Costco makes progress on a key membership metric. Here's our new price target on the stock

Costco reported fiscal Q4 revenue of $95.72 billion, up 11.1% year over year and above the $94.86 billion consensus, while adjusted EPS rose 15% to $6.75 and beat expectations even excluding a $0.15 tariff-refund benefit. Comparable sales increased 9.4% versus 9.0% expected, supported by 3.3% traffic growth and 5.9% ticket growth, while digitally enabled comps rose 19.5%. However, paid memberships grew only 3.8% to 84.1 million and missed expectations, extending a slowdown in member growth; the firm retained its hold-equivalent rating and cut its price target to $1,050 from $1,100. Renewal rates improved modestly to 89.8% globally and 92.3% in the U.S./Canada, while Costco plans $7.5 billion of FY2027 capex to support roughly 28 new warehouse openings.

Analysis

COST’s central issue is no longer demand resilience but incremental member economics: slowing net paid-member additions reduce the embedded annuity-growth rate that has historically justified its premium multiple. A modest renewal improvement is directionally positive, but it does not establish that digitally acquired younger cohorts will converge to store-acquired members on churn, basket, or executive-tier conversion. The near-term earnings beat is therefore unlikely to drive durable multiple re-expansion without two consecutive quarters of accelerating paid-member growth and stable renewal rates.

Higher fuel-driven traffic is a mixed-quality catalyst. It supports visits and impulse warehouse conversion in the next 1-3 months, but it also flatters reported ticket growth while providing limited direct gross-profit contribution; normalization in gasoline prices could expose softer underlying ticket and transaction momentum. The larger FY27 development is capex intensity: accelerating openings can preserve top-line growth, but it creates a free-cash-flow conversion headwind until new units mature. This favors operators with more asset-light digital fulfillment economics, notably AMZN, if Costco’s e-commerce traffic gains do not translate into materially higher online mix or incremental merchandise margin.

Competitive read-through is most favorable for BJ, whose smaller footprint leaves more whitespace for club-format expansion and whose valuation should be less dependent on a flawless membership-growth narrative. WMT remains the broader affordability share gainer, but its membership/advertising ecosystem makes it less directly comparable; a consumer trade-down environment can support both WMT and COST rather than produce immediate share transfer. Consensus may be too focused on renewal-rate basis points and too little on acquisition-channel quality, executive penetration, and new-store member productivity—the three variables that determine whether COST can sustain its historical valuation premium over the next 6-18 months.

The contrarian view is that the stock’s de-rating has already discounted a deceleration that is normal for a mature membership base, while inflation-sensitive households may remain unusually sticky. That bull case requires evidence that lower-spend younger members increase frequency and migrate to executive status within 12-24 months; absent this, higher capex and slower fee-income growth argue for a valuation ceiling despite solid operating execution.

Key Decisions for Investors

• Maintain COST as a watch/hold rather than add aggressively after the report. Add only if the next quarter shows paid-member growth re-accelerating above 4% and renewal rates holding or improving; reduce if paid-member growth falls below 3% or merchandise-margin ex-fuel deteriorates. The relevant horizon is 1-2 earnings cycles, not the immediate reaction.
• Initiate a 3-6 month relative-value pair: long BJ / short COST, sized beta-neutral. BJ offers greater unit-growth whitespace and less premium-multiple exposure; target 10-15% relative outperformance, with a stop if COST demonstrates two quarters of accelerating memberships plus executive-tier penetration expansion.
• For broad defensiveness, favor WMT over COST for the next 6-12 months. WMT has more earnings levers beyond merchandise margins and membership fees; use a COST/WMT relative stop if COST’s membership fee income growth re-accelerates materially while WMT’s discretionary general-merchandise trends weaken.
• Monitor COST’s FY27 capex-to-operating-cash-flow ratio and new-warehouse productivity. A rising ratio without accelerating membership additions is the key free-cash-flow and multiple-compression risk; defer any long-duration bullish options structure until management demonstrates that new-market stores are producing superior member acquisition economics.
