securities by market participants, including the Issuer or affiliates, and any return of the Securities borrowed or acquired from the Issuer, its affiliates or others, or any equivalent securities, to cover their short positions and any other transaction or transfer in connection therewith in the manner described above.

Such affiliate may receive compensation in the form of discounts and commissions, including from both counterparties in some cases.

The price to public specified on the cover of this prospectus supplement relates to the initial offering of the Securities. This amount does not relate to Securities sold in market-making transactions.

We do not expect to receive any proceeds from market-making transactions.

Information about the trade and settlement dates, as well as the purchase price, for a market-making transaction will be provided to the purchaser in a separate confirmation of sale.

TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This prospectus and certain documents incorporated by reference herein contain certain forward-looking statements within the meaning of Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Section 27A of the U.S. Securities Act of 1933, as amended (the “Securities Act”), with respect to the Group (as defined below). We caution readers that no forward-looking statement is a guarantee of future performance and that actual results or other financial condition or performance measures could differ materially from those contained in the forward-looking statements. Forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements sometimes use words such as “may,” “will,” “seek,” “continue,” “aim,” “anticipate,” “target,” “projected,” “expect,” “estimate,” “intend,” “plan,” “goal,” “believe,” “achieve” or other words of similar meaning. Examples of forward-looking statements include, among others, statements or guidance regarding or relating to the Group’s future financial position, business strategy, income levels, costs, assets and liabilities, impairment charges, provisions, capital, leverage and other regulatory ratios, capital distributions (including policy on dividends and share buybacks), return on tangible equity, projected levels of growth in banking and financial markets, industry trends, any commitments and targets (including environmental, social and governance (“ESG”) commitments and targets), plans and objectives for future operations and other statements that are not historical or current facts. By their nature, forward-looking statements involve risk and uncertainty because they relate to future events and circumstances. Forward-looking statements speak only as at the date on which they are made. Forward-looking statements may be affected by a number of factors, including, without limitation: changes in legislation, regulations, governmental and regulatory policies, expectations and actions, voluntary codes of practices and the interpretation thereof, changes in International Financial Reporting Standards (“IFRS”) and other accounting standards, including practices with regard to the interpretation and application thereof and emerging and developing ESG reporting standards; the outcome of current and future legal proceedings and regulatory investigations; the Group’s ability along with governments and other stakeholders to measure, manage and mitigate the impacts of climate change effectively; environmental, social and geopolitical risks and incidents, pandemics and similar events beyond the Group’s control; the impact of competition in the banking and financial services industry; capital, liquidity, leverage and other regulatory rules and requirements applicable to past, current and future periods; United Kingdom (“U.K.”), United States (“U.S.”), Eurozone and global macroeconomic and business conditions, including inflation; volatility in credit and capital markets; market related risks such as changes in interest rates and foreign exchange rates; reforms to benchmark interest rates and indices; higher or lower asset valuations; changes in credit ratings of any entity within the Group or any securities issued by it; changes in counterparty risk; changes in consumer behavior; the direct and indirect consequences of the conflicts in Ukraine and the Middle East on European and global macroeconomic conditions, political stability and financial markets; political elections; developments in the U.K.’s relationship with the European Union (“E.U.”); the risk of cyber-attacks, information or security breaches, technology failures or other operational disruptions and any subsequent impacts on the Group’s reputation, business or operations; the Group’s ability to access funding; and the success of acquisitions, disposals and other strategic transactions. A number of these factors are beyond the Group’s control. As a result, the Group’s actual financial position, results, financial and non-financial metrics or performance measures or its ability to meet commitments and targets may differ materially from the statements or guidance set forth in the Group’s forward-looking statements. In setting our targets and outlook for the period 2024-2026, we have made certain assumptions about the macro-economic environment, including, without limitation, inflation, interest and unemployment rates, the different markets and competitive conditions in which we operate, and our ability to grow certain businesses and achieve costs savings and other structural actions. The list above is not exhaustive and there are other factors that may cause our actual results to differ materially from the forward-looking statements contained in this prospectus and the documents incorporated by reference herein. You are also advised to read carefully the risk factors set out in the section entitled “Risk Factors” in our filings with the U.S. Securities and Exchange Commission (the “SEC”), including, without limitation, in our Annual Report on Form 20-F for the financial year ended December 31, 2023 (File No. 001-09246), filed with the SEC on February 20, 2024 (the “2023 Form 20-F”), which are available on the SEC’s website at http://www.sec.gov for a discussion of certain factors that should be considered when deciding what action to take in relation to the securities.

Subject to our obligations under the applicable laws and regulations of any relevant jurisdiction, (including, without limitation, the U.K. and the U.S.), in relation to disclosure and ongoing information, we undertake no obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

DESCRIPTION OF DEBT SECURITIES

The following is a summary of the general terms of the debt securities (as defined below). It sets forth possible terms and provisions for each series of debt securities. Each time that we offer debt securities, we will prepare and file a prospectus supplement with the SEC, which you should read carefully. The prospectus supplement may contain additional terms and provisions of those debt securities. If there is any inconsistency between the terms and provisions presented here and those in the prospectus supplement, those in the prospectus supplement will apply and will replace those presented here.

The debt securities of any series will be either our senior obligations (the “Senior Debt Securities”) or our dated subordinated obligations (the “Dated Subordinated Debt Securities” and, together with the Senior Debt Securities, the “debt securities”). Neither the Senior Debt Securities nor the Dated Subordinated Debt Securities will be secured by any assets or property of Barclays PLC or any of its subsidiaries or affiliates (including Barclays Bank PLC, its subsidiary).

We will issue Senior Debt Securities and Dated Subordinated Debt Securities, respectively, under the Senior Debt Securities Indenture dated as of January 17, 2018, between us and The Bank of New York Mellon, London Branch, as trustee (as heretofore supplemented and amended, the “Senior Debt Securities Indenture”) and the Dated Subordinated Debt Securities Indenture dated as of May 9, 2017, between us and The Bank of New York Mellon, London Branch, as trustee (as heretofore supplemented and amended, the “Dated Subordinated Debt Securities Indenture”). The terms of the debt securities include those stated in the relevant indenture and any supplements thereto, and those terms made part of the relevant indenture by reference to the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Senior Debt Securities Indenture and Dated Subordinated Debt Securities Indenture and any supplements thereto are sometimes referred to in this section of the prospectus individually as an “indenture” and collectively as the “indentures.” We have filed the indentures as exhibits to the registration statement of which this prospectus is a part.

Because this section is a summary, it does not describe every aspect of the debt securities in detail. This summary is subject to, and qualified by reference to, all of the definitions and provisions of the relevant indenture, any supplement to the relevant indenture and the form of the instrument representing each series of debt securities. Certain terms, unless otherwise defined here, have the meaning given to them in the relevant indenture.

References to “you” and “holder” in the subsections to this section “Description of Debt Securities,” entitled “—Ranking,” “—No Set-off,” “—Agreement with Respect to the Exercise of U.K. Bail-in Power,” “—Subsequent Holders’ Agreement,” “—Payment of Debt Security Additional Amounts,” “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits—Senior Enforcement Events and Remedies—Limited remedies for breach of obligations (other than non-payment),” “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits —Senior Enforcement Events and Remedies—No other remedies,” “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits—Dated Subordinated Enforcement Events and Remedies—Limited remedies for breach of obligations (other than non-payment)” and “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits —Dated Subordinated Enforcement Events and Remedies—No other remedies” below, include beneficial owners of the debt securities.

General

The debt securities are not deposit liabilities of Barclays PLC and are not insured by any regulatory body of the United States or the United Kingdom.

-7-

Because we are a holding company, our rights to participate in the assets of any of our subsidiaries upon its liquidation will be subject to the prior claims of the subsidiaries’ creditors, including, in the case of our bank subsidiaries, their respective depositors, except, in our case, to the extent that we may ourselves be a creditor with recognized claims against the relevant subsidiary.

The indentures do not limit the amount of debt securities that we may issue. We may issue the debt securities in one or more series, or as units comprised of two or more related series. The prospectus supplement will indicate for each series or of two or more related series of debt securities:

-8-

If we issue debt securities in bearer form, the special restrictions and considerations relating to such bearer debt securities, including applicable offering restrictions and U.S. tax considerations, will be described in the relevant prospectus supplement.

Debt securities may bear interest at a fixed rate or a floating rate or we may sell debt securities that bear no interest or that bear interest at a rate below the prevailing market interest rate or we may sell Senior Debt Securities at a discount to their stated principal amount (“Discount Senior Debt Securities”). The relevant prospectus supplement will describe special U.S. federal income tax considerations applicable to Discount Senior Debt Securities or to debt securities issued at par that are treated for U.S. federal income tax purposes as having been issued at a discount.

The prospectus supplement relating to any series of debt securities may also include, if applicable, a discussion of considerations under the Employee Retirement Income Security Act of 1974, as amended.

Holders of debt securities have no voting rights except as explained in this section below under “—Modification and Waiver” and “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits.”

If we issue Senior Debt Securities designed to count towards any minimum requirements for own funds and eligible liabilities and/or loss absorbing capacity for the purposes of the Capital Regulations, the terms of such Senior Debt Securities may differ from those described in this prospectus and will be set out in the accompanying prospectus supplement.

-9-

If we issue Dated Subordinated Debt Securities that qualify as Tier 2 Capital or other capital for the purposes of the Capital Regulations, the terms may vary from those described in this prospectus and will be set forth in the accompanying prospectus supplement.

Market-Making Transactions. If you purchase your debt security in a market-making transaction, you will receive information about the price you pay and your trade and settlement dates in a separate confirmation of sale. A market-making transaction is one in which Barclays Capital Inc. or another of our affiliates resells a security that it has previously acquired from another holder. A market-making transaction in a particular debt security occurs after the original issuance and sale of the debt security.

Payments

The relevant prospectus supplement will specify the date on which we will pay interest, if any, the date for payments of principal and any premium, on any particular series of debt securities. The prospectus supplement will also specify the interest rate or rates, if any, or how the rate or rates will be calculated.

Ranking

Senior Debt Securities. Senior Debt Securities constitute our direct, unconditional, unsecured and unsubordinated obligations ranking pari passu without any preference among themselves. In the event of our winding-up or administration, the Senior Debt Securities will rank pari passu with all our other outstanding unsecured and unsubordinated obligations, present and future, except such obligations as are preferred by operation of law.

Pursuant to the U.K. Insolvency Act 1986, as amended or replaced from time to time (the “Insolvency Act”), the Senior Debt Securities will constitute ordinary non-preferential debt of the Issuer and will rank in priority to secondary non-preferential debts and tertiary non-preferential debts. The terms “ordinary non-preferential debt,” “secondary-non preferential debt” and “tertiary non-preferential debt” shall have the meanings given to each of them in the Insolvency Act.

Dated Subordinated Debt Securities. Dated Subordinated Debt Securities constitute our direct, unsecured and subordinated obligations ranking pari passu without any preference among themselves.

Unless the applicable prospectus supplement provides otherwise, in the event of our winding-up or administration, the claims of the trustee (on behalf of the holders of the Dated Subordinated Debt Securities but not the rights and claims of the trustee in its personal capacity under the Dated Subordinated Debt Securities Indenture) and the holders of the Dated Subordinated Debt Securities against us, in respect of such Dated Subordinated Debt Securities (including any damages or other amounts (if payable)) shall:

(i) be subordinated to the claims of all Senior Creditors;

(ii) rank at least pari passu with the claims in respect of Parity Obligations and with the claims of all other subordinated creditors of the Issuer which in each case by law rank, or by their terms are expressed to rank, pari passu with the Dated Subordinated Debt Securities; and

(iii) rank senior to the Issuer’s ordinary shares, preference shares and any junior subordinated obligations (including Junior Obligations) or other securities which in each case either by law rank, or by their terms are expressed to rank, junior to the Dated Subordinated Debt Securities.

“Secondary non-preferential debts” shall have the meaning given to it in the Insolvency Act.

-10-

“Senior Creditors” with respect to a particular series of Dated Subordinated Debt Securities, means creditors of the Issuer (i) who are unsubordinated creditors; (ii) who are subordinated creditors (whether in the event of a winding-up or administration of the Issuer or otherwise) other than (x) those whose claims by law rank, or by their terms are expressed to rank, pari passu with or junior to the claims of the holders of the Dated Subordinated Debt Securities or (y) those whose claims are in respect of Parity Obligations or Junior Obligations; or (iii) who are creditors in respect of any secondary non-preferential debts.

“Parity Obligations” with respect to a particular series of Dated Subordinated Debt Securities, shall have the meaning set forth in the applicable prospectus supplement.

“Junior Obligations” with respect to a particular series of Dated Subordinated Debt Securities, shall have the meaning set forth in the applicable prospectus supplement.

In the event of our winding-up or liquidation, if any amount in respect of the Dated Subordinated Debt Securities is paid to the holders of such Dated Subordinated Debt Securities or to the trustee (including any damages or other amounts (if payable)) before the claims of Senior Creditors, then such payment or distribution shall be held by such holders or the trustee upon trust to be applied in the following order: (i) to the amounts due to the trustee in connection with the Dated Subordinated Debt Securities Indenture, the Dated Subordinated Debt Securities and the acceptance or administration of the trust or trusts under the Dated Subordinated Debt Securities Indenture; (ii) in payment of all claims of Senior Creditors outstanding at the commencement of, or arising solely by virtue of, a winding-up of the Issuer to the extent that such claims shall be admitted in the winding-up and shall not be satisfied out of the Issuer’s other resources; and (iii) in payment of Dated Subordinated Debt Securities issued under the Dated Subordinated Debt Securities Indenture. By accepting the Dated Subordinated Debt Securities, each holder agrees to be bound by the Dated Subordinated Debt Securities Indenture’s subordination provisions and irrevocably authorizes the Issuer’s liquidator to perform on behalf of the holder the above subordination trust.

Pursuant to the Insolvency Act, the Dated Subordinated Debt Securities will constitute tertiary non-preferential debts of the Issuer and therefore both ordinary non-preferential debts and secondary non-preferential debts will rank ahead of any claims in respect of the Dated Subordinated Debt Securities.

No Set-off

Subject to applicable law and unless the applicable prospectus supplement provides otherwise, no holder of debt securities may exercise, claim or plead any right of set-off, compensation, counterclaim, retention or netting in respect of any amount owed to it by us arising under, or in connection with, the debt securities and the Senior Debt Securities Indenture or Dated Subordinated Debt Securities Indenture, as applicable, and each holder of debt securities shall, by virtue of its holding of any debt security (or any beneficial interest therein), be deemed, to the fullest extent permitted under applicable law, to have waived all such rights of set-off, compensation, counterclaim, retention and netting. Notwithstanding the foregoing, if any amounts due and payable to any holder of the debt securities by us in respect of, or arising under, the debt securities or the relevant indenture are discharged by set-off, compensation, counterclaim, retention or netting, such holder shall, subject to applicable law and unless the applicable prospectus supplement provide otherwise, immediately pay to us an amount equal to the amount of such discharge (or, in the event of our winding-up or administration, our liquidator or administrator, as the case may be) and, until such time as payment is made, shall hold an amount equal to such amount in trust for us (or our liquidator or administrator, as the case may be) and, accordingly, any such discharge shall be deemed not to have taken place. By its acquisition of debt securities, each holder agrees to be bound by these provisions relating to waiver of set-off, compensation, counterclaim, retention and netting. No

-11-

holder of debt securities shall be entitled to proceed directly against us except as described in “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits—Limitation on Suits” below.

Agreement with Respect to the Exercise of U.K. Bail-in Power

Notwithstanding and to the exclusion of any other term of the debt securities or any other agreements, arrangements or understandings between the Issuer and any holder or the trustee on behalf of the holders of debt securities, by acquiring debt securities, each holder of debt securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the Relevant U.K. Resolution Authority that may result in (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, the debt securities; (ii) the conversion of all, or a portion of, the principal amount of, or interest on, the debt securities into shares or other securities or other obligations of the Issuer or another person (and the issue to, or conferral on, the holder of the debt securities of such shares, securities or obligations); (iii) the cancellation of the debt securities and/or (iv) the amendment or alteration of the maturity of the debt securities, or amendment of the amount of interest due on the debt securities, or the dates on which interest becomes payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the debt securities solely to give effect to the exercise by the Relevant U.K. Resolution Authority of such U.K. Bail-in Power. Each holder further acknowledges and agrees that the rights of the holders of the debt securities are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders of the debt securities may have at law if and to the extent that any U.K. Bail-in Power is exercised by the Relevant U.K. Resolution Authority in breach of laws applicable in England.

For the purposes of the debt securities, a “U.K. Bail-in Power” is any write-down, conversion, transfer, modification and/or suspension power existing from time to time under any laws, regulations, rules or requirements relating to the resolution of banks, banking group companies, credit institutions and/or investment firms incorporated in the United Kingdom in effect and applicable in the United Kingdom to the Issuer or other members of the Group, including but not limited to any such laws, regulations, rules or requirements that are implemented, adopted or enacted within the context of any applicable European Union directive or regulation of the European Parliament and of the Council establishing a framework for the recovery and resolution of credit institutions and investment firms, and/or within the context of a U.K. resolution regime under the U.K. Banking Act 2009, as the same has been or may be amended from time to time (whether pursuant to the U.K. Financial Services (Banking Reform) Act 2013, secondary legislation or otherwise, the “Banking Act”), pursuant to which obligations of a bank, banking group company, credit institution or investment firm or any of its affiliates can be reduced, cancelled, amended, transferred and/or converted into shares or other securities or obligations of the obligor or any other person (and a reference to the “Relevant U.K. Resolution Authority” is to any authority with the ability to exercise a U.K. Bail-in Power).

No repayment of the principal amount of the debt securities or payment of interest on the debt securities shall become due and payable after the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority unless such repayment or payment would be permitted to be made by the Issuer under the laws and regulations of the United Kingdom and the European Union applicable to the Issuer.

By its acquisition of the debt securities, each holder of debt securities, to the extent permitted by the Trust Indenture Act, waives any and all claims against the trustee for, agrees not to initiate a suit against the trustee in respect of, and agrees that the trustee shall not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the debt securities.

-12-

Upon the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the debt securities, the Issuer shall provide a written notice to DTC as soon as practicable regarding such exercise of the U.K. Bail-in Power for purposes of notifying holders of such occurrence. The Issuer shall also deliver a copy of such notice to the trustee for information purposes. Any delay or failure by the Issuer in delivering any notice referred to in this paragraph shall not affect the validity and enforceability of the U.K. Bail-in Power.

By its acquisition of the debt securities, each holder of debt securities acknowledges and agrees that the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to a particular series of debt securities shall not give rise to a default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act.

The Issuer’s obligations to indemnify the trustee in accordance with the indentures shall survive the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the debt securities.

By its acquisition of the debt securities, each holder of debt securities acknowledges and agrees that, upon the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the debt securities, (a) the trustee shall not be required to take any further directions from holders of the debt securities under Section 5.12 (Control by Holders) of the Senior Debt Securities Indenture or Section 5.13 (Control by Holders) of the Dated Subordinated Debt Securities Indenture, as applicable, which sections authorize holders of a majority in aggregate principal amount of the outstanding debt securities of the relevant series of Senior Debt Securities or Dated Subordinated Debt Securities to direct certain actions relating to the relevant debt securities and (b) the Senior Debt Securities Indenture and the Dated Subordinated Debt Securities Indenture, as applicable, shall impose no duties upon the trustee whatsoever with respect to the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority. Notwithstanding the foregoing, if, following the completion of the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority in respect of the debt securities, the debt securities remain outstanding (for example, if the exercise of the U.K. Bail-in Power results in only a partial write-down of the principal of the debt securities), then the trustee’s duties under the Senior Debt Securities Indenture or Dated Subordinated Debt Securities Indenture shall remain applicable with respect to the debt securities following such completion to the extent that the Issuer and the trustee shall agree pursuant to a supplemental indenture to the Senior Debt Securities Indenture or the Dated Subordinated Debt Securities Indenture, as applicable, or an amendment thereto.

By its acquisition of the debt securities, each holder of debt securities shall be deemed to have (a) consented to the exercise of any U.K. Bail-in Power as it may be imposed without any prior notice by the Relevant U.K. Resolution Authority of its decision to exercise such power with respect to the debt securities and (b) authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such debt securities to take any and all necessary action, if required, to implement the exercise of any U.K. Bail-in Power with respect to the debt securities as it may be imposed, without any further action or direction on the part of such holder or the trustee.

The exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the debt securities shall not constitute a Senior Enforcement Event or a Dated Subordinated Enforcement Event, as applicable.

The relevant prospectus supplement may describe additional or alternative related provisions with respect to the U.K. Bail-in Power, including certain waivers by the holders of debt securities of certain claims against the trustee, to the extent permitted by the Trust Indenture Act.

Subsequent Holders’ Agreement

Holders of debt securities that acquire debt securities in the secondary market shall be deemed to acknowledge, agree to be bound by and consent to the same provisions specified herein and in the applicable prospectus supplement to the same extent as the holders of the debt securities that acquire the debt securities upon their initial issuance, including, without limitation, with respect to the acknowledgement and agreement to

-13-

be bound by and consent to the terms of the debt securities, including in relation to the U.K. Bail-in Power, the waiver of set-off provisions described under “—No Set-off” and, for the Dated Subordinated Debt Securities, the subordination provisions described under “—Ranking” and the limitations on remedies specified in “—Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits—Dated Subordinated Enforcement Events and Remedies—Limited remedies for breach of obligations (other than non-payment).”

Payment of Debt Security Additional Amounts

Unless the relevant prospectus supplement provides otherwise, we will pay any amounts to be paid by us on any series of debt securities without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”) now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the United Kingdom or any political subdivision or authority thereof or therein that has the power to tax (each, a “Taxing Jurisdiction”), unless the deduction or withholding is required by law. Unless the relevant prospectus supplement provides otherwise, if at any time a Taxing Jurisdiction requires us to deduct or withhold Taxes, we will pay the additional amounts of, or in respect of, any interest (but not principal or any premium) on the debt securities (“Debt Security Additional Amounts”) that are necessary so that the net amounts in respect of interest paid to the holders (excluding the beneficial owners), after the deduction or withholding, shall equal the amounts in respect of interest which would have been payable had no such deduction or withholding been required. However, we will not pay Debt Security Additional Amounts for Taxes:

Whenever we refer in this prospectus and any prospectus supplement to the payment of any interest on, or in respect of, any debt securities of any series, we mean to include the payment of Debt Security Additional Amounts to the extent that, in context, Debt Security Additional Amounts are, were or would be payable.

For the avoidance of doubt, unless the relevant prospectus supplement provides otherwise, any amounts to be paid by us or any paying agent on the debt securities will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant

-14-

to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (or any law implementing such an intergovernmental agreement) (a “FATCA Withholding Tax”), and neither we nor any paying agent will be required to pay Debt Security Additional Amounts on account of any FATCA Withholding Tax.

Unless the relevant prospectus supplement provides otherwise, any paying agent shall be entitled to make a deduction or withholding from any payment which it makes under the debt securities and the relevant indenture for or on account of (i) any present or future taxes, duties or charges if and to the extent so required by any applicable law and (ii) any FATCA Withholding Tax (together, “Applicable Law”). In either case, the paying agent shall make any payment after a deduction or withholding has been made pursuant to Applicable Law and shall report to the relevant authorities the amount so deducted or withheld. In all cases, the paying agent shall have no obligation to gross up any payment made subject to any deduction or withholding pursuant to Applicable Law. In addition, amounts deducted or withheld by the paying agent under this paragraph will be treated as paid to the holder of a debt security, and we will not pay Debt Security Additional Amounts in respect of such deduction or withholding, except to the extent the provisions in this subsection “—Payment of Debt Security Additional Amounts” explicitly provide otherwise.

Redemption

Redemption for Tax Reasons. Unless the relevant prospectus supplement provides otherwise, we may, at our option, at any time, redeem the debt securities of any series, in whole but not in part, upon not less than fifteen (15) nor more than sixty (60) days’ notice (or the shorter or longer notice period specified in the relevant prospectus supplement) to the holders at any time, if (A) in the case of the Senior Debt Securities, we are required to issue definitive debt securities (see “Description of Certain Provisions Relating to Debt Securities and Contingent Capital Securities—Special Situations When a Global Security Will Be Terminated”) and, as a result, we are or would be required to pay Debt Security Additional Amounts with respect to the Senior Debt Securities; or (B) we determine that as a result of a change in or amendment to the laws or regulations of a Taxing Jurisdiction, including any treaty to which the relevant Taxing Jurisdiction is a party, or a change in an official application of those laws or regulations, including a decision of any court or tribunal, which becomes effective on or after the issue date of the relevant series of debt securities (and, in the case of a successor entity, which becomes effective on or after the date of that entity’s assumption of our obligations), (i) we will or would be required to pay holders Debt Security Additional Amounts; (ii) we would not be entitled to claim a deduction in respect of any payments in respect of the relevant series of debt securities in computing our taxation liabilities or the value of the deduction would be materially reduced; (iii) we would not, as a result of the relevant series of debt securities being in issue, be able to have losses or deductions set against the profits or gains, or profits or gains offset by the losses or deductions, of companies with which we are or would otherwise be so grouped for applicable United Kingdom tax purposes (whether under the group relief system current as at the issue date of the relevant series of debt securities or any similar system or systems having like effect as may from time to time exist); (iv) in the case of any Dated Subordinated Debt Securities, we would have to treat the relevant series of Dated Subordinated Debt Securities or any part thereof as a derivative or an embedded derivative for United Kingdom tax purposes; or (v) in the case of any Dated Subordinated Debt Securities, we would, in the future, have to bring into account a taxable credit if the principal amount of the relevant series of Dated Subordinated Debt Securities were written down or converted (each such change in tax law or regulation or the official application thereof, a “Tax Event” for purposes of this “Description of Debt Securities” section), in each of cases (A) and (B) above, at an amount equal to 100% of the principal amount of the debt securities being redeemed together with accrued but unpaid interest, if any, on the principal amount of the debt securities to be redeemed to (but excluding) the date fixed for redemption; or, in the case of Discount Senior Debt Securities, such portion of the principal amount of such Discount Senior Debt Securities as may be specified by their terms, provided that in the case of each Tax Event, the consequences of the Tax Event cannot be avoided by us taking reasonable measures available to us.

-15-

In each case and unless the relevant prospectus supplement provides otherwise, before we give a notice of redemption (which notice shall be irrevocable), we shall be required to deliver to the trustee a written legal opinion of independent counsel of recognized standing, chosen by us, confirming that we are entitled to exercise our right of redemption. Any redemption of debt securities as a result of a Tax Event will also be subject to the provisions described under “—Notice of Redemption of Debt Securities” and “—Condition to Redemption of Debt Securities” below.

Optional Redemption. The relevant prospectus supplement will specify whether we may redeem the debt securities of any series, in whole or in part, at our option, in any additional circumstances. The prospectus supplement will also specify the notice we will be required to give, what prices and any premium we will pay, and the dates on which we may redeem the debt securities. Any notice of redemption of debt securities will state:

In the case of a partial redemption, the trustee shall select the debt securities that we will redeem in any manner it deems fair and appropriate. Any optional redemption of debt securities will also be subject to the provisions described under “—Notice of Redemption of Debt Securities” and “—Condition to Redemption of Debt Securities” below.

Notice of Redemption of Debt Securities

Unless the relevant prospectus supplement provides otherwise, any redemption of the debt securities shall be subject to our giving not less than fifteen (15) days’, nor more than sixty (60) days’, prior notice to the holders of such debt securities (unless a shorter or longer period is specified in the applicable prospectus supplement) via DTC or the relevant clearing system(s) (or, if the debt securities are held in definitive form, to the holders at their addresses shown on the register for the debt securities) (such notice being irrevocable except in the limited circumstances described in the following paragraph and as may be specified in the relevant prospectus supplement) specifying our election to redeem the relevant series of debt securities and the date fixed for such redemption. Notice by DTC to participating institutions and by these participants to street name holders of beneficial interests in the relevant series of debt securities will be made according to arrangements among them and may be subject to statutory or regulatory requirements.

If we have elected to redeem a particular series of debt securities but prior to the payment of the redemption amount with respect to such redemption the Relevant U.K. Resolution Authority exercises its U.K. Bail-in Power in respect of such series of debt securities, the relevant redemption notice shall be automatically rescinded and shall be of no force and effect, and no payment of the redemption amount will be due and payable.

Condition to Redemption of Debt Securities

Senior Debt Securities

Notwithstanding any other provision, and unless otherwise specified in the applicable prospectus supplement, we may redeem any series of Senior Debt Securities before their maturity date (and give notice thereof to the holders of the Senior Debt Securities) only if we have obtained the prior consent of the Relevant U.K. Resolution Authority (if such consent is then required by the Capital Regulations) for the redemption of the

-16-

Senior Debt Securities. In addition, any such redemption of any series of Senior Debt Securities shall be subject to the additional conditions set out under “—Additional Conditions Relating to Redemption and Repurchase of Debt Securities – Senior Debt Securities” below.

Dated Subordinated Debt Securities

Notwithstanding any other provision, and unless otherwise specified in the applicable prospectus supplement, we may redeem the Dated Subordinated Debt Securities before their maturity date (and give notice thereof to the holders of the Dated Subordinated Debt Securities) only if we have obtained the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations) for the redemption of the Dated Subordinated Debt Securities. In addition, any such redemption of any series of Dated Subordinated Debt Securities shall be subject to the additional conditions set out under “—Additional Conditions Relating to Redemption and Repurchase of Debt Securities – Dated Subordinated Debt Securities” below.

Condition to Repurchase of Debt Securities

Senior Debt Securities

Unless the applicable prospectus supplement provides otherwise, we or any member of the Group may purchase or otherwise acquire any outstanding Senior Debt Securities of any series at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the Relevant U.K. Resolution Authority (if such consent is then required by the Capital Regulations). In addition, any repurchase of Senior Debt Securities shall be subject to the additional conditions set out under “—Additional Conditions Relating to Redemption and Repurchase of Debt Securities – Senior Debt Securities” below.

We will treat as cancelled and no longer issued and outstanding any Senior Debt Securities of any series that we purchase beneficially for our own account, other than a purchase in the ordinary course of a business dealing in securities. Unless otherwise specified in the applicable prospectus supplement, you have no right to require us to repurchase the Senior Debt Securities. Such Senior Debt Securities will stop bearing interest on the redemption date, even if you do not collect your money.

Dated Subordinated Debt Securities

Unless the applicable prospectus supplement provides otherwise, we or any member of the Group may purchase or otherwise acquire any outstanding Dated Subordinated Debt Securities of any series at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations). In addition, any repurchase of Dated Subordinated Debt Securities shall be subject to the additional conditions set out under “—Additional Conditions Relating to Redemption and Repurchase of Debt Securities – Dated Subordinated Debt Securities” below.

We will treat as cancelled and no longer issued and outstanding any Dated Subordinated Debt Securities of any series that we purchase beneficially for our own account, other than a purchase in the ordinary course of a business dealing in securities. Unless otherwise specified in the applicable prospectus supplement, you have no right to require us to repurchase the Dated Subordinated Debt Securities. Such Dated Subordinated Debt Securities will stop bearing interest on the redemption date, even if you do not collect your money.

-17-

Additional Conditions Relating to Redemption and Repurchase of Debt Securities

Senior Debt Securities

Any early redemption or repurchase of a particular series of Senior Debt Securities shall be subject to one of the following conditions in (1), (2) or (3) below being met, as applicable to such Senior Debt Securities, in each case, if and to the extent then required by the Capital Regulations:

(1) before or at the same time as such redemption or repurchase of the Senior Debt Securities, we replace such Senior Debt Securities with “own funds instruments” or “eligible liabilities instruments” (each as defined below) of equal or higher quality at terms that are sustainable for our income capacity; or

(2) we have demonstrated to the satisfaction of the Relevant U.K. Resolution Authority that our “own funds” and “eligible liabilities” (each as defined below) would, following such redemption or repurchase, exceed the requirements for own funds and eligible liabilities laid down in U.K. CRD and in the U.K. legislation that implemented EU Directive 2014/59/EU, as amended from time to time, by a margin that the Relevant U.K. Resolution Authority, in agreement with the PRA, considers necessary; or

(3) we have demonstrated to the satisfaction of the Relevant U.K. Resolution Authority that the partial or full replacement of the Senior Debt Securities with own funds instruments is necessary to ensure compliance with the own funds requirements in U.K. CRD for continuing authorization.

Notwithstanding the conditions set out above, if, at the time of any such redemption or repurchase, the Capital Regulations permit the redemption or repurchase of a particular series of Senior Debt Securities only after compliance with one or more alternative or additional pre-conditions to those set out above, we will comply with such other and/or, as appropriate, additional pre-condition(s).

“eligible liabilities” has the meaning given to such term in the Banking Act and “eligible liabilities instruments” means eligible liabilities instruments for the purposes of the Capital Regulations.

“own funds” has the meaning given to such term in the U.K. CRD Regulation as interpreted and applied in accordance with the Capital Regulations. Under the U.K. CRD Regulation, as at the date hereof, “own funds” means the sum of Tier 1 Capital and Tier 2 Capital.

“own funds instruments” has the meaning given to such term in the U.K. CRD Regulation as interpreted and applied in accordance with the Capital Regulations. Under the U.K. CRD Regulation, as at the date hereof, “own funds instruments” means capital instruments issued by the institution that qualify as Common Equity Tier 1, Additional Tier 1 or Tier 2 instruments.

“Common Equity Tier 1, Additional Tier 1 or Tier 2 instruments” means Common Equity Tier 1, Additional Tier 1 or Tier 2 instruments, respectively, for purposes of the Capital Regulations.

Dated Subordinated Debt Securities

Any early redemption or repurchase of a particular series of Dated Subordinated Debt Securities shall be subject to:

(A) one of the following conditions in (1) or (2) below being met, as applicable to such Dated Subordinated Debt Securities, in each case, if and to the extent then required by the Capital Regulations:

(1) before or at the same time as such redemption or repurchase of the Dated Subordinated Debt Securities, we replace such Dated Subordinated Debt Securities with “own funds instruments” of equal or higher quality at terms that are sustainable for our income capacity; or

-18-

(2) we have demonstrated to the satisfaction of the PRA that our “own funds” and “eligible liabilities” would, following such redemption or repurchase, exceed the relevant requirements for our own funds and eligible liabilities laid down in U.K. CRD and in the U.K legislation that implemented EU Directive 2014/59/EU, as amended from time to time, by a margin that the PRA considers necessary.

(B) in the case of any such early redemption or repurchase of a particular series of Dated Subordinated Debt Securities before five years after the date of issuance of the relevant series of Dated Subordinated Debt Securities, one of the following conditions in (1), (2), (3) or (4) below being met, in each case, if and to the extent then required by the Capital Regulations:

(1) in the case of redemption due to the occurrence of a change in the regulatory classification of the relevant Dated Subordinated Debt Securities that does or would be likely to result in their exclusion from own funds or reclassification as own funds of lower quality (i) the PRA considers such change to be sufficiently certain and (ii) we demonstrate to the satisfaction of the PRA that such regulatory reclassification was not reasonably foreseeable at the time of the issuance of the relevant Dated Subordinated Debt Securities; or

(2) in the case of redemption due to the occurrence of a Tax Event, we demonstrate to the satisfaction of the PRA that such Tax Event is material and was not reasonably foreseeable at the time of issuance of the relevant Dated Subordinated Debt Securities; or

(3) before or at the same time as such redemption or repurchase of the relevant Dated Subordinated Debt Securities, we replace such Dated Subordinated Debt Securities with own funds instruments of equal or higher quality at terms that are sustainable for our income capacity and the PRA has permitted that action on the basis of the determination that it would be beneficial from a prudential point of view and justified by exceptional circumstances; or

(4) the relevant Dated Subordinated Debt Securities are repurchased for market making purposes.

Notwithstanding the conditions set out above, if, at the time of any such redemption or repurchase, the Capital Regulations permit the redemption or repurchase of a particular series of Dated Subordinated Debt Securities only after compliance with one or more alternative or additional pre-conditions to those set out above, we will comply with such other and/or, as appropriate, additional pre-condition(s).

Modification and Waiver

We and the trustee may make certain modifications and amendments to the indenture applicable to each series of debt securities without the consent of the holders of the debt securities. We may make other modifications and amendments with the consent of the holder(s) of not less than, in the case of the Senior Debt Securities, a majority of or, in the case of the Dated Subordinated Debt Securities, 66 2/3% in aggregate principal amount of the debt securities of the series outstanding under the applicable indenture that are affected by the modification or amendment. However, we may not make any modification or amendment without the consent of the holder of each affected debt security that would:

-19-

Unless the relevant prospectus supplement provides otherwise, in addition, any variations in the terms and conditions of Dated Subordinated Debt Securities of any series, including modifications relating to the subordination or redemption provisions of such Dated Subordinated Debt Securities, can only be made in accordance with the rules and requirements of the PRA, as and to the extent applicable from time to time.

Senior Enforcement Events and Remedies; Dated Subordinated Enforcement Events and Remedies; Limitation on Suits

Senior Enforcement Events and Remedies

Winding-up

Unless the relevant prospectus supplement provides otherwise, if a Senior Winding-up Event occurs, the outstanding principal amount of the Senior Debt Securities of any series together with any accrued but unpaid interest thereon will become immediately due and payable.

A “Senior Winding-up Event” with respect to the Senior Debt Securities of any series shall result if (i) a court of competent jurisdiction in England (or such other jurisdiction in which we may be organized) makes an order for our winding-up which is not successfully appealed within thirty (30) days of the making of such order, (ii) our shareholders adopt an effective resolution for our winding-up (other than, in the case of either (i) or (ii) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (iii) following the appointment of an administrator of the Issuer, the administrator gives notice that it intends to declare and distribute a dividend.

Non-payment

If we fail to pay any amount that has become due and payable under the Senior Debt Securities of the relevant series and such failure continues for fourteen (14) days, the trustee may give us notice of such failure. If within a period of fourteen (14) days following the provision of such notice, the failure continues and has not been cured nor waived (a “Senior Non-Payment Event”), the trustee may at its discretion and without further notice to us institute proceedings in England (or such other jurisdiction in which we may be organized) (but not elsewhere) for our winding-up and/or prove in our winding-up and/or claim in our liquidation or administration.

Limited remedies for breach of obligations (other than non-payment)

In addition to the remedies for non-payment provided above, the trustee may, without further notice, institute such proceedings against us as the trustee may deem fit to enforce any term, obligation or condition binding on us under the relevant series of Senior Debt Securities or the Senior Debt Securities Indenture (other than any payment obligation of the Issuer under or arising from the Senior Debt Securities of such series or the Senior Debt Securities Indenture, including, without limitation, payment of any principal or interest, including

-20-

Debt Security Additional Amounts) (such obligation, a “Senior Performance Obligation”); provided always that the trustee (acting on behalf of the holders of the Senior Debt Securities of such series) and the holders of such Senior Debt Securities may not enforce, and may not be entitled to enforce or otherwise claim, against us any judgment or other award given in such proceedings that requires the payment of money by us, whether by way of damages or otherwise (a “Senior Monetary Judgment”), except by proving such Senior Monetary Judgment in our winding-up and/or by claiming such Senior Monetary Judgment in our administration.

By its acquisition of the Senior Debt Securities of any series, each holder of such Senior Debt Securities acknowledges and agrees that such holder will not seek to enforce or otherwise claim, and will not direct the trustee (acting on behalf of the holders of such Senior Debt Securities) to enforce or otherwise claim, a Senior Monetary Judgment against us in connection with our breach of a Senior Performance Obligation, except by proving such Senior Monetary Judgment in our winding-up and/or by claiming such Senior Monetary Judgment in our administration.

No other remedies

Other than the limited remedies specified herein under “Senior Enforcement Events and Remedies” and subject to “—Trust Indenture Act remedies” below, no remedy against us will be available to the trustee (acting on behalf of the holders of the Senior Debt Securities of any series) or the holders of such Senior Debt Securities whether for the recovery of amounts owing in respect of such Senior Debt Securities or under the Senior Debt Securities Indenture or in respect of any breach by us of any of our obligations under or in respect of the terms of such Senior Debt Securities or under the Senior Debt Securities Indenture in relation thereto; provided, however, that such limitation shall not apply to our obligations to pay the fees and expenses of, and to indemnify, the trustee (including fees and expenses of trustee’s counsel).

Trust Indenture Act remedies

Notwithstanding the limitation on remedies specified herein under “Senior Enforcement Events and Remedies,” (1) the trustee will have such powers as are required to be authorized to it under the Trust Indenture Act in respect of the rights of the holders of the Senior Debt Securities of any series under the provisions of the Senior Debt Securities Indenture and (2) nothing shall impair the right of a holder of the Senior Debt Securities of any series under the Trust Indenture Act, absent such holder’s consent, to sue for any payment due but unpaid with respect to the relevant Senior Debt Securities. No holder of Senior Debt Securities of any series shall be entitled to proceed directly against us except as described below under “—Limitation on Suits.”

Under the terms of the Senior Debt Securities Indenture, the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Senior Debt Securities is not a Senior Enforcement Event.

Trustee’s Duties—Senior Debt Securities

In case of a Senior Enforcement Event under the Senior Debt Securities Indenture of which a responsible officer of the trustee shall have received written notice at the corporate trust office of the trustee, the trustee shall exercise such of the rights and powers vested in it by the Senior Debt Securities Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. For these purposes, a “Senior Enforcement Event” shall occur (i) upon the occurrence of a Senior Winding-up Event, (ii) upon the occurrence of a Senior Non-Payment Event or (iii) upon a breach by us of a Senior Performance Obligation with respect to the relevant series of the Senior Debt Securities. Holders of a majority of the aggregate principal amount of the outstanding Senior Debt Securities may waive any past Senior Enforcement Event specified in clause (iii) in the preceding sentence but may not waive any past Senior Enforcement Event specified in clauses (i) and (ii) in the preceding sentence.

If a Senior Enforcement Event occurs and is continuing with respect to the Senior Debt Securities of any series, the trustee will have no obligation to take any action at the direction of any holders of such series of the Senior Debt Securities, unless they have offered the trustee security or indemnity satisfactory to the trustee in its

-21-

sole discretion. Subject to the foregoing sentence, the holders of a majority in aggregate principal amount of the outstanding Senior Debt Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series of the Senior Debt Securities. However, this direction (a) must not be in conflict with any rule of law or the Senior Debt Securities Indenture and (b) must not be unjustly prejudicial to the holder(s) of such series of the Senior Debt Securities not taking part in the direction, in the case of either (a) or (b) as determined by the trustee in its sole discretion. The trustee may also take any other action, consistent with the direction, that it deems proper.

The trustee will, within ninety (90) days of a Senior Enforcement Event with respect to the Senior Debt Securities of any series, give to each affected holder of the Senior Debt Securities of the affected series notice of any Senior Enforcement Event known to the trustee, unless the Senior Enforcement Event has been cured or waived. However, the trustee will be entitled to withhold notice if a trust committee of responsible officers of the trustee determine in good faith that withholding of notice is in the interest of the holders.

We are required to furnish to the trustee annually a statement as to our compliance with all conditions and covenants under the Senior Debt Securities Indenture.

Dated Subordinated Enforcement Events and Remedies

Winding-up

Unless the relevant prospectus supplement provides otherwise, if a Dated Subordinated Winding-up Event occurs, the outstanding principal amount of the Dated Subordinated Debt Securities of any series together with any accrued but unpaid interest thereon will become immediately due and payable, subject to the subordination provisions described above under “—Ranking.”

A “Dated Subordinated Winding-up Event” with respect to the Dated Subordinated Debt Securities of any series shall result if (i) a court of competent jurisdiction in England (or such other jurisdiction in which we may be organized) makes an order for our winding-up which is not successfully appealed within thirty (30) days of the making of such order, (ii) our shareholders adopt an effective resolution for our winding-up (other than, in the case of either (i) or (ii) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (iii) following the appointment of an administrator of the Issuer, the administrator gives notice that it intends to declare and distribute a dividend.

Non-payment

If we fail to pay any amount that has become due and payable under the relevant Dated Subordinated Debt Securities and such failure continues for fourteen (14) days, the trustee may give us written notice of such failure.

If within a period of fourteen (14) days following the provision of such notice, the failure continues and has not been cured nor waived (a “Dated Subordinated Non-Payment Event”), the trustee may at its discretion and without further notice to us institute proceedings in England (or such other jurisdiction in which we may be organized) (but not elsewhere) for our winding-up and/or prove in our winding-up and/or claim in our liquidation or administration.

Limited remedies for breach of obligations (other than non-payment)

In addition to the remedies for non-payment provided above, the trustee may, without further notice, institute such proceedings against us as the trustee may deem fit to enforce any term, obligation or condition binding on us under the relevant Dated Subordinated Debt Securities or the Dated Subordinated Debt Securities Indenture (other than any payment obligation of the Issuer under or arising from such Dated Subordinated Debt Securities or the Dated Subordinated Debt Securities Indenture, including, without limitation, payment of any principal or interest, including Debt Security Additional Amounts) (such obligation, a “Dated Subordinated Performance Obligation”); provided always that the trustee (acting on behalf of the holders of such Dated

-22-

Subordinated Debt Securities) and the holders of such Dated Subordinated Debt Securities may not enforce, and may not be entitled to enforce or otherwise claim, against us any judgment or other award given in such proceedings that requires the payment of money by us, whether by way of damages or otherwise (a “Dated Subordinated Monetary Judgment”), except by proving such Dated Subordinated Monetary Judgment in our winding-up and/or by claiming such Dated Subordinated Monetary Judgment in our administration.

By its acquisition of the Dated Subordinated Debt Securities of any series, each holder of such Dated Subordinated Debt Securities acknowledges and agrees that such holder will not seek to enforce or otherwise claim, and will not direct the trustee (acting on behalf of the holders of such Dated Subordinated Debt Securities) to enforce or otherwise claim, a Dated Subordinated Monetary Judgment against us in connection with our breach of a Dated Subordinated Performance Obligation, except by proving such Dated Subordinated Monetary Judgment in our winding-up and/or by claiming such Dated Subordinated Monetary Judgment in our administration.

No other remedies

Other than the limited remedies specified herein under “Dated Subordinated Enforcement Events and Remedies” and subject to “—Trust Indenture Act remedies” below, no remedy against us will be available to the trustee (acting on behalf of the holders of the Dated Subordinated Debt Securities of any series) or the holders of such Dated Subordinated Debt Securities whether for the recovery of amounts owing in respect of such Dated Subordinated Debt Securities or under the Dated Subordinated Debt Securities Indenture or in respect of any breach by us of any of our obligations under or in respect of the terms of such Dated Subordinated Debt Securities or under the Dated Subordinated Debt Securities Indenture in relation thereto; provided, however, that such limitation shall not apply to our obligations to pay the fees and expenses of, and to indemnify, the trustee (including fees and expenses of trustee’s counsel) and the trustee’s rights to apply money collected to first pay its fees and expenses shall not be subject to the subordination provisions set forth in the Dated Subordinated Debt Securities Indenture and any subordination provision in any supplemental indenture thereto.

Trust Indenture Act remedies

Notwithstanding the limitation on remedies specified herein under “Dated Subordinated Enforcement Events and Remedies,” (1) the trustee will have such powers as are required to be authorized to it under the Trust Indenture Act in respect of the rights of the holders of the Dated Subordinated Debt Securities of any series under the provisions of the Dated Subordinated Debt Securities Indenture and (2) nothing shall impair the right of a holder of the Dated Subordinated Debt Securities of any series under the Trust Indenture Act, absent such holder’s consent, to sue for any payment due but unpaid with respect to the relevant Dated Subordinated Debt Securities; provided that, in the case of each of (1) and (2) above, any payments in respect of, or arising from, the Dated Subordinated Debt Securities of any series, including any payments or amounts resulting or arising from the enforcement of any rights under the Trust Indenture Act in respect of such Dated Subordinated Debt Securities, are subject to the subordination provisions set forth in the Dated Subordinated Debt Securities Indenture and any subordination provisions in any supplemental indenture thereto.

Under the terms of the Dated Subordinated Debt Securities Indenture, the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Dated Subordinated Debt Securities is not a Dated Subordinated Enforcement Event.

Trustee’s Duties—Dated Subordinated Debt Securities

In case of a Dated Subordinated Enforcement Event under any series of the Dated Subordinated Debt Securities, the trustee shall exercise such of the rights and powers vested in it by the Dated Subordinated Debt Securities Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. For these purposes, a “Dated Subordinated Enforcement Event” shall occur (i) upon the occurrence of Dated Subordinated Winding-up Event, (ii) upon the occurrence of a Dated Subordinated Non-Payment Event or (iii) upon a breach by us of a Dated

-23-

Subordinated Performance Obligation with respect to the relevant series of the Dated Subordinated Debt Securities. Holders of a majority of the aggregate principal amount of the outstanding Dated Subordinated Debt Securities of a series may waive any past Dated Subordinated Enforcement Event specified in clause (iii) in the preceding sentence but may not waive any past Dated Subordinated Enforcement Event specified in clauses (i) and (ii) in the preceding sentence.

If a Dated Subordinated Enforcement Event occurs and is continuing with respect to any series of the Dated Subordinated Debt Securities, the trustee will have no obligation to take any action at the direction of any holders of such series of the Dated Subordinated Debt Securities, unless they have offered the trustee security or indemnity satisfactory to the trustee in its sole discretion. The holders of a majority in aggregate principal amount of the outstanding Dated Subordinated Debt Securities of a series shall have the right to direct the time, method and place of conducting any proceeding in the name of and on the behalf of the trustee for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series of the Dated Subordinated Debt Securities. However, this direction (a) must not be in conflict with any rule of law or the Dated Subordinated Debt Securities Indenture and (b) must not be unjustly prejudicial to the holder(s) of such series of the Dated Subordinated Debt Securities not taking part in the direction, in the case of either (a) or (b) as determined by the trustee in its sole discretion. The trustee may also take any other action, consistent with the direction, that it deems proper.

The trustee will, within ninety (90) days of a Dated Subordinated Enforcement Event with respect to the Dated Subordinated Debt Securities of any series, give to each affected holder of the Dated Subordinated Debt Securities of the affected series notice of any Dated Subordinated Enforcement Event known to the trustee, unless the Dated Subordinated Enforcement Event has been cured or waived. However, the trustee will be entitled to withhold notice if a trust committee of responsible officers of the trustee determine in good faith that withholding of notice is in the interest of the holders.

We are required to furnish to the trustee annually a statement as to our compliance with all conditions and covenants under the Dated Subordinated Debt Securities Indenture.

Limitation on Suits

Before a holder of debt securities may bypass the trustee and bring its own lawsuit or other formal legal action or take other steps to enforce its rights or protect its interests relating to the debt securities, the following must occur:

Notwithstanding any contrary provisions, nothing shall impair the right of a holder, absent the holder’s consent, to sue for any payments due but unpaid with respect to the debt securities.

-24-

Street name and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to waive any past Senior Enforcement Event or Dated Subordinated Enforcement Event, as applicable, as described below in “Description of Certain Provisions Relating to Debt Securities and Contingent Capital Securities—Legal Ownership; Form of Securities.”

Consolidation, Merger and Sale of Assets; Assumption

We may, without the consent of the holders of any of the debt securities, consolidate or amalgamate with, merge into or transfer or lease our assets substantially as an entirety to, any person of the persons specified in the applicable indenture. However, any successor person formed by any consolidation, amalgamation or merger, or any transferee or lessee of our assets, must assume our obligations on the debt securities and the applicable indenture, and a number of other conditions must be met.

Subject to applicable law and regulation (and if and to the extent required by the Capital Regulations at such time, the prior consent of the PRA and/or the Relevant U.K. Resolution Authority in the case of the Dated Subordinated Debt Securities or the Relevant U.K. Resolution Authority in the case of the Senior Debt Securities), any of our wholly owned subsidiaries may assume our obligations under the debt securities of any series without the consent of any holder. We, however, must irrevocably guarantee (on a subordinated basis in substantially the manner described under “—Ranking—Dated Subordinated Debt Securities” above, in the case of Dated Subordinated Debt Securities) the obligations of the subsidiary under the debt securities of that series. If we do, all of our direct obligations under the debt securities of the series and the applicable indenture shall immediately be discharged. Unless the relevant prospectus supplement provides otherwise, any Debt Security Additional Amounts under the debt securities of the series will be payable in respect of Taxes imposed by the jurisdiction in which the successor entity is organized, rather than Taxes imposed by a U.K. Taxing Jurisdiction, subject to exceptions equivalent to those that apply to any obligation to pay Debt Security Additional Amounts in respect of Taxes imposed by a U.K. Taxing Jurisdiction. However, if we make payment under this guarantee, we shall also be required to pay Debt Security Additional Amounts related to taxes (subject to the exceptions set forth in “—Payment of Debt Security Additional Amounts” above) imposed by a U.K. Taxing Jurisdiction due to this guarantee payment. A subsidiary that assumes our obligations will also be entitled to redeem the debt securities of the relevant series in the circumstances described under “—Redemption” above with respect to any change or amendment to, or change in the official application of the laws or regulations (including any treaty) of the assuming corporation’s jurisdiction of incorporation as long as the change or amendment occurs after the date of the subsidiary’s assumption of our obligations.

The U.S. Internal Revenue Service (the “IRS”) might deem an assumption of our obligations as described above to be an exchange of the existing debt securities for new debt securities, resulting in a recognition of taxable gain or loss and possibly other adverse tax consequences. Investors should consult their tax advisors regarding the tax consequences of such an assumption.

Governing Law

Unless the applicable prospectus supplement provides otherwise, the debt securities, the Senior Debt Securities Indenture and the Dated Subordinated Debt Securities Indenture will be governed by and construed in accordance with the laws of the State of New York, except that, as specified in the relevant indenture, any applicable subordination provisions of each series of Dated Subordinated Debt Securities and any applicable provisions relating to waiver of set-off of each series of debt securities and the related provisions in the relevant indenture will be governed by and construed in accordance with English law.

Notices

Notices regarding the debt securities will be valid:

-25-

With respect to a global debt security representing any series of debt securities, a copy of all notices with respect to such series will be delivered to the depositary for such global debt security.

The Trustee

The Bank of New York Mellon acting through its London Branch, will be the trustee under the indentures. The trustee has two principal functions:

We and some of our subsidiaries maintain deposit accounts and conduct other banking transactions with the trustee in the ordinary course of our respective businesses.

Consent to Service

The indentures provide that we irrevocably designate Barclays Bank PLC (New York Branch), 745 Seventh Avenue, New York, New York 10019, Attention: General Counsel as our authorized agent for service of process in any proceeding arising out of or relating to the Senior Debt Securities Indenture or Dated Subordinated Debt Securities Indenture, as applicable, or debt securities brought in any federal or state court in the Borough of Manhattan, the City of New York, and we irrevocably submit to the jurisdiction of these courts.

DESCRIPTION OF CONTINGENT CAPITAL SECURITIES

The following is a summary of the general terms of the contingent capital securities (as defined below). It sets forth possible terms and provisions for each series of contingent capital securities. Each time that we offer contingent capital securities, we will prepare and file a prospectus supplement with the SEC, which you should read carefully. The prospectus supplement may contain additional terms and provisions of those contingent capital securities. If there is any inconsistency between the terms and provisions presented here and those in the prospectus supplement, those in the prospectus supplement will apply and will replace those presented here.

As used in this prospectus, “contingent capital securities” means the subordinated securities of Barclays PLC which may be convertible into ordinary shares of Barclays PLC or which may be permanently written down to zero that the trustee authenticates and delivers under the applicable indenture. The contingent capital securities will not be secured by any assets or property of Barclays PLC or any of its subsidiaries or affiliates (including Barclays Bank PLC, its subsidiary).

Contingent capital securities will be issued in one or more series under the Contingent Capital Securities Indenture dated as of August 14, 2018, among us, The Bank of New York Mellon, London Branch, as trustee and The Bank of New York Mellon SA/NV, Luxembourg Branch, as contingent capital security registrar (as heretofore supplemented and amended, the “Contingent Capital Securities Indenture”). The terms of the contingent capital securities include those stated in the Contingent Capital Securities Indenture and any supplements thereto, and those terms made part of the Contingent Capital Securities Indenture by reference to the Trust Indenture Act. We have filed the Contingent Capital Securities Indenture as an exhibit to the registration statement of which this prospectus is a part.

Because this section is a summary, it does not describe every aspect of the contingent capital securities in detail. This summary is subject to, and qualified by reference to, all of the definitions and provisions of the Contingent Capital Securities Indenture, any supplement to the Contingent Capital Securities Indenture and the form of the instrument representing each series of contingent capital securities. Certain terms, unless otherwise defined here, have the meaning given to them in the Contingent Capital Securities Indenture.

References to “you” and “holder” in the subsections to this section “Description of Contingent Capital Securities,” entitled “—Interest Cancellation,” “—Ranking of Contingent Capital Securities,” “—No Set-off,” “—Agreement with Respect to the Exercise of U.K. Bail-in Power,” “—Subsequent Holders’ Agreement,” “—Payment of Contingent Capital Additional Amounts,” “—Contingent Capital Enforcement Events and Remedies—Limited remedies for breach of obligations (other than non-payment)” and “—Contingent Capital Enforcement Events and Remedies—No other remedies” below, include beneficial owners of the contingent capital securities.

General

The contingent capital securities are not deposit liabilities of Barclays PLC and are not insured by any regulatory body of the United States or the United Kingdom.

Because we are a holding company, our rights to participate in the assets of any of our subsidiaries upon its liquidation will be subject to the prior claims of the subsidiaries’ creditors, including, in the case of our bank subsidiaries, their respective depositors, except, in our case, to the extent that we may ourselves be a creditor with recognized claims against the relevant subsidiary.

The Contingent Capital Securities Indenture does not limit the amount of contingent capital securities that we may issue. We may issue the contingent capital securities in one or more series, or as units comprised of two or more related series. A series of contingent capital securities will be perpetual (i.e., without a maturity date).

-27-

The prospectus supplement will indicate for each series or of two or more related series of contingent capital securities:

-28-

The prospectus supplement relating to any series of contingent capital securities may also include, if applicable, a discussion of certain U.S. federal income tax considerations and considerations under the Employee Retirement Income Security Act of 1974, as amended.

-29-

If we issue contingent capital securities in bearer form, the special restrictions and considerations relating to such bearer contingent capital securities, including applicable offering restrictions and U.S. tax considerations, will be described in the relevant prospectus supplement.

Contingent capital securities may bear interest at a fixed rate or a floating rate or we may issue contingent capital securities that bear no interest or that bear interest at a rate below the prevailing market interest rate.

Holders of contingent capital securities have no voting rights except as explained in this section below under “—Modification and Waiver,” “—Contingent Capital Enforcement Events and Remedies,” “—Trustee’s Duties” and “—Limitation on Suits.”

If we issue contingent capital securities that qualify as Tier 1 Capital or other regulatory capital securities for the purposes of the Capital Regulations, the terms may vary from those described in this prospectus and will be set forth in the accompanying prospectus supplement.

Market-Making Transactions. If you purchase your contingent capital security in a market-making transaction, you will receive information about the price you pay and your trade and settlement dates in a separate confirmation of sale. A market-making transaction is one in which Barclays Capital Inc. or another of our affiliates resells a security that it has previously acquired from another holder. A market-making transaction in a particular contingent capital security occurs after the original issuance and sale of the contingent capital security.

Payments

The relevant prospectus supplement will specify the date on which we will pay interest, if any, the date, if any, for payments of principal and any premium, if any, on any particular series of contingent capital securities. The prospectus supplement will also specify the interest rate or rates, if any, or how the rate or rates will be calculated.

Interest Cancellation

Interest Payments Discretionary

Unless the relevant prospectus supplement provides otherwise, interest on the contingent capital securities will be due and payable only at the sole discretion of the Issuer, and the Issuer shall have sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any interest payment date. If the Issuer does not make an interest payment on the relevant interest payment date (or if the Issuer elects to make a payment of a portion, but not all, of such interest payment), such non-payment shall evidence the Issuer’s exercise of its discretion to cancel such interest payment (or the portion of such interest payment not paid), and accordingly such interest payment (or the portion thereof not paid) shall not be due and payable.

If the Issuer provides notice to cancel a portion, but not all, of an interest payment and the Issuer subsequently does not make a payment of the remaining portion of such interest payment on the relevant interest payment date, such non-payment shall evidence the Issuer’s exercise of its discretion to cancel such remaining portion of the interest payment, and accordingly such remaining portion of the interest payment shall also not be due and payable.

Because the contingent capital securities are intended to qualify in whole or in part as Additional Tier 1 Capital under U.K. CRD, the Issuer may cancel (in whole or in part) any interest payment at its discretion and may pay dividends on its ordinary or preference shares notwithstanding such cancellation. In addition, the Issuer may use such cancelled payments without restriction to meet its obligations as they fall due.

See also “—Agreement to Interest Cancellation,” “—Notice of Interest Cancellation” and “—Interest Cancellation Following a Contingent Capital Regulatory Event” below.

Restriction on Interest Payments

Unless the relevant prospectus supplement provides otherwise, subject to the extent permitted in the following paragraph in respect of partial interest payments, the Issuer shall not make an interest payment on the relevant series of contingent capital securities on any interest payment date (and such interest payment shall therefore be deemed to have been cancelled and thus shall not be due and payable on such interest payment date) if:

(a) the Issuer has an amount of Distributable Items on such interest payment date that is less than the sum of (i) all distributions or interest payments made or declared by the Issuer since the end of the last financial year and prior to such interest payment date on or in respect of any Parity Securities, the relevant series of contingent capital securities and any Junior Securities and (ii) all distributions or interest payments payable by the Issuer (and not cancelled or deemed cancelled) on such interest payment date (x) on the relevant series of contingent capital securities and (y) on or in respect of any Parity Securities, in the case of each of (i) and (ii), excluding any payments already accounted for in determining the Distributable Items; or

(b) the Solvency Condition (as defined under “—Ranking of Contingent Capital Securities” below) is not satisfied in respect of such interest payment.

The Issuer may, in its sole discretion, elect to make a partial interest payment on the relevant series of contingent capital securities on any interest payment date, only to the extent that such partial interest payment may be made without breaching the restriction in the preceding paragraph.

The Issuer will be responsible for determining compliance with this restriction on interest payments and neither the trustee nor any agent shall be required to monitor such compliance or to perform any calculations in connection therewith.

“Distributable Items” shall have the meaning assigned to such term in the Capital Regulations, but amended so that for so long as there is any reference therein to “before distributions to holders of own funds instruments” it shall be read as a reference to “before distributions to holders of Parity Securities, the contingent capital securities or any Junior Securities.” Under U.K. CRD, as at the date hereof, “distributable items” means the amount of the profits at the end of the last financial year plus any profits brought forward and reserves available for that purpose before distributions to holders of own funds instruments less any losses brought forward, any profits which are non-distributable pursuant to the law of the United Kingdom, or any part of it, or of a third country or the institution’s by-laws and any sums placed to non-distributable reserves in accordance with the law of the United Kingdom, or any part of it, or of a third country or the statutes of the institution, in each case with respect to the specific category of own fund instruments to which the law of the United Kingdom, or any part of it, or of a third country or the institution’s by-laws or statutes relate, such profits, losses and reserves being determined on the basis of the individual accounts of the institution and not on the basis of the consolidated accounts.

“Junior Securities” means any ordinary shares, securities or other obligations (including any guarantee, credit support or similar undertaking) of the Issuer ranking, or expressed to rank, junior to the relevant series of contingent capital securities in a winding-up or administration of the Issuer.

“Parity Securities” means any preference shares, securities or other obligations (including any guarantee, credit support or similar undertaking) of the Issuer ranking, or expressed to rank, pari passu with the relevant series of contingent capital securities in a winding-up or administration of the Issuer.
