Lumentum Q1 adjusted EPS $4.57 beats $4.21 estimate; Q2 revenue guidance $1.58B-$1.63B tops $1.48B

The margin beat matters more than the EPS beat: adjusted gross margin expanding roughly two points past consensus suggests pricing power or a richer product mix, not just cost discipline. The guidance gap is the real signal — a second-quarter revenue range well above consensus implies demand visibility extending beyond the quarter, which is the kind of forward confidence that moves sentiment in a sector where optical component suppliers are often judged on order momentum. Worth watching is whether that margin level holds as volumes scale, and whether the premarket move holds through the session.
