FOR IMMEDIATE RELEASE

SBA COMMUNICATIONS CORPORATION REPORTS 2^nd QUARTER 2013 RESULTS;

PROVIDES 3^rd QUARTER AND UPDATED 2013 OUTLOOK

Boca Raton, Florida, August 1, 2013

SBA Communications Corporation (Nasdaq: SBAC) (“SBA” or the “Company”) today reported results for the quarter ended June 30, 2013. Highlights of the results include:

Second quarter over year earlier period:

“The second quarter was another strong one for SBA,” commented Jeff Stoops, President and CEO. “Our domestic customers continue to stay very busy, with both high levels of 4G amendment activity on existing macro sites and an increasing amount of new macro site deployment activity. Activity in our international markets was strong as well. Based on our existing backlogs, we expect continued strength in both our leasing and services segments for the remainder of 2013 and into 2014. We expect our portfolio growth will accelerate materially in the second half of 2013, primarily as a result of our recently announced Oi transaction in Brazil, which upon its anticipated closing later this year will result in us once again surpassing our annual portfolio growth goals. We expect the combination of strong continued customer activity and material portfolio growth will allow us to finish 2013 with, and position 2014 for, material growth in site leasing revenue, adjusted EBITDA, AFFO and AFFO per share.”

Subsequent to the second quarter of 2013, the Company acquired 5 towers and related assets and liabilities and the rights to manage 3 additional communication sites for an aggregate consideration of $5.4 million in cash. In addition to the Company’s previously announced agreement to purchase the exclusive use rights for 2,113 towers in Brazil from Oi SA for approximately R$686.7 million, the Company has agreed to purchase in the U.S. and internationally 299 towers and the rights to manage 5 additional communication sites for an aggregate amount of $162.1 million. The Company anticipates that these acquisitions will be consummated by the end of the fourth quarter of 2013.

Financing Activities and Liquidity

On April 18, 2013, the Company, through its existing SBA Tower Trust, sold $1.33 billion in Secured Tower Revenue Securities (the “2013 Tower Securities”). The 2013 Tower Securities have a blended interest rate of 3.218% and a weighted average life through the anticipated repayment date of 7.2 years. The net proceeds from this offering were used to repay the $100.0 million outstanding balance under the Company’s Revolving Credit facility, to repay $500.0 million of Term Loans under the Company’s Senior Credit Agreement, and to satisfy the unhedged obligations in connection with the Company’s 1.875% Convertible Senior Notes due 2013.

SBA ended the second quarter with $5.7 billion of total debt, $231.2 million of cash and cash equivalents, short-term restricted cash, and short-term investments, and $5.5 billion of Net Debt (as defined below). SBA’s Net Debt and Net Secured Debt to Annualized Adjusted EBITDA Leverage Ratios were 7.0x and 4.4x, respectively.

As of June 30, 2013, the Company had no amounts outstanding under the Revolving Credit Facility, and the amount available under the facility was $770.0 million, subject to compliance with specified financial ratios and the satisfaction of other customary conditions to borrowing.

During the second quarter, SBA spent $23.6 million to early settle a portion of the outstanding warrants scheduled to mature during the third and fourth quarter. There were approximately 2.7 million shares underlying the settled warrants, or approximately 20% of the total outstanding warrants.

During the second quarter, SBA did not repurchase any shares of its Class A common stock. The Company currently has $150.0 million of repurchase authorization remaining under its existing $300.0 million stock repurchase program.

Outlook

The Company is providing its third quarter 2013 Outlook and updating its Full Year 2013 Outlook for anticipated results. The Outlook provided is based on a number of assumptions that the Company believes are reasonable at the time of this press release. Information regarding potential risks that could cause the actual results to differ from these forward-looking statements is set forth below and in the Company’s filings with the Securities and Exchange Commission.

The Company’s Full Year 2013 Outlook for discretionary cash capital expenditures assumes the acquisition of only those tower assets under contract at the time of this press release, including the Oi acquisition. The substantial majority of these acquisitions are assumed to close at the end of the year. The Company intends to spend additional capital in 2013 on acquiring revenue producing assets not yet identified or under contract, the impact of which is not reflected in the 2013 guidance. The Company’s 2013 Outlook includes new tower builds in the U.S. and internationally of 380 to 400 towers. Finally, the Company’s Outlook also assumes an average foreign currency exchange rate of 2.28 Brazilian Reais to 1.0 U.S. Dollar for the third and fourth quarters of 2013.

Non-GAAP Financial Measures

The press release contains non-GAAP financial measures, including (i) Site Leasing Segment Operating Profit, Site Development Segment Operating Profit, and Segment Operating Profit Margin, (ii) Tower Cash Flow and Tower Cash Flow Margin, (iii) Adjusted EBITDA, Annualized Adjusted EBITDA, and Adjusted EBITDA Margin, (iv) Net Debt, Net Secured Debt, Leverage Ratio, and Secured Leverage Ratio (collectively, our “Non-GAAP Debt Measures”), and (v) Funds from Operations (“FFO”), Adjusted Funds from Operations (“AFFO”), and AFFO per share.

We have included these non-GAAP financial measures because we believe that they provide investors additional tools in understanding our financial performance and condition. Specifically, we believe that:

(1) Segment Operating Profit is an indicator of the operating performance of our site leasing and site development segments;

(2) Tower Cash Flow is an indicator of the performance of our site leasing operations;

(3) Adjusted EBITDA, FFO, AFFO, and AFFO per share are useful indicators of the financial performance of our core businesses; and

(4) Our Non-GAAP Debt Measures provide investors a more complete understanding of our net debt and leverage position as they include the full principal amount of our debt which will be due at maturity.

In addition, Tower Cash Flow, Adjusted EBITDA, and our Non-GAAP Debt Measures are components of the calculations used by our lenders to determine compliance with certain covenants under our Senior Credit Agreement, 8.25% Notes, 5.625% Notes, and 5.75% Notes. These non-GAAP financial measures are not intended to be an alternative to any of the financial measures provided in our results of operations or our balance sheet as determined in accordance with GAAP.

We believe that FFO, AFFO, and AFFO per share, which are also being used by American Tower Corporation and Crown Castle International (our two public company peers in the tower industry), provide investors useful indicators of the financial performance of our core business and permit investors an additional tool to evaluate the performance of our business against those of our two principal competitors. FFO, AFFO and AFFO per share are not necessarily indicative of the operating results that would have been achieved had we converted to a REIT. In addition, our FFO, AFFO, and AFFO per share may not be comparable to those reported in accordance with National Association of Real Estate Investment Trusts or by the other tower companies as the calculation of these non-GAAP measures requires us to estimate the impact had we converted to a REIT, including estimates of the tax provision adjustment to reflect our estimate of our cash taxes had we been a REIT.
