Microsoft's capex outlook came down to $175 billion, and not because it plans to spend less

Microsoft now expects to spend about $175 billion on capital projects in calendar 2026. That is below the figure the company had been carrying, and it did not get there by planning to spend less. The spending plan stayed where it was. What changed is which accounting bucket the money lands in.

Why one quarter has two numbers

On the earnings call the company put capital expenditures for the April to June quarter at $41 billion. The cash flow statement for the same quarter shows $35.8 billion of additions to property and equipment. The two numbers part company over how leased facilities get counted.

Roughly two-thirds of the quarter's spending went to short lived assets, mainly server CPUs and GPUs. More money goes into the chips than into the shell that holds them.

Finance lease, operating lease

When a data center is rented rather than owned, the contract falls into one of two boxes. A contract that works like buying on installments is a finance lease. One that works like paying rent is an operating lease. Finance leases count as capital expenditure. Operating leases do not. Microsoft has extended the estimated useful life of its data centers and office buildings from 15 years to 25 years, effective with fiscal 2027. Once the asset is assumed to last 25 years, the same lease covers a smaller slice of that life, which pushes it toward the rent side. So future data center leases move into the operating lease box, and the reported capex number gets smaller. The chief financial officer said the greater impact is on capital expenditures.

Is profit being flattered

A longer life also means a smaller depreciation charge each year, which makes profit look bigger. The company said the change affects only the timing of future depreciation and should be a minimal benefit to fiscal 2027 operating income. The capex line moves more than the profit line does. The quarter itself was strong. Revenue was $90.0 billion, up 18%, and Azure passed $100 billion in annual revenue for the first time. The stock rose more than 8% after hours.

Meta went the other way that day

Meta lifted the floor of its 2026 capital spending range from $125 billion to $130 billion and left the ceiling at $145 billion. Second quarter revenue grew 28% to $60.8 billion, but operating margin fell from 43% to 31% and free cash flow came down to $784 million. Microsoft's free cash flow in the same quarter was $19.6 billion.

Meta reports mixed Q2 results, raises low end of capex guidance range, shares move lower (Benzinga, 2026-07-29)

Benzinga put Meta's adjusted earnings at $6.18 a share against a $7.13 estimate. Line the two companies up and the word capex turns out to count different things at each of them. Meta folds principal payments on finance leases into its capex figure. Microsoft's cash flow line leaves them out.

The stock rose 8%, so the market took the second reading. Either way, reported capex will now understate what is actually being spent.

What settles it

The question comes down to one thing. Can the reported capex line still stand in for how much is being spent on AI. If operating lease payments swell inside operating costs while capex stays flat, that line has stopped measuring the size of the spend. If both rise together, the reclassification did not matter much. For anyone selling memory or equipment, the hyperscaler capex line is the first place they look for demand. The rule that produces that number changed quietly this week, and that will outlast the earnings beat.
