Microsoft Stock Jumps 7% After Hours on Fourth-Quarter Earnings Beat, Azure Growth Hits 43%

Since Microsoft's Azure cloud unit crossed $100 billion in annual revenue earlier Wednesday, the company followed up with its full fiscal fourth-quarter report after the market closed, and investors liked what they saw. Shares jumped 7% in extended trading, according to CNBC.

The quarter, which ended June 30, showed revenue growth of about 18% year over year, according to Microsoft's statement. Net income came in at $35.77 billion, or $4.81 per share, up from $27.23 billion, or $3.65 per share, a year earlier.

Part of that jump came from a one-time item: a $3.2 billion gain tied to Microsoft's investment in AI lab Anthropic. The company also said costs from its first-ever voluntary retirement program came in lower than expected. Working against those gains, Microsoft's Xbox gaming business took an impairment charge.

Azure Keeps Accelerating

The Intelligent Cloud segment, which houses Azure, posted $39.31 billion in quarterly revenue, up 31.6% year over year and ahead of the $38.16 billion analysts polled by StreetAccount had expected. Azure's own growth rate accelerated to 43%, according to CNBC.

The acceleration signals that enterprise AI spending is translating into actual cloud consumption, not just announcements and pilot projects. Commercial remaining performance obligations, Microsoft's measure of contracted but unearned revenue, rose 8% from the prior quarter to $678 billion. Microsoft said the sequential growth came from clients outside the AI model-developer category, meaning ordinary businesses are signing bigger cloud contracts, not just OpenAI and its peers.

The Spending Keeps Climbing Too

Capital expenditures and finance leases hit $41 billion for the quarter, up 69% from a year earlier. Free cash flow fell 23% to $19.64 billion as a result.

Finance chief Amy Hood reiterated that 2026 capital spending plans will hold steady, but she also disclosed an accounting shift. Microsoft will now depreciate office and data center buildings over 25 years instead of 15, and will shift more future data center leases from finance leases to operating leases. That change alone works out to roughly $175 billion in capital expenditures under the new framework, according to Hood's comments reported by CNBC.

Looking further out, Hood said she expects capital expenditures to grow again in fiscal 2027, citing what she called "demand signals across our portfolio." She also said she expects Microsoft to turn free-cash-flow-positive again in fiscal 2027, an implicit admission that the current spending pace is squeezing cash generation right now.

The OpenAI Concentration Problem

Microsoft is still leaning heavily on one customer. The company disclosed in January that roughly 45% of its $625 billion in commercial remaining performance obligations were tied to OpenAI.

Deutsche Bank analysts, who recommend buying Microsoft stock, flagged that as "some concentration risk" in a note last week, particularly given the rise of cheaper open-source AI models that could reduce demand for OpenAI's proprietary systems. If open-source alternatives start eating into OpenAI's business, Microsoft's biggest single revenue commitment gets shakier.

CEO Satya Nadella is also juggling a real allocation problem inside his own data centers. Every AI chip devoted to model training for research is a chip not available for Azure cloud customers or for running Microsoft 365 Copilot. The tradeoff is happening in real time as demand outpaces the company's ability to build data center capacity.

The Stock's Rough Year, Now Reversing

Context matters here. As of Wednesday's close, before the earnings jump, Microsoft shares were down 19% for 2026 while the S&P 500 was up about 7%. Investors have been punishing legacy software companies all year on fears that generative AI will disrupt their business models rather than boost them.

Wednesday's 7% after-hours pop doesn't erase that gap, but it signals that at least some of the market's AI-disruption fears may have been overdone for a company that's also one of the biggest AI infrastructure providers on the planet.

The open question going into fiscal 2027: can Microsoft actually hit positive free cash flow again while capital spending keeps climbing, and does its OpenAI dependency become a liability if the open-source AI competition Deutsche Bank flagged actually eats into that relationship. Microsoft's next quarterly report will be the first real test of whether the accounting changes Hood outlined smooth out the numbers or just delay the reckoning.
