Microsoft Corporation Azure Revenue Surpasses $100 Billion Milestone

Following intense investor scrutiny over artificial intelligence spending, Microsoft Corporation reported fiscal fourth-quarter revenue of $90 billion, an 18% year-over-year increase that exceeded Wall Street estimates. The results were anchored by the Azure cloud platform, which surpassed $100 billion in annual revenue for the first time and grew 43% year-over-year. Microsoft 365 Copilot also saw rapid adoption, reaching over 30 million paid seats by the end of June.

To sustain this growth, the company is aggressively expanding its AI infrastructure, signing $130 billion in new data center leases during the quarter. To manage the resulting financial impact, Microsoft Corporation extended the estimated useful life of its data centers from 15 to 25 years, shifting future leases from finance to operating leases. This accounting change adjusted the calendar year 2026 capital expenditure guidance to $175 billion. Despite these shifts, quarterly capex rose 70% to $41 billion, causing quarterly capital expenditures to exceed free cash flow for the first time since the AI buildout began.

CEO Satya Nadella announced a strategic shift toward designing in-house AI models and custom chips to reduce reliance on external suppliers like Nvidia. Nadella stated that these proprietary chips yield 40% better performance per watt. While the cloud segment flourished, the More Personal Computing division declined 4% due to a slump in Xbox hardware and services. In response, the gaming division is implementing a 100-day reset plan. The company's stock rose significantly in after-hours trading, reflecting investor confidence in the commercialization of its AI investments.
