The earnings result
Amgen reported earnings on 2025-05-01 for the fiscal quarter ending Mar/2025. Reported EPS of $4.9 compared with a consensus estimate of $4.16, 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.
