Costco’s Q4 2026 earnings release, scheduled for September 24 after market close, centers trader attention on whether management will highlight sustained comparable sales momentum, membership fee gains, and digitally enabled growth. August net sales rose 9.9% year-over-year to $23.7 billion, while the 16-week quarter showed 11.3% growth; Q3 results featured 9.8% comps (6.6% ex-gas/FX), 21% digitally enabled sales, and 11% membership revenue expansion. Analysts project roughly $94.85 billion in revenue and $6.55 EPS, with focus likely on new U.S. warehouse openings, pricing discipline amid shifting inflation, and renewal rates near 90%. Recent monthly updates and store expansion plans provide the latest signals shaping expectations for the call.
