Costco’s Q3 FY2025 outcomes reaffirm its standing as a uniquely disciplined and predictable retail compounder. With a decade-long income CAGR of 9%, decomposed into 2.64% retailer development and 6.13% comparable gross sales development, the corporate continues to execute on its “12/9/3” margin mannequin—anchored in capped gross margins and low opex to ship relentless worth to members.
