FOR IMMEDIATE RELEASE

SBA COMMUNICATIONS CORPORATION REPORTS 4^th QUARTER 2012 RESULTS;

PROVIDES 1^st QUARTER, AND UPDATED FULL YEAR 2013 OUTLOOK

Boca Raton, Florida, February 21, 2013

SBA Communications Corporation (Nasdaq:SBAC) (“SBA” or the “Company”) today reported results for the quarter ended December 31, 2012. Highlights of the results include:

“The fourth quarter was a very strong finish to a remarkable year for SBA”, commented Jeff Stoops, President and CEO. “We produced exceptional year over year growth in all key metrics, including Adjusted EBITDA and AFFO per share. Domestic customer activity in the fourth quarter was the highest of the year, and that level of activity has continued into 2013. We finished the highest portfolio growth year in our Company’s history by entering Brazil with an 800-tower acquisition. We increased the size of our tower portfolio by over 60% in 2012, adding quality towers and entering a new market that we believe will fuel growth for years to come. We accomplished all this portfolio growth while staying within our target leverage levels. Our strong fourth quarter results allow us to increase the mid-points on certain key metrics within our full-year 2013 Outlook. We expect to produce material growth in all key metrics again in 2013, including Adjusted EBITDA and AFFO per share.”

Outlook

The Company is providing its first 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 assumes the acquisition of only those tower assets under contract at the time of this press release. 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. The 2013 Outlook also contemplates refinancing all of the obligations under the Company’s 1.875% Notes upon maturity in cash. The Company currently estimates that its obligations at maturity of the 1.875% Notes will be approximately $615 million (based on an assumed $70.00 per share common stock price) net of prior conversions and the benefits of hedges entered into in conjunction with the 1.875% Notes, and the 2013 Outlook assumes that these amounts will be refinanced with $600 million of new debt financing at an estimated annual interest rate of 3.5% and the remainder from cash on hand. Finally, the Company’s Outlook also assumes an average foreign currency exchange rate of 2.0 Brazilian Reais to 1.0 U.S. Dollar for the first quarter and full year 2013.

Conference Call Information

SBA Communications Corporation will host a conference call on Friday, February 22, 2013 at 10:00 AM (EST) to discuss the quarterly results. The call may be accessed as follows:

Information Concerning Forward-Looking Statements

This press release includes forward-looking statements, including statements regarding the Company’s expectations or beliefs regarding (i) the Company’s financial and operational guidance for the first quarter of 2013 and full year 2013, (ii) the Company’s expectation that it will produce material growth in all key metrics in 2013, (iii) the Company’s belief that pending acquisitions will close by the end of the second quarter of 2013, (iv) spending additional capital in 2013 on acquiring revenue producing assets not yet identified or under contract, (v) the Company’s estimate of the amount of obligations that will be due upon the maturity of the 1.875% Notes, (vi) the Company’s ability to refinance its 1.875% Notes and the terms of such refinancing, (vii) the Company’s expectation regarding new tower builds in 2013, (viii) the Company’s assumptions regarding Brazil’s foreign exchange rates, and (ix) the Company’s expectations regarding the effect of entering into the Brazilian market on the Company’s growth. These forward-looking statements may be affected by the risks and uncertainties in the Company’s business. This information is qualified in its entirety by cautionary statements and risk factor disclosures contained in the Company’s Securities and Exchange Commission filings, including the Company’s annual report on Form 10-K filed with the Commission on February 27, 2012.

The Company wishes to caution readers that certain important factors may have affected and could in the future affect the Company’s actual results and could cause the Company’s actual results for subsequent periods to differ materially from those expressed in any forward-looking statement made by or on behalf of the Company. With respect to the Company’s expectations regarding all of these statements, including its financial and operational guidance, such risk factors include, but are not limited to: (1) the ability and willingness of wireless service providers to maintain or increase their capital expenditures; (2) the Company’s ability to effectively integrate acquired towers into its business and to achieve the financial results projected in its valuation models for the acquired towers; (3) the Company’s ability to refinance its 1.875% Notes on expected terms; (4) the Company’s ability to successfully manage the risks associated with international operations, including risks associated with land ownership; (5) the Company’s ability to secure and retain as many site leasing tenants as planned at anticipated lease rates; (6) the impact of continued consolidation among wireless service providers on the Company’s leasing revenue; (7) the Company’s ability to secure and deliver anticipated services business at contemplated margins; (8) the Company’s ability to maintain expenses and cash capital expenditures at appropriate levels for its business; (9) the Company’s ability to acquire land underneath towers on terms that are accretive; (10) the Company’s ability to protect its rights to the land under its towers; (11) the Company’s ability to realize economies of scale from its tower portfolio; (12) the Company’s ability to comply with covenants and the terms of its credit instruments; (13) the economic climate for the wireless communications industry in general and the wireless communications infrastructure providers in particular, and (14) the continued dependence on towers and outsourced site development services by the wireless carriers. With respect to the Company’s plan for new builds, these factors also include zoning approvals, weather, availability of labor and supplies and other

factors beyond the Company’s control that could affect the Company’s ability to build 380-400 towers in 2013. With respect to its expectations regarding the ability to close pending tower acquisitions, these factors also include satisfactorily completing due diligence, the ability and willingness of each party to fulfill their respective closing conditions and the availability of cash on hand, borrowing capacity under the Revolving Credit Facility or shares of the Company’s Class A common stock to pay the anticipated consideration.

With respect to the Company’s expectations regarding the amount of obligations that will be due on the 1.875% Notes at maturity, the Company has used an assumed stock price for purposes of providing investors a basis for analyzing such risk, however, the Company is not estimating, nor providing guidance, that its stock price either on the maturity date of the 1.875% Notes or for the measurement period specified in the indenture will be $70.00. If the stock price of SBA’s common stock for the measurement period specified in the indenture is less than such price, then SBA’s obligations under the indenture would be less than the estimated amount. Conversely if the stock price of SBA’s common stock for the measurement period specified in the indenture exceeds such price, then SBA’s total obligations would exceed the estimated amount.

This press release contains non-GAAP financial measures. Reconciliation of each of these non-GAAP financial measures is presented below under “Non-GAAP Financial Measures.”

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.

The tables below set forth the reconciliations of FFO and AFFO to their most comparable GAAP measurement. AFFO for each of the periods set forth in the Outlook section above will be calculated in the same manner:

Net Debt, Leverage Ratio, and Secured Leverage Ratio

The Debt and Leverage calculations are as follows:
