Cash Runway and Financing Strategy
To date, the Company does not have sufficient net working capital to meet its obligations over the next 12 months.
The Company's cash and cash equivalents totaled €17.0 million as of March 31, 2026.
After the completion of the IRIS Financing and assuming related gross proceeds of €19.3 million over a 24-month period, and based on its current plans, the Company estimates that its cash and cash equivalents will be sufficient to fund its operations until the end of December 2026. This cash runway does not include any potential future milestone payments from existing partnerships.
The IRIS Financing is the first step of a global financing strategy aiming at securing OSE's 3-year Strategic Plan and the Company is actively engaging with institutional investors in the United States and in Europe.
To further extend its runway beyond 2026, the Company continues to evaluate several complementary options, including a potential new strategic partnership involving one of its proprietary assets, equity offering to institutional investors, restructuring of its existing debt, and potential milestone payments from current partnerships.
Although the Company is confident in its ability to meet its short-term financing objectives, there is no guarantee that it will be able to obtain the necessary financing to meet its needs or to obtain funds at attractive terms and conditions to finance all of its activities on a 12-month horizon.
2025 Financial Statements have been approved on a going concern basis, although this situation constitutes a significant uncertainty that may cast significant doubt on the Company's ability to continue as a going concern beyond the currently estimated cash runway. Auditors' certification report will include a going concern qualification.
