MANAGEMENT & PRIVATE INVESTORS

FRANCE Software / Industry-Specific Software / Defense & Aerospace EV 50M - 150M EUR

Context

This transaction marks the acquisition of a majority stake in MASA Group by Nicolas Walewski, facilitating the exit of the previous financial sponsors.

Due to the strategic nature of the target's simulation technology for national defense, the deal required formal government clearance before completion.
