James E. Flynn and Deerfield Entities Report 9.99% Stake in BiomX Inc. Following Share Count Changes

This Amendment No. 5 to Schedule 13D, filed on April 15, 2026, reports an update to the beneficial ownership of BiomX Inc. (PHGE) by James E. Flynn and associated Deerfield entities. The reporting group, which includes Deerfield Private Design Fund V, L.P., Deerfield Healthcare Innovations Fund II, L.P., and Deerfield Management Company, L.P., reports aggregate beneficial ownership of 989,056 shares, representing 9.99% of the common stock. This total includes 131,270 shares of common stock held directly by the funds, 504,812 shares issuable upon conversion of Series X Preferred Stock, 352,452 shares underlying warrants, and 522 shares issuable upon exercise of options. The primary purpose of this amendment is to reflect a change in the percentage of ownership resulting from a change in the total number of shares outstanding, following equity issuances by the company on April 10 and April 13, 2026. The reporting persons are subject to a 9.99% Beneficial Ownership Limitation, which restricts the conversion of preferred stock and exercise of warrants beyond this threshold. No transactions were executed by the reporting persons in the 60 days preceding the filing.
