Reverse Stock Split. On September 3, 2026, BiomX Inc. (the “Company”) filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the “Split Amendment”) with the Secretary of State of the State of Delaware, which became effective at 12:01 a.m., Eastern Time, on September 9, 2026. The Split Amendment effected a one-for-ten reverse stock split of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and reduced the number of authorized shares of Common Stock from 750,000,000 to 150,000,000. The Split Amendment was approved by the Company’s stockholders at a special meeting held on August 25, 2026, as previously reported. Trading in the Common Stock on a split-adjusted basis on the NYSE American commences with the market open on September 9, 2026 under the new CUSIP number 09090D 608. No fractional shares will be issued; as previously disclosed, fractional shares were rounded up to the nearest whole share at the record holder and DTC participant level.
Name Change. On September 3, 2026, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the “Name Change Amendment”) with the Secretary of State of the State of Delaware, which will become effective at 12:01 a.m., Eastern Time, on September 11, 2026, changing the Company’s name from BiomX Inc. to Tessera Defense and Homeland Security Inc. The Name Change Amendment was approved by the Company’s Board of Directors on August 31, 2026 and, pursuant to Section 242(d)(1) of the Delaware General Corporation Law, did not require stockholder approval. In connection with the name change, the Common Stock will begin trading on the NYSE American under the ticker symbol “HLSQ” at the market open on September 11, 2026. The CUSIP number of the Common Stock, 09090D 608, was not changed by the name change.
The foregoing descriptions of the Split Amendment and the Name Change Amendment do not purport to be complete and are qualified in their entirety by reference to the full text of those amendments, copies of which are filed as Exhibits 3.1 and 3.2 to this Current Report and are incorporated herein by reference.
