After touching $1,000 per share in December 2024, some are expecting the retail giant to announce a stock split in 2025 (NASDAQ, Investopedia). Costco's fiscal year ends in late August or early September each calendar year, and its quarterly earnings announcements historically have been released in March, May, September, and December. The last split announced by Costco took place in January 2000 (Costco - Split History). The date the split will take effect is immaterial. Confused? Check our FAQ or ask us for help.
