Coherent

What Coherent does

Coherent Corp. (NYSE: COHR), formerly II-VI Incorporated and rebranded following a major merger, is a Pennsylvania-domiciled, vertically integrated photonics and engineered materials company that designs and manufactures optical networking components, industrial laser systems, and specialty substrates for industrial and communications end-markets. Its technology platform spans silicon photonics, indium phosphide (InP) optoelectronics, VCSEL arrays, multiple laser modalities (CO2, fiber, DPSS, excimer, and ultrafast femtosecond), and silicon carbide (SiC) substrates for power semiconductors — covering the full photonic stack from photon generation through modulation, amplification, direction, and detection.

The company generates revenue primarily through direct enterprise sales of hardware (optical transceivers and modules, laser systems and sources, and engineered materials), supplemented by service and support contracts and an applied-engineering offering called Coherent Labs that engages in over 2,500 customer projects annually. Go-to-market combines a global field-sales force targeting hyperscale datacenter operators, telecom carriers, and major industrial OEMs with channel relationships to system integrators and OEMs that embed Coherent components into finished equipment. End-customer segments span datacenter and communications, industrial precision manufacturing, semiconductor and display capital equipment, automotive and EV/energy, life sciences and medical, scientific research, and aerospace/satellite/defense.

Coherent reports Q3 FY2025 revenue of $1.50 billion (+24% YoY) and GAAP gross margin of 35.2% (+491 bps YoY), with management guiding to >22% full-year FY2025 revenue growth. Its AI infrastructure exposure is anchored by a strategic partnership with NVIDIA, a silicon-photonics-based 1.6T-DR8 transceiver platform (using Marvell's Ara 3nm optical DSP), and an Optical Circuit Switch product line for GPU-to-GPU connectivity. The SiC substrate business was carved out into a majority-owned subsidiary in October 2023 with $1 billion of strategic capital from DENSO and Mitsubishi Electric, and the company employs approximately 5,000 people globally with manufacturing, R&D, and sales operations across the Americas, Europe, and Asia-Pacific (including a new Global Centre of Excellence in Chennai, India and a $50 million CHIPS Act-backed expansion of its Sherman, TX site).
