The five investor questions
2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $264.0B to $403.4B, increasing; diluted EPS 7.23 to 38.38, increasing.
Median gross margin 5.0% over 10y, stable.
Median ROIC 28.9%, above the 12% hurdle in 57% of years.
Net debt/EBITDA 0.4x, interest coverage 25x.
Owner earnings -1.7%/yr, share count shrinking (buybacks).
Price vs. conservative owner-earnings floor
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- Owner earnings (normalized)
- $3.3B
- Owner-earnings floor / share
- $304.57
- Capped-growth comparison / share
- $304.57
- Recent price
- $840.90
- Price vs. owner-earnings floor
- 176% above owner-earnings floor
What today’s price assumes: owner earnings growing ~23%/yr over 5 years. The floor assumes owner earnings stay flat (0% growth).
How to read this
We solve for the constant annual change in owner earnings that would make the five-year floor equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.
This floor assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.
Cohort context: median current price is 239% above the floor across 48 of the current top 50 companies by Moat Score with both values.

20 years of fundamentals
The business, in plain English
McKESSON CORPORATION booked $403.4B of revenue in FY2026 in the Industrials sector and kept 3.6% of it as gross profit — a thin-margin business by that measure. After every other cost, 1.2% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $101.7B (FY2008) to $403.4B (FY2026) — about 8.0% a year compounded over 18 years.
It earned 1347.8% on invested capital in the latest filed year, FY2026. Across the full 16-year measurable filed record, median ROIC was 18.5%. Over the v3 recent window (7 measurable filed years), median ROIC was 28.9%. The Returns on Capital filter above scores it 85/100.
The balance sheet carried $6.5B of total debt in FY2026 against $4.8B of owner earnings — roughly 1.4 years of owner earnings to retire it all. Balance-Sheet Safety scores it 95/100.
Put together: Business Trend is the strongest of the five filters (95/100) and Pricing Power the weakest (16/100), which is how MCK lands at 68/100 — a Narrow moat.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Gaps in a line mean that item isn’t in MCK’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Track record
How McKESSON CORPORATION’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
How to read this: each dot is what the engine would have scored MCK on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the 1 year MCK rated Wide-moat (2017), the median forward total return that followed — measured only after each year’s filings were public — was:
- 1 year −28% vs the S&P 500’s −7% (price basis) · median over 1 year
- 3 years 13% vs the S&P 500’s 37% (price basis) · median over 1 year
- 5 years 147% vs the S&P 500’s 42% (price basis) · median over 1 year
These are medians computed from the data, not a claim about any one year. The company figures are total returns (dividends reinvested); the S&P 500 is the price-only ^GSPC index, which excludes dividends and so understates the index — the gap flatters the company. A quality rating is not a return forecast, and past returns don’t predict future ones. Educational only, not investment advice.

Common questions about MCK
- Does McKESSON CORPORATION have an economic moat?
- Based on its FY2026 SEC filings, the Moat Index scores McKESSON CORPORATION (MCK) 68.4 out of 100 — a Narrow moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 95, pricing power 16, returns on capital 85, balance-sheet safety 95, capital discipline 52.
- Is MCK trading below the conservative owner-earnings estimate?
- The conservative owner-earnings floor is $304.57 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $840.90, that is 176% above owner-earnings floor. The model also publishes a capped-growth comparison, but the floor is the cautious baseline. It assumes trailing owner earnings persist and is unreliable for declining businesses. This is an educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
- How has MCK's Moat Score changed over time?
- The record logs 16 readings since Jul 17, 2026; the latest reads 68.4 out of 100 (narrow moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
