**AMERICAN TOWER CORPORATION AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(tabular amounts in millions, unless otherwise noted)**

**1.&nbsp;&nbsp;&nbsp;&nbsp;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. 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, 2025 (the "2025 Form 10-K"). The results of operations for the three months ended March 31, 2026 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, 2026, 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 La Caisse (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 71% in the Company's U.S. data center business (Stonepeak (as defined and further discussed in note 11) holds approximately 29% of the outstanding common equity and 100% of the outstanding mandatorily convertible preferred equity). As of March 31, 2026, 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, 2026 and 2025.

*Significant Accounting Policies*—The Company's significant accounting policies are described in note 1 to the Company's consolidated financial statements included in the 2025 Form 10-K. There have been no material changes to the Company's significant accounting policies during the three months ended March 31, 2026, other than those noted below.

*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,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Cash and cash equivalents | $1608.8 | $2103.7 |
| Restricted cash | 129.1 | 135.5 |
| Total cash, cash equivalents and restricted cash | $1737.9 | $2239.2 |

---

*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.

*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

**AMERICAN TOWER CORPORATION AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(tabular amounts in millions, unless otherwise noted)**

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, 2026.

*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 services, together with program management offerings that support customer deployment needs from project scoping through construction. 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:

---

Property revenue for the three months ended March 31, 2026 and 2025 includes straight-line revenue of $18.9 million and $17.1 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 the uncertainty is resolved.

*Accounting Standards Updates*—In November 2024, the FASB issued guidance which is intended to improve the disclosures about a public business entity's expenses, primarily through additional disclosures about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) included in each relevant expense caption presented on the face of the income statement within continuing operations. The guidance is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In November 2025, the FASB issued guidance which is intended to more closely align hedge accounting with the economics of an entity's risk management activities. The amendments are intended to better reflect those strategies in financial reporting by enabling entities to achieve and maintain hedge accounting for highly effective economic hedges of forecasted transactions. The guidance is effective on a prospective basis for annual periods beginning after December

15, 2026, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

**2.&nbsp;&nbsp;&nbsp;&nbsp;PREPAID AND OTHER CURRENT ASSETS** 

Prepaid and other current assets consisted of the following:

---

| | | |
|:---|:---|:---|
| | **As of** | **As of** |
| | **March 31, 2026** | **December 31, 2025** |

| Other miscellaneous current assets | 93.9 | 99.6 |
| Prepaid and other current assets | $499.6 | $486.3 |

---

**3.&nbsp;&nbsp;&nbsp;&nbsp;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, 2026, the Company made no changes to the methods described in note 4 to its consolidated financial statements included in the 2025 Form 10-K. As of March 31, 2026, 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 March 31, 2026 were as follows:

---

| | |
|:---|:---|
| **Fiscal Year** | **Amount (1) (2)** |
| Remainder of 2026 | $6445.5 |
| 2027 | 8513.5 |
| 2028 | 7120.9 |
| 2029 | 6660.1 |
| 2030 | 5321.4 |
| Thereafter | 16376.0 |
| Total | $50437.4 |

_______________

(1)Balances are translated at the applicable period-end exchange rate, which may impact comparability between periods.&nbsp;&nbsp;&nbsp;&nbsp;

(2)Balances represent contractual amounts owed with no adjustments made for expected collectibility. As of March 31, 2026, balances exclude contractual amounts owed from one of the Company's U.S. customers, DISH Wireless L.L.C., a subsidiary of DISH Network Corporation ("DISH").

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, 2026, the remaining weighted average amortization period of the Company's lease incentives was 9 years. As of March 31, 2026, Other current assets and Other non-current assets include $49.5 million and $349.4 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 2025 Form 10-K. There were no material impairments recorded related to these assets during the three months ended March 31, 2026 and 2025. The Company leases certain land, buildings, equipment and office space under operating leases and land and improvements, towers,

As of March 31, 2026, 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, 2026, there were no material changes in the terms and provisions of the Company's operating leases in which the Company is a lessee. There were no material changes in finance lease assets and liabilities during the three months ended March 31, 2026.

---

_______________

(1)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.

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.

**7.&nbsp;&nbsp;&nbsp;&nbsp;FAIR VALUE MEASUREMENTS** 

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

---

| | |
|:---|:---|
| Level 1 | Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. |
| Level 2 | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. |
| Level 3 | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. |

*Items Measured at Fair Value on a Recurring Basis*—The fair values of the Company's financial assets and liabilities that are required to be measured on a recurring basis at fair value were as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| | **March 31, 2026** | **March 31, 2026** | **March 31, 2026** | **December 31, 2025** | **December 31, 2025** | **December 31, 2025** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Investments in equity securities (1) | $17.5 | $183.8 |  | $15.3 | $161.6 |  |

---

_______________

(1)Investments in equity securities are recorded in Notes receivable and other non-current assets in the consolidated balance sheets at fair value. Unrealized holding gains and losses for equity securities are recorded in Other income (expense) in the consolidated statements of operations in the current period. During three months ended March 31, 2026, the Company recognized unrealized gains of $24.4 million for equity securities held as of March 31, 2026. During three months ended March 31, 2025, the Company recognized unrealized gains of $7.6 million for equity securities held as of March 31, 2025.

*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. The significant unobservable inputs used to determine the fair value of long-lived assets during the three months ended March 31, 2026 or 2025 are consistent with those described in note 10 to the consolidated financial statements included in the 2025 Form 10-K.

There were no other items measured at fair value on a nonrecurring basis during the three months ended March 31, 2026 or 2025.

*Fair Value of Financial Instruments*—The Company's financial instruments for which the carrying value reasonably approximates fair value at March 31, 2026 and December 31, 2025 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, 2026 and December 31, 2025, the carrying value of long-term obligations, including the current portion, was $37.3 billion and $37.2 billion, respectively. As of March 31, 2026, the fair value of long-term obligations, including the current portion, was $35.8 billion, of which $31.9 billion was measured using Level 1 inputs and $3.9 billion was measured using Level 2 inputs. As of December 31, 2025, the fair value of long-term obligations, including the current portion, was $36.1 billion, of which $32.9 billion was measured using Level 1 inputs and $3.2 billion was measured using Level 2 inputs.

*Net Investment Hedge*

*Foreign Currency Debt—*On June 1, 2025, the Company designated approximately 4.7 billion EUR (approximately $5.3 billion at the designation date) of senior unsecured notes as a non-derivative net investment hedge on the Company's net investments in its European subsidiaries, whose functional currency is the EUR, to mitigate against the effect of exchange rate fluctuations on the translation of foreign currency balances to the USD.

The following table presents the contractual amounts of the Company's outstanding instruments:

---

| | | | |
|:---|:---|:---|:---|
| | | **As of** | **As of** |
| |<br>**Designation** | **March 31, 2026** | **December 31, 2025** |
| Foreign currency-denominated debt (1) | Net Investment Hedge | $5372.0 | $5461.6 |

---

_______________

(1)During the three months ended March 31, 2026, the Company recorded $89.6 million of unrealized foreign currency gains related to the EUR denominated debt that was designated as a net investment hedge as a foreign currency translation adjustment in Accumulated other comprehensive loss. As of March 31, 2026, includes 4.7 billion EUR ($5.4 billion) of outstanding EUR denominated debt designated as hedges of a portion the Company's net investment in foreign operations. This debt matures in fiscal years 2026 through 2034.

**8.&nbsp;&nbsp;&nbsp;&nbsp;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.

**(tabular amounts in millions, unless otherwise noted)**

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 increase in the income tax provision during the three months ended March 31, 2026 was primarily attributable to (i) increases in earnings in certain foreign jurisdictions and (ii) increases in unrealized gains from equity securities in the United States, partially offset by the nonrecurrence of taxes related to the sale of the Company's fiber assets in South Africa ("South Africa Fiber") during the three months ended March 31, 2025.

As of March 31, 2026 and December 31, 2025, the total unrecognized tax benefits that would impact the ETR, if recognized, were approximately $131.1 million and $128.6 million, respectively. The amount of unrecognized tax benefits during the three months ended March 31, 2026 includes (i) additions to the Company's existing tax positions of $1.6 million and (ii) additions due to foreign currency exchange rate fluctuations of $0.9 million.

The Company recorded the following penalties and income tax-related interest expense during the three months ended March 31, 2026 and 2025:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Penalties and income tax-related interest expense | $5.9 | $5.5 |

---

As of March 31, 2026 and December 31, 2025, the total amount of accrued income tax related interest and penalties included in the consolidated balance sheets were $93.5 million and $86.8 million, respectively.

**9.&nbsp;&nbsp;&nbsp;&nbsp;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 and Human Capital Committee (the "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, 2026, the Company had the ability to grant stock-based awards with respect to an aggregate of 1.9 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, 2026 and 2025, the Company recorded the following stock-based compensation expense in selling, general, administrative and development expense:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Stock-based compensation expense (1) | $58.4 | $53.4 |

---

_______________

(1)For the three months ended March 31, 2025, includes the reversal of $7.1 million of previously recognized stock-based compensation expense associated with awards forfeited in connection with the departure of the Company's former Executive Vice President and President, APAC due to such role being eliminated.

*Stock Options*—As of March 31, 2026, there was no unrecognized compensation expense related to unvested stock options.

*Restricted Stock Units—*As of March 31, 2026, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $172.9 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). RSUs will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares that actually vest.

*Performance-Based Restricted Stock Units—*During the three months ended March 31, 2026, the Compensation Committee granted an aggregate of 100,692 PSUs (the "2026 PSUs") to its executive officers and established the performance and market metrics for these awards. During the years ended December 31, 2025 and 2024, the Compensation Committee granted an aggregate of 86,911 PSUs (the "2025 PSUs") and 87,550 PSUs (the "2024 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 2026 PSUs, the 2025 PSUs and the 2024 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.

Certain of the 2026 PSUs, the 2025 PSUs and 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 2026 PSUs, the 2025 PSUs and 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 2026 PSUs, the 2025 PSUs and the 2024 PSUs is $211.01, $286.21 and $216.11, respectively.

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

---

| | | | |
|:---|:---|:---|:---|
| | **2026** | **2025** | **2024** |
| Expected term (years) | 2.81 | 2.81 | 2.81 |

**13.&nbsp;&nbsp;&nbsp;&nbsp;COMMITMENTS AND CONTINGENCIES** 

*Litigation*— The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. While the Company's management, after consultation with counsel, currently believes the ultimate outcome of these legal proceedings, individually and in the aggregate, will not have a material adverse impact on its consolidated financial position, results of operations or liquidity, litigation is subject to inherent uncertainties. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on the Company's financial condition and results of operations.

*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 11,100 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 occupied the sites as a tenant for an initial term of ten years and has exercised its first renewal option for a five-year term. Verizon has seven optional successive five-year terms remaining; each such term shall be governed by standard master lease agreement terms established as a part of the transaction.

**(tabular amounts in millions, unless otherwise noted)**

*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 1,600 towers, which commenced between December 2000 and August 2004. Substantially all of the towers are part of the securitization transactions completed in March 2018 and March 2023 (together, the "Trust Securitization"). 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, 2026, the Company has purchased an aggregate of approximately 800 of the subleased towers which are subject to the applicable agreement. The aggregate purchase option price for the remaining towers leased and subleased is $1.2 billion and includes per annum accretion through the applicable expiration of the lease or sublease of a site. For the applicable sites, AT&T has the right to continue to lease space subject to a monthly fee, which shall escalate in accordance with the standard master lease agreement for the remainder of AT&T's tenancy. AT&T shall have the right to renew each 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.

**NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(tabular amounts in millions, unless otherwise noted)**

The accounting policies applied in compiling segment information below are similar to those described in note 1. 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. The Company's definition of segment operating profit aligns with the Company's definition of Adjusted EBITDA. 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.

The Company's chief operating decision maker (the "CODM") is the Company's chief executive officer. The CODM uses segment gross margin and segment operating profit to evaluate the segments' operating performance, in making capital allocation decisions, and in establishing management's compensation. Additionally, the CODM uses these metrics to monitor budget versus actual results. 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, 2026 and 2025 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.

*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, 2025 (the "2025 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 2025 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."

**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 the three months ended March 31, 2026 and includes our U.S. & Canada property, Africa & Asia-Pacific ("APAC") 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.

The 2025 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 2025 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 three months ended March 31, 2026 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 March 31, 2026, we expect to generate over $50 billion of non-cancellable customer lease revenue over future periods, before the impact of straight-line lease accounting.

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 three months ended March 31, 2026, churn was approximately 5% of our tenant billings, primarily driven by churn due to one of our U.S. customers, DISH Wireless L.L.C., a subsidiary of DISH Network Corporation ("DISH") in our U.S. & Canada property segment, as discussed below. Beginning on January 1, 2026, 100% of DISH revenue will be reflected in churn.

*AT&T Mexico Dispute*. We are currently engaged in a legal dispute (the "Arbitration") with one of our customers in Mexico, AT&T Comunicaciones Digitales, S. de R.L. de C.V. and related entities (collectively, "AT&T Mexico"). AT&T Mexico, which represented approximately $300 million of tenant revenue in 2025, is challenging the calculation of the monthly lease amount established under our Master Lease Agreement with AT&T Mexico (the "MLA"), as well as certain other provisions of the MLA, seeking rent abatement both retroactively and prospectively, and had been withholding tower rents since the start of 2025. We incurred approximately $30 million of reserves during the year ended December 31, 2025, and an additional approximately $10 million of reserves during the three months ended March 31, 2026, related to this customer. We expect to record future reserves until the Arbitration is settled. We believe we have meritorious defenses to the claims raised in this Arbitration, are vigorously defending the full enforceability of the MLA and remain confident in the terms and conditions of the MLA. The Arbitration is scheduled for a hearing in August 2026.

On September 23, 2025, we and AT&T Mexico reached an agreement pursuant to which AT&T Mexico will remit payment of the majority of the withheld tower rents and will resume monthly payments of the majority of its owed tower rents. The remainder of the outstanding receivables and the future monthly tower rent amounts not remitted directly to us will be deposited into an irrevocable escrow account, overseen by an independent trustee, to be released in accordance with a final ruling in the Arbitration or by mutual consent of us and AT&T Mexico.

*DISH Dispute*. On September 24, 2025, DISH delivered a notice purporting to be excused from its contractual obligations under our Strategic Collocation Agreement entered into in March 2021 (the "SCA"). DISH has failed to meet its payment obligations, and as of January 2026 is in default under the SCA. We remain confident that DISH has not been excused from its obligations under the SCA, and that the SCA remains in full force and effect. On October 20, 2025, we filed a complaint in the U.S. District Court for the District of Colorado seeking a declaratory judgment that DISH has not been excused from its obligations under the SCA, that the SCA remains in full force and effect, and that DISH remains required to perform all of its obligations under the SCA. DISH represented approximately 2% and 4% of our total annual property revenue and total annual U.S. & Canada property revenue, respectively, for 2025. DISH is reflected in churn for three months ended March 31, 2026. During the three months ended March 31, 2026, we recorded impairment charges related to DISH of $17.5 million.

**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, Adjusted Funds From Operations ("AFFO") attributable to American Tower Corporation common stockholders ("AFFO attributable to American Tower Corporation common stockholders") and Segment gross margin.

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, and including adjustments and distributions for unconsolidated affiliates and noncontrolling interests and adjustments for 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)."

26&nbsp;&nbsp;&nbsp;&nbsp;

------

We define 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.

Adjusted EBITDA, Nareit FFO (common stockholders), AFFO (common stockholders) and Segment gross margin 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), AFFO (common stockholders) or Segment gross margin 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), AFFO (common stockholders) and Segment gross margin 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) Segment gross margin provides valuable insight into the site-level profitability of our assets; (6) 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 (7) 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), AFFO (common stockholders) and Segment gross margin 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 and Segment gross margin to gross margin, the most directly comparable GAAP measures, have been included below.

The change in other operating expense (income) during the three months ended March 31, 2026 was primarily attributable to a decrease in gains on sales or disposals of assets, primarily attributable to the gain on the sale of our fiber assets in South Africa ("South Africa Fiber") of $53.6 million in the prior year period, partially offset by an increase in impairment charges of $18.2 million, primarily related to DISH in the U.S.

| Total other expense | $221.1 | $636.6 | (65)% |

---

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 EUR denominated senior unsecured notes, our intercompany notes and similar unaffiliated balances denominated in a currency other than the subsidiaries' functional currencies.

The decrease in total other expense during the three months ended March 31, 2026 was primarily due to foreign currency gains of $68.1 million in the current period, as compared to foreign currency losses of $345.7 million in the prior-year period.

---

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 three months ended March 31, 2026 and 2025 differs from the federal statutory rate.

As of January 1, 2024, we and our subsidiaries, in principle, became subject to the Organization for Economic Cooperation and Development (the "OECD") Global Anti-Base Erosion Rules (the "Pillar 2 Rules") as promulgated by jurisdictions. The Pillar 2 Rules can potentially lead to additional taxes ("Top-Up Tax") when the effective tax rate (as defined by the Pillar 2 Rules) in a jurisdiction is below 15%. The Pillar 2 Rules, however, do not apply to "Excluded Entities" and certain subsidiaries of Excluded Entities. We believe we qualify as an Excluded Entity as a "Real Estate Investment Vehicle." In the event certain subsidiaries do not qualify as Excluded Entities, available "Safe Harbor" rules could apply that would exempt the entities from any Top-Up Tax. Substantially all of our non-excluded, non-U.S. jurisdictions qualify for one or more of the Safe Harbor rules. The remaining non-U.S. jurisdictions that may not qualify could have immaterial Top-Up Tax. Beginning in fiscal year 2026, the U.S. income of non-excluded U.S. domiciled entities may result in immaterial Top-Up Tax; however, on January 5, 2026, the OECD announced a comprehensive Side-by-Side Safe Harbor that, if enacted, would exempt U.S.-parented multinational companies from certain Top-Up Taxes under the Pillar 2 Rules beginning January 1, 2026. While the Side-by-Side Safe Harbor has yet to be enacted in any jurisdiction in which we operate, there is an expectation the Side-by-Side Safe Harbor may be adopted prior to year end. The amount of Top-Up Tax from our U.S. income is immaterial.

The increase in the income tax provision during the three months ended March 31, 2026 was primarily attributable to (i) increases in earnings in certain foreign jurisdictions and (ii) increases in unrealized gains from equity securities in the United States, partially offset by the nonrecurrence of taxes related to sale of South Africa Fiber during the three months ended March 31, 2025.

_______________

(1)For the three months ended March 31, 2025, includes a gain on the sale of South Africa Fiber of $53.6 million.

(2)Includes distributions to noncontrolling interest holders, distributions related to the outstanding mandatorily convertible preferred equity in connection with our agreements with certain investment vehicles affiliated with Stonepeak Partners LP and adjustments for the impact of noncontrolling interests on Nareit FFO attributable to American Tower Corporation common stockholders.

(3)For the three months ended March 31, 2026, includes adjustments for refunds in Germany of $0.5 million. We believe that these tax adjustments are nonrecurring, and do not believe these are an indication of our operating performance. Accordingly, we believe it is more meaningful to present AFFO attributable to American Tower Corporation common stockholders excluding these amounts.

(4)Includes (gains) losses on foreign currency exchange rate fluctuations of $(68.1) million and $345.7 million, respectively.

(5)Primarily includes acquisition-related costs, integration costs and disposition costs.

(6)Includes adjustments for the impact of noncontrolling interests on other line items, excluding those already adjusted for in Nareit FFO attributable to American Tower Corporation common stockholders.

33&nbsp;&nbsp;&nbsp;&nbsp;

------

The increase in net income for the three months ended March 31, 2026 was primarily due to (i) changes in other income (expense), primarily due to foreign currency exchange rate fluctuations and (ii) an increase in segment operating profit, partially offset by (w) changes in other operating expense (income), which included the gain on the sale of South Africa Fiber during the three months ended March 31, 2025, (x) an increase in depreciation, amortization and accretion expense, (y) an increase in interest expense and (z) an increase in the income tax provision.

The increase in Adjusted EBITDA for the three months ended March 31, 2026 was primarily attributable to an increase in our gross margin, partially offset by an increase in SG&A, excluding the impact of stock-based compensation expense of $14.9 million.

The increase in AFFO attributable to American Tower Corporation common stockholders for the three months ended March 31, 2026 was primarily attributable to an increase in our operating profit, excluding the impact of straight-line accounting, partially offset by (i) increases in cash paid for interest and cash paid for income taxes, (ii) an increase in distributions and adjustments for noncontrolling interests, including distributions to noncontrolling interest holders in our Data Centers segment, and (iii) an increase in capital improvement capital expenditures.

*Segment Gross Margin Reconciliations*

Gross margin is defined as revenue less costs of operations inclusive of real estate related depreciation, amortization and accretion. Segment gross margin excludes depreciation, amortization and accretion.

**Liquidity and Capital Resources** 

The information in this section updates as of March 31, 2026 the "Liquidity and Capital Resources" section of the 2025 Form 10-K and should be read in conjunction with that report.

***Overview***

During the three months ended March 31, 2026, our significant financing transactions included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Redemption of our 4.400% senior unsecured notes due 2026 (the "4.400%" Notes") upon their maturity.

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 March 31, 2026** |
| Available under the 2021 Multicurrency Credit Facility | $5485.0 |
| Available under the 2021 Credit Facility | 3400.0 |
| Letters of credit | (46.5) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total available under credit facilities, net | $8838.5 |
| Cash and cash equivalents | 1608.8 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total liquidity | $10447.3 |

---

Subsequent to March 31, 2026, we made additional net borrowings of $530.0 million under the 2021 Credit Facility and net borrowings of $740.0 million under the 2021 Multicurrency Credit Facility (each as defined below).

Summary cash flow information is set forth below (in millions):

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Net cash provided by (used for): |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating activities | $1400.6 | $1295.0 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Investing activities | (473.7) | (350.1) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Financing activities | (831.0) | (843.8) |
| Net effect of changes in foreign currency exchange rates on cash and cash equivalents, and restricted cash | 36.8 | 29.9 |
| Net increase in cash and cash equivalents, and restricted cash | $132.7 | $131.0 |

---

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 March 31, 2026, we had total outstanding indebtedness of $37.5 billion, with a current portion of $6.1 billion. During the three months ended March 31, 2026, we generated sufficient cash flow from operations, together with borrowings under our credit facilities, proceeds from our debt issuances 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, 2026, 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.

We utilize notional cash pooling arrangements with financial institutions for cash management purposes. These arrangements allow for cash withdrawals based upon aggregate cash balances on deposit at the same financial institution.

***Material Cash Requirements***— There were no material changes to the Material Cash Requirements section of the 2025 Form 10-K.

35&nbsp;&nbsp;&nbsp;&nbsp;

------

As of March 31, 2026, we had $1.9 billion of cash and cash equivalents held by our foreign subsidiaries. As of March 31, 2026, we had $189.1 million of cash and cash equivalents held by our joint ventures, of which $124.2 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 three months ended March 31, 2026 was primarily attributable to an increase in our operating profit, including the impact of straight-line accounting, and a decrease in cash required for working capital, primarily as a result of changes in accounts receivable, partially offset by increases in cash paid for interest and cash paid for taxes.

***Cash Flows from Investing Activities***

Our significant investing activities during the three months ended March 31, 2026 are highlighted below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We spent $19.2 million for acquisitions,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We spent $459.9 million for capital expenditures, as follows (in millions):

---

| | |
|:---|:---|
| Discretionary capital projects (1) | $295.2 |
| Ground lease purchases (2) | 40.0 |
| Capital improvements and corporate expenditures (3) | 48.3 |
| Redevelopment | 64.7 |
| Start-up capital projects | 11.7 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total capital expenditures | $459.9 |

---

_______________

(1)Includes the construction of 326 communications sites globally and approximately $211.4 million of spend related to data center assets.

(2)Includes $9.6 million of perpetual land easement payments reported in Deferred financing costs and other financing activities in the cash flows from financing activities in our condensed consolidated statements of cash flows.

(3)Includes $0.8 million of finance lease payments reported in Repayments of notes payable, credit facilities, senior notes, secured debt and finance leases in the cash flows from financing activities in our condensed consolidated statements of cash flows.

We plan to continue to allocate our available capital, after satisfying our distribution requirements, among investment alternatives that meet our return on investment criteria, while maintaining our commitment to our long-term financial policies. Accordingly, we expect to continue to deploy capital through our annual capital expenditure program, including land purchases and new site and data center facility construction, and through acquisitions. We also regularly review our portfolios as to capital expenditures required to upgrade our infrastructure to our structural standards or address capacity, structural or permitting issues.

We expect that our 2026 total capital expenditures will be as follows (in millions):

---

| | | | |
|:---|:---|:---|:---|
| Discretionary capital projects (1) | $1050 | to | $1080 |
| Ground lease purchases | 200 | to | 220 |
| Capital improvements and corporate expenditures | 180 | to | 190 |
| Redevelopment | 335 | to | 365 |
| Start-up capital projects | 35 | to | 55 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total capital expenditures | $1800 | to | $1910 |

---

_______________

(1)Includes the construction of approximately 1,700 to 2,300 communications sites globally and approximately $695 million of anticipated spend related to data center assets.

*Repayments of Senior Notes*

*Repayment of 4.400% Senior Notes*—On February 13, 2026, we repaid $500.0 million aggregate principal amount of the 4.400% Notes upon their maturity. The 4.400% Notes were repaid using borrowings under the 2021 Credit Facility and cash on hand. Upon completion of the repayment, none of the 4.400% Notes remained outstanding.

*Repayment of 1.600% Senior Notes—*On April 14, 2026, we repaid $700.0 million aggregate principal amount of our 1.600% senior unsecured notes due 2026 (the "1.600% Notes") upon their maturity. The 1.600% Notes were repaid using borrowings under the 2021 Credit Facility and cash on hand. Upon completion of the repayment, none of the 1.600% Notes remained outstanding.

*Bank Facilities*

*2021 Multicurrency Credit Facility—*During the three months ended March 31, 2026, we borrowed an aggregate of $860.0 million and repaid an aggregate of $725.0 million of revolving 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 used the borrowings for general corporate purposes. We currently have $16.7 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 three months ended March 31, 2026, we borrowed an aggregate of $600.0 million 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 4.400% Notes, and for general corporate purposes. We currently have $29.8 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.

As of March 31, 2026, the key terms under the 2021 Multicurrency Credit Facility, the 2021 Credit Facility and the $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) Secured Overnight Financing Rate ("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 0.100%.

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 the financial and operating covenants of the loan agreements 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.

*Stock Repurchase Program*—In December 2017, our Board of Directors approved a stock repurchase program, pursuant to which we are authorized to repurchase up to $2.0 billion of our common stock (the "Buyback Program").

During the three months ended March 31, 2026, we repurchased 1,053,335 shares of our common stock for an aggregate of $183.7 million, including commissions and fees. Subsequent to March 31, 2026, through April 21, 2026, we repurchased 111,043 shares of our common stock for an aggregate of approximately $19.2 million, including commissions and fees.

We expect to continue managing the pacing of the remaining approximately $1.5 billion under the Buyback Program 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 Program 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 three months ended March 31, 2026, we received an aggregate of $12.5 million in proceeds upon exercises of stock options.

*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 $24.6 billion to our common stockholders, including the dividend paid in April 2026, primarily classified as ordinary income that may be treated as qualified REIT dividends under Section 199A of the Code.

During the three months ended March 31, 2026, we paid $1.70 per share, or $792.9 million, to our common stockholders of record. In addition, we declared a distribution of $1.79 per share, or $833.9 million, paid on April 28, 2026 to our common stockholders of record at the close of business on April 14, 2026.

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

38&nbsp;&nbsp;&nbsp;&nbsp;

------

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 March 31, 2026, the amount accrued for distributions payable related to unvested restricted stock units was $9.5 million. During the three months ended March 31, 2026, we paid $13.7 million of distributions upon the vesting of restricted stock units.

***Factors Affecting Sources of Liquidity***&nbsp;&nbsp;&nbsp;&nbsp;

As discussed in the "Liquidity and Capital Resources" section of the 2025 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 March 31, 2026, we were in compliance with each of these covenants.

---

| | | | |
|:---|:---|:---|:---|
| | | **Compliance Tests For The 12 Months Ended <br>March 31, 2026<br>($ in billions)** | **Compliance Tests For The 12 Months Ended <br>March 31, 2026<br>($ in billions)** |
| |<br>**Ratio (1)** | **Additional Debt Capacity Under Covenants (2)** | **Capacity for Adjusted EBITDA Decrease Under Covenants (3)** |
| **Consolidated Total Leverage Ratio** | Total Debt to Adjusted EBITDA <br>≤ 6.00:1.00 | ~ 6.0 | ~ 1.0 |
| **Consolidated Senior Secured Leverage Ratio** | Senior Secured Debt to Adjusted EBITDA <br>≤ 3.00:1.00 | ~ 20.2 (4) | ~ 6.7 (4) |

---

_______________

(1)Each component of the ratio as defined in the applicable loan agreement.

(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 under these credit facilities, which could result in, among other things, the amounts outstanding, including all accrued interest and unpaid fees, becoming immediately due and payable. If this were to occur, we may not have sufficient cash on hand to repay such indebtedness. The key factors affecting our ability to comply with the debt covenants described above are our financial performance relative to the financial maintenance tests defined in the 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 Trust Securitization—*The indenture and related supplemental indenture governing 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 Securitization") (the "Securitization Loan Agreements") include certain financial ratios and operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, American Tower Asset Sub, LLC and American Tower Asset Sub II, LLC (together, the "AMT Asset Subs") are prohibited from incurring other

39&nbsp;&nbsp;&nbsp;&nbsp;

------

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 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 Securitization (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 the AMT Asset Subs, which can then be distributed to us for use. As of March 31, 2026, $68.2 million held in such reserve accounts was classified as restricted cash.

Certain information with respect to the Trust Securitization 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 Loan that will be outstanding on the payment date following such date of determination.

---

_____________

(1)Based on the net cash flow of the issuer or borrower as of March 31, 2026 and the expenses payable over the next 12 months on the Loan.

(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)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 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 Loan 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 Loan from and after the anticipated repayment date at a per annum rate determined in accordance with the applicable agreement. Furthermore, if the AMT Asset Subs were to default on the Loan, the trustee may seek to foreclose upon or otherwise convert the ownership of all or any portion of the 5,021 broadcast and wireless communications towers and related assets that secure the Loan, in which case we could lose those sites and their associated revenue.

40&nbsp;&nbsp;&nbsp;&nbsp;

------

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 2025 Form 10-K, market volatility and disruption caused by inflation, high 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 2025 Form 10-K, we derive a substantial portion of our current and projected future revenue 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 2025 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 accounting and impairment of long-lived assets, revenue recognition, rent expense and income taxes, as further discussed in the 2025 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 three months ended March 31, 2026. We have made no material changes to the critical accounting policies described in the 2025 Form 10-K.

**Accounting Standards Update**

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

| **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 March 31, 2026 consisted of $515.0 million under the 2021 Multicurrency Credit Facility, $600.0 million under the 2021 Credit Facility and $1.0 billion under the 2021 Term Loan, $3.6 million of debt entered into by our Data Centers business in connection with an acquisition of a multi-tenant data facility in Denver, Colorado, which is denominated in U.S. Dollars and is payable in monthly installments through March 31, 2028, and $1.2 million in borrowings under our unsecured term loan in Bangladesh, which is denominated in Bangladeshi Taka. A 10% increase in current interest rates would result in an additional $2.5 million of interest expense for the three months ended March 31, 2026.

***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 three months ended March 31, 2026, 34% of our revenues and 42% of our total operating expenses were denominated in foreign currencies.

As of March 31, 2026, 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 $14.8 million of unrealized losses that would be included in Other income (expense) in our consolidated statements of operations for the three months ended March 31, 2026. As of March 31, 2026, we have 7.5 billion EUR (approximately $8.7 billion) denominated debt outstanding, of which approximately 4.7 billion EUR (approximately $5.4 billion) is designated as a non-derivative net investment hedge. An adverse change of 10% in the underlying exchange rates of our outstanding EUR debt not designated as a non-derivative net investment hedge would result in $0.4 billion of foreign currency losses that would be included in Other expense in our consolidated statements of operations for the three months ended March 31, 2026.

**Disclosure Controls and Procedures**

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

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Quarterly Report. Based on this evaluation, our principal executive officer and principal financial officer concluded that these disclosure controls and procedures were effective as of March 31, 2026 and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

**Changes in Internal Control over Financial Reporting**

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

| **ITEM 1.** | **LEGAL PROCEEDINGS** |

---

We periodically become involved in various claims and lawsuits that are incidental to our business. While our management, after consultation with counsel, currently believes the ultimate outcome of these legal proceedings, individually and in the aggregate, will not have a material adverse impact on our consolidated financial position, results of operations or liquidity, litigation is subject to inherent uncertainties. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on our financial condition and results of operations.

*AT&T Mexico Dispute*

We are currently engaged in an Arbitration with AT&T Mexico. AT&T Mexico, which represented approximately $300 million of tenant revenue in 2025, is challenging the calculation of the monthly lease amount established under the MLA, as well as certain other provisions of the MLA, seeking rent abatement both retroactively and prospectively, and had been withholding tower rents since the start of 2025. We incurred approximately $30 million of reserves during the year ended December 31, 2025 related to this customer. We expect to record future reserves until the Arbitration is settled. We believe we have meritorious defenses to the claims raised in this Arbitration, are vigorously defending the full enforceability of the MLA and remain confident in the terms and conditions of the MLA. The Arbitration is scheduled for a hearing in August 2026.

On September 23, 2025, we and AT&T Mexico reached an agreement pursuant to which AT&T Mexico will remit payment of the majority of the withheld tower rents and will resume monthly payments of the majority of its owed tower rents. The remainder of the outstanding receivables and the future monthly tower rent amounts not remitted directly to us will be deposited into an irrevocable escrow account, overseen by an independent trustee, to be released in accordance with a final ruling in the Arbitration or by mutual consent of us and AT&T Mexico.

*DISH Dispute*

On September 24, 2025, DISH delivered a notice purporting to be excused from its contractual obligations under the SCA. DISH has failed to meet its payment obligations, and as of January 2026, is in default under the SCA. We remain confident that DISH has not been excused from its obligations under the SCA, and that the SCA remains in full force and effect. On October 20, 2025, we filed a complaint in the U.S. District Court for the District of Colorado seeking a declaratory judgment that DISH has not been excused from its obligations under the SCA, that the SCA remains in full force and effect, and that DISH remains required to perform all of its obligations under the SCA. DISH represented approximately 2% and 4% of our total annual property revenue and total annual U.S. & Canada property revenue, respectively, for 2025.

(2)Average price paid per share is a weighted average calculation using the aggregate price, excluding commissions and fees.

(3)Remaining under the Buyback Program.

Subsequent to March 31, 2026, through April 21, 2026, we repurchased 111,043 shares of our common stock for an aggregate of approximately $19.2 million, including commissions and fees, under the Buyback Program.

Through April 21, 2026, we have repurchased a total of 3,105,690 shares of our common stock under the Buyback Program for an aggregate of $550.0 million, including commissions and fees. We expect to continue to manage the pacing of the remaining $1.5 billion under the Buyback Program 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. Purchases under the Buyback Program are subject to our having available cash to fund repurchases.

Under the Buyback Program, our management is authorized to purchase shares from time to time through open market purchases or in privately negotiated transactions not to exceed market prices and subject to market conditions and other factors. With respect to open market purchases, we may use plans adopted in accordance with Rule 10b5-1 under the Exchange Act in accordance with securities laws and other legal requirements, which allows us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. These programs may be discontinued at any time.
