Forvis and Mazars Combine Into a Global Network
A combination between Forvis and Mazars forms a global accounting network with meaningful scale:
- $5 billion in combined revenue
- 40,000 employees
- Nearly 1,800 partners
- Presence across 103 countries
Strategic Rationale
The merger brings together two established firms with complementary geographies and service capabilities. For clients operating across multiple jurisdictions, the new network offers a more unified service experience than either firm could deliver independently.
Expanded Geographic Reach
The combined footprint positions the network to serve multinational clients more effectively, with local capability across most major markets.
Broader Services and Solutions
The integration allows the network to deliver a fuller range of accounting, audit, tax, and advisory services — knitting together the specialist capabilities of both firms into a consistent global offering.
Unified Platform for Clients
Operating at scale across 103 countries positions the combined network to handle cross-border complexity — tax, regulatory, reporting, and advisory — under a single operating model rather than through a federation of loosely coordinated local firms.
Implications
For large multinational clients, the Forvis–Mazars combination expands credible choice beyond the Big Four for complex cross-border engagements. For the Big Four themselves, a new entrant at $5 billion in revenue with 103-country coverage is a meaningful competitive signal — particularly in mid-market advisory work where the Big Four have historically enjoyed scale advantages.
