CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.BASIS OF PRESENTATION

The accompanying consolidated financial statements should be read in conjunction with the Annual Report on Form 10-K for the fiscal year ended December 31, 2013 for SBA Communications Corporation and its subsidiaries (the “Company”). These financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, omit or condense certain footnotes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States. In the opinion of the Company’s management, all adjustments (consisting of normal recurring accruals) considered necessary for fair financial statement presentation have been made. The results of operations for an interim period may not give a true indication of the results for the year. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in consolidated financial statements and accompanying notes. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial statements and accompanying notes, the actual amount of such estimates, when known, will vary from these estimates.

Foreign Currency Translation 

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive income (loss) in shareholders’ equity.

2.FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis— The Company’s earnouts related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs. Level 3 valuations rely on unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The Company determines the fair value of acquisition-related contingent consideration and any subsequent changes in fair value using a discounted probability-weighted approach using Level 3 inputs. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on historical internal observations related to the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its obligation if the performance targets contained in various acquisition agreements were met was $19.8 million and $30.1 million as of June 30, 2014 and December 31, 2013, respectively, which the Company recorded in accrued expenses on its Consolidated Balance Sheets. The maximum potential obligation related to the performance targets was $31.6 million as of June 30, 2014.

The following summarizes the activity of the accrued earnouts:

	2014		2013
	(in thousands)
Beginning balance, December 31,	$	30,063	$	9,840
Additions		5,375		534
Payments		(14,439)		(1,311)
Expirations		(274)		(1,786)
Change in Estimate		(1,373)		(280)
Foreign currency translation adjustments		427		18
Ending balance, June 30,	$	19,779	$	7,015

Items Measured at Fair Value on a Nonrecurring Basis— The Company’s long-lived assets, intangibles, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. The Company considers many factors and makes certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. The fair value of the long-lived assets, intangibles, and asset retirement obligations is calculated using a discounted cash flow model. During the threeand sixmonths ended June 30, 2014, the Company recognized an impairment charge of $4.0 million and $7.6 million, respectively. The impairment charge

7

includes the write off of $3.3 million and $5.6 million in carrying value of decommissioned towers and other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the threeand sixmonths ended June 30, 2014,  respectively.  During the three and six months ended June 30, 2013, the Company recognized an impairment charge of $6.5 million and $10.2 million, respectively. The impairment charge includes the write off of $6.1 million and $7.4 million in carrying value of decommissioned towers and other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and six months ended June 30, 2013, respectively. These write offs result from the Company’s analysis that the future cash flows from certain towers would not recover the carrying value of the investment in those towers. Impairment charges and the related impaired assets relate to the Company’s site leasing operating segment.

Fair Value of Financial Instruments— The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments. Short-term investments consisted of $5.6 million and $5.2 million in certificate of deposits, as of June 30, 2014 and December 31, 2013, respectively. The Company’s estimate of the fair value of its held-to-maturity investments in treasury and corporate bonds, including current portion, are based primarily upon Level 1 reported market values. As of June 30, 2014, the carrying value and fair value of the held-to-maturity investments, including current portion, were $1.2 million and $1.3 million, respectively. As of December 31, 2013, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.1 million and $1.3 million, respectively.

The Company determines fair value of its debt instruments utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to approximate the carrying value because the interest payments are based on Eurodollar rates that reset every month. The Company does not believe its credit risk has changed materially from the date the applicable Eurodollar Rate plus 187.5 basis points was set for the Revolving Credit Facility. The following table reflects fair values, principal balances, and carrying values of the Company’s debt instruments (see Note 11).

Pursuant to the terms of the Tower Securities (see Note 11), the Company is required to establish a securitization escrow account, held by an indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to towers, (3) trustee and servicing expenses, and (4) management fees and to reserve a portion of advance rents from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 11) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as restricted cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily relates to the Company’s tower removal obligations. As of June 30, 2014, the Company had $40.7 million in surety bonds and payment and performance bonds for which it was only required to post $3.1 million in collateral. As of December 31, 2013, the Company had $42.0 million in surety, payment and performance bonds for which it was only required to post $6.1 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. As of June 30, 2014, the Revolving Credit Facility consisted of a revolving loan under which up to$770.0million aggregate principal amount may be borrowed, repaid and redrawn, subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest at the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated TotalDebt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. If not earlier terminated by SBA Senior Finance II LLC (“SBA Senior Finance II”), a subsidiary of the Company, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, May 9, 2017. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A per annum commitment fee of 0.375% to 0.5% of the unused commitments under the Revolving Credit Facility is charged based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Senior Credit Agreement). SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be reflective of the total amounts outstanding during such period.

On February 7, 2014, SBA Senior Finance II entered into a Second Amended and Restated Credit Agreement (as amended and restated, the “Senior Credit Agreement”) with several banks and other financial institutions or entities from time to time parties to the Senior Credit Agreement to, among other things, obtain a $1.5 billion senior secured term loan(the “2014 Term Loan”) and to amend certain terms of the existing senior credit agreement. In addition to providing for the 2014 Term Loan, the Senior Credit Agreement was amended to, among other things, amend the terms of certain events of default, modify certain negative covenants and remove the parent financial maintenance leverage covenant to reflect the increased size of SBA Senior Finance II and its restricted subsidiaries.  All other material terms of the Senior Credit Agreement, as it existed prior to February 7, 2014, remained unchanged.

4.0% Convertible Senior Notes due 2014

On April 24, 2009,  the Company issued $500.0 million of its4.0% Convertible Senior Notes (“4.0% Notes”) in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The  Company incurred fees of $11.7 million with the issuance of the 4.0% Notes of which $7.7 million was recorded as deferred financing fees and $4.0 million was recorded as a reduction to shareholders’ equity.

The 4.0% Notes are convertible, at the holder’s option, into shares of the Company’s Class A common stock, at an initial conversion rate of 32.9164 shares of its Class A common stock per $1,000 principal amount of 4.0% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $30.38 per share or a 22.5% conversion premium based on the last reported sale price of $24.80 per share of the Company’s Class A common stock on the Nasdaq Global Select Market on April 20, 2009, the purchase agreement date.

Concurrently with the pricing of the 4.0% Notes, the Company entered into convertible note hedge and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 4.0% Notes is $30.38 per share of the Company’s Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share.

The Company is amortizing the debt discount on the 4.0% Notes utilizing the effective interest method over the life of the 4.0% Notes which increases the effective interest rate of the 4.0% Notes from its coupon rate of 4.0% to 12.8%. As of June 30, 2014, the carrying amount of the equity component related to the 4.0% Notes was $166.9 million.

The 4.0% Notes are reflected in current maturities of long-term debt in the Consolidated Balance Sheets at their carrying value. The following table summarizes the balances for the 4.0% Notes:

	As of
	June 30, 2014		December 31, 2013
	(in thousands)
Principal balance	$	378,370	$	499,944
Debt discount		(8,170)		(31,550)
Carrying value	$	370,200	$	468,394

At the time of the issuance of the 4.0% Notes, the Company elected to settle its conversion obligations in stock. Effective March 17, 2014, the Company elected to settle the principal amount of any conversions in cash and any additional conversion consideration at the conversion rate then applicable in shares of its Class A common stock. Concurrently with the settlement of any 4.0% Notes converted, the Company will settle the associated convertible note hedges and receive an equal number of shares to those issued to the noteholders.

During the  three and six months ended June 30, 2014, the 4.0% Notes were convertible based on the fact that the closing price per share of the Company’s Class A common stock exceeded $39.49 for at least 20 trading days during the 30 consecutive trading day period ending on March 31, 2014 and December 31, 2013, respectively, and remain convertible as of the date of this filing.  During the three and six months ended June 30, 2014,  holders of the 4.0% Notes converted $121.5 million and $121.6 million, respectively, in principal amount of 4.0% Notes. The Company settled its conversion obligation through the payment of the principal amount in cash and the issuance of 2.7 million shares of its Class A common stock during the three and six months ended June 30, 2014.  Concurrently with these conversions, the related convertible note hedges were settled, and the Company received 2.7 million shares of its Class A common stock, of which 0.1 million shares were received subsequent to June 30, 2014.  As a result, the Company’s outstanding share count has not been impacted by the conversion of these notes. In addition, the Company received conversion notices totaling $11.3 million in principal amount of the 4.0% Notes which will settle during the third quarter of 2014 for cash and shares of its Class A common stock.

During the three months ended June 30, 2014, the Company paid $276.2 million to early settle approximately 30% of the outstanding warrants sold in connection with the issuance of the 4.0% Notes, representing approximately 4.9 million underlying shares of Class A common stock, scheduled to mature in the first quarter of 2015. Subsequent to June 30, 2014, the Company paid $66.5 million to early settle approximately 7.5% of the original total outstanding warrants, representing approximately 1.2 million

16

underlying shares, scheduled to mature in the first quarter of 2015. The Company’s obligations under the remaining 10.3 million warrants are scheduled to settle over a 60 trading day period commencing on January 2, 2015 unless otherwise settled early.

Interest on the 4.875% Notes is payable semi-annually on January 15 and July 15 of each year beginning January 15, 2015. Net proceeds from the 4.875% Notes were used to pay the conversion obligations with respect to $121.5 million aggregate principal amount of the 4.0% Notes. The remaining net proceeds will be used to redeem all of the 8.25% Notes due 2019 including the associated call premium and for general corporate purposes.

BNDES Loans

During the six months ended June 30, 2014, the Company had borrowings of $0.4 million and repayments of $6.3 million under the BNDES Loans.  The BNDES Loans were repaid in full in April 2014.

12.SHAREHOLDERS’ EQUITY

Common Stock equivalents

The Company has potential common stock equivalents related to its outstanding stock options (see Note 13), restricted stock units, and the 4.0% Notes and related warrants (see Note 11). These potential common stock equivalents were not included in diluted

17

loss per share because the effect would have been anti-dilutive for each of the three and six months ended June 30, 2014 and 2013, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for each period presented.

Stock Repurchases

The Company’s Board of Directors authorized a stock repurchase program on April 27, 2011. This program authorizes the Company to purchase, from time to time, up to $300.0 million of the Company’s outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by the Company’s Board of Directors at any time in the Company’s sole discretion.

During the six months ended June 30, 2014, the Company did not repurchase any shares in conjunction with the stock repurchase program. As of June 30, 2014, the Company had a remaining authorization to repurchase an additional $150.0 million of its common stock under its current $300.0 million stock repurchase program. 

13.STOCK-BASED COMPENSATION

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a combination of historical data and historical volatility to establish the expected volatility. Historical data is used to estimate the expected option life and the expected forfeiture rate. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. The following assumptions were used to estimate the fair value of options granted using the Black-Scholes option-pricing model:

	For the six months ended
	June 30,
	2014	2013
Risk free interest rate	1.15% - 1.325%	0.51% - 1.03%
Dividend yield	0.0%	0.0%
Expected volatility	22.0%	25.0% - 29.0%
Expected lives	4.4 years	3.9 - 4.8 years

14.INCOME TAXES

During the three months ended June 30, 2014, the Company had federal and state taxable income which was offset by net operating losses for the six months ended June 30, 2014.  The Company had U.S. taxable losses during the threemonths ended June 30, 2014 and 2013 and for the six months ended June 30, 2013, and, as a result, federal and state net operating loss carry-forwards have been generated. The U.S. federal and state net operating loss carry-forwards of the Company have a full valuation allowance as management believes it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to realize the losses. A foreign tax provision is recognized because certain international subsidiaries of the Company have profitable operations or a net deferred tax liability position.

15.SEGMENT DATA

The Company operates principally in two business segments: site leasing and site development. The Company’s reportable segments are strategic business units that offer different services. They are managed separately based on the fundamental differences in their operations. The site leasing segment includes results of the managed and sublease businesses. The site development segment includes the results of both consulting and construction related activities.

Commencing in the second quarter of 2014, the Company expanded the presentation of its site leasing business into two reporting segments, domestic site leasing and international site leasing as a result of its international site leasing revenues exceeding 10% of total revenues.All prior periods have been restated to conform to the current year presentation.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We are a leading independent owner and operator of wireless communications tower structures, rooftops and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or “sites.” Our principal operations are in the United States and its territories. In addition, we own and operate towers in Canada, Central America, and South America. Our primary business line is our site leasing business, which contributed 96.2% of our total segment operating profit for the six months ended June 30, 2014. In our site leasing business, we (1) lease antenna space to wireless service providers on towers that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. The towers that we own have been constructed by us at the request of a wireless service provider, constructed based on our own initiative, or acquired. As of June 30, 2014, we owned 22,305 towers, a substantial portion of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. We also managed or leased approximately 5,500 actual or potential towers, approximately 500 of which were revenue producing as of June 30, 2014. Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.

Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts in the United States, Canada, Central America, and South America. Commencing in the second quarter of 2014, we have classified our site leasing business into two reporting segments, domestic site leasing and international site leasing as a result of our international site leasing revenues exceeding 10% of our total revenues.

Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless, T-Mobile, Oi, Digicel, American Movile, and Telefonica.

Cost of site leasing revenue primarily consists of:

•Rental payments on ground leases and other underlying property interests;

•Straight-line rent adjustment for the difference between rental payments made and the expense recorded as if the payments had been made evenly throughout the lease term (which may include renewal terms) of the underlying property interests;

•Property taxes;

•Site maintenance and monitoring costs (exclusive of employee related costs);

•Utilities;

•Property insurance; and

•Deferred lease origination cost amortization.

As of June 30, 2014, approximately 72% of our tower structures were located on parcels of land that we own, land subject to perpetual easements, or parcels of land in which we have a leasehold interest that extends beyond 20 years. For any given tower, costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned towers do not generally increase as a result of adding additional customers to the tower. The amount of direct costs associated with operating a tower varies from site to site depending on the taxing jurisdiction and the height and age of the tower. The ongoing maintenance requirements are typically minimal and include replacing lighting systems, painting a tower, or upgrading or repairing an access road or fencing.

Domestic Site Leasing

As of June 30, 2014, we had 15,038 sites in the United States.  For the three months ended June 30, 2014, we generated 83.8% of our site leasing revenue from these sites. In the United States, wireless service providers typically enter into different tenant leases with us, each of which relates to the lease or use of space at an individual tower. Our tenant leases in the United States are generally for an initial term of five to ten years with five 5-year renewal periods at the option of the tenant. These tenant leases typically contain

21

specific rent escalators, which average 3-4% per year, including the renewal option periods.  Our ground leases in the United States are generally for an initial term of five years or more with multiple renewal terms of 5-year periods, at our option, and provide for rent escalators which typically average 2-3% annually.

International Site Leasing

As of June 30, 2014, we had 7,267 sites in our international markets, located in Canada, Costa Rica, El Salvador, Guatemala, Nicaragua, Panama, and Brazil. For the three months ended June 30, 2014, we generated 16.2% of our site leasing revenue from these sites. Our operations in these countries are solely in the site leasing business, and we expect to expand operations through new builds and acquisitions.

Our tenant leases in Canada typically have similar terms and conditions as those in the United States with an initial term of five to ten years with five 5-year renewal periods at the option of the tenant.  These tenant leases typically contain specific rent escalators, which average 3-4% per year, including the renewal option periods.  Tenant leases in our Central America and Brazil markets typically have an initial term of 10 years with 5-year renewal periods.  In Central America, we have similar rent escalators to that of leases in the United States and Canada while our leases in Brazil typically escalate in accordance with a standard cost of living index.  In Brazil, site leases are typically governed by master lease agreements, which provide for the material terms and conditions that will govern the terms of the use of the site.  These site leases typically provide for a fixed rental amount and a pass-through charge for a portion of the underlying ground lease rent.  Our ground leases in Canada, Central America and Brazil generally have similar terms and conditions as those in the United States, except that the annual escalator in Brazil is a cost of living index.

In our Central American markets, significantly all of our tenant leases and most of our operating expenses, including our ground leases, are denominated in U.S. dollars. In our Central American markets, our local currency denominated operating expenses are principally limited to (1) permitting and other local fees, (2) utilities, (3) taxes, and (4) selling, general, and administrative expenses. In our Canadian and Brazilian operations, significantly all of our revenue and expenses are denominated in the respective local currency.

As indicated in the table below, our site leasing business generates substantially all of our total segment operating profit. For information regarding our operating segments, see Note 15 of our Condensed Notes to Consolidated Financial Statements included in this quarterly report.

(1)Site leasing segment operating profit and total segment operating profit are non-GAAP financial measures. We reconcile these measures and other Regulation G disclosures in this quarterly report in the section entitled Non-GAAP Financial Measures.

We believe that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional antenna space on our towers due to increasing minutes of network use and data transfer, network expansion and network coverage requirements. We believe our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs and minimal non-discretionary capital expenditures. Due to the relatively young age and mix of our tower portfolio, we expect future expenditures required to maintain these towers to be minimal. Consequently, we expect to grow our cash flows by (1) adding tenants to our towers at minimal incremental costs by using existing tower capacity or requiring wireless service providers to bear all or a portion of the cost of tower modifications and (2) executing monetary amendments as wireless service providers upgrade their equipment. Furthermore, because our towers are strategically positioned and our customers typically do not relocate, we have historically experienced low tenant lease terminations as a percentage of revenue.

Site Development Services

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Site development services revenues are earned primarily from providing a full range of end to end services to wireless service providers or companies providing development or project management services to wireless service providers. Our services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas; (4) support in buying or leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site development services at our towers and at towers owned by others.

Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes listed in the Annual Report on Form 10-K as critical to our business operations and the understanding of our results of operations. The listing is not intended to be a comprehensive list. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no need for management’s judgment in their application. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The impact and any associated risks related to these policies on our business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations” where such policies affect reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see Note 2 of our Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2013. Our preparation of our financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of our financial statements, and the reported amounts of revenue and expenses during the reporting periods. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ from those estimates and such differences could be significant.

KEY PERFORMANCE INDICATORS

Non-GAAP Financial Measures

This report contains certain non-GAAP measures, including Segment Operating Profit and Adjusted EBITDA information. We have provided below a description of such non-GAAP measures, a reconciliation of such non-GAAP measures to their most directly comparable GAAP measures and an explanation as to why management utilizes these measures.

24

Segment Operating Profit:

We believe that Segment Operating Profit is an indicator of the operating performance of our site leasing and site development segments and is used to provide management with the ability to monitor the operating results and margin of each segment, while excluding the impact of depreciation, accretion, and amortization, which is largely fixed and non-cash in nature. Segment Operating Profit is not intended to be an alternative measure of revenue or segment gross profit as determined in accordance with GAAP.

Domestic site leasing segment operating profitincreased  $26.3 million for the three months ended June 30, 2014, as compared to the prior year, primarily due to additional profit generated by (i) 298towers acquired and118towers built since April 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments with current tenants which increased the related rent as a result of additional equipment added to our towers in addition to improving control of our site leasing cost of revenue, and the positive impact of our ground lease purchase program.

Domestic site leasing segment operating profitincreased$46.5 million for the six months ended June 30, 2014, as compared to the prior year, primarily due to additional profit generated by (i) 320 towers acquired and 148 towers built since January 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments with current tenants which increased the related rent as a result of additional equipment added to our towers in addition to improving control of our site leasing cost of revenue, and the positive impact of our ground lease purchase program.

International site leasing segment operating profitincreased  $27.0 million for the three months ended June 30, 2014, as compared to the prior year, primarily due to additional profit generated by (i)4,396towers acquired and262towers built since April 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments with current tenants which increased the related rent as a result of additional equipment added to our towers in addition to improving control of our site

leasing cost of revenue, and the positive impact of our ground lease purchase program.The increase in international segment operating profit includes the negative impact of $0.3 million from fluctuations in foreign currency exchange rates as compared to the prior year.

International site leasing segment operating profitincreased$41.0 million for the six months ended June 30, 2014, as compared to the prior year, primarily due to additional profit generated by (i)4,415towers acquired and 294towers built since January 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments with current tenants which increased the related rent as a result of additional equipment added to our towers in addition to improving control of our site leasing cost of revenue, and the positive impact of our ground lease purchase program.The increase in international segment operating profit includes the negative impact of $0.9 million from fluctuations in foreign currency exchange rates as compared to the prior year.

Site development segment operating profit increased  $2.0 million and $3.8 million for the threeand six months ended June 30, 2014,  respectively, as compared to the prior year, primarily due to higher margin carrier direct work performed in the current year, in particular the Sprint 2.5 GHz initiative.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) excluding the impact of non-cash straight-line leasing revenue, non-cash straight-line ground lease expense, non-cash compensation, net loss from extinguishment of debt, other income and expenses, acquisition related expenses, asset impairment and decommission costs, net interest expenses, depreciation, accretion, and amortization, provision (benefit) for taxes, and income from discontinued operations.

We believe that Adjusted EBITDA is an indicator of the financial performance of our core businesses. Adjusted EBITDA is a component of the calculation that has been used by our lenders to determine compliance with certain covenants under our Senior Credit Agreement and the indentures relating to our 8.25% Notes, 5.625% Notes, 5.75% Notes, and 4.875% Notes. Adjusted EBITDA is not intended to be an alternative measure of operating income or gross profit margin as determined in accordance with GAAP.

Revenues:

Domestic site leasing revenuesincreased  $25.4 million for the three months ended June 30, 2014, as compared to the prior year, due largely to (i) revenues from 298 towers acquired and 118 towers built since April 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments which increased the related rent to reflect additional equipment added to our towers.

International site leasing revenues increased  $35.5 million for the three months ended June 30, 2014, as compared to the prior year, due largely to (i) revenues from 4,396 towers acquired and 262 towers built since April 1, 2013 and (ii) organic site leasing growth from new leases, contractual rent escalators, and lease amendments which increased the related rent to reflect additional equipment added to our towers.The increase in international site leasing revenues includes the negative impact of $0.6 million from fluctuations in foreign currency exchange rates as compared to the prior year.

27

Site development revenuesdecreased  $1.8 million for the three months ended June 30, 2014, as compared to the prior year, primarily due to a reduction in the volume of work performed during the quarter for Sprint, which had more activity in the prior year from the Network Vision Initiative than the current year 2.5GHz initiative.

Operating Expenses:

Domestic site leasing cost of revenuesdecreased  $0.9 million for the three months ended June 30, 2014, as compared to the prior year, primarily as a result of a non-recurring property tax adjustment and by the positive impact of our ground lease purchase program, partially offset by the growth in the number of towers owned by us.

International site leasing cost of revenues increased  $8.5 million for the three months ended June 30, 2014, as compared to the prior year, primarily as a result of the growth in the number of towers owned by us, partially offset by the positive impact of our ground lease purchase program.The increase in international site leasing cost of revenues includes the positive impact of $0.3 million from fluctuations in foreign currency exchange rates as compared to the prior year.

Site development cost of revenuesdecreased  $3.9million for the threemonths ended June 30, 2014, as compared to the prior year, as a result of a reduction in the volume of work performed due to the timing of our wireless carrier customers’ initiatives, as well as an increase in higher margin direct work.

Selling, general, and administrative expensesincreased$3.9 million for the three months ended June 30, 2014, as compared to the prior year, primarily as a result of an increase in personnel, salaries, benefits, non-cash compensation, and other expenses due in large part to our continued portfolio expansion.

Acquisition related expensesincreased$0.3 million for the three months ended June 30, 2014, as compared to the prior year, primarily as a result of an increase in acquisition and integration related activities including the Oi S.A. acquisition which closed on March 31, 2014.

Depreciation, accretion, and amortization expenseincreased$19.9 million for the three months ended June 30, 2014, as compared to the prior year, due to the increase in the number of towerswe acquired and built since April 1, 2013.

Operating Income:

Operating incomeincreased  $33.8 million for the three months ended June 30, 2014, as compared to the prior year, primarily due to higher segment operating profit in both the site leasing and site development segments, partially offset by increases in depreciation, accretion, and amortization expense, acquisition related costs, and selling, general, and administrative expenses.

Other Income (Expense):

Interest expenseincreased  $8.4 million due to the higher average principal amount of cash-interest bearing debt outstanding for the three months ended June 30, 2014compared to the prior year, primarily resulting from the issuance of the2013 Tower Securities and 2014 Term Loan, partially offset by the maturity of the 1.875% Notes,full repayment of the 2011 Term Loan and 2012-2 Term Loan, and the settlement of a portion of the 4.0% Notes.

Non-cash interest expense decreased  $3.9 million for the three months ended June 30, 2014,  as compared to the prior year. This decrease primarily reflects the full repayment of the 1.875% Notes and the settlement of a portion of the 4.0% Notes.

Amortization of deferred financing fees increased  $0.4 million for the three months ended June 30, 2014 compared to the prior year, primarily resulting from the issuance of the 2013 Tower Securities and 2014 Term Loan, partially offset by the maturity of the 1.875% Notes and full repayment of the 2011 Term Loan and 2012-2 Term Loan.

Loss from extinguishment of debt increased  $2.6 million for the three months ended June 30, 2014,  as compared to the prior year, primarily due to the write-off of a portion of the related debt discount and deferred financing fees associated with the settlement ofa portion of the 4.0% Notes.

28

Net Loss:

Netlosswas $9.5 millionfor the three months endedJune 30, 2014, a decrease of $26.4 million compared to a loss of $35.9 million in the prior year, primarily due to an increase in our total segment operating profit and a decrease in non-cash interest expense as compared to the prior year. These items were partially offset by increases in selling, general, and administrative expenses, acquisition related costs, depreciation, amortization, and accretion, and interest expense.

Site development cost of revenues decreased  $9.1 million for the six months ended June 30, 2014, as compared to the prior year, as a result of a reduction in the volume of work performed due to the timing of our wireless carrier customers’ initiatives, as well as an increase in higher margin direct work.

Selling, general, and administrative expenses increased  $8.2 million for the six months ended June 30, 2014, as compared to the prior year, primarily as a result of an increase in personnel, salaries, benefits, non-cash compensation, and other expenses due in large part to our continued portfolio expansion.

Acquisition related expenses increased  $3.0 million for the six months ended June 30, 2014, as compared to the prior year, primarily as a result of an increase in acquisition and integration related activities including the Oi S.A. acquisition which closedon March 31, 2014.

Depreciation, accretion, and amortization expense increased  $38.7 million for the six months ended June 30, 2014, as compared to the prior year, due to the increase in the number of towers we acquired and built since January 1, 2013.

Operating Income:

Operating income increased  $44.2 million for the six months ended June 30, 2014, as compared to the prior year, primarily due to higher segment operating profit in both the site leasing and site development segments, partially offset by increases in depreciation, accretion, and amortization expense, acquisition related costs, and selling, general, and administrative expenses.

Other Income (Expense):

Interest expense increased  $14.9 million due to the higher average principal amount of cash-interest bearing debt outstanding for the six months ended June 30, 2014 compared to the prior year, primarily resulting from the issuance of the 2013 Tower Securities and 2014 Term Loan, partially offset by the maturity of the 1.875% Notes,  full repayment of the 2011 Term Loan and 2012-2 Term Loan, and the settlement of a portion of the 4.0% Notes.

Non-cash interest expense decreased  $10.9 million for the six months ended June 30, 2014, as compared to the prior year. This decrease primarily reflects the full repayment of the 1.875% Notes and the settlement of a portion of the 4.0% Notes.

Amortization of deferred financing fees increased  $1.0 million for the six months ended June 30, 2014 compared to the prior year, primarily resulting from the issuance of the 2013 Tower Securities and 2014 Term Loan, partially offset by the maturity of the 1.875% Notes and full repayment of the 2011 Term Loan and 2012-2 Term Loan.

Net Loss:

Net loss was $8.1 millionfor the six months ended June 30, 2014, a decrease of $50.2 million compared to a loss of $58.3 million in the prior year, primarily due to an increase in our total segment operating profit, an increase in other income, and a decrease in non-cash interest expense as compared to the prior year. These items were partially offset by increases in selling, general, and administrative expenses, acquisition related costs, depreciation, amortization, and accretion, and interest expense.

LIQUIDITY AND CAPITAL RESOURCES

SBA Communications Corporation (“SBAC”) is a holding company with no business operations of its own. SBAC’s only significant asset is the outstanding capital stock of SBA Telecommunications LLC (“Telecommunications”), which is also a holding company that owns equity interests in entities that directly or indirectly own all of our domestic and international towers and assets. We conduct all of our business operations through Telecommunications’ subsidiaries. Accordingly, our only source of cash to pay our obligations, other than financings, is distributions with respect to our ownership interest in our subsidiaries from the net earnings and cash flow generated by these subsidiaries.

A summary of our cash flows is as follows:

	For the six months ended
	June 30,
	2014		2013
	(in thousands)
Cash provided by operating activities	$	352,836	$	228,159

Operating Activities

Cash provided by operating activities was $352.8 million for the six months ended June 30, 2014 as compared to $228.2 million for the six months ended June 30, 2013. This increase was primarily due to an increase in segment operating profit from the site leasing and site development operating segments and increases in cash inflows associated with working capital changes partially offset by increased selling, general, and administrative expenses, as well as, increased cash interest payments relating to the higher average amount of cash-interest bearing debt outstanding for the six months ended June 30, 2014 compared to the six monthsended June 30, 2013.

(1) Included in our cash capital expenditures for the six months ended June 30, 2014 is $673.9 million related to our acquisition of 2,007 towers from Oi S.A. which closed on March 31, 2014.

(2) Excludes $5.0 million and $4.9 million spent on ground lease extensions and term easements for the six months ended June 30, 2014 and 2013, respectively.

Subsequent to June 30, 2014, we acquired 11 towers and related assets for $8.1 million in cash.

During all of 2014, inclusive of the capital expenditures made during the six months ended June 30, 2014,  we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and general corporate expenditures of $24.0 million to $29.0 million and discretionary cash capital expenditures, based on current obligations, of $1,732.0 million to $1,762.0 million primarily associated with the Oi acquisition closed March 31, 2014 and the acquisition of an additional 1,641 sites from Oi for R$1.2 billion (or approximately $527.0 million at current exchange rates) expected to close before year-end, as well as new tower construction, additional toweracquisitions, tower augmentations, and ground lease purchases. We expect to fund these cash capital expenditures from cash on hand, cash flow from operations, and borrowings under the Revolving Credit Facility or new financings. The exact amount of our future cash capital expenditures will depend on a number of factors including amounts necessary to support our tower portfolio, our new tower build and acquisition programs, and our ground lease purchase program.

Financing Activities

During the first quarter of 2014, our subsidiary, SBA Senior Finance II, obtained a new senior secured term loan with an initial aggregate principal amount of $1.5 billion that was issued at 99.75% of par value and matures on March 24, 2021 (the “2014 Term Loan”). Net proceeds from the 2014 Term Loan were used to (1) repay in full the remaining $180.5 million balance of the 2011 Term Loan, (2) repay in full the remaining $110.0 million balance of the 2012-2 Term Loan, (3) repay the $390.0 million outstanding balance under our Revolving Credit Facility, and (4) pay the cash consideration in connection with theOi S.A. acquisition which closed on March 31, 2014. The remaining net proceeds were used for general corporate purposes.

During the six months ended June 30, 2014, we borrowed $275.0 million and repaid $390.0 million under the Revolving Credit Facility. As of June 30, 2014, we had $100.0 million outstanding under the $770.0 million Revolving Credit Facility. Subsequent to June 30, 2014, we repaid the remaining $100.0 million outstanding balance under the Revolving Credit Facility with proceeds from the 4.875% Senior Notes (see below). As of the date of this filing, no amounts were outstanding under the Revolving Credit Facility, and the amount available based on specified covenants under the facility was $720.0 million.

During the second quarter of 2014, we received conversion notices totaling $127.9 million in principal of the 4.0% Notes and settled $121.5 million in principal of the 4.0% Notes for $121.5 million in cash and 2.7 million shares of our Class A common stock with the remaining to be settled in the third quarter of 2014. Concurrently with the settlement of our conversion obligation, we settled the convertible note hedges receiving 2.7 million shares of our Class A common stock. As a result, our outstanding share count has not been and will not be impacted by the conversion of these notes under the current settlement election. Subsequent to the end of the second quarter, we received additional conversion notices totaling $4.6 million of principal which will settle in the third quarter of 2014.

32

During the second quarter, we paid $276.2 million to early settle approximately 30% of the outstanding warrants sold in connection with the issuance of the 4.0% Notes, representing approximately 4.9 million underlying shares of Class A common stock, scheduled to mature in the first quarter of 2015. Subsequent to the second quarter, we paid $66.5 million to early settle approximately 7.5% of the original total outstanding warrants, representing approximately 1.2 million underlying shares, scheduled to mature in the first quarter of 2015.

On July 1, 2014, we issued $750.0 million aggregate principal amount of our 4.875% Senior Notes due 2022 (the  “4.875% Notes”). The 4.875% Notes were issued at 99.178% of par value. Interest on the 4.875% Notes is payable semi-annually on January 15 and July 15 of each year beginning January 15, 2015. The 4.875% Notes mature on July 15, 2022. Net proceeds from the 4.875% Notes will be used to redeem all of the 8.25% Notes due 2019 including the associated call premium and pay the conversion obligations with respect to approximately $121.0 million aggregate principal amount of our 4.0% Convertible Senior Notes due 2014 (the “4.0% Notes”). All remaining net proceeds will be used for general corporate purposes.

During the six months ended June 30, 2014, we did not repurchase any shares of our Class A common stock under our stock repurchase program. As of June 30, 2014, we had a remaining authorization to repurchase $150.0 million of Class A common stock under our current $300.0 million stock repurchase program.

Registration Statements

We have on file with the Commission a shelf registration statement on Form S-4 registering shares of Class A common stock that we may issue in connection with the acquisition of wireless communication towers or antenna sites and related assets or companies who own wireless communication towers, antenna sites, or related assets. During the six months ended June 30, 2014, we did not issue any shares of Class A common stock under this registration statement. As of June 30, 2014, we had approximately 1.7 million shares of Class A common stock remaining under this shelf registration statement.

On February 27, 2012, we filed with the Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR. This registration statement enables us to issue shares of our Class A common stock, preferred stock or debt securities either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules governing automatic shelf registration statements, we will file a prospectus supplement and advise the Commission of the amount and type of securities each time we issue securities under this registration statement. No shares were issued in 2013 or the first and second quarters of 2014.

Debt Instruments and Debt Service Requirements

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. As of June 30, 2014, the Revolving Credit Facility consisted of a revolving loan under which up to $770.0 million aggregate principal amount may be borrowed, repaid and redrawn, subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest at the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated TotalDebt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. If not earlier terminated by SBA Senior Finance II LLC (“SBA Senior Finance II”), a subsidiary of the Company, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, May 9, 2017. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A per annum commitment fee of 0.375% to 0.5% of the unused commitments under the Revolving Credit Facility is charged based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Senior Credit Agreement).

SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be reflective of the total amounts outstanding during such period.

During the three and six months ended June 30, 2014,  we borrowed $100.0million and $275.0 million, respectively, under the Revolving Credit Facility. During the six months ended June 30, 2014, we repaid $390.0 million of the outstanding balance under the Revolving Credit Facility. As of June 30, 2014,  $100.0 million was outstanding under the Revolving Credit Facility. Subsequent to June 30, 2014, we repaid the remaining $100.0 million outstanding balance under the Revolving Credit Facility with proceeds from the issuance of the 4.875% Notes (defined below). As of the date of this filing, no amounts were outstanding under the Revolving Credit Facility, and the amount available based on specified covenants under the facilitywas $720.0 million.

33

On February 7, 2014, SBA Senior Finance II entered into a Second Amended and Restated Credit Agreement (as amended and restated, the “Senior Credit Agreement”) with several banks and other financial institutions or entities from time to time parties to the Senior Credit Agreement to, among other things, obtain a $1.5 billion senior secured term loan (the “2014 Term Loan”) and to amend certain terms of the existing senior credit agreement. In addition to providing for the 2014 Term Loan, the Senior Credit Agreement was amended to, among other things, amend the terms of certain events of default, modify certain negative covenants and remove the parent financial maintenance leverage covenant to reflect the increased size of SBA Senior Finance II and its restricted subsidiaries.  All other material terms of the Senior Credit Agreement, as it existed prior to February 7, 2014, remained unchanged.

(2) The anticipated repayment date and the final maturity date for the 2010-1 Tower Securities is April 15, 2015 and April 16, 2040, respectively.

The anticipated repayment date and the final maturity date for the 2010-2 Tower Securities is April 17, 2017 and April 15, 2042, respectively.

The anticipated repayment date and the final maturity date for the 2012-1 Tower Securities is December 15, 2017 and December 15, 2042, respectively.

The anticipated repayment date and the final maturity date for the 2013-1C Tower Securities is April 17, 2018 and April 17, 2043, respectively.

The anticipated repayment date and the final maturity date for the 2013-1D Tower Securities is April 17, 2018 and April 17, 2043, respectively.

Our current primary market risk exposure is (1) our ability to refinance our debt at commercially reasonable rates, if at all, (2) interest rate risk relating to our ability to meet financial covenants, and (3)interest rate risk relating to the impact of interest rate movements on our 2012-1 Term Loan and 2014 Term Loan and any borrowings that we may incur under our Revolving Credit

39

Facility, which are at floating rates. We manage the interest rate risk on our outstanding debt through our large percentage of fixed rate debt. While we cannot predict our ability to refinance existing debt or the impact interest rate movements will have on our existing debt, we continue to evaluate our financial position on an ongoing basis. In addition, in connection with our convertible notes, we are subject to market risk associated with the market price of our common stock.

We are exposed to market risk from changes in foreign currency exchange rates in connection with our operations in Brazil, Canada, Costa Rica, Guatemala, and Nicaragua. In each of these countries, we pay most of our selling, general, and administrative expenses and a portion of our operating expenses, such as taxes and utilities incurred in the country in local currency. In addition, in Brazil and Canada, we receive significantly all of our revenue and pay significantly all of our operating expenses in local currency. All transactions denominated in currencies other than the U.S. Dollar are reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of Accumulated other comprehensive income (loss). For the six months ended June 30, 2014, approximately 8.7% of our revenues and approximately10.0% of our total operating expenses were denominated in foreign currencies.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in the Brazilian Reais from the quoted foreign currency exchange rates at June 30, 2014. As of June 30, 2014, the analysis indicated that such an adverse movement would have caused our revenues and operating results to fluctuate by less than 1% for the six months ended June 30, 2014.

Special Note Regarding Forward-Looking Statements

This quarterly report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements concern expectations, beliefs, projections, plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Specifically, this quarterly report contains forward-looking statements regarding:

•our expectations on the future growth and financial health of the wireless industry and the industry participants, and the drivers of such growth;

•our beliefs regarding our ability to capture and capitalize on industry growth and the impact of such growth on our financial and operational results;

•our expectations regarding the opportunities in the international wireless markets in which we currently operate or have targeted for growth, our beliefs regarding how we can capitalize on such opportunities, and our intent to continue expanding internationally through new builds and acquisitions;

•our belief that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional antenna space on our towers due to increasing minutes of network use and data transfer, network expansion and network coverage requirements;

•our belief that our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs, and minimal non-discretionary capital expenditures;

•our expectation that, due to the relatively young age and mix of our tower portfolio, future expenditures required to maintain these towers will be minimal;

•our expectation that we will grow our cash flows by adding tenants to our towers at minimal incremental costs and executing monetary amendments;

•our intent to grow our tower portfolio, domestically and internationally;

•our expectation that we will continue our ground lease purchase program and the estimates of the impact of such program on our financial results;

•our expectation that we will continue to incur losses;

40

•our expectations regarding our future cash capital expenditures, both discretionary and non-discretionary, including expenditures required to maintain, improve, and modify our towers, ground lease purchases, and general corporate expenditures, and the source of funds for these expenditures;

•our intended use of our liquidity;

•our expectations regarding our annual debt service in 2014 and thereafter, and our belief that our cash on hand, cash flows from operations for the next twelve months and availability under our Revolving Credit Facility will be sufficient to service our outstanding debt during the next twelve months;

•our belief regarding our credit risk; and

•our estimates regarding certain accounting and tax matters.

These forward-looking statements reflect our current views about future events and are subject to risks, uncertainties and assumptions. We wish to caution readers that certain important factors may have affected and could in the future affect our actual results and could cause actual results to differ significantly from those expressed in any forward-looking statement. The most important factors that could prevent us from achieving our goals, and cause the assumptions underlying forward-looking statements and the actual results to differ materially from those expressed in or implied by those forward-looking statements include, but are not limited to, the following:

•the impact of consolidation among wireless service providers on our leasing revenue;

•our ability to continue to comply with covenants and the terms of our credit instruments and our ability to obtain additional financing to fund our capital expenditures;

•our ability to successfully manage the risks associated with international operations, including risks relating to political or economic conditions, tax laws, currency restrictions, legal or judicial systems, and land ownership;

•our ability to successfully manage the risks associated with our acquisition initiatives, including our ability to effectively integrate acquired towers into our business and to achieve the financial results projected in our valuation models for the acquired towers;

•developments in the wireless communications industry in general, and for wireless communications infrastructure providers in particular, that may slow growth or affect the willingness or ability of the wireless service providers to expend capital to fund network expansion or enhancements;

•our ability to secure as many site leasing tenants as anticipated, recognize our expected economies of scale with respect to new tenants on our towers, and retain current leases on towers;  

•our ability to secure and deliver anticipated services business at contemplated margins;

•our ability to build new towers, including our ability to identify and acquire land that would be attractive for our clients and to successfully and timely address zoning, permitting, weather, availability of labor and supplies and other issues that arise in connection with the building of new towers;

•competition for the acquisition of towers and other factors that may adversely affect our ability to purchase towers that meet our investment criteria and are available at prices which we believe will be accretive to our shareholders and allow us to maintain our long-term target leverage ratios;

•our ability to protect our rights to the land under our towers, and our ability to acquire land underneath our towers on terms that are accretive;

•our ability to sufficiently increase our revenues and maintain expenses and cash capital expenditures at appropriate levels to permit us to meet our anticipated uses of liquidity for operations, debt service and estimated portfolio growth;

41

•our ability to successfully estimate the impact of regulatory and litigation matters;

•our ability to successfully estimate the impact of certain accounting and tax matters, including the effect on our company of adopting certain accounting pronouncements and the availability of sufficient net operating losses to offset future taxable income;

•natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage;

•a decrease in demand for our towers; and

•the introduction of new technologies or changes in a tenant’s business model that may make our tower leasing business less desirable to potential tenants.

ITEM 4. CONTROLS AND PROCEDURES

In order to ensure that the information we must disclose in our filings with the SEC is recorded, processed, summarized and reported on a timely basis, we have formalized our disclosure controls and procedures.

Basis of Presentation

1.BASIS OF PRESENTATION

The accompanying consolidated financial statements should be read in conjunction with the Annual Report on Form 10-K for the fiscal year ended December 31, 2013 for SBA Communications Corporation and its subsidiaries (the “Company”). These financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, omit or condense certain footnotes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States. In the opinion of the Company’s management, all adjustments (consisting of normal recurring accruals) considered necessary for fair financial statement presentation have been made. The results of operations for an interim period may not give a true indication of the results for the year. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in consolidated financial statements and accompanying notes. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial statements and accompanying notes, the actual amount of such estimates, when known, will vary from these estimates.

Foreign Currency Translation 

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive income (loss) in shareholders’ equity.

Income Taxes

14.INCOME TAXES

During the three months ended June 30, 2014, the Company had federal and state taxable income which was offset by net operating losses for the six months ended June 30, 2014.  The Company had U.S. taxable losses during the threemonths ended June 30, 2014 and 2013 and for the six months ended June 30, 2013, and, as a result, federal and state net operating loss carry-forwards have been generated. The U.S. federal and state net operating loss carry-forwards of the Company have a full valuation allowance as management believes it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to realize the losses. A foreign tax provision is recognized because certain international subsidiaries of the Company have profitable operations or a net deferred tax liability position.

The Company’s credit risks consist primarily of accounts receivable with national, regional, and local wireless service providers and federal and state government agencies. The Company performs periodic credit evaluations of its customers’ financial condition and provides allowances for doubtful accounts, as required, based upon factors surrounding the credit risk of specific customers, historical trends, and other information. The Company generally does not require collateral on its lease agreements or site development contracts.

The following is a list of significant customers (representing at least 10% of segment revenues for the periods reported) and the percentage of total segment revenues for the specified time periods derived from such customers.

Surety bonds and workers compensation		9,342		8,991	Other assets - noncurrent
Total restricted cash	$	45,761	$	56,296

Pursuant to the terms of the Tower Securities (see Note 11), the Company is required to establish a securitization escrow account, held by an indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to towers, (3) trustee and servicing expenses, and (4) management fees and to reserve a portion of advance rents from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 11) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as restricted cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily relates to the Company’s tower removal obligations. As of June 30, 2014, the Company had $40.7 million in surety bonds and payment and performance bonds for which it was only required to post $3.1 million in collateral. As of December 31, 2013, the Company had $42.0 million in surety, payment and performance bonds for which it was only required to post $6.1 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. As of June 30, 2014 and December 31, 2013, the Company had also pledged $2.6 million and $2.3 million, respectively, as collateral related to its workers compensation policy.

Segment Data

15.SEGMENT DATA

The Company operates principally in two business segments: site leasing and site development. The Company’s reportable segments are strategic business units that offer different services. They are managed separately based on the fundamental differences in their operations. The site leasing segment includes results of the managed and sublease businesses. The site development segment includes the results of both consulting and construction related activities.

Commencing in the second quarter of 2014, the Company expanded the presentation of its site leasing business into two reporting segments, domestic site leasing and international site leasing as a result of its international site leasing revenues exceeding 10% of total revenues. All prior periods have been restated to conform to the current year presentation.

Revenues, cost of revenues (exclusive of depreciation, accretion and amortization), capital expenditures (including assets acquired through the issuance of shares of the Company’s Class A common stock) and identifiable assets pertaining to the segments in which the Company continues to operate are presented below:

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. As of June 30, 2014, the Revolving Credit Facility consisted of a revolving loan under which up to$770.0million aggregate principal amount may be borrowed, repaid and redrawn, subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest at the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated TotalDebt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. If not earlier terminated by SBA Senior Finance II LLC (“SBA Senior Finance II”), a subsidiary of the Company, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, May 9, 2017. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A per annum commitment fee of 0.375% to 0.5% of the unused commitments under the Revolving Credit Facility is charged based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Senior Credit Agreement). SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be reflective of the total amounts outstanding during such period.

During the three and six months ended June 30, 2014, the Company borrowed $100.0 million and $275.0 million, respectively, under the Revolving Credit Facility. During the six months ended June 30, 2014, the Company repaid $390.0 million of the outstanding balance under the Revolving Credit Facility.

On February 7, 2014, SBA Senior Finance II entered into a Second Amended and Restated Credit Agreement (as amended and restated, the “Senior Credit Agreement”) with several banks and other financial institutions or entities from time to time parties to the Senior Credit Agreement to, among other things, obtain a $1.5 billion senior secured term loan(the “2014 Term Loan”) and to amend certain terms of the existing senior credit agreement. In addition to providing for the 2014 Term Loan, the Senior Credit Agreement was amended to, among other things, amend the terms of certain events of default, modify certain negative covenants and remove the parent financial maintenance leverage covenant to reflect the increased size of SBA Senior Finance II and its restricted subsidiaries.  All other material terms of the Senior Credit Agreement, as it existed prior to February 7, 2014, remained unchanged.

Concurrently with the pricing of the 4.0% Notes, the Company entered into convertible note hedge and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 4.0% Notes is $30.38 per share of the Company’s Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share.

	(in thousands)
Principal balance	$	378,370	$	499,944
Debt discount		(8,170)		(31,550)
Carrying value	$	370,200	$	468,394

During the  three and six months ended June 30, 2014, the 4.0% Notes were convertible based on the fact that the closing price per share of the Company’s Class A common stock exceeded $39.49 for at least 20 trading days during the 30 consecutive trading day period ending on March 31, 2014 and December 31, 2013, respectively, and remain convertible as of the date of this filing.  During the three and six months ended June 30, 2014,  holders of the 4.0% Notes converted $121.5 million and $121.6 million, respectively, in principal amount of 4.0% Notes. The Company settled its conversion obligation through the payment of the principal amount in cash and the issuance of 2.7 million shares of its Class A common stock during the three and six months ended June 30, 2014.  Concurrently with these conversions, the related convertible note hedges were settled, and the Company received 2.7 million shares of its Class A common stock, of which 0.1 million shares were received subsequent to June 30, 2014.  As a result, the Company’s outstanding share count has not been impacted by the conversion of these notes. In addition, the Company received conversion notices totaling $11.3 million in principal amount of the 4.0% Notes which will settle during the third quarter of 2014 for cash and shares of its Class A common stock.

During the three months ended June 30, 2014, the Company paid $276.2 million to early settle approximately 30% of the outstanding warrants sold in connection with the issuance of the 4.0% Notes, representing approximately 4.9 million underlying shares of Class A common stock, scheduled to mature in the first quarter of 2015. Subsequent to June 30, 2014, the Company paid $66.5 million to early settle approximately 7.5% of the original total outstanding warrants, representing approximately 1.2 million underlying shares, scheduled to mature in the first quarter of 2015.

Acquisitions

5.ACQUISITIONS

The Company acquired 45 communication sites and related assets and liabilitiesand the rights to manage 4 additional communication sites during the three months ended June 30, 2014.These acquisitions were not significant to the Company and, accordingly, a preliminary estimate of the fair value of the assets acquired and liabilities assumed has not been presented. The Company evaluates all acquisitions after the applicable closing date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed by major balance sheet caption, as well as the separate recognition of intangible assets from goodwill if certain criteria are met.

The following table summarizes all of the Company’s cash acquisition capital expenditures:

	For the three months				For the six months

Total cash acquisition capital expenditures	$	39,162	$	46,268	$	967,474	$	255,409

(1) In addition, the Company paid $3.7 million and $3.1 million for ground lease extensions and term easements during the three months ended June 30, 2014 and 2013, respectively, and $5.0 million and $4.9 million for ground lease extensions during the six months ended June 30, 2014 and 2013, respectively. The Company recorded these amounts in prepaid rent on its Consolidated Balance Sheets.

Subsequent to June 30, 2014, the Company acquired 11 communication sites and related assets and liabilities and the rights to manage 1 additional communication site for $8.1 million in cash.

13.STOCK-BASED COMPENSATION

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a combination of historical data and historical volatility to establish the expected volatility. Historical data is used to estimate the expected option life and the expected forfeiture rate. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. The following assumptions were used to estimate the fair value of options granted using the Black-Scholes option-pricing model:

	For the six months ended
	June 30,
	2014	2013
Risk free interest rate	1.15% - 1.325%	0.51% - 1.03%

Fair Value Measurements [Abstract]

Fair Value Measurements

2.FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis— The Company’s earnouts related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs. Level 3 valuations rely on unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The Company determines the fair value of acquisition-related contingent consideration and any subsequent changes in fair value using a discounted probability-weighted approach using Level 3 inputs. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on historical internal observations related to the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its obligation if the performance targets contained in various acquisition agreements were met was $19.8 million and $30.1 million as of June 30, 2014 and December 31, 2013, respectively, which the Company recorded in accrued expenses on its Consolidated Balance Sheets. The maximum potential obligation related to the performance targets was $31.6 million as of June 30, 2014.

The following summarizes the activity of the accrued earnouts:

Items Measured at Fair Value on a Nonrecurring Basis— The Company’s long-lived assets, intangibles, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. The Company considers many factors and makes certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. The fair value of the long-lived assets, intangibles, and asset retirement obligations is calculated using a discounted cash flow model. During the three and six months ended June 30, 2014, the Company recognized an impairment charge of $4.0 million and $7.6 million, respectively. The impairment charge includes the write off of $3.3 million and $5.6 million in carrying value of decommissioned towers and other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and six months ended June 30, 2014, respectively. During the three and six months ended June 30, 2013, the Company recognized an impairment charge of $6.5 million and $10.2 million, respectively. The impairment charge includes the write off of $6.1 million and $7.4 million in carrying value of decommissioned towers and other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and six months ended June 30, 2013, respectively. These write offs result from the Company’s analysis that the future cash flows from certain towers would not recover the carrying value of the investment in those towers. Impairment charges and the related impaired assets relate to the Company’s site leasing operating segment.

Fair Value of Financial Instruments— The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments. Short-term investments consisted of $5.6 million and $5.2 million in certificate of deposits, as of June 30, 2014 and December 31, 2013, respectively. The Company’s estimate of the fair value of its held-to-maturity investments in treasury and corporate bonds, including current portion, are based primarily upon Level 1 reported market values. As of June 30, 2014, the carrying value and fair value of the held-to-maturity investments, including current portion, were $1.2 million and $1.3 million, respectively. As of December 31, 2013, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.1 million and $1.3 million, respectively.

The Company determines fair value of its debt instruments utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to approximate the carrying value because the interest payments are based on Eurodollar rates that reset every month. The Company does not believe its credit risk has changed materially from the date the applicable Eurodollar Rate plus 187.5 basis points was set for the Revolving Credit Facility. The following table reflects fair values, principal balances, and carrying values of the Company’s debt instruments (see Note 11).

Shareholders' Equity

6 Months Ended

Shareholders' Equity [Abstract]

Shareholders' Equity

12.SHAREHOLDERS’ EQUITY

Common Stock equivalents

The Company has potential common stock equivalents related to its outstanding stock options (see Note 13), restricted stock units, and the 4.0% Notes and related warrants (see Note 11). These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive for each of the three and six months ended June 30, 2014 and 2013, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for each period presented. 

Stock Repurchases

The Company’s Board of Directors authorized a stock repurchase program on April 27, 2011. This program authorizes the Company to purchase, from time to time, up to $300.0 million of the Company’s outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by the Company’s Board of Directors at any time in the Company’s sole discretion.

During the six months ended June 30, 2014, the Company did not repurchase any shares in conjunction with the stock repurchase program. As of June 30, 2014, the Company had a remaining authorization to repurchase an additional $150.0 million of its common stock under its current $300.0 million stock repurchase program.
