Shares surged 9.2% to €423.05 after Microsoft delivered a fiscal Q4 earnings blowout that silenced — at least temporarily — months of investor anxiety over whether its enormous AI spending is actually generating returns. The stock had shed 19% year-to-date heading into the report , pummeled by fears that billions in data-center investment would burn cash faster than it created revenue. This quarter flipped that narrative.
An Earnings Beat That Went Beyond Expectations
Revenue hit $90 billion, up roughly 18% year-over-year, topping the $87.6 billion Wall Street consensus. Adjusted earnings per share of $4.74 cleared the $4.24 estimate by nearly 12%.
Part of the profit boost came from a $3.2 billion one-time gain on Microsoft's investment in AI lab Anthropic — but even excluding those items, the company said it exceeded expectations across revenue, operating income, and EPS. That distinction matters: it tells investors the core business is genuinely accelerating, not just flattering itself with paper gains.
Azure Crossed a Symbolic Threshold — And Growth Is Speeding Up
Azure cloud revenue grew 43% in Q4 — accelerating from 40% the prior quarter — and full-year Azure revenue surpassed $100 billion for the first time.
CFO Amy Hood guided first-quarter fiscal 2027 Azure growth to about 45% , signaling further acceleration. For shareholders, faster cloud growth directly justifies the massive infrastructure build because it proves enterprise customers are actually buying AI computing capacity, not just kicking tires.
A $678 Billion Backlog Suggests the Demand Is Real
Contracted-but-not-yet-recognized revenue — essentially signed deals waiting to be fulfilled — jumped 84% year-over-year to $678 billion, roughly twice Microsoft's entire annual revenue. That enormous backlog gives revenue visibility well into the future and undercuts the bear case that AI demand could evaporate.
The Cash Flow Question Hasn't Gone Away
Capital expenditures surged 70% to $41 billion in Q4 , and Microsoft expects roughly $175 billion in fiscal 2027 capital spending.
Free cash flow — the cash left after spending — fell 23% to $19.6 billion in the quarter.
Microsoft is also extending data-center building depreciation from 15 to 25 years, an accounting change that shrinks reported spending without reducing actual investment. Investors should watch whether AI revenue growth continues outpacing the spending needed to fuel it — because that math is the only thing separating a strategic investment from an expensive bet.
