Chemours consists of four operating segments: Thermal & Specialized Solutions, Titanium Technologies, Advanced Performance Materials, and Performance Chemicals and Intermediates (included in Other Segment). The Company defines its reporting units as operating units or one level below its operating segments. In 2024 and 2023, the Company had three reporting units for goodwill testing, which align with the Company's operating segments: Thermal & Specialized Solutions, Titanium Technologies, and Advanced Performance Materials. The Company completes its annual goodwill impairment test on October 1 each year, or more frequently if triggering events indicate a possible impairment. The Company continually evaluates financial performance, economic conditions and other recent developments in assessing if a triggering event indicates that the carrying values of goodwill or long-lived assets are impaired.

The total accumulated impairment losses included in the Company’s goodwill balance at December 31, 2024 and 2023 amounted to $56 and $0, respectively.

During the third quarter of 2024, the Company reviewed recently released third-party industry projections, which for hydrogen reflected lower end-market demand as well as slower market growth through 2030 and a more uncertain long-term growth trajectory beyond 2030. In response to these negative market outlook developments as well as increased commercial headwinds due to limited cyclical end-markets recovery and competitive intensity, the Company has revised its financial projections for the Advanced Performance Materials business which includes reductions to its investment plans. The Company concluded that these market developments, as well as the Company's revised financial projections to reflect these events, represented a triggering event for the Company's Advanced Performance Materials reporting unit and associated goodwill, as well as the related asset group, during the third quarter of 2024. As a result of this conclusion, the Company completed an interim impairment assessment as of August 31, 2024 for its Advanced Performance Materials reporting unit and the related asset group.

The Company concluded that the undiscounted cash flows exceeded the carrying value of the long-lived assets, and that an impairment did not exist. In completing an interim quantitative goodwill impairment test, the Company compared the reporting unit's fair value to its carrying value in order to determine if an impairment charge was warranted. The fair value of the Company's Advanced Performance Materials reporting unit was determined by using a combination of discounted cash flow models (a form of the income approach) and the guideline public company method (a form of the market approach). These valuation models incorporated a number of assumptions and judgments surrounding general market and economic conditions and internal forecasts of future business performance that are based on short- and long-term revenue growth rates, EBITDA margins and prospective financial information surrounding the future cash flows of the reporting unit. Discount rate and market multiple assumptions were determined based on relevant peer companies in the chemicals sector. As a result of the analysis performed, the Company concluded that the carrying amount of the Advanced Performance Materials reporting unit exceeded its fair value resulting in a non-cash goodwill impairment charge of $56, which is recorded within “Goodwill impairment charge” on the Consolidated Statements of Operations for the year ended December 31, 2024.

No further goodwill impairments were recorded for the years ended December 31, 2024 and 2023, as the fair values of the Company's other reporting units that carry goodwill exceeded each respective reporting unit's carrying amount on October 1, 2024 and 2023.

The following table sets forth the gross carrying amounts and accumulated amortization of the Company’s other intangible assets by major class at December 31, 2024 and 2023.

The aggregate pre-tax amortization expense for definite-lived intangible assets was less than $1, $10, and $5 for the years ended December 31, 2024, 2023 and 2022, respectively. Less than $1 of pre-tax amortization expense is estimated annually for 2025, 2026, 2027, 2028, and 2029. Definite-lived intangible assets are amortized over their estimated useful lives, generally for periods ranging up to 20 years. The reasonableness of the useful lives of these assets is periodically evaluated. The Company does not have any indefinite-lived intangible assets.
