Corning beats Q1 earnings but stock falls on Q2 outlook

Corning (GLW) tumbled 10% premarket after Q2 sales guidance of $4.6 billion missed estimates of $4.67 billion. Despite beating Q1 earnings, a solar facility's extended maintenance shutdown weighed on the outlook. The company extended its Springboard growth plan to 2030 and announced a new photonics platform for Gen AI customers.
