Memory Inflation Is Hitting Costco's Electronics Business, and It Triggered a $152 Million Charge

Costco reported Q4 EPS of $6.75, beating the $6.52 consensus, on revenue of $95.72 billion versus $94.86 billion expected; shares rose 2.46% to $918.53. Comparable sales increased 9.4%, or 6.7% excluding FX and gasoline, with U.S. comps up 10.7% (7.2% adjusted), while expense leverage supported an EPS beat despite slightly softer gross margin. Analysts largely retained their ratings but trimmed several price targets, citing valuation pressure and a $152 million LIFO charge driven by higher memory and oil-related costs.

Analysis

The key tension is that Costco is converting unusually strong traffic into operating leverage, but the market is unlikely to grant further multiple expansion without evidence that merchandise inflation can be passed through without eroding its price-value proposition. The higher inventory-cost charge is a near-term gross-margin headwind rather than a demand problem; however, persistent memory and oil-linked inflation would force a choice between absorbing costs and protecting membership renewal economics. That makes the next two monthly sales releases and holiday electronics mix more important than the headline EPS beat.

Delivery partnerships are strategically positive only if they broaden household penetration without diverting profitable warehouse trips into lower-margin fulfillment. Incremental orders would favor DASH and UBER, but the larger second-order risk is that third-party delivery increases price transparency and reduces Costco's ability to monetize the in-warehouse impulse basket. CART is comparatively more exposed if Costco meaningfully steers member demand toward competing delivery channels, though the financial impact cannot be established without order-volume and take-rate disclosure.

The near-term setup is not an attractive momentum chase after the post-results move: analyst targets moving lower despite upward earnings revisions signals that valuation, not estimates, is the binding constraint. Over 1-3 months, sustained transaction growth and stable renewal rates can support the shares; over 6-18 months, the upside case requires new-unit productivity and membership monetization to offset a likely normalization in expense leverage. A reversal would be signaled by a deceleration in traffic-led comparable sales, a material gross-margin miss excluding fuel/mix effects, or a decline in renewal/member growth.

Contrarian view: Costco's resilience may be more defensible than discretionary retail, but that does not make it immune to a consumer trade-down becoming less favorable to its higher-ticket general-merchandise categories. If tariff-related consumer cash is temporary, the market may be pulling forward a demand benefit that should not be capitalized into a durable earnings multiple. Walmart is the cleaner relative beneficiary if value-seeking demand broadens beyond Costco's membership base.

Key Decisions for Investors

• Do not add directional COST exposure into strength; initiate only on a pullback or after the next monthly sales release confirms traffic durability. Use a 1-3 month horizon, with a gross-margin miss excluding fuel/mix or slowing membership growth as thesis invalidation.
• Express relative defensiveness via long WMT / short COST for 3-6 months if COST continues to outperform while valuation remains the constraint. The trade benefits if broad value retail demand holds but Costco's multiple compresses; cover if Costco reaccelerates membership growth and margin expansion simultaneously.
• Maintain DASH and UBER on a 6-12 month partnership-monitor list rather than buying solely on the announcement. Upgrade to a position only if either company discloses Costco-driven order growth or improving contribution margins; otherwise, economics may be immaterial relative to their existing delivery bases.
• Watch CART for competitive displacement risk over the next two quarters. A short is not yet warranted without evidence of lost retailer volume, but declining gross transaction value growth or incremental marketing spend would validate a hedge against the delivery-partnership theme.
