Insights
Non-dilutive DoD funding strengthens Armata’s lead phage program heading toward Phase 3.
Armata Pharmaceuticals has secured an additional $2.5 million in non-dilutive U.S. Department of Defense funding, bringing the total award for AP-SA02 development to $28.7 million. This funding supports a late-stage bacteriophage therapy for complicated Staphylococcus aureus bacteremia.
The company states that the incremental funds will cover key activities for Phase 3 readiness of AP-SA02. Management indicates plans to start a Phase 3 superiority study of intravenous AP-SA02 in complicated SAB in the second half of 2026, building on positive Phase 2a diSArm data and existing QIDP and Fast Track designations.
For investors, the combination of substantial non-dilutive backing and a clear Phase 3 timeline reduces near-term financing pressure around this specific program and clarifies development plans. Subsequent company filings and clinical updates will show whether Armata meets the stated Phase 3 initiation window and how the total $28.7 million award translates into trial execution progress.

Exhibit 99.1
Armata Pharmaceuticals Receives $2.5 Million
of Additional Non-Dilutive Award Funding from the
U.S. Department of Defense to Support AP-SA02
Supports Phase 3 readiness of AP-SA02
Non-dilutive DoD funding totals $28.7M to date
LOS ANGELES, Calif., June 23, 2026 -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a late clinical-stage biotechnology company focused on the development of high-purity, pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections, today announced that it has received an additional $2.5 million of non-dilutive funding pursuant to a previously announced Department of Defense (DoD) award, received through the Medical Technology Enterprise Consortium (MTEC) and managed by the Naval Medical Research Command (NMRC) – Naval Advanced Medical Development (NAMD) with funding from the Defense Health Agency and Joint Warfighter Medical Research Program. The award, which now totals $28.7 million, supports the development of Armata’s lead clinical candidate AP-SA02, for adjunct treatment of complicated Staphylococcus aureus (“S. aureus”) bacteremia (“SAB”) caused by methicillin-sensitive S. aureus (“MSSA”) or methicillin resistant S. aureus (“MRSA”). The additional $2.5 million is intended to fund key activities to support Phase 3 readiness of AP-SA02.
“The DoD has been a strong and valued partner in the development of AP-SA02, and we appreciate its continued support for this important program,” said Dr. Deborah Birx, Chief Executive Officer of Armata. “With phage therapy gaining attention globally as a potential tool to combat the growing antimicrobial resistance crisis, DoD support at the federal level is important to ensuring the U.S. contributes to this critical field. We remain focused on moving AP-SA02 efficiently through clinical development with the goal of delivering this novel phage-based therapy to patients in need, including both military and civilian populations.”
“Armata is advancing plans to initiate a Phase 3 superiority study of intravenous AP-SA02 in complicated SAB in the second half of 2026. Principal Investigators at sites around the U.S. continue to express excitement about participating in the Phase 3 study. We believe AP-SA02 has the potential to bring new hope to all patients affected by this common, highly severe, and often deadly infection,” concluded Dr. Birx.
About AP-SA02
Armata is developing AP-SA02, a fixed multi-phage cocktail, for the adjunct treatment of complicated SAB caused by MSSA or MRSA. AP-SA02 has received Qualified Infectious Disease Product (QIDP) and Fast Track designations from the U.S. Food and Drug Administration. Armata’s diSArm study (NCT05184764) was a Phase 1b/2a, multicenter, randomized, double-blind, placebo-controlled, multiple ascending dose escalation study of the safety, tolerability, and efficacy of intravenous AP-SA02 in addition to best available antibiotic therapy (“BAT”) compared to BAT alone (placebo) for the treatment of adults with complicated SAB. Positive results from the Phase 2a diSArm study were highlighted in a late-breaking oral presentation at IDWeek 2025™ in October 2025.
