FOR IMMEDIATE RELEASE

SBA COMMUNICATIONS CORPORATION REPORTS 1^st QUARTER 2014 RESULTS;

PROVIDES 2^nd QUARTER AND UPDATED FULL YEAR 2014 OUTLOOK

Boca Raton, Florida, May 1, 2014

SBA Communications Corporation (Nasdaq: SBAC) (“SBA” or the “Company”) today reported results for the quarter ended March 31, 2014. Highlights of the results include:

First quarter over year earlier period:

“We had an excellent first quarter and expect another good year in 2014” commented Jeffrey A. Stoops, President and Chief Executive Officer. “Among many highlights in our first quarter, we are particularly pleased with our expense performance which produced industry leading Tower Cash Flow and Adjusted EBITDA margin results. Year-to-date leasing activity and current backlogs evidence very strong customer activity in all of our markets. As a result, we are able to make sizeable increases in our 2014 Outlook, which increases are driven almost entirely by organic activity. With our recently closed acquisition of 2,007 sites from Oi, Brazil now joins our U.S. and other markets as fully scaled and capable operations, well-positioned to continue to participate in the projected growth of wireless in their respective regions. Our balance sheet and liquidity positions are both sound, and give us plenty of resources to pursue additional quality portfolio growth opportunities. We believe 2014 will be another year of material growth in AFFO per share for SBA.”

SBA also built 57 towers during the first quarter of 2014. As of March 31, 2014, SBA owned or operated 22,263 communication sites, 15,034 of which are located in the United States and its territories, and 7,229 of which are located internationally. In addition, the Company spent $9.3 million to purchase land and easements and to extend lease terms with respect to land underlying its towers. Total cash capital expenditures for the first quarter of 2014 were $947.5 million, consisting of $4.7 million of non-discretionary cash capital expenditures (tower maintenance and general corporate) and $942.8 million of discretionary cash capital expenditures net of currency hedging benefits (new tower builds, tower augmentations, acquisitions and related earn-outs, purchasing land and easements, and capital expenditures associated with the purchase of a new headquarters building).

Subsequent to the first quarter of 2014, the Company acquired 12 towers and related assets and liabilities for aggregate consideration of $8.9 million in cash. The Company has agreed to purchase 59 towers for an aggregate amount of $35.5 million. The Company anticipates that these acquisitions will be consummated by the end of the third quarter of 2014.

Financing Activities and Liquidity

SBA ended the first quarter with $6.9 billion of total debt, $363.2 million of cash and cash equivalents, short-term restricted cash, and short-term investments, and $6.5 billion of Net Debt (as defined below). SBA’s Net Debt and Net Secured Debt to Annualized Adjusted EBITDA Leverage Ratios were 7.2x and 5.0x, respectively.

During the first quarter of 2014, the Company, through its wholly owned subsidiary, SBA Senior Finance II LLC, obtained a new senior secured Term Loan with an initial aggregate principal amount of $1.5 billion that was issued at 99.75% of par value and matures on March 24, 2021 (“2014 Term Loan B”). Net proceeds from the 2014 Term Loan B were used to (1) repay in full the remaining $180.5 million balance of the 2011 Term Loan B, (2) repay in full the remaining $110.0 million balance of the 2012-2 Term Loan B, (3) repay the $390.0 million outstanding balance under the Company’s Revolving Credit Facility, and (4) pay the cash consideration in connection with the Oi Acquisition.

Effective March 17, 2014, the Company elected to settle the principal amount of any conversions on its 4.0% Convertible Senior Notes due 2014 (“4.0% Notes”) in cash and any additional conversion consideration at the conversion rate then applicable in shares of its Class A common stock. Concurrently with the settlement of any converted 4.0% Notes, SBA will settle the associated convertible note hedges and receive an equal number of shares to those issued to the noteholders. As a result, SBA’s outstanding share count will not be impacted by the early conversion of these notes under the current settlement election. The Company received conversion notices totaling $259,000 of principal during the first quarter of 2014 and conversion notices totaling $121.3 million of principal subsequent to the end of the first quarter, all of which will settle in the second quarter of 2014.

During the first 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 second quarter 2014 Outlook and updating its Full Year 2014 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 2014 Outlook assumes approximately $56.7 million of non-cash straight-line leasing revenue. The 2014 Outlook for site leasing revenue, Tower Cash Flow, Adjusted EBITDA and AFFO includes an assumed negative impact of $16 million associated with iDEN lease terminations, which from a timing perspective have been assumed to occur on the basis least favorable to SBA pursuant to previously negotiated contractual rights. The 2014 Outlook assumes the acquisitions of only those communication sites under contract at the time of this press release. The Company intends to spend additional capital in 2014 on acquiring revenue producing assets not yet identified or under contract, the impact of which is not reflected in the 2014 guidance. The Company’s Full Year 2014 Outlook includes new tower builds in the U.S. and internationally of 400 to 420 towers. The Full Year 2014 Outlook also contemplates approximately $1.3 billion of new financing during 2014 at an estimated annual interest rate of 4.0% with proceeds being used to (i) call the Company’s 8.25% Senior Notes in August 2014, and (ii) settle for cash all of the obligations under the Company’s 4.0% Convertible Senior Notes due October 1, 2014 and the related warrants upon maturity. Finally, the Company’s Outlook also assumes an average foreign currency exchange rate of 2.30 Brazilian Reais to 1.0 U.S. Dollar for the second, third, and fourth quarters of 2014.

Communication Site Portfolio Summary

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) Cash Site Leasing Revenue; (iii) Tower Cash Flow and Tower Cash Flow Margin; (iv) Adjusted EBITDA, Annualized Adjusted EBITDA, and Adjusted EBITDA Margin; (v) Net Debt, Net Secured Debt, Leverage Ratio, and Secured Leverage Ratio (collectively, our “Non-GAAP Debt Measures”); and (vi) 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) Cash Site Leasing Revenue and Tower Cash Flow are indicators 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, Total 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 communication site 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 communication site 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.
