Microsoft scores 79 out of 100 on Investily's report card. That is a good score, and it is also a long way below where the company's profit engine alone would put it. The reason sits in one line of the cash flow statement, and it is the most important number in the business right now.
The score: 79/100
Microsoft grades well almost everywhere. Revenue is compounding, the margin is enormous and stable, the balance sheet is conservative, and returns on capital are strong. What holds the score back is not a weakness in the business — it is that one growth component has turned negative while the valuation still assumes everything is compounding at once.
Growth: operating income is outrunning revenue
Revenue grew 17.9% over the trailing year, and it has been remarkably consistent — 16.2% over three years and 15.0% over five. Very few companies this size hold a growth rate that steady for that long.
Operating income grew faster still, at 20.9%. When operating profit outpaces revenue, the business is getting more profitable as it scales rather than merely larger. On the income statement, this is close to a perfect picture.
The line that costs Microsoft points
Free cash flow fell 6.3% over the trailing year, and it has grown only 4.1% a year over three. Set that against 17.9% revenue growth and 20.9% operating income growth and the gap is glaring: profit is compounding at nearly 21% a year while the cash actually left over is going backwards.
This is not an accounting problem. It is a capital spending decision. Microsoft is converting cash into AI datacenter capacity, and you can see it in the balance sheet as clearly as in the cash flow statement — book value grew 28.9% over the trailing year against revenue growth of 17.9%. The capital base is expanding faster than the business it supports.
Returns and the balance sheet
Return on capital employed sits at 26.9%, essentially unchanged from its three-year (28.8%) and five-year (28.5%) levels. That stability matters. It means the capital going into datacenters has not yet dented what Microsoft earns on the money already invested. The cash-flow version of that measure tells the other half of the story at 15.0%, well below the accounting figure — the gap is the spending.
- Net margin: 36.1%, flat against its 36.4% five-year level
- Debt to equity: 0.3 — funded from cash flow, not borrowing
- Current ratio: 1.4, comfortable rather than fortress-like
Valuation
Microsoft trades in the high-20s on trailing earnings, and a shade under that on next year's consensus. Against 17.9% revenue growth and a 36% margin that is not obviously expensive — the PEG sits just under 0.9. But price it against cash rather than profit and it looks very different: the market pays roughly 56 times free cash flow. Which multiple is the honest one depends entirely on whether you believe the capex is temporary.
The bottom line
Microsoft's 79 is a score with one clear question inside it. The operating business is compounding at 20%+ with a stable 27% return on capital and almost no debt. The cash that business throws off is shrinking, because it is being spent on capacity for a demand curve nobody can yet measure.
If that spending earns its keep, today's 56x free cash flow is a temporary distortion and the score understates the company. If it does not, Microsoft has spent several years of cash flow building depreciation. This is exactly the situation described in free cash flow vs net income — the two numbers disagree, and the disagreement is the story.
