Upturn Advisory & Investor View for BOLT

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

Bolt Biotherapeutics is a clinical-stage biotechnology company developing immuno-oncology therapies using its proprietary Boltbody ISAC platform. Its primary strength lies in a differentiated mechanism of action that aims to activate the innate immune system against solid tumors. The core investment story centers on the success of its lead candidate, BDTX-1535, as it advances through clinical trials. However, the company faces significant risks including potential clinical trial failures, high cash burn, and intense competition from much larger pharmaceutical firms. The stock is best suited for aggressive, growth-oriented investors capable of managing the extreme volatility associated with the biotech development cycle and clinical data reporting.

Upturn Scorecard

Upturn Star Rating

★★★★★
BOLT receives a 3-star rating based on the available scored pillars. The rating is constrained by weak unit economics, and weak price momentum.

Company Fundamentals

★★★★★
BOLT has moderate overall fundamentals (3 stars), with moderate financial health, solid growth momentum, and moderate ownership. In FY2025 versus FY2024, strong earnings growth (+47.1%) is partially offset by weak cash generation (FCF margin -518.8%), moderate revenue growth (+0.1%), weak profitability (net margin -433.7%).

Financial Health Rating

★★★★★
BOLT's financial health is supported by moderate liquidity, including working-capital and asset support (WC/assets 38.5%). Cash strength is soft (2 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
Earnings growth is BOLT's strongest growth driver at +47.1% FY2025 versus FY2024 (strong, 5 stars). By comparison, free-cash-flow growth (+34.9%, solid) is also solid, while revenue growth (+0.1%, moderate) holds the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 27.9% (moderate) and 84.2% of outstanding shares are publicly tradable (strong). Insider ownership of 3.46% provides only moderate management-shareholder alignment.

Top 5 Institutional Investors

Sofinnova Ventures 7.15%
Renaissance Technologies Corp 4.01%
Vivo Capital, LLC 3.76%
Citadel Advisors Llc 2.95%
T3 Companies, LLC 1.97%

Unit Economics (Per $1K Revenue)

★★★★★
BOLT generates approximately $806 of gross profit, $-4,501 of operating income, and $-5,188 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Operating losses and cash burn explain the 1-star rating, with weak cash conversion and weak capital efficiency.

Economic Dimensions

★★★★★
Effective Tax Rate: 0.00%

Quantitative Style Profile

★★★★★
BOLT has a liquid profile. Weak momentum is the primary drawback.
