Common Code 264860792

Sumitomo Mitsui Financial Group, Inc., a joint stock company (kabushiki kaisha) incorporated under the laws of Japan (the “Issuer”, which term includes any successor under the Indenture referred to on the reverse of this Security) for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of [                ] U.S. Dollars on July 13, 2026 (the “Maturity Date”) (subject to adjustments as set forth below) and to pay interest thereon from July 13, 2023 or from the most recent interest payment date to which interest has been paid or duly provided for, quarterly in arrears on January 13, April 13, July 13 and October 13 in each year (each, an “Interest Payment Date”) commencing October 13, 2023 at an interest rate equal to Compounded Daily SOFR plus a margin (the “Margin”) of 1.30% per annum, until the principal hereof is paid or made available for payment, all subject to and in accordance with the terms of the Indenture.

For the purposes of this Security, the term “Business Day” means any day that is a U.S. Government Securities Business Day and that in The City of New York, London and Tokyo, is not a day on which banking institutions are authorized or required by law, regulation or executive order to close. If any Interest Payment Date (other than the Maturity Date or any redemption date for taxation reasons as provided for on the reverse of this Security) falls on a day that is not a Business Day, such Interest Payment Date will be adjusted in accordance with the Modified Following Business Day Convention. The term “Modified Following Business Day Convention” means that the relevant date shall be postponed to the first following day that is a Business Day (and interest will continue to accrue to, but excluding, such succeeding Business Day), unless that day falls in the next calendar month in which case that date will be the first preceding day that is a Business Day (and interest will accrue to, but excluding, such preceding Business Day).

If the Maturity Date or redemption date for taxation reasons as provided for on the reverse of this Security would fall on a day that is not a Business Day, then any interest, principal or Additional Amounts, if any, as the case may be, will be paid on the next succeeding Business Day, and no interest shall accrue from and after the Maturity Date or such redemption date.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Security is registered as of the close of business on the fifteenth day before the Interest Payment Date (whether or not a Business Day). If and to the extent the Issuer shall default in the payment of the interest due on such Interest Payment Date, such defaulted interest shall be paid to the person in whose name this Security is registered at the close of business on a subsequent record date (which date shall not be less than five Business Days prior to the date of payment of such defaulted interest), established by notice given by mail by or on behalf of the Issuer to the Holder of this Security not less than 15 days preceding such subsequent record date. Interest on this Security will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid.

As further described on the reverse of this Security, on each Interest Determination Date, the Calculation Agent will calculate the amount of accrued interest payable on this Security on the related Interest Payment Date by multiplying (i) the outstanding principal amount of this Security by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the number of days in the relevant Interest Period divided by 360 and rounding the resulting figure to the nearest cent (half a cent being rounded upwards). Interest will be calculated per each $1,000 in nominal amount of the Securities and rounded to the nearest cent (half a cent being rounded upwards). In no event shall the rate of interest for this Security be less than 0% for any Interest Period.

The principal of, and interest and Additional Amounts on, the Securities will be payable in U.S. dollars. The Issuer will cause the Trustee, or the paying agent, if any, to pay such amounts, on the dates payment is to be made, directly to The Depository Trust Company (“DTC”).

The Issuer will pay the Holder hereof Additional Amounts with respect to withholding taxes as are provided for, and subject to the conditions stated, on the reverse of this Security.

This Security is being deposited with DTC acting as depository, and registered in the name of Cede & Co., a nominee of DTC. As Holder of record of this Security, Cede & Co. shall be entitled to receive payments of principal and interest. Payments of principal and interest, including any Additional Amounts, on this Security shall be made in the manner specified on the reverse hereof and, to the extent not inconsistent with the provisions set forth herein, in the Indenture referred herein.

The Securities constitute the direct, unconditional, unsecured and unsubordinated general obligations of the Issuer and shall at all times rank pari passu without any preference among themselves and with all other unsecured obligations of the Issuer, other than subordinated obligations of the Issuer and except for statutorily preferred obligations. The Securities are not redeemable prior to maturity, except as set forth on the reverse of this Security and will not be subject to any sinking fund.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been manually executed by or on behalf of the Trustee under the Indenture, this Security shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Issuer has caused this Security to be duly executed.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

with the resulting percentage being rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005 per cent. being rounded upwards (e.g., 9.876541 per cent.

“d_o” means the number of U.S. Government Securities Business Days in the relevant SOFR Observation Period;

“i” means a series of whole numbers ascending from one to d_o, representing each U.S. Government Securities Business Day in chronological order from (and including) the first U.S. Government Securities Business Day in the relevant SOFR Observation Period (each, a “U.S. Government Securities Business Day “i””);

“n_i”, for any U.S. Government Securities Business Day “i”, means the number of calendar days from (and including) such U.S. Government Securities Business Day “i” up to (but excluding) the following U.S. Government Securities Business Day;

“Interest Determination Date” means the date that is five Business Days before the related Interest Payment Date;

“SOFR” means, in respect of a U.S. Government Securities Business Day, the reference rate determined by the Calculation Agent in accordance with the following provision:

For the avoidance of doubt, in accordance with the Benchmark Transition Provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest payable for each Interest Period on this Security will be an annual rate equal to the sum of the Benchmark Replacement (as defined below) and the Margin.

The Bank of New York Mellon will serve as calculation agent (in such capacity together with any successor, the “Calculation Agent”) for the Securities. In the absence of gross negligence or willful default, the Calculation Agent’s determination of Compounded Daily SOFR and its calculation of the applicable interest rate for each Interest Period will be conclusive and binding on the Issuer and the Holders of the Securities. The Calculation Agent will make available the interest rates for current and preceding Interest Periods by delivery of such notice through such medium as is available to participants in DTC, Euroclear and Clearstream, or any successor thereof, and in accordance with such applicable rules and procedures as long as the Securities are held in global form.

In connection with the implementation of a Benchmark Replacement, the Issuer or its designee will have the right to make Benchmark Replacement Conforming Changes (as defined below) from time to time without the consent of the Holders.

Any determination, decision or election that may be made by the Issuer or its designee pursuant to these Benchmark Transition Provisions, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection (i) will be conclusive and binding on the Issuer, the Trustee, the paying agent, the Calculation Agent and any other agents and the Holders of the Securities absent manifest error, (ii) if made by the Issuer, will be made in the Issuer’s sole discretion, (iii) if made by the Issuer’s designee, will be made after consultation with the Issuer, and the designee will not make any such determination, decision or election to which the Issuer objects and (iv) notwithstanding anything to the contrary in the Indenture or the Securities, shall become effective without consent from the Holders of the Securities or any other party.

Any determination, decision or election pursuant to these Benchmark Transition Provisions not made by the Issuer’s designee will be made by the Issuer on the basis as described above. The designee shall have no liability for not making any such determination, decision or election. In addition, the Issuer may designate an entity (which may be its affiliate) to make any determination, decision or election that the Issuer has the right to make in connection with the Benchmark Transition Provisions set forth herein.

The Issuer will promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the Trustee, the paying agent, the Calculation Agent and the Holders of the Securities; provided that failure to give such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

For purposes of these Benchmark Transition Provisions:

“Benchmark” means, initially, Compounded Daily SOFR; provided that if the Issuer or its designee determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded Daily SOFR (including any daily published component used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement;

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Issuer or its designee as of the Benchmark Replacement Date:

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of “Interest Period,” changes to the timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, and other administrative matters) the Issuer or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Issuer or its designee decides that adoption of any portion of such market practice is not administratively feasible or if the Issuer or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Issuer or its designee determines is reasonably practicable);

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding Business Day adjustment) as the applicable tenor for the then-current Benchmark;

“designee” means a designee as selected and separately appointed by the Issuer in writing;

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor;

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark (including any daily published component used in the calculation thereof) for the applicable tenor excluding the applicable ISDA Fallback Adjustment;

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is the Compounded Daily SOFR, the SOFR Determination Time, or (2) if the Benchmark is not the Compounded Daily SOFR, the time determined by the Issuer or its designee after giving effect to the Benchmark Replacement Conforming Changes;

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto; and

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

All payments of principal and interest in respect of the Securities will be made by the Issuer without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax (“Taxes”) unless such withholding or deduction is required by law. In such event, the Issuer shall pay to a Holder such additional amounts (“Additional Amounts”) as will result in the receipt by the Holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any Securities under any of the following circumstances:

No Additional Amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where Securities are held through a participant of an international Clearing Organization or a financial intermediary (each, a “Participant”), in order to receive payments free of withholding or deduction by the Issuer for or on account of Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Japanese financial institution falling under certain categories prescribed by the Special Taxation Measures Act (a “Designated Financial Institution”), each such beneficial owner shall, at the time of entrusting a Participant with the custody of the relevant Securities, provide certain information prescribed by the Special Taxation Measures Act to enable the Participant to establish that such beneficial owner is exempted from the requirement for withholding or deduction of such Taxes (“Interest Recipient Information”), and advise the Participant if the beneficial owner ceases to be so exempted (including the case in which a beneficial owner who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of the Issuer).

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

By subscribing to the Securities as part of the distribution by the underwriters under the applicable underwriting agreement, an investor shall be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the Issuer or (ii) a Designated Financial Institution.

The Issuer shall make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. The Issuer shall use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge, and if certified copies are not available, the Issuer shall use reasonable efforts to obtain other evidence satisfactory to the Trustee, and the Trustee shall make such certified copies or other evidence available to the Holders upon reasonable request to the Trustee.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

The Issuer shall, as soon as practicable after the Prime Minister of Japan has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer or a Japanese court has publicly announced that it has granted permission to a transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, in accordance with Article 126-13 of the Deposit Insurance Act, deliver a written notice of such event to the Holders and beneficial owners of the Securities through DTC and to the Trustee. Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No service charge shall be made for any such registration of transfer or exchange; provided, however, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Sumitomo Mitsui Financial Group, Inc.

5.880% Senior Notes due 2026

This Security is one of a duly authorized issue of unsecured bonds, debentures, notes or other evidences of indebtedness of Sumitomo Mitsui Financial Group, Inc., a joint stock company (kabushiki kaisha) organized under the laws of Japan (herein called the “Issuer”, which term includes any successor person under the Indenture hereinafter referred) designated as its 5.880% Senior Notes due 2026 (herein called the “Securities”), issued under and pursuant to a senior indenture dated as of March 9, 2016, as supplemented by the First Supplemental Indenture dated as of July 16, 2019 (hereinafter called the “Indenture”), between the Issuer and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any paying agent, the Issuer and the Holders of the Securities and of the terms upon which the Securities are issued and are to be authenticated and delivered.

This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary as to denomination, date, amount, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. So long as any of the Securities are held in global form, payments of principal and interest on such Securities shall be made by wire transfer in immediately available funds in U.S. Dollars to a bank account in The City of New York designated by the Holder of this Registered Global Security. Otherwise, (i) the principal amount of the Securities will be payable by check, drawn on a bank in The City of New York, upon the presentation and surrender of the Securities at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose and (ii) interest on the Securities will be payable by check, drawn on a bank in The City of New York, mailed to the persons in whose names the Securities are registered as of the close of business on the record date which is at least five Business Days preceding the applicable Interest Payment Date (or the subsequent record date in the case of a defaulted interest payment) at the addresses of such persons as shall appear in the Security register of the Issuer; provided, however, that at the option of a Holder in whose name at least U.S.$1,000,000 principal amount of Securities are registered, all payments in respect of the Securities may be received by wire transfer in immediately available funds to a bank account in The City of New York designated by such Holder in a written notice received by the Trustee (a) in the case of an interest payment, prior to the record date which is at least five Business Days preceding the Interest Payment Date on which such payment is due and (b) in the case of payment of principal, prior to the record date which is at least five Business Days preceding the date of redemption or maturity, as the case may be; provided, however, that in the case of such a payment of principal, the Securities shall have been surrendered to the Trustee at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose for payment together with such notice.

All payments of principal and interest in respect of the Securities will be made by the Issuer without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax (“Taxes”) unless such withholding or deduction is required by law. In such event, the Issuer shall pay to a Holder such additional amounts (“Additional Amounts”) as will result in the receipt by the Holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any Securities under any of the following circumstances:

No Additional Amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where Securities are held through a participant of an international Clearing Organization or a financial intermediary (each, a “Participant”), in order to receive payments free of withholding or deduction by the Issuer for or on account of Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Japanese financial institution falling under certain categories prescribed by the Special Taxation Measures Act (a “Designated Financial Institution”), each such beneficial owner shall, at the time of entrusting a Participant with the custody of the relevant Securities, provide certain information prescribed by the Special Taxation Measures Act to enable the Participant to establish that such beneficial owner is exempted from the requirement for withholding or deduction of such Taxes (“Interest Recipient Information”), and advise the Participant if the beneficial owner ceases to be so exempted (including the case in which a beneficial owner who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of the Issuer).

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

By subscribing to the Securities as part of the distribution by the underwriters under the applicable underwriting agreement, an investor shall be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the Issuer or (ii) a Designated Financial Institution.

The Issuer shall make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. The Issuer shall use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge, and if certified copies are not available, the Issuer shall use reasonable efforts to obtain other evidence satisfactory to the Trustee, and the Trustee shall make such certified copies or other evidence available to the Holders upon reasonable request to the Trustee.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

The Issuer shall, as soon as practicable after the Prime Minister of Japan has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer or a Japanese court has publicly announced that it has granted permission to a transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, in accordance with Article 126-13 of the Deposit Insurance Act, deliver a written notice of such event to the Holders and beneficial owners of the Securities through DTC and to the Trustee. Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The security registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange; provided, however, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name this Security is registered upon the Security register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer nor the Trustee nor any such agent shall be affected by notice to the contrary.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, as herein prescribed.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Security is registered as of the close of business on the fifteenth day before the Interest Payment Date (whether or not a Business Day).

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any payment is due on the Securities on a day that is not a Business Day, payment will be made on the day that is the next succeeding Business Day without any additional interest as a result of such delay. Payments postponed to the next Business Day in this situation will be treated under the Indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the Securities or the Indenture, and no interest will accrue on the postponed amount from the original due date to the next succeeding day that is a Business Day.

The principal of, and interest and Additional Amounts on, the Securities will be payable in U.S. dollars. The Issuer will cause the Trustee, or the paying agent, if any, to pay such amounts, on the dates payment is to be made, directly to The Depository Trust Company (“DTC”).

The Issuer will pay the Holder hereof Additional Amounts with respect to withholding taxes as are provided for, and subject to the conditions stated, on the reverse of this Security.

This Security is being deposited with DTC acting as depository, and registered in the name of Cede & Co., a nominee of DTC.

Payments of principal and interest, including any Additional Amounts, on this Security shall be made in the manner specified on the reverse hereof and, to the extent not inconsistent with the provisions set forth herein, in the Indenture referred herein.

The Securities are not redeemable prior to maturity, except as set forth on the reverse of this Security and will not be subject to any sinking fund.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

This Security is one of a duly authorized issue of unsecured bonds, debentures, notes or other evidences of indebtedness of Sumitomo Mitsui Financial Group, Inc., a joint stock company (kabushiki kaisha) organized under the laws of Japan (herein called the “Issuer”, which term includes any successor person under the Indenture hereinafter referred) designated as its 5.800% Senior Notes due 2028 (herein called the “Securities”), issued under and pursuant to a senior indenture dated as of March 9, 2016, as supplemented by the First Supplemental Indenture dated as of July 16, 2019 (hereinafter called the “Indenture”), between the Issuer and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any paying agent, the Issuer and the Holders of the Securities and of the terms upon which the Securities are issued and are to be authenticated and delivered.

This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary as to denomination, date, amount, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. So long as any of the Securities are held in global form, payments of principal and interest on such Securities shall be made by wire transfer in immediately available funds in U.S. Dollars to a bank account in The City of New York designated by the Holder of this Registered Global Security. Otherwise, (i) the principal amount of the Securities will be payable by check, drawn on a bank in The City of New York, upon the presentation and surrender of the Securities at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose and (ii) interest on the Securities will be payable by check, drawn on a bank in The City of New York, mailed to the persons in whose names the Securities are registered as of the close of business on the record date which is at least five Business Days preceding the applicable Interest Payment Date (or the subsequent record date in the case of a defaulted interest payment) at the addresses of such persons as shall appear in the Security register of the Issuer; provided, however, that at the option of a Holder in whose name at least U.S.$1,000,000 principal amount of Securities are registered, all payments in respect of the Securities may be received by wire transfer in immediately available funds to a bank account in The City of New York designated by such Holder in a written notice received by the Trustee (a) in the case of an interest payment, prior to the record date which is at least five Business Days preceding the Interest Payment Date on which such payment is due and (b) in the case of payment of principal, prior to the record date which is at least five Business Days preceding the date of redemption or maturity, as the case may be; provided, however, that in the case of such a payment of principal, the Securities shall have been surrendered to the Trustee at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose for payment together with such notice.

All payments of principal and interest in respect of the Securities will be made by the Issuer without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax (“Taxes”) unless such withholding or deduction is required by law. In such event, the Issuer shall pay to a Holder such additional amounts (“Additional Amounts”) as will result in the receipt by the Holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any Securities under any of the following circumstances:

No Additional Amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where Securities are held through a participant of an international Clearing Organization or a financial intermediary (each, a “Participant”), in order to receive payments free of withholding or deduction by the Issuer for or on account of Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Japanese financial institution falling under certain categories prescribed by the Special Taxation Measures Act (a “Designated Financial Institution”), each such beneficial owner shall, at the time of entrusting a Participant with the custody of the relevant Securities, provide certain information prescribed by the Special Taxation Measures Act to enable the Participant to establish that such beneficial owner is exempted from the requirement for withholding or deduction of such Taxes (“Interest Recipient Information”), and advise the Participant if the beneficial owner ceases to be so exempted (including the case in which a beneficial owner who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of the Issuer).

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

By subscribing to the Securities as part of the distribution by the underwriters under the applicable underwriting agreement, an investor shall be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the Issuer or (ii) a Designated Financial Institution.

The Issuer shall make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. The Issuer shall use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge, and if certified copies are not available, the Issuer shall use reasonable efforts to obtain other evidence satisfactory to the Trustee, and the Trustee shall make such certified copies or other evidence available to the Holders upon reasonable request to the Trustee.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

The Issuer shall, as soon as practicable after the Prime Minister of Japan has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer or a Japanese court has publicly announced that it has granted permission to a transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, in accordance with Article 126-13 of the Deposit Insurance Act, deliver a written notice of such event to the Holders and beneficial owners of the Securities through DTC and to the Trustee. Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The security registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange; provided, however, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name this Security is registered upon the Security register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer nor the Trustee nor any such agent shall be affected by notice to the contrary.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, as herein prescribed.

This Security is governed by and shall be construed in accordance with the laws of the State of New York.

All capitalized terms used and not defined herein shall have the meanings assigned to them in the Indenture.

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

By subscribing to the Securities as part of the distribution by the underwriters under the applicable underwriting agreement, an investor shall be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the Issuer or (ii) a Designated Financial Institution.

The Issuer shall make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. The Issuer shall use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge, and if certified copies are not available, the Issuer shall use reasonable efforts to obtain other evidence satisfactory to the Trustee, and the Trustee shall make such certified copies or other evidence available to the Holders upon reasonable request to the Trustee.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

The Issuer shall, as soon as practicable after the Prime Minister of Japan has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer or a Japanese court has publicly announced that it has granted permission to a transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, in accordance with Article 126-13 of the Deposit Insurance Act, deliver a written notice of such event to the Holders and beneficial owners of the Securities through DTC and to the Trustee. Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The security registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange; provided, however, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name this Security is registered upon the Security register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer nor the Trustee nor any such agent shall be affected by notice to the contrary.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, as herein prescribed.

This Security is governed by and shall be construed in accordance with the laws of the State of New York.

This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary as to denomination, date, amount, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

Otherwise, (i) the principal amount of the Securities will be payable by check, drawn on a bank in The City of New York, upon the presentation and surrender of the Securities at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose and (ii) interest on the Securities will be payable by check, drawn on a bank in The City of New York, mailed to the persons in whose names the Securities are registered as of the close of business on the record date which is at least five Business Days preceding the applicable Interest Payment Date (or the subsequent record date in the case of a defaulted interest payment) at the addresses of such persons as shall appear in the Security register of the Issuer; provided, however, that at the option of a Holder in whose name at least U.S.$1,000,000 principal amount of Securities are registered, all payments in respect of the Securities may be received by wire transfer in immediately available funds to a bank account in The City of New York designated by such Holder in a written notice received by the Trustee (a) in the case of an interest payment, prior to the record date which is at least five Business Days preceding the Interest Payment Date on which such payment is due and (b) in the case of payment of principal, prior to the record date which is at least five Business Days preceding the date of redemption or maturity, as the case may be; provided, however, that in the case of such a payment of principal, the Securities shall have been surrendered to the Trustee at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose for payment together with such notice.

All payments of principal and interest in respect of the Securities will be made by the Issuer without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax (“Taxes”) unless such withholding or deduction is required by law. In such event, the Issuer shall pay to a Holder such additional amounts (“Additional Amounts”) as will result in the receipt by the Holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any Securities under any of the following circumstances:

No Additional Amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The security registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class).

Sumitomo Mitsui Financial Group, Inc., a joint stock company with limited liability organized under the laws of Japan (the “Company”), has filed with the U.S. Securities and Exchange Commission a Registration Statement on Form F-3 (File No. 333-261754) and the post-effective amendment no. 1 thereto (together, the “Registration Statement”) and the related Prospectus (the “Prospectus”) for the purpose of registering under the U.S. Securities Act of 1933, as amended (the “Securities Act”), certain securities, including U.S.$400,000,000 aggregate principal amount of the Company’s Senior Floating Rate Notes due 2026, U.S.$850,000,000 aggregate principal amount of the Company’s 5.880% Senior Notes due 2026, U.S.$750,000,000 aggregate principal amount of the Company’s 5.800% Senior Notes due 2028, U.S.$650,000,000 aggregate principal amount of the Company’s 5.852% Senior Notes due 2030 and U.S.$650,000,000 aggregate principal amount of the Company’s 5.776% Senior Notes due 2033 (the “Securities”). The Securities are to be issued pursuant to the provisions of the Senior Indenture dated as of March 9, 2016, as supplemented by the First Supplemental Indenture dated as of July 16, 2019 (the “Indenture”) between the Company and The Bank of New York Mellon, as trustee. The Securities are to be sold pursuant to the Underwriting Agreement dated July 6, 2023 (the “Underwriting Agreement”) among the Company and the several underwriters named therein (the “Underwriters”).

We, as your counsel, have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

In rendering the opinions expressed herein, we have, without independent inquiry or investigation, assumed that (i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all signatures on all documents that we reviewed are genuine, (iv) all natural persons executing documents had and have the legal capacity to do so, (v) all statements in certificates of public officials and officers of the Company that we reviewed were and are accurate and (vi) all representations made by the Company as to matters of fact in the documents that we reviewed were and are accurate.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we advise you that, in our opinion, assuming the Securities have been duly executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, the Securities will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability and subject to possible judicial or regulatory actions giving effect to foreign governmental actions or foreign laws affecting creditors’ rights.

We hereby confirm that our opinion as to the material U.S. federal income tax consequences to U.S. Holders of an investment in the Securities is set forth in full under the caption “Taxation—U.S. Federal Income Tax Considerations” in the Prospectus.

In connection with the opinion expressed above, we have assumed that the Company is validly existing as a joint stock company under the laws of Japan. In addition, we have assumed that the Indenture and the Securities (collectively, the “Documents”) are valid, binding and enforceable agreements of each party thereto, except to the extent expressly covered above with respect to the Company. We have also assumed that the execution, delivery and performance by each party to each Document to which it is a party (a) are within its corporate powers, (b) do not contravene, or constitute a default under, the articles of incorporation or bylaws or other constitutive documents of such party, (c) require no action by or in respect of, or filing with, any governmental body, agency or official and (d) do not contravene, or constitute a default under, any provision of applicable law or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon such party.

We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States, except that we express no opinion as to any law, rule or regulation that is applicable to the Company, the Documents or such transactions solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Documents or any of its affiliates due to the specific assets or business of such party or such affiliate. Insofar as the foregoing opinion involves matters governed by the laws of Japan, we have relied, without independent inquiry or investigation, on the opinion of Nagashima, Ohno and Tsunematsu to be filed as an exhibit to a report on Form 6-K to be filed by the Company on the date hereof.

We hereby consent to the filing of this opinion as an exhibit to a report on Form 6-K to be filed by the Company on the date hereof and its incorporation by reference into the Registration Statement and further consent to the reference to our name under the caption “Legal Matters” in the prospectus supplement which is a part of the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
