Coherent has transitioned from a cyclical optical supplier to a strategic AI infrastructure enabler, supporting a structural rerating in valuation. Q3 revenue grew 27% and EPS 55%, with datacenter exposure rising to 75% and strong backlog visibility extending into 2028 and beyond. COHR's 6-inch indium phosphide ramp and broad AI ecosystem positioning underpin confidence in sustained high growth through FY2027 and FY2028.

Coherent Corp.'s Q3 FY2026 revenue rose 21% YoY to $1.81B while EPS surged 55% as margins expanded toward 39.6%.
