Power Integrations (POWI): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 2026, to Sep 30, 2026, filed Nov 5, 2026; rules v1.1
Power Integrations (POWI): 1 rule of 10 triggered on the filings to Sep 30, 2026: FCF growth = the business improved. 1 to review; 2 with insufficient data; 3 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 medium · confidence medium
Free cash flow rose $23M (+36%), from $64M to $87M, but working capital released $19M more cash than the year before: 82% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $11M.
Innocent reading: An expansion programme finished, so capex fell back to maintenance levels for good.
A precise DCF value = the true value To review · confidence high
The DCF's point value is 7.67 a share (price 47.11); 53% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 5.33 to 10.01; across every method the research ran the range is -11 to 110. The value is a range; the decimals are not information.
Innocent reading: A stable, mature business with a narrow range of outcomes, where the point value is a fair summary.

A01 FCF growth = the business improved Triggered severity medium · confidence medium
Free cash flow rose $23M (+36%), from $64M to $87M, but working capital released $19M more cash than the year before: 82% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $11M.
The figures and how they are read
| Fiscal year before | FY2024 |
| Fiscal year | FY2025 |
| Operating cash flow, year before | $81M |
| Operating cash flow | $112M |
| Capex, year before | $17M |
| Capex | $24M |
| Free cash flow, year before | $64M |
| Free cash flow | $87M |
| Change in FCF | $23M |
| Change in capex | $7M |
| Working capital: change in its cash contribution | $19M |
| Of which: capex cut | 0.00 |
| Of which: working capital released | $19M |
| Share of the increase that need not repeat | +82.3% |
| Operating cash flow before working capital: change | 11218000.00 |
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: FY2025 (cash flow statement, fiscal year) · FY2024 (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.
A07 Stock compensation added back = no economic cost Not triggered confidence high
Stock compensation is 8.9% of revenue, but buybacks of $98M covered it (2.5×) and the diluted share count fell 1.4%: the dilution has been paid for in cash.
The figures and how they are read
| Fiscal year | FY2025 |
| Stock compensation | $40M |
| Revenue | $444M |
| SBC / revenue | +8.9% |
| Buybacks | $98M |
| Buybacks / SBC | 2.5 |
| Diluted shares, year before | 57.1M shares |
| Diluted shares | 56.3M shares |
| Diluted shares: change | -1.4% |

B02 Receivables growing = future cash is certain Not triggered confidence medium
Receivables grew -11% against revenue 6% in Q3 2026; DSO 20 against a median of 21: collections are keeping pace with sales.
The figures and how they are read
| Quarter | Q3 2026 |
| Revenue, year over year | +5.5% |
| Receivables, year over year | -11.4% |
| Quarter before | Q2 2026 |
| Revenue y/y, quarter before | +2.7% |
| Receivables y/y, quarter before | -2.9% |
| Days sales outstanding | 20.1 |
| DSO, median of eight quarters | 21.3 |
| Receivables | $28M |
| Revenue | $125M |
receivables and revenue against the same quarter a year earlier; DSO = receivables / quarterly revenue × days, against the median of the eight quarters before
Source: Q3 2026 (receivables and revenue) · Q3 2025 (the same quarter a year earlier)
B08 Adjusted profit = economic profit Insufficient data
no reconciliation table read from the releases yet and fewer than three quarters with both an adjusted and a GAAP EPS
C02 Low net debt = no refinancing risk Insufficient data
no debt figure could be read from the balance sheet (the filing may tag it in other lines)
D03 EPS growth = profit growth Not applicable
a loss in one of the quarters: EPS growth has no meaning
E02 Low P/E at a cyclical peak = undervalued Not triggered confidence medium
Net income of $25M is not at a cyclical high against the last eight years (median $71M, best $193M): the P/E of 106.6× is on a normal year.
The figures and how they are read
| market value | $2.7B |
| net income ttm | $25M |
| pe ttm | 106.60 |
| net income median fy | $71M |
| pe mid cycle | 37.50 |

| down years in window | 4 |
P/E on the trailing twelve months' net income against the P/E on the median net income of the last eight fiscal years (a mid-cycle stand-in); 'at a peak' = this year's profit at or above 90% of the best year and at least 1.3× the median
Source: Q3 2026 (net income, trailing twelve months)
E07 A precise DCF value = the true value To review confidence high
The DCF's point value is 7.67 a share (price 47.11); 53% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 5.33 to 10.01; across every method the research ran the range is -11 to 110. The value is a range; the decimals are not information.
The figures and how they are read
| dcf value | 7.67 |
| price | 47.11 |
| terminal value share | +52.8% |
| swing by input | Operating margin / ±3 pts / 5.33 / 10.01; Revenue growth (each year) / ±5 pts / 7.26 / 8.16; Capex (share of revenue) / ±1 pt / 7.36 / 7.98; WACC / ±1 pt / 7.4 / 8.01 |
| range all methods | -11.42; 110.2 |
the DCF's point value against the share of it that is the terminal value and the value at each input moved by one step (growth ±5 pts, WACC ±1 pt, margin ±3 pts …); the range across every method the research ran

What would explain it innocently
- A stable, mature business with a narrow range of outcomes, where the point value is a fair summary
- The inputs that matter most are themselves well known (a regulated return, a long contract)
What to look for in the filing
- Which input you believe differs from the research's and why
- What the price implies for growth (the reverse DCF on the fair-value page)
What would show the trap does not apply
- The DCF's value is robust to the terminal growth and discount rate (the range's low end is still above the price)
- The company's cash flows over the next three years track the DCF's early years
Look again: next filing.
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 → Power Integrations: cash flow → Earnings quality score →
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.
