Expert Insights

From a fundamental perspective, Costco’s sustained 90%+ North American membership renewal rate is one of the widest defensive moats in the global retail sector, as recurring membership fees contribute roughly 70% of the firm’s operating profit and lock in customer loyalty before any in-store or online transactions occur. The current gap in renewal rates between digital and in-person sign-ups is a predictable growing pain associated with the firm’s omnichannel expansion, rather than a sign of eroding brand value: targeted retention campaigns and value messaging tailored to digital-first cohorts are likely to lift renewal rates to match in-person levels over the next 12 to 18 months, in line with early performance signals from current initiatives. While Walmart and BJ’s are accelerating their own omnichannel capabilities, neither competitor has been able to replicate Costco’s membership loyalty dynamic: Walmart’s e-commerce growth is driven largely by transactional convenience rather than recurring membership lock-in, while BJ’s higher digital growth rate is coming off a far smaller user base, limiting its competitive threat to Costco’s core middle-to-upper income customer base. Costco’s valuation premium relative to the broader retail sector is justified by its low-volatility, defensive revenue profile, which outperforms traditional retail peers during periods of macroeconomic slowdown as consumers prioritize bulk value purchases. The 10% projected EPS growth for fiscal 2027 is consistent with the firm’s long-term growth trajectory, making it an attractive holding for risk-averse investors seeking stable returns in an uncertain market environment. That said, the stock’s trailing 12-month underperformance relative to the sector reflects limited near-term upside catalysts, as investors have already priced in most of the benefits of the firm’s omnichannel expansion. The Zacks #3 (Hold) rating is appropriate for the stock at current levels: existing investors can maintain positions to capture long-term recurring revenue growth, while new investors may want to wait for a modest valuation pullback to enter at a more attractive entry point.
