Acelyrin, Inc. (SLRN) Economic Moat Analysis (2026)

Invetso Score: 2/10 — Weak · Last Updated: 2026-08-01

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.
