Amortization expense was $16.4 million, $17.2 million and $20.3 million in the years ended December 31, 2024, 2023 and 2022, respectively. The weighted average remaining amortization period for finite-lived intangible assets was 9.5 years as of December 31, 2024 and 10.0 years as of December 31, 2023. Amortization expense is expected to total approximately $15 million in 2025 through 2027, $14 million in 2028 and $13 million in 2029.
As further discussed in Note 4, “Asset Impairments and Other Charges and Credits,” during 2024 the Company made a strategic decision to exit an underperforming service offering within the Completion and Production Services segment. As a result of this action, the segment recognized non-cash impairment charges of $9.1 million related to customer relationships and $1.7 million related to tradenames. In 2023, no impairment of other intangible assets was required.

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.
