Rhea-AI Filing Summary

Armata Pharmaceuticals filed a Form S-8 to register an additional 1,811,295 shares of common stock for issuance under its 2016 Equity Incentive Plan and 2016 Employee Stock Purchase Plan. The shares break down into 1,809,153 shares added under the Equity Incentive Plan and 2,142 shares under the ESPP pursuant to annual "evergreen" provisions that operate from January 1, 2017 through January 1, 2026. The filing incorporates prior S-8 registration statements and recent SEC filings, including the Annual Report for the year ended December 31, 2024 and quarterly reports for March 31, 2025 and June 30, 2025. The Registration Statement was signed on August 13, 2025 by Chief Executive Officer Deborah L. Birx.

Positive
  • Registers an additional 1,811,295 shares for employee compensation plans, maintaining capacity for equity awards
  • Confirms evergreen provisions under both the 2016 Equity Incentive Plan and the 2016 ESPP through January 1, 2026, enabling automatic annual increases
Negative
  • None.

Insights

TL;DR: Routine S-8 registration adds 1.81M shares to support employee compensation; no earnings or transactional changes disclosed.

The filing is a standard update to employee equity capacity, registering 1,811,295 additional shares under existing plans. The majority (1,809,153) arises from the Equity Incentive Plan's evergreen formula and 2,142 from the ESPP’s annual cap. The statement incorporates recent SEC filings, but contains no new financial results, debt changes, or material transactions that would immediately affect valuation.

TL;DR: Governance mechanics intact: board-authorized evergreen increases and standard incorporation-by-reference of prior filings.

The document relies on General Instruction E to add shares for existing employee plans and references the evergreen provisions that automatically increase authorized shares annually through January 1, 2026. Signatures and a power of attorney are included, with the CEO certifying the filing on August 13, 2025. This is a procedural governance filing rather than a corporate-control or compensation-policy change.
