AI-CapEx share
Microsoft does not publish AI-only CapEx as a discrete line. Disclosure language in the MD&A attributes the bulk of FY24 increase to AI and cloud infrastructure. The CapEx-to-OCF ratio rose from roughly 24% in FY22 to roughly 38% in FY24 - the largest jump in the company's post-2014 history.
FCF margin
Revenue FY24 was approximately $245B; FCF margin equals 74.1 / 245 = 30.2%. The AI-CapEx ramp will compress this in FY25-FY26 even as revenue grows; treat flat-to-declining FCF margin as the base case for the next two years.
