The earnings result
Regeneron Pharmaceuticals reported earnings on 2022-02-04 for the fiscal quarter ending Dec/2021. Reported EPS of $23.72 compared with a consensus estimate of $18.49, 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.
