What Management Said

Here are the key debates and direct quotes from Costco's Q3 2025 earnings call:

Balance Between Tech/Digital Investment and Preserving the Low‑Price Model (Including Retail Media & AI)

Sentiment: Positive

"We feel that technology is going to be part of the peak part of our future... But we will never succumb to not being the best price and driving prices down for our members. That's what Costco is known for. That will always be our leading mantra." — Ron Vachris
"Bit like Ron mentioned earlier... all of our focus is on how to drive more value for the member. So as you might expect, the vast majority of the value create here will reinvest in the member to drive down prices and value and and increase sales." — Gary Millerchip

Membership Health, Renewal Rate Pressure from Digital Sign‑Ups, and Executive Member Strategy

Sentiment: Positive

"This slight decline was due to the factors we discussed last quarter and reflects new online members growing as a percentage of our total base renewing at a slightly lower rate than warehouse sign-ups... although... we may still see a slight decline in the overall renewal rate over the next few quarters." — Gary Millerchip
"Our membership team is really focused on delivering targeted relevant messaging to engage those members... and what you saw in this quarter was that really some of the early work the team's done to engage those members and improve the renewal rate." — Gary Millerchip

Real Estate Strategy: Long‑Term Warehouse Growth, Infill vs. New Markets, and Relocations/Remodels

Sentiment: Positive

"I like I said in the early opening remarks, good runway for 30 plus locations as we look forward for the next few years for sure... And international still presents some very good strengths for us... we feel really strong about our future expansion." — Ron Vachris
"We tend to look five to ten years out in terms of our real estate plans and we would still see a really good roadmap for 30 plus warehouses a year... around half, maybe slightly over half to be in The US and then just around half to slightly under a half to be in the rest of the markets that we operate in." — Gary Millerchip

SG&A Leverage, Wage/Health-Care Headwinds, and Productivity from Tech

Sentiment: Mixed

"Our operators did a great job improving productivity and capturing efficiency benefits from the technology investments that Ron referenced earlier... and would have created positive leverage in the quarter had we not experienced higher healthcare costs." — Gary Millerchip
"If we'd have not had the sort of sales and use tax charge that we had during the quarter, and without the health care costs, we'd have been sort of a mid single digit or so positive leverage during the quarter." — Gary Millerchip

Nonfoods and General Merchandise: Deceleration, Gold/Gift Card Laps, and Market Share

Sentiment: Positive

"We have seen a deceleration in nonfoods... really is starting to cycle the impact of gold being sold in warehouse and online and also of the gift card programs that we had last year." — Gary Millerchip
"Overall, we still see good market market share gains in in really pretty much all of the non food categories... golden jewelry, special events, health and beauty were all double digits... majors, in tires, and small appliances... high single digit growth." — Gary Millerchip

Bull Case

Costco’s disciplined expansion, accelerating digital and AI capabilities, and robust membership economics support mid-single-digit comps with rising alternative profit streams that can be reinvested to sustain traffic, share gains, and high returns on capital.

Bear Case

Rising healthcare and wage costs, softening renewal rates from digital cohorts, and decelerating nonfoods growth could cap SG&A leverage and earnings upside just as warehouse and membership growth begin to mature in core markets.

Looking Ahead
