(1) At December 31, 2025, accumulated goodwill impairment was $80.8 million.
In the third quarter of 2025, we performed our quantitative impairment assessments for each of our two reporting units at September 30, 2025.
For our quantitative assessments, we estimated the value of each of our reporting units using both a discounted cash flows (“DCF”) analysis and a multiple of expected future cash flows, such as those used by third-party analysts. The DCF analysis included market participant weighted average cost of capital, revenue, gross margin, capital expenditures, and long-term growth rates based on historical information and our best estimate of future forecasts. The market approach involved significant judgment, including the selection of an appropriate peer group, selection of valuation multiples, and determination of the appropriate weighting in our valuation model. These assumptions included the use of significant unobservable inputs, representative of a Level 3 fair value measurement.
Based on our quantitative assessments, mainly related to a decline in the trading price of our Common Stock and our market capitalization, we concluded that the calculated fair value of our Rubber Carbon Black (“RCB”) and Specialty Carbon Black (“SCB”) reporting units were lower than their respective book values. In our Rubber reporting unit, elevated levels of low value tire imports from Asia during 2025 have directly impacted our demand in core Western markets and our overall profitability. In our Specialty reporting unit, persistently soft industrial economies coupled with uncertainty related to global trade, tariffs and regulatory matters have impacted our demand and portfolio mix. As a result, we performed quantitative impairment assessments for each of our two reporting units at September 30, 2025. As a result, we recognized a non-cash goodwill impairment charge of $80.8 million in the third quarter of 2025 with respect to both reporting units. No tax benefit was recorded because we determined it is a non-tax-deductible expense.
There was no goodwill impairment charge in 2024 or 2023.

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.
