Microsoft reported fiscal fourth-quarter revenue of $90.01 billion against $87.62 billion expected, with adjusted earnings of $4.74 per share versus $4.24 expected. Azure and other cloud services grew 43%. The line that will be quoted for the next year: Azure now runs at more than $100 billion annually. Shares moved about 8% higher in extended trading.
The quarter
| Metric | Result | Expected |
|---|---|---|
| Revenue | $90.01B | $87.62B |
| Adjusted EPS | $4.74 | $4.24 |
| Azure & other cloud growth | +43% | — |
| Azure annual run rate | >$100B | — |
| Q1 FY27 revenue guidance | $89.85–90.95B | — |
| Implied growth at guide midpoint | +16% | — |
| Shares, extended trading | ~+8% | — |
A $2.4 billion revenue beat and a fifty-cent earnings beat on a company this size is not a rounding error. That is a beat driven by a business that was supposed to be decelerating and isn't.
What $100 billion actually means
Azure crossing a hundred billion dollars in annual revenue while still growing 43% is the part that deserves the attention, and not for the reason most headlines give.
Growth rates normally decay with scale — that is the single most reliable pattern in enterprise software. A business adding 43% on a $100 billion base is adding more absolute revenue per year than the entire revenue of most companies in the S&P 500. The fact that the deceleration hasn't happened yet is the strongest available evidence that AI workloads are genuinely additive demand rather than a reallocation of existing cloud budgets.
That distinction matters enormously. If AI spending were cannibalizing traditional cloud spend, you would see it here first — Azure would grow its AI line and shed elsewhere, and the aggregate would flatten. It hasn't.
The part I'd be careful about
The capital expenditure. This is the whole bear case and it should not be waved away.
Microsoft is spending at an unprecedented rate to build the capacity that produces this growth. Depreciation on that spending arrives on the income statement for years afterward, whether or not the demand persists at these rates. Every hyperscaler is making the same bet simultaneously, which means the industry is building supply against a demand curve nobody has actually seen the far end of.
The guide is the other thing worth reading carefully: $89.85 to $90.95 billion for the fiscal first quarter, which would be up about 16% at the midpoint. That is a fine number. It is also a meaningfully slower company-level growth rate than the Azure headline implies, which tells you how much of Microsoft is not Azure.
And there is a concentration point people ignore: a large share of the incremental AI cloud demand across the industry comes from a relatively small set of AI labs and AI-native companies, many funded by the same capital that funds their suppliers. That circularity is fine while it works and ugly if funding conditions change.
My take
This is the cleanest print in big tech this season, and I don't think that is controversial. Broad beat, accelerating flagship segment, credible guide.
My discipline on Microsoft has always been that you don't buy it for the quarter, you buy it for the fact that its revenue is the operating budget of every large enterprise on earth and that budget does not get cut quickly. The AI story is upside on top of that, not the reason to own it.
What I'd watch from here is the gap between capex growth and Azure growth. As long as revenue growth is running near or above the capex ramp, the bet is compounding. The quarter where capex accelerates and Azure decelerates is the quarter the entire AI infrastructure trade re-rates — and Microsoft is where you'd see it first, because it has the cleanest disclosure of the group.
Bottom line: Azure at $100 billion growing 43% is the strongest single data point that AI demand is additive. The capex is the bill for that, and it comes due in depreciation regardless.
