Appointment of CEO

OSB GROUP PLC (“OSBG” or the “Group”) is very pleased to announce the appointment of Enrique Alvarez Labiano as Chief Executive Officer (CEO), subject to regulatory approval, with effect from a date to be agreed. This appointment follows a comprehensive search process conducted by the Board, facilitated by a global executive search firm and managed by David Weymouth, Chair, which considered both internal and external candidates.

Enrique is CEO of Retail and Business Banking and an Executive Director of Santander UK plc and Santander UK Group Holdings plc. He joined Santander Group in 2015, progressing through senior strategy roles, including Group Head of Strategy and Chief of Staff to the Executive Chair, during which he also led the Group’s Insurance Business and Responsible Banking. Moving to the UK in 2019, he became Head of Strategy and Corporate Development before serving as Chief People Officer (2020) and Head of Everyday Banking (2021). He has been CEO of Retail and Business Banking since 2023 and joined the Santander UK Board in February 2025. Earlier in his career, he worked as Partner at McKinsey & Company (2007–2015). He holds an MEng from ICAI, Pontificia Comillas University, and an MBA from INSEAD.

Enrique will succeed Andy Golding, whose intention to retire was announced on 13 November 2025.

A further announcement will be made in due course regarding the date on which Enrique will join OSBG.

David Weymouth, Chairman of OSBG, said: “Enrique brings compelling strategic vision having extensive experience leading group-level strategy at Santander. His strong track record in retail and business banking, together with his excellent leadership experience will be instrumental in building on the strengths of the existing management team, and I look forward to welcoming him to OSBG”.

Enrique Alvarez Labiano said: “I am honoured to have been chosen to lead OSBG, a Company with a clear commitment to its customers. I look forward to working with colleagues across the organisation to build on the strong foundations and strategy already in place and to continue supporting customers, communities and shareholders.”

Andy will continue as a Board director and Group CEO until Enrique joins OSBG and, alongside the Board and the experienced executive team, will continue to focus on delivering the Group’s strategy, including the 2026 financial guidance and medium-term aspirations, set out at the Investor Update in March 2025.

Andy Golding, CEO of OSBG, said: “Enrique will be warmly welcomed at OSBG and will be supported by a highly committed and experienced team across the Group as it continues to deliver on its purpose. I wish him every success as he takes the business forward.”
