Amtech Systems (ASYS): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 FY26, to Jun 30, 2026, filed Aug 5, 2026; rules v1.1
Amtech Systems (ASYS): 1 rule of 10 triggered on the filings to Jun 30, 2026: FCF growth = the business improved; 3 with insufficient data; 2 not applicable. Each is a question to verify, with the normal explanation that would produce the same figures.
Check these first
FCF growth = the business improved Triggered · severity high · confidence medium
Free cash flow rose $2M (+40%), from $5M to $7M, but capital expenditure fell by $4M: more than the whole increase came from sources that need not repeat. Operating cash flow before working capital fell by $143K.
Innocent reading: An expansion programme finished, so capex fell back to maintenance levels for good.
Every rule
A01 FCF growth = the business improved Triggered severity high · confidence medium
Free cash flow rose $2M (+40%), from $5M to $7M, but capital expenditure fell by $4M: more than the whole increase came from sources that need not repeat. Operating cash flow before working capital fell by $143K.
The figures and how they are read
| Fiscal year before | FY24 |
| Fiscal year | FY25 |
| Operating cash flow, year before | $10M |
| Operating cash flow | $8M |
| Capex, year before | $5M |
| Capex | $950K |
| Free cash flow, year before | $5M |
| Free cash flow | $7M |
| Change in FCF | $2M |
| Change in capex | −$4M |
| Working capital: change in its cash contribution | −$2M |
| Of which: capex cut | $4M |
| Of which: working capital released | 0.00 |
| Share of the increase that need not repeat | +200.1% |
| Operating cash flow before working capital: change | -143000.00 |
FCF = operating cash flow − cash capex; ΔFCF = ΔOCF − ΔCapEx; the working-capital part is the change in the cash-bridge items (receivables, inventory, payables, accruals), with the sign of the cash flow statement
Source: FY25 (cash flow statement, fiscal year) · FY24 (cash flow statement, fiscal year before)
What would explain it innocently
- An expansion programme finished, so capex fell back to maintenance levels for good
- Suppliers agreed longer payment terms in a contract
- Inventory was brought down after a glut and will stay down
What to look for in the filing
- Maintenance capex (what it costs to keep the assets working)
- Supplier payment terms and any supply-chain financing
- Management's capex guidance for next year
What would show the trap does not apply
- Next year's FCF holds or rises with capex back at its earlier level and working capital no longer releasing cash
- The 10-K's capex guidance and the segment capex show the cut is a completed programme, not deferral
- The working-capital release matches a disclosed change in terms or a divestiture, not stretched payables or a collection push
Look again: next filing.

E02 Low P/E at a cyclical peak = undervalued Insufficient data
no market value or trailing net income in the valuation research
E07 A precise DCF value = the true value Insufficient data
no DCF in the valuation research for this company
J06 A bank's low P/E and high profit = safe Not applicable
not a bank
J08 A REIT's low net income = the dividend is unsafe Not applicable
not a REIT
What the statuses mean
Triggered: the filings show the pattern; read the normal explanations and the missing evidence before concluding anything. To review: one quarter or a weak signal; a reader's judgement, not a pattern. Not triggered: the pattern is absent on these figures. Insufficient data: the filings read so far do not hold what the rule needs; this is not a clean bill. Not applicable: the rule is not meant for this kind of company (a bank's working capital, a loss-making quarter's EPS growth). Out of date: the latest filing is more than fifteen months old.
Severity is what the pattern could mean for cash, value or solvency; confidence is how reliable the inputs and the reading are. The two are kept apart.

Every rule and the companies it triggers on → Amtech Systems: cash flow →
Each rule reads the company's own filings by a fixed formula and says what would explain the same figures innocently. A triggered rule is a question to verify, not a finding of manipulation, and not a view on the stock. Missing data is shown as missing, never as clear. Not investment advice.
