In Q2'26, COST's operating expenses totaled $6.27B USD, entirely attributed to SG&A expenses at $6.27B USD, as R&D expenses remained at no data across all periods. This latest figure reflects a slight quarterly decline from $6.33B USD in Q1'26. Over the period from Q3'23 to Q2'26, SG&A expenses—the sole contributor to operating expenses—exhibited volatility with a general upward trend, peaking at $7.78B USD in Q4'25 before moderating. Notable surges occurred in Q4'23 ($6.94B USD) and Q4'24 ($7.07B USD), indicating seasonal or operational expansions, while R&D consistently showed no data, suggesting minimal investment in this category for COST.
