Insights

Equity structure and corporate actions analyst

BiomX is consolidating its equity with a 1:19 reverse stock split effective November 25, 2025.

BiomX Inc. has approved a one-for-nineteen (1:19) reverse stock split of its common stock, effective at 12:01 a.m. Eastern Time on November 25, 2025. After this action, each block of nineteen existing shares will represent one new share, while the company’s overall authorized share count and the par value of the common stock remain unchanged.

This type of transaction reduces the number of shares outstanding and typically increases the trading price per share mechanically, although the total economic interest per holder is intended to stay the same. The company states that rights and preferences of the common stock are not affected, and no cash is paid for fractional shares; instead, fractional positions will be rounded up to the next whole share, slightly increasing some holders’ share counts.

The company will also make proportional adjustments to equity awards, warrants, convertible preferred stock, and the number of shares available under stock incentive plans, preserving the economic terms of those instruments on a per-holder basis. The shares are expected to begin trading on a split-adjusted basis on November 25, 2025, once the certificate of amendment becomes effective.

Item 3.03 Material Modification to Rights of Security Holders.

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 of this Current Report on Form 8-K (this “Form 8-K”) is incorporated herein by reference.

Item 5.03 Amendments to Articles of Incorporation or Bylaws.

As previously reported in a Current Report on Form 8-K filed by BiomX Inc. (the “Company”) on October 17, 2025, at the annual meeting of the Company’s stockholders held on October 16, 2025, the holders of a majority of the Company’s outstanding shares of common stock, par value $0.0001 per share (the “Common Stock”), voted to approve the authorization of the Company’s Board of Directors (the “Board”) to amend the Company’s certificate of incorporation, as amended (“Certificate of Incorporation”), to effect a reverse stock split of the Common Stock at a ratio between at least one-for-five (1:5) and less than one-for-twenty (1:20), to be determined in the sole discretion of the Board. On November 13, 2025, the Board approved a one-for-nineteen (1:19) reverse stock split (the “Reverse Stock Split”) of the outstanding shares of Common Stock, and authorized the filing of a certificate of amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Certificate of Amendment”) to effect the Reverse Stock Split. The Company plans to file the Certificate of Amendment to effect the Reverse Stock Split as of 12:01 a.m. Eastern Time on November 25, 2025 (the “Effective Time”). The outstanding shares of Common Stock are expected to begin trading on the NYSE American on a split-adjusted basis at the start of trading on November 25, 2025.

As a result of the Reverse Stock Split, every nineteen (19) shares of Common Stock issued and outstanding as of the Effective Time will be converted into one (1) share of Common Stock (the “New Common Stock”). The New Common Stock will have a new CUSIP number of 09090D 509. The Reverse Stock Split does not affect the total number of shares of capital stock, including the Common Stock, that the Company is authorized to issue, which shall remain as set forth pursuant to the Certificate of Incorporation. The Reverse Stock Split will not affect the rights, preferences or par value of the Common Stock. No fractional shares of New 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.

Proportional adjustments also will be made to shares of Common Stock 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. If no provisions exist in such instruments, the exercise or conversion price of such instruments with respect to each pre-Reverse Split share of Common Stock shall be multiplied by the ratio of the Reverse Split and the number of shares of Common Stock underlying such instrument shall be divided by the ratio of the Reverse Split.

Continental Stock Transfer & Trust Company, the Company’s transfer agent, will send instructions to stockholders of record who hold stock certificates regarding the exchange of certificates for New 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, and their accounts will be automatically adjusted to reflect the Reverse Stock Split.

The foregoing summary of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

Safe Harbor

This Form 8-K contains express or implied “forward-looking statements” within the meaning of the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: “target,” “believe,” “expect,” “will,” “may,” “anticipate,” “estimate,” “would,” “positioned,” “future,” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. For example, when BiomX discusses the effective date for the Reverse Stock Split and the date that trading of the New Common Stock will begin on a split-adjusted basis, it is using forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on BiomX management’s current beliefs, expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of BiomX’s control. Therefore, investors should not rely on any of these forward-looking statements and should review the risks and uncertainties described under the caption “Risk Factors” in BiomX’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2025, and additional disclosures BiomX makes in its other filings with the SEC, which are available on the SEC’s website at www.sec.gov. Forward-looking statements are made as of the date of this Current Report on Form 8-K, and except as provided by law, BiomX expressly disclaims any obligation or undertaking to update forward-looking statements.
