Microsoft just shaved roughly $15 billion off its calendar year 2026 capital expenditure forecast. The number dropped from around $190 billion to approximately $175 billion, which sounds like a company tapping the brakes on spending. It’s not.

The revision, disclosed during the fiscal Q4 2026 earnings call on July 29, stems from an accounting change that reclassifies how certain data center leases are categorized. The company’s actual spending plans haven’t budged. Investors apparently got the memo: shares climbed more than 8% in after-hours trading.

What the accounting change actually does

Starting at the beginning of fiscal year 2027, Microsoft is extending the estimated useful life of its data centers and office buildings from 15 years to 25 years. That single adjustment changes how leases get classified under accounting rules.

With a longer useful life assumption, more of Microsoft’s data center leases shift from “finance leases” to “operating leases.” Finance leases show up on the balance sheet as capital expenditures. Operating leases hit the income statement as operating expenses instead. Same money going out the door, different line item on the financial statements.
