Goodwill
During the year ended December 31, 2025, the Company bypassed the qualitative test and performed a quantitative assessment using a combination of an income and a market approach to determine the fair value of its reporting unit. Under the income approach, fair value was estimated using a discounted cash flow method, which incorporated cash flow projections and a discount rate. The discount rate was developed using a weighted average cost of capital and other market and industry data. Under the market approach, fair value was estimated using a guideline public company method, which incorporated market-based revenue multiples derived from comparable companies. The significant assumptions used in these approaches include projected revenue, the discount rate (inclusive of a company-specific risk premium), and selected revenue multiples, which represented significant unobservable inputs and therefore are classified as Level 3 inputs. To assess the reasonableness of the concluded fair value, the Company also performed a reconciliation to market capitalization, which included an implied control premium and other relevant market considerations.
There were no changes in the carrying amount of goodwill during the years ended December 31, 2025 and 2024.
Intangible Assets
Amortization of finite-lived intangible assets is computed using the straight-line method over the estimated useful life of the asset of up to 20 years and is reflected within “Amortization of intangibles” on the consolidated statements of operations. Amortization expense of $12.9 million and $17.4 million was recognized for the years ended December 31, 2025 and 2024, respectively.
During the year ended December 31, 2024, the Company determined that certain of its finite-lived intangible assets related to the acquisition of Ab Initio in July 2019 were fully impaired, and recorded a $1.2 million write-off of the net carrying value. In addition, the Company recorded a $2.7 million impairment of certain small molecule ion channel intangible assets during the year ended December 31, 2024. The impairment charges were recorded as “Amortization of intangibles” in the consolidated statements of operations. For the year ended December 31, 2025, there was no impairment of intangible assets with finite lives.
The remaining weighted-average useful life of definite lived intangible assets is 10.1 years. At December 31, 2025, future amortization expense on intangible assets is estimated to be as follows (in thousands):
| | | | | | | | |
Years Ending December 31, | | Amount |
| 2026 | | $ | 12,912 | |
| 2027 | | 12,912 | |
| 2028 | | 12,912 | |
| 2029 | | 12,912 | |
| 2030 | | 12,192 | |

Total future amortization expense | | $ | 125,149 | |
