Sept 24 (Reuters) – Costco Wholesale beat quarterly estimates on Thursday, recording strong comparable sales growth as inflationary pressures drove consumers to ​its discount gas stations and boosted demand across its ‌warehouses.

The warehouse retailer reported fourth-quarter adjusted earnings per share of $6.60, excluding a one-time 15-cent benefit from tariff refunds, beating analysts’ estimates of $6.53, according to LSEG data.

Quarterly revenue rose about 11% from a year earlier to $95.72 billion, topping Wall ‌Street ​estimates of $94.86 billion. Total same-store sales excluding ⁠gas and foreign exchange ⁠effects rose 6.7%, above analysts’ expectations of 6.11%.

Costco has benefited as consumers look to stretch household budgets, with its low-price bulk model and discounted fuel offering helping attract shoppers amid persistent ​cost pressures.

“It was another well-rounded quarter for Costco, with comparable sales growth continuing to lead its big-box peers, driven by ⁠balanced traffic and average ticket growth,” ⁠CFRA analyst Arun Sundaram said.

Gasoline was a key sales ​driver, with CEO Ron Vachris saying the business had a “record year.”

Costco ​gas stations, which usually sell below market value, according ‌to TD Cowen analyst Oliver Chen, have helped pull in price-sensitive customers as the Iran war sends fuel prices soaring.

The company received tariff refunds of $184 million during the quarter under the International Emergency ⁠Economic Powers Act, Costco’s CFO Gary Millerchip said in a post-earnings call.

The refunds were reinvested through price reductions on some items, including essentials, ⁠meat, beverages and ‌some non-food items, CEO Ron Vachris added.

The retailer ⁠has also seen average basket sizes increase as ​shoppers ‌consolidate their trips to the store, loading up ​on groceries ⁠and other essentials in one visit rather than doing multiple runs.

The company’s shares were flat in extended trading. As of Thursday’s close, the stock has risen nearly 4% so far this year.
