Microsoft reported record earnings in the March quarter, driven by a 40% jump in Azure and a $37B AI run rate, underscoring the sector's resilience amid supply chain volatility. In an industry where AI infrastructure spending has surged, the cloud giant's performance highlights how capital allocation can translate into robust financial results even as data center construction and hardware deliveries face timing challenges. Revenue rose 18% to $82.9 billion, beating the $81.4 billion consensus, while earnings per share climbed 23% to $4.27. Azure grew 40% year-over-year, and the company's AI business reached a $37 billion annual run rate, up 123% from a year ago. Capital spending fell to $31.9 billion from $37.5 billion, reflecting the timing of data center construction rather than a slowdown in demand. Microsoft 365 Copilot now exceeds 20 million paid seats, up from 15 million, representing about 4.4% of the commercial base. Microsoft Cloud revenue, which includes Azure, 365, LinkedIn, and Dynamics, rose 29% to $54.5 billion, and the backlog of performance obligations stood at $627 billion, heavily tied to OpenAI. Looking ahead, Microsoft's disciplined capital spending and expanding AI and cloud services position it to sustain growth, leveraging its sizable backlog and strategic partnership with OpenAI to navigate ongoing supply chain disruptions.
