IMUNON Successfully Regains Compliance with Nasdaq Minimum Bid Price Listing Requirement 

LAWRENCEVILLE, N.J., August 28, 2025 (GLOBE NEWSWIRE) — IMUNON, Inc. (Nasdaq: IMNN), a clinical-stage company in Phase 3 development of its DNA-mediated immunotherapy, today announced that the Company has regained compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market following confirmation from the Nasdaq Hearings Panel.

“Having regained compliance with Nasdaq’s minimum bid price listing requirement, investors in IMUNON’s stock are assured of efficient liquidity as provided by the exchange. Our ongoing confidence in our listing with the Nasdaq coincides with our recent 15% stock dividend to shareholders of record as of August 7, 2025, reflecting confidence in our clinical pipeline and commitment to rewarding investors,” said Stacy Lindborg, Ph.D., President and CEO of IMUNON. “It also builds on the positive momentum following our unprecedented Phase 2 OVATION 2 trial results for IMNN-001, our DNA-based immunotherapy for the localized treatment of advanced ovarian cancer, a disease that results in 20,000 women newly diagnosed annually in the U.S. alone. We have successfully initiated our Phase 3 OVATION 3 trial in North America, while continuing to advance milestones across our innovative TheraPlas® technology platform.”

About IMUNON

IMUNON is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. IMUNON is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the gene-based delivery of cytokines and other therapeutic proteins in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the gene delivery of viral antigens that can elicit a strong immunological response.

The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase 2 clinical trial (OVATION 2). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.
