Further to the press release dated July 9, 2025, following the opinions issued by the employees representative bodies of the French entities concerned and the authorization granted by the LISI Board of Directors on October 23, 2025, LISI Group (Euronext Paris ISIN code FR0000050353 – FII) has entered into a binding agreement with the American company SK CAPITAL for the sale of the LISI MEDICAL division (meaning LISI MEDICAL - Head office in Neyron, LISI MEDICAL ORTHOPAEDICS - Caen, LISI MEDICAL FASTENERS - Neyron and LISI MEDICAL REMMELE - Minneapolis US).

LISI MEDICAL is specializing in medical device subcontracting, particularly orthopedic implants and minimally invasive surgery instruments. The division produces and packages machined products in titanium, chrome-cobalt and high-technology stainless steel for joint reconstruction (hip, knee, shoulder), traumatology, spine and minimally invasive surgery.

With €185.3M in sales revenue in 2024 and 857 employees distributed between France and the United States (with 2 production sites in each country), LISI MEDICAL positions itself as a global partner offering a complete "more than a part" solution, from raw materials to finished products that are sterilized and packaged, ready for the operating room.

The division actively supports major medical equipment manufacturers (OEMs) in their growth through its recognized industrial expertise, innovation capacity and certified quality standards.

This proposed transaction will enable LISI MEDICAL to benefit fully from SK CAPITAL's support in deploying its strategy, both in terms of organic growth and acquisitions.

Subject to obtaining the final approvals usually required, the transaction is expected to be finalized during the fourth quarter of 2025.
