Basilea enters into agreement with BARDA to develop novel antifungals and antibacterials and receives initial funding

Initial funding of USD 29 million to support development of Basilea's clinical stage first-in-class antifungals, fosmanogepix and BAL2062 Multi-year Other Transaction Agreement (OTA) allows for potential funding of up to approximately USD 268 million to develop antifungal and antibacterial assets Increasing FY 2024 financial guidance on total revenue, operating result and net profit Ad hoc announcement pursuant to Art. 53 LR Allschwil, Switzerland, September 19, 2024 Basilea Pharmaceutica Ltd, Allschwil (SIX: BSLN), a commercial-stage biopharmaceutical company committed to meeting the needs of patients with severe bacterial and fungal infections, announced today that the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) within the US Department of Health and Human Services, has awarded Basilea an Other Transaction Agreement (OTA), under OTA number 75A50124C00033. As a result, Basilea increases its financial guidance for the full year 2024. David Veitch, Chief Executive Officer of Basilea, said: "Basilea has been working with BARDA since 2013. In continuing this partnership through an OTA, we will be leveraging our strong portfolio and the capabilities of our organization to develop urgently needed novel antifungals and antibacterials. We believe this long-term partnership will also lead to the successful implementation of our strategy to become a leading anti-infectives company." Under the terms of the OTA, BARDA will support the development of designated novel, first-in-class antifungals and antibacterials in Basilea's portfolio with a total potential non-dilutive funding of up to approximately USD 268 million over up to twelve years, if all additional options to extend the contract are exercised by BARDA upon successful completion of pre-defined milestones, including clinical and regulatory activities. With the signing of the OTA, initial BARDA funds of USD 29 million have been committed to support the development of the antifungals fosmanogepix and BAL2062. BARDA's financial contribution is assumed to be about 60% of the total costs over the term of the OTA. Under the OTA, BARDA and Basilea can jointly decide to move candidates into and out of the portfolio based on product performance, technical risk, and programmatic need. This flexibility results in significant time, effort, and cost savings to both partners. Increasing full-year (FY) 2024 financial guidance Reflecting the near-term impact of the OTA, Basilea updates its financial guidance for the full year 2024. Development costs under the OTA will continue to be reported under research and development expenses. The BARDA reimbursements will be reported under other revenue, resulting in increased total revenue and unchanged operating expenses. Also, additional deferred taxes are recognized due to the expected positive effect of the OTA on the company's medium-term financial outlook. This results in a higher operating result and net profit for FY 2024. (In CHF million) FY 2024e(new) FY 2024e(previous) FY 2023 Cresemba and Zevtera-related revenue ~190
