Thomas Studhalter, CEO
Dear readers
The year 2025 demanded clear action. It was a year that called for decisiveness, responsibility and the ability to remain proactive even in the face of uncertainty.
This is precisely where we come in. Our role is to provide guidance when decision-making is complex and to support our clients so they can take timely action and set the right priorities.
BDO remains on a positive growth trajectory, generating revenue of CHF 293.6 million in 2025 – an increase of 4.2 percent on the prior year.

For the financial year 2025, BDO is reporting revenue performance for both member firms and alliance firms to provide a more comprehensive view of global revenue. All other figures reflect member firms of the global BDO network only.
Alliance firm: An alliance firm is not a member of the BDO network, but a legally and economically independent organisation that operates under its own brand and partners strategically with BDO on selected services.
Member firm: A member firm is an independent legal entity that is part of the global BDO network and operates under the BDO brand.
Our around 100 Partners hold an 80.5 percent stake in BDO, while our own pension fund holds the other 19.5 percent (as at 31.12.2025). Thomas Studhalter has been CEO of BDO since 1 January 2021. The Executive Committee also includes the five Heads of Regional Management and the Heads of Audit, Business Solutions and Tax & Legal, as well as the COO.
