(a) (i) Prospectus relating to the Global Medium-Term Note Program dated 9 December 2020, previously filed under a report of the ADB dated 2 February 2021.

(ii) Pricing Supplement dated 26 August 2025.

(b) Copy of an opinion of counsel as to the legality of the Notes (to be filed at a later date).

(ii) Prospectus and Pricing Supplement (see (a) above).

------

**U.K. MiFIR PRODUCT GOVERNANCE / PROFESSIONAL INVESTORS AND ECPs ONLY TARGET MARKET** – Solely for the purposes of each manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook ("**COBS**"), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("**U.K. MiFIR**"); and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a "**distributor**") should take into consideration each manufacturer's target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the "**U.K. MiFIR Product Governance Rules**") is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining each manufacturer's target market assessment) and determining appropriate distribution channels.

ADB does not fall under the scope of application of Directive 2014/65/EU (as amended, "**MiFID II**") or U.K. MiFIR. Consequently, ADB does not qualify as an "investment firm", "manufacturer" or "distributor" for the purposes of either MiFID II or U.K. MiFIR.
