Microsoft reported on 28 October 2026 that Azure revenue grew 48% in the quarter to 30 September, its first quarter of fiscal 2027, according to the earnings release it filed with the SEC. Azure brought in $33.2 billion, against $22.4 billion a year earlier, the release’s product table shows.
The same filing shows what that growth is costing. Cash spent on property and equipment was $39.4 billion, against $19.4 billion a year earlier. Net cash from operations rose to $58.0 billion from $45.1 billion. By our arithmetic, free cash flow, cash from operations minus that spending, fell to $18.6 billion from $25.7 billion.

A vertical news Short narrated from the published headlines and opening lines of this piece and four related FourWeekMBA pieces on Microsoft.
Business Pill · CAPEX
An evergreen Business Engineer explainer on capital expenditure and depreciation. It explains the general idea only and is not about Microsoft’s results.
The key insight: As we read it, the filing shows two numbers moving in opposite directions: Azure revenue up 48% to $33.2 billion, and free cash flow, by our arithmetic, down 27% to $18.6 billion as cash capex doubled to $39.4 billion.
Update, 28 Oct: the filing and the earnings call.The earnings release puts commercial remaining performance obligation at $677 billion, up 73%. In July Microsoft reported $678 billion, up 84%, so by our arithmetic the backlog was roughly flat quarter on quarter while its year-on-year growth slowed (our backlog piece breaks it down).
Cash, cash equivalents and short-term investments fell to $64.5 billion on 30 September from $76.8 billion on 30 June. The cash flow statement shows $4.85 billion of debt repayments and lists no debt issuance in the quarter.
Operating lease right-of-use assets rose to $30.2 billion from $24.2 billion at 30 June, and operating lease liabilities to $21.7 billion from $16.5 billion.
Azure’s $33.2 billion was 35.9% of total revenue of $92.3 billion, and its $10.8 billion year-on-year increase was about 74% of Microsoft’s $14.6 billion revenue growth, both by our arithmetic from the release’s product table.
On the call.CNBC reported that Microsoft guided to $96 billion to $97.1 billion of revenue for the fiscal second quarter, which CNBC said works out to 18.8% growth at the midpoint, and that chief financial officer Amy Hood anticipates Azure growth of 49% to 50% in constant currency for the quarter, up from 48% in the first quarter. Hood also said on the call: “Some third-party capacity deliveries we expected in Q1 were delayed.” CNBC did not report a capex forecast. CNBC put capital expenditures including finance leases at $45.2 billion, up about 30% from a year earlier, and wrote that around 75% of capital expenditures are now tied to short-lived assets such as chips and GPUs, up from about 66% in the past three quarters and half a year earlier. Per CNBC, chief executive Satya Nadella said the number of people using Microsoft 365 Copilot is up 50% from last quarter, and Hood said the Microsoft 365 E7 bundle now has millions of seats.
Update, 28 Oct: the December-quarter guidance, from the call. A machine transcript of Microsoft’s earnings webcast (Microsoft’s official transcript was not yet available) has finance chief Amy Hood guiding to revenue of $96 billion to $97.1 billion, growth of 18% to 19%, with Agents and Infra at $80.1 billion to $80.7 billion, growth of 24% to 25%, and Devices and Consumer at $15.9 billion to $16.4 billion. She guided operating expenses of $18.5 billion to $18.6 billion, growth of 9%, and said the cost guidance across both COGS and operating expenses “includes an estimate for the recently announced employee voluntary exit offer.” Microsoft Cloud gross margin percentage “should be roughly 65%, down year over year,” and she put the Q2 effective tax rate at approximately 20%.
On funding, Hood said Microsoft expects to remain free-cash-flow positive in fiscal 2027 and that “we will access additional sources of funding when we believe it is attractive to do so.” Asked later how Microsoft would raise capital, she said: “There’s a form of financing called leasing, and we’ve been using that one as a vehicle.”
Operating income: $45.9 billion, up 21% (22% in constant currency).
Net income: $36.6 billion, up 32% on a GAAP basis; $36.4 billion, up 18%, on a non-GAAP basis that excludes the impact of Microsoft’s investments in OpenAI.
Earnings per share: $4.92, up 32% (GAAP); $4.89, up 18% (non-GAAP).
Microsoft Cloud: $63.9 billion, up 30% (31% in constant currency).
Commercial remaining performance obligation: up 73% to $677 billion. This is contracted revenue not yet recognised, Microsoft’s backlog.
Shareholder returns: $10.2 billion in dividends and share repurchases.
Microsoft, quarter to 30 September, 2025 vs 2026: additions to property and equipment $19.4B to $39.4B; Azure revenue $22.4B to $33.2B; net cash from operations $45.1B to $58.0B; free cash flow (our arithmetic: cash from operations minus additions to property and equipment) $25.7B to $18.6B.

What Nadella and Hood Said
Chief executive Satya Nadella said in the release: “We are delivering greater capability, choice, control, and cost efficiency for customers across our entire stack.” He added: “By helping organizations build and own their own intelligence, and earning trust through agent safety and security, we are translating our innovation into growing adoption and real-world impact across every industry.”
Chief financial officer Amy Hood said: “We delivered a strong start to the fiscal year with Microsoft Cloud revenue of $63.9 billion, with growth accelerating to 30% (up 31% in constant currency) year-over-year.” She added: “Results exceeded expectations across revenue, operating income, and earnings per share.”
Capex Doubled, Cash Flow Did Not Keep Up
Additions to property and equipment, the cash Microsoft spent on data centres, servers and other equipment, were $39.367 billion in the quarter, against $19.394 billion a year earlier. That is about 2.03 times the year-ago figure, by our arithmetic.
Net cash from operations grew 29%, from $45.057 billion to $58.000 billion, by our arithmetic. Because spending grew faster than cash coming in, free cash flow by our calculation fell 27%, to $18.633 billion from $25.663 billion.
The release’s cash flow statement does not give a capital expenditure figure that includes finance leases. Microsoft’s balance sheet shows net property and equipment of $346.8 billion at 30 September, against $313.1 billion at 30 June.
Where the Growth Came From
Microsoft now reports two segments, after the changes it announced in September 2026, and has recast prior periods to match. Agents and Infra revenue was $76.8 billion, up 25%, with operating income of $40.6 billion. Devices and Consumer revenue was $15.5 billion, down 3%, with operating income of $5.4 billion.
Microsoft 365 commercial cloud revenue rose 18% on an adjusted basis (17% as reported).
Search and advertising revenue excluding traffic acquisition costs rose 12%.
Xbox content and services revenue fell 2%.
Windows OEM and devices revenue fell 22%, to $3.6 billion from $4.6 billion.
The OpenAI Line
Microsoft’s GAAP results include the impact of its investments in OpenAI, which its non-GAAP figures exclude. The release’s reconciliation table shows that impact added $0.03 to GAAP earnings per share in the quarter, after cutting $0.41 a year earlier. That swing is why GAAP net income grew 32% while non-GAAP net income grew 18%.
Guidance Comes on the Call
The release says Microsoft “will provide forward-looking guidance in connection with this quarterly earnings announcement on its earnings conference call and webcast”, scheduled for 5:30pm Eastern (21:30 UTC) on 28 October. In July, as we reported in our fourth-quarter piece, Microsoft guided fiscal 2027 capital expenditure to about $255–260 billion. This piece will be updated with what Microsoft says on the call.
The Structural Read
As we read it, the backlog is the other side of the spending: Microsoft reported commercial remaining performance obligation of $677 billion, up 73%, which is contracted revenue it has not yet recognised.
Net cash from operations grew 29% by our arithmetic, to $58.0 billion; additions to property and equipment grew about 103%, which is why free cash flow fell even as revenue rose 19%.
The release leaves the fiscal 2027 capex outlook to the call; in July Microsoft guided to about $255–260 billion, as our fourth-quarter piece reported.

“Results exceeded expectations across revenue, operating income, and earnings per share.”
Three Implications
FOR MICROSOFT The release shows cash capex of $39.4 billion in one quarter against $58.0 billion of cash from operations.
FOR INVESTORS Free cash flow, by our arithmetic, was $18.6 billion against $25.7 billion a year earlier; guidance comes on the 5:30pm Eastern call.
FOR CUSTOMERS Nadella said Microsoft is delivering “greater capability, choice, control, and cost efficiency for customers across our entire stack.”
The Business Engineer Lens
This story maps onto the Business Engineer framework The AI Capex Map.
The framework argues that “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative,” naming OpenAI and Anthropic.
Microsoft’s release reports a $677 billion commercial backlog but does not say how much of it comes from any one customer. The framework was published in May 2026, before these results.
The release does not say how much of the quarter’s spending went to AI chips versus buildings and land, what Azure revenue came from AI services, or whether the fiscal 2027 capital expenditure guide has changed. Those may come on the call; we have not yet heard it.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Microsoft reported Azure revenue up 48% to $33.2 billion and a commercial backlog of $677 billion. Its cash spending on property and equipment doubled to $39.4 billion, and free cash flow, by our arithmetic, fell to $18.6 billion from $25.7 billion a year earlier.
