GOODWILL AND INTANGIBLE ASSETS
Goodwill
The Company’s goodwill arose from the GQ Bio Acquisition in February 2025 (for more information, see Note 4, GQ Bio Therapeutics Acquisition). As discussed below, the Company previously had goodwill resulting from the acquisition of Pacira Pharmaceuticals, Inc. (the Company’s California operating subsidiary) from SkyePharma Holding, Inc. (now a subsidiary of Vectura Group plc, a subsidiary of Molex Asia Holdings Ltd.) in 2007, the MyoScience Acquisition in 2019 and the Flexion Acquisition in 2021. The change in the carrying value of the Company’s goodwill is summarized as follows (in thousands):
| | | | | | | | |
| | Carrying Value |
| Balance at December 31, 2023 | | $ | 163,243 | |
| Goodwill impairment | | (163,243) | |
| Balance at December 31, 2024 | | — | |
| Goodwill arising from the GQ Bio Acquisition | | 17,988 | |
| Foreign currency adjustments | | 2,226 | |
| Balance at December 31, 2025 | | $ | 20,214 | |
Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in a business combination and is subject to impairment testing at least annually or upon the occurrence of a triggering event that could indicate a potential impairment. During the three months ended September 30, 2024, the FDA approved a generic competitor to EXPAREL and a U.S. District Court ruled that one of the Company’s EXPAREL patents was not valid (for more information, see Note 20, Commitments and Contingencies). The Company determined that these events, combined with a subsequent decrease in the Company’s common stock price, indicated that it was more likely than not that the fair value of goodwill may be less than its carrying value, which required the Company to perform a quantitative impairment test. This was performed by comparing the fair value of the Company to its carrying value. If the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, impairment is indicated, requiring recognition of a goodwill impairment charge up to the carrying value of goodwill. The fair value of the Company was calculated through an income approach, in which the Company calculated the fair value based on the present value of estimated future cash flows. Considerable management judgment is necessary to evaluate the impact of operating and macroeconomic changes and to estimate the future cash flows used to assume fair value. The Company’s estimates of future cash flows consider past performance, current and anticipated market conditions, internal projections and operating plans which incorporate estimates for sales growth and future margins. Additional assumptions include forecasted growth rates, estimated discount rates and the probability of success for the Company’s product pipeline candidate products. The assumptions also reflect current and anticipated market conditions and are consistent with those that would be used by other marketplace participants for similar valuation purposes. Such assumptions are subject to change due to changing economic and competitive conditions. The conclusion of the income approach as of September 30, 2024 resulted in the carrying value of the Company exceeding its fair value by more than the goodwill balance. As a result, the then-goodwill balance of $163.2 million was fully impaired during the three months ended September 30, 2024 and the Company had no remaining goodwill balance at December 31, 2024.
During the year ended December 31, 2025, the Company conducted the annual impairment assessment for its goodwill and concluded there was no impairment as of that date.
Intangible Assets
Intangible assets, net, consist of the IPR&D from the GQ Bio Acquisition and Flexion Acquisition, developed technology from the Flexion Acquisition and MyoScience Acquisition and customer relationships from the MyoScience Acquisition and are summarized as follows (dollar amounts in thousands):
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| December 31, 2025 | | Gross Carrying Value | | Foreign Currency Adjustments | | Accumulated Amortization | | Intangible Assets, Net | | Weighted-Average Useful Lives |
| Developed technologies | | $ | 590,000 | | | $ | — | | | $ | (256,213) | | | $ | 333,787 | | | 10 years, 5 months |
| Customer relationships | | 90 | | | — | | | (61) | | | 29 | | | 10 years |
| Total finite-lived intangible assets, net | | 590,090 | | | — | | | (256,274) | | | 333,816 | | | |
| Acquired IPR&D | | 31,500 | | | 2,784 | | | — | | | 34,284 | | | |
| Total intangible assets, net | | $ | 621,590 | | | $ | 2,784 | | | $ | (256,274) | | | $ | 368,100 | | | |
| | | | | | | | | | |
| December 31, 2024 | | Gross Carrying Value | | Foreign Currency Adjustments | | Accumulated Amortization | | Intangible Assets, Net | | Weighted-Average Useful Lives |
| Developed technology | | $ | 590,000 | | | $ | — | | | $ | (198,934) | | | $ | 391,066 | | | 10 years, 5 months |
| Customer relationships | | 90 | | | — | | | (52) | | | 38 | | | 10 years |
| Total finite-lived intangible assets, net | | 590,090 | | | — | | | (198,986) | | | 391,104 | | | |
| Acquired IPR&D | | 34,866 | | | — | | | — | | | 34,866 | | | |
| Total intangible assets, net | | $ | 624,956 | | | $ | — | | | $ | (198,986) | | | $ | 425,970 | | | |
Amortization expense on intangible assets was $57.3 million for both the years ended December 31, 2025 and 2024.
Assuming no changes in the gross carrying amount of these intangible assets, the future estimated amortization expense on the finite-lived intangible assets will be $57.3 million each year from 2026 to 2030, $37.4 million in 2031, $7.9 million in 2032 and $2.2 million in 2033.
As part of the GQ Bio Acquisition, the Company recognized $22.5 million of acquired IPR&D in February 2025. See Note 4, GQ Bio Therapeutics Acquisition, for more information.
The Company reviews its indefinite-lived intangible assets for impairment annually and whenever an event or change in circumstances arises that indicates the carrying amount of an indefinite-lived intangible asset is at risk of not being recoverable. During the year ended December 31, 2024 and 2023, the Company conducted the annual impairment assessment for its acquired IPR&D and concluded there was no impairment as of that date. During the three months ended September 30, 2025, the Company determined the fair value of the ZILRETTA acquired IPR&D for the treatment of shoulder OA pain may be at risk of impairment due to revised completion timelines for clinical trials and commercial availability which directly impacted revenue forecasts, among other factors. The Company determined that these events indicated that it was more likely than not that the fair value of the acquired IPR&D may be less than its fair value. The impairment assessment was conducted through a recoverability test by comparing the $33.9 million carrying value of the asset against the fair value through a discounted cash flow model based on new facts and circumstances. The assessment resulted in a fair value of $8.0 million. An impairment of $25.9 million was recognized within contingent consideration gains, acquisition-related expenses, restructuring and other in the consolidated statements of operations for the three months ended September 30, 2025 based on the amount its previous carrying value exceeded its updated fair value.
During the year ended December 31, 2025, the Company conducted the annual impairment assessment for its acquired IPR&D and concluded there was no impairment as of that date.
