Sosei Heptares Operational Highlights and Consolidated Results for the First Quarter 2023

Tokyo, Japan and Cambridge, UK, 12 May 2023 – Sosei Group Corporation (“the Company”; TSE: 4565) provides an update on operational activities and reports its consolidated results for the first quarter ended 31 March 2023. The full report can be found here.

Chris Cargill, President & CEO of Sosei Heptares, commented: “We are continuing to make good progress in building the foundation Sosei Heptares needs to become a leading international biopharmaceutical company headquartered in Japan by 2030.

“A key milestone in that journey was the elevation of our shares to the TSE Prime Market from the Growth Market and our inclusion in the TOPIX index. We are confident that this will improve our ability to attract an increasing number of institutional investors who are familiar with the biotech industry, hold a long-term perspective and can support the acceleration of our growth driven by the core strategy we unveiled and began executing last year. This strategy is focused on (1) enhancing our platform; (2) progressing our partnerships; (3) transforming our R&D; and (4) commercializing products in Japan.

“From a corporate perspective, we have also made great progress in establishing our ESG priorities and published these in our inaugural ESG report. We are working hard to embed these objectives into our business operations as well as our culture and values.

“I am very proud of what our team members in Japan and in the UK have accomplished so far in 2023 and look forward to the start of first-in-human trials for two of our inhouse programs and further progress across our extensive portfolio over the rest of the year.”

Financial Highlights for the Three-month Period ended 31 March 2023

• Revenue totalled JPY 943 million (US$7.1 million*), a decrease of JPY 176 million (US$2.5 million) vs. the prior corresponding period. The decrease is primarily due to the decrease in revenue related to royalties and other revenue, partially offset by the increase in revenue related to upfront fees and milestone income due to larger releases of deferred revenue.
• R&D expenses totalled JPY 1,957 million (US$14.8 million), an increase of JPY 153 million (a decrease of US$0.7 million) vs. the prior corresponding period. The increase is primarily due to increased investment in discovery activities, but also reflects the impact of the weaker Yen.
• G&A expenses totalled JPY 1,109 million (US$8.4 million), a decrease of JPY 245 million (US$3.3 million) vs. the prior corresponding period. This was primarily due to a decrease in restructuring costs.
• Operating loss totalled JPY 1,964 million (US$14.8 million) vs. operating loss of JPY 2,206 million (US$19.0 million) in the prior corresponding period. This decrease was primarily due to a reduction in G&A expenses and cost of sales, as well as an increase in net other income.
• Net loss before income tax totalled JPY 1,863 million (US$14.1 million) vs. a net loss before income tax of JPY 2,497 million (US$21.5 million) in the prior corresponding period. This decrease reflects the combined effect of all of the movements explained above.
• Net loss for the 3-month period ended 31 March 2023 totalled JPY 1,402 million (US$10.6 million) vs. net loss of JPY 2,070 million (US$17.8 million) in the prior corresponding period This decrease reflects the combined effect of all of the movements explained above.
