BDO posted revenue of CHF 293.6 million for the 2025 financial year, up 4.2% from the previous year. The Tax & Legal division delivered a particularly strong performance. At the same time, cross-functional advisory services gained in importance, especially in connection with company sales and digital solutions for businesses.

Supporting clients in an increasingly complex environment
In 2025, determination and resilience were essential. Economic and regulatory frameworks have profoundly reshaped the way companies make decisions.

Thomas Studhalter, CEO, explains: « Markets, regulation and technology can no longer be considered 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 them with guidance so they can make informed decisions. »

For many companies, a central question therefore emerged: how can they integrate these new requirements, seize technological opportunities and meet operational imperatives? This trend translated into higher demand for services through which BDO supports its clients in a cross-functional way, drawing on the full breadth of its expertise.

Digitalisation as the engine of our growth
In 2025, BDO decisively accelerated the development of its services, with digitalisation as the main lever. The focus was placed 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 continues to invest consistently in the professional development of its employees. Around five percent of the total budget is allocated to training and continuing 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 banner. As of 1 January 2026, that 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 seen in recent years, reaching revenue of CHF 98.0 million, up 2.2%.

Stricter requirements in terms of documentation, risk-based approaches and transparency remain at the top of the sector’s agenda. To meet these demands, 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 of 1 January 2025, certain services previously classified under Risk and Performance Advisory Services no longer fall under audit but under advisory. On a like-for-like basis, core audit activities therefore grew by around 6%.

The Fiduciary business also posted a positive performance (CHF 90.6 million, +1.1%). More and more companies are opting for 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 launched a coherent transformation in 2025, evolving its positioning from a traditional fiduciary provider to a supplier of advanced technology-based solutions.
Tax & Legal also delivered a strong year (CHF 37.8 million, +7.9%). It was shaped by a complex geopolitical, regulatory and economic environment, with direct implications for tax matters. As a result, demand for specialist tax and legal advice continued to rise.

Within Financial Services, the emphasis was placed on strategic direction, greater efficiency and the development of specialised audit and advisory capabilities. Despite a rationalisation of the service offering, revenue remained stable (CHF 19.4 million) and provides 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. After a period of caution, the mergers and acquisitions (M&A) market showed signs of recovery. In addition, many companies stepped up investment in order to evolve 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 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 decline 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.

Further information on the development of activities in 2025 and on the sustainability report is available at www.bdo.ch/ra2025 and www.bdo.ch/rapportdurabilite2025.
