AIB GROUP PLC

DIRECTORATE CHANGE

AIB Group plc and Allied Irish Banks, p.l.c. (together the "Group" or "AIB") announces that Mr Brendan McDonagh will not be putting himself forward for re-election as a Director at the forthcoming Annual General Meeting on 30 April 2026 and will step down as a Director at the conclusion of that meeting, having served just over nine years on the Board, including over six years as Board Risk Committee chair.

Mr Jan Sijbrand, who has served on the Board, and the Board Risk Committee, as a non-executive Director since September 2021, has been appointed as chair of the Board Risk Committee and will take over this responsibility from Mr McDonagh with effect from 25 March 2026. Mr McDonagh will remain as a member of the Board Risk Committee until his retirement and will work closely with Mr Sijbrand to ensure a smooth handover.

The Chair, Mr Jim Pettigrew, said:

"On behalf of the Board and the Group I want to record our sincere thanks to Brendan, who has made a remarkable contribution to the Board and to the Group since his initial appointment in October 2016. During the period since, and in addition to his excellent chairing of the Board Risk Committee, Brendan has served on the Nomination and Corporate Governance Committee, the Remuneration Committee and the Board Audit Committee. He served as interim chair between 2020 and 2021 at a time of enormous challenge presented by the COVID 19 pandemic and, since my appointment in late 2021, Brendan fulfilled the role of Deputy Chair. His support and advice in this role is something I have greatly appreciated. We wish Brendan continued success in the future.

I am very pleased that Jan will take over as chair of the Board Risk Committee. His leadership and credentials in this important area are well established in AIB and I expect the transition of responsibility from Brendan will be seamless."

This announcement is made in accordance with the Euronext Listing Rule 6.1.5 and UK Listing Rule 9.6.11.
