As of Q1'26 (2025-11-23), Costco's latest Operating ROA stands at 2.42%, with ROE at 6.60% and ROIC at 4.66%. These figures indicate a slight decrease from the previous quarter, reflecting a modest contraction in profitability metrics at the start of fiscal 2026. Over the period from Q2'23 to Q1'26, the chart shows that all three profitability ratios—ROA, ROE, and ROIC—have experienced moderate fluctuations, with notable peaks in Q4'24 and Q4'25. Despite some short-term volatility, the overall trend remains relatively stable, with no sustained upward or downward momentum. The data suggests that Costco has maintained consistent operational efficiency and capital returns, though periodic quarter-to-quarter variations are evident.
