BiomX Inc. is cutting its outstanding share count from approximately 27.3 million to approximately 2.7 million through a one-for-ten reverse stock split that takes effect at 12:01 a.m. Eastern Time on September 9, 2026, on the NYSE American. The ratio is fixed and stockholder approval is in hand. The filing that landed August 28 was an amendment, and it exists because fractional share treatment for investors holding in street name is less uniform than the headline action implies.
Stockholders approved the reverse split at a special meeting on August 25, authorizing the Board to apply any ratio between one-for-five and one-for-twenty. The Board fixed one-for-ten. It acted by unanimous written consent on August 28, the same day the company filed the original Current Report. Authorized shares also contract, from 750 million to 150 million, once Delaware accepts the Certificate of Amendment. The stock picks up a new CUSIP, 09090D 608, and trades on a split-adjusted basis from the open on September 9. Proportionate adjustments apply to outstanding warrants, convertible instruments and equity awards. Par value per share stays at $0.0001.
Fractional share treatment diverges by holding type
The read-through on fractional mechanics is where the amendment earns its filing. Holders of record who would otherwise receive a fractional share are entitled to one whole share, with rounding applied at the record holder level. For shares held through The Depository Trust Company, rounding applies at the DTC participant level, not at the individual beneficial owner level. BiomX states it will not issue additional whole shares to cover fractional interests held by individual beneficial owners. Retail investors holding in street name should contact their bank, broker or nominee directly for specifics on how their position will be adjusted.
The counterargument is that this structure is unremarkable. Reverse splits processed through DTC routinely handle fractional interests at the participant level, and the amendment reads as a transparency exercise rather than a signal on the mechanics. Continental Stock Transfer and Trust Company is acting as exchange agent; record holders with questions can reach Continental at (212) 509-4000.
On balance, the action is settled. The line to watch is broker-level execution on September 9, when the rounding policies of DTC participants will determine whether some beneficial owners receive a different outcome than holders of record.
