Daix (France), New York City (New York, United States), October 1, 2025 – Inventiva (Euronext Paris and Nasdaq: IVA) ("Inventiva" or the "Company"), a clinical-stage biopharmaceutical company focused on the development of oral therapies for the treatment of metabolic dysfunction-associated steatohepatitis ("MASH"), today announced the appointment of Andrew Obenshain as Chief Executive Officer ("CEO") of the Company. Mr. Obenshain will also join the Company's Board of Directors. He succeeds Frédéric Cren, the Company's co-founder, who has served as CEO since its inception in 2012. Mr. Cren is also stepping down from the Board of Directors and will work with Mr. Obenshain to ensure a smooth transition and continuity in the Company's strategic priorities.

This leadership transition reflects a strategic decision by the Board to support Inventiva's next stage of growth and development, with a particular focus on preparing for the potential commercialization in the United States, one of the leading markets for MASH, while continuing to build Inventiva's global footprint.

Mark Pruzanski, MD, Chairman of Inventiva's Board of Directors, stated: "With Phase 3 data on the horizon and and the preparation of potential marketing authorization applications underway, Inventiva is entering a defining moment. Andrew's global experience in drug approvals, launches, and organizational scaling, along with his patient-focused leadership, will enable Inventiva to strengthen its position as a leader in the MASH field and, potentially, bring lanifibranor to patients worldwide. On behalf of the Board, I want to thank Frédéric for his vision and leadership. Under his guidance, Inventiva has grown from a bold scientific idea into a late-stage biopharma advancing what we believe is one of the most promising oral therapies in development for MASH."

Frédéric Cren, co-founder of Inventiva, commented: "It has been the greatest achievement of my career to co-found Inventiva with Pierre Broqua and lead the Company for the past 13 years. Our extraordinary team has transformed a private biotech into a company listed on Euronext and NASDAQ that is recognized today as a leader in the MASH field. I am immensely proud of what we have accomplished and deeply grateful to all who have contributed to this journey. I am confident that Inventiva will continue to thrive and deliver on its mission to transform the MASH treatment landscape."

Andrew Obenshain, CEO of Inventiva, said: "Thanks to Frédéric's leadership, lanifibranor has emerged as one of the most advanced and differentiated therapeutic candidates in late-stage development for MASH. My focus will be on preparing the organization for potential global commercialization so that we are ready to serve patients worldwide. Inventiva combines scientific excellence and a genuine focus on patients, which are the essential ingredients to evolve the standard of care in MASH. I am looking forward to working with the team in the US and France to achieve this goal."

Mr. Obenshain was previously the CEO of bluebird bio, recently renamed Genetix Biotherapeutics, where he led the company's transformation into a global commercial-stage gene therapy enterprise, successfully securing multiple regulatory approvals across major geographies. He brings more than 20 years of global leadership in drug development, regulatory strategy, and commercialization across the United States, Europe, and international markets. Prior to bluebird, Mr. Obenshain held senior leadership roles at Shire and Genzyme/Sanofi in France, with a focus on rare diseases and specialty therapeutics. He holds a B.A. in Genetics, Cell & Developmental Biology from Dartmouth College and an M.B.A. from Northwestern University's Kellogg School of Management.
