This free snapshot doesn't read filing or proxy text, so the auditor-quality and governance checks that can lower a grade were not evaluated (red flags, auditor quality, say on pay, board independence, going concern, valuation). Those checks only ever lower a grade, so the full analysis can land below the grade above but never above it — treat it as the most favourable reading, not the settled one.
Sionna Therapeutics, Inc. earns a D (Weak — demands caution) forensic quality grade, and its balance-sheet distress test reads 12.8, placing it in the Grey zone. 2 forensic signals were flagged in its latest SEC filings, led by accruals ratio (% of noa).
What the filings flag
+63.4%
FY2024→FY2025
Accruals ratio (% of NOA).Net operating assets grew +63.4% relative to their own average in FY2025 — scaled by NOA itself, not by total assets, which is what the Forensic Screens card's own accrual row divides by. Accruals are building sharply — a large slice of profit sits in operating assets, not cash. An accrual is a claim that still has to be collected or written down, so the gap resolves in a later period whichever way it goes. A cash-flow measure on the same base disagrees: reported earnings ran in line with operating cash by 5% of net operating assets, against an accruals ratio of 63.4%. The two are computed differently: the accruals ratio is the change in net operating assets over average net operating assets, while the cash-flow figure is net income less operating cash flow over that same average. Read them as two results, not one.
n/m (stock split)
FY2024–FY2025
Share count (stock split).Diluted share count changed +936% over the last 1 year to FY2025, but that includes a large one-time change around FY2025 consistent with a stock split or reverse split, not gradual buybacks or issuance — a split changes the count with NO effect on any holder's proportional ownership, so the raw +935.6%/yr figure isn't a real buyback/dilution read here.
