Q1 2026 Organizational Update
Effective in January 2026, Diversified Industrials realigned certain product lines. The realignment of the businesses within Diversified Industrials served as a triggering event requiring the Company to perform an impairment analysis related to goodwill carried by the impacted reporting units in January 2026. As part of the realignment, the Company assessed and re-defined certain reporting units effective January 2026, including reallocation of goodwill on a relative fair value basis. Goodwill impairment analyses were then performed for reporting units impacted in the Diversified Industrials segment. The results of the assessments indicated that it is not more likely than not that the fair values of the reporting units impacted were less than their carrying values. Therefore, no impairments were identified.

Q1 2025 Goodwill Impairment
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 in the first quarter of 2025, in preparation for the Electronics Separation, the Company realigned its management and reporting structure (the "Q1 2025 Segment Realignment"). In connection with the Q1 2025 Segment Realignment, the Company realigned its operating and reportable segments, which changed the composition of certain reporting units. During the first quarter of 2025, the associated reporting units' goodwill and indefinite-lived intangible assets were assessed for impairment before and after the Q1 2025 Segment Realignment.

After the Q1 2025 Segment Realignment, the Company performed quantitative testing on all six reporting units. No impairments were identified except for the Aramids reporting unit (i.e., the aggregation of the Nomex® and Kevlar®). The Company concluded that the carrying amount of the Aramids reporting unit exceeded its fair value resulting in a non-cash goodwill impairment charge of $768 million. Due to the Aramids Divestiture, this charge is now reflected within discontinued operations.
