NESS ZIONA, Israel, Nov. 14, 2025 (GLOBE NEWSWIRE) -- BiomX Inc. (NYSE American: PHGE) (“BiomX” or the “Company”), a clinical-stage company advancing novel natural and engineered phage therapies targeting specific pathogenic bacteria, today announced that it intends to effect a one-for-nineteen reverse split (the "Reverse Stock Split") of the Company’s common stock (the "Common Stock"). The Common Stock will continue to trade on the NYSE American under the existing symbol “PHGE” and will begin trading on a split-adjusted basis when the market opens on November 25, 2025. The new CUSIP number for the Common Stock following the Reverse Stock Split will be 09090D 509.

The Reverse Stock Split was previously approved by the Company’s stockholders at the 2025 Annual Meeting of Stockholders held on October 16, 2025, with the final ratio determined by the Company’s Board of Directors on November 13, 2025. The Company plans to file a Certificate of Amendment to the Company’s Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the Reverse Stock Split.

The 1-for-19 Reverse Stock Split will automatically combine and convert nineteen current shares of the Common Stock into one issued and outstanding new share of Common Stock. Proportional adjustments also will be made to shares underlying outstanding equity awards, warrants and convertible preferred stock, and to the number of shares issued and issuable under the Company’s stock incentive plans and certain existing agreements. The Reverse Stock Split will not change the par value of the Common Stock nor the authorized number of shares of Common Stock, preferred stock or any series of preferred stock.

The Reverse Stock Split will affect all stockholders uniformly and will not alter any stockholder’s percentage ownership interest in the Company’s equity, except for minor changes to the treatment of fractional shares as described below. After the effectiveness of the Reverse Stock Split, the number of outstanding shares of Common Stock will be reduced from approximately 29,006,165 to approximately 1,526,640 subject to adjustment to give effect to the treatment of any fractional shares that stockholders would have received in the Reverse Stock Split. No fractional shares of Common Stock will be issued in connection with the Reverse Stock Split. Stockholders of the Company who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will be automatically entitled to receive an additional fraction of a share of the Common Stock to round up to the next whole share. Continental Stock Transfer & Trust Company, the Company transfer agent, will send instructions to stockholders of record who hold stock certificates regarding the exchange of certificates for Common Stock. Stockholders who hold their shares of Common Stock in book-entry form or in brokerage accounts or “street name” are not required to take any action to effect the exchange of their shares of Common Stock following the Reverse Stock Split. Continental Stock Transfer & Trust Company may be reached for questions at (800) 509-5586.
