Medincell’s ISS ESG Corporate Rating Upgraded

Medincell is ranked within the first decile of the Pharmaceuticals & Biotechnology sector, benefits from ISS ESG Prime Status, and achieves a very high level of ESG disclosure transparency.

This updated rating is based on ISS ESG’s independent assessment of multiple extra‑financial criteria, including:

• Social factors and product responsibility,
• Governance and business ethics requirements as defined within the ISS ESG methodology, and
• Selected environmental indicators monitored and reported by Medincell.

ISS ESG’s assessment is based on publicly available information and authorized exchanges with Medincell. ISS’ methodology and rating definitions remain proprietary. For further information:

Christophe Douat, CEO of Medincell, said: “We acknowledge this updated assessment and remain committed to advancing our ESG practices in line with our operational responsibilities and long‑term corporate strategy. ESG evaluations are increasingly integrated into the investment frameworks used by many institutional investors. The improvement of our ISS ESG corporate rating may enhance the clarity and comparability of our extra‑financial performance within these frameworks, helping stakeholders better assess how our practices align with their own risk‑management and sustainability criteria.”
