“Our plan is to return to our members in some form the portion of tariffs that were passed on to them,” he said on an earnings call on Thursday.

Vachris said the company has begun submitting tariff refund forms and expects payments on a rolling basis within the next few months.

“What we return and when depends on a variety of factors, including how much refund money we receive and when it arrives, as well as developments in the lawsuit filed against the company regarding the return process,” he added.

Overall, Costco beat expectations for the three months ending on May 10, with net sales of US$69.15 billion, up more than 11 per cent from a year ago.

The retailer’s gas division was a particular bright spot. It saw “record-breaking volumes” as customers turned to Costco for discounted gas as prices have skyrocketed because of the war in Iran.

“We believe this will drive even greater loyalty with these members in the future, as members who use our gas stations typically spend more with us in the warehouse,” Vachris said.

The popularity of weight loss drugs like Ozempic have benefited Costco’s pharmacy division, where customers can typically receive a discount on expensive drugs.

These drugs have also spurred more high-protein focused diets, and Costco has taken notice.

“Anything protein right now is doing extremely well. Protein bars, protein snacks, beef sticks,” Millerchip said.

“That’s an example of an area where we’re really leaning into those items because of what we’re seeing from our members in the value and quality they’re looking for.”
