HSBC Holdings PLC had amended the notice of redemption dated April 16, 2026 (the 'Original Notice'). The Original Notice provided that the Issuer will pay interest and principal on the Securities on Monday, May 25, 2026; however, such date is not a Business Day. Accordingly, in accordance with the terms of the Indenture, payment of the interest and principal on the Securities will instead be made on the next succeeding Business Day, being Tuesday, May 26, 2026.

The Securities have been issued pursuant to an indenture dated as of August 26, 2009 (as amended or supplemented from time to time, the 'Base Indenture'), between HSBC Holdings PLC, as issuer (the 'Issuer'), The Bank of New York Mellon, London Branch, as trustee (the 'Trustee'), and HSBC Bank USA, National Association, as paying agent and registrar ('HSBC Bank USA'), as supplemented and amended by a nineteenth supplemental indenture dated as of November 24, 2020 (the 'Nineteenth Supplemental Indenture' and, together with the Base Indenture, the 'Indenture') among the Issuer, the Trustee and HSBC Bank USA as paying agent, registrar and calculation agent. The Issuer has elected to redeem the Securities in whole in accordance with the terms of the Indenture and the Securities (the 'Par Redemption'). Pursuant to Section 11.04 of the Base Indenture and Sections 2.01, 2.02, 3.01, 3.02, 4.01 and 4.02 of the Nineteenth Supplemental Indenture, the Issuer hereby provides notice of the following information relating to the Par Redemption: The redemption date for the Securities shall be May 24, 2026 (the 'Redemption Date').

The redemption price for the Securities shall be USD 1,000 per USD 1,000 principal amount of the Securities (the 'Redemption Price'). Additionally, in accordance with the terms of the Indenture, as the Redemption Date is an Interest Payment Date all accrued but unpaid interest from (and including) November 24, 2025 to (but excluding) the Redemption Date will be payable to the holders of record of the Securities as of May 9, 2026, the Regular Record Date (the 'Interest Payment'). Subject to any conditions and/or the limited circumstances contained in the Nineteenth Supplemental Indenture, on the Redemption Date the Redemption Price and the Interest Payment shall become due and payable upon each such Security to be redeemed and interest thereon shall cease to accrue on and after such date.

Pursuant to the terms of the Indenture, as the Redemption Date is not a Business Day, the Issuer will pay interest and principal on the Securities on the next succeeding Business Day, Tuesday, May 26, 2026. In accordance with the terms of the Indenture, interest on the payment of the Redemption Price and the Interest Payment shall not accrue during the period from and after the scheduled Redemption Date. Securities should be surrendered at the registered office of HSBC Bank USA at 66 Hudson Boulevard East, 545W9, New York, NY 10001, Attention: Issuer Services.

Existing US federal income tax law may require backup withholding of 24% of any payments to holders presenting their Securities for payments who have failed to furnish a taxpayer identification number certified to be correct under penalty of perjury on a complete and valid Internal Revenue Service ('IRS') Form W-9 or applicable Form W-8 to the applicable payer or withholding agent. Holders may also be subject to penalties for failure to provide such number.
