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
