AIB has announced updates to its leadership team and is simplifying its management structure to further support the delivery of its Group strategy through our three main business lines: Retail Banking, Capital Markets and Climate Capital.
Graham Fagan, currently Chief Technology Officer (CTO), has been appointed Chief Operating Officer (COO). In this expanded role, Graham will lead the newly established Enterprise Delivery function, combining the Technology & Data and Operations & Business Services teams into a single, strategic delivery unit. This integration represents a key step in advancing a more cohesive, digitally-driven operating model—further enhancing the resilience, agility, and performance of services for customers and colleagues. A member of the Executive Leadership Team since 2023, Graham has led the transformation of the bank’s technology, data, and digital channels, and played a central role in the successful integration of AI across the organisation.
Miriam Nagle became Group General Counsel in January 2025 and is joining the Executive Leadership Team. She will continue to provide legal counsel to the Group and lead the legal function, as well as assuming additional accountability for third party management activity. Miriam began her legal career in private practice as a litigation specialist, advising on complex disputes across a range of sectors. She joined AIB in 2013 and has since held a variety of senior legal roles, contributing to strategic initiatives and governance across the organisation.
We are simplifying our management structure to focus on our three business lines, Retail Banking, Capital Markets, and Climate Capital. The UK business will now be part of Retail Banking. This integration will enhance our all-Ireland retail business offering across the island of Ireland and continue collaboration with Capital Markets and Climate Capital to align our wholesale business lines, improving operational efficiencies and customer experience.
AIB Group Chief Executive Colin Hunt said “I’m very pleased to announce Graham’s expanded role. He has shown innovation and an ability to deliver in his role as Chief Technology Officer and will continue to do so in Enterprise Delivery. Miriam’s appointment to our Executive Leadership Team recognises both her contribution and counsel since becoming Group General Counsel, and the broadening of her accountabilities announced today reflect her impact on the Group. Both of these appointments are evidence of the ability that has been fostered and developed within the Group. We look forward to their continued contributions.
Additionally, today’s updates to our management structure means AIB will focus on Retail Banking, Capital Markets and Climate Capital. This allows the bank to deliver on our strategic priorities of putting the Customer First, Greening our Business and focusing on Operational Efficiency and Resilience, meaning we can empower people to build a sustainable future.”
