Goodwill Impairment Charge - Advanced Polymer Technologies
During the second quarter of 2025, the announcements and subsequent modifications of international tariffs escalated global trade tensions and contributed to increased consumer uncertainty, which negatively impacted parts of our businesses, particularly APT. As a result, we conducted an analysis of the APT reporting unit’s goodwill, intangible assets, and long-lived assets.
Based on the results of the quantitative analysis, we concluded that the carrying value of the APT reporting unit exceeded its fair value. As a result, we recorded a non-cash goodwill impairment charge of $183.8 million, representing all of the goodwill associated with the APT reporting unit. The charge is included within Goodwill impairment charge on the condensed consolidated statements of operations for the nine months ended September 30, 2025.
There were no events or circumstances indicating that goodwill might be impaired as of September 30, 2026.
