The accompanying consolidated and condensed consolidated financial statements have been prepared by American Tower Corporation (together with its subsidiaries, “ATC” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial information included herein is unaudited. However, the Company believes that all adjustments, which are of a normal and recurring nature, considered necessary for a fair presentation of its financial position and results of operations for such periods have been included herein. The consolidated and 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, 2021 (the “2021 Form 10-K”). The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the entire year.

Principles of Consolidation and Basis of Presentation—The accompanying consolidated and 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 method or as investments in equity securities, depending upon the Company’s ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions have been eliminated.

As of March 31, 2022, the Company holds (i) a 52% controlling interest in subsidiaries whose holdings consist of the Company’s operations in France, Germany, Poland and Spain (such subsidiaries collectively, “ATC Europe”) (Allianz and CDPQ (each as defined in note 11) hold the noncontrolling interests) and (ii) a 51% controlling interest in a joint venture whose holdings consist of the Company’s operations in Bangladesh (Confidence Tower Holdings Ltd. (“Confidence Group”) holds the noncontrolling interest). As of March 31, 2022, ATC Europe holds an 87% and an 83% controlling interest in subsidiaries that consist of the Company’s operations in Germany and Spain, respectively (PGGM holds the noncontrolling interests). See note 11 for a discussion of changes to the Company’s noncontrolling interests during the three months ended March 31, 2022 and 2021.

Change in Reportable Segments—During the fourth quarter of 2021, as a result of the Company’s acquisition of CoreSite Realty Corporation (“CoreSite,” and the acquisition, the “CoreSite Acquisition”), the Company updated its reportable segments to add a Data Centers segment. The Data Centers segment is within the Company’s property operations. The Company now reports its results in seven segments – U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services, which are discussed further in note 15. The change in reportable segments had no impact on the Company’s consolidated financial statements for any prior periods. Historical financial information included in this Quarterly Report on Form 10-Q (this “Quarterly Report”) has been adjusted to reflect the change in reportable segments.

Significant Accounting Policies—The Company’s significant accounting policies are described in note 1 to the Company’s consolidated financial statements included in the 2021 Form 10-K. There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2022.

Cash and Cash Equivalents and Restricted Cash—The reconciliation of cash and cash equivalents and restricted cash reported within the applicable balance sheet that sum to the total of the same such amounts shown in the statements of cash flows is as follows:

						Three Months Ended March 31,
						2022						2021
Cash and cash equivalents						$	1,941.5					$	1,913.6
Restricted cash						329.9						79.7
Total cash, cash equivalents and restricted cash						$	2,271.4					$	1,993.3

The increase in restricted cash during the three months ended March 31, 2022 was due to advance payments from a customer received during the year ended December 31, 2021.

Revenue—The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located and its data center facilities (the “lease component”) and from the reimbursement of costs incurred by the Company in operating the communications sites and data center facilities and supporting its customers’ equipment as well as other services and contractual rights (the “non-lease component”). Most of the Company’s revenue is derived from leasing arrangements and is accounted for as lease revenue unless the timing and pattern of revenue recognition of

---

the non-lease component differs from the lease component. If the timing and pattern of the non-lease component revenue recognition differs from that of the lease component, the Company separately determines the stand-alone selling prices and pattern of revenue recognition for each performance obligation. Revenue related to distributed antenna system (“DAS”) networks and fiber and other related assets results from agreements with customers are generally not accounted for as leases.

Non-lease property revenue—Non-lease property revenue consists primarily of revenue generated from DAS networks, fiber and other property related revenue. DAS networks and fiber arrangements generally require that the Company provide the tenant the right to use available capacity on the applicable communications infrastructure. Performance obligations are satisfied over time for the duration of the arrangements. Non-lease property revenue also includes revenue generated from interconnection services in the Company’s data center facilities. Interconnection services are generally contracted on a month-to-month basis and are cancellable by the Company or the data center customer at any time. Performance obligations are satisfied over time for the duration of the arrangements. Other property related revenue streams, which include site inspections, are not material on either an individual or consolidated basis. There were no material changes in the receivables, contract assets and contract liabilities from contracts with customers for the three months ended March 31, 2022.

Services revenue—The Company offers tower-related services in the United States. These services include site application, zoning and permitting (“AZP”) and structural analysis. There is a single performance obligation related to AZP and revenue is recognized over time based on milestones achieved, which are determined based on costs expected to be incurred. Structural analysis services may have more than one performance obligation, contingent upon the number of contracted services. Revenue is recognized at the point in time the services are completed.

A summary of revenue disaggregated by source and geography is as follows:

Accounting Standards Updates

In March 2020, the Financial Accounting Standards Board (the “FASB”) issued guidance to provide optional expedients and exceptions for applying accounting principles generally accepted in the United States to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The guidance applies only to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an

The Company determines if an arrangement is a lease at the inception of the agreement. The Company considers an arrangement to be a lease if it conveys the right to control the use of the communications infrastructure or ground space underneath communications infrastructure for a period of time in exchange for consideration. The Company is both a lessor and a lessee.

During the three months ended March 31, 2022, the Company made no changes to the methods described in note 4 to its consolidated financial statements included in the 2021 Form 10-K. As of March 31, 2022, the Company does not have any material related party leases as either a lessor or a lessee. To the extent there are any intercompany leases, these are eliminated in consolidation.

Lessor— Historically, the Company has been able to successfully renew its applicable leases as needed to ensure continuation of its revenue. Accordingly, the Company assumes that it will have access to the land underneath its sites when calculating future minimum rental receipts. Future minimum rental receipts expected under non-cancellable operating lease agreements as of March 31, 2022 were as follows:

Fiscal Year						Amount (1)
Remainder of 2022						$	5,030.8
2023						7,198.2

_______________

(1)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, generally up to 20 years, as the Company considers these intangibles to be directly related to the tower assets.

The acquired network location intangibles represent the value to the Company of the incremental revenue growth that could potentially be obtained from leasing the excess capacity on acquired tower communications infrastructure. The acquired tenant-related intangibles typically represent the value to the Company of tenant contracts and relationships in

place at the time of an acquisition or similar transaction, including assumptions regarding estimated renewals. Other intangibles represent the value of acquired licenses, trade name and in place leases. In place lease value represents the fair value of costs avoided in securing data center customers, including vacancy periods, legal costs and commissions. In place lease value also includes assumptions on similar costs avoided upon the renewal or extension of existing leases on a basis consistent with occupancy assumptions used in the fair value of other assets.

The Company amortizes its acquired intangible assets on a straight-line basis over their estimated useful lives. As of March 31, 2022, the remaining weighted average amortization period of the Company’s intangible assets was 15 years. Amortization of intangible assets for the three months ended March 31, 2022 and 2021 was $458.6 million and $253.4 million, respectively. The increase in amortization expense is primarily due to intangible assets acquired since the beginning of the prior-year period, including as a result of the Telxius Acquisition and the CoreSite Acquisition. Based on current exchange rates, the Company expects to record amortization expense as follows over the remaining current year and the five subsequent years:

Fiscal Year						Amount

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 values of the Company’s financial assets and liabilities that are required to be measured on a recurring basis at fair value were as follows:

						March 31, 2022																		December 31, 2021
						Fair Value Measurements Using																		Fair Value Measurements Using
						Level 1						Level 2						Level 3						Level 1						Level 2						Level 3

_______________

(1)Investments in equity securities are recorded in Notes receivable and other non-current assets in the consolidated balance sheet at fair value. Unrealized holding gains and losses for equity securities are recorded in Other income (expense) in the consolidated statements of operations in the current period. During the three months ended March 31, 2022, the Company recognized unrealized gains of $9.5 million for equity securities held as of March 31, 2022.

(2)Included in the carrying values of the corresponding debt obligations.

During the three months ended March 31, 2022, the Company made no changes to the methods described in note 11 to its consolidated financial statements included in the 2021 Form 10-K that it used to measure the fair value of its interest rate swap agreements. In January 2022, the interest rate swap agreements with certain lenders under the 2.250% Notes expired upon maturity of the underlying debt. As of March 31, 2022, there were no amounts outstanding under the interest rate swap agreements under the 2.250% Notes.

---

 Items Measured at Fair Value on a Nonrecurring Basis

Assets Held and Used—The Company’s long-lived assets are recorded at amortized cost and, if impaired, are adjusted to fair value using Level 3 inputs. There were no material impairments during the three months ended March 31, 2022 and 2021. There were no other items measured at fair value on a nonrecurring basis during the three months ended March 31, 2022 or 2021.

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate (“ETR”) 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 ETR is determined. Under the provisions of the Internal Revenue Code of 1986, as amended, the Company may deduct amounts distributed to stockholders against the income generated by its real estate investment trust (“REIT”) operations. The Company continues to be subject to income taxes on the income of its domestic taxable REIT subsidiaries and income taxes in foreign jurisdictions where it conducts operations. In addition, the Company is able to offset certain income by utilizing its net operating losses, subject to specified limitations.

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 evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.

The decrease in the income tax provision during the three months ended March 31, 2022 as compared to the three months ended March 31, 2021 was primarily attributable to the reversal of valuation allowances in certain jurisdictions. These valuation allowance reversals were recognized as a reduction to the income tax provision as the net related deferred tax assets were deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability.

As of March 31, 2022 and December 31, 2021, the total unrecognized tax benefits that would impact the ETR, if recognized, were approximately $99.2 million and $94.8 million, respectively. The amount of unrecognized tax benefits during the three months ended March 31, 2022 includes additions to the Company’s existing tax positions of $1.7 million and foreign currency exchange rate fluctuations of $2.5 million. Unrecognized tax benefits are expected to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this time frame, as described in note 12 to the Company’s consolidated financial statements included in the 2021 Form 10-K. The impact of the amount of these changes to previously recorded uncertain tax positions could range from zero to $16.8 million.

The Company recorded the following penalties and income tax-related interest expense during the three months ended March 31, 2022 and 2021:

						Three Months Ended March 31,
						2022						2021
Penalties and income tax-related interest expense						$	7.3					$	3.7

As of March 31, 2022 and December 31, 2021, the total amount of accrued income tax related interest and penalties included in the consolidated balance sheets were $51.7 million and $42.3 million, respectively.

amended (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 for 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, generally over 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, 2022, the Company had the ability to grant stock-based awards with respect to an aggregate of 5.2 million shares of common stock under the 2007 Plan. In connection with the CoreSite Acquisition, the Company assumed the remaining shares previously available for issuance under a plan approved by the CoreSite shareholders, which converted into 1.4 million shares of the Company’s common stock. These shares will be available for issuance under the 2007 Plan, however, will only be available for grants to certain employees and will not be available for issuance beyond the period when they would have been available under the CoreSite plan, or March 20, 2023, at which time they will no longer be available for grant. In addition, the Company maintains an employee stock purchase plan (the “ESPP”) pursuant to which eligible employees may purchase shares of the Company’s common stock on the last day of each bi-annual offering period at a 15% discount from the lower of the closing market value on the first or last day of such offering period. The offering periods run from June 1 through November 30 and from December 1 through May 31 of each year.

During the three months ended March 31, 2022 and 2021, the Company recorded the following stock-based compensation expense in selling, general, administrative and development expense:

						Three Months Ended March 31,
						2022						2021
Stock-based compensation expense						$	56.7					$	38.0

Stock Options—As of March 31, 2022, there was no unrecognized compensation expense related to unvested stock options.

The Company’s option activity for the three months ended March 31, 2022 was as follows (shares disclosed in full amounts):

						Number of Options
Outstanding as of January 1, 2022						1,067,999
Exercised						(99,367)
Forfeited						—
Expired						—
Outstanding as of March 31, 2022						968,632

Restricted Stock Units—As of March 31, 2022, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan, including the CoreSite Replacement Awards (as defined below), was $260.9 million and is expected to be recognized over a weighted average period of approximately three years. Vesting of RSUs is subject generally to the employee’s continued employment or death, disability or qualified retirement (each as defined in the applicable RSU award agreement). In December 2021, in connection with the CoreSite Acquisition, the Company assumed and converted certain equity awards previously granted by CoreSite under its equity plan into corresponding equity awards with respect to shares of the Company’s common stock (the “CoreSite Replacement Awards”). As of March 31, 2022, total unrecognized compensation expense related to the CoreSite Replacement Awards was $17.3 million and is expected to be recognized over a weighted average period of approximately two years.

Performance-Based Restricted Stock Units—During the three months ended March 31, 2022, the Company’s Compensation Committee (the “Compensation Committee”) granted an aggregate of 98,542 PSUs (the “2022 PSUs”) to its executive officers and established the performance metrics for these awards. During the years ended December 31, 2021 and 2020, the Compensation Committee granted an aggregate of 98,694 PSUs (the “2021 PSUs”) and 110,925 PSUs (the “2020 PSUs”), respectively, to its executive officers and established the performance metrics for these awards. During the year ended December 31, 2020, in connection with the retirement of the Company’s former Chief Executive Officer, an aggregate of 40,186 shares underlying the 2020 PSUs were forfeited, which included the target number of shares issuable at the end of the three-year performance period for such executive’s 2020 PSUs. Threshold, target and maximum parameters were established for the metrics for a three-year performance period with respect to each of the 2022 PSUs, the 2021 PSUs and the 2020 PSUs and will be used to calculate the number of shares that will be issuable when each award vests, which may range from zero to 200% of the target amounts. At the end of each three-year performance period, the number of shares that vest will depend on the degree of achievement against the pre-established

---

performance goals. PSUs will be paid out in common stock at the end of each performance period, subject generally to the executive’s continued employment or death, disability or qualified retirement (each as defined in the applicable PSU award agreement). PSUs will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares that actually vest.

Restricted Stock Units and Performance-Based Restricted Stock Units—The Company’s RSU and PSU activity for the three months ended March 31, 2022 was as follows (shares disclosed in full amounts): 

			RSUs						PSUs

Sales under the 2020 ATM Program may be made by means of ordinary brokers’ transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to specific instructions of the Company, at negotiated prices. The Company intends to use the net proceeds from any issuances under the 2020 ATM Program for general corporate purposes, which may include, among other things, the funding of acquisitions, additions to working capital and repayment or refinancing of existing indebtedness. As of March 31, 2022, the Company has not sold any shares of common stock under the 2020 ATM Program.

Stock Repurchase Programs—In March 2011, the Company’s Board of Directors approved a stock repurchase program, pursuant to which the Company is authorized to repurchase up to $1.5 billion of its common stock (the “2011 Buyback”). In December 2017, the Board of Directors approved an additional stock repurchase program, pursuant to which the Company is authorized to repurchase up to $2.0 billion of its common stock (the “2017 Buyback,” and, together with the 2011 Buyback, the “Buyback Programs”).

Under the Buyback Programs, the Company is authorized to purchase shares from time to time through open market purchases, in privately negotiated transactions not to exceed market prices, and (with respect to such open market purchases) pursuant to plans adopted in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, in accordance with securities laws and other legal requirements and subject to market conditions and other factors.

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.

Verizon Transaction—In March 2015, the Company entered into an agreement with various operating entities of Verizon Communications Inc. (“Verizon”) that currently provides for the lease, sublease or management of approximately 11,250 wireless communications sites 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 rights 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 that tranche. The purchase price for each tranche is a fixed amount stated in the lease for such tranche plus the fair market value of certain alterations made to the related towers. 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 2,000 towers commencing between December 2000 and August 2004. Substantially all of the towers are part of the securitization transactions completed in March 2013 and March 2018. The average term of the lease or sublease for all communications 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 lease for that site plus the fair market value of certain alterations made to the related tower by AT&T. As of March 31, 2022, the Company has purchased an aggregate of approximately 400 of the subleased towers which are subject to the applicable agreement. The aggregate purchase option price for the remaining towers leased and subleased is $1.1 billion and includes per annum accretion through the applicable expiration of the lease or sublease of a site. For all such sites, AT&T has the right to continue to lease the reserved space through June 30, 2025 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 five successive five-year terms.

Other Contingencies—The Company is subject to income tax and other taxes in the geographic areas where it holds assets or operates, and periodically receives notifications of audits, assessments or other actions by taxing authorities. Taxing authorities may issue notices or assessments while audits are being conducted. In certain jurisdictions, taxing authorities may issue assessments with minimal examination. These notices and assessments do not represent amounts that the Company is obligated to pay and are often not reflective of the actual tax liability for which the Company will ultimately be liable. In the process of responding to assessments of taxes that the Company believes are not enforceable, the Company avails itself of both administrative and judicial remedies. The Company evaluates the circumstances of each notification or assessment based on the information available and, in those instances in which the Company does not anticipate a successful defense of positions taken in its tax filings, a liability is recorded in the appropriate amount based on the underlying assessment.

On December 5, 2016, the Company received an income tax assessment of Essar Telecom Infrastructure Private Limited (“ETIPL”) from the India Income Tax Department (the “Tax Department”) for the fiscal year ending 2008 in the amount of INR 4.75 billion ($69.8 million on the date of assessment) related to capital contributions. The Company challenged the assessment before the Office of Commissioner of Income Tax - Appeals, which ruled in the Company’s favor in January 2018. However, the Tax Department has appealed this ruling at a higher appellate authority. The Company estimates that there is a more likely than not probability that the Company’s position will be sustained upon appeal. Accordingly, no liability has been recorded. Additionally, the assessment was made with respect to transactions that took place in the tax year commencing in 2007, prior to the Company’s acquisition of ETIPL. Under the Company’s definitive acquisition agreement with 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.

Impact of current year acquisitions—The Company typically acquires communications sites and other communications infrastructure assets from wireless carriers or other tower operators and subsequently integrates those sites and related assets into its existing portfolio of communications sites and related assets. In the United States, the Company has also acquired data center facilities and related assets, including through the CoreSite Acquisition, as discussed below. The financial results of the Company’s acquisitions have been included in the Company’s consolidated statements of operations for the three months ended March 31, 2022 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 depend on, 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. Communications sites acquired from communications service providers may never have been operated as a business and may instead have been utilized solely by the seller as a component of its network infrastructure. An acquisition may or may not involve the transfer of business operations or employees.

The Company evaluates each of its acquisitions under the accounting guidance framework to determine whether to treat an acquisition as an asset acquisition or a business combination. For those transactions treated as asset acquisitions, the purchase price is allocated to the assets acquired, with no recognition of goodwill.

For those acquisitions accounted for as business combinations, the Company recognizes acquisition and merger related expenses in the period in which they are incurred and services are received; for transactions accounted for as asset acquisitions, these costs are capitalized as part of the purchase price. Acquisition and merger related costs may include finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees and general administrative costs directly related to completing the transaction. Integration costs include incremental and non-recurring costs necessary to convert data and systems, retain employees and otherwise enable the Company to operate acquired businesses or assets efficiently. The Company records acquisition and merger related expenses for business combinations, as well as integration costs for all acquisitions, in Other operating expenses in the consolidated statements of operations.

During the three months ended March 31, 2022 and 2021, the Company recorded acquisition and merger related expenses for business combinations and non-capitalized asset acquisition costs and integration costs as follows:

						Three Months Ended March 31,
						2022						2021
Acquisition and merger related expenses						$	5.7					$	34.6
Integration costs						$	10.0					$	16.6

During the three months ended March 31, 2022 and 2021, the Company also recorded benefits of $1.6 million and $4.0 million, respectively, related to pre-acquisition contingencies and settlements.

2022 Transactions

The estimated aggregate impact of the acquisitions completed in 2022 on the Company’s revenues and gross margin for the three months ended March 31, 2022 was not material to the Company’s operating results. The revenues and gross margin amounts also reflect incremental revenues from the addition of new customers to communications infrastructure assets subsequent to the transaction date.

Other Acquisitions—During the three months ended March 31, 2022, the Company acquired a total of 27 communications sites, as well as other communications infrastructure assets, in the United States, Canada and Nigeria for an aggregate purchase price of $29.1 million. These acquisitions were accounted for as asset acquisitions.

Other Signed Acquisitions

Orange Acquisition—On November 28, 2019, the Company entered into definitive agreements with Orange S.A. for the acquisition of up to approximately 2,000 communications sites in France over a period of up to five years for total consideration in the range of approximately 500.0 million EUR to 600.0 million EUR (approximately $550.5 million to $660.5 million at the date of signing) to be paid over the five-year term. The Company completed the acquisition of 1,197 of these communications sites during the years ended December 31, 2020 and 2021. The remaining communications sites are expected to continue to close in tranches, subject to customary closing conditions.

2021 Transactions

Telxius Acquisition—On January 13, 2021, the Company entered into two agreements with Telxius Telecom, S.A. (“Telxius”), a subsidiary of Telefónica, S.A., pursuant to which the Company agreed to acquire Telxius’ European and Latin American tower divisions, comprising approximately 31,000 communications sites in Argentina, Brazil, Chile, Germany, Peru and Spain, for approximately 7.7 billion EUR (approximately $9.4 billion at the date of signing) (the “Telxius Acquisition”), subject to certain adjustments. In June 2021, the Company completed the acquisition of nearly 20,000 communications sites in Germany and Spain, for total consideration of approximately 6.3 billion EUR (approximately $7.7 billion at the date of closing), subject to certain post-closing adjustments and over 7,000 communications sites in Brazil, Peru, Chile and Argentina, for total consideration of approximately 0.9 billion EUR (approximately $1.1 billion at the date of closing), subject to certain post-closing adjustments.

On August 2, 2021, the Company completed the acquisition of the approximately 4,000 remaining communications sites in Germany pursuant to the Telxius Acquisition for 0.6 billion EUR (approximately $0.7 billion at the date of closing).

Of the aggregate purchase price, 243.3 million EUR (approximately $269.2 million), including post-closing adjustments, of deferred payments are due in September 2025 and are reflected in Other non-current liabilities in the consolidated balance sheet as of March 31, 2022. The acquired operations in Germany and Spain are included in the Europe property segment and the acquired operations in Brazil, Peru, Chile and Argentina are included in the Latin America property segment. The Telxius Acquisition was accounted for as a business combination and is subject to post-closing adjustments. During the three months ended March 31, 2022, certain adjustments were made to increase the purchase price by $2.6 million, decrease assets by $32.3 million and reduce liabilities by $31.9 million, with a corresponding increase in goodwill of $3.0 million. There were no other material post-closing adjustments. The full reconciliation and finalization of the assets acquired and liabilities assumed, including those subject to valuation, have not been completed and, as a result, there may be additional post-closing adjustments.

---

CoreSite Acquisition—On November 14, 2021, the Company entered into an agreement with CoreSite to acquire all issued and outstanding shares of CoreSite common stock at $170.00 per share. CoreSite’s portfolio consisted of 24 data center facilities and related assets in eight United States markets. On December 28, 2021, the Company completed the CoreSite Acquisition for total consideration of approximately $10.4 billion, including the assumption and repayment of CoreSite’s existing debt. The acquired assets and operations are included in the Data Centers segment. The CoreSite Acquisition was accounted for as a business combination and is subject to post-closing adjustments. Subsequent to the acquisition dates, certain adjustments were made to decrease assets by $0.2 million and reduce liabilities by $1.0 million, with a corresponding decrease in goodwill of $0.8 million. There were no other material post-closing adjustments. The full reconciliation and finalization of the assets acquired and liabilities assumed, including those subject to valuation, have not been completed and, as a result, there may be additional post-closing adjustments.

Pro Forma Consolidated Results (Unaudited)

The following table presents the unaudited pro forma financial results as if the 2022 acquisitions had occurred on January 1, 2021 and the 2021 acquisitions had occurred on January 1, 2020. The pro forma results, to the extent available, are based on historical information, and accordingly may not fully reflect the current operations of the acquired business. In addition, 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.

Property

Communications Sites and Related Communications Infrastructure—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 property operations.

Data Centers—During the fourth quarter of 2021, as a result of the CoreSite Acquisition, the Company established the Data Centers segment as a reportable segment. The Data Centers segment relates to data center facilities and related assets that the Company owns and operates in the United States. The Data Centers segment offers different services from, and requires different resources, skill sets and marketing strategies than, the existing property operating segment in the U.S. & Canada. Prior to this revision, the Company operated in five property business segments: (i) U.S. & Canada property, (ii) Asia-Pacific property (iii) Africa property, (iii) Europe property and (iv) Latin America property.

The change in reportable segments had no impact on the Company’s consolidated financial statements for any prior periods. Historical financial information included in this Quarterly Report has been adjusted to reflect the change in reportable segments.

As of March 31, 2022, the Company’s property operations consisted of the following:

•U.S. & Canada: property operations in Canada and the United States;

•Asia-Pacific: property operations in Australia, Bangladesh, India and the Philippines;

•Africa: property operations in Burkina Faso, Ghana, Kenya, Niger, Nigeria, South Africa and Uganda;

•Europe: property operations in France, Germany, Poland and Spain;

•Latin America: property operations in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Paraguay and Peru; and

•Data Centers: data center property operations in the United States.

Services—The Company’s Services segment offers tower-related services in the United States, including AZP and structural analysis, which primarily support its communications site leasing business, including the addition of new tenants and equipment on its communications sites. The Services segment is a strategic business unit that offers different services from, and requires different resources, skill sets and marketing strategies than, the property operating segments.

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 the 2021 Form 10-K and as updated in note 1 above. 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 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. 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 interests 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 consolidated statements of operations and consolidated balance sheets.

Summarized financial information concerning the Company’s reportable segments for the three months ended March 31, 2022 and 2021 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.

(1)Accrued and unpaid interest on USD denominated notes is payable in USD semi-annually in arrears and will be computed from the issue date on the basis of a 360-day year comprised of twelve 30-day months.

(2)The Company may redeem the Notes at any time, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes plus a make-whole premium, together with accrued interest to the redemption date. If the Company redeems the Notes on or after the par call date, the Company will not be required to pay a make-whole premium.

---

If the Company undergoes a change of control and corresponding ratings decline, each as defined in the supplemental indenture for the Notes, the Company may be required to repurchase all of the Notes at a purchase price equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The Notes rank equally with all of the Company’s other senior unsecured debt and are structurally subordinated to all existing and future indebtedness and other obligations of its subsidiaries.

The supplemental indenture contains certain covenants that restrict the Company’s ability to merge, consolidate or sell assets and its (together with its subsidiaries’) ability to incur liens. These covenants are subject to a number of exceptions, including that the Company and its subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness if the aggregate amount of indebtedness secured by such liens does not exceed 3.5x Adjusted EBITDA, as defined in the supplemental indenture.
