AI capex (+45% YoY) is outrunning operating cash flow — FCF compressed despite +14.9% revenue growth

Azure (+34%) is the engine. Intelligent Cloud grew $18.8B (+21.5%) in absolute dollars — single-largest growth driver in the portfolio.

FCF down 3.3% YoY to $71.6B even as revenue rose $36.6B. Capex now consumes 47% of OCF, vs 37% prior year.

Sustainability hinges on Azure holding above 30% growth while capex moderates by FY27. Watch ROIC inflection.

BOTTOM LINE

Microsoft converts AI demand into revenue better than any peer, but Capex/OCF gap widening from 32% to 47% in two years is the single most important watch metric. If Azure growth dips below 25% while capex stays >$60B, FCF could turn negative on a TTM basis by FY27.
