Exhibit 99.1

Armata Pharmaceuticals Announces Fourth Quarter and Full-Year 2024 Results and

Provides Corporate Update

LOS ANGELES, CA, March 20, 2025 - Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a 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 financial results for its fourth quarter and full-year ended December 31, 2024, and provided a corporate update.

Fourth Quarter 2024 and Recent Developments:

Announced encouraging topline results from its Phase 2 Tailwind study evaluating inhaled AP-PA02 as a potential treatment for chronic pulmonary disease; Pseudomonas aeruginosa (“P. aeruginosa” or “P.a.”) infection in non-cystic fibrosis bronchiectasis (“NCFB”) patients.
o The Phase 2 Tailwind study represents the second successful clinical trial for AP-PA02, Armata's lead pulmonary candidate, which was first evaluated in people with cystic fibrosis in the Phase 1b/2a SWARM-P.a. trial that completed in 2023;
o Inhaled AP-PA02 was well-tolerated, with treatment-emergent adverse events mild and self-limiting;
o Post-hoc intent-to-treat analysis demonstrated a statistically significant reduction of P.a. colony forming units (“CFUs”) at one and two weeks post-dosing. Approximately one-third of all subjects treated with phage monotherapy exhibited at least a 2-log CFU reduction in P.a.; and
o Data suggest AP-PA02 alone is as effective as AP-PA02 plus antibiotics in reducing P.a. CFUs in the lungs of NCFB patients, and indicates the potential for phage therapy to reduce reliance on chronic antibiotic use.

Completed enrollment of Phase 1b/2a diSArm study of intravenous (“IV”) AP-SA02 as a potential treatment for Staphylococcus aureus (“S. aureus”) bacteremia.
o Blinded data demonstrates AP-SA02 is well-tolerated following IV administration of up to 5E10 plaque forming units (“PFUs”) every six hours (2E11 PFU every 24 hours) for five days;
o Persistence of AP-SA02 in a subset of complicated bacteremia subjects is consistent with in vivo phage amplification despite 48-72 hours of broad-spectrum IV antibiotics -- unblinding is critical to understand subjects’ clinical presentation;
o Topline data anticipated in the first half of 2025; and
o Anticipate that findings from the diSArm study will inform the design of a pivotal trial strategy to be discussed with the U.S. Food and Drug Administration (the “FDA”) that may enable Armata to obtain agreement on a path to potential approval.

Further advanced bacteriophage science through presentations and publications.
o Presented at 7th Annual Phage Therapy Summit, March 11-13, 2025, Boston, MA;
o Presented at 5th Annual Phage Futures Meeting, November 19, 2024, Boston, MA; and
o Announced structural biology publication in the journal Communications Biology describing a representative phage in Armata's clinical candidate, AP-PA02.

In March 2025, entered into a $10.0 million secured credit agreement with Innoviva Strategic Opportunities LLC, a wholly-owned subsidiary of Innoviva, Armata's principal shareholder.

“During the fourth quarter, we achieved another significant clinical milestone with encouraging topline results from our Phase 2 Tailwind study evaluating inhaled AP-PA02 in NCFB patients as both monotherapy and in combination with inhaled anti-pseudomonal antibiotics,” stated Dr. Deborah Birx, Chief Executive Officer of Armata. “This was the second successful clinical evaluation of AP-PA02 following our Phase 1b/2a SWARM-P.a. trial in cystic fibrosis patients. We believe the learnings gained from the two completed Phase 2 studies position Armata to design a pivotal trial to evaluate AP-PA02 as an alternative to antibiotics in NCFB patients with chronic pulmonary P. aeruginosa infection.”  

“We also completed enrollment of our Phase 1b/2a diSArm study evaluating our high purity phage product candidate, AP-SA02, as a potential treatment for S. aureus bacteremia. We expect to report topline results in the first half of this year, and believe data will provide valuable insights into the safety and tolerability of AP-SA02 at high intravenous doses, and inform the dose and schedule to be studied in a larger efficacy study, which we plan to discuss with the FDA this year.”

“We remain committed to developing a definitive efficacy trial focused on phage as an alternative to broad-spectrum antibiotics and/or antibiotic-sparing to decrease the utilization of traditional antibiotics and their detrimental impact on the normal human microbiome. I believe we are well positioned to achieve value-creating milestones in 2025 as the Armata team continues to work to introduce a novel therapeutic class to help fight the global health crisis of antimicrobial resistance,” Dr. Birx concluded.

Fourth Quarter 2024 Financial Results

Grant Revenue. The Company recognized grant revenue of $1.2 million for the three months ended December 31, 2024 as compared to $1.5 million in the comparable period in 2023, which represents MTEC’s share of the costs incurred for the Company’s AP-SA02 program for the treatment of S. aureus bacteremia.

Research and Development. Research and development expenses for the three months ended December 31, 2024 were approximately $8.5 million as compared to approximately $7.9 million for the comparable period in 2023. The Company continues to invest in clinical-related expenses associated with its primary development programs.

General and Administrative. General and administrative expenses for the three months ended December 31, 2024 were approximately $3.3 million as compared to approximately $3.2 million for the comparable period in 2023. The increase was mainly related to an increase of $0.3 million in personnel related expenses during the fourth quarter of 2024, offset in part by a decrease of $0.2 million in professional services.

Loss from Operations. Loss from operations for the three months ended December 31, 2024 was approximately $10.5 million as compared to a loss from operations of approximately $9.6 million for the comparable period in 2023.

Net Income (Loss). The net income for the fourth quarter of 2024 was $2.6 million, or $0.07 per share on a basic and $(0.23) per share on a diluted basis, as compared to a net loss of $19.8 million, or $(0.55) per share on both a basic and diluted basis, for the comparable period in 2023. The net income for the quarter ended December 31, 2024 included non-cash gain from the changes in fair value of convertible loan of $14.2 million and non-cash gain from debt extinguishment of $2.2 million, as compared to $8.9 million loss from the changes in fair value of convertible loan for the quarter ended December 31, 2023.

Cash and Equivalents. As of December 31, 2024, Armata held approximately $14.8 million of cash and cash equivalents and restricted cash, as compared to $19.2 million as of December 31, 2023.

On March 12, 2025, the Company entered into a credit and security agreement for a loan in an aggregate amount of $10.0 million with Innoviva SO. The loan bears interest at an annual rate of 14% and matures on March 12, 2026. Principal and accrued interest are payable at maturity. The Company and Innoviva also entered into amendments to the three pre-existing credit and security agreements in order to, among other things, extend the maturity dates under such agreements to March 12, 2026.

As of February 28, 2025, there were approximately 36.2 million common shares outstanding.
