Key Takeaways
-
Microsoft lowered its calendar 2026 capex guide from about $190 billion to about $175 billion in July, but management said spending expectations are unchanged and the drop comes from how future data center leases are counted.
-
Capex jumped about 80% to $115.95 billion in fiscal 2026 while cash from operations rose about 34% to $182.94 billion, so calculated free cash flow slipped from $71.61 billion to $66.99 billion.
-
Microsoft’s NTM Market Cap / Free Cash Flow reads 116.92x against a 42.44x average, even though the stock is up only about 7% this year.
Microsoft’s $15 Billion Capex Cut Moved Spending Instead of Trimming It
On the Q4 2026 earnings call, Amy Hood spent a short stretch on what sounded like accounting housekeeping. Starting in fiscal 2027, Microsoft would stretch the estimated useful life of its data centers and office buildings from 15 years to 25.
The consequence arrived a few sentences later. More future data center leases will be treated as operating leases instead of finance leases, and Microsoft counts finance leases in capital expenditures but not operating leases. “Outside of this useful life impact, our calendar year 2026 CapEx investment expectations remain unchanged,” Hood said. The guide fell from about $190 billion in April to about $175 billion. The spending did not.
The cost has to land somewhere, and operating lease payments run through operating cash flow. Hood pointed to it herself when describing Q4, where cash from operations rose 30% to $55.4 billion, “partially offset by an increase in operating lease payments.” Free cash flow fell 23% to $19.6 billion.
The full-year pattern is starker. Capex went from $44.48 billion in fiscal 2024 to $115.95 billion in fiscal 2026, and its share of operating cash flow climbed from 38% to 63%. Calculated free cash flow fell from $74.07 billion to $66.99 billion over that stretch, even as operating cash flow rose from $118.55 billion to $182.94 billion. Depreciation and amortization, at $39.00 billion, has grown far more slowly than the spending behind it, and longer asset lives will stretch that gap further.
Management called the fiscal 2027 operating income benefit minimal. The bigger effect is on how capex reads.
Microsoft’s Free Cash Flow Multiple Now Carries the Bet
The market has noticed. TIKR’s NTM Market Cap / Free Cash Flow for Microsoft reads 116.92x, against a mean of 42.44x, a low of 23.16x and a high of 122.61x.
The stock did not double to get there. Reuters put it up roughly 7% year to date in late September, so the jump looks like the denominator shrinking, meaning forward free cash flow expectations falling. That is an inference, since the chart shows the multiple and not the estimates behind it.
