SELLS STAKE IN AIB/BNY SECURITIES SERVICES (IRELAND) LTD Allied Irish Banks, p.l.c. ("AIB") (NYSE: AIB) has today announced that it has entered into a definitive agreement with The Bank of New York Company, Inc (BNY) for the purchase by BNY of AIB's 50% stake in AIB/BNY Securities Services (Ireland) Ltd. (AIB/BNY). The transaction, which will require regulatory approval, is expected to be completed by the end of the third quarter of 2006. The profit and capital impacts will not be material for AIB. AIB/BNY Securities Services (Ireland) Ltd was established in 1995 as a joint venture between AIB and BNY to provide a range of services for a number of fund structures domiciled in Ireland. The JV, which currently has USD$210bn assets under administration, employs 600 staff between its Dublin and Cork offices. The net assets of the JV as at 31st October 2005 were USD$28.8m. Following the purchase of AIB's stake, all current AIB/BNY employees will join BNY and BNY will be the sole owner of the operation. Commenting on today's announcement Mon O'Driscoll, Head of Investment Banking, AIB Capital Markets said: "The agreement reached today is a natural and correct strategic decision for both AIB and BNY. Since its formation eleven years ago, AIB/BNY Securities Services (Ireland) Ltd. has grown to be one of Ireland's leading fund administration companies. AIB's knowledge and expertise of the local market was an excellent fit with BNY's global business model and the Joint Venture has enjoyed considerable success. Having reached significant scale it was natural for both parties to strategically review the partnership and decide how best to continue and develop the business. Continued success in the increasingly global custodial and funds administration business requires the focus and expertise of a company offering the scale and international presence of BNY. With its commitment to Ireland as a key part of its global funds administration platform and its long and impressive track record as a leading provider of securities service, BNY is ideally suited to take full control of the JV and ensure its further development and success". -ENDS- For further information please contact: Alan Kelly Catherine Burke General Manager, Group Finance Head of Corporate Relations AIB Group AIB Group Bankcentre Bankcentre Dublin 4 Dublin 4 Tel: +353-1-6600311 ext. 12162 Tel: +353-1-6600311 ext. 13894 Signatures Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorised.
