Here are the S-3 shelf registrations from Costco Wholesale Corporation (COST) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
An S-3 covers the shelf registration that lets an established company sell over time, so if you follow COST and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full COST filings page.
Costco Wholesale Corporation filed a shelf registration statement on Form S-3 to register debt securities for one or more future offerings under a prospectus dated June 3, 2026. The prospectus describes general terms for unsecured senior debt to be issued under existing indentures dated October 26, 2001 and the First Supplemental Indenture dated March 20, 2002, and states that specific terms, offering sizes, proceeds treatment and distribution methods will be provided in prospectus supplements.
The prospectus says net proceeds will be used for general corporate purposes unless a supplement specifies otherwise, and it outlines mechanics for global book-entry registration, transfer agents, trustee protections, Events of Default, modification thresholds and governing law (New York). The filing incorporates by reference financial statements through the fiscal year ended August 31, 2025 and names KPMG LLP as auditors.
