Microsoft’s cloud business is growing quickly. Building the computing capacity behind that growth is expensive, too. The gap between those two facts is the question at the heart of the company’s latest earnings report.

For the quarter ended September 30, 2026, Microsoft reported revenue of $92.3 billion, up 19% from a year earlier. Azure revenue rose 48%, while Microsoft Cloud revenue reached $63.9 billion, up 30%, according to the company’s fiscal first-quarter results. The numbers show impressive demand for cloud services, but they don’t settle how much profit Microsoft will eventually earn on its infrastructure investment.

Microsoft trades on Nasdaq under the ticker MSFT. Its earnings figures below are in U.S. dollars and compare the latest quarter with the same period a year earlier, unless otherwise noted.

What Azure’s growth number actually means

Azure provides computing, storage, databases and other services that businesses can use without running all the hardware themselves. It also supplies infrastructure used for AI workloads. When Microsoft reports Azure revenue growth, it is describing a business measure, not the return on Microsoft stock.

The latest 48% year-over-year increase is a growth rate, not a dollar figure or a forecast. Microsoft’s broader Microsoft Cloud number includes Azure as well as Microsoft 365 commercial cloud and industry solutions cloud, so the cloud total should not be added to Azure as if they were independent businesses. The company explains its definitions in its investor metrics.

There’s a practical reason to care about that distinction. A fast-growing cloud platform can contribute to a much larger bundle of software and services, but each line comes with a different mix of customers, costs and growth rates. Knowing what is included helps investors avoid counting the same revenue twice.

A big backlog is not the same as cash in the bank

Microsoft said commercial remaining performance obligation, or RPO, rose 73% to $677 billion. RPO generally represents contracted future revenue that has not yet been recognized. It can give readers a sense of the scale of commitments, but it is not the same thing as revenue earned this quarter or cash collected today.

Timing matters. Revenue linked to long-term commitments can be recognized over multiple periods, while the cost of preparing infrastructure can arrive earlier. A larger backlog is useful context when evaluating demand, but it does not guarantee a particular margin, payment schedule or future share price.

Think of it this way: a restaurant might have reservations extending months into the future, but it still needs staff, equipment and ingredients to serve those meals. That comparison is only an illustration; Microsoft’s actual contracts and accounting are more complicated.

Why spending is part of the earnings story

On its October 28 earnings call, Microsoft said quarterly capital expenditures were $45.2 billion, including $7.4 billion in finance leases. It separately reported $39.4 billion in cash paid for property and equipment and $18.6 billion in free cash flow. The reported capital expenditure figure includes finance leases when they begin, so it should not be mistaken for cash paid in that quarter. Free cash flow is a useful complement to reported profit because it highlights cash left after spending on physical and other long-lived assets; definitions and timing still matter when comparing companies.

Chief Financial Officer Amy Hood said Microsoft expected capital expenditures of more than $50 billion in its fiscal second quarter. For calendar 2026, the company forecast approximately $170 billion in spending. Those are company expectations, not amounts already spent or a guarantee of future results.

Management also said some third-party capacity deliveries were delayed into the second half of the fiscal year. On the call, Hood pointed to spending on processors and graphics chips, including higher memory and storage costs, as part of the expected acceleration. A shift in when capacity arrives can alter quarterly spending without necessarily describing the long-term return on the investment.

For shareholders, the next question is whether future demand and pricing support enough revenue and cash flow to justify the infrastructure costs. Microsoft says improving efficiency gives each dollar of capital spending the potential to support more revenue and higher returns over time. That is management’s outlook, not a result investors can take for granted.

Two earnings figures tell different stories

Microsoft reported diluted earnings per share of $4.92 under generally accepted accounting principles, or GAAP, up 32% from a year earlier. Its non-GAAP figure, which excludes the impact of its OpenAI investments, was $4.89, up 18%.

The difference in growth rates is meaningful. Microsoft said its OpenAI investments added $207 million to net income in the latest quarter. In the comparable quarter a year earlier, investment losses reduced net income by about $3.1 billion. The swing helped the reported year-over-year comparison. It is a reason to read both measures, not proof that either one alone captures the full business.

Operating income, another view of the business, rose 21% to $45.9 billion. Readers comparing measures should keep the accounting definitions attached and remember that adjusted figures can exclude items that still have economic significance.

Not every Microsoft business moved in the same direction

The company’s results were not a single cloud chart. Microsoft 365 commercial cloud revenue increased 17% on a reported basis, while search and advertising revenue excluding traffic acquisition costs increased 12%. Windows OEM and Devices revenue fell 22%, and Xbox content and services revenue fell 2%, according to the earnings release.

Those differences matter because Microsoft sells into several markets at once. Cloud growth can be strong while device-related revenue declines. Neither figure alone explains the full company’s performance.

What to watch next

The useful follow-up is less about guessing tomorrow’s share price and more about checking whether growth, spending and cash generation continue to fit together. Watch future Azure and Microsoft Cloud growth, the timing and scale of capital expenditures, operating margins and free cash flow. Compare management’s forecasts with the results that eventually arrive, and check whether contract commitments become recognized revenue over time.

Microsoft has plenty of demand to discuss. Its next challenge is showing, over multiple quarters, what that demand earns after the bills for building the infrastructure come due. For another view of how costs can affect a major technology company, see our Apple earnings and margin analysis.
