Microsofts Azure business generated $33.17 billion in fiscal 2027 first-quarter revenue, rising 48% from a year earlier on a constant-currency basis and exceeding the companys prior outlook. The disclosure, made for the first time in dollar terms, gives a clearer view of the cloud unit financing Microsofts expanding artificial intelligence infrastructure buildout.
Microsoft reported revenue of $92.3 billion for the quarter ended Sept. 30, up 19% from $77.7 billion a year earlier, according to its Oct. 28 earnings release. Operating income increased 21% to $45.9 billion, while GAAP net income rose 32% to $36.6 billion. Diluted earnings per share reached $4.92, also up 32%.
Azures performance was the standout in a quarter marked by surging demand for cloud computing capacity and a rapid expansion in data-center spending. The $33.17 billion result compared with $22.38 billion in the corresponding period a year earlier, an increase of roughly $10.8 billion.
Azure growth beats Microsofts forecast
Microsoft had previously forecast Azure constant-currency growth of 44% to 45% for the September quarter. The 48% result also surpassed the roughly 44% expectation cited in the supplied report.
The acceleration followed 43% constant-currency Azure growth in the preceding quarter. It suggests that demand for Microsofts cloud services has continued to rise even as the company works through constraints in bringing enough computing capacity online.
Microsoft Cloud revenue, which includes Azure and other enterprise cloud products, rose 30% to $63.9 billion, or 31% on a constant-currency basis. The companys newly structured Agents and Infra segment produced $76.8 billion in revenue, up 25%. That segment includes Azure, Microsoft 365 cloud services, productivity software and server licensing.
The revised reporting structure places AI services, cloud infrastructure and Microsofts core commercial software products in the same operating category. It also makes Azures contribution easier to measure as the company uses cloud capacity to support AI tools across its product range.
Contracted revenue points to a long delivery cycle
Commercial remaining performance obligations reached $677 billion, up 73% from a year earlier, Microsoft said. RPO measures contracted revenue that has yet to be recognized, making it a useful indicator of committed future enterprise spending.
Microsoft had previously stated that commercial RPO rose 25% excluding OpenAI. It also said the prior quarters sequential increase in RPO came entirely from customers outside frontier-model companies, indicating that demand for its cloud capacity extends beyond the largest AI developers.
The scale of unrecognized commercial commitments gives Microsoft a substantial revenue backlog, though it also places pressure on the company to build and deploy data-center capacity fast enough to meet contractual demand. For cloud customers, delivery timelines and access to high-performance computing have become as consequential as software pricing.
Capital spending remains elevated despite delivery delays
Microsofts capital expenditures plus finance lease additions totaled $45.2 billion in the quarter, up about 30% from $34.9 billion a year earlier. The result came in below managements previous expectation of more than $50 billion.
During the earnings call, Microsoft said delayed deliveries of third-party compute infrastructure reduced quarterly spending, while the companys broader infrastructure plans remained intact. It projected that second-quarter capital spending would exceed $50 billion.
The company now expects calendar-year 2026 capital spending of about $170 billion, compared with an earlier estimate of approximately $190 billion. Microsoft linked part of the change to both delivery timing and an accounting revision involving data-center leases.
Microsoft extended the estimated useful life of data centers and office buildings from 15 years to 25 years. The adjustment moves more future data-center leases from finance leases to operating leases, changing how those commitments appear in capital-expenditure measures without necessarily reducing the underlying infrastructure program.
Operating cash flow rose to $58 billion from $45.06 billion a year earlier. Free cash flow, calculated as operating cash flow less cash paid for property and equipment, was about $18.63 billion, down roughly 27% year over year. The decline reflects the cash demands of the companys physical expansion even as profits and operating cash generation climb.
OpenAI investment result lifts GAAP earnings
Microsofts GAAP net-income growth was also affected by a reversal in investment results tied to OpenAI. The company recorded a $207 million net gain related to those investments during the latest quarter, compared with an approximately $3.1 billion net loss a year earlier.
Excluding OpenAI-related investment gains and losses, Microsoft reported non-GAAP net income of $36.42 billion, up 18%, and adjusted diluted earnings per share of $4.89, up 18%. The adjusted EPS figure was above the approximately $4.73 analyst expectation cited in the supplied report.
The difference between the 32% GAAP net-income increase and the 18% adjusted increase shows how strongly the OpenAI investment swing influenced the headline result. Azures revenue growth and commercial backlog provide a more direct measure of Microsofts operating momentum.
Consumer hardware remains a drag
The Devices and Consumer segment reported revenue of $15.5 billion, down 3% year over year. Windows OEM and Devices revenue declined 22%, while Xbox content and services revenue fell 2%.
Search and news advertising revenue, excluding traffic acquisition costs, rose 12%, according to Microsoft. That growth did not offset the weakness in Windows OEM and device sales, leaving consumer hardware as a contrast to the companys stronger cloud and enterprise businesses.
Microsoft also said it offered a voluntary departure program to about 60,000 employees, or roughly 27% of the 223,000 employees it reported at the end of June. The program covers parts of teams in the United States, Canada, the United Kingdom and India, generally for roles at level 70 and below. Eligible employees were expected to decide by early December, with departures anticipated by year-end.
For the fiscal second quarter, Microsoft forecast revenue of $96 billion to $97.1 billion, representing growth of 18% to 19%. It expects Azure constant-currency revenue growth of 49% to 50%, while Agents and Infra revenue is forecast at $80.1 billion to $80.7 billion.
Microsoft also guided Microsoft Cloud gross margin to roughly 65%, reflecting a sales mix increasingly weighted toward Azure. The outlook captures the financial trade-off now shaping the company: cloud and AI demand are lifting revenue at an exceptional pace, while the data centers needed to serve that demand require one of the largest infrastructure spending programs in the technology sector.
