AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.    Description of Business, Basis of Presentation and Accounting Policies

Business—American Tower Corporation is, through its various subsidiaries (collectively, “ATC” or the “Company”), one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. The Company’s primary business is the leasing of space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. The Company also manages rooftop and tower sites for property owners, operates in-building and outdoor distributed antenna system (“DAS”) networks, holds property interests under third-party communications sites and provides network development services that primarily support its rental and management operations.

ATC is a holding company that conducts its operations through its directly and indirectly owned subsidiaries and its joint ventures. ATC’s principal domestic operating subsidiaries are American Towers LLC and SpectraSite Communications, LLC. ATC conducts its international operations primarily through its subsidiary, American Tower International, Inc., which in turn conducts operations through its various international holding and operating subsidiaries and joint ventures.

The Company operates as a real estate investment trust for U.S. federal income tax purposes (“REIT”) and, therefore, is generally not subject to U.S. federal income taxes on its income and gains that it distributes to its stockholders, including the income derived from leasing space on its towers. However, the Company remains obligated to pay income taxes on earnings from its taxable REIT subsidiaries (“TRSs”). In addition, the Company’s international assets and operations, including those designated as direct or indirect qualified REIT subsidiaries or other disregarded entities of a REIT (collectively, “QRSs”), continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. As of March 31, 2015, the Company’s QRSs included its domestic tower leasing business, most of its operations in Costa Rica, Germany and Mexico and a portion of its network development services segment and indoor DAS networks business.

On March 27, 2015, the Company significantly expanded its domestic portfolio by obtaining the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon Communications Inc. (“Verizon”) in the United States (the “Verizon Transaction”).

The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. The financial information included herein is unaudited; however, the Company believes that all adjustments (consisting primarily of normal recurring adjustments) considered necessary for a fair presentation of the Company’s financial position and results of operations for such periods have been included. These condensed consolidated financial statements and related notes should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Principles of Consolidation and Basis of Presentation—The accompanying condensed consolidated financial statements include the accounts of the Company and those entities in which it has a controlling interest. Investments in entities that the Company does not control are accounted for using the equity or cost method, depending upon the Company’s ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions have been eliminated.

Significant Accounting Policies and Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

be material to the accompanying condensed consolidated financial statements. The significant estimates in the accompanying condensed consolidated financial statements include impairment of long-lived assets (including goodwill), asset retirement obligations, revenue recognition, rent expense, stock-based compensation, income taxes and accounting for business combinations and acquisitions of assets. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued as additional evidence for certain estimates or to identify matters that require additional disclosure.

Accounting Standards Updates—In May 2014, the Financial Accounting Standards Board (the “FASB”) issued new revenue recognition guidance, which requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP and will become effective on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method and leases are not included in the scope of this standard. The Company is evaluating the impact this standard will have on its financial statements.

In June 2014, the FASB issued stock-based compensation guidance, which requires a performance target that could be achieved after the requisite service period be treated as a performance condition that affects vesting, rather than a condition that affects the grant-date fair value. The Company early adopted this guidance during the three months ended March 31, 2015, and it did not have a material effect on the Company’s financial statements.

In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. The guidance requires debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts and premiums. The update requires retrospective application and the update is effective for annual reporting periods beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material effect on its financial statements.

(2) Acquired network location intangibles are amortized over the shorter of the term of the corresponding ground lease taking into consideration lease renewal options and residual value or up to 20 years, as the Company considers these intangibles to be directly related to the tower assets.

(3) Deferred financing costs are amortized over the term of the respective debt instruments to which they relate using the effective interest method. This amortization is included in Interest expense rather than in Depreciation, amortization and accretion expense.

The acquired network location intangibles represent the value to the Company of the incremental revenue growth which could potentially be obtained from leasing the excess capacity on acquired communications sites. The acquired customer-related intangibles typically represent the value to the Company of customer contracts and relationships in place at the time of an acquisition, including assumptions regarding estimated renewals.

The Company amortizes its acquired network location intangibles and customer-related intangibles on a straight-line basis over their estimated useful lives. As of March 31, 2015, the remaining weighted average amortization period of the Company’s intangible assets, excluding deferred financing costs and the TV Azteca Economic Rights detailed in note 5 to the Company’s consolidated financial statements included in its Annual

6.    Derivative Financial Instruments

Certain of the Company’s foreign subsidiaries have entered into interest rate swap agreements, which have been designated as cash flow hedges, to manage exposure to variability in interest rates on debt.

South Africa

One of the Company’s South African subsidiaries has 15 interest rate swap agreements outstanding, which mature on the earlier of termination of the underlying debt or March 31, 2020. These swap agreements provide that the Company pay a fixed interest rate ranging from 6.09% to 7.83% and receive variable interest at the three-month Johannesburg Interbank Agreed Rate (JIBAR) over the term of the interest rate swap agreements. The notional value is reduced in accordance with the repayment schedule under the related credit agreement.

Colombia

In connection with entering into a Colombian Peso (“COP”) denominated credit facility in October 2014 (the “Colombian Credit Facility”), one of the Company’s Colombian subsidiaries entered into an interest rate swap agreement with certain of the lenders under the Colombian Credit Facility. These swap agreement matures on the earlier of termination of the underlying debt or April 24, 2021 and provides that the Company pay a fixed interest rate of 5.74% and receive variable interest at the three-month Inter-bank Rate (“IBR”) over the term of the agreement. The notional value is reduced in accordance with the repayment schedule under the Colombian Credit Facility.

The notional amount and fair value of the interest rate swap agreements were as follows (in thousands):

For additional information on the Company’s interest rate swap agreements, see note 7.

7.    Fair Value Measurements

The Company determines the fair value of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Below are the three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Items Measured at Fair Value on a Recurring Basis—The fair value of the Company’s financial assets and liabilities that are required to be measured on a recurring basis at fair value is as follows (in thousands):

	March 31, 2015

Interest rate swap agreements		$	647			$	647

(1) Consists of highly liquid investments with original maturities in excess of three months.

Interest Rate Swap Agreements

The fair value of the Company’s interest rate swap agreements is determined using pricing models with inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data. Fair valuations of the swap agreements reflect the value of the instrument including the values associated with counterparty risk, the Company’s own credit standing and the value of the net credit differential between the counterparties to the derivative contract.

Acquisition-Related Contingent Consideration

Acquisition-related contingent consideration is initially measured and recorded at fair value as an element of consideration paid in connection with an acquisition with subsequent adjustments recognized in Other operating expenses in the condensed consolidated statements of operations. The Company determines the fair value of acquisition-related contingent consideration, and any subsequent changes in fair value, using a discounted probability-weighted approach. This approach takes into consideration Level 3 unobservable inputs including probability assessments of expected future cash flows over the period in which the obligation is expected to be settled and applies a discount factor that captures the uncertainties associated with the obligation. Changes in these unobservable inputs could significantly impact the fair value of the liabilities recorded in the accompanying condensed consolidated balance sheets and adjustments recorded in the condensed consolidated statements of operations.

As of March 31, 2015, the Company estimated the value of all potential acquisition-related contingent consideration required payments to be between zero and $38.4 million. During the three months ended March 31, 2015 and 2014, the fair value of the contingent consideration changed as follows (in thousands):

	2015			2014
Balance as of January 1	$	28,524		$	31,890
Additions		1,194			—

Items Measured at Fair Value on a Nonrecurring Basis

Assets Held and Used—The Company’s long-lived assets are measured at fair value on a nonrecurring basis using Level 3 inputs. During the three months ended March 31, 2015 and 2014, the Company did not record any asset impairment charges.

There were no other items measured at fair value on a nonrecurring basis during the three months ended March 31, 2015.

During the year ended December 31, 2014, NII Holdings, Inc. (“NII”), a U.S. corporation, filed for Chapter 11 bankruptcy protection on behalf of itself and certain of its subsidiaries. NII is the ultimate parent company of certain operating subsidiaries in Brazil, Chile and Mexico that collectively represented approximately 5% of the Company’s consolidated revenues for the three months ended March 31, 2015. None of these subsidiaries were included in NII’s Chapter 11 filing. The Company did not identify any indicators of impairment as of March 31, 2015.

Fair Value of Financial Instruments—The Company’s financial instruments for which the carrying value reasonably approximates fair value at March 31, 2015 and December 31, 2014 included cash and cash equivalents, restricted cash, accounts receivable and accounts payable. The Company’s estimates of fair value of its long-term obligations, including the current portion, are based primarily upon reported market values. For long-term debt not actively traded, fair value is estimated using either indicative price quotes or a discounted cash flow analysis using rates for debt with similar terms and maturities. As of March 31, 2015, the carrying value and fair value of long-term obligations, including the current portion, were $15.7 billion and $16.3 billion, respectively, of which $9.2 billion was measured using Level 1 inputs and $7.1 billion was measured using Level 2 inputs. As of December 31, 2014, the carrying value and fair value of long-term obligations, including the current portion, were $14.6 billion and $15.0 billion, respectively, of which $9.7 billion was measured using Level 1 inputs and $5.3 billion was measured using Level 2 inputs.

Losses on cash flow hedges have been reclassified into Interest expense in the accompanying condensed consolidated statements of operations and the associated tax effect of less than $0.1 million for each of the three months ended March 31, 2015 and 2014, respectively, is included in Income tax provision.

9.    Income Taxes

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year. Cumulative adjustments to the Company’s estimate are recorded in the interim period in which a change in the estimated annual effective tax rate is determined. As a REIT, the Company continues to be subject to income taxes on the income of its TRSs and income taxation in foreign jurisdictions where it conducts international operations. Under the provisions of the Internal Revenue Code of 1986, as amended, the Company may deduct amounts distributed to stockholders against the income generated in its QRSs. The Company is able to offset income in both its TRSs and QRSs by utilizing their respective net operating losses. In addition, in 2013 the Company acquired MIP Tower Holdings LLC (“MIPT”), which has been organized and has qualified as a REIT. For so long as MIPT continues to elect separate REIT status, it is independently subject to, and must comply with, the same REIT requirements that the Company must satisfy in order to qualify for taxation as a REIT.

The Company provides valuation allowances if, based on the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.

As of March 31, 2015 and December 31, 2014, the total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was approximately $30.8 million and $31.9 million, respectively. The decrease in the amount of unrecognized tax benefits during the three months ended March 31, 2015 was primarily attributable to fluctuations in foreign currency exchange rates, partially offset by additions to the Company’s existing tax positions. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, as described in note 14 to the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2014. The impact of the amount of such changes to previously recorded uncertain tax positions could range from zero to $16.2 million.

The Company recorded penalties and income tax-related interest expense during the three months ended March 31, 2015 and 2014 of $0.9 million and $1.3 million, respectively. As of March 31, 2015 and December 31, 2014, the total amount of accrued income tax-related interest and penalties included in Other non-current liabilities in the condensed consolidated balance sheets was $24.0 million and $24.9 million, respectively.

10.    Stock-Based Compensation

The Company recognized stock-based compensation expense during the three months ended March 31, 2015 and 2014 of $29.9 million and $24.6 million, respectively. The Company capitalized $0.5 million and $0.4 million of stock-based compensation expense as property and equipment during the three months ended March 31, 2015 and 2014, respectively.

Summary of Stock-Based Compensation Plans—The Company maintains equity incentive plans that provide for the grant of stock-based awards to its directors, officers and employees. The 2007 Equity Incentive Plan (the “2007 Plan”) provides for the grant of non-qualified and incentive stock options, as well as restricted stock units, restricted stock and other stock-based awards. Exercise prices in the case of non-qualified and incentive stock options are not less than the fair value of the underlying common stock on the date of grant. Equity awards typically vest ratably over various periods, generally four years for time-based restricted stock units (“RSUs”) and stock options and three years for performance-based restricted stock units (“PSUs”). Stock options generally expire ten years from the date of grant. As of March 31, 2015, the Company had the ability to grant stock-based awards with respect to an aggregate of 11.5 million shares of common stock under the 2007 Plan.

The Company’s Compensation Committee adopted a death, disability and retirement benefits program in connection with equity awards granted on or after January 1, 2013, that provides for accelerated vesting and extended exercise periods of stock options and restricted stock units upon an employee’s death or permanent disability, or upon an employee’s qualified retirement, provided certain eligibility criteria are met. Accordingly, for grants made on or after January 1, 2013, the Company recognizes compensation expense for stock options and RSUs over the shorter of (i) the four-year vesting period or (ii) the period from the date of grant to the date the employee becomes eligible for such retirement benefits, which may occur upon grant; and recognizes compensation expense for PSUs over the three-year vesting period, subject to adjustment based on the date the employee becomes eligible for such retirement benefits.

Stock Options—The Company’s option activity for the three months ended March 31, 2015 was as follows:

	Number of Options
Outstanding as of January 1, 2015		6,508,435
Granted		1,994,079
Exercised		(88,310	)
Forfeited		(38,911	)
Expired		(1,200	)
Outstanding as of March 31, 2015		8,374,093

The fair value of each option granted during the three months ended March 31, 2015 was estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions noted in the table below.

Key assumptions used to apply this pricing model are as follows:

Range of risk-free interest rate	1.57%-1.62%
Weighted average risk-free interest rate	1.62%
Expected life of option grants	4.5 years
Range of expected volatility of underlying stock price	21.09%-21.20%
Weighted average expected volatility of underlying stock price	21.09%
Range of expected annual dividend yield	1.50%-1.85%

Restricted Stock Units—As of March 31, 2015, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $116.0 million and is expected to be recognized over a weighted average period of approximately three years.

Performance-Based Restricted Stock Units—During the three months ended March 31, 2015, the Company granted an aggregate of 70,135 PSUs to its executive officers and established the performance metric for this award. Threshold, target and maximum parameters were established for the metric for each year in the three-year performance period, and will be used to calculate the number of shares that will be issuable when the award vests, which may range from zero to 200 percent of the target amount. At the end of the three-year performance period, the number of shares that are earned and vest will depend on the degree of achievement against the pre-established performance goal. PSUs that have been earned over the performance period will be paid out in common stock at the end of the performance period, subject generally to the executive’s continued employment and will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares actually earned and vested. As the performance metric is tied to year-over-year growth and actual results for the metric will not be determined until the end of each respective fiscal year, the Company is unable to determine the annual target for the second and third years of the performance period for this award at this time. Accordingly, an aggregate of 46,756 PSUs granted on March 10, 2015 are not included in the table above. The grant date fair value per share of the PSUs for which terms have been established was $94.57.

During the three months ended March 31, 2015, the Company recorded $0.1 million in stock-based compensation expense for equity awards in which the performance goals have been established and are probable of being achieved. The remaining unrecognized compensation expense related to these awards at March 31, 2015 was $1.7 million based on the Company’s current assessment of probability of achieving the performance goals. The weighted-average period over which the cost will be recognized is one year.

12.    Earnings Per Share

Basic net income per common share represents net income attributable to American Tower Corporation common stockholders divided by the weighted average number of common shares outstanding during the period. Diluted net income per common share represents net income attributable to American Tower Corporation common stockholders divided by the weighted average number of common shares outstanding during the period and any dilutive common share equivalents, including shares issuable (i) upon the vesting of restricted stock awards, (ii) upon exercise of stock options and (iii) upon conversion of the Company’s Mandatory Convertible Preferred Stock. Dilutive common share equivalents also include the dilutive impact of the ALLTEL transaction (see note 13).

The Company uses the treasury stock method to calculate the effect of its outstanding restricted stock awards and stock options and uses the if-converted method to calculate the effect of its outstanding Mandatory Convertible Preferred Stock.

13.    Commitments and Contingencies

Litigation

The Company periodically becomes involved in various claims, lawsuits and proceedings that are incidental to its business. In the opinion of Company management, after consultation with counsel, there are no matters currently pending that would, in the event of an adverse outcome, materially impact the Company’s consolidated financial position, results of operations or liquidity.

Lease Obligations

Tenant Leases—As part of the Verizon Transaction, the Company entered into leases or subleases with Verizon with respect to 11,448 communications sites with an initial non-cancellable term of ten years. In addition, the Company assumed the rights to the tenant leases that were in place on such sites at the time of the transaction. The total estimated future minimum rental receipts under the non-cancellable Verizon leases and in-place third-party leases is approximately $3.0 billion and is expected to be recognized over an average period of approximately 10 years.

Lease Obligations—In connection with the Verizon Transaction, the Company assumed the interest in and obligations under certain ground leases. Many of the leases contain renewal options with specified increases in

20

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

lease payments upon exercise of the renewal option. Escalation clauses present in operating leases, excluding those tied to CPI or other inflation-based indices, are recognized on a straight-line basis over the non-cancellable term of the leases. Future minimum rental payments under non-cancellable operating leases include payments for certain renewal periods at the Company’s option because failure to renew could result in a loss of the applicable communications sites and related revenues from tenant leases, thereby making it reasonably assured that the Company will renew the leases. The Company’s future minimum rental payments under non-cancellable operating leases, including certain renewal periods related to the Verizon communications sites is approximately $2.2 billion and is expected to be recognized over an average period of approximately 17 years.

Commitments

Verizon Transaction—On March 27, 2015, the Company entered into an agreement with various operating entities of Verizon that provides for the lease, sublease or management of 11,285 wireless communications sites from Verizon commencing March 27, 2015. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 28 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the leased sites in tranches, subject to the applicable lease, sublease or management right upon its scheduled expiration. Each tower is assigned to an annual tranche, ranging from 2034 to 2047, which represents the outside expiration date for the sublease rights to the towers in each tranche. The purchase price for each tranche is a fixed amount stated in the sublease for such tranche plus the fair market value of certain alterations made to the related towers by Verizon. The aggregate purchase option price for the towers leased and subleased is approximately $5.0 billion. Verizon will occupy the sites as a tenant for an initial term of ten years with eight optional successive five-year terms; each such term shall be governed by standard master lease agreement terms established as a part of the transaction.

AT&T Transaction—The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. (“AT&T”), that currently provides for the lease or sublease of approximately 2,400 towers from AT&T with the lease commencing between December 2000 and August 2004. Substantially all of the towers are part of the Company’s securitization transaction completed in March 2013. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 27 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the sites subject to the applicable lease or sublease upon its expiration. Each tower is assigned to an annual tranche, ranging from 2013 to 2032, which represents the outside expiration date for the sublease rights to that tower. The purchase price for each site is a fixed amount stated in the sublease for that site plus the fair market value of certain alterations made to the related tower by AT&T. As of March 31, 2015, the Company has purchased an aggregate of 31 of the subleased towers upon expiration of the applicable agreement. The aggregate purchase option price for the remaining towers leased and subleased is approximately $659.4 million and will accrete at a rate of 10% per annum through the applicable expiration of the lease or sublease of a site. For all such sites purchased by the Company prior to June 30, 2020, AT&T will continue to lease the reserved space at the then-current monthly fee which shall escalate in accordance with the standard master lease agreement for the remainder of AT&T’s tenancy. Thereafter, AT&T shall have the right to renew such lease for up to four successive five-year terms. For all such sites purchased by the Company subsequent to June 30, 2020, AT&T has the right to continue to lease the reserved space for successive one-year terms at a rent equal to the lesser of the agreed upon market rate and the then-current monthly fee, which is subject to an annual increase based on changes in the Consumer Price Index.

ALLTEL Transaction—In December 2000, the Company entered into an agreement with ALLTEL, a predecessor entity to Verizon Wireless, to acquire towers through a 15-year sublease agreement. Pursuant to the agreement, as amended, with Verizon Wireless, the Company acquired rights to approximately 1,800 towers in tranches between April 2001 and March 2002. The Company has the option to purchase each tower at the

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

expiration of the applicable sublease, which will occur in tranches between April 2016 and March 2017 based on the original closing date for such tranche of towers. The purchase price per tower as of the original closing date was $27,500 and will accrete at a rate of 3% per annum through the expiration of the applicable sublease. The aggregate purchase option price for the subleased towers is approximately $73.7 million as of March 31, 2015. At Verizon Wireless’s option, at the expiration of the sublease, the purchase price would be payable in cash or with 769 shares of the Company’s common stock per tower, which would be valued at approximately $128.2 million in the aggregate based on the closing price at March 31, 2015.

Other Contingencies—The Company is subject to income tax and other taxes in the geographic areas where it operates, and periodically receives notifications of audits, assessments or other actions by taxing authorities. The Company evaluates the circumstances of each notification based on the information available and records a liability for any potential outcome that is probable or more likely than not unfavorable if the liability is also reasonably estimable. On January 21, 2014, the Company received an income tax assessment in the amount of 22.6 billion Indian Rupees (approximately $369.0 million on the date of assessment), asserting tax liabilities arising out of a transfer pricing review of transactions by Essar Telecom Infrastructure Private Limited (“ETIPL”), and more specifically involving the issuance of share capital and the determination by the tax authority that an income tax obligation arose as a result of such issuance. The assessment was made with respect to transactions that took place in the tax year commencing in 2008, prior to the Company’s acquisition of ETIPL. Under the Company’s definitive acquisition agreement of ETIPL, the seller is obligated to indemnify and defend the Company with respect to any tax-related liability that may arise from activities prior to March 31, 2010. The Company challenged the assessment before India’s Income Tax Appellate Tribunal, which issued a decision in the Company’s favor on April 15, 2015, finding, consistent with precedent from the Bombay High Court, that no income tax obligation arose as a result of the issuance of share capital. The tax authority has the right to appeal this decision in accordance with applicable Indian law.

14.    Acquisitions and Other Transactions

The estimates of the fair value of the assets or rights acquired and liabilities assumed at the date of the applicable acquisition are subject to adjustment during the measurement period (up to one year from the particular acquisition date). The primary areas of the accounting for the acquisitions that are not yet finalized relate to the fair value of certain tangible and intangible assets acquired and liabilities assumed, including contingent consideration, and residual goodwill and any related tax impact. The fair value of these net assets acquired are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. While the Company believes that such preliminary estimates provide a reasonable basis for estimating the fair value of assets acquired and liabilities assumed, it will evaluate any necessary information prior to finalization of the fair value. During the measurement period, the Company will adjust assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the revised estimated values of those assets or liabilities as of that date. The effect of measurement period adjustments to the estimated fair value is reflected as if the adjustments had been completed on the acquisition date. The impact of all changes that do not qualify as measurement period adjustments are included in current period earnings. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the condensed consolidated financial statements could be subject to a possible impairment of the intangible assets or goodwill, or require acceleration of the amortization expense of intangible assets in subsequent periods. During the three months ended March 31, 2015, the Company made certain measurement period adjustments related to several acquisitions consummated in 2014 and therefore retrospectively adjusted the fair value of the assets acquired and liabilities assumed in the condensed consolidated balance sheet as of December 31, 2014.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Impact of current year acquisitions—The Company typically acquires communications sites from wireless carriers or other tower operators and subsequently integrates those sites into its existing portfolio of communications sites. The financial results of the Company’s acquisitions have been included in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2015 from the date of the respective acquisition. The date of acquisition, and by extension the point at which the Company begins to recognize the results of an acquisition, may be dependent upon, among other things, the receipt of contractual consents, the commencement and extent of leasing arrangements and the timing of the transfer of title or rights to the assets, which may be accomplished in phases. Sites acquired from communications service providers may never have been operated as a business and may have been utilized solely by the seller as a component of its network infrastructure. An acquisition, depending on its size and nature, may or may not involve the transfer of business operations or employees.

The estimated aggregate impact of the 2015 acquisitions and the Verizon Transaction on the Company’s revenues and gross margin for the three months ended March 31, 2015 was approximately $4.5 million and $2.1 million, respectively. The revenues and gross margin amounts also reflect incremental revenues from the addition of new tenants to such sites subsequent to the transaction date. Incremental amounts of segment selling, general, administrative and development expense have not been reflected, as the amounts attributable to transactions are not comparable.

For those acquisitions accounted for as business combinations, the Company recognizes acquisition and merger related costs in the period in which they are incurred and services are received. Acquisition and merger related costs may include finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees, fair value adjustments to contingent consideration and general administrative costs directly related to the transaction, and are included in Other operating expenses in the condensed consolidated statements of operations. During the three months ended March 31, 2015 and 2014, the Company recognized acquisition and merger related expenses of $3.0 million and $9.8 million, respectively. In addition, during the three months ended March 31, 2015 and 2014, the Company recorded $1.8 million and $2.5 million, respectively, of integration costs related to recently closed acquisitions.

Verizon Transaction

On March 27, 2015, the Company completed its acquisition of the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon for approximately $5.053 billion in cash pursuant to the Master Agreement entered into on February 5, 2015 (the “Master Agreement”) and the related Master Prepaid Lease, Management Agreement, Sale Site Master Lease Agreement and MPL Site Master Lease Agreement.

The Company, through its wholly-owned subsidiary, leased or subleased from certain Verizon subsidiaries 11,285 communications sites, including the interest in the land, the tower and certain related improvements and tower related assets pursuant to the Master Prepaid Lease. Under the Master Prepaid Lease, the Company has the exclusive right to lease and operate the Verizon communications sites for a weighted average term of approximately 28 years and the Company will have the option to purchase the communications sites at the end of the respective lease or sublease terms at a fixed amount stated in the sublease for such tranche plus the fair market value of certain alterations made to the related towers. The Company accounted for the payment with respect to the leased sites as a capital lease and the respective lease and non-lease elements related to tower assets and intangible assets, as described below. The total consideration allocated to this element of the overall transaction was $4.964 billion, which included approximately $9.9 million of transaction costs.

23

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

In addition, the Company, through its wholly-owned subsidiary, acquired 163 additional communications sites. The Company accounted for these sites as a business combination and the purchase price of $99.0 million is reflected below in “2015 Acquisitions.”

Upon closing, the Company agreed to lease, sublease or otherwise make available collocation space at each of the communications sites to Verizon for an initial non-cancellable term of ten years, subject to automatic extension for eight additional five-year renewal terms. The initial collocation rent is $1,900 per month for each communications site, with annual rent increases of 2%.

The Company funded the Verizon Transaction with (i) proceeds from its concurrent registered public offerings of its common stock and Series B Preferred Stock (see note 11), (ii) borrowings under the Company’s revolving credit facilities and (iii) cash on hand.

The Company included the Verizon Transaction in the unaudited pro forma financial results included herein as if the capital lease began on January 1, 2014. Management relied on various estimates and assumptions due to the fact that Verizon did not operate the sites as a business and the sites were utilized primarily by Verizon as a component of its network infrastructure.

The following table summarizes the allocation of consideration transferred for the 11,285 communications sites under the Master Prepaid Lease (in thousands). Balances are reflected in the accompanying condensed consolidated balance sheets as of March 31, 2015 and represent the asset balances of the capital lease.

Pro Forma Consolidated Results

The following table presents the unaudited pro forma financial results as if the 2015 acquisitions, as well as the Verizon Transaction described above, had occurred on January 1, 2014 and the 2014 acquisitions had occurred on January 1, 2013 (in thousands, except per share data). Management relied on various estimates and assumptions due to the fact that some of the transactions never operated as a business and were utilized solely by the seller as a component of their network infrastructure. As a result, historical operating results may not be available. The pro forma results do not include any anticipated cost synergies, costs or other integration impacts. Accordingly, such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the transactions been completed on the dates indicated, nor are they indicative of the future operating results of the Company.

15.    Business Segments

The Company operates in three business segments, (i) domestic rental and management, (ii) international rental and management and (iii) network development services. The Company’s primary business is leasing space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. This business is referred to as the Company’s rental and management operations and is comprised of domestic and international segments, which, as of March 31, 2015, consisted of the following:

• Domestic: rental and management operations in the United States; and

• International: rental and management operations in Brazil, Chile, Colombia, Costa Rica, Germany, Ghana, India, Mexico, Peru, South Africa and Uganda. In November 2014, the Company signed an agreement to acquire communications sites in Nigeria.

The Company has applied the aggregation criteria to operations within the international rental and management operating segments on a basis consistent with management’s review of information and performance evaluation.

The Company’s network development services segment offers tower-related services in the United States, including site acquisition, zoning and permitting services and structural analysis services, which primarily support its site leasing business and the addition of new tenants and equipment on its sites. The network development services segment is a strategic business unit that offers different services from the rental and management operating segments and requires different resources, skill sets and marketing strategies.

The accounting policies applied in compiling segment information below are similar to those described in note 1 to the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2014. Among other factors, in evaluating financial performance in each business segment, management uses segment gross margin and segment operating profit. The Company defines segment gross margin as segment revenue less segment operating expenses excluding stock-based compensation expense recorded in costs of operations; Depreciation, amortization and accretion; Selling, general, administrative and development expense; and Other operating expenses. The Company defines segment operating profit as segment gross margin less Selling, general, administrative and development expense attributable to the segment, excluding stock-based compensation expense and corporate expenses. For reporting purposes, the international

rental and management segment gross margin and segment operating profit also include Interest income, TV Azteca, net. These measures of segment gross margin and segment operating profit are also before Interest income, Interest expense, Gain (loss) on retirement of long-term obligations, Other income (expense), Net income (loss) attributable to noncontrolling interest, Income (loss) on equity method investments and Income tax benefit (provision). The categories of expenses indicated above, such as depreciation, have been excluded from segment operating performance as they are not considered in the review of information or the evaluation of results by management. There are no significant revenues resulting from transactions between the Company’s operating segments. All intercompany transactions are eliminated to reconcile segment results and assets to the condensed consolidated statements of operations and condensed consolidated balance sheets.

Summarized financial information concerning the Company’s reportable segments for the three months ended March 31, 2015 and 2014 is shown in the following tables. The “Other” column (i) represents amounts excluded from specific segments, such as business development operations, stock-based compensation expense and corporate expenses included in Selling, general, administrative and development expense; Other operating expenses; Interest income; Interest expense; Gain (loss) on retirement of long-term obligations; and Other income (expense), and (ii) reconciles segment operating profit to Income from continuing operations before income taxes, as the amounts are not utilized in assessing each segment’s performance.

The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates and such differences could be material to the financial statements. This discussion should be read in conjunction with our condensed consolidated financial statements herein and the accompanying notes thereto, information set forth under the caption “Critical Accounting Policies and Estimates” of our Annual Report on Form 10-K for the year ended December 31, 2014, and in particular, the information set forth therein under Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Overview

We are one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. Our primary business is the leasing of space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data and data providers, government agencies and municipalities and tenants in a number of other industries. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners under various contractual arrangements. We also hold property interests that we lease to communications service providers and third-party tower operators. We refer to this business as our rental and management operations, which accounted for approximately 98% of our total revenues for the three months ended March 31, 2015 and includes our domestic rental and management segment and our international rental and management segment. Through our network development services, we offer tower-related services domestically, including site acquisition, zoning and permitting services and structural analysis services, which primarily support our site leasing business and the addition of new tenants and equipment on our sites, including in connection with provider network upgrades. We operate as a real estate investment trust for U.S. federal income tax purposes (“REIT”).

On March 27, 2015, we significantly expanded our domestic portfolio by obtaining the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon Communications Inc. (“Verizon”) in the United States (the “Verizon Transaction”). As a result, our communications real estate portfolio of 87,640 sites as of March 31, 2015, included 40,048 communications towers domestically, 47,149 communications towers internationally and 443 distributed antenna system (“DAS”) networks, which provide seamless coverage solutions in certain in-building and outdoor wireless environments. Our portfolio primarily consists of towers that we own and towers that we operate pursuant to long-term lease arrangements.

The following table details the number of communications sites, excluding managed sites, we owned or operated as of March 31, 2015:

Country	Number of Owned  Sites		Number of Operated Sites  (1)

Uganda		1,326		—

(1) All of the communications sites we operate are held pursuant to long-term capital leases, including those subject to purchase options.

Our continuing operations are reported in three segments: domestic rental and management, international rental and management and network development services. In evaluating operating performance in each business segment, management uses, among other factors, segment gross margin and segment operating profit. We define segment gross margin as segment revenue less segment operating expenses, excluding stock-based compensation expense recorded in costs of operations; Depreciation, amortization and accretion; Selling, general, administrative and development expense; and Other operating expense. We define segment operating profit as segment gross margin less Selling, general, administrative and development expense attributable to the segment, excluding stock-based compensation expense and corporate expenses. Segment gross margin and segment operating profit for the international rental and management segment also include Interest income, TV Azteca, net (see note 15 to our condensed consolidated financial statements included herein). These measures of segment gross margin and segment operating profit are also before Interest income, Interest expense, Gain (loss) on retirement of long-term obligations, Other income (expense), Net income (loss) attributable to noncontrolling interest, Income (loss) on equity method investments and Income tax benefit (provision).

In the section that follows, we provide information regarding management’s expectations of long-term drivers of demand for our communications sites, as well as our current results of operations, financial position and sources and uses of liquidity. In addition, we highlight key trends, which management believes provide valuable insight into our operating and financial resource allocation decisions.

Revenue Growth. Due to our diversified communications site portfolio, our tenant lease rates vary considerably depending upon numerous factors, including, but not limited to, amount and type of tenant equipment on the tower, ground space required by the tenant, remaining tower capacity and tower location. We measure the remaining tower capacity by assessing several factors, including tower height, tower type, environmental conditions, existing equipment on the tower and zoning and permitting regulations in effect in the jurisdiction where the tower is located. In many instances, tower capacity can be increased through tower augmentation.

The primary factors affecting the revenue growth of our domestic and international rental and management segments are:

• Recurring organic revenue from tenant leases attributable to sites that existed in our portfolio as of the beginning of the prior year period (“legacy sites”);

33

• Contractual rent escalations on existing tenant leases, net of cancellations;

• New revenue attributable to leasing additional space on our legacy sites; and

• New revenue attributable to sites acquired or constructed since the beginning of the prior year period (“new sites”).

The majority of our tenant leases with wireless carriers have an initial non-cancellable term of ten years, with multiple renewal terms. Accordingly, nearly all of the revenue generated by our rental and management operations during the three months ended March 31, 2015 was recurring revenue that we should continue to receive in future periods. Based upon foreign currency exchange rates and the tenant leases in place as of March 31, 2015, we expect to generate approximately $29 billion of non-cancellable tenant lease revenue over future periods, absent the impact of straight-line lease accounting. This expected revenue includes the impact of the tenant leases we entered into or assumed in connection with the Verizon Transaction. Most of our tenant leases have provisions that periodically increase the rent due under the lease, typically annually based on a fixed escalation (approximately 3% in the United States) or an inflationary index in our international markets, or a combination of both. In addition, certain of our tenant leases provide for additional revenue to cover costs, such as ground rent or power and fuel costs.

Revenue lost from either cancellations of leases at the end of their terms or rent negotiations historically has not had a material adverse effect on the revenues generated by our rental and management operations. During the three months ended March 31, 2015, loss of revenue from tenant lease cancellations or renegotiations represented approximately 2% of our rental and management operations revenues.

Demand Drivers. We continue to believe that our site leasing revenue is likely to increase due to the growing use of wireless communications services and our ability to meet the corresponding incremental demand for our wireless real estate. By adding new tenants and new equipment for existing tenants on our sites, we are able to increase these sites’ utilization and profitability. We believe the majority of our site leasing activity will continue to come from wireless service providers. Our legacy site portfolio and our established tenant base provide us with new business opportunities, which have historically resulted in consistent and predictable organic revenue growth as wireless carriers seek to increase the coverage and capacity of their existing networks, while also deploying next generation wireless technologies. In addition, we intend to continue to supplement the organic growth on our legacy sites by selectively developing or acquiring new sites in our existing and new markets where we can achieve our risk adjusted return on investment objectives. In a majority of our international markets, revenue also includes the reimbursement of direct costs such as ground rent or power and fuel costs.

Based on industry research and projections, we expect the following key industry trends will result in incremental revenue opportunities for us:

• Subscribers’ use of wireless data continues to grow rapidly given increasing smartphone and other advanced device penetration, the proliferation of bandwidth-intensive applications on these devices and the continuing evolution of the mobile ecosystem. We believe carriers will be compelled to deploy additional equipment on existing networks while also rolling out more advanced wireless networks to address coverage and capacity needs resulting from this increasing wireless data usage.

• The deployment of advanced wireless technology across existing wireless networks will provide higher speed data services and enable fixed broadband substitution. As a result, we expect our tenants to continue deploying additional equipment across their existing networks.

• Wireless service providers compete based on the quality of their existing wireless networks, which is driven by capacity and coverage. To maintain or improve their network performance as overall network usage increases, our tenants continue deploying additional equipment across their existing sites while also adding new cell sites. We anticipate increasing network densification over the next several years, as existing network infrastructure is anticipated to be insufficient to account for rapidly increasing levels of wireless data usage.

34

• Wireless service providers are also investing in reinforcing their networks through incremental backhaul and the utilization of on-site generators, which typically results in additional equipment or space leased at the tower site and incremental revenue.

• Wireless service providers continue to acquire additional spectrum, and as a result are expected to add additional sites and equipment to their network as they seek to optimize their network configuration.

As part of our international expansion initiatives, we have targeted markets in various stages of network development to diversify our international exposure and position us to benefit from a number of different wireless technology deployments over the long term. In addition, we have focused on building relationships with large multinational carriers such as Bharti Airtel Limited, MTN Group Limited, Telefónica S.A. and Vodafone Group PLC. We believe that consistent carrier investments in their networks across our international markets position us to generate meaningful organic revenue growth going forward.

In emerging markets, such as Ghana, India and Uganda, wireless networks tend to be significantly less advanced than those in the United States, and initial voice networks continue to be deployed in underdeveloped areas. A majority of consumers in these markets still utilize basic wireless services, predominantly on feature phones, and advanced device penetration remains low. In more developed urban locations within these markets, early-stage data network deployments are underway. Carriers are focused on completing voice network build-outs while also investing in initial data networks as wireless data usage and smartphone penetration within their customer bases begin to accelerate.

In markets with rapidly evolving network technology, such as South Africa and most of the countries in Latin America where we do business, initial voice networks, for the most part, have already been built out, and carriers are focused on third generation (3G) network build outs, with select investments in fourth generation (4G) technology. Consumers in these regions are increasingly adopting smartphones and other advanced devices, and as a result, the usage of bandwidth-intensive mobile applications is growing materially. Recent spectrum auctions in these rapidly evolving markets have allowed incumbent carriers to accelerate their data network deployments and have also enabled new entrants to begin initial investments in data networks. Smartphone penetration and wireless data usage in these markets are growing rapidly, which mandates that carriers continue to invest in their networks in order to maintain and augment their quality of service.

Finally, in markets with more mature network technology, such as Germany, carriers are focused on deploying 4G data networks to account for rapidly increasing wireless data usage amongst their customer base. With higher smartphone and advanced device penetration and significantly higher per capita data usage, carrier investment in networks is focused on 4G coverage and capacity.

We believe that the network technology migration we have seen in the United States, which has led to significantly denser networks and meaningful new business commencements for us over a number of years, will ultimately be replicated in our less advanced international markets. As a result, we expect to be able to leverage our extensive international portfolio of over 47,000 communications sites and the relationships we have built with our carrier customers to drive sustainable, long-term growth.

Rental and Management Operations Expenses. Direct operating expenses incurred by our domestic and international rental and management segments include direct site level expenses and consist primarily of ground rent and power and fuel costs, some of which may be passed through to our tenants, as well as property taxes, repairs and maintenance. These segment direct operating expenses exclude all segment and corporate selling, general, administrative and development expenses, which are aggregated into one line item entitled Selling, general, administrative and development expense in our condensed consolidated statements of operations. In general, our domestic and international rental and management segments’ selling, general, administrative and development expenses do not significantly increase as a result of adding incremental tenants to our legacy sites and typically increase only modestly year-over-year. As a result, leasing additional space to new tenants on our legacy sites provides significant incremental cash flow. We may, however, incur additional segment selling,

35

general, administrative and development expenses as we increase our presence in geographic areas where we have launched operations or are focused on expanding our portfolio. Our profit margin growth is therefore positively impacted by the addition of new tenants to our legacy sites and can be temporarily diluted by our development activities.

Network Development Services Segment Revenue Growth. As we continue to focus on growing our rental and management operations, we anticipate that our network development services revenue will continue to represent a small percentage of our total revenues.

Non-GAAP Financial Measures

Included in our analysis of our results of operations are discussions regarding earnings before interest, taxes, depreciation, amortization and accretion, as adjusted (“Adjusted EBITDA”), Funds From Operations, as defined by the National Association of Real Estate Investment Trusts (“NAREIT FFO”) and Adjusted Funds From Operations (“AFFO”).

We define Adjusted EBITDA as Net income before Income (loss) on discontinued operations, net; Income (loss) on equity method investments; Income tax benefit (provision); Other income (expense); Gain (loss) on retirement of long-term obligations; Interest expense; Interest income; Other operating income (expense); Depreciation, amortization and accretion; and stock-based compensation expense.

NAREIT FFO is defined as net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges, real estate related depreciation, amortization and accretion and dividends on preferred stock, and including adjustments for (i) unconsolidated affiliates and (ii) noncontrolling interest.

We define AFFO as NAREIT FFO before (i) straight-line revenue and expense; (ii) stock-based compensation expense; (iii) the non-cash portion of our tax provision; (iv) non-real estate related depreciation, amortization and accretion; (v) amortization of deferred financing costs, capitalized interest, debt discounts and premiums and long-term deferred interest charges; (vi) other income (expense); (vii) gain (loss) on retirement of long-term obligations; (viii) other operating income (expense); and adjustments for (ix) unconsolidated affiliates and (x) noncontrolling interest, less cash payments related to capital improvements and cash payments related to corporate capital expenditures.

Adjusted EBITDA, NAREIT FFO and AFFO are not intended to replace net income or any other performance measures determined in accordance with GAAP. Neither NAREIT FFO nor AFFO represent cash flows from operating activities in accordance with GAAP and, therefore, these measures should not be considered indicative of cash flows from operating activities as a measure of liquidity or of funds available to fund our cash needs, including our ability to make cash distributions.

Our measurement of Adjusted EBITDA, NAREIT FFO and AFFO may not, however, be fully comparable to similarly titled measures used by other companies. Reconciliations of Adjusted EBITDA, NAREIT FFO and AFFO to net income, the most directly comparable GAAP measure, have been included below.

For more information regarding these measures, see “Non-GAAP Financial Measures” under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2014.

Results of Operations

Three Months Ended March 31, 2015 and 2014 (in thousands, except percentages)

Revenue

	Three Months Ended March 31,				Amount of Increase (Decrease)			Percent Increase (Decrease)
	2015		2014
Rental and management
Domestic	$	717,880	$	635,779	$	82,101			13	%
International		344,300		324,341		19,959			6
Total rental and management		1,062,180		960,120		102,060			11
Network development services		17,010		23,969		(6,959	)		(29	)
Total revenues	$	1,079,190	$	984,089	$	95,101			10	%

The increase in total revenues was primarily attributable to an increase in both of our rental and management segments, including organic revenue growth attributable to our legacy sites, and revenue growth attributable to the approximately 20,586 new sites that we have constructed or acquired since January 1, 2014. Approximately $4.2 million of the increase was attributable to revenues generated by assets included in the Verizon Transaction.

Domestic rental and management segment revenue growth for the three months ended March 31, 2015 was comprised of:

• Revenue growth from legacy sites of approximately 9%, which included approximately 6% primarily generated by new tenant leases and amendments to existing tenant leases, approximately 1% attributable to contractual rent escalations, net of tenant lease cancellations and less than 2% from accelerated revenue recognition under a multi-year equipment agreement with a major tenant; and

• Revenue growth of approximately 4% from 12,399 new sites, as well as land interests under third-party sites, constructed, leased or acquired since January 1, 2014.

International rental and management segment revenue growth for the three months ended March 31, 2015 was comprised of:

• Revenue growth of approximately 12% from 8,187 new sites constructed or acquired since January 1, 2014;

• Revenue growth from legacy sites of approximately 10%, which included approximately 7% due to incremental revenue primarily generated from new tenant leases and amendments to existing tenant leases and approximately 3% attributable to contractual rent escalations, net of tenant lease cancellations; and

• A decrease of approximately 16% attributable to the negative impact from foreign currency translation, which included, among others, the negative impact of approximately 6% related to fluctuations in Brazilian Reais (“BRL”) and 3% related to fluctuations in both Mexican Peso (“MXN”) and Ghanaian Cedi (“GHS”).

The decrease in network development services segment revenue during the three months ended March 31, 2015 was primarily due to a decrease in structural engineering services.

Gross Margin

	Three Months Ended March 31,				Amount  of Increase (Decrease)			Percent Increase (Decrease)
	2015		2014
Rental and management
Domestic	$	584,848	$	514,270	$	70,578			14	%
International		221,103		197,982		23,121			12

Network development services		11,766		14,167		(2,401	)		(17	)%

Domestic rental and management segment gross margin growth for the three months ended March 31, 2015 was comprised of:

• Gross margin growth from legacy sites of approximately 10%, primarily associated with the increase in revenue, as described above;

• Gross margin growth from new sites of over 3%, primarily associated with the increase in revenue, as described above; and

• An increase of approximately 1% from the impact of straight-line lease accounting.

International rental and management segment gross margin growth for the three months ended March 31, 2015 was comprised of:

• Gross margin growth from legacy sites of approximately 15%, primarily associated with the increase in revenue, as described above;

• Gross margin growth from new sites of approximately 13%, primarily associated with the increase in revenue, as described above;

• Gross margin growth of approximately 1% from the impact of straight-line lease accounting; and

• A decrease of approximately 17% attributable to the negative impact from foreign currency translation, which includes, among others, the negative impact of approximately 6% related to fluctuations in BRL, approximately 4% related to fluctuations in MXN and approximately 3% related to fluctuations in GHS.

The decrease in network development services segment gross margin for the three months ended March 31, 2015 was primarily due to the decrease in revenue as described above.

Selling, General, Administrative and Development Expense

	Three Months Ended March 31,				Amount  of Increase (Decrease)			Percent Increase (Decrease)
	2015		2014
Rental and management
Domestic	$	26,822	$	27,409	$	(587	)		(2	)%
International		34,611		29,216		5,395			18
Total rental and management		61,433		56,625		4,808			8

Total selling, general, administrative and development expense	$	123,290	$	110,029	$	13,261			12	%

38

The decrease in domestic rental and management segment selling, general, administrative and development expense (“SG&A”) was primarily driven by a decrease in project cancellation costs compared to the three months ended March 31, 2014.

The increase in international rental and management segment SG&A for the three months ended March 31, 2015 was primarily due to the impact of increased personnel costs to support our business, including additional costs associated with acquisitions and an increase in bad debt expense, as SG&A for the three months ended March 31, 2014 included a reversal of bad debt expense for amounts previously reserved. The increase in international SG&A was partially offset by decreases attributable to impacts of foreign currency fluctuations.

The increase in network development services segment SG&A for the three months ended March 31, 2015 was primarily due to higher personnel costs.

The increase in other SG&A for the three months ended March 31, 2015 was due to an increase of $5.2 million related to stock-based compensation expense and an increase of $2.3 million in corporate SG&A. The increase in corporate SG&A was primarily related to personnel costs to support our business.

Operating Profit 

	Three Months Ended March 31,				Amount  of Increase (Decrease)			Percent Increase (Decrease)
	2015		2014
Rental and management
Domestic	$	558,026	$	486,861	$	71,165			15	%
International		186,492		168,766		17,726			11
Total rental and management		744,518		655,627		88,891			14
Network development services		8,330		11,637		(3,307	)		(28	)%

Domestic rental and management segment operating profit growth for the three months ended March 31, 2015 was primarily attributable to an increase in our domestic rental and management segment gross margin (14%), as well as a decrease in our domestic rental and management SG&A (2%).

International rental and management segment operating profit growth for the three months ended March 31, 2015 was primarily attributable to an increase in our international rental and management segment gross margin (12%) and was partially offset by an increase in our international rental and management segment SG&A (18%).

The decrease in network development services segment operating profit for the three months ended March 31, 2015 was primarily attributable to the decrease in network development services segment gross margin (17%), as well as an increase in our network development services segment SG&A (36%).

Depreciation, Amortization and Accretion

	Three Months Ended March 31,				Amount  of Increase (Decrease)		Percent Increase (Decrease)
	2015		2014
Depreciation, amortization and accretion	$	263,520	$	245,763	$	17,757		7	%

The increase in depreciation, amortization and accretion expense for the three months ended March 31, 2015 was primarily attributable to the depreciation, amortization and accretion expense associated with the acquisition or construction of approximately 20,586 sites since January 1, 2014, which resulted in an increase in property and equipment and intangible assets subject to amortization.

39

Other Operating Expenses

	Three Months Ended March 31,				Amount  of Increase (Decrease)			Percent Increase (Decrease)
	2015		2014
Other operating expenses	$	7,774	$	13,891	$	(6,117	)		(44	)%

The decrease in other operating expenses for the three months ended March 31, 2015 was primarily attributable to a decrease of $7.5 million in integration, acquisition and merger related costs and was partially offset by an increase of $1.4 million from net losses on sales or disposals of long-lived assets.

Interest Expense

	Three Months Ended March 31,				Amount  of Increase (Decrease)		Percent Increase (Decrease)
	2015		2014
Interest expense	$	147,934	$	143,307	$	4,627		3	%

The increase in interest expense for the three months ended March 31, 2015 was primarily attributable to the increase in our annualized weighted average cost of borrowing from 4.01% to 4.08%, as our average debt outstanding remained essentially constant. The weighted average contractual interest rate was 3.66% at March 31, 2015.

Loss on Retirement of Long-Term Obligations

	Three Months Ended March 31,				Amount  of Increase (Decrease)		Percent Increase (Decrease)
	2015		2014
Loss on retirement of long-term obligations	$	3,725	$	238	$	3,487		1,465	%

During the three months ended March 31, 2015, we redeemed all of the outstanding 4.625% senior notes due 2015 (the “4.625% Notes”) for an aggregate redemption price of approximately $613.6 million, including approximately $10.0 million in accrued and unpaid interest. As a result, we recorded a loss on retirement of long-term obligations of $3.7 million, which included prepayment consideration and the remaining portion of the unamortized discount and deferred financing costs.

Other Expense

	Three Months Ended March 31,				Amount  of Increase (Decrease)		Percent Increase (Decrease)
	2015		2014
Other expense	$	54,503	$	3,743	$	50,760		1,356	%

During the three months ended March 31, 2015, other expense reflected $55.5 million of unrealized foreign currency losses, as compared to $2.0 million of unrealized foreign currency losses during the three months ended March 31, 2014. We record unrealized foreign currency gains or losses as a result of fluctuations in the foreign currency exchange rates primarily associated with our intercompany notes and similar unaffiliated balances denominated in a currency other than the subsidiaries’ functional currencies. During the three months ended March 31, 2015, we recorded unrealized foreign currency losses of $326.9 million, of which $271.4 million was recorded in accumulated other comprehensive income (loss) (“AOCI”) and $55.5 million was recorded in Other expense.

Income Tax Provision

	Three Months Ended March 31,						Amount  of Increase (Decrease)		Percent Increase (Decrease)
	2015			2014
Income tax provision	$	23,872		$	17,649		$	6,223		35	%
Effective tax rate		10.9	%		8.4	%

The increase in the effective tax rate (“ETR”) during the three months ended March 31, 2015 was primarily attributable to the impact of foreign currency translation.

As a REIT, we may deduct earnings distributed to stockholders against the income generated in our qualified REIT subsidiaries or other disregarded entities of a REIT (collectively, “QRSs”). In addition, we are able to offset income in certain taxable REIT subsidiaries (“TRSs”) and our QRSs by utilizing our net operating losses (“NOLs”), subject to specified limitations.

The ETR on income from continuing operations for the three months ended March 31, 2015 and 2014 differs from the federal statutory rate primarily due to our qualification for taxation as a REIT and adjustments for foreign items.

Net Income/Adjusted EBITDA

	Three Months Ended March 31,						Amount  of Increase (Decrease)			Percent Increase (Decrease)
	2015			2014
Net income	$	195,492		$	193,313		$	2,179			1	%

Adjusted EBITDA	$	723,717		$	640,490		$	83,227			13	%

The increase in net income for the three months ended March 31, 2015 was primarily due to the increase in our operating profit, which was partially offset by increases in other expense, depreciation, amortization and accretion expense, income tax provision and other SG&A.

The increase in Adjusted EBITDA for the three months ended March 31, 2015 was primarily attributable to the increase in our gross margin and was partially offset by an increase in SG&A of $8.1 million, excluding the impact of stock-based compensation expense.

AFFO	$	513,647		$	439,318		$	74,329			17	%

(1) Primarily includes unrealized losses on foreign currency exchange rate fluctuations.

(2) Primarily includes acquisition related costs, integration costs, losses from sale of assets and impairment charges.

AFFO growth was primarily attributable to the increase in our operating profit and decreases in cash paid for taxes and capital improvement and corporate capital expenditures, partially offset by increases in cash paid for interest and dividends on preferred stock.

Liquidity and Capital Resources

The information in this section updates as of March 31, 2015 the “Liquidity and Capital Resources” section of our Annual Report on Form 10-K for the year ended December 31, 2014 and should be read in conjunction with that report.

Overview

As a holding company, our cash flows are derived primarily from the operations of, and distributions from, our operating subsidiaries or funds raised through borrowings under our credit facilities and debt or equity offerings. As of March 31, 2015, we had approximately $2.7 billion of total liquidity, comprised of approximately $0.3 billion in cash and cash equivalents and the ability to borrow up to $2.4 billion, net of outstanding letters of credit, under our multi-currency senior unsecured revolving credit facility entered into in June 2013, as amended (the “2013 Credit Facility”) and our senior unsecured revolving credit facility entered into in January 2012, as amended and restated in September 2014 (the “2014 Credit Facility”). In April 2015, we borrowed an additional $1.6 billion under the 2013 Credit Facility.

42

Summary cash flow information for the three months ended March 31, 2015 and 2014 is set forth below (in thousands).

	Three months ended March 31,
	2015			2014
Net cash provided by (used for):
Operating activities	$	509,930		$	476,582
Investing activities		(5,249,419	)		(291,056	)
Financing activities		4,760,127			(152,901	)
Net effect of changes in exchange rates on cash and cash equivalents		(10,730	)		7,238
Net increase in cash and cash equivalents	$	9,908		$	39,863

We use our cash flows to fund our operations and investments in our business, including tower maintenance and improvements, communications site construction and managed network installations and tower and land acquisitions. Additionally, we use our cash flows to make distributions, including distributions of our REIT taxable income to maintain our qualification for taxation as a REIT under the Internal Revenue Code of 1986, as amended. We may also repurchase our existing indebtedness from time to time. We typically fund our international expansion efforts primarily through a combination of cash on hand, intercompany debt and equity contributions.

As of March 31, 2015, we had total outstanding indebtedness of approximately $15.7 billion, with a current portion of $789.2 million. During the three months ended March 31, 2015, we generated sufficient cash flow from operations to fund our capital expenditures and debt service obligations, as well as our required REIT distributions. We believe the cash generated by operating activities during the year ending December 31, 2015, together with our increased borrowing capacity under our credit facilities, will be sufficient to fund our required distributions, capital expenditures, debt service obligations (interest and principal repayments) and signed acquisitions. As of March 31, 2015, we had approximately $201.9 million of cash and cash equivalents held by our foreign subsidiaries, of which $59.3 million was held by our joint ventures. Historically, it has not been our practice to repatriate cash from our foreign subsidiaries primarily due to our ongoing expansion efforts and related capital needs. However, in the event that we do repatriate any funds, we may be required to accrue and pay taxes.

Cash Flows from Operating Activities

The increase in cash provided by operating activities for the three months ended March 31, 2015 was primarily due to an increase in the operating profit of our rental and management segments, a decrease in restricted cash and a decrease in cash paid for taxes, partially offset by a decrease in cash provided by working capital and an increase in cash paid for interest. Working capital, as compared to the three months ended March 31, 2014, was impacted by a decrease in unearned revenue and an increase in prepaid assets, partially offset by a decrease in accounts receivable.

Cash Flows from Investing Activities

Our significant investing activities during the three months ended March 31, 2015 included the following:

• We spent $5.058 billion, including approximately $4.7 million of transaction costs, for the Verizon Transaction.

• We spent $159.2 million for purchases of property and equipment and construction activities, including (i) $71.0 million of capital expenditures for discretionary capital projects, such as completion of the construction of approximately 655 communications sites and the installation of approximately six shared generators domestically, (ii) $29.0 million spent to acquire land under our towers that was

43

subject to ground agreements (including leases), (iii) $19.1 million of capital expenditures related to capital improvements primarily attributable to our communications sites and corporate capital expenditures primarily attributable to information technology improvements, (iv) $35.1 million for the redevelopment of existing communications sites to accommodate new tenant equipment and (v) $5.0 million of capital expenditures related to start-up capital projects primarily attributable to acquisitions and new market launches and costs that are contemplated in the business cases for these investments.

We plan to continue to allocate our available capital, after satisfying our distribution requirements, among investment alternatives that meet our return on investment criteria. Accordingly, we expect to continue to deploy our capital through our annual capital expenditure program, including land purchases and new site construction, and through acquisitions. We expect that our 2015 total capital expenditures will be between $850 million and $950 million, including between (i) $105 million and $115 million for capital improvements and corporate capital expenditures, (ii) $85 million and $95 million for start-up capital projects, (iii) $155 million and $175 million for the redevelopment of existing communications sites, (iv) $170 million and $190 million for ground lease purchases and (v) $335 million and $375 million for other discretionary capital projects, including the construction of approximately 2,750 to 3,250 new communications sites.

Cash Flows from Financing Activities

For the three months ended March 31, 2015 and 2014, our significant financing transactions were as follows (in millions):

	Three months ended March 31,
	2015			2014
Proceeds from issuance of senior notes, net	$	—		$	769.6
Proceeds from issuance of common stock, net		2,440.4			—
Proceeds from issuance of preferred stock, net		1,338.0			—
Proceeds from borrowings on (repayment of) credit facilities, net		1,280.0			(798.0	)
Proceeds from term loan		500.0			—
Repayment of senior notes		(600.0	)		—

In addition to the transactions noted above, we have increased the availability under our credit facilities by an aggregate of $1.25 billion.

Common Stock Offering. On March 3, 2015, we completed a registered public offering of 23,500,000 shares of our common stock, par value $0.01 per share, at $97.00 per share. On March 5, 2015, we issued an additional 2,350,000 shares of common stock in connection with the underwriters’ exercise in full of their over-allotment option. Aggregate net proceeds were approximately $2.44 billion after deducting commissions and estimated expenses. We used the net proceeds from this offering to fund a portion of the Verizon Transaction.

Preferred Stock Offering. On March 3, 2015, we completed a registered public offering of 12,500,000 depositary shares, each representing a 1/10th interest in a share of our 5.50% Mandatory Convertible Preferred Stock, Series B, par value $0.01 per share (the “Series B Preferred Stock”), at $100.00 per depositary share. On March 5, 2015, we issued an additional 1,250,000 depositary shares in connection with the underwriters’ exercise in full of their over-allotment option. Aggregate net proceeds were approximately $1.34 billion after deducting commissions and estimated expenses. We used the net proceeds from this offering to fund a portion of the Verizon Transaction. 

Unless converted or redeemed earlier, each share of the Series B Preferred Stock will convert automatically on February 15, 2018, into between 8.5911 and 10.3093 shares of common stock, depending on the applicable market value of our common stock and subject to anti-dilution adjustments. Subject to certain restrictions, at any

44

time prior to February 15, 2018, holders of the Series B Preferred Stock may elect to convert all or a portion of their shares into common stock at the minimum conversion rate then in effect.

Dividends on shares of the Series B Preferred Stock are payable on a cumulative basis when, as and if declared by our Board of Directors (or an authorized committee thereof) at an annual rate of 5.50% on the liquidation preference of $1,000.00 per share (and, correspondingly, $100.00 per share with respect to the depositary shares) on February 15, May 15, August 15 and November 15 of each year, commencing on May 15, 2015 to, and including, February 15, 2018. We may pay dividends in cash or, subject to certain limitations, in shares of common stock or any combination of cash and shares of common stock. The terms of the Series B Preferred Stock provide that, unless full cumulative dividends have been paid or set aside for payment on all outstanding Series B Preferred Stock for all prior dividend periods, no dividends may be declared or paid on common stock.

2014 Credit Facility. During the three months ended March 31, 2015, we increased the maximum Revolving Loan Commitment (as defined in the loan agreement) under the 2014 Credit Facility to $2.5 billion. Effective February 20, 2015, we received incremental commitments for an additional $500.0 million. As a result, we currently have the ability to borrow up to $2.0 billion under the 2014 Credit Facility.

During the three months ended March 31, 2015, we borrowed an aggregate of $2.1 billion and repaid an aggregate of $1.3 billion of revolving indebtedness under the 2014 Credit Facility. We primarily used the borrowings to fund a portion of the Verizon Transaction. As of March 31, 2015, we had $1.98 billion outstanding under the 2014 Credit Facility and $7.5 million of undrawn letters of credit. We maintain the ability to draw down and repay amounts under the 2014 Credit Facility in the ordinary course.

The 2014 Credit Facility has a term of approximately five years, matures on January 31, 2020 and includes two optional renewal periods. The 2014 Credit Facility does not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium. The current margin over the London Interbank Offered Rate (“LIBOR”) that we incur on borrowings is 1.250%, and the current commitment fee on the undrawn portion of the 2014 Credit Facility is 0.150%.

2013 Credit Facility. During the three months ended March 31, 2015, we increased the maximum Revolving Loan Commitment (as defined in the loan agreement) under the 2013 Credit Facility to $3.5 billion. Effective February 20, 2015, we received incremental commitments for an additional $750.0 million. As a result, we currently have the ability to borrow up to $2.75 billion under the 2013 Credit Facility.

During the three months ended March 31, 2015, we borrowed an aggregate of $1.0 billion, which we primarily used to fund a portion of the Verizon Transaction, and repaid an aggregate of $615.0 million of revolving indebtedness under the 2013 Credit Facility. As of March 31, 2015, we had $400.0 million outstanding under the 2013 Credit Facility and $3.2 million of undrawn letters of credit. We maintain the ability to draw down and repay amounts under the 2013 Credit Facility in the ordinary course. In April 2015, we borrowed an additional $1.6 billion under the 2013 Credit Facility, primarily to fund an acquisition in Brazil and repay other indebtedness.

The 2013 Credit Facility has a term of five years, matures on June 28, 2018 and includes two optional one-year renewal periods. The 2013 Credit Facility does not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium. The current margin over LIBOR that we incur on borrowings is 1.250%, and the current commitment fee on the undrawn portion of the 2013 Credit Facility is 0.150%.

2013 Term Loan. In October 2013, we entered into an unsecured term loan (the “2013 Term Loan”). The 2013 Term Loan matures on January 3, 2019. The current interest rate under the 2013 Term Loan is LIBOR plus

45

1.250%. During the three months ended March 31, 2015, the maximum Incremental Term Loan Commitments (as defined in the agreement) was increased to $1.0 billion. Effective February 20, 2015, we received an additional $500.0 million under the 2013 Term Loan. As a result, as of March 31, 2015, we had $2.0 billion outstanding under the 2013 Term Loan.

Amendments to Bank Facilities. During the three months ended March 31, 2015, we entered into amendment agreements with respect to the 2014 Credit Facility, the 2013 Credit Facility and the 2013 Term Loan. After giving effect to these amendments, our permitted ratio of Total Debt to Adjusted EBITDA (as defined in the loan agreements for each of the facilities) is (i) 7.25 to 1.00 for the fiscal quarters ended March 31, 2015 and June 30, 2015, (ii) 7.00 to 1.00 for the fiscal quarters ended September 30, 2015 and December 31, 2015 and (iii) 6.00 to 1.00 thereafter.

Redemption of Senior Notes. On February 11, 2015, we redeemed all of the outstanding 4.625% Notes. In accordance with the redemption provisions in the indenture, the 4.625% Notes were redeemed at a price equal to 100.5898% of the principal amount, plus accrued interest up to, but excluding, February 11, 2015, for an aggregate redemption price of approximately $613.6 million, including approximately $10.0 million in accrued and unpaid interest. The redemption was funded with borrowings under the 2013 Credit Facility. Upon completion of this redemption, none of the 4.625% Notes remained outstanding.

On April 29, 2015, we redeemed all of the outstanding 7.000% senior notes due 2017 (the “7.000% Notes”), in accordance with the redemption provisions in the indenture, at a price equal to 114.0629% of the principal amount, plus accrued and unpaid interest up to, but excluding, April 29, 2015, for an aggregate redemption price of approximately $571.7 million, including approximately $1.4 million in accrued and unpaid interest. We expect to record a loss on retirement of long-term obligations of approximately $74.3 million. The redemption was funded with borrowings under our existing credit facilities and cash on hand. Upon completion of this redemption, none of the 7.000% Notes remained outstanding.

Stock Repurchase Program. In March 2011, our Board of Directors approved a stock repurchase program, pursuant to which we are authorized to purchase up to $1.5 billion of common stock (the “2011 Buyback”). As of March 31, 2015, we had $1.1 billion remaining under the 2011 Buyback. In September 2013, we temporarily suspended repurchases.

Sales of Equity Securities. We receive proceeds from sales of our equity securities pursuant to our employee stock purchase plan and upon exercise of stock options granted under our equity incentive plans. For the three months ended March 31, 2015, we received an aggregate of $5.1 million in proceeds upon exercises of stock options.

Distributions. As a REIT, we must annually distribute to our stockholders an amount equal to at least 90% of our REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). Generally, we have distributed, and expect to continue to distribute all or substantially all of our REIT taxable income after taking into consideration our utilization of NOLs. Since our conversion to a REIT in 2012, we have distributed an aggregate of approximately $1.5 billion to our common stockholders, primarily subject to taxation as ordinary income.

The amount, timing and frequency of future distributions will be at the sole discretion of our Board of Directors and will be declared based upon various factors, a number of which may be beyond our control, including our financial condition and operating cash flows, the amount required to maintain our qualification for taxation as a REIT and reduce any income and excise taxes that we otherwise would be required to pay, limitations on distributions in our existing and future debt and preferred equity instruments, our ability to utilize NOLs to offset our distribution requirements, limitations on our ability to fund distributions using cash generated through our TRSs and other factors that our Board of Directors may deem relevant.

46

We have two series of preferred stock outstanding, 5.25% Mandatory Convertible Preferred Stock, Series A and the Series B Preferred Stock, with dividend rates of 5.25% and 5.50%, respectively. Dividends are payable quarterly in arrears, subject to declaration by our Board of Directors.

During the three months ended March 31, 2015, we paid approximately $150.7 million to our common stockholders of record at the close of business on December 16, 2014. In addition, we declared a distribution of approximately $177.7 million payable to our common stockholders of record at the close of business on April 10, 2015.

We accrue distributions on unvested restricted stock unit awards granted subsequent to January 1, 2012, which are payable upon vesting. As of March 31, 2015, the amount accrued for distributions payable related to unvested restricted stock units was $3.0 million. During the three months ended March 31, 2015, we paid $1.2 million of distributions upon the vesting of restricted stock units.

Additional information regarding our contractual debt obligations is set forth under the caption “Quantitative and Qualitative Disclosures about Market Risk” in Part I, Item 3 of this Quarterly Report on Form 10-Q. We classify uncertain tax positions as non-current income tax liabilities. We expect the unrecognized tax benefits to change over the next twelve months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe. However, based on the status of these items and the amount of uncertainty associated with the outcome and timing of audit settlements, we are currently unable to estimate the impact of the amount of such changes, if any, to previously recorded uncertain tax positions and have classified $25.0 million as Other non-current liabilities in the condensed consolidated balance sheet as of March 31, 2015. We also classified $24.0 million of accrued income tax related interest and penalties as Other non-current liabilities in the condensed consolidated balance sheet as of March 31, 2015.

Factors Affecting Sources of Liquidity

As discussed in the “Liquidity and Capital Resources” section of our Annual Report on Form 10-K for the year ended December 31, 2014, our liquidity is dependent on our ability to generate cash flow from operating activities, borrow funds under our credit facilities and maintain compliance with the contractual agreements governing our indebtedness. We believe that the debt agreements discussed below represent our material debt agreements that contain covenants, our compliance with which would be material to an investor’s understanding of our financial results and the impact of those results on our liquidity.

Restrictions Under Loan Agreements Relating to Our Credit Facilities. The loan agreements for the 2014 Credit Facility, the 2013 Credit Facility and the 2013 Term Loan contain certain financial and operating covenants and other restrictions applicable to us and our subsidiaries that are not designated as unrestricted subsidiaries on a consolidated basis. These include limitations on additional debt, distributions and dividends, guaranties, sales of assets and liens. The loan agreements also contain covenants that establish three financial tests with which we and our restricted subsidiaries must comply related to (i) total leverage, (ii) senior secured leverage and (iii) interest coverage, as set forth below. As of March 31, 2015, we were in compliance with each of these covenants.

Consolidated Total Leverage Ratio: This ratio requires that we not exceed a ratio of Total Debt to Adjusted EBITDA (each as defined in the loan agreements) of 7.25 to 1.00 for the fiscal quarters ended March 31, 2015 and June 30, 2015, 7.00 to 1.00 for the fiscal quarters ended September 30, 2015 and December 31, 2015 and 6.00 to 1.00 thereafter. Based on our financial performance for the 12 months ended March 31, 2015, we could incur approximately $5.8 billion of additional indebtedness and still remain in compliance with the ratio currently in effect (effectively, however, this ratio would be limited to approximately $5.3 billion to remain in compliance with the covenant described immediately below). In addition, if we maintain our existing debt levels and our expenses do not change materially from current levels, our revenues could decrease by approximately $805 million and we would still remain in compliance with the ratio currently in effect.

48

Consolidated Senior Secured Leverage Ratio: This ratio requires that we not exceed a ratio of Senior Secured Debt to Adjusted EBITDA (each as defined in the loan agreements) of 3.00 to 1.00. Based on our financial performance for the 12 months ended March 31, 2015, we could incur approximately $5.3 billion of additional Senior Secured Debt and still remain in compliance with this ratio. In addition, if we maintain our existing Senior Secured Debt levels and our expenses do not change materially from current levels, our revenues could decrease by approximately $1.8 billion and we would still remain in compliance with this ratio.

Interest Coverage Ratio: In the event our debt ratings fall below investment grade, we will be required to maintain a ratio of Adjusted EBITDA to Interest Expense (each as defined in the loan agreements) of not less than 2.50 to 1.00. Based on our financial performance for the 12 months ended March 31, 2015, our interest expense, which was $569 million for that period, could increase by approximately $617 million and we would still remain in compliance with this ratio. In addition, if our expenses do not change materially from current levels, our revenues could decrease by approximately $1.5 billion and we would still remain in compliance with this ratio.

The loan agreements for our credit facilities also contain reporting and information covenants that require us to provide financial and operating information within certain time periods. If we are unable to provide the required information on a timely basis, we would be in breach of these covenants.

Any failure to comply with the financial maintenance tests and operating covenants of the loan agreements for our credit facilities would not only prevent us from being able to borrow additional funds under these credit facilities, but would constitute a default under these credit facilities, which could result in, among other things, the amounts outstanding, including all accrued interest and unpaid fees, becoming immediately due and payable. If this were to occur, we may not have sufficient cash on hand to repay such indebtedness. The key factors affecting our ability to comply with the debt covenants described above are our financial performance relative to the financial maintenance tests defined in the loan agreements for these credit facilities and our ability to fund our debt service obligations. Based upon our current expectations, we believe our operating results during the next 12 months will be sufficient to comply with these covenants.

Restrictions Under Agreements Relating to the Securitization and the GTP Notes. The First Amended and Restated Loan and Security Agreement related to the Securitization (the “Loan Agreement”) and the indentures governing the GTP Notes (the “GTP Indentures”) include certain financial ratios and operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, American Tower Asset Sub, LLC and American Tower Asset Sub II, LLC (the “Borrowers”), and the issuers of the GTP Notes (the “GTP Issuers”) are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets subject to customary carve-outs for ordinary course trade payables and permitted encumbrances (as defined in the Loan Agreement or the applicable GTP Indenture).

Under the terms of the agreements, amounts due will be paid from the cash flows generated by the assets securing the nonrecourse loan relating to the Securitization (the “Loan”) or the GTP Notes (as applicable), which must be deposited, and thereafter distributed, solely pursuant to the terms of the applicable agreement. On a monthly basis, after payment of all required amounts under the applicable agreement, the excess cash flows generated from the operation of the assets securing the Loan or the GTP Notes are released to the Borrowers or the applicable GTP Issuer, which can then be distributed to, and used by, us. During the three months ended March 31, 2015, the Borrowers distributed excess cash to us of $198.2 million and the GTP Issuers distributed excess cash to us of $31.2 million.

In order to distribute this excess cash flow to us, the Borrowers and the GTP Issuers must maintain a specified debt service coverage ratio (“DSCR”), calculated as the ratio of the net cash flow (as defined in the Loan Agreement or the applicable GTP Indenture) to the amount of interest required to be paid over the succeeding twelve months on the principal amount of the Loan or the principal amount of the GTP Notes that will be outstanding on the payment date following such date of determination, plus the amounts payable for

49

trustee and servicing fees. If the DSCR with respect to the Secured Tower Revenue Securities, Series 2013-1A and Series 2013-2A issued in our Securitization (the “Securities”) or any series of GTP Notes issued by GTP Acquisition Partners I, LLC (“GTP Partners”) is equal to or below 1.30x (the “Cash Trap DSCR”) at the end of any calendar quarter and it continues for two consecutive calendar quarters, or if the DSCR with respect to any series of GTP Notes issued by GTP Cellular Sites, LLC (“GTP Cellular Sites”) is equal to or below the Cash Trap DSCR at the end of any calendar month and it continues for two consecutive calendar months, then all cash flow in excess of amounts required to make debt service payments, fund required reserves, pay management fees and budgeted operating expenses and make other payments required with respect to the particular series of Securities or GTP Notes under the Loan Agreement or GTP Indentures, as applicable, will be deposited into reserve accounts instead of being released to the Borrowers or the GTP Issuers. The funds in the reserve accounts will not be released to the Borrowers or GTP Partners for distribution to us unless the DSCR with respect to such series of Securities or GTP Notes exceeds the Cash Trap DSCR for two consecutive calendar quarters. Likewise, the funds in the reserve account will not be released to GTP Cellular Sites for distribution to us unless the DSCR with respect to such series of GTP Notes exceeds the Cash Trap DSCR for two consecutive calendar months.

Additionally, an “amortization period,” commences as of the end of any calendar quarter with respect to the Securities and the series of GTP Notes issued by GTP Partners, and as of the end of any calendar month with respect to the series of GTP Notes issued by GTP Cellular Sites, if the DSCR of such series equals or falls below 1.15x (the “Minimum DSCR”). The “amortization period” will continue to exist until the end of any calendar quarter with respect to the Securities and the series of GTP Notes issued by GTP Partners for which the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters. Similarly, the “amortization period” will continue to exist until the end of any calendar month with respect to the series of GTP Notes issued by GTP Cellular Sites, for which the DSCR exceeds the Minimum DSCR for two consecutive calendar months.

If on the anticipated repayment date, the outstanding principal amount with respect to any series of the GTP Notes or the component of the Loan corresponding to the applicable subclass of the Securities has not been paid in full, an “amortization period” will continue until such principal amount of the applicable series of GTP Notes or the component of the Loan corresponding to the applicable subclass of Securities is repaid in full.

During an amortization period, all excess cash flow and any amounts then in the reserve accounts because the Cash Trap DSCR was not met would be applied to pay principal of the applicable subclass of Securities or series of GTP Notes on each monthly payment date, and so would not be available for distribution to us. Further, additional interest will begin to accrue with respect to any subclass of the Securities or series of GTP Notes from and after the anticipated repayment date at a per annum rate determined in accordance with the Loan Agreement or the GTP Indentures, as applicable.

Consequently, a failure to meet the noted DSCR tests could prevent the Borrowers or GTP Issuers from distributing excess cash flow to us, which could affect our ability to fund our capital expenditures, including tower construction and acquisitions, meet REIT distribution requirements and make preferred stock dividend payments. If the Borrowers were to default on the Loan, the trustee could seek to foreclose upon or otherwise convert the ownership of the 5,195 wireless and broadcast communications towers that secure the Loan (the “Secured Towers”), in which case we could lose the Secured Towers and the revenue associated with those towers. In addition, upon occurrence and during an event of default, the trustee may, in its discretion or at direction of holders of more than 50% of the aggregate outstanding principal of any series of GTP Notes, declare such series of GTP Notes immediately due and payable, in which case any excess cash flow would need to be used to pay holders of such GTP Notes. Furthermore, if the GTP Issuers were to default on a series of the GTP Notes, the trustee may demand, collect, take possession of, receive, settle, compromise, adjust, sue for, foreclose or realize upon all or any portion of the 2,843 towers and 1,035 property interests and other related assets that secure the GTP Notes (the “GTP Secured Sites”) securing such series of the GTP Notes, in which case we could lose the GTP Secured Sites and the revenue associated with those assets.

As of March 31, 2015, the Borrowers’ DSCR was 10.49x. Based on the Borrowers’ net cash flow for the calendar quarter ended March 31, 2015, and the amount of interest, servicing fees and trustee fees payable over

50

the succeeding twelve months on the Loan, the Borrowers could endure a reduction of approximately $441.9 million in net cash flow before triggering the Cash Trap DSCR, and approximately $449.1 million in net cash flow before triggering the Minimum DSCR. As of March 31, 2015, the DSCR of GTP Partners and GTP Cellular Sites were 2.94x, and 2.54x, respectively. Based on the net cash flow of GTP Partners and GTP Cellular Sites for the calendar quarter ended March 31, 2015 and the amount of interest, servicing fees and trustee fees payable over the succeeding twelve months on the applicable series of GTP Notes, GTP Partners and GTP Cellular Sites could endure a reduction of approximately $70.9 million and $16.3 million, respectively, in net cash flow before triggering the Cash Trap DSCR, and approximately $77.4 million and $18.3 million, respectively, in net cash flow before triggering the Minimum DSCR.

As discussed above, we use our available liquidity and seek new sources of liquidity to refinance and repurchase our outstanding indebtedness. In addition, in order to fund capital expenditures, future growth and expansion initiatives and satisfy our REIT distribution requirements, we may need to raise additional capital through financing activities. If we determine that it is desirable or necessary to raise additional capital, we may be unable to do so, or such additional financing may be prohibitively expensive or restricted by the terms of our outstanding indebtedness. If we are unable to raise capital when our needs arise, we may not be able to fund capital expenditures, future growth and expansion initiatives, satisfy our REIT distribution requirements, pay preferred stock dividends or refinance our existing indebtedness.

In addition, our liquidity depends on our ability to generate cash flow from operating activities. As set forth under the caption “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014, we derive a substantial portion of our revenues from a small number of tenants and, consequently, a failure by a significant tenant to perform its contractual obligations to us could adversely affect our cash flow and liquidity.

For more information regarding the terms of our outstanding indebtedness, please see note 8 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as related disclosures of contingent assets and liabilities. We evaluate our policies and estimates on an ongoing basis, including those related to impairment of long-lived assets, asset retirement obligations, revenue recognition, rent expense, stock-based compensation, income taxes and accounting for business combinations and acquisitions of assets, which we discussed in our Annual Report on Form 10-K for the year ended December 31, 2014. Management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We have reviewed our policies and estimates to determine our critical accounting policies for the three months ended March 31, 2015. We have made no material changes to the critical accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2014.

Accounting Standards Update

For a discussion of recent accounting standards updates, see note 1 to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have entered into interest rate swap agreements to manage our exposure to variability in interest rates on debt in Colombia and South Africa. All of our interest rate swap agreements have been designated as cash flow hedges and have an aggregate notional amount of $73.9 million, interest rates ranging from 5.74% to 7.83% and expiration dates through April 2021.

Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of March 31, 2015, was comprised of $1,980.0 million under the 2014 Credit Facility, $400.0 million under the 2013 Credit Facility, $2,000.0 million under the 2013 Term Loan, $254.6 million under the Mexican loan, $70.9 million under the Uganda loan, $34.6 million under the South African facility after giving effect to our interest rate swap agreements, $38.3 million under the Colombian credit facility after giving effect to our interest rate swap agreement and $100.9 million under the BR Towers debentures. A 10% increase in current interest rates would result in an additional $2.3 million of interest expense for the three months ended March 31, 2015.

See Item 2 of this Quarterly Report on Form 10-Q under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” for more information regarding our liquidity.

Foreign Currency Risk

We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiaries and joint ventures internationally. Any transaction denominated in a currency other than the U.S. Dollar is 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 AOCI. We may enter into additional foreign currency financial instruments in anticipation of future transactions in order to minimize the impact of currency fluctuations. For the three months ended March 31, 2015, approximately 32% of our revenues and approximately 39% of our total operating expenses were denominated in foreign currencies.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in foreign currency exchange rates from the quoted foreign currency exchange rates at March 31, 2015. As of March 31, 2015, the analysis indicated that such an adverse movement would cause our revenues, operating results and cash flows to fluctuate by approximately 3%.

As of March 31, 2015, we have incurred intercompany debt, which is not considered to be permanently reinvested, and similar unaffiliated balances that were denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As this debt had not been designated as being a long-term investment in nature, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. An adverse change of 10% in the underlying exchange rates of our unsettled intercompany debt and similar unaffiliated balances would result in approximately $21.9 million of unrealized gains or losses that would be included in Other expense in our condensed consolidated statements of operations for the three months ended March 31, 2015.

52

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our principal executive officer and principal financial officer concluded that these disclosure controls and procedures were effective as of March 31, 2015 and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the three months ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

53

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We periodically become involved in various claims and lawsuits that are incidental to our business. In the opinion of management, after consultation with counsel, there are no matters currently pending that would, in the event of an adverse outcome, have a material impact on our consolidated financial position, results of operations or liquidity.

ITEM 1A. RISK FACTORS

There were no material changes to the risk factors discussed in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014.
