Public Policy Holding Company, Inc.

We use a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability. These financial and operating metrics include Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBITDA Including M&A expense, Adjusted net income, Adjusted EPS basic, Adjusted EPS fully diluted, Organic Revenue Growth, and Adjusted Free Cash Flow which are financial measures not recognized under U.S. GAAP.

These non-GAAP financial measures are used by management to measure our operating performance, but may not be directly comparable to similar measures, such as EBITDA or Adjusted EBITDA, relied on or reported by other companies, including other companies in our industry. We believe excluding items that neither relate to the ordinary course of business nor reflect our underlying business operating performance, such as equity-based compensation, the amortization of acquired intangible assets, acquisition-related post-combination compensation and contingent consideration, gains on bargain purchase price, interest and tax enables meaningful period-to-period comparisons of our operating performance. We also use these non-GAAP financial measures when publicly providing our business outlook, for internal management purposes, and as a basis for evaluating potential acquisitions and dispositions.
