PHOENIX, Ariz. – Jan. 28, 2021 – ON Semiconductor (Nasdaq: ON) announced today that Thad Trent will join ON Semiconductor as executive vice president and chief financial officer (CFO) effective Feb. 16, 2021. Trent joins ON Semiconductor as a nearly 30 year finance veteran of the tech industry. Trent has held several leadership roles throughout his career, most recently as CFO at Cypress Semiconductor responsible for strategic planning, accounting, investor relations, tax, corporate development and information technology. Under his leadership, revenue increased from $723 million to $2.5 billion and the enterprise value increased by five times within five years. Trent has a proven track record of driving sustainable financial performance, transformative mergers and acquisitions, operational excellence, process efficiency, financial leadership and robust compliance.

“I have full confidence that Thad’s wealth of experience to the role and a depth of understanding of the transformation underway in our industry will add tremendous value to our organization,” said Hassane El-Khoury, president and CEO at ON Semiconductor. “He has the skillset needed to take our company into its next phase as we further focus on accelerating revenue and gross margin while enhancing stakeholder value. We are excited to enter this next phase of growth for the company.”

Bernard Gutmann has decided to retire from his position as executive vice president and CFO of the company after a nearly four decade career in finance with ON Semiconductor and Motorola. Gutmann will remain an advisor until April 2021 to ensure a smooth transition.

“During the past several decades of my career here, it has been wonderful to be a part of our company’s success and foundation building – starting from my work on the company’s initial public offering (IPO) in 2000,” said Gutmann. “I wish our company a bright future and outlook as I embark on this next phase of my life, focusing on my family in retirement.”

“The foundation that Bernard has set during his tenure at our company will enable us to build upon our future strategies,” said El-Khoury. “We thank Bernard for his dedication to his team, ON Semiconductor and key stakeholders during his tenure at our company.”
