Shares of Costco Wholesale (NASDAQ: COST) were moving lower today after the warehouse retail giant issued a disappointing March sales report.
Costco said net sales in the five weeks ended April 2 rose just 0.5% to $21.71 billion. Comparable sales, adjusting for fuel prices and currency exchange, were up 2.6% and rose just 0.9% in the U.S., indicating that rising interest rates and a weakening economy finally seem to be impacting Costco, one of the most resilient U.S. retailers. Without adjustments, comparable sales were down 1.1% globally, or 1.5% in the U.S.
As of 10:22 a.m. ET, the stock was down 3.6%.
The monthly sales report showed the company's slowest U.S. comparable sales growth since April 2020, the beginning of the pandemic.
Costco also reported that sales from e-commerce, adjusted for fuel prices and currency exchange, were down 11.6%. Since e-commerce is a key growth area for the company, that also signaled trouble for the company.
Considering the impact of inflation, the results seem to indicate that volume sales fell at the retailer, which could be due to consumer spending shifting to services like travel and restaurants or consumers avoiding big-ticket purchases due to high inflation and the threat of a recession.
One monthly sales report isn't a reason for investors to change their thesis on Costco, but it could signal trouble ahead for the stock, especially as shares are expensive, trading at a price-to-earnings ratio of 35.
The good news for investors is that most of the company's profits come from its membership income, which should be more stable in the current economy, but investors should expect a decline in operating margin based on the weak comparable sales.

Four leading AI models discuss this article
"Weak March comps and expensive valuation together raise downside risk to margins even if membership fees cushion EPS."
Costco's 0.5% net sales growth and 0.9% U.S. comps mark the weakest print since April 2020, with e-commerce down 11.6% adjusted. At 35x P/E this leaves little room for volume erosion if consumers shift to services or delay big-ticket buys amid higher rates. Membership income offers some earnings stability, yet operating margins are still likely to compress on lower throughput. The report does not yet prove a sustained downturn, but it removes the 'recession-proof' premium that has supported the multiple. Investors should watch Q3 traffic and renewal rates for confirmation.
The slowdown could prove transitory as post-pandemic e-commerce normalizes and fuel/currency adjustments mask underlying resilience; one month rarely shifts Costco's long-term membership-driven economics.
"One weak month in a resilient business at a stretched valuation warrants caution but not conviction until Q3 earnings confirm whether this is noise or signal."
The article conflates a single month's weakness with a structural problem. Yes, 0.9% U.S. comp growth is soft, but Costco's membership model insulates 40%+ of operating income from sales volatility—that's not mentioned here. The 11.6% e-commerce decline is real and concerning, but context matters: Costco's e-commerce base is still small (~5% of sales) and highly promotional during weak periods. At 35x P/E, the stock prices in perfection, so this miss justifies a 3-4% pullback. But one month doesn't prove demand destruction; we need Q3 earnings (late May) to confirm whether this is cyclical softness or structural.
If consumer spending is genuinely rotating away from goods to services, and if Costco's membership renewal rates slip in the next renewal cycle (typically 60% of members renew annually), the membership income buffer evaporates faster than the article suggests.
"Costco's 35x earnings multiple is unsustainable in a high-interest-rate environment where discretionary spending is shifting away from bulk retail toward services."
The 3.6% pullback in COST is a rational reaction to a 35x forward P/E multiple meeting reality. When a premium-valued retailer hits a wall—specifically a 0.9% U.S. comparable sales growth—the 'defensive' narrative fractures. The 11.6% drop in e-commerce is particularly alarming, suggesting Costco is losing its grip on the digital convenience trade. While membership fees provide a floor for earnings, the market is currently pricing in perfection; at these levels, any deceleration in discretionary spending turns the stock into a value trap. Investors should watch for margin compression in the next earnings report as the company likely sacrifices profitability to maintain volume.
The March slowdown could be a temporary calendar anomaly tied to the timing of Easter and SNAP benefit reductions, potentially masking underlying strength in core grocery volume.
"Costco's membership moat and pricing power will cushion near-term weakness, but the stock's valuation could re-rate meaningfully if comps don't stabilize."
Costco's five-week sales barely grew; the print isn't catastrophic, but the setup is fragile. A 0.5% net sales gain, 2.6% in constant-currency comp, and 0.9% U.S. comp show resilience in a high-inflation environment, though inflation is weighing on basket size and big-ticket purchases. The 11.6% drop in adjusted e-commerce could reflect channel shifts (buy-online, pickup in-store) or normalization after a pandemic surge, not a secular collapse. The main cushion remains membership revenue, a typically sticky source of profit. Near term, multiple compression could widen if comps stall, but the Costco moat supports a guardedly constructive longer-term view.
The risk is more structural than the article lets on: if inflation persists and consumer sentiment stays weak, the 0.9% U.S. comp may stall, e-commerce erosion could signal a secular shift away from warehouse clubs, and multiple expansion could compress further as earnings growth slows.
"Soft comps risk accelerating membership churn, amplifying earnings pressure beyond the buffered model."
Claude correctly notes membership fees buffer 40% of operating income, but this assumes stable renewal rates. The 0.9% comps and 11.6% e-commerce drop could accelerate churn if members delay renewals amid high rates and shifting spending. Gemini's value trap warning gains traction here, as any slip in the 60% annual renewal base would compress earnings more than sales volatility alone suggests. Q3 traffic data becomes critical sooner than late May.
"Renewal churn is a real tail risk, but March comps alone don't prove it's happening—we need Q3 renewal data before treating membership income as compromised."
Grok flags renewal churn risk, but we're speculating without data. Costco's renewal cycle runs staggered throughout the year—March comps alone don't signal renewal weakness. The 60% annual renewal rate is historical; we need actual Q3 renewal data before assuming membership income buffer erodes. Conflating one weak comp month with membership deterioration jumps several steps. That said, Grok's point about *timing* matters: if renewal notices hit during consumer retrenchment, churn could accelerate faster than historical patterns suggest.
"At 35x P/E, Costco's valuation is unsustainable if U.S. comps fail to re-accelerate, regardless of membership fee stability."
Gemini’s 'value trap' warning is the most salient risk here. Everyone is obsessing over the membership fee buffer, but at 35x forward P/E, Costco is priced for growth, not just stability. If U.S. comps stall at 0.9%, the earnings yield becomes uncompetitive against risk-free rates. We are ignoring the 'trade-down' effect: if inflation persists, even Costco members may pivot to extreme discounters like Dollar Tree or Walmart’s private-label aggressive pricing strategies.
"The renewal-rate cushion is not a guarantee; if renewal slows, membership revenue declines and margins compress, making the 40% buffer unreliable."
Claude's renewal-rate caveat is prudent, but the math assumes stable renewal. If consumer retrenchment persists, Costco's annual renewal rate could slow, shrinking membership revenue that funds ~40% of operating income. Even with flat unit sales, margins may compress as higher fulfillment/discounting costs press on a weaker throughput. Q3 renewal data is the critical test; until then, treat the 'buffer' as a risk—not a guarantee.
Costco's weak sales growth and e-commerce decline have removed its 'recession-proof' premium, with investors awaiting Q3 traffic and renewal rates for confirmation. The panel is divided on the sustainability of the downturn and the impact on membership renewal rates.
