Upturn Advisory & Investor View for HDSN

09/25/2026: HDSN (1-star) is currently NOT-A-BUY. Pass it for now.

Hudson Technologies is a specialized environmental services company that manages the lifecycle of refrigerants used in HVAC/R systems. The company holds a distinct position by reclaiming used gases and returning them to high purity levels, effectively creating a sustainable supply in a market governed by tightening environmental regulations. Its primary growth story is tied to federal refrigerant phase-down mandates that limit virgin gas availability. Key risks include exposure to volatile refrigerant commodity prices and potential technological shifts in cooling systems. The stock may best suit growth-oriented investors who are comfortable with commodity-cycle sensitivity, noting that the company does not currently provide a dividend for income-focused portfolios.

Upturn Scorecard

Upturn Star Rating

★★★★★
HDSN receives a 3-star rating, supported by available scored pillars. The rating is constrained by weak unit economics, and weak price momentum.

Company Fundamentals

★★★★★
HDSN has moderate overall fundamentals (3 stars), with moderate financial health, soft growth momentum, and strong ownership. In FY2025 versus FY2024, growth and ownership metrics are mixed: negative earnings growth (-31.7%), soft cash generation (FCF margin -3.3%), moderate revenue growth (+4.0%).

Financial Health Rating

★★★★★
HDSN's financial health is supported by solid liquidity, including working-capital and asset support (WC/assets 45.9%). Profitability is soft (2 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
Revenue growth is HDSN's strongest growth driver at +4.0% FY2025 versus FY2024 (moderate, 3 stars). By comparison, while earnings growth (-31.7%, negative) and free-cash-flow growth (-109.5%, negative) hold the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 80.3% and approximately 78.0% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 13.70% supports management-shareholder alignment.

Economic Dimensions

★★★★★
Effective Tax Rate: 26.55%

Quantitative Style Profile

★★★★★
