Boca Raton, Florida, April 23, 2015 (GLOBE NEWSWIRE) — SBA Communications Corporation (Nasdaq: SBAC) (“SBA” or the “Company”) today reported results for the quarter ended March 31, 2015. Highlights of the results include:

First quarter over year earlier period:

“We got off to a solid start to 2015 in the first quarter”, commented Jeffrey A. Stoops, President and Chief Executive Officer. “Operating results were ahead of expectations, driven by solid revenue growth and strong expense control. Customers were active with network improvements, which benefited both our leasing and services segments. Customer activity and our backlogs remain strong. Margin results were particularly strong, evidencing the quality of our assets and the strength of our execution. The integration of our international assets is ahead of plan, contributing to the strong margin results. Our balance sheet and access to capital are in great shape. We intend to keep our balance sheet invested at current leverage levels, and will continue to look for additional investment opportunities that meet our return criteria. Based on our start to the year, we remain optimistic that we will achieve our portfolio growth targets and in the process drive additional growth in AFFO per share.”

Investing Activities

During the first quarter of 2015, SBA purchased 59 communication sites for $42.6 million in cash. SBA also built 107 towers during the first quarter of 2015. As of March 31, 2015, SBA owned or operated 24,393 communication sites, 15,151 of which are located in the United States and its territories, and 9,242 of which are located internationally. In addition, the Company spent $14.0 million to purchase land and easements and to extend lease terms. Total cash capital expenditures for the first quarter of 2015 were $121.4 million, consisting of $7.4 million of non-discretionary cash capital expenditures (tower maintenance and general corporate) and $114.0 million of discretionary cash capital expenditures (new tower builds, tower augmentations, acquisitions, purchasing land and easements, and capital expenditures associated with the purchase and refurbishment of a new headquarters building).

Subsequent to the first quarter of 2015, the Company acquired 20 communication sites for an aggregate consideration of $17.6 million in cash. In addition, the Company has agreed to purchase in the U.S. and internationally 408 communication sites for an aggregate amount of $280.3 million. The Company anticipates that most of these acquisitions will be consummated by the end of the third quarter of 2015.

Financing Activities and Liquidity

SBA ended the first quarter with $8.0 billion of total debt, $108.6 million of cash and cash equivalents, short-term restricted cash, and short-term investments, and $7.9 billion of Net Debt (as defined below). SBA’s Net Debt and Net Secured Debt to Annualized Adjusted EBITDA Leverage Ratios were 7.3x and 5.4x, respectively.

During the first quarter, the Company settled the remaining outstanding warrants originally sold in connection with its 4.0% Convertible Notes. The warrants represented approximately 2.1 million underlying shares of Class A common stock, and the Company satisfied its obligations by paying $150.9 million in cash, of which $15.6 million was paid in the second quarter of 2015.

On February 5, 2015, SBA amended its senior secured Revolving Credit Facility to (1) increase the size of the facility by $230.0 million to $1.0 billion, (2) extend the maturity date to February 5, 2020, and (3) reduce the interest rate between 37.5 and 50.0 basis points depending on Borrower leverage as defined in the Credit Agreement.

As of the date of this press release, there was $235.0 million outstanding under the $1.0 billion Revolving Credit Facility, and the amount available based on specified covenants under the facility is $765.0 million.

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 2015 Outlook and updating its Full Year 2015 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 second quarter 2015 Outlook assumes approximately $12.9 million of non-cash straight-line leasing revenue while the full year 2015 Outlook assumes approximately $50.9 million of non-cash straight-line leasing revenue. The full year 2015 Outlook for site leasing revenue, Tower Cash Flow, Adjusted EBITDA and AFFO includes an assumed negative impact of $16.0 million associated with 2015 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 second quarter 2015 Outlook and full year 2015 Outlook assume the acquisitions of only those communication sites under contract at the time of this press release. The Company intends to spend additional capital in 2015 on acquiring revenue producing assets not yet identified or under contract, the impact of which is not reflected in the 2015 guidance. The Company’s full year 2015 Outlook includes new tower builds in the U.S. and internationally of 575 to 595 towers. The Outlook does not contemplate any new financings or any repurchases of the Company’s stock during 2015. Finally, the Company’s Outlook assumes an average foreign currency exchange rate of 3.05 Brazilian Reais to 1.0 U.S. Dollar and 1.25 Canadian dollars to 1.0 U.S. Dollar for the second quarter of 2015 and the remainder of full year 2015. When compared to the Company’s Full Year 2015 Outlook provided February 27, 2015, the variances in the actual first quarter foreign currency exchange rates versus the Company’s assumptions, and the changes in the Company’s foreign currency rate assumptions for the remainder of the year negatively impact the full year 2015 Outlook by approximately $10.5 million for Site Leasing Revenue, $6.0 million for Tower Cash Flow, and $5.5 million for Adjusted EBITDA and AFFO.

Segment Operating Profit and Segment Operating Profit Margin

The reconciliation of Site Leasing Segment Operating Profit and Site Development Segment Operating Profit and the calculation of Segment Operating Profit Margin are as follows:

Non-GAAP Financial Measures

The press release contains non-GAAP financial measures including (i) Cash Site Leasing Revenue; (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”); (v) Funds from Operations (“FFO”), Adjusted Funds from Operations (“AFFO”), and AFFO per share, and (vi) certain financial metrics after eliminating the impact of changes in foreign currency exchange rates (collectively, our “Constant Currency Measures”).

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) Cash Site Leasing Revenue and Tower Cash Flow are indicators of the performance of our site leasing operations;

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

(3) 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; and

(4) Our Constant Currency measures provide management and investors the ability to evaluate the performance of the business without the impact of foreign exchange fluctuations.

11

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 and indentures relating to our 5.625% Notes, 5.75% Notes, and 4.875% 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.

Cash Site Leasing Revenue, Tower Cash Flow, and Tower Cash Flow Margin

The tables below set forth the reconciliation of Cash Site Leasing Revenue and Tower Cash Flow to their most comparable GAAP measurement and Tower Cash Flow Margin, which is calculated by dividing Tower Cash Flow by Cash Site Leasing Revenue. Tower Cash Flow for each of the periods set forth in the Outlook section above will be calculated in the same manner.

12

Adjusted EBITDA, Annualized Adjusted EBITDA, and Adjusted EBITDA Margin

The table below sets forth the reconciliation of Adjusted EBITDA to its most comparable GAAP measurement. Adjusted EBITDA for each of the periods set forth in the Outlook section above will be calculated in the same manner:

The calculation of Adjusted EBITDA Margin is as follows:

13

Funds from Operations (“FFO”) and Adjusted Funds from Operations (“AFFO”)

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:

14

Net Debt, Net Secured Debt, Leverage Ratio, and Secured Leverage Ratio

Net Debt is calculated using the notional principal amount of outstanding debt. Under GAAP policies, the notional principal amount of the Company’s outstanding debt is not necessarily reflected on the face of the Company’s financial statements.

The Net Debt and Leverage calculations are as follows:

Financial Metrics After Eliminating The Impact Of Changes In Foreign Currency Exchange Rates

We eliminate the impact of changes in foreign currency exchange rates for each of the following financial metrics by dividing the current period’s financial results by the average monthly exchange rates of the prior year period. The table below provides the reconciliation of the reported growth rate year-over-year, of each of the following measures to the growth rate, after eliminating the impact of changes in foreign currency exchange rates to such measure: (1) total site leasing revenue and international site leasing revenue, (2) total site leasing segment operating profit and international site leasing segment operating profit, (3) total Tower Cash Flow and international Tower Cash Flow, and (4) Adjusted EBITDA.
