BJ vs COST: Weighing Expansion Momentum Against Mature Stability
Key Takeaways
- Scale contrast: COST operates roughly 939 warehouses globally, while BJ runs 267 clubs concentrated in the Eastern United States.
- Growth profile: BJ is in an expansion phase with a new Texas market and double-digit comparable sales, whereas Costco's growth is steadier and more mature.
- Valuation gap: Costco trades at a premium forward price-to-earnings (P/E) multiple, while BJ carries a lower valuation with a smaller market capitalization.
- Membership momentum: BJ is adding members rapidly off a smaller base, while Costco's membership growth has moderated in recent quarters.
- Margin trade-off: Both retailers are reinvesting tariff refunds into lower prices, pressuring near-term merchandise margins.
Why Compare These Two Warehouse Clubs
BJ and COST follow the same membership-based model yet sit at very different points in their development. This matters for investors deciding between a regional operator still building scale and a global leader with decades of execution behind it. In my view, the contrast highlights different risk-reward profiles that depend on whether one prioritizes faster near-term growth or long-term stability.
BJ's Position and Recent Results
BJ (BJ's Wholesale Club Holdings, Inc.) runs 267 clubs and 206 gas stations, mainly across 22 Eastern states. Its latest quarter showed net sales rising about 15.9% to roughly $6.09 billion and total comparable club sales up 11.9%. Excluding gasoline, comps increased 3.1%, marking the 18th straight quarter of traffic growth and the 15th of market-share gains. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Membership fee income grew around 9.9%, pushing total members to a record 8.5 million. Digitally enabled sales rose about 30%. Management lifted its full-year adjusted EPS guidance. Early results from the Texas expansion have exceeded internal plans, though investments in pricing and new clubs have weighed on merchandise margins.
Costco's Position and Recent Results
COST (Costco Wholesale Corporation) is the largest player in the space, with 939 warehouses spanning the U.S. and more than a dozen other countries. Net sales climbed about 11.2% to $93.87 billion in the most recent quarter, while total comparable sales rose 9.4%. Adjusted comps, stripping out gasoline and currency effects, advanced 6.7%.
The company finished the year with roughly 84.1 million paid members, up 3.8% year over year, and posted a 92.3% renewal rate in the U.S. and Canada. Membership fee income increased 7.3%. Digitally enabled sales grew about 19.5%. A one-time tariff refund benefit was largely reinvested into lower prices. From what I see, slower membership growth and the stock's premium valuation have left some analysts cautious.
Head-to-Head: Scale, Valuation, and Risks
The clearest differences appear in size and growth stage. Costco's roughly $400 billion market capitalization and worldwide presence provide diversification that BJ, still focused on one region, does not yet offer. On the other side, BJ's double-digit comparable sales and new-market rollout point to a steeper growth curve that a mature operator like Costco is unlikely to match.
Valuation reflects these differences. Costco's forward P/E sits notably higher than BJ's, signaling expectations of continued premium performance. BJ trades at a discount that accounts for its smaller footprint and thinner margins during the expansion phase. Both companies face near-term margin pressure from reinvesting tariff refunds into member pricing, yet that same approach supports traffic and loyalty.
