COST · Q3 2025 Earnings

The dominant tone shift this quarter is from a company that talks about inflation in quarters to one that talks about tariffs in hours. Ron's phrasing in Q&A — "we're watching pricing daily and if not hourly on every key commodity" — reframes Costco's planning cadence. Prior commentary had treated cost pressure as a quarterly variable to be managed through buying expertise; this quarter, management explicitly described a tactical, item-by-item process of deciding what to absorb and what to pass through. The signal: margin trajectory is no longer self-directed.

The LIFO commentary is the most concrete tone reversal. Earlier in the fiscal year, deflation in non-foods was producing a LIFO credit. This quarter Gary disclosed a $130M Q3 LIFO charge and a ~$145M full-year point estimate, with an additional $40–50M expected in Q4. The shift from LIFO credit to inflation charge has happened inside two quarters, and management's explicit conditional — "if the current rate of inflation is maintained" — concedes they have low visibility on where it stabilizes.

Management also softened its previously unqualified confidence on holding prices. Gary's prepared-remarks framing that "raising prices is always seen as a last resort" was paired in the Q&A with Ron's acknowledgment that the team is rerouting goods, pulling forward summer inventory ahead of tariff impacts, and accepting that on some items they had to "come just slightly up on prices when we needed to be." That tactical disclosure tells you the discussion is happening internally with more urgency than the headline comp would suggest.

Non-foods growth was discussed with newly tempered language: "we were up double digits in non-foods and we were high single digits this quarter." Gary attributed the deceleration partly to cycling bullion and gift card strength. The honest acknowledgment that some prior-quarter strength was non-recurring is a departure from Costco's typical reluctance to attribute comp strength to specific catalysts.

Finally, management was unusually explicit that margin cadence is not the lens. Asked by Scott Ciccarelli about the multi-quarter streak of EBIT margin expansion, Gary said the team is "probably less focused than you might think on the individual quarters" and instead manages for the long term. Separately, asked by Zihan Ma whether the Q3 LIFO dynamic bleeds into FY26, Gary said "it really depends on what happens with inflation going forward" — i.e., next-year LIFO is contingent on the tariff path, not carryover. Costco does not normally hedge either point. The hedge is the news.
