BDO posted revenue of CHF 293.6 million for the 2025 financial year, up 4.2% year on year. The Tax & Law division recorded particularly strong growth. At the same time, cross-functional advisory services gained in importance, especially in connection with corporate sales and digital solutions for businesses.

Support in an increasingly complex environment
In 2025, determination and resilience were required. Economic and regulatory frameworks fundamentally reshaped how companies make decisions.

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

For many companies, one central question therefore came to the fore: how can these new requirements be integrated, how can technological opportunities be harnessed and how can operational imperatives be met? This trend translated into stronger demand for services through which BDO supports its clients in a cross-functional manner, drawing on the full range of its areas of expertise.

Digitalisation as the engine of our growth
In 2025, BDO decisively accelerated the development of its services, using digitalisation as 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 most of the skills and experience of our employees.
At the same time, BDO continues to invest consistently 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 effort.

In 2025, BDO prepared the consolidation of all its digital entities under the BDO Digital umbrella. Since 1 January 2026, this step has been completed and the “BDO Digital” brand is now being used in the market.

Diversification of activities
The Audit business continued the positive trend seen in 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 meet them, BDO made targeted investments in quality management and in the technologies supporting the audit process, thereby consolidating its high quality standards. It should also be noted that, as of 1 January 2025, certain services previously classified under Risk and Performance Advisory Services are no longer part of audit, but of advisory. On a like-for-like basis, core audit activities therefore grew by around 6%.

Fiduciary also recorded a positive development (CHF 90.6 million, +1.1%). An increasing number of companies are opting for integrated solutions combining fiduciary services, digital processes and management consulting. At the same time, automation and standardisation are profoundly changing 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 & Law also delivered a successful year (CHF 37.8 million, +7.9%). It was shaped by a complex geopolitical, regulatory and economic environment, with direct implications for tax issues. As a result, demand for specialised tax and legal advice continued to rise.

Within Financial Services, the emphasis was placed on strategic direction, greater efficiency and the development of specialist audit and advisory capabilities. Despite a streamlining of the service offering, revenue remained stable (CHF 19.4 million), providing a solid basis 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. After a period marked by caution, the mergers and acquisitions (M&A) market showed signs of recovery. In addition, many companies stepped up their investments to evolve their business models and optimise their processes.

BDO Sustainability Report 2025
Alongside the publication of its annual report, BDO is also issuing its 2025 Sustainability Report, which highlights progress achieved in key areas of corporate responsibility. During the year under review, BDO was able to reduce its overall emissions by 10.9% compared with the previous year. This decrease is 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 the EcoVadis silver medal for the first time, placing it among the top 15% of companies worldwide.
