It was reported on September 25 that Costco Wholesale Corporation (NASDAQ:COST) maintains solid underlying business momentum following its Q4 and fiscal year 2026 results, according to a recent research note from RBC Capital. The firm reaffirmed its Sector Perform rating and $1,000 price target, while boosting its EPS forecasts by $0.21 to $20.76 for FY26 and by $0.10 to $22.86 for FY27.
RBC’s upward revision incorporates expected IEEPA tariff refunds in early 2027 alongside updated margin, store expansion, and capex assumptions. For investors, the analyst’s takeaway is clear: while operational stability is intact, the stock’s stretched valuation multiple remains its primary hurdle.

Bull Case: High-Margin Recurring Fees and Robust Cash Generation
Costco Wholesale Corporation’s earnings foundation remains structurally protected by its high-margin membership revenue. In FY26, total revenue reached $303.15 billion, powered by $5.91 billion in recurring membership fees, an 11% increase year-over-year. This recurring revenue stream shields net profitability ($9.23 billion in FY26) from retail price swings and fuels aggressive reinvestment into customer value.
Additionally, Costco’s cash generation provides exceptional financial flexibility. Operating cash flow rose to $15.83 billion in FY26, up from $13.34 billion, allowing the warehouse retailer to fully fund $6.44 billion in capital expenditures for store footprint and digital capabilities. Cash and cash equivalents surged to $20.21 billion (up from $14.16 billion), strengthening balance-sheet health while non-current debt declined from $5.71 billion to $3.91 billion. Supported by 19.5% e-commerce growth in Q4 and a pipeline of 939 global warehouses, Costco demonstrates durable avenues for long-term expansion.
Bear Case: Valuation Constraints and Gross Margin Pressures
Despite operational momentum, the central bear thesis hinges on valuation risk. RBC explicitly identified the stock’s premium multiple as its core bottleneck. Trading near ~40x–45x forward earnings, Costco leaves little safety margin if macroeconomic conditions soften or if comparable sales moderate from Q4’s 9.4% pace (6.7% adjusted).
Operationally, maintaining low prices exposes merchandise margins to category shifts and cost inflation. Furthermore, Q4 net income ($2.998 billion) included a non-recurring $0.15 EPS bump from tariff refunds, masking underlying margin pressures. With warehouse capacity constraints demanding heavy capital spending ($6.44 billion in FY26) and delivery execution tied to third-party providers, earnings growth will remain heavily reliant on high sales volume to offset limited operating leverage.

Conclusion
RBC’s update frames Costco Wholesale Corporation as a fundamentally elite business navigating a demanding equity valuation. Strong cash flows, $5.91 billion in recurring membership fees, and balance-sheet deleveraging reaffirm its competitive moat. However, with an elevated earnings multiple and ongoing margin reinvestments, upside from current levels requires seamless operational execution across its global expansion.
