Michael Sheaffer to retire in July 2024 following a successful search for successor

Onto Innovation Inc. (NYSE: ONTO) (“Onto Innovation,” “Onto,” or the “Company”) today announced that Michael Sheaffer plans to retire from the Company in July this year. A successor search has now been successfully completed with Sidney Ho joining Onto Innovation as vice president of investor relations. Mr. Sheaffer will remain fully engaged in the investor relations role and will be the primary investor contact point until Mr. Ho assumes that responsibility during the Company’s investor meetings at SEMICON® West in July 2024.

Mr. Sheaffer, 74, joined Rudolph Technologies in 2017 as senior director of investor relations and continued that role for Onto Innovation following the merger of Rudolph Technologies and Nanometrics. He shared, “It has been a great pleasure to finish my career at Onto Innovation where we created a new company supporting the semiconductor value chain while growing revenues 3X since I joined. Over the next few months, I am pleased to help Sidney transition into this exciting role.”

Mr. Ho joins Onto with more than 20 years of sell-side equity research experience covering the semiconductor, semiconductor capital equipment, and IT hardware industries. Most recently, he spent 10 years as a senior analyst at Deutsche Bank. Prior to that, he was a research analyst at Nomura Securities, Citi, and Merrill Lynch. Prior to his career in equity research, he spent six years in investment banking and public accounting. He said, “Onto offers a unique value proposition by having process control tools and software used across multiple markets in the semiconductor supply chain. There are multiple inflection points happening across the industry that have strong secular growth potential. I look forward to effectively communicating our corporate strategies tied to that growth and Onto’s financial performance to create long-term value for our investors.”

Mike Plisinski, Onto’s chief executive officer, commented, “We are excited to have Sidney join the Onto Innovation team. Sidney brings decades of valuable sell-side experience to the company. His extensive knowledge of the industry drivers and global relationships across the investment community will broaden our outreach while increasing support for our existing investors.”

He continued, “Mike has worn many hats over the years as we grew our market cap by 14X during his time with us. He worked tirelessly throughout, and we wish him a well-deserved and relaxing retirement!”
