The setup
Microsoft reported its first quarter of fiscal 2027 on : revenue of $92.28B, up 19%, operating income of $45.92B, up 21%, and GAAP diluted earnings of $4.92 a share, up 32%. Azure grew 48%. Commercial remaining performance obligation, the contracted backlog, rose 73% to $677B. On those lines it was the best quarter Microsoft has printed, and the press release says results "exceeded expectations across revenue, operating income, and earnings per share."
Our read is narrower. Two of those numbers are not what they look like. The 49.76% operating margin, the highest of the nine quarters on this page, was earned partly on capacity that did not show up: capital spending including finance leases came in at $45.2B against the company's own guide of more than $50B (call commentary, not in the filing), because third-party capacity deliveries slipped, and depreciation rose $0.8B on the quarter after $1.3B in the quarter before. And the growth now leans on one customer. The 10-Q says Microsoft booked $10.0B of revenue from commercial arrangements with OpenAI in the quarter. That is 10.84% of revenue. A year ago the 10-K could say no single customer was 10% of sales; at this run rate the fiscal 2027 10-K cannot.
Our call: at the January report for the December quarter, operating income comes in below the $45.92B of this quarter, the first sequential decline in the nine quarters on this page, as the delayed capacity lands and starts to depreciate, and OpenAI revenue stays at or above 10% of total revenue. We are wrong if December-quarter operating income is at or above $45.92B, which would mean the margin was earned, not borrowed from the delay.
The stock barely moved on the print: about $528.50 at midday on against a $531.01 close the day before (Robinhood quote, market data). The tape has decided the quarter was fine. The page argues that it was fine for a reason that reverses next quarter.

All figures are from the Form 8-K Exhibit 99.1 and the Form 10-Q filed on , the recast annual statements in the second Form 8-K filed the same day, and the earlier 10-Q and 10-K filings listed in the Sources ledger. The June quarter is not reported on its own; it is the fiscal year less the three reported quarters, and the page says so wherever it is used.
Two things changed in the presentation this quarter, and both matter for reading the series. First, the segments. Microsoft dropped the three-segment structure it had used for years (Productivity and Business Processes, Intelligent Cloud, More Personal Computing) and now reports two: Agents and Infra, which brings together "our applications and agents, our multi-model system, and Azure infrastructure," and Devices and Consumer. Second, the Azure line. The 10-Q now defines Azure revenue as consumption across "non-GPU workloads" and "GPU workloads, including GPU infrastructure-as-a-service and Foundry." The old line was "Azure and other cloud services." So the 48% is measured against a recast $22,384M, not against the old base, and it is not directly comparable with the 39% to 43% the old line printed through fiscal 2026. The acceleration may be real; the filing does not let a reader prove it on a like-for-like basis.
Below the operating line the quarter was quiet. Other income was +$38M, against −$3,660M a year ago, when Microsoft took $4.1B of losses on its OpenAI investment. This quarter it booked $272M of OpenAI gains. That is why GAAP net income grew 32% and non-GAAP 18%: the year-ago base was depressed by the OpenAI mark, not because this quarter was flattered. The tax rate was 20.29%, against 19.11%.
