Insights
UBS details 2026 leadership transitions and integration focus.
UBS outlines a planned Vice Chair succession, with Markus Ronner to be nominated at the AGM in April 2026, while Lukas G hwiler retires. The move concentrates regulatory, compliance, and governance expertise at the board level, aligning with UBS’s post-merger priorities.
Operationally, changes effective January 1, 2026 assign Michelle Bereaux to compliance and non-financial risk, expand Beatriz Martin to COO with responsibility for operational integration, and have Mike Dargan emphasize technology and innovation. Functions shift to CFO Todd Tuckner and HR head Stefan Seiler to streamline oversight.
The integration of Credit Suisse is described as on track to complete by the end of 2026, with client migrations largely advanced. Actual impact depends on execution of the new responsibilities and the AGM nomination outcome.

Changes to the UBS Board of Directors
●
Lukas Gähwiler decides to retire after 45-year career in financial services; will
not stand for re-election to UBS Group AG Board of Directors
●
Markus Ronner will be nominated as Vice Chairman of UBS Group AG Board of
Directors
Zurich, 24 October 2025 – Lukas Gähwiler will not stand for re-election to the UBS Group AG Board of
Directors at the Annual General Meeting (AGM) in April 2026. After an exceptionally successful career
spanning 45 years, he decided to retire from his role as Vice Chairman of the Board of Directors, concluding
his long career in banking.
Lukas Gähwiler has served UBS in several leadership roles: from 2010 to 2016 as member of the Group
Executive Board of UBS Group AG and President of UBS in Switzerland, followed by his tenure as Chairman of
UBS Switzerland AG. In 2022 he was appointed as Vice Chairman of the UBS Group AG Board of Directors. In
addition to his board responsibilities, he represented UBS in Switzerland’s most important trade associations
and financial industry organizations. As the final Chairman of Credit Suisse AG, he played a pivotal role in the
successful integration of Credit Suisse into UBS.
Colm Kelleher said: “It is with great appreciation and deep regret that I had to accept the resignation of
Lukas. On behalf of all of UBS, our clients and external partners, I want to thank him for his tremendous
contributions and unwavering commitment to UBS. Lukas is one of the most respected bankers in Switzerland
and has been a key driving force behind the success of UBS, particularly in Switzerland. He was instrumental
in preparing and executing the Credit Suisse transaction, and served as the final Chairman of Credit Suisse AG
during an exceptionally demanding transition. Personally, Lukas has been my closest partner since I joined
UBS. His expertise, social skills, integrity and work ethics set him apart. He will be greatly missed, and I wish
him only the very best for his new endeavors.”
Sergio P. Ermotti said: “Lukas has been a trusted partner throughout my entire career at UBS. As President
and later Chairman of UBS in Switzerland, he fundamentally repositioned and strengthened UBS in
Switzerland, significantly contributing to the Group’s success. Over the past nearly three years, it has been a
privilege to work closely with him on the successful integration of Credit Suisse. While I will miss him and his
invaluable contributions, I fully understand his decision to end his outstanding career in banking and embrace
new priorities.”
Markus Ronner is proposed to succeed Lukas Gähwiler and will be nominated as new member of the Board
of Directors and Vice Chairman at the AGM 2026. Markus Ronner is a Swiss citizen and has been with UBS
his entire professional career since 1981. Over the last 25 years, he has held several global leadership roles in
business, control and audit functions. Markus Ronner became a member of the Group Executive Board in

2018, when he took over his current role as the Group Chief Compliance and Governance Officer, overseeing
compliance, financial crime prevention and operational risk control as well as regulatory and governance
functions at the Group level. From 2022 to 2023 Markus Ronner also served as the chairman of UBS
Switzerland AG. He is a recognized expert in regulation, risk control and governance and well respected by
Swiss and international authorities.
Colm Kelleher said: “I congratulate Markus on his nomination. His extensive and unique experience in
financial services will provide the Board with valuable insights. In his role as Vice Chairman, he will represent
UBS across several key industry bodies. I am looking forward to working closely with him upon his election.”
Sergio P. Ermotti said: “Markus’s foundational work over the past 15 years helped shape the firm’s legal
structure and governance. Since joining the Group Executive Board in 2018 as Group Chief Compliance and
Governance Officer, Markus has navigated through a demanding non-financial risk environment, based on
industry-leading compliance, financial crime prevention and operational risk management standards and
established a robust resolvability framework for UBS. I thank Markus for his outstanding contributions and
look forward to continuing to work with him in his new role.”
The succession of Markus Ronner will be communicated separately.
