SLRN
Acelyrin, Inc. (SLRN) Economic Moat Analysis (2026)
Overall Score
Profitability Returns
TTM margins are still 0 across gross, operating, EBITDA, pretax, and net profit, indicating no current operating profitability.
Returns remain deeply negative, with ROA at -50.5%, ROE at -44.5%, and ROIC at -68.1%.
Balance Sheet Liquidity
Liquidity remains very strong with a current ratio of 18.1x and cash ratio of 2.78x.
Leverage is minimal, with debt-to-equity at 0.014 and debt-to-assets at 0.013, but solvency remains weak given the negative solvency ratio and ongoing losses.
Cash Generation
Operating cash flow and free cash flow are both negative, with FCF at -$305.2M and FCF yield at -133.2%.
Cash conversion remains highly unfavorable, reflected in negative operating cash flow ratios and a cash conversion cycle of -4,217.8 days driven by payables dynamics.
Valuation Market Position
The stock trades at a low price-to-book ratio of 0.49 and price-to-fair-value ratio of 0.49, suggesting a discounted valuation.
However, the business still lacks evidence of durable moat power because revenue, earnings, and cash flow remain negative or absent in the TTM data.
