In January 2025, the Company began the early phases of restructuring the Helios Center of Engineering Excellence (“HCEE”). As the next phases of the restructuring plan begin, management plans to close the San Antonio office during the second quarter of 2025, reassign resources to the operations at our other major facilities across the business, and eliminate certain positions. As a result of this change in the HCEE business operations, the workforce intangible asset associated with the HCEE acquisition was reviewed by management and it was determined that the remaining net book value of the asset should be amortized over a useful life ending during the second quarter of 2025. This resulted in an increased $0.5 amortization expense in the three months ending March 29, 2025, associated with this intangible asset.
