Trex Company TREX Amortization of capitalized software and acquired intangible assets

The carrying amount of goodwill at March 31, 2026 and December 31, 2025 was $14.2 million. At March 31, 2026 and December 31, 2025 intangible assets were $22.5 million and $20.7 million, and accumulated amortization was $3.8 million and $3.5 million, respectively. The Company’s intangible assets, purchased in 2018, 2024, 2025, and 2026 consist of domain names and internal use software. Intangible asset amounts were determined based on the estimated economics of the asset and are amortized over the estimated useful lives on a straight-line basis over 15 years for domain names and 10 years for internal use software related to the Company's ERP and other platform tools, which approximates the pattern in which the economic benefits are expected to be received. The Company evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate an impairment. Intangible asset amortization expense for the three months ended March 31, 2026, and March 31, 2025, was $0.3 million and $0.1 million, respectively.
