Upturn Advisory & Investor View for PASG

10/30/2026: PASG (1-star) is currently NOT-A-BUY. Pass it for now.

Passage Bio is a clinical-stage biotechnology company focused on developing AAV-based gene therapies for rare central nervous system disorders. Its primary strength lies in a deep research partnership with the University of Pennsylvania, providing a stable foundation for its therapeutic pipeline. The investment story centers on the potential to bring life-changing, one-time treatments to patients with significant unmet needs. However, the company faces substantial risks, including the inherent uncertainty of clinical trials, lack of current revenue, and the necessity of further capital raises. It is best suited for speculative investors comfortable with high risk and long-term development cycles, with close monitoring of clinical data readouts essential.

Upturn Scorecard

Upturn Star Rating

★★★★★
PASG receives a 3-star rating, supported by solid company fundamentals. The rating is constrained by weak unit economics, and weak price momentum.

Company Fundamentals

★★★★★
PASG has solid overall fundamentals (4 stars), with moderate financial health, solid growth momentum, and solid ownership. In FY2025 versus FY2024, solid earnings growth (+29.7%) is partially offset by soft cash generation (FCF margin 0.0%), slightly negative revenue growth (+0.0%), soft profitability (net margin 0.0%).

Financial Health Rating

★★★★★
PASG's financial health is supported by strong efficiency, including operating-expense and cost-of-revenue discipline (opex 0.0% of revenue). Profitability is weak (1 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
Free-cash-flow growth is PASG's strongest growth driver at +34.3% FY2025 versus FY2024 (solid, 4 stars). By comparison, earnings growth (+29.7%, solid) is also solid, while revenue growth (+0.0%, slightly negative) holds the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 46.3% and approximately 99.6% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 7.71% supports management-shareholder alignment.

Unit Economics (Per $1K Revenue)

★★★★★
PASG generates approximately $-0 of gross profit, $-0 of operating income, and $-0 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Weak margins explain the 1-star rating, with weak cash conversion and weak capital efficiency.

Economic Dimensions

★★★★★
Effective Tax Rate: 0.00%

Quantitative Style Profile

★★★★★
PASG has a liquid profile. Weak momentum is the primary drawback, while elevated volatility.
