Results of Odd-lot Offer

AIB Group plc ("AIB" or the "Company") announces that following the closure of the Odd-lot Offer on Tuesday, 2 June 2026, the Company has purchased a total of 143,406 of its own ordinary shares ("Ordinary Shares") at €10.06 each.

Following approval of shareholders at the 2026 Annual General Meeting, the Odd-lot Offer was launched on 1 May 2026 to facilitate the disposal by Eligible Odd-lot Holders of their Ordinary Shares at a 5% premium, without the dealing costs that would typically render such a disposal uneconomic, whilst giving Eligible Odd-lot Holders the ability to opt-out of such a disposal. As set out in the announcement made on 1 May 2026, the purchase price of €10.06 per Ordinary Share represented a 5 per cent. premium to the volume weighted average price of AIB Ordinary Shares traded on Euronext Dublin over the five trading days up to and including 30 April 2026.

Following the implementation of the Odd-lot Offer, the number of individual on-register shareholder accounts has been reduced by 6,743.

Eligible Odd-lot Holders will receive their payment by cheque. Shareholders with a registered address in Ireland will be paid by cheque in euro and shareholders with a registered address in the United Kingdom will be paid by cheque in sterling (GBP).

It is expected that cheques will be despatched on 16 June 2026, at the risk of the relevant Odd-lot Holder.

As at close of business on 2 June 2026, the 143,406 Ordinary Shares purchased by the Company represented approximately 0.0068 per cent. of the existing issued share capital of the Company and will be cancelled.

Capitalised terms in this announcement, unless otherwise defined have the same meaning given to them in the circular sent to shareholders of the Company on 30 March 2026 (the "Circular").
