McDermott Will & Schulte advises Trèves family and Bpifrance on the sale of Trèves group to Autoneum

McDermott Will & Schulte advised the Trèves family and Bpifrance on the sale of Trèves Group, a leading provider of soundproofing, thermal insulation, interior trim, and trunk solutions for the automotive industry, to Autoneum, a Swiss-based group and global leader in acoustic and thermal management solutions and high-performance protection systems for vehicle underbodies and batteries.

With approximately 4,600 employees and annual revenue of approximately EUR 720 million in FY2025, Trèves Group operates 26 production sites in 15 countries across Europe, North America, South America, Asia and Africa and serves a broad range of global automotive manufacturers.

This acquisition will enable Autoneum to strengthen its technology portfolio and expand its industrial and geographic footprint. The combined entity is expected to generate pro forma revenue of more than 2.9 billion Swiss francs in 2026.

The upfront consideration payable at closing will consist of newly issued Autoneum shares in addition to a cash payment. The shares will be subject to a three-year lock-up period. A new underwritten credit facility (senior unsecured term loan) of CHF 200 million, maturing in December 2029, will finance Trèves’ ongoing business operations, including the refinancing of existing bank financing and working capital requirements.

The transaction remains subjected to obtaining the necessary regulatory approvals expected to close in early Q1 2027.
