SBA Communications (SBAC) 8-K Updates Full Year 2019 Outlook

Exhibit 99.1

FOR IMMEDIATE RELEASE

SBA Communications Corporation Reports First Quarter 2019 Results;

Updates Full Year 2019 Outlook

Boca Raton, Florida, April 29, 2019 (BUSINESS NEWSWIRE) — SBA Communications Corporation (Nasdaq: SBAC) (“SBA” or the “Company”) today reported results for the quarter ended March 31, 2019.

Highlights of the first quarter include:

• Strong leasing and services results

• Net income of $26.0 million or $0.23 per share

• AFFO per share growth of 14.6% over the year earlier period on a constant currency basis

• Increased 2019 Outlook for Revenue, Adjusted EBITDA and AFFO

“We had a great start to 2019,” commented Jeffrey A. Stoops, President and CEO. “Our customers rolled into the new year with the continued strong levels of activity we saw in the second half of 2018, and that level of activity continues. In the U.S., both our leasing and our services results in the first quarter were ahead of expectations, contributing to the increase in our full year Outlook. Internationally, leasing activity remains strong as well, with changes in the International Outlook driven entirely by foreign currency movements. Against this favorable demand environment, we executed very well and produced material growth in AFFO per share. We believe 2019 is shaping up to be another strong year for SBA.”

The Company has agreed to purchase and anticipates closing on 256 additional communication sites for an aggregate amount of $123.9 million. The Company anticipates that the majority of these acquisitions will be consummated by the end of the third quarter of 2019.

Financing Activities and Liquidity

SBA ended the first quarter of 2019 with $9.8 billion of total debt, $7.2 billion of total secured debt, $142.0 million of cash and cash equivalents, short-term restricted cash, and short-term investments, and $9.7 billion of Net Debt.

The Company did not repurchase any shares of its Class A common stock during the first quarter. As of the date of this press release, the Company has $204.5 million of authorization remaining under the stock repurchase plan authorized on February 16, 2018.

Outlook

The Company is updating its full year 2019 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 2019 Outlook assumes the acquisitions of only those communication sites under contract and anticipated to close at the time of this press release. The Company may spend additional capital in 2019 on acquiring revenue producing assets not yet identified or under contract, the impact of which is not reflected in the 2019 guidance. The Outlook also does not contemplate any repurchases of the Company’s stock during 2019. The Outlook contemplates one new financing during the third quarter of 2019 to refinance the Company’s2014-1C Tower Securities. The assumed interest rate of this new financing is 4.25%. There are no additional new financings contemplated in our 2019 Outlook.

The Company’s Outlook assumes an average foreign currency exchange rate of 3.90 Brazilian Reais to 1.0 U.S. Dollar and 1.33 Canadian Dollars to 1.0 U.S. Dollar throughout the last three quarters of 2019. When compared to the Company’s initial full year 2019 Outlook provided February 21, 2019, 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 impacted the full year 2019 Outlook by approximately $4.5 million for Site Lease Revenue, $3.0 million for Tower Cash Flow, and $2.7 million for Adjusted EBITDA and AFFO.

The Company wishes to caution readers that these forward-looking statements may be affected by the risks and uncertainties in the Company’s business as well as other 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 identify and acquire sites at prices and upon terms that will provide accretive portfolio growth; (3) the Company’s ability to accurately identify and manage any risks associated with its acquired sites, to effectively integrate such sites into its business and to achieve the anticipated financial results; (4) the Company’s ability to secure and retain as many site leasing tenants as planned at anticipated lease rates; (5) the impact of continued consolidation among wireless service providers, including the impact of the potentialT-Mobile and Sprint merger, on the Company’s leasing revenue; (6) the Company’s ability to successfully manage the risks associated with international operations, including risks associated with foreign currency exchange rates; (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 while seeking to attain its investment goals; (9) the Company’s ability to acquire land underneath towers on terms that are accretive; (10) the economic climate for the wireless communications industry in general and the wireless communications infrastructure providers in particular in the United States, Brazil, and internationally; (11) the Company’s ability to obtain future financing at commercially reasonable rates or at all; (12) the ability of the Company to achieve its long-term stock repurchases strategy, which will depend, among other things, on the trading price of the Company’s common stock, which may be positively or negatively impacted by the repurchase program, market and business conditions; (13) the Company’s ability to achieve the new builds targets included in its anticipated annual portfolio growth goals, which will depend, among other things, on obtaining zoning and regulatory approvals, weather, availability of labor and supplies and other factors beyond the Company’s control that could affect the Company’s ability to build additional towers in 2019; and (14) the Company’s ability to meet its total portfolio growth, which will depend, in addition to the new build risks, on the availability of sufficient towers for sale to meet our targets, competition from third parties for such acquisitions and our ability to negotiate the terms of, and acquire, these potential tower portfolios on terms that meet our internal return criteria. With respect to its expectations regarding the ability to close pending acquisitions, these factors also include satisfactorily completing due diligence, the amount and quality of due diligence that the Company is able to complete prior to closing of any acquisition and its ability to accurately anticipate the future performance of the acquired towers, the ability to receive required regulatory approval, the ability and willingness of each party to fulfill their respective closing conditions and their contractual obligations and the availability of cash on hand or borrowing capacity under the Revolving Credit Facility to fund the consideration. With respect to the repurchases under the Company’s stock repurchase program, the amount of shares repurchased, if any, and the timing of such repurchases will depend on, among other things, the trading price of the Company’s common stock, which may be positively or negatively impacted by the repurchase program, market and business conditions, the availability of stock, the Company’s financial performance or determinations following the date of this announcement in order to use the Company’s funds for other purposes. Furthermore, the Company’s forward-looking statements and its 2019 outlook assumes that the Company continues to qualify for treatment as a REIT for U.S. federal income tax purposes and that the Company’s business is currently operated in a manner that complies with the REIT rules and that it will be able to continue to comply with and conduct its business in accordance with such rules.

Non-GAAP Financial Measures

The press release containsnon-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 thesenon-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. 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) certainnon-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods and thenon-cash portion of our reported tax provision. 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)    OurNon-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

11

(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 ourNon-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, 2016 Senior Notes, and 2017 Senior Notes. Thesenon-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 financial metrics listed in the table below by dividing the current period’s financial results by the average monthly exchange rates of the prior year period, and by eliminating the impact of the remeasurement of our intercompany loans. The table below provides the reconciliation of the reported growth rate year-over-year of each of such measures to the growth rate after eliminating the impact of changes in foreign currency exchange rates to such measure.
