Immediately after the effective time of the Acquisition, and before giving effect to the concurrent private placement the former stockholders of BiomX will own approximately 55% and the former stockholders of APT will own approximately 45% of the consolidated entity of BiomX and APT. The Acquisition is expected to close within the next 30 days, subject to the satisfaction of the closing conditions described in the definitive merger agreement.

Concurrently with entering into the definitive merger agreement, BiomX entered into a definitive purchase agreement for the sale of shares of newly created non-voting convertible preferred stock (“Series X Preferred Stock”) and warrants to purchase shares of BiomX common stock in a private placement to certain institutional accredited investors led by affiliates of Deerfield Management Company and the AMR Action Fund, and additional investors including the Cystic Fibrosis Foundation, OrbiMed, and Nantahala Capital. The private placement is expected to result in gross proceeds to BiomX of $50 million before deducting placement agent and other offering expenses. The proceeds from the private placement are expected to provide funding through the results from a planned Phase 2b trial that will evaluate BiomX’s lead product candidate, BX004, for the treatment of chronic pulmonary infections caused by Pseudomonas aeruginosa (P. aeruginosa) in CF patients expected in the third quarter of 2025 and Phase 2 results from APT’s clinical-stage product candidate, now named BX211, for the treatment of Staphylococcus aureus (S. aureus) infections in DFO patients expected in the first quarter of 2025. The private placement is expected to close substantially concurrently with, and subject to the closing of, the Acquisition.

“BiomX’s acquisition of APT will create a leading phage company with diverse technologies and an advanced clinical pipeline,” said Jonathan Leff, Partner and Chairman of the Deerfield Institute at Deerfield Management. “With important data readouts for two programs expected in 2025, the funding from this transaction is designed to provide multiple opportunities to create stockholder value by reaching critical inflection points in each program’s clinical development.”

“Today’s announcement sends a clear vote of confidence from leading biotechnology investors who led this transaction that phage technology holds significant potential to treat serious infections with significant unmet need and limited treatment options,” said Jonathan Solomon, Chief Executive Officer of BiomX. “In the case of CF, BX004 has the potential to improve lung function in patients with chronic and potentially deadly pulmonary infections.”

“APT’s phage therapy for DFO holds the potential to prevent amputations associated with intractable infections that have penetrated into the bone in patients with diabetic foot ulcers,” said Greg Merril, Founder and Board Director of APT. “With the combined intellectual and financial resources coming from this acquisition, we now have a clear line of sight towards applying this ground-breaking technology to reach multiple data readouts in CF and DFO over the next 12-24 months.”

Management and Organization

BiomX will continue to be led by its current management team, with the addition of Michael Billard from APT as General Manager, U.S. Following the transaction, the BiomX board of directors will be comprised of Dr. Russell Greig, Chair of the Board of Directors, and the following members of the board of directors - Dr. Jesse Goodman, Jonathan Leff, Dr. Alan Moses, Greg Merril, Eddie Williams and Jonathan Solomon, BiomX’s Chief Executive Officer.
