Risks

• Forward-looking statements are subject to various factors, including the ability to satisfy conditions to the closing of offerings and other risks described in the company's SEC filings.
• TONMYA is contraindicated in patients with hypersensitivity to cyclobenzaprine, concomitant use of MAO inhibitors, during the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block, conduction disturbances, congestive heart failure, or hyperthyroidism.
• Potential for embryofetal toxicity with TONMYA, advising effective contraception for females of reproductive potential and a pregnancy test prior to initiation.
• Risk of serotonin syndrome with concomitant use of TONMYA and other serotonergic drugs (SSRIs, SNRIs, TCAs, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors).
• Tricyclic antidepressant-like adverse reactions, including arrhythmias, sinus tachycardia, prolongation of conduction time, myocardial infarction, and stroke, may occur with cyclobenzaprine.
• Caution is advised for TONMYA use in patients with a history of seizure disorder, as TCAs may lower the seizure threshold.
• Atropine-like effects of TONMYA require caution in patients with urinary retention, angle-closure glaucoma, increased intraocular pressure, and those taking anticholinergic drugs.
• TONMYA monotherapy may cause CNS depression, and concomitant use with alcohol, barbiturates, or other CNS depressants may increase this risk, advising against operating motor vehicles or hazardous machinery.
• Oral mucosal adverse reactions, such as oral hypoesthesia, oral discomfort, abnormal product taste, and aphthous ulcer, occurred more frequently with TONMYA.
• Drug interactions may occur with MAO inhibitors, other serotonergic drugs, CNS depressants, tramadol, guanethidine, or other similar acting drugs.
• Limited observational data on oral cyclobenzaprine use in pregnancy and lactation is insufficient to inform TONMYA-associated risks.
• The safety and effectiveness of TONMYA have not been established in pediatric or geriatric patients.
• The use of TONMYA is not recommended in patients with moderate or severe hepatic impairment, and a lower dosage is recommended for mild hepatic impairment due to increased cyclobenzaprine exposure.

Future Outlook

Priorities for 2026 include the successful commercialization of TONMYA, continued pipeline progress, and sustainable long-term value for patients and shareholders. The company expects to initiate a U.S. field study for TNX-4800 for Lyme disease prevention in 2027, pending FDA clearance, and plans to discuss Phase 2/3 development with the FDA in 2026. Enrollment for the TNX-102 SL (MDD) Phase 2 HORIZON study is expected to initiate in mid-2026, with topline data for the OASIS trial (TNX-102 SL for ASR/ASD) anticipated in the second half of 2026. A Phase 2 clinical trial for TNX-1500 (kidney transplant) is planned for initiation mid-year 2026, and a Phase 2 trial for TNX-2900 (Prader-Willi syndrome) is expected to initiate in the first quarter of 2027. Cash resources are projected to meet operating and capital expenditure requirements into the first quarter of 2027.

Management Comments

• "2025 was transformational for Tonix as we achieved FDA approval and began the U.S. commercial launch of TONMYA, our first fully in-house developed product and the first new medicine approved for fibromyalgia in more than 15 years." Seth Lederman, M.D., Chief Executive Officer.
• "We believe TONMYA now provides an alternative medicine for the approximately 10 million adults in the U.S. who suffer from fibromyalgia."
• "Early prescription trends reflect favorable prescriber uptake and repeat utilization consistent with our internal launch expectations."
• "We also meaningfully advanced our robust clinical pipeline in 2025."

Industry Context

StockSavvy.ai notes that the launch of TONMYA, the first new fibromyalgia treatment in over 15 years, positions Tonix as a significant player in a market with substantial unmet need, potentially disrupting existing therapies. The advancement of pipeline candidates for Lyme disease, MDD, and organ transplant rejection also aligns with broader industry trends focusing on high-impact, specialized treatments, indicating a diversified approach to addressing critical medical needs.

Comparison to Industry Standards

• The approval of TONMYA as the first new fibromyalgia medicine in over 15 years sets a new benchmark for innovation in this therapeutic area, where previous treatments like Lyrica (pregabalin), Cymbalta (duloxetine), and Savella (milnacipran) have been available for a long time.
• The early prescription uptake of TONMYA, with 1,500 prescribers and 2,500 patients initiating treatment within approximately two months, suggests a potentially strong initial market penetration compared to typical pharmaceutical launches, though specific comparable launch metrics for similar CNS drugs are not provided in the filing.
• The development of TNX-4800 for Lyme disease prevention addresses a critical public health need, as there are currently no FDA-approved vaccines or prophylactics, distinguishing Tonix from companies focused solely on treatment.

Stakeholder Impact

• Shareholders face potential for long-term value creation through TONMYA commercialization and pipeline advancements, but also dilution from recent capital raises and continued operating losses.
• Patients gain access to a new fibromyalgia treatment (TONMYA) and potentially future treatments for Lyme disease, MDD, Prader-Willi syndrome, and kidney transplant rejection.
• Healthcare providers have a new treatment option for fibromyalgia patients, supported by a salesforce and patient access programs.
• Employees are impacted by increased headcount mentioned in R&D and SG&A, indicating growth in staffing to support commercial and development activities.

Next Steps
