In Q4'26, Walmart's operating cash flow reached $14.11B USD, marking a robust increase from the prior quarter and reflecting strong year-end performance driven by seasonal sales. Free cash flow for the same period stood at $6.14B USD, indicating positive liquidity after capital expenditures, though it remains below the operating figure due to ongoing investments. Over the period from Q1'24 to Q4'26, operating cash flow exhibited volatility with peaks in Q2'24 ($13.57B USD) and Q4'24 ($16.71B USD), alongside dips in Q3'24 ($0.81B USD) and Q1'25 ($4.25B USD), but showed an overall upward trend averaging around $10B USD quarterly, underscoring improving operational efficiency. Free cash flow displayed greater fluctuations, including negative values in Q3'24 (-$4.62B USD) and Q1'25 (-$0.36B USD), yet trended positively in recent quarters with consistent gains in Q2 and Q4 periods, highlighting Walmart's ability to generate surplus cash despite capital-intensive retail operations.
