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). 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.
Amprius Technologies, Inc. earns a D (Weak — demands caution) forensic quality grade, and its balance-sheet distress test reads 10.6, placing it in the Safe zone. 5 forensic signals were flagged in its latest SEC filings, led by receivables vs revenue.
What the filings flag
73d DSO
FY2024→FY2025
Receivables vs revenue.Days sales outstanding moved from 52 to 73 days FY2024→FY2025 (receivables +325% vs revenue +202%). Receivables are outrunning sales — a flag for aggressive revenue recognition or slipping collections. Across FY2023–FY2025 the day count ran 40 → 52 → 73 days — the latest step continues a climb that was already under way, which is the persistence that separates a collection problem from a busy quarter. Deferred revenue was roughly flat (-94%) over the same period, which doesn't corroborate a benign upfront-billing explanation for the receivables build. Measured against the same quarter twelve months earlier — like-for-like on the calendar, so an ordinary seasonal build cannot produce it — receivables took longer to collect in 7 consecutive quarters (Dec 2024 +19, Mar 2025 +27, Jun 2025 +18, Sep 2025 +40, Dec 2025 +38, Mar 2026 +28, Jun 2026 +44 days). In the latest of them the receivable balance grew +278% against sales +126%, so more of a quarter's billings were still outstanding at the period end than a year earlier — money the company has recognized and not yet been paid.
-75.9%
FY2025
Return on invested capital.Return on invested capital is -75.9% in the latest fiscal year and rising from -217% — well below its ~9% cost of capital, so reinvested dollars may be destroying value, not building it.
+20.4%/yr
FY2022–FY2025
Share-count dilution.Diluted share count changed +75% over the last 3 years to FY2025 (+20.4%/yr). The count is growing: more stock was issued than repurchased over this window, so aggregate results grew faster than their per-share equivalents. That's ~20.4% 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 FY2022 has been diluted ~43%.

FY2025
Stock-based comp load.Stock-based compensation ran 10% of revenue in FY2025 — about $0.06 per diluted share. The cost of it is not in the cash flow — no cash left the business — it is in the count: holders gave up about 20.5% of the company a year, and that rate is not falling. That is the figure to weigh, not the share of free cash flow.
38d
FY2024→FY2025
Inventory days.Days inventory outstanding moved from 31 to 38 FY2024→FY2025 (against cost of goods sold; inventory +2% vs +52% in cost of sales). Inventory is building a little faster than sales — watch for markdowns.
