Upturn Advisory & Investor View for ASPN

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

Aspen Aerogels is a growth-stage company specialized in high-performance aerogel-based insulation for both industrial energy and electric vehicle (EV) markets. The stock offers a strong growth story centered on its essential role in EV battery fire mitigation. The company has a leading position in proprietary aerogel manufacturing, which supports its high-performance product claims. However, it faces significant risks including high customer concentration, historical lack of profitability, and the constant need for capital-intensive production scaling. The stock is best suited for growth-oriented investors with high risk tolerance. Investors should closely monitor automotive production trends and the company’s progress in achieving sustained margin expansion as its new facilities ramp up.

Upturn Star Rating

★★★★★
ASPN receives a 3-star rating, supported by solid analyst coverage. The rating is constrained by weak unit economics, soft quantitative characteristics, and weak price momentum.

Financial Health Rating

★★★★★
ASPN's financial health is supported by solid liquidity, including working-capital and asset support (WC/assets 44.3%). Profitability is moderate (3 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
