CUMULUS MEDIA INC.

Cumulus Reports First Quarter 2013 Results

ATLANTA, GA – May 7, 2013: Cumulus Media Inc. (NASDAQ: CMLS) (the “Company,” “we,” “us,” or “our”) today reported financial results for the quarter ended March 31, 2013.

Lew Dickey, Chairman & CEO stated, “With the integration and turnaround of the Citadel assets now largely behind us, we are investing in several key content initiatives to drive growth beginning in the back half of this year and accelerating into 2014. We will post positive year-to-date revenue growth through May and expect our investments in CBS Sports Radio, Traffic, Nash and SweetJack to contribute meaningfully to our cash flow beginning in Q4 of this year.”

Financial highlights are as follows (in thousands, except percentages) (footnotes follow):

Three Months Ended March 31, 2013 Compared to Three Months Ended March 31, 2012

Net Revenues

Net revenues for the three months ended March 31, 2013 decreased $3.1 million, or 1.3%, to $232.9 million, compared to $236.0 million for the three months ended March 31, 2012. This decrease was attributable to lower political revenues and general lower advertising spending in some of our markets.

Direct Operating Expenses, Excluding Depreciation and Amortization

Direct operating expenses for the three months ended March 31, 2013 increased $10.6 million, or 6.9%, to $164.2 million, compared to $153.6 million for the three months ended March 31, 2012. The increase was primarily attributable to a $1.0 million increase in sales salaries, a $1.6 million increase in Arbitron fees and a $4.9 million increase in expense at our network division as we invest in various content initiatives.

Corporate, General and Administrative Expenses, Including Stock-based Compensation Expenses

Corporate general and administrative expenses, including stock-based compensation expense, for the three months ended March 31, 2013 decreased $2.8 million, or 16.9%, to $13.9 million, compared to $16.7 million for the three months ended March 31, 2012. The decrease was primarily due to a decrease in stock-based compensation expense of $4.3 million, partially offset by a $1.2 million increase in acquisition related costs. Acquisition related costs for the three months ended March 31, 2013 included exit costs associated with a lease for vacated Citadel office space.

Interest Expense, net

Total interest expense, net of interest income, for the three months ended March 31, 2013 decreased $6.5 million, or 12.9%, to $44.3 million compared to $50.8 million for the three months ended March 31, 2012. Interest expense associated with outstanding debt decreased by $6.5 million to $41.5 million as compared to $48.0 million in the prior year period. Interest expense decreased due to a lower average amount of indebtedness outstanding as a result of principal repayments and a lower weighted average cost of debt.

Capital Expenditures

Capital expenditures for the three months ended March 31, 2013 totaled $2.0 million which represented routine capital expenditures. Capital expenditures during the three months ended March 31, 2012 were $1.1 million.

Earnings (Loss) Per Share

Basic earnings (loss) per share (“EPS”) is calculated for the three months ended March 31, 2013 by dividing the loss from continuing operations of $8.9 million adjusted for dividends declared on preferred stock of $2.7 million and the accretion of redeemable preferred stock of $1.0 million by the weighted average number of shares of common stock outstanding during the period, which was 174,748,001. Diluted EPS for the three months ended March 31, 2013 was calculated in the same manner as basic EPS. Potentially dilutive equivalent shares outstanding for the three months ended March 31, 2013 excluded from the computation of diluted EPS consisted of approximately 39.8 million shares of common stock issuable on exercise of underlying outstanding stock options and certain warrants.

Non-GAAP Financial Measures and Definitions

We utilize certain financial measures that are not prepared or calculated in accordance with GAAP to assess our financial performance and profitability. The non-GAAP financial measures used in this release are Adjusted EBITDA and free cash flow.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) before any non-operating expenses, including net interest expense, depreciation and amortization, stock-based compensation expense, gain or loss on exchange or sale of assets or stations (if any), any realized gain or loss on derivative instruments, any impairment of intangible assets and goodwill, local marketing agreement (“LMA”) fees, acquisition-related costs and franchise taxes.

Adjusted EBITDA is the financial metric utilized by management to analyze the cash flow generated by our business. This measure isolates the amount of income generated by our radio stations after the incurrence of corporate, general and administrative expenses. Management also uses this measure to determine the contribution of our radio station portfolio, including the corporate resources employed to manage the portfolio, to the funding of our other operating expenses and to the funding of debt service and acquisitions. In addition, Adjusted EBITDA is a key metric for purposes of calculating and determining our compliance with certain covenants contained in our first lien credit facility.

In deriving this measure, management excludes depreciation, amortization and stock-based compensation expense from the measure, as these do not represent cash payments for activities directly related to the operation of the radio stations. In addition, we exclude LMA fees from our calculation of Adjusted EBITDA, even though such fees require a cash settlement, because they are excluded from the definition of Adjusted EBITDA contained in our first lien credit facility. Management excludes any gain or loss on the exchange or sale of assets or radio stations as they do not represent a cash transaction. Management also excludes any realized gain or loss on derivative instruments as they do not represent a cash transaction nor are they associated with radio station operations. Interest expense, net of interest income, income tax (benefit) expense including franchise taxes, and expenses relating to acquisitions are also excluded from the calculation of Adjusted EBITDA as they are not directly related to the operation of radio stations. Management excludes any impairment of goodwill and intangible assets as they do not require a cash outlay. Management believes that Adjusted EBITDA, although not a measure that is calculated in accordance with GAAP, nevertheless is commonly employed by the investment community as a measure for determining the market value of a radio company. Management has also observed that Adjusted EBITDA is routinely employed to evaluate and negotiate the potential purchase price for radio broadcasting companies and is a key metric for purposes of calculating and determining compliance with certain covenants in our first lien credit facility. Given the relevance to our overall value, management believes that investors consider the metric to be extremely useful.

Adjusted EBITDA should not be considered in isolation of, or as a substitute for, net income, operating income, cash flows from operating activities or any other measure for determining our operating performance or liquidity that is calculated in accordance with GAAP.

A quantitative reconciliation of Adjusted EBITDA to net (loss) income, the most directly comparable financial measure calculated and presented in accordance with GAAP, is provided under “Reconciliation of Non-GAAP Financial Measures to Most Directly Comparable GAAP Measures” below.

Free Cash Flow

Free cash flow is also utilized by management to analyze the cash generated by our business. Free cash flow measures the amount of cash generated during the applicable period that could be used to fund acquisitions or other growth opportunities or for reinvestment in our business, after funding station and corporate, general and administrative expenses (excluding transaction costs), debt service, income taxes, and capital expenditures.

We define free cash flow as net income (loss) before any non-operating expenses, including net interest expense, stock-based compensation expense, depreciation and amortization, gain or loss on the exchange or sale of assets or stations (if any), and any realized gain or loss on derivative instruments, any impairment of intangible assets and goodwill, net of interest expense (excluding any non-cash charges or credits for changes in values of swaps and amortization of debt issuance costs), income taxes paid and capital expenditures.

Management excludes depreciation and amortization, any gain or loss on the exchange or sale of assets or stations, any realized gain or loss on derivative instruments or impairment of intangible assets and goodwill and other non-cash expenses, including stock-based compensation, from net income (loss) as they do not represent cash transactions. Management deducts payments for debt service, income taxes and capital expenditures since these represent amounts that are consistently necessary for our continuing operations, in order to arrive at free cash flow available for growth opportunities or reinvestment in our business.

Management believes that free cash flow, although not a measure that is prepared or calculated in accordance with GAAP, is commonly employed by the investment community to evaluate a company’s ability to pay down debt, pay dividends, repurchase stock and/or facilitate the further growth of a company through acquisition or internal development. Management further believes that free cash flow is also utilized by investors as a measure in determining the market value of a radio company.

Free cash flow should not be considered in isolation of or as a substitute for net income, operating income, cash flows from operating activities or any other measure for determining our operating performance or liquidity that is calculated in accordance with GAAP. In addition, because free cash flow is not calculated or presented in accordance with GAAP, it may not be calculated or presented comparably to similarly titled measures used by other companies, and thus comparability may be limited. A quantitative reconciliation of free cash flow to net loss calculated in accordance with GAAP is provided below.
