Is Soaring AI CapEx Putting Microsoft Stock’s Valuation At Risk?

Microsoft (MSFT) trades at a premium to the market on earnings, sales, and cash flow, with strong cash conversion. Its Q4 2026 operating cash flow was $55.4B, but free cash flow was $19.6B after $35.8B in capital expenditures, primarily for AI infrastructure. Azure revenue grew 43% YoY, but gross margin fell to 67% due to shifting mix.
