FOR IMMEDIATE RELEASE

SBA Communications Corporation Reports 1^st Quarter 2017 Results;

Updates Full Year 2017 Outlook

Boca Raton, Florida, May 1, 2017 (GLOBE NEWSWIRE) — SBA Communications Corporation (Nasdaq: SBAC) (“SBA” or the “Company”) today reported results for the quarter ended March 31, 2017.

Highlights of the first quarter include:

“The first quarter was a good start to 2017 for SBA,” commented Jeffrey A. Stoops, President and CEO. “Our results were ahead of our expectations and allow us to increase our full year Outlook. Domestic carrier activity in the first quarter improved slightly over 2016 levels, and international carrier activity was solid and stable. With the FirstNet award and the 600 MHz auction now realized, and 5G deployments on the horizon, we expect domestic customer demand to remain solid for years to come. Against this solid demand backdrop, we intend to continue to allocate capital for portfolio growth and stock repurchases such as to maintain our target leverage in the 7.0x to 7.5x net debt/adjusted EBITDA range and in some cases exceed that range temporarily for the right opportunity. With our solid first quarter results, combined with our expectations around future customer demand and capital allocation opportunities, we are solidly on track to achieve our long term goal of $10 or more of AFFO per share in 2020.”

Selected Capital Expenditure Detail

Communication Site Portfolio Summary

Segment Operating Profit and Segment Operating Profit Margin

Domestic site leasing and International site leasing are the two segments within our site leasing business. Segment operating profit is a key business metric and one of our two measures of segment profitability. The calculation of Segment operating profit for each of our segments is set forth below.

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 useful indicators of the performance of our site leasing operations;

(2) Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance. Adjusted EBITDA is the primary measure used by management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations. Management believes that Adjusted EBITDA helps investors or other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors, by excluding the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results. Management also believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of REITs. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used in our debt covenant calculations. Adjusted EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance;

(3) FFO, AFFO and AFFO per share, which are metrics used by our public company peers in the communication site industry, provide investors useful indicators of the financial performance of our business and permit investors an additional tool to evaluate the performance of our business against those of our two principal competitors. On October 3, 2016, SBA’s Board authorized SBA to take the steps necessary to be subject to tax as a REIT commencing with the taxable year ending December 31, 2016. We believe that we are operating in a manner that complies with the REIT rules as of January 1, 2016. As a result, we have updated our definition of FFO. Under the revised definition, FFO no longer includes an adjustment to reflect our estimate of our cash taxes had we been a REIT. However, AFFO continues to exclude the non-cash portion of our reported tax provision. We refer to the prior definition as FFO, as previously defined. FFO, AFFO, and AFFO per share are also used to address questions we receive from analysts and investors who routinely assess our operating performance on the basis of these performance measures, which are considered industry standards. We believe that FFO helps investors or other interested parties meaningfully evaluate financial performance by excluding the impact of our asset base (primarily depreciation, amortization and accretion). We believe that AFFO and AFFO per share help investors or other interested parties meaningfully evaluate our financial performance as they include (1) the impact of our capital structure (primarily interest expense on our outstanding debt) and (2) sustaining capital expenditures and exclude the impact of our (1) asset base (primarily depreciation, amortization and accretion) and (2) certain non-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods. GAAP requires rental revenues and expenses related to leases that contain specified rental increases over the life of the lease to be recognized evenly over the life of the lease. In accordance with GAAP, if payment terms call for fixed escalations, or rent free periods, the revenue or expense is recognized on a straight-lined basis over the fixed, non-cancelable term of the contract. We only use AFFO as a performance measure. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows from operations or as residual cash flow available for discretionary investment. We believe our definition of FFO is consistent with how that term is defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and that our definition and use of AFFO and AFFO per share is consistent with those reported by the other communication site companies;

(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 and, to the extent that such measures are calculated on Net Debt are net of our cash and cash equivalents, short-term restricted cash, and short-term investments; and

(5) Our Constant Currency Measures provide management and investors the ability to evaluate the performance of the business without the impact of foreign currency exchange rate fluctuations.

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 2014 Senior Notes and 2016 Senior 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.

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, total cash site leasing revenue, and International cash 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, (4) Net income, (5) diluted earnings per share, (6) Adjusted EBITDA, and (7) AFFO and AFFO per share.

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

We use FFO as defined by NAREIT. Given that we have announced our intention to elect REIT status as of January 1, 2016 and our belief that we are operating in a manner that complies with the REIT rules, FFO no longer includes an adjustment to reflect our estimate of our cash taxes had we been a REIT. However, AFFO continues to exclude the non-cash portion of our reported tax provision.

The tables below set forth the reconciliations of FFO and AFFO to their most comparable GAAP measurement.

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:
