Winston is serious
Mixed quality — meaningful strengths and weaknesses.

Coherent makes the lasers, optical components, and electronic parts that power fiber-optic networks, data centers, and industrial machines. Its products move data through the internet at high speeds and are used by telecom companies, cloud computing giants like Microsoft and Google, and manufacturers. The company is one of the largest makers of compound semiconductors and optical networking hardware in the world.

Coherent earns money by selling hardware — physical components and modules — to a wide range of business customers across North America, Europe, and Asia. It is a large company with operations spanning multiple continents, and its competitive edge comes from owning hard-to-replicate manufacturing processes for specialized materials like indium phosphide and silicon carbide. The biggest growth driver right now is surging demand for high-speed data center connections tied to artificial intelligence infrastructure, but the company carries significant debt from its 2022 merger with II-VI, which remains a financial risk.
