Costco shares have retreated nearly 20% from their early-2025 peak, underperforming many of its higher-multiple retail peers despite continued revenue growth. Full-year net sales rose 8.3% year-over-year to $327 billion, while same-store sales in the most recent quarter grew 5.7%. Yet the stock trades at roughly 46.7 times trailing earnings, a substantial premium to the 39.1 multiple of its largest traditional competitor. Investors have grown cautious as valuation concerns outweigh the company’s steady top-line momentum, and there is no clearly identified catalyst to reverse the downtrend in the near term.

With the share price flirting with four figures, management faces mounting pressure to consider a 10-for-1 split in calendar 2026 to improve accessibility for smaller investors. At approximately $867 per share today, the cost of acquiring a single board lot remains prohibitive for those without access to fractional-share programs. Historically, Costco has raised membership fees every few years, but has not split its stock since 2014. A split could broaden the retail base and generate renewed trading interest, although the availability of fractional shares may reduce the urgency of such a move.

Costco continues to invest in new warehouses and digital initiatives to sustain long-term growth. The firm opened 27 new clubs in fiscal 2025, pushing its global count past 900 locations, with international openings focused on high-growth Asian markets. E-commerce sales grew at a double-digit pace last year, supported by enhanced online inventory transparency and expanded last-mile delivery partnerships. Additionally, the company is piloting warehouse automation technologies aimed at reducing fulfillment times and labor costs. Membership renewals remain robust, with paid households rising to 81 million and renewal rates holding near 90%, underpinning recurring high-margin fee income.
