NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions, unless otherwise noted)

1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated and condensed consolidated financial statements have been prepared by American Tower Corporation (together with its subsidiaries, “ATC” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial information included herein is unaudited. However, the Company believes that all adjustments, which are of a normal and recurring nature, considered necessary for a fair presentation of its financial position and results of operations for such periods have been included herein. The consolidated and condensed consolidated financial statements and related notes should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the entire year.

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

As of March 31, 2024, the Company holds (i) a 52% controlling interest in subsidiaries whose holdings consist of the Company’s operations in France, Germany and Spain (such subsidiaries collectively, “ATC Europe”) (Allianz and CDPQ (each as defined in note 11) hold the noncontrolling interests), (ii) a 51% controlling interest in a joint venture whose holdings consist of the Company’s operations in Bangladesh (Confidence Tower Holdings Ltd. (“Confidence Group”) holds the noncontrolling interest) and (iii) a controlling common equity interest of approximately 72% in the Company’s U.S. data center business (Stonepeak (as defined and further discussed in note 11) holds approximately 28% of the outstanding common equity and 100% of the outstanding mandatorily convertible preferred equity). As of March 31, 2024, ATC Europe holds an 87% and an 83% controlling interest in subsidiaries that consist of the Company’s operations in Germany and Spain, respectively (PGGM holds the noncontrolling interests). See note 11 for a discussion of changes to the Company’s noncontrolling interests during the three months ended March 31, 2024 and 2023.

*Pending ATC TIPL Transaction—*On January 4, 2024, the Company, through its subsidiaries, ATC Asia Pacific Pte. Ltd. and ATC Telecom Infrastructure Private Limited (“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 will acquire a 100% ownership interest in ATC TIPL (the “Pending ATC TIPL Transaction”). Subject to certain pre-closing terms, 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 three months ended March 31, 2024, ATC TIPL distributed approximately 9,603 million INR (approximately $115.1 million) to the Company, which will be deducted from the total aggregate consideration received at closing. The Company will retain the full economic benefit associated with the VIL OCDs, the VIL Shares and rights to payments on certain existing customer receivables. The Pending ATC TIPL Transaction is expected to close in the second half of 2024, subject to customary closing conditions, including government and regulatory approval.

Reportable Segments—The Company reports its results in seven segments – U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services, which are discussed further in note 14.

Significant Accounting Policies—The Company’s significant accounting policies are described in note 1 to the Company’s consolidated financial statements included in the 2023 Form 10-K. There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2024, other than those noted below.

Property and Equipment—The Company finalized its review of the estimated useful lives of its tower assets during the three months ended March 31, 2024. The Company now has over 20 years of operating history, and determined that it should modify its current estimates for asset lives based on its historical operating experience. The Company retained an independent consultant to assist the Company in completing this review and analysis. The Company previously depreciated its towers on a straight-line basis over the shorter of the term of the underlying ground lease (including

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions, unless otherwise noted)

renewal options) taking into account residual value or the estimated useful life of the tower, which the Company had historically estimated to be 20 years. The Company determined that the estimated useful life of its tower assets is 30 years, before taking into account residual value. Additionally, certain of the Company’s intangible assets are amortized on a similar basis to its tower assets, as the estimated useful lives of such intangible assets correlate to the useful life of the towers. The Company accounted for the changes in the useful lives as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning on January 1, 2024. On January 1, 2024, the Company began depreciating its towers and related intangible assets on a straight-line basis over the remaining estimated useful life of the tower, taking into account the extended useful life and residual value. The extension of the asset lives (i) 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 and (ii) is expected to result in an estimated $730 million decrease in depreciation and amortization expense for the year ended December 31, 2024.

Asset Retirement Obligations—The Company finalized its review of the estimated settlement dates for its asset retirement obligations during the three months ended March 31, 2024. The Company now has over 20 years of operating history, and determined that it should modify its current estimated settlement dates based on its historical operating experience, management’s intent with respect to the assets, and the assets’ estimated useful lives. Based on its review and analysis, the Company concluded that a revision in the estimated settlement dates for its asset retirement obligations was appropriate. The Company accounted for the change in estimated settlement dates as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning on January 1, 2024. The extension in the estimated settlement dates (i) resulted in a $470 million increase in the asset retirement obligation liability, with an offsetting adjustment made to the related long-lived tangible asset and an $875 million increase in the estimated undiscounted future cash outlay for asset retirement obligations, and (ii) is expected to result in an estimated $75 million decrease in accretion expense for the year ended December 31, 2024.

*Adoption of Highly Inflationary Accounting in Ghana—*The Ghanaian economy was deemed to be highly inflationary and, as a result, the Company adopted highly inflationary accounting as of January 1, 2024 for its subsidiary in Ghana. Under highly inflationary accounting, the functional currency of its subsidiary in Ghana will become the U.S. Dollar. All monetary and non-monetary assets and liabilities will be remeasured at the U.S. Dollar to Ghanaian Cedis exchange rate of 1 to 11.95 as of December 31, 2023. These amounts will become the new basis for those assets and liabilities as of January 1, 2024. Non-monetary assets and liabilities, as well as the corresponding income statement activities such as depreciation, amortization and equity, will continue to be measured at the historical exchange rate on December 31, 2023. Gains and losses on foreign currency arising in connection with the remeasurement of local currency denominated monetary assets and liabilities for foreign operating subsidiaries in economies that are deemed to be highly inflationary are reflected in Other expense in the consolidated statements of operations. This change is not expected to have a material impact on the Company’s financial statements, as Ghana’s assets and revenue are approximately 1% and 1% of consolidated assets and revenue, respectively.

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

Three Months Ended March 31,
20242023
Cash and cash equivalents$2,389.1$1,803.0
Restricted cash127.6122.4
Total cash, cash equivalents and restricted cash$2,516.7$1,925.4

Revenue—The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located, the land underlying its customers’ sites and the space in its data center facilities (the “lease component”) and from the reimbursement of costs incurred by the Company in operating the communications sites and data center facilities and supporting its customers’ equipment as well as other services and contractual rights (the “non-lease component”). Most of the Company’s revenue is derived from leasing arrangements and is accounted for as lease revenue unless the timing and pattern of revenue recognition of the non-lease component differs from the lease component. If the timing and pattern of the non-lease component revenue recognition differs from that of the lease component, the Company separately determines the stand-alone selling prices and pattern of revenue recognition for each performance obligation. Revenue related to distributed antenna system (“DAS”) networks and fiber and other related assets results from agreements with customers that are generally not accounted for as leases.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions, unless otherwise noted)

Non-lease property revenue—Non-lease property revenue consists primarily of revenue generated from DAS networks, fiber and other property related revenue. DAS networks and fiber arrangements generally require that the Company provide the tenant the right to use available capacity on the applicable communications infrastructure. Performance obligations are satisfied over time for the duration of the arrangements. Non-lease property revenue also includes revenue generated from interconnection offerings in the Company’s data center facilities. Interconnection offerings are generally contracted on a month-to-month basis and are cancellable by the Company or the data center customer at any time. Performance obligations are satisfied over time for the duration of the arrangements. Other property related revenue streams, which include site inspections, are not material on either an individual or consolidated basis. There were no material changes in the receivables, contract assets and contract liabilities from contracts with customers for the three months ended March 31, 2024.

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

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

Total revenue$1,340.3$251.1$317.0$191.7$464.1$203.0$2,767.2

Property revenue for the three months ended March 31, 2024 and 2023 includes straight-line revenue of $79.0 million and $112.0 million, respectively.

The Company actively monitors the creditworthiness of its customers. In recognizing customer revenue, the Company assesses the collectibility of both the amounts billed and the portion recognized in advance of billing on a straight-line basis. This assessment takes customer credit risk and business and industry conditions into consideration to ultimately determine the collectibility of the amounts billed. To the extent the amounts, based on management’s estimates, may not be collectible, revenue recognition is deferred until such point as collectibility is determined to be reasonably assured.

During the three months ended March 31, 2023, the Company deferred recognition of revenue of approximately $33.0 million related to a customer in India. During the three months ended March 31, 2024, the Company recognized approximately $29.0 million of this previously deferred revenue.

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.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions, unless otherwise noted)

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.

2. PREPAID AND OTHER CURRENT ASSETS

Prepaid and other current assets consisted of the following:

Other miscellaneous current assets (1)316.6347.6
Prepaid and other current assets$984.6$946.9

(1)Includes the VIL OCDs and the VIL Shares (each as defined and further discussed in note 7).

3. LEASES

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

During the three months ended March 31, 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 March 31, 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.

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 March 31, 2024, the remaining weighted average amortization period of the Company’s lease incentives was 10 years. As of March 31, 2024, Other current assets and Other non-current assets include $35.5 million and $339.4 million, respectively, for lease incentives.

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 March 31, 2024 were as follows:

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 months ended March 31, 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 March 31, 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 three months ended March 31, 2024, other than leases acquired in connection with acquisitions, 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 three months ended March 31, 2024.

(1)As of March 31, 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 March 31, 2024, the remaining weighted average amortization period of the Company’s intangible assets was 20 years. Amortization of intangible assets for the three months ended March 31, 2024 and 2023 was $242.5 million and $369.5 million, respectively. Based on current exchange rates, the Company expects to record amortization expense as follows over the remaining current year and the five subsequent years:

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

Unrealized holding gains and losses for equity securities are recorded in Other income (expense) in the consolidated statements of operations in the current period. During the three months ended March 31, 2024 and 2023, the Company recognized unrealized (losses) gains of $(14.7) million and $1.2 million, respectively, for equity securities held as of March 31, 2024.

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 are (a) to be repaid by VIL with interest or (b) convertible into equity of VIL. If converted and following registration, such equity shall be free to trade in the open market beginning on the one year anniversary of the date of issuance of the VIL OCDs. 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 accrue interest at a rate of 11.2% annually. Interest is payable to ATC TIPL semi-annually, with the first payment received in September 2023.

On March 23, 2024, the Company 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”), which were unregistered as of March 31, 2024. The fair value of the VIL Shares as of March 31, 2024 was $172.7 million. The VIL Shares were registered on April 16, 2024 and the Company completed the sale of VIL Shares on April 29, 2024 for total net proceeds of approximately $216.0 million, as further discussed in note 15.

The VIL OCDs and the VIL Shares are recorded in Prepaid and other current assets in the consolidated balance sheet at fair value. The significant input to the fair value of the VIL OCDs is the lesser of the (i) VIL equity share price underlying the instruments, less a liquidity discount, and (ii) redemption value. The significant input to the fair value of the VIL Shares is the VIL equity share price underlying the shares, less a liquidity discount. Unrealized holding gains and losses for the VIL OCDs are recorded in Other income (expense) in the consolidated statements of operations in the current period.

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 months ended March 31, 2024 or 2023 and there were no significant unobservable inputs used to determine the fair value of long-lived assets during the three months ended March 31, 2024 or 2023.

Fair Value of Financial Instruments—The Company’s financial instruments for which the carrying value reasonably approximates fair value at March 31, 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 March 31, 2024 and December 31, 2023, the carrying value of long-term obligations, including the current portion, was $39.3 billion and $38.9 billion, respectively. As of March 31, 2024, the fair value of long-term obligations, including the current portion, was $36.8 billion, of which $29.4 billion was measured using Level 1 inputs and $7.4 billion was measured using Level 2 inputs. As of December 31, 2023, the fair value of long-term obligations, including the current portion, 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.

(tabular amounts in millions, unless otherwise noted)

The increase in the income tax provision during the three months ended March 31, 2024 was 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.

As of March 31, 2024 and December 31, 2023, the total unrecognized tax benefits that would impact the ETR, if recognized, were approximately $132.1 million and $130.7 million, respectively. The amount of unrecognized tax benefits during the three months ended March 31, 2024 includes (i) additions to the Company’s existing tax positions of $1.0 million and (ii) changes due to foreign currency exchange rate fluctuations of $0.4 million. Unrecognized tax benefits are expected to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this time frame, as described in note 12 to the Company’s consolidated financial statements included in the 2023 Form 10-K. The impact of the amount of these changes to previously recorded uncertain tax positions could range from zero to $14.3 million.

The Company recorded the following penalties and income tax-related interest expense during the three months ended March 31, 2024 and 2023:

Three Months Ended March 31,
20242023
Penalties and income tax-related interest expense$5.5$2.8

As of March 31, 2024 and December 31, 2023, the total amount of accrued income tax related interest and penalties included in the consolidated balance sheets were $67.3 million and $62.8 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 March 31, 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 months ended March 31, 2024 and 2023, the Company recorded the following stock-based compensation expense in selling, general, administrative and development expense:

Three Months Ended March 31,
20242023
Stock-based compensation expense$64.9$65.5

Stock Options—As of March 31, 2024, there was no unrecognized compensation expense related to unvested stock options.

*Restricted Stock Units—*As of March 31, 2024, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $258.1 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 three months ended March 31, 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:

10. EQUITY

Sales of Equity Securities—The Company receives proceeds from sales of its equity securities pursuant to the ESPP and upon exercise of stock options granted under the 2007 Plan. During the three months ended March 31, 2024, the Company received an aggregate of $13.9 million in proceeds upon exercises of stock options.

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

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

During the three months ended March 31, 2024, there were no repurchases under either of the Buyback Programs. As of March 31, 2024, the Company has repurchased a total of 14,451,325 shares of its common stock under the 2011 Buyback for an aggregate of $1.5 billion, including commissions and fees. As of March 31, 2024, the Company has not made any repurchases under the 2017 Buyback.

The Company expects to fund any further repurchases of its common stock through a combination of cash on hand, cash generated by operations and borrowings under its credit facilities. Repurchases under the Buyback Programs are subject to, among other things, the Company having available cash to fund the repurchases.

13. COMMITMENTS AND CONTINGENCIES

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

Verizon Transaction—In March 2015, the Company entered into an agreement with various operating entities of Verizon Communications Inc. (“Verizon”) that currently provides for the lease, sublease or management of approximately 11,200 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.

AT&T Transaction—The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. (“AT&T”), that currently provides for the lease or sublease of approximately 1,800 towers, which commenced between December 2000 and August 2004. Substantially all of the towers are part of the Trust Securitizations. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 27 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the sites subject to the applicable lease or sublease upon its expiration. Each tower is assigned to an annual tranche, ranging from 2013 to 2032, which represents the outside expiration date for the sublease rights to that tower. The purchase price for each site is a fixed amount stated in the lease for that site plus the fair market value of certain alterations made to the related tower by AT&T. As of March 31, 2024, the Company has purchased an aggregate of approximately 600 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. The Company has historically reported these operations on a geographic basis.

Data Centers—The Company’s Data Centers segment relates to data center facilities and related assets that the Company owns and operates in the United States. The Data Centers segment offers different types of leased land and related services from, and requires different resources, skill sets and marketing strategies than the existing property operating segment in the U.S. & Canada.

As of March 31, 2024, the Company’s property operations consisted of the following:

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

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

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

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

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

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

Services

The Company’s Services segment offers tower-related services in the United States, including AZP, 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 months ended March 31, 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.
