Microsoft reported fiscal first quarter 2027 revenue of $92.3 billion, up 19% from a year earlier, for the quarter ended September 30, 2026. Net income rose 32% to $36.6 billion, diluted earnings came to $4.92 a share, and Azure, its cloud platform, grew 48%. The results beat Wall Street's revenue and earnings estimates.

The quarter tells the same story as the rest of big tech this autumn: the cloud and AI business is growing fast, and the cost of building it keeps rising. Microsoft is leaning into both at once, and the market spent the day after the report weighing one against the other.

Azure and the cloud did the heavy lifting

Azure revenue grew 48% in the quarter, the fastest pace Microsoft has reported for the platform in some time. Broader Microsoft Cloud revenue, which bundles Azure with the commercial parts of Office, Dynamics and other services, was $63.9 billion, up 30% from a year earlier. Chief financial officer Amy Hood said the company "delivered a strong start to the fiscal year with Microsoft Cloud revenue of $63.9 billion."

Operating income rose 21% to $45.9 billion, so the growth came with scale rather than at the expense of profit. Chief executive Satya Nadella framed the quarter around breadth, saying Microsoft is "delivering greater capability, choice, control, and cost efficiency for customers across our entire stack." The practical read is that Azure is where the AI demand is showing up in paid revenue, which is the test every cloud provider faces as it spends on capacity.

Cloud is not the whole company. Microsoft still earns heavily from its productivity and business tools, the commercial Office and Dynamics lines, and from the Windows and devices business, and those more mature lines help fund the cloud investment. But Azure is the part growing fastest and drawing the most attention, because it is the clearest gauge of whether enterprises are moving real workloads, and real budgets, onto AI infrastructure.

Capital spending keeps climbing

The spending side is the counterweight. Microsoft reported capital expenditures of about $45.2 billion for the quarter, and Hood indicated on the earnings call that the figure could exceed $50 billion in the December quarter. Part of the reason the quarter's number was not higher is that some third party data center capacity Microsoft had expected was delayed, pushing spending into later periods rather than removing it.

Microsoft also pointed to a large backlog as evidence the demand is there. Commercial remaining performance obligation, the contracted revenue it has not yet recognized, was reported at $677 billion, up 73% from a year earlier. A backlog that size is the company's answer to the question of whether the capacity it is paying for will be used.

The spending does show up in cash flow. Free cash flow for the quarter was reported at about $18.6 billion, down roughly 27% from a year earlier, as the capital outlays outpaced the growth in operating cash. That decline is the clearest sign of the trade Microsoft is making: it is converting a smaller share of its profit into free cash now in order to build capacity it expects to monetize later. Whether that trade looks wise depends entirely on how fast the AI revenue arrives.

The OpenAI line on the income statement

One wrinkle in the numbers is Microsoft's investment in OpenAI, the artificial intelligence lab it backs. GAAP net income of $36.6 billion and $4.92 a share included the impact of that stake, while Microsoft's non-GAAP figures, $36.4 billion and $4.89 a share, excluded it. The two measures were close this quarter, but the distinction matters because the OpenAI relationship is both a strategic asset and a line item that can swing reported profit.

For readers trying to separate the operating business from the accounting, this is a good example of why the GAAP and non-GAAP figures are both worth reading. Our explainer on the OpenAI IPO, now pushed to 2027 covers the wider context of how OpenAI's finances intersect with its largest backer.

How to read a quarter like this

The pattern across Microsoft's report is growth funded by heavy investment, with a backlog offered as proof the investment is warranted. Revenue up 19%, net income up 32% and Azure up 48% are the growth signals. Capital spending near $45 billion, heading above $50 billion, is the cost. The $677 billion backlog is the bridge between them. If you want a step by step on how these lines fit together, see our guide on how to read a company earnings report.

What to watch next

The questions for the next few quarters are specific. Can Azure hold growth near the high 40s in percentage terms as the comparisons get tougher. Does the capital spending actually clear $50 billion in the December quarter, and does free cash flow absorb it. And does the backlog keep expanding, because a backlog that stops growing would undercut the case for the spending.

Nothing here is a view on whether to buy or sell the stock, and Microsoft's own guidance is reported as the company's statement, not as a forecast from this desk. The takeaway is simpler: this was a strong operating quarter, and the market is now watching the spending line as closely as the revenue line. That balance, more than any single number, is what will define Microsoft's AI era.
