Shares surged after Microsoft delivered a fiscal Q4 earnings beat that silenced — at least temporarily — the debate over whether the industry's massive AI infrastructure buildout is producing real returns. Adjusted EPS of $4.74 crushed the $4.24 consensus by nearly 12%, while revenue of $90.0 billion topped the $87.6 billion estimate, growing 18% year over year.
Azure Crossed $100 Billion and Is Still Accelerating
Azure surpassed $100 billion in annual revenue for the first time, rising 41% over last year's $75 billion.
Q4 Azure growth hit 43%, with management expecting continued acceleration into the first half of fiscal 2027.
CFO Amy Hood guided Q1 Azure growth to roughly 45% in constant currency — a rare case of a $100-billion-scale business getting faster, not slower. For shareholders, that trajectory is the single most important variable supporting the stock's premium valuation.
The Earnings Beat Was Fatter Than It Looks — and Thinner
Results included a $3.2 billion gain from Microsoft's stake in Anthropic, adding 33 cents per share.
Even stripping out a 27-cent benefit from one-time items, the company said it beat expectations on revenue, operating income, and EPS. Meanwhile, the More Personal Computing segment fell 4% to $12.9 billion, with Windows OEM revenue down 7% and Xbox down 10% — a reminder that not every business inside Microsoft is riding the AI wave.
Record Spending Is the Price of Admission
Capital spending hit a record $41 billion in the quarter and free cash flow fell 23% as Microsoft races to add data-center capacity. The company expects roughly $175 billion in fiscal 2027 capital expenditure , and Q1 alone will top $50 billion. That's real money even for a company generating $183 billion in annual operating cash flow. Investors are currently willing to fund this buildout because Azure's growth is visibly accelerating, but the margin for error narrows with every dollar spent.
Copilot's 30 Million Seats Test the Next Growth Thesis
Microsoft 365 Copilot — the company's AI assistant embedded in Office apps — surpassed 30 million paid seats, with net additions more than doubling quarter over quarter.
Microsoft is also rolling out usage-based billing alongside per-seat licensing , a shift designed to widen the customer funnel. Whether Copilot can evolve from a fast-growing add-on into a significant revenue driver will shape how much further the stock can climb from here.
