- Strong growth in the Audit & Assurance division (+14 %)
- Steady expansion of digital and AI literacy
- Pioneering decision for strategic partnership with PE investor Cinven
- Successful win of experts for key roles in the company
Düsseldorf, March 06th, 2026 – The audit and advisory firm Grant Thornton in Germany ended the 2024/25 financial year on September 30, 2025, with consolidated revenue of EUR 264 million (up 6 percent on the previous year). The Audit & Assurance division recorded particularly strong growth with an increase of 14 per cent compared to the previous year.
“Despite an adverse macroeconomic environment, we have continued to deliver robust growth with continued strong profitability in 2024/2025, which reflects the quality of our services and the trust from our clients”, says Prof. Dr. Heike Wieland-Blöse, CEO of Grant Thornton in Germany. "The economic crisis, geopolitical uncertainties, accelerated technological change, the competition for talent: We are facing these challenges with resilience and targeted strategic and personnel expansion of our services and our service portfolio. From this strong position, I am confident about the current financial year, which we have already got off to a good start. In line with our strategic growth plan, we already managed to win experts for key roles for future areas of our company.”
Development in the business divisions
The Audit & Assurance division has performed particularly well. This confirms that the right direction has been taken with the transformation process we have embarked on in the provision of services, which we will continue to pursue in the current financial year with the aim of ensuring the highest quality and professionalism at all times. Technologies such as generative AI, standardised and individual data analyses, process mining and innovative data transformation solutions are used specifically via secure use cases and support us and our clients. We see this as an effective stimulus for the consistently high quality and efficiency of our work as well as for a future-orientated client experience.
The Tax division pursued a targeted focus on special services with a broad industry spectrum, in particular tax managed services, M&A tax, as well as payroll. We are using this successful foundation for further capacity expansion in the current financial year. One example of the successful further development of the breadth of our specialization services is the expansion of our service offering in the areas of customs, energy tax and foreign trade law, with the customs law firm Peterka having moved to Grant Thornton in Germany in autumn 2025.
The Advisory division recorded particular growth in the Valuation & Economic and Dispute Advisory (VEDAS) service line, a service line for which Grant Thornton has been renowned in Germany for many years. The decline in M&A activity in the German economy was reflected in the areas focused on transaction support for clients. As part of a readjustment of the business division's focus, the new Resilience & Forensic service line was successfully established alongside the expansion of both the Public Sector Advisory service line as well as the expertise for the defense industry. The focus for the current financial year is on supporting clients in the transformation of business models, digitalization, innovation, risk management and long-term value creation.
The Legal division was able to win a cross-divisional team in the area of public law with regard to the energy industry, telecommunications and infrastructure, and further expanded its expertise in the area of liability (directors' and officers' liability in insolvency-related cases as well as liability cases in the financial services sector due to breaches of regulatory and contractual control requirements). In the past financial year, Legal won important restructuring mandates, in particular for the restructuring of companies in the real estate sector. The focus in the current financial year is on Financial Services, Real Estate and the public sector.
Focus on data, AI and digitalization
In the past financial year, Grant Thornton in Germany successfully established its AI governance – more extensively and earlier than required by the EU AI Regulation. In-house developments such as the intelligent chatbot "PurpleGPT" and the evaluation and rollout of further AI solutions such as Microsoft Copilot Chat and M365 Copilot, combined with comprehensive training and enablement of employees, have made a significant contribution to digital and AI literacy at Grant Thornton in Germany. The introduction of Microsoft Fabric laid the foundation for a single source of truth for structured data, which will serve as a company-wide data analytics platform in future and as a basis for the comprehensive use of the data processed in it by AI.
Strategic orientation for the future
In the 2024/2025 financial year Grant Thornton in Germany made the decision to enter into a strategic partnership with the international private equity investor Cinven. This strengthens our position as one of the leading quality providers and "trusted advisors" in the German audit and advisory market and puts us in the best possible position for the future to benefit of the opportunities associated with the transformation of the industry. The collaboration with Cinven gives Grant Thornton in Germany access to additional growth capital and industry-leading expertise, particularly in the areas of digitalization, artificial intelligence and process optimization.
"Last year, we specifically set the course for the future and opened a new chapter in our company's history in order to not only master the changes in our industry, but to actively shape them," says Wieland-Blöse. "We are consolidating our position as a quality service provider and trusted advisor for our customers. At the same time, we are establishing ourselves even more strongly as an attractive, future-oriented employer and offering our employees as well as new talents clear development prospects and the opportunity to make an impact within the company. Among the leading auditing and consulting firms in Germany, we are the first to offer participation in the company significantly earlier than at partner level."
Grant Thornton in Germany currently employs around 2,000 people (as at October 1, 2025). Numerous new hires at all career levels in the past financial year, including more than 20 external partner hires, have strengthened the firm's expertise, particularly in the service lines, as well as its industry expertise. At the same time, the internal training portfolio is being continuously expanded: Specialist training and further education and support systems for professional examinations and other certifications are just as much a focus as individual talent development at all career levels. Amongst others, female managers are supported by the established "go.ahead Female Talent Mentoring Program".
Part of a strong international network
Grant Thornton in Germany is the legally independent German member firm of the Grant Thornton International Ltd (GTIL) network. GTIL successfully closed the 2024/2025 financial year in December 2025 with a turnover of USD 8.5 billion (currency-adjusted growth of 6.1 percent). This marks the end of a five-year strategy cycle under former CEO Peter Bodin, during which the network grew from USD 6.6 billion in 2021 to USD 8.5 billion in 2025 (compound annual growth rate (CAGR) of 6.5 percent). The number of employees in the global Grant Thornton network rose to around 80,000.
