## Geographic presence

AIB Group plc’s operations are concentrated in Ireland and the UK. Ireland is its principal market; its UK operations serve Great Britain and Northern Ireland. In the six months ended 30 June 2026, gross external revenue was €2,009 million in Ireland (approximately 88.0% of the €2,282 million total), €221 million in the UK (9.7%) and €52 million in the rest of the world (2.3%). Revenue is allocated mainly according to the location of the office recording the transaction. [1](https://app.finbar.com/go?id=P144488564)[5](https://app.finbar.com/go?id=P144488570)[22](https://app.finbar.com/go?id=P144489388)[23](https://app.finbar.com/go?id=T16534963)

For FY2025, country-by-country reporting showed turnover of €4,020 million in the Republic of Ireland, €446 million in the UK and €26 million in the rest of the world. Average full-time-equivalent employee numbers were 9,484 in the Republic of Ireland, 719 in the UK and 36 elsewhere. A separate year-end headcount disclosure reported 9,430 employees in the Republic of Ireland, 743 in the UK and 34 in the USA; these are distinct workforce measures. [24](https://app.finbar.com/go?id=T5977782)[25](https://app.finbar.com/go?id=T2371926)

The Group’s disclosed entities and operations include Allied Irish Banks plc, AIB Mortgage Bank and EBS in the Republic of Ireland, and AIB Group (UK) plc, trading as Allied Irish Bank (GB) and AIB (NI), in the UK. Its filings list registered offices in Dublin and Belfast. AIB’s official sources describe a 170-branch network in Ireland and list seven Northern Ireland branches. [26](https://app.finbar.com/go?id=P12313169)[27](https://app.finbar.com/go?id=T12291272)[28](https://aib.ie/content/dam/aib/group/Docs/Press%20Releases/2025/ccl-machines-pr.pdf)[29](https://www.aibni.co.uk/branchlocator)

Separately, AIB disclosed a borrower-country-of-risk exposure mix at June 2026 of 73% US, 19% Europe excluding the UK, 6% UK and 2% rest of world; this relates to that specific exposure measure, not the geographic distribution of revenue. [30](https://app.finbar.com/go?id=P144489269)

## Company history

AIB’s roots date to the founding of the Provincial Bank of Ireland in 1825, the Royal Bank of Ireland in 1836, and the Munster and Leinster Bank in 1885. The three banks amalgamated in 1966 to form Allied Irish Banks Limited. AIB expanded beyond the Republic of Ireland with its 1991 acquisition of TSB Bank Northern Ireland, and entered Poland in 1999 by acquiring an 80% stake in Bank Zachodni; Bank Zachodni later merged with Wielkopolski Bank Kredytowy in 2001 to form BZWBK. [38](https://aib.ie/content/dam/frontdoor/personal/sustainability/01%20Introducing.pdf) [39](https://aib.ie/content/dam/aib/investorrelations/docs/Annual%20General%20Meeting/2010/annual-financial-report-2009.pdf) [40](https://group.aib.ie/content/dam/aib/group/Docs/Press%20Releases/1999/1.%2824.06.1999%29%20AIB%20to%20buy%20Bank%20Zachodni.pdf) [41](https://aib.ie/content/dam/aib/group/Docs/Press%20Releases/2010/10-09-2010-aib-agrees-to-sell-its-polish-interests-for-eur3.1-billion.pdf)

In the United States, AIB acquired a stake in Dauphin Deposit Corporation in 1997 and later owned Allfirst Financial; Allfirst merged with M&T Bank in 2003. During the Irish banking crisis, the State recapitalised AIB and became its dominant shareholder. AIB acquired EBS in 2011, while deposits and related assets of Anglo Irish Bank were transferred to AIB that year. [42](https://www.federalreserve.gov/boarddocs/press/bhc/1997/19970519/) [43](https://group.aib.ie/content/dam/aib/group/Docs/Press%20Releases/2003/74.%20%2801.04.2003%29%20Merger%20of%20Allfirst%20Financial%20Inc.%20with%20M%26T%20Bank.pdf) [44](https://ec.europa.eu/competition/state_aid/cases/231023/231023_1153993_38_2.pdf) [45](https://aib.ie/content/dam/aib/group/Docs/Press%20Releases/2011/01-07-2011-aib-ebs-come-together-to-form-one-of-two-irish-pillar-banks.pdf) [46](https://aib.ie/content/dam/aib/group/Docs/Press%20Releases/2011/24-02-2011-aib-transfer-of-business-from-anglo-Irish-bank.pdf)

The State began selling shares through AIB’s 2017 initial public offering. That year, AIB Group plc became the listed holding company following a corporate reorganisation. The State’s shareholding declined over subsequent years, and its remaining shares were sold in June 2025, ending state ownership.
