Costco (NASDAQ: COST) declared a $30-per-share special cash dividend on November 10, 2026, with an estimated total payment of $13.3 billion. The dividend is payable on December 4, 2026, to common shareholders of record at the close of business on November 24. Its Form 8-K and accompanying release set out the terms.
The board also reauthorized up to $4 billion of common-stock repurchases through November 2030. This replaces a $4 billion program adopted in 2023 that was scheduled to expire in January 2027. Costco said $3.1 billion had already been purchased under that earlier program.
Subtracting reported purchases from the old ceiling leaves roughly $0.9 billion of unused authorization. On those rounded figures, the replacement increases available repurchase capacity by approximately $3.1 billion, rather than adding $4 billion to the unused balance. Authorization does not mean the purchases have occurred.
The release does not specify a funding plan for the special dividend or a timetable for using the repurchase authorization. It establishes a distribution date and a buyback ceiling, rather than a combined cash-spending forecast.
