One-for-ten is the ratio BiomX Inc. (PHGE) fixed for its reverse stock split, a consolidation taking approximately 26.7 million outstanding common shares to approximately 2.7 million. The math reconciles: every ten shares issued immediately before the effective time combine into one, par value unchanged at $0.0001 per share. Split-adjusted trading on NYSE American is expected to begin when markets open on September 9, 2026.
Board authorization and timeline
Stockholders cleared the structure at a special meeting on August 25, 2026, approving an amendment to BiomX's Amended and Restated Certificate of Incorporation. That approval authorized the board to implement any reverse split ratio between 1-for-5 and 1-for-20, and specified that authorized shares would fall from 750,000,000 to 150,000,000 upon the split taking effect. Three days later, the board acted by unanimous written consent on August 28 to fix the ratio at 1-for-10 and set the effective time, filing the Item 8.01 current report the same day.
BiomX expects to file the Certificate of Amendment with the Delaware Secretary of State, with the amendment to become effective at 12:01 a.m. Eastern on September 9. The company will separately report the certificate's effectiveness under Item 5.03 of Form 8-K. Chief Executive Officer Michael Oster signed the August 28 filing.
