‍By bringing its teams closer to those of Atriom, a firm specializing in consolidation and valuation, Nexia S&A is sustainably strengthening its expertise in this strategic segment and affirming its ambition in the mid-market.

A demanding market, in tension, with high added value

Consolidation remains a narrow market — around 3,000 groups in France — but strategic in the mid-market segment.
