Lumentum added Thad Trent, Executive Vice President and Chief Financial Officer of onsemi, to its Board of Directors, expanding the board to nine members. The appointment takes effect immediately and brings additional finance and semiconductor manufacturing experience to the optical and photonics supplier as it targets growth tied to AI and cloud infrastructure.
Trent brings more than three decades of financial leadership across public technology companies. He joined onsemi as CFO in 2021 and previously served as CFO of Cypress Semiconductor from 2014 until Infineon Technologies acquired the company in 2020. Earlier in his career, he held senior finance roles at Wind River Systems and Wyle Electronics.
Lumentum positions its optical components and subsystems as foundational building blocks for telecom, enterprise, and data center networks, with growing relevance to AI-driven infrastructure buildouts. The company said Trent’s background in corporate finance, M&A, and in-house manufacturing aligns with its long-term strategy and operational priorities.
