GOODWILL AND OTHER INTANGIBLES
Goodwill
The Company has goodwill with a carrying value of $1,100.9 million as of December 31, 2025 and 2024 and performed its annual impairment assessment as of July 1, 2025 and 2024 concluding there was no impairment to goodwill. In addition, there were no events or circumstances that occurred during the second half of 2025 that would more-likely-than-not reduce the fair value of the Company’s reporting unit below its carrying value.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
