– Funds to be used primarily to advance its lead Pseudomonas aeruginosa candidate, AP-PA02

MARINA DEL REY, Calif.March 30, 2020 /PRNewswire/ — Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections, today announced that, following a vote in favor of the transaction by more than 99% of the Armata shareholders that voted, Armata has completed the closing of the second tranche under the Company’s $25 million Securities Purchase Agreement with Innoviva, Inc. (NASDAQ: INVA) (“Innoviva”), a company with a portfolio of royalties that include respiratory assets partnered with Glaxo Group Limited. In connection with the second closing, Armata issued 7,717,661 common shares, at a price of $2.87 per share, and warrants to purchase 7,717,661 common shares, at an exercise price of $2.87 per share, in exchange for gross proceeds of approximately $22.2 million.

“The completion of our $25 million financing with Innoviva provides our company with significant resources that will allow us to efficiently advance our pipeline of phage-based therapeutics to treat multi-drug resistant bacterial infections,” stated Todd R. Patrick, Chief Executive Officer of Armata. “This is an important year for Armata as we aim to advance two programs into clinical trials, most notably our lead program, AP-PA02, which we are developing to treat lower airway infections caused by Pseudomonas aeruginosa. This pathogen has demonstrated a high level of intrinsic resistance to most antibiotics and has been particularly problematic for cystic fibrosis patients, a challenge that is reflected in our recent announcement that we have been selected for a therapeutics development award of up to $5 million from the Cystic Fibrosis Foundation. We are very pleased to have the support of Innoviva on these important programs.”

The closing of the first tranche of the Innoviva Securities Purchase Agreement, which occurred on February 12, 2020, raised gross proceeds of approximately $2.8 million through the issuance of 993,139 common shares, at a price of $2.87 per share, and warrants to purchase an additional 993,139 common shares, at an exercise price of $2.87 per share. Concurrent with the closing of the first tranche, Innoviva directors Odysseas Kostas, M.D. and Sarah Schlesinger, M.D joined Armata’s Board of Directors.

Armata currently has approximately 18.6 million shares of common stock and warrants exercisable for approximately 10.6 million shares of common stock outstanding.

The Company expects the proceeds from the offering to provide sufficient cash resources to achieve several important milestones in 2020 and 2021.
