Is Microsoft a Buy After Its Latest Earnings Report?

Microsoft rallied 8% in after-hours trading following fourth-quarter 2026 earnings that topped expectations, with revenue climbing 18% year-over-year to $90 billion and operating income rising 18% to $40.6 billion. Azure cloud services delivered 43% year-over-year revenue growth, continuing to drive the company's margin expansion.

The market's reaction hinged as much on what Microsoft didn't do as what it reported. The company held its annual capital expenditure forecast steady at $175 billion, while rivals Alphabet and Meta both raised their spending guidance in recent weeks. That discipline signals confidence in extracting returns from existing infrastructure investments, particularly around AI compute capacity, rather than chasing growth through additional outlays.

The spending divergence matters. Elevated capex has weighed on Alphabet and Meta shares as investors question profitability timelines for AI investments. Microsoft's unchanged guidance positions it as the disciplined player in the hyperscaler race, a narrative that resonated immediately in extended trading.
