In the second quarter of fiscal 2025, the Company identified triggering events that required interim goodwill impairment testing for certain reporting units within the Infrastructure segment. Due to the Company’s strategic exit from the North American solar tracker market, increased competitive pressures in Brazil, and uncertainty surrounding European policies, an interim goodwill impairment test was conducted for the Solar reporting unit. The fair value of the reporting unit was estimated using a discounted cash flow analysis, which required the Company to estimate the future cash flows as well as select a risk-adjusted discount rate to measure the present value of the anticipated cash flows. The carrying amount of this reporting unit exceeded its estimated fair value, resulting in a goodwill impairment charge of $41,869 within the Infrastructure segment. Additionally, due to a reduction in forecasted sales primarily resulting from general market weakness in Australia, an interim goodwill impairment test was also performed for the Access Systems reporting unit. Using a discounted cash flow analysis, the Company determined that the carrying amount exceeded its estimated fair value, resulting in a goodwill impairment charge of $23,000 within the Infrastructure segment.

In the third quarters of fiscal 2025 and fiscal 2024, the Company performed its annual goodwill impairment assessment utilizing a quantitative test on all of its reporting units, with measurement dates of August 30, 2025 and September 1, 2024, respectively. Based on discounted cash flow analyses, the estimated fair value of all reporting units exceeded their respective carrying values in both periods and no impairments were recorded.

In the third quarter of fiscal 2023, the Company recognized impairment charges of $120,000 and $1,915 in the Agriculture and Infrastructure segments, respectively, using a discounted cash flow analysis, resulting from the Company’s annual goodwill impairment assessment as of September 2, 2023.

The weighted-average life of amortizing intangible assets is approximately three years. Amortization expense for the fiscal years ended December 27, 2025, December 28, 2024, and December 30, 2023 was $11,252, $14,214, and $19,455, respectively. Amortization expense is expected to average $9,166 annually over the next five fiscal years, based on amortizing intangible assets reported as of December 27, 2025.

In the second quarter of fiscal 2025, based on identified triggering events discussed above, the Company performed an impairment test on indefinite-lived trade names associated with the Solar and Access Systems reporting units. Using the relief-from-royalty method, the Company determined that the carrying amounts of the trade names exceeded their estimated

fair values. As a result, impairment charges of $4,830 were recognized within the Infrastructure segment. Additionally, in the second quarter of fiscal 2025, an impairment charge of $1,395 was recognized within the Agriculture segment for a customer relationship intangible asset that was determined not to be recoverable.

In the third quarter of fiscal 2025 and fiscal 2024, the Company tested its indefinite-lived trade names for impairment as part of its annual impairment assessment, with measurement dates of August 30, 2025 and September 1, 2024, respectively. The values of each trade name were determined using the relief-from-royalty method, and no trade names were determined to be impaired in either period.

In the third quarter of fiscal 2023, using the relief-from-royalty method, the Company recognized an impairment charge of $1,656 in the Infrastructure segment as a result of the Company’s annual indefinite-lived trade name impairment assessment as of September 2, 2023.
