Amortization expense recorded on the intangible assets for the fiscal years ended June 30, 2025, 2024 and 2023 was $303 million, $288 million, and $414 million, respectively. The technology intangible assets are being amortized over a range of 60 to 240 months with a weighted-average remaining life of approximately 116 months, and the amortization is recorded in Cost of goods sold in our Consolidated Statements of Earnings (Loss). The customer lists are being amortized over 60 to 192 months with a weighted-average remaining life of approximately 138 months, and the amortization is recorded in SG&A in our Consolidated Statements of Earnings (Loss).
Amortization expense in the fiscal year ended June 30, 2025 includes a total of $17 million of impairment charges in the Materials segment related to the abandonment of certain purchased technology and licenses, with $14 million recorded in cost of goods sold and $3 million recorded in R&D in our Consolidated Statements of Earnings (Loss). There were no impairment charges included in amortization expense in the fiscal year ended June 30, 2024.
Amortization expense in the fiscal year ended June 30, 2023 includes a total of $39 million of impairment charges, with $33 million in the Materials segment and $7 million in the Networking segment. $25 million of the impairment charges related to the abandonment of certain purchased technology and customer lists, with $8 million recorded in Cost of goods sold and $18 million recorded in SG&A in our Consolidated Statement of Earnings (Loss). $14 million of impairment charges, recorded in SG&A, related to the abandonment of indefinite-lived trade names primarily due to the fiscal 2023 rebranding of the Company as Coherent Corp.
In the fourth quarter of fiscal year 2025, we completed our impairment test of our $430 million indefinite-lived Coherent trade name acquired in the Merger, concluding it was not impaired.
The estimated amortization expense for existing intangible assets for each of the five succeeding years is as follows ($000):

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.
