How did MSFT's Q4 2025 free cash flow of $136,162 million compare to analyst estimates, given its operating income growth?

It appears there might be a misunderstanding regarding the figure you provided. Microsoft's reported cash from operating activities for the full fiscal year 2025 (ending June 30, 2025) was $136,162 million.1 This is a full-year figure, not specific to Q4 2025, and it represents cash generated from core business operations before accounting for capital expenditures to arrive at free cash flow.

For the fourth quarter of fiscal year 2025 (Q4 2025), Microsoft reported an operating income of $34.3 billion, which represents a 23% increase year-over-year (22% in constant currency).2

To provide a comprehensive comparison, I need to find the actual free cash flow for Microsoft's Q4 2025 and analyst estimates for both Q4 2025 free cash flow and operating income growth. Unfortunately, the provided search results do not explicitly state Microsoft's free cash flow for Q4 2025, nor do they detail specific analyst estimates for Q4 2025 free cash flow or operating income growth for comparison against the reported figures. The available analyst estimates primarily cover EPS, revenue, and EBITDA for various future periods.3

Without specific analyst consensus figures for Q4 2025 free cash flow and operating income growth, a direct comparison is not possible at this moment. However, the reported operating income growth of 23% for Q4 2025 indicates a strong performance in generating profits from core operations.2

For a deeper dive into Microsoft's financial performance, you can explore their official SEC filings on Fintel, particularly the 10-K for fiscal year 2025 when it becomes available, which will contain detailed cash flow statements.
