McKesson (MCK): 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
McKesson (MCK): 1 rule of 10 triggered on the filings to Sep 30, 2026: FCF growth = the business improved. 2 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
FCF growth = the business improved Triggered · severity medium · confidence medium
Free cash flow rose $493M (+9%), from $5.2B to $5.7B, but capital expenditure fell by $423M: 86% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $633M.
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 $4.7B is at a high against a median of $3.0B over eight years; at 26.3× the market is not pricing it as cheap, but a multiple on this year's profit still understates the mid-cycle one (41.2×).
A precise DCF value = the true value To review · confidence high
The DCF's point value is 1,213.08 a share (price 1,060.84); 88% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from -1,528.03 to 3,699.27; across every method the research ran the range is -15,604 to 6,999. 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 Triggered severity medium · confidence medium
Free cash flow rose $493M (+9%), from $5.2B to $5.7B, but capital expenditure fell by $423M: 86% of the increase came from sources that need not repeat. Operating cash flow before working capital rose by $633M.
The figures and how they are read
| Fiscal year before | FY25 |
| Fiscal year | FY26 |
| Operating cash flow, year before | $6.1B |
| Operating cash flow | $6.2B |
| Capex, year before | $859M |
| Capex | $436M |
| Free cash flow, year before | $5.2B |
| Free cash flow | $5.7B |
| Change in FCF | $493M |
| Change in capex | −$423M |
| Working capital: change in its cash contribution | −$563M |
| Of which: capex cut | $423M |
| Of which: working capital released | 0.00 |
| Share of the increase that need not repeat | +85.8% |
| Operating cash flow before working capital: change | 633000000.00 |
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: FY26 (cash flow statement, fiscal year) · FY25 (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 0.1% of revenue: small enough that adding it back changes little.

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

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 Not triggered confidence medium

D03 EPS growth = profit growth Not triggered confidence high
EPS rose 17% and net income rose 10% in Q2 FY27; the share count fell 6.2%: EPS growth follows profit growth.

| Quarter | Q2 FY27 |

E02 Low P/E at a cyclical peak = undervalued To review confidence medium
Net income of $4.7B is at a high against a median of $3.0B over eight years; at 26.3× the market is not pricing it as cheap, but a multiple on this year's profit still understates the mid-cycle one (41.2×).
The figures and how they are read
| market value | $123.8B |
| net income ttm | $4.7B |
| pe ttm | 26.30 |
| net income median fy | $3.0B |
| pe mid cycle | 41.20 |

| down years in window | 2 |
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: Q2 FY27 (net income, trailing twelve months)
What would show the trap does not apply
- Profit holds at this level through the next two years (the eight-year peak was a new base, not a top)
- The industry's capacity and prices stay where they are rather than reverting

E07 A precise DCF value = the true value To review confidence high
The DCF's point value is 1,213.08 a share (price 1,060.84); 88% of it is the terminal value, a number about years no one has seen. Moving operating margin by ±3 pts alone takes it from -1,528.03 to 3,699.27; across every method the research ran the range is -15,604 to 6,999. The value is a range; the decimals are not information.
The figures and how they are read
| dcf value | 1,213.08 |
| price | 1,060.84 |
| terminal value share | +87.6% |
| swing by input | Operating margin / ±3 pts / -1528.03 / 3699.27; WACC / ±1 pt / 936.27 / 1699.14; Revenue growth (each year) / ±5 pts / 1031.94 / 1430.4; Capex (share of revenue) / ±1 pt / 1031.05 / 1395.11 |
| range all methods | -15604.4; 6998.74 |
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.

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.

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.
