**GRI Bio Announces Closing of $8.0 Million Public Offering**

**LA JOLLA, CA**, December 12, 2025 (GLOBE NEWSWIRE) -- GRI Bio, Inc. (NASDAQ: GRI) ("GRI Bio" or the "Company"), a biotechnology company advancing an innovative pipeline of Natural Killer T ("NKT") cell modulators for the treatment of inflammatory, fibrotic and autoimmune diseases, today announced the closing of its previously announced public offering of an aggregate of 10,666,667 shares of its common stock (or common stock equivalents in lieu thereof), Series F warrants to purchase up to 10,666,667 shares of common stock (the "Series F Warrants"), at a combined public offering price of $0.75 per share (or per common stock equivalent in lieu thereof) and accompanying Series F Warrant. The Series F Warrants have an exercise price of $0.75 per share and are exercisable immediately upon issuance and will expire on the fifth anniversary of the initial issuance date.

H.C. Wainwright & Co. acted as the exclusive placement agent for the offering.

The aggregate gross proceeds to the Company from the offering were approximately $8.0 million before deducting the placement agent's fees and other offering expenses payable by the Company. The potential additional gross proceeds to the Company from the Series F Warrants, if fully exercised on a cash basis, will be approximately $8.0 million. No assurance can be given that any of the Series Warrants will be exercised. The Company intends to use the net proceeds from this offering for its product candidate development, working capital and general corporate purposes.

The securities described above were offered pursuant to a registration statement on Form S-1 (File No. 333-291999), as amended, which was declared effective by the Securities and Exchange Commission (the "SEC") on December 11, 2025.

Electronic copies of the final prospectus may be obtained on the SEC's website at http://www.sec.gov and may also be obtained by contacting H.C. Wainwright & Co., LLC at 430 Park Avenue, 3rd Floor, New York, NY 10022, by phone at (212) 856-5711 or e-mail at placements@hcwco.com.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy any of the securities described herein, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or other jurisdiction.

**About GRI Bio, Inc.**

GRI Bio is a clinical-stage biopharmaceutical company focused on fundamentally changing the way inflammatory, fibrotic and autoimmune diseases are treated. GRI Bio's therapies are designed to target the activity of NKT cells, which are key regulators earlier in the inflammatory cascade, to interrupt disease progression and restore the immune system to homeostasis. NKT cells are innate-like T cells that share properties of both NK and T cells and are a functional link between the innate and adaptive immune responses. Type I invariant NKT ("iNKT") cells play a critical role in propagating the injury, inflammatory response, and fibrosis observed in inflammatory and fibrotic indications. GRI Bio's lead program, GRI-0621, is an inhibitor of iNKT cell activity and is being developed as a novel oral therapeutic for the treatment of idiopathic pulmonary fibrosis, a serious disease with significant unmet need. The Company is also developing a pipeline of novel type 2 diverse NKT agonists for the treatment of systemic lupus

erythematosus. Additionally, with a library of over 500 proprietary compounds, GRI Bio has the ability to fuel a growing pipeline.
