Exhibit 99.1

ENTERCOM COMMUNICATIONS CORP.

REPORTS FIRST QUARTER RESULTS

Philadelphia, PA—Entercom Communications (NYSE: ETM) today reported financial results for the quarter ended March 31, 2018.

First Quarter Highlights

David J. Field, President and Chief Executive Officer, stated: “Since closing on our merger in November, we have moved quickly to implement rapid change and have made good progress on our various integration, synergy and transformation goals. We have built a terrific leadership team and are driving strong ratings growth and launching a number of revenue-driving initiatives to capitalize on our scale and compete far more effectively against other media for a larger share of ad spending. Earlier today, we announced the launch of the Entercom Audio Network which will enable us to use our scale to participate directly in the $1 billion network radio market. Our first quarter financial results were adversely affected by soft general local advertising conditions and a number of temporary factors, most notably the exclusion of $12 million in revenue due to financial issues at USTN. As these temporary factors abate and our growth initiatives take hold, we look forward to driving meaningful sustainable growth as we capitalize on the compelling brands, assets and capabilities of this exciting, emerging company.”

Additional Information

Today the Company announced the launch of the Entercom Audio Network which will enable the company to capitalize on its scale and reach to participate directly in the $1 billion network radio business. Launching on July 1, 2018, the network will cover close to 90% of people 12+ in the top 50 markets.

In April, the Company entered into a new agreement with United States Traffic Network (“USTN”) which sells short duration advertising (sponsored traffic reports) and provides guaranteed revenue to the Company. USTN completed its separation from its former corporate parent and has moved quickly to establish a solid new business model.

As of March 31, 2018, the Company had outstanding $1,452 million of senior debt under its credit facilities and $400 million in senior notes (both amounts exclude unamortized premium from purchase price accounting). In addition, the Company had $34.8 million in cash on hand.

Adjusted Net Income (Loss) Per Share - Diluted includes any dilutive equivalent shares when not anti-dilutive. Convertible Preferred Stock is treated as if it never converted for the purposes of Adjusted Net Income (Loss) Per Share - Diluted.

Non-GAAP Financial Measures

It is important to note that station operating income, station expense, corporate expense, same station net revenues, Adjusted EBITDA, Pro Forma Adjusted EBITDA, Adjusted Net Income, Adjusted Net Income (Loss) Per Share - Diluted and Adjusted 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 (Loss) and Adjusted Net Income (Loss) Per Share - Diluted). The adjustments exclude gain/loss on sale of assets, derivative instruments, and investments; non-cash compensation expense, other income, impairment loss, merger and acquisition costs, other expenses related to the refinancing, and gain/loss on early extinguishment of debt and non-recurring expenses recognized for restructuring charges or similar costs, including transition and integration costs. For purposes of comparability, income taxes for 2018 and 2017 are reflected at the expected federal and state income tax rate of 30% and 40%, respectively, without adjustment for discrete tax adjustments.

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 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.
