Microsoft's Azure Grows 48%, but AI Spending Is Set to Climb Further
Revenue and earnings beat expectations. Investors now need to see when AI revenue growth turns into better cash flow.
The number the market liked most was Azure's 48%, not EPS
Microsoft's fiscal first-quarter 2027 revenue (July to September 2026) was $92.28 billion, up 19% from a year earlier. Adjusted earnings per share were $4.89, above the $4.73 analysts expected.
The most important figure in the report, though, is Azure's 48% growth.
That beat the company's own guidance of 44% to 45%. It also came on quarterly Azure revenue of $33.17 billion, a large base to grow from at that pace.
The source of the growth is more interesting. CFO Amy Hood said it came not only from growth in Foundry, Microsoft's AI development platform, but also from better GPU operating efficiency and from monetizing idle CPU capacity.
Building new data centers is not the only way to grow. The ability to generate more revenue from servers already installed is becoming important too. Over time, that suggests capital efficiency could improve.
Microsoft's results in numbers
- +48%: Azure revenue growth, year over year
- 49% to 50%: next-quarter Azure growth guidance, constant currency
- 49.8%: operating margin for the quarter
- -27%: change in free cash flow, year over year
| Metric | This quarter | What it means |
|---|---|---|
| Revenue | $92.28 billion | +19% year over year |
| Adjusted EPS | $4.89 | Above the $4.73 consensus |
| Azure revenue | $33.17 billion | +48% year over year |
| Microsoft Cloud | $63.9 billion | +30% year over year |
| Operating income | $45.92 billion | Operating margin of about 49.8% |
| Free cash flow | $18.63 billion | About -27% year over year |
| Capex, including finance leases | $45.2 billion | Below expectations, but still a high level |
Revenue, operating income and cloud growth rates are based on company disclosures. Market expectations and investment metrics also draw on financial data.
Why lower-than-expected spending is not much comfort
Capital expenditure including finance leases came to $45.2 billion this quarter, below the $50.67 billion analysts expected.
Hood said, however, that delivery of some external computing capacity was delayed. That makes the shortfall look more like spending pushed back in time than money saved.
Indeed, the company guided next-quarter capex above $50 billion. It also pointed to roughly $170 billion of investment for calendar 2026.
Operating cash flow rose 29% from a year earlier to $58 billion this quarter, but free cash flow was only $18.6 billion.
Even when operations generate more cash, the cash left for shareholders can shrink if capex rises faster. That is why the return on AI infrastructure spending matters so much.
Next-quarter guidance is strong too
Guidance for fiscal second-quarter 2027, given on the earnings call, is positive. Total revenue is guided to $96.0 billion to $97.1 billion, and Azure growth to 49% to 50% in constant currency.
In effect, the company expects Azure to hold a high growth rate and possibly accelerate further.
Not all of the $677 billion in commercial remaining performance obligations (RPO) will turn into revenue soon. The company expects to recognize about 30% over the next 12 months. Commercial bookings also fell 12% from a year earlier. The timing of large contracts and the strength of existing sales execution both deserve attention.
