Microsoft, AI Now Drives Revenue Growth

The Financial Spectator · Equity & AI Infrastructure

The market reacted sharply at the open. Microsoft, following a broadly positive pre-market session, began trading up nearly 14%. The reason goes beyond a simple beat on expectations: Azure accelerated, the added infrastructure capacity was absorbed rapidly, Copilot is broadening monetisation, and the company continues to generate cash while sustaining one of the largest investment cycles in its history.

1. A strong quarter even after one-off items

Fourth-quarter fiscal revenues reached $90.0 billion, up 18%. Operating income rose at the same pace to $40.6 billion, while the operating margin held at around 45%. GAAP net income grew 31% and diluted EPS 32%.

Reading the earnings figures, however, requires a distinction. The quarter benefited from a $3.2 billion gain on the investment in Anthropic and other discrete items, with a combined positive impact of $0.27 on EPS relative to prior guidance. Microsoft clarified that, stripping out these effects, revenue, operating income and EPS nonetheless exceeded its own forecasts. Adjusted EPS, excluding the impact of OpenAI investments, came in at $4.74, up 23%.

2. Azure converted capacity into revenue

Intelligent Cloud generated $39.3 billion, up 32%. Azure and other cloud services advanced 43%, ahead of prior guidance. Management's commentary was precise: demand continues to outpace available capacity, and every improvement in CPU and GPU efficiency, as well as every reduction in provisioning lead times, is monetised almost immediately.

During the quarter Microsoft added 31 new data centres, bringing the fiscal-year total to 88, and activated an additional gigawatt of capacity. The time required to bring new GPUs online in major regions was cut by nearly 50%. Copilot workload throughput also quadrupled since the start of the year.

3. The backlog provides visibility, with a caveat on OpenAI

\n The commercial remaining performance obligation reached $678 billion,\n growing 84%. The figure includes significant contracts with OpenAI, whose\n scale will make quarter-over-quarter comparisons more volatile.\n The underlying reading remains solid nonetheless: excluding OpenAI, the backlog\n grew 25%, while all of the quarter's sequential increase came from clients\n outside the frontier model developers.\n

\n Microsoft Cloud generated $59.3 billion in the quarter and $214.4 billion\n for the full fiscal year. Nearly 90% of annual cloud revenue comes from customers\n other than frontier AI companies. The figure alleviates concerns that growth\n depends exclusively on a handful of large contracts tied to model laboratories.\n

4. Copilot shifts from adoption to monetisation

\n Microsoft 365 Copilot has surpassed 30 million paid seats, with\n new activations more than doubling compared to the prior quarter.\n The go-to-market strategy is broadening: per-user licensing is being\n complemented by consumption-based pricing, creating a second revenue stream\n tied to intensity of use. Management views E5 and E7 bundles, Agent 365\n and consumption-based services as a pathway to ARPU growth through FY2027.\n

\n The momentum extends beyond Office. GitHub Copilot has 50 million users\n and its revenue accelerated more than 60% quarter-over-quarter following the\n introduction of consumption-based pricing. Foundry has reached 100,000 customers\n with revenue more than doubling. Agent 365 lists nearly 40 million agents.\n Microsoft is thus deploying AI from the data centre through to application\n software, with multiple monetisation layers across the same technology stack.\n

5. The infrastructure bill remains the most sensitive issue

\n In the quarter alone, Microsoft recorded $41 billion in CapEx, of which\n approximately two-thirds were allocated to short-lived assets, primarily CPUs and GPUs.\n Cash payments for property and equipment totalled $35.8 billion.\n Operating cash flow, at $55.4 billion and up 30%, left quarterly\n free cash flow of $19.6 billion.\n

\n For the full fiscal year, operating cash flow reached $182.9 billion.\n Cash investments in property and equipment rose to $115.9 billion,\n nearly double the prior year, leaving calculated free cash flow of approximately\n $67 billion. The financial engine retains considerable self-funding capacity,\n with over $43 billion returned to shareholders.\n

From FY2027, Microsoft will extend the estimated useful life of data centres and offices from 15 to 25 years. A portion of future contracts will shift from finance lease to operating lease classification; the latter remain economically significant, even though they fall outside the company's definition of CapEx. The expectation for calendar year 2026 is cited at around $175 billion, with no reduction in underlying infrastructure plans.

The 10-K reveals the scale of the commitments: net property and equipment of $313.1 billion, $329.1 billion in leases predominantly tied to data centres not yet commenced, and total contractual obligations of $743.8 billion, spread across multiple years and partially subject to conditions. The scale of the platform protects the competitive moat, but also raises the level of execution required.

6. The guidance completed the job

For the first fiscal quarter of 2027, Microsoft is guiding for revenues of between $89.85 billion and $90.95 billion, representing growth of 16–17%. Intelligent Cloud is expected in the range of $40.95–$41.25 billion, up 33–34%, while Azure is forecast to accelerate to approximately 45% in constant currency. Management anticipates even faster growth in the first half of the fiscal year.

7. Why Wall Street re-rated the stock

8. Risks that remain on the table

Conclusion: the quarter the market had been waiting for

Microsoft delivered strong results, guidance that exceeded the market's worst fears, and concrete evidence of AI monetisation. Azure is accelerating, Copilot is growing in both users and revenue, the backlog is expanding, and operating margins remain stable. The stock's reaction reflects a re-rating of the earnings trajectory, underpinned by greater visibility and a commercial model that combines licences with consumption.

The overall assessment remains balanced. The company is investing at an exceptional pace, cloud margins are under pressure, and infrastructure commitments are substantial. The success of the new cycle will hinge on the ability to convert backlog, data centres, and AI agents into recurring revenue and free cash flow. After this quarter, Microsoft has given the market more grounds to believe that conversion is already under way.
