Costco revenue hit $70.5B, up 11.6%, yet stock flat. The tariff refund decision after a Supreme Court ruling is the real earnings driver.
Alpha Score of 56 reflects moderate overall profile with moderate momentum, moderate value, moderate quality, moderate sentiment.
Costco Wholesale reported fiscal third-quarter net sales of $69.15 billion, up 11.6% year over year, and total revenue of $70.53 billion that topped Wall Street expectations. Shares were largely unchanged in extended trading. The flat after-hours tape tells the market's real focus: the tariff refund decision that will determine margin outcomes for the remainder of the year.
A naive reading of the print calls it a clear win. Net income rose to $2.19 billion, or $4.93 per share, from $1.9 billion, or $4.28 per share, a year earlier. Adjusted comparable sales climbed 6.6%, with digital sales up nearly 21%. The better market read captures why the stock did not move. The earnings beat was already priced into the defensive rotation that has lifted Consumer Staples names. The tariff question introduces enough uncertainty to cap upside until the resolution becomes concrete.
Membership growth of 4.1% and digital traffic up 37% reinforce the baseline demand story. Top categories included pharmacy, home furnishings, and gold and jewelry. Those three categories show that both health spending and discretionary purchasing held during the quarter. Gold and jewelry in particular suggests consumers are hedging economic uncertainty through hard assets. That behavior creates a tailwind for Costco as a safe-haven retailer. The stock's flat reaction is not a rejection of the operational strength. It is a signal that investors are willing to trade upside for clarity on costs.
The Supreme Court decision that invalidated some of President Trump's foreign import levies puts Costco in an unusual position. The company said it would lower prices if it receives tariff refunds. In the near term, refunds reduce cost of goods sold and expand gross margins. The commitment to pass savings to customers means any margin benefit may compress volume-driven gains unless membership growth accelerates further. If refunds are delayed or denied, Costco absorbs the tariff cost, which pressures operating margins directly. This two-path outcome makes the refund decision the most consequential single variable for the stock in the next six months.
Costco currently holds an Alpha Score 57/100, labeled Moderate, within the Consumer Staples sector. That score reflects neutral momentum and moderate valuation risk. The score does not flag a directional signal. It suggests that the risk-reward is balanced until the tariff refund decision is confirmed.

The immediate catalyst is Costco's full earnings call and any concrete update on tariff refund timing. If management signals near-term refund resolution, the stock could reprice margins higher. If the company remains vague, uncertainty keeps a lid on valuation. The 4.1% membership growth and 37% digital traffic surge are strong operational signals. The market is waiting for the one variable that can shift the margin story either way.
