Reconciliation of Non-GAAP Financial Measures 1. Includes costs associated with forming i3 Verticals, Inc. and other expenses directly related to the certain transactions as part of any offering. 2. Non-cash change in fair value of contingent consideration reflects the changes in management’s estimates of future cash consideration to be paid in connection with prior acquisitions from the amount estimated as of the later of the most recent balance sheet date forming the beginning of the income statement period or the original estimates made at the closing of the applicable acquisition. 3. Non-cash change in warrant liability reflects the fair value change in certain warrants for our common units associated with our mezzanine notes in the aggregate principal amount of $10.5 million. These warrants are accounted for as liabilities on our consolidated balance sheets. 4. Equity-based compensation expense was not relevant during the three months ended March 31, 2018 or 2017.
