Microsoft Stock Has One Thing Left To Prove

For questions about this article or underlying research, email help@trefis.com.

Microsoft (MSFT) says customer demand for cloud capacity exceeds its available supply, and some third-party capacity expected in the September quarter was delayed. Management now expects a portion of that capacity to arrive in the second half of its fiscal year, leaving the shortage unresolved. You need to know first which part of Microsoft is short, and how much revenue comes from it.

Microsoft’s Capacity Shortage Is In Azure

Even with the delayed third-party deliveries, management said Azure revenue grew 48% in fiscal Q1 2027, the quarter that ended September 30, 2026. Management cited Foundry, Microsoft’s platform for building AI solutions, alongside earning more on its processors as drivers of that growth. During the October 28, 2026 call, analysts asked how Microsoft would earn a return as it adds AI capacity, and what was behind the AI demand in Azure. Addressing returns, Microsoft’s Satya Nadella pointed to both running Azure more efficiently and earning more from each workload. He said Microsoft wants a single pool of capacity that is as efficient and interchangeable as possible.

Azure is part of the Microsoft Cloud, which generated $63.9 billion of the company’s $92.3 billion in revenue that quarter. That accounts for more than two-thirds of Microsoft’s sales. Growth for Microsoft Cloud accelerated to 30%, compared with 19% for the company as a whole. Azure brings in only a portion of that total, which also includes M365 Commercial Cloud.

What Has Microsoft Said About Its Capacity Delays?

Management has said customer demand continues to exceed available supply, and that some supply it had counted on for the December quarter has also moved into the second half of the fiscal year. Even so, the company expects Azure revenue to grow 49% to 50% in the December quarter, excluding currency swings, with efficiency gains across its fleet of chips helping to offset some delayed GPU contracts.

Microsoft is paying heavily for the build-out. Management expects capital spending of about $170 billion for calendar 2026, a total it said reflects the third-party delays. It expects spending to speed up in the second half of its fiscal year, including the third-party deliveries that shifted there. Free cash flow was $18.6 billion in fiscal Q1 2027, down from $25.7 billion a year earlier, a drop management put down to higher capital spending. It still expects free cash flow to stay positive in fiscal 2027.

The Azure guide covers only the December quarter. Management also said token pricing, which is what customers pay per unit of AI output, could change during the quarter.

When Will Microsoft Report Azure’s Next Growth Rate?

Microsoft is expected to report its fiscal Q2 2027 results, covering the December quarter, in January 2027. The number to watch in that report is Azure’s growth rate, set beside management’s guide for the quarter on the same basis, excluding currency swings.

How Much Microsoft Do You Already Own?

If you own an S&P 500 or Nasdaq fund, you already own Microsoft, alongside the same few giants that lead those funds. The Trefis High Quality (HQ) Portfolio takes a different route: 30 quality companies in equal weight, so no single stock dominates. Since its inception in September 2020 it has returned 105%, ahead of a benchmark that combines the S&P 500, S&P Mid-cap and Russell 2000.
