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.
Amtech Systems Inc earns a D (Weak — demands caution) forensic quality grade, and its balance-sheet distress test reads 5.3, placing it in the Safe zone. 4 forensic signals were flagged in its latest SEC filings, led by return on invested capital.
What the filings flag
-41.2%
FY2025
Return on invested capital.Return on invested capital is -41.2% in the latest fiscal year, against -12.3% in FY2023, having run between -41.2% and -6.0% across FY2023–FY2025 with no direction held. After-tax operating profit was ($12M) in FY2023 and ($23M) in FY2025, with operating income at -13.2% of revenue in FY2023, -6.6% in FY2024 and -35.9% in FY2025. The capital base behind it came down -43% across FY2023–FY2025, from $96M to $55M, so this is a return struck on a smaller base rather than a record of money put to work. FY2025's operating profit carried a $20M goodwill write-off that alone took about 29.4 points off that year's return, so more than the whole 28.9-point fall across FY2023–FY2025 is that charge landing in the latest year rather than the capital earning less. FY2024's operating profit carried a $6M goodwill write-off that alone took about 5.7 points off that year's return; FY2024 sits between the two ends of FY2023–FY2025, so the charge shapes the path between them without moving the change across it.
91d DSO
FY2024→FY2025
Receivables vs revenue.Days sales outstanding moved from 79 to 91 days FY2024→FY2025 (receivables -10% vs revenue -22%). Receivables are creeping up relative to sales. Across FY2023–FY2025 the day count ran 85 → 79 → 91 days, so the latest reading sits on top of a record that was flat or falling before it — one year's move, not a direction the business has been travelling in. Both figures are measured on period-end balances rather than the beginning-plus-ending average, because averaging needs the balance a year before every reading — FY2024's opening balance is on file, but across the 3 fiscal years read here (FY2023–FY2025) the average yields only 2 day counts (1 step), too few to tell a climb from one year's move.
