As of Q1'26 (2025-11-23), Costco's latest reported SG&A Expenses stand at USD 6.33B, while R&D Expenses remain at USD 0. This indicates that the company continues to allocate no spending towards R&D, with operating expenses dominated entirely by SG&A costs. Over the period from Q2'23 to Q1'26, SG&A Expenses have shown a recurring seasonal pattern, peaking in Q4 of each fiscal year (USD 6.94B in Q4'23, USD 7.07B in Q4'24, and USD 7.78B in Q4'25). Despite minor quarter-to-quarter fluctuations, the overall trend demonstrates gradual growth in SG&A Expenses, rising from USD 4.94B in Q2'23 to USD 6.33B in Q1'26. The absence of R&D spending highlights a consistent cost structure focused on selling, general, and administrative activities.
