Microsoft (MSFT) delivered a blockbuster fiscal fourth-quarter report on Wednesday, July 29, that silenced skeptics and sent its stock soaring. The company's massive $41 billion quarterly investment in AI infrastructure finally showed clear returns, with Azure cloud growth accelerating to 43% and annual revenue surpassing $100 billion for the first time. Investors rewarded the company with an 8-10% surge in after-hours trading, adding approximately $257 billion to its market value.

A Quarter That Beat Across the Board

For the quarter ended June 30, Microsoft reported revenue of **$90.01 billion**, an 18% increase year-over-year and well above the $87.62 billion Wall Street had expected . Adjusted earnings per share came in at **$4.74**, significantly beating the $4.24 consensus forecast .

Net income soared 31% to **$35.77 billion**, or $4.81 per share, boosted by a $3.2 billion gain** from Microsoft's investment in AI company Anthropic and lower-than-expected costs from its voluntary retirement program . For the full fiscal year 2026, revenue reached **$331.8 billion, up 18%, while net income rose 31% to $133.7 billion .

Azure Steals the Show: $100 Billion Milestone

The star of the quarter was unquestionably Microsoft's Azure cloud business. Azure and other cloud services revenue grew 43% year-over-year, accelerating from 40% growth in the prior quarter and beating analyst expectations of approximately 40% . This marks Azure's fastest growth in four years .

Even more significantly, CEO Satya Nadella announced that **Azure's annual revenue surpassed $100 billion for the first time** in fiscal year 2026, up from $75 billion in the prior year . This milestone cements Azure's position as the second-largest cloud provider behind Amazon Web Services and well ahead of Alphabet's Google Cloud.

The Intelligent Cloud segment, which houses Azure, posted revenue of **$39.31 billion**, up 32% year-over-year and surpassing analyst expectations of $38.16 billion .

AI Products Show Commercial Traction

Beyond infrastructure, Microsoft's AI applications demonstrated strong adoption:

• Microsoft 365 Copilot reached over 30 million paid seats, up from 20 million in April .

• GitHub Copilot now has 50 million users, with revenue accelerating over 60% sequentially .

• Nadella highlighted that hundreds of enterprise customers have purchased millions of seats for high-end E7 productivity software bundles .

The $41 Billion Question: Capex and Returns

Microsoft's capital expenditures and finance leases for the quarter surged **69% year-over-year to $41 billion** . However, this came in slightly below analyst expectations of approximately $42.4 billion , providing some relief to investors worried about runaway spending.

The company also made two important accounting adjustments that effectively reduced its capital spending outlook: 

1. Extending data center and building useful lives from 15 to 25 years, which will reduce annual depreciation expenses .

2. Shifting more future data center leases to operating leases instead of finance leases .

These changes imply approximately **$175 billion** in capital expenditures and finance leases for 2026, compared to the prior $190 billion forecast . CFO Amy Hood expects further capex growth in fiscal 2027, driven by "demand signals across our portfolio" .

Despite the spending, free cash flow fell 23% to $19.64 billion. Hood assured investors that Microsoft expects to be free cash flow positive in fiscal 2027 .

Future Guidance and Commercial Backlog

For the fiscal first quarter of 2027, Microsoft projected:

• Revenue of $89.85 billion to $90.95 billion (approximately 16% growth at the midpoint) .

• Azure growth of approximately 45% at constant currency, above the 41.4% consensus .

The company's commercial remaining performance obligations (RPO)—contracted revenue not yet recognized—rose 8% sequentially to a massive $678 billion, driven by enterprise commitments outside of AI model developers . This provides exceptional visibility into future revenue.

Why the Stock Reacted Differently

Unlike Alphabet, which saw its stock plunge 7% after a strong cloud quarter due to spending concerns, Microsoft received a very different verdict . Key factors driving the rally included:

1. Capex came in slightly below expectations ($41B vs. $42.4B) .

2. The capex outlook was effectively lowered through accounting adjustments .

3. Azure growth demonstrably accelerated (43% vs. 40% prior quarter) .

4. Revenue and EPS beat expectations by significant margins .

5. Demand continues to exceed supply, suggesting pricing power .

As CFO Amy Hood stated, "When we can make efficiency gains, they are quickly monetized in quarter" . This ability to rapidly convert capacity into revenue is precisely what investors wanted to see, proving that Microsoft's historic AI bet is beginning to pay off.
