In accordance with FASB Topic 350, Intangibles—Goodwill and Other (“ASC 350”), goodwill is not subject to amortization but is tested for impairment at the reporting unit level annually in the third quarter. Additionally, the Company may perform interim tests of goodwill for impairment if an event occurs or circumstances change that could potentially reduce the fair value of a reporting unit below its carrying amount. The carrying value of each reporting unit is determined by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units. An impairment loss is recognized when the reporting unit’s carrying amount exceeds its estimated fair value.

The Company tests for impairment by either performing a qualitative evaluation or a quantitative test. The qualitative evaluation is an assessment of factors, including reporting unit specific operating results as well as industry, market and general economic conditions, to determine whether it is more likely than not that the fair values of a reporting unit is less than its carrying amount, including goodwill. The Company may elect to bypass this qualitative evaluation for some or all of its reporting units and perform a quantitative test. The quantitative test uses a combination of both an income approach and a market approach to determine the fair value of the reporting unit. The income approach utilizes the estimated discounted cash flows for the reporting unit, while the market approach utilizes comparable publicly-traded companies’ revenue and earnings

before interest, taxes, depreciation, and amortization (“EBITDA”) multiples. Estimates and assumptions used in the income approach to calculate projected future discounted cash flows included revenue growth rates, cost of sales, terminal growth rates, and a discount rate for each reporting unit. Discount rates are determined using a weighted average cost of capital for risk factors specific to each reporting unit and other market and industry data. The assumptions used are inherently subject to uncertainty and slight changes in these assumptions could have a significant impact on the concluded value. The estimates and assumptions applied represent a Level 3 measurement in the fair value hierarchy. Level 3 inputs are supported by limited or no market activity and reflect the Company’s assumptions in measuring fair value.

During the second quarter of 2025 the Company performed a quantitative assessment of its Tissue Technologies, Neurosurgery, and Instruments and ENT reporting units in accordance with ASC 350 due to the decrease in the price per share of the Company’s common stock related to a number of factors including recent tariff changes that have created broad economic uncertainty and the impact of quality, operational, and supply issues. The Company recognized an aggregate charge of $511.4 million in goodwill impairment expense in the consolidated statement of operations. The quantitative test for the Tissue Technologies reporting unit utilized a terminal growth rate of 2.5% and a discount rate of 13.5% in the income approach. The Company determined, after performing the quantitative analysis, that the fair value of the Tissue Technologies reporting unit was less than its carrying amount and recognized an impairment of $123.3 million. The quantitative test for the Neurosurgery reporting unit utilized a terminal growth rate of 2.5% and a discount rate of 13.5% in the income approach. The Company determined, after performing the quantitative analysis, that the fair value of the Neurosurgery reporting unit was less than its carrying amount and recognized an impairment of $249.0 million. The quantitative test for the Instruments and ENT reporting unit utilized a terminal growth rate of 2.5% and a discount rate of 12.0% in the income approach. The Company determined, after performing the quantitative analysis, that the fair value of the Instruments and ENT reporting unit was less than its carrying amount and recognized an impairment of $139.1 million.

The Company does not amortize intangible assets with indefinite lives but tests its intangible assets with indefinite lives for impairment annually in the third quarter in accordance with ASC 350. Additionally, the Company performs interim tests of its intangible assets with indefinite lives for impairment if an event occurs or circumstances change that could potentially reduce the fair value of a indefinite lived intangible asset below its carrying amount. The Company tests for impairment by either performing a qualitative evaluation or a quantitative test. The qualitative evaluation is an assessment of factors, including specific operating results as well as industry, market and general economic conditions, to determine whether it is more likely than not that the fair values of the intangible asset is less than its carrying amount. The Company may elect to bypass this qualitative evaluation and perform a quantitative test.

During the second quarter of 2025 the Company performed a quantitative assessment of its Codman tradename intangible asset in accordance with ASC 350 due to the decrease in the price per share of the Company’s common stock related to a number of factors including recent tariff changes that have created broad economic uncertainty and the impact of quality, operational, and supply issues. In performing this test, the Company utilized a discount rate of 14.5%. The assumptions used in evaluating the Codman tradename for impairment are subject to change and are tracked against historical results by management. Based on the results of the quantitative test, the Company recorded no impairment to the Codman tradename intangible asset.

Developed technologies and other definite-lived intangible assets are amortized over their estimated useful lives either using the straight-line method or, if reliably determinable, based on the pattern of which the economic benefit of the asset is expected to be utilized. Definite-lived intangible assets are periodically evaluated for impairment in accordance with FASB Topic 360, Property, Plant and Equipment (“ASC 360”) whenever events or changes in circumstances indicate that a definite-lived intangible asset’s carrying value may not be recoverable.

Total amortization of intangible assets for the three and six months ended June 30, 2024 was $25.4 million and $53.1 million, respectively. Of this amount, $21.7 million and $39.3 million, respectively, was related to amortization of technology based intangibles and included in cost of goods sold. $7.1 million related to the impairment of a customer relationship intangible and the remainder were included in intangible amortization in the statement of operations.

In the first quarter of 2024, due to third-party audit findings and an update to the estimated timeframe to resume the commercial distribution of products manufactured in the Boston facility, the Company elected to perform quantitative impairment testing on certain definite-lived intangible assets including completed technology and customer relationships in accordance with ASC 360. The Company recorded an impairment charge related to the definite-lived intangible asset associated with the customer relationships of $7.1 million in intangible asset amortization in the consolidated statement of operations. With respect to the definite-lived intangible assets associated with the completed technology of SurgiMend® and PriMatrix®, the Company determined that the carrying amount of these definite-lived intangible assets were recoverable and, therefore, the intangible assets were not deemed to be impaired. In the second quarter of 2024, the Company approved a plan to transition the commercial distribution of SurgiMend and PriMatrix from the Boston facility to the Company’s manufacturing facility in Braintree, Massachusetts (the “Braintree facility”). The Company considered the impact to the update to the estimated timeframe to resume the commercial distribution of products manufactured in the Boston facility on the assumptions used in the quantitative assessment of the definite-lived intangible assets completed in the first quarter of 2024, which did not require further evaluation for impairment. The carrying values of SurgiMend and PriMatrix are $29.2 million and $22.2 million, respectively, as of June 30, 2025.

The recent tariff changes imposed by the U.S. and other countries have created increased risks and uncertainties surrounding the Company’s future results of operations. President Trump has announced reciprocal tariffs on many countries with additional tariffs on the pharmaceutical industry to be announced in the near future. Certain countries, such as China, have responded with retaliatory tariffs. The assumptions used by the Company in its quantitative tests of goodwill and intangible assets are inherently subject to uncertainty and slight changes in these assumptions, including the extent and duration of any subsequent
