合并原则和报告基础附表的合并和简明合并基本报表包括公司及其控股的实体的账户。公司对其无控制权的实体的投资根据公司对其经营和财务政策能否施加重大影响,采用股权法或作为股权证券投资来进行核算。所有公司之间的账户和交易已进行了抵消。
截至2024年9月30日,公司持有 (i) a 52持股包括公司在法国、德国和西班牙的业务的子公司(此类子公司统称为 “ATC Europe”)的控股权百分比(安联和CDPQ(定义见附注11)持有非控股权益),(ii) a 51合资企业的控股权百分比,该合资企业的控股权包括公司在孟加拉国的业务(信心大厦控股有限公司(“信心集团”)持有非控股权益)以及(iii)控股普通股权益约为 72该公司美国数据中心业务(Stonepeak(定义和进一步讨论见附注11)的百分比约为 28已发行普通股的百分比和 100未偿还的强制性可转换优先股的百分比)。截至 2024 年 9 月 30 日,ATC Europe 将举行 87% 和 83分别由公司在德国和西班牙的业务组成的子公司的控股权百分比(pgGM持有非控股权益)。有关截至2024年9月30日和2023年9月30日的九个月中公司非控股权益变动的讨论,请参阅附注11。

资产分类为待售者按携带价值或预估公平价值的较低者报告,减去预估卖出成本,不列入折旧。公司在每个资产被分类为待售的报告期内重新评估待售资产的公平价值减去卖出成本。待售资产的增值(损失)记录在附带的综合营业收入财务报表中。

Accounting Standards Updates—In November 2023, the Financial Accounting Standards Board (“FASB”) issued guidance, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
In December 2023, the FASB issued guidance which requires public entities to provide enhanced income tax disclosures on an annual basis. The new guidance requires an expanded rate reconciliation and the disaggregation of cash taxes paid by U.S. federal, U.S. state and foreign jurisdictions. The updated guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
SEC Rule Changes In March 2024, the SEC issued Final Rule No. 33-11275, “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” If such rule remains in effect, the rule will require registrants to provide certain climate-related information in their registration statements and annual reports. The rule requires registrants to provide climate related disclosures, including, but not limited to, (i) material Scope 1 and Scope 2 greenhouse gas emissions, (ii) governance and oversight of material climate-related risks, (iii) the material impact of climate risks on the registrant’s strategy, business model and outlook, (iv) risk management processes for material climate-related risks and (v) material climate targets and goals. The rule also requires disclosure of (x) financial statement effects of severe weather events and other natural conditions, (y) carbon offset and renewable energy credit information and (z) the impact of severe weather events and other natural conditions on estimates and assumptions. Disclosure requirements will begin phasing in for fiscal years beginning on or after January 1, 2025. In April 2024, the SEC issued an order staying implementation of such rule pending the resolution of certain challenges. The outcome of ongoing litigation is currently unknown. The Company is currently evaluating the potential impact of such rule on its consolidated financial statements and disclosures.

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 nine months ended September 30, 2024, the Company made no changes to the methods described in note 4 to its consolidated financial statements included in the 2023 Form 10-K. As of September 30, 2024, 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 communications infrastructure or ground space underlying its sites when calculating future minimum rental receipts through the end of the respective terms. Future minimum rental receipts expected under non-cancellable operating lease agreements as of September 30, 2024 were as follows:
Fiscal Year Amount (1) (2) (3)
Remainder of 2024$1,995.3 
20257,641.2 
20267,267.2

Thereafter25,016.8 
Total$54,807.5 
_______________
(1)Balances are translated at the applicable period-end exchange rate, which may impact comparability between periods.    
(2)Balances represent contractual amounts owed with no adjustments made for expected collectibility.
(3)Balances reflect a reduction of the future minimum rental receipts due to the ATC TIPL Transaction (as defined in note 15).
If incentives are present in the Company’s leases, they are evaluated to determine proper treatment and, to the extent present, are recorded in Other current assets and Other non-current assets in the consolidated balance sheets and amortized on a straight line basis over the corresponding lease term as a non-cash reduction to revenue. As of September 30, 2024, the remaining weighted average amortization period of the Company’s lease incentives was 10 years. As of September 30, 2024, Other current assets and Other non-current assets include $36.6 million and $337.7 million, respectively, for lease incentives.

Lessee—The Company assesses its right-of-use asset and other lease-related assets for impairment, as described in note 1 to the Company’s consolidated financial statements included in the 2023 Form 10-K. There were no material impairments recorded related to these assets during the three and nine months ended September 30, 2024 and 2023.
The Company leases certain land, buildings, equipment and office space under operating leases and land and improvements, towers, equipment and vehicles under finance leases. As of September 30, 2024, operating lease assets were included in Right-of-use asset and finance lease assets were included in Property and equipment, net in the consolidated balance sheet. During the nine months ended September 30, 2024, there were no material changes in the terms and provisions of the Company’s operating leases in which the Company is a lessee, other than those related to the change in estimated useful lives as described in note 1. As a result of the change in estimated useful lives of its assets, the Company reviewed its lease portfolio to determine whether additional renewal options were likely to be exercised. The Company concluded that these incremental renewals were lease modifications and has accounted for them accordingly. The extension of the asset lives resulted in an approximately $515 million increase in the right of use asset, as additional renewal options may be included, with an offsetting adjustment made to increase the related operating lease liability. There were no material changes in finance lease assets and liabilities during the nine months ended September 30, 2024.

India Goodwill Impairment
The Company reviews goodwill for impairment annually (as of December 31) or whenever events or circumstances indicate the carrying amount of an asset may not be recoverable, as further discussed in note 1 to its consolidated financial statements included in the 2023 Form 10-K.
The Company concluded that a triggering event occurred as of September 30, 2023 with respect to its India reporting unit primarily due to indications of value received from third parties in connection with the Company’s review of various strategic alternatives for its India operations, which concluded in the ATC TIPL Transaction. As a result, the Company performed an interim quantitative goodwill impairment test as of September 30, 2023, using, among other things, the information obtained from third parties to compare the estimated fair value of the India reporting unit to its carrying amount, including goodwill. The result of the Company’s interim goodwill impairment test as of September 30, 2023 indicated that the carrying amount of the Company's India reporting unit exceeded its estimated fair value.

(1)As of September 30, 2024, reflects the change in estimated useful lives as described in note 1.
(2)Beginning January 1, 2024, acquired network location intangibles are amortized over the remaining estimated useful life of the tower, taking into account residual value, generally up to 30 years, as the Company considers these intangibles to be directly related to the tower assets. Prior to January 1, 2024, acquired network location intangibles were amortized over the shorter of the term of the corresponding ground lease, taking into consideration lease renewal options and residual value, or the estimated useful life of the tower, generally up to 20 years.
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 September 30, 2024, the remaining weighted average amortization period of the Company’s intangible assets was 20 years. Amortization of intangible assets for the three and nine months ended September 30, 2024 was $221.4 million and $675.0 million, respectively. Amortization of intangible assets for the three and nine months ended September 30, 2023 was $338.8 million and $1.0 billion, respectively. Based on current exchange rates, the Company expects to record amortization expense as follows over the remainder of the current year and the five subsequent years:

(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. Interest on EUR-denominated notes is payable in EUR annually and will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes, beginning on the issue date.
(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.
(3)The 3.900% Notes and the 4.100% Notes are denominated in EUR; dollar amounts represent the equivalent issuance date aggregate principal amount.

If the Company undergoes a change of control and corresponding ratings decline, each as defined in the applicable 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 aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The Notes rank equally in right of payment with all of the Company’s other senior unsecured debt obligations and are structurally subordinated to all existing and future indebtedness and other obligations of its subsidiaries.
The supplemental indentures contain 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 applicable supplemental indenture.

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 1Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2Observable 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 3Unobservable 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 BasisThe 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:

VIL Optionally Convertible Debentures—In February 2023, and as amended in August 2023, one of the Company’s customers in India, Vodafone Idea Limited (“VIL”), issued optionally convertible debentures (the “VIL OCDs”) to the Company’s subsidiary, ATC TIPL, in exchange for VIL’s payment of certain amounts towards accounts receivables. The VIL OCDs were (a) to be repaid by VIL with interest or (b) convertible into equity of VIL. The VIL OCDs were issued for an aggregate face value of 16.0 billion INR (approximately $193.2 million on the date of issuance). The VIL OCDs were to mature in tranches with 8.0 billion INR (approximately $96.6 million on the date of issuance) maturing on August 27, 2023 and 8.0 billion INR (approximately $96.6 million on the date of issuance) maturing on August 27, 2024. In August 2023, the Company amended the agreements governing the VIL OCDs to, among other items, extend the maturity of the first tranche of the VIL OCDs to August 27, 2024. The fair value of the VIL OCDs at issuance was approximately $116.5 million. The VIL OCDs accrued interest at a rate of 11.2% annually. Interest was payable to ATC TIPL semi-annually, with the first payment received in September 2023.

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 long-lived asset impairments during the three and nine months ended September 30, 2024 or 2023 and there were no significant unobservable inputs used to determine the fair value of long-lived assets during the three and nine months ended September 30, 2024 or 2023.
During the nine months ended September 30, 2023, the Company undertook a process to evaluate various strategic alternatives with respect to its India operations, which resulted in the ATC TIPL Transaction. As part of this process, the Company received indications of value from third parties, which were less than the carrying value of the India reporting unit. The Company incorporated this information as a significant input used to determine the fair value of the India reporting unit as of September 30, 2023. During the three and nine months ended September 30, 2023, the Company recorded a goodwill impairment of $322.0 million, as discussed further in note 4.
There were no other items measured at fair value on a nonrecurring basis during the three and nine months ended September 30, 2024 or 2023.
Fair Value of Financial Instruments—The Company’s financial instruments for which the carrying value reasonably approximates fair value at September 30, 2024 and December 31, 2023 include 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 September 30, 2024 and December 31, 2023, the carrying value of long-term obligations, including the current portion, and amounts presented as discontinued operations, was $37.1 billion and $38.9 billion, respectively. As of September 30, 2024, the fair value of long-term obligations, including the current portion, was $35.7 billion, of which $31.2 billion was measured using Level 1 inputs and $4.5 billion was measured using Level 2 inputs. As of December 31, 2023, the fair value of long-term obligations, including the current portion, and amounts presented as discontinued operations, was $36.7 billion, of which $30.0 billion was measured using Level 1 inputs and $6.7 billion was measured using Level 2 inputs.

8.    INCOME TAXES
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 earnings 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.
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. Valuation allowances may be reversed if, based on changes in facts and circumstances, the net deferred tax assets have been determined to be realizable.
The increases in the income tax provision during the three and nine months ended September 30, 2024 were primarily attributable to increased earnings in certain foreign jurisdictions, partially due to the impacts of the change in estimated useful lives on depreciation and amortization expense as described in note 1. Additionally, the income tax provision for the three and nine months ended September 30, 2024 includes increases in tax expense due to unrealized gains from equity securities in the United States and anticipated foreign audit settlements. The income tax provision for the nine months ended September 30, 2023 includes a benefit from the application of a tax law change in Kenya.

As of September 30, 2024 and December 31, 2023, the total unrecognized tax benefits that would impact the ETR, if recognized, were approximately $113.3 million and $116.9 million, respectively. The amount of unrecognized tax benefits during the three and nine months ended September 30, 2024 includes (i) additions to the Company’s existing tax positions of $8.4 million and $10.9 million, respectively, (ii) reductions due to foreign currency exchange rate fluctuations of $1.8 million and $9.0 million, respectively, (iii) reductions due to the expiration of statutes of limitation of $0.8 million and $2.2 million, respectively, and (iv) reductions to the Company’s prior year tax positions and settlements of $3.3 million for the nine months ended September 30, 2024. 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 2023 Form 10-K. The impact of the amount of these changes to previously recorded uncertain tax positions could range from zero to $16.7 million.

The Company recorded the following penalties and income tax-related interest expense during the three and nine months ended September 30, 2024 and 2023:
Three Months Ended September 30,Nine Months Ended September 30,
2024202320242023
Penalties and income tax-related interest expense$12.4 $2.6 $21.9 $6.4 
As of September 30, 2024 and December 31, 2023, the total amount of accrued income tax related interest and penalties included in the consolidated balance sheets were $63.5 million and $49.1 million, respectively.
9.    STOCK-BASED COMPENSATION
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 Company’s 2007 Equity Incentive Plan, as 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. Awards granted prior to March 10, 2023 generally vest over four years for time-based restricted stock units (“RSUs”) and stock options. In December 2022, the Company’s Compensation Committee changed the terms of its awards to generally vest over three years. The change in vesting terms is applicable for new awards granted beginning on March 10, 2023 and does not change the vesting terms applicable to grants awarded prior to March 10, 2023. Performance-based restricted stock units (“PSUs”) generally vest over three years. Stock options generally expire ten years from the date of grant. As of September 30, 2024, the Company had the ability to grant stock-based awards with respect to an aggregate of 3.3 million shares of common stock under the 2007 Plan. 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 and nine months ended September 30, 2024 and 2023, the Company recorded the following stock-based compensation expense in selling, general, administrative and development expense:

Stock Options—As of September 30, 2024, there was no unrecognized compensation expense related to unvested stock options.
The Company’s option activity for the nine months ended September 30, 2024 was as follows (shares disclosed in full amounts):
Number of Options
Outstanding as of January 1, 2024766,955 
Exercised(330,279)
Forfeited 
Expired 
Outstanding as of September 30, 2024436,676 
Restricted Stock Units—As of September 30, 2024, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $177.5 million and is expected to be recognized over a weighted average period of approximately two 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).
Performance-Based Restricted Stock Units—During the nine months ended September 30, 2024, the Company’s Compensation Committee (the “Compensation Committee”) granted an aggregate of 87,550 PSUs (the “2024 PSUs”) to its executive officers and established the performance and market metrics for these awards. During the years ended December 31, 2023 and 2022, the Compensation Committee granted an aggregate of 118,684 PSUs (the “2023 PSUs”) and 98,542 PSUs (the “2022 PSUs”), respectively, to its executive officers and established the performance metrics for these awards. Threshold, target and maximum parameters were established for the metrics for a three-year performance period with respect to each of the 2024 PSUs, the 2023 PSUs and the 2022 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 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.
The 2024 PSUs include a market condition component based on relative total shareholder return as measured against the REIT constituents included in the S&P 500 Index. For the component of the 2024 PSUs subject to a market condition, fair value is determined using a Monte Carlo simulation model, which uses multiple input variables to determine the probability of satisfying the market condition requirements. The grant date fair value of the market condition component of the 2024 PSUs is $216.11.
Key assumptions used to apply this pricing model were as follows:
Nine Months Ended September 30, 2024
Expected term (years)2.81
Risk-free interest rate4.31 %
Annualized volatility26.75 %

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 more than 11,100 wireless communications sites, which commenced on March 27, 2015. The average term of the lease or sublease for all communications 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.

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 September 30, 2024, the Company has purchased an aggregate of approximately 700 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.
14.    BUSINESS SEGMENTS
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.

(tabular amounts in millions, unless otherwise noted)
The Company’s Services segment offers tower-related services in the United States, including AZP, structural and mount analyses, and construction management, which primarily support its 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 2023 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 and nine months ended September 30, 2024 and 2023 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.

15.    DISCONTINUED OPERATIONS
In 2023, the Company undertook a strategic review of its India operations, where the Company evaluated the appropriate level of exposure to the India market within its global portfolio of communications assets, and assessed opportunities to repurpose capital to drive long-term shareholder value and sustained growth. The strategic review concluded in January 2024 with the signed agreement for the ATC TIPL Transaction (as defined below).
On January 4, 2024, the Company, through ATC TIPL, entered into an agreement with Data Infrastructure Trust (“DIT”), an infrastructure investment trust sponsored by an affiliate of Brookfield Asset Management, pursuant to which DIT agreed to acquire a 100% ownership interest in ATC TIPL (the “ATC TIPL Transaction”). Per the terms of the agreement, total aggregate consideration would potentially represent up to approximately 210 billion Indian Rupees (“INR”) (approximately $2.5 billion), including the value of the VIL OCDs and the VIL Shares (each as defined and further discussed in note 7), payments on certain existing customer receivables, the repayment of existing intercompany debt and the repayment, or assumption, of the Company’s existing term loan in India, by DIT.
During the nine months ended September 30, 2024, ATC TIPL distributed approximately 29.6 billion INR (approximately $354.1 million) to the Company, which included the value of the VIL Shares and the VIL OCDs and the satisfaction of the economic benefit associated with the rights to payments on certain existing customer receivables. The distributions were deducted from the total aggregate consideration received by the Company at closing.
The ATC TIPL Transaction received all government and regulatory approvals during the three months ended September 30, 2024, and on September 12, 2024, the Company completed the sale of ATC TIPL and received total consideration of 182 billion INR (approximately $2.2 billion). The Company used the proceeds from the ATC TIPL Transaction to repay existing indebtedness under the 2021 Multicurrency Credit Facility.

(tabular amounts in millions, unless otherwise noted)
The Company recorded a loss on the sale of ATC TIPL of $1.2 billion, which primarily included the reclassification of the Company’s cumulative translation adjustment in India upon exiting the market of $1.1 billion.

Under the terms of the Company’s agreement with DIT, the Company is obligated to indemnify DIT with respect to certain tax-related liabilities that may arise from activities prior to the completion of the sale. The Company has recorded a $53.9 million contingent indemnification liability related to uncertain tax positions taken by ATC TIPL prior to the completion of the sale. The contingent indemnification liability is recorded in Other non-current liabilities in the consolidated balance sheets as of September 30, 2024.
The Company recorded a deferred tax asset related to the loss incurred on the sale of ATC TIPL which can only be utilized against future nonresident long-term India capital gains earned by ATC Asia Pacific Pte. Ltd. The Company believes that it is more likely than not that the benefit from this will not be realized and has recorded a full valuation allowance against this deferred tax asset of approximately $140 million.
For the year ended December 31, 2023, ATC TIPL represented approximately 23%, 15% and 15%, respectively, of the Company’s international property revenue, international gross margin and international operating profit and 10%, 6% and 5%, respectively, of the Company’s total property revenue, total segment gross margin and total segment operating profit. Prior to the completion of the ATC TIPL Transaction, ATC TIPL represented approximately 42% of the Company’s international communications sites and 34% of the Company’s total communications sites. The Company believes that the sale of ATC TIPL represents a strategic shift that will have a major impact on its operations and financial results, and as such, the divestiture qualified for presentation as discontinued operations. Prior to the divestiture and classification as discontinued operations, ATC TIPL’s operating results were included within the Asia-Pacific property segment. Accordingly, the operating results of ATC TIPL are reported as discontinued operations for all periods presented.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains statements about future events and expectations, or “forward-looking statements,” which relate to our goals, beliefs, strategies, plans or current expectations and other statements that are not of historical facts. For example, when we use words such as “project,” “plan,” “believe,” “anticipate,” “expect,” “forecast,” “estimate,” “intend,” “should,” “would,” “could,” “may” or other words that convey uncertainty of future events or outcomes, we are making forward-looking statements. Certain important factors may cause actual results to differ materially from those indicated by our forward-looking statements, including those factors set forth under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). Forward-looking statements represent management’s current expectations, beliefs and assumptions, and are inherently uncertain. We do not undertake any obligation to update our forward-looking statements.
The discussion and analysis of our financial condition and results of operations that follow are based upon our consolidated and condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). 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 consolidated and condensed consolidated financial statements herein and the accompanying notes, information set forth under the caption “Critical Accounting Policies and Estimates” in the 2023 Form 10-K, and in particular, the information set forth therein under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
In 2023, we undertook a strategic review of our India operations, where we evaluated the appropriate level of exposure to the India market within our global portfolio of communications assets, and assessed opportunities to repurpose capital to drive long-term shareholder value and sustained growth. The strategic review concluded in January 2024 with the signed agreement for the ATC TIPL Transaction (as defined below).
On January 4, 2024, we, through our subsidiaries, ATC Asia Pacific Pte. Ltd. and ATC Telecom Infrastructure Private Limited (“ATC TIPL”), which holds our operations in India, entered into an agreement with Data Infrastructure Trust (“DIT”), an infrastructure investment trust sponsored by an affiliate of Brookfield Asset Management, pursuant to which DIT agreed to acquire a 100% ownership interest in ATC TIPL (the “ATC TIPL Transaction”). Per the terms of the agreement, total aggregate consideration would potentially represent up to approximately 210 billion Indian Rupees (“INR”) (approximately $2.5 billion), including the value of the VIL OCDs and the VIL Shares (each as defined and further discussed below), payments on certain existing customer receivables, the repayment of existing intercompany debt and the repayment, or assumption, of our existing term loan in India, by DIT.
During the nine months ended September 30, 2024, ATC TIPL distributed approximately 29.6 billion INR (approximately $354.1 million) to us, which included the value of the VIL Shares and the VIL OCDs and the satisfaction of the economic benefit associated with the rights to payments on certain existing customer receivables. The distributions were deducted from the total aggregate consideration received by us at closing.
The ATC TIPL Transaction received all government and regulatory approvals during the three months ended September 30, 2024, and on September 12, 2024, we completed the sale of ATC TIPL and received total consideration of 182 billion INR (approximately $2.2 billion). We used the proceeds from the ATC TIPL Transaction to repay existing indebtedness under our $6.0 billion senior unsecured multicurrency revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Multicurrency Credit Facility”). We recorded a loss on the sale of ATC TIPL of $1.2 billion, which primarily included the reclassification of our cumulative translation adjustment in India upon exiting the market of $1.1 billion. The loss on sale of ATC TIPL is included in Loss from discontinued operations, net of taxes in the consolidated statements of operations for the three and nine months ended September 30, 2024.
The divestiture qualified for presentation as discontinued operations. See note 15 to our consolidated and condensed consolidated financial statements included in this Quarterly Report (“Note 15”) for further discussion. Prior to the divestiture and classification as discontinued operations, ATC TIPL’s operating results were included within the Asia-Pacific property segment. Historical financial information included in Management’s Discussion and Analysis of Financial Condition and Results of Operations has been adjusted to reflect the operating results of ATC TIPL as discontinued operations for all periods presented.

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 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. 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 other telecommunications infrastructure and property interests that we lease primarily to communications service providers and third-party tower operators, and, as discussed further below, we hold a portfolio of highly interconnected data center facilities and related assets in the United States. Our customers include our tenants, licensees and other payers. We refer to the business encompassing the above as our property operations, which accounted for 98% of our total revenues for each of the three and nine months ended September 30, 2024 and includes our U.S. & Canada property, Asia-Pacific property, Africa property, Europe property and Latin America property segments and Data Centers segment.
We also offer tower-related services in the United States, including site application, zoning and permitting, structural and mount analyses, and construction management, which primarily support our site leasing business, including the addition of new tenants and equipment on our sites.

We operate in seven reportable segments: U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services. In evaluating operating performance in each business segment, management uses, among other factors, segment gross margin and segment operating profit (see note 14 to our consolidated and condensed consolidated financial statements included in this Quarterly Report).
The 2023 Form 10-K contains information regarding management’s expectations of long-term drivers of demand for our communications sites, as well as key trends, which management believes provide valuable insight into our operating and financial resource allocation decisions. The discussion below should be read in conjunction with the 2023 Form 10-K and, in particular, the information set forth therein under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.”
In most of our markets, our tenant leases for our communications sites with wireless carriers generally have initial non-cancellable terms of five to ten years with multiple renewal terms. Accordingly, the vast majority of the revenue generated by our property operations during the nine months ended September 30, 2024 was recurring revenue that we should continue to receive in future periods. Most of our tenant leases for our communications sites have provisions that periodically increase or “escalate” the rent due under the lease, typically based on (a) an annual fixed escalation (averaging approximately 3% in the United States), (b) an inflationary index in most of our international markets, or (c) a combination of both. In addition, certain of our tenant leases provide for additional revenue primarily to cover costs (pass-through revenue), such as ground rent or power and fuel costs.
Based upon existing customer leases and foreign currency exchange rates as of September 30, 2024, we expect to generate nearly $55 billion of non-cancellable customer lease revenue over future periods, before the impact of straight-line lease accounting.
Following the rulings by the Supreme Court of India regarding carriers’ obligations for the adjusted gross revenue fees and charges prescribed by the court, we experienced variability and a level of uncertainty in collections in India. As further discussed in Item 1A of the 2023 Form 10-K under the caption “Risk Factors—A substantial portion of our current and projected future revenue is derived from a small number of customers, and we are sensitive to adverse changes in the creditworthiness and financial strength of our customers,” in the third quarter of 2022, one of our customers in India, Vodafone Idea Limited (“VIL”), communicated that it would make partial payments of its contractual amounts owed to us (the “VIL Shortfall”). We recorded reserves in late 2022 and the first half of 2023 for the VIL Shortfall. In the second half of 2023, VIL began making payments in full of its monthly contractual obligations owed to us.
37


In February 2023, and as amended in August 2023, VIL issued optionally convertible debentures (the “VIL OCDs”) to ATC TIPL in exchange for VIL’s payment of certain amounts towards accounts receivables. The VIL OCDs were issued for an aggregate face value of 16.0 billion Indian Rupees (“INR”) (approximately $193.2 million on the date of issuance). On March 23, 2024, we converted an aggregate face value of 14.4 billion INR (approximately $172.7 million) of VIL OCDs into 1,440 million shares of equity of VIL (the “VIL Shares”). On April 29, 2024, we completed the sale of 1,440 million VIL Shares at a price of 12.78 INR per share. The net proceeds for this transaction were approximately 18.0 billion INR (approximately $216.0 million at the date of settlement) after deducting commissions and fees. On June 5, 2024, we completed the sale of the remaining aggregate face value of 1.6 billion INR (approximately $19.2 million) of the VIL OCDs. The net proceeds for this transaction, excluding accrued interest, were approximately 1.8 billion INR (approximately $22.0 million at the date of settlement) after deducting fees. As of September 30, 2024, none of the VIL Shares or the VIL OCDs remained outstanding.
In 2023, we initiated a strategic review of our India business, as discussed above. During the process, and based on information gathered therein, we updated our estimate on the fair value of the India reporting unit and determined that the carrying value exceeded fair value. As a result, we recorded a goodwill impairment charge of $322.0 million in the third quarter of 2023.
ATC TIPL’s operating results are presented as discontinued operations. See Note 15 for further discussion.
The revenues generated by our property operations may be affected by cancellations of existing tenant leases. As discussed above, most of our tenant leases with wireless carriers and broadcasters are multiyear contracts, which typically are non-cancellable; however, in some instances, a lease may be cancelled upon the payment of a termination fee. Revenue lost from either tenant lease cancellations or the non-renewal of leases or rent renegotiations, which we refer to as churn, has historically not had a material adverse effect on the revenues generated by our consolidated property operations. During the nine months ended September 30, 2024, churn was approximately 2% of our tenant billings, primarily driven by churn in our U.S. & Canada property segment, as discussed below.
We expect that our churn rate in our U.S. & Canada property segment will remain elevated through 2025 due to contractual lease cancellations and non-renewals by T-Mobile, including legacy Sprint Corporation leases, pursuant to the terms of our master lease agreement with T-Mobile US, Inc. entered into in September 2020.
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”) attributable to American Tower Corporation common stockholders and Adjusted Funds From Operations (“AFFO”) attributable to American Tower Corporation common stockholders (“AFFO attributable to American Tower Corporation common stockholders”).
We define Adjusted EBITDA as Net income before Income (loss) from equity method investments; Income (loss) from discontinued operations, net of taxes; Income tax benefit (provision); Other income (expense); Gain (loss) on retirement of long-term obligations; Interest expense; Interest income; Other operating income (expense), including Goodwill impairment; Depreciation, amortization and accretion; and stock-based compensation expense.
Nareit FFO attributable to American Tower Corporation common stockholders 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 including adjustments and distributions for unconsolidated affiliates and noncontrolling interests and discontinued operations. In this section, we refer to Nareit FFO attributable to American Tower Corporation common stockholders as “Nareit FFO (common stockholders).”
We define AFFO attributable to American Tower Corporation common stockholders as Nareit FFO (common stockholders) before (i) straight-line revenue and expense; (ii) stock-based compensation expense; (iii) the deferred portion of income tax and other income tax adjustments; (iv) non-real estate related depreciation, amortization and accretion; (v) amortization of deferred financing costs, debt discounts and premiums and long-term deferred interest charges; (vi) other income (expense); (vii) gain (loss) on retirement of long-term obligations; and (viii) other operating income (expense); less cash payments related to capital improvements and cash payments related to corporate capital expenditures and including adjustments and distributions for unconsolidated affiliates and noncontrolling interests and adjustments for discontinued operations, which includes the impact of noncontrolling interests and discontinued operations on both Nareit FFO and the corresponding adjustments included in AFFO. In this section, we refer to AFFO attributable to American Tower Corporation common stockholders as “AFFO (common stockholders).”
38


Adjusted EBITDA, Nareit FFO (common stockholders) and AFFO (common stockholders) are not intended to replace net income or any other performance measures determined in accordance with GAAP. None of Adjusted EBITDA, Nareit FFO (common stockholders) or AFFO (common stockholders) represents 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 a measure of funds available to fund our cash needs, including our ability to make cash distributions. Rather, Adjusted EBITDA, Nareit FFO (common stockholders) and AFFO (common stockholders) are presented as we believe each is a useful indicator of our current operating performance. We believe that these metrics are useful to an investor in evaluating our operating performance because (1) each is a key measure used by our management team for decision making purposes and for evaluating our operating segments’ performance; (2) Adjusted EBITDA is a component underlying our credit ratings; (3) Adjusted EBITDA is widely used in the telecommunications real estate sector to measure operating performance as depreciation, amortization and accretion may vary significantly among companies depending upon accounting methods and useful lives, particularly where acquisitions and non-operating factors are involved; (4) AFFO (common stockholders) is widely used in the telecommunications real estate sector to adjust Nareit FFO (common stockholders) for items that may otherwise cause material fluctuations in Nareit FFO (common stockholders) growth from period to period that would not be representative of the underlying performance of property assets in those periods; (5) each provides investors with a meaningful measure for evaluating our period-to-period operating performance by eliminating items that are not operational in nature; and (6) each provides investors with a measure for comparing our results of operations to those of other companies, particularly those in our industry.
Our measurement of Adjusted EBITDA, Nareit FFO (common stockholders) and AFFO (common stockholders) may not, however, be fully comparable to similarly titled measures used by other companies. Reconciliations of Adjusted EBITDA, Nareit FFO (common stockholders) and AFFO (common stockholders) to net income, the most directly comparable GAAP measure, have been included below.

Depreciation, amortization and accretion$498.5 $723.2 (31)%$1,527.9 $2,203.6 (31)%
The decreases in depreciation, amortization and accretion expense for the three and nine months ended September 30, 2024 were primarily attributable to the change in estimated useful lives of our tower assets.
During the first quarter of 2024, we finalized our reviews of the estimated useful lives of our tower assets and estimated settlement dates for our asset retirement obligations. Based on information obtained, we determined that our estimated asset lives and our estimated settlement dates should be extended, which is expected to result in an estimated $730 million decrease in depreciation and amortization expense and an estimated $75 million decrease in accretion expense for the year ended December 31, 2024. For more information on the change in the estimated useful lives of our tower assets and the change in the estimated settlement dates for our asset retirement obligations, see the information under the captions “Property and Equipment” and “Asset Retirement Obligations” included in note 1 to our consolidated and condensed consolidated financial statements included in this Quarterly Report (“Note 1”).

Other operating expense$5.1 $26.6 (81)%$5.0 $213.2 (98)%
The decrease in other operating expense during the three months ended September 30, 2024 was primarily attributable to a decrease in impairment charges of $10.1 million and a decrease in integration and acquisition related costs, including benefits related to pre-acquisition contingencies and settlements. The decrease in other operating expense during the nine months ended September 30, 2024 was primarily attributable to a decrease in losses on sales or disposals of assets of $97.7 million, primarily attributable to the loss on the sale of Mexico Fiber of $80.0 million in the prior year period, a decrease in impairment charges of $78.2 million and a decrease in integration and acquisition related costs, including benefits related to pre-acquisition contingencies and settlements.

Total other expense$588.7 $88.7 564 %$1,117.3 $914.6 22 %

Total other expense consists primarily of interest expense and realized and unrealized foreign currency gains or losses as a result of foreign currency exchange rate fluctuations primarily associated with our intercompany notes and similar unaffiliated balances denominated in a currency other than the subsidiaries’ functional currencies.
The increase in total other expense during the three months ended September 30, 2024 was primarily due to foreign currency losses of $337.4 million in the current period, as compared to foreign currency gains of $239.0 million in the prior-year period. Total other expense during the three months ended September 30, 2024 also includes $67.9 million in unrealized gains from equity securities in the United States. The increase in total other expense during the nine months ended September 30, 2024 was primarily due to foreign currency losses of $231.4 million in the current period, as compared to foreign currency gains of $47.1 million in the prior-year period. Total other expense during the nine months ended September 30, 2024 also includes $93.9 million in unrealized gains from equity securities in the United States.

Effective tax rate22.2 %6.0 %12.6 %6.2 %
As a real estate investment trust for U.S. federal income tax purposes (“REIT”), we may deduct earnings distributed to stockholders against the income generated by our REIT operations. Consequently, the effective tax rate on income from continuing operations for the nine months ended September 30, 2024 and 2023 differs from the federal statutory rate.
The increases in the income tax provision during the three and nine months ended September 30, 2024 were primarily attributable to increased earnings in certain foreign jurisdictions, partially due to the impacts of the change in estimated useful lives on depreciation and amortization expense as described in Note 1. Additionally, the income tax provision for the three and nine months ended September 30, 2024 includes increases in tax expense related to unrealized gains from equity securities in the United States and anticipated foreign audit settlements. The income tax provision for the nine months ended September 30, 2023 includes a benefit from the application of a tax law change in Kenya. For more information on the change in the estimated useful lives of our tower assets, see the information under the caption “Property and Equipment” included in Note 1.

Loss from Discontinued Operations, Net of Taxes
The ATC TIPL Transaction received all government and regulatory approvals during the three months ended September 30, 2024. The divestiture qualified for presentation as discontinued operations. Accordingly, the operating results of ATC TIPL are reported as discontinued operations for all periods presented. Prior to the divestiture and classification as discontinued operations, ATC TIPL’s operating results were included within the Asia-Pacific property segment. See Note 15 for further discussion.
On September 12, 2024, we completed the ATC TIPL Transaction and received total consideration of 182 billion INR (approximately $2.2 billion). We used the proceeds from the ATC TIPL Transaction to repay existing indebtedness under the 2021 Multicurrency Credit Facility. We recorded a loss on the sale of ATC TIPL of $1.2 billion, which primarily included the reclassification of our cumulative translation adjustment in India upon exiting the market of $1.1 billion.

Net Income / Adjusted EBITDA and Net Income / Nareit FFO attributable to American Tower Corporation common stockholders / AFFO attributable to American Tower Corporation common stockholders 

During the nine months ended September 30, 2024, we updated our presentation of Nareit FFO attributable to American Tower Corporation common stockholders and AFFO attributable to American Tower Corporation common stockholders to remove the separate presentation of Consolidated AFFO. We believe this presentation better aligns our reporting with management’s current approach of allocating capital and resources, managing growth and profitability and assessing the operating performance of our business. The change in presentation has no impact on our Nareit FFO attributable to American Tower Corporation common stockholders or AFFO attributable to American Tower Corporation common stockholders for any periods.

Liquidity and Capital Resources
The information in this section updates as of September 30, 2024 the “Liquidity and Capital Resources” section of the 2023 Form 10-K and should be read in conjunction with that report.
Overview
During the nine months ended September 30, 2024, our significant financing transactions included:
Redemption of our 0.600% senior unsecured notes due 2024 (the “0.600% Notes”), our 5.00% senior unsecured notes due 2024 (the “5.00% Notes”) and our 3.375% senior unsecured notes due 2024 (the “3.375% Notes”) upon their maturity;
Registered public offering in an aggregate principal amount of $2.4 billion, including 1.0 billion EUR, of senior unsecured notes with maturities ranging from 2029 to 2034;
Repayment of 825.0 million EUR ($895.5 million as of the repayment date) unsecured term loan, as amended in December 2021 (the “2021 EUR Three Year Delayed Draw Term Loan”); and
Repayment of indebtedness under the 2021 Multicurrency Credit Facility using proceeds from the ATC TIPL Transaction.
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.
The following table summarizes the significant components of our liquidity (in millions):
As of September 30, 2024
Available under the 2021 Multicurrency Credit Facility$5,860.0

We use our cash flows to fund our operations and investments in our business, including maintenance and improvements, communications site and data center construction, managed network installations and 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 (the “Code”). We may also periodically repay or repurchase our existing indebtedness or equity. We typically fund our international expansion efforts primarily through a combination of cash on hand, intercompany debt and equity contributions.
As of September 30, 2024, we had total outstanding indebtedness of $37.4 billion, with a current portion of $3.7 billion. During the nine months ended September 30, 2024, we generated sufficient cash flow from operations, together with borrowings under our credit facilities, proceeds from our debt issuance and cash on hand, to fund our acquisitions, capital

expenditures and debt service obligations, as well as our required distributions. We believe the cash generated by operating activities during the year ending December 31, 2024, together with our borrowing capacity under our credit facilities, will suffice to fund our required distributions, capital expenditures, debt service obligations (interest and principal repayments) and signed acquisitions.
Material Cash Requirements— There were no material changes to the Material Cash Requirements section of the 2023 Form 10-K.
As of September 30, 2024, we had $1.6 billion of cash and cash equivalents held by our foreign subsidiaries. As of September 30, 2024, we had $327.5 million of cash and cash equivalents held by our joint ventures, of which $281.7 million was held by our foreign joint ventures. Certain foreign subsidiaries may pay us interest or principal on intercompany debt. Additionally, in the event that we repatriate funds from our foreign subsidiaries, we may be required to accrue and pay certain taxes.
Cash Flows from Operating Activities
The increase in cash provided by operating activities for the nine months ended September 30, 2024 was primarily attributable to (i) an increase in the operating profits of our U.S. & Canada, Asia-Pacific, Africa, and Europe property segments, our Data Centers segment, and in India, excluding the loss on sale of ATC TIPL, (ii) a decrease in the impact of straight-line revenue and (iii) a decrease in cash required for working capital, partially offset by increases in cash paid for interest and cash paid for taxes.
Cash Flows from Investing Activities

___________
(1)Accrued and unpaid interest on U.S. Dollar (“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. Interest on EUR denominated notes is payable in EUR annually and will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes, beginning on the issue date.
(2)We 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 we redeem the Notes on or after the par call date, we will not be required to pay a make-whole premium.
(3)The 3.900% Notes and the 4.100% Notes are denominated in EUR; dollar amounts represent the equivalent issuance date aggregate principal amount.
If we undergo a change of control and corresponding ratings decline, each as defined in the applicable supplemental indenture for the Notes, we may be required to repurchase all of the Notes at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The Notes rank equally in right of payment with all of our other senior unsecured debt obligations and are structurally subordinated to all existing and future indebtedness and other obligations of our subsidiaries.
The supplemental indentures contain certain covenants that restrict our ability to merge, consolidate or sell assets and our (together with our subsidiaries’) ability to incur liens. These covenants are subject to a number of exceptions, including that we and our 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 applicable supplemental indenture.
Bank Facilities
2021 Multicurrency Credit Facility—During the nine months ended September 30, 2024, we borrowed an aggregate of $4.6 billion, including 0.9 billion EUR ($1.0 billion as of the borrowing date) and repaid an aggregate of $5.2 billion, including 1.1 billion EUR ($1.2 billion as of the repayment date), of revolving indebtedness under the 2021 Multicurrency Credit Facility. We used the borrowings to repay outstanding indebtedness, including the 0.600% Notes, the 5.00% Notes and the 2021 EUR Three Year Delayed Draw Term Loan, and for general corporate purposes. As of September 30, 2024, there are no EUR borrowings outstanding under the 2021 Multicurrency Credit Facility. We used the proceeds from the ATC TIPL Transaction to repay existing indebtedness under the 2021 Multicurrency Credit Facility. We currently have $5.2 million of undrawn letters of credit and maintain the ability to draw down and repay amounts under the 2021 Multicurrency Credit Facility in the ordinary course.
2021 Credit Facility—During the nine months ended September 30, 2024, we borrowed an aggregate of $1.5 billion and repaid an aggregate of $2.1 billion of revolving indebtedness under our $4.0 billion senior unsecured revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Credit Facility”). We used the borrowings to repay outstanding indebtedness, including the 3.375% Notes, and for general corporate purposes. We currently have $30.4 million of undrawn letters of credit and maintain the ability to draw down and repay amounts under the 2021 Credit Facility in the ordinary course.
55


Repayment of 2021 EUR Three Year Delayed Draw Term Loan—On May 21, 2024, we repaid all amounts outstanding under the 2021 EUR Three Year Delayed Draw Term Loan using borrowings under the 2021 Multicurrency Credit Facility.
As of September 30, 2024, the key terms under the 2021 Multicurrency Credit Facility, the 2021 Credit Facility and our $1.0 billion unsecured term loan, as amended and restated in December 2021, as further amended (the “2021 Term Loan”), were as follows:

(1)Represents interest rate above: (a) SOFR for SOFR based borrowings, (b) Euro Interbank Offer Rate (“EURIBOR”) for EURIBOR based borrowings and (c) the defined base rate for base rate borrowings, in each case based on our debt ratings.
(2)Currently borrowed at SOFR.
(3)Subject to two optional renewal periods.

We must pay a quarterly commitment fee on the undrawn portion of each of the 2021 Multicurrency Credit Facility and the 2021 Credit Facility. The commitment fee for the 2021 Multicurrency Credit Facility and the 2021 Credit Facility ranges from 0.080% to 0.200% per annum, based upon our debt ratings, and is currently 0.110%.
The 2021 Multicurrency Credit Facility, the 2021 Credit Facility and the 2021 Term Loan and the associated loan agreements (the “Bank Loan Agreements”) do not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium. We have the option of choosing either a defined base rate, SOFR or EURIBOR as the applicable base rate for borrowings under these bank facilities.
Each Bank Loan Agreement contains certain reporting, information, financial and operating covenants and other restrictions (including limitations on additional debt, guaranties, sales of assets and liens) with which we must comply. Failure to comply with these financial and operating covenants could not only prevent us from being able to borrow additional funds under the revolving credit facilities, but may constitute a default, which could result in, among other things, the amounts outstanding under the applicable agreement, including all accrued interest and unpaid fees, becoming immediately due and payable.
India Term Loan—On February 17, 2023, we borrowed 10.0 billion INR (approximately $120.7 million at the date of borrowing) under an unsecured term loan in India with a maturity date that is one year from the date of the first draw thereunder (the “India Term Loan”). In January 2024, we amended the India Term Loan to extend the maturity date to December 31, 2024. On September 12, 2024, in connection with the completion of the ATC TIPL Transaction, we repaid the India Term Loan.
Stock Repurchase Programs—In March 2011, our Board of Directors approved a stock repurchase program, pursuant to which we are authorized to repurchase up to $1.5 billion of our common stock (the “2011 Buyback”). In December 2017, our Board of Directors approved an additional stock repurchase program, pursuant to which we are authorized to repurchase up to $2.0 billion of our common stock (the “2017 Buyback,” and, together with the 2011 Buyback, the “Buyback Programs”).
During the nine months ended September 30, 2024, there were no repurchases under either of the Buyback Programs.
We expect to continue managing the pacing of the remaining approximately $2.0 billion under the Buyback Programs in response to general market conditions and other relevant factors. We expect to fund any further repurchases of our common stock through a combination of cash on hand, cash generated by operations and borrowings under our credit facilities. Repurchases under the Buyback Programs are subject to, among other things, us having available cash to fund the 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 plan. During the nine months ended
56


September 30, 2024, we received an aggregate of $38.1 million in proceeds upon exercises of stock options and sales pursuant to our employee stock purchase plan.
Future Financing Transactions—We regularly consider various options to obtain financing and access the capital markets, subject to market conditions, to meet our funding needs. Such capital raising alternatives, in addition to those noted above, may include amendments and extensions of our bank facilities, entry into new bank facilities, transactions with private equity funds or partnerships, additional senior note and equity offerings and securitization transactions. No assurance can be given as to whether any such financing transactions will be completed or as to the timing or terms thereof.
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 net operating losses (“NOLs”). We have distributed an aggregate of approximately $19.8 billion to our common stockholders, including the dividend paid in October 2024, primarily classified as ordinary income that may be treated as qualified REIT dividends under Section 199A of the Code for taxable years beginning before 2026.
During the nine months ended September 30, 2024, we paid $4.94 per share, or $2.3 billion, to our common stockholders of record. In addition, we declared a distribution of $1.62 per share, or $757.0 million, paid on October 25, 2024 to our common stockholders of record at the close of business on October 9, 2024.
The amount, timing and frequency of future distributions will be at the sole discretion of our Board of Directors and will depend on 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 taxable REIT subsidiaries and other factors that our Board of Directors may deem relevant.
We accrue distributions on unvested restricted stock units, which are payable upon vesting. As of September 30, 2024, the amount accrued for distributions payable related to unvested restricted stock units was $20.4 million. During the nine months ended September 30, 2024, we paid $11.0 million of distributions upon the vesting of restricted stock units.
Factors Affecting Sources of Liquidity    
As discussed in the “Liquidity and Capital Resources” section of the 2023 Form 10-K, our liquidity depends 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—Each Bank Loan Agreement contains 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 restrictions include limitations on additional debt, distributions and dividends, guaranties, sales of assets and liens. The Bank Loan Agreements also contain covenants that establish financial tests with which we and our restricted subsidiaries must comply related to total leverage and senior secured leverage, as set forth in the table below. As of September 30, 2024, we were in compliance with each of these covenants.

(2)Assumes no change to Adjusted EBITDA.
(3)Assumes no change to our debt levels.
(4)Effectively, however, additional Senior Secured Debt under this ratio would be limited to the capacity under the Consolidated Total Leverage Ratio.
The Bank Loan Agreements also contain reporting and information covenants that require us to provide financial and operating information to the lenders 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.
Failure to comply with the financial maintenance tests and certain other covenants of the Bank Loan Agreements could not only prevent us from being able to borrow additional funds under the revolving credit facilities, but may also constitute a default, 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 Bank Loan Agreements 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 2015 Securitization and the Trust Securitizations—The indenture and related supplemental indenture governing the American Tower Secured Revenue Notes, Series 2015-2, Class A (the “Series 2015-2 Notes”) issued by GTP Acquisition Partners I, LLC (“GTP Acquisition Partners”) in a private securitization transaction in May 2015 (the “2015 Securitization”) and the loan agreement related to the securitization transactions completed in March 2018 (the “2018 Securitization”) and March 2023 (the “2023 Securitization” and, together with the 2018 Securitization, the “Trust Securitizations”) (collectively, the “Securitization Loan Agreements”) include certain financial ratios and operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, GTP Acquisition Partners and American Tower Asset Sub, LLC and American Tower Asset Sub II, LLC (together, the “AMT Asset Subs”) 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 applicable agreements).
Under the Securitization Loan Agreements, amounts due will be paid from the cash flows generated by the assets securing the Series 2015-2 Notes or the assets securing the nonrecourse loan that secures the Secured Tower Revenue Securities, Series 2018-1, Subclass A (the “Series 2018-1A Securities”), the Secured Tower Revenue Securities, Series 2018-1, Subclass R (the “Series 2018-1R Securities” and, together with the Series 2018-1A Securities, the “2018 Securities”), the Secured Tower Revenue Securities 2023-1, Subclass A (the “Series 2023-1A Securities”), the Secured Tower Revenue Securities, Series 2023-1, Subclass R (the “Series 2023-1R Securities” and, together with the Series 2023-1A Securities, the “2023 Securities”) issued in the Trust Securitizations (the “Loan”), as applicable, which must be deposited into certain reserve accounts, and thereafter distributed, solely pursuant to the terms of the applicable agreement. On a monthly basis, after paying all required amounts under the applicable agreement, subject to the conditions described in the table below, the excess cash flows generated from the operation of these assets are released to GTP Acquisition Partners or the AMT Asset Subs, as applicable, which can then be distributed to us for use. As of September 30, 2024, $81.7 million held in such reserve accounts was classified as restricted cash.
Certain information with respect to the 2015 Securitization and the Trust Securitizations is set forth below. The debt service coverage ratio (“DSCR”) is generally calculated as the ratio of the net cash flow (as defined in the applicable agreement) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Series 2015-2 Notes or the Loan, as applicable, that will be outstanding on the payment date following such date of determination.

(1)Based on the net cash flow of the applicable issuer or borrower as of September 30, 2024 and the expenses payable over the next 12 months on the Series 2015-2 Notes or the Loan, as applicable.
(2)If the DSCR were equal to or below 1.30x (the “Cash Trap DSCR”) for any quarter, 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 under the applicable transaction documents, referred to as excess cash flow, will be deposited into a reserve account (the “Cash Trap Reserve Account”) instead of being released to the applicable issuer or borrower. Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar quarters.
(3)An amortization period commences if the DSCR is equal to or below 1.15x (the “Minimum DSCR”) at the end of any calendar quarter and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters.
(4)No amortization period is triggered if the outstanding principal amount of a series has not been repaid in full on the applicable anticipated repayment date. However, in that event, additional interest will accrue on the unpaid principal balance of the applicable series, and that series will begin to amortize on a monthly basis from excess cash flow.
(5)An amortization period exists if the outstanding principal amount has not been paid in full on the applicable anticipated repayment date and continues to exist until the principal has been repaid in full.

A failure to meet the noted DSCR tests could prevent GTP Acquisition Partners or the AMT Asset Subs from distributing excess cash flow to us, which could affect our ability to fund our capital expenditures, including tower construction and acquisitions, and to meet REIT distribution requirements. During an “amortization period,” all excess cash flow and any amounts then in the applicable Cash Trap Reserve Account would be applied to pay the principal of the Series 2015-2 Notes or the Loan, as applicable, 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 the Series 2015-2 Notes or subclass of the Loan from and after the anticipated repayment date at a per annum rate determined in accordance with the applicable agreement. With respect to the Series 2015-2 Notes, upon the occurrence of, and during, an event of default, the applicable trustee may, in its discretion or at the direction of holders of more than 50% of the aggregate outstanding principal of the Series 2015-2 Notes, declare the Series 2015-2 Notes immediately due and payable, in which case any excess cash flow would need to be used to pay holders of those notes. Furthermore, if GTP Acquisition Partners or the AMT Asset Subs were to default on the Series 2015-2 Notes or the Loan, the applicable trustee may seek to foreclose upon or otherwise convert the ownership of all or any portion of the 3,340 communications sites that secure the Series 2015-2 Notes or the 5,029 broadcast and wireless communications towers and related assets that secure the Loan, respectively, in which case we could lose those sites and their associated revenue.
As discussed above, we use our available liquidity and seek new sources of liquidity to fund capital expenditures, future growth and expansion initiatives, satisfy our distribution requirements and repay or repurchase our debt. 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. Additionally, as further discussed under the caption “Risk Factors” in Item 1A of the 2023 Form 10-K, market volatility and disruption caused by inflation,
59


rising interest rates and supply chain disruptions may impact our ability to raise additional capital through debt financing activities or our ability to repay or refinance maturing liabilities, or impact the terms of any new obligations. 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 and debt service obligations, 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 the 2023 Form 10-K, we derive a substantial portion of our revenues from a small number of customers and, consequently, a failure by a significant customer 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 the 2023 Form 10-K.
Critical Accounting Policies and Estimates
Management’s discussion and analysis of financial condition and results of operations are based upon our consolidated and 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, revenue recognition, rent expense, income taxes and accounting for business combinations and acquisitions of assets, as further discussed in the 2023 Form 10-K. 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 nine months ended September 30, 2024. We have made no material changes to the critical accounting policies described in the 2023 Form 10-K.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of September 30, 2024 consisted of $140.0 million under the 2021 Multicurrency Credit Facility, $1.1 billion under the 2021 Credit Facility and $1.0 billion under the 2021 Term Loan. A 10% increase in current interest rates would result in an additional $10.5 million of interest expense for the nine months ended September 30, 2024.
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 Accumulated other comprehensive loss. We may enter into additional foreign currency financial instruments in anticipation of future transactions to minimize the impact of foreign currency exchange rate fluctuations. For the nine months ended September 30, 2024, 35% of our revenues and 43% of our total operating expenses were denominated in foreign currencies.
As of September 30, 2024, we have incurred intercompany debt that 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 $34.4 million of unrealized losses that would be included in Other income (expense) in our consolidated statements of operations for the nine months ended September 30, 2024. As of September 30, 2024, we have 7.5 billion EUR (approximately $8.4 billion) denominated debt outstanding. An adverse change of 10% in the underlying exchange rates of our outstanding EUR debt would result in $0.9 billion of foreign currency losses that would be included in Other expense in our consolidated statements of operations for the nine months ended September 30, 2024.
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.
