During the year ended December 31, 2023, due to a downward revision in the revenue forecast related to a contingent earn-out eligible fire retardant product acquired by the Company in May 2020 during the purchase of LaderaTECH, Inc. (“LaderaTECH”), the Company determined that the $40.7 million in carrying value of the technology underlying the contingent earn-out eligible fire retardant product is no longer recoverable. As a result, during the year ended December 31, 2023 the Company recorded an impairment of $40.7 million in the accompanying consolidated statements of operations and comprehensive (loss) income.
