Summary
Ardian, the Paris-based alternative investment manager, has completed the sale of its stake in TRIGO to Montyon Capital, a French investment fund. TRIGO operates as a specialist provider of inspection, quality engineering, and industrial performance management services focused on the transportation sector. The transaction marks Ardian's exit from the asset, though specific deal valuation and timing details were not disclosed in available sources.

The involvement of Montyon Capital and Redbird in acquiring these assets indicates sustained demand from acquisition-focused investment vehicles for established industrial and specialized service providers.
