Goodwill and Other Intangible Assets

We completed our annual impairment test of goodwill and indefinite-lived intangible assets as of December 31, 2025. As allowed under the guidance, we elected to perform quantitative impairment tests of goodwill related to our Nissens Automotive and Engineered Solutions operating segments and our Nissens tradename of December 31, 2025. We performed qualitative impairment assessments for goodwill related to all our other operating segments and other intangible assets and concluded that it was not more likely than not that the fair value of any of our reporting units was less than carrying value, therefore no quantitative impairment tests were required. Based on the results of the tests, there was no goodwill impairment as of December 31, 2025.

While we concluded that we did not have a goodwill impairment charge as of December 31, 2025, and we do not believe that future impairments are probable, we will need to maintain the current ongoing performance levels at each of our reporting units in future periods to sustain their goodwill and indefinite-lived intangible assets carrying values.

Acquired Intangible Assets

Acquired identifiable intangible assets consist of (in thousands):


	December 31,
	2025						2024
	Gross		Accumulated Amortization		Net		Gross		Accumulated Amortization		Net
Customer relationships	$	323,312	$	(111,256)	$	212,056	$	303,547	$	(93,117)	$	210,430
Trademarks and trade names⁽ᵃ⁾	91,666		(5,284)		86,382		82,220		(4,995)		77,225

(a) Trademarks and trade names include $84.2 million of indefinite lived intangible assets which are not amortized.

Total amortization expense for acquired intangible assets was $18.4 million, $10.0 million and $8.5 million for the years ended December 31, 2025, 2024 and 2023, respectively. Based on the current estimated useful lives assigned to our intangible assets, amortization expense is estimated to be $18.8 million in 2026, $18.8 million in 2027, $18.8 million in 2028, $17.5 million in 2029 and $149.7 million million in the aggregate for the years 2030 through 2041.

For information related to identified intangible assets acquired in the Nissens acquisition, see Note 2, “Business Acquisitions and Investments,” of the notes to our consolidated financial statements.

Other Intangible Assets

Other intangible assets include computer software of $23.2 million and $21.4 million, at December 31, 2025 and 2024, respectively, less accumulated amortization of $19.8 million and $18.3 million as of December 31, 2025 and 2024, respectively. Computer software is amortized over its estimated useful life of 3 to 10 years. Amortization expense for computer software was $1.2 million, $0.8 million and $0.8 million for the years ended December 31, 2025, 2024 and 2023, respectively.

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.
