Boulogne-Billancourt, September 2, 2025 – Cegedim, an innovative technology and services company, announces that trading in its shares is being transferred from the regulated market of Euronext Paris (compartment B) to Euronext Growth Paris, effective September 4, 2025.

The Euronext admission committee approved the application to admit CEGEDIM S.A. shares to Euronext Growth Paris on August 29, 2025.

The transfer was authorized by the General Shareholders' Meeting of June 13, 2025, and initiated by the Group's Board of Directors. It will raise the profile and enhance the appeal of the share and will also entail some regulatory relief.

Even so, the Group will maintain its current level of financial communication.
