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.
Corning Inc earns a B (Sound & dependable) forensic quality grade, and its balance-sheet distress test reads 10.4, placing it in the Safe zone. 3 forensic signals were flagged in its latest SEC filings, led by accruals ratio (% of noa).
What the filings flag
+15.1%
FY2024→FY2025
Accruals ratio (% of NOA).Net operating assets grew +15.1% 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 faster than is comfortable — part of profit is sitting in the balance sheet rather than turning to cash. The build is led by receivables up +35% against revenue +19% and inventory up +13% against +13% in cost of sales. A cash-flow measure on the same base disagrees: reported earnings ran behind operating cash by 6% of net operating assets, against an accruals ratio of 15.1%. 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.
7.9%
FY2025
Return on invested capital.Return on invested capital is 7.9% in the latest fiscal year and rising across FY2023–FY2025 from 3%. The capital base behind it barely moved across FY2023–FY2025 ($22.7B to $24.6B, +8%), so there has been little new capital for that return to be earned on.
+0.7%/yr
FY2023–FY2025
Share count.Diluted share count changed +1% over the last 2 years to FY2025 (+0.7%/yr). Roughly flat — buybacks ($163M) are about offsetting stock comp ($286M), not shrinking the count. Per-share value isn't being meaningfully helped or hurt by the count.
