Welcome to our dedicated page for Siga Technologie SEC filings (Ticker: SIGA), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
SIGA Technologies Inc. filings document the formal disclosure record for a commercial-stage pharmaceutical company whose business is centered on TPOXX (tecovirimat) and infectious-disease countermeasures for orthopoxviruses. Recent Form 8-K reports furnish operating results and business updates tied to oral and IV TPOXX revenue, product deliveries, research and development revenue, procurement activity, and BARDA-supported development work.
The filing record also includes special cash dividend disclosures and definitive proxy materials for annual meeting matters. These documents cover common-stock capital actions, board and governance proposals, stockholder voting procedures, earnings press release exhibits, and other Exchange Act reporting events.
SIGA Technologies describes its biodefense-focused pharmaceutical business built around TPOXX, an antiviral for smallpox and related orthopox viruses, sold mainly to governments. The company’s core U.S. revenue base is a BARDA contract contemplating up to approximately $630 million of payments for oral and IV TPOXX, pediatric and post‑marketing work.
SIGA also reports sales to the U.S. Department of Defense of about $10 million in 2024 and international oral TPOXX revenue of $5.8 million in 2025, versus $23.0 million in 2024. Future growth depends heavily on new U.S. stockpiling contracts and recurring non‑U.S. government demand.
The filing highlights regulatory risk: European and U.K. approvals for Tecovirimat‑SIGA were granted under “exceptional circumstances” and are undergoing annual reassessment after mpox trials (PALM007, STOMP, UNITY) failed to show statistically significant efficacy on primary endpoints. The CHMP is expected to decide in March whether to maintain, modify, suspend, or withdraw indications, which could reduce mpox‑related revenue. SIGA notes a broad global patent estate on TPOXX with key protections extending into the 2030s and an employee base of 49 as of February 13, 2026.
SIGA Technologies reported sharply lower results for 2025 but remained profitable. Total revenues were $94.6 million, down from $138.7 million in 2024, as product sales declined to $88.0 million from $133.3 million. Net income fell to $23.3 million, with diluted earnings per share of $0.32 versus $0.82 a year earlier.
Management highlighted $27 million of additional U.S. government funding secured in 2025 to support development and a $13 million oral TPOXX procurement order from an Asia Pacific customer received in January 2026. The balance sheet showed $154.9 million in cash and cash equivalents as of December 31, 2025 and total stockholders’ equity of $198.8 million.
SIGA Technologies Chief Executive Officer Diem Nguyen reported equity compensation activity involving restricted stock units and common shares. On January 27, 2026, 55,902 restricted stock units vested and converted into the same number of common shares at an exercise price of $0 per share.
To cover tax withholding related to this vesting, the issuer withheld 22,804 common shares at $6.82 per share, reducing Nguyen’s directly held common shares to 100,751. Following these transactions, Nguyen also held 55,903 restricted stock units, which continue to vest in equal annual installments over three years from the January 27, 2024 grant date.
SIGA Technologies (SIGA) reported Q3 2025 results showing lower quarterly activity amid timing of product deliveries. Revenue was $2.62 million, down from $10.01 million a year ago, with no point‑in‑time product delivery recognized in the quarter and $1.73 million from research and development services.
The quarter posted a net loss of $6.37 million versus net income of $1.34 million last year, reflecting higher self‑funded R&D and lower sales. Year to date, performance remains strong: nine‑month revenue was $90.78 million (vs. $57.25 million) and net income was $28.71 million (vs. $13.45 million). Cash and cash equivalents were $171.96 million as of September 30, 2025, after paying a $0.60 per share special dividend on May 15, 2025.
Under the 19C BARDA Contract, the company cites up to approximately $630 million of contemplated payments, with $79.1 million of 2025 revenue recognized at a point in time through September 30. The EMA initiated a referral to review Tecovirimat‑SIGA following mixed mpox trial readouts; approvals in other markets remain as stated. As of October 24, 2025, 71,611,302 shares were outstanding.

On November 6, 2025, the company issued an earnings press release describing its quarterly performance, which is furnished as Exhibit 99.1 to this report and incorporated by reference.
