During the 2024 annual review of goodwill in the fourth quarter, management performed quantitative assessments on the Engine Products and Engineered Structures reporting units and qualitative assessments on the Fastening Systems and Forged Wheels reporting units. The estimated fair values of the reporting units exceeded their respective carrying values in excess of 60%; thus, there were no goodwill impairments. Howmet uses a DCF model to estimate the current fair value of the reporting unit, which is compared to its carrying value, when testing for impairment. Management believes forecasted cash flows are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales growth, production costs, and discount rate. Assumptions can vary among the reporting units. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The WACC rate for the individual reporting units is estimated with the assistance of valuation experts. The annual goodwill impairment tests in the fourth quarters of 2024, 2023, and 2022 indicated that goodwill was not impaired for any of the Company’s reporting units. If actual results or external market factors decline significantly from management’s estimates, future goodwill impairment charges (or the amount by which the carrying amount exceeds the reporting unit’s fair value without exceeding the total amount of goodwill allocated to that reporting unit) may be necessary and could be material.
