Why now? The move continues a run of acquisitions in recent years, notably in 2025, as Forvis Mazars builds out its multidisciplinary offer across all its markets in France.
"Through this operation, Forvis Mazars sends a very strong message to the French market," said Alain Chavance, partner and chief executive officer of Forvis Mazars in France (translated from French).
