Costco's exclusive hours for executive members ‘very well received,' drive sales boost of 1%

Costco reported robust Q4 net sales up 8% to $84.4 billion and FY sales climbing 8.1% to $269.9 billion, significantly bolstered by its new exclusive morning hours for executive members, which added an estimated 1% to weekly US sales and drove upgrades. The company expanded its global warehouse count to 914 with plans for 35 more in FY2026, while growing its paid membership to 81 million (+6.3% YoY), maintaining strong renewal rates despite a minor dip attributed to specific online sign-up cohorts. This performance highlights effective member engagement strategies and continued expansion opportunities.

Analysis

Costco Wholesale (COST) reported robust financial results for its fourth quarter and fiscal year 2025, underscored by strong top-line growth and effective member engagement strategies. Quarterly net sales increased 8.0% year-over-year to $84.4 billion, while full-year sales climbed 8.1% to $269.9 billion. A key contributor to this performance was a strategic initiative offering exclusive store hours for executive members, which management estimates added approximately 1% to weekly U.S. sales and stimulated a "meaningful increase" in membership upgrades. The company's member base expanded by 6.3% to 81 million paid members, with renewal rates remaining exceptionally high at 92.3% in the U.S. and Canada. While the global renewal rate dipped slightly to 89.8%, this was attributed to a higher volume of online sign-ups from a specific Groupon campaign entering the renewal pool, not a deterioration in core member loyalty. Looking forward, Costco provided strong growth guidance, planning to open 35 new warehouses in fiscal 2026 after adding a net 24 in fiscal 2025, signaling confidence in sustained domestic and international expansion opportunities.

Key Decisions for Investors

• The strong sales growth, driven by successful member-centric initiatives like exclusive hours, reinforces the company's robust fundamentals and supports a continued positive outlook on the core business.
• Investors should monitor the execution of the aggressive warehouse expansion plan for fiscal 2026, as the company's ability to successfully open 35 new locations will be a key driver of future revenue growth and market share gains.
• While the dip in global renewal rates was explained, this metric remains a critical leading indicator of customer loyalty and pricing power, and should be watched in subsequent quarters to confirm it was a temporary anomaly.
• Costco's demonstrated ability to enhance its value proposition and manage operational challenges, such as mitigating tariff impacts, strengthens its competitive moat and resilience in the retail sector.
