Upturn Advisory & Investor View for ASTI

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

Ascent Solar Technologies, Inc. is a small-cap solar company specializing in lightweight, flexible thin-film photovoltaic modules for niche markets. Its main strength lies in its proprietary CIGS technology, which is well-suited for high-margin aerospace and defense applications. The primary investment story centers on the company’s pivot toward these specialized sectors, which could offer more stable, long-term revenue than mass-market solar. However, the firm faces significant risks, including historical financial losses, the need for continued capital, and intense competition. This stock may suit speculative investors who can tolerate high volatility while monitoring progress on key government and industrial contracts.

Upturn Scorecard

Upturn Star Rating

★★★★★
ASTI receives a 2-star rating, supported by available scored pillars. The rating is constrained by weak unit economics, soft quantitative characteristics, and weak price momentum.

Company Fundamentals

★★★★★
ASTI has moderate overall fundamentals (3 stars), with soft financial health, solid growth momentum, and moderate ownership. In FY2025 versus FY2024, solid earnings growth (+14.2%) and strong revenue growth (+83.3%) are partially offset by soft cash generation (FCF margin -9034.4%), soft profitability (net margin -10202.5%), very low insider ownership of 0.28%.

Financial Health Rating

★★★★★
ASTI's financial health is supported by moderate liquidity, including working-capital and asset support (WC/assets 18.6%). Operating efficiency is weak (1 stars), which helps explain the 2-star overall score.

Growth Momentum Score

★★★★★
Revenue growth is ASTI's strongest growth driver at +83.3% FY2025 versus FY2024 (strong, 5 stars). Earnings growth (+14.2%, solid) and free-cash-flow growth (+17.7%, solid) are also constructive, though not equally high across every growth measure.

Ownership

★★★★★
Institutional ownership is 25.8% and approximately 94.9% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership is only 0.28%, which materially reduces the ownership score.

DnB NOR Asset Management (Asia) 2.70%
Arosa Capital Management LP 1.53%
UBS Group AG 1.51%
Vanguard Capital Management, LLC 0.91%

Unit Economics (Per $1K Revenue)

★★★★★
ASTI generates approximately $-1,557 of gross profit, $-102,567 of operating income, and $-90,344 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Strong cash conversion and healthy margins support the rating, although capital efficiency remains below the highest tier.

Economic Dimensions

★★★★★
Effective Tax Rate: 0.00%

Quantitative Style Profile

★★★★★
ASTI has a liquid profile. Weak momentum is the primary drawback, while valuation that is moderately attractive rather than deeply discounted.
