Microsoft’s Azure Growth Supports a Higher Valuation, With a Margin Cost

UBS raised its Microsoft price target to $675 from $525 and kept a Buy rating, arguing that AI demand can sustain faster Azure growth. The valuation call rests on a real operating trend, but it should be tested against both revenue acceleration and the cost of supplying that growth.

Microsoft reported more than $331 billion of fiscal 2026 revenue, up 18%. Azure revenue exceeded $100 billion for the first time, and management said demand continued to exceed available supply. For the September quarter, the company guided Azure growth to about 45% in constant currency.

Growth and margin move in opposite directions

The same infrastructure investment that expands AI capacity has pressured cloud profitability. Microsoft Cloud gross margin fell as the company added data centers, chips and supporting systems, although efficiency gains offset part of the decline. That means faster Azure growth is not automatically worth a higher multiple if each new dollar requires disproportionate capital.

UBS’s case is that demand, improved supply and broader AI adoption can lift estimates enough to justify the valuation. The strongest evidence is not a single quarter of capacity-constrained growth. It is a sequence in which deployed infrastructure produces durable revenue, utilization rises and gross-margin pressure stabilizes.

What the next report needs to show

Investors should compare Azure growth with capital spending, cloud gross margin and management’s statements about capacity. Microsoft 365 Copilot adoption also matters because software revenue can improve the return on infrastructure that serves multiple products.

The risks are clear. Customers could optimize workloads, competitors could price aggressively, or new capacity could arrive after demand slows. Microsoft also has investment exposure to OpenAI that can affect reported earnings separately from operating performance.

A higher target is defensible if Azure remains supply-constrained for productive reasons and new capacity converts into high-margin usage. If capital intensity keeps rising without margin stabilization, the valuation debate will shift from demand to returns. The next earnings call should make that trade-off more visible.
