Sosei Heptares Announces Change of Market Listing Segment to the Tokyo Stock Exchange Prime Market

Tokyo, Japan and Cambridge, UK, 15 March 2023 – Sosei Group Corporation (“the Company”; TSE: 4565), the world leader in G protein-coupled receptor (GPCR) focused structure-based drug design (SBDD) and development, today announces it has changed the market on which the Company's shares are listed on the Tokyo Stock Exchange, Inc. (“TSE”) from the Growth Market segment to the Prime Market segment, effective today. 

Chris Cargill, President & CEO of Sosei Heptares, commented: “We believe that this move to TSE Prime is a key milestone in our vision to become one of Japan’s leading global biopharmaceutical champions. We are confident that a Prime Market listing will improve our ability to attract diverse institutional investors who are familiar with this industry, hold a long-term perspective and can support the acceleration of our growth driven by our core strategy.”


Rationale for the change

The Company’s vision is to become one of Japan’s global biopharmaceutical champions, discovering, developing and commercializing life-changing medicines for patients worldwide based on its world-leading science and expertise.

The Company expects the move to the Prime Market will help it to achieve its vision by providing enhanced support and access to the long-term capital through greater exposure to institutional investment funds, both domestic and international. This will result from a deepening and broadening of its shareholder base to reflect the global nature of the business.

(iii)    Advance at least two new in-house programs into first-in-human clinical trials; and
