COHERENT CORP. (COHR)

Coherent Corp. is a vertically integrated manufacturing company that develops, manufactures, and markets lasers, transceivers, and other optical and optoelectronic devices, modules, and systems, as well as engineered materials. Its products serve the datacenter, communications and industrial markets. The company says it has deep technical expertise in materials growth, specialty materials, semiconductor and high-power lasers, passive optics and transceivers, and that many of its products include custom software developed in-house.

Since July 1, 2025, Coherent has reported two segments: Datacenter & Communications, and Industrial. They replaced the former Networking, Materials and Lasers segments. Datacenter & Communications offers transceivers, co-packaged optics, optical circuit switches, VCSELs, edge-emitting and pump lasers, optical amplifiers, transport products and other components and subsystems. It is a supplier of optical transceivers for AI datacenters, with an in-house platform spanning lasers, detectors, ICs, photonic integrated circuits and thermal solutions. The company is expanding 6-inch indium phosphide and GaAs VCSEL capacity, including at its Sherman, Texas facility. It also entered a multi-year supply agreement with NVIDIA. Industrial offers excimer, solid-state and CO2 lasers, laser systems, optics, and engineered materials such as ZnSe, ZnS, GaAs, InP, GaSb and SiC, along with ceramics, metal-matrix composites and thermoelectric components.

Coherent's customers include optical component and module makers, networking equipment manufacturers, datacenter operators, enterprises, telecom service providers, OEMs and end users. Industrial markets include precision manufacturing (medical devices, EV battery welding, additive manufacturing), semiconductor and display capital equipment, life sciences, scientific research, consumer electronics (3D sensing in smartphones, AR/VR and other devices), and automotive and wireless applications using SiC substrates. Some customers are in aerospace and defense. Two customers each accounted for more than 10% of fiscal 2026 revenue. Products are sold through a direct sales force, representatives, distributors and systems integrators.

Coherent is headquartered in Saxonburg, Pennsylvania, with R&D, manufacturing and sales facilities worldwide. Principal U.S. production and R&D sites are in California, Connecticut, Delaware, New Jersey, Pennsylvania and Texas. Non-U.S. sites are in China, Finland, Germany, Malaysia, the Philippines, Singapore, South Korea, Sweden, Switzerland, the United Kingdom and Vietnam. It had about 51,000 employees at June 30, 2026, most in manufacturing and mainly in Asia-Pacific. Inputs such as InP substrates, ICs, DSPs, housings and optical components come from third-party suppliers. In the Industrial segment, some key materials and components come from sole- or limited-source suppliers. It also uses contract manufacturers working from its proprietary designs. The company competes on materials-to-systems capabilities, intellectual property, scale, quality, delivery and technical support, and invests in R&D on transceivers, CPO, optical circuit switches, pump lasers and semiconductor devices.
