Microsoft reveals Azure revenue for the first time

Microsoft put a dollar figure on Azure for the first time, in an 8-K filed on 2 September 2026 with an investor presentation attached as Exhibit 99.1, "FY27 Segments and Investor Metrics." The document was furnished under Regulation FD, and every number below comes from it.

Be precise about what this is. It is a segment reporting and metric definition change that takes effect with fiscal 2027. It is not an earnings release, not a revenue beat or miss, not a guidance raise, and not a reorganization of the business itself. Microsoft says total company revenue, cost of revenue and operating expense outlooks are all unchanged. The company did not change how much money it makes. It changed how it shows it.

The number Microsoft never gave before

Restated Azure revenue was $101,938 million for fiscal 2026, against $72,610 million for fiscal 2025. Fiscal 2026 fourth-quarter Azure revenue was $29,417 million. Restated total company revenue for fiscal 2026 was $331,839 million, unchanged from as reported.

Until now, Microsoft disclosed Azure only as a growth percentage, folded inside "Server products and cloud services," a line that was $129,425 million in fiscal 2026 with no Azure dollar figure inside it. Investors modeling the single most important asset in the AI infrastructure buildout were doing it off a percentage. Now there is a line.

Two segments where there were three

Beginning with fiscal 2027, Microsoft moves from three reportable segments to two. Out go Productivity and Business Processes, Intelligent Cloud, and More Personal Computing. In come "Agents and Infra" and "Devices and Consumer."

The plumbing underneath moves too. Azure's definition narrows: GitHub cloud and other developer cloud services move out of Azure into Microsoft 365 commercial cloud, Security Copilot moves out into Microsoft 365 commercial cloud, and Healthcare and Life Sciences cloud moves into a newly created Industry solutions cloud metric. That new Industry solutions cloud is built from Dynamics 365, LinkedIn Talent Solutions, LinkedIn Sales Solutions, and Healthcare and Life Sciences cloud, and LinkedIn stops being a standalone line. Search and advertising absorbs LinkedIn Marketing Solutions and LinkedIn Premium Subscriptions. Microsoft 365 commercial seat growth now counts paid GitHub seats.

CEO Satya Nadella framed it as "updating our financial reporting to mirror how the business is operating, how we allocate resources, and where we are headed," giving investors "full transparency of quarterly revenue across each of our key businesses, including Azure, M365 Cloud, Industry solutions, and ads." He added that AI "is blurring the boundaries between our products and reshaping our business models."

The part almost nobody did the arithmetic on

Here is what the reclassification does that the headlines skipped. Stripping GitHub cloud, Security Copilot and Healthcare cloud out of Azure makes Azure grow slightly slower on paper:

• Fiscal 2026 full year: 41% as previously reported for "Azure and other cloud services," against 40% for Azure as restated.
• Fiscal 2026 fourth quarter: 43% as reported, against 42% restated.
• Fiscal 2027 first-quarter outlook: "approximately 45%" in constant currency, given on 29 July 2026, mechanically adjusted to 44% to 45% in constant currency for the narrower Azure.

So roughly a point of growth comes off Azure and lands in Microsoft 365 commercial cloud, whose restated fiscal 2026 growth rises to 18% from 17% as reported. Anyone comparing next quarter's Azure number to their old model is comparing two different Azures. The rest of the fiscal 2027 first-quarter adjusted outlook: Agents and Infra revenue of $75.15 to $75.75 billion, Devices and Consumer of $14.7 to $15.2 billion, total company unchanged.

More transparency and less, in the same filing

The honest reading holds both sides. At the product level this is more transparency, and Microsoft and the wires both framed it that way. Investors get an Azure dollar line they never had. But the same filing cuts reportable segments from three to two, which is less segment-level detail, not more. Both things are true in the same document. The Information called it an accounting overhaul, while CNBC and Reuters called it a reporting shift, and the filing supports either label depending on which half you read.

None of this changes the demand story that sits underneath, the same one straining balance sheets from Nvidia's data-center guidance to the Azure tenants now worrying about data theft. It changes the yardstick you measure it with.

The takeaway

Before Microsoft's fiscal 2027 first-quarter print, rebase your Azure model onto the restated $101.938 billion and the narrower definition, and move GitHub cloud and Security Copilot into the Microsoft 365 line where they now live. Do it before the print, not after, so the first Azure number under the new structure is not misread as a slowdown when it is really a reclassification. The growth rate did not fall. The perimeter moved.
