Summary
Costco filed its routine quarterly earnings 8-K on May 28, 2026, announcing third quarter fiscal 2026 operating results for the twelve weeks ended May 10, 2026. The filing follows the company's standard practice of attaching financial results as press release and supplemental exhibits rather than embedding detailed metrics in the 8-K body text. Retail investors should review the attached press release (Exhibit 99.1) and supplemental information (Exhibit 99.2) for actual revenue, comparable sales, membership trends, and margin performance.
These exhibits contain the substantive financial data needed to assess Costco's quarterly performance. Watch for management commentary on comparable store sales trends, membership fee income, and any guidance updates in the full earnings materials.
