In consideration for certain technology, manufacturing, distribution, and selling rights and licenses granted to the Company, the Company has agreed to pay royalties on sales of certain products that it sells. The royalty payments that the Company made under these agreements were not significant for any of the periods presented.

In the ordinary course of its business, the Company is involved in, from time to time, various legal actions, including any matters described below, involving product liability, employment, intellectual property and commercial disputes, shareholder related matters, environmental proceedings, tax disputes, and governmental proceedings and investigations, some of which have been settled by the Company. In the opinion of management, such matters are either adequately covered by insurance or otherwise indemnified, or are not expected, individually or in the aggregate, to result in a material, adverse effect on the Company’s financial condition. However, it is possible that the Company’s results of operations, financial position and cash flows in a particular period could be materially affected by these contingencies.

The Company accrues for loss contingencies when it is deemed probable that a loss has been incurred and that loss is estimable. If the reasonable estimate of a probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is recorded. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded and actual results may differ from these estimates. The amounts accrued are based on the full amount of the estimated loss before considering insurance proceeds and do not include an estimate for legal fees expected to be incurred in connection with the loss contingency. The Company consistently accrues legal fees expected to be incurred in connection with loss contingencies as those fees are incurred by outside counsel as a period cost.

As part of the acquisition of Arkis BioSciences Inc. (“Arkis”), the Company is required to pay the former shareholders of Arkis up to $25.5 million based on the timing of certain development milestones of $10.0 million and commercial sales milestones of $15.5 million, respectively. The Company used a probability weighted income approach to calculate the fair value of the contingent consideration that considered the possible outcomes of scenarios related to each specified milestone. The Company estimated the fair value of the contingent consideration to be $13.1 million at the acquisition date. In the first quarter of 2025, the Company paid out a development milestone related to design verification procedures for $5.0 million.

The Company assumed contingent consideration incurred by Derma Sciences, Inc. (“Derma Sciences”) related to its acquisitions of BioD, LLC and the intellectual property related to Medihoney® products. The Company accounted for the contingent liabilities by recording the fair value on the date of the acquisition based on a probability weighted income approach. The Company has already paid $33.3 million related to the aforementioned contingent liabilities. One contingent milestone remains, which relates to net sales of Medihoney products exceeding certain amounts defined in the agreement between the Company and Derma Sciences. The potential maximum undiscounted payment amounts to $3.0 million.

As part of the acquisition of ACell, the Company is required to make payments to the former shareholders of ACell up to $100 million in total for years 2022, 2023, and 2025 based on the achievement by the Company of certain revenue-based performance milestones. The Company estimated the fair value of the contingent consideration to be $23.9 million at the acquisition date. The 2022 and 2023 milestones were not achieved, leaving only one contingent milestone remaining. The Company used iterations of the Monte Carlo simulation to calculate the fair value of the contingent consideration that considered the possible outcomes of scenarios related to each specific milestone.
