Costco September Comparable Sales Rise 11.4%, Beating 9.9% Estimate

Costco's September beat lands on both the headline and the cleaner US ex-gasoline and FX measure, suggesting the upside is broad-based rather than a fuel-price or currency artifact. For a membership retailer whose model depends on steady traffic and renewal, that kind of comparable-sales strength is a read on consumer resilience at the value end of retail. The open question is whether this pace persists into the next reporting period or reflects a one-month pull-forward.
