Microsoft’s $15bn capex ‘cut’ explained: leases, not less AI

Last checked 2026-10-26

Short answer

Microsoft's calendar-2026 capital-spending guidance went from about $190 billion in April to about $175 billion in July, but CFO Amy Hood said investment expectations were 'unchanged'. The gap is classification: Microsoft extended datacentre useful lives from 15 to 25 years, so more leases count as operating leases, which sit outside capex. Wednesday's results on 28 October are the first full quarter under the new rule.

• What happened On 29 July Microsoft said calendar-2026 capex expectations were 'approximately $175 billion', down from the roughly $190 billion given in April, with the difference explained by a lease-accounting shift.
• Why it matters Finance leases are counted in Microsoft's capex figure; operating leases are not. Longer assumed asset lives push the same datacentre lease from one bucket to the other, so headline capex understates the build.
• What the quarter should show Microsoft guided capex of over $50 billion for the July to September quarter and said fiscal 2027 capex would grow year over year.
• What to watch Three lines on 28 October: total capex including finance leases, the finance-lease component ($5.6 billion in the June quarter) and lease commitments not yet commenced ($329.1 billion at 30 June).

$15 billion: the number that moved, and the one that did not

Fifteen billion dollars is the gap between two guidance figures Microsoft gave three months apart. On 29 April 2026, alongside fiscal third-quarter results, the company told investors to expect about $190 billion of capital spending in calendar 2026, a figure CNBC reported as driven partly by soaring memory prices. On 29 July, at fiscal fourth-quarter results, CFO Amy Hood put the same expectation at 'approximately $175 billion'.

Read quickly, that looks like a retreat. Read slowly, it is not. Hood's words on the call were that 'outside of this useful life impact, our calendar year 2026 CapEx investment expectations remain unchanged', and that 'the shift from finance to operating leases' adjusts the reported expectation to about $175 billion. CFO Dive summarised the same point: the lower number reflected an accounting change, not fewer servers. Microsoft added 31 datacentres in the June quarter, according to that report.

One distinction matters here. The $15 billion is a difference between two forward expectations. It is not a reported reclassification of money already spent, and nothing was 'moved' in cash terms. Equally, this is not sleight of hand. A change in estimated useful life is a disclosed change in accounting estimate under US GAAP. Hood said it affects only the timing of future depreciation, with a minimal benefit to fiscal 2027 operating income.

What is a finance lease, and why does it count as capex?

Microsoft's 'capital expenditures', as discussed on earnings calls, is cash spent on property and equipment plus assets acquired under finance leases. That is why the June quarter shows two different numbers for the same thing: $41 billion on the call, but $35.8 billion on the press-release cash-flow line. Finance leases, mostly for large datacentre sites, make up the $5.6 billion between them. Microsoft's press release on its investor-relations site does not break finance leases out separately.

A lease is a finance lease under the US standard, ASC 842, if it meets any of five tests. One test asks whether the lease term covers a 'major part' of the asset's economic life. The standard dropped the old 75% bright line, but, as the FinQuery explainer notes, it says continuing to use 75% as the threshold is reasonable. A finance lease is treated much like buying the asset with debt: the building goes on the balance sheet as a capex addition, and the principal repayments sit in financing cash flows. An operating lease is treated more like rent: payments run through operating cash flow, and nothing shows up in capex.

Now apply the useful-life change. A 15-year datacentre lease is 100% of a 15-year assumed life, well over any 'major part' test. The same 15-year lease is 60% of a 25-year life, below the customary 75% line. Nothing about the building, the lease or the rent changed. Only the classification did. As Hood put it, 'more of our future data center leases will shift from finance leases to operating leases', and 'finance leases are included in capital expenditures while operating leases are not'.

• Finance lease: asset counted in capex; principal repayments in financing cash flows (Deloitte, ASC 842-20-45-5).
• Operating lease: nothing in capex; payments in operating cash flows, so they weigh on operating and free cash flow over time rather than on the capex line.
• The cost does not disappear. As TIKR's explainer puts it, the shift moves the cost rather than eliminating it.

Is Microsoft spending more or less on AI than it was in April?

By every underlying measure, more. Quarterly capex went from $31.9 billion in the January to March quarter, as reported by CIO Dive (which may show cash additions only), to $41 billion including finance leases in April to June. Guidance for the July to September quarter now being reported is 'over $50 billion'. Hood also said fiscal 2027 capital expenditures would grow year over year. Roughly two-thirds of the June quarter's $41 billion went to short-lived assets such as CPUs and GPUs, which is the spend most directly tied to AI capacity.

The fiscal-year frame tells the same story. Cash additions to property and equipment reached $115.9 billion in fiscal 2026, the year ended 30 June. TIKR's figures put operating cash flow at $182.94 billion and free cash flow at $66.99 billion, down from $71.61 billion a year earlier. Revenue for the June quarter was $90.0 billion, up 18%, and Azure and other cloud services grew 43%, according to Microsoft's press release.

Two frames need separating. The $175 billion is a calendar-2026 number and straddles two fiscal years: the second half of fiscal 2026 and the first half of fiscal 2027. By contrast, the $115.9 billion is fiscal 2026 cash PP&E only, with no finance leases in it. Wednesday's quarter is the third of the four calendar-2026 quarters, so by Wednesday evening readers will have three of the four pieces of the $175 billion, though not all on a like-for-like definition.

How does Microsoft compare with Alphabet, Amazon and Meta?

Microsoft is the only one of the four whose 2026 number went down between April and July, and it attributed the drop to accounting. Alphabet and Amazon raised theirs on demand and cost grounds; Meta narrowed its range. Alphabet raised its full-year 2026 range on 22 July to $195 billion to $205 billion from $180 billion to $190 billion, citing faster delivery of capacity; its second-quarter purchases of property and equipment were $44.924 billion.

Amazon's Andy Jassy said on 30 July the company now expects about $220 billion, up from $200 billion, owing to higher memory costs, and still would not have enough capacity to meet 2026 demand. Meta reported second-quarter capex of $31.08 billion and narrowed its range to $130 billion to $145 billion from $125 billion to $145 billion.

A caution on adding these up. Reuters' 'Wall Street Week Ahead' on 26 October put hyperscaler capital spending at around $800 billion this year. That aggregate mixes definitions. Meta's figure explicitly includes principal payments on finance leases. Alphabet reports cash purchases of property and equipment. Amazon includes finance leases on its own definition. Microsoft includes finance leases, but from 1 July fewer leases qualify. The totals are useful as a scale marker, not as a league table.

Company	Earlier 2026 guidance	July 2026 guidance	Direction and stated reason
Microsoft (calendar 2026)	~$190bn (April)	~$175bn	Lower; lease classification after useful-life change
Alphabet	$180–190bn	$195–205bn	Higher; faster capacity delivery
Amazon	~$200bn	~$220bn	Higher; higher memory costs
Meta	$125–145bn	$130–145bn	Narrowed; no single reason given. Figure includes finance-lease principal.

What should readers look for on 28 October?

Microsoft publishes fiscal 2027 first-quarter results after the US market close on Wednesday 28 October 2026, with the webcast at 2:30 p.m. Pacific Time, according to the company's own earnings-date notice. Alphabet reports the same afternoon, with its call at 1:30 p.m. PT, and the Federal Reserve announces its policy decision the same day. Amazon follows on Thursday 29 October at 2:00 p.m. PT.

Three lines matter more than the headline. First, capex including finance leases, the figure Hood will give on the call, against guidance of 'over $50 billion'. Second, the finance-lease component itself. It was $5.6 billion in the June quarter, and this is the first full quarter under the 25-year assumption. A smaller number here would be the mechanism working as described rather than a change in building plans.

Third, the leases note. Microsoft's fiscal 2026 Form 10-K, filed with the SEC on 29 July 2026, reported $329.1 billion of leases, primarily for datacentres, that had not yet commenced at 30 June 2026, according to BTW Media's reading of the filing. They start between fiscal 2027 and fiscal 2033, with terms of one to 20 years. That line, and operating-lease payments running through operating cash flow, is where the spending that no longer counts as capex will appear.

A rough rule for Wednesday: if capex comes in above $50 billion and the finance-lease slice shrinks, both things Microsoft has already described, the build grew while the accounting narrowed what the capex line captures. The press release will not settle it, because it shows cash PP&E and not finance leases. The call should give the finance-lease split; the 10-Q leases note is where the operating-lease payments and uncommenced commitments would appear, though Microsoft has not said how much of that it will disclose on 28 October.

• Capex including finance leases (guided 'over $50 billion').
• Finance leases within that figure ($5.6 billion in the June quarter).
• Operating-lease payments and lease commitments not yet commenced ($329.1 billion at 30 June 2026).

What is not confirmed

The primary documents are Microsoft's own fourth-quarter press release, published on its investor-relations site, and the fiscal 2026 Form 10-K, filed with the SEC on 29 July 2026 (accession 0001193125-26-323660). Useful-life and lease figures come from the earnings-call transcript and from outlets citing the 10-K, and should be checked against the filing itself on SEC EDGAR. Microsoft has not confirmed a fiscal 2026 full-year capex figure including finance leases; CIO Dive's $31.9 billion third-quarter figure may be cash PP&E only. Its roughly $25 billion of component pricing inside April's $190 billion is a paraphrase, not a verbatim quote.

Revenue and Azure guidance for the quarter being reported circulated in previews but are not confirmed from the transcript, so they are left out here. Reuters' own 'Wall Street Week Ahead' article could not be retrieved and is cited via Business Recorder's syndication. Whether Microsoft will disclose operating-lease payments or uncommenced-lease totals in the first-quarter 10-Q on 28 October, or in a later filing, is also not confirmed. No results are out as of 26 October; every first-quarter figure above is guidance.
