Microsoft’s earnings report delivered a mixed signal that unsettled investors and triggered the company’s sharpest one-day share price decline since 2020.
The stock slid around 10% on Thursday and showed little sign of recovery in Friday’s pre-market session, trading just 0.55% above the previous close.
That reaction came despite Microsoft beating analyst expectations on overall revenue, highlighting how investor attention has narrowed to a specific part of the business.
The focus was firmly on Azure and the company’s broader cloud operations.
As artificial intelligence spending accelerates across the tech sector, cloud performance has become the key metric investors use to judge whether massive infrastructure investments are delivering the returns they expect.
Azure growth becomes the focal point
Azure and other cloud services recorded growth of 39% during the quarter, narrowly missing StreetAccount’s consensus forecast of 39.4%.
While the shortfall was small, it marked a slowdown from the 40% growth seen in the previous fiscal quarter, and that deceleration carried outsized importance for the market.
For many investors, Azure growth has become shorthand for Microsoft’s success in commercialising AI.
The company has poured billions into data centres, chips, and supporting infrastructure, similar to other hyperscalers.
When cloud growth softens, even slightly, it raises questions about whether demand is keeping pace with the scale of spending.
That sensitivity was underlined by market comparisons on the same day.
Meta reported heavy AI investment but saw its shares jump 8%, reinforcing the idea that investors are rewarding companies where spending appears to translate more directly into near-term momentum.
Capacity constraints shape results
Microsoft pointed to internal capacity decisions as a factor behind Azure’s performance.
The company said cloud results could have been stronger if more data centre infrastructure had been allocated to customers instead of being reserved for internal needs.
This trade-off reflects how AI is reshaping cloud economics. A growing share of computing capacity is being consumed by Microsoft’s own AI development and first-party products, limiting what can be immediately offered to external clients.
While this may support higher-margin services over time, it can restrict short-term cloud growth.
As AI workloads expand, capacity management is becoming a structural issue rather than a temporary bottleneck. Investors appear increasingly alert to how these internal demands influence reported cloud figures.
Margins and guidance add pressure
Beyond Azure, Microsoft’s forward guidance also contributed to the cautious response.
The company flagged an implied operating margin for the third quarter that fell short of market expectations.
Revenue guidance for the More Personal Computing segment, which includes Windows, came in at about $12.6 billion.
That figure was notably below StreetAccount’s $13.7 billion consensus, adding to concerns about near-term profitability as AI-related costs remain elevated.
The combination of softer cloud growth and weaker segment guidance reinforced the perception that Microsoft’s investment cycle is weighing on margins, even as revenue continues to expand.
