BEDMINSTER, N.J., June 26, 2026 (GLOBE NEWSWIRE) -- Matinas BioPharma Holdings, Inc. (the “Company”) (NYSE American: MTNB) announced today that on June 24, 2026, it received a notice (the “Notice”) from the NYSE American LLC (the “NYSE American”) stating that the Company is not in compliance with the NYSE American continued listing standards set forth in Section 1003(a)(ii) of the NYSE American Company Guide (the “Company Guide”) requiring a company to have stockholders’ equity of at least $4.0 million if it has reported losses from continuing operations and/or net losses in three of its four most recent fiscal years. As of March 31, 2026, the Company had stockholders’ equity of $3.02 million and has had losses in the most recent five fiscal years ended December 31, 2025. As previously disclosed, the Company is also not in compliance with Section 1003(a)(iii) of the Company Guide requiring a company to have stockholders’ equity of at least $6.0 million if it has reported losses from continuing operations and/or net losses in its five most recent fiscal years. As of December 31, 2025, the Company had stockholders’ equity of $4.83 million and has had losses in the most recent five fiscal years ended December 31, 2025. Due to its non-compliance with Sections 1003(a)(ii) and 1003(a)(iii) of the Company Guide, the Company is subject to the procedures and requirements of Section 1009 of the Company Guide.

On May 4, 2026, the Company submitted a plan (the “Plan”) to the NYSE American advising of actions it has taken or will take to regain compliance with the continued listing standards. The Notice indicated that the NYSE American staff had determined to accept the Plan and grant the Company a plan period through October 2, 2027 (the “Plan Period,” and such date, the “Plan Period Deadline”). Accordingly, the Company is able to continue its listing during the Plan Period and will be subject to periodic reviews, including quarterly monitoring, for compliance with the Plan until it has regained compliance. However, there can be no assurance that the Company will be able to achieve compliance with such standards within the Plan Period. If the Company is not in compliance with the continued listing standards by the Plan Period Deadline, or if the Company does not make progress consistent with the Plan during the Plan Period, then NYSE American staff may initiate delisting proceedings as appropriate. The Company may appeal a staff delisting determination in accordance with Section 1010 and Part 12 of the Company Guide.

The Notice has no immediate impact on the listing of the Company’s shares of common stock, which will continue to be listed and traded on the NYSE American, subject to the Company’s compliance with the other listing requirements of the NYSE American. The Notice does not affect the Company’s ongoing business operations or its reporting requirements with the Securities and Exchange Commission.

About MAT2203

Matinas BioPharma’s MAT2203 is a potential oral broad-spectrum treatment for invasive deadly fungal infections. Although amphotericin B is a fungicidal agent, it is currently only available through an intravenous route of administration, which is known to be associated with several significant safety issues such as renal toxicity and anemia due to very high circulating levels of amphotericin B. MAT2203 has the potential to overcome the significant limitations of the currently available amphotericin B products due to its targeted oral delivery. Combining comparable fungicidal activity with targeted delivery results in a lower risk of toxicity and potentially creates the ideal antifungal agent for the treatment of invasive fungal infections. MAT2203 was successfully evaluated in the completed Phase 2 EnACT study in HIV patients suffering from cryptococcal meningitis, meeting its primary endpoint and achieving robust survival. MAT2203 was planned to be further evaluated in a single Phase 3 registration trial as an oral step-down monotherapy following treatment with AmBisome (liposomal amphotericin B) compared with the standard of care in patients with invasive aspergillosis who have limited treatment options.
