Key highlights for the first full year of operation under the new management team include:

A year-over-year reduction in operating expenses with $7.8 Million cash on hand at year end. With ongoing revenue from operations and current ATM trends, the Company anticipates adequate resources to support operations through 2026, with anticipation of continued revenue growth. As of December 31, 2025, all previously issued convertible debt had been converted into common stock.
Anticipated FDA approval of at least one new drug – Preservative Free Ketamine under an ANDA—during Q3 2026. A favorable preliminary bioequivalence determination was received from the FDA last week.
A Type C in-person meeting with the FDA Division of Psychiatry Products together with leadership of the FDA Center for Drug Evaluation and Research (CDER) to identify a path to approval of NRX-100 (preservative-free ketamine) under a New Drug Application with an indication for treatment of Severe Depression in Patients who may have suicidality. In meeting minutes, FDA expressed willingness to review existing randomized clinical trial data and Real World Evidence as a potential basis for approval without a requirement for conduct of additional clinical trials.
Appointment of Prof. Joshua Brown, MD, PhD, of Harvard/Mclean as Chief Medical Innovation Officer. Dr. Brown is Principal Investigator on NIH- and DARPA-funded projects that highlight the future of neuroplastic care, including use of D-cycloserine and TMS for treating depression, PTSD, and suicidality.

Development of a patentable, sustained-release presentation of D-cycloserine to provide an extended release profile suitable for enhancement of TMS efficacy. Prior clinical trials have shown a doubling of clinical response in patients with depression and an 8-fold increase in remission from depression versus standard TMS therapy.
Implementation of a business plan for HOPE Therapeutics, Inc. with the aim of developing interventional psychiatry centers focused on neuroplastic therapy – including ketamine, D-cycloserine, Transcranial Magnetic Stimulation, and Hyperbaric Oxygen Therapy – for patients with severe and suicidal depression and PTSD, with future applications for Traumatic Brain Injury, Autism, and Alzheimer's.
First revenue from acquired and partnered interventional psychiatry clinics at five sites of care that provide neuroplastic therapy to treat severe and suicidal depression and PTSD, with funding from the Department of Veterans Affairs, the Department of War, private insurers, and self-pay. Company expects to substantially increase this revenue-generating footprint in 2026.

"2025 was a pivotal year for NRx and HOPE Therapeutics as we have advanced two lifesaving drugs towards FDA approval with the aim of initiating commercial pharmaceutical operations by the end of this year. We ended the year debt-free and attracted fundamental long-term investors who believe in our mission," said Dr. Jonathan Javitt, the Company's CEO and Chairman. We have opened our first HOPE Therapeutics Clinics and are witnessing firsthand the impact that properly coordinated neuroplastic care can have on patients and their families who suffer from depression, PTSD, and suicidality. Clinical response rates approaching 90% have been reported in the medical literature for the combination of neuroplastic drugs, Transcranial Magnetic Stimulation, and Hyperbaric Oxygen Therapy. We look forward to a world in which physician-led neuroplastic care replaces a world of older antidepressants and electroshock therapy. We are deeply grateful to the trust that has been afforded us by our patients, their families, and our shareholders."

For the year ended December 31, 2025, NRx Pharmaceuticals reduced its loss from operations by approximately $2.3 million to $16.2 million from $18.5 million for the year ended December 31, 2024, which was primarily driven by a decrease in research and development expense. For the year ended December 31, 2025, research and development expense decreased by approximately $2.4 million to $3.8 million as compared to $6.2 million for the year ended December 31, 2024 primarily driven by a decrease in clinical trial and development expense. Finally, general and administrative expense for the year ended December 31, 2025 decreased by approximately $0.4 million to $13.1 million as compared to $13.5 million for the year ended December 31, 2024 primarily driven by certain ongoing cost reduction initiatives.
