Lumentum Sinks 15% as AI Chip Selloff Deepens

Lumentum (LITE) dropped 15% as Marvell (MRVL), which is acquiring it, fell due to an AI chip selloff. The deal, set to close in 2028, values Lumentum at 4.5 Marvell shares per Lumentum share, with no price protection. Other optical stocks like Ciena (CIEN) and Credo (CRDO) also declined.
