PROSPECTUS SUPPLEMENT

(To prospectus dated February 23, 2024)

HSBC Holdings plc

$1,350,000,000 6.875% Perpetual Subordinated Contingent Convertible Securities

(Callable During Any 2030 Securities Optional Redemption Period)

$1,150,000,000 6.950% Perpetual Subordinated Contingent Convertible Securities

(Callable During Any 2034 Securities Optional Redemption Period)

We are offering $1,350,000,000 principal amount of 6.875% Perpetual Subordinated Contingent Convertible Securities (Callable During Any 2030 Securities Optional Redemption Period) (such series of securities, the “2030 Securities”) and $1,150,000,000 principal amount of 6.950% Perpetual Subordinated Contingent Convertible Securities (Callable During Any 2034 Securities Optional Redemption Period) (such series, the “2034 Securities”). The Securities (as defined below) will be issued pursuant to the indenture dated August 1, 2014 (as amended and supplemented from time to time), as amended and supplemented by a fifteenth supplemental indenture, with respect to the 2030 Securities, and a sixteenth supplemental indenture, with respect to the 2034 Securities, both of which are expected to be entered into on September 11, 2024 (together with the fifteenth supplemental indenture or the sixteenth supplemental indenture, as applicable, the “Indenture”). The “Securities” means either the 2030 Securities or the 2034 Securities, or both of them together, as applicable.

From (and including) September 11, 2024 (the “Issue Date”) to (but excluding) March 11, 2030 (such date and each fifth anniversary date thereafter, a “2030 Securities Reset Date”), the interest rate on the 2030 Securities will be 6.875% per annum. From and including each 2030 Securities Reset Date to (but excluding) the next following 2030 Securities Reset Date, the applicable per annum interest rate will be equal to the sum of the applicable Reference Rate on the relevant Reset Determination Date and 3.298%. Subject to cancellation as described further below, we will pay interest on the 2030 Securities, if any, in arrear on March 11 and September 11 of each year, beginning on March 11, 2025.

From (and including) the Issue Date to (but excluding) September 11, 2034 (such date and each fifth anniversary date thereafter, a “2034 Securities Reset Date”), the interest rate on the 2034 Securities will be 6.950% per annum. From and including each 2034 Securities Reset Date to (but excluding) the next following 2034 Securities Reset Date, the applicable per annum interest rate will be equal to the sum of the applicable Reference Rate on the relevant Reset Determination Date and 3.191%. Subject to cancellation as described further below, we will pay interest on the 2034 Securities, if any, in arrear on March 11 and September 11 of each year, beginning on March 11, 2025.

The interest rate following any Reset Date (as defined below) may be less than the interest rate that applies immediately prior to such Reset Date, including the initial interest rate of 6.875% for the 2030 Securities and 6.950% for the 2034 Securities. Moreover, interest will be due and payable on an interest payment date only to the extent it is not cancelled or deemed to have been cancelled in accordance with the terms of the Securities. We will 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. The terms of the Securities also provide for circumstances under which we will be restricted from making an interest payment (in whole or in part) on an interest payment date, and the interest payable in respect of any such interest payment date will be deemed to have been cancelled (in whole or in part). A “Reset Date” means either a 2030 Securities Reset Date or a 2034 Securities Reset Date, as applicable.

The Securities are perpetual and have no fixed maturity or fixed redemption date. As a result, you may not receive any payments with respect to the Securities as we are not required to pay the principal amount of the Securities at any time prior to a Winding-up Event and we will have the sole and absolute discretion at all times and for any reason to cancel in whole any interest payment.

We may redeem the 2030 Securities in our sole discretion in whole (but not in part) at 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption (excluding any cancelled or deemed to have been cancelled interest) during any 2030 Securities Optional Redemption Period (as defined below). We may redeem the 2034 Securities in our sole discretion in whole (but not in part) at 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption (excluding any cancelled or deemed to have been cancelled interest) during any 2034 Securities Optional Redemption Period (as defined below). Moreover, we may redeem the Securities upon the occurrence of certain tax and regulatory events as described in this prospectus supplement under “Description of the Securities—Redemption—Special Event Redemption.” Any redemption of the Securities is subject to the restrictions described in this prospectus supplement under “Description of the Securities—Redemption—Redemption Conditions.”

If a Capital Adequacy Trigger Event occurs, then an Automatic Conversion will occur without delay (but no later than one month following the date on which it is determined such Capital Adequacy Trigger Event has occurred), at which point all of our obligations under the Securities will be released irrevocably and automatically in consideration of our issuance of Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date, and under no circumstances will such released obligations be reinstated. On the Settlement Date, we expect the Conversion Shares Depository to deliver to the securityholders either (i) Conversion Shares (based on the Conversion Price) or (ii) if we elect, in our sole and absolute discretion, that a Conversion Shares Offer be made, the Conversion Shares Offer Consideration (consisting of the pro rata share of cash proceeds from the sale of any Conversion Shares pursuant to the Conversion Shares Offer (based on the Conversion Shares Offer Price) and the pro rata share of any Conversion Shares not sold pursuant to the Conversion Shares Offer (based on the Conversion Price)). The realizable value of any Conversion Shares received by a securityholder following an Automatic Conversion may be significantly less than the initial Conversion Price of $3.550 and/or the U.S. dollar equivalent of the initial Conversion Shares Offer Price of £2.70 per Conversion Share, and the securityholders could lose all or part of their investment in the Securities as a result of the Automatic Conversion.

By its acquisition of the Securities, among other things, each securityholder (which, for these purposes, includes each beneficial owner) will (i) acknowledge and agree that interest is payable solely at our discretion and no amount of interest will become due and payable in respect of the relevant interest period to the extent that it has been (x) cancelled (in whole or in part) by us at our sole discretion and/or (y) deemed to have been cancelled (in whole or in part), (ii) consent to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic Conversion following a Capital Adequacy Trigger Event and (y) the appointment of the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities), the issuance of the Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (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 and (iii) acknowledge and agree that effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of our winding-up or the appointment of an administrator for our administration as described in this prospectus supplement, no securityholder will have any rights against us with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on or in respect of such Securities, in each case that is not due and payable, which liabilities will be automatically released.

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge, accept, consent and agree, notwithstanding any other term of the Securities, the Indenture or any other agreements, arrangements or understandings between us and any securityholder, to be bound by (a) the effect of the exercise of any UK bail-in power (as defined herein) by the relevant UK resolution authority (as defined herein); and (b) the variation of the terms of the Securities or the Indenture, if necessary, to give effect to the exercise of any UK bail-in power by the relevant UK resolution authority. No repayment or payment of Amounts Due will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise. For these purposes, “Amounts Due” are the principal amount of, and any accrued and unpaid interest, including any Additional Amounts, on, the Securities. References to such amounts will include amounts that have become due and payable, but which have not been paid, prior to the exercise of any UK bail-in power by the relevant UK resolution authority. See “Description of the Securities—Agreement with Respect to the Exercise of UK Bail-in Power.” Moreover, each securityholder (which, for these purposes, includes each beneficial owner) will consent to the exercise of the UK bail-in power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to the Securities.

For the avoidance of doubt, the potential conversion of the Securities into shares, other securities or other obligations in connection with the exercise of any UK bail-in power by the relevant UK resolution authority is separate and distinct from an Automatic Conversion following a Capital Adequacy Trigger Event.

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner), to the extent permitted by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), will waive any and all claims, in law and/or in equity, against The Bank of New York Mellon, London Branch, as trustee, for, agree not to initiate a suit against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities.

Application has been made to The Irish Stock Exchange plc trading as Euronext Dublin (“Euronext Dublin”) for the approval of this document as listing particulars. Application has been made to Euronext Dublin for the Securities to be admitted to the Official List and to trading on the Global Exchange Market of Euronext Dublin (the “GEM”). The GEM is not a regulated market for the purposes of Directive 2014/65/EU (as amended, “MiFID II”) or Regulation (EU) No 600/2014 as it forms part of domestic law of the United Kingdom (“UK”) by virtue of the European Union (Withdrawal) Act 2018, as amended (the “EUWA”) (“UK MiFIR”). Admission to the Official List and trading on the GEM is expected to begin within 30 days of the initial delivery of the Securities.

The Securities are not deposit liabilities of HSBC Holdings and are not covered by the United Kingdom Financial Services Compensation Scheme or insured by the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the UK, the United States or any other jurisdiction. Investing in the Securities involves certain risks. See “Risk Factors” beginning on Page S-28.

Pursuant to the UK 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 UK.

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 MiFID II; or (ii) a customer within the meaning of Directive (EU) 2016/97 (the “IDD”), 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—UK PRIIPs REGULATION / PROHIBITION OF SALES TO UK 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 UK. 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 UK domestic law by virtue of the EUWA; or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000, as amended (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 UK domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of UK domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Securities or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

Prospective investors are referred to the sections headed “PRIIPs Regulation—Prohibition of sales to EEA retail investors” and “UK PRIIPs Regulation—Prohibition of sales to UK retail investors” on page S-3 of this prospectus supplement.

Unless otherwise defined, terms that are defined in “Description of the Securities” beginning on page S-57 have the same meaning when used on this cover page.

Neither the Securities and Exchange Commission (the “SEC”) nor any other regulatory body has approved or disapproved of these Securities or passed upon the adequacy or accuracy of this prospectus supplement or the related prospectus. Any representation to the contrary is a criminal offense.

We may use this prospectus supplement and the accompanying prospectus in the initial sale of the Securities. In addition, HSBC Securities (USA) Inc.

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 IDD, 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.

UK PRIIPS Regulation—Prohibition of sales to UK 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 UK. 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 UK domestic law by virtue of the EUWA; (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 UK domestic law by virtue of the EUWA. Consequently, no key information document required by the UK PRIIPs Regulation for offering or selling the Securities or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

We are responsible for the information contained and incorporated by reference in this prospectus supplement, the accompanying prospectus and in any related free-writing prospectus we prepare or authorize. We have not authorized anyone to give you any other information, and we take no responsibility for any other information that others may give you.

In connection with the issue of the Securities, HSI as the stabilization manager (or any person acting on behalf of it) may, to the extent permitted by laws or regulations, over-allot the Securities or effect transactions with a view to supporting the market price of the Securities at a level higher than that which might otherwise prevail. However, stabilization may not necessarily occur. Any stabilization action may begin on or after the date on which adequate public disclosure of the terms of the offer of the Securities is made and, if begun, may cease at any time, but it must end no later than the earlier of 30 days after the Issue Date and 60 days after the date of the allotment of the Securities. Any stabilization action or over-allotment must be conducted by HSI as the relevant stabilization manager (or any person acting on behalf of it) in accordance with all applicable laws and rules.

Important Notice to Prospective Investors Pursuant to Paragraph 21 of the Hong Kong SFC Code of Conduct

Prospective investors should be aware that certain intermediaries in the context of this offering of the Securities, including certain underwriters, are “capital market intermediaries” (“CMIs”) subject to Paragraph 21 of the Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (the “SFC Code”). This notice to prospective investors is a summary of certain obligations the SFC Code imposes on such CMIs, which require the attention and cooperation of prospective investors. Certain CMIs may also be acting as “overall coordinators” (“OCs”) for this offering and are subject to additional requirements under the SFC Code.

Prospective investors who are the directors, employees or major shareholders of HSBC Holdings, a CMI or its group companies would be considered under the SFC Code as having an association (“Association”) with HSBC Holdings, the CMI or the relevant group company. Prospective investors associated with HSBC Holdings or any CMI (including its group companies) should specifically disclose this when placing an order for the Securities and should disclose, at the same time, if such orders may negatively impact the price discovery process in relation to this offering. Prospective investors who do not disclose their Associations are hereby deemed not to be so associated. Where prospective investors disclose their Associations but do not disclose that such order may negatively impact the price discovery process in relation to this offering, such order is hereby deemed not to negatively impact the price discovery process in relation to this offering.

Prospective investors should ensure, and by placing an order prospective investors are deemed to confirm, that orders placed are bona fide, are not inflated and do not constitute duplicated orders (i.e. two or more corresponding or identical orders placed via two or more CMIs). If a prospective investor is an asset management arm affiliated with any underwriter, such prospective investor should indicate when placing an order if it is for a fund or portfolio where the underwriter or its group company has more than 50% interest, in which case it will be classified as a “proprietary order” and subject to appropriate handling by CMIs in accordance with the SFC Code and should disclose, at the same time, if such “proprietary order” may negatively impact the price discovery process in relation to this offering. Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. If a prospective investor is otherwise affiliated with any underwriter, such that its order may be considered to be a “proprietary order” (pursuant to the SFC Code), such prospective investor should indicate to the relevant underwriter when placing such order. Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. Where prospective investors disclose such information but do not disclose that such “proprietary order” may negatively impact the price discovery process in relation to this offering, such “proprietary order” is hereby deemed not to negatively impact the price discovery process in relation to this offering.

Prospective investors should be aware that certain information may be disclosed by CMIs (including private banks) which is personal and/or confidential in nature to the prospective investor. By placing an order, prospective investors are deemed to have understood and consented to the collection, disclosure, use and transfer of such information by the underwriter and/or any other third parties as may be required by the SFC Code, including to HSBC Holdings, any OCs, relevant regulators and/or any other third parties as may be required by

the SFC Code, it being understood and agreed that such information shall only be used for the purpose of complying with the SFC Code, during the bookbuilding process for this offering. Failure to provide such information may result in that order being rejected.

We are an English public limited company. Most of our directors and executive officers (and certain experts named in this prospectus supplement and the accompanying prospectus or in documents incorporated herein by reference) are resident outside the United States, and a substantial portion of our assets and the assets of such persons are located outside the United States. As a result, it may not be possible for you to effect service of process within the United States upon these persons or to enforce against them or us in U.S. courts judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by our English solicitors, Cleary Gottlieb Steen & Hamilton LLP, that there is doubt as to enforceability in the English courts, in original actions or in actions for enforcement of judgments of U.S. courts, of liabilities predicated solely upon the federal securities laws of the United States. In addition, awards of punitive damages in actions brought in the United States or elsewhere may not be enforceable in the UK. The enforceability of any judgment in the UK will depend on the particular facts of the case in effect at the time.

RISK FACTORS

An investment in the Securities involves significant risk. Accordingly, you should consider carefully all of the information set forth in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus, before you decide to invest in the Securities. Terms which are defined in “Description of the Securities” included in this prospectus supplement beginning on page S-57 have the same meaning when used in this section.

Risks Relating to HSBC’s Business

For information on risks relating to HSBC’s business, you should read the risks described in the 2023 Form 20-F, including the section entitled “Risk factors” on pages 168 through 180, Note 28 (Provisions) and Note 36 (Legal proceedings and regulatory matters) to the consolidated financial statements included therein on pages 432 through 433 and 444 through 447, respectively, and the risks described in the 2024 Interim Report, including the section entitled “Risk” on pages 62 through 109, Note 11 (Provisions) and Note 13 (Legal proceedings and regulatory matters) to the interim condensed consolidated financial statements included therein on page 131 and on pages 132 through 135, respectively, which are incorporated by reference in this prospectus supplement, and/or similar disclosure in subsequent filings incorporated by reference in this prospectus supplement.

Risks Relating to the Securities

The Securities have no fixed maturity and no fixed redemption date and you do not have the right to accelerate the repayment of the principal amount of the Securities prior to a Winding-up Event.

The Securities are perpetual securities and have no fixed maturity date or fixed redemption date. Moreover, 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 prior to a Winding-up Event (as described under “Description of the Securities—Default and Remedies”). Accordingly, we are under no obligation to repay or redeem (in whole or in part) the principal amount of the Securities at any time prior to such Winding-up Event and, as a result, you may not receive any payments of principal on the Securities.

Interest on the Securities will be due and payable on an interest payment date only if it is not cancelled or deemed to have been cancelled, and we may cancel interest (in whole or in part), in our absolute and sole discretion, at any time.

Interest will be due and payable only on an interest payment date to the extent it is not cancelled or deemed to have been cancelled in accordance with the terms of the Securities. Although we may, in our sole discretion, elect to make a partial interest payment on the Securities on any interest payment date, we may do so only to the extent that such partial interest payment may be made without breaching the restriction described below. Moreover, any portion of interest not paid on the relevant interest payment date will be deemed to have been cancelled.

We will 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 we do not make an interest payment in respect of the Securities on the relevant interest payment date (or if we elect to make a payment of a portion, but not all, of such interest payment), such non-payment will evidence the exercise of our 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) will not be due and payable. Moreover, notwithstanding such cancellation or that the Securities rank senior to our ordinary shares, we may use funds that could have been applied to make such cancelled interest payments to pay dividends on our ordinary or preference shares or to meet our other obligations as they become due, including on any Parity Securities (such as any other series of contingent convertible securities we may issue under the Indenture). It is the current intention of our board of

S-28

directors to take into account the relative ranking in our capital structure of our ordinary shares and outstanding additional Tier 1 securities whenever exercising its discretion to declare dividends on the former or to cancel interest on the latter. However, our board of directors may depart from this policy at any time in its sole discretion.

In addition, we will not make an interest payment on any interest payment date, and such interest payment will therefore be deemed to have been cancelled (and thus will not be due and payable on such interest payment date), if:

Interest will not be due and will not accumulate or be payable at any time after cancellation or deemed cancellation, and you will have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation. Furthermore, no cancellation or deemed cancellation of interest in accordance with the terms of the Indenture will constitute a default in payment or otherwise under the terms of the Securities. Although we will endeavor to provide notice of cancellation or deemed cancellation at least five business days prior to the relevant interest payment date, we will only do so if practicable, and failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed cancellation of interest.

Existing or new capital or leverage requirements may result in restrictions on making interest payments in respect of the Securities, in which case interest payments will be cancelled, which you may not be able to anticipate.

The capital and leverage frameworks (detailed below) to which we are subject require us to hold certain levels of capital, including common equity Tier 1 capital. A failure to hold sufficient levels of capital, including common equity Tier 1 capital, as required by these frameworks (as may be amended from time to time) may result in restrictions on distributions being applied pursuant to which we may be required to cancel (in whole or in part) interest payments in respect of the Securities. Cancellation (in whole or in part) of interest payments in respect of the Securities may affect the value of your investment in the Securities.

We are required, on a consolidated basis, to hold a minimum amount of total regulatory capital of 8% of risk weighted assets, a minimum amount of Tier 1 capital of 6% of risk weighted assets and a minimum amount of common equity Tier 1 capital of 4.5% of risk weighted assets (the “Pillar 1 requirements”). In addition, the PRA requires us to hold extra capital to cover risks not covered or insufficiently covered by the Pillar 1 requirements (the “Pillar 2A requirements”). At December 31, 2023, our Pillar 2A requirement (set by the PRA) was US$22.2 billion, equivalent to 2.6% of risk weighted assets, of which 1.46% must be met by common equity Tier 1.

S-29

In addition to the minimum requirements described above, UK credit institutions are required to meet several capital buffers, on a consolidated basis, with common equity Tier 1 capital. The combination of the following buffers constitutes the “combined buffer”: (i) the capital conservation buffer (“CCB”) (which is 2.5% of risk weighted assets); (ii) the global systemically important institutions (“G-SII”) buffer (which, as of January 1, 2024, is 2% of risk weighted assets, and may vary from time to time); and (iii) the countercyclical capital buffer (“CCyB”) (which is a buffer of common equity Tier 1 capital equivalent to the risk weighted assets multiplied by the weighted average of various countercyclical buffer rates that vary over time depending on the effective rates set by regulators in countries where we have relevant credit exposures – the current UK CCyB rate is 2%). As of December 31, 2023, the HSBC Group’s combined buffer was 5.2% of risk weighted assets (comprising a CCB, a G-SII and a CCyB buffer of 2.5%, 2.0% and 0.7%, respectively).

In addition to the Pillar 1 and Pillar 2A requirements and the combined buffer, there are other tools that the PRA and other relevant authorities in the UK have available to them to require UK firms to hold additional capital to address micro-prudential or macro-prudential risks as assessed by the relevant authorities in the UK. For example, the PRA introduced a firm-specific Pillar 2B buffer (the “PRA buffer”), which is an amount of capital firms should maintain in addition to the total capital requirements (Pillar 1 and Pillar 2A) and the combined buffer. The PRA buffer absorbs losses which could arise under a severe stress scenario, and is set at a level that the PRA believes will ensure that the firm can continue to meet minimum Pillar 1 and Pillar 2A requirements as well as to address any significant weaknesses in its risk management and governance. The PRA assesses the PRA buffer applicable to an institution annually (or more often if a firm’s circumstances change). Where the PRA considers there is an overlap between the combined buffer (excluding systematic buffers like the G-SII buffer) and the PRA buffer, the PRA buffer will be set as the excess capital required over and above the combined buffer. To the extent the PRA buffer is applicable, it must be met with 100% common equity Tier 1 capital, which will be in addition to the common equity Tier 1 capital used to meet the Pillar 1 and Pillar 2A capital and combined buffer requirements.

In addition, “sectoral capital requirements” could be imposed as a macro-prudential tool available to the Bank of England’s Financial Policy Committee as a means to temporarily increase firms’ capital requirements as a result of exposure to specific sectors. Under the Financial Holding Companies (Approval etc.) and Capital Requirements (Capital Buffers and Macro-prudential Measures) (Amendment) (EU Exit) Regulations 2020 (the “UK CRD V Regulations”), the PRA has the power to set sectoral capital requirements via a systemic risk buffer (“SRB”). In its policy statement PS26/20 (“PS26/20”) published on December 9, 2020, the PRA confirmed that it would not introduce such an SRB at this time. However, the PRA may consult on introducing one in future should that be necessary and appropriate. If an SRB were to be imposed in the future, it would likely form part of the combined buffer.

The PRA has also introduced requirements in relation to minimum leverage ratios pursuant to which we are required to meet (i) a minimum leverage ratio requirement set at 3.25% (calculated, in accordance with the PRA Rulebook, by dividing a firm’s Tier 1 capital by its total exposure measure) (the “PRA Leverage Ratio”), (ii) an additional leverage ratio buffer that is calibrated at 35% of the G-SII buffer (“ALRB”) and (iii) a countercyclical leverage ratio buffer that is calibrated at 35% of the CCyB (“CCyLB”). At least 75% of the Tier 1 capital required to meet the PRA Leverage Ratio must consist of common equity Tier 1 capital (with the remaining to be met with additional Tier 1 capital), while the ALRB and CCyLB must be met entirely with common equity Tier 1 capital (and the common equity Tier 1 capital used for the purposes of the PRA Leverage Ratio must not be included for the purposes of the ALRB and CCyLB).

Under Chapter 4 (or, if applicable, Rule 6.2(2) of section 6 of the PRA’s Capital Buffers and Pillar 2A Model Requirements Voluntary Requirement (“VREQ”) or any succeeding provision(s) amending or replacing such section), if a relevant firm fails to meet the combined buffer it will be subject to mandatory restrictions on certain distributions or payments, calculated by reference to a maximum distributable amount (which are defined broadly by the PRA Rulebook (or the VREQ, as applicable) as payments or distributions relating to common equity Tier 1, variable remuneration, or discretionary pension benefits and payments on additional Tier 1

S-30

instruments (such as the Securities)). These requirements apply to firms on a consolidated basis. The restrictions for failing to meet the combined buffer is scaled according to the extent of the use of the combined buffer and currently calculated as a percentage of the profits from the past four calendar quarters, net of distributions or discretionary payment. 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 payments will be permitted to be paid. As a consequence, in the event that the consolidated common equity Tier 1 is insufficient to meet the combined buffer, it may be necessary to reduce discretionary payments in whole or in part, including potentially cancelling (in whole or in part) interest payments in respect of the Securities.

The PRA also has the power under sections 192C and 192T of the FSMA to impose requirements on us, the effect of which may be to restrict or prohibit payments of interest to you, which is most likely to materialize if at any time we are failing, or are expected to fail, to meet our capital requirements. If the PRA exercises its discretion, we will cancel (in whole or in part, as required by the PRA) interest payments in respect of the Securities. In addition, as a result of measures introduced by the UK CRD V Regulations, we are subject to direct supervision by the PRA, as an approved holding company, to ensure compliance with consolidated or sub-consolidated prudential requirements and the PRA has additional powers to enforce our compliance.

The failure to meet the PRA buffer or leverage ratios or buffers will not automatically trigger restrictions on distributions; notwithstanding this, the PRA may impose requirements which could have the effect of imposing such restrictions under its supervisory powers envisaged in the Capital Instruments Regulations and FSMA. In addition, failure to meet the PRA buffer or leverage ratios or buffers could result in the preparation of a capital restoration plan. Such capital restoration plan may (but will not automatically) impose restrictions on discretionary payments, which may result in the cancellation (in whole or in part) of interest payments in respect of the Securities.

Changes to the capital and leverage frameworks may increase our capital requirements and may increase the risk that we will be subject to restrictions on distributions, resulting in our being required to cancel (in whole or in part) interest payments in respect of the Securities. Following the UK’s withdrawal from the EU, the UK regime continues to develop, with the PRA taking an increasingly significant role in developing the relevant rules. As a result of powers granted by the Financial Services Act 2021, the PRA has revoked elements of UK CRR (as defined under “Description of the Securities—Definitions”), as it stood as at IP Completion Day, and replaced them with PRA-made rules. In July 2020, the Basel Committee on Banking Supervision completed the reforms to the Basel III standards (“Basel 3.1”). In the UK, a two-stage approach to implementation has been adopted for these changes. Amendments to UK CRR along with corresponding new PRA rules, which took effect from January 1, 2022, represented the first tranche of changes to implement Basel 3.1. This included the standardized approach for measuring counterparty risk, the equity investments in funds rules, amendments to the large exposures rules, and the implementation of the net stable funding ratio. The PRA’s approach to the making of such rules was set out in its Policy Statements PS17/21 (published July 9, 2021) and PS22/21 (published October 14, 2021). The remaining elements of Basel 3.1 will be implemented as a second tranche of changes. This includes changes to the market risk rules under the Fundamental Review of the Trading Book, changes to the rules on credit risk, operational risk and credit valuation adjustment, and the implementation of the output floor. On December 12, 2023, the PRA published Policy Statement PS17/23, the first of two near-final policy statements, regarding the implementation of such Basel 3.1 changes. PS17/23 follows the PRA’s Consultation Paper CP16/22 which set out its proposed rules for the implementation of the outstanding changes, with a proposed implementation date of July 1, 2025, subject to certain transitional provisions, with a 4.5 year transitional period ending on January 1, 2030. The Basel 3.1 changes include changes to the rules on credit risk and the implementation of the output floor, which are due to be covered in a second near-final policy statement to be published in 2024.

In addition, on June 26, 2020 the EU enacted a banking response to the Covid-19 pandemic (the “CRR Quick Fix”). The CRR Quick Fix included, among other things, provisions extending the transitional phase-in arrangements in relation to IFRS 9 under CRR to the end of 2024. These provisions have been retained in UK

S-31

CRR. Further, our minimum regulatory capital requirements may increase as a result of increased provisioning under stress associated with our adoption of IFRS 9 as of January 1, 2018, the magnitude of which will depend upon several factors, including the specified stress scenario. See “—Risks Relating to the Securities—The circumstances surrounding or triggering an Automatic Conversion are unpredictable.”

Separately, certain aspects of the UK regulatory regime may restrict or prohibit us further from making interest payments on the Securities in certain circumstances. For example, under the UK Banking Act 2009, as amended (the “Banking Act”), which implemented the EU Bank Recovery and Resolution Directive (“BRRD”), the Bank of England is required to set a minimum requirement for eligible liabilities (“MREL”) for banks in the UK. The current UK MREL regime, which took effect on January 1, 2019 at a level which increased until January 1, 2022, has been designed to be broadly compatible with the term sheet published by the Financial Stability Board (the “FSB”) on total loss absorbing capacity (“TLAC”) requirements for G-SIIs. Furthermore, with effect from June 27, 2019, G-SIIs (including us) are subject to a harmonized MREL requirement, in addition to institution-specific requirements under the BRRD regime. Under PRA Supervisory Statement SS16/16 (“SS16/16”), if a UK firm does not have, or expects that it will not have, sufficient CET1, in addition to any own funds and liabilities counted towards its MREL, to meet the amount of CET1 it should maintain for the purposes of risk-weighted capital and leverage buffer requirements, it will be considered to have used, or be about to use, the buffers of the regime where the total amount of capital required to meet minimum requirements plus buffers (risk-weighted capital or leverage) is largest. The firm may have to notify the PRA as soon as practicable explaining why this has happened or is expected to happen. HSBC Holdings is aware that it can expect enhanced supervisory action and may need to prepare a capital restoration plan in such circumstances. If the PRA is not satisfied with the capital restoration plan, or with HSBC Holdings’ reasons for the shortfall, it will consider using its powers under sections 192C and 192T of the FSMA to require HSBC Holdings to take steps to strengthen its capital position (such steps could include restricting or prohibiting distributions where that is appropriate and proportionate). Likewise, if HSBC Holdings does not have sufficient CET1 to meet its minimum risk-weighted capital requirements and the combined buffer, automatic restrictions on distributions will apply under the PRA Rulebook and sections 192C and 192T of the FSMA. As a result, MREL/TLAC requirements may result in the reduction of discretionary payments (in whole or in part), including the cancellation (in whole or in part) of interest payments in respect of the Securities.

The HSBC Group’s capital requirements, including Pillar 2A requirements, by their nature, are calculated by reference to a number of factors, any one or a combination of which may not be easily observable or capable of calculation by you. Moreover, the interaction of restrictions on distributions (including interest payments on the Securities) with, and impact of, the capital requirements and buffers and leverage framework applicable to the HSBC Group, as well as the implementation of MREL/TLAC requirements, remain uncertain in many respects. Such uncertainty is expected to continue while the UK authorities develop, through the provision of guidance or otherwise, the current rules and consult on and finalize proposals for future rules to be adopted, including the implementation of Basel 3.1. See “—Risks Relating to the Securities—Other changes in law may adversely affect your rights as a securityholder.” These changes could result in more common equity Tier 1 capital and MREL/TLAC required to be held by a financial institution in order to prevent maximum distributable amount restrictions from applying. As a result of such uncertainty, you may not be able to anticipate whether we will need to reduce discretionary payments, including by cancelling interest payments (in whole or in part) in respect of the Securities, which may affect the value of your investment in the Securities.

As a holding company, our level of Distributable Items is affected by a number of factors, and insufficient Distributable Items may restrict our ability to make interest payments on the Securities.

As a holding company, our level of Distributable Items is affected by a number of factors, principally our ability to receive funds, directly or indirectly, from our operating subsidiaries in a manner that creates Distributable Items for us. Consequently, our future Distributable Items, and therefore our ability to make interest payments (see “—Risks Relating to the Securities—Interest on the Securities will be due and payable on an interest payment date only if it is not cancelled or deemed to have been cancelled, and we may cancel interest (in

S-32

whole or in part), in our absolute and sole discretion, at any time”), are a function of our existing Distributable Items, our future operating profits, our distributions and our ability to distribute or dividend profits from our operating subsidiaries up the HSBC Group structure to us. In addition, our Distributable Items may also be adversely affected by the redemption of equity instruments or the servicing of other debt or equity instruments (see “—Our holding company structure may mean that our rights to participate in assets of any of our subsidiaries upon its liquidation may be subject to prior claims of some of its creditors, including when we have loaned or otherwise advanced the proceeds received from the issuance of the Securities to such subsidiary”).

The ability of our subsidiaries to pay dividends and our ability to receive distributions from our investments in other entities is subject to applicable local laws and other restrictions, including their respective regulatory, capital and leverage requirements, statutory reserves, financial and operating performance and applicable tax laws (including, without limitation, any legislation enacted by any jurisdiction in connection with the model rules for the Pillar II solution for the OECD G20 Project on Taxation of the Digital Economy published on 20 December 2021) and any changes thereto. In particular, the continuing progress in the implementation of international principles and EU and domestic rules and regulations (including such rules and regulations in the UK or in other jurisdictions in which the HSBC Group operates) around additional loss absorbing capacity (such as TLAC and MREL) are expected to increase current capital and leverage requirements. These factors could limit the payment of dividends and distributions to us by our subsidiaries, and to the extent that we are dependent on the receipt of such dividends and distributions, as opposed to other sources of income, such as interest and other payments from our subsidiaries, this could in time restrict our ability to fund other operations or to maintain or increase our Distributable Items.

The level of our Distributable Items may be further affected by changes to regulation or the requirements and expectations of applicable regulatory authorities. In particular, capital or ring fencing requirements, both in the UK and in other jurisdictions where we have significant operations, could adversely affect our Distributable Items in the future, such as the internal MREL requirements applicable to our UK and EU banking operations, and the regulatory capital and internal TLAC requirements and buffers applicable to intermediate holding companies (“IHCs”) in the United States and potential restrictions on such IHCs’ ability to engage in capital distributions.

Further, our Distributable Items may be adversely affected by the performance of the HSBC Group’s business in general, factors affecting its financial position (including capital and leverage), the economic environment in which the HSBC Group operates and other factors outside of our control. See “—Risks Relating to HSBC’s Business.” In cases of material distress at the group level or at certain subsidiaries, regulatory authorities could write down (including to zero) or convert to common equity loans we have made to subsidiaries that qualify as internal MREL or internal TLAC, which could adversely affect our Distributable Items.

Our Distributable Items are also sensitive to the accounting impact of factors such as the redemption of preference shares and impairment charges and the carrying value of our investments in subsidiaries, which are carried at the lower of cost and their prevailing recoverable amount. Recoverable amounts depend on discounted future cash flows, which can be affected by restructurings, whether carried out for strategic reasons, to give effect to regulatory requirements (such as the implementation of the UK’s ring fencing regime) or otherwise. Any of these factors could limit our ability to maintain sufficient Distributable Items.

Our holding company structure may mean that our rights to participate in assets of any of our subsidiaries upon its liquidation may be subject to prior claims of some of its creditors, including when we have loaned or otherwise advanced the proceeds received from the issuance of the Securities to such subsidiary.

The Securities are our obligations exclusively and are not guaranteed by any person, including any of our subsidiaries. We are a non-operating holding company and, as such, our principal source of income is derived from our operating subsidiaries that hold the principal assets of the HSBC Group. As a separate legal entity, we rely on, among other things, remittance of our subsidiaries’ loan and debt securities interest payments and

S-33

dividends in order to be able to meet our obligations to you as they fall due. The ability of our subsidiaries and affiliates to pay dividends and (in certain circumstances) interest payments could be restricted by changes in regulation, statutory/contractual restrictions, exchange controls, tax laws and other requirements, which may, in turn, restrict our ability to pay any amounts due under the Securities.

In addition, because we are a holding company, our rights to participate in the assets of any subsidiary if it is liquidated will be subject to the prior claims of its creditors and any preference shareholders, except to the extent that we may be a creditor with recognized claims ranking ahead of or pari passu with such prior claims against the subsidiary.

We also have absolute discretion as to how we make our investments in, or advance funds to, our subsidiaries, including any proceeds of issuances of debt securities such as the Securities, and as to how we may restructure existing investments and funding in the future (which restructuring may be implemented without prior notification to you). The ranking of our claims in respect of such investments and funding in the event of the liquidation of a subsidiary, and their treatment in resolution, will depend in part on their form and structure and the types of claim to which they give rise. The purposes of such investments and funding, and any such restructuring, may include, among other things, the provision of different amounts or types of capital or funding to particular subsidiaries, including for the purposes of meeting regulatory requirements, such as the implementation of the MREL requirements or any equivalent requirements imposed by the Bank of England, and the FSB’s minimum TLAC requirements, in respect of such subsidiaries, which may require funding to be made on a subordinated basis, or the implementation of the Basel 3.1 requirements. See pages 155 through 156 in the 2023 Form 20-F.

In addition, the terms of some loans or investments in capital instruments issued by our subsidiaries may contain contractual mechanisms that, upon the occurrence of a trigger related to the prudential or financial condition of such subsidiary, would result in a write-down of the claim or a change in the ranking and type of claim that we have against such subsidiary. The regulatory framework applicable to our subsidiaries may also provide statutory powers to regulatory authorities to write-down or convert such loans or investments to equity depending on the prudential or financial condition of the subsidiary. In addition, such loans to and investments in our subsidiaries may also be subject to the exercise of the UK bail-in power. See “—Risks Relating to the Securities—The Securities are the subject of the UK bail-in power, which may result in your Securities being written down to zero or converted into other securities, including unlisted equity securities.” Any changes in the legal or regulatory form or ranking of a loan or investment could also affect its treatment in resolution.

If any of our subsidiaries were wound up, liquidated or dissolved, (i) you 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 such subsidiary’s creditors and/or preference shareholders (including holders of such subsidiary’s senior debt and Tier 2 and additional Tier 1 capital instruments) before we would be entitled to receive any distributions. Similarly, if any of our subsidiaries were subject to resolution proceedings (i) you may have no direct recourse against such subsidiary and (ii) you and we may also be exposed to losses pursuant to the exercise by the relevant resolution authority of resolution powers (including any applicable bail-in power).

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

We and certain of our subsidiaries are subject to supervisory stress testing exercises in a number of jurisdictions. See pages 161, 162, 175 and 240 in the 2023 Form 20-F. Failure to meet requirements of regulatory stress tests, or the failure by regulators to approve our stress test results and capital plans, could result in our or certain of our subsidiaries being required to enhance our or their capital position (including, for example, by increasing the PRA buffer). 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 our discretion to cancel (in whole or in part) interest payments in respect of the Securities).

S-34

The Securities may trade with accrued interest even though interest may not be paid on the relevant interest payment date.

The Securities may trade, and/or the prices for the Securities may appear, on the GEM and in other trading systems with accrued interest. However, if a payment of interest on any interest payment date is cancelled or deemed to have been cancelled (in each case, in whole or in part) and thus is not due and payable (see “—Risks Relating to the Securities—Interest on the Securities will be due and payable on an interest payment date only if it is not cancelled or deemed to have been cancelled, and we may cancel interest (in whole or in part), in our absolute and sole discretion, at any time”), you will not be entitled to that interest payment (in whole or in part, as applicable) on the relevant interest payment date. This may affect your ability to sell your Securities in the secondary market and, as a result, the value of your investment in the Securities.

The interest rate on the Securities will reset on each Reset Date.

The interest rate on the 2030 Securities will initially be the 2030 Securities Initial Interest Rate, from (and including) the Issue Date to (but excluding) March 11, 2030, the initial 2030 Securities Reset Date. The interest rate on the 2034 Securities will initially be the 2034 Securities Initial Interest Rate, from (and including) the Issue Date to (but excluding) September 11, 2034, the initial 2034 Securities Reset Date. However, in each case, the interest rate will be reset every five years on each Reset Date, such that the applicable per annum interest rate will be equal to the sum of the applicable Margin and the applicable Reference Rate on the relevant Reset Determination Date. As a result, the interest rate following any 2030 Securities Reset Date or 2034 Securities Reset Date may be less than the applicable Initial Interest Rate and/or the interest rate that applies immediately prior to such 2030 Securities Reset Date or 2034 Securities Reset Date, as the case may be, which would affect the amount of any interest payments under the 2030 Securities or the 2034 Securities, and, by extension, could affect their market value.

We may redeem the Securities for certain tax or regulatory reasons or during any Optional Redemption Period.

We may redeem the Securities in whole (but not in part) upon the occurrence of a Tax Event or a Capital Disqualification Event, as more particularly described under “Description of the Securities—Redemption— Special Event Redemption.” Certain of such events may occur at any time after the Issue Date and it is therefore possible that we would be able to redeem the Securities at any time after the Issue Date. A Tax Event will include, among other things, a change in law (or in its application or official interpretation) after the Issue Date whereby the deductibility for UK tax purposes of interest expense on the Securities is restricted or the Securities would no longer be treated as loan relationships for UK tax purposes or the Securities (or any part thereof) would become treated as a derivative or an embedded derivative for UK tax purposes.

Moreover, we may redeem the Securities in whole (but not in part) during any Optional Redemption Period, as more particularly described under “Description of the Securities—Redemption—Optional Redemption.”

Our Optional Redemption on any Optional Redemption Date may limit the market value of the Securities to the redemption price during the period shortly before any Optional Redemption Date. Moreover, if we redeem the Securities in any of the circumstances mentioned above, you may not be able to reinvest the redemption proceeds in securities offering a comparable yield.

In addition, any early redemption of any of the Securities may be subject to conditions imposed by the Relevant Regulator, regardless of whether such redemption would be favorable to you (see “Description of the Securities—Redemption—Redemption Conditions”). In particular, Article 78(1) of UK CRR provides that the Relevant Regulator will grant permission to reduce, call, redeem, repay or repurchase the Securities if either: (i) before or simultaneously with such reduction, call, redemption, repayment or repurchase of the Securities we replace the Securities being reduced, called, redeemed, repaid or repurchased with our own funds instruments of

S-35

equal or higher quality at terms that are sustainable for our income capacity; or (ii) we have demonstrated to the satisfaction of the Relevant Regulator that our own funds and eligible liabilities would, following such actions, exceed the requirements set out in UK CRR, Directive 2013/36/EU UK law (as defined in Article 4A of UK CRR) and in the UK legislation that implemented the BRRD, in each case, by a margin that the Relevant Regulator may consider necessary.

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 due to the deterioration in the realizable value of any Conversion Shares.

A “Capital Adequacy Trigger Event” will occur if at any time the non-transitional CET1 Ratio is less than 7.0%, as determined by us, the Relevant Regulator or any agent of the Relevant Regulator appointed for such purpose by the Relevant Regulator. See “—Risks Relating to the Securities—The circumstances surrounding or triggering an Automatic Conversion are unpredictable.”

Upon the occurrence of a Capital Adequacy Trigger Event, an Automatic Conversion will occur on the Conversion Date. Following an Automatic Conversion, you will receive only (i) the Conversion Shares (based on the Conversion Price) or (ii) if we elect, in our sole and absolute discretion, that a Conversion Shares Offer be made, the Conversion Shares Offer Consideration, which will comprise Conversion Shares (based on the Conversion Price) and/or cash (based on the Conversion Shares Offer Price) depending on the results of the Conversion Shares Offer. See “Description of the Securities—Automatic Conversion Upon Capital Adequacy Trigger Event” and “—Risks Relating to the Securities—You 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.” The Automatic Conversion will be irrevocable and, following the occurrence of an Automatic Conversion, you will not be entitled to any compensation in the event of any improvement in the non-transitional CET1 Ratio after the Conversion Date.

“Conversion Shares” are our ordinary shares to be issued to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) following an Automatic Conversion. Because a Capital Adequacy Trigger Event will only occur at a time when the non-transitional CET1 Ratio has deteriorated significantly, a Capital Adequacy Trigger Event may be accompanied by a deterioration in the market price of our ordinary shares, which may be expected to continue after the occurrence of a Capital Adequacy Trigger Event. In addition, there may be a delay in your receiving your Conversion Shares following a Capital Adequacy Trigger Event (in particular if we elect that a Conversion Shares Offer be conducted), during which time the market price of our ordinary shares may further decline. Therefore, the realizable value of any Conversion Shares received may be significantly less than (x) the pounds sterling (or any other currency in which our ordinary shares may trade) equivalent of the Conversion Price and/or (y) the Conversion Shares Offer Price, and you will no longer have a debt claim in relation to the Securities. As a result, you may lose all or part of the value of your investment in the Securities following an Automatic Conversion. See “—Risks Relating to the Securities—Upon the occurrence of a Capital Adequacy Trigger Event, your rights will be subordinated further.” See also “—Risks Relating to the Securities—You will bear the risk of depreciation of pounds sterling against the U.S. dollar.”

You will have limited rights after a Capital Adequacy Trigger Event and the issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with terms of the Securities) will constitute an irrevocable and automatic release of all of our obligations in respect of the Securities.

Following an Automatic Conversion, we will be obligated to issue the Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities), which will hold the Conversion Shares on your behalf. If we do not deliver the Conversion Shares

S-36

to the Conversion Shares Depository following a Capital Adequacy Trigger Event, the only claims you will have against us will be for specific performance to have such Conversion Shares issued and delivered. Moreover, you will not have any rights against us with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on, or in respect of, the Securities, in each case that is not due and payable, which liabilities will be automatically released. Accordingly, the principal amount of the Securities will equal zero at all times thereafter and any interest will be cancelled or deemed to have been cancelled at all times thereafter and will not be due and payable, including 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.

Once the Conversion Shares are delivered to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities), all of our obligations under the Securities will be irrevocably and automatically released in consideration of such issuance to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities), and under no circumstances will such released obligations be reinstated. With effect from the Conversion Date, you will have recourse only to the Conversion Shares Depository for the delivery to you of Conversion Shares or, if we elect that a Conversion Shares Offer be made, of any Conversion Shares Offer Consideration to which you are entitled.

In addition, we have not yet appointed a Conversion Shares Depository and we may not be able to appoint a Conversion Shares Depository if an Automatic Conversion occurs. In such case, we will effect, by means we deem reasonable under the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to you directly), the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to you. Such arrangements may be disadvantageous to, and more restrictive on, you, such as involving a longer period of time before you receive your Conversion Shares or Conversion Shares Offer Consideration, as applicable, than would be the case under the arrangements expected to be entered into with a Conversion Shares Depository. Nevertheless, such issuance also will irrevocably and automatically release all of our obligations under the Securities as if the Conversion Shares had been issued to the Conversion Shares Depository.

You will bear the risk of changes in the non-transitional CET1 Ratio.

The value of your Securities is expected to be affected by changes in the non-transitional CET1 Ratio. Any indication that the non-transitional CET1 Ratio is moving towards the level of a Capital Adequacy Trigger Event may have an adverse effect on the value of your Securities. Moreover, we currently only publicly report the non-transitional CET1 Ratio quarterly as of the period end, and therefore, there may be no prior warning of adverse changes in our non-transitional CET1 Ratio. Any unexpected change in the non-transitional CET1 Ratio that we report or anticipate in our quarterly reports or otherwise, or that is anticipated by the market, may lead to an immediate and significant decrease in the value of your Securities. See “—Risks Relating to the Securities—The circumstances surrounding or triggering an Automatic Conversion are unpredictable” for a description of factors that may increase the risk of occurrence of a Capital Adequacy Trigger Event, including the implementation of the Basel standards in the UK after the date hereof.

The circumstances surrounding or triggering an Automatic Conversion are unpredictable.

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 our control.

A Capital Adequacy Trigger Event could occur on any date on which the non-transitional CET1 Ratio is below 7.0%, as determined by us, the Relevant Regulator or any agent of the Relevant Regulator appointed for such purpose by the Relevant Regulator. Although we currently publicly report the non-transitional CET1 Ratio only as of the last day of each of our financial quarters, the PRA, as part of its supervisory activity, may instruct

S-37

us to calculate such ratio as of any date, including if we are subject to recovery and resolution actions by the relevant UK resolution authority. Moreover, we might otherwise determine to calculate such ratio in our own discretion. Accordingly, a Capital Adequacy Trigger Event could occur on any date. Moreover, we will calculate CET1 Capital and Risk Weighted Assets on a “fully loaded basis” without applying the transitional provisions set out in Part Ten of UK CRR (which currently means the phase-in arrangements for the regulatory capital impact of IFRS 9) (the “Transitional Provisions”). As a result, the CET1 Ratio may be lower than it would be were we to calculate the CET1 Ratio applying the IFRS 9 phase-in arrangements. A Capital Adequacy Trigger Event may therefore be triggered (because the non-transitional CET1 Ratio is less than 7.0%), which could cause you to lose all or part of the value of your investment in the Securities, even when our common equity Tier 1 ratio as calculated by applying the Transitional Provisions is above 7.0%.

Separately, changes in the non-transitional CET1 Ratio may be caused by changes in the amount of CET1 Capital and/or Risk Weighted Assets (each of which will be calculated by us and will be binding on the trustee, the paying agent and you). Accordingly, the non-transitional CET1 Ratio could be affected by one or more factors, including changes to our business and our future earnings, dividend payments, regulatory changes (including changes to definitions, interpretations and calculations of regulatory capital ratios and their components, including CET1 Capital and Risk Weighted Assets, as described further below), revisions to models used by us to calculate our capital requirements (or revocation of, or amendments to, the regulatory permissions for using such models), actions that we are required to take at the discretion of the Relevant Regulator, accounting rule changes (as described further below), tax law changes, the HSBC Group’s ability to manage Risk Weighted Assets in both its ongoing businesses and those it may seek to exit and foreign currency movements (due to changes in foreign exchange rates resulting in changes to the U.S. dollar equivalent value of foreign currency denominated capital resources and Risk Weighted Assets).

The actual impact of the Capital Instruments Regulations on UK capital ratios is also subject to ongoing changes, including changes to UK CRR to implement the revised Basel III standards, or changes to the way in which the PRA interprets and applies these requirements to UK banks (including with respect to individual model approvals granted by the PRA), as described further below. See “—Risks Relating to the Securities—Other changes in law may adversely affect your rights as a securityholder.”

The PRA has published several supervisory statements and policy statements setting out the PRA’s expectations in relation to capital and leverage ratios and the quality of capital, respectively, including SS 45/15 (as amended) and PS 27/15 (each released on December 7, 2015), PS 21/17 (released in October 2017), PS 28/18 (released in November 2018), PS 21/21 (released in October 2021), PS 5/23 (released in May 2023) and, most recently, SS45/15 (released in July 2024) which took effect on August 5, 2024. Nonetheless, if the PRA rules, guidance or expectations in relation to capital or leverage were to be amended in the future in a manner other than as set out in the statements, it could be materially more difficult for the HSBC Group to maintain compliance with prudential requirements.

Applicable accounting rules, or changes to regulatory adjustments that modify the regulatory impact of accounting rules, may affect the calculation of the non-transitional CET1 Ratio. For example, as of January 1, 2018, we have adopted IFRS 9, where the recognition and measurement of impairments is intended to be more forward-looking, and the resulting impairment charge may be more volatile. Over time, future impairment charges may cause significant decreases in our non-transitional CET1 Ratio, especially given that the transitional arrangements under UK CRR (which soften the impact that IFRS 9 has on our loan loss allowances) were phased out by the end of 2022 (or, in accordance with the CRR Quick Fix, are being phased out in 2024, in respect of relevant allowances raised from January 1, 2020). In addition, we continue to test and refine our models for purposes of determining expected credit losses, and any revisions to our models may result in significant changes to our regulatory capital position. Even if changes in applicable accounting rules, or changes to regulatory adjustments that modify the regulatory impact of accounting rules, are not yet in force as of the relevant calculation date, the Relevant Regulator could require us to reflect such changes in any particular calculation of the non-transitional CET1 Ratio. Moreover, the HSBC Group’s non-transitional CET1 Ratio is a non-IFRS measure, and our interpretation of the Capital Instruments Regulations and the basis of our calculation of this

S-38

financial measure may be different from those of other financial institutions. The estimates are also based on a number of assumptions. For further information, see the section entitled “Capital Overview” in the 2023 Form 20-F.

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, including prices, volatility and liquidity, may be affected by any threat of a Capital Adequacy Trigger Event and, as a result, the Securities are not necessarily expected to follow the trading behavior associated with other types of securities, including our debt securities. As a result, you may not be able to sell your Securities easily, or at all, or at prices that will provide them with a yield comparable to other types of subordinated securities. In addition, the risk of an Automatic Conversion could lead to a decline in the price of our ordinary shares, which could have a material adverse effect on the market value of the Conversion Shares you receive.

The non-transitional CET1 Ratio, and more generally, our overall capital position, will be affected by our business decisions and our and your interests may not be aligned.

As discussed in “—Risks Relating to the Securities—The circumstances surrounding or triggering an Automatic Conversion are unpredictable” and “—Risks Relating to the Securities—Existing or new capital or leverage requirements may result in restrictions on making interest payments in respect of the Securities, in which case interest payments will be cancelled, which you may not be able to anticipate,” the non-transitional CET1 Ratio, and more generally, our overall capital position, could be affected by a number of factors, including the HSBC Group’s decisions relating to its businesses and operations, as well as the management of its capital position. The HSBC Group will have no obligation to consider your interests in connection with such decisions, including in respect of its capital management. Such decisions could cause you to lose all or part of the value of your investment in the Securities due to their effect on the non-transitional CET1 Ratio, and you will not have any claim against us or any other member of the HSBC Group relating to such decisions, regardless of whether they result in the occurrence of a Capital Adequacy Trigger Event and/or mandatory distribution restrictions that result in the cancellation of interest payments (in whole or in part) in respect of the Securities.

Upon the occurrence of a Capital Adequacy Trigger Event, your rights will be subordinated further.

Upon the occurrence of a Capital Adequacy Trigger Event, you will rank as a holder of our ordinary shares (or beneficial owner of our ordinary shares as evidenced by the Securities). Accordingly, you will be subordinated further on a winding-up or administration due to the change in your status from being the holder of an instrument ranking pari passu with holders of our most senior class of preference shares (and therefore ahead of holders of our ordinary shares). Even if other creditors with claims that rank pari passu with the Securities, or junior to the Securities but senior to our ordinary shares, are paid in full, following a Capital Adequacy Trigger Event, you will have no rights to the repayment of the principal amount of the Securities or the payment of interest on the Securities that is not due or payable. As a result, upon the occurrence of a Capital Adequacy Trigger Event, you may lose all or part of your investment in the Securities irrespective of whether we have sufficient assets available to settle in winding-up proceedings or otherwise what would have been your claims as a securityholder, the claims of other creditors subordinated to the same extent as the Securities and the claims of other creditors subordinated to a greater extent than the Securities but senior to our ordinary shares.

You 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.

We may elect, in our sole and absolute discretion, that the Conversion Shares Depository conduct a Conversion Shares Offer. If all of the Conversion Shares are sold in the Conversion Shares Offer, you will be entitled to receive, in respect of each Security, the pro rata share of the cash proceeds from the sale of the

S-39

Conversion Shares attributable to such Security converted from pounds sterling into U.S. dollars at the Prevailing Rate as of the date that is three Depository Business Days prior to the relevant Settlement Date as determined by the Conversion Shares Depository (less the pro rata share of any foreign exchange transaction costs) (the “pro rata cash component”). If some but not all of the Conversion Shares are sold in the Conversion Shares Offer, you will be entitled to receive, in respect of each Security, (a) the pro rata cash component and (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 (the “pro rata Conversion Shares component”). If no Conversion Shares are sold in a Conversion Shares Offer, you will be entitled to receive, in respect of each Security, the relevant Conversion Shares attributable to such Security rounded down to the nearest whole number of Conversion Shares.

Any pro rata cash component will be subject to deduction from any such cash proceeds 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 any interest in the Conversion Shares to the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) in order for the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) to conduct the Conversion Shares Offer. Moreover, no interest or other compensation is payable in respect of the period elapsed from the Conversion Date to the date of delivery of any pro rata cash component or Conversion Shares.

Furthermore, neither the occurrence of a Capital Adequacy Trigger Event nor, following the occurrence of a Capital Adequacy Trigger Event, the election (if any) by us to undertake a Conversion Shares Offer, will preclude us from undertaking a rights issue or other equity issuance at any time on such terms as we deem appropriate, at our sole discretion, including—for the avoidance of doubt—the offer of our ordinary shares at or below the Conversion Shares Offer Price. Additionally, there can be no assurance that the Conversion Shares Offer would be conducted on an SEC-registered basis.

In addition, we 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 (which may be as many as 40 business days following the delivery of the Conversion Shares Offer Notice). Accordingly, you would not know the composition of the Conversion Shares Offer Consideration to which you 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 your right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities), and your rights will be limited accordingly.

Following an Automatic Conversion (and thus the issuance of the Conversion Shares to the Conversion Shares Depository on the Conversion Date), the Securities will remain in existence until the applicable Cancellation Date (at which point the Securities will be cancelled) for the sole purpose of evidencing your right to receive Conversion Shares or the Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities). If we have been unable to appoint a Conversion Shares Depository, we will effect, by means we deem reasonable under the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to the securityholders directly), the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to you. See also “—Risks Relating to the Securities—You will have limited rights after a Capital Adequacy Trigger Event and Issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with terms of the Securities) will constitute an irrevocable and automatic release of all of our obligations in respect of the Securities.” Moreover, the Securities may cease to be admitted to Euronext Dublin’s Official List and to be traded on the GEM (the exchange-regulated market of Euronext Dublin) after the Suspension Date.

S-40

Although we currently expect that beneficial interests in the Securities will be transferrable between the Conversion Date and the Suspension Date, there is no guarantee that this will be the case. Even if the Securities are transferable following the Automatic Conversion, there is no guarantee that an active trading market will exist for the Securities, and the Securities may cease to be admitted to Euronext Dublin’s Official List and to be traded on the GEM before the Suspension Date. Accordingly, the price received for the sale of any beneficial interest in 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 DTC at an earlier time than currently expected, it may not be possible to transfer beneficial interests in the Securities in DTC and trading in the Securities may cease.

In addition, we have been advised by DTC that it will suspend all clearance and settlement of transactions in the Securities on the Suspension Date. As a result, you will not be able to settle the transfer of any Securities through DTC following the Suspension Date, and any sale or other transfer of the Securities that you may have initiated prior to the Suspension Date that is scheduled to match or settle after the Suspension Date will be rejected by DTC and will not be matched or settled through DTC.

Moreover, although you will become a beneficial owner of your pro rata share of 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), you will not be able to sell or otherwise transfer any Conversion Shares until such time as they are delivered to you and registered in your name.

You must submit an Automatic Conversion Settlement Notice and may need an account with a clearing system in order to receive delivery of the Conversion Shares or any Conversion Shares Offer Consideration, as applicable, and you will be required to provide further documentation if such Automatic Conversion Settlement Notice is delivered after the Notice Cut-off Date.

In order to obtain delivery of the relevant Conversion Shares or any Conversion Shares Offer Consideration, as applicable, you (or your nominee, custodian or other representative) must deliver an Automatic Conversion Settlement Notice (and the relevant Securities, if held in definitive form) to the Conversion Shares Depository.

The Automatic Conversion Settlement Notice must contain certain information, including your CREST or other clearing system account details (assuming the Conversion Shares are a participating security in a clearing system). Accordingly, in such cases, you (or your nominee, custodian or other representative) must have an account with the relevant clearing system in order to receive the Conversion Shares or pro rata Conversion Shares component, as applicable. Moreover, the Conversion Shares Depository will determine, in its sole and absolute discretion, whether your Automatic Conversion Settlement Notice has been properly completed and delivered, and such determination will be conclusive and binding on you. If you fail to properly complete and deliver an Automatic Conversion Settlement Notice (and the relevant Securities, if held in definitive form) the Conversion Shares Depository will be entitled to treat such Automatic Conversion Settlement Notice as null and void.

Although the Conversion Shares Depository will continue to hold the relevant Conversion Shares or Conversion Shares Offer Consideration, as applicable, if you fail to properly complete and deliver an Automatic Conversion Settlement Notice on or before the Notice Cut-off Date, the relevant Securities will be cancelled on the Final Cancellation Date (which will be a date at most 15 business days after the Notice Cut-off Date). Moreover, after the Notice Cut-off Date you will continue to be required to provide an Automatic Conversion Settlement Notice, as well as evidence of your entitlement to the relevant Conversion Shares or the Conversion Shares Offer Consideration, as applicable. Such evidence must be satisfactory to the Conversion Shares Depository in its sole and absolute discretion in order for you to receive delivery of such Conversion Shares or Conversion Shares Offer Consideration, as applicable.

S-41

We will have no liability to you for any loss resulting from your failure to receive any Conversion Shares or Conversion Shares Offer Consideration, as applicable, or from any delay in the receipt thereof, in each case as a result of your (or your custodian, nominee, broker or other representative) failing to duly submit an Automatic Conversion Settlement Notice (and the relevant Securities, if held in definitive form) on a timely basis or at all.

You will have limited remedies.

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

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. Payment of the principal amount of the Securities will 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 will result if (x) 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 calendar days of the making of such order, (y) our ordinary shareholders adopt an effective resolution for our winding-up (other than, in the case of either (x) or (y) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (z) following the appointment of an administrator, the administrator gives notice that it intends to declare and distribute a dividend.

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 the Securities—Default and Remedies—No Other Remedies,” for the trustee, in accordance with the Indenture, 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.

Although the trustee may without further notice institute such proceedings against us as it may deem fit to enforce any term, obligation or condition binding upon us under the Securities or the Indenture (other than any of our payment obligations under, or arising from, the Securities or the Indenture, including payment of any principal or interest, including Additional Amounts) (such obligation, a “Performance Obligation”), the sole and exclusive remedy that the trustee (acting on your behalf) and/or you may seek under the Securities and the Indenture is specific performance under the laws of the State of New York. Moreover, to the extent any judgment or other award given in such proceedings requires the payment of money by us, whether by way of damages or otherwise (a “Monetary Judgment”), the trustee (acting on your behalf) and/or you may not enforce, and will not be entitled to enforce, or otherwise claim such Monetary Judgment against us, except by proving such Monetary Judgment in our winding-up or administration. As such, we will not be obliged to pay any sum or sums, in cash or otherwise (including damages), as a consequence of the institution of any such proceedings for a breach of any Performance Obligation, except where you prove any Monetary Judgment in our winding-up or administration.

Furthermore, by your acquisition of the Securities, you will acknowledge and agree that (i) the sole and exclusive remedy that you and/or the trustee (acting on your behalf) may seek under the Securities and the Indenture for a breach by us of a Performance Obligation is specific performance under the laws of the State of New York, (ii) you will not (and waive any right to) seek, and will not (and waive any right to) direct the trustee (acting on your behalf) to seek, any other remedy against us in respect of any breach by us of a Performance Obligation, (iii) you will not (and waive any right to) enforce, and will not be entitled to enforce (and waive any such entitlement), or otherwise claim (and waive any other right to claim) a Monetary Judgment against us, except by proving such Monetary Judgment in our winding-up or administration and (iv) to the extent permitted by the Trust Indenture Act, you will waive any and all claims, in law and/or in equity, against the trustee for, and

S-42

agree not to initiate a suit, against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in connection with your right to enforce a Performance Obligation in accordance with the terms of the Indenture.

You will bear the risk of depreciation of pounds sterling against the U.S. dollar.

The Conversion Price is fixed at $3.550 per Conversion Share, subject to certain anti-dilution adjustments (see “Description of the Securities—Anti-dilution—Adjustment of Conversion Price and Conversion Shares Offer Price”). Our ordinary shares trade primarily in pounds sterling, as well as in Hong Kong dollars. The U.S. dollar value of our ordinary shares may fluctuate depending on the exchange rate between the U.S. dollar and pounds sterling (or any other currency in which our ordinary shares may trade). For example, if pounds sterling (or any other currency in which our ordinary shares may trade) depreciates relative to the U.S. dollar, the U.S. dollar value of our ordinary shares will decrease. Because the Conversion Price is denominated in U.S. dollars, depreciation of pounds sterling (or any other currency in which our ordinary shares may trade) against the U.S. dollar may result in the U.S. dollar value of any Conversion Shares you receive following an Automatic Conversion being significantly less than the price implied by the Conversion Price.

If a Conversion Shares Offer is made, the Conversion Shares Offer Price will be in pounds sterling and the cash consideration received for any Conversion Shares sold in such Conversion Shares Offer initially will be denominated in pounds sterling. Such pounds sterling cash consideration will be converted into U.S. dollars at the Prevailing Rate as of the date on which the cash proceeds are delivered to you (less the pro rata share of any foreign exchange transaction costs). Accordingly, a decline in the value of pounds sterling relative to the U.S. dollar between the Issue Date and the date on which the cash proceeds are converted into U.S. dollars will result in your receiving an amount of cash proceeds in U.S. dollars that is less than if the Conversion Shares had been sold at the Conversion Price.

In addition, following a Capital Adequacy Trigger Event there may be a delay in your receiving your Conversion Shares (in particular if we elect that a Conversion Shares Offer be conducted) and/or a delay in converting the pounds sterling cash consideration into U.S. dollars after the Conversion Shares Offer, during which time the exchange rate of pounds sterling against the U.S. dollar may further decline.

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

As a result, the realizable value in U.S. dollars of the Conversion Shares upon a Capital Adequacy Trigger Event could be substantially lower than that implied by the U.S. dollar price paid for the Securities at the time of their purchase.

You do not have anti-dilution protection in all circumstances.

The number of Conversion Shares to be issued to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date will equal the quotient obtained by dividing the (i) aggregate principal amount of the Securities then outstanding immediately prior to the Automatic Conversion on the Conversion Date by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The Conversion Price is fixed at the time of issue of the Securities at $3.550 per Conversion Share. Although the Conversion Price will be adjusted in certain instances in an effort to preserve your economic interest in us, including if there is a consolidation, reclassification or subdivision of our ordinary shares which alters the number of our ordinary shares in issue, an issuance of ordinary shares in certain circumstances by way of capitalization of profits or reserves, certain issues of rights for our ordinary shares, an Extraordinary Dividend or a Qualifying Takeover Event, adjustments are not required for every corporate or other event that may affect the market price of the Conversion Shares and an Independent Financial Adviser may make modifications as it determines to be

S-43

appropriate. See “Description of the Securities—Anti-Dilution” and “Description of the Securities—Qualifying Takeover Event.” The adjustment events that are included are less extensive than those often included in the terms of convertible securities. Moreover, 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). As a result, the Conversion Price or the New Conversion Price, as applicable, may not reflect the market price of our ordinary shares or the Approved Entity Shares, respectively, which could be significantly lower than the Conversion Price or the New Conversion Price, respectively. Accordingly, the occurrence of events in respect of which no adjustment to the Conversion Price or New Conversion Price, as applicable, is made may adversely affect the value of the Securities.

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

If a Takeover Event is a Qualifying Takeover Event (because the Acquirer is an Approved Entity and the New Conversion Condition is satisfied), then following an Automatic Conversion the Securities will become convertible or exchangeable into the Approved Entity Shares at the New Conversion Price as described under “Description of the Securities—Anti-Dilution” and “Description of the Securities—Qualifying Takeover Event.” 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.

In addition, we and the Acquirer have certain discretion in determining whether a Qualifying Takeover Event has occurred as it requires the New Conversion Condition to be satisfied. The New Conversion Condition will be satisfied only if we have entered into arrangements, to our satisfaction, with the Approved Entity pursuant to which the Approved Entity irrevocably undertakes to the trustee, for the benefit of securityholders of the affected Securities, to (i) deliver the Approved Entity Shares to the Conversion Shares Depository upon a conversion of the Securities and (ii) ensure that, for so long as the Securities are outstanding, its ordinary share capital shall continue to constitute Approved Entity Shares pursuant to, and subject to the conditions specified under, “Description of the Securities—Qualifying Takeover Event.” If we are unable to enter into such arrangements within seven business days following the occurrence of a Takeover Event, the New Conversion Condition would not be satisfied.

If our ordinary shares become delisted following a non-Qualifying Takeover Event or otherwise, the Securities will be convertible into unlisted ordinary shares upon an Automatic Conversion. Unlisted shares may be more illiquid than listed shares, and therefore, may have little or no resale value. In addition, where a non-Qualifying Takeover Event occurs because the Acquirer is a Governmental Entity (and therefore not an Approved Entity), the Securities will not be convertible into, or exchangeable for, any securities or other instruments of such Governmental Entity or any other person or entity (other than us). Accordingly, a Takeover Event that is not a Qualifying Takeover Event is likely to have an adverse effect on the value of the Securities.

Under the terms of the Securities, you will agree to be bound by the exercise of any UK bail-in power by the relevant UK resolution authority.

You will agree to be bound by the exercise of any UK bail-in power (as defined under “Description of the Securities—Definitions”) and you should consider the risk that you may lose all of your investment, including the principal amount plus any accrued interest, if the UK bail-in power is acted upon or that any remaining outstanding Securities or securities into which the Securities are converted, including our ordinary shares, may be of little value at the time of conversion and thereafter (as described under “—Risks Relating to the Securities—The Securities are the subject of the UK bail-in power, which may result in your Securities being written down to zero or converted into other securities, including unlisted equity securities”).

Specifically, by your acquisition of the Securities, you (which, for these purposes, includes each beneficial owner) will acknowledge, accept, consent and agree, notwithstanding any other term of the Securities, the

S-44

Indenture or any other agreements, arrangements or understandings between us and you, to be bound by (a) the effect of the exercise of any UK bail-in power by the relevant UK resolution authority (as defined under “Description of the Securities—Agreement with Respect to the Exercise of UK Bail-in Power”); and (b) the variation of the terms of the Securities or the Indenture, if necessary, to give effect to the exercise of any UK bail-in power by the relevant UK resolution authority. No repayment or payment of Amounts Due (as defined under “Description of the Securities—Agreement with Respect to the Exercise of UK Bail-in Power”) will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise. Moreover, you (which, for these purposes, includes each beneficial owner) will consent to the exercise of any UK bail-in power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to the Securities. For more information, see “Description of the Securities—Agreement with Respect to the Exercise of UK Bail-in Power.”

The Securities are the subject of the UK bail-in power, which may result in your Securities being written down to zero or converted into other securities, including unlisted equity securities.

On January 1, 2015, the Banking Act and other primary and secondary legislative instruments were amended to give effect to BRRD in the UK. The stated aim of BRRD is to provide supervisory authorities, including (at the time) the relevant UK resolution authority, with common tools and powers to address banking crises pre-emptively in order to safeguard financial stability and minimize taxpayers’ contributions to bank bail-outs and/or exposure to losses.

As the parent company of a UK bank, we are subject to the Banking Act, which gives wide powers in respect of UK banks and their parent and other group companies to His Majesty’s Treasury (“HM Treasury”), the Bank of England, the PRA and the Financial Conduct Authority (the “FCA”) in circumstances where a UK bank has encountered or is likely to encounter financial difficulties. As a result, the Securities are subject to existing UK bail-in powers under the Banking Act and may be subject to future UK bail-in powers under existing or future legislative and regulatory proposals. In particular, the Banking Act was amended to implement the power to write-down and convert capital instruments and (where the institution concerned is not a resolution entity) certain internal non-own funds liabilities (“relevant internal liabilities”) (the “capital instruments and liabilities write-down and conversion power”) and a “bail-in” tool, both of which may be exercised by the Bank of England (as a relevant UK resolution authority), form part of the UK bail-in power and may result in the Securities being partially or fully written down or converted to common equity Tier 1 instruments. The capital instruments and liabilities write-down and conversion power could be exercised in relation to the Securities and the use of the capital instruments and liabilities write-down and conversion power does not preclude a subsequent use of the bail-in power.

The capital instruments and liabilities write-down and conversion power may be exercised independently of, or in combination with, the exercise of a resolution tool (other than the bail-in tool), and such power allows resolution authorities to cancel all or a portion of the principal amount of capital instruments and relevant internal liabilities and/or convert such capital instruments and relevant internal liabilities into common equity Tier 1 instruments when an institution and/or, in the case of a holding company, an institution in its group, has reached the point of non-viability. The Bank of England or PRA determines the point of non-viability for such purposes as the point at which the relevant institution meets the conditions for resolution or will no longer be viable unless the relevant capital instruments are written down or extraordinary public support is provided and without such support the appropriate authority determines that the institution would no longer be viable. The Bank of England will exercise the capital instruments and liabilities write-down and conversion power in a specific order such that common equity must be written off, cancelled or appropriated from the existing shareholders in full before additional Tier 1 instruments are affected, additional Tier 1 instruments must be written off or converted in full before Tier 2 instruments are affected and (in the case of a non-resolution entity) Tier 2 instruments must be written off or converted in full before relevant internal liabilities are affected. Where the capital instruments and liabilities write-down and conversion power is used, the write-down is permanent and investors receive no

S-45

compensation (save that common equity Tier 1 instruments may be required to be issued to holders of written-down instruments). The capital instruments and liabilities write-down and conversion power is not subject to the “no creditor worse off” safeguard (unlike the bail-in power described below).

Where the conditions for resolution exist, the Bank of England may use the bail-in tool (individually or in combination with other resolution tools) to cancel all or a portion of the principal amount of, or interest on, certain unsecured liabilities of a failing financial institution and/or convert certain debt claims into another security, including ordinary shares of the surviving entity. In addition, the Bank of England may use the bail-in tool to, among other things, replace or substitute the issuer as obligor in respect of debt instruments, modify the terms of debt instruments (including altering the maturity (if any) and/or the amount of interest payable and/or imposing a temporary suspension on payments), discontinue the listing and admission to trading of financial instruments and/or transfer securities of the relevant financial institution to a third party appointed by the Bank of England. The Bank of England must apply the bail-in tool in accordance with a specified preference order. In particular, the Banking Act requires resolution authorities to write-down or convert debts in the following order: (i) additional Tier 1 instruments, (ii) Tier 2 instruments, (iii) other subordinated claims that do not qualify as additional Tier 1 or Tier 2 instruments and (iv) certain senior claims. As a result, additional Tier 1 instruments (including the Securities) may be fully or partially written down or converted before subordinated debt that does not qualify as an additional Tier 1 or Tier 2 instrument (and any such subordinated debt would only be written down or converted if the reduction of additional Tier 1 and Tier 2 instruments does not sufficiently reduce the aggregate amount of liabilities that must be written down or converted). Unlike the capital instruments and liabilities write-down and conversion power, the bail-in tool has a safeguard designed to leave no creditor worse off than in the case of insolvency. However, due to the discretion afforded to the Bank of England, the claims of some creditors whose claims would rank equally with yours may be excluded from being subject to the bail-in tool. The greater number of such excluded creditors there are, the greater the potential impact of the bail-in tool on other creditors who have not been excluded (which may include you).

Any exercise of the write-down and conversion of capital instruments and liabilities power or the bail-in power in respect of the Securities could occur before a Capital Adequacy Trigger Event occurs pursuant to the terms of the Securities and any consequent conversion of the Securities into Conversion Shares. The outcome of any such exercise of these powers may include the Securities being fully written down, in which case investors in the Securities will not have their Securities converted as contemplated by the terms of the Indenture following the occurrence of a Capital Adequacy Trigger Event.

Moreover, to the extent the UK bail-in power is exercised pursuant to the Banking Act or otherwise, any securities issued upon conversion of your Securities may not meet the listing requirements of any securities exchange, and our outstanding listed securities may be delisted from the securities exchanges on which they are listed. Any securities you receive upon conversion of your Securities (whether debt or equity) may not be listed for at least an extended period of time, if at all, or may be on the verge of being delisted by the relevant exchange, including, for example, our American depositary receipts listed on the New York Stock Exchange, or our ordinary shares listed on the London Stock Exchange or otherwise. Additionally, there may be limited, if any, disclosure with respect to the business, operations or financial statements of the issuer (which may be an entity other than HSBC Holdings) of any securities issued upon conversion of your Securities, or the disclosure with respect to any existing issuer may not be current to reflect changes in the business, operations or financial statements as a result of the exercise of the UK bail-in power.

Moreover, the exercise of the UK bail-in power and/or other actions implementing the UK bail-in power may require interests in the Securities to be held or taken, as the case may be, through clearing systems, intermediaries or persons other than DTC. Notably, in some circumstances, the relevant UK resolution authority may decide to apply a deferred bail-in, where liabilities are not written down at the start of the resolution but are transferred to a depositary to hold during the bail-in period with the terms of the write-down being determined at a later point in the bail-in period. Furthermore, the trustee may be unwilling to continue serving in its capacity as trustee for the Securities, subject to the terms of the Indenture. As a result, there may not be an active market for any Securities you may hold after the exercise of the UK bail-in power.

S-46

You should consider the risk that you may lose all of your investment, including the principal amount plus any accrued interest, if the UK bail-in power is acted upon or that any remaining outstanding Securities or securities into which your Securities are converted, including our ordinary shares, may be of little value at the time of conversion and thereafter. In addition, trading behavior, including prices and volatility, may be affected by the threat of bail-in and, as a result, your Securities are not necessarily expected to follow the trading behavior associated with other types of securities. See also “—Risks Relating to the Securities—Other powers contemplated by the Banking Act may affect your rights under, and the value of your investment in, the Securities.”

Your rights may be limited in respect of the exercise of the UK bail-in power by the relevant UK resolution authority.

There may be limited protections, if any, that will be available to holders of securities subject to the UK bail-in power (including the Securities) and to the broader resolution powers of the relevant UK resolution authority. For example, although under the Banking Act the Bank of England’s resolution instrument with respect to the exercise of the bail-in tool must set out the provisions allowing for securities to be transferred, cancelled or modified (or any combination of these), the resolution instrument may make any other provision that the Bank of England considers to be appropriate in exercising its specific powers. Such other provisions are expected to be specific and tailored to the circumstances that have led to the exercise of the bail-in tool under the Banking Act and there is uncertainty as to the extent to which usual processes or procedures under English law will be available to holders of securities (including the Securities). Accordingly, you may have limited or circumscribed rights to challenge any decision of the Bank of England or other relevant UK resolution authority to exercise its UK bail-in power.

Other powers contemplated by the Banking Act may affect your rights under, and the value of your investment in, the Securities.

In addition to the capital instruments and liabilities write-down and conversion power and the bail-in tool, the Banking Act includes powers to (a) transfer all or some of the securities issued by a UK bank or its parent, or all or some of the property, rights and liabilities of a UK bank or its parent (which would include the Securities), to a commercial purchaser or, in the case of securities, into temporary public ownership (to HM Treasury or an HM Treasury nominee), or, in the case of property, rights or liabilities, to a bridge bank (an entity owned by the Bank of England); (b) together with another resolution tool only, transfer impaired or problem assets to one or more publicly owned asset management vehicles to allow them to be managed with a view to maximizing their value through eventual sale or orderly wind-down; (c) override any default provisions, contracts or other agreements, including provisions that would otherwise allow a party to terminate a contract or accelerate the payment of an obligation; (d) commence certain insolvency procedures in relation to a UK bank; and (e) override, vary or impose contractual obligations, for reasonable consideration, between a UK bank or its parent and its group undertakings (including undertakings which have ceased to be members of the group), in order to enable any transferee or successor bank of the UK bank to operate effectively.

The Banking Act also gives power to HM Treasury to make further amendments to the law for the purpose of enabling it to use these powers effectively, potentially with retrospective effect.

The powers set out in the Banking Act could affect how credit institutions (and their parent companies) and investment firms are managed as well as, in certain circumstances, the rights of creditors. Accordingly, the taking of any actions contemplated by the Banking Act may affect your rights under the Securities, and the value of your Securities may be affected by the exercise of any such powers or threat thereof.

S-47

The circumstances under which the relevant UK resolution authority would exercise its UK bail-in power or other resolution tools under the Banking Act or future legislative or regulatory proposals are uncertain, which may affect the value of your Securities.

There remains significant uncertainty regarding the ultimate nature and scope of the resolution powers under the Banking Act (and such significant uncertainty may exist with respect to any other resolution powers or tools enacted under future legislative or regulatory proposals), as well as the manner in which such powers would affect us and our securities (including the Securities) if such powers were exercised.

For example, although the exercise of the capital instruments and liabilities write-down and conversion power, bail-in tool and other resolution tools under the Banking Act are subject to certain pre-conditions thereunder, there remains uncertainty regarding the specific factors (including, but not limited to, factors outside our control or not directly related to us) which the Bank of England would consider in deciding whether to exercise such powers with respect to us or our securities (including the Securities). In particular, because the Banking Act allows for the Bank of England to exercise its discretion in choosing which resolution tool or tools to apply, it will be difficult to predict whether the exercise of the Bank of England’s resolution powers with respect to any of our securities will result in a principal write-off or conversion to equity. You may not be able to refer to publicly available criteria in order to anticipate a potential exercise of any such resolution powers and consequently its potential effect on us or the Securities. In some circumstances, the relevant UK resolution authority may decide to apply a deferred bail-in, where liabilities are not written down at the start of the resolution but are transferred to a depositary to hold during the bail-in period with the write-down being determined at a later point in the bail-in period.

Accordingly, it is not yet possible to assess the full impact of the exercise of the UK bail-in power pursuant to the Banking Act or otherwise on us, and there can be no assurance that the taking of any actions contemplated therein would not adversely affect your rights, the price or value of your investment in the Securities and/or our ability to satisfy our obligations under the Securities.

We may issue securities senior to, or pari passu with, the Securities or the Conversion Shares.

There is no restriction on the amount of securities that we may issue, incur or guarantee, that rank senior to, or pari passu with, the Securities or the Conversion Shares. In particular, the FSB final standards for TLAC requirements for global systemically important banks (“G-SIBs”) have now been implemented in the UK by the Bank of England using its existing powers under the Banking Act. The Bank of England published its statement of policy on its approach to setting MREL in June 2018, which was updated in December 2021. The updated policy has not changed the MREL calibration framework applicable to G-SIBs which have been subject to end-state MREL requirements from January 1, 2022. The policy also sets out internal MREL requirements that apply to some of our UK subsidiaries. In addition, we are subject to the MREL requirement for G-SIIs under UK CRR, that has applied from June 27, 2019, in addition to the requirements imposed by the Bank of England under the Banking Act. On November 30, 2022, HM Treasury launched a consultation on the technical and legislative changes necessary to facilitate the PRA’s proposed implementation of Basel 3.1 under CP16/22 (CP16/22 having now been superseded by PS17/23 and the second near-final policy statement related to CP16/22 due to be published in 2024, as referred to above). In addition to the Basel 3.1 related measures and other proposals, HM Treasury’s consultation included a proposal to amend the internal MREL provisions in UK CRR to align this with the FSB TLAC requirements. Following this consultation, the UK government passed secondary legislation revoking Article 92b of UK CRR. This provision came into force on January 1, 2024. The Bank of England is no longer subject to the European Union’s decision to apply a fixed internal TLAC requirement of 90% of (hypothetical) external TLAC and will be free to use its discretion to set internal TLAC within the range of 75-90%, consistent with the FSB standards. Any further regulatory developments in this area may in turn impact our ability to make interest payments on the Securities.

For more information on the requirements concerning MREL/TLAC applicable to us, see pages 150 through 156 in the 2023 Form 20-F. Furthermore, the terms of the Indenture permit us (and our subsidiaries) to incur

S-48

additional debt and the Securities will be effectively subordinated to any indebtedness or other liabilities of our subsidiaries (see “—Risks Relating to the Securities—Our holding company structure may mean that our rights to participate in assets of any of our subsidiaries upon its liquidation may be subject to prior claims of some of its creditors, including when we have loaned or otherwise advanced the proceeds received from the issuance of the Securities to such subsidiary”).

In the event of our winding-up prior to a Capital Adequacy Trigger Event, the Securities will be subordinated in right of payment to the claims of Senior Creditors (including those creditors holding any securities we may issue that rank senior to the Securities, such as any securities issued to meet TLAC requirements and any of our capital instruments that qualify as Tier 2 instruments under the Relevant Rules). See “Description of the Securities—Subordination.” After a Capital Adequacy Trigger Event, the Conversion Shares will be subordinated to the claims of our depositors and all of our other creditors, other than claims which by their terms are, or are expressed to be, subordinated to, or pari passu with, our ordinary shares (including those creditors holding any securities we may issue that rank senior to our ordinary shares).

As a result, in the event of our winding-up, you may recover from the value of our assets to satisfy your claims only after our creditors that rank senior to the Securities or the Conversion Shares, as applicable, have been paid in full. In addition, the claims of pari passu creditors may reduce the amount recoverable by you. Therefore, you may lose all or some of your investment in the Securities in the event of our winding-up.

General Risk Factors

Prior to the Conversion Date, you will not be entitled to any rights with respect to our ordinary shares, but will be subject to all changes made with respect to our ordinary shares.

The exercise of voting rights and rights related thereto with respect to our ordinary shares will be possible only after delivery of the Conversion Shares following the Conversion Date and the registration of the person entitled to such Conversion Shares in our share register as an ordinary shareholder with voting rights in accordance with the provisions of, and subject to the limitations provided in, our Articles of Association.

Other changes in law may adversely affect your rights as a securityholder.

Changes in law after the date hereof may affect your rights as a securityholder 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. Moreover, any change in law or regulation that would cause the Securities to cease to qualify in whole or in part as our regulatory capital or to be reclassified, in whole or in part, as a lower quality form of our regulatory capital (other than as a consequence of an Automatic Conversion), could trigger a Capital Disqualification Event (as defined under “Description of the Securities—Redemption—Special Event Redemption”). In addition, any change in law or regulation that results in our having to pay Additional Amounts to you could constitute a Tax Event (as defined under “Description of the Securities—Redemption—Special Event Redemption”) that also may entitle us to redeem the Securities, in whole (but not in part). See “—Risks Relating to the Securities—We may redeem the Securities for certain tax or regulatory reasons or during any Optional Redemption Period” and “Description of the Securities— Redemption—Special Event Redemption.”

In particular, the UK’s withdrawal from the EU continues to create significant political, regulatory and macroeconomic uncertainty. For instance, while the UK’s withdrawal from the EU does not affect the validity of the Banking Act (through which BRRD was implemented), UK and EU law have diverged with respect to certain aspects of recovery and resolution, as well as regulatory capital requirements, and may diverge further, particularly as a result of the enactment of the Financial Services and Markets Act 2023 on June 29, 2023, which gives HM Treasury powers to revoke EU-derived laws (known as “retained EU laws” or “REUL” before the end of 2023 and as of January 1, 2024, known as “assimilated law”) related to financial services (including the UK

S-49

CRR) and replace such assimilated law with a new UK legislative framework. HM Treasury, along with the UK FCA and PRA, have been consulting on the new UK legislative framework. HM Treasury and the PRA are expected to publish consultations, along with draft legislation and rules, on a number of matters relating to the repeal and replacement of UK CRR throughout 2024 and 2025, which, if enacted, would generally be expected to be implemented by firms in 2026. Furthermore, as of January 1, 2024, certain legal effects previously associated with REUL (now referred to as assimilated law) no longer apply, including the supremacy of REUL over other types of conflicting domestic UK law, general principles of EU law (which informed REUL’s interpretation and application) and directly effective EU rights.

Such regulatory changes and the resulting actions taken to address them may include higher capital and additional loss absorbency requirements and increased powers of competent authorities which together may have an adverse impact on the HSBC Group’s, and may therefore affect our, performance and financial condition. It is not possible to predict changes to legislation or regulatory rulemaking or the ultimate consequences of any such changes to the HSBC Group or the securityholders, which could be material to the rights of securityholders and/or our ability to satisfy our obligations under the Securities.

Moreover, certain requirements of the Capital Instruments Regulations form the basis for the structuring of the Securities. These requirements may cease to apply in the UK in its current form, including as a result of the implementation of prudential requirements based on Basel 3.1 in the UK, which may result in some changes to UK prudential requirements. This may affect the regulatory capital treatment of the Securities, which could trigger a Capital Disqualification Event, and may reduce the liquidity of the Securities while ongoing uncertainty exists.

Such legislative and regulatory uncertainty could also affect the liquidity of the Securities and/or your ability to accurately value them, 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 under “—Risks Relating to the Securities—The circumstances under which the relevant UK resolution authority would exercise its UK bail-in power or other resolution tools under the Banking Act or future legislative or regulatory proposals are uncertain, which may affect the value of your Securities,” could have on the Securities.

As a result of your receiving Conversion Shares upon a Capital Adequacy Trigger Event, you are particularly exposed to changes in the market price of our ordinary shares.

Many investors in convertible or exchangeable securities seek to hedge their exposure in the underlying equity securities at the time of acquisition of the convertible or exchangeable securities, often through short selling of the underlying equity securities or through similar transactions. Prospective investors in the Securities may look to sell our ordinary shares in anticipation of taking a position in, or during the term of, the Securities. This could drive down the price of our ordinary shares. Since the Securities will mandatorily convert into a fixed number of Conversion Shares upon a Capital Adequacy Trigger Event, the price of the Conversion Shares may be more volatile if we are trending toward a Capital Adequacy Trigger Event.

You may be subject to disclosure obligations and/or may need approval from our regulator under certain circumstances.

As you may receive Conversion Shares if a Capital Adequacy Trigger Event occurs, an investment in the Securities may result in your having to comply with certain disclosure 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, we (and the FCA) must be notified by a person when the percentage of voting rights in us 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 UK, the United States and other jurisdictions, ownership of the

S-50

Securities (or the Conversion Shares) above certain levels may require you to obtain regulatory approval or subject you 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, you should consult your legal advisers as to the terms of the Securities, in respect of your existing shareholding and the level of holding you would have if you receive Conversion Shares following a Capital Adequacy Trigger Event.

The historical levels of the rates applicable to U.S. Treasury securities are not an indication of their future levels.

In the past, the rates applicable to U.S. Treasury securities have experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the rates applicable to U.S. Treasury Securities (and, therefore, the Reference Rate) are not necessarily indicative of future levels. Any historical upward or downward trend in the rates applicable to U.S. Treasury securities (and the Reference Rate) is not an indication that such rates are more or less likely to increase or decrease at any time during an interest period, and you should not take the historical levels of the rates applicable to U.S. Treasury securities (and the Reference Rate) as an indication of their future performance.

The Securities are not bank deposits.

An investment in the Securities is not equivalent to an investment in a bank deposit and carries risks that are very different from the risk profile of such a deposit.

The issue price, interest rate and yield to maturity of the Securities are expected to reflect the additional risks borne by investors therein when compared to those of depositors. For example, the Securities do not benefit from any protection provided pursuant to the UK law which implemented the EU Deposit Guarantee Scheme Directive (2014/49/EU), such as the UK Financial Services Compensation Scheme. Therefore, if we become insolvent or default on our obligations, investors could lose their entire investment. Additionally, the Securities may be subject to the capital instruments and liabilities write-down and conversion power (which does not apply to ordinary bank deposits) and the Securities would be subject to the bail-in tool before it is applied to bank deposits (to the extent that such deposits are subject to the bail-in tool at all). See “—Risks Relating to the Securities—The Securities are the subject of the UK bail-in power, which may result in your Securities being written down to zero or converted into other securities, including unlisted equity securities.”

The Securities constitute a new issue of securities by us and we cannot guarantee that an active public market for the Securities will develop or be sustained.

The Securities will constitute a new issue of securities by us. Prior to our present issuance of Securities, there will have been no public market for the Securities. Even though the Securities are expected to have greater liquidity than a bank deposit given that bank deposits are generally not transferable, there can be no assurance that an active public market for the Securities will develop. See “—Risks Relating to the Securities—The Securities are not bank deposits.” Although application has been made to Euronext Dublin for the Securities to be admitted to the Official List and to trading on the GEM (the exchange-regulated market of Euronext Dublin), there can be no assurance that an active public market for the Securities will develop and, if such a market were to develop, we and the underwriters are under no obligation to maintain such a market. In addition, the ability of the underwriters to make a market in the Securities may be impacted by changes in regulatory requirements applicable to the marketing, holding and trading of, and issuing quotations with respect to, the Securities. The liquidity and the market prices for the Securities can be expected to vary with changes in market and economic conditions and our financial condition and prospects and other factors that generally influence the market prices of securities.

S-51

Our credit ratings may not reflect all risks of an investment in the Securities, and changes to any credit rating assigned to us or the Securities may affect the market value of the Securities.

Our credit ratings or those assigned to the Securities may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or market value of, the Securities. A credit rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn by the rating agency at any time in its sole discretion.

Any rating assigned to us 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. Moreover, the rating agencies that currently, or may in the future, publish a rating for us or the Securities may change the methodologies that they use for analyzing securities with features similar to the Securities. Ratings may be impacted by a number of factors that can change over time, including the credit rating agency’s assessment of: (i) our strategy and management’s capability; (ii) our financial condition, including in respect of capital, funding and liquidity; (iii) competitive, economic, legal and regulatory conditions in our key markets, including those markets where we have large exposures or on which our operating results, including revenues, are substantially dependent; (iv) the level of political support for the industries in which we operate; (v) legal and regulatory frameworks affecting our legal structure, business activities and the rights of our creditors; and (vi) the impact of the current macroeconomic environment, the Russia-Ukraine war and the Israel-Hamas war.

There can be no assurance that the rating agencies will maintain the current ratings or outlook assigned to us or the Securities.

Real or expected downgrades, suspensions or withdrawals of credit ratings assigned to us or the Securities could cause the liquidity or trading prices of the Securities to decline significantly. Additionally, any uncertainty about the extent of any anticipated changes to the credit ratings assigned to us or the Securities may adversely affect the market value of the Securities.

The Securities may be assigned a credit rating below investment grade in the future, in which case the Securities will be subject to the risks associated with non-investment grade securities.

The Securities are expected to be assigned a credit rating slightly above investment grade. However, rating agencies that are expected to assign ratings to the Securities may adopt methodology changes that may result in lowering the credit rating of the Securities to below investment grade. Moreover, after the Issue Date, we may seek a credit rating on the Securities from additional rating agencies, any of which may assign a credit rating to the Securities below investment grade, including due to methodology changes between the Issue Date and the date the credit rating is assigned. See “Our credit ratings may not reflect all risks of an investment in the Securities, and changes to any credit rating assigned to us or the Securities may affect the market value of the Securities.”

If the Securities are not considered to be investment grade securities, they will be subject to a higher risk of price volatility than more highly rated securities. Furthermore, increases in leverage or deteriorating outlooks for us or volatile markets could lead to a significant deterioration in market prices of below-investment grade rated securities.

You may not be entitled to receive U.S. dollars in a winding-up.

If you are entitled to any recovery with respect to the Securities in any winding-up, you might not be entitled in those proceedings to a recovery in U.S. dollars and might be entitled only to a recovery in pounds sterling or any other lawful currency of the UK. In addition, under current English law, our liability to you would have to be converted into pounds sterling or any other lawful currency of the UK at a date close to the commencement of proceedings against us and you would be exposed to currency fluctuations between that date and the date you receive proceeds pursuant to such proceedings, if any.

S-52

You will be responsible for any taxes following an Automatic Conversion.

Neither we nor any member of the HSBC Group will be liable for any taxes or duties (including, without limitation, any capital, stamp, issue and registration or transfer taxes or duties) arising on conversion or that may arise or be paid as a consequence of the issue and delivery of Conversion Shares following an Automatic Conversion. You must pay any taxes or duties (including, without limitation, any capital, stamp, issue and registration and/or transfer taxes or duties) arising on conversion in connection with the issue and delivery of Conversion Shares to the Conversion Shares Depository on your behalf and you must pay all, if any, such taxes or duties arising by reference to any disposal or deemed disposal of your Securities or interest therein (except for any taxes or duties arising on delivery or transfer of Conversion Shares to a purchaser in any Conversion Shares Offer).

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

The Conversion Price and the Conversion Shares Offer Price are subject to adjustment in certain circumstances, as described under “Description of the Securities—Anti-Dilution.” 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 “Taxation—United States Federal Income Tax Considerations” for a further discussion of these U.S. federal tax implications.

Our gross-up obligation under the Securities is limited to payments of interest.

Our obligation to pay Additional Amounts in respect of any withholding or deduction in respect of UK taxes under the terms of the Securities applies only to payments of interest in respect of the Securities and not to payments of principal. Accordingly, we would not be required to pay any Additional Amounts under the terms of the Securities to the extent any such withholding or deduction applied to payments of principal. In such circumstances, you may receive less than the full amount of principal due in respect of the Securities, and the market value of the Securities may be adversely affected. See “Description of Contingent Capital Securities—Additional Amounts” in the accompanying prospectus.

DESCRIPTION OF THE SECURITIES

The following summary description of certain material terms and provisions of the Securities supplements the description of certain terms and provisions of the contingent convertible securities of any series set forth in the accompanying prospectus under the heading “Description of Contingent Convertible Securities.” The terms described here, together with the relevant terms of contingent convertible securities contained in the accompanying prospectus, constitute a description of the material terms of the Securities. In cases of inconsistency between the terms described here and the relevant terms of the prospectus, the terms presented here will apply and replace those described in the prospectus.

The Securities will constitute a series of contingent convertible securities issued under the indenture dated as of August 1, 2014 (as amended and supplemented from time to time) among us, The Bank of New York Mellon, London Branch, as trustee, and HSBC Bank USA, National Association, as paying agent and registrar, the form of which is filed as an exhibit to our registration statement on Form F-3 (the “Registration Statement”). The indenture will be supplemented and amended by a fifteenth supplemental indenture, with respect to the 2030 Securities, and a sixteenth supplemental indenture, with respect to the 2034 Securities, both of which are expected to be entered into on the Issue Date, in each case, among us, the trustee and HSBC Bank USA, National Association, as paying agent, registrar and calculation agent (the indenture, together with the fifteenth supplemental indenture or the sixteenth supplemental indenture, as applicable, the “Indenture”), which will be filed as an exhibit to a report on Form 6-K on or about September 11, 2024, which will be incorporated by reference in the Registration Statement.

If you purchase the Securities, your rights will be determined by the Securities, the Indenture and the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), unless your Securities are converted to Conversion Shares after a Capital Adequacy Trigger Event as described under “—Automatic Conversion Upon Capital Adequacy Trigger Event,” in which case your rights will be determined in accordance with the terms of our ordinary shares as described in the accompanying prospectus under “Description of Ordinary Shares.” You can read the Indenture and the form of Securities at the location listed under “Where You Can Find More Information About Us.”

The Indenture and the Securities will be governed by, and construed in accordance with, the laws of the State of New York, except that the subordination provisions of the Indenture and of the Securities (see “—Subordination”) and the waiver of set-off provisions of the Indenture and the Securities (see “Description of Contingent Capital Securities—No Right of Set-Off by Holders” in the accompanying prospectus) will be governed by, and construed in accordance with, the laws of England and Wales.

The 2030 Securities and the 2034 Securities will be issued in an aggregate principal amount of $1,350,000,000 and $1,150,000,000, respectively. The Securities will have no fixed maturity or fixed redemption date.

The Securities will be issued only in registered form in minimum denominations of $200,000 and in integral multiples of $1,000 in excess thereof.

Interest

General

From (and including) the Issue Date to (but excluding) March 11, 2030, the interest rate on the 2030 Securities will be 6.875% per annum (the “2030 Securities Initial Interest Rate”). From (and including) each 2030 Securities Reset Date (as defined below) to (but excluding) the next following 2030 Securities Reset Date, the applicable per annum interest rate will be equal to the sum of the applicable Reference Rate on the relevant Reset Determination Date and 3.298% (the “2030 Securities Margin”).

From (and including) the Issue Date to (but excluding) September 11, 2034, the interest rate on the 2034 Securities will be 6.950% per annum (the “2034 Securities Initial Interest Rate”). From (and including) each

S-57

2034 Securities Reset Date (as defined below) to (but excluding) the next following 2034 Securities Reset Date, the applicable per annum interest rate will be equal to the sum of the applicable Reference Rate on the relevant Reset Determination Date and 3.191% (the “2034 Securities Margin”).

With respect to the 2030 Securities, interest will reset on March 11, 2030 and each fifth anniversary date thereafter (each such date, a “2030 Securities Reset Date”).

With respect to the 2034 Securities, interest will reset on September 11, 2034 and each fifth anniversary date thereafter (each such date, a “2034 Securities Reset Date”).

A “Reset Date” means either a “2030 Securities Reset Date” or a “2034 Securities Reset Date”, as applicable.

The “Initial Interest Rate” means either the 2030 Securities Initial Interest Rate or the 2034 Securities Initial Interest Rate, as applicable, and the “Margin” means either the 2030 Securities Margin or the 2034 Securities Margin, as applicable.

A “Reset Determination Date” is the second business day immediately preceding a Reset Date.

Each period from (and including) a 2030 Securities Reset Date to (but excluding) the following 2030 Securities Reset Date will be a “2030 Securities Reset Period.”

Each period from (and including) a 2034 Securities Reset Date to (but excluding) the following 2034 Securities Reset Date will be a “2034 Securities Reset Period.”

“Reset Period” means either a 2030 Securities Reset Period or a 2034 Securities Reset Period, as applicable.

“Reference Rate” means, with respect to any Reset Period for which such rate applies:

(1) the rate per annum (expressed as a decimal) equal to the yield which represents the average for the week immediately prior to the related Reset Determination Date in the most recent H.15, (a) under the caption “Treasury Constant Maturities” and (b) for the maturity of five years;

(2) if such release (or any successor release) is not published during the week immediately prior to the related Reset Determination Date or does not contain such yields, the Reference Treasury Rate for such Reset Period; or

(3) if the Reference Rate cannot be determined, for whatever reason, as described under (1) or (2) above, “Reference Rate” means the rate per annum (expressed as a decimal) equal to the yield on U.S. Treasury securities having a maturity of five years as set forth in the most recent H.15 under the caption “Treasury constant maturities” for the maturity of five years at 5:00 p.m. (New York City time) on the last available date preceding the related Reset Determination Date on which such rate was set forth in such release (or any successor release).

The Reference Rate shall be calculated by the calculation agent.

“H.15” means the weekly statistical release designated as such and published by the Board of Governors of the United States Federal Reserve System, or any successor or replacement publication that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity, and “most recent H.15” means the H.15 published closest in time but prior to 5:00 p.m. (New York City time) on the applicable Reset Determination Date.

“Reference Treasury” means, in respect of a Reset Period, the U.S. Treasury security or securities selected by us (following, where practicable, consultation with an investment bank or financial institution determined to

S-58

be appropriate by us (which may be the calculation agent)) (i) with a maturity date on or about the last day of such Reset Period and (ii) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities denominated in U.S. dollars and having a maturity of five years.

“Reference Treasury Rate” means, with respect to any Reset Period, the rate per annum (expressed as a decimal) equal to the yield to maturity (on the relevant day count basis) of the Reference Treasury, assuming a price for the Reference Treasury (expressed as a percentage of its principal amount) equal to the Reference Treasury Price on the relevant Reset Determination Date.

“Reference Treasury Price” means, with respect to any Reset Determination Date, (i) the arithmetic average of the Reference Treasury Dealer Quotations for such Reset Determination Date, after excluding the highest quotation (or, in the event of more than one highest quotation, one of the highest) and lowest quotation (or, in the event of more than one lowest quotation, one of the lowest), or (ii) if fewer than five but more than one such Reference Treasury Dealer Quotations are received, the arithmetic average of all such quotations, or (iii) if only one such Reference Treasury Dealer Quotation is received, then such quotation; each as quoted in writing to the calculation agent by a Reference Treasury Dealer.

“Reference Treasury Dealer” means, with respect to any Reset Determination Date, each of up to five banks selected by us (following, where practicable, consultation with an investment bank or financial institution determined to be appropriate by us (which may be the calculation agent)), or the affiliates of such banks, which are (i) primary U.S. Treasury securities dealers, and their respective successors, or (ii) market makers in pricing corporate bond issues denominated in U.S dollars.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Reset Determination Date, the arithmetic average, as determined by the calculation agent, of the bid and offered prices for the applicable Reference Treasury, expressed in each case as a percentage of its principal amount, quoted by the applicable Reference Treasury Dealer at 11:00 a.m. (New York City time), on such Reset Determination Date.

We will promptly give notice of the determination of the Reference Rate to the trustee, the paying agent and the securityholders; provided that failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

Unless otherwise specified, all percentages resulting from any calculation in connection with any interest rate on the Securities shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (for example, 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655)), and all U.S. dollar amounts would be rounded to the nearest cent, with one-half cent being rounded upward.

All determinations and any calculations made by the calculation agent for the purposes of calculating the applicable Reference Rate will be conclusive and binding on the securityholders, us, the trustee and the paying agent, absent manifest error. The calculation agent will not be responsible to us, the securityholders or any third party for any failure of the Reference Treasury Dealers 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 Treasury Dealer which subsequently may be found to be incorrect or inaccurate in any way.

Subject to cancellation or deemed cancellation as described under “—Interest—Interest Cancellation,” interest on the 2030 Securities, if any, will be payable in two semi-annual installments in arrear on March 11 and September 11 of each year, beginning on March 11, 2025.

Subject to cancellation or deemed cancellation as described under “—Interest—Interest Cancellation,” interest on the 2034 Securities, if any, will be payable in two semi-annual installments in arrear on March 11 and September 11 of each year, beginning on March 11, 2025.

S-59

The regular record dates for the Securities will be the 15th calendar day preceding each interest payment date, whether or not a business day. Interest on the Securities, if any, will be calculated on the basis of twelve 30-day months or, in the case of an incomplete month, the actual number of days elapsed, in each case assuming a 360-day year.

If any scheduled interest payment date is not a business day, we may pay interest (if any) on the next succeeding business day, but interest on that payment will not accrue during the period from and after the scheduled interest payment date. If the date of redemption or repayment is not a business day, we may pay interest (if any) and principal on the next succeeding business day, but interest on that payment will not accrue during the period from and after the date of redemption or repayment.

If any Reset Date is not a business day, the Reset Date will occur on the next succeeding business day (the “Adjusted Reset Date”). For the avoidance of doubt, if the Reset Date is not a business day and accordingly the Reset Date occurs on the Adjusted Reset Date, the semi-annual payment of interest (if any) on the next interest payment date will reflect interest for the entire interest period (including any portion of such interest period occurring between the originally scheduled Reset Date and the Adjusted Reset Date) at the interest rate determined based on the Adjusted Reset Date, and not at the interest rate that applied to the immediately preceding semi-annual interest period.

Interest Cancellation

Interest on the Securities will be due and payable on an interest payment date only to the extent it is not cancelled or deemed to have been cancelled (in each case, in whole or in part) in accordance with the provisions described below. Any interest cancelled or deemed to have been cancelled (in each case, in whole or in part) will not be due and will not accumulate or be payable at any time thereafter, and the securityholders will have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation. For the avoidance of doubt, any interest payments that have been cancelled or deemed to have been cancelled will not be payable if the Securities are redeemed as described under “—Redemption.”

Discretionary Interest Payments

Interest on the Securities will be due and payable at our sole discretion, and we will 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 (the “Discretionary Interest Payment Right”). If we do not make an interest payment in respect of the Securities on the relevant interest payment date (or if we elect to make a payment of a portion, but not all, of such interest payment), such non-payment will evidence the exercise of our 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) will not be due and payable. For the avoidance of doubt, if we provide notice to cancel a portion, but not all, of an interest payment in respect of the Securities, and subsequently we do not make a payment of the remaining portion of such interest payment on the relevant interest payment date, such non-payment will evidence the exercise of our discretion to cancel such remaining portion of such interest payment, and accordingly such remaining portion of the interest payment will also not be due and payable.

The Securities will rank senior to our ordinary shares, as described under “—Subordination.” It is the current intention of our board of directors to take into account the relative ranking in our capital structure of our ordinary shares and outstanding additional Tier 1 securities whenever exercising its discretion to declare dividends on the former or to cancel interest on the latter. However, our board of directors may depart from this policy at any time in its sole discretion.

Restrictions on Interest Payments

Without prejudice to the Discretionary Interest Payment Right or the prohibition contained in Rule 4.3(2) of Chapter 4 on the making of payments on the Securities before the Maximum Distributable Amount has been

S-60

calculated, subject to the extent permitted in the following paragraph in respect of partial interest payments in respect of the Securities, we will not make an interest payment on any interest payment date (and such interest payment will therefore be deemed to have been cancelled and thus will not be due and payable on such interest payment date) if:

We may, in our 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 restrictions in the preceding paragraph. For the avoidance of doubt, the portion of interest not paid on the relevant interest payment date will be deemed to have been cancelled and thus will not be due and payable on such interest payment date.

Agreement to Interest Cancellation

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge and agree that:

Notice of Interest Cancellation

If practicable, we will provide notice of any cancellation or deemed cancellation of interest (in each case, in whole or in part) to the securityholders through the Depository Trust Company (“DTC”) (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities) and to the trustee and the paying agent directly on or prior to the relevant interest payment date. If practicable, we will endeavor to do so at least five business days prior to the relevant interest payment date. Failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed cancellation of interest (and accordingly, such interest will not be due and payable), or give the securityholders any rights as a result of such failure.

Redemption

The Securities will not be redeemable at the option of the securityholders at any time. The Securities will not be subject to any sinking fund or mandatory redemption.

S-61

Optional Redemption

The 2030 Securities may be redeemed in whole (but not in part) at our option in our sole discretion on any business day during any 2030 Securities Optional Redemption Period (a “2030 Securities Optional Redemption Date” and such redemption, a “2030 Securities Optional Redemption”), at a redemption price equal to 100% of the principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption (which interest will exclude any interest that is cancelled or deemed to have been cancelled as described under “—Interest—Interest Cancellation”).

The 2034 Securities may be redeemed in whole (but not in part) at our option in our sole discretion on any business day during any 2034 Securities Optional Redemption Period (a “2034 Securities Optional Redemption Date” and such redemption, a “2034 Securities Optional Redemption”), at a redemption price equal to 100% of the principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption (which interest will exclude any interest that is cancelled or deemed to have been cancelled as described under “—Interest—Interest Cancellation”).

“2030 Securities Optional Redemption Period” means the period commencing on the date falling six calendar months prior to a 2030 Securities Reset Date and ending on such 2030 Securities Reset Date (both dates inclusive).

“2034 Securities Optional Redemption Period” means the period commencing on the date falling six calendar months prior to a 2034 Securities Reset Date and ending on such 2034 Securities Reset Date (both dates inclusive).

“Optional Redemption Period” means either the 2030 Securities Optional Redemption Period or the 2034 Securities Optional Redemption Period, as applicable.

“Optional Redemption Date” means either a 2030 Securities Optional Redemption Date or a 2034 Securities Optional Redemption Date, as applicable.

“Optional Redemption” means either a 2030 Securities Optional Redemption or a 2034 Securities Optional Redemption.

Any redemption of the Securities is subject to the restrictions described under “—Redemption—Redemption Conditions.”

Special Event Redemption

We may redeem the Securities in whole (but not in part) at our option in our sole discretion upon the occurrence of a Tax Event or a Capital Disqualification Event (each, a “Special Event”), at a redemption price equal to 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption (which interest will exclude any interest that is cancelled or deemed to have been cancelled as described under “—Interest— Interest Cancellation”). Any redemption will be subject to the conditions described under “—Redemption—Redemption Conditions.”

A “Tax Event” will be deemed to have occurred with respect to the Securities if at any time we determine that as a result of a change in, or amendment to, the laws of a Taxing Jurisdiction, including any treaty to which the relevant Taxing Jurisdiction is a party, or a change in an official application or interpretation of those laws on or after the Issue Date, including a decision of any court or tribunal that becomes effective on or after the Issue Date:

S-62

Subject only to our obligation to use such endeavors as provided in paragraph (b), it will be sufficient for us to deliver to the trustee an officer’s certificate stating that a Tax Event has occurred and is continuing and setting out the details thereof, as well as any opinion or certificate of an independent legal adviser on which such officer’s certificate is based. For these purposes, the trustee and the paying agent will accept such officer’s certificate without further enquiry as sufficient evidence of the existence of such circumstances and such officer’s certificate will be conclusive and binding on the securityholders.

A “Capital Disqualification Event” will be deemed to have occurred if we determine, at any time after the Issue Date, there is a change in the regulatory classification of the Securities that results or will result in either their (i) exclusion in whole or in part from the HSBC Group’s regulatory capital (other than as a consequence of an Automatic Conversion); or (ii) reclassification in whole or in part as a form of the HSBC Group’s regulatory capital that is lower than additional Tier 1 capital.

Redemption Conditions

Notwithstanding anything to the contrary in the Indenture or the Securities, we may only redeem the Securities if (i) we have obtained the Relevant Supervisory Consent, (ii) prior to the fifth anniversary of the Issue Date, if the Relevant Rules so oblige, we have demonstrated to the satisfaction of the Relevant Regulator that (x) the Special Event was not reasonably foreseeable at the Issue Date and (y) in the case of a Tax Event, such Tax Event was material or (z) in any relevant circumstances, we have demonstrated to the satisfaction of the Relevant Regulator that we have (or will have), before or at the same time as such redemption, replaced the Securities with our own funds instruments of equal or higher quality at terms that are sustainable for our income capacity, and the Relevant Regulator has permitted such action on the basis of the determination that it would be beneficial from a prudential point of view and justified by exceptional circumstances, (iii) we have complied with any alternative or additional pre-conditions to redemption, as applicable, set out in the Relevant Rules and (iv) we have provided notice as described under “—Redemption—Notice of Redemption.”

Any redemption of the Securities will be subject to our giving (i) in the case of an Optional Redemption, not less than 10 days’, nor more than 60 days’, prior notice to the securityholders, and (ii) in the case of any other redemption, not less than 30 days’, nor more than 60 days’, prior notice to the securityholders, in each case via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities); provided, however, that in the case of a Tax Event, no notice of redemption will be given earlier than 90 days prior to the earliest date on which we would be obliged to pay Additional Amounts were a payment in respect of the Securities then due. Such notice will specify our election to redeem the Securities and the redemption date and will be irrevocable except in the limited circumstances described in the following paragraph.

A redemption notice will be automatically rescinded and will have no force and effect, and no redemption amount will be due and payable, if either (x) the Solvency Condition is not satisfied in respect of the relevant redemption amount on the applicable redemption date, (y) a Capital Adequacy Trigger Event occurs prior to the applicable redemption date (in which case, an Automatic Conversion will occur as described under “—Automatic Conversion Upon Capital Adequacy Trigger Event”) or (z) the relevant UK resolution authority exercises its UK bail-in power prior to the applicable redemption date. If a redemption notice is rescinded for any of the reasons described in the previous sentence, we will promptly deliver notice to the securityholders via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities), specifying the occurrence of the relevant event.

Purchases

Members of the HSBC Group may purchase, repurchase or otherwise acquire any of the outstanding Securities at the same or differing prices in the open market, negotiated transactions or otherwise without giving prior notice to or obtaining any consent from securityholders, in accordance with the Relevant Rules and subject to obtaining the Relevant Supervisory Consent. For the avoidance of doubt, the Securities may be repurchased by members of the HSBC Group for market-making purposes in accordance with any permission given by the Relevant Regulator pursuant to the Relevant Rules within the limits prescribed in such permission.

Automatic Conversion Upon Capital Adequacy Trigger Event

Automatic Conversion

A “Capital Adequacy Trigger Event” will occur if at any time the non-transitional CET1 Ratio is less than 7.0%. Whether a Capital Adequacy Trigger Event has occurred at any time will be determined by us, the Relevant Regulator or any agent of the Relevant Regulator appointed for such purpose by the Relevant Regulator.

If a Capital Adequacy Trigger Event occurs, then an Automatic Conversion will occur without delay (but no later than one month following the date on which it is determined such Capital Adequacy Trigger Event has occurred), as described under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Procedure.” An “Automatic Conversion” is the irrevocable and automatic release of all of our obligations under the Securities in consideration of our issuance of the Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) on the date on which the Automatic Conversion will take place, or has taken place, as applicable (such date, the “Conversion Date”), in accordance with the terms of the Securities and the Indenture, and under no circumstances will such released obligations be reinstated.

Subject to the conditions described further under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Procedure,” following a Capital Adequacy Trigger Event, we expect the Conversion Shares Depository to deliver to the securityholders on the Settlement Date either (i) Conversion Shares or (ii) if we elect, in our sole

S-64

and absolute discretion, that a Conversion Shares Offer be made, the Conversion Shares Offer Consideration. For further information about Conversion Shares and the Conversion Shares Offer, see “—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares” and “—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares Offer,” respectively.

Effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of our winding-up or the appointment of an administrator for our administration as described under “—Subordination,” the securityholders will not have any rights against us with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on, or in respect of, the Securities, in each case that is not due and payable, which liabilities will be automatically released. Accordingly, the principal amount of the Securities will equal zero at all times thereafter and any interest will be cancelled or deemed to have been cancelled at all times thereafter and will not be due and payable (see “—Interest—Interest Cancellation”), including 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. Although the principal amount of each Security will equal zero after a Capital Adequacy Trigger Event for the avoidance of doubt, the Tradable Amount will remain unchanged as a result of the Automatic Conversion.

Effective upon, and following, an Automatic Conversion, all of our obligations under the Securities will be irrevocably and automatically released in consideration of our issuance of the Conversion Shares to the Conversion Shares Depository on the Conversion Date, and under no circumstances will such released obligations be reinstated. With effect from the Conversion Date, the securityholders will have recourse only to the Conversion Shares Depository for the delivery to them of Conversion Shares or, if we elect that a Conversion Shares Offer be made, of any Conversion Shares Offer Consideration to which such securityholders are entitled. If we fail to issue and deliver the Conversion Shares to the Conversion Shares Depository in accordance with the terms of the Securities, the securityholders’ only right against us will be to claim to have such Conversion Shares issued to the Conversion Shares Depository. If we have been unable to appoint a Conversion Shares Depository, we will effect, by means we deem reasonable under the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to the securityholders directly), the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the securityholders, and such issuance will irrevocably and automatically release all of the our obligations under the Securities as if the Conversion Shares had been issued to the Conversion Shares Depository.

Following the issuance of the Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date, the Securities will remain in existence until the applicable Cancellation Date for the sole purpose of evidencing the securityholders’ right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities).

The Securities will not be convertible into Conversion Shares at the option of the securityholders at any time.

Conversion Shares

“Conversion Shares” means our ordinary shares to be issued to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) following an Automatic Conversion.

The number of Conversion Shares to be issued to the Conversion Shares Depository on behalf of the securityholders (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date will equal the quotient obtained by dividing the (i) aggregate principal amount of the Securities then outstanding immediately prior to the Automatic Conversion on the Conversion Date (the “Outstanding Amount”)

S-65

by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The Conversion Price is fixed initially at $3.550 per Conversion Share and is subject to certain anti-dilution adjustments, as described under “—Anti-dilution—Adjustment of Conversion Price and Conversion Shares Offer Price” (the “Conversion Price”). On the Issue Date, the Conversion Price will be equal to the Conversion Shares Offer Price (based on an exchange rate of £1.00 = $1.3148). The number of Conversion Shares to be held by the Conversion Shares Depository for the benefit of a securityholder will equal the product obtained by multiplying (i) the number of Conversion Shares thus calculated by (ii) the quotient obtained by dividing (x) the Tradable Amount held by such securityholder on the Conversion Date by (y) the Outstanding Amount, such product to be rounded down, if necessary, to the nearest whole number of Conversion Shares. For the avoidance of doubt, fractions of Conversion Shares will not be issued following an Automatic Conversion and no cash payment will be made in lieu thereof.

The Conversion Shares initially will be registered in the name of the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) (which will hold the Conversion Shares on behalf of the securityholders), and each securityholder will be deemed to have irrevocably directed us 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 Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) will hold the Conversion Shares on behalf of the securityholders, who will be entitled to direct the Conversion Shares Depository or such other relevant recipient, as applicable, to exercise on their behalf all rights of one of our ordinary shareholders (including voting rights and rights to receive dividends); provided that the securityholders will not have any rights to sell or otherwise transfer the Conversion Shares until such time as the Conversion Shares have been delivered to the securityholders in accordance with the procedures described further under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Procedure—Settlement Procedure.”

While any Security remains outstanding, we will at all times keep available for issue, free from pre-emptive or other preferential rights, sufficient ordinary shares to enable an Automatic Conversion to be satisfied in full. 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 securityholder will not be entitled to receive) any rights, distributions or payments, the entitlement to which falls prior to the Conversion Date.

If a Qualifying Takeover Event occurs, and the Conversion Date falls on or after the QTE Effective Date, then in such case Approved Entity Shares will be issued by the Approved Entity to the Conversion Shares Depository instead of Conversion Shares with the same effect as if Conversion Shares had been issued, as described, and subject to the conditions specified, under “—Qualifying Takeover Event.”

Conversion Shares Offer

We may, in our sole and absolute discretion and following the occurrence of an Automatic Conversion, elect in the Conversion Shares Offer Notice that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of our ordinary shareholders at a cash price per Conversion Share equal to the Conversion Shares Offer Price (the “Conversion Shares Offer”). The Conversion Shares Offer Price is fixed initially at £2.70 per Conversion Share and is subject to certain anti-dilution adjustments, as described under “—Anti-dilution—Adjustment of Conversion Price and Conversion Shares Offer Price” (the “Conversion Shares Offer Price”). On the Issue Date, the Conversion Shares Offer Price and the Conversion Price will be equal (based on an exchange rate of £1.00 = $1.3148).

Upon completion of the Conversion Shares Offer, we or the Conversion Shares Depository will provide notice to the securityholders of the composition of the Conversion Shares Offer Consideration (including the pro rata cash component (as defined below) thereof, if any) per $1,000 Tradable Amount. The “Conversion Shares

S-66

Offer Consideration” in respect of each Security will be, (i) if all the Conversion Shares are sold in the Conversion Shares Offer, the pro rata share of the cash proceeds from such sale attributable to such Security converted from pounds sterling (or any such other currency in which our ordinary shares are denominated) into U.S. dollars at the Prevailing Rate as of the date that is three Depository Business Days prior to the relevant Settlement Date as determined by the Conversion Shares Depository (less the pro rata share of any foreign exchange transaction costs) (the “pro rata cash component”), (ii) if some but not all of the Conversion Shares are sold in the Conversion Shares Offer, (x) the pro rata cash component and (y) 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 (the “pro rata Conversion Shares component”), and (iii) if no Conversion Shares are sold in a Conversion Shares Offer, the relevant Conversion Shares attributable to such Security rounded down to the nearest whole number of Conversion Shares, subject in the case of (i) and (ii)(x) above to deduction from any such cash proceeds 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 any interest in the Conversion Shares to the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) in order for the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) to conduct the Conversion Shares Offer.

We may, on behalf of the Conversion Shares Depository, appoint an agent to act as placement or other agent to facilitate the Conversion Shares Offer (a “Conversion Shares Offer Agent”). If we elect a Conversion Shares Offer to be conducted, the Conversion Shares Offer Period, during which time the Conversion Shares Offer may be made, will end no later than 40 business days following the delivery of the Conversion Shares Offer Notice.

Any Conversion Shares Offer will be made subject to applicable laws and regulations in effect at the relevant time and will be conducted, if at all, only to the extent that we, in our sole and absolute discretion, determine that the Conversion Shares Offer is practicable. We or the purchasers of the Conversion Shares sold in any Conversion Shares Offer will bear the costs and expenses of any Conversion Shares Offer (with the exception 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 any interest in the Conversion Shares to the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) in order for the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) to conduct the Conversion Shares Offer), including the fees of the Conversion Shares Offer Agent, if any.

We reserve the right, in our sole and absolute discretion, to terminate the Conversion Shares Offer at any time during the Conversion Shares Offer Period by providing at least three business days’ notice to the trustee and the paying agent directly and to the securityholders via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities), and, if we do so, we may, in our sole and absolute discretion, take steps (including, without limitation, changing the Suspension Date) to deliver to the securityholders (or the custodian, nominee, broker or other representative thereof) the Conversion Shares at a time that is earlier than the time at which such securityholders (or the custodian, nominee, broker or other representative thereof) would have otherwise received the Conversion Shares Offer Consideration, had the Conversion Shares Offer been completed.

The pro rata cash component will be payable by the Conversion Shares Depository to the securityholders (or the custodian, nominee, broker or other representative thereof) whether or not the Solvency Condition is satisfied.

We currently expect that in determining whether or not a Conversion Shares Offer will be conducted and, if one is to be conducted, how and to whom such Conversion Shares Offer will be made, our board of directors would, in accordance with their duties, have regard to a variety of matters, including, without limitation, the

S-67

interests of our ordinary shareholders, taken as a whole, and the potential impact of a Conversion Shares Offer on our 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 us to undertake a Conversion Shares Offer on the terms set out herein, will preclude us from undertaking a rights issue or other equity issuance at any time on such terms as we deem appropriate, at our sole discretion, including—for the avoidance of doubt—the offer of our ordinary shares at or below the Conversion Shares Offer Price. Moreover, there can be no assurance that the Conversion Shares Offer would be conducted on an SEC-registered basis.

Procedure

Automatic Conversion Procedure

We will (x) immediately inform the Relevant Regulator of the occurrence of a Capital Adequacy Trigger Event and (y) deliver an Automatic Conversion Notice on or as soon as practicable after the date on which it is determined such Capital Adequacy Trigger Event has occurred.

The “Automatic Conversion Notice” will be a written notice to be delivered by us to the trustee and the paying agent directly and to the securityholders via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities) specifying (i) that a Capital Adequacy Trigger Event has occurred, (ii) the Conversion Date or expected Conversion Date, (iii) that we have the option, at our sole and absolute discretion, to elect that a Conversion Shares Offer be conducted and that we will issue a Conversion Shares Offer Notice within 10 business days following the Conversion Date notifying the securityholders of our election and (iv) that the Securities will remain in existence for the sole purpose of evidencing the right of the securityholders to receive Conversion Shares or the Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities), and that the Securities may continue to be transferable until the Suspension Date, which will be specified in the Conversion Shares Offer Notice. The date on which the Automatic Conversion Notice is dispatched by us to DTC (or, if the Securities are held in definitive form, to the trustee) will be the date on which such notice is deemed to have been given.

The Automatic Conversion will occur without delay on the Conversion Date (which will be no later than one month following the date on which it is determined such Capital Adequacy Trigger Event has occurred). Within 10 business days following the Conversion Date, we will deliver a Conversion Shares Offer Notice. The “Conversion Shares Offer Notice” will be a written notice to be delivered by us to the trustee and the paying agent directly and to the securityholders via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities) specifying (i) whether or not we have elected that a Conversion Shares Offer be made and, if so, the Conversion Shares Offer Period, (ii) the Suspension Date and (iii) if we have been unable to appoint a Conversion Shares Depository, such other arrangements for the issuance and/or delivery of the Conversion Shares or the Conversion Shares Offer Consideration, as applicable, to the securityholders. The “Suspension Date” will be the date specified in the Conversion Shares Offer Notice as the date on which DTC will suspend all clearance and settlement of transactions in the Securities in accordance with its rules and procedures, which date will be no later than 38 business days after the delivery of the Conversion Shares Offer Notice to DTC (and, if we elect that a Conversion Shares Offer be made, such date will be at least two business days prior to the end of the relevant Conversion Shares Offer Period).

On the Suspension Date, DTC will block all positions relating to the Securities, which will suspend all clearance and settlement of transactions in the Securities through DTC. As a result, the securityholders will not be able to settle the transfer of any Securities through DTC following the Suspension Date, and any sale or other transfer of the Securities that a securityholder may have initiated prior to the Suspension Date that is scheduled to settle after the Suspension Date will be rejected by DTC and will not be settled through DTC. Moreover, the Securities may cease to be admitted to Euronext Dublin’s Official List and to be traded on the GEM (the exchange-regulated market of Euronext Dublin) after the Suspension Date.

S-68

The procedures described in this section are subject to change to reflect changes in DTC’s practices, and we may make changes to the procedures described in this section to the extent reasonably necessary, in our opinion, to reflect such changes in DTC’s practices.

Settlement Procedure

On the Suspension Date, we will deliver an Automatic Conversion Settlement Request Notice. The “Automatic Conversion Settlement Request Notice” will be the written notice to the trustee and the paying agent directly and to the securityholders via DTC (or, if the Securities are held in definitive form, to the securityholders at their addresses shown on the register for the Securities) (i) requesting that the securityholders complete an Automatic Conversion Settlement Notice and (ii) specifying (a) the Notice Cut-off Date and (b) the Final Cancellation Date.

The securityholders (or the custodian, nominee, broker or other representative thereof) will not receive delivery of the relevant Conversion Shares or the Conversion Shares Offer Consideration, as applicable, unless such securityholders (or the custodian, nominee, broker or other representative thereof) deliver the applicable Automatic Conversion Settlement Notice to the Conversion Shares Depository on or before the Notice Cut-off Date; provided that, if such delivery is made after the end of normal business hours at the specified office of the Conversion Shares Depository, such delivery will be deemed for all purposes to have been made or given on the next following business day.

The “Automatic Conversion Settlement Notice” will be a written notice to be delivered by a securityholder (or custodian, broker, nominee or other representative thereof) to the Conversion Shares Depository (or to the relevant recipient of the Conversion Shares in accordance with the terms of the Securities), with a copy to the trustee and the paying agent, no earlier than the Suspension Date, containing the following information: (i) the name of the securityholder (or custodian, broker, nominee or other representative thereof), (ii) the Tradable Amount held by such securityholder (or custodian, broker, nominee or other representative thereof) on the date of such notice, (iii) the name to be entered in our share register, (iv) the details of the CREST or other clearing system account or, if the Conversion Shares are not a participating security in CREST or another clearing system, the address to which the Conversion Shares (or the pro rata Conversion Shares component, if any) should be delivered, (v) for purposes of receiving any pro rata cash component (if not expected to be delivered through DTC), the necessary details and instructions to deposit such pro rata cash component to a bank account that accepts funds in U.S. dollars and (vi) such other details as may be required by the Conversion Shares Depository. The Automatic Conversion Settlement Notice must be given in accordance with the respective standard procedures of DTC (which may include, without limitation, delivery of the notice to the Conversion Shares Depository by electronic means) and in a respective form acceptable to DTC and the Conversion Shares Depository (or, if the Securities are held in definitive form, the Automatic Conversion Settlement Notice must be delivered to the specified office of the Conversion Shares Depository together with the relevant Securities).

Each Automatic Conversion Settlement Notice will be irrevocable. The Conversion Shares Depository will determine, in its sole and absolute discretion, whether any Automatic Conversion Settlement Notice has been properly completed and delivered, and such determination will be conclusive and binding on the relevant securityholder. If any securityholder fails to properly complete and deliver an Automatic Conversion Settlement Notice and the relevant Securities, if applicable, the Conversion Shares Depository will be entitled to treat such Automatic Conversion Settlement Notice as null and void.

Subject to satisfaction of the requirements and limitations set forth in the Indenture and provided that the Automatic Conversion Settlement Notice and the relevant Securities, if applicable, are delivered, the Conversion Shares Depository will deliver the relevant Conversion Shares or Conversion Shares Offer Consideration, as applicable, on the applicable Settlement Date, to the securityholders (or custodian, nominee, broker or other representative thereof) having completed the relevant Automatic Conversion Settlement Notice and in accordance with the instructions given in such Automatic Conversion Settlement Notice.

S-69

If any securityholder (or custodian, nominee, broker or other representative thereof) fails to deliver an Automatic Conversion Settlement Notice (and the relevant Securities, if applicable) to the Conversion Shares Depository on or before the Notice Cut-off Date, the Conversion Shares Depository will continue to hold the Conversion Shares or the Conversion Shares Offer Consideration, as applicable, until an Automatic Conversion Settlement Notice (and the relevant Securities, if applicable) is so delivered; provided that the relevant Securities will be cancelled on the Final Cancellation Date, and any securityholder (or custodian, nominee, broker or other representative thereof) delivering an Automatic Conversion Settlement Notice after the Notice Cut-off Date will be required to provide evidence of its entitlement to the relevant Conversion Shares or Conversion Shares Offer Consideration, as applicable, satisfactory to the Conversion Shares Depository, in its sole and absolute discretion, in order to receive delivery of such Conversion Shares or Conversion Shares Offer Consideration, as applicable. We will have no liability to any securityholder for any loss resulting from such securityholder’s failure to receive any Conversion Shares or Conversion Shares Offer Consideration, as applicable, or from any delay in the receipt thereof, in each case as a result of such securityholder (or custodian, nominee, broker or other representative thereof) failing to duly submit an Automatic Conversion Settlement Notice (and the relevant Securities, if applicable) on a timely basis or at all.

Neither we nor any member of the HSBC Group will be liable for any taxes or duties (including, without limitation, any capital, stamp, issue and registration or transfer taxes or duties) arising on conversion or that may arise or be paid as a consequence of the issue and delivery of Conversion Shares following an Automatic Conversion. The securityholders must pay any taxes or duties (including, without limitation, any capital, stamp, issue and registration and/or transfer taxes or duties) arising on conversion in connection with the issue and delivery of Conversion Shares to the Conversion Shares Depository on behalf of such securityholder and such securityholder must pay all, if any, such taxes or duties arising by reference to any disposal or deemed disposal of such securityholder’s Securities or interest therein. Any taxes or duties arising on delivery or transfer of Conversion Shares to a purchaser in any Conversion Shares Offer will be payable by the relevant purchaser of those Conversion Shares.

The Conversion Shares and any pro rata Conversion Shares component will not be available for delivery (i) to, or to a nominee for, Clearstream Luxembourg or Euroclear or any other person providing a clearance service within the meaning of Section 96 of the Finance Act 1986 of the UK 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 UK, in each case at any time prior to the “abolition day” as defined in Section 111(1) of the Finance Act 1990 of the UK, or, if earlier, such other time at which we, in our absolute discretion, determine 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).

Delivery of the Conversion Shares or pro rata Conversion Shares component, as applicable, to the securityholders will be made in accordance with the procedures described in this section, which remain subject to change to reflect changes in DTC’s practices. Moreover, we may make changes to the procedures described in this section to the extent such changes are reasonably necessary, in our opinion, to effect the delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the securityholders.

Agreement with respect to a Capital Adequacy Trigger Event

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will (i) consent to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic Conversion following a Capital Adequacy Trigger Event and (y) the appointment of the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities), the issuance of the Conversion Shares to the Conversion Shares Depository on behalf of the securityholders (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) acknowledge and agree that

S-70

effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of our winding-up or the appointment of an administrator for our administration as described under “—Subordination,” no securityholder will have any rights against us with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on or in respect of such Securities, in each case that is not due and payable, which liabilities will be automatically released, (iii) acknowledge and agree that events in, and related to, clause (i) may occur without any further action on the part of such securityholder (or beneficial owner), the trustee or the paying agent, (iv) authorize, direct and request DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the Automatic Conversion without any further action or direction on the part of such securityholder (or beneficial owner), the trustee or the paying agent and (v) 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.

Agreement with respect to any Conversion Shares Offer

If we elect, in our sole and absolute discretion, that a Conversion Shares Offer be conducted, by its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will: (i) consent to (x) any Conversion Shares Offer and to the Conversion Shares Depository’s using the Conversion Shares to settle any Conversion Shares Offer in accordance with the terms of the Securities, notwithstanding that such Conversion Shares are held by the Conversion Shares Depository on behalf of the securityholders and (y) 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, and (ii) irrevocably agree that (x) we, the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) 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, and (y) neither we, the trustee, the paying agent, the Conversion Shares Depository nor the Conversion Shares Offer Agent, if any, will, to the extent permitted by applicable law, incur any liability to the securityholders in respect of the Conversion Shares Offer (except for the obligations of the Conversion Shares Depository in respect of the securityholders’ entitlement to any Conversion Shares Offer Consideration).

Agreement with Respect to the Exercise of UK Bail-in Power

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge, accept, consent and agree, notwithstanding any other term of the Securities, the Indenture or any other agreements, arrangements or understandings between us and any securityholder, to be bound by (a) the effect of the exercise of any UK bail-in power by the relevant UK resolution authority in relation to any Securities that (without limitation) may include and result in any of the following, or some combination thereof: (i) the reduction of all, or a portion, of the Amounts Due; (ii) the conversion of all, or a portion, of the Amounts Due into our or another person’s ordinary shares, other securities or other obligations (and the issue to, or conferral on, the securityholder of such ordinary shares, other securities or other obligations), including by means of an amendment, modification or variation of the terms of the Securities or the Indenture; (iii) the cancellation of the Securities; and/or (iv) the amendment or alteration of the redemption date of the Securities or amendment of the amount of interest payable on the Securities, or the interest payment dates, including by suspending payment for a temporary period; and (b) the variation of the terms of the Securities or the Indenture, if necessary, to give effect to the exercise of any UK bail-in power by the relevant UK resolution authority. No repayment or payment of Amounts Due will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise. Moreover, each securityholder (which, for these purposes, includes each beneficial owner) will consent to the exercise of any UK bail-in power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to the Securities.

S-71

For these purposes:

For the avoidance of doubt, the potential conversion of the Securities into shares, other securities or other obligations in connection with the exercise of any UK bail-in power by the relevant UK resolution authority is separate and distinct from an Automatic Conversion following a Capital Adequacy Trigger Event.

According to the principles of the Banking Act, we expect that the relevant UK resolution authority would respect creditor hierarchies when exercising its UK bail-in power in respect of the Securities and that the securityholders would be treated pari passu with the claims of holders of all our additional Tier 1 instruments which in each case by law rank, or by their terms are expressed to rank, pari passu with the Securities at that time being subjected to the exercise of the UK bail-in power (or, with claims in respect of ordinary shares, in the event the exercise of such UK bail-in power occurs in the intervening period between a Capital Adequacy Trigger Event and the Conversion Date).

DTC

Notice via DTC

If notice is given by us via DTC in accordance with the terms of the Securities and the Indenture, we will request that DTC, pursuant to the applicable rules and operating procedures of DTC then in effect, transmit such notice to the direct participants of DTC holding the Securities at such time. Moreover, any notice by DTC to participating institutions and by these participants to street name holders of beneficial interests in the Securities will be made according to arrangements among them and may be subject to statutory or regulatory requirements.

UK Bail-in Power

Upon the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities, we will provide a written notice to the securityholders through DTC as soon as practicable regarding such exercise of the UK bail-in power. We will also deliver a copy of such notice to the trustee for information purposes. Any delay or failure by us in delivering the notices referred to in this paragraph to the securityholders or the trustee shall not affect the validity or enforceability of the UK bail-in power.

By purchasing the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will be deemed to have authorized, directed and requested DTC and any direct participant in DTC or

S-72

other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of any UK bail-in power with respect to the Securities as it may be imposed, without any further action or direction on the part of such securityholder, the trustee or the paying agent.

Anti-dilution

Adjustment of Conversion Price and Conversion Shares Offer Price

Upon the occurrence of any of the events described below, the Conversion Price and the Conversion Shares Offer Price (each, a “Price” and, together, the “Prices”) will be adjusted as follows:

A

B

where:

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

A

B

where:

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

S-73

A+B

A+C

where:

Such adjustment will become effective on the Effective Date.

For the purpose of any calculation of the consideration receivable or price pursuant to this paragraph, the following provisions will apply:

S-74

A-B

 A

where:

Such adjustment will become effective on the Effective Date.

Notwithstanding provisions of this section:

S-75

On any adjustment, if a resultant Price has more decimal places than the initial Price, it will be rounded to the same number of decimal places as the initial Price. No adjustment will be made to a Price where such adjustment (rounded down if applicable) would be less than 1% of such Price then in effect. Any adjustment not required to be made, and/or any amount by which a Price has been rounded down, will be carried forward and taken into account in any subsequent adjustment, and such subsequent adjustment will 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.

The Prices will not in any event be reduced to below the nominal value of one of our ordinary shares for the time being. We undertake that we will not take any action, and will procure that no action is taken, that would otherwise result in an adjustment to the Prices to below such nominal value.

If any doubt arises as to whether an adjustment falls to be made to either Price or as to the appropriate adjustment to such Prices, we may at our discretion appoint an Independent Financial Adviser and, following consultation between us and such Independent Financial Adviser, a written opinion of such Independent Financial Adviser in respect thereof will be conclusive and binding on us, the trustee, the paying agent and the securityholders, save in the case of manifest error.

Notice of any adjustments to the Prices will be given by us to the securityholders via DTC (or, if the Securities are held in definitive form, via the trustee) promptly after the determination thereof.

Although the Prices will be adjusted in certain instances (as described above and elsewhere in this prospectus supplement) in an effort to preserve the securityholders’ economic interest in us, adjustments are not required for every corporate or other event that may affect the market price of the Conversion Shares and an Independent Financial Adviser may make modifications as it determines to be appropriate. See “Risk Factors—Risks Relating to the Securities—You do not have anti-dilution protection in all circumstances.”

No Retroactive Adjustments

We will not issue any additional Conversion Shares if the Automatic Conversion occurs after the record date in respect of any consolidation, reclassification or sub-division as described in the first clause (a) of “—Anti- dilution—Adjustment of Conversion Price and Conversion Shares Offer Price,” or after the record date or other due date for the establishment of entitlement for any such issue, distribution, grant or offer (as the case may be) as is described in clauses (b) through (d) of “—Anti-dilution—Adjustment of Conversion Price and Conversion Shares Offer Price,” but before the relevant adjustment to the Prices becomes effective under such clauses.

Qualifying Takeover Event

Within 10 business days following the occurrence of a Takeover Event, we will deliver a Takeover Event Notice. A “Takeover Event Notice” will be a notice to the securityholders notifying them that a Takeover Event has occurred and specifying: (1) the identity of the Acquirer; (2) whether or not the Takeover Event is a Qualifying Takeover Event; (3) in the case of a Qualifying Takeover Event, if determined at such time, the New Conversion Price and the New Conversion Shares Offer Price; and (4) if applicable, the QTE Effective Date.

S-76

A “Takeover Event” means any person or persons acting in concert (as defined in the Takeover Code of the UK Panel on Takeovers and Mergers) that acquires control of us. For these purposes “control” means (a) the acquisition or holding of legal or beneficial ownership of more than 50% of our issued ordinary shares or (b) the right to appoint and/or remove all or the majority of the members of our board of directors, whether obtained directly or indirectly and whether obtained by ownership of share capital, contract or otherwise. A Takeover Event will constitute a “Qualifying Takeover Event” where (i) the Acquirer is an Approved Entity and (ii) the New Conversion Condition is satisfied.

If the Takeover Event is a Qualifying Takeover Event, the Securities will, where the Conversion Date (if any) falls on or after the QTE Effective Date, be converted on such Conversion Date into or exchanged for Approved Entity Shares, mutatis mutandis as provided under “—Automatic Conversion Upon Capital Adequacy Trigger Event,” at a Conversion Price that will be the New Conversion Price. Such conversion shall be effected by our delivery of such number of HSBC Holdings plc ordinary shares as is determined in accordance with the provisions under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares,” to, or to the order of, the Approved Entity. Such delivery shall irrevocably discharge and satisfy all of our obligations under the Securities (but shall be without prejudice to all of the rights, immunities and indemnification of the trustee under the Indenture and to the rights of the trustee and the securityholders against the Approved Entity in connection with its undertaking to deliver Approved Entity Shares as provided in the definition of “New Conversion Condition”). Such delivery shall be in consideration of the Approved Entity irrevocably undertaking, for the benefit of the securityholders, to (i) deliver the Conversion Shares to the Conversion Shares Depository upon a conversion of the Securities and (ii) ensure that, for so long as the Securities are outstanding, its ordinary share capital shall continue to constitute Approved Entity Shares. In addition, we will retain the right to elect in the Conversion Shares Offer Notice that the Conversion Shares Depository make a Conversion Shares Offer at the New Conversion Shares Offer Price.

The New Conversion Price and the New Conversion Shares Offer Price each will be subject to adjustment in the circumstances provided for under “—Anti-dilution—Adjustment of Conversion Price and Conversion Shares Offer Price” (if necessary with such modifications and amendments as an Independent Financial Adviser will determine to be appropriate), and we will give notice to the securityholders of the New Conversion Price and the New Conversion Shares Offer Price and of any such modifications and amendments thereafter.

In the case of a Qualifying Takeover Event we will, to the extent permitted by applicable law and regulation, on or prior to the QTE Effective Date, enter into such agreements and arrangements (including, without limitation, supplemental indentures to the Indenture and amendments and modifications to the terms and conditions of the Securities and the Indenture) as may be required to ensure that, effective upon the QTE Effective Date, the Securities will (following the occurrence of a Capital Adequacy Trigger Event) be convertible into, or exchangeable for, Approved Entity Shares, mutatis mutandis in accordance with, and subject to, the provisions under “—Automatic Conversion Upon Capital Adequacy Trigger Event,” at the New Conversion Price. From and after the QTE Effective Date, we will no longer have any obligation to deliver HSBC Holdings plc ordinary shares or any Approved Entity Shares to the Conversion Shares Depository, which will be the obligation of the Approved Entity pursuant to the terms of such agreements or arrangements with the trustee entered into by the Approved Entity.

For the avoidance of doubt, if for any reason (including, without limitation, because the Acquirer is a Governmental Entity), a Takeover Event fails to be Qualifying Takeover Event, there will not be any automatic adjustment to the terms of the Securities, whether in the manner provided in respect of Qualifying Takeover Events, or at all.

Subordination

The Securities will constitute our direct, unsecured and subordinated obligations, ranking equally without any preference among themselves. The rights and claims of the securityholders in respect of, or arising from, the

S-77

Securities will be subordinated to the claims of Senior Creditors. For the avoidance of doubt, as of the Issue Date, the 2030 Securities and the 2034 Securities will rank pari passu with one another (and therefore the 2030 Securities and the 2034 Securities will constitute Parity Securities with respect to the other series).

If (i) an order is made, or an effective resolution is passed, for our winding-up (except in any such case for a solvent winding-up solely for the purpose of our merger, reconstruction or amalgamation, the terms of which reorganization, reconstruction or amalgamation (x) have previously been approved in writing by a majority of the securityholders and (y) do not provide that the Securities will thereby become redeemable or repayable in accordance with the terms of the Securities); or (ii) following the appointment of an administrator for our administration, the administrator declares, or gives notice that it intends to declare and distribute, a dividend, then

Furthermore, other than in the event of our winding-up or administration, as described in this section, or with respect to the payment of the pro rata cash component, as described under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Conversion Shares Offer,” payments in respect of, or arising from, the Securities will be conditional (x) upon our being solvent at the time of payment by us, and (y) in that no sum in respect of or arising from the Securities may fall due and be paid except to the extent that we could make such payment and still be solvent immediately thereafter (such condition, the “Solvency Condition”). For purposes of determining whether the Solvency Condition is met, we will be considered to be solvent at a particular point in time if (x) we are able to pay our debts owed to Senior Creditors as they fall due and (y) the Balance Sheet Condition has been met.

A certificate by our auditors as to whether or not the Solvency Condition is met, on the basis of the information provided to our auditors by us, will, in the absence of manifest error, be treated by us, the trustee, the securityholders and all other interested parties as correct and sufficient evidence thereof.

“Senior Creditors” means our creditors (i) who are unsubordinated creditors; (ii) whose claims are, or are expressed to be, subordinated to the claims of our unsubordinated creditors but not further or otherwise; or (iii) whose claims are, or are expressed to be, junior to the claims of our other creditors, whether subordinated or unsubordinated, other than those whose claims rank, or are expressed to rank, pari passu with, or junior to, the

S-78

claims of the securityholders in a winding-up occurring prior to a Capital Adequacy Trigger Event. For the avoidance of doubt, holders of any of our existing or future Tier 2 capital instruments will be Senior Creditors.

The “Balance Sheet Condition” will be satisfied in relation to us if the value of our assets is at least equal to the value of our liabilities. For these purposes (i) “assets” mean our unconsolidated gross assets as shown in our most recent published audited balance sheet, as adjusted for subsequent events in such manner as our auditors may determine and (ii) “liabilities” means our unconsolidated gross liabilities, as shown in our most recent published audited balance sheet, as adjusted for subsequent events in such manner as our auditors may determine and for these purposes excluding (without double counting) any indebtedness that will not constitute 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 we may be organized) in determining whether we are “unable to pay [our] debts” under Section 123(2) of the UK Insolvency Act 1986 or any amendment or re-enactment thereof or in accordance with the corresponding provisions of the applicable laws of such other jurisdiction in which we may be organized.

The subordination provisions of the Indenture, and to which the Securities are subject, will be governed by, and construed in accordance with, the laws of England and Wales.

Modification and Waiver

In addition to our and the trustee’s rights to modify and amend the Indenture described in the accompanying prospectus under “Description of Contingent Convertible Securities—Modification and Waiver,” modifications of and amendments to the terms of the Indenture or the Securities may be made by us and the trustee, without the further consent of the securityholders, to the extent necessary to give effect to the exercise by the relevant UK resolution authority of the UK bail-in power. Moreover, we will agree not to amend the consent of the securityholders to the exercise of the UK bail-in power (see “—Agreement with Respect to the Exercise of UK Bail-in Power”) without the prior consent of the Relevant Regulator.

Defaults and Remedies

For purposes of the Securities, the following discussion replaces in its entirety the discussion set forth in “Description of Contingent Convertible Securities—Contingent Convertible Events of Default” and “Description of Contingent Convertible Securities—Waiver of Contingent Convertible Events of Default and Defaults” in the accompanying prospectus.

Winding-up Event

If a Winding-up Event occurs before the occurrence of a Capital Adequacy Trigger Event, the principal amount of the Securities will become immediately due and payable, without the need for any further action on the part of the trustee, the securityholders or any other person.

A “Winding-up Event” will result if (x) 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 calendar days of the making of such order, (y) our ordinary shareholders adopt an effective resolution for our winding-up (other than, in the case of either (x) or (y) above, under or in connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (z) following the appointment of an administrator, the administrator gives notice that it intends to declare and distribute a dividend.

Non-payment Event

If we fail to pay any amount that has become due and payable under the Securities, the paying agent will notify the trustee and, if such failure continues for 14 calendar days, the trustee may provide a written notice of

S-79

such failure to us. If within a period of 14 calendar 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 to have been cancelled (in each case, in whole or in part) as described under “—Interest— Interest Cancellation” (and no Non-payment Event will occur or be deemed to have occurred as a result of such cancellation or deemed cancellation (in each case, in whole or in part)).

Limited Remedies for Breach of Obligations (Other than Non-payment)

In addition to the remedies for a Non-payment Event, the trustee may without further notice institute such proceedings against us as it may deem fit to enforce any term, obligation or condition binding upon us under the Securities or the Indenture (other than any of our payment obligations under, or arising from, the Securities or the Indenture, including payment of any principal or interest, including Additional Amounts) (such obligation, a “Performance Obligation”); provided the sole and exclusive remedy that the trustee (acting on behalf of the securityholders) and/or the securityholders may seek under the Securities and the Indenture is specific performance under the laws of the State of New York; provided further that to the extent any judgment or other award given in such proceedings requires the payment of money by us, whether by way of damages or otherwise (a “Monetary Judgment”), the trustee (acting on behalf of the securityholders) and/or the securityholders may not enforce, and will not be entitled to enforce, or otherwise claim such Monetary Judgment against us, except by proving such Monetary Judgment in our winding-up or administration. For the avoidance of doubt, any breach by us of any Performance Obligation will not confer upon the trustee (acting on behalf of the securityholders) and/or the securityholders any claim other than specific performance and we will not be obliged to pay any sum or sums, in cash or otherwise (including damages), as a consequence of the institution of any such proceedings, except where a securityholder proves any Monetary Judgment in our winding-up or administration.

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge and agree that (i) the sole and exclusive remedy that such securityholder (or beneficial owner) and/or the trustee (acting on its behalf) may seek under the Securities and the Indenture for a breach by us of a Performance Obligation is specific performance under the laws of the State of New York, (ii) such securityholder (or beneficial owner) will not (and waives any right to) seek, and will not (and waives any right to) direct the trustee (acting on its behalf) to seek, any other remedy against us in respect of any breach by us of a Performance Obligation, (iii) such securityholder (or beneficial owner) will not (and waives any right to) enforce, and will not be entitled to enforce (and waives any such entitlement), or otherwise claim (and waives any other right to claim) a Monetary Judgment against us, except by proving such Monetary Judgment in our winding-up or administration and (iv) to the extent permitted by the Trust Indenture Act, such securityholder (or beneficial owner) will waive any and all claims, in law and/or in equity, against the trustee for, and agree not to initiate a suit, against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in connection with such securityholder’s (or beneficial owner’s) right to enforce a Performance Obligation in accordance with the terms of the Indenture.

No Other Remedies

Other than the limited remedies specified in this section “—Defaults and Remedies,” no remedy against us will be available to the trustee (acting on behalf of the securityholders) or to the securityholders (which, for these purposes, includes each beneficial owner), whether for the recovery of amounts owing in respect of such 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 that notwithstanding the limitations on remedies specified in this section “—Defaults and Remedies,” (x) 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 securityholders under the provisions of the Indenture, and (y) nothing will impair the right of a securityholder

S-80

under the Trust Indenture Act, absent such securityholder’s consent, to sue for any payment due and unpaid with respect to the Securities; provided further that, in the case of (x) and (y), 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, will be subject to the subordination provisions described under “—Subordination.”

Defaults

A “default” will occur (i) upon the occurrence of a Winding-up Event that occurs before the Conversion Date, (ii) upon the occurrence of a Non-payment Event or (iii) upon a breach by us of a Performance Obligation.

For purposes of the accompanying prospectus, “contingent convertible event of default” will mean “default” as defined in this prospectus supplement.

Under the terms of the Indenture and the Securities, neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or cancellation, in part or in full, of the Amounts Due, the conversion of the Securities into another security or obligation of us or another person, as a result of the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities, nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities, will be a contingent convertible event of default or a default. As a result, the securityholders will not have the right to request that the trustee declare an acceleration solely due to the occurrence of a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or cancellation, in part or in full, of the Amounts Due, the conversion of the Securities into another security or obligation of us or another person, as a result of the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities, or the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities.

Waiver of Past Default

Holders of not less than a majority of the aggregate principal amount of the Securities then outstanding may on behalf of all securityholders waive any past default that results from a breach by us of a Performance Obligation; provided that (i) a default in respect of a Performance Obligation, the modification or amendment of which would require the consent of each securityholder affected by it or (ii) any past default that results from a Winding-up Event or a Non-payment Event, in either case, will require the waiver of each securityholder affected by such default.

Upon the occurrence of any waiver of a default described in the immediately preceding paragraph, such default will cease to exist, and any default with respect to any series of Securities arising therefrom will be deemed to have been cured and not to have occurred for any purpose under the Indenture; provided that no such waiver will extend to any subsequent or other default or impair any right consequent thereon.

Trustee

Trustee; Direction of the Trustee

The Bank of New York Mellon, London Branch, is the trustee under the Indenture. See “—Trustee— Trustee’s Duties” and “Description of Contingent Convertible Securities—Trustee’s Duties” in the accompanying prospectus for a description of the trustee’s procedures and remedies available in connection with a default.

The trustee makes no representations, and will not be liable with respect to, the information set forth in this prospectus supplement.

UK Bail-in Power

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner), to the extent permitted by the Trust Indenture Act, will waive any and all claims, in law and/or in equity,

S-81

against the trustee for, agree not to initiate a suit against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of any UK bail-in power by the relevant UK resolution authority with respect to the Securities.

Additionally, by its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge and agree that, upon the exercise of any UK bail-in power by the relevant UK resolution authority,

Notwithstanding the foregoing, if, following the completion of the exercise of the UK bail-in power by the relevant UK resolution authority, the Securities remain outstanding (for example, if the exercise of the UK bail-in power results in only a partial write-down of the principal of the Securities), then the trustee’s duties under the Indenture will remain applicable with respect to the Securities following such completion to the extent that we and the trustee will agree pursuant to another supplemental indenture or an amendment to the Indenture; provided, however, that notwithstanding the exercise of the UK bail-in power by the relevant UK authority, there will at all times be a trustee for the Securities in accordance with the Indenture, and the resignation and/or removal of the trustee and the appointment of a successor trustee will continue to be governed by the Indenture, including to the extent no additional supplemental indenture or amendment to the Indenture is agreed upon in the event the Securities remain outstanding following the completion of the exercise of the UK bail-in power.

Our obligations to indemnify the trustee in accordance with Section 6.07 of the Indenture will survive any Automatic Conversion under the Indenture.

The exercise of the UK bail-in power by the relevant UK authority with respect to the Securities will not constitute a Winding-up Event or a Non-payment Event.

Capital Adequacy Trigger Event

Once we have delivered an Automatic Conversion Notice following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) subject to the right of the securityholders in the event of our failure to issue and deliver any Conversion Shares to the Conversion Shares Depository on the Conversion Date described under “—Automatic Conversion Upon Capital Adequacy Trigger Event—Automatic Conversion,” the securityholders will have no rights whatsoever under the Indenture or the Securities to instruct the trustee or the paying agent to take any action whatsoever and (ii) as of the date of the Automatic Conversion Notice, except for any indemnity and/or security provided by any securityholder in such direction or related to such direction, any direction previously given to the trustee by any securityholder will cease automatically and will be null and void and of no further effect; except in each case of (i) and (ii), with respect to any rights of the securityholders with respect to any payments under the Securities that were unconditionally due and payable prior to the date of the Automatic Conversion Notice or unless the trustee or the paying agent is instructed in writing by us to act otherwise.

Neither the trustee nor the paying agent will be liable with respect to (i) the calculation or accuracy of the non-transitional CET1 Ratio in connection with the occurrence of a Capital Adequacy Trigger Event and the timing of such Capital Adequacy Trigger Event, (ii) our failure to post or deliver the underlying non-transitional CET1 Ratio calculations of a Capital Adequacy Trigger Event to DTC or the securityholders or (iii) any aspect of our decision to deliver an Automatic Conversion Notice or the related Automatic Conversion.

S-82

Trustee’s Duties

For purposes of the Securities, the following discussion replaces in its entirety the first paragraph in “Description of Contingent Convertible Securities—Trustee’s Duties” in the accompanying prospectus.

In the case of a default, the trustee will 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. Subject to the provisions of the Indenture relating to the duties of the trustee, in case a default occurs and is continuing with respect to the Securities, the trustee will be under no obligation to any securityholder to exercise any of its rights or powers under the Indenture at the request of any securityholder unless such securityholder will have offered to the trustee indemnity satisfactory to the trustee.

Subject to such provisions for the indemnification of the trustee, and subject to certain exceptions, the holder or holders of a majority in aggregate principal amount of the Securities then outstanding will 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 the Securities. However, the trustee may refuse to follow any direction that is in conflict with any rule of law or the Indenture or is unjustly prejudicial to any securityholder not taking part in the direction. The trustee may take any other action that it deems proper which is not inconsistent with that direction. See also “—Defaults and Remedies—No Other Remedies.”

By its acquisition of the Securities, each securityholder (which, for these purposes, includes each beneficial owner) will acknowledge and agree that neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or cancellation, in part or in full, of the Amounts Due, the conversion thereof into another security or obligation of us or another person, as a result of the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities, nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the Securities will 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.

Payments Subject to Fiscal Laws

All payments are subject in all cases to any applicable fiscal or other laws, regulations and directives in any jurisdiction, but without prejudice to the “Description of Contingent Capital Securities—Additional Amounts” provisions in the accompanying prospectus. For the purposes of the preceding sentence, the phrase “fiscal or other laws, regulations and directives” will include any obligation on us to withhold or deduct from a payment pursuant to an agreement described in Section 1471(b) of the Code, or otherwise imposed pursuant to FATCA.

Paying Agent

Payments of principal of and interest, if any, on the Securities will be made in U.S. dollars and such payments on Securities represented by a global security will be made through one or more paying agents to DTC or its nominee. Initially, the paying agent will be HSBC Bank USA, National Association. We may change the paying agent without prior notice to the securityholders, and in such an event we may act as paying agent. Payments of principal of, and interest on, the Securities represented by a global security will be made by wire transfer of immediately available funds.

Calculation Agent

The calculation agent is HSBC Bank USA, National Association, or its successor appointed by us, pursuant to a calculation agent agreement expected to be entered into on the Issue Date.

Subsequent Holders’ Agreement

Any securityholder (which, for these purposes, includes each beneficial owner of the Securities) that acquires the Securities in the secondary market and any successors, assigns, heirs, executors, administrators,

S-83

trustees in bankruptcy and legal representatives of any securityholder or beneficial owner of the Securities will be deemed to acknowledge, accept, agree to be bound by and consent to the same provisions specified herein to the same extent as the securityholders or beneficial owners 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 related to the UK bail-in power and related to a Capital Adequacy Trigger Event.

Governing Law and Jurisdiction

The Indenture and the Securities will be governed by, and construed in accordance with, the laws of the State of New York, except that the subordination provisions of the Indenture and of the Securities (see “—Subordination”) and the waiver of set-off provisions of the Indenture and the Securities (see “Description of Contingent Capital Securities—No Right of Set-Off by Holders” in the accompanying prospectus) will be governed by, and construed in accordance with, the laws of England and Wales. Any legal proceedings arising out of, or based upon, the Indenture or the Securities may be instituted in any state or federal court in New York City, United States.

TAXATION

General

Holders of the Securities should be aware that the tax legislation of any jurisdiction where a holder is resident or otherwise subject to taxation (as well as the jurisdictions discussed below) may have an impact on the tax consequences of an investment in the Securities including in respect of any income received from the Securities.

United States Federal Income Tax Considerations

This section discusses material U.S. federal income tax considerations of an investment in the Securities and the Conversion Shares by certain beneficial holders thereof. Except as otherwise noted below, this summary replaces, and should be read to supersede, the discussion of tax matters discussed in the section entitled “Taxation—U.S. Taxation” in the accompanying prospectus. This section does not purport to be a comprehensive description of all of the tax considerations that may be relevant to any particular investor. We have assumed that you are familiar with the tax rules applicable to investments in securities generally and with any special rules to which you may be subject.

The following is a summary of material U.S. federal income tax considerations that may be relevant to a U.S. Holder (as defined below) of a Security or Conversion Shares, and certain considerations (described below in “—Information Reporting and Backup Withholding” and “—FATCA”) relevant to both a U.S. Holder and a Non-U.S. Holder (as defined below) of a Security.

This summary deals only with holders that purchase Securities as part of an initial offering and hold Securities or Conversion Shares as capital assets for U.S. federal income tax purposes. It does not address tax considerations applicable to investors that may be subject to special tax rules, including banks or other financial institutions, tax-exempt entities, insurance companies, regulated investment companies, common trust funds, entities that are treated for U.S. federal income tax purposes as partnerships or other pass-through entities, dealers in securities or currencies, traders in securities that elect mark-to-market treatment, persons that will hold Securities or Conversion Shares as part of an integrated investment, including a straddle, a synthetic security or hedge or a conversion transaction, persons that own or are deemed to own 10% or more of our stock, measured by voting power or value, or U.S. Holders that have a functional currency other than the U.S. dollar. In addition, this summary does not address consequences arising under state, local, foreign tax laws, any alternative minimum tax or any aspects of the Medicare contribution tax on net investment income. Furthermore, this summary does not address the tax treatment of the Securities following any exercise of the UK bail-in power by the relevant UK resolution authority. Finally, this summary does not address the tax treatment of Conversion Shares that may be denominated in or provide for payments in a currency other than the U.S. dollar.

The summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, in each case as of the date hereof, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly with retroactive effect. Persons considering the purchase of Securities should consult their own tax advisers in determining the tax consequences to them of the purchase, ownership and disposition of Securities or Conversion Shares, including the application to their particular situation of the U.S. federal income tax considerations discussed below, as well as the application of U.S. state, local, foreign or other tax laws.

As used in this prospectus supplement, the term “U.S. Holder” means:

S-96

As used in this summary, the term “Non-U.S. Holder” means a holder that is not a U.S. Holder and is not an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

U.S. Tax Status of the Securities; Distributions on the Securities and the Conversion Shares

The Securities will be treated as equity of HSBC Holdings for U.S. federal income tax purposes. Interest payments with respect to the Securities, and distributions with respect to the Conversion Shares, will be treated as dividends for U.S. federal income tax purposes to the extent of HSBC Holdings’ current or accumulated earnings and profits as determined for U.S. federal income tax purposes, 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 generally be treated as capital gain, the tax treatment of which is discussed below under “—Sale, Exchange, Redemption or Other Disposition of the Securities and Conversion Shares.” Because HSBC Holdings 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.

Dividends received by certain non-corporate U.S. Holders will be subject to taxation at preferential rates if the dividends are “qualified dividends.” Subject to certain exceptions for short-term and hedged positions, interest received with respect to the Securities and distributions with respect to the Conversion Shares will be qualified dividends if (i) either (A) HSBC Holdings is eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service (the “IRS”) has approved for purposes of the qualified dividend rules, or (B) the Securities or Conversion Shares are readily tradable on an established securities market in the United States, and (ii) HSBC Holdings was not, in the year prior to the year in which the interest payment was made, and is not, in the year in which the interest payment is made, a passive foreign investment company (“PFIC”). HSBC Holdings expects to be eligible for the benefits of the comprehensive income tax treaty between the United States and the UK (which has been approved by the IRS for the purposes of the qualified dividend rules). Based on the HSBC Holdings’ audited financial statements and relevant market data, HSBC Holdings believes that it was not a PFIC for U.S. federal income tax purposes with respect to its 2023 taxable year. In addition, based on its audited financial statements and its current expectations regarding the value and nature of its assets, the sources and nature of its income, and relevant market data, HSBC Holdings does not anticipate becoming a PFIC for its 2024 taxable year, or in the foreseeable future. Accordingly, subject to certain exceptions for short-term and hedged positions, HSBC Holdings expects that the dividends received by non-corporate U.S. Holders will generally be subject to taxation at preferential rates. If, contrary to the conclusion above, the issuer was a PFIC for U.S. federal income tax purposes, such treatment generally would result in adverse tax consequences to U.S. Holders. U.S. Holders should consult their tax advisers regarding the application of the PFIC rules to an investment in Securities or Conversion Shares.

Interest payments on the Securities and distributions with respect to the Conversion Shares generally will constitute foreign-source, “passive” category income for foreign tax credit purposes and will not be eligible for the dividends-received deduction available to domestic corporations. The amount of a payment on the Securities or the Conversion Shares will include amounts, if any, withheld in respect of UK taxes. See “—UK Taxation.” Subject to certain limitations, including new requirements adopted by the IRS in regulations promulgated in December 2021, UK taxes withheld from payments on the Securities or the Conversion Shares to a U.S. Holder generally will give rise to a foreign tax credit or deduction for U.S. federal income tax purposes. The foreign tax credit rules are complex. U.S. Holders should consult their tax advisers regarding the creditability or deductibility of foreign taxes in their particular circumstances.

S-97

Automatic Conversion into Conversion Shares

The conversion of Securities into Conversion Shares pursuant to an Automatic Conversion will not be treated as a taxable exchange for U.S. Holders. A U.S. Holder’s tax basis in Conversion Shares received pursuant to an Automatic Conversion 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 the Automatic Conversion. A U.S. Holder’s tax basis in a Security generally will equal the cost of that Security to such holder.

Conversion of 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, a U.S. Holder will recognize gain or loss equal to the difference between the fair market value of the Approved Entity Shares received upon the conversion or exchange and the holder’s 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 into Conversion Shares,” with respect to the receipt of Conversion Shares following an Automatic Conversion.

Assumption of Obligations

The U.S. federal income tax treatment of an assumption of our obligations under the Securities by either a subsidiary or a holding company of ours (described in “Description of Contingent Convertible Securities— Assumption of Obligations” in the accompanying prospectus) is uncertain. Such assumption might be deemed by the IRS to be a taxable exchange of the Securities for new contingent convertible securities for U.S. federal income tax purposes if the new contingent convertible securities are treated as differing materially in kind or extent from the Securities, in which case a U.S. Holder should recognize gain, if any. Deductibility of loss, if any, may be limited pursuant to, among other things, the wash sale rules. U.S. Holders should consult their own tax advisers with respect to the tax consequences of such an assignment.

Sale, Exchange, Redemption or Other Disposition of the Securities and Conversion Shares

Upon any sale, exchange, redemption or other disposition of Securities or Conversion Shares (other than a conversion of the Securities into Conversion Shares, as discussed above), including the sale of Conversion Shares pursuant to the Conversion Shares Offer, a U.S. Holder generally will recognize gain or loss equal to the difference between (1) the amount realized on the disposition and (2) the U.S. Holder’s adjusted tax basis in such Securities or Conversion Shares, provided that, in the case of a redemption, the U.S. Holder does not own, and is not deemed to own, any ordinary shares of HSBC Holdings or securities of HSBC Holdings treated as equity for U.S. federal income tax purposes at such time. Additionally, you will generally recognize a capital loss on the complete cancellation of the Securities pursuant to the UK bail-in power in an amount equal to your tax basis in the Securities.

Such gain or loss will generally be U.S.-source capital gain or loss and will generally be long-term gain or loss if the U.S. Holder has held the Securities or Conversion Shares for more than one year. Net long-term capital gain recognized by certain non-corporate U.S. Holders will generally be subject to taxation at preferential rates. Additionally, even if the Securities or Conversion Shares are held for less than one year, loss recognized on a sale, exchange, redemption or other disposition of the Securities or Conversion Shares will be long-term capital loss to the extent of any payments of interest received by the U.S. Holder which constitute qualified dividend income and are considered “extraordinary dividends.” Payments of interest on the Securities or Conversion Shares may be considered extraordinary dividends if the U.S. Holder purchased the Securities or Conversion Shares at a premium to the price listed on the cover hereof. The deductibility of capital losses is subject to limitations. U.S. Holders should consult their tax advisers regarding the applicability of extraordinary dividend treatment in their particular circumstances.

S-98

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 UK bail-in power. U.S. Holders should consult their own tax advisers regarding the tax consequences of such situations 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 and the Conversion Shares Offer Price

The Conversion Price and the Conversion Shares Offer Price are subject to adjustment under certain circumstances. A U.S. Holder of the Securities may be treated 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. 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 will be treated as having received a distribution even though they have not received any cash or property. For example, increases in the Conversion Price and the Conversion Shares Offer 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 will be includable in such U.S. Holder’s income at its fair market value at the time of the distribution in a manner described above under “—U.S. Tax Status of the Securities; Distributions on the Securities and the Conversion Shares.” Adjustments to the Conversion Price and the Conversion Shares Offer 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.

Foreign Financial Asset Reporting

Certain U.S. Holders that own “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 are generally required to file an information statement along with their tax returns, currently on Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer (which would include the Securities and the Conversion Shares) that are not held in accounts maintained by financial institutions. Higher reporting thresholds apply to certain individuals living abroad and to certain married individuals. Regulations extend this reporting requirement to certain entities that are treated as formed or availed of to hold direct or indirect interests in specified foreign financial assets based on certain objective criteria. U.S. Holders that fail to report the required information could be subject to substantial penalties. In addition, the statute of limitations for assessment of tax would be suspended, in whole or part. Prospective investors should consult their own tax advisors concerning the application of these rules to their investment in the Securities and the Conversion Shares, including the application of the rules to their particular circumstances.

Information Reporting and Backup Withholding

Payments in respect of the Securities and the Conversion Shares generally may be subject to the information reporting requirements of the Code and may be subject to backup withholding unless the U.S. Holder (1) establishes that it is a corporation (other than an S corporation) or other exempt holder or (2) provides a correct taxpayer identification number, certifies that no loss of exemption from backup withholding has occurred and otherwise complies with the applicable requirements of the backup withholding rules. The amount of any backup withholding from a payment to a holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle such U.S. Holder to a refund, provided that certain required information is furnished to the IRS in a timely manner. A Non-U.S. Holder may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and backup withholding.

S-99

FATCA

Pursuant to FATCA, you may be required to provide information and tax documentation regarding your tax identity as well as that of your direct and indirect owners, which may be reported to HM Revenue & Customs (“HMRC”), and ultimately, the IRS. It is also possible that “foreign passthru payments,” as defined under FATCA, on any of the Securities or Conversion Shares may be subject to a withholding tax of 30%. Regulations implementing this rule have not yet been adopted or proposed and the IRS has indicated that withholding would only apply for payments made more than two years after the date on which final U.S. Treasury regulations defining the term “foreign passthru payment” are published in the U.S. Federal Register.

FATCA is particularly complex. You should consult your own tax advisor to obtain a more detailed explanation of FATCA and to learn how this legislation might affect you in your particular circumstance.

UK Taxation

The following disclosure supplements and should be read in addition to the disclosure set forth in the accompanying prospectus, beginning on page 50, under “Taxation.”

Stamp Duty and Stamp Duty Reserve Tax

The Finance Act 2019 introduced a new regime for hybrid capital instruments (the “HCI rules”). Since the HCI rules exempt the transfer of a hybrid capital instrument from all stamp duties, and since securities the transfer of which is exempt from all stamp duties are not chargeable securities for stamp duty reserve tax purposes, no liability to UK 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:

We will make a valid hybrid capital instrument election in respect of the Securities within the required timeframe pursuant to section 475C of the 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. It is consequently expected that the HCI rules should apply to the Securities such that they would benefit from the exemption from all stamp duties on transfer.

S-100

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

No liability to UK stamp duty or stamp duty reserve tax will arise for a securityholder on the release of our obligations under the Securities on Automatic Conversion.

No liability to UK stamp duty or stamp duty reserve tax will arise for a securityholder on the issuance of new ordinary shares in HSBC Holdings plc by us to the securityholder under an Automatic Conversion.

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

The above description of the UK stamp duty and stamp duty reserve tax position does not deal with the issue, transfer or agreement to transfer of any Approved Entity Shares.

S-101

CERTAIN ERISA CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), imposes certain requirements on employee benefit plans subject to Title I of ERISA and on entities or accounts that are deemed to hold the assets of such plans (“ERISA Plans”), and on those persons who are fiduciaries with respect to ERISA Plans. Investments by ERISA Plans are subject to ERISA’s general fiduciary requirements, including, but not limited to, the requirement of investment prudence and diversification and the requirement that an ERISA Plan’s investments be made in accordance with the documents governing the ERISA Plan.

Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of an ERISA Plan as well as those plans that are not subject to ERISA but which are subject to Section 4975 of the Code, such as individual retirement accounts, and entities or accounts deemed to hold the assets of such plans (together with ERISA Plans, “Plans”) and certain persons (referred to as “parties in interest” under ERISA or “disqualified persons” under the Code) having certain relationships to such Plans, unless a statutory or administrative exemption is applicable to the transaction. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the Plan that is engaged in such a non-exempt prohibited transaction may be, among other things, subject to penalties under ERISA and the Code.

The fiduciary of a Plan that proposes to purchase and hold any Securities (or any interest therein) should consider, among other things, whether such purchase and holding may involve (i) the direct or indirect extension of credit to a party in interest or a disqualified person, (ii) the sale or exchange of any property between a Plan and a party in interest or a disqualified person, (iii) the transfer to, or use by or for the benefit of, a party in interest or disqualified person, of any Plan assets, or (iv) any prohibited conflicts of interest. Such parties in interest or disqualified persons could include, without limitation, HSBC, the underwriters, the agents or any of their respective affiliates (“Transaction Parties”).

Depending on the satisfaction of certain conditions which may include the identity of the Plan fiduciary making the decision to acquire or hold the Securities (or any interest therein) on behalf of a Plan, exemptions from the prohibited transaction provisions of ERISA and Section 4975 of the Code could potentially include, without limitation, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code (relating to transactions with certain service providers) or Prohibited Transaction Class Exemption (“PTCE”) 84-14 (relating to transactions effected by a “qualified professional asset manager”), PTCE 90-1 (relating to investments by insurance company pooled separate accounts), PTCE 91-38 (relating to investments by bank collective investment funds), PTCE 95-60 (relating to investments by insurance company general accounts) or PTCE 96-23 (relating to transactions directed by an in-house asset manager) (collectively, the “Class Exemptions”). However, there can be no assurance that any of these Class Exemptions or any other exemption will be available with respect to any particular acquisition or other transaction involving the Securities.

Any Plan fiduciary that proposes to cause a Plan to purchase the Securities should consult with its counsel regarding the applicability of the fiduciary responsibility and prohibited transaction provisions of ERISA and Section 4975 of the Code to such an investment, and to confirm that its purchase, holding and disposition of the Securities will not constitute or result in a non-exempt prohibited transaction or any other violation of an applicable requirement of ERISA or the Code. None of the Transaction Parties has provided, and none of them will provide, any impartial investment recommendation or investment advice, and are not giving any advice in a fiduciary capacity, in connection with any Plan’s investment in the Securities.

Non-U.S. plans, governmental plans (as defined in Section 3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA), while not subject to the fiduciary responsibility provisions of ERISA or the prohibited transaction provisions of ERISA and Section 4975 of the Code, may nevertheless be subject to other federal, state, local or non-U.S. laws or regulations that are substantially similar to the foregoing provisions of ERISA and the Code (“Similar Law”). Fiduciaries of any such plans subject to Similar Law (“Non-ERISA

S-102

Plans”) should consult with their counsel before purchasing the Securities to determine the need for, if necessary, and the availability of, any exemptive relief under any Similar Law.

Through its purchase or other acquisition and holding of the Securities (including any interest in a Security), each purchaser or other acquirer of the Securities (and each Plan fiduciary and each fiduciary of a Non-ERISA Plan directing or advising a Plan or Non-ERISA Plan to purchase or otherwise acquire and hold the Securities) will be deemed to have represented and agreed that either: (A) no assets of a Plan or Non-ERISA Plan have been used to acquire or will be used to hold such Securities or an interest therein or (B) the purchase, other acquisition, holding and disposition of the Securities or any interest therein do not and will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or violation of Similar Law.

Each Plan fiduciary (and each fiduciary for a Non-ERISA Plan) should consult with its legal adviser concerning the potential consequences to the plan under ERISA, Section 4975 of the Code or Similar Law of an investment in the Securities.

S-103

UNDERWRITING (CONFLICTS OF INTEREST)

The underwriters named below have severally agreed, subject to the terms and conditions of the underwriting agreement with us, as amended, effective as of the date of this prospectus supplement, to purchase the principal amount of Securities set forth below opposite their respective names.

S-104

The underwriters propose to offer the Securities in part directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement and in part to certain securities dealers at such price less a concession not in excess of 0.600% of the principal amount of the 2030 Securities or 0.600% of the principal amount of the 2034 Securities, as applicable. The underwriters may allow, and such dealers may reallow, a concession not to exceed 0.360% of the principal amount of the 2030 Securities or 0.360% of the principal amount of the 2034 Securities, as applicable, to certain brokers and dealers. After the initial public offering, the public offering price, concession and discount may be changed. In addition, HSI and/or its affiliates will reimburse us for certain of our offering-related expenses and underwriting discounts and commissions.

S-105

Certain of the underwriters may not be U.S. registered broker-dealers and accordingly will not effect any offers or sales of any Securities in the United States unless it is through one or more U.S. registered broker-dealers as permitted by applicable securities laws and the regulations of FINRA.

The underwriting agreement provides that the obligations of the underwriters to purchase the Securities included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters have agreed to purchase all of the Securities sold pursuant to the underwriting agreement if any of the Securities are sold. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the several underwriters against certain liabilities, including civil liabilities under the Securities Act, or contribute to payments the underwriters may be required to make in respect thereof.

It is expected that the delivery of the Securities will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which is the fifth business day following the date hereof (this settlement cycle being referred to as T+5). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to the trade expressly agree otherwise. Accordingly, purchasers who wish to trade Securities prior to one business day before delivery will be required, by virtue of the fact that the Securities initially will settle in T+5, to specify an alternative settlement cycle at the time of any trade to prevent a failed settlement and should consult their own adviser.

The following are the estimated expenses to be incurred in connection with the issuance and distribution of the Securities:

In connection with the offering made hereby, the underwriters or persons acting on their behalf may purchase and sell the Securities in the open market. These transactions may include over-allotment and stabilizing transactions and purchases to cover short positions created by the underwriters in connection with the offering. Short positions created by the underwriters involve the sale by the underwriters or persons acting on their behalf of a greater number of Securities than they are required to purchase from us. Stabilization transactions consist of certain bids or purchases for the purpose of preventing or retarding a decline in the market price of the Securities. The underwriters may also impose a penalty bid, whereby selling concessions allowed to broker-dealers in respect of the Securities sold in the offering may be reclaimed by the underwriters if such Securities are repurchased by the underwriters or persons acting on their behalf in stabilization or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the Securities, which may be higher than the price that might otherwise prevail in the open market. These activities, if commenced, may be discontinued at any time.

These transactions may be effected on the GEM or otherwise. These activities, if commenced, will be conducted in accordance will all applicable laws and rules.

Any stabilization action may begin on or after the date of adequate public disclosure of the final terms of the offer of the relevant Securities and, if begun, may be ended at any time, but it must end no later than 30 days after the Issue Date, or no later than 60 days after the date of allotment of the relevant Securities, whichever is

S-106

the earlier. Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Securities. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued.

Important Notice to CMIs (including private banks) Pursuant to Paragraph 21 of the Hong Kong SFC Code of Conduct

This notice to CMIs (including private banks) is a summary of certain obligations the SFC Code imposes on CMIs, which require the attention and cooperation of other CMIs (including private banks). Certain CMIs may also be acting as OCs for this offering and are subject to additional requirements under the SFC Code.

Prospective investors who are the directors, employees or major shareholders of the issuer, a CMI or its group companies would be considered under the SFC Code as having an Association with the issuer, the CMI or the relevant group company. CMIs should specifically disclose whether their investor clients have any Association when submitting orders for the Securities. In addition, private banks should take all reasonable steps to identify whether their investor clients may have any Associations with the issuer or any CMI (including its group companies) and inform the underwriters accordingly.

CMIs are informed, unless otherwise notified, that the marketing and investor targeting strategy for this offering includes institutional investors, sovereign wealth funds, pension funds, hedge funds, family offices and high net worth individuals, in each case, subject to the selling restrictions and any MiFID II product governance language or any UK MiFIR product governance language set out elsewhere in this prospectus supplement.

CMIs should ensure that orders placed are bona fide, are not inflated and do not constitute duplicated orders (i.e. two or more corresponding or identical orders placed via two or more CMIs). CMIs should enquire with their investor clients regarding any orders which appear unusual or irregular. CMIs should disclose the identities of all investors when submitting orders for the Securities (except for omnibus orders where underlying investor information may need to be provided to any OCs when submitting orders). Failure to provide underlying investor information for omnibus orders, where required to do so, may result in that order being rejected. CMIs should not place “X-orders” into the order book.

CMIs should segregate and clearly identify their own proprietary orders (and those of their group companies, including private banks as the case may be) in the order book and book messages.

CMIs (including private banks) should not offer any rebates to prospective investors or pass on any rebates provided by the issuer. In addition, CMIs (including private banks) should not enter into arrangements which may result in prospective investors paying different prices for the Securities.

The SFC Code requires that a CMI disclose complete and accurate information in a timely manner on the status of the order book and other relevant information it receives to targeted investors for them to make an informed decision. In order to do this, those underwriters in control of the order book should consider disclosing order book updates to all CMIs.

When placing an order for the Securities, private banks should disclose, at the same time, if such order is placed other than on a “principal” basis (whereby it is deploying its own balance sheet for onward selling to investors). Private banks who do not provide such disclosure are hereby deemed to be placing their order on such a “principal” basis. Otherwise, such order may be considered to be an omnibus order pursuant to the SFC Code. Private banks should be aware that placing an order on a “principal” basis may require the relevant affiliated underwriter(s) (if any) to categorise it as a proprietary order and apply the “proprietary orders” requirements of the SFC Code to such order.

S-107

In relation to omnibus orders, when submitting such orders, CMIs (including private banks) that are subject to the SFC Code should disclose underlying investor information in respect of each order constituting the relevant omnibus order (failure to provide such information may result in that order being rejected). Underlying investor information in relation to omnibus orders should consist of:

Underlying investor information in relation to an omnibus order should be sent to the underwriters who have requested such information.

To the extent information being disclosed by CMIs and investors is personal and/or confidential in nature, CMIs (including private banks) agree and warrant: (A) to take appropriate steps to safeguard the transmission of such information to any OCs; and (B) that they have obtained the necessary consents from the underlying investors to disclose such information to any OCs. By submitting an order and providing such information to any OCs, each CMI (including private banks) further warrants that they and the underlying investors have understood and consented to the collection, disclosure, use and transfer of such information by any OCs and/or any other third parties as may be required by the SFC Code, including to the issuer, relevant regulators and/or any other third parties as may be required by the SFC Code, for the purpose of complying with the SFC Code, during the bookbuilding process for this offering. CMIs that receive such underlying investor information are reminded that such information should be used only for submitting orders in this offering. The underwriters may be asked to demonstrate compliance with their obligations under the SFC Code, and may request other CMIs (including private banks) to provide evidence showing compliance with the obligations above (in particular, that the necessary consents have been obtained). In such event, other CMIs (including private banks) are required to provide the relevant underwriter with such evidence within the timeline requested.

Selling Restrictions

The Securities are offered for sale only in jurisdictions where it is legal to make such offers. The offer and sale of the Securities are subject to the following limitations.

Switzerland

The Securities are not subject to the approval of, or supervision by, the Swiss Financial Market Supervisory Authority (“FINMA”) and investors in the Securities will not benefit from supervision by FINMA. Securities do not constitute participations in a collective investment scheme within the meaning of the Swiss Federal Act on Collective Investment Schemes of 23 June 2006, as amended. Securities are neither issued nor guaranteed by a Swiss financial intermediary. Investors are exposed to the credit risk of the issuer.

The offering of the Securities in Switzerland is exempt from the requirement to prepare and publish a prospectus under the Swiss Financial Services Act (“FinSA”) because the Securities have a minimum denomination of CHF 100,000 (or equivalent in another currency) or more. This prospectus supplement does not constitute a prospectus pursuant to the FinSA, and no such prospectus has been or will be prepared for or in connection with the offering of the Securities.

No key information document according to the FinSA or any equivalent document under the FinSA has been prepared in relation to the Securities and, therefore, the Securities may not be offered or recommended to private clients within the meaning of the FinSA in Switzerland.

S-109

(b) it has not issued or had in its possession for the purposes of issue, and will not issue or have in its possession for the purposes of issue, whether in Hong Kong or elsewhere, any advertisement, invitation or document relating to the Securities, which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to Securities which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” as defined in the SFO and any rules made thereunder.

Singapore

Each underwriter has acknowledged that this prospectus supplement and the accompanying prospectus have not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, each underwriter has represented, warranted and agreed that it has not offered or sold any Securities or caused the Securities to be made the subject of an invitation for subscription or purchase and will not offer or sell any Securities or cause the Securities to be made the subject of an invitation for subscription or purchase, and has not circulated or distributed, nor will it circulate or distribute, this prospectus supplement and the accompanying prospectus or any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the Securities, whether directly or indirectly, to any person in Singapore other than (i) to an institutional investor (as defined in Section 4A of the Securities and Futures Act 2001 of Singapore, as modified or amended from time to time (the “SFA”)) pursuant to Section 274 of the SFA, or (ii) to an accredited investor (as defined in Section 4A of the SFA) pursuant to and in accordance with the conditions specified in Section 275 of the SFA.

Canada

Each underwriter has acknowledged that no prospectus has been filed with any securities commission or similar regulatory authority in Canada in connection with the offer and sale of the Securities, the Securities have not been, and will not be, qualified for sale under the securities laws of Canada or any province or territory thereof and no securities commission or similar regulatory authority in Canada has reviewed or in any way passed upon this prospectus supplement, the accompanying prospectus or the merits of the Securities and any representation to the contrary is an offence.

Each underwriter has represented, warranted and agreed that it has not offered, sold or distributed and will not offer, sell or distribute any Securities, directly or indirectly, in Canada or to or for the benefit of any resident of Canada, other than in compliance with applicable securities laws and, without limiting the generality of the foregoing:

S-110

Listing

Application has been made to Euronext Dublin for the Securities to be admitted to the Official List and to trading on the GEM, which is the exchange-regulated market of Euronext Dublin. The Securities are a new issue of securities with no established trading market. The underwriters have advised us that the underwriters currently intend to make a market in the Securities, as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the Securities and may discontinue any such market-making at any time at their sole discretion. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the Securities or that an active public market for the Securities will develop. If an active public trading market for the Securities does not develop, the market price and liquidity of the Securities may be adversely affected.

Conflicts of Interest

HSI is an affiliate of HSBC Holdings, and, as such, is deemed to have a “conflict of interest” under FINRA Rule 5121. Accordingly, the offering of the Securities is being conducted in compliance with the requirements of FINRA Rule 5121 (addressing conflicts of interest when distributing the securities of an affiliate) as administered by the Financial Industry Regulatory Authority (“FINRA”). Neither HSI nor any of our other affiliates will sell any Securities into any of its discretionary accounts without the prior specific written approval of the accountholder.

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, commercial and investment banking and other commercial dealings in the ordinary course of business with us. They have received customary fees and commissions for these transactions.

Market-Making Resales by Affiliates

This prospectus supplement together with the accompanying prospectus and your confirmation of sale may also be used by HSI in connection with offers and sales of the Securities in market-making transactions at negotiated prices related to prevailing market prices at the time of sale. In a market-making transaction, HSI may resell a security it acquires from other securityholders after the original offering and sale of the Securities.

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, HSI may act as principal or agent, including as agent for the counterparty in a transaction in which HSI acts as principal, or as agent for both

S-111

counterparties in a transaction in which HSI does not act as principal. HSI may receive compensation in the form of discounts and commissions, including from both counterparties in some cases. Other of our affiliates may also engage in transactions of this kind and may use this prospectus supplement and the accompanying prospectus for this purpose. Neither HSI, nor any other of our affiliates, have an obligation to make a market in the Securities and, if commenced, may discontinue any market-making activities at any time without notice, in their sole discretion.

Furthermore, HSI may be required to discontinue its market-making activities during periods when we are seeking to sell certain of our securities or when HSI, such as by means of its affiliation with us, learns of material non-public information relating to us. HSI would not be able to recommence its market-making activities until such sale has been completed or such information has become publicly available. It is not possible to forecast the impact, if any, that any such discontinuance may have on the market for the Securities. Although other broker-dealers may make a market in the Securities from time to time, there can be no assurance that any other broker-dealer will do so at any time when HSI discontinues its market-making activities. In addition, any such broker-dealer that is engaged in market-making activities may thereafter discontinue such activities at any time at its sole discretion.

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.

In connection with any use of this prospectus supplement and the accompanying prospectus by HSI or another of our affiliates, you may assume this prospectus supplement and the accompanying prospectus is being used in a market-making transaction unless otherwise specified.

These market activities have occurred and are expected to continue to occur both outside and inside the United States, solely in the ordinary course of business and not in contemplation of the offering of the Securities. In addition, our affiliates may, under certain circumstances, participate in the offering of the Securities.

Prohibition of Sales to EEA Retail Investors

If the applicable prospectus supplement includes a section entitled “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 (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 Directive 2014/65/EU (as amended, “MiFID II”); (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; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (the “Prospectus Regulation”). 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.

This prospectus has been prepared on the basis that any offer of securities in the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to produce a prospectus for offers of securities. Accordingly any person making or intending to make an offer in the EEA of securities which are the subject of an offering contemplated in this prospectus as completed by the applicable prospectus supplement in relation to the offer of those securities may only do so in circumstances in which no obligation arises for us or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation, in each case, in relation to such offer. Neither we nor any of the underwriters have authorized, nor do we or any of the underwriters authorize, the making of any offer of the securities in circumstances in which an obligation arises for us or the underwriters to publish a prospectus for such offer. Neither we nor the underwriters have authorized, nor do we authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters which constitute the final placement of the securities contemplated in this prospectus.

In connection with any issue of securities through this prospectus, the person(s) (if any) named as the stabilization manager(s) in the applicable prospectus supplement (the “stabilization manager”) (or any person acting on behalf of it) may, to the extent permitted by laws or regulations, over-allot securities or effect transactions with a view to supporting the market price of such securities at a level higher than that which might otherwise prevail. However, stabilization may not necessarily occur. Any stabilization action may begin on or after the date on which adequate public disclosure of the terms of any offer of the relevant securities is made and, if begun, may cease at any time, but it must end no later than the earlier of 30 days after the date of the issuance and 60 days after the date of the allotment of any relevant securities. Any stabilization action or over-allotment must be conducted by the relevant stabilization manager (or any person acting on behalf of it) in accordance with all applicable laws and rules.

Where the applicable prospectus supplement includes a section entitled “MiFID II product governance,” it will outline the target market assessment in respect of the securities and which channels for distribution of the securities are appropriate. Any person subsequently offering, selling or recommending the securities (a “distributor”) should take into consideration the target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the securities (by either adopting or refining the target market assessment made in respect of such securities) and determining appropriate distribution channels.

For the purpose of the Markets in Financial Instruments Directive product governance rules under EU Delegated Directive 2017/593 (the “MiFID Product Governance Rules”), a determination will be made in relation to each issue about whether any underwriter or dealer subscribing for any securities is a manufacturer in respect of such securities, but otherwise neither the underwriters nor the dealers nor any of their respective affiliates will be a manufacturer for the purpose of the MiFID Product Governance Rules.

Prohibition of Sales to UK Retail Investors

If the applicable prospectus supplement includes a section entitled “Prohibition of sales to UK 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 United Kingdom (“UK”). 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 UK domestic law by virtue of the European Union (Withdrawal) Act 2018, as amended (the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (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 UK domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of UK domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of UK domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

This prospectus has been prepared on the basis that any offer of securities in the UK will be made pursuant to an exemption under Section 86 of the FSMA from the requirement to produce a prospectus for offers of securities. Accordingly any person making or intending to make an offer in the UK of securities which are the subject of an offering contemplated in this prospectus as completed by the applicable prospectus supplement in relation to the offer of those securities may only do so in circumstances in which no obligation arises for us or any of the underwriters to publish a prospectus pursuant to Section 85 of the FSMA or supplement a prospectus pursuant to Article 23 of the UK Prospectus Regulation, in each case, in relation to such offer. Neither we nor any of the underwriters have authorized, nor do we or any of the underwriters authorize, the making of any offer of the securities in circumstances in which an obligation arises for us or the underwriters to publish a prospectus for such offer. Neither we nor the underwriters have authorized, nor do we authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters which constitute the final placement of the securities contemplated in this prospectus.

Where the applicable prospectus supplement includes a section entitled “UK MiFIR product governance,” it will outline the target market assessment in respect of the securities and which channels for distribution of the securities are appropriate. A distributor should take into consideration the target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK MiFIR Product Governance Rules”) is responsible for undertaking its own target market assessment in respect of the securities (by either adopting or refining the target market assessment) and determining appropriate distribution channels.

A determination will be made in relation to each issue about whether, for the purpose of the UK MiFIR Product Governance Rules, any underwriter or dealer subscribing for any securities is a manufacturer in respect of such security, but otherwise neither the underwriters nor the dealers nor any of their respective affiliates will be a manufacturer for the purpose of the UK MIFIR Product Governance Rules.

This document is for distribution only to persons who (i) have professional experience in matters relating to investments and who fall within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Financial Promotion Order”), (ii) fall within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc.”) of the Financial Promotion Order, (iii) are outside the UK or (iv) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) in connection with the issue or sale of any securities may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as “relevant persons”). This document is directed only at relevant persons and must not be acted on or relied on by persons

2

who are not relevant persons. Any investment or investment activity to which this document relates is available only to relevant persons and will be engaged in only with relevant persons.

Important Notice to Prospective Investors Pursuant to Paragraph 21 of the Hong Kong SFC Code of Conduct

Prospective investors should be aware that certain intermediaries in the context of certain offerings of securities contemplated by this prospectus as completed by the applicable prospectus supplement (each such offering, a “CMI Offering”), including certain underwriters, are “capital market intermediaries” (“CMIs”) subject to Paragraph 21 of the Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (the “SFC Code”). This notice to prospective investors is a summary of certain obligations the SFC Code imposes on such CMIs, which require the attention and cooperation of prospective investors.

Certain CMIs may also be acting as “overall coordinators” (“OCs”) for a CMI Offering and are subject to additional requirements under the SFC Code. The application of these obligations will depend on the role(s) undertaken by the relevant underwriter(s) in respect of each CMI Offering.

Prospective investors who are the directors, employees or major shareholders of HSBC Holdings, a CMI or its group companies would be considered under the SFC Code as having an association (“Association”) with HSBC Holdings, the CMI or the relevant group company. Prospective investors associated with HSBC Holdings or any CMI (including its group companies) should specifically disclose this when placing an order for the relevant securities and should disclose, at the same time, if such orders may negatively impact the price discovery process in relation to the relevant CMI Offering. Prospective investors who do not disclose their Associations are hereby deemed not to be so associated. Where prospective investors disclose their Associations but do not disclose that such order may negatively impact the price discovery process in relation to the relevant CMI Offering, such order is hereby deemed not to negatively impact the price discovery process in relation to the relevant CMI Offering.

Prospective investors should ensure, and by placing an order prospective investors are deemed to confirm, that orders placed are bona fide, are not inflated and do not constitute duplicated orders (i.e. two or more corresponding or identical orders placed via two or more CMIs). If a prospective investor is an asset management arm affiliated with any relevant underwriter, such prospective investor should indicate when placing an order if it is for a fund or portfolio where the relevant underwriter or its group company has more than 50% interest, in which case it will be classified as a “proprietary order” and subject to appropriate handling by CMIs in accordance with the SFC Code and should disclose, at the same time, if such “proprietary order” may negatively impact the price discovery process in relation to the relevant CMI Offering. Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. If a prospective investor is otherwise affiliated with any relevant underwriter, such that its order may be considered to be a “proprietary order” (pursuant to the SFC Code), such prospective investor should indicate to the relevant underwriter when placing such order. Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. Where prospective investors disclose such information but do not disclose that such “proprietary order” may negatively impact the price discovery process in relation to the relevant CMI Offering, such “proprietary order” is hereby deemed not to negatively impact the price discovery process in relation to the relevant CMI Offering.

Prospective investors should be aware that certain information may be disclosed by CMIs (including private banks) which is personal and/or confidential in nature to the prospective investor. By placing an order, prospective investors are deemed to have understood and consented to the collection, disclosure, use and transfer of such information by the relevant underwriter and/or any other third parties as may be required by the SFC Code, including to HSBC Holdings, any OCs, relevant regulators and/or any other third parties as may be required by the SFC Code, it being understood and agreed that such information shall only be used for the purpose of complying with the SFC Code, during the bookbuilding process for the relevant CMI Offering. Failure to provide such information may result in that order being rejected.

These financial statements are also prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”), including interpretations issued by the IFRS Interpretations Committee, as there are no applicable differences from IFRS Accounting Standards for the periods presented. As of December 31, 2023, there were no unendorsed standards effective for the year ended December 31, 2023 affecting the consolidated financial statements included in our Annual Report on Form 20-F for the year ended December 31, 2023, filed with the SEC on February 22, 2024 (the “2023 Form 20-F”).

We use the U.S. dollar as our presentation currency in our consolidated financial statements because the U.S. dollar and currencies linked to it form the major currency bloc in which we transact and fund our business.

With the exception of the capital ratios presented under “HSBC,” the financial information presented in this document complies with the UK-adopted international accounting standards, the requirements of the UK Companies Act 2006 and with international financial reporting standards adopted pursuant to Regulation (EC) No 1606/2002 as it applies in the EU.

LIMITATION ON ENFORCEMENT OF U.S. LAWS AGAINST US, OUR

MANAGEMENT AND OTHERS

We are an English public limited company. Most of our directors and executive officers (and certain experts named in this prospectus or in documents incorporated herein by reference) are resident outside the United States, and a substantial portion of our assets and the assets of such persons are located outside the United States. As a result, it may not be possible for you to effect service of process within the United States upon these persons or to enforce against them or us in U.S. courts judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by our English solicitors, Cleary Gottlieb Steen & Hamilton LLP, that there is doubt as to enforceability in the English courts, in original actions or in actions for enforcement of judgments of U.S. courts, of liabilities predicated solely upon the federal securities laws of the United States. In addition, awards of punitive damages in actions brought in the United States or elsewhere may not be enforceable in the UK. The enforceability of any judgment in the UK will depend on the particular facts of the case in effect at the time.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein contain both historical and forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Forward-looking statements may be identified by the use of terms such as “believes,” “expects,” “estimate,” “may,” “intends,” “plan,” “will,” “should,” “potential,” “seek,” “reasonably possible” or “anticipates” or the negative thereof or similar expressions, or by discussions of strategy.

These forward-looking statements include statements relating to the implementation and exercise of the UK bail-in powers; changes in the general economic conditions in the markets in which the HSBC Group operates, such as new, continuing or deepening recessions and prolonged inflationary pressures; the impact of the Russia-Ukraine war and the Israel-Hamas war on the global markets generally and the HSBC Group in particular; geopolitical tensions in the countries in which the HSBC Group operates, including those arising as a result of the Russia-Ukraine war and the Israel-Hamas war; and the UK’s relationship with the EU. We have based the forward-looking statements on current expectations and projections about future events. These forward-looking statements are subject to risks, uncertainties and assumptions about us, as described under “Cautionary statement regarding forward-looking statements” contained in the 2023 Form 20-F. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed herein might not occur. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of their dates. Additional information, including information on factors which may affect HSBC’s business, is contained in the 2023 Form 20-F.

DESCRIPTION OF DEBT SECURITIES

Debt securities offered through this prospectus will be issued under one of three indentures among HSBC Holdings, as issuer, The Bank of New York Mellon, as trustee and HSBC Bank USA, National Association, as paying agent, registrar and exchange rate agent, as heretofore supplemented and amended. The dated subordinated debt securities will be issued under the indenture for dated subordinated debt securities, the undated subordinated debt securities will be issued under the indenture for undated subordinated debt securities and the senior debt securities will be issued under the indenture for senior debt securities. The following summary of certain provisions of the debt securities and the indentures and any such summary in any prospectus supplement do not purport to be complete and are subject to, and are qualified by reference to, all the provisions of the debt securities and the relevant indenture. Defined terms used in this section but not otherwise defined in this prospectus have the meanings assigned to them in the relevant indenture.

General

The indentures do not limit the amount of debt securities that we may issue under them and provide that we may issue debt securities from time to time in one or more series.

Please refer to the prospectus supplement relating to the particular series of debt securities offered through this prospectus for the following terms, where applicable, of such debt securities:

11

Debt securities of any series may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates, may be redeemable at a premium, or may be otherwise designated by us as issued with original issue discount. We will discuss certain tax considerations that may be relevant to holders of such discount securities, undated or perpetual debt securities and debt securities providing for indexed, contingent or variable payments or payments in a currency other than the currency in which such debt securities are denominated in the prospectus supplement relating to such securities.

Debt securities and any coupons relating to such debt securities will become void unless presented for payment within 10 years with respect to a payment of principal and premium, if any, and five years with respect to a payment of interest. All monies paid by us to a paying agent or the trustee for the payment of principal of (and premium, if any, on) or any interest on any debt security that remain unclaimed at the end of two years after such principal, premium, or interest will have become due and payable will be repaid to us, and the holder of such debt security must look to us for payment thereof.

Form, Settlement and Clearance

General. Unless the relevant prospectus supplement states otherwise, the debt securities will initially be represented by one or more global securities in registered form, without coupons attached, and will be deposited with or on behalf of one or more depositaries, including, without limitation, The Depository Trust Company (“DTC”), Euroclear Bank SA/NV (“Euroclear”) and/or Clearstream Banking S.A. (“Clearstream Luxembourg”), and will be registered in the name of such depositary or its nominee. Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to persons who are registered as holders of the debt securities. Unless and until the debt securities are exchanged in whole or in part for other securities that we issue or the global securities are exchanged for definitive securities, the global securities may not be transferred except as a whole by the depositary to a nominee or a successor of the depositary.

The debt securities may be accepted for clearance by DTC, Euroclear and Clearstream Luxembourg. Unless the relevant prospectus supplement states otherwise, the initial distribution of the debt securities will be cleared through DTC only. In such event, beneficial interests in the global debt securities will be shown on, and transfers thereof will be effected only through, the book-entry records maintained by DTC and its direct and indirect participants, including, as applicable, Euroclear and Clearstream Luxembourg.

The laws of some states may require that certain investors in securities take physical delivery of their securities in definitive form. Those laws may impair the ability of investors to own interests in book-entry securities.

12

So long as the depositary, or its nominee, is the holder of a global debt security, the depositary or its nominee will be considered the sole holder of such global debt security for all purposes under the relevant indenture. Except as described below under the heading “—Definitive Debt Securities,” no participant, indirect participant or other person will be entitled to have debt securities registered in its name, receive or be entitled to receive physical delivery of debt securities in definitive form or be considered the owner or holder of the debt securities under the relevant indenture. Each person having an ownership or other interest in debt securities must rely on the procedures of the depositary, and, if a person is not a participant in the depositary, must rely on the procedures of the participant or other securities intermediary through which that person owns its interest to exercise any rights and obligations of a holder under the relevant indenture or the debt securities.

DTC has advised us that: DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants deposit with DTC. DTC also facilitates settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts thereby eliminating the need for physical movement of securities certificates. Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to the DTC system is also available to others such as securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Payments on the Global Debt Security. Payments of any amounts in respect of any global debt securities will be made by the paying agent to the depositary. Payments will be made to beneficial owners of debt securities in accordance with the rules and procedures of the depositary or its direct and indirect participants, as applicable. Neither we nor the trustee nor any of our agents will have any responsibility or liability for any aspect of the records of any securities intermediary in the chain of intermediaries between the depositary and any beneficial owner of an interest in a global debt security, or the failure of the depositary or any intermediary to pass through to any beneficial owner any payments that we make to the depositary.

All such payments will be distributed without deduction or withholding for any UK taxes or other UK governmental charges, or if any such deduction or withholding is required to be made under the provisions of any applicable UK law or regulation, then, except as described under “Additional Amounts,” such additional amounts will be paid as may be necessary in order that the net amounts received by any holder of the global debt security and by the owners of interests in the debt securities, after such deduction or withholding, will equal the net amounts that such holder and owners would have otherwise received in respect of the global debt security or interests in the debt securities, as the case may be, if such deduction or withholding had not been made.

Settlement. Initial settlement for the debt securities and settlement of any secondary market trades in the debt securities will be made in same-day funds. The debt securities will settle in DTC’s Same-Day Funds Settlement System.

Definitive Debt Securities. Owners of interests in the debt securities will be entitled to receive definitive debt securities in registered form in respect of such interest if: (1) (i) DTC notifies us in writing that it is unwilling to or unable to continue as a depositary for the debt securities of such series or the debt securities, as the case may be, or (ii) if at any time DTC ceases to be eligible as a “clearing agency” registered under the Exchange Act or we become aware of such ineligibility and, in either case, a successor is not appointed by us within 90 days; or (2) an event of default has occurred and is continuing and the registrar has received a request from DTC; or (3) the applicable prospectus supplement provides otherwise with respect to a particular series.

Unless otherwise indicated in the applicable prospectus supplement, definitive debt securities will be issued in denominations of $1,000 or integral multiples of $1,000 and will be issued in registered form. Such definitive

13

debt securities will be registered in the name or names of such person or persons as the registrar will notify the trustee based on the instructions of DTC.

Payments

Any payments of interest and, in the case of dated subordinated debt securities and senior debt securities, principal and premium (if any), on any particular series of debt securities will be made on such dates and, in the case of payments of interest, at such rate or rates, as are set forth in, or as are determined by the method of calculation described in, the prospectus supplement relating to the debt securities of such series.

Undated Subordinated Debt Securities. We are not required to make payments with respect to any series of undated subordinated debt securities on any payment date specified for such payment in the prospectus supplement relating to the debt securities of such series. Failure to make any such payment on any such payment date will not constitute a default by us for any purpose. Any payment not made by us in respect of any series of undated subordinated debt securities on any applicable payment date, together with any other unpaid payments, will, so long as they remain unpaid, constitute “missed payments” and will accumulate until paid. Missed payments will not bear interest.

Missed payments, if any, may be paid at our option in whole or in part at any time on not less than 14 days’ notice to the trustee, but all missed payments in respect of all undated subordinated debt securities of a particular series at the time outstanding will (subject to any solvency condition) become due and payable in full on whichever is the earliest of:

If we give notice of our intention to pay the whole or part of the missed payments on the undated subordinated debt securities of any series, we will be obliged, subject to any solvency condition, to do so upon the expiration of such notice. Where missed payments in respect of undated subordinated debt securities of any series are paid in part, each part payment will be deemed to be in respect of the full amount of missed payments accrued relating to the earliest payment date or consecutive payment dates in respect of such undated subordinated debt securities.

If we are unable to make any payment on or with respect to the undated subordinated debt securities of any series because we are not able to satisfy a solvency condition, the amount of any such payment which would otherwise be payable will be available to meet our losses. In the event of our winding up, the right to claim for interest, including missed payments, and any other amount payable on such undated subordinated debt securities may be limited by applicable insolvency law.

Computation of Interest. Except as otherwise specified in the prospectus supplement with respect to the debt securities of any series, any interest on the debt securities of each series, which is not denominated in Euro, will be computed on the basis of a 360-day year of twelve 30-day months. Interest on debt securities of each series denominated in Euro will be computed on the basis of the actual number of days in the calculation period divided by 365 (or, if any portion of that calculation period falls in a leap year, the sum of (a) the actual number of days in that portion of the calculation period falling in a leap year, divided by 366 and (b) the actual number of days in that portion of the calculation period falling in a non-leap year, divided by 365).

Additional Amounts

Senior Debt Securities

Unless the relevant prospectus supplement provides otherwise, all payments made under or with respect to any senior debt securities shall be paid by us without deduction or withholding for, or on account of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions or withholdings whatsoever imposed,

14

levied, collected, withheld or assessed by or on behalf of the UK or any political subdivision or taxing authority thereof or therein having the power to tax (each, a “Taxing Jurisdiction”), unless required by law. If such deduction or withholding shall at any time be required by the law of the Taxing Jurisdiction, we shall pay such additional amounts (“Additional Amounts”) in respect of any payments of interest only (and not principal) on such senior debt securities as may be necessary so that the net amounts (including Additional Amounts) paid to the holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the holders would have been entitled to receive in respect of such senior debt securities in the absence of such deduction or withholding, provided that the foregoing shall not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which:

if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding or deduction of all or part of the tax, duty, assessment or other governmental charge;

Unless the relevant prospectus supplement provides otherwise, all payments in respect of the senior debt securities will be made subject to any withholding or deduction required pursuant to (i) sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended, or any associated regulations or other official guidance; (ii) any treaty, law, regulation or other official guidance enacted in any other jurisdiction, or relating to an intergovernmental agreement between the United States and any other jurisdiction, which (in either case) facilitates the implementation of clause (i); or (iii) any agreement pursuant to the implementation of clauses (i) or

15

(ii) with the U.S. Internal Revenue Service, the U.S. government or any governmental or taxation authority in any other jurisdiction (collectively, “FATCA”) and we will not be required to pay any Additional Amounts on account of any such deduction or withholding required pursuant to FATCA.

With respect to any series of senior debt securities, any paying agent shall be entitled to make a deduction or withholding from any payment which it makes under the senior debt securities of such series 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 deduction or withholding required by FATCA (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. However, such deduction or withholding shall not apply to payments made under the senior debt securities of such series and this prospectus through the relevant clearing systems. 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 provision shall be treated as paid to the holder of a senior debt security, and we shall not pay Additional Amounts in respect of such deduction or withholding, except to the extent these provisions explicitly provide otherwise.

Dated Subordinated Debt Securities

Unless the relevant prospectus supplement provides otherwise, all payments made under or with respect to any dated subordinated debt securities shall be paid by us without deduction or withholding for, or on account of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on behalf of the Taxing Jurisdiction, unless required by law. If such deduction or withholding shall at any time be required by the law of the Taxing Jurisdiction, we shall pay such Additional Amounts in respect of any payments of interest only (and not principal) on such dated subordinated debt securities as may be necessary so that the net amounts (including Additional Amounts) paid to the holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the holders would have been entitled to receive in respect of such dated subordinated debt securities in the absence of such deduction or withholding, provided that the foregoing shall not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which:

16

if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding or deduction of all or part of the tax, duty, assessment or other governmental charge;

Unless the relevant prospectus supplement provides otherwise, all payments in respect of the dated subordinated debt securities will be made subject to any withholding or deduction required pursuant to FATCA and we will not be required to pay any Additional Amounts on account of any such deduction or withholding required pursuant to FATCA.

With respect to any series of dated subordinated debt securities, any paying agent shall be entitled to make a deduction or withholding from any payment which it makes under the dated subordinated debt securities of such series and the relevant indenture for or on account of 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. However, such deduction or withholding shall not apply to payments made under the dated subordinated debt securities of such series and this prospectus through the relevant clearing systems. 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 provision shall be treated as paid to the holder of a dated subordinated debt security, and we shall not pay Additional Amounts in respect of such deduction or withholding, except to the extent these provisions explicitly provide otherwise.

Undated Subordinated Debt Securities

Unless the relevant prospectus supplement provides otherwise, all payments made under or with respect to any undated subordinated debt securities shall be paid by us without deduction or withholding for, or on account of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on behalf of the Taxing Jurisdiction, unless required by law. If such deduction or withholding shall at any time be required by the law of the Taxing Jurisdiction, we shall pay such Additional Amounts in respect of any payments of interest and related deferred payments and missed payments, if any, only (and not principal) on such undated subordinated debt securities as may be necessary so that the net amounts (including Additional Amounts) paid to the holders, after such deduction or withholding, shall be equal to the respective amounts of interest and related deferred payments and missed payments, if any, which the holders would have been entitled to receive in respect of such undated subordinated debt securities in the absence of such deduction or withholding, provided that the foregoing shall not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which:

17

if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding or deduction of all or part of the tax, duty, assessment or other governmental charge;

Unless the relevant prospectus supplement provides otherwise, all payments in respect of the undated subordinated debt securities will be made subject to any withholding or deduction required pursuant to FATCA and we will not be required to pay any Additional Amounts on account of any such deduction or withholding required pursuant to FATCA.

With respect to any series of undated subordinated debt securities, any paying agent shall be entitled to make a deduction or withholding from any payment which it makes under the undated subordinated debt securities of such series and the relevant indenture for or on account of 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. However, such deduction or withholding shall not apply to payments made under the undated subordinated debt securities of such series and this prospectus through the relevant clearing systems. 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 provision shall be treated as paid to the holder of an undated subordinated debt security, and we shall not pay Additional Amounts in respect of such deduction or withholding, except to the extent these provisions explicitly provide otherwise.

General

We have agreed in each indenture that at least one paying agent for each series of debt securities will be located outside the UK.

18

Whenever in this prospectus there is mentioned, in any context, the payment of interest, if any, or in the case of undated subordinated debt securities, the related deferred payments and missed payments, if any, on, or in respect of, any debt securities of any series or the net proceeds received on the sale or exchange of any debt security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this prospectus to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the terms of the indenture and the provisions described in this prospectus for any debt securities and as if express mention of the payment of Additional Amounts (if applicable) were made in any provision thereof where such express mention is not made.

Redemption

Any terms of the redemption of any series of debt securities, whether at our option or upon the occurrence of certain circumstances (including, but not limited to, the occurrence of certain tax or regulatory events), will be set forth in the relevant prospectus supplement.

Any redemption of the undated subordinated debt securities may be subject to one or more solvency conditions, as specified in the relevant prospectus supplement.

We and any of our subsidiary undertakings may, in accordance with applicable law, repurchase debt securities for our or their account. Under the provisions of UK CRR, as applied by the UK Prudential Regulation Authority or any successor entity (the “PRA”) and the Bank of England at the date of this prospectus, any optional tax redemption and any other optional redemption or repurchase may require the prior consent of the Relevant Regulator or the relevant UK resolution authority, as applicable.

For these purposes:

Optional Redemption in the Event of Change in Tax Treatment

In addition to, and unless otherwise stated in, the redemption provisions set forth in the prospectus supplement relating to the debt securities of a series, the debt securities of any series may be redeemed, in whole but not in part, at our option, on not less than 10 nor more than 60 days’ notice, at any time at a redemption price equal to 100% of the principal amount (or in the case of index-linked debt securities, face amount) thereof (and premium, if any), together with accrued but unpaid interest, if any, in respect of such debt securities, to (but excluding) the date fixed for redemption (or, in the case of discounted securities, the accreted face amount

19

thereof, together with accrued interest, if any, or, in the case of index-linked debt securities, the amount specified in the related prospectus supplement) and any debt securities convertible into preference shares or other securities may, at our option, be converted as a whole, if, at any time, we determine that:

provided, however, that, in the case of (a) above, no notice of redemption will be given earlier than 90 days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment in respect of such debt securities then due.

Modification and Waiver

Modifications of and amendments to the relevant indenture with respect to the debt securities may be made by us and the trustee, without the consent of the holders of the debt securities of such series for certain purposes and otherwise with the consent of the holders of a majority in principal amount (or in the case of index-linked debt securities, face amount) of the debt securities of such series then outstanding; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby:

20

The holders of not less than a majority in principal amount (or, in the case of any principal indexed debt securities, face amount) of the outstanding debt securities of a series may, on behalf of all holders of debt securities of that series, waive, insofar as that series is concerned, our compliance with certain restrictive provisions of the indenture before the time for such compliance.

In addition, material variations in the terms and conditions of debt securities of any series, including modifications relating to subordination, redemption and events of default may require the consent of the PRA.

Senior Debt Securities—Defaults and Events of Default

The senior debt securities will be our direct, unsecured obligations and rank pari passu with our other senior unsecured indebtedness, and the senior debt securities of a series will rank equally and ratably without any preference among themselves. Senior indebtedness will not include any indebtedness that is expressed to be subordinated to or pari passu with the subordinated debt securities.

The maturity of the senior debt securities will be subject to acceleration only as specified under “—Defaults and Events of Default” below.

Defaults and Events of Default. Unless otherwise provided in a prospectus supplement with respect to any series of senior debt securities, it will be an event of default with respect to senior debt securities of a series if:

Unless otherwise provided in a prospectus supplement with respect to any series of senior debt securities and subject to the paragraph below relating to circumstances in which a relevant failure will not be a default, it will be a default with respect to senior debt securities of a series if any one of the following events occurs:

21

If a default occurs, the trustee may institute proceedings in England (but not elsewhere) for our winding-up; provided that the trustee may not, upon the occurrence of a default, accelerate the maturity of any outstanding senior debt securities of a series, unless an event of default has occurred and is continuing.

Notwithstanding the foregoing, failure to make any payment with respect to any senior debt securities of a series will not be a default with respect to the senior debt securities of such series if such payment is withheld or refused:

provided, however, that the trustee may, by notice to us, require us to take such action (including but not limited to proceedings for a declaration by a court of competent jurisdiction) as the trustee may be advised in an opinion of counsel, upon which opinion the trustee may conclusively rely, is appropriate and reasonable in the circumstances to resolve such doubt, in which case we will forthwith take and expeditiously proceed with such action and will be bound by any final resolution of the doubt resulting therefrom. If any such resolution determines that the relevant payment can be made without violating any applicable law, regulation or order then the preceding sentence will cease to have effect and the payment will become due and payable on the expiration of the relevant grace period of 30 days after the trustee gives written notice to us informing us of such resolution.

If an event of default occurs and is continuing with respect to a series of senior debt securities, the trustee may or, if requested by the holder or holders of not less than 25% in aggregate principal amount of the outstanding senior debt securities of such series, will declare the principal amount (or such other amount as is specified in the prospectus supplement) together with accrued but unpaid interest (or, in the case of discounted securities, the accreted face amount thereof, together with accrued interest, if any, or, in the case of index-linked debt securities, the amount specified in the related prospectus supplement) with respect to the outstanding senior debt securities of such series to be due and payable immediately, by a notice in writing to us (and to the trustee if given by the holders), and upon any such declaration such principal amount (or specified amount) will become immediately due and payable; provided that after such declaration, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding senior debt securities of the series, by written notice to us and the trustee, may (under certain circumstances) rescind and annul such declaration.

Under the terms of the relevant indenture and the senior debt securities of a series, the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the senior debt securities of such series will not be stated to be an event of default or a default. As a result, holders will not have the right to request that the trustee declare an acceleration or institute proceedings for our winding up solely due to the exercise of the UK bail-in power by the relevant UK resolution authority.

After the end of each fiscal year, we will furnish to the trustee a certificate of certain officers as to the absence of an event of default under the relevant indenture, as the case may be, specifying any such event of default.

Subordinated Debt Securities—Subordination, Defaults and Events of Default

The subordinated debt securities will be our direct, unsecured obligations, and the subordinated debt securities of a series will rank equally and ratably without any preference among themselves. Our obligations

22

pursuant to the subordinated debt securities will be subordinate in right of payment to claims of our depositors and all our other creditors other than claims which are by their terms, or are expressed to be, subordinated to, or pari passu with, the subordinated debt securities as described below under “ —Subordination; Dated Subordinated Debt Securities” and “—Subordination; Undated Subordinated Debt Securities.”

The maturity of the dated subordinated debt securities and the payment of principal of the undated subordinated debt securities will be subject to acceleration only in the event of our winding up or if an effective resolution is validly adopted by our shareholders for our winding up. See “ —Defaults and Events of Default” below.

Subordination; Dated Subordinated Debt Securities. The rights of holders of dated subordinated debt securities will, in the event of our winding up, be subordinated in right of payment to claims of our depositors and all our other creditors other than claims which are by their terms, or are expressed to be, subordinated to the dated subordinated debt securities (including the undated subordinated debt securities) or pari passu therewith. The subordination provisions of the dated subordinated indenture, and to which the dated subordinated debt securities will be subject, will be governed by, and construed in accordance with, the laws of England and Wales.

Subordination; Undated Subordinated Debt Securities. The rights of holders of undated subordinated debt securities will, in the event of our winding up, be subordinated in right of payment to claims of our depositors and all our other creditors other than claims which are by their terms, or are expressed to be, subordinated to, or pari passu with, the undated subordinated debt securities. The subordination provisions of the undated subordinated indenture, and to which the undated subordinated debt securities will be subject, will be governed by, and construed in accordance with, the laws of England and Wales. In the event of our winding up, holders of undated subordinated debt securities will be treated in the same way as they would be treated if they were holders of a class of preference shares in our capital having a preferential right to a return of assets in such winding up over the holders of all other classes of shares in our capital for the time being issued and outstanding; they will receive an amount equal to the principal amount of the undated subordinated debt securities of such series then outstanding together with accrued interest, if any, to the extent that a holder of such class of preference shares would receive an equivalent amount.

Defaults and Events of Default. Unless otherwise provided in a prospectus supplement with respect to any series of subordinated debt securities, it will be an event of default with respect to subordinated debt securities of a series if:

Unless otherwise provided in a prospectus supplement with respect to any series of dated subordinated debt securities and subject to the paragraph below relating to circumstances in which a relevant failure will not be a default, it will be a default with respect to dated subordinated debt securities of a series if any one of the following events occurs:

23

Unless otherwise provided in a prospectus supplement with respect to any series of undated subordinated debt securities and subject to the paragraph below relating to circumstances in which a relevant failure will not be a default, it will be a default with respect to undated subordinated debt securities of a series if:

If a default occurs, the trustee may institute proceedings in England (but not elsewhere) for our winding up provided that the trustee may not, upon the occurrence of a default on the subordinated debt securities, accelerate the maturity of any of the dated subordinated debt securities of the relevant series then outstanding or declare the principal of (or premium, if any, on) and any accrued but unpaid interest or missed payments of the undated subordinated debt securities of the relevant series then outstanding immediately due and payable, unless an event of default has occurred and is continuing. For the purposes of determining whether or not an event of default has occurred on the undated subordinated debt securities, a payment will not be deemed to be due on any date on which any solvency condition is not satisfied. However, if we fail to make the payments specified in (a) and (b) above, and at such time any solvency condition is not satisfied, the trustee may, upon the occurrence of a default, institute proceedings in England (but not elsewhere) for our winding up.

Notwithstanding the foregoing, failure to make any payment in respect of a series of subordinated debt securities will not be a default in respect of the subordinated debt securities of such series if such payment is withheld or refused:

provided, however, that the trustee may, by notice to us, require us to take such action (including but not limited to proceedings for a declaration by a court of competent jurisdiction) as the trustee may be advised in an opinion of counsel, upon which opinion the trustee may conclusively rely, is appropriate and reasonable in the circumstances to resolve such doubt, in which case we will forthwith take and expeditiously proceed with such action and will be bound by any final resolution of the doubt resulting therefrom. If any such resolution determines that the relevant payment can be made without violating any applicable law, regulation or order then the preceding sentence will cease to have effect and the payment will become due and payable on the expiration of the relevant grace period of 30 days, after the trustee gives written notice to us informing us of such resolution.

If an event of default occurs and is continuing with respect to a series of subordinated debt securities, the trustee may or, if requested by the holder or holders of not less than 25% in aggregate principal amount of the outstanding subordinated debt securities of such series, will declare the principal amount (or such other amount as is specified in the prospectus supplement) together with accrued but unpaid payments with respect to the outstanding subordinated debt securities of such series to be due and payable immediately, by a notice in writing to us (and to the trustee if given by the holders), and upon any such declaration such principal amount (or specified amount) will become immediately due and payable; provided that after such declaration, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding subordinated debt securities of the series, by written notice to us and the trustee, may (under certain circumstances) rescind and annul such declaration.

Under the terms of the relevant indenture and the subordinated debt securities of a series, the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the subordinated debt securities of such

24

series will not be stated to be an event of default or a default. As a result, holders will not have the right to request that the trustee declare an acceleration or institute proceedings for our winding up solely due to the exercise of the UK bail-in power by the relevant UK resolution authority.

After the end of each fiscal year, we will furnish to the trustee a certificate of certain officers as to the absence of an event of default or a default under the relevant indenture, as the case may be, specifying any such event of default or default.

No Right of Set-Off by Holders

Subject to applicable law and unless the applicable prospectus supplement provides otherwise, holders of debt securities, by their acceptance thereof, and the trustee, in respect of any claims of such holders to payment of any principal, premium or interest in respect of any debt securities, will be deemed to have waived any right of set-off or counterclaim that they might otherwise have. Notwithstanding the preceding sentence, if any of the rights and claims of any holder of debt securities are discharged by set-off, such holder will immediately pay an amount equal to the amount of such discharge to us or, if applicable, the liquidator or trustee or receiver in our bankruptcy and, until such time as payment is made, will hold a sum equal to such amount in trust for us or, if applicable, the liquidator or trustee or receiver in our bankruptcy. Accordingly, such discharge will be deemed not to have taken place. The waiver of set-off provisions of the debt securities will be governed by, and construed in accordance with, the laws of England and Wales.

Waiver of Events of Default and Defaults

The holders of not less than a majority in aggregate principal amount (or, in the case of any principal indexed debt securities, face amount) of the outstanding debt securities of a series may, on behalf of all holders of debt securities of that series, waive any past event of default or default under the applicable indenture with respect to debt securities of that series, except a default in the payment of any principal of (or premium, if any, on) or any installment of interest or missed payment on any debt securities of that series and except a default in respect of a covenant or provision, the modification or amendment of which would require the consent of the holder of each outstanding debt security affected by it. Upon any such waiver, such event of default or default will cease to exist, and any event of default or default with respect to any series arising therefrom will be deemed to have been cured and not to have occurred; provided that no such waiver will extend to any subsequent or other event of default or default or impair any right consequent thereon.

Limitation on Remedies and Suits

No remedy against us other than as specifically provided by the relevant indenture will be available to the trustee or the holders of debt securities whether for the recovery of amounts owing in respect of such debt securities or under the relevant indenture or in respect of any breach by us of any obligation, condition or provision under the relevant indenture or such debt securities or otherwise.

No holder of debt securities will be entitled to proceed directly against us, except as described below.

Before a holder of any 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 any debt securities, the following must occur:

25

Notwithstanding any other provision of the indentures or debt securities, the right of any holder of debt securities to receive payment of the principal of (and premium, if any, on), or interest or missed payments on, such debt securities on or after the due dates thereof and to institute suit for the enforcement of any such payment on or after such respective dates, will not be impaired or affected without the consent of such holder.

Consolidation, Merger and Sale of Assets

We may, without the consent of the holders of any of the debt securities, consolidate or amalgamate with, or merge into, any corporation, or convey, sell, transfer or lease our properties and assets substantially as an entirety to any person, provided that:

Assumption of Obligations

Subject to applicable law and regulation (including, if and to the extent required by, in relation to the senior debt securities, the Loss Absorption Regulations or, in relation to the subordinated debt securities, the Applicable Rules at such time, obtaining any required permission of the Relevant Regulator or the relevant UK resolution authority (as applicable)), with respect to a series of debt securities, a holding company of us or any of our subsidiary undertakings may assume our obligations (or those of any corporation which will have previously assumed our obligations); provided, that:

Upon any such assumption, the successor entity will succeed to, and be substituted for, and may exercise all of our rights and powers under the relevant indenture with respect to the debt securities of such series with the same effect as if the successor entity had been named under the relevant indenture.

26

For these purposes:

Defeasance and Discharge

If so specified in the applicable prospectus supplement with respect to debt securities of a series that are payable only in U.S. dollars, we will be discharged from any and all obligations in respect of the debt securities of such series (with certain exceptions) if, at any time, inter alia, either

Any discharge will be subject to the consent of the PRA, if required.

If so specified in the applicable prospectus supplement with respect to dated subordinated securities or senior debt securities of a series that are payable only in U.S. dollars at our option, (i) we will be discharged from any obligations with respect to the dated subordinated securities or the senior debt securities of any series, as applicable, or (ii) we will cease to comply with the obligation to furnish to the trustee upon its request compliance certificates or opinions of counsel (“covenant defeasance”) (and any other restrictive covenant added in the prospectus supplement for the benefit of such series) if:

27

Any covenant defeasance will be subject to the consent of the PRA, if required.

Conversion

The prospectus supplement relating to a particular series of debt securities may provide for the exchange or conversion of such debt securities.

Except as otherwise specified in the prospectus supplement relating to a particular series of undated subordinated debt securities, we will have the option to convert, in whole but not in part, the undated subordinated debt securities of any series into preference shares on any payment date. The related prospectus supplement will describe the other terms and conditions of the conversion provisions.

Trustee’s Duties

Except during the continuance of an event of default or a default, the trustee will only be liable for performing those duties specifically set forth in the relevant indenture. In the event an event of default or default has occurred and is continuing, the trustee will exercise such of the rights and powers vested in it by the relevant indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

If an event of default or default occurs and is continuing with respect to the debt securities of a series, the trustee will be under no obligation to exercise any of the rights or powers vested in it by the relevant indenture at the request or direction of any of the holders of debt securities of such series, unless such holders have offered to the trustee reasonable security or indemnity satisfactory to the trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. Subject to such provisions for the indemnification of the trustee, the holders of a majority in aggregate principal amount (or, in the case of an index-linked debt security, the face amount) of the outstanding debt securities of a series will 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 the debt securities of such series. However, (i) this direction must not be in conflict with any rule of law or the relevant indenture and (ii) the trustee will have the right to decline to follow any such direction if the trustee in good faith, by a responsible officer of the trustee, determines that the proceeding so directed would be unjustly prejudicial to the holders of debt securities of such series not joining in any such direction. The trustee also may take any other action it deems proper, which is not inconsistent with such direction.

The trustee will, within 90 days after the occurrence of an event of default or default with respect to the debt securities of a series, give to the holders of the affected debt securities of such series notice of such event of default or default, unless such event of default or default has been cured or waived. However, the trustee will be protected in withholding such notice so long as the board of directors, the executive committee or a trust committee of directors and/or responsible officers of the trustee reasonably determines that the withholding of such notice is in the interest of the holders of debt securities of such series.

By its acquisition of the debt securities, each holder (which, for these purposes, includes each beneficial owner), to the extent permitted by the Trust Indenture Act 1939, as amended (the “Trust Indenture Act”), will waive any and all claims, in law and/or in equity, against the trustee for, agree not to initiate a suit against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of (i) the UK bail-in power by the relevant UK resolution authority with respect to the debt securities or (ii) the limited remedies available under the relevant indenture for a non-payment of principal and/or interest on the debt securities.

Following the exercise of a UK bail-in power by the relevant UK resolution authority (as defined below), the trustee’s duties will be different from those set forth herein and will be fully detailed in the relevant prospectus supplement.

Agreement with Respect to the Exercise of UK Bail-in Power

The debt securities will be subject to the exercise of the UK bail-in power by the relevant UK resolution authority as set forth in the applicable prospectus supplement. In particular, by its acquisition of the debt securities, each holder (which, for these purposes, includes each beneficial owner) will acknowledge, accept, consent and agree, notwithstanding any other term of the debt securities or the relevant indenture or any other agreements, arrangements, or understandings between us and any holder, to be bound by (a) the effect of the exercise of any UK bail-in power by the relevant UK resolution authority in relation to any debt securities that (without limitation) may include and result in any of the following, or some combination thereof: (i) the reduction of all, or a portion, of the Amounts Due; (ii) the conversion of all, or a portion, of the Amounts Due into our or another person’s ordinary shares, other securities or other obligations (and the issue to, or conferral on, the holder of such ordinary shares, other securities or other obligations), including by means of an amendment, modification or variation of the terms of the debt securities or the relevant indenture; (iii) the cancellation of the debt securities; and/or (iv) the amendment or alteration of, in the case of the senior debt securities or the dated subordinated debt securities, the maturity date, or in the case of the undated subordinated debt securities, the redemption date, or amendment of the amount of interest or missed payments payable on the debt securities, or the interest payment dates, including by suspending payment for a temporary period; and (b) the variation of the terms of the debt securities or the relevant indenture, if necessary, to give effect to the exercise of any UK bail-in power by the relevant UK resolution authority.

No repayment or payment of Amounts Due will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise. Moreover, each holder (which, for these purposes, includes each beneficial owner) will consent to the exercise of any UK bail-in power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to the debt securities.

For these purposes, “Amounts Due” are the principal amount of, and any accrued and unpaid interest or missed payments including any Additional Amounts, on, the debt securities. References to such amounts will include amounts that have become due and payable, but which have not been paid, prior to the exercise of any UK bail-in power by the relevant UK resolution authority.

The Banking Act specifies the order in which the bail-in tool should be applied, reflecting the hierarchy of capital instruments under the UK capital framework and otherwise respecting the hierarchy of claims in an ordinary insolvency.

Except as stated above, each indenture and the debt securities of each series will be governed by, and construed in accordance with, the laws of the State of New York. See “Subordinated Debt Securities— Subordination, Defaults and Events of Default” and “No Right of Set-Off by Holders.”

The contingent capital securities indenture does not limit the amount of contingent capital securities that we may issue under it and provides that we may issue contingent capital securities from time to time in one or more series.

The contingent capital securities will be our direct, unsecured and subordinated obligations. The contingent capital securities of each series will rank pari passu among themselves, without any preference one over the other by reason of the date they were issued or otherwise.
