First Quarter 2015 Results

After adjustment for a $49 million impact from movements in foreign exchange rates, consolidated operating expenses increased 5% in the first quarter primarily due to an increase in variable costs and compensation expense associated with higher revenue. On a reported basis, consolidated operating expenses decreased $24 million or 5%.

After adjusting for movements in foreign exchange rates, the Company’s OIBDAN¹ was up 11% in the first quarter 2015 compared to the same period of 2014. Included in the 2015 first quarter OIBDAN¹ were $1 million of operating expenses and $3 million of corporate expenses associated with the Company’s strategic revenue and efficiency initiatives, in line with such expenses in the prior year. On a reported basis, OIBDAN¹ was up 7% to $98 million for the first quarter compared to the same period in 2014.

The Company’s consolidated net loss totaled $34 million in the first quarter of 2015 compared to $97 million in the same period of 2014. The decrease was primarily due to foreign currency gains recognized in connection with intercompany notes payable denominated in foreign currencies and an income tax benefit recorded in the first quarter 2015, compared to income tax expense recorded in the same period in 2014.

TABLE 3 - Total Debt

At March 31, 2015 and December 31, 2014, Clear Channel Outdoor Holdings, Inc. had a total net debt of:

The current portion of long-term debt was $2.7 million and $3.5 million as of March 31, 2015 and December 31, 2014, respectively.

Liquidity and Financial Position

For the three months ended March 31, 2015, cash flow provided by operating activities was $10 million, cash flow used for investing activities totaled $41 million, cash flow provided by financing activities was $58 million, and there was a $6 million impact from movements in foreign exchange rates on cash. The net increase in cash was $21 million.

Capital expenditures for the three months ended March 31, 2015 were approximately $42 million compared to $39 million for the same period in 2014.

The consolidated leverage ratio, defined as total debt divided by EBITDA (as defined by the Clear Channel Worldwide Holdings (“CCWH”) Senior Notes indentures) for the preceding four quarters was 6.4:1 at March 31, 2015, and the senior leverage ratio, defined as senior debt divided by EBITDA (as defined by the CCWH Senior Notes indentures) for the preceding four quarters was 3.6:1 at March 31, 2015. As required by the definition of EBITDA in the CCWH Senior Notes indentures, our EBITDA for the preceding four quarters of $767 million is calculated as operating income (loss) before depreciation, amortization, impairment charges and other operating income (expense), net, plus share-based compensation, and is further adjusted for the following items: (i) costs incurred in connection with the closure and/or consolidation of facilities, retention charges, consulting fees and other permitted activities; (ii) extraordinary, non-recurring or unusual gains or losses or expenses and severance; (iii) non-cash charges; (iv) cash received from nonconsolidated affiliates; and (v) various other items.

The following table reflects a reconciliation of consolidated EBITDA (as defined by the CCWH Senior Notes indentures) to operating income and net cash provided by operating activities for the four quarters ended March 31, 2015:

Supplemental Disclosure Regarding Non-GAAP Financial Information

The following tables set forth the Company’s OIBDAN for the three months ended March 31, 2015 and 2014. The Company defines OIBDAN as consolidated net income (loss) adjusted to exclude non-cash compensation expenses and amortization of deferred system implementation costs as well as the following line items presented in its Statement of Operations: Income tax benefit (expense); Other income (expense), net; Equity in earnings (loss) of nonconsolidated affiliates; Interest expense; Interest income on Due from iHeartCommunications, Inc.; Other operating income, net; Depreciation and amortization; and Impairment charges.

The Company uses OIBDAN, among other things, 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 profitability and net 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, equity compensation 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, net 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 and net income (loss), the most directly comparable GAAP financial measures, users of this financial information should consider the types of events and transactions which are excluded.

In addition, because a significant portion of the Company’s advertising operations are conducted in foreign markets, principally Europe, the U.K. and China, management reviews the operating results from its foreign operations on a constant dollar basis. A constant dollar basis (in which a foreign currency adjustment is made to show the 2015 actual foreign revenues, expenses and OIBDAN at average 2014 foreign exchange rates) allows for comparison of operations independent of foreign exchange rate movements.

As required by the SEC, the Company provides reconciliations below to the most directly comparable amounts reported under GAAP, including (i) OIBDAN for each segment to consolidated operating income (loss); (ii) Revenues excluding the effects of foreign exchange to revenues; (iii) Expenses excluding the effects of foreign exchange to expenses; (iv) OIBDAN excluding the effects of foreign exchange to OIBDAN; (v) Corporate expenses excluding non-cash compensation expenses to Corporate expenses; and (vi) OIBDAN to net income (loss).
