About Tonix*

Tonix is a fully integrated biotechnology company, publicly traded on NASDAQ (ticker: TNXP), with marketed products and a pipeline of development candidates The Company is focused on commercializing, developing, discovering, and licensing therapeutics to treat and prevent human disease. In August 2025, Tonix received FDA approval for Tonmya™ (cyclobenzaprine HCl sublingual tablets), a first-in-class, once-daily, non-opioid treatment for fibromyalgia. Tonmya is the first new fibromyalgia therapy approved in over 15 years, following successful Phase 3 trials demonstrating significant symptom improvement. Commercial launch is expected in the fourth quarter of 2025. Tonix also markets Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg, both indicated for the treatment of acute migraine with or without aura in adults.

Tonix’s development portfolio includes product candidates in central nervous system (CNS), immunology, immuno-oncology infectious disease and rare disease. The CNS pipeline features both small molecules and biologics to treat pain, neurologic, psychiatric, and addiction conditions. The immunology portfolio includes biologics to address organ transplant rejection, autoimmunity, and cancer. The infectious disease pipeline includes a vaccine in development to prevent smallpox and monkeypox, which also serves as a live virus vaccine platform for other infectious diseases. Finally, the rare disease portfolio includes a product in development for Prader-Willi syndrome, which has both orphan drug designation and rare pediatric disease designation grants from the FDA.

Tonix owns and operates a state-of-the art infectious disease research facility in Frederick, Md.
