Upturn Advisory & Investor View for SIGA

09/28/2026: SIGA (1-star) is currently NOT-A-BUY. Pass it for now.

SIGA Technologies is a specialized biotechnology company known for TPOXX, the only FDA-approved antiviral treatment for smallpox. Its business model is defined by long-term procurement contracts with the U.S. government, providing strong operating margins but creating high revenue concentration risk. While the company holds a leading position in the niche biodefense market, its growth is cyclical and tied to international pandemic preparedness and contract renewals. Potential investors should weigh the benefits of this unique government-backed revenue against risks like product dependency and political uncertainty. SIGA may suit investors looking for exposure to biodefense themes, though its performance remains subject to significant volatility and the unpredictable nature of global health crises.

Upturn Scorecard

Upturn Star Rating

★★★★★
SIGA receives a 4-star rating, supported by strong unit economics, and solid company fundamentals. The rating is constrained by weak price momentum.

Company Fundamentals

★★★★★
SIGA has solid overall fundamentals (4 stars), with solid financial health, soft growth momentum, and solid ownership. In FY2025 versus FY2024, strong cash generation (FCF margin 45.6%) and strong profitability (net margin 24.6%) are partially offset by negative earnings growth (-60.7%), negative revenue growth (-31.8%).

Financial Health Rating

★★★★★
SIGA's financial health is supported by strong liquidity, including working-capital and asset support (WC/assets 88.8%). Operating efficiency is solid (4 stars), which helps explain the 4-star overall score.

Growth Momentum Score

★★★★★
SIGA's growth profile is soft, with the least-weak measure being free-cash-flow growth at -11.5% FY2025 versus FY2024. By comparison, while revenue growth (-31.8%, negative) and earnings growth (-60.7%, negative) hold the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 50.4% and approximately 57.2% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 42.73% supports management-shareholder alignment.

AltraVue Capital, LLC 3.24%
Vanguard Capital Management, LLC 2.39%
Arrowstreet Capital Limited Partnership 2.12%

Unit Economics (Per $1K Revenue)

★★★★★
SIGA generates approximately $686 of gross profit, $251 of operating income, and $456 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Strong margins, cash conversion, and capital efficiency support the rating.

Economic Dimensions

★★★★★
Effective Tax Rate: 23.36%

Quantitative Style Profile

★★★★★
SIGA has a liquid profile. Weak momentum is the primary drawback.
