Arm Holdings (ARM): analysis traps

Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q2 FY27, to Sep 30, 2026, filed Nov 4, 2026; rules v1.1

Arm Holdings (ARM): 2 rules of 10 triggered on the filings to Sep 30, 2026: stock compensation added back = no economic cost; FCF growth = the business improved. 2 to review; 2 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

Stock compensation added back = no economic cost Triggered · severity high · confidence high

Stock compensation was $1.1B, 21.4% of revenue, in FY26; buybacks were $0 (0.0× the SBC) and buybacks did not cover it. 'Adjusted' figures that add SBC back treat pay in shares as free; the cost is borne by every shareholder as dilution, or by the cash spent to buy the shares back.

Innocent reading: A young company paying in equity while it scales; intensity falls as revenue grows.

FCF growth = the business improved Triggered · severity medium · confidence medium

Free cash flow rose $801M (+450%), from $178M to $979M, but working capital released $868M more cash than the year before: more than the whole increase came from sources that need not repeat. Operating cash flow before working capital rose by $259M.

Innocent reading: An expansion programme finished, so capex fell back to maintenance levels for good.

Low P/E at a cyclical peak = undervalued To review · confidence medium

Net income of $936M is at a high against a median of $549M over eight years; at 199.5× the market is not pricing it as cheap, but a multiple on this year's profit still understates the mid-cycle one (340.2×).

B02 Receivables growing = future cash is certain Not triggered confidence medium

Receivables grew -3% against revenue 27% in Q2 FY27; DSO 70 against a median of 85: collections are keeping pace with sales.

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 triggered confidence high

EPS fell 46% and net income fell 45% in Q2 FY27; the share count rose 0.9%: EPS growth follows profit growth.

E02 Low P/E at a cyclical peak = undervalued To review confidence medium

Net income of $936M is at a high against a median of $549M over eight years; at 199.5× the market is not pricing it as cheap, but a multiple on this year's profit still understates the mid-cycle one (340.2×).

E07 A precise DCF value = the true value To review confidence high

The DCF's point value is 11.67 a share (price 173.25); 73% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from 9.96 to 13.39; across every method the research ran the range is 1 to 500. The value is a range; the decimals are not information.

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.
