June 22, 2026 – 8:45 a.m. – Diagnostic Medical Systems (Euronext Growth Paris: FR0012202497 – ALDMS), a specialist in high-performance medical imaging systems for digital radiology and bone densitometry, announces that at the Annual General Meeting held on June 15, 2026 at the company's headquarters, shareholders unanimously approved the appointment of Bpifrance Investissement as a director (5^th resolution) for a period of six years, i.e. until the end of the General Meeting to be held in 2032.

This appointment is in line with the commitments made during the capital increase carried out in August 2025, allowing Bpifrance Investissement to have representation on the Board of Directors. It aims to strengthen DMS Group's governance by involving a reference shareholder in strategic decision-making and providing complementary expertise in financing and development. As a reminder, following the capital increase in August 2025, entirely dedicated to the accelerated execution of the Imaging 2027 strategic plan and the implementation of a new Imaging 2030 strategic plan, Bpifrance Participations currently holds 6.3% of DMS Group's share capital.

The Board of Directors of DMS Group has therefore expanded from four to five directors, including three independent members, and two non-voting members:

• Samuel SANCERNI, Chairman of the Board of Directors,
• Bpifrance Investissement, Director, represented by Vladislav TCACI,
• Jean-François GENDRON, Independent Director,
• Marie-Laurence BORIE, Independent Director,
• Julien DELPECH, Independent Director,
• InnoLux Corp. and Innocare Optoelectronics Corp., board observer, represented by Tim YANG,
• Verso Capital, board observer, represented by Marko Järvinen.
