Armata Pharmaceuticals Announces Fourth Quarter and Full-Year 2025 Financial Results

LOS ANGELES, California, March 25, 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 financial results for its fourth quarter and full-year ended December 31, 2025.

Fourth Quarter 2025 Financial Results

Grant Revenue. The Company recognized grant revenue of $1.1 million for the three months ended December 31, 2025 as compared to $1.2 million in the comparable period in 2024, which represents MTEC's share of the costs incurred for the Company's AP-SA02 program for the treatment of Staphylococcus aureus bacteremia.

Research and Development. Research and development expenses for the three months ended December 31, 2025 were approximately $6.1 million as compared to approximately $8.5 million for the comparable period in 2024. The decrease was primarily driven by lower clinical trial activity, including reduced spend on AP-PA02 and AP-SA02 programs, as well as lower personnel-related costs compared to the prior year period.

General and Administrative. General and administrative expenses for the three months ended December 31, 2025 were approximately $3.4 million as compared to approximately $3.3 million for the comparable period in 2024. The increase was mainly related to an increase of $0.2 million in legal expenses during the fourth quarter of 2025, offset in part by a decrease of $0.1 million in lease expense.

Impairment Expenses. During the year ended December 31, 2025, we recognized a $5.4 million impairment expense related to our office and research and development space under a non-cancelable operating lease in Marina del Rey, California. The impairment resulted from changes in the anticipated timeline in our plan to sublease the vacated space. There was no impairment of long-lived assets during the year ended December 31, 2024.

Loss from Operations. Loss from operations for the three months ended December 31, 2025 was approximately $13.8 million as compared to a loss from operations of approximately $10.5 million for the comparable period in 2024. The increase in operating loss was primarily driven by the $5.4 million impairment charge recognized in the current period, partially offset by lower research and development expenses.

Net Income (Loss). The net loss for the fourth quarter of 2025 was $124.3 million, or $(3.42) per share on a basic and diluted basis, as compared to a net income of $2.6 million, or $0.07 per share on a basic and $(0.23) per share on a diluted basis, for the comparable period in 2024. The net loss for the quarter ended December 31, 2025 included non-cash loss from the changes in fair value of convertible loan of $105.8 million, as compared to a non-cash gain from the changes in fair value of convertible loan of $14.2 million for the comparable period in 2024, non-cash impairment expense of $5.4 million and non-cash gain from debt extinguishment of $2.2 million for the comparable period in 2024.

Cash and Equivalents. As of December 31, 2025, Armata held approximately $14.1 million of cash and cash equivalents and restricted cash, as compared to $14.8 million as of December 31, 2024.

On January 23, 2026, Armata entered into amendments to the March 2025 Credit Agreement, the 2024 Credit Agreement, the 2023 Credit Agreement, and the Convertible Credit Agreement with Innoviva Strategic Opportunities LLC, extending the maturity dates to June 1, 2027. In addition, the Company amended certain outstanding Innoviva warrants to extend their expiration dates to January 26, 2031, and amended the related voting agreement to align with the revised warrant expiration date or FDA approval, as applicable.

The Company's audited financial statements for the year ended December 31, 2025, included in its Annual Report on Form 10-K, contain an audit opinion from its independent registered public accounting firm that includes an explanatory paragraph relating to the Company's ability to continue as a going concern. This announcement is made pursuant to the disclosure requirements of NYSE American Company Guide Sections 401(h) and 610(b).

As of March 18, 2026, there were approximately 36.6 million common shares outstanding.
