Key Earnings Metrics

Microsoft delivered a record fiscal year with revenue growth holding at 18% for both the quarter and the full year. The quarter benefited from several discrete items, including a $3.2 billion gain from the Anthropic investment, which added $0.27 per share above prior guidance.

• Q4 revenue: $90 billion, up 18% (17% in constant currency). Growth was driven by Azure platform demand and first-party AI applications.
• Annual revenue: $331 billion, up 18%. Growth accelerated compared to prior year, reflecting sustained cloud and AI demand.
• Microsoft Cloud: $214 billion annually, up 27%. Cloud now represents roughly two-thirds of total company revenue.
• Azure: surpassed $100 billion annually, up 41%. This is the first time Azure has crossed the $100 billion annual run rate.
• Operating income: $155 billion-plus, up 21%. Operating income growth outpaced revenue growth, reflecting operating leverage despite heavy AI infrastructure investment.
• Q4 EPS: $4.74, up 23% adjusted for OpenAI investment impact. Discrete items added $0.27 per share, partially offset by Xbox impairment and severance charges.

Management Commentary

Satya Nadella framed the year around two goals: ensuring AI empowers individuals and helping organizations build continuous learning loops without outsourcing their core intellectual property. This framing positions Microsoft as the infrastructure and platform layer for enterprise AI sovereignty rather than just a model provider.

Nadella highlighted infrastructure scale, noting 31 new data centers added this quarter and 88 for the full year across five continents. Dock-to-live times for new GPUs in the largest regions dropped nearly 50% year over year, and the company added another gigawatt of capacity this quarter. Microsoft remains on track to roughly double overall capacity within two years.

On the Copilot side, paid Microsoft 365 Copilot seats exceeded 30 million, with net seat adds more than doubling quarter over quarter. User satisfaction scores doubled over three quarters and reached an all-time high. The number of customers with more than 50,000 seats increased over 7x year over year, and enterprise customers deploying Copilot to the majority of their information workers grew nearly 75% quarter over quarter.

Amy Hood reported that operating income growth outpaced revenue growth at 21%, reaching more than $155 billion. She noted that several discrete items benefited Q4 results by $0.27 per share, including the $3.2 billion Anthropic gain and lower voluntary retirement program expenses, partially offset by Xbox impairment and severance charges. Her forward outlook commentary was cut off in this excerpt, so explicit guidance figures were not available.

Hood also emphasized that the business model is evolving beyond per-seat pricing to per-seat plus consumption. This applies to Copilot Cowork, GitHub Copilot, and Dynamics 365 customer service, where usage-based credit consumption increased 4x quarter over quarter.

Strategic Implications

The most consequential strategic shift is the move from per-seat to per-seat-plus-consumption pricing. This changes the revenue trajectory for Microsoft's AI products because customers who deepen usage pay more over time, even if seat counts plateau. GitHub Copilot already introduced usage-based billing, with Copilot revenue accelerating over 60% quarter over quarter after the new model took effect.

On infrastructure, Microsoft is investing heavily to stay ahead of demand. The company is deploying next-generation rack-scale AI infrastructure based on AMD Helios and NVIDIA Vera Rubin, and its own Maia 200 silicon delivers 30% better performance per dollar than the prior generation. Cobalt CPU VMs are scaling across more than 25 data centers by month-end, supporting both first-party and customer workloads.

The model strategy is explicitly multi-provider. Microsoft offers over 11,000 models through its catalog, and the number of customers using models from multiple providers increased 5x since the start of the year. The company's own MAI model family is being co-designed with silicon, achieving 40% better performance per watt on Maia 200. This architecture makes models substitutable, which addresses both cost efficiency and business continuity concerns.

Foundry, the enterprise AI platform, now has 100,000 customers with revenue more than doubling year over year. The number of Foundry customers at a 1 trillion token annualized run rate increased 4x year over year. Agent 365, the governance and control plane for agents, has nearly 40 million agents registered across tens of thousands of companies just two months after launch.

The new E7 suite, which bundles Copilot E5, Entra, and Agent 365, has already attracted hundreds of enterprise customers. EY deployed E7 to 400,000 employees in the largest win to date. This bundling strategy mirrors the historical Office 365 and Microsoft 365 approach of consolidating workloads into integrated suites.

Microsoft also launched Microsoft Frontier Company, embedding 6,000 industry and engineering experts with customers for outcome-driven AI co-design. Over the past year, this team completed more than 330 projects across 164 customers, including work with Novo Nordisk on clinical data analysis and LSEG on financial content search.

The Mistral partnership brings models to Microsoft Sovereign Cloud across public, customer-controlled, and fully disconnected environments. This directly addresses AI sovereignty concerns, particularly for government and regulated industries that cannot rely solely on public cloud deployments.

Xbox remains a drag, with impairment charges and severance expenses impacting Q4 results. Nadella expressed confidence in returning the business to growth in fiscal 2027, but the reset is still in progress.

What to Watch Next

I would watch four things over the next two quarters:

• Consumption revenue trajectory: The shift to per-seat-plus-consumption is early. If usage-based billing in Copilot Cowork, GitHub Copilot, and Dynamics 365 customer service continues to scale, it validates the model change and expands total addressable market beyond seat counts.
• Azure growth durability above 40%: Azure grew 41% annually and surpassed $100 billion. Sustaining growth above 40% at this scale requires continued AI workload migration and capacity delivery. Any deceleration would reflect either supply constraints or demand softening.
• Copilot seat expansion into large enterprises: The 7x year-over-year increase in customers with more than 50,000 seats is the leading indicator for whether Copilot becomes standard enterprise infrastructure. NHS England, KPMG, and HSBC deployments provide reference cases, but renewal and expansion rates will matter more than initial seat purchases.
• Foundry and Agent 365 adoption depth: Foundry has 100,000 customers and Agent 365 has 40 million registered agents. The question is whether these translate into durable consumption revenue or remain experimental. The 4x increase in customers at 1 trillion token run rate is the metric to track for production-grade usage.
