AIB : Form of Proxy 2024 EGM

Explanatory Notes:

1. Pursuant to Section 1105 of the Companies Act, only those persons registered on the Company's register of members: (i) at 6.00 p.m. on Sunday 28 April 2024; or (ii) if the EGM is adjourned, at the close of business on the day before the date that falls 72 hours prior to the adjourned EGM (for the purposes of these Notes only, being a "Shareholder"), shall be entitled to attend and vote at the EGM or, if relevant, any adjournment thereof. Changes to entries on the Company's register of members after that time will be disregarded in determining the rights of any person to attend and vote at the EGM.
2. A Shareholder who is entitled to attend and vote at the EGM is entitled to appoint a proxy (or more than one proxy as alternates) to attend, speak and vote instead of the Shareholder. A proxy need not be a Shareholder. If you wish to appoint more than one proxy please contact the Company's Registrar, Computershare Investor Services (Ireland) Limited, on +353 1 247 5411. If you wish to appoint a proxy other than the Chair of the EGM, please insert the proxy's name and address and delete the words "the Chair of the EGM or".
3. To be valid, this Form of Proxy and any power or other authority under which it is executed (or a duly certified copy of any such power or authority) must be returned by post to Computershare Investor Services (Ireland) Limited, PO Box 13030, Dublin 24, Ireland or to Computershare Investor Services (Ireland) Limited, 3100 Lake Drive, Citywest Business Campus, Dublin 24, D24 AK82, Ireland, not later than 48 hours before the EGM or adjourned EGM or (in the case of a poll taken otherwise than at or on the same day as the meeting or adjourned meeting) at least 48 hours before the taking of the poll at which it is to be used.
4. This Form of Proxy must (i) in the case of an individual shareholder be signed or submitted electronically in accordance with Note (8) below by the shareholder or his/ her duly authorised attorney; or (ii) in the case of a corporate shareholder be given either under its common seal or be signed on its behalf by a duly authorised officer or

attorney of the corporate shareholder or submitted electronically in accordance with Note (8) below.

1. If this Form of Proxy is signed and returned without any indication as to how the person appointed is to vote, the proxy will exercise discretion as to how to vote or whether to abstain from voting.
2. Completion and return of this Form of Proxy (or submission of proxy instructions electronically) will not prevent a shareholder from attending and voting in person at the EGM.
3. In the case of joint holders, the vote of the senior holder who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the vote(s) of the other joint holder(s) and for this purpose seniority shall be determined by the order in which the names stand in the register of members in respect of the joint holding.
4. Internet Voting: If, as an alternative to submitting this Form of Proxy, you wish to appoint (or remove) a proxy electronically, you may do so by accessing the Registrar's website at www.eproxyappointment.com. You can access this site from any internet enabled computer. To log in you will require your unique PIN (which will expire at the end of the voting period), your Shareholder Reference Number (SRN) and your Control Number, all of which are shown at the top of the Form of Proxy. Electronic proxy voting may occur through the use of a secured mechanism to exchange electronic messages (as agreed with Euroclear Bank).
5. The "Withhold" option is provided to enable you to abstain from voting on the resolutions. However, it should be noted that a vote withheld is not a vote in law and will not be counted in the calculation of the proportion of votes for and against the resolutions.
