BDO posted revenue of CHF 293.6 million for the 2025 financial year, up 4.2% year on year. The Tax & Legal division delivered a particularly strong performance. At the same time, cross-functional advisory services became more important, notably in company sales and digital solutions for businesses.

Support in an increasingly complex environment
2025 called for determination and resilience. Economic and regulatory frameworks profoundly altered how companies make decisions.  

Thomas Studhalter, CEO, explains: « Markets, regulation and technology can no longer be viewed separately. Our clients must make decisions in which economic, regulatory and technological developments intersect. Our role is to put these links into perspective and provide guidance, so that they can make informed decisions. » 

For many companies, one key question therefore emerged: how can they integrate these new requirements, harness technological opportunities and meet operational imperatives? This trend translated into stronger demand for services in which BDO supports its clients in an integrated way, drawing on the full breadth of its expertise.  

Digitalisation, the engine of our growth
In 2025, BDO decisively accelerated the development of its services, making digitalisation its main lever. The focus was on the targeted use of digital solutions and the systematic optimisation of internal processes. 

Digital tools and automated processes enabled us to significantly reduce administrative tasks and devote more time to high-value audit and advisory mandates. This made it possible to make the best use of the skills and experience of our employees.  
At the same time, BDO consistently invests in the professional development of its employees. Around five per cent of the total budget is allocated to training and further education. Skills development in technology is also part of an ongoing approach.  

In 2025, BDO prepared the consolidation of all its digital entities under the BDO Digital banner. As of 1 January 2026, this step has been completed and the « BDO Digital » brand is now used in the market. 

Diversification of activities
The Audit business continued the positive trend of recent years, reaching revenue of CHF 98.0 million, up 2.2%. 

Stricter requirements in terms of documentation, risk-based approach and transparency remain at the heart of the sector’s priorities. To address them, BDO made targeted investments in quality management and in technologies supporting the audit process, thereby reinforcing its high quality standards. It should also be noted that, as from 1 January 2025, certain services previously classified under Risk and Performance Advisory Services are no longer part of audit, but of advisory. On a comparable basis, core audit activities therefore grew by around 6%. 

The Fiduciary business also posted positive growth (CHF 90.6 million, +1.1%). More and more companies are favouring integrated solutions combining fiduciary services, digital processes and management consulting. At the same time, automation and standardisation are fundamentally reshaping traditional fiduciary processes. Against this backdrop, BDO undertook a consistent transformation in 2025, evolving its positioning from a traditional fiduciary provider to a supplier of advanced technology-based solutions.  
Tax & Legal also delivered a successful year (CHF 37.8 million, +7.9%). The year was marked by a complex geopolitical, regulatory and economic environment, with direct implications for tax matters. As a result, demand for specialised tax and legal advice continued to grow.  

Within Financial Services, the focus was on strategic direction, greater efficiency and the development of specialised audit and advisory skills. Despite streamlining the service offering, revenue remained stable (CHF 19.4 million), providing a solid foundation for the future development of our client-focused services. 

Other services generated revenue of CHF 47.8 million, up 14.1%, with particularly strong performances in Deal Advisory and Abacus activities. After a period marked by caution, the mergers and acquisitions (M&A) market showed signs of recovery. In addition, many companies stepped up investments to adapt their business models and optimise their processes. 

BDO Sustainability Report 2025
Alongside the publication of its annual report, BDO is also releasing its 2025 sustainability report, which highlights progress made in key areas of corporate responsibility. During the year under review, BDO reduced its overall emissions by 10.9% compared with the previous year. This decline was due, among other things, to a further reduction in emissions linked to business travel and employee mobility. For its sustainability performance, BDO Switzerland was awarded an EcoVadis silver medal for the first time, placing it among the top 15% of companies worldwide. 

Further information on business developments in 2025 and on the sustainability report is available at www.bdo.ch/ra2025 and www.bdo.ch/rapportdurabilite2025.
