Costco Under Pressure: Downgrade and BJ’s Gain Now

Introduction

This week delivered several concrete developments that could affect Costco Wholesale Corporation (NASDAQ: COST). A high-profile analyst downgrade, accelerated expansion by a key rival, and tariff-driven product changes combined to create a more challenging operating backdrop. For investors focused on COST, these are not abstract trends but specific events with identifiable implications for revenue, margins, and investor sentiment.

Key Events That Moved the Needle

Roth Capital downgrades Costco

Roth Capital cut its rating on Costco and lowered the price target from $906 to $769, citing slowing membership renewal and softer new-member trends. The market reacted: COST shares slipped roughly 2.7% following the note and are down about 6% year-to-date. The downgrade highlights investor sensitivity to membership metrics — Costco’s primary recurring-revenue engine — and signals that even best-in-class retailers can face valuation pressure when subscription-related growth shows signs of deceleration.

BJ’s Wholesale Club ramps expansion, targeting Texas

BJ’s announced plans to open as many as 30 new clubs over the next two fiscal years, with a notable push into North Texas through multiple site projects and fuel-station builds. That aggressive growth path represents a tangible competitive threat in markets where Costco already competes for household wallet share. New Club openings and fueling amenities are designed to win members and increase visit frequency — exactly the levers that support membership retention and ancillary sales.

Tariff pressure and merchandise adjustments

Costco is reshuffling seasonal and discretionary assortments in response to tariff-driven cost increases. The company pared back some niche imported holiday SKUs (artificial trees, certain toys and decorations) — roughly a small percentage of total SKUs — and emphasized domestically sourced alternatives in categories like food and HBA (health and beauty aids). Management is absorbing some costs, consolidating shipments, and pursuing refunds where appropriate. Those moves aim to protect member value but can compress gross margins in the near term.

Why These Developments Matter to Investors

Membership revenue remains the backbone

Membership fees are the core of Costco’s profitability. Recent reporting reiterated that membership income exceeds $5 billion annually against more than $270 billion in net sales, with U.S. renewal rates north of 92% and global renewals near 90%. Think of Costco’s memberships like a large-scale subscription business: predictable, high-margin cash flow that cushions merchandise margin volatility. That durability is why the stock hasn’t collapsed despite the headwinds.

Headwinds are specific and actionable

The combination of a downgrade, regional competitor expansion, and tariff-driven assortment changes creates three distinct channels of risk: 1) sentiment and valuation compression from analyst downgrades, 2) localized share loss where BJ’s expands aggressively, and 3) cost pressure from tariffs that could shave margins if managed improperly. Each is measurable and potentially reversible—but they warrant closer monitoring.

Short-term Implications and Things to Watch

• Membership trends: Watch renewal and net-new paid-member figures in Costco’s next earnings release. Any sustained decline would justify the caution reflected in the downgrade.
• Competitive footprint: Track BJ’s new-club openings in markets where Costco is dense. Localized traffic and spending shifts often precede broader share impacts.
• Margin cadence: Monitor gross-margin trajectory and management comments on tariff mitigation strategies — consolidation, sourcing shifts, or partial price pass-through.

Conclusion

This week’s news creates a nuanced picture for COST: the company’s subscription-like membership base still generates reliable, high-margin cash flow, but concrete short-term pressures have emerged. The Roth Capital downgrade reflects heightened sensitivity to membership momentum; BJ’s expansion poses a regional competitive risk; and tariffs force product assortment and margin trade-offs. For investors, the practical response is to watch membership metrics, local competitive moves, and management’s margin actions. Those data points will determine whether these developments are temporary friction or the start of a longer-term trend.

Analysts and shareholders should expect Costco to defend its renewal franchise through operational and membership-focused tactics — a strategy that has historically preserved value but now faces renewed tests from competitors and macro cost pressures.
