#### SUMMARY

#### What are ADB's Capital at Risk Notes?

Capital at Risk Notes are a type of debt securities that ADB may issue pursuant to the GMTN Program. However, an investment in Capital at Risk Notes entails significant risks that are different from those associated with an investment in a conventional debt security issued by ADB pursuant to its GMTN Program. *Capital at Risk Notes may result in the loss of your entire investment, with no payment of any type made to you at maturity*.

Each issue of Capital at Risk Notes will have different interest rates, interest payment dates and maturity dates, and may include provisions for early redemption. The terms of each Capital at Risk Note will be specified in the applicable Pricing Supplement.

#### What investment risks are involved?
The Capital at Risk Notes are designed to be highly speculative and sophisticated investments. Capital at Risk Notes contain one or more embedded derivatives that determine, in whole or in part, the interest amounts and the amount, if any, payable at maturity. The types of events or underliers to which the Capital at Risk Notes will be linked, however, may be significantly more complex than common types of structured notes offered to the public.

**Investors should have sufficient knowledge and experience in financial and business matters to evaluate the merits and risks of investing in a particular Capital at Risk Note, as well as access to, and knowledge of, appropriate analytical tools to evaluate such merits and risks, including underlier and derivative risk, in the context of their financial situation.**

You should consult the information set forth under the captions "Additional Risk Factors" beginning on page S-3 of this Supplement and "Risk Factors" beginning on page 12 of the accompanying Prospectus for a description of the risk factors involved in purchasing Capital at Risk Notes. In addition, the applicable Pricing Supplement of a particular issue of Capital at Risk Notes may include additional risk factors relating to such issue.

#### Are Capital at Risk Notes rated?
The ratings applicable to the GMTN Program will not apply to Capital at Risk Notes. Capital at Risk Notes may not be assigned any rating or, if rated, they may have a lower rating than the GMTN Program due to the risk of loss of principal. Whether or not a particular issue of Capital at Risk Notes has an assigned rating, investors should be aware that the terms of the Capital at Risk Notes will create a substantial risk. You may lose some or all of your investment regardless of any assigned rating. A rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency. In addition, you also will be subject to ADB's credit risk.

------

#### ADDITIONAL RISK FACTORS

*The following risk factors must be read together with the "Risk Factors" beginning on page 12 of the accompanying Prospectus. The following section does not describe all of the risks and investment considerations (including those relating to each investor's particular circumstances) of an investment in Capital at Risk Notes. Investors also should refer to and consider carefully the relevant Pricing Supplement for each particular issue of Capital at Risk Notes, which will describe additional risks and investment considerations associated with such Capital at Risk Notes. In addition, investors should consult their own financial and legal advisors as to the risks and investment considerations arising from an investment in an issue of Capital at Risk Notes and should possess the appropriate resources to analyze such investment and the suitability of such investment in their particular circumstances.*

#### Your investment may result in a loss
You cannot be assured that ADB will make any payment to you on the Capital at Risk Notes at maturity. The payment at maturity on the Capital at Risk Notes will depend on the features of the particular issue of Capital at Risk Notes as described in the applicable Pricing Supplement. Because of these features, the amount of cash you receive at maturity may be more or less than the amount you invested in the Capital at Risk Notes. Accordingly, you may lose some or all of your investment. There may not be a minimum amount that ADB will pay at maturity; *therefore, you may lose your entire investment in the Capital at Risk Notes*.

#### Your yield may be lower than the yield on a standard debt security of comparable maturity
The yield that you will receive on your Capital at Risk Notes, which could be negative, may be less than the return you could earn on other investments. Even if your yield is positive, your yield may be less than the yield you would earn if you bought a conventional senior debt security of ADB with the same maturity date. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money. Unlike conventional senior debt securities, you may not receive full repayment of principal at maturity.

#### At the time the terms of your Capital at Risk Notes are set, they may be worth less than the issue price
Capital at Risk Notes contain one or more embedded derivatives that determine, in whole or in part, the interest amounts and the amount, if any, payable at maturity. The estimated value of the Capital at Risk Notes at the time the terms of the Capital at Risk Notes are set on the trade date may be less than the issue price. This difference may be because of fees, costs, differences in derivatives pricing and other factors. The applicable Pricing Supplement for your Capital at Risk Notes will explain any such difference in issue price and estimated value and the reasons therefor if applicable to your Capital at Risk Notes.

#### There may not be an active trading market for the Capital at Risk Notes

Capital at Risk Notes may not be listed or displayed on any securities exchange or any electronic communications network. There can be no assurance that a liquid trading market will develop. Even if a secondary market for the Capital at Risk Notes were to develop, it may not provide significant liquidity and transaction costs in any secondary market could be high. As a result, the difference between bid and asked prices for Capital at Risk Notes in any secondary market could be substantial. If you sell your Capital at Risk Notes before maturity, you may have to do so at a discount from the initial issue price, and, as a result, you may suffer substantial losses.

------

***The Capital at Risk Notes will be obligations of ADB. No other company or entity will be responsible for payments under the Capital at Risk Notes***

The Capital at Risk Notes are to be issued by ADB. The Capital at Risk Notes will not be guaranteed by any other company or entity. No other entity or company will be responsible for payments under the Capital at Risk Notes or liable to holders of the Capital at Risk Notes in the event ADB defaults under the Capital at Risk Notes.

#### Any decline in value in ADB's credit ratings may affect the value of the Capital at Risk Notes

ADB's credit ratings are an assessment of its ability to pay its obligations, including those on the offered Capital at Risk Notes. Consequently, actual or anticipated declines in ADB's credit ratings may affect the value of the Capital at Risk Notes.

#### The regulation and reform of "benchmarks" may adversely affect the value of the Capital at Risk Notes linked to or referencing such "benchmarks"

Reference rates or indices (including interest rate benchmarks) which are used to determine the amounts payable under financial instruments or the value of such financial instruments ("**Benchmarks**") are the subject of national and international regulatory guidance and proposals for reform. Some of these reforms are already effective while others are still to be implemented. These reforms may cause a Benchmark to perform differently than it has done in the past, to be discontinued or to disappear, or have other consequences which cannot be predicted. Any such consequence could have a material adverse effect on the value or liquidity of, and the amount payable under, any Notes linked to, referencing, or otherwise dependent (in whole or in part) upon, a Benchmark.

Any of the international or national reforms, or the general increased regulatory scrutiny of Benchmarks, could increase the costs and risks of administering or otherwise participating in the setting of a Benchmark and complying with any such regulations or requirements. Such factors may have (without limitation) the following effects on certain Benchmarks: (i) discouraging market participants from continuing to administer or contribute to a Benchmark; (ii) triggering changes in the rules or methodologies used in a Benchmark; (iii) reducing, increasing or otherwise affecting the volatility or level of the relevant Benchmark; and/or (iv) leading to the disappearance of a Benchmark. Any of the above changes, or any other consequential changes as a result of international or national reforms or other initiatives or investigations, could have a material adverse effect on the value of and return on any Notes linked to, referencing, or otherwise dependent (in whole or in part) upon, a Benchmark.

Investors should be aware that, if a Benchmark were discontinued or otherwise unavailable, the rate of interest on the Capital at Risk Notes which are linked to or which reference such Benchmark will be determined for the relevant period by the fallback provisions applicable to such Capital at Risk Notes as set forth in the applicable Pricing Supplement. Such fallback provisions can be applied without consent of the holders of the Capital at Risk Notes and could have unexpected commercial consequences, and there can be no assurance that, due to the particular circumstances of each holder of the Capital at Risk Notes, any such determination will be favorable to each holder of the Capital at Risk Notes. Moreover, any of the above matters or any other significant change to the setting or existence of any relevant Benchmark could have a material adverse effect on the value or liquidity of, and the amount payable under, such Capital at Risk Notes.

The emergence of alternatives to a Benchmark may also cause such Benchmark to perform differently than in the past, or there could be other consequences which cannot be predicted, each of which could have a material adverse effect on the value of, and return on, any Capital at Risk Notes linked to or referencing such Benchmark. The development of alternatives to a Benchmark may result in Capital at Risk Notes linked to or referencing such Benchmark performing differently than would otherwise have been the case if the alternatives to such Benchmark had not developed.

------

Investors should consult their own independent advisors and make their own assessment about the potential risks imposed by the Benchmarks reforms in making any investment decision with respect to any Capital at Risk Notes linked to or referencing a Benchmark.

#### Change of law

The terms and conditions set forth in the accompanying Prospectus (the "**Conditions**" and each a "**Condition**"), subject to completion and amendment and as supplemented or varied in accordance with the provisions of the applicable Pricing Supplement, will apply to the Capital at Risk Notes referred to in such Pricing Supplement. The Conditions of the Capital at Risk Notes are based on English law or laws of the State of New York in effect as at the date of issue of the relevant Capital at Risk Notes. No assurance can be given as to the impact of any possible judicial decision or change to English law or laws of the State of New York or administrative practice after the date of issue of the relevant Capital at Risk Notes.

**PROSPECTUS SUPPLEMENT dated 23 April 2026**

### ASIAN DEVELOPMENT BANK

### U.S.$80,000,000

### Floating Rate Kyrgyz Republic Disaster Relief Capital at Risk Notes

### due 30 May 2029
This prospectus supplement (this "**Prospectus Supplement**") is issued to provide information with respect to the proposed issuance by Asian Development Bank ("**ADB**" or the "**Issuer**") of Floating Rate Kyrgyz Republic Disaster Relief Capital at Risk Notes due 30 May 2029 (the "**Notes**"). As described herein, if one or more Applicable Events occur with respect to the Notes, all or a portion of the Outstanding Nominal Amount of the Notes may be reduced by one or more Principal Reductions. Any such Principal Reduction would lead to a reduction (possibly to zero (U.S.$0)) in the interest (except with respect to days on or before 30 April 2027) and any Redemption Amount (if any) payable on the Notes.

This Prospectus Supplement supplements the terms and conditions in, and incorporates by reference, the accompanying Prospectus dated 9 December 2020, and all documents incorporated by reference therein, as supplemented by the Capital at Risk Notes Prospectus Supplement dated 1 April 2026, attached hereto (as so supplemented, the "**Prospectus**"), and should be read in conjunction with the Prospectus. Unless otherwise defined in this Prospectus Supplement, terms used herein have the same meaning as in the accompanying Prospectus. For a detailed description of the terms of the Notes, see Attachment A to this Prospectus Supplement.

The Notes relate to the perils of Earthquakes and Extreme Precipitation. An "Applicable Event" will be an Earthquake Event or an Extreme Precipitation Event, as the case may be.

Interest on the Notes will accrue on the Outstanding Nominal Amount of the Notes, except that the Risk Margin portion of interest will accrue on the Aggregate Nominal Amount of the Notes from and including the Issue Date, to and including 30 April 2027, and thereafter will accrue on the Outstanding Nominal Amount of the Notes (which may be zero (U.S.$0)). Interest will be payable in arrears on each Specified Interest Payment Date. In the case of a Mandatory Redemption Event, accrued interest will be paid on the applicable Redemption Amount Payment Date. Once the Notes are fully redeemed or paid, no further interest will be paid with respect to the Notes.

Application will be made to the Singapore Exchange Securities Trading Limited, also known as SGX-ST (the "**Singapore Stock Exchange**") for the listing and quotation of the Notes on the Official List of the Singapore Stock Exchange. The Singapore Stock Exchange assumes no responsibility for the correctness of any of the statements made, opinions expressed or reports contained in this Prospectus Supplement. Approval in-principle from the Singapore Stock Exchange, admission of the Notes to the Official List of the Singapore Stock Exchange and the listing and quotation of any Notes on, the Singapore Stock Exchange are not to be taken as an indication of the merits of ADB, the Global Medium-Term Note Program of ADB or the Notes. The Notes, if traded on the Singapore Stock Exchange, will be traded in a minimum board lot size of U.S.$250,000 (or its equivalent in foreign currencies) for so long as the Notes are listed on the Singapore Stock Exchange and the rules of the Singapore Stock Exchange so require.

**Notification pursuant to Section 309B(1) of the Securities and Futures Act 2001 of Singapore ("SFA**") – The Issuer has determined, and hereby notifies all Relevant Persons (as defined in Section 309A(1) of the SFA) that the Notes are prescribed capital markets products (as defined in the Securities and Futures (Capital Markets Products) Regulations of 2018 of Singapore) and Excluded Investment Products (as defined in MAS Notice SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on Recommendations on Investment Products).

*Investing in the Notes is speculative and involves a high degree of risk including the risk of a total loss of principal amount of the Notes. See "Additional Risk Factors" beginning on page PS-28 of this Prospectus Supplement, "Risk Factors" beginning on page 12 of the Prospectus dated December 9, 2020 and "Additional Risk Factors" beginning on page S-3 of the Capital at Risk Notes Prospectus Supplement dated 1 April 2026 for a discussion of certain factors to be considered in connection with an investment in the Notes.*

*THE NOTES ARE EXEMPTED SECURITIES UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "**SECURITIES ACT**"), AND THEREFORE THE NOTES HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE SECURITIES ACT OR ANY STATE OR FOREIGN SECURITIES LAWS.

The date of this Prospectus Supplement is 23 April 2026.

------

The rate of interest applicable to the Notes for each day will be a per annum rate equal to Compounded SOFR for the applicable Interest Period (determined as described below) *plus* the Funding Margin *plus* the Risk Margin, subject to a minimum per annum rate equal to the Risk Margin. See "*Overview—The Notes—Interest—Amounts of interest*" and "*Overview—The Notes—Interest—Rate of interest*".

For each Interest Period, accrued interest on the Notes will be calculated as the *sum* of the Daily Interest Amounts for each day in such Interest Period, using a "**Calculation Amount**" of U.S.$1,000 nominal amount of the Notes.

The "**Daily Interest Amount**" for each Calculation Amount for the Notes shall equal:

<br> (a) for each day from and including the Issue Date to and including 30 April 2027, one three hundred sixtieth (1/360) *times* the *sum* of (A) and (B):

(A) the greater of (x) the fraction the numerator of which is the Outstanding Nominal Amount of the Notes as of the first day of such Interest Period (after giving effect to any Principal Reduction on such date) and the denominator of which is the Aggregate Nominal Amount of the Notes times U.S.$1,000 times the *sum* of (i) Compounded SOFR for such Interest Period and (ii) the Funding Margin and (y) zero (0), and

(B) the applicable Risk Margin on such day times U.S.$1,000; and

<br> (b) for each day after 30 April 2027 to but excluding the Maturity Date, one three hundred sixtieth (1/360) times the *sum* of (A) and (B):

(A) the greater of (x) the fraction the numerator of which is the Outstanding Nominal Amount of the Notes as of the first day of such Interest Period (after giving effect to any Principal Reduction and/or Partial Repayment on such date) and the denominator of which is the Aggregate Nominal Amount of the Notes times U.S.$1,000 times the *sum* of (i) Compounded SOFR for such Interest Period and (ii) the Funding Margin and (y) zero (0); and

(B) the applicable Risk Margin on such day times the fraction the numerator of which is the Outstanding Nominal Amount of the Notes as of the first day of the Interest Period (after giving effect to any Principal Reduction and/or Partial Repayment on such date) and the denominator of which is the Aggregate Nominal Amount of the Notes times U.S.$1,000.

If the Outstanding Nominal Amount of the Notes is reduced to zero (U.S.$0) on any Principal Reduction Date prior to the Specified Interest Payment Date scheduled to occur on 30 April 2027, ADB must pay the Residual Interest Amount for the Notes on such Principal Reduction Date in addition to the payment of accrued interest with respect to the Interest Period ending on such Principal Reduction Date, and no further interest will be paid with respect to the Notes.

An Extension Event may occur with respect to the Notes, pursuant to which the maturity of the Notes would be extended. If a Partial Extension Notice is provided, the Outstanding Nominal Amount of the Notes would be redeemed in part, on the Scheduled Maturity Date or the relevant Extended Maturity Date at a price equal to 100% of the Outstanding Nominal Amount of the Notes to be partially redeemed (together with accrued interest, if any). See "*Overview—The Notes—Maturity and Extension; Redemption Terms*".

The net proceeds from the sale of the Notes will be used as described under "*Use of Proceeds*".

ADB will enter into a Risk Transfer Agreement with the Country (as defined under "*Overview—Offering of the Notes*" below) with respect to the Notes. If a Principal Reduction occurs with respect to the Notes, ADB will be obligated to pay to the Country, pursuant to the Risk Transfer Agreement, an amount equal to such Principal Reduction.

#### GEM DISCLAIMERS
FONDAZIONE GEM ("**GEM**") HAS PERFORMED, AND WILL PERFORM, CERTAIN STATISTICAL MODELING AND OTHER SERVICES, AS DESCRIBED IN THIS PROSPECTUS SUPPLEMENT, INCLUDING AS THE MODELING AGENT FOR THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT.

THE STATISTICAL DATA, MODELING AND EXPLANATIONS INCLUDED HEREIN UNDER THE SECTION "*ADDITIONAL RISK FACTORS*" AND UNDER THE SECTIONS "*EARTHQUAKE EXPERT RISK ANALYSIS*", "*EARTHQUAKE EXPERT RISK ANALYSIS RESULTS*" AND "*EARTHQUAKE DATA FILE*" (WHICH INCLUDES INFORMATION MADE AVAILABLE ON THE SITE) (THE "**EARTHQUAKE DATA FILE**") IN APPENDIX E-I, APPENDIX E-II AND APPENDIX E-III, RESPECTIVELY, ATTACHED HERETO (JOINTLY REFERRED TO HEREIN AS THE "**EARTHQUAKE EXPERT RISK ANALYSIS REPORT**") HAVE BEEN PREPARED BY GEM AS AN EXPERT IN STATISTICAL MODELING AND THE ANALYSIS OF RISKS ASSOCIATED WITH EARTHQUAKES. INVESTORS IN THE NOTES ARE ADVISED THAT THE RISK ANALYSIS RESULTS REPORTED BY GEM ARE BASED ON GEM EARTHQUAKE MODEL FOR CENTRAL ASIA V2025.0 (THE "**GEM MODEL**"). THE RISK ANALYSIS RESULTS REPORTED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT ARE, THEREFORE, SUBJECT TO NUMEROUS ASSUMPTIONS, UNCERTAINTIES AND THE INHERENT LIMITATIONS OF ANY STATISTICAL ANALYSIS, AS MORE FULLY DESCRIBED HEREIN. ACTUAL LOSS EXPERIENCE IS INHERENTLY UNPREDICTABLE. INVESTORS ARE URGED TO READ CAREFULLY THE MATERIAL CONTAINED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT AND UNDER THE CAPTION "*ADDITIONAL RISK FACTORS*" FOR A DESCRIPTION OF SUCH ASSUMPTIONS, UNCERTAINTIES AND LIMITATIONS.

THE DATA AND METHODOLOGY DESCRIBED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, AND THE ANALYSES, ESTIMATES AND SERVICES DESCRIBED THEREIN, ARE PROVIDED "AS IS" WITHOUT WARRANTY OR GUARANTY OF ANY KIND TO THE INVESTORS IN THE NOTES. THESE ANALYSES AND ESTIMATES ARE PROVIDED FOR ILLUSTRATIVE PURPOSES ONLY AND ARE NOT INTENDED TO PROVIDE, NOR SHOULD THEY BE INTERPRETED AS PROVIDING, ANY FACTS REGARDING, OR ANY GUARANTY OR PREDICTION OR FORECAST OF, THE LIKELIHOOD THAT INVESTORS IN THE NOTES WILL RECEIVE PAYMENT THEREON. NOTWITHSTANDING THE ANALYSES, ESTIMATES AND ASSUMPTIONS SET FORTH IN THIS PROSPECTUS SUPPLEMENT AND IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, ONE OR MORE APPLICABLE EVENTS COULD OCCUR AT ANY TIME DURING THE RISK PERIOD OF THE NOTES. ANY EARTHQUAKE EVENT WOULD RESULT IN A REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF THE NOTES UP TO THE EXTENT OF THE EARTHQUAKE SUBLIMIT, AND IN A CORRESPONDING REDUCTION IN THE INTEREST ON, THE NOTES. ANY EARTHQUAKE EVENT MAY HAVE CHARACTERISTICS SIMILAR TO OR DIFFERENT FROM THOSE OF SIMULATED EVENTS THAT DID NOT QUALIFY AS APPLICABLE EVENTS IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, OR CHARACTERISTICS NOT CONSIDERED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT.

GEM DOES NOT REPRESENT INVESTORS IN THE NOTES OR THEIR INTERESTS IN ANY WAY. GEM DOES NOT SPONSOR, ENDORSE, OFFER, SELL, OR PROMOTE THE NOTES, NOR DOES IT MAKE ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, TO ANY PERSON, REGARDING THE ADVISABILITY OF INVESTING IN THE NOTES OR THE LEGALITY OF AN INVESTMENT IN THE NOTES. GEM IS NOT RESPONSIBLE FOR THE DETERMINATION OF THE STRUCTURE OR THE PRICING OF THE NOTES. FURTHERMORE, GEM HAS NO OBLIGATION OR LIABILITY IN CONNECTION WITH THE ADMINISTRATION, MARKETING, OR TRADING, IF ANY, OF THE NOTES OR LIABILITY FOR ANY ADVERSE FINANCIAL RESULT OR ANY DIRECT, INDIRECT, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES WHATSOEVER. GEM ASSUMES NO RESPONSIBILITY FOR THE CONTENT OF ANY AGREEMENTS TO WHICH IT IS NOT A SIGNATORY, AND IN PARTICULAR (BUT NOT BY WAY OF LIMITATION) HAS NO RESPONSIBILITY FOR ENSURING THAT THE PROCEDURES AND PROVISIONS OF ANY SUCH AGREEMENTS ARE CONSISTENT WITH THIS PROSPECTUS SUPPLEMENT OR WITH ANY OTHER AGREEMENT EXECUTED IN CONNECTION WITH THE NOTES.

vi

------

IN THE DEVELOPMENT OF THE GEM MODEL, GEM HAS RELIED ON PUBLISHED TECHNICAL PAPERS AND STUDIES, CATALOGS AND OTHER DATA SOURCES RELEVANT TO EARTHQUAKES, AND HAS SELECTED THOSE THAT IT BELIEVES TO REPRESENT CREDIBLE SCIENTIFIC OPINION RELATED TO EARTHQUAKES. HOWEVER, SINCE NO SCIENTIFIC CONSENSUS ON MODELS OR RISK PARAMETERS EXISTS, GEM ACKNOWLEDGES (AND INVESTORS IN THE NOTES ARE DEEMED TO ACKNOWLEDGE) THAT OTHER CREDIBLE, PUBLISHED MODELS AND/OR RISK PARAMETERS MAY EXIST THAT, IF USED, COULD PRODUCE MATERIALLY DIFFERENT RESULTS. THE GEM MODEL DOES NOT PREDICT THE PROBABILISTIC OCCURRENCE OF ANY CATASTROPHIC EVENTS. GEM HAS NOT VERIFIED THE AUTHENTICITY OR ACCURACY OF THE ORIGINAL DATA IN THE HISTORICAL CATALOGS OR OTHER DATA SOURCES USED TO DEVELOP THE GEM MODEL. PRIOR TO INVESTING IN THE NOTES, INVESTORS SHOULD CONSULT THEIR OWN EXPERT ADVISORS WHOSE CONCLUSIONS MAY DIFFER FROM THOSE OF GEM.

NO MODEL OF CATASTROPHIC EVENTS IS, OR COULD BE, AN EXACT REPRESENTATION OF REALITY. THE GEM MODEL RELIES ON VARIOUS METHODOLOGIES AND ASSUMPTIONS (INCLUDING ASSUMPTIONS ABOUT THE AUTHENTICITY, ACCURACY AND COMPLETENESS OF HISTORICAL DATA), SOME OF WHICH ARE SUBJECTIVE AND SUBJECT TO UNCERTAINTY, AND WHICH MIGHT NOT BE USED IN MODELS PRODUCED BY OTHER MODELING FIRMS. FURTHERMORE, THERE MAY BE MATERIAL DIFFERENCES IN THE WAY IN WHICH THESE ELEMENTS ARE CONSIDERED BY OTHER MODELING FIRMS. CONSEQUENTLY, THERE CAN BE NO ASSURANCE THAT THE GEM MODEL REPRESENTS AN ACCURATE ESTIMATION OF THE RISK OF LOSS OR ANY REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF, AND INTEREST ON, THE NOTES. ACCORDINGLY, THE EXPECTED LOSS ESTIMATES AND RELATED PROBABILITIES PRODUCED BY THE GEM MODEL ARE THEMSELVES SUBJECT TO UNCERTAINTY. GEM REVIEWS MODEL ASSUMPTIONS FROM TIME TO TIME IN VIEW OF NEW DATA AND OTHER INFORMATION TO REFINE AND MODIFY ITS MODELS AS SUCH INFORMATION BECOMES AVAILABLE. AS SUCH, THE GEM MODEL MAY NOT NECESSARILY REFLECT THE MOST CURRENT SCIENTIFIC RESEARCH OR THE MOST CURRENT MODELS OF GEM AT ANY TIME. ESTIMATES GENERATED BY SUCH REFINED OR MODIFIED MODELS MAY MATERIALLY DIFFER FROM THE ESTIMATES GENERATED BY THE GEM MODEL IN CONNECTION WITH THE NOTES, AND THE USE OF SUCH MODELS IN LIEU OF THE GEM MODEL MIGHT SIMILARLY MATERIALLY ALTER THE INFORMATION PROVIDED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT.

THE RESULTS OF GEM'S ANALYSIS SHOULD NOT BE VIEWED AS FACTS OR FORECASTS OF FUTURE EVENTS, OR OF ANY REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF, AND INTEREST ON, THE NOTES, AND SHOULD NOT BE RELIED UPON AS A REPRESENTATION OF THE CURRENT OR FUTURE VALUE OF THE NOTES. THERE IS CONSIDERABLE UNCERTAINTY REGARDING THE ASSUMPTIONS AND PARAMETERS USED IN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, ARISING FROM INSUFFICIENT DATA, LIMITED SCIENTIFIC KNOWLEDGE AND ALTERNATIVE EMPIRICAL RELATIONSHIPS, AS WELL AS FROM THE RANDOM NATURE OF EARTHQUAKES. THE GEM MODEL CANNOT INCORPORATE ALL SOURCES OF UNCERTAINTY. FURTHERMORE, THE ASSUMPTIONS AND METHODOLOGIES USED BY GEM DO NOT CONSTITUTE THE EXCLUSIVE SET OF REASONABLE ASSUMPTIONS AND MAY NOT BE CORRECT. USE OF ALTERNATIVE ASSUMPTIONS AND/OR MODELS COULD YIELD RESULTS MATERIALLY DIFFERENT FROM THOSE PRODUCED BY GEM. GEM ALSO DID NOT ELICIT FROM OTHER EXPERTS ALTERNATIVE INTERPRETATIONS OF ITS DATA OR METHODS, NOR DID GEM RESEARCH ALL POTENTIALLY AVAILABLE INTERPRETATIONS OF SUCH DATA AND METHODS ON THE BASIS THAT GEM CONSIDERED ITS OWN INTERPRETATIONS TO BE MORE RELIABLE. THE MODELED PRINCIPAL REDUCTION AND RELATED PROBABILITIES GENERATED BY THE GEM MODEL ARE NOT NECESSARILY PREDICTIVE OF FUTURE EARTHQUAKES. INVESTORS IN THE NOTES SHOULD NOT VIEW THE EXPECTED LOSS ESTIMATES AND RELATED PROBABILITIES GENERATED BY THE GEM MODEL AS PREDICTING THE LIKELIHOOD OF THE OCCURRENCE DURING THE RISK PERIOD OF THE NOTES OF ONE OR MORE EARTHQUAKE EVENTS RESULTING IN A REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF, AND INTEREST ON, THE NOTES. GEM HAS NOT MADE ANY EFFORT, NOR DOES IT HAVE THE ABILITY, TO PREDICT APPLICABLE EVENTS AFFECTING THE NOTES. ACCORDINGLY, THE ACTUAL FREQUENCY AND SEVERITY OF EARTHQUAKE EVENTS COULD DIFFER MATERIALLY FROM THE FREQUENCY AND SEVERITY ESTIMATED BY GEM.

THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT IS INCLUDED HEREIN AND MADE AVAILABLE TO INVESTORS IN RELIANCE UPON GEM AS AN EXPERT IN SUCH MATTERS. SEE "*EXPERTS*." THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT IS, AS NOTED ABOVE, BASED ON CERTAIN ASSUMPTIONS, JUDGMENTS, AND METHODOLOGIES OF GEM, A NUMBER OF WHICH ARE CONFIDENTIAL AND PROPRIETARY TO GEM.

vii

------

AS A RESULT OF ITS ONGOING PROCESS OF INTERNAL REVIEW, GEM MAY REFINE ITS MODEL ASSUMPTIONS FROM TIME TO TIME IN LIGHT OF NEW SCIENTIFIC AND OTHER INFORMATION AS SUCH INFORMATION BECOMES AVAILABLE. SUCH REFINEMENTS MAY MATERIALLY ALTER, AND HAVE IN THE PAST MATERIALLY ALTERED, THE LOSS ESTIMATES GENERATED BY THE MODEL. FURTHERMORE, TO THE EXTENT THAT GEM BECOMES AWARE OF ISSUES EITHER IN ITS MODELS OR IN THE SOFTWARE EXPRESSION OF SUCH MODELS WHICH MAY AFFECT THEIR OUTPUT IN UNINTENDED WAYS, IT MAY, DEPENDING ON THE MATERIALITY OF THE ISSUES, COMMUNICATE SUCH ISSUES TO ITS LICENSEES AND RESOLVE THEM IN SUBSEQUENT VERSIONS OF ITS MODELS. AS SUCH THE GEM MODEL MAY NOT NECESSARILY REFLECT THE MOST CURRENT MODELS OF GEM AT ANY TIME.

NONE OF ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE EARTHQUAKE EVENT CALCULATION AGENT, THE COUNTRY OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES, OR ANY OF THEIR RESPECTIVE DIRECTORS OR OFFICERS, HAS REVIEWED, OR MAKES, OR SHALL BE DEEMED TO MAKE, ANY REPRESENTATION WITH RESPECT TO THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, INCLUDING (WITHOUT LIMITATION) THE ADEQUACY, COMPLETENESS, APPROPRIATENESS OR OTHERWISE OF THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT.

WITHOUT INTENDING TO LIMIT THE FOREGOING, IN PARTICULAR, NONE OF ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE EARTHQUAKE EVENT CALCULATION AGENT, THE COUNTRY OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES, OR ANY OF THEIR DIRECTORS OR OFFICERS, HAS REVIEWED THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT TO DETERMINE (I) THE REASONABLENESS OF THE ASSUMPTIONS, JUDGMENTS AND METHODOLOGIES UTILIZED BY GEM, (II) WHETHER SUCH ASSUMPTIONS, JUDGMENTS AND METHODOLOGIES SHOULD BE SUPPLEMENTED IN ANY WAY THROUGH THE USE OF ALTERNATIVE ASSUMPTIONS, JUDGMENTS OR METHODOLOGIES, (III) WHETHER THE ASSUMPTIONS, JUDGMENTS AND METHODOLOGIES UTILIZED BY GEM INCLUDE THE APPROPRIATE FACTORS THAT COULD CONTRIBUTE TO A REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF, AND INTEREST ON, THE NOTES AND (IV) WHETHER THE USE OF ALTERNATIVE ASSUMPTIONS, JUDGMENTS AND METHODOLOGIES, OR THE USE OF DIFFERENT CATASTROPHE SIMULATION MODELS, COULD YIELD RESULTS MATERIALLY DIFFERENT FROM THOSE GENERATED BY THE GEM MODEL. THE ACTUAL PRINCIPAL REDUCTION WITH RESPECT TO ANY EARTHQUAKE EVENT, IF ANY, WILL LIKELY DIFFER FROM THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, POSSIBLY MATERIALLY.

BECAUSE OF THE INHERENT LIMITATION OF RELYING ON THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT FOR LOSS ESTIMATION, AND BECAUSE OF THE SUBJECTIVE NATURE OF MANY OF GEM'S ASSUMPTIONS, JUDGMENTS AND METHODOLOGIES IN PREPARING THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT, EACH OF ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE EARTHQUAKE EVENT CALCULATION AGENT, THE COUNTRY AND EACH OF THEIR RESPECTIVE AFFILIATES AND REPRESENTATIVES EXPRESSLY DISCLAIMS ANY RESPONSIBILITY FOR, OR ANY LIABILITY BASED UPON, A FINDING THAT THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT INCLUDES ANY UNTRUE STATEMENT OF A MATERIAL FACT OR THAT THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT OMITS TO STATE A MATERIAL FACT NECESSARY IN ORDER TO MAKE THE STATEMENTS, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH THEY WERE MADE, NOT MISLEADING.

GEM PROVIDES SERVICES TO ADB, THE INITIAL PURCHASER, THE EVENT CALCULATION AGENT, THE COUNTRY AND THEIR RESPECTIVE AFFILIATES IN RESPECT OF THE PROPOSED OFFERING AND MAY PROVIDE SUCH TYPE OF SERVICES AND MAY ENGAGE IN OTHER TYPES OF BUSINESS WITH ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE EVENT CALCULATION AGENT, THE COUNTRY OR ANY OF THEIR RESPECTIVE AFFILIATES IN THE FUTURE. IN ADDITION, ADB HAS AGREED UNDER ITS ENGAGEMENT LETTER WITH GEM (THE "**GEM ENGAGEMENT LETTER**") TO INDEMNIFY GEM IN RESPECT OF CERTAIN CLAIMS, LOSSES AND EXPENSES ARISING FROM OR RELATING TO THE SERVICES PROVIDED BY GEM UNDER THE GEM ENGAGEMENT LETTER.

GEM HAS PROVIDED ITS ANALYSES, EXPECTED LOSS ESTIMATES AND RELATED PROBABILITIES AS CONTAINED WITHIN THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT. INVESTORS IN THE NOTES WILL HAVE NO RIGHT TO ENFORCE OR TAKE ACTIONS AGAINST GEM OR ANY RIGHT UNDER THE GEM ENGAGEMENT LETTER OR IN CONNECTION THEREWITH. ADB'S USE OF THE INFORMATION PROVIDED BY GEM, PARTICULARLY WITH REGARD TO ANY DISCLOSURE MADE IN OR OMITTED FROM THIS PROSPECTUS SUPPLEMENT, IS COMPLETELY WITHIN ADB'S SOLE DISCRETION, AND NOT THE RESPONSIBILITY OF GEM.

#### AIR DISCLAIMERS
THE EARTHQUAKE PAYOUT AMOUNT WITH RESPECT TO AN EARTHQUAKE EVENT WILL BE CALCULATED AND DETERMINED BASED UPON THE EARTHQUAKE EVENT PARAMETERS PROVIDED BY THE APPLICABLE EARTHQUAKE REPORTING AGENCY. ANY EARTHQUAKE REPORTING AGENCY MAY MAKE AVAILABLE FROM TIME TO TIME SEVERAL DIFFERENT REPORTS WHICH MAY SHOW DIFFERENT LEVELS OF ACCURACY AND PRECISION AND VARYING PARAMETERS. THE EARTHQUAKE EVENT PARAMETERS AS REPORTED BY THE APPLICABLE EARTHQUAKE REPORTING AGENCY WILL BE USED BY THE EARTHQUAKE EVENT CALCULATION AGENT WHO WILL BE UNDER NO OBLIGATION TO UNDERTAKE ANY INDEPENDENT ASSESSMENT OF THE ACCURACY OF THE PARAMETERS SO REPORTED.

THE PROCEDURES TO BE PERFORMED BY AIR IN ITS CAPACITY AS EARTHQUAKE EVENT CALCULATION AGENT WILL RESULT IN A FACTUAL DETERMINATION AS TO WHETHER AN EARTHQUAKE EVENT HAS OCCURRED OR THE EXTENT THEREOF. THE DETERMINATION WILL BE PERFORMED IN ACCORDANCE WITH THE METHODOLOGIES DESCRIBED IN THIS PROSPECTUS SUPPLEMENT AND AS SPECIFIED IN THE EARTHQUAKE EVENT CALCULATION AGENT AGREEMENT (AS THAT TERM IS DEFINED ELSEWHERE IN THIS PROSPECTUS SUPPLEMENT). THE TERMS OF THE NOTES PROVIDE THAT ALL DETERMINATIONS MADE BY AIR, AS THE EARTHQUAKE EVENT CALCULATION AGENT, IN AN EVENT REPORT ARE FINAL AND BINDING, ABSENT MANIFEST ERROR THAT IS IDENTIFIED IN A WRITTEN NOTICE RECEIVED BY ADB PRIOR TO THE DATE WHICH IS THREE (3) BUSINESS DAYS FOLLOWING THE DATE ON WHICH SUCH EVENT REPORT IS FIRST MADE AVAILABLE ON THE SITE (AS DEFINED UNDER THE HEADING "*AVAILABLE INFORMATION*"). NO SEPARATE REVIEW OR APPRAISAL OF THE ACCURACY OF THE DEFINED METHODOLOGIES OR DATA USED WILL BE PERFORMED. INVESTORS ARE ADVISED THAT THE CALCULATION OF EARTHQUAKE PAYOUT AMOUNTS AND ANY PRINCIPAL REDUCTIONS ARE FINAL, REGARDLESS OF ANY ACTUAL, POTENTIAL OR THEORETICAL DISCREPANCIES BETWEEN THE METHODOLOGY USED BY THE EARTHQUAKE EVENT CALCULATION AGENT AND ANY OTHER POSSIBLE METHODOLOGY FOR ASSESSING THE SAME FACTS. THESE INHERENT LIMITATIONS ARE POTENTIALLY EXACERBATED BY THE POTENTIAL FOR UNRELIABLE DATA, OR THE UNAVAILABILITY OF DATA.

INVESTORS IN THE NOTES WILL HAVE NO RIGHT TO ENFORCE OR TAKE ACTIONS AGAINST AIR OR ANY RIGHT UNDER THE EARTHQUAKE EVENT CALCULATION AGENT AGREEMENT OR IN CONNECTION THEREWITH.

ANY EXTREME PRECIPITATION EVENT WOULD RESULT IN A REDUCTION IN THE OUTSTANDING NOMINAL AMOUNT OF THE NOTES TO THE EXTENT OF THE EXTREME PRECIPITATION SUBLIMIT, AND IN A CORRESPONDING REDUCTION IN THE INTEREST ON THE NOTES. ANY EXTREME PRECIPITATION EVENT MAY HAVE CHARACTERISTICS NOT CONSIDERED IN THE EXTREME PRECIPITATION REPORT.

JBA DOES NOT REPRESENT INVESTORS IN THE NOTES OR THEIR INTERESTS IN ANY WAY. JBA DOES NOT SPONSOR, ENDORSE, OFFER, SELL, OR PROMOTE THE NOTES, NOR DOES IT MAKE ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, TO ANY PERSON, REGARDING THE ADVISABILITY OF INVESTING IN THE NOTES OR THE LEGALITY OF AN INVESTMENT IN THE NOTES.

NONE OF ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE EARTHQUAKE EVENT CALCULATION AGENT, THE COUNTRY OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES, OR ANY OF THEIR RESPECTIVE DIRECTORS OR OFFICERS, HAS INDEPENDENTLY VERIFIED ANY OF THE HISTORICAL INFORMATION INCLUDED IN THE EXTREME PRECIPITATION REPORT.

JBA PROVIDES SERVICES TO ADB, THE INITIAL PURCHASER, THE COUNTRY AND THEIR RESPECTIVE AFFILIATES IN RESPECT OF THE PROPOSED OFFERING AND MAY PROVIDE SUCH TYPE OF SERVICES AND MAY ENGAGE IN OTHER TYPES OF BUSINESS WITH ADB, THE INITIAL PURCHASER, THE SOLE STRUCTURING AGENT, THE COUNTRY OR ANY OF THEIR RESPECTIVE AFFILIATES IN THE FUTURE.

The Risk Transfer Agreement is subject to early termination based on specified events relating to changes of law and defaults by the Country or ADB, and such an early termination would result in redemption of the Notes. See "*—The Notes—Maturity and Extension; Redemption Terms—Risk Transfer Termination Event*" and "*The Risk Transfer Transaction*". |

#### ADDITIONAL RISK FACTORS
***An investment in the Notes entails significant risks. Investors should read the risks summarized below in connection with, and the risks summarized below are qualified by reference to, the risks described in more detail in the "Risk Factors" section beginning on page 12 of the Prospectus and in the "Additional Risk Factors" section on page S-3 of the Capital at Risk Notes Prospectus Supplement dated 1 April 2026.***

#### An investment in the Notes is speculative and involves a high degree of risk.
The Notes are complex speculative instruments and are intended for sale only to investors capable of understanding and assuming the high risks entailed in such instruments. Potential investors are strongly encouraged to consult with their financial, legal, actuarial and tax advisors before making any investment decision in respect of the Notes.

#### Noteholders may lose all or a portion of their investment.
The Noteholders could lose all or a portion of the principal of, and interest on, the Notes, if during the Risk Period there are one or more Applicable Events resulting in Principal Reductions for the Notes. The possibility of the occurrence of one or more Applicable Events that result in Principal Reductions, and the frequency and severity of any such Applicable Events, are inherently unpredictable and, therefore, the risk of loss to Noteholders cannot be predicted. Furthermore, holders of the Notes are exposed to the credit risk of ADB. Any failure of ADB to make a payment on the Notes, whether due to the creditworthiness of ADB or for any other reason, may result in a loss to holders of the Notes.

**The Notes are linked to the performance of an interest rate index (i.e., Compounded SOFR), as applied to a principal amount that may decrease. Accordingly, the Notes are subject to risks that are not associated with a conventional debt security, which may result in the reduction of the interest and/or principal payable on the Notes.**

Interest payable on the Notes is determined by reference to an interest rate index (i.e., Compounded SOFR), as applied to a principal amount that may decrease. An investment in the Notes entails significant risks not associated with investments in conventional debt securities, including the risk that the resulting interest rate will be less than that payable on a fixed rate security issued by ADB at the same time and that the investor could lose all or a substantial portion of the principal of the Notes. The secondary market for the Notes, if any, will be affected by a number of factors independent of the creditworthiness of ADB and the value of the applicable interest rate index, including the volatility of such interest rate index, the method of calculating the index, the time remaining to the maturity of the Notes, the Outstanding Nominal Amount of the Notes, market interest rates and the occurrence or expected occurrence of Applicable Events and any associated Principal Reductions or expected Principal Reductions. The value of the applicable interest rate index should not be taken as an indication of the future performance of such interest rate index during the term of the Notes.

#### SOFR has a limited history, and its historical performance is not indicative of future performance.
The Federal Reserve Bank of New York began to publish SOFR in April 2018. Although the Federal Reserve Bank of New York has also begun publishing historical indicative SOFR going back to 2014, such historical indicative data inherently involves assumptions, estimates and approximations. Therefore, SOFR has limited performance history and no actual investment based on the performance of SOFR was possible before April 2018. The level of SOFR over the term of the Notes may bear little or no relation to the historical level of SOFR. The future performance of SOFR is impossible to predict and therefore no future performance of SOFR or the Notes may be inferred from any of the hypothetical or actual historical performance data. Hypothetical or actual historical performance data are not indicative of the future performance of SOFR or the Notes. Changes in the levels of SOFR will affect Compounded SOFR and, therefore, the return on the Notes and the trading price of the Notes, but it is impossible to predict whether such levels will rise or fall. There can be no assurance that SOFR or Compounded SOFR will be positive.

------

#### Compounded SOFR with respect to a particular Interest Period will only be capable of being determined near the end of the relevant Interest Period.
The level of Compounded SOFR applicable to a particular Interest Period and, therefore, the amount of interest payable with respect to such Interest Period will be determined on the Interest Determination Date for such Interest Period. Because each such date is near the end of such Interest Period, you will not know the amount of interest payable with respect to a particular Interest Period until shortly prior to the related Specified Interest Payment Date or Redemption Amount Payment Date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each such Specified Interest Payment Date or Redemption Amount Payment Date. In addition, some investors may be unwilling or unable to trade the Notes without changes to their information technology systems, both of which could adversely impact the liquidity and trading price of the Notes.

**The SOFR Index may be modified or discontinued and the Notes may bear interest by reference to a rate other than Compounded SOFR, which could adversely affect the value of the Notes.**

The SOFR Index is published by the Federal Reserve Bank of New York based on data received by it from sources other than ADB, and ADB has no control over its methods of calculation, publication schedule, rate revision practices or availability of the SOFR Index at any time. There can be no guarantee that the SOFR Index will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which the SOFR Index is calculated, including the manner in which SOFR is calculated, is changed, that change may result in a reduction in the amount of interest payable on the Notes and the trading prices of the Notes. In addition, the Federal Reserve Bank of New York may withdraw, modify or amend the published SOFR Index in its sole discretion and without notice. Compounded SOFR for any Interest Period will not be adjusted for any modifications or amendments to the SOFR Index that the Federal Reserve Bank of New York may publish after Compounded SOFR for that Interest Period has been determined.

If ADB determines that a Benchmark Transition Event (as that term is set forth in the Pricing Supplement) and its related Benchmark Replacement Date (as that term is set forth in the Pricing Supplement) have occurred in respect of the SOFR Index or SOFR itself, then the interest payable on the Notes for any Interest Period will no longer be determined by reference to the SOFR Index, but instead will be determined by reference to a different rate, plus a spread adjustment, which is referred to as a "Benchmark Replacement," as further described in Annex I ("*Effect of a Benchmark Transition Event*") to the Pricing Supplement.

If a particular Benchmark Replacement (as that term is set forth in the Pricing Supplement) or Benchmark Replacement Adjustment (as that term is set forth in the Pricing Supplement) cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected, recommended or formulated by (i) the Relevant Governmental Body (as that term is set forth in the Pricing Supplement), (ii) the International Swaps and Derivatives Association ("**ISDA**") or (iii) in certain circumstances, ADB itself. In addition, the terms of the Notes expressly authorize ADB to make Benchmark Replacement Conforming Changes (as that term is set forth in the Pricing Supplement) with respect to, among other things, changes to the definition of "Interest Period", the timing and frequency of determining rates and making payments of interest and other administrative matters. The determination of a Benchmark Replacement, the calculation of the interest payable on the Notes for any Interest Period by reference to a Benchmark Replacement (including the application of a Benchmark Replacement Adjustment), any implementation of Benchmark Replacement Conforming Changes and any other determinations, decisions or elections that may be made under the terms of the Notes in connection with a Benchmark Transition Event, could adversely affect the value of the Notes, the return on the Notes and the price at which you can sell such Notes.

In addition, (i) the composition and characteristics of the Benchmark Replacement will not be the same as those of Compounded SOFR, the Benchmark Replacement may not be the economic equivalent of Compounded SOFR, there can be no assurance that the Benchmark Replacement will perform in the same way as Compounded SOFR would have at any time and there is no guarantee that the Benchmark Replacement will be a comparable substitute for Compounded SOFR (each of which means that a Benchmark Transition Event could adversely affect the value of the Notes, the return on the Notes and the price at which you can sell the Notes), (ii) any failure of the Benchmark Replacement to gain market acceptance could adversely affect the Notes, (iii) the Benchmark Replacement may have a very limited history and the future performance of the Benchmark Replacement may not be predicted based on historical performance, (iv) the secondary trading market for Notes linked to the Benchmark Replacement may be limited and (v) the administrator of the Benchmark Replacement may make changes that could change the value of the Benchmark Replacement or discontinue the Benchmark Replacement and has no obligation to consider your interests in doing so.

------

**The Calculation Agent will make certain determinations with respect to the Notes, and ADB may exercise subjective discretion with respect to Compounded SOFR or replacements thereof.**

The Calculation Agent will make certain determinations with respect to the Notes as further described under Paragraph 17 ("**Floating Rate Note Provisions**") of the Pricing Supplement. Any determination, decision or election pursuant to the benchmark replacement provisions will be made by ADB. Any of these determinations may adversely affect the value of the Notes, the return on the Notes and the price at which you can sell such Notes. Moreover, certain determinations to be made by ADB may require the exercise of discretion and the making of subjective judgments, such as with respect to Compounded SOFR or the occurrence or non-occurrence of a Benchmark Transition Event and any Benchmark Replacement Conforming Changes. These potentially subjective determinations may adversely affect the value of the Notes, the return on the Notes and the price at which you can sell such Notes.

#### The maturity of the Notes may be extended.
In certain circumstances, an Extension Event may occur with respect to all or a portion of the Notes, resulting in one or more Extension Periods for the Notes. In the case of where a Partial Extension Notice is given, interest during the relevant Extension Period will only be payable on that portion of the Notes that has been extended and not on that portion of the Notes that has been redeemed and has not been extended. Whether an Extension Event will occur with respect to all or a portion of the Notes is unpredictable. Interest payable on the Notes during the Extension Periods will no longer include the applicable Risk Margin that was effective prior to the Extension Periods, but rather will include a reduced Risk Margin.

#### The Notes may be redeemed before the Scheduled Maturity Date, including in circumstances where the Risk Transfer Agreement is terminated.
If a Mandatory Redemption Event occurs with respect to the Notes, the Notes may be redeemed in full or in part prior to the Scheduled Maturity Date. A Mandatory Redemption Event may result from a Reporting Agency Failure Event (as discussed under "*Overview—Maturity and Extension; Redemption Terms—Reporting Agency Failure Event*") or an Event Calculation Agent Failure Event (as discussed under "*Overview—Maturity and Extension; Redemption Terms—Event Calculation Agent Failure Event*"), in each case under either Event Calculation Agent Agreement. Upon the occurrence of a Reporting Agency Failure Event or Event Calculation Agent Failure Event under the Earthquake Event Calculation Agent Agreement, the Outstanding Nominal Amount of Notes equal to the Earthquake Sublimit, to the extent not previously reduced by any Principal Reduction on account of any Earthquake Event prior to such redemption, will be redeemed. Upon the occurrence of a Reporting Agency Failure Event or Event Calculation Agent Failure Event under the Extreme Precipitation Event Calculation Agent Agreement, the Outstanding Nominal Amount of Notes equal to the Extreme Precipitation Sublimit, to the extent not previously reduced by any Principal Reduction on account of any Extreme Precipitation Event prior to such redemption, will be redeemed.

A Mandatory Redemption Event may also result from a Risk Transfer Termination Event, which may be triggered by certain events with respect to the Risk Transfer Agreement, including by certain defaults of ADB or the Country thereunder, or by changes in applicable laws as described in the Risk Transfer Agreement. See "*Overview—Maturity and Extension; Redemption Terms—Risk Transfer Termination Event*" and "*The Risk Transfer Transaction*". Accordingly, any such Risk Transfer Termination Event may result in the early redemption of the Notes in full.

Under the Risk Transfer Agreement, certain amendments to, changes in, issuances of, or clarifications of the laws of the Country may constitute a "Change of Law", and could result in a Full Mandatory Redemption Event with respect to the Notes. Accordingly, the Country may have an ability to cause a Full Mandatory Redemption Event to occur with respect to the Notes.

If the Notes are redeemed in full or in part prior to the Scheduled Maturity Date, holders of the Notes will not have the opportunity to continue to accrue and be paid interest after the applicable redemption date with respect to the Notes so redeemed. Such holders may have to reinvest any amount received as a result of such redemption in a lower interest rate environment and may be unable to reinvest any such amount in investments with a yield equal to or greater than the yield of the Notes.

#### The market for the Notes, if one exists , may be highly volatile, and the liquidity of the Notes may be limited.
There is currently no secondary market for the Notes, and one might never develop. Neither the Initial Purchaser nor any of its respective affiliates is under any obligation to make a market in the Notes, and to the extent that such market making is commenced, it may be discontinued at any time. The Notes will be issued only in denominations of U.S.$250,000 and integral multiples of U.S.$1,000 in excess thereof.

------

There can be no assurance that a secondary market will develop for the Notes. Even if a secondary market for the Notes develops, the price for which Noteholders can sell the Notes in the secondary market may exhibit substantial volatility before, during or after the occurrence of any Applicable Event or potential Applicable Event.

Any secondary market may not provide significant liquidity and may not continue until the Notes is redeemed. Transaction costs in any secondary market could be high. In addition, if an Applicable Event (or potential Applicable Event or other significant natural peril catastrophe) occurs, the liquidity of the Notes may be materially impaired. As a result, the difference between bid and ask prices for the Notes in any secondary market could be substantial. If Noteholders sell their Notes before maturity, such Noteholders may have to do so at a discount from the initial Issue Price, and, as a result, such Noteholders may suffer substantial losses.

The market value of the Notes may also be affected if ADB or debt issued under ADB's Global Medium-Term Note Program is downgraded by any nationally recognized statistical rating organization or if the market experiences limited liquidity. The market value of the Notes may also exhibit substantial volatility if a sizeable other material peril event occurs that affects the insurance or reinsurance industry.

#### The return on the Notes may be lower than the return on a standard debt security of comparable maturity.
The return that a Noteholder will receive on the Notes, which could be negative, may be less than the return such Noteholder could earn on other investments. Even if a Noteholder's return is positive, such Noteholder's return may be less than the return such Noteholder would earn if such Noteholder bought a conventional senior debt security of ADB with the same maturity date. A Noteholder's investment may not reflect the full opportunity cost to such Noteholder when such Noteholder takes into account factors that affect the time value of money. Unlike conventional debt securities, if one or more Applicable Events occur with respect to the Notes a Noteholder holds, such Noteholder may not receive full repayment of principal at maturity with respect to the Notes.

#### Investment in the Notes may not be legal for all investors.
Investors should consult their own legal advisors in determining whether and to what extent the Notes constitute legal investments for such investors and whether and to what extent the Notes can be used as collateral for various types of borrowings. In addition, financial institutions should consult their legal advisors or regulators in determining the appropriate treatment of the Notes under any applicable risk-based capital or similar rules.

Investors whose investment activities are subject to investment laws and regulations or to review or regulation by certain authorities may be subject to restrictions on investments in certain types of debt securities, which may include the Notes. Investors should review and consider such restrictions prior to investing in the Notes.

#### Changes in creditworthiness of ADB's borrowers may affect the financial condition of ADB.
ADB extends loans to and guarantees obligations of its developing member countries and other public sector borrowers (with a member country guarantee) and also extends loans and guarantees to and makes investments in private sector companies that support economic development in ADB's developing member countries. Changes in the macroeconomic environment and financial markets in these countries may affect the creditworthiness of borrowers and their ability to repay their obligations and may also affect the value of ADB's equity investments.

------

#### Various restrictions are applicable to the transfer of the Notes.
The Notes may be reoffered and sold only to investors who (i) are Qualified Institutional Buyers as defined in Rule 144A under the Securities Act; (ii) are residents of, and purchasing and holding the Notes in, a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction (as defined in "*Overview—Manner of Offering—Transfer Restrictions*") and (iii) meet the other requirements set forth under "*Notice to Investors—Representations of Purchasers*" at page PS-57. The Notes will not be registered under the Securities Act or any state or foreign securities laws, and transfers of Notes are subject to substantial contractual and legal restrictions. In particular, a Noteholder may not sell or offer to sell the Notes in or into any state or jurisdiction of the United States other than the Permitted U.S. Jurisdictions or in or into any jurisdiction outside of the United States other than the Permitted Non-U.S. Jurisdictions. See "*—Legal interpretations and requirements in Permitted U.S. Jurisdictions and Permitted Non-U.S. Jurisdictions are subject to change*" below. Given the risks associated with an investment in the Notes and the restrictions on transfer, investors may have difficulty locating Qualified Institutional Buyers in Permitted U.S. Jurisdictions or Permitted Non-U.S. Jurisdictions willing to purchase Notes from them. Consequently, a Noteholder may not be able to liquidate its investment readily, and the Notes may not be readily accepted as collateral for loans. Prospective investors should proceed on the assumption that they may have to bear the economic risk of an investment in the Notes until their maturity.

#### Legal interpretations and requirements in Permitted U.S. Jurisdictions and Permitted Non-U.S. Jurisdictions are subject to change.
The laws and regulations of the Permitted U.S. Jurisdictions and the Permitted Non-U.S. Jurisdictions contain broad definitions of the activities that may constitute the conduct of the business of insurance in such jurisdictions. The terms of the Notes are such that they could be construed to constitute insurance or reinsurance contracts in these jurisdictions, insofar as they expose the holders to certain insurance or reinsurance related risks, and accordingly subject the investor to regulation as a provider of insurance or reinsurance coverage.

The offering has been designed so that, in each of the Permitted U.S. Jurisdictions and Permitted Non-U.S. Jurisdictions, investors in the Notes should not be required solely by reason of such investment to be licensed as an insurer or reinsurer in such state or jurisdiction. This approach is based upon market conventions for securities of other issuers having characteristics similar to the Notes and interpretations (either written or oral) provided by the staff of the insurance regulatory body or in certain cases local counsel in such states and jurisdictions with respect to securities of other issuers having similar characteristics to the Notes. Such interpretations were issued years ago (in most cases, more than twenty years ago) and have not been and will not be updated in connection with the offering of the Notes. Insurance regulatory authorities have broad discretionary powers to modify or withdraw regulatory interpretations, and such interpretations and the written advice of counsel received with respect to the laws of the Permitted U.S. Jurisdictions and the Permitted Non-U.S. Jurisdictions are not binding on a court or any third party and may be subject to challenge in administrative or judicial proceedings. There can be no assurance that such interpretations and advice will remain in effect or as to the outcome of any such third-party challenge. Noteholders are not and will not be permitted to transfer Notes into a jurisdiction that is not a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction.

Any person who holds any interest in the Notes, who does not reside and hold such interest in a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction, may be forced to transfer such interest to a person in a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction.

#### The market for unrated securities is subject to disruptions that could have an adverse effect on the market price of the Notes.
The Notes are not rated. As a result, holders of the Notes bear the risks associated with an investment in unrated debt. Generally, the market for unrated securities has been subject to increased volatility in the prices of such securities and reduced liquidity for the holders of such securities.

**There can be no assurance that the Country will make disbursements in accordance with the standard operating procedures described in the "The Risk Transfer Transaction" section in an amount equal to the proceeds under the Risk Transfer Agreement.**

Under the Risk Transfer Agreement, the Country agreed that payments it receives from ADB upon a Principal Reduction shall be paid to vulnerable persons in the Country in accordance with standard operating procedures acceptable to ADB and adopted prior to issue of the Notes. However, no assurance can be provided that the Country will make disbursements in accordance with such procedures in an amount equal to the proceeds under the Risk Transfer Agreement. Even if the Country does make disbursements in accordance with such procedures in such amount, there can be no assurance as to the fairness, equity, efficiency and/or timeliness of payment to vulnerable persons in the Country. Any failure by the Country to comply with such procedures or to make disbursements in such amount does not constitute or give rise to a breach or an event of default under the Notes.

------

Although the standard operating procedures contemplate certain practices with respect to reporting and application of payments, any failure by the Country to conform to these practices does not constitute or give rise to a breach or an event of default under the Notes.

None of the Initial Purchaser and the Sole Structuring Agent makes any representation or warranty, express or implied, to any person of the application of any payment under the Risk Transfer Agreement or is responsible for the ongoing monitoring of the application of any payment under the Risk Transfer Agreement.

#### Risks Relating to GEM, AIR, JBA and Certain Other Risks
***THE DISCLAIMERS SET FORTH IN THE SECTION ENTITLED "GEM DISCLAIMERS" REGARDING THE EARTHQUAKE EXPERT RISK ANALYSIS REPORT AND GEM MODEL, THE DISCLAIMERS SET FORTH IN THE SECTION ENTITLED "AIR DISCLAIMERS" REGARDING THE EARTHQUAKE EVENT CALCULATION AGENT AGREEMENT AND THE DISCLAIMERS SET FORTH IN THE SECTION ENTITLED "JBA DISCLAIMERS" REGARDING THE EXTREME PRECIPITATION REPORT, EXTREME PRECIPITATION DATA FILE AND THE EXTREME PRECIPITATION EVENT CALCULATION AGENT AGREEMENT APPLY TO THIS "ADDITIONAL RISK FACTORS" SECTION. THESE ADDITIONAL RISK FACTORS THAT RELATE TO GEM, AIR AND JBA ARE PROVIDED BY GEM, AIR AND JBA AS OF THE DATE HEREOF.***

#### Output from the use of different models may differ, in some cases significantly, from the output reflected in the Earthquake Expert Risk Analysis Results.
The Country may use for its own risk management purposes its own internal model or third-party vendor models, which may produce significantly different results from that reflected in the Earthquake Expert Risk Analysis Results attached as Appendix E-II hereto. The Initial Purchaser and the Sole Structuring Agent (or any of their respective affiliates) are financial institutions, (re)insurance companies or (re)insurance intermediaries serving many clients, including ADB. In the ordinary course of business, each of the Initial Purchaser and the Sole Structuring Agent (or any of its respective affiliates) may become privy to client-generated model output or may generate other model output using internal or third-party vendor models. Such output may differ, in some cases significantly, from the output reflected in the Earthquake Expert Risk Analysis Results attached as Appendix E-II hereto or the corresponding Earthquake Data File (see Appendix E-III). None of the Country, the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates intend to, and none of them will be required to, disclose the results of those models to any purchaser of the Notes.

#### The Earthquake Expert Risk Analysis Report is for illustrative purposes only.
The data and methodology described in the Earthquake Expert Risk Analysis Report, and the analyses, estimates and services described therein, are provided "as is" without warranty or any guaranty of any kind to the investors in the Notes. These analyses and estimates are provided for illustrative purposes only and are not intended to provide, nor should they be interpreted as providing, any facts regarding, or any guaranty or prediction or forecast of, the likelihood that investors in the Notes will receive payment thereon. Notwithstanding the analyses, estimates and assumptions set forth in this Prospectus Supplement and in the Earthquake Expert Risk Analysis Report, one or more Earthquake Events could occur at any time during the Risk Period of the Notes. Any such Earthquake Events could result in a Principal Reduction with respect to the Notes. Any such Earthquake Event may have characteristics similar to or different from those of simulated events that did not qualify as Earthquake Events in the Earthquake Expert Risk Analysis Report, or characteristics not considered in the Earthquake Expert Risk Analysis Report.

GEM does not represent investors in the Notes or their interests in any way. GEM does not sponsor, endorse, offer, sell, or promote the Notes, nor does it make any representation or warranty, express or implied, to any person, regarding the advisability of investing in the Notes or the legality of an investment in the Notes. GEM is not responsible for the determination of the structure or the pricing of the Notes. Furthermore, GEM has no obligation or liability to any person in connection with the administration, marketing, or trading, if any, of the Notes or liability for any adverse financial result or any direct, indirect, special, punitive or consequential damages whatsoever. GEM makes no representation or warranty, express or implied, to any person, as to the accuracy or completeness of any information set forth in this Prospectus Supplement or any supplement hereto, including information provided in the Earthquake Expert Risk Analysis Report. GEM assumes no responsibility for the content of any agreements to which it is not a signatory, and in particular (but not by way of limitation) has no responsibility for ensuring that the procedures and provisions of any such agreements are consistent with this Prospectus Supplement or with any other agreement executed in connection with the Notes.

------

In the development of the GEM Model, GEM has relied on published technical papers and studies, catalogs and other data sources relevant to the perils upon which the GEM Model are based, and has selected those that it believes to represent credible scientific opinion related to the specific perils. However, since no scientific consensus on models or risk parameters exists, GEM acknowledges (and investors in the Notes are deemed to acknowledge) that other credible, published models and/or risk parameters may exist that, if used, could produce materially different results. The GEM Model does not predict the probabilistic occurrence of any catastrophic events. GEM has not verified the authenticity or accuracy of the original data in the historical catalogs or other data sources used to develop the GEM Model. GEM also has not verified the authenticity or accuracy of all of the original data in the historical catalogs or other data sources used to develop the GEM Model. Prior to investing in the Notes, investors should consult their own expert advisors whose conclusions may differ from those of GEM.

The GEM Model assumes a Poisson distribution of event occurrence for earthquakes and, as such, the probability of an event is not influenced by the timing of the last event, and the possible contribution of clustering of seismicity in time and space is neglected. Accordingly, the expected loss estimates and related probabilities produced by GEM for the Notes do not and cannot consider the occurrence of related shocks affecting the same region. Such related shocks could have the potential for multiple Earthquake Payout Amounts, with the possibility that any Earthquake Box Location may contribute to an Earthquake Payout Amount in more than one Earthquake Event.

No model of catastrophic events is, or could be, an exact representation of reality. The GEM Model rely on various methodologies and assumptions, some of which are subjective and subject to uncertainty, and which might not be used in models produced by other modeling firms. Furthermore, there may be material differences in the way in which these elements are considered by other modeling firms. Consequently, there can be no assurance that the GEM Model represents an accurate estimation of the risk of loss or the amount of any Principal Reduction with respect to the Notes. Accordingly, the expected loss estimates and related probabilities produced by the GEM Model are themselves subject to uncertainty. GEM reviews model assumptions from time to time in view of new data and other information to refine and modify its models as such information becomes available. As such, the GEM Model may not necessarily reflect the most current scientific research or the most current models of GEM at any time. Estimates generated by such refined or modified models may materially differ from the estimates generated by the GEM Model in connection with the Notes, and the use of such models in lieu of the GEM Model might similarly materially alter the information provided in the Earthquake Expert Risk Analysis Report.

The results of GEM's analysis should not be viewed as facts or forecasts of future events, or of any reduction in the Outstanding Nominal Amount of, and interest on, the Notes, and should not be relied upon as a representation of the current or future value of the Notes. Considerable uncertainty exists in the assumptions and parameters used in the Earthquake Expert Risk Analysis Report, arising from insufficient data, limited scientific knowledge and alternative empirical relationships, as well as from the random nature of Earthquakes. Such uncertainties exist in, but are not limited to, estimates of Earthquake location, frequency, intensity and depth. The GEM Model cannot incorporate all sources of uncertainty. Furthermore, the assumptions and methodologies used by GEM do not constitute the exclusive set of reasonable assumptions and may not be correct. Use of alternative assumptions and/or models could yield results materially different from those produced by GEM. GEM also did not elicit from other experts alternative interpretations of its data or methods, nor did GEM research all potentially available interpretations of such data and methods on the basis that GEM considered its own interpretations to be more reliable.

The modeled Principal Reductions and related probabilities generated by the GEM Model are not necessarily predictive of future Earthquakes. Investors in the Notes should not view the expected loss estimates and related probabilities generated by the GEM Model as predicting the likelihood of the occurrence during the Risk Period of the Notes of one or more Earthquake Events resulting in a Principal Reduction for the Notes. GEM has not made any effort, nor does it have the ability, to predict Earthquake Events affecting the Notes. Accordingly, the actual frequency and severity of Earthquake Events could differ materially from the frequency and severity estimated by GEM.

The Earthquake Expert Risk Analysis Report is included herein and made available to investors in reliance upon GEM as an expert in such matters. See "*Experts.*" The Earthquake Expert Risk Analysis Report is, as noted above, based on certain assumptions, judgments, and methodologies of GEM, a number of which are confidential and proprietary to GEM.

As a result of its ongoing process of internal review, GEM may refine its model assumptions from time to time in light of new scientific and other information as such information becomes available. Such refinements may materially alter, and have in the past materially altered, the loss estimates generated by the models. Furthermore, to the extent that GEM becomes aware of issues either in its models or in the software expression of such models which may affect their output in unintended ways, it may, depending on the materiality of the issues communicate such issues to its licensees and resolve them in subsequent versions of its models. As such, the GEM Model may not necessarily reflect the most current models of GEM at any time.

------

#### The GEM Model may not reflect the most current models of GEM.
GEM reviews model assumptions from time to time in view of new data and other information to refine and modify its models as such data and other information becomes available. GEM is currently assessing updates to the GEM Earthquake Model for Central Asia V2025.0, such as assumptions therein relating to the characteristic behavior of relevant faults and the characterization of epistemic uncertainties. Notwithstanding any ongoing assessment of its models, GEM expressly disclaims any obligation or duty to update or correct the GEM Model or any prior versions of the GEM Model. As such, the GEM Model may not reflect the most current models of GEM at any time. Estimates generated by such refined or modified models may materially differ from the estimates generated by the GEM Model in connection with this offering of Notes, and the use of such models in lieu of the GEM Model might similarly materially alter the information provided in the Earthquake Expert Risk Analysis Report. GEM has made no effort to quantify the impact of the use of such updated models on the information provided in the Earthquake Expert Risk Analysis Report and such information is based on the latest version of the GEM Model as of the date of this Prospectus Supplement.

***Foreshocks, main shocks, and aftershocks are not included in the determination of event occurrence rates in the GEM Model and will be treated as distinct Earthquakes in the calculation of Principal Reductions.***

Earthquake foreshocks and aftershocks are, respectively, earthquakes that precede or follow the primary earthquake of an earthquake sequence, generally occurring on a related section of the fault system to the primary earthquake. It is standard practice in the field of seismology to intentionally remove aftershocks from earthquake catalogs before source event rates are determined. For this reason, foreshocks and aftershocks are not considered in the determination of event occurrence rates during the development of the GEM Model.

#### No representation or liability as to the Earthquake Expert Risk Analysis Report
None of ADB, the Initial Purchaser, the Sole Structuring Agent, the Country or any of their respective affiliates and representatives, or any of their respective directors or officers, has reviewed, or makes, or shall be deemed to make, any representation with respect to the Earthquake Expert Risk Analysis Report, including (without limitation) the adequacy, completeness, appropriateness or otherwise of the Earthquake Expert Risk Analysis Report. The Earthquake Expert Risk Analysis Report is included herein and made available to investors in reliance upon GEM as an expert in such matters. See "*Experts.*" The Earthquake Expert Risk Analysis Report is, as noted above, based on certain assumptions, judgments, and methodologies of GEM, a number of which are confidential and proprietary to GEM.

Without intending to limit the foregoing, in particular, none of ADB, the Initial Purchaser, the Sole Structuring Agent, the Country or any of their respective affiliates and representatives, or any of their directors or officers, has reviewed the Earthquake Expert Risk Analysis Report to determine (i) the reasonableness of the assumptions, judgments and methodologies utilized by GEM, (ii) whether such assumptions, judgments and methodologies should be supplemented in any way through the use of alternative assumptions, judgments or methodologies, (iii) whether the assumptions, judgments and methodologies utilized by GEM include the appropriate factors that could contribute to Principal Reductions for the Notes and (iv) whether the use of alternative assumptions, judgments and methodologies, or the use of different catastrophe simulation models, could yield results materially different from those generated by the GEM Model. The actual Principal Reduction with respect to any Earthquake Event, if any, will likely differ from the Earthquake Expert Risk Analysis Report, possibly materially.

Because of the inherent limitation of relying on the Earthquake Expert Risk Analysis Report for loss estimation, and because of the subjective nature of many of GEM's assumptions, judgments and methodologies in preparing the Earthquake Expert Risk Analysis Report, each of ADB, the Initial Purchaser, the Sole Structuring Agent, the Country and each of their respective affiliates and representatives expressly disclaims any responsibility for, or any liability based upon, a finding that the Earthquake Expert Risk Analysis Report includes any untrue statement of a material fact or that the Earthquake Expert Risk Analysis Report omits to state a material fact necessary in order to make the statements, in light of the circumstances under which they were made, not misleading.

#### There may be a correlation between an earthquake that is covered under the Tajikistan Notes as well as the Notes.
The Earthquake Covered Area of the Notes and the earthquake covered area under the terms and conditions of a separate series of notes that relates to certain earthquake and extreme precipitation perils of the Republic of Tajikistan (the "**Tajikistan Notes**") and are issued by ADB on or around the issue date of the Notes are overlapping and cover the same boxes in the northern part of the Republic of Tajikistan and the southern part of the Country. An Earthquake occurring in within such area of overlapping could trigger one or both of the Notes and/or the Tajikistan Notes. Earthquake Expert Risk Analysis Results in Appendix E-II contains a projection of probability relating to such a scenario. Such projection shows that there may be some correlation between an "Earthquake Event" under the Tajikistan Notes and an Earthquake Event under the Notes, originating from the same earthquake. As a result, if an investor invests in both the Notes and the Tajikistan Notes, it is possible that a single earthquake can cause loss of principal in both the Notes and the Tajikistan Notes.

No information is being provided with respect to the Tajikistan Notes in this prospectus supplement, the Tajikistan Notes are not being offered pursuant to this prospectus supplement, and no information set forth in the prospectus supplement for the Tajikistan Notes is incorporated into this prospectus supplement.

#### The Event Parameters provided by the applicable Reporting Agency are binding and conclusive.
Any Payout Amount with respect to an Applicable Event will be calculated and determined based upon the applicable Event Parameters provided by the applicable Reporting Agency. The applicable Reporting Agency may make available from time to time several different reports which may show different levels of accuracy and precision and varying parameters. Notwithstanding the foregoing, any data released or revised after an Event Parameters Date will be disregarded by the applicable Event Calculation Agent when determining any Payout Amounts related to an Applicable Event.

Investors are advised that the factual determinations made by the applicable Reporting Agency will be final and binding (absent manifest error that is identified in a written notice received by ADB prior to the date which is three (3) Business Days following the date on which such Event Report is first made available on the Site) regardless of any actual, potential or theoretical discrepancies between the methodology used by such Reporting Agency and any other possible methodology for assessing the same underlying facts. No separate review or appraisal of the accuracy of the data reported will be performed. These inherent limitations may be exacerbated by the potential for unreliable data or the unavailability of data.

No Reporting Agency sponsors, endorses, offers or promotes the Notes, nor makes any representation or warranty, express or implied, regarding the advisability of investing in the Notes. No Reporting Agency is responsible for or has participated in the determination of the structure or pricing of the Notes. Furthermore, no Reporting Agency has any obligation or liability in connection with the administration, marketing or trading, if any, of the Notes. No Reporting Agency makes any representation or warranty, express or implied, as to the accuracy or completeness of the information contained in this Prospectus Supplement.

The applicable Event Parameters as reported by the applicable Reporting Agency will be used by the applicable Event Calculation Agent, who will be under no obligation to undertake any independent assessment of the accuracy of the parameters so reported. Moreover, different Reporting Agencies might produce different Event Parameters such that using data from one Reporting Agency over the other could result in different Payout Amount calculations.

In respect of Earthquake Events, the Primary Reporting Agency is the GFZ Potsdam (Geofon). Certain Earthquake Event Parameters published by the Primary Earthquake Reporting Agency are published automatically without human verification, and may be, and have in the past been, updated after verification, which would follow its initial publication. Although such process may be conducted prior to the Earthquake Calculation Date, there can be no assurance of such fact. In respect of Extreme Precipitation Events, the Primary Reporting Agency is European Centre for Medium-Range Weather Forecasts, or ECMWF. ERA5 data published by ECMWF will be revised when the final, quality-assured release becomes available several months following the initial/near-real-time release. For the purposes of determining the occurrence of an Extreme Precipitation Event only the ERA5T (the initial/near-real-time release) will be used, which is expected to have an approximate latency of five (5) calendar days. Notwithstanding the foregoing, any data revised after an Event Parameters Date and any data released after an Event Parameters Date, will be disregarded by the applicable Event Calculation Agent when determining whether an Applicable Event has occurred or any Earthquake Payout Amounts related to the applicable Earthquake Event.

------

The Calculation Date in respect of an Earthquake Event depends in part on when a Notice of Applicable Event is delivered. As the Earthquake Event Calculation Agent will first attempt to obtain the applicable Event Parameters on the Earthquake Calculation Date, the timing of the delivery of a Notice of Applicable Event could affect which Event Parameters are used in respect of an Applicable Event. Accordingly, when a Notice of Applicable Event is delivered could affect the Payout Amount calculation in the related Event Report.

***AIR's calculation of any Earthquake Payout Amount, which has inherent limitations, will be final and binding absent manifest error that is identified in a written notice received by ADB prior to the date which is three (3) Business Days following the date on which such Event Report is first made available on the Site (as defined under the heading "Available Information").***

The procedures to be performed by AIR in its capacity as Earthquake Event Calculation Agent will result in a determination as to whether an Earthquake Event has occurred and/or the extent thereof. The determination will be performed in accordance with the methodologies described in this Prospectus Supplement and as specified in the Earthquake Event Calculation Agent Agreement. The terms of the Notes provide that all determinations made by AIR, as the Earthquake Event Calculation Agent, are final and binding, absent manifest error that is identified in a written notice received by ADB prior to the date which is three (3) Business Days following the date on which such Event Report is first made available on the Site. In the event that ADB receives a written notice identifying a potential manifest error in an Event Report relating to an Earthquake Event, then as soon as practicable, but in no event later than two (2) Business Days following receipt of such notice, ADB will, in consultation with the Earthquake Event Calculation Agent, determine whether such potential manifest error constitutes a manifest error. No separate review or appraisal of the accuracy of the defined methodologies or data used will be performed.

Investors are advised that the calculation of Earthquake Payout Amounts and any related Principal Reductions are final, regardless of any actual, potential or theoretical discrepancies between the methodology used by the Earthquake Event Calculation Agent and any other possible methodology for assessing the same facts. These inherent limitations are potentially exacerbated by the potential for unreliable data, or the unavailability of data.

***The Extreme Precipitation Report does not provide any stochastic modeling results or any facts regarding, or any guaranty or prediction or forecast of, the likelihood of an Extreme Precipitation Event during the Risk Period for the Notes.***

There are no stochastic modeling results provided by JBA or any other person in respect of any Extreme Precipitation Event that may occur prior to the maturity of the Notes, and accordingly the peril of Extreme Precipitation Events are "unmodeled". Some investors who would otherwise be interested in investing in securities similar to the Notes may be prohibited or discouraged from investing in the Notes due to the unmodeled nature of Extreme Precipitation risks, and as a result there may be less liquidity in the secondary market for the Notes.

The data and methodology described in the Extreme Precipitation Report, and the analyses and services described therein, are for illustrative and explanatory purposes only and are provided "as is" without warranty or any guaranty of any kind to the investors in the Notes. Historical analysis of the extreme precipitation events is not indicative of any probability of the occurrence of a future Extreme Precipitation Event. These analyses are not intended to provide, nor should they be interpreted as providing, any facts regarding, or any guaranty or prediction or forecast of, the likelihood that investors in the Notes will receive payment thereon. An Extreme Precipitation Event could occur at any time during the Risk Period of the Notes or, if an Extreme Precipitation Event Period commences before but has not concluded when the Risk Period expires, beyond the Risk Period. Such an Extreme Precipitation Event will result in a Principal Reduction with respect to the Notes. JBA has not modeled, nor has it simulated, any Extreme Precipitation Event. JBA has not made any effort, nor does it have the ability, to predict any Extreme Precipitation Event affecting the Notes.

JBA does not represent investors in the Notes or their interests in any way. JBA does not sponsor, endorse, offer, sell, or promote the Notes, nor does it make any representation or warranty, express or implied, to any person, regarding the advisability of investing in the Notes or the legality of an investment in the Notes. JBA is not responsible for the determination of the structure or the pricing of the Notes. Furthermore, JBA has no obligation or liability to any person in connection with the administration, marketing, or trading, if any, of the Notes or liability for any adverse financial result or any direct, indirect, special, punitive or consequential damages whatsoever. JBA makes no representation or warranty, express or implied, to any person, as to the accuracy or completeness of any information set forth in this Prospectus Supplement or any supplement hereto, including information provided in the Extreme Precipitation Report. JBA assumes no responsibility for the content of any agreements to which it is not a signatory, and in particular (but not by way of limitation) has no responsibility for ensuring that the procedures and provisions of any such agreements are consistent with this Prospectus Supplement or with any other agreement executed in connection with the Notes.

------

***The Primary Extreme Precipitation Reporting Agency and the Back-up Extreme Precipitation Reporting Agency may produce different Extreme Precipitation Event Parameters, and using data from one Reporting Agency instead of the other could affect whether an Extreme Precipitation Event does or does not occur.***

The Back-up Extreme Precipitation Reporting Agency is the National Aeronautics and Space Administration Global Precipitation Measurement, or GPM. GPM data is near-real time data, and so the GPM data, when used, will be converted using area-weighted aggregation for each Extreme Precipitation Location for purposes of consistency with ERA5 data. In addition, since GPM data reports all precipitation, regardless of whether any given precipitation takes the form of rain or snow, GPM data will be used directly as the rainfall input for Extreme Precipitation Levels without filtering out any snowfall amounts. As a result, the Extreme Precipitation Event Parameter relating to precipitation level on any given Extreme Precipitation Date for any Extreme Precipitation Location reported by the Back-up Extreme Precipitation Reporting Agency could be higher than that reported (or that, if available, would be reported) for the same day and Extreme Precipitation Location by the Primary Extreme Precipitation Reporting Agency. In addition, GPM data does not provide temperature data, and so when the Event Parameters relating to temperature is unavailable from the Primary Extreme Precipitation Reporting Agency, the Extreme Precipitation Event Calculation Agent will use mean temperature derived from historical data previously reported by the Primary Extreme Precipitation Reporting Agency, as further described in the Extreme Precipitation Event Calculation Agent Agreement. Accordingly, due to the different methodology utilized by the Primary Extreme Precipitation Reporting Agency and the Back-up Extreme Precipitation Reporting Agency, the two Extreme Precipitation Reporting Agencies may produce different Extreme Precipitation Event Parameters such that using data from one Reporting Agency instead of the other could affect whether an Extreme Precipitation Event does or does not occur.

***Extreme Precipitation Locations at the border of the Extreme Precipitation Covered Area get allocations from neighboring cells which extend beyond the boundary of the Extreme Precipitation Covered Area.***

A number of Extreme Precipitation Locations at the border of the Extreme Precipitation Covered Area get allocations from neighboring cells which extend into an area outside the Extreme Precipitation Covered Area. Hence, rainfall occurring outside of the Extreme Precipitation Covered Area might influence the Extreme Precipitation Event Index Value.

#### An Extreme Precipitation Event Period may extend beyond the Risk Period.
If an Extreme Precipitation Event Period commences within the Risk Period but does not end on or prior to the last day of the Risk Period, regardless of the fact that the Risk Period has expired, whether an Extreme Precipitation Event has occurred will continue to be determined until the expiry of such Extreme Precipitation Event Period. As a result, a Principal Reduction on account of an Extreme Precipitation Event can occur even after the expiry of the Risk Period, and rainfall following the expiry of the Risk Period can factor into whether an Extreme Precipitation Event occurs.

#### An Extreme Precipitation Payout Amount, if any, may bear little or no relation to the actual loss caused by an Extreme Precipitation Event.
If an Extreme Precipitation Event is determined to occur at any time during the Risk Period for the Notes, a Principal Reduction that equals the entire Extreme Precipitation Sublimit will occur. In such a case, the Extreme Precipitation Payout Amount may bear little or no relation to the actual loss to the Country caused by such an Extreme Precipitation Event.

#### No representation or liability as to the Extreme Precipitation Report
None of the Initial Purchaser, the Sole Structuring Agent, the Country or any of their respective affiliates and representatives, or any of their respective directors or officers, has reviewed, or makes, or shall be deemed to make, any representation with respect to the Extreme Precipitation Report, including (without limitation) the adequacy, completeness, appropriateness or otherwise of the Extreme Precipitation Report.

The Extreme Precipitation Report is, as noted above, based on certain assumptions, judgments and methodologies of JBA, a number of which are confidential and proprietary to JBA.

------

***JBA's determination as to whether an Extreme Precipitation Event has occurred, which has inherent limitations, will be final and binding absent manifest error that is identified in a written notice received by ADB prior to the date which is three (3) Business Days following the date on which such Event Report is first made available on the Site (as defined under the heading "Available Information").***

The procedures to be performed by JBA in its capacity as Extreme Precipitation Event Calculation Agent will result in a determination as to whether an Extreme Precipitation Event has occurred and/or the extent thereof. The determination will be performed in accordance with the methodologies described in this Prospectus Supplement and as specified in the Extreme Precipitation Event Calculation Agent Agreement. The terms of the Notes provide that all determinations made by JBA, as the Extreme Precipitation Event Calculation Agent, are final and binding, absent manifest error that is identified in a written notice received by ADB prior to the date which is three (3) Business Days following the date on which such Event Report is first made available on the Site. In the event that ADB receives a written notice identifying a potential manifest error in an Event Report relating to an Extreme Precipitation Event, then as soon as practicable, but in no event later than two (2) Business Days following receipt of such notice, ADB will, in consultation with the Extreme Precipitation Event Calculation Agent, determine whether such potential manifest error constitutes a manifest error. No separate review or appraisal of the accuracy of the defined methodologies or data used will be performed.

Investors are advised that the determination as to whether an Extreme Precipitation Event has occurred and the calculation of any related Principal Reduction are final, regardless of any actual, potential or theoretical discrepancies between the methodology used by the Extreme Precipitation Event Calculation Agent and any other possible methodology for assessing the same facts. These inherent limitations are potentially exacerbated by the potential for unreliable data, or the unavailability of data.

***Each of GEM, AIR and JBA has, and may in the future have, relationships with ADB, the Initial Purchaser, the Sole Structuring Agent, the Country and potential purchasers of the Notes.***

Each of GEM, AIR and JBA provides consulting services and other services, including to the insurance industry. ADB, the Initial Purchaser, the Sole Structuring Agent, the Country or any of their respective affiliates may engage any of GEM, AIR and JBA to provide consulting services or enter into other types of business relations with GEM, AIR and/or JBA from time to time. Each of GEM, AIR and JBA also provides services from time to time to potential purchasers of the Notes. GEM also has certain other relationships with certain parties relating to the Notes as further described under "*—Conflicts of Interest*" below.

ADB has agreed to pay the fees and expenses of GEM for services provided in preparation of the Earthquake Expert Risk Analysis Report. In addition, ADB has agreed under the GEM Engagement Letter to indemnify GEM in respect of certain claims, losses and expenses arising from or relating to the services provided by GEM under the GEM Engagement Letter. Subject to certain exceptions, ADB will be reimbursed for such payments by the Country.

ADB has agreed to pay the fees and expenses of AIR in its capacity as the Earthquake Event Calculation Agent and for other services. In addition, ADB has agreed under the Earthquake Event Calculation Agent Agreement to indemnify AIR in respect of certain claims, losses and expenses arising from or relating to the services provided by AIR under the Earthquake Event Calculation Agent Agreement. Subject to certain exceptions, ADB will be reimbursed for such payments by the Country.

ADB has agreed to pay the fees and expenses of JBA in its capacity as the Extreme Precipitation Event Calculation Agent and for other services. In addition, ADB has agreed under the Extreme Precipitation Event Calculation Agent Agreement to indemnify JBA in respect of certain claims, losses and expenses arising from or relating to the services provided by JBA under the Extreme Precipitation Event Calculation Agent Agreement. Subject to certain exceptions, ADB will be reimbursed for such payments by the Country.

#### None of GEM, AIR and JBA has direct contractual liability to Noteholders.
GEM has provided its analyses, expected loss estimates and related probabilities as contained within the Earthquake Expert Risk Analysis Report. JBA has provided a description of the index methodology and certain historical analysis in the Extreme Precipitation Report. AIR will act as Earthquake Event Calculation Agent, and JBA will act as Extreme Precipitation Event Calculation Agent, in each case for the Notes. Noteholders will have no right to enforce or take actions against any of GEM, AIR or JBA or any right under either Event Calculation Agent Agreement or in connection therewith. ADB's use of the information provided by GEM, AIR and/or JBA, particularly with regard to any disclosure made in or omitted from this Prospectus Supplement, is completely within ADB's sole discretion, and not the responsibility of GEM, AIR or JBA.

#### Change of Law
The structure of the Notes, as well as the structure of the Risk Transfer Agreement, is based on the legal systems and administrative practice in each relevant jurisdiction in effect as at the date of this Prospectus Supplement. No assurance can be given as to the impact of any possible change in law or to administrative practice in any of the relevant jurisdictions after the date of this Prospectus Supplement, nor can any assurance be given as to whether any such change could adversely affect the ability of ADB to make payments under the Notes, as to whether any potential investor may acquire or hold a Note in a given jurisdiction, or as to whether the Notes may be subject to prepayment. See also "*Additional Risk Factors— The Notes may be redeemed before the Scheduled Maturity Date, including in circumstances where the Risk Transfer Agreement is terminated*".

#### Conflicts of Interest
The Initial Purchaser, the Sole Structuring Agent and their respective affiliates are financial institutions, (re)insurance companies or (re)insurance intermediaries engaged, or expected to be engaged in the future, in various activities, which may include insurance and reinsurance, insurance and reinsurance related brokerage, securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities.

GEM is a non-profit foundation whose governing board members consist of various companies in the insurance industry, including affiliates of the Initial Purchaser, the Sole Structuring Agent and AIR. Each governing board member of GEM has voting rights, has access to and may provide scientific feedback on earthquake models developed by GEM. Any of the Initial Purchaser, the Sole Structuring Agent and AIR may engage in transactions with GEM on transactions other than the Notes. GEM also collaborates as a partner in scientific research projects with the Primary Earthquake Reporting Agency and the Back-up Earthquake Reporting Agencies.

Certain of the Initial Purchaser and/or the Sole Structuring Agent and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory, investment banking, insurance and reinsurance and insurance and reinsurance related brokerage services for ADB for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the Initial Purchaser, the Sole Structuring Agent and any of their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own accounts and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve securities and instruments of ADB, including the Notes.

#### There may be conflicts of interest relating to the Initial Purchaser's and the Sole Structuring Agent's (and their respective affiliates') business activities.
Various potential and actual conflicts of interest may arise as a result of the insurance and reinsurance, insurance and reinsurance related brokerage, securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage services, and any other services, provided by the Initial Purchaser, the Sole Structuring Agent and any of their respective affiliates to ADB and others, as well as in connection with the investment, trading and brokerage activities of the Initial Purchaser, the Sole Structuring Agent and any of their respective affiliates. The following briefly summarizes some of these conflicts, but is not intended to be an exhaustive list of all such conflicts.

The Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates may from time to time hold the Notes for investment, trading or other purposes, and may enter into derivatives, risk transfer agreements or other financial instruments relating to or referencing the Notes. As a result of such transactions or arrangements, the Initial Purchaser, the Sole Structuring Agent and any of their respective affiliates may have interests adverse to those of ADB and the Noteholders.

------

Furthermore, in the course of providing insurance and reinsurance or insurance or reinsurance related brokerage services, or any other services, the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates may become privy to the output of alternative risk models which may differ, possibly materially, from the output reflected in the Earthquake Expert Risk Analysis Report.

If the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates becomes a Noteholder, through market-making activity or otherwise, any actions that it takes in its capacity as a Noteholder, including voting, providing consents or otherwise, will not necessarily be aligned with the interests of other Noteholders. To the extent the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates makes a market in the Notes (which they are under no obligation to do), they would expect to receive income from the spreads between their bid and offer prices for the Notes. In connection with any such activity, they will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions and activities based on the potential effect on an investor in the Notes. The price at which the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates may be willing to purchase the Notes, if they make a market, will depend on market conditions and other relevant factors and may be significantly lower than the Issue Price for the Notes and significantly lower than the price at which they may be willing to sell the Notes.

No investment in the Notes by the Initial Purchaser, the Sole Structuring Agent or any of their respective affiliates should be regarded as a recommendation to invest in any Notes. Any decisions to invest in the Notes should be based solely on the investor's own evaluation of its financial circumstances, investment objectives, risk tolerance, liquidity needs, regulatory status and any other factors that it deems relevant.

#### Regulatory Risks

#### ADB is not regulated by any regulatory authority.
ADB is not licensed or authorized under any current securities, commodities, insurance or banking laws of any jurisdiction and has not applied (and does not expect to apply) for any such licenses or authorizations. There can be no assurance, however, that regulatory authorities in one or more jurisdictions would not take a contrary view regarding the applicability of any such laws to ADB. The taking of a contrary view by any such regulatory authority could have an adverse impact on ADB or the Noteholders.

#### Significant aspects of the tax treatment of the Notes are uncertain.
You should consider the tax consequences of investing in the Notes, significant aspects of which are uncertain. See "*Taxation*" at page PS-50 in this Prospectus Supplement.

#### THE ISSUER
ADB is an international organization established in 1966 and owned by its 69 members. Under Strategy 2030, which sets the direction for ADB to respond effectively to the changing needs of Asia and the Pacific, ADB continues to sustain its efforts to achieve a prosperous, inclusive, resilient, and sustainable Asia and the Pacific. In its Strategy 2030 Midterm Review, ADB approved an ambitious new road map to guide its evolution and scale up its support on key challenges facing Asia and the Pacific. ADB assists its members and partners by providing loans, technical assistance, grants, guarantees, and equity investments to promote social and economic development.

ADB was founded mainly to act as a financial intermediary to transfer resources from global capital markets to developing member countries for economic development. Its ability to intermediate funds from global capital markets for lending to its developing members is an important element in achieving its development missions.

------

#### USE OF PROCEEDS
The net proceeds to ADB from the sale of Notes will be included in the ordinary capital resources of ADB and used in its ordinary operations.

------

#### THE RISK TRANSFER TRANSACTION
ADB is issuing the Notes in order to support its obligation to make certain payments to the Country under the Risk Transfer Agreement upon the occurrence of one or more Applicable Events during the Risk Period.

#### Kyrgyz Republic
The Kyrgyz Republic, as a part of its disaster risk financing strategy, is seeking to enter into the Risk Transfer Agreement to mitigate the effects of earthquakes and extreme precipitation for vulnerable persons in the Country, where the severity of such events could potentially exceed its financial capacity.

Specifically, the Country is seeking to enter into the Risk Transfer Agreement with the following primary objectives:

<br> • Complement its financial and risk management strategy in relation to the costs and fiscal strain imposed by the effects of natural catastrophes; and

<br> • Reduce the fiscal burden associated with the rising impact of climate change, strengthen fiscal resilience, grow and enhance social safety nets and enhance infrastructure resilience.

Further, the Country intends to use any proceeds disbursed under the Risk Transfer Agreement to finance emergency responses in accordance with the laws and procedures of the Country. Under the Risk Transfer Agreement, the Country agreed that payments it receives from ADB upon a Principal Reduction shall be paid to vulnerable persons in the Country in accordance with standard operating procedures acceptable to ADB and adopted prior to issue of the Notes.

The Country has no obligations under, and does not guarantee, any of the Notes.

Information relating to the Country has been provided to ADB by the Ministry of Finance of the Kyrgyz Republic and has not been independently verified by ADB.

#### The Risk Transfer Agreement
On or prior to the Issue Date, ADB will enter into the Risk Transfer Agreement with the Country.

#### Payments
Under the Risk Transfer Agreement, the Country is required to pay ADB as follows:

On the Issue Date of the Notes, the Country will pay to ADB a premium payment equal to the aggregate amount of Daily Interest Amount calculated based on the Risk Margin that ADB would have to pay with respect to the Notes on each Specified Interest Payment Date through (and including) the last Specified Interest Payment Date, assuming that no Principal Reduction occurs with respect to the Notes, *provided*, that, the Country and ADB agreed in the Risk Transfer Agreement and the DRB Grant Agreement that the proceeds from the resources of the Asian Development Fund, which is a Special Fund of ADB, in respect of this transaction (the "**DRB Grant Funds**") will be applied to the payment described above due thereunder, and the Country shall cause the DRB Grant Funds to be applied to payment of such amounts and the receipt by ADB of any such amounts will discharge, by an equal amount, the Country's obligation to pay the amounts described above due thereunder. The Country remains liable for all other amounts.

Under the Risk Transfer Agreement, following each Principal Reduction Date, ADB will pay to the Country an amount equal to the Principal Reduction (if any) that occurred on such Principal Reduction Date. Under certain circumstances, the Country may request that ADB expedite such payment (reduced by a financing charge for expediting such payment).

------

#### Procedures relating to Notices
Under the Risk Transfer Agreement, during the Risk Period and from time to time, the Country may provide ADB with a notice of potential Earthquake Event, a notice of potential extension of maturity, a notice of election not to further extend maturity, a notice of potential Reporting Agency Failure Event, a notice of potential error in an Event Report or a notice of potential Event Calculation Agent Failure Event. Upon receipt of any such notice, ADB may, at its sole discretion, (i) provide a notice relating to the subject matter described in such notice to the applicable Event Calculation Agent and/or other applicable parties or (ii) engage in discussions with the Country relating to such notice. Until the Country and ADB agree on the approach with respect to the subject matter described in such notice, ADB will be under no obligation to provide any notice relating thereto to any person. In addition, ADB may, at its sole discretion, but under no obligation, provide a Notice of Earthquake Event, an Extension Notice, a notice of election not to further extend maturity, a notice of Reporting Agency Failure Event, a notice of error in an Event Report or a notice of Event Calculation Agent Failure Event to the applicable Event Calculation Agent and/or other applicable parties, in each case without first receiving a notice from the Country.

#### Payments under Risk Transfer Agreements; Standard Operating Procedures
Under the Risk Transfer Agreement, the Country shall ensure that any and all Aggregate Event Payment Amounts (as defined in the Risk Transfer Agreement) and Expedited Payments (as defined in the Risk Transfer Agreement) it receives from ADB are paid to vulnerable persons in accordance with standard operating procedures acceptable to ADB and adopted prior to issue of the Notes (the "**Standard Operating Procedures**"). The Standard Operating Procedures shall leverage existing social protection systems and provide timely and accountable transfer procedures for payment of such amounts, including clear processes for monitoring, reporting and internal controls to safeguard the integrity of the payments. ADB shall retain the right to request a financial audit of the payments made by the Country from Aggregate Event Payment Amounts (as defined in the Risk Transfer Agreement) and Expedited Payments (as defined in the Risk Transfer Agreement) and the Country shall enable ADB's representatives to inspect any relevant records and documents.

If and to the extent any Aggregate Event Payment Amount or any Expedited Payment is paid to the Country under the Risk Transfer Agreement and subsequently the Country discloses to ADB information relating to the disbursements made to vulnerable persons in accordance with the Standard Operating Procedures, then ADB will use commercially reasonable efforts to make available to the Noteholders a report on such disbursements through the Site in substantially the form of Annex III to Attachment A.

There is no contractual obligation in the Notes for the Country to apply any payments received under the Risk Transfer Agreement in accordance with the Standard Operating Procedures or for the Country or ADB to provide reports or other information on the application of such payments following an Applicable Event. The failure of the Country to apply any payments received under the Risk Transfer Agreement in accordance with the Standard Operating Procedures will not constitute a breach of any covenant in the Notes or an event of default under the Notes. The Standard Operating Procedures, and any reports or disclosures associated with the Standard Operating Procedures, are not incorporated into this Prospectus Supplement.

#### Change of Law
If the Country or ADB determines that a "Change of Law", as defined in the Risk Transfer Agreement, has occurred and is continuing, it may elect to terminate the Risk Transfer Agreement by giving written notice to the other party. Any such election will give rise to a Mandatory Redemption Event with respect to the Notes. See "*Overview—The Notes—Maturity and Extension; Redemption Terms—Risk Transfer Termination Event*" and "*Additional Risk Factors—The Notes may be redeemed before the Scheduled Maturity Date, including in circumstances where the Risk Transfer Agreement is terminated*".

Under the Risk Transfer Agreement, "Change of Law" will mean:

(i) with respect to ADB (in which case ADB will be the "**Affected Party**"): (x) a termination of ADB's operations pursuant to Chapter VII, Article 45 of the Agreement Establishing the Asian Development Bank, or (y) any amendment to, change in or the issuance of, laws of the Country (including a change in, or the issuance of, any official interpretation, guidance or application thereof), which becomes effective after the date of the Risk Transfer Agreement, and that upon becoming effective would materially and adversely impair ADB's ability to perform or would result in material adverse consequences or materially increase the regulatory burden for ADB if it continued to perform its obligations under the Risk Transfer Agreement, in each case as determined by ADB following written advice of counsel (with a copy provided to the Country); and

(ii) (ii) with respect to the Country (in which case the Country will be the "Affected Party"): any amendment to, change in or the issuance of, laws of the Country (including a change in, or the issuance of, any official interpretation, guidance or application thereof), which becomes effective after the date of the Risk Transfer Agreement, and that upon becoming effective would materially and adversely impair the Country's ability to receive the benefit of any payment required to be paid to it by ADB under the Risk Transfer Agreement, as determined by the Country following written advice of counsel (with a copy provided to ADB).

#### Risk Transfer Termination
If a "Risk Transfer Termination Event", as defined in the Risk Transfer Agreement, occurs and is continuing with respect to a party (the "Affected Party"), the other party may elect to terminate the Risk Transfer Agreement by written notice to the Affected Party. Any such election will give rise to a Mandatory Redemption Event with respect to the Notes. See "*Overview—The Notes—Maturity and Extension; Redemption Terms—Risk Transfer Termination Event*" and "*Additional Risk Factors—The Notes may be redeemed before the Scheduled Maturity Date, including in circumstances where the Risk Transfer Agreement is terminated*".

Under the Risk Transfer Agreement, a "Risk Transfer Termination Event" with respect to each of the Country and ADB will occur if:

(i) such party fails to pay, when due, any amount required to be paid by it to the other party under the Risk Transfer Agreement, if such failure is not remedied within five (5) Business Days after notice of such failure is given to it by the other party;

<br> (ii) a representation of such party under Section 8.01 of the Risk Transfer Agreement proves to have been incorrect or misleading in any material respect when made; or

(iii) such party (a) materially breaches the Risk Transfer Agreement in a manner that can be cured and fails to cure such breach within thirty (30) calendar days after notice thereof has been provided to it by the other party or (b) materially breaches the Risk Transfer Agreement in a manner that cannot be cured.

#### Mandatory Early Termination
If (i) a Full Mandatory Redemption Event occurs with respect to the Notes or, (ii) after a Redemption Amount Payment Date, the Outstanding Nominal Amount of Notes equals zero (0), then the Risk Transfer Agreement will terminate on the fifth (5th) Business Day following the applicable Redemption Amount Payment Date.

If an Extension Event occurs with respect to the Notes, the term of the Risk Transfer Agreement will be automatically extended to the date that is five (5) Business Days following the relevant Extended Maturity Date on which the Notes become due and payable.

#### TAXATION

#### United States Federal Income Tax Treatment
The following is a general description of certain United States federal income tax considerations to a U.S. Holder (as defined in the accompanying Prospectus) that holds the Notes. This summary supplements the section "*Tax Matters*" in the accompanying Prospectus and is subject to the limitations and exceptions set forth therein. The following applies to you if you are a U.S. Holder, you purchase the Notes in the initial offering, and you hold your Notes as a capital asset for tax purposes. This summary is based upon the law as in effect on the date of this Prospectus Supplement and is subject to any change in law that may take effect after such date.

**No statutory, judicial or administrative authority directly discusses how the Notes should be treated for United States federal income tax purposes. As a result, the United States federal income tax consequences of your investment in the Notes are highly uncertain and alternative characterizations are possible. Accordingly, we urge you to consult your tax advisor in determining the tax consequences of an investment in the Notes, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.**

#### Treatment as an Investment Unit
The treatment of the Notes for United States federal income tax purposes is uncertain. It would be reasonable to treat the Notes as an investment unit consisting of (i) a non-contingent debt instrument that is issued for the Aggregate Nominal Amount of the Notes bearing interest at a rate of Compounded SOFR *plus* the Funding Margin (the "**Debt Portion**") and (ii) a derivative contract in respect of potential Applicable Events that we enter into with you under which we will make payments to you equal to the applicable Risk Margin (including any payments of the Residual Interest Amount) in exchange for your agreement to make payments to us in respect an Applicable Event (the "**Contract**"). The Issuer intends to treat the Notes in this manner, and the discussion below assumes that the Notes will be so treated, except as otherwise specifically noted.

Amounts treated as interest on the Debt Portion would be includible by you in ordinary income in accordance with your regular method of accounting for interest for United States federal income tax purposes. Amounts treated as payments for the Contract would likely be deferred and accounted for upon the sale, redemption or maturity of the Notes or upon the occurrence of an Applicable Event in the manner described below.

If the Outstanding Nominal Amount of your Note is reduced by a Principal Reduction as a result of an Applicable Event, you will be deemed to have used a portion of the principal of the Debt Portion to make a payment to ADB under the Contract with respect to that Applicable Event. Although it is not entirely clear whether and to what extent you could recognize a loss if the Outstanding Nominal Amount of your Note is reduced by a Principal Reduction during the term of the Note, we believe it is reasonable for you to recognize a loss in such a case to the extent of the excess of the relevant Principal Reduction over the *sum* of the Contract payments you have previously received in respect of the Note and the maximum amount of Contract payments (if any) you may receive in respect of the Note if you hold your Note until maturity. It is, however, possible that you would be permitted to recognize a loss in respect of the excess of the Principal Reduction over the *sum* of the Contract payments you have previously received in respect of the Note, without taking into account possible future Contract payments. Please consult your tax advisor regarding such possibility and regarding the United States federal income tax treatment of such loss in general.

A payment received upon a redemption or the maturity of the Notes should be treated as (i) a payment of the Outstanding Nominal Amount of the Debt Portion (which would likely not result in the recognition of gain or loss) and (ii) a final settlement of the Contract, which would result in your recognition of gain or loss in an amount equal to the *difference* between (x) the *sum* of (a) the portion of the stated interest payments on your Notes that is treated as attributable to the Contract that have been deferred as described above and (b) the amount of any loss you have previously recognized for tax purposes in respect of the Contract as a result of an Applicable Event and (y) the *sum* of all Principal Reductions (if any).

Upon a sale of the Notes, you would be required to apportion the value of the amount you receive between the Debt Portion and the Contract on the basis of the values thereof on the date of the redemption or sale. You would recognize gain or loss with respect to the Debt Portion in an amount equal to the difference between (i) the amount apportioned to the Debt Portion (minus any amount attributable to accrued but unpaid interest, which would be taxable as such) and (ii) your adjusted United States federal income tax basis in the Debt Portion (which would generally be equal to the Outstanding Nominal Amount). Such gain or loss in respect of the Debt Portion should be long-term capital gain or loss if your holding period in your Notes is greater than one year. Long-term capital gain of a noncorporate U.S. Holder is generally taxed at preferential rates.

------

If the value of the Debt Portion upon the sale of your Notes is in excess of the amount you receive upon such sale, you would likely be treated as having made a payment to the purchaser equal to the amount of such excess in order to extinguish your rights and obligations under the Contract. You should recognize gain or loss in respect of the Contract in an amount equal to the *difference* between (i) the *sum* of (a) the portion of the stated interest payments on your Notes that is treated as attributable to the Contract that have been deferred as described above, (b) the amount of any loss you have previously recognized for tax purposes in respect of the Contract as a result of an Applicable Event and (c) any portion of the sale proceeds that is attributable to the Contract, and (ii) the *sum* of (a) any amount that you are deemed to pay to the purchaser of the Notes in order to extinguish your rights and obligations under the Contract and (b) the *sum* of all Principal Reductions (if any).

It is unclear whether the character of any gain or loss that you would recognize in respect of the Contract upon the redemption or maturity of the Notes should be ordinary income or loss, short-term capital gain or loss (even if your holding period in your Note is greater than one year) or long-term capital gain or loss (if your holding period in your Note is greater than one year). In addition, it is unclear whether the character of any gain or loss that you would recognize in respect of the Contract upon a sale of a Note should be short-term capital gain or loss (even if your holding period in your Note is greater than one year) or long-term capital gain or loss (if your holding period in your Note is greater than one year). The deductibility of ordinary or capital losses may be subject to limitations. We urge you to consult your tax advisor regarding the character of any gain or loss that you recognize in respect of the Contract.

#### Alternative Characterizations
It is possible that the Notes could be treated as a single debt instrument subject to the special tax rules governing contingent debt instruments. If the Notes are so treated, you would be required to accrue interest income over the term of your Notes based upon the yield at which we would issue a non-contingent fixed-rate debt instrument with other terms and conditions similar to your Notes. In addition, you would be required to compute a projected payment schedule for the Notes, and you would be required to include ordinary income or loss in an amount equal to the difference between the projected amount of the payments on your Notes and the actual payments on your Notes. You would recognize gain or loss upon the sale or maturity of your Notes in an amount equal to the difference, if any, between the amount you receive at such time and your adjusted basis in the Notes.

Alternatively, you may be required to include the entire amount of the stated interest on your Notes (including the portion attributable to the Risk Margin) in ordinary income at the time that such interest is paid or accrued in accordance with your regular method of accounting for United States federal income tax purposes. There are other possible alternative treatments of your Notes and we urge you to consult your tax advisor as to the tax consequences to you of any such alternative treatments of your Notes.

#### Information with Respect to Foreign Financial Assets
Owners of "specified foreign financial assets" with an aggregate value in excess of U.S.$50,000 (and in some circumstances, a higher threshold) may be required to file an information report with respect to such assets with their tax returns. "Specified foreign financial assets" may include financial accounts maintained by foreign financial institutions (which may include the Notes), as well as the following, but only if they are held for investment and not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-United States persons, (ii) financial instruments and contracts that have non-United States issuers or counterparties, and (iii) interests in foreign entities. Holders should consult their tax advisors regarding the application of this reporting obligation to their ownership of the Notes.

#### Medicare Tax
A U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax (the "**Medicare tax**") on the lesser of (1) the U.S. Holder's "net investment income" (or "undistributed net investment income" in the case of an estate or trust) for the relevant taxable year and (2) the excess of the U.S. Holder's modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals is between U.S.$125,000 and U.S.$250,000, depending on the individual's circumstances). A U.S. Holder's net investment income will generally include any income or gain in respect of the Debt Portion and the Contract and its net gains from the disposition of Notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a U.S. Holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the Notes.

------

#### BENEFIT PLAN INVESTOR CONSIDERATIONS
A fiduciary of a pension, profit-sharing or other employee benefit plan subject to the U.S. Employee Retirement Income Security Act of 1974, as amended ("**ERISA**") (each, a "**Plan**"), should consider the fiduciary standards of ERISA in the context of the Plan's particular circumstances before authorizing an investment in the Notes. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the Plan, and whether the investment would involve a prohibited transaction under ERISA or the U.S. Internal Revenue Code (the "**Code**").

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

The acquisition and holding of the Notes by a Plan or any entity whose underlying assets include "plan assets" by reason of any Plan's investment in the entity (a "**Plan Asset Entity**") with respect to which the Issuer, the Calculation Agent, the Registrar and Paying Agent, any Initial Purchaser or any of their respective affiliates is or becomes a party in interest or disqualified person may result in a prohibited transaction under ERISA or Section 4975 of the Code, unless the Notes are acquired and held pursuant to an applicable exemption. The U.S. Department of Labor has issued prohibited transaction class exemptions, or "PTCEs", that may provide exemptive relief if required for direct or indirect prohibited transactions that may arise from the purchase or holding of the Notes. These exemptions include PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 95-60 (for transactions involving certain insurance company general accounts), and PTCE 96-23 (for transactions managed by in-house asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide an exemption for the purchase and sale of the Notes; *provided*, that neither the issuer of the Notes nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction and, if the Issuer, the Calculation Agent, the Registrar and Paying Agent, any Initial Purchaser or any of their respective affiliates is a "party in interest" to a Plan involved in the transaction, it is solely by reason of providing services to the Plan or having a relationship to a service provider to the Plan, and provided further that the Plan pays no more and receives no less than "adequate consideration" in connection with the transaction (the "**Service Provider Exemption**"). There can be no assurance that all of the conditions of any such exemptions will be satisfied.

Any purchaser or holder of the Notes or any interest therein will be deemed to have represented by its purchase and holding of the Notes or any interest therein that it either (1) is not a Plan, a Plan Asset Entity or a Non-ERISA Arrangement and is not purchasing the Notes on behalf of or with the assets of any Plan, a Plan Asset Entity or Non-ERISA Arrangement or (2) the purchase and holding of the Notes will not constitute a non-exempt prohibited transaction under ERISA or the Code or a similar violation under any applicable Similar Laws.

Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is important that fiduciaries or other persons considering purchasing the Notes on behalf of or with the assets of any Plan, a Plan Asset Entity or Non-ERISA Arrangement consult with their counsel regarding the availability of exemptive relief under any of the PTCEs listed above, the Service Provider Exemption or the potential consequences of any purchase or holding under Similar Laws, as applicable. Neither this discussion nor anything in this Prospectus Supplement is or is intended to be investment advice directed at any potential purchaser that is a Plan, Plan Asset Entity or Non-ERISA Arrangement, or at such purchasers and holders generally, and such purchasers and holders should consult and rely on their counsel and advisors as to whether an investment in the Notes is suitable and consistent with ERISA, the Code and any Similar Laws, as applicable. Purchasers of the Notes have exclusive responsibility for ensuring that their purchase and holding of the Notes do not violate the fiduciary or prohibited transaction rules of ERISA or the Code or any similar provisions of Similar Laws. The sale of any Notes to a Plan, Plan Asset Entity or Non-ERISA Arrangement is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Plans, Plan Asset Entities or Non-ERISA Arrangements generally or any particular Plan, Plan Asset Entity or Non-ERISA Arrangement or that such investment is appropriate for such Plans, Plan Asset Entities or Non-ERISA Arrangements generally or any particular Plan, Plan Asset Entity or Non-ERISA Arrangement.

#### PLAN OF DISTRIBUTION
The Initial Purchaser has agreed, subject to the terms and conditions of the Terms Agreement dated 23 April 2026, entered into between the Initial Purchaser and ADB, to purchase from ADB (and ADB has agreed to sell to the Initial Purchaser) the principal amount of Notes specified on the cover page.

The purchase price of the Notes payable by the Initial Purchaser represents the Issue Price of 100% of the Aggregate Nominal Amount thereof. Under the terms and conditions of the Terms Agreement, the Initial Purchaser is committed to purchase and pay for U.S.$80,000,000 Aggregate Nominal Amount of the Notes when offered by ADB. The fees and commissions of the Initial Purchaser, as well as costs and expenses relating to the offering of the Notes, are payable by ADB. ADB will be reimbursed for all such fees and commissions, as well as certain other offering-related expenses, from the proceeds of DRB Grant Funds and other grant funding relating to the offering of the Notes.

The Initial Purchaser may purchase the Notes for its own accounts and for the accounts of its affiliates, if applicable.

The Initial Purchaser and any of its affiliates may from time to time hold Notes for investment, trading or other purposes.

The Initial Purchaser will agree to offer and sell the Notes at the Issue Price only to investors who, among other things, (i) are Qualified Institutional Buyers, (ii) are residents of, and purchasing in, and will hold the Notes in, a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction and (iii) otherwise agree to be bound by the transfer restrictions described under "*Notice to Investors*" herein. The Notes may be reoffered and sold only to investors who (i) are Qualified Institutional Buyers, (ii) are residents of, and purchasing in, a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction, (iii) in Singapore, are institutional investors or accredited investors as defined under Section 4A of the SFA and (iv) otherwise agree to be bound by the transfer restrictions described under "*Notice to Investors*" herein.

After the Notes are released for sale in the public, the offering prices and other selling terms may from time to time be varied by the Initial Purchaser. In the future, the Initial Purchaser and any of its affiliates may repurchase and resell the offered Notes in market-making transactions, with resales being made at prices related to prevailing market prices at the time of resale or at negotiated prices.

As part of their regular business, the Initial Purchaser and any of its affiliates may also provide investment banking, commercial banking, asset management, commodity pool operator and financing and financial advisory services and products, insurance and reinsurance, insurance and reinsurance related brokerage to the Issuer and its affiliates, and purchase, hold and sell, both for their respective accounts or for the account of their respective clients, on a principal or agency basis, loans, securities, and other obligations and financial instruments and engage in private equity investment activities. Neither the Initial Purchaser nor any of its affiliates will be restricted in their performance of any such services or in the types of debt or equity investments that they may make. In conducting the foregoing activities, they will be acting for their own account or the account of their customers and will have no obligation to act in the interest of ADB.

Sales by Aon Securities may be made by, through or on behalf of Aon Securities LLC and its appropriately licensed affiliates, including Aon Solutions (Ireland) Limited ("**ASIL**"). For investors in certain European Union countries, ASIL may act as a selling agent in connection with its distribution in those countries in the European Union. ASIL, which has a registered address of Iveagh Court, 6 Harcourt Road, Dublin 2, D02 VH94, is a company authorized and regulated by the Central Bank of Ireland ("**CBI**") with reference number C29118. The Prospectus and this Prospectus Supplement are not intended for retail clients.

Furthermore, ADB may, from time to time, directly or indirectly own equity or debt of the Initial Purchaser or one or more of its affiliates. The Initial Purchaser or any of its affiliates may purchase the Notes for its own account and for the accounts of its affiliates.

ADB expects that delivery of the Notes will be made against payment therefor on or about 30 April 2026, which will be on or about the fifth (5th) business day following the Trade Date (this settlement cycle being referred to as "T+5"). Trades in the secondary market generally settle on the next business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the Trade Date or the next three (3) succeeding business days will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on the Trade Date or the next three (3) succeeding business days should consult their own advisor.

------

The Notes are a new issue of securities with no established trading market. ADB has been advised by the Initial Purchaser that they intend to make a market in the Notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes.

Settlement for the Notes will be made in immediately available funds.

No action has been or will be taken by ADB, the Initial Purchaser or any broker-dealer affiliates of the Initial Purchaser that would permit a public offering of the Notes or possession or distribution of this Prospectus Supplement or the accompanying Prospectus in any jurisdiction where action for that purpose is required. No offers, sales or deliveries of the Notes, or distribution of this Prospectus Supplement or the accompanying Prospectus, may be made in or from any jurisdiction except in circumstances which will result in compliance with any applicable laws and regulations and will not impose any obligations on ADB, the Initial Purchaser or any broker-dealer affiliates of either ADB or the Initial Purchaser.

------

#### NOTICE TO INVESTORS
*Because of the following restrictions, investors are advised to consult legal counsel before making any purchase, offer, resale, pledge or other transfer of the Notes.*

The Notes are exempted securities under the Securities Act, and therefore the Notes have not been and will not be registered under the Securities Act. Notwithstanding the exemption from the registration requirements under the Securities Act, the Notes are being offered and sold only to, and may be reoffered, sold or otherwise transferred only to, investors who (i) are Qualified Institutional Buyers and (ii) are residents of, and purchasing in, and will hold the Notes in, a Permitted U.S. Jurisdiction or a Permitted Non-U.S. Jurisdiction.

Each purchaser of the Notes must comply with all applicable laws and regulations in force in any jurisdiction in which it purchases, offers or sells Notes or possesses or distributes this Prospectus Supplement or any part of it and must obtain any consent, approval or permission required by such purchaser for the purchase, offer or sale by such purchaser of Notes under the laws and regulations in force in any jurisdiction to which it is subject or in which it makes such purchases, offers or sales, and none of ADB, the Initial Purchaser, the Sole Structuring Agent, the Global Agent or any of their respective officers, directors, agents or affiliates will have any responsibility therefor.

#### Insurance Laws
Because the Notes may be categorized as risk-linked securities, it is possible that in some jurisdictions, purchasers of the Notes may become subject to regulation as providers of insurance or reinsurance.

#### Euroclear Actions with Respect to the Notes
The Global Agent will request that Euroclear include the risk-linked securities ("**RLS**") descriptor in its securities database in order to indicate that sales are limited to purchasers who are residents of and purchasing in, and will hold the Notes in, Permitted U.S. Jurisdictions or Permitted Non-U.S. Jurisdictions and that the RLS restrictions will be further explained in the New Issues Acceptance Guide.

#### Clearstream Actions with Respect to the Notes
The Global Agent will direct Clearstream to reference "RLS" in the security name as it appears in the Clearstream securities database in order to indicate that sales are limited to purchasers who are residents of and purchasing in, and will hold the Notes in, Permitted U.S. Jurisdictions or Permitted Non-U.S. Jurisdictions.

#### Bloomberg Screens, Etc.
ADB will from time to time request applicable third-party vendors to include on screens maintained by such vendors appropriate legends regarding risk-linked securities restrictions on the Notes. Without limiting the foregoing, the Initial Purchaser will request that Bloomberg, L.P. include the following on each Bloomberg screen containing information about the Notes at the bottom of the "Security Display" page describing the Notes: "GRLS. SEE OM—ONLY QIB/PERMITTED JURISDICTIONS."

#### Legends
The Issuer will not remove the legend set forth below in "—*Representations of Purchasers*" at any time.

The Issuer has engaged the Global Earthquake Model Foundation ("GEM"), as an independent consultant, to estimate the rates of occurrence of earthquakes affecting the Republic of Tajikistan and the Kyrgyz Republic. GEM's work includes estimating potential earthquakes, their probabilities of occurrence within specified time intervals, their geophysical characteristics, and their effects on populations and buildings in the region.

GEM is a non-profit, public-private organization founded in 2009, based in Pavia, Italy. GEM develops seismic hazard and risk models for regions worldwide, as well as datasets and software to perform probabilistic seismic hazard and risk assessment.

To estimate the probabilities of earthquake occurrences affecting the Republic of Tajikistan and the Kyrgyz Republic, GEM has created a Probabilistic Seismic Hazard Analysis (PSHA) model for the broader Central Asia region (Version 2025.0). This is created with GEM's model building tools and is run with the OpenQuake Engine, GEM's state-of-the-art probabilistic seismic hazard and risk analysis modeling program. The PSHA model defines the annual occurrence rates for a comprehensive set of millions of plausible earthquakes in the region. <br>

This GEM Expert Hazard Analysis document describes the data and methods used by GEM on behalf of the Issuer to calculate the estimated distribution of losses. The data modeling and explanations included in the "*GEM Expert Hazard Analysis*" section have been prepared by GEM as experts in such matters.

| **2** | **Seismic Hazard Modeling Approach** |

---

Though insurers and reinsurers often rely on standard actuarial practices to estimate future losses based on those in the past, for certain types of catastrophic events including earthquakes, this approach is insufficient. Damaging earthquakes occur relatively infrequently in a given area, so that knowledge of past events (perhaps decades or centuries ago) is often poor; and in many regions with complex geology, a wide variety of such earthquakes is possible, so that the next damaging event is unlikely to resemble the previous events.

Calculating the expected earthquake losses in this complex and uncertain environment requires a different approach, one that uses a comprehensive range of unique possible earthquakes and their effects, and estimates of the frequencies of occurrence of each. The set of possible earthquakes and their occurrence rates is constructed systematically from a broad range of geological and geophysical data, calibrated to instrumentally–observed seismic catalogs, and compared to historical events. The potential losses are estimated based on high-resolution datasets of exposed assets, which are each linked to determinations of the probable damage levels they would sustain, based on the intensity of the earthquake-induced ground shaking. The seismic ground motions emanating from each potential earthquake are estimated through a suite of published empirically calibrated models that account for the characteristics of the earthquake, the distance between the earthquake and the site of an individual or group of assets, the nature of the geologic crust in the area, and the soil conditions at the site.

&nbsp;&nbsp;&nbsp;&nbsp;**2.1** **Limitations of Seismic Hazard and Risk Analysis Included Herein** 

The results of GEM's analyses are not to be viewed as facts or forecasts of future Earthquake Events and should not be relied upon as a representation of the future values of the Notes. Actual earthquake occurrence can materially differ from that generated by the GEM model. No model of catastrophe events is, or can be, an exact representation of reality. The earthquake occurrences and other analyses generated by GEM are based on assumptions relating to environmental and other factors, many of which represent subjective judgements, are inherently uncertain, and are beyond GEM's control. Accordingly, the hazard analysis produced by the GEM Model is subject to uncertainty. The assumptions and methodologies used by GEM may not constitute the exclusive set of reasonable assumptions and methodologies, and the use of alternative assumptions and/or methodologies could yield results materially different from those generated by GEM.

In its hazard estimation models for earthquakes, and in the development of various parameters used in the GEM Model, GEM has relied on published technical papers, historical catalogs of past events, scientific theory published in refereed journals, and other data and analyses that it believes represent the current and credible scientific opinion as of their respective release dates. GEM has not reviewed, however, the authenticity of all the data in the historical catalogs as to the dates, locations, or severities of the catastrophe events. Further uncertainties arise from insufficient data, limited scientific knowledge, alternative theories governing empirical relationships, and the random nature of earthquakes.

A-E-I-2

------

GEM reviews its modeling assumptions on a regular basis in light of new seismological, engineering, and other data and information, and refines its hazard estimates as such information becomes available. Such refinements materially alter, and have in the past materially altered, the hazard estimates generated by the GEM Model.

&nbsp;&nbsp;&nbsp;&nbsp;**2.2** **Scientific Terms and Concepts** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.1** **Earthquakes: definition and occurrence** 

An *earthquake* is the sudden release of stored elastic strain energy in the Earth's crust or upper mantle. Most earthquakes occur when a *fault* (a fracture or plane of weakness in the Earth along which differential motion of the rock on either side has occurred) abruptly slips or ruptures, and there is rapid relative movement of the rock to either side. This sudden motion creates seismic waves that radiate outward from the source. These waves cause the Earth's surface to shake as they pass, which is the proximate cause of damage. A fault is said to be *active* (i.e. capable of generating an earthquake) if it has hosted earthquakes in the past 10,000–100,000 years, or if the rocks to either side of it are measurably moving.

The *magnitude* describes the earthquake's size at its source and is intended to be comparable across regions and recording conditions. Modern practice typically uses moment magnitude (*M<sub>w</sub>*), which is based on seismic moment, a physical measure proportional to the area of the fault that slipped, the average slip on that area, and the rigidity of rock. Because it reflects the total rupture size and slip, *M<sub>w</sub>* is a more consistent measure for large earthquakes than older magnitude scales. A one–unit increase in *M<sub>w</sub>* corresponds to roughly a 32–fold increase in energy release (approximately), so small changes in magnitude imply large changes in the potential for damaging shaking.

The *intensity* of the *ground motion* (shaking) depends on the characteristics of the earthquake (e.g., the magnitude or amount of energy release, the depth and location, size and shape of the earthquake rupture, the relative sense of displacement); the travel path between the earthquake rupture and the site of interest (the distance of travel, the stiffness of the rock); and the soil conditions at the site (the depth and stiffness of the soil).

The location of an earthquake is often expressed using the latitude, longitude, and depth of the *hypocenter*, the point from which the rupture originates. The *epicenter* is the vertical projection to the topographic surface of the *hypocenter*.

The Earth's outer shell (the lithosphere) is broken into tectonic plates that move slowly, primarily driven by convection in the planet's interior. The plates are generally internally rigid, but deform at and near their boundaries, primarily due to the forces of adjacent plates, as well as the gravitational stresses that result from variations in crustal thickness, elevation, and density. This deformation leads to pervasive fracturing of the cold outer lithosphere; as slivers of crust move past each other along faults, the edges of the crustal slivers or blocks stick because they are frictionally locked together, elastically shearing the crust until sufficient energy has accumulated to overcome the friction, and the fault slips in an earthquake.

A-E-I-3

------

The rates of motion of the crustal blocks or slivers are reasonably constant over thousands of years. These are the *slip rates* of the intervening faults, and they are proportional to the rates of seismic energy release on the faults. Fault slip rates range from about 0.1 mm/yr for the slowest– moving faults in seismically active areas, to tens of mm/yr for the most rapid plate–boundary faults such as the Main Himalayan Thrust fault near the region of interest. These rates are measurable through field geological investigations and through analysis of Global Positioning System (GPS) and other satellite geodetic data. The measured slip rates of faults may then be used to estimate seismic occurrence rates on the faults.

In areas of pervasive faulting and frequent seismicity, the lithosphere is heavily damaged and relatively hot, causing strong attenuation of seismic energy as waves travel through it. In contrast, the interiors of tectonic plates, away from active faults, are colder, stiffer, and less fractured; seismic waves travel with less dissipation in these tectonically stable areas. Therefore, the ground motion intensity from an otherwise identical earthquake at a given distance will be less in an area of active faulting than in a stable region. The depth of an earthquake also plays a strong role in the intensities of its ground motions; deeper events have longer paths to sites on the surface, so they have less intense ground motions (especially at the frequencies that cause damage to single–story buildings), even though a site may be quite close on a map to the *epicenter*. Deep seismicity is frequent in and around the southern part of the Republic of Tajikistan (Figure 2).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.2** **Uncertainties in hazard and risk models** 

Virtually everything in science is subject to some amount of uncertainty: values are not capable of being measured with absolute accuracy and precision, and indeed may change through time or have some inherent randomness. Scientific concepts are also often imperfectly defined, due to a lack of knowledge or incompletenesses and incompatibilities in scientific theory. This is the nature of advancing knowledge.

Seismic hazard models are built on data (subject to measurement uncertainty) and scientific theory (with its own limitations), and also model a fundamentally random process, that of earthquake occurrence. These different sources of uncertainty can be classified into two groups, which are treated differently in the hazard and risk modeling process.

The first type of uncertainty is 'aleatory uncertainty', which is the natural, random variability within a system or process. A familiar example is the value of the next roll of a fair, six–sided die. There is no way to predict the specific value, but we know that all values between 1 and 6 are equally possible. *Aleatory uncertainty is irreducible.* No amount of additional knowledge or constraints can decrease or remove it. Earthquake occurrence is subject to significant aleatory uncertainty: the numbers and magnitudes of earthquakes that occur each year vary, even though the fundamental processes that govern earthquake occurrence may not, and this is not an artefact of our imperfect knowledge of the system, due to either observational or theoretical limitations.

The second type of uncertainty is 'epistemic uncertainty', which *is* a reflection of our imperfect knowledge of the system. This can be either uncertainty in the specific value of something (due to challenges in measurement, for example) or to known gaps in theory. Epistemic uncertainties are, in principle, reducible by the addition of information. To continue the dice analogy, if we do not know how many sides an *n*-sided die is, or if it is fair or not, then we have epistemic uncertainty in the distribution of possible outcomes—this is distinct from the aleatory uncertainty in the *next* roll. In seismic hazard and risk models, there are many sources of epistemic uncertainty: the slip rates of individual faults, the magnitude–frequency distribution of those faults, potential interactions between the faults, the characteristics of attenuation of ground shaking from each potential earthquake, the numbers and types of buildings and other infrastructure in the area, the fragility of those assets, how people are affected by those damages.

A-E-I-4

------

The two types of uncertainty are handled differently within seismic hazard and risk models. The most fundamental aleatory uncertainty is the random variability in earthquake occurrence. This is primarily accounted for by producing stochastic event sets, in which the randomness is modeled with statistical tools for describing this variability, such as the Poisson temporal occurrence model, which specifies the expected variability around the mean occurrence rate over different time periods, given certain assumptions. Other aleatory uncertainties, for example randomness in ground motions or in asset damage given a specific level of ground shaking, are handled similarly with appropriate statistical distributions. These statistical distributions are essentially built into the model and modeling package; i.e., they are implicit, and expressed through sampling during the modeling process.

Epistemic uncertainties, on the other hand, are generally handled through separate computational paths for each component that has associated epistemic uncertainty (regardless of whether those uncertainties are best described by discrete or continuous variables), through a logic tree structure. This allows for wide flexibility in alternative specifications, and makes explicit the sources of and choices for the representation of epistemic uncertainty. The cost of this is computational complexity: Given *n* independent sources of epistemic uncertainty represented by *m* branches per source, the total number of possible logic tree paths is *n<sup>m</sup>*.<br>

It should be noted that, from the standpoint of an observer, there is an interplay between the aleatory and epistemic uncertainties of an unknown quantity. If one observes only the outcomes of a few rolls of a die, they may not know whether the die has 5 or 6 sides, or whether it is fair. The same is true of seismic hazard and risk modeling: the modelers must bring to bear a set of noisy data and incomplete scientific theory to infer the rates and consequences of earthquakes, such that both the aleatory and epistemic uncertainties are accurately represented.

A third type of uncertainty is 'parametric uncertainty', which is essentially a choice of model parameters that do not truly relate to a lack of knowledge but of modeling considerations. These parameters may not describe some natural quantity subject to epistemic uncertainty, but instead some factor in the construction or operation of the model. An example would be the spacing of points representing the Earth's surface, where hazard is calculated. When these factors can affect model behaviour, a suite of them may be used in different branches of a logic tree, just as would be done with epistemic uncertainties; however they are philosophically different.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.3** **Seismotectonics of Central Asia** 

Tectonics and seismicity in Central Asia are driven by the convergence of the Eurasian plate in the north with the Indian and Arabian plates in the south (Figure 1). The crust of the southern margin of Eurasia, including the Iranian and Tibetan plateaus and the mountain belts of the Pamir and Tien Shan ranges, is pervasively faulted and undergoes distributed deformation throughout, leading to seismicity throughout the area (Figure 2).

Within and around the Kyrgyz Republic and the Republic of Tajikistan, seismicity is most active along the boundary between the Tien Shan and Pamir ranges, in a belt through northern Tajikistan. The belt of seismicity extends to the east into Xinjiang province, China, southeast of the Kyrgyz border but close enough to potentially cause shaking near the border (though this mountainous area is sparsely populated). To the south, in the Pamir range, crustal seismicity is most present along a strike–slip fault running through the Pamir, which hosted the 1911 and 2017 Sarez earthquakes, both with an *M<sub>w</sub>* of around 7.3.

------

Seismicity in the Tien Shan region, which encompasses the Kyrgyz Republic and northern Republic of Tajikistan, is distributed throughout. Though it is less frequent than along the Pamir–Tien Shan belt, magnitudes can be large. The Tien Shan contains many distributed reverse faults that individually slip fairly slowly (rates of 0.1–2 mm/yr, generally). Because faults are highly interconnected, very large earthquakes can occur during multifault ruptures. An example is the 1911 Chon-Kemin earthquake south of Almaty, Kazakhstan, with a magnitude of around *M<sub>w</sub>* 8.0. However, a very large strike–slip fault, the Talas–Ferghana fault, bisects the Kyrgyz Republic. It has generated large earthquakes in the past, and the 1946 Chatkal (*M<sub>w</sub>* estimated at 7.5) is widely thought to have occurred on this fault.

An additional, globally notable region of deep seismicity (with large earthquakes extending to hundreds of km depth) exists in the Pamir and Hindu Kush in and east of the southern Republic of Tajikistan. Though earthquakes in this zone can be very large, the largest are deep enough that they are not particularly damaging though they are widely felt. This deep seismicity is generally considered to be related to the subduction of lithosphere of the Indian plate into the Eurasian mantle.

&nbsp;&nbsp;&nbsp;&nbsp;**2.3** **Hazard Model Construction** 

The GEM Central Asia seismic hazard source model is constructed as a combination of fault sources and distributed seismicity sources. The geometry of fault sources is based on mapping, and seismicity occurrence rates are determined by inverting geodetic and geologic data. The distributed seismicity sources are made from an instrumental seismic catalog. Fault and distributed seismicity sources are combined in a second stage, with spatial and magnitude intersections (potentially duplicating seismicity) resolved. All uncertainties in the seismic source model are aleatory, though the ground motion component (not described in this report) also contains epistemic uncertainty. The inclusion of epistemic uncertainties in the source model is a potential avenue for future investigation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.1** **Data Sources** 

The Central Asia (CEA) hazard source model is a synthesis of various data sources that serve as proxies for future seismicity.

Fault sources were built from GIS–based mapping by GEM, as part of a global active fault remapping effort. Faults are mapped and determined to be potentially active based primarily on tectonic geomorphology (that is, the interpretation of the topographic surface, satellite imagery, and rock units), seismic and geodetic information, and previous maps and other research. Validation of the mapping in the study area was performed by field geologists at the University of Oxford who have been working in the region, as part of a longer-term collaboration with GEM. The subsurface fault geometries (e.g., dip angle and termination at depth of the fault) are inferred from the fault kinematics, geologic deformation, and regional seismicity if information for a particular fault is not available. The faults were mapped with the primary goal of seismic hazard modeling, so the geometries and inclusion criteria are most suited for this purpose, in contrast to many existing databases compiled for scientific study, which are often too fine, too coarse, or otherwise incomplete and unsuitable. Furthermore, the faults were drafted under the assumption that multifault rupture creation would be possible in the source model creation, so fault segmentation naturally follows the expression of the faults in the source datasets rather than the limitations of the modeling program.

A-E-I-8

------

The slip rates on the faults (which control the accumulation of seismic energy) are determined by inverting geodetic and geologic deformation data using an elastic block model, as described below. The inversion uses 3859 satellite geodetic velocities, which are a mix of GNSS (GPS) data from a wide range of published sources as well as velocities derived from satellite interferometry (InSAR) by the University of Leeds, provided to GEM as part of a long–term collaboration. The inversion also uses 78 geological fault slip-rate measurements, taken from the literature.

An instrumental seismic catalog is used to build the distributed seismicity and to verify the full hazard source model against observations of seismic occurrence. We have used the GEM Global Earthquake Catalog which is constructed by merging the ISC-GEM v10, GCMT, and ANSS Com-cat catalogs; duplicate events were removed through automated and manual methods. As classical PSHA models are typically 'time–independent', i.e. representing only mainshocks without additional conditional earthquake occurrence, the catalog is 'declustered' to remove foreshocks and aftershocks. We used the Gardener and Knopoff approach with the parameters proposed by Urham-mer; two alternative sets of parameters were tested, namely, the Gardner–Knopoff and Gruental ones. With these settings, declustering removes slightly more events but does not yield substantive differences in the rates or spatial distributions of damaging seismicity, so including alternative catalogs brings no real benefit but adds computational expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.2** **Geodetic-Geologic Block Model** 

Fault slip rates were determined from an elastic block model which inverts geologic and geodetic data to estimate the motions of crustal blocks in the region, and the slip rates of intervening faults. Block modeling is a well–established geoscience technique, building off of the fundamental mathematics of plate tectonics. Essentially, blocks are coherent bodies of the Earth's crust that are bound by faults or non-fault deforming zones (generally not seismically expressive). The instantaneous motion of any block can be described as a rotation around an 'Euler pole' or pole of rotation located at some position on the Earth. As no natural reference frame for global block motion exists, all rotations are relative to some arbitrary or convenient reference frame. The slip rate of a fault is the relative motion between adjacent blocks at the fault location.

Blocks were mapped in QGIS at the same time as fault mapping. This allows for maximum compatibility between the faults and blocks and optimizes the geometry of each. The blocks were drawn so that they encompass the maximum amount of similar geodetic data available while still honoring the geometries of the faults and accounting for natural changes in rate along strike of a fault or due to branching or other complexities. Generally, blocks within a deforming zone have a handful of geodetic data in each, while the large tectonic plates surrounding the region (e.g., the Indian or Arabian plates) have hundreds or thousands.

The block modeling itself was performed using Oiler, GEM's program created for the purpose, written in the Julia scientific computing language. Oiler assembles a system of equations for the motion of each block relative to the reference frame for each geodetic vector or geologic slip rate.

A-E-I-9

------

The equations account for the effects of fault locking on the geodetic deformation field, but this does not affect the geologic slip rates. The system of equations is augmented by plate circuit constraints that ensure that the relative motion between any three plates is consistent regardless of the reference frame or basis of comparison, and then given additional regularization in the form of damping of velocities that prevent spurious solutions in underconstrained regions. The global system of equations is sparse, and solved through a weighted linear least squares solution using *LU* factorization using the SuiteSparse solvers. Once the system of equations is factorized, the global optimal solution is found. Then, uncertainties in the results are found through a Monte Carlo approach: the data vector is perturbed hundreds or thousands of times by sampling each data point from its uncertainty distribution, and then the factorized system is iteratively solved. This produces a robust propagation of data uncertainties into the solution, which is then propagated into the uncertainties for the fault slip rates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.3** **Fault Source Construction** 

Fault sources are created from fault information as described in the previous sections using GEM's tool Fermi for fault network rupture modeling, which yields faults that are capable of subfault ruptures (which involve a section of the fault surface) to multifault ruptures (in which single–fault ruptures on multiple faults rupture jointly). The fault surfaces are the same as those in the mapping and block model, i.e. there is no additional simplification of the fault geometries. The fault surfaces are first broken up into subfaults of equal dimensions, targeting 10 x 10 km. These subfaults are the smallest independent sources of fault ruptures on the fault system, producing ruptures about *M<sub>w</sub>* 6.0. Then, larger ruptures are formed on each fault by assembling all contiguous, rectangular sets of subfaults that either a) have realistic aspect ratios (i.e., with a minimum along–strike width to down–dip length ratio of just under one and a maximum of 3), or b) fully saturate the down–dip extent of the fault, in which case there is no maximum aspect ratio. The minimum magnitude of rupture for a given fault is the smallest subfault, and the maximum magnitude is the largest multifault rupture that a fault participates in. Therefore, these parameters are determined through the fault network configuration and geometry, rather than imposed directly.

Once all of the single–fault ruptures have been created, multifault ruptures are found. First, all of the pairs faults that are within a specified maximum separation or 'jump distance' of 10 km are identified. From these pairs, an adjacency graph is created. Then, all possible multifault ruptures are enumerated through a depth–first search on the adjacency graph, with a maximum number of single–fault ruptures in an individual multifault rupture. For a regional model like the GEM CEA model, only full–fault ruptures are allowed to participate in multifault ruptures, otherwise, billions of ruptures would be created, which is overly computationally demanding without adding much realism. After the ruptures are created, a score for the geometric and kinematic plausibility of each is calculated, and the rupture set is stochastically filtered proportionally to the plausibility.

In the CEA model, 485 faults were included in the hazard model. These were broken into 9387 subfaults. About 74,000 single–fault and 10,000 multi-fault ruptures were included in the model after plausibility filtering.

Once the rupture set has been selected, the annual occurrence rates for each rupture are determined through an inversion of geological and seismological constraints. Inversion seeks to match the slip rates for each subfault (Figure 3), as well as matching a *b*-value of 0.8 on each subfault; this is calibrated to match the regional seismicity rates and magnitude–frequency distribution (though a model–wide magnitude–frequency distribution was not imposed for this model). This calibration indicated that a seismic slip rate fraction (the component of fault slip that is released in earthquakes modeled on the faults) is 1.0.

**Figure 3:** Comparison between observed and modeled slip rates on the various faults within the investigated area. Observed slip rates are in black, with error bars shown on the *y* axis. The modeled slip rates are shown in blue. The diagonal black line indicates a 1:1 relationship (i.e., a perfect fit).

The rupture rate inversion creates a system of linear equations that is solved in a weighted, non–negative least squares sense using a simulated annealing solver. The constraints are fit quite well, especially the slip rates (which are virtually all within 1-σ uncertainty, Figure 3) and the match to the regional seismicity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.4** **Distributed Seismicity Sources Construction** 

The distributed seismicity sources represent seismicity not linked to mapped faults, and to moderate magnitude seismicity both near and far from faults. The distributed seismicity sources are modelled as multipoint sources, i.e. gridded points with *b*-values set for the source and variable *a*-values. There are 13 crustal distributed seismicity sources in the CEA model (Figure 4). They were created from a larger set covering all of Asia, then trimmed to a buffer of about 300 km around the Central Asian nations.

The seismicity rates within each distributed seismicity source are based on the earthquakes in the GEM Global Earthquake Catalog that fall within its boundary. For each source, the completeness window (within which it is assumed that no earthquakes are missing) is found for different magnitude ranges, as well as the Gutenberg–Richter *a*- and *b*-values, using the Weichert method. Then, the rates of seismicity at each grid point in the source are found by a kernel–based smoothing of the instrumental, declustered seismicity, and then balancing the point rates to sum to the source's total seismicity rate.

The distributed sources belong to different 'tectonic regions' each one corresponding to a set of ground motion models used to compute the median shaking and its uncertainty for each considered rupture. Sources within the actively faulted and deforming regions are given an 'Active Shallow Crust' type, which has higher attenuation; sources in the more rigid areas are given 'Stable Continental' designations.

A-E-I-12

------

After the distributed sources have been made, 3D buffers are created around the faults at a distance of 20 km. Any point source within this buffer has all of its ruptures ≥ *M<sub>w</sub>* 6.0 removed, as that seismicity is modeled by the fault sources. This avoids 'double counting' the observed on–fault earthquakes.

Two sources were made for the deep seismicity in the region. These are made in a similar way to the crustal sources.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.5** **Stochastic Event Set Generation** 

A 100,000-year stochastic event set is generated by first calculating the annual occurrence rates for all earthquake ruptures permitted by the seismic source model and converting those rates into annual probabilities of occurrence. Earthquake occurrences are then simulated over a 100,000-year time horizon, assuming a Poisson process, by randomly sampling the number and year-of-occurrence of events for each rupture. This random sampling continues until the full 100,000-year synthetic catalogue is produced, yielding a large ensemble of events whose long-term frequency and characteristics are statistically consistent with the input occurrence rates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.4** **Seismic Source Model Validation** 

The seismic source model is validated using GEM's program Hamlet (Hazard Model Evaluation and Testing). Hamlet provides a comprehensive set of tests (in which a criterion is tied to a pass/fail threshold) and evaluations (in which a qualitative or quantitative criterion is applied but not in a pass/fail sense). Because the fundamental challenge of seismic hazard assessment is that the period of comprehensive instrumental seismic observations is far less than the return period for the damaging earthquakes we seek to model, most of the tests are based around the generation of stochastic event sets (i.e., set of earthquakes representing one potential realization of the seismicity admitted for the source model during a predefined period of time, say 10,000 years) of the same duration as the seismic observations, and the statistical comparisons of the two. Although the full results are not shown here, those of primary importance are shown and discussed herein. Perhaps the most important component of validation is that the model is capable of reproducing the observed seismic catalog, both in its gross statistical attributes and in its particulars. Figure 5 shows that the observed magnitude–frequency distribution is within the range of stochastic simulations of the period of observation. Figure 6 shows the results of the *M*-Test, which looks more specifically at the earthquake occurrence within magnitude bins, and it is clear that the observed number of earthquakes within each bin is consistent with the model.

Though the aggregate statistics of earthquake occurrence show the model matching the observations on net, those comparisons do not address whether there are spatial discrepancies in observed vs. modeled seismicity. To evaluate this, we perform the *S*-test, which evaluates the number of earthquakes produced in hexagonal grid cells of 10s of km across, and compares the number of observed events to the number produced in synthetic catalogs. The results are shown in Figure 7. The high likelihood of each of the hundreds of hexagonal cells indicates that the spatial occurrences of modeled seismicity are highly compatible with the observations. This is especially significant because the majority of the seismicity in the model is produced by fault sources, whose activity rates are not calibrated to the spatial distribution of the seismic catalog. Additional testing (not shown) verifies that each earthquake above *M<sub>w</sub>* 6.0 in the catalog within the hazard model can be well–represented by a rupture in the model.

#### Historical Analysis

Figure 3 and Table 9 together provide information on historical Earthquakes for the Notes. The epicenter, magnitude, and depth parameters of the historical Earthquake Events shown in the figures below are based on the latest available information reported since the event occurrence as of the last update to the GEM Model unless otherwise stated. It is reasonable to conclude that the further back in time an Earthquake Event took place, there is potential for increased uncertainty in the parameters reported and used for this analysis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The epicenter location, magnitude and depth parameters of the historical Earthquake Events shown in the table are based on GEM's historical earthquake analysis for Central Asia from
 1885 – 2025, using source data selected in accordance with a defined source hierarchy and event-specific expert judgment. For Earthquake Events occurring from 2008 to 2025, GEM generally relied on the Primary
 Reporting Agency; for Earthquake Events occurring from 1904 to 2008, GEM generally relied on the ISC-GEM Catalogue v12.1; and for Earthquake Events occurring prior to 1904, GEM relied on recent published studies
 where available and otherwise on the GEM Global Historical Earthquake Catalogue, in each case subject to event-specific expert judgment if deemed necessary. It is reasonable to conclude that the further back in time
 an Earthquake Event took place, there is potential for increased uncertainty in the parameters reported and used for this analysis.

#### Probability of the Notes and Tajikistan Notes Triggering from the same Earthquake Event

#### <br>
The Earthquake Covered Area of the Notes and the earthquake covered area under the terms and conditions of a separate series of notes that relates to certain earthquake and extreme precipitation perils of the Tajikistan (the "**Tajikistan Notes**") and is issued by ADB on or around the issue date of the Notes are overlapping and cover the same boxes in the northern part of the Tajikistan and the southern part of the Country. An Earthquake occurring within such area of overlapping could trigger one or both of the Notes and/or the Tajikistan Notes. GEM has conducted an analysis of the probability of triggering the Notes and the Tajikistan Notes from the same simulated Earthquake. Table 10 provides information on the conditional probability of earthquake events triggering of the Notes and/or the Tajikistan Notes. For the Notes and the Tajikistan Notes, the probability of an event triggering the Tajikistan Notes given that the Notes have triggered is **7.5**% and the probability of an event triggering the Notes given that the Tajikistan Notes have triggered is **7.4**%. Table 11 provides information on the contribution to modeled expected loss for the Notes and the Tajikistan Notes from earthquake boxes that contribute to modeled expected losses for both notes. The contribution to modeled expected loss for the Tajikistan Notes from boxes that also contribute to the modeled expected loss for the Notes is 24.1% and the contribution to modeled expected loss for the Notes from boxes that also contribute to modelled expected loss for the Tajikistan Notes is 8.9%. Figure 4 shows the spatial relationship between the Earthquake Box Locations of both notes. Figure 4 illustrates that while both notes share a relatively broad band of 112 overlapping boxes along the border region (56 shallow boxes and 56 deep boxes), only a smaller subset of 14 of those overlapping boxes (13 shallow boxes and 1 deep box) contributes to modeled expected losses in both notes. The annotated Minimum Magnitude Conditions further indicate that, even within the 14 shared boxes, the payout response can differ materially between the two notes because the Notes and Tajikistan Notes apply different Minimum Magnitude Conditions for the same Earthquake Box Location.

**APPENDIX P-I**

#### METHODOLOGY FOR DETERMINING AN EXTREME PRECIPITATION EVENT

#### <br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Overview** 

An Extreme Precipitation Event will be determined by reference to quantification of the severity of prolonged (21-day) rainfall events, accounting explicitly for rain-on-snow and snowmelt effects, over the Country, based on ERA5 reanalysis data on a fixed latitude/longitude grid.

The methodology for Extreme Precipitation combines:

• **Meteorological intensity:** 21-day accumulated snow-adjusted rainfall

• **Spatial aggregation:** 3x3 neighbourhood sums to represent mesoscale footprint

• **Extreme classification:** grid-cell-specific quantile thresholds

• **Exposure weighting:** population fractions and terrain (slope) adjustment

The Extreme Precipitation Event Calculation Agent will execute calculation daily for a rolling 21-day window.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Data inputs** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.1.** **ERA5 meteorology (dynamic inputs)** 

ERA5 is a global atmospheric reanalysis dataset from the European Centre for Medium-Range Weather Forecasts (<u>ECMWF</u>) on behalf of the Copernicus Climate Change Service. Reanalysis combines model output with observations through data assimilation to generate a globally complete, physically consistent dataset of atmospheric and land-surface variables at hourly temporal resolution and 0.25° spatial resolution, from 1940 to near-present. The ERA5 dataset used for this index is updated daily with a typical latency of around five days (the ERA5T "early release"), enabling both historical analysis and near-real-time monitoring applications.

Although ERA5 is available from 1940 onwards, ERA5 was published from 1980 with data from weather satellites. Accordingly, information included in the Extreme Precipitation Data File use ERA5 data from 1980 and onwards.

Hourly ERA5T single-level meteorological fields are retrieved for a fixed spatial domain and aggregated to daily values for use in the determination for Extreme Precipitation Event.

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Downloaded**<br> **ERA5T data** | **Temporal**<br> **resolution** | **Units (downloaded)** | **Processing /** <br> **aggregation** | **Units (processed)** |
| Total precipitation (tp) | Hourly | metres (m) per hour (liquid water equivalent) | Daily sum | millimetres per day (mm/day) |
| Snowfall (sf) | Hourly | metres (m) per hour (water equivalent) | Daily sum | millimetres per day (mm/day, water equivalent) |
| 2-metre air temperature (t2m) | Hourly | Kelvin (K) | Daily mean | degrees Celsius (°C) |

---

ERA5T data are extracted for a fixed bounding box covering the Country:

• North: 43.75°N

• West: 68.75°E

• South: 38.75°N

• East: 80.75°E

These daily gridded fields provide the meteorological basis for rain-only screening, snow-melt adjustment, rolling accumulation, and spatial aggregation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.** **Static grid metadata (static inputs)** 

A precomputed grid dataset provides per-cell parameters which is available in the Extreme Precipitation Data File in the "GRID_DATA" tab which includes:

<br> • grid identifiers and coordinates (grid_id, latitude, longitude),

<br> • grid-cell-specific extreme quantile thresholds for snow-adjusted rainfall (Q1/Q2),

<br> • country flags (KGZ),

<br> • population fraction per grid cell,

<br> • a terrain modifier based on median slope intensity, and

A-P-I-1

------

<br> • neighbourhood definitions for 3x3 relationships in respect of a central grid cell (i.e. the Extreme Precipitation Location) and eight neighbouring cells.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Rain-only screening** 

To ensure snowfall is not treated as liquid rainfall, a rain-only daily rainfall series is first derived for each grid cell. This step removes precipitation falling as snow and excludes low temperature days where rainfall is not expected to contribute directly to runoff as follows:

• Daily snowfall is subtracted from total precipitation.

<br> • Resulting rainfall values are constrained to be non-negative.

<br> • If daily mean temperature is equal or below 1°C, the rain-only value is set to zero.

This rain-only series provides the base input for the snow-melt adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Snow-melt uplift (dynamic adjustment)** 

The snow-melt adjustment accounts for situations where rainfall coincides with an existing snowpack under warming conditions, increasing effective runoff. The adjustment is applied after rain-only screening and before rolling accumulation.

The adjustment is calculated by date only and applied uniformly across all grid cells for that day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.1.** **Seasonal snow context** 

Seasonal snow conditions are represented using November to March winter snow climatology, within the grid cells of the Country identified in the Extreme Precipitation Data File, which captures the accumulation of winter snowfall relevant for subsequent spring snow-melt processes. For each calculation date, a normalised seasonal snow value is taken from the corresponding November to March winter period, providing a measure of how snowy the preceding winter was relative to typical conditions and, therefore, the amount of snow available for melt. For the avoidance of doubt, such seasonal value is calculated only once for the season if the data is completed for the immediately preceding period from November to March and will not be updated thereafter.

The normalised seasonal snow factor is calculated by scaling each November to March seasonal snowfall total relative to the maximum November to March snowfall observed over the historical record used in the analysis. For the purposes of this transaction, the reference (peak) season is 2010, which represents the highest winter snowfall total in the ERA5 record for the relevant region with a value of 117.4 m. As a result, the normalised seasonal snow factor is not capped at 1.0 and may exceed 1.0 in the event that a future winter season records snowfall in excess of the 2010 reference level.

For the first operational season under this Agreement, the normalised seasonal snowfall value ![](image00041.jpg) for the November-March 2025-26 winter season is set at 0.7334 and shall apply throughout that season without further update. For future winter seasons, the seasonal snow factor will be updated each April, once data for the full November-March season are available.

![](image1.jpg)

*Figure 1: Seasonal November to March normalised snow values for 1980-2026. The dashed line shows the long-term mean (excluding the incomplete 1980 season).*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.2.** **Seasonal timing factor (April to June only)** 

Snow-melt effects are restricted to the spring and early summer melt season using a month-specific scaling factor ![](image00052.jpg):

A-P-I-2

------

• April: ![](image00052.jpg) = 1.00

• May: ![](image00052.jpg) = 0.75

• June: ![](image00052.jpg) = 0.50

• All other months: ![](image00052.jpg) = 0.00

This prevents snow-melt uplift outside physically plausible periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.3.** **Temperature influence** 

Two temperature-based factors are calculated using rolling 21-day temperature statistics derived from a country-wide spatial mean temperature series. Specifically, for each single day *d*, the temperature inputs are calculated as follows:

<br> 1. For each day, the daily mean 2-metre air temperature is first calculated at each grid cell from hourly ERA5 data.

<br> 2. A single country-level daily mean temperature is then derived as the simple arithmetic mean across all cells within the Extreme Precipitation Covered Area.

<br> 3. Rolling 21-day temperature statistics are then computed from this country-level daily mean temperature series, and the resulting values are applied uniformly to all grid cells for that country on the relevant date.

Using this country-level temperature series, the following quantities are defined:

• ![](image00060.jpg): the 21-day mean temperature over days ![](image00061.jpg) to ![](image00055.jpg); and

• ![](image00062.jpg): the change in 21-day mean temperature relative to the previous 21-day window, defined as

![](image00063.jpg)

These are then converted into bounded factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Mean temperature factor** 

The 21-day mean temperature is scaled and capped:

![](image00064.jpg)

Warmer conditions increase melt influence, up to a maximum value of 1.

The function clip(x, 0, 1) means:

• if ![](image00065.jpg), set it to ![](image00043.jpg);

• if ![](image00044.jpg), keep it as ![](image00045.jpg);

• if ![](image00046.jpg), set it to 1.

Example: if ![](image00066.jpg), then ![](image00047.jpg) and ![](image00048.jpg).

**2.** **Temperature-change factor**

The 21-day temperature change is scaled and capped:

![](image00049.jpg)

Rapid warming increases melt influence, but is deliberately limited to half the strength of the mean-temperature factor.

The function clip(x, 0, 0.5) means:

• if ![](image00065.jpg), set it to ![](image00043.jpg);

• if ![](image00050.jpg), keep it as ![](image00045.jpg);

• if ![](image00051.jpg), set it to ![](image00053.jpg).

Example: if ![](image00054.jpg), then ![](image00067.jpg) and ![](image00068.jpg).

Finally, these factors are combined with the seasonal timing factor ![](image00052.jpg) (April-June only) to produce a melt weight bounded between 0 and 1:

![](image00069.jpg)

where ![](image00070.jpg) indicates no melt influence and ![](image00071.jpg) indicates strong melt influence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.4.** **Snow-melt multiplier** 

The daily snow-melt multiplier is defined as:

![](image00072.jpg)

where:

A-P-I-3

------

• ![](image00073.jpg) is a scaling parameter,

• ![](image00041.jpg) is the normalised seasonal snow value, and

• ![](image00074.jpg) is the daily melt weight.

To avoid unrealistically large uplifts, the multiplier is capped as:

![](image00075.jpg)

where cap = 0.15.

The snow-adjusted daily rainfall is then:

![](image00076.jpg)

where ![](image00077.jpg) is the daily rainfall after rain-only screening has been applied. For avoidance of doubt, such snow-adjustment factor ![](image00078.jpg) is calculated by date only and applied uniformly across all cells for that day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Rolling 21-day accumulation (per grid cell)** 

For each grid cell, snow-adjusted rainfall is accumulated over a rolling 21-day window ending on an Extreme Precipitation Day:

![](image00079.jpg)

Here, ![](image00080.jpg) indexes the number of days prior to the Extreme Precipitation ![](image00055.jpg), such that the summation includes day ![](image00055.jpg) and the preceding 20 calendar days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **Spatial 3x3 neighbourhood aggregation** 

To represent the spatial footprint of prolonged rainfall and reduce sensitivity to single-grid-cell noise, a 3x3 neighbourhood aggregation is applied.

For each Extreme Precipitation Location which is the central grid cell ![](image00081.jpg), a predefined set of neighbouring cells ![](image00082.jpg) is used. The spatially aggregated 21-day snow-adjusted rainfall is defined as:

![](image00083.jpg)

where:

• ![](image00084.jpg) is the 21-day Snow-adjusted Rainfall total for neighbouring cells.

This aggregation ensures that the index responds to coherent, mesoscale rainfall events, rather than isolated single-cell extremes. The aggregated values (the Extreme Precipitation Level) are carried forward to the extreme classification step.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.** **Extreme classification using per-cell quantile thresholds** 

Each Extreme Precipitation Location has precomputed extreme thresholds at two quantiles, ![](image00085.jpg) and ![](image00086.jpg), derived from historical 3x3 aggregated 21-day snow-adjusted rainfall totals.

A contribution factor is assigned for each grid cell as follows:

![](image00087.jpg)

This step converts continuous rainfall magnitudes into discrete severity levels, allowing consistent comparison of events across space and time. Each Extreme Precipitation Location exceeding the lower quantile q1 is an Extreme Precipitation Affected Location contributing to the index value.

Grid-cell-specific quantile thresholds used in the calculation are provided in the Extreme Precipitation Data File.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.** **Exposure weighting and index calculation** 

• **Population weighting**

For the country, each grid cell has an associated population weighting ![](image00088.jpg).

• **Terrain (slope) adjustment**

To account for the influence of terrain on runoff and impact severity e.g. due to higher risk of landslides or mudslides for steeper terrain, a terrain modifier ![](image00089.jpg), derived from median slope, is applied multiplicatively:

This produces an extreme rainfall index contribution for each grid cell.

![](image00090.jpg)

A-P-I-4

------

Grid-cell-specific population weighting and terrain modifiers used in the calculation are provided in the Extreme Precipitation Data File.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9.** **Extreme Precipitation Index Value** 

The Extreme Precipitation Index Value is obtained daily by summing Extreme Precipitation Index Value contributions across all Extreme Precipitation Affected Locations belonging to the Extreme Precipitation Covered Area:

![](image00091.jpg)

In addition to the Extreme Precipitation Index Value, diagnostic outputs include:

<br> • the number of grid cells contributing to the Extreme Precipitation Index Value, and

• the total population at risk in cells exceeding the grid-cell-specific extreme quantile thresholds for Snow-adjusted Daily Rainfall.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.** **Event monitoring and notification framework** 

The Extreme Precipitation Index Value is calculated and monitored on a daily basis throughout the term of the Notes. To support timely awareness of developing events a notification framework is applied based on the daily Extreme Precipitation Index Value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.1.** **Extreme Precipitation Event Period** 

If there is an Extreme Precipitation Affected Location on a Extreme Precipitation Date and such Extreme Precipitation Date is not included in any previously commenced Extreme Precipitation Event Period, a new Extreme Precipitation Event Period (i) starting on the Extreme Precipitation Date and (ii) continuing for the following consecutive twenty (20) calendar days thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.2.** **Notice of Extreme Precipitation Event** 

Within two (2) Business Days after the Extreme Precipitation Event Parameters Date in respect of the first day of such Extreme Precipitation Event Period, a Notice of Extreme Precipitation Event will be provided. This notification indicates that conditions are approaching policy trigger levels and that a potential Extreme Precipitation Event may be developing. At this stage the Notice of Extreme Precipitation Event is provided for informational purposes only.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.3.** **Event Report** 

Following a Notice of Extreme Precipitation Event, an Event Report is issued to (i) confirm whether an Extreme Precipitation Event has or has not occurred and (ii) if an Extreme Precipitation Event is determined to have occurred, specify the Extreme Precipitation Payout Amount and documenting the verified Extreme Precipitation Index Value outcome and supporting analysis within five Business Days after the earlier of (i) the Extreme Precipitation Event Parameters Date in respect of the Extreme Precipitation Date that is last day of the applicable Extreme Precipitation Event Period and (ii) the Extreme Precipitation Event Parameters Date in respect of the Extreme Precipitation Date that is the first day within the applicable Extreme Precipitation Event Period on which the Extreme Precipitation Index Value exceeds the applicable threshold as a result of which an Extreme Precipitation Event occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11.** **Data availability and contingency procedure** 

The live index calculation relies on ERA5 meteorology to provide a consistent set of meteorological inputs, including precipitation, snowfall, and 2-metre air temperature, at hourly temporal resolution. The ERA5T (early release) hourly data is updated daily for use in the Extreme Precipitation Index calculation. ERA5 is updated on a rolling basis via the ERA5T early-release product, with a typical latency of approximately five calendar days. ERA5T enables near-real-time monitoring while maintaining consistency with the historical analysis. For the purposes of the trigger determination is only the ERA5T will be used. Subsequent revisions introduced when final ERA5 is published do not retrospectively change trigger determinations or event reporting.

For live operations, an ERA5T data issue is defined as missing or incomplete data (for example, gaps in the time coordinate or unavailable files) such that the required daily processing window cannot be constructed. If an ERA5T data issue is missing or incomplete, Extreme Precipitation Event Calculation Agent will apply the following operational response to a Potential Reporting Agency Failure:

• Retry period: For the first ten (10) Business Days following identification of an ERA5T outage or incomplete delivery, Extreme Precipitation Event Calculation Agent will retry retrieval of ERA5T data on a daily basis and will not implement fallback during this period.

A-P-I-5

------

<br> • Fallback period: If the data issue persists beyond ten (10) Business Days, the pipeline switches to a contingency data source only to fill the missing daily inputs required to run the index.

Where ERA5T is temporarily unavailable beyond the retry period, NASA GPM IMERG Late Run precipitation data are used as the operational contingency source. IMERG Late Run is a near-real-time, multi-satellite precipitation product with a stated minimum latency of approximately fourteen (14) hours, providing sufficiently timely coverage for live monitoring applications.

IMERG precipitation is re-gridded to the ERA5 0.25° analysis grid using area-weighted aggregation prior to the calculation of rolling precipitation totals and spatial neighbourhood (3x3) sums, ensuring consistency with the pre-computed ERA5 grid structure and thresholds.

Due to the limitations of such alternative data source, the following modifications are required for the index calculation:

The standard "rain-only" screening step (which removes snowfall and applies a temperature gate in 3. "Rain-only screening" above) cannot be applied when using IMERG, because IMERG is a precipitation-only product and does not provide co-located snowfall or 2-metre temperature fields. As a result, rain-only screening is not applied in contingency mode, and IMERG precipitation is treated directly as the rainfall input for the index calculation during the outage period.

A modified approach is also applied to the snow-melt adjustment during contingency operation:

<br> • Static temperature inputs derived from the ERA5 historical climatology are used in place of real-time temperature data in 4.3 "Temperature influence" above for each applicable day where the IMERG data has to be used:

---

| | | |
|:---|:---|:---|
| Month | Average monthly <br> temperature | Average monthly <br> temperature change |
| January | -12.23 | -1.27 |
| February | -11.00 | 1.37 |
| March | -6.52 | 3.51 |
| April | -0.20 | 4.30 |
| May | 5.17 | 3.49 |
| June | 9.16 | 2.77 |
| July | 12.47 | 2.03 |
| August | 12.99 | -0.03 |
| September | 9.58 | -2.72 |
| October | 3.10 | -4.82 |
| November | -3.88 | -4.63 |
| December | -9.76 | -3.82 |

---

• The contingency calculation applies the same ERA5 November to March seasonal normalized snow factor ![](image00041.jpg) derived from available ERA5 climatology if such value was previously derived from the ERA5 data for the applicable season. In the event that ERA5 November to March seasonal snowfall data are unavailable for the applicable season, an average normalised seasonal snow value of 0.7345 is applied. This value is calculated as the mean normalised November to March snowfall across the historical record, excluding the incomplete 1980 season, and is used to preserve methodological continuity until season-specific data become available.

This approach preserves methodological consistency during short-term ERA5T outages while ensuring that live monitoring can continue without interruption.

Below is a historical analysis of the index performance from 1 January 1980 to 31 December 2025.

![](image47.jpg)

#### Worked example: historical triggering event (May 2016, Kyrgyz Republic)

This section provides a worked example illustrating how the index is calculated for a historical event and how it would have resulted in an Extreme Precipitation Event. The example is intended to demonstrate the mechanics of the methodology rather than to reproduce an actual loss outcome.

#### Event overview

---

| | |
|:---|:---|
| **Country** | Kyrgyz Republic |
| **Event period** | 10 May 2016 to 30 May 2016 |
| **Calculation date** | 29 May 2016 |
| **Event description** | Prolonged heavy rainfall during the spring snow-melt season triggered severe flooding and mudflows in southern Kyrgyz Republic, including a destructive mudflows in Batken, Osh and Jalal-Abad regions, resulting in fatalities and infrastructure damage. |

---

Steps 1 to 5 are performed across the full ERA5 grid domain. For presentation purposes, the intermediate calculations are shown for one example grid cell (ID 1051).

#### Step 1: Snow-adjusted daily rainfall
Daily rainfall is first screened to remove snowfall and cold-temperature precipitation. A snow-melt multiplier is then applied based on seasonal snow conditions and temperature.

---

| | |
|:---|:---|
| **Season year** | 2016 |
| **Month weighting** | 0.75 (May) |
| **Mean 21-day temperature (°C)** | 7.02 |
| **Mean 21-day temperature change (°C)** | 1.57 |
| **Melt weight** | 0.645 |
| **Seasonal snow factor** | 0.638 |
| **Snow-melt multiplier** | 1.082 |

---

The resulting snow-adjusted daily rainfall for each grid cell is:

![](image00076.jpg)

Example grid cell:

---

| | |
|:---|:---|
| **Grid ID** | 1051 |
| **Latitude** | 40.50 |
| **Longitude** | 73.00 |
| **Date** | 29/05/2016 |
| **Rainfall (mm)** | 5.07 |
| **Snow-adjusted rainfall (mm)** | 5.49 |

---

A-P-I-7

------

#### Step 2: Rolling 21-day accumulation
Snow-adjusted rainfall (mm) is accumulated over a rolling 21-day window ending on the calculation date *d*.

![](image00079.jpg)

where *k* represents the number of days prior to the calculation date.

Example grid cell 1051 (40.50°N, 73.00°E):

---

| | | |
|:---|:---|:---|
| **date** | **rain_snow_adj_mm** | **snow_adj_21d** |
| 09 May 2016 | 18.30 | 18.30 |
| 10 May 2016 | 17.30 | 35.60 |
| 11 May 2016 | 19.54 | 55.14 |
| 12 May 2016 | 10.62 | 65.76 |
| 13 May 2016 | 3.31 | 69.07 |
| 14 May 2016 | 8.50 | 77.58 |
| 15 May 2016 | 2.20 | 79.78 |
| 16 May 2016 | 17.14 | 96.92 |
| 17 May 2016 | 20.86 | 117.78 |
| 18 May 2016 | 20.54 | 138.32 |
| 19 May 2016 | 1.33 | 139.66 |
| 20 May 2016 | 0.08 | 139.73 |
| 21 May 2016 | 0.00 | 139.73 |
| 22 May 2016 | 0.38 | 140.11 |
| 23 May 2016 | 15.00 | 155.10 |
| 24 May 2016 | 0.08 | 155.18 |
| 25 May 2016 | 0.59 | 155.77 |
| 26 May 2016 | 1.61 | 157.38 |
| 27 May 2016 | 2.56 | 159.93 |
| 28 May 2016 | 12.95 | 172.88 |
| **29 May 2016** | 5.49 | 178.37 |

---

This step captures the effect of sustained wet conditions, rather than short-duration rainfall.

![](image48.jpg)

** 

<br> *Figure 5: Spatial distribution of 21-day snow-adjusted rainfall totals for the period ending 29 May 2016. The example cell (ID: 1051) is highlighted in green.*

#### Step 3: Spatial 3x3 neighbourhood aggregation
To account for spatial coherence, the rolling 21-day totals are aggregated over a 3x3 neighbourhood.

![](image00083.jpg)

A-P-I-8

------

Example 3x3 neighbourhood (09 May 2016 - 29 May 2016):

---

| | | | | |
|:---|:---|:---|:---|:---|
| **grid_id** | **latitude** | **longitude** | **snow_adj_21d** | **snow_adj_21d_3x3** |
| 993 | 40.25 | 72.75 | 202.52 | 1657.63 |
| 994 | 40.25 | 73.00 | 224.73 | 1825.75 |
| 995 | 40.25 | 73.25 | 230.47 | 1972.36 |
| 1050 | 40.50 | 72.75 | 134.28 | 1477.06 |
| **1051** | 40.50 | 73.00 | 178.37 | 1820.92 |
| 1052 | 40.50 | 73.25 | 229.88 | 2032.73 |
| 1107 | 40.75 | 72.75 | 154.04 | 1538.16 |
| 1108 | 40.75 | 73.00 | 207.66 | 1895.53 |
| 1109 | 40.75 | 73.25 | 258.96 | 2033.37 |

---

#### Step 4: Extreme classification
Each grid cell has precomputed extreme thresholds based on historical 3x3 aggregated snow-adjusted rainfall.

For this event, the aggregated value for grid cell 1051 exceeds the lower threshold but does not exceed the upper threshold:

![](image00092.jpg)

• **Lower threshold** ![](image00093.jpg)**:** 1772.9 mm

• **Upper threshold** ![](image00094.jpg)**:** 1853.45 mm

• **Resulting contribution factor** ![](image00095.jpg)**:** 0.5

![](image00008.jpg)

*Figure 6: Location of grid cells contributing to the index on 29 May 2016. Shaded cells indicate grid cells exceeding the snow-adjusted rainfall thresholds.*

#### Step 5: Exposure weighting
The contribution factor is weighted by the population fraction and terrain modifier associated with the grid cell.

Per-cell index contribution:

![](image00090.jpg)

Example index calculation for grid cell 1051 on 29 May 2016:

---

| | |
|:---|:---|
| **Population weighting ![](image00088.jpg)**<br>| 0.0289 |
| **Contribution factor ![](image00095.jpg)** | 0.5 |
| **Terrain modifier ![](image00089.jpg)** | 6.9 |
| **Per-cell impact index ![](image00096.jpg)** | 0.0498 |

---

#### Step 6: Extreme Precipitation Index Value and trigger outcome
Grid-cell contributions are summed across the country to produce the daily extreme precipitation index value:

![](image00091.jpg)

---

| | |
|:---|:---|
| **Extreme Precipitation Index Value** | 2.762 |
| **Contributing cells** | 64 |
| **Trigger threshold** | 0.85 |

---

A-P-I-9

------

#### Outcome:
The extreme precipitation index value on 29 May 2016 **exceeds** the trigger threshold, meaning an Extreme Precipitation Event **would have occurred** for this event.

#### Interpretation
The accompanying diagnostics indicate that 29 May 2016 represents the peak of the event, with the country-level impact index reaching its maximum value during the latter part of May. This peak reflects the cumulative effect of sustained rainfall and snow-melt conditions persisting over already affected areas, combined with higher population and terrain-weighted contributions.

![](image55.jpg)

*Figure 7: Number of daily extreme cells (left) and daily country-level impact index values (right) for Kyrgyz Republic during May 2016.*

Earlier in the event, the index first exceeded the trigger threshold on 16 May, rising to an initial peak on 19 May as a large number of grid cells contributed under widespread wet conditions. Following this early peak, the index temporarily declined around 24 May, before increasing again to the overall peak on 29 May, reflecting renewed rainfall and continued accumulation over already affected and more highly exposed areas.

<br> (2) if a SOFR Index value does not so appear as specified in (1) above, then:

<br> a. if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "SOFR Index Unavailable" provisions; or

For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to "calculation period" shall be replaced with "Observation Period" and the words "that is, 30-, 90-, or 180- calendar days" shall be removed. If the daily SOFR ("**SOFR**<sub>i</sub>") does not so appear for any day, "i" in the Observation Period, SOFR<sub>i</sub> for such day "i" shall be the SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator's Website.

#### Effect of a Benchmark Transition Event:

If ADB determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, ADB will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by ADB pursuant to this section, 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:

<br> (1) will be conclusive and binding absent manifest error;

<br> (2) will be made in the sole discretion of ADB; and

<br> (3) notwithstanding anything to the contrary in the documentation relating to the Notes described herein, shall become effective without consent from the holders of the Notes or any other party.

A-I-2

------

"**Benchmark**" means, initially, SOFR Index; provided that if ADB determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR Index (or the published daily SOFR 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 ADB as of the Benchmark Replacement Date:

<br> (1) the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

<br> (2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

<sup>(3)</sup> the sum of: (a) the alternate rate of interest that has been selected by ADB as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.<br>

"**Benchmark Replacement Adjustment**" means the first alternative set forth in the order below that can be determined by ADB as of the Benchmark Replacement Date:

<sup>(1)</sup> the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;<br>

<br> (2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

<sup>(3)</sup> the spread adjustment (which may be a positive or negative value or zero) that has been selected by ADB giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark (or the daily published component used in the calculation thereof) with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time.<br>

"**Benchmark Replacement Conforming Changes**" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, and other administrative matters) that ADB decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if ADB decides that adoption of any portion of such market practice is not administratively feasible or if ADB determines that no market practice for use of the Benchmark Replacement exists, in such other manner as ADB determines is reasonably necessary).

"**Benchmark Replacement Date**" means the earliest to occur of the following events with respect to the then-current Benchmark (or the daily published component used in the calculation thereof):

<sup>(1)</sup> in the case of clause (1) or (2) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or<br>

<sup>(2)</sup> in the case of clause (3) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the first date on which such Benchmark (or such component) is no longer representative per such statement or publication.<br>

For the avoidance of doubt, if the event that gives 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.

A-I-3

------

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

<sup>(1)</sup> a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or<br>

<sup>(2)</sup> a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark (or such component), the central bank for the currency of the Benchmark (or such component), an insolvency official with jurisdiction over the administrator for the Benchmark (or such component), a resolution authority with jurisdiction over the administrator for the Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark (or such component) has ceased or will cease to provide the Benchmark (or such component) permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or<br>

<sup>(3)</sup> a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing (A) that such Benchmark (or its component) is no longer, or as of a specified future date will no longer be, capable of being representative, or is non-representative, of the underlying market and economic reality that such Benchmark (or its component) is intended to measure as required by applicable law or regulation and as determined by the regulatory supervisor in accordance with applicable law or regulation and (B) that it is being made in the awareness that the statement or publication will engage contractual triggers for fallbacks activated by pre-cessation announcements by such supervisor (howsoever described) in contracts.<br>

"**ISDA Definitions**" means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

"**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 (or the daily published component used in the calculation thereof).

"**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 (or the 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 (or the daily published component used in the calculation thereof) means (1) if the Benchmark is SOFR Index, the SOFR Index Determination Time, and (2) if the Benchmark is not SOFR Index, the time determined by ADB 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.

Attention: Assistant Treasurer, Funding Division

Reference is hereby made to the U.S.$80,000,000 Floating Rate Kyrgyz Republic Disaster Relief Capital at Risk Notes due 30 May 2029 (the "**Notes**"), to be issued by the Asian Development Bank ("**ADB**") and described in the pricing supplement dated as of the date hereof relating thereto (the "**Pricing Supplement**") and the related Prospectus dated 9 December 2020 (the "**Base Prospectus**"), as supplemented by the accompanying Capital at Risk Notes Prospectus Supplement, dated 1 April 2026 (the "**CARN Prospectus Supplement**"), and the Prospectus Supplement, dated as of the date hereof (the "**Notes Prospectus Supplement**"), relating to the Notes (the Base Prospectus, as supplemented by the CARN Prospectus Supplement and the Notes Prospectus Supplement being referred to herein as the "**Prospectus**").

Aon Securities LLC ("**Aon**" or the "**Initial Purchaser**") agrees to purchase from ADB the Notes at 10 a.m. London time on 30 April 2026 (the "**Settlement Date**") at an aggregate purchase price of U.S.$80,000,000 on the terms set forth herein and in the Standard Provisions, dated as of 9 December 2020 (the "**Standard Provisions**"), relating to the issuance of Notes by ADB. The Standard Provisions are incorporated herein by reference. For the avoidance of doubt, solely with respect to the Notes, all references to Prospectus in the Standard Provisions shall mean the Prospectus as defined herein. In so purchasing the Notes, the Initial Purchaser understands and agrees that it is not acting as an agent of ADB in the sale of the Notes.

When used herein and in the Standard Provisions as so incorporated, the term "Notes" refers to the Notes as defined herein. All other terms defined in the Prospectus, the Pricing Supplement relating to the Notes and the Standard Provisions shall have the same meanings when used herein.

ADB represents and warrants to, and agrees with, the Initial Purchaser that the representations and warranties of ADB set forth in Section 2(a) of the Standard Provisions are true and correct as though made at and as of the date hereof and will be true and accurate as though made at and as of the Settlement Date.

------

The Initial Purchaser warrants and covenants that this Terms Agreement has been duly authorized, executed and delivered by it, and that such execution and delivery does not, and the performance by it of its obligations hereunder will not, contravene any provision of applicable law or its articles of association or equivalent constitutive documents or any judgment, order or decree of any governmental body, regulatory agency or court having jurisdiction over it. The Initial Purchaser warrants and covenants to ADB that the warranties of the Dealer set forth in Section 2(b) of the Standard Provisions are true and correct as though made at and as of the date hereof and will be true and accurate as of the Settlement Date.

The obligation of the Initial Purchaser to purchase the Notes hereunder is subject to the continued accuracy, on each date from the date hereof to and including the Settlement Date, of ADB's representations and warranties contained in the Standard Provisions and to ADB's performance and observance of all applicable covenants and agreements contained herein and therein. The obligation of the undersigned to purchase the Notes hereunder is further subject to (a) the additional conditions (if applicable) set forth in Section 6 of the Standard Provisions, including the receipt by the Initial Purchaser of the documents referred to in Section 6(b) and 6(c)(i), (ii) and (vi) of the Standard Provisions, (b) an opinion addressed to the Initial Purchaser from Sullivan & Cromwell LLP, U.S. and English counsel to ADB with respect to the Notes, with respect to the issue and sale of the Notes and other related matters as the Initial Purchaser may reasonably require, and (c) a letter addressed to the Initial Purchaser from Sullivan & Cromwell LLP in customary form addressing the Prospectus, including the documents incorporated by reference therein.

Further, the obligation of the undersigned to purchase the Notes hereunder is subject to the additional condition that, on or after the date hereof, and prior to the time of closing on the Settlement Date, with respect to the Notes, no potential Earthquake or Extreme Precipitation has occurred or is in progress which, in the judgment of the Initial Purchaser, could possibly result in a Principal Reduction with respect to the Notes (including, without limitation, due to any subsequent main shocks or aftershocks reasonably related to such Earthquake).

The obligation of the ADB to issue the Notes hereunder shall be subject to the execution by ADB and the Kyrgyz Republic of the Risk Transfer Agreement relating to the Notes (in form and substance reasonably satisfactory to ADB).

ADB certifies to the Initial Purchaser that, as of the Settlement Date, (i) ADB has performed all of its obligations under the Standard Provisions and this Terms Agreement required to be performed or satisfied on or prior to the Settlement Date and (ii) the Prospectus, as supplemented by the Pricing Supplement, contains all material information relating to the assets and liabilities, financial position, and net income of ADB, and nothing has happened or is expected to happen that would require the Prospectus, as supplemented by the Pricing Supplement, to be further supplemented or updated.

The following additional terms shall apply to the issue and purchase of Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. ADB agrees that it will issue the Notes and the Initial Purchaser agrees to purchase the Notes at the aggregate purchase price specified above (being equal to the issue price of 100.00 per cent. of the
 Aggregate Nominal Amount of the Notes).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Payment for the Notes shall be made on the Settlement Date by the Initial Purchaser to Citibank, N.A., London Branch, for transfer in immediately available funds to an account designated by ADB. Delivery
 of the Notes shall be made to Citibank Europe plc, as common depositary for Euroclear and Clearstream, Luxembourg, for the account of the Initial Purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. ADB hereby appoints Aon as a Dealer under the Standard Provisions solely for the purpose of the issue of the Notes to which this Terms Agreement pertains. The Initial Purchaser shall be vested, solely with respect to this issue of
 Notes, with all authority, right and powers of a Dealer purchasing Notes as principal set out in the Standard Provisions, a copy of which it acknowledges it has received, and this Terms Agreement. The Initial Purchaser acknowledges
 having requested and received, or waived its receipt of, copies of the Prospectus and Global Agency Agreement, duly executed by the parties thereto. In the event of any conflict between terms set forth in the engagement letter between
 ADB and Aon, dated 26 March 2026 (the "**Engagement Letter**") and those set forth in Section 9 of the Standard Provisions with respect to allocation of fees and expenses between ADB and Aon, terms
 set forth in the Engagement Letter shall prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. In consideration of ADB appointing Aon as a Dealer solely with respect to this issue of Notes, Aon hereby undertakes for the benefit of ADB that, in relation to this issue of Notes, it will perform and comply with all of the duties
 and obligations specified to be assumed by a Dealer under the Standard Provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. The Initial Purchaser acknowledges that such appointment is limited to this particular issue of Notes and is not for any other issue of notes of ADB pursuant to the Standard Provisions and that such appointment will terminate upon
 this issue of Notes, but without prejudice to any rights (including, without limitation, any indemnification rights), duties or obligations of the Initial Purchaser that have arisen prior to such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. The Initial Purchaser acknowledges that neither the Pricing Supplement nor the Prospectus has been registered as a prospectus with the Monetary Authority of Singapore ()"**MAS** "). Accordingly,
 the Initial Purchaser represents, warrants and agrees that it has not offered or sold any Notes or caused the Notes to be made the subject of an invitation for subscription or purchase and will not offer or sell any Notes or cause
 the Notes to be made the subject of an invitation for subscription or purchase, and has not circulated or distributed, nor will it circulate or distribute, the Prospectus, Pricing Supplement or any other document or material in
 connection with the offer or sale, or invitation for subscription or purchase, of the Notes, whether directly or indirectly, to any person in Singapore other than (i) to an institutional investor (as defined in Section 4A of the
 Securities and Futures Act 2001 of Singapore, as modified or amended from time to time (the "**SFA** ")) pursuant to Section 274 of the SFA or (ii) to an accredited investor (as defined in Section
 4A of the SFA) pursuant to and in accordance with the conditions specified in Section 275 of the SFA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000 (the "FSMA")) received by it in connection with the issue or sale of the Notes in circumstances in which Section 21(1) of the FSMA does not apply to ADB; and
