AXT, Coherent, and Lumentum are experiencing significant stock rallies driven by record-high price increases for indium phosphide (InP) substrates, a critical component in optics. A United Daily News report out of Taipei highlighted severe undersupply and Q4 price hikes exceeding 10% for InP, directly benefiting AXT as a leading producer. Coherent and Lumentum, major consumers of InP, are also seeing gains, with both companies expanding their internal InP capacities and benefitting from strong VR200 NVL72 ramps in the AI data center sector.
