MICROSOFT Q4 FY26 earnings call MSFT

Microsoft significantly expanded its AI infrastructure, adding 31 new data centers this quarter for a total of 88 this fiscal year, and bringing another gigawatt of capacity online. The company aims to roughly double its overall capacity in two years, driven by accelerating demand. Efficiency gains, such as a 50% reduction in dock-to-live times for new GPUs and a 4x increase in Copilot workload throughput, are key to monetizing this expansion. Microsoft is also modernizing its fleet with proprietary silicon like Maia 200 (delivering 30% better performance per dollar) and Cobalt VMs, alongside next-gen hardware from NVIDIA and AMD.

The company emphasizes model choice, offering over 11,000 models from various providers, including its own MAI family. MAI models are co-designed with silicon, achieving 40% better performance per watt on Maia 200. This approach focuses on cost-efficient inference and business continuity, allowing models to be substitutable. Examples include MAI-Code-1-Flash in GitHub Copilot (higher acceptance, 10% lower token usage) and Excel (comparable quality to GPT-5.6 at lower cost), and MAI-Cyber-1-Flash in security (better performance than Mythos at half the cost).

Microsoft is evolving its data estate to support agents, with AI-optimized databases like Cosmos DB and PostgreSQL seeing rapid adoption (PostgreSQL revenue up 55%). Fabric now has over 40,000 paid customers, and Foundry, the complete app and agent stack, has 100,000 customers with revenue more than doubling year-over-year. The company introduced HorizonDB (managed PostgreSQL) and Rayfin (agent-first SDK for Fabric), and Web IQ to give agents access to real-world intelligence. Agent 365, a control plane for governance, identity, and security, has nearly 40 million registered agents across tens of thousands of companies.

M365 Copilot reached over 30 million paid seats, with net seat adds more than doubling sequentially. User satisfaction scores doubled over the last three quarters, and latency was cut by 25%. The product is evolving into a 'super app' with chat, Cowork, Autopilot, and Code experiences. Monetization is shifting to a 'per seat plus consumption' model, with usage-based billing added to Cowork and GitHub Copilot. The new E7 suite, integrating Copilot, E5, Entra, and Agent 365, has seen rapid adoption, with EY deploying it to 400,000 employees.

Microsoft launched Frontier Co., an outcome-driven engineering organization with 6,000 experts embedded with customers to co-design and continuously improve AI systems. This initiative has completed over 330 projects with 164 customers. In healthcare, the company automated 28 million patient encounters this quarter, aiming for 100 million this calendar year. Xbox is undergoing a business reset to return to growth in FY27, while Windows focuses on quality, fundamentals, and secure edge AI. LinkedIn continues strong engagement with double-digit member growth and AI-powered solutions for recruiters.

Microsoft delivered strong FY26 results with 18% revenue growth and 21% operating income growth. Q4 revenue was $90 billion, up 18%, with non-GAAP EPS up 23%. Commercial bookings (ex-OpenAI) grew 18%, and Microsoft Cloud revenue grew 27%. The company provided FY27 guidance for double-digit revenue and operating income growth, with CapEx expected to grow year-over-year. A change in the estimated useful life of data centers and office buildings from 15 to 25 years will impact future depreciation and shift some CapEx reporting from finance to operating leases.
