Costco (COST) Q4 2026 (USD): EPS 6.75 (exp. 6.54), Total Revenue 95.7bln (exp. 95.0bln)

For this name, the lines that have tended to drive the after-hours tape are not EPS or total revenue but the comparable sales split, particularly the US and e-commerce comps, alongside membership fee income and renewal rates, since the fee stream is the highest-margin component and the most sensitive to any sign of churn. The distinction worth drawing is between a beat driven by traffic and basket versus one flattered by a lower tax rate or share count, with the former treated as durable and the latter typically faded. The follow-ons are the monthly comps cadence the company reports between quarters, any colour on wage and freight cost trajectory on the call, and the recurring question of a membership fee increase, which has historically been telegraphed well in advance and priced as a positive catalyst rather than a surprise. Richly valued defensives of this kind have tended to see muted upside reactions on beats and asymmetric downside on misses, so the bar set by positioning matters as much as the print itself.
