MSFT — Q1 2026 Financial Report Analysis

Azure at 40% drove an 18% quarter — but a $4.1 billion OpenAI charge cut reported EPS growth to 13%

Microsoft's fiscal 2026 first quarter covers the three months to 30 September 2025 (Microsoft's financial year runs July to June, so this is its opening quarter, not a calendar-year one). The 10-Q was filed with the SEC on 29 October 2025.

Revenue was $77.7 billion, up 18% from $65.6 billion. Operating income — what is left of revenue after the cost of delivering products and services and all operating expenses, but before investment results and tax — rose 24% to $38.0 billion, faster than revenue, because operating expenses grew only 5% ($735 million) while revenue grew $12.1 billion.

Reported (GAAP) net income rose only 12%, and reported earnings per share 13%. The entire gap between the 24% operating-income growth and the 13% EPS growth sits below the operating line, in a single item: a $4.1 billion net loss on Microsoft's stake in OpenAI. Because Microsoft accounts for that stake under the equity method — meaning it books its share of OpenAI's profits or losses in its own income statement, whether or not any cash changes hands — OpenAI's spending flows straight into Microsoft's reported earnings. The filing quantifies the hit: $3.1 billion of net income and $0.41 of EPS this quarter, against $523 million and $0.07 a year ago. Excluding it, Microsoft's own "adjusted" EPS was $4.13, up 23%.

The numbers

Two Microsoft-specific gauges matter most here. Azure and other cloud services revenue growth is the company's consumption-based cloud and AI business — the closest thing it has to a single demand signal — and it grew 40%, with the filing attributing that to "demand for our portfolio of services with continued growth across all workloads." Commercial remaining performance obligation, or RPO, is contracted revenue Microsoft has sold but not yet recognised — in effect the order backlog. It reached $392 billion, up 51%, and about 40% of the total-company figure was expected to convert to revenue within twelve months.

Segments: everything grew, but for different reasons

Intelligent Cloud did the heavy lifting: server products and cloud services revenue rose $6.7 billion or 30%, essentially all Azure. But note the cost line — Intelligent Cloud's cost of revenue rose 43%, far ahead of its 28% revenue growth, "driven by growth in Azure," and the filing says segment gross margin percentage fell because of "the impact of scaling our AI infrastructure." Azure is still growing at 40%, but each incremental dollar of it is arriving at a lower margin than the dollar before.

Productivity and Business Processes grew 17% on Microsoft 365 Commercial cloud, where revenue per user rose on E5 and Microsoft 365 Copilot adoption while the paid-seat count grew only 6%. Growth here is increasingly about charging existing customers more, not adding new ones. Consumer subscriptions grew faster (Microsoft 365 Consumer cloud +26%) but from a much smaller base.

More Personal Computing's 4% growth is the line to read sceptically. Windows OEM revenue — licences sold to PC makers — grew 18%, but the filing is explicit about why: "demand ahead of Windows 10 end of support and inventory levels that remained elevated." That is demand pulled forward by a support deadline plus channel stock-building, not a recovering PC market. Meanwhile Xbox hardware revenue fell 29% on lower console volumes, and Xbox content and services grew just 1% "on a strong prior year comparable" — the year-ago quarter was unusually good, which flatters nothing this time.

What the headline numbers hide

• A currency tailwind in the profit lines. Gross margin and operating income each "included a favorable foreign currency impact of 2%" — that is, roughly two percentage points of the growth came from the dollar weakening against currencies Microsoft earns in, not from the business. Revenue, by contrast, was not materially affected.
• Sales and marketing spend was flat at $5,717 million — exactly unchanged year on year — while revenue grew 18%. Combined with R&D up only 8%, that is what produced the 2.3-point rise in operating margin. This is operating leverage from restraint in the commercial organisation, not from cloud economics; cloud gross margins moved the other way (Microsoft Cloud gross margin fell to 68%).
• Cash generation was strong but capital spending is compounding faster. Operating cash flow was $45.1 billion (+32%), capital spending $19.4 billion (+30%), leaving $25.7 billion after capex. Microsoft returned $11.8 billion via buybacks ($5.7bn) and dividends ($6.2bn).
• Legal costs, not growth, drove general and administrative expense up 8% to $1.8 billion.
• The tax rate was flat at 19%. New US tax law (the One Big Beautiful Bill Act, enacted 4 July 2025) helped, but was offset by where Microsoft earned its profits — the rate stays below the 21% US federal rate mainly because of its Irish regional operations centre.

Takeaway: Microsoft is now running two businesses with opposite margin trajectories inside one income statement. Azure revenue grew 40% while Intelligent Cloud's cost of revenue grew 43% and Microsoft Cloud gross margin slipped to 68% — growth is being bought with infrastructure. The 2.3-point rise in total operating margin came almost entirely from holding sales and marketing spend flat, which is a lever that can be pulled once. The OpenAI equity-method loss is the more volatile issue: at $4.1 billion it already exceeds a tenth of quarterly operating income, it is non-cash, and it will swing with OpenAI's results rather than Microsoft's.

What to watch next

Microsoft does not publish revenue guidance in its 10-Q (it gives that on the earnings call), so the forward signal in this filing is structural rather than numeric. Three things are worth carrying into the next quarter:

1. Management states the direction of margins plainly. The filing warns that "the investments we are making in cloud and AI infrastructure and devices will continue to increase our operating costs and may decrease our operating margins." That is a company-authored expectation, not an analyst's inference.
2. The $392 billion backlog is the real forward number. Growing 51% against 18% revenue growth, it says contracted demand is running far ahead of recognised revenue. Roughly 40% of the total-company figure was expected to land within a year.
3. The Windows comparison gets harder. Windows 10 support ended on 14 October 2025, two weeks into the following quarter. The 18% OEM growth and the "elevated" channel inventory both borrow from future quarters; expect that line to decelerate sharply once the deadline passes.

Our own read: the operating business is performing better than the reported EPS suggests, and the adjusted $4.13 is the fairer number for judging it. But the two sources of upside in this quarter — flat sales and marketing spend, and pulled-forward Windows demand — are both finite, while the cost pressure (AI infrastructure depreciation and the capital spending behind it) is only beginning to land in the income statement. The interesting question is not whether Azure keeps growing, but at what gross margin.
