Exhibit 99.1

HOPE Therapeutics, Inc. and NRx Pharmaceuticals (NASDAQ:NRXP) Announce Signing of Definitive Agreement to Purchase Kadima Neuropsychiatry Institute; Foundational Acquisition for the HOPE Network of Interventional Psychiatry Clinics

MIAMI, FL., May 13, 2025 – HOPE Therapeutics™, Inc. ("HOPE"), a medical and technology-driven company and wholly-owned subsidiary of NRx Pharmaceuticals, Inc. ("NRx" or the "Company") (NASDAQ: NRXP), a clinical-stage biopharmaceutical company, today announced signing of a definitive agreement to purchase the Kadima Neuropsychiatry Institute. Kadima is expected to serve as the clinical model for treatment offerings in HOPE-acquired clinics and is expected to continue its role as a leading investigative site for research into neuroplastic therapies including psychedelic medications, transcranial magnetic stimulation (TMS), and hyperbaric therapy.

Kadima is one of California’s flagship interventional psychiatry clinics and was among the first to bring ketamine treatment for central nervous system (CNS) disorders out of academic research settings and into clinical practice. The clinic offers a full range of treatments for suicidal depression, PTSD and other CNS disorders, including ketamine, Spravato, transcranial magnetic stimulation (“TMS”) as well as medication management. Further, Kadima and David Feifel, MD PhD, Founder and Medical Director of Kadima, have served as leaders in clinical trial work on emerging therapies in CNS for top companies in the industry. Importantly, the clinic is profitable and is forecast to continue growth going forward.

Dr. Feifel will join HOPE as its first Chief Medical Innovation Officer ("CMIO") upon closing of the acquisition. A nationally recognized expert in interventional psychiatry, Dr. Feifel’s distinctions include serving as an elected member of the American College of Neuropharmacology, peer-elected inclusion in “Best Doctors in America,” and citation in the Castle Connolly list of “Top Doctors” — a recognition given to only 10 psychiatrists in San Diego. Dr. Feifel sits on the Board of the Clinical TMS Society and has co-chaired its clinical standards committee. Dr. Feifel has served as lead investigator on numerous clinical trials of therapies for CNS disorders.

"The signing of a definitive agreement to acquire Kadima marks a pivotal moment in the execution of our strategy to redefine mental healthcare access and delivery of care through HOPE Therapeutics," said Dr. Jonathan Javitt and Matthew Duffy, Co-CEOs of HOPE . "Dr. David Feifel is a true pioneer in interventional psychiatry and we are honored to have him join our leadership team. With his guidance, we are accelerating the buildout of a world-class clinic network that integrates cutting-edge science with community-based care."

The planned acquisition of Kadima is subject to satisfaction of standard closing conditions and finalization of financing. Further details on the transaction will be disclosed at that time.
