Presentation of Predecessor and Successor Financial Results
As a result of the business combination, GTY is the acquirer for accounting purposes and Bonfire, CityBase, eCivis, Open Counter, Questica, and Sherpa are the acquirees and accounting predecessor. The company’s financial statement presentation distinguishes the company’s presentations into two distinct periods, the period up to the closing date (labeled “Predecessor”) and the period including and after that date (labeled “Successor”). The merger was accounted for as a business combination using the acquisition method of accounting, and the Successor financial statements reflect a new basis of accounting that is based on the fair value of the net assets acquired.
Use of Non-GAAP Financial Measures
To supplement its condensed consolidated financial statements, which are prepared in accordance with U.S. generally accepted accounting principles, or GAAP, GTY has provided in this release certain financial measures that have not been prepared in accordance with GAAP defined as “non-GAAP financial measures,” which include (i) non-GAAP revenues, (ii) non-GAAP gross profit and non-GAAP gross margin, (iii) and non-GAAP loss from operations.
GTY’s management uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to the corresponding GAAP measures, in evaluating GTY’s ongoing operational performance and trends. However, it is important to note that particular items GTY excludes from, or includes in, its non-GAAP financial measures may differ from the items excluded from, or included in, similar non-GAAP financial measures used by other companies in the same industry. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures. A reconciliation of the non-GAAP financial measures to such GAAP financial measures has been provided in the tables included as part of this press release. In addition, as the business combination occurred on February 19, 2019, GTY believes reviewing the operating results on a pro forma basis is more useful in discussing the overall operating performance when compared to the same period in the prior year. Therefore, to compare the twelve months ended December 31, 2020 to the twelve months ended December 30, 2019, the company combined the GAAP and non-GAAP financial measures of the Predecessor period from January 1, 2019 through February 18, 2019 and the Successor period from February 19, 2019 through December 31, 2019 (“S/P Combined 2019”).
Non-GAAP Revenues. Non-GAAP revenues are defined as GAAP revenues adjusted for the impact of purchase accounting resulting from its business combination which reduced its acquired contract liabilities to fair value. The company believes that presenting non-GAAP revenues is useful to investors
