SCYNEXIS Awarded BARDA Contract Providing Up to $214 Million in Non-Dilutive Funding for the Development of SCY-247

JERSEY CITY, N.J., September 28, 2026, SCYNEXIS, Inc. (NASDAQ: SCYX) ("SCYNEXIS" or "the Company"), a clinical-stage biotechnology company dedicated to advancing innovative solutions for severe rare diseases, today announced that it has been awarded a contract by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services, to advance the development of SCY-247, the Company's second-generation fungerp antifungal candidate.

"We are proud to partner with BARDA to advance the development of SCY-247, our antifungal designed to address the growing threat of antimicrobial resistance," said David Angulo, M.D., President and Chief Executive Officer of SCYNEXIS. "While we remain focused on SCY-770, our new product candidate for ADPKD, this partnership enables the development of a novel therapy for the treatment and prevention of serious invasive fungal infections while leveraging our existing infrastructure and capabilities. Importantly, it strengthens our pipeline by allowing us to advance two programs into Phase 2 and positions SCYNEXIS to create long-term value by addressing significant unmet needs in severe rare diseases."

Invasive fungal infections remain a significant public health threat, with limited treatment options and increasing resistance to existing therapies. SCYNEXIS is developing SCY-247 to address this unmet need, and BARDA's support reflects the strategic importance of strengthening U.S. preparedness against serious drug-resistant fungal infections through innovative antifungal therapies. If all options are exercised, the BARDA contract could fund the development of SCY-247 from its current stage through NDA submission for two indications: treatment of invasive candidiasis and prevention of invasive fungal infections in high-risk patients. The contract may be extended for up to 10 years and provides up to approximately $214 million in potential funding if all options are exercised. The initial base period of the BARDA contract provides approximately $18.5 million to support advancement of oral and intravenous SCY-247 into a Phase 2 trial in patients with invasive candidiasis.

The award is structured as a cost-share arrangement, with BARDA providing support for eligible SCY-247 costs, including both direct and general and administrative expenses. The Company expects to fund its share of near-term program costs for SCY-247 within its existing operating plan. The Company's previously communicated development plans for SCY-770 and the projected cash runway into 2029 remain unchanged.

This project has been funded in whole or in part with federal funds from the U.S. Department of Health and Human Services (HHS); Administration for Strategic Preparedness and Response (ASPR); Center for the Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50126C00007.

About SCY-247

SCY-247 is a second-generation triterpenoid (fungerp) antifungal candidate being developed for the treatment of invasive candidiasis and the prevention of invasive fungal diseases. As a member of a novel structural class, SCY-247 has a differentiated mechanism of action from existing antifungal classes and has demonstrated in vitro activity against a broad range of fungal pathogens, including strains resistant to currently available therapies. SCY-247 has been granted Orphan, Qualified Infectious Disease Product (QIDP) and Fast Track designations by the U.S. Food and Drug Administration. SCYNEXIS is developing both oral and intravenous (IV) formulations of SCY-247; positive Phase 1 single- and multiple-ascending-dose data for the oral formulation were reported in September 2025, and a Phase 1 study of the intravenous formulation has completed dosing with analysis ongoing.
