As of December 31, 2024, the carrying amount of goodwill was fully impaired. In September 2024 and June 2024, in consideration of the sustained decline in our stock price, industry developments, and our financial performance, we evaluated our current operating performance. Accordingly, we determined that there were indicators of impairment and a quantitative assessment was necessary. In the quantitative assessment, we estimated the fair value of our reporting unit utilizing an income approach, based on the present value of future discounted cash flows, which is classified as Level 3 in the fair value hierarchy. Significant estimates used to determine fair value include the weighted average cost of capital, growth rates, and amount and timing of expected future cash flows. As a result of the quantitative assessment, we determined that goodwill was impaired as the fair value of our reporting unit was less than the carrying value. As such, during the year ended December 31, 2024, we recorded impairment expense of $635.4 million equal to the excess of the carrying value of our reporting unit over the estimated fair value, limited to the remaining balance of goodwill, which was classified as impairment expense on our consolidated statements of operations.

During the years ended December 31, 2025, 2024 and 2023, intangible assets amortization expense was $4.3 million, $10.0 million and $24.4 million, respectively.

In conjunction with our goodwill impairment analysis in June 2024, we determined that there were indicators of impairment for our Busuu intangible assets and a recoverability test was necessary. In the recoverability test, we determined
that the expected future undiscounted cash flows for the asset group were not sufficient to recover the carrying value. We then proceeded in estimating the fair value of the asset group utilizing the income approach, based on a present value of future discounted cash flows, which is classified as Level 3 in the fair value hierarchy. Significant estimates used to determine fair value include the growth rates and amount and timing of expected future cash flows. As a result of the impairment test, we determined the asset group was impaired and recorded a $31.9 million impairment expense related to the intangible assets during the year ended December 31, 2024, which was classified as impairment expense on our consolidated statements of operations.

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.
