Costco Stock: A Discounted Compounder?

Costco is positioned for significant growth over the next twelve months, with a price target of $1,011.88 suggesting 12.13% upside. The company's fiscal Q3 2026 performance was robust, reporting earnings per share of $4.93 on revenue of $70.53 billion, an 11.58% year-over-year increase. Membership fees rose by 10.7%, maintaining a worldwide renewal rate of 89.7% and showing benefits from pharmacy market share gains tied to GLP-1 medications.

Executive memberships have surged by 9.6% to 41.2 million, now accounting for 75% of net sales. Digitally-enabled comparable sales climbed 21.5% with substantial increases in site traffic and AI-generated search referrals. Costco aims to expand its warehouse count to 940 by fiscal year-end.

While the stock's forward price-to-earnings ratio suggests limited room for growth deceleration, management's strategic pricing initiatives aim to protect long-term pricing authority. Compared to Walmart and BJ's Wholesale Club, Costco's premium valuation is justified by its strong membership renewal rates, scale, and consistent double-digit growth trajectory.
