Second Quarter 2026 Financial Results Cash position: Tenax Therapeutics reported cash and cash equivalents of $118.0 million as of June 30, 2026. Proceeds of $13.4 million during the second quarter from exercises of previously issued warrants has enabled Tenax to extend its cash runway, and the Company now expects to fund its operations through the second quarter of 2028. Research and development (R&D): R&D expenses for the second quarter of 2026 were $12.9 million, compared to $6.1 million for the second quarter of 2025. The increase is primarily attributable to increased clinical and preclinical development costs associated with our ongoing Phase 3 LEVEL trial and our second global Phase 3 clinical trial, LEVEL-2, which began in December 2025. Selling, general and administrative (SG&A): SG&A expenses for the second quarter of 2026 were $5.9 million, compared to $5.7 million for the second quarter of 2025. The increase is primarily attributable to an increase in legal and professional fees as well as salary and benefit costs related to an increase in personnel, all partially offset by a decrease in stock-based compensation expense. Net loss: Tenax Therapeutics reported a net loss of $17.8 million for the second quarter of 2026, compared to a net loss of $10.9 million for the second quarter of 2025.
