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 (auditor quality, say on pay, board independence, going concern). 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 an F (Poor — capital at risk) 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.Accruals ratio: the year-over-year change in net operating assets, relative to their own average.NOA (net operating assets): the money tied up in running the business, operating assets minus operating liabilities.
+935.6%/yr
FY2024–FY2025
Share-count dilution.Diluted share count changed +936% over the last 1 year to FY2025 (+935.6%/yr). The count is growing — 3.9M shares in FY2024, 40.0M in FY2025: more stock was issued than repurchased over this window, so aggregate results grew faster than their per-share equivalents. That's ~935.6% shaved off per-share growth every year — total profit has to grow that much just to keep earnings-per-share flat, and a stake held since FY2024 has been diluted ~90%.
