Coherent (COHR) Q3 FY26 earnings call

Coherent has crossed into a faster growth phase as AI datacenter optical demand converts into record backlog and near-term shipments, with management framing the June quarter as a new inflection point and fiscal '27 growth set to exceed fiscal '26. The thesis now hinges on execution — ramping supply-constrained indium phosphide and new OCS/CPO/multi-rail platforms — rather than demand, which management calls exceptional with no signs of attenuation.
