The earnings result
Costco reported earnings on 2024-03-07 for the fiscal quarter ending Feb/2024. Reported EPS of $3.71 compared with a consensus estimate of $3.6, a beat on the source's earnings measure.
An EPS comparison describes one part of the release. Revenue, segment performance, cash conversion, guidance and the conference-call discussion require the original company disclosures; the result alone does not establish why the stock moved.
