Completion of the TestEquity Merger On April 1, 2022, (the “Closing Date”), the TestEquity Merger was consummated pursuant to the TestEquity Merger Agreement. In accordance with the TestEquity Merger Agreement, Merger Sub 1 merged with and into TestEquity, with TestEquity surviving as a wholly-owned subsidiary of Lawson. TestEquity is a distributor of parts and services to the industrial, commercial, institutional and governmental electronics manufacturing and test and measurement market.

If any TestEquity Holdback Shares remain after the calculation of the first earnout opportunity, there is a second earnout opportunity based on, among other factors, the increase in TestEquity EBITDA (as defined in the TestEquity Merger Agreement) in calendar year 2022 over calendar year 2021 subject to the calculations within the TestEquity Merger Agreement.
