1.On July 28, 2024, DuPont completed the acquisition of Donatelle Plastics, which is included in the Electronics & Industrial segment. See Note 3 for additional information.

2.In the third quarter 2024, the Company finalized the working capital settlements which impacted the residual goodwill recorded. See Note 4 for additional information.

The Company tests goodwill for impairment annually during the fourth quarter, or more frequently when events or changes in circumstances indicate that fair value is below carrying value.

Effective as of January 1, 2024, Electronics & Industrial realigned certain of its product lines making up its lines of business (Industrial Solutions, Interconnect Solutions and Semiconductor Technologies). During the first quarter of 2024, the realignment of the businesses within Electronics & Industrial served as a triggering event requiring the Company to perform an impairment analysis related to goodwill carried by certain reporting units as of January 1, 2024, prior to the realignment. As part of the realignment, the Company assessed and re-defined certain reporting units effective January 1, 2024, including reallocation of goodwill on a relative fair value basis, as applicable, to reporting units impacted. Goodwill impairment analyses were then performed for reporting units impacted in the Electronics and Industrial segment and no impairments were identified. The fair value of each reporting unit tested was estimated using a combination of a discounted cash flow model and market approach. The Company’s assumptions in estimating fair value include projected revenue, gross margins, selling, administrative, research and development expenses (SARD), capital expenditures, the weighted average cost of capital, the terminal growth rates, and the tax rate for the income approach and projected EBITDA and derived multiples from comparable market transactions for the market approach.

In connection with the preparation of the full year 2023 financial statements, macroeconomic triggering events required the Company to perform an impairment analysis of the goodwill associated with its Protection reporting unit, within Water & Protection as of December 31, 2023. As a result of the analysis performed, the Company concluded that the carrying amount of the Protection reporting unit exceeded its fair value resulting in a non-cash goodwill impairment charge of $804 million, which was recorded within “Goodwill impairment charge” on the Consolidated Statements of Operations for the year ended December 31, 2023. This reporting unit remains at risk for future impairment due to the fair value as of the date of impairment being equal to the carrying value as a result of the recorded impairment. Should macroeconomic conditions worsen, resulting in further recovery delays, or other events occur indicating that the estimated future cash flows of the reporting unit have further declined and the reporting unit is unable to meet or exceed its projections from 2024 and other future years, the Company may be required to record future non-cash impairment charges related to goodwill. As of September 30, 2024, the remaining carrying amount of goodwill within the Protection reporting unit was $4.8 billion.
