Thomas Sonderman has been chief executive since December 2020 and a director since October 2020, and he has run the operating subsidiary, SkyWater Technology Foundry, since October 2017, the year the plant was cut loose from Cypress Semiconductor. He was president as well from December 2020 to September 2023. Before SkyWater he was vice president and general manager of the Integrated Solutions Group at Rudolph Technologies from January 2014 to October 2017, and earlier he worked at GLOBALFOUNDRIES and AMD, where he sat on the executive team that spun AMD's manufacturing out to create GLOBALFOUNDRIES. The annual report calls him the author of 50 patents; the company itself owns none. 123456

Three other executive officers are named. John Sakamoto has been president and chief operating officer since September 2023, in charge of day to day business and manufacturing; he came from Marvell Technology Group, where he ran the Processing Business Unit from November 2019, after 25 years in senior roles at Altera, Intel and Marvell. Steve Manko has been chief financial officer since December 2020 and finance chief of the operating subsidiary since July 1, 2020, after consulting for it from early 2019; before that he was a managing director at Riveron Consulting, and earlier still at Ernst & Young. Christopher Hilberg has been secretary since April 2022, general counsel since August 2022 and chief risk and compliance officer since May 2024, after a spell as a senior legal director at Best Buy from July 2017 to November 2021. 7891011121314

The board had nine directors going into the 2026 annual meeting, seven of them independent under the Nasdaq test. Timothy E. Baxter, an operating partner at Centre Partners Management and before that president and chief executive for North America at Samsung Electronics from December 2006 to May 2019, joined in March 2025 and has chaired the board since May 2025. Loren A. Unterseher, a director since October 2020, is managing partner of Oxbow Industries, the investor that bought the plant out of Cypress, and beneficially owned about 19.68% of the shares in April 2026, with Oxbow's CMI Oxbow Partners holding 9.13%. Public service is well represented: Edward M. Daly commanded the Army Materiel Command from July 2020 to May 2023, and Tammy J. Miller was lieutenant governor of North Dakota from January 2023 to December 2024. On the record this site holds, 27 people have filed insider reports and 14 filed in the last fifteen months; every one of those last filed on the day the sale to IonQ closed. 151617181920212252324

At the end of fiscal 2025 the company counted 1,551 employees, all of them in the United States. None are covered by a collective bargaining agreement and the company says it has never had a work stoppage. The Texas plant came with its workforce: the purchase took over substantially all of the property, plant and equipment, the employees and certain other assets of Infineon's fab in Austin. Some subsidiaries hold government issued facility security clearances and some employees hold personal ones, which the filing says are needed for certain government contracts, take a long time to obtain and are hard to recruit for. 25262728
