Microsoft Corporation (NASDAQ:MSFT) capped a remarkable week on Friday, with shares closing at $464.72, up 3.02% for the session and an impressive 21.8% for the week. The surge followed the company's fiscal fourth-quarter earnings release on Wednesday, which revealed a staggering $678 billion in commercial remaining performance obligations (RPO) — an 84% increase year-over-year. This contracted revenue backlog, which represents future services to be delivered, has become a key metric for investors assessing the sustainability of Microsoft's AI-driven growth.
The weekly gain added approximately $617 billion to Microsoft's market capitalization, with Thursday's session alone accounting for a record single-day increase of nearly $450 billion. This dramatic re-rating was largely fueled by the disclosure of the massive backlog, which underscores the strength of enterprise demand for Microsoft's cloud and AI offerings, particularly Azure.
According to Microsoft's management, about 30% of the commercial RPO is expected to be recognized as revenue within the next twelve months. This translates to roughly $203 billion, or approximately 61% of the projected fiscal 2026 revenue. While this figure is based on independent calculations rather than official guidance, it highlights the company's robust revenue visibility. In comparison, Amazon's AWS backlog stands at $496 billion, and Alphabet's Google Cloud at $514 billion, though Microsoft's RPO includes a broader range of products.
Azure Growth Outpaces Expectations
Azure continued to be the primary growth engine, with revenue expanding 43% in the quarter, surpassing consensus estimates by 3 percentage points. For the upcoming quarter, Microsoft forecasts Azure growth of around 45% on a constant currency basis, well above the 40.92% consensus. This optimistic outlook reflects sustained customer demand, which CEO Satya Nadella noted continues to outpace the company's computing capacity. During the quarter, Microsoft opened 31 new data centers to support this demand.
The company's overall results also exceeded Wall Street expectations. Fourth-quarter revenue reached $90.00 billion, up 2.7% from consensus, while adjusted EPS came in at $4.74, beating estimates by 11.8%. For the first quarter of fiscal 2026, Microsoft guided revenue to approximately $90.40 billion, slightly above the $89.66 billion consensus.
Cash Flow Constraints and Investment Phase
Despite the strong demand signals, Microsoft's cash flow metrics revealed the pressures of its heavy investment phase. Capital expenditures totaled $41.0 billion in the quarter, representing 45.6% of revenue, while free cash flow fell to $19.6 billion, a 23% decline year-over-year, with a margin of 21.8%. Management indicated that first-quarter capital spending would exceed $50 billion, reflecting updated lease accounting. This aggressive investment is aimed at expanding AI infrastructure, but it has raised concerns about near-term profitability.
Copilot and Other Segments
Microsoft's AI monetization extends beyond Azure. The number of paid Microsoft 365 Copilot seats surpassed 30 million, up from 20 million in the previous quarter, providing an additional revenue stream from its AI investments. However, More Personal Computing revenue declined 4%, and Xbox content and services revenue fell 10%, indicating softness in consumer segments.
The contrasting cloud earnings from Microsoft, Amazon, and Alphabet highlight divergent growth trends and spending strategies. While Microsoft's backlog leads the pack, the company faces risks from elevated capital spending and a challenging PC and gaming market. Management has guided that the margin reduction in fiscal 2027 will remain under one percentage point, aiming to balance growth with profitability.
Looking ahead, Microsoft's near-term focus will be on converting its substantial backlog into Azure revenue growth while managing margin pressures. Investors will closely monitor the July manufacturing ISM report on Monday and the U.S. jobs report on Friday for broader economic signals. The company's next investor event is scheduled for August 27.
