Amendment to Warrant

As previously reported in a Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on December 29, 2025 (the “Prior 8-K”), on December 26, 2025, BiomX Inc. (the “Company”) entered into a Securities Purchase Agreement, with an investor (the “Investor”), pursuant to which the Company agreed to issue and sell in a private placement, up to 3,300 shares of the Company’s Series Y Convertible Preferred Stock, par value $0.0001 per share, and a warrant (the “Warrant”) to purchase up to 3,300,000 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), at an initial exercise price of $2.00 per share, which expires five years from the date of issuance.

On March 13, 2026, the Company and the Investor entered into an amendment to the Warrant (the “Warrant Amendment”), pursuant to which, the Investor and the Company agreed to (i) amend the term of the Warrant, such that the Warrant will expire on December 31, 2026, (ii) reduce the exercise price of the Warrant from $2.00 to $1.00 per share, and (iii) revise the method of determining the number of shares of Common Stock issuable upon a cashless exercise of the Warrant such that the number of shares of Common Stock issuable upon cashless exercise will be determined by reference, where applicable, to the lowest VWAP on the five (5) trading days immediately preceding the date on which the notice of exercise is submitted to the Company, rather than the VWAP on the day immediately preceding the date on which the notice of exercise is submitted. No proportional adjustment to the number of shares of Common Stock issuable upon exercise of the Warrants was made as a result of the Warrant Amendment.

The descriptions of the terms of the Warrant contained in Item 1.01 of the Prior 8-K are incorporated herein by reference. In addition, the foregoing summary of the Warrant Amendment does not purport to be complete and is subject to, and qualified in its entirety by, the Warrant Amendment, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.
