- Microsoft reported record fiscal-year revenue surpassing $331 billion (+18% YoY), with Q4 revenue of $90 billion and EPS of $4.74 (up 23% adjusted for the OpenAI investment impact).
- Azure revenue grew 43% in Q4, pushing full-year Azure past $100 billion (+41%), with CFO Amy Hood attributing the acceleration to efficiency gains across the CPU and GPU fleet — though demand still exceeds available supply.
- M365 Copilot paid seats surpassed 30 million, with net seat adds more than doubling quarter-over-quarter as Microsoft expands billing from per-seat licensing to "seat-plus consumption" models.
- Commercial Remaining Performance Obligation grew 84% to $678 billion, signaling a massive backlog of contracted future revenue.
- Satya Nadella unveiled Project Perception, an agentic cybersecurity system using a multi-model approach — including the smaller MAI-Cyber-1-Flash model for 90% of tasks — to run continuous red, blue, and green team operations.
- Nadella emphasized model-swappable architecture, telling analysts Microsoft's platform separates the "harness" (memory, context) from the model, letting enterprises swap in Frontier, low-cost, or custom models without lock-in.
- Microsoft confirmed operating margins will decline slightly in FY27 due to continued AI infrastructure and R&D investments, while Windows OEM and Devices revenue is expected to drop in the high-teens.
Why it matters: The $678 billion RPO backlog — roughly 2x current annual revenue — is already locked in, but Azure's 43% growth remains capped by physical supply constraints, and the projected FY27 margin decline shows Microsoft's AI infrastructure bill is still climbing faster than near-term monetization can offset.
