Mazars

What Mazars does

Forvis Mazars Group is an internationally integrated professional services network formed through the June 2024 merger of Paris-based Mazars (founded 1947) and U.S.-based Forvis. Headquartered in Paris, the firm operates across more than 100 countries and territories with approximately 40,000 professionals, serving organizations ranging from SMEs to the largest multinational corporations. The firm delivers a comprehensive portfolio organized around seven service lines: Audit & Assurance, Tax, Consulting (including management consulting, risk consulting, and technology and digital consulting), Financial Advisory, Legal Services, Outsourcing, and Sustainability Services. Audit & Assurance is the largest revenue contributor at 45% of total revenue with double-digit growth, and the firm organizes expertise through international sector communities spanning Financial Services, Consumer, Energy & Infrastructure, Life Sciences, Manufacturing, Private Equity, Public & Social Sector, Real Estate, and Technology/Media/Telecommunications. The combined entity ranks in the top 10 globally by revenue following the merger.

The firm operates as a private partnership, with ownership and control resting with its partners rather than public or institutional shareholders; no parent company, PE/VC ownership, or public listing is disclosed. Revenue is generated through quote-based B2B professional services engagements tailored to client scope and complexity, delivered via partner-led teams in directly operated country offices. Distribution is exclusively direct: the firm leverages its international office network and sector communities to coordinate cross-border service delivery for multinational clients, supplemented by lateral partner hiring from Big 4 competitors and strategic acquisitions to build capability in priority markets and verticals.

Growth is pursued through a combination of strategic acquisitions, lateral partner hiring, organic office openings, and capability-driven product launches. Notable transactions include the July 2023 acquisition of Advestis (an AI research firm) to build algorithmic and data science capabilities, the December 2022 acquisition of Samet & Company PC to deepen Boston financial services presence, and the January 2026 opening of a Birmingham, UK office. The combined entity reported $5.7 billion in global revenue for FY2024-2025, representing 11% year-over-year growth and marking the first full-year performance following the merger.
