Item 2.02 Results of Operations and Financial Condition. Item 2.05 Costs Associated with Exit or Disposal Activities. On July 30, 2025 we determined to implement initiatives to reduce costs in the curamik® reporting unit in our AES operating segment. This determination was made in response to market conditions and once fully implemented, these actions are expected to reduce manufacturing costs and operating expenses in excess of $13.0 million on an annual run-rate basis. As a result of these intended actions, we expect to record expenses in the range of $12.0 million to $20.0 million, which are expected to comprise of employee severance costs, property, plant and equipment relocation and reinstallation costs, consulting fees and other miscellaneous cash costs. We expect the bulk of the cash outflows will occur in 2026, with some cash outflows occurring in second half of 2025. These proposed initiatives are subject to a consultation process with the applicable works council representatives for our Eschenbach, Germany facility, which we initiated on July 31, 2025.
