As additional consideration in acquisition of Environmental Integrated Solution (“EIS”), the former owners are entitled to earnout payments based upon a multiple of specified financial results through December 31, 2021. Based on projections at the acquisition date, the Company estimated the fair value of the earnout to be $0.6 million. During 2020 and 2021, the Company increased the earnout based on the estimated fair value at the end of the year. The fair value adjustment is recorded as expense in “Amortization and earnout expenses” on the Consolidated Statements of Income. The changes in fair value were a result of EIS performing above initial acquisition operational expectations. See Note 15 for further discussion of the EIS acquisition.
