$1,500,000,000 7.325% Fixed Rate Resetting Senior Callable Notes due 2026 (ISIN: US06738ECC75,
CUSIP: 06738E CC7, Common Code: 255286447)*

This notice (the “Notice of Redemption”) is in relation to Barclays PLC’s (the “Company”) $1,500,000,000 7.325% Fixed Rate Resetting Senior Callable Notes due 2026 (the “Notes”).

The Notes were issued pursuant to the Senior Debt Securities Indenture (the “Base Indenture”), dated January 17, 2018, between the Company and The Bank of New York Mellon, London Branch, as Trustee (the “Trustee”), as supplemented by the Thirteenth Supplemental Indenture, dated as of November 2, 2022, among the Company, the Trustee and The Bank of New York Mellon SA/NV, Luxembourg Branch, as Senior Debt Security Registrar (the “Thirteenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). Capitalized terms used herein and not defined herein shall have the meanings ascribed to such terms in the Indenture.

The Company hereby notifies the Holders that it elects to redeem and will redeem the Notes pursuant to Section 11.02 of the Base Indenture and Sections 2.04 and 2.06 of the Thirteenth Supplemental Indenture. Accordingly, the Company has requested that the Trustee provide the Notice of Redemption to all Holders of the Notes.

The outstanding Notes will be redeemed on November 2, 2025 (the “Redemption Date”) at an amount equal to 100% of their principal amount, together with any accrued but unpaid interest from, and including, May 2, 2025 to, but excluding, the Redemption Date (the “Redemption Price”). The Redemption Date is not a business day and, as a result, the payment of principal and interest payable on redemption of the Notes will be made on November 3, 2025, which is the next succeeding business day. Accordingly, the listing of the Notes on the New York Stock Exchange will be cancelled on, or shortly after, November 3, 2025.

The location where Holders may surrender the Notes and obtain payment of the Redemption Price is The Bank of New York Mellon, 160 Queen Victoria Street, London EC4V 4LA, United Kingdom, Attn: Corporate Trust Administration, Email: corpsov1@bnymellon.com, Fax: +44 (0) 20 7964 2536.

On the Redemption Date, the Redemption Price will become due and payable and interest on the Notes will cease to accrue. On or prior to the Redemption Date, the Company will irrevocably deposit with the Trustee or with a Paying Agent an amount of money sufficient to pay the total Redemption Price of each of the Notes. When the Company makes such a deposit, all rights of Holders of the Notes will cease, except the Holders’ rights to receive the Redemption Price, but without interest, and the Notes will no longer be outstanding.
