Berkshire Hathaway’s new CEO Greg Abel may reconsider buying Costco Wholesale shares after former CEO Warren Buffett sold the entire stake in 2020 and later called the sale a mistake. Costco’s third-quarter fiscal 2026 net sales rose 11.6% to $69.15 billion, with net income of $2.19 billion, while membership renewal rates hit 92.3% in the U.S. and Canada. The company’s July 2026 four-week net sales reached $23.12 billion, up 10.7% year over year, with comparable sales up 8.9% globally. Under Abel, Berkshire has shown more willingness to invest in dominant consumer franchises with recurring cash flows, making Costco a potential fit.
