What happened

Valuation-10.1%high confidence

Jabil reported strong fiscal Q4 2026 earnings—net revenue of $10.62B (+29% YoY) and core EPS of $4.40, both beating consensus—and raised full-year FY2027 guidance to $44.5B revenue and $17.55 core EPS, driven by robust AI data center demand (uk.investing.com, benzinga.com). Despite the beats and upbeat outlook, JBL fell 10.27% to $286.08 as investors engaged in profit-taking and weighed risks around heavy capacity expansion and supply constraints. Volume surged to 3.65x average for the session, indicating heightened selling pressure.
