Amentum Holdings (AMTM): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 FY26, to Jul 3, 2026, filed Aug 11, 2026; rules v1.1
Amentum Holdings (AMTM): 1 rule of 10 triggered on the filings to Jul 3, 2026: adjusted profit = economic profit. 1 to review; 1 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
Adjusted profit = economic profit Triggered · severity high · confidence low
Adjusted EPS was at least 10% above GAAP in 3 of the last 3 quarters (on average 63% above). Costs excluded every quarter (restructuring, stock compensation, amortisation of acquired intangibles, litigation) are a recurring cost of the business, not a one-off.
Innocent reading: A genuine one-off this year (an impairment, a settlement) that happens to span several quarters.
A precise DCF value = the true value To review · confidence high
The DCF's point value is 27.49 a share (price 21.37); 62% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 2.47 to 52.52; across every method the research ran the range is 5 to 219. 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.
Every rule
A01 FCF growth = the business improved Not triggered confidence medium
Free cash flow rose $480M to $516M; working capital and lower capex explain 0% of it, so most of the gain is in operating cash flow itself.
The figures and how they are read
| Fiscal year before | FY24 |
| Fiscal year | FY25 |
| Operating cash flow, year before | $47M |
| Operating cash flow | $543M |
| Capex, year before | $11M |

| Free cash flow | $516M |

| Of which: working capital released | 0.00 |
| Share of the increase that need not repeat | +0.0% |
| Operating cash flow before working capital: change | 807000000.00 |
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

A07 Stock compensation added back = no economic cost Not triggered confidence high
Stock compensation is 0.1% of revenue: small enough that adding it back changes little.

| Fiscal year | FY25 |
| Stock compensation | $21M |
| Revenue | $14.4B |
| SBC / revenue | +0.1% |
| Buybacks | 0 |

B02 Receivables growing = future cash is certain Not triggered confidence medium
Receivables grew 3% against revenue -2% in Q3 FY26; DSO 66 against a median of 64: collections are keeping pace with sales.
The figures and how they are read
| Quarter | Q3 FY26 |
| Revenue, year over year | -2.0% |
| Receivables, year over year | +3.1% |
| Quarter before | Q2 FY26 |
| Revenue y/y, quarter before | -0.4% |
| Receivables y/y, quarter before | -0.5% |
| Days sales outstanding | 65.8 |
| DSO, median of eight quarters | 64.0 |
| Receivables | $2.6B |
| Revenue | $3.5B |
receivables and revenue against the same quarter a year earlier; DSO = receivables / quarterly revenue × days, against the median of the eight quarters before

B08 Adjusted profit = economic profit Triggered severity high · confidence low
Adjusted EPS was at least 10% above GAAP in 3 of the last 3 quarters (on average 63% above). Costs excluded every quarter (restructuring, stock compensation, amortisation of acquired intangibles, litigation) are a recurring cost of the business, not a one-off.
The figures and how they are read
| Quarter / adjusted EPS / GAAP EPS / gap | 2025-12-31 / 0.54 / 0.18 / 0.667; 2026-03-31 / 0.61 / 0.22 / 0.639; 2026-06-30 / 0.67 / 0.27 / 0.597 |
| Quarters with adjusted ≥ 10% above GAAP | 3 |
| Quarters compared | 3 |
| Latest gap | +59.7% |
the analysts' 'actual' (usually the company's adjusted EPS) against GAAP net income ÷ diluted shares for the matching quarter; a gap of 10% or more counts (the stand-in until three releases' reconciliation tables are on file)
Source: 2025-12-31 (adjusted 0.54 vs GAAP 0.18) · 2026-03-31 (adjusted 0.61 vs GAAP 0.22) · 2026-06-30 (adjusted 0.67 vs GAAP 0.27)
What would explain it innocently
- A genuine one-off this year (an impairment, a settlement) that happens to span several quarters
- Amortisation of acquired intangibles, which many investors also exclude by choice
- The analysts' 'actual' is not the company's own adjusted figure
What to look for in the filing
- The reconciliation table in the earnings release: which items, how much, how often
- Whether the same items were excluded in earlier years
What would show the trap does not apply
- The reconciliation shows the excluded items ending (a restructuring with its final charge, a settlement paid) and the gap to GAAP closes in the next quarters
- The excluded items are only amortisation of acquired intangibles and the cash paid for the deals is in the investing cash flow
Look again: next filing.
C02 Low net debt = no refinancing risk Not triggered confidence medium

D03 EPS growth = profit growth Not triggered confidence high

E02 Low P/E at a cyclical peak = undervalued Insufficient data

E07 A precise DCF value = the true value To review confidence high
The DCF's point value is 27.49 a share (price 21.37); 62% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 2.47 to 52.52; across every method the research ran the range is 5 to 219. The value is a range; the decimals are not information.
The figures and how they are read
| dcf value | 27.49 |
| price | 21.37 |
| terminal value share | +62.1% |
| swing by input | Operating margin / ±3 pts / 2.47 / 52.52; Revenue growth (each year) / ±5 pts / 21.13 / 35.0; WACC / ±1 pt / 22.03 / 35.36; Capex (share of revenue) / ±1 pt / 24.52 / 30.47 |
| range all methods | 4.93; 218.54 |
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
Source: 2026-11-08 (valuation research)
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.

J08 A REIT's low net income = the dividend is unsafe Not applicable

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.
