The Company recorded amortization expense related to intangible assets of $1,692 and $1,543 during the years ended September 30, 2025 and 2024, respectively. The weighted-average remaining lives of intangible assets as of September 30, 2025 were developed technology 5.0 years; customer relationships 11.6 years; and trade names 1.0 years.

During the year ended September 30, 2024, as a result of declining sales of AOCs and strategic decisions on investment across the Company’s product groups, the Company tested the related long-lived assets for possible impairment. Based on this test, the Company concluded that the carrying value of the AOCs asset group exceeded its estimated fair value, and the Company recorded an impairment charge of $1,333 to write down the carrying value of the long-lived assets (consisting of developed technology and customer relationships). The Company estimated the fair value of the AOCs asset group using a discounted cash flow model.

Estimated future amortization expense for intangible assets by fiscal year as of September 30, 2025 is as follows:

Years ending September 30,
2026	$	1,590
2027		1,510
2028		1,498
2029		1,498
