Upturn Advisory & Investor View for SLN

09/25/2026: SLN (2-star) is currently NOT-A-BUY. Pass it for now.

Silence Therapeutics is a clinical-stage biotechnology company that specializes in developing siRNA-based gene silencing therapies for cardiovascular and hematological conditions. The company's core strength lies in its mRNAi GOLD platform, which enables precise drug delivery to the liver, validated through several strategic partnerships with major pharmaceutical players. While these collaborations offer significant long-term growth opportunities, the company carries substantial execution and clinical development risks, as it currently lacks commercialized products. The stock is best suited for risk-tolerant investors looking for exposure to genetic medicine, with key developments to monitor including clinical data readouts and ongoing partnership milestones.

Upturn Scorecard

Upturn Star Rating

★★★★★
SLN receives a 3-star rating, supported by solid analyst coverage. The rating is constrained by soft unit economics, soft company fundamentals, and soft quantitative characteristics.

Company Fundamentals

★★★★★
SLN has soft overall fundamentals (2 stars), with soft financial health, weak growth momentum, and solid ownership. In FY2025 versus FY2024, growth and ownership metrics are mixed: negative earnings growth (-95.6%), soft cash generation (FCF margin -11149.6%), negative revenue growth (-98.7%).

Financial Health Rating

★★★★★
SLN's financial health is supported by moderate liquidity, including working-capital and asset support (WC/assets 79.9%). Cash strength is soft (2 stars), which helps explain the 2-star overall score.

Growth Momentum Score

★★★★★
SLN's growth profile is soft, with the least-weak measure being free-cash-flow growth at -15.0% FY2025 versus FY2024. By comparison, while revenue growth (-98.7%, negative) and earnings growth (-95.6%, negative) hold the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 39.7% and approximately 60.9% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 7.97% supports management-shareholder alignment.
