Michael D. Slessor has run FormFactor since December 2014, when he became chief executive. He has been president and a director since October 2013, and the insider record has him filing as an officer and director of the company since 2013. He arrived with a takeover: he was president and chief executive of MicroProbe Incorporated from July 2008 until FormFactor closed its acquisition of MicroProbe in October 2012, then ran that product group as a senior vice president for a year before taking the top job. Earlier he held management, product marketing and applications engineering posts in the semiconductor industry, mostly at KLA-Tencor. He holds a doctorate in aeronautics and physics from the California Institute of Technology. 1234

The finance seat changed hands in 2025. Aric McKinnis has been chief financial officer since August 2025; he joined FormFactor in August 2019 and was vice president and corporate controller before the promotion, after spells as corporate controller at MKS Instruments and Electro Scientific Industries and as a manager at Deloitte. He follows Shai Shahar, chief financial officer from 2018 to August 2025 and then senior vice president and executive advisor from September through December 2025. The insider record has McKinnis first filing in 2025 and Shahar last filing in 2025. 564

Seven directors stand for election this year: Rebeca Obregon Jimenez, on the board since September 2019; Sheri Rhodes, since December 2019; Slessor, since October 2013; Kelley Steven-Waiss, since August 2015; Thomas St. Dennis, the chairperson, since September 2010; Jorge Titinger, since June 2021; and Brian White, since September 2022. Kevin Brewer, a director since March 2024, is retiring at the annual meeting and will not stand again, taking the board from eight members to seven. Every director other than Slessor is independent on the board's own determination. St. Dennis ran the company himself, as chief executive from September 2010 through December 2014, and was executive chairperson from October 2013 to February 2016 before taking the chair. Titinger is a returner: the insider record has him first filing at FormFactor in 2007, and the proxy says he held senior executive positions there before joining Verigy. 789101112134

FormFactor counted 2,153 regular full-time employees at the close of fiscal 2025 on 27 December. Most of them make things: 1,298 in operations, against 422 in research and development, 235 in sales and marketing and 198 in general and administrative work. By region, 1,553 were in North America, 325 in Asia and 275 in Europe. The Probe Cards segment held 1,579 of them, the Systems segment 377 and corporate functions 197. Nearly all the manufacturing staff sit in California, Oregon and Germany, and the company also draws on staffing firms for factory labor. 141516
