Upturn Advisory & Investor View for NAII

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

Natural Alternatives International, Inc. is a long-standing contract manufacturer and ingredient provider for the global health and wellness industry. The company distinguishes itself through its scientific rigor and proprietary licensing of ingredients like CarnoSyn, which helps provide stable, higher-margin revenue. Its primary investment story centers on its ability to leverage its manufacturing expertise to capture demand from major wellness brands. However, investors must weigh these strengths against risks related to customer concentration, industry-wide pricing pressure, and regulatory sensitivity. This stock may suit value-oriented or income-focused investors who prioritize long-term manufacturing stability and potential dividend returns, while monitoring key contract renewals and R&D successes.

Upturn Star Rating

★★★★★
NAII receives a 2-star rating, reflecting soft or weak scores across the available pillars. The rating is constrained by weak unit economics, soft analyst coverage, and weak price momentum.

Company Fundamentals

★★★★★
NAII has moderate overall fundamentals (3 stars), with soft financial health, soft growth momentum, and solid ownership. In FY2026 versus FY2025, growth and ownership metrics are mixed: negative earnings growth (-52.4%), weak cash generation (FCF margin -8.9%), moderate revenue growth (+9.7%).

Financial Health Rating

★★★★★
NAII's financial health is soft, with the relatively strongest area being moderate liquidity, including working-capital and asset support (WC/assets 0.0%). Profitability is weak (1 stars), which helps explain the 2-star overall score.

Growth Momentum Score

★★★★★
Revenue growth is NAII's strongest growth driver at +9.7% FY2026 versus FY2025 (moderate, 3 stars). By comparison, while earnings growth (-52.4%, negative) and free-cash-flow growth (-644.3%, negative) hold the profile back, so recent growth is not broad-based across the business.

★★★★★
Institutional ownership is 36.3% and approximately 78.6% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 21.68% supports management-shareholder alignment.
