Entercom Communications Corp.

Reports First Quarter Results

(Bala Cynwyd, Pa. May 4, 2015) Entercom Communications Corp. (NYSE: ETM) today reported financial results for the quarter ended March 31, 2015.

First Quarter Highlights

David J. Field, President and Chief Executive Officer, stated: “Entercom’s first quarter revenues were up slightly over the prior year as significant market share gains were offset by sluggish advertising conditions. We are very much looking forward to completing our acquisition of Lincoln Financial Media and adding its terrific new markets and brands to our lineup. In the meantime, we are complying with the Department of Justice’s review of this transaction which would provide us with a second-place position with a 32% pro-forma share of the Denver radio market.”

Additional Information

In December, the Company announced the acquisition of Lincoln Financial Media from Lincoln Financial Group. On February 17, the Company received a second request from the Department of Justice for information relating to this transaction and the Company to which the Company is currently responding. The Company incurred approximately $1.7 million in expenses related to the transaction in the quarter.

The Company reduced its outstanding debt by $15.7 million (net of cash) during the quarter. As of March 31, 2015 the Company had $479.3 million of senior debt and senior notes and $46.6 million in cash.

Exhibit 99.1 - Page 2

Free cash flow consists of operating income (loss): (i) plus depreciation and amortization, net (gain) loss on sale or disposal of assets; non-cash compensation expense (which is otherwise included in station operating expenses and corporate general and administrative expenses), impairment loss; merger and acquisition costs; and (ii) less net interest expense (excluding amortization of deferred financing costs), taxes paid and capital expenditures.

Adjusted net income consists of net income (loss) adjusted to exclude: (i) income taxes (benefit) as reported; (ii) gain/loss on sale of assets, derivative instruments and investments; (iii) non-cash compensation expense; (iv) other income; (v) impairment loss; (vi) merger and acquisition costs; and (vii) gain/loss on early extinguishment of debt. For purposes of comparability, income taxes are reflected at the expected statutory federal and state income tax rate of 42% without discrete items of tax.

Adjusted net income per share includes any dilutive equivalent shares when not anti-dilutive.

Same station is computed by comparing the performance of stations operated by the Company throughout the relevant period to the comparable performance in the prior year’s corresponding period (excluding non-cash compensation expense). Any acquisition or disposition of radio stations not deemed to be material by management is ignored for the purpose of computing this data. There were no material acquisitions during the periods presented in the tables below.

Non-GAAP Financial Measures

It is important to note that station operating income, station expense, corporate expense, same station net revenues, same station expenses, same station operating income, adjusted EBITDA, adjusted net income, adjusted net income per share and free cash flow are not measures of performance or liquidity calculated in accordance with generally accepted accounting principles (“GAAP”). Management believes that these measures are useful as a way to evaluate the Company and the means for management to evaluate our radio stations’ performance and operations. Management believes that these measures are useful to an investor in evaluating our performance because they are widely used in the broadcast industry as a measure of a radio company’s operating performance.

Certain adjusted non-GAAP financial measures are presented in this release (e.g., adjusted net income and adjusted net income per share). The adjustments exclude gain/loss on sale of assets, derivative instruments, and investments; non-cash compensation expense, other income, impairment loss and gain/loss on early extinguishment of debt. Management believes these adjusted non-GAAP measures provide useful information to Management and investors by excluding certain income, expenses and gains and losses that may not be indicative of the Company’s core operating and financial results. Similarly, Management believes these adjusted measures are a useful performance measure because certain items included in the calculation of net income (loss) may either mask or exaggerate trends in the Company’s ongoing operating performance. Further, the reconciliations corresponding to these adjusted measures, by identifying the individual adjustments, provide a useful mechanism for investors to consider these adjusted measures with some or all of the identified adjustments.

Management uses these non-GAAP financial measures on an ongoing basis to help track and assess the Company’s financial performance. You, however, should not consider non-GAAP

Exhibit 99.1 - Page 3

measures in isolation or as substitutes for net income (loss), operating income, or any other measure for determining our operating performance that is calculated in accordance with generally accepted accounting principles. These non-GAAP measures are not necessarily comparable to similarly titled measures employed by other companies. The accompanying financial tables provide reconciliations to the nearest GAAP measure of all non-GAAP measures provided in this release.
