Microsoft’s lower capex forecast reflects lease-accounting change, not reduced AI spending

Microsoft gave a capital-expenditure forecast below Wall Street estimates, but the headline reduction largely reflects a lease-accounting change rather than a pullback in its data-center and artificial-intelligence buildout.

The company expects approximately $50 billion of capital expenditure in its fiscal first quarter ending in September. That compares with a $56.02 billion analyst estimate cited by Reuters. Microsoft also adjusted its calendar 2026 capex expectation to approximately $175 billion from a previously stated $190 billion.

Chief Financial Officer Amy Hood said on Microsoft’s fiscal fourth-quarter earnings call that the company is extending the estimated useful lives of data centers and office buildings to 25 years from 15 years at the start of fiscal 2027. The change means more future data-center leases will be treated as operating leases instead of finance leases. Finance leases are included in Microsoft’s reported capital expenditures, while operating leases are not.

“Outside of this useful life impact, our calendar year 2026 CapEx investment expectations remain unchanged,” Hood said. The distinction matters for investors tracking demand across semiconductors, servers, networking equipment, power infrastructure and data-center construction: the lower reported capex figure does not indicate an equivalent reduction in physical capacity plans.

AI infrastructure spending remains elevated

Microsoft recorded $41 billion of capital expenditures in the June quarter, including higher component pricing. Roughly two-thirds went toward shorter-lived assets, primarily CPUs and GPUs, while the remainder funded longer-lived assets. Cash paid for property and equipment was $35.8 billion, and finance leases totaled $5.6 billion, primarily for large data-center sites.

The company said Azure customer demand continues to exceed available capacity. Azure and other cloud-services revenue increased 43% during the quarter, while Microsoft Cloud revenue reached $59.3 billion, up 27%. Commercial remaining performance obligations increased 84% to $678 billion, with all sequential growth attributed to customers outside frontier-model companies.

Microsoft’s earnings release also showed quarterly revenue of $90 billion and adjusted diluted earnings of $4.74 per share. Management said Azure surpassed $100 billion in annual revenue for the first time, while Microsoft 365 Copilot exceeded 30 million paid seats.

What matters next

For fiscal 2027, Microsoft expects capital expenditures to grow year over year because of demand across its portfolio. The next interpretation point will be whether quarterly cash spending, lease commitments and delivered cloud capacity continue expanding alongside Azure demand. Traders will also watch component costs, the mix between short- and long-lived infrastructure, and whether the accounting shift creates a widening difference between reported capex and Microsoft’s broader data-center obligations.
