Supplemental Disclosure Regarding Non-GAAP Financial Information

The following tables set forth the Company’s OIBDAN for the three months ended March 31, 2018 and 2017. The Company defines OIBDAN as consolidated operating income adjusted to exclude non-cash compensation expenses, included within corporate expenses, as well as the following line items presented in its Statement of Comprehensive Loss: Depreciation and amortization; Impairment charges; and Other operating income (expense), net.

The Company uses OIBDAN, among other measures, to evaluate the Company’s operating performance. This measure is among the primary measures used by management for the planning and forecasting of future periods, as well as for measuring performance for compensation of executives and other members of management. We believe this measure is an important indicator of the Company’s operational strength and performance of its business because it provides a link between operational performance and operating income. It is also a primary measure used by management in evaluating companies as potential acquisition targets.

The Company believes the presentation of this measure is relevant and useful for investors because it allows investors to view performance in a manner similar to the method used by the Company’s management. The Company believes it helps improve investors’ ability to understand the Company’s operating performance and makes it easier to compare the Company’s results with other companies that have different capital structures or tax rates. In addition, the Company believes this measure is also among the primary measures used externally by the Company’s investors, analysts and peers in its industry for purposes of valuation and comparing the operating performance of the Company to other companies in its industry.

Since OIBDAN is not a measure calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, operating income as an indicator of operating performance and may not be comparable to similarly titled measures employed by other companies. OIBDAN is not necessarily a measure of the Company’s ability to fund its cash needs. As it excludes certain financial information compared with operating income, the most directly comparable GAAP financial measure, users of this financial information should consider the types of events and transactions which are excluded.

The other non-GAAP financial measures presented in the tables below are: (i) revenues, direct operating and SG&A expenses and OIBDAN, each excluding the effects of foreign exchange rates; (ii) revenues, direct operating and SG&A expenses and OIBDAN, each excluding the effects of foreign exchange rates and the results from outdoor business sold; (iii) revenues, excluding political advertising revenues and (iv) corporate expenses, excluding non-cash compensation expenses and effects of foreign exchange rates.

The Company presents revenues, direct operating and SG&A expenses and OIBDAN, each excluding the effects of foreign exchange rates, because management believes that viewing certain financial results without the impact of fluctuations in foreign currency rates facilitates period to period comparisons of business performance and provides useful information to investors. A significant portion of the Company’s advertising operations are conducted in foreign markets, principally Europe, the U.K. and China, and management reviews the results from its foreign operations on a constant dollar basis. Revenues, direct operating and SG&A expenses and OIBDAN, each excluding the effects of foreign exchange rates, are calculated by converting the current period’s amounts in local currency to U.S. dollars using average foreign exchange rates for the prior period.

In the third quarter of 2018, we sold our outdoor business in Canada. The Company presents revenues, direct operating and SG&A expenses and OIBDAN, each excluding the effects of foreign exchange rates and the results from the business sold, for the consolidated Company and the Company’s segments, in order to facilitate investors’ understanding of operational trends without the impact of fluctuations in foreign currency rates and without the results from the markets and businesses that were sold, as these results will not be included in the Company’s results in current and future periods.

The Company presents revenues, excluding the effects of political revenue. Due to the cyclical nature of the electoral system and the seasonality of the related political revenues, management believes presenting revenue, excluding the effects of political revenue, provides additional information to investors about the Company’s revenue growth from period to period.

Corporate expenses, excluding the effects of non-cash compensation expenses and the effects of foreign exchange rates, is presented as OIBDAN excludes non-cash compensation expenses.

Since these non-GAAP financial measures are not calculated in accordance with GAAP, they should not be considered in isolation of, or as a substitute for, the most directly comparable GAAP financial measures as an indicator of operating performance.

As required by the SEC rules, the Company provides reconciliations below to the most directly comparable amounts reported under GAAP, including (i) OIBDAN, excluding effects of foreign exchange rates and OIBDAN for each segment, to consolidated and segment operating income (loss); (ii) revenues, excluding effects of foreign exchange rates, to revenues (iii); direct operating and SG&A expenses, excluding effects of foreign exchange rates, to direct operating and SG&A expenses; (iv) revenues, excluding political advertising revenues, to revenues; (v) corporate expenses, excluding non-cash compensation expenses and effects of foreign exchange rates, to corporate expenses; (vi) consolidated and outdoor revenues, excluding effects of foreign exchange rates and results from outdoor business sold, to consolidated and outdoor revenues; (vii) consolidated and outdoor direct operating and SG&A expenses, excluding the effects of foreign exchange rates and results from outdoor business sold, to consolidated and outdoor direct operating and SG&A expenses; and (vii) consolidated and outdoor OIBDAN, excluding effects of foreign exchange rates and results from outdoor business sold, to consolidated and outdoor operating income.
