SBA Communications Corporation Reports Third Quarter 2021 Results;

Updates Full Year 2021 Outlook; and Declares Quarterly Cash Dividend

Boca Raton, Florida, November 1, 2021 (BUSINESS NEWSWIRE) - SBA Communications Corporation (Nasdaq: SBAC) ("SBA" or the "Company") today reported results for the quarter ended September 30, 2021.

Highlights of the third quarter include:

In addition, the Company announced today that its Board of Directors has declared a quarterly cash dividend of $0.58 per share of the Company's Class A Common Stock. The distribution is payable December 16, 2021 to the shareholders of record at the close of business on November 18, 2021.

"The increased level of US wireless carrier activity we experienced last quarter continued in the third quarter," stated Jeffrey Stoops, President and CEO. "US wireless carrier activity continued at materially higher levels compared to the beginning of the year. Domestically, we produced record services revenue, surpassing our second quarter record, and our leasing and services backlogs reached new multi-year highs at quarter-end. While we expect some revenue recognition from third quarter leasing activity by year-end, contributing to our increased full-year 2021 Outlook, we anticipate the substantial majority will begin to be recognized in 2022. Based on our backlogs and conversations with our customers, we expect elevated domestic leasing activities to continue through 2022 and perhaps beyond. Internationally, our leasing results in the third quarter were once again solid and ahead of plan, as our international markets slowly but steadily return to pre-pandemic levels of activity. In addition to growth from increased customer activity and portfolio growth, sound cost controls, substantial stock repurchases and interest rate savings through refinancing a material portion of our debt have allowed us to increase our full-year outlook for AFFO per share and other key financial metrics. Our balance sheet remains strong, further strengthened by material refinancing success, and our net debt/ Adjusted EBITDA leverage remains within our target range. The combination of strong operating results, strong expected demand for the remainder of the year and excellent capital allocation and balance sheet management gives us great confidence for the remainder of 2021 and into 2022. In addition, pending and anticipated major spectrum auctions in the US and a few of our larger international markets provide additional optimism for heightened carrier activity for the foreseeable future."

Furthermore, the Company's forward-looking statements and its 2021 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.

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, Tower Cash Flow, and Tower Cash Flow Margin; (ii) Adjusted EBITDA, Annualized Adjusted EBITDA, and Adjusted EBITDA Margin; (iii) Funds from Operations ("FFO"), Adjusted Funds from Operations ("AFFO"), and AFFO per share; (iv) Net Debt, Net Secured Debt, Leverage Ratio, and Secured Leverage Ratio (collectively, our "Non-GAAP Debt Measures"); and (v) 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.

11

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 and asset impairment and decommission costs). 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 (1) our asset base (primarily depreciation, amortization and accretion and asset impairment and decommission costs) and (2) certain non-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods and the non-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) 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 2016 Senior Notes, 2020 Senior Notes, and 2021 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.

12

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.

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

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:
