Why investors are watching Microsoft after Satya Nadella delivered stronger AI and Azure results

Microsoft gave investors stronger evidence that its massive artificial intelligence investments are producing real business growth. Azure accelerated, Microsoft 365 Copilot passed 30 million paid seats, and the company delivered better revenue and profit than Wall Street expected.

The results helped Microsoft shares jump 18% in one week after a difficult start to 2026. The rally reflected renewed confidence that Microsoft can turn spending on data centers, chips and AI products into dependable revenue.

The quarter was strong, but investors still need to examine cloud margins, capital spending, OpenAI exposure and the quality of Microsoft’s backlog.

What made Microsoft’s quarter stand out?

Microsoft’s fourth-quarter results stood out because growth accelerated while the company continued spending heavily on AI infrastructure. Revenue increased 18% from the previous year to $90 billion, beating the expectations cited before the report.

Reported net income rose 31% to $35.8 billion, while diluted earnings per share increased 32% to $4.81. However, adjusted net income excluding the effects of Microsoft’s OpenAI investments grew by a more moderate 22%.

The quarter closed a record fiscal year in which Microsoft generated more than $331 billion in revenue, an increase of 18%. Microsoft Cloud revenue surpassed $214 billion for the year after growing 27%, according to the company’s official earnings call.

Azure became the largest reason for investor excitement after its annual revenue passed $100 billion for the first time. The business grew 41% for the full fiscal year, showing that demand extended beyond one unusually strong quarter.

Microsoft 365 Copilot also passed 30 million paid seats, while net paid seat additions more than doubled from the previous quarter. Copilot and other premium Microsoft 365 products helped lift average revenue per user, suggesting that Microsoft can charge more as customers adopt advanced features.

Not every part of the company performed well because More Personal Computing revenue fell 4%. Windows OEM and Devices revenue declined 7%, while Xbox content and services revenue dropped 10%, leaving Azure and Microsoft 365 responsible for more of Microsoft’s growth.

Why did Azure accelerate so sharply?

Azure accelerated because demand remained greater than Microsoft’s available computing capacity, while the company improved how quickly it used new infrastructure. Those improvements allowed Microsoft to sell additional cloud capacity as soon as it became available.

Azure and other cloud services revenue grew 43% during the quarter, compared with 40% in the previous quarter. Microsoft said the increase exceeded its expectations because engineers improved the efficiency of its existing CPU and GPU fleet.

Microsoft also reduced the time needed to bring new GPUs online in its largest regions by nearly 50% during the fiscal year. It added 31 data centers across five continents during the quarter and brought another gigawatt of computing capacity online.

These numbers require an important distinction because Azure did not generate $39.3 billion in quarterly revenue by itself. The broader Intelligent Cloud segment generated $39.3 billion, while Microsoft disclosed Azure’s growth rate without providing its exact quarterly revenue.

Microsoft’s Azure metric also includes several related cloud services, such as GitHub cloud offerings, Nuance Healthcare and virtual desktop products. Stronger GitHub Copilot usage contributed to quarterly growth after Microsoft changed its pricing model to connect charges more closely with usage.

Management expects Azure growth to reach about 45% in constant currency during the first quarter of fiscal 2027. Demand still exceeds supply, so the pace of growth may depend partly on how quickly Microsoft can provide electricity, equipment, and completed data center space.

Fun fact: Microsoft’s cloud computing platform Azure has long been the second-most-used cloud computing platform in the world, behind Amazon’s (NASDAQ: AMZN) AWS but ahead of Alphabet’s (NASDAQ: GOOGL) Google Cloud Services. 

Can Microsoft’s backlog sustain growth?

Microsoft’s backlog offers strong evidence that cloud demand could remain elevated, but investors should not treat it as immediate revenue. Commercial remaining performance obligation increased 84% to $678 billion at the end of fiscal 2026.

Remaining performance obligation represents contracted revenue that Microsoft expects to recognize after delivering future products and services. The backlog had an average duration of 2.3 years, with about 30% expected to become revenue during the following 12 months.

The backlog also includes major commitments connected with OpenAI, which can make the reported growth rate look unusually high. Excluding OpenAI, Microsoft said commercial remaining performance obligation still increased 25%, reflecting broader customer demand.

All sequential backlog growth during the quarter came from customers outside frontier model companies. Microsoft Cloud also generated nearly 90% of its annual revenue from customers outside that group, reducing concerns that its growth depends entirely on a few AI developers.

OpenAI remains financially important because Microsoft reported $24.1 billion in fiscal 2026 revenue from its commercial arrangements with the company. Microsoft also held an approximately 25% interest in OpenAI and reported $6 billion in related accounts receivable at the end of June.

Nadella is reducing dependence on any single model by building Azure to support commercial open and customer-created AI systems. If customers switch between models while keeping their applications and data on Azure, Microsoft can continue earning cloud revenue regardless of which AI developer leads the market.

Fun fact: Microsoft returned $10.2 billion to shareholders in the form of dividends and share repurchases in the fourth quarter of fiscal year 2026.

What costs are hiding behind the AI boom?

The highest cost behind Microsoft’s AI growth is its rapidly expanding investment in chips, servers and data centers. Capital expenditures reached $41 billion during the fourth quarter, with about two-thirds directed toward shorter-lived assets such as CPUs and GPUs.

Microsoft separately reported $35.8 billion in quarterly cash payments for property and equipment. Its fiscal 2026 Form 10-K shows full-year additions to property and equipment of approximately $115.9 billion, up from $64.6 billion one year earlier.

Heavy spending affected cash generation even as customer payments remained strong. Operating cash flow rose 30% to $55.4 billion during the quarter, but free cash flow reached only $19.6 billion after accounting for property and equipment purchases.

AI spending also pressured profitability inside Microsoft’s cloud business. Microsoft Cloud’s gross margin fell to 65% for the quarter from 68% one year earlier, while its full-year margin declined to 66% from 69%.

Microsoft has some flexibility because CPUs and GPUs can be purchased closer to the time they are needed. If AI demand weakens, management says it can slow equipment purchases or delay parts of data center projects before committing all planned spending.

Physical constraints remain a larger concern because data centers require reliable electricity, suitable land, permits, networking equipment and trained workers. Microsoft warns that power shortages, grid connection delays and local opposition could slow expansion or raise infrastructure costs.

What should investors watch next?

Investors should first watch whether Microsoft can deliver the stronger fiscal 2027 growth described in its outlook. Management expects first-quarter revenue between $89.85 billion and $90.95 billion, representing growth of approximately 16% to 17%.

Intelligent Cloud revenue is expected to reach between $40.95 billion and $41.25 billion, with Azure growth near 45% in constant currency. Microsoft also expects capital expenditures above $50 billion during the quarter as it continues expanding capacity.

Copilot adoption will be another major test because the paid seat milestone does not reveal the full business picture. Microsoft has not disclosed Copilot’s standalone revenue, active usage, customer renewal rates or the percentage of eligible Microsoft 365 users paying for it.

Investors should also monitor cloud margins as AI usage rises. Faster Azure and Copilot growth will be less valuable if equipment, electricity and computing expenses continue increasing faster than Microsoft’s ability to improve efficiency or adjust pricing.

Valuation matters after Microsoft shares jumped 18% in a week and erased their earlier 2026 decline. Investors should compare the latest share price with updated earnings and free cash flow estimates instead of relying on an outdated P/E ratio from before the rally.

Microsoft’s quarter showed that AI demand is producing measurable Azure growth, but the next stage will be harder. The company must convert its backlog, expand Copilot adoption, and control infrastructure costs to prove that the AI boom can create durable shareholder returns.
