Supplemental Disclosure Regarding Non-GAAP Financial Information

We use supplemental measures of our performance, which are derived from our consolidated financial information, but which are not presented in our consolidated financial statements prepared in accordance with GAAP. Adjusted EBITDA is the primary financial performance measure used by management to evaluate our business and monitor ongoing results of operations. Adjusted EBITDA is defined as income before depreciation and amortization, stock-based compensation, interest (income) expense, income taxes, acquisition, restructuring and integration costs, foreign exchange loss (gain), net, asset impairments, and other one-time, non-recurring costs. Adjusted EBITDA margin represents the adjusted EBITDA for the applicable period divided by the revenue for that period presented in accordance with GAAP.

We use non-GAAP financial measures to supplement financial information presented on a GAAP basis. We believe that excluding certain items from our GAAP results allows management to better understand our consolidated financial performance from period to period and better project our future consolidated financial performance as forecasts are developed at a level of detail different from that used to prepare GAAP-based financial measures. Moreover, we believe these non-GAAP financial measures provide our shareholders with useful information to help them evaluate our operating results by facilitating an enhanced understanding of our operating performance and enabling them to make more meaningful period-to-period comparisons. Although we believe these measures are useful to investors and analysts for the same reasons they are useful to management, as discussed below, these measures are not a substitute for, or superior to, U.S. GAAP financial measures or disclosures. Our non-GAAP financial measures may not be comparable to similarly titled measures of other companies. Other companies, including companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

Reconciliations of historical adjusted EBITDA to its most directly comparable GAAP financial measure, net income/loss, are presented below. We encourage you to review the reconciliations in conjunction with the presentation of the non-GAAP financial measures for each of the periods presented. In future fiscal periods, we may exclude such items and may incur income and expenses similar to these excluded items.

Forward-Looking Statements

This earnings press release contains forward-looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact included in this press release are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance, including guidance, and business, including pipeline and industry trends. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as "anticipate," "estimate," "expect," "project," "plan," "intend," "believe," "may," "will," "should," "can have," "likely," and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. For example, all statements we make relating to our current expectations relating to the acquisition of the company by Novacap (the "Merger") and the transactions contemplated by the related Merger Agreement, our estimated and projected costs, profitability, expenditures, cash flows, growth rates and financial results or our plans and objectives for future operations, growth initiatives or strategies are forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expected, including: (i) the risk that the Merger may not be completed in a timely manner or at all, which may adversely affect our business and the price of our common stock; (ii) the timing to consummate the Merger, or the occurrence of any event, change, or other circumstances that could give rise to the termination of the Merger Agreement, including circumstances requiring a party to pay the other party a termination fee pursuant to the Merger Agreement; (iii) the failure to satisfy the conditions to the consummation of the Merger, and the other transactions contemplated thereby; (iv) the risk that a governmental or regulatory approval that may be required for the Merger is not obtained or is obtained subject to conditions that are not anticipated; (v) the effect of the pendency of the Merger on our business relationships, operating results and business generally; (vi) certain restrictions during the pendency of the Merger that may impact our ability to pursue certain business opportunities or strategic transactions; (vii) risks that the Merger disrupts current plans and operations; (viii) risks related to diverting management's attention from our ongoing business operations; (ix) the outcome of any legal proceedings that may be instituted against the parties to the Merger Agreement or their respective directors, managers or officers, including the effects of any outcomes related thereto; (x) our ability to retain, hire and integrate skilled personnel, and maintain relationships with key business partners and customers, and others with whom we do business, in light of the proposed Merger; (xi) unexpected costs, charges or expenses resulting from the Merger; (xii) the adverse effect on our business, operating results, financial condition, and prospects from various macroeconomic factors, including instability in geopolitical or market conditions; (xiii) our failure to innovate or make the right investment decisions; (xiv) our ability to provide digital or cross-platform analytics; (xv) our failure to maintain or achieve industry accreditation standards; (xvi) our dependence on integrations with advertising platforms, demand side providers ("DSPs") and proprietary platforms that we do not control; (xvii) our ability to compete successfully with our current or future competitors in an intensely competitive market; (xviii) our ability to sustain our profitability and revenue growth rate; (xix) our dependence on the overall demand for advertising; and (xx) other factors disclosed in our filings with the SEC. Given these factors, as well as other variables that may affect our operating results, you should not rely on forward-looking statements, assume that past financial performance will be a reliable indicator of future performance, or use historical trends to anticipate results or trends in future periods.

We derive many of our forward-looking statements from our operating budgets and forecasts, which are based on many detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. The forward-looking statements included in this press release are made only as of the date hereof. We undertake no obligation to update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
