Forvis Mazars is an international audit, accounting and consulting business formed in June 2024 by an agreement between Mazars and Forvis.[3] Combined, the firms operate in the US and over 100[3] other countries, being among the top 10 global audit firms by revenue at the time of the agreement.[5][6]

History

The original Mazars firm was formed in Rouen, Normandy in France in 1945 by Robert Mazars.[7] He served as chief executive officer until 1983, when Patrick de Cambourg was appointed the position.[7] de Cambourg began internationalizing the firm, which counted 33 employees in 1977.[7][8] From 2011 to 2016, Philippe Castagnac served as chief executive officer.[8] He was succeeded by Hervé Hélias,[9] who currently holds the position.[9][10]

In 2023, the US-based Forvis acquired the US operations of Mazars, and an agreement was reached to operate internationally under the brand Forvis Mazars from June 2024.[5][3] Subsequently, the firms operate as a network, doing business as Forvis Mazars LLP in the United States and Forvis Mazars Group SC in other countries, with a combined global workforce of over 40,000.[4][11] The two firms are still owned by their respective partnerships, with separate profit pools, but are overseen by a global board.[3][1]

Since April 2019, US President Donald Trump's attorneys have been involved in a controversy regarding a House Oversight Committee request for financial records held by Mazars USA.[12][13] On 25 February 2021, the Committee reissued a subpoena for the documents previously sought.[13]

In 2022, following the collapse of FTX, Mazars was engaged by Binance to perform a "proof of reserves" audit.[14][15] This work was later halted, and Mazars decided to suspend all work with cryptocurrency-affiliated customers in December 2022.[15][16]
