Boston, Massachusetts – February 25, 2025: American Tower Corporation (NYSE: AMT) today reported financial results for the quarter and full year ended December 31, 2024.

Steven Vondran, American Tower’s Chief Executive Officer, stated, “We posted another year of solid results at American Tower, delivering AFFO per Share growth supportive of our long-term target, while demonstrating effective execution of the strategic priorities I laid out a year ago. Our initial expectations for accelerating activity over the course of the year were validated, highlighted by mid-band deployments in the U.S. and Europe, 4G densification and early 5G upgrades in emerging markets, and another exceptional year of leasing at CoreSite. The contribution to the margin from these solid demand trends was further complemented by prudent cost controls and the successful execution of our globalization initiatives, driving added efficiency to the already attractive operating leverage inherent to our business.

While the macroeconomic environment remains challenging, demand for connectivity across our global platform continues unabated. The strategic steps we’ve taken to enhance the quality of our earnings through portfolio management, disciplined capital allocation and balance sheet strength, has us well positioned to navigate volatility and uncertainty, while meeting the critical needs of our customers. Taken altogether, our business today is better positioned to deliver durable, sustained growth and returns for our shareholders over the long-term.”

CONSOLIDATED OPERATING RESULTS OVERVIEW(1)(2)

American Tower generated the following operating results for the quarter and full year ended December 31, 2024 (all comparative information is presented against the quarter and full year ended December 31, 2023).

_______________

(1)On September 12, 2024, American Tower Corporation (the “Company” or “American Tower”) completed the sale of 100% of the equity interests in its operations in India (“ATC TIPL” or “ATC India”) to Data Infrastructure Trust, an Infrastructure Investment Trust sponsored by an affiliate of Brookfield Asset Management (the “ATC TIPL Transaction”). The ATC TIPL Transaction qualified for presentation as discontinued operations. Prior to the divestiture and classification as discontinued operations, ATC TIPL’s operating results were included within the Asia-Pacific property segment. Accordingly, the operating results of ATC TIPL are reported as discontinued operations for all periods presented. Please refer to the footnotes and definitions in this release regarding treatment of discontinued operations.

(2)Results for total revenue, total property revenue, total Tenant Billings Growth, Organic Tenant Billings Growth, Property Gross Margin, Adjusted EBITDA, AFFO attributable to AMT common stockholders, as adjusted, and AFFO attributable to AMT common stockholders per Share, as adjusted, exclude the impacts associated with discontinued operations related to the ATC TIPL Transaction. Net income, Net income attributable to AMT common stockholders, Net income attributable to AMT common stockholders per diluted share, Nareit Funds From Operations (FFO) attributable to AMT common stockholders, AFFO attributable to AMT common stockholders, AFFO attributable to AMT common stockholders per Share, Cash provided by operating activities, total cash capital expenditures and Free Cash Flow include the impacts associated with discontinued operations related to the ATC TIPL Transaction.

(3)Q4 2024 and FY 2024 growth rates positively impacted by the Company’s extension of the estimated useful lives of its tower assets and the estimated settlement dates for its asset retirement obligations, which the Company estimates resulted in a decrease of approximately $730 million in depreciation and amortization expense and a decrease of approximately $75 million in accretion expense for the twelve months ended December 31, 2024, as compared to the twelve months ended December 31, 2023. Such decreases were relatively evenly distributed by quarter throughout 2024.

(4)Q4 2024 and FY 2024 growth rates impacted by foreign currency gains of approximately $539.7 million and $308.3 million, respectively, in the current periods as compared to foreign currency losses of approximately $(377.7) million and $(330.6) million, respectively, in the prior-year periods.

(5)FY 2024 growth rates were impacted by a loss on the sale of ATC TIPL of $1.2 billion in the current-year period, which primarily included the reclassification of the Company’s cumulative translation adjustment in India upon exiting the market of $1.1 billion. The loss on sale of ATC TIPL is included in Loss from discontinued operations, net of taxes in the consolidated statements of operations. Q4 and FY 2024 growth rates were also impacted by impairment charges, including goodwill impairments, of $205.3 and $604.4 million recognized in the prior-year periods, respectively.

(6)Represents AFFO attributable to AMT common stockholders from continuing operations adjusted for a full period of interest expense savings associated with the use of approximately $2.0 billion of proceeds from the ATC TIPL Transaction to pay down existing indebtedness under the 2021 Multicurrency Credit Facility (as defined below), at the applicable historical borrowing cost for the respective period. No additional adjustments are required related to the repayment of approximately $120 million under the Company’s unsecured term loan in India, as amended in January 2024 (the “India Term Loan”), as the historical interest expense associated with the India Term Loan is already considered as part of AFFO attributable to AMT common stockholders from discontinued operations when deriving AFFO attributable to AMT common stockholders from continued operations.

(7)Q4 2024 and FY 2024 cash capital expenditures include $9.5 million and $37.4 million, respectively, of finance lease and perpetual land easement payments reported in cash flows from financing activities in the condensed consolidated statements of cash flows.

Liquidity and Financing Activities – As of December 31, 2024, the Company had approximately $12.0 billion of total liquidity, consisting of approximately $2.0 billion in cash and cash equivalents plus the ability to borrow an aggregate of approximately $10.0 billion under its revolving credit facilities, net of any outstanding letters of credit.

On November 21, 2024, the Company issued an aggregate of $1.2 billion in senior unsecured notes. The net proceeds of the offering were used to repay existing indebtedness under its $6.0 billion senior unsecured multicurrency revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Multicurrency Credit Facility”), and its $4.0 billion senior unsecured revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Credit Facility”).

On January 28, 2025, the Company amended the 2021 Multicurrency Credit Facility, the 2021 Credit Facility and its $1.0 billion term loan, as amended and restated in December 2021, as further amended (collectively, the “Loans”), to, among other things, extend the maturity dates under the Loans, and to update the Applicable Margins (as defined in the loan agreements) thereunder.

The following full year 2025 estimates are based on a number of assumptions that management believes to be reasonable and reflect the Company’s expectations as of February 25, 2025. Actual results may differ materially from these estimates as a result of various factors, and the Company refers you to the cautionary language regarding “forward-looking statements” included in this press release when considering this information.

The Company’s outlook is based on the following average foreign currency exchange rates to 1.00 U.S. Dollar for February 25, 2025 through December 31, 2025: (a) 1,202 Argentinean Pesos; (b) 124.10 Bangladeshi Taka; (c) 5.90 Brazilian Reais; (d) 1.44 Canadian Dollars; (e) 1,000 Chilean Pesos; (f) 4,410 Colombian Pesos; (g) 0.97 Euros; (h) 15.50 Ghanaian Cedis; (i) 131 Kenyan Shillings; (j) 20.90 Mexican Pesos; (k) 1,620 Nigerian Naira; (l) 7,900 Paraguayan Guarani; (m) 3.75 Peruvian Soles; (n) 59.60 Philippine Pesos; (o) 18.75 South African Rand; (p) 3,720 Ugandan Shillings; and (q) 630 West African CFA Francs.

The Company’s outlook reflects estimated negative impacts of foreign currency exchange rate fluctuations to total property revenue, Adjusted EBITDA and AFFO attributable to AMT common stockholders of approximately $229 million, $152 million and $126 million, respectively, relative to the Company’s 2024 results. The impact of foreign currency exchange rate fluctuations on net income metrics is not provided, as the impact on all components of the net income measure cannot be calculated without unreasonable effort.

The Company’s 2024 results, for the purposes of the growth rates described below, are presented on a continuing operations basis, with the exception of Net Income, Net Income attributable to AMT common stockholders, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share.

In addition to the results prepared in accordance with generally accepted accounting principles in the United States (GAAP) provided throughout this press release, the Company has presented the following Non-GAAP and Defined Financial Measures: Segment Gross Margin, Segment Operating Profit, Segment Operating Profit Margin, Adjusted EBITDA, Adjusted EBITDA Margin, Nareit Funds From Operations (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, as adjusted, AFFO attributable to American Tower Corporation common stockholders per Share, AFFO attributable to American Tower Corporation common stockholders per Share, as adjusted, Free Cash Flow, Net Debt and Net Leverage Ratio. In addition, the Company presents: Tenant Billings, Tenant Billings Growth, Organic Tenant Billings Growth and New Site Tenant Billings Growth.

These measures are not intended to replace financial performance measures determined in accordance with GAAP. Rather, they are presented as additional information because management believes they are useful indicators of the current financial performance of the Company's core businesses and are commonly used across its industry peer group. As outlined in detail below, the Company believes that these measures can assist in comparing company performance on a consistent basis irrespective of depreciation and amortization or capital structure, while also providing valuable incremental insight into the underlying operating trends of its business.

Depreciation and amortization can vary significantly among companies depending on accounting methods, particularly where acquisitions or non-operating factors, including historical cost basis, are involved. The Company's Non-GAAP and Defined Financial Measures may not be comparable to similarly titled measures used by other companies.

In addition to reporting total revenue, the Company believes that providing transparency around the components of its revenue provides investors with insight into the indicators of the underlying demand for, and operating performance of, its real estate portfolio. Accordingly, the Company has provided disclosure of the following revenue components: (i) Tenant Billings, (ii) New Site Tenant Billings; (iii) Organic Tenant Billings; (iv) International pass-through revenue; (v) Straight-line revenue; (vi) Pre-paid amortization revenue; (vii) Foreign currency exchange impact; and (viii) Other revenue.

Tenant Billings: The majority of the Company’s revenue is generated from non-cancellable, long-term tenant leases. Revenue from Tenant Billings reflects several key aspects of the Company’s real estate business: (i) “colocations/amendments” reflects new tenant leases for space on existing sites and amendments to existing leases to add additional tenant equipment; (ii) “escalations” reflects contractual increases in billing rates, which are typically tied to fixed percentages or a variable percentage based on a consumer price index; (iii) “cancellations” reflects the impact of tenant lease terminations or non-renewals or, in limited circumstances, when the lease rates on existing leases are reduced; and (iv) “new sites” reflects the impact of new property construction and acquisitions.

New Site Tenant Billings: Day-one Tenant Billings associated with sites that have been built or acquired since the beginning of the prior-year period. Incremental colocations/amendments, escalations or cancellations that occur on these sites after the date of their addition to our portfolio are not included in New Site Tenant Billings. In certain cases, this could also include the net impact of certain divestitures. The Company believes providing New Site Tenant Billings enhances an investor’s ability to analyze the Company’s existing real estate portfolio growth as well as its development program growth, as the Company’s construction and acquisition activities can drive variability in growth rates from period to period.

Organic Tenant Billings: Tenant Billings on sites that the Company has owned since the beginning of the prior-year period, as well as Tenant Billings activity on new sites that occurred after the date of their addition to the Company’s portfolio.

International pass-through revenue: A portion of the Company’s pass-through revenue is based on power and fuel expense reimbursements and therefore subject to fluctuations in fuel prices. As a result, revenue growth rates may fluctuate depending on the market price for fuel in any given period, which is not representative of the Company’s real estate business and its economic exposure to power and fuel costs. Furthermore, this expense reimbursement mitigates the economic impact associated with fluctuations in operating expenses, such as power and fuel costs and land rents in certain of the Company’s markets. As a result, the Company believes that it is appropriate to provide insight into the impact of pass-through revenue on certain revenue growth rates.

Straight-line revenue: Under GAAP, the Company recognizes revenue on a straight-line basis over the term of the contract for certain of its tenant leases. Due to the Company’s significant base of non-cancellable, long-term tenant leases, this can result in significant fluctuations in growth rates upon tenant lease signings and renewals (typically increases), when amounts billed or received upfront upon these events are initially deferred. These signings and renewals are only a portion of the Company’s underlying business growth and can distort the underlying performance of our Tenant Billings Growth. As a result, the Company believes that it is appropriate to provide insight into the impact of straight-line revenue on certain growth rates in revenue and select other measures.

Pre-paid amortization revenue: The Company recovers a portion of the costs it incurs for the redevelopment and development of its properties from its tenants. These upfront payments are then amortized over the initial term of the corresponding tenant lease. Given this amortization is not necessarily directly representative of underlying leasing activity on its real estate portfolio (i.e. does not have a renewal option or escalation as our tenant leases do), the Company believes that it is appropriate to provide insight into the impact of pre-paid amortization revenue on certain revenue growth rates to provide transparency into the underlying performance of our real estate business.

Foreign currency exchange impact: The majority of the Company’s international revenue and operating expenses are denominated in each country’s local currency. As a result, foreign currency fluctuations may distort the underlying performance of our real estate business from period to period, depending on the movement of foreign currency exchange rates versus the U.S. Dollar. The Company believes it is appropriate to quantify the impact of foreign currency exchange rate fluctuations on its reported growth to provide transparency into the underlying performance of its real estate business.

Other revenue: Other revenue represents revenue not captured by the above listed items and can include items such as customer settlements, fiber solutions revenue and data centers revenue.

Adjusted EBITDA: 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. The Company believes this measure provides valuable insight into the profitability of its operations while at the same time taking into account the central overhead expenses required to manage its global operations. In addition, it is a widely used performance measure across the telecommunications real estate sector.

Adjusted EBITDA Margin: The percentage that results from dividing Adjusted EBITDA by total revenue.

Adjusted Funds From Operations (AFFO) attributable to American Tower Corporation common stockholders: Nareit FFO attributable to American Tower Corporation 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. The Company believes this measure provides valuable insight into the operating performance of its assets by further adjusting the Nareit AFFO attributable to American Tower Corporation common stockholders metric to exclude the factors outlined above, which if unadjusted, may otherwise cause material fluctuations in Nareit FFO attributable to American Tower Corporation common stockholders growth from period to period that would not be representative of the underlying performance of the Company’s property assets in those periods. In addition, it is a widely used performance measure across the telecommunications real estate sector. The Company believes providing this metric, excluding the impacts of noncontrolling interests, enhances transparency, given the minority interests in its Europe business and its U.S. data center business.

AFFO attributable to American Tower Corporation common stockholders, as adjusted: Represents AFFO attributable to AMT common stockholders from continuing operations adjusted for a full period of interest expense savings associated with the use of approximately $2.0 billion of proceeds from the ATC TIPL Transaction to pay down existing indebtedness under the 2021 Multicurrency Credit Facility, at the applicable historical borrowing cost for the respective period. No additional adjustments are required related to the repayment of approximately $120 million under the India Term Loan, as the historical interest expense associated with the India Term Loan is already considered as part of AFFO attributable to AMT common stockholders from discontinued operations when deriving AFFO attributable to AMT common stockholders from continued operations.

AFFO attributable to American Tower Corporation common stockholders per Share, as adjusted: AFFO attributable to American Tower Corporation common stockholders, as adjusted, divided by the diluted weighted average common shares outstanding.

AFFO attributable to American Tower Corporation common stockholders per Share: AFFO attributable to American Tower Corporation common stockholders divided by the diluted weighted average common shares outstanding.

Free Cash Flow: Cash provided by operating activities less total cash capital expenditures, including the impacts associated with discontinued operations and payments on finance leases and perpetual land easements. The Company believes that Free Cash Flow is useful to investors as the basis for comparing our performance and coverage ratios with other companies in its industry, although this measure of Free Cash Flow may not be directly comparable to similar measures used by other companies.

Nareit Funds From Operations (FFO), as defined by the National Association of Real Estate Investment Trusts (Nareit), attributable to American Tower Corporation common stockholders: Net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges, real estate related depreciation, amortization and accretion including adjustments and distributions for unconsolidated affiliates and noncontrolling interests and discontinued operations. The Company believes this measure provides valuable insight into the operating performance of its property assets by excluding the charges described above, particularly depreciation expenses, given the high initial, up-front capital intensity of the Company’s operating model.

In addition, it is a widely used performance measure across the telecommunications real estate sector.

Net Debt: Total long-term debt, including current portion and for periods beginning in the first quarter of 2019, finance lease liabilities, less cash and cash equivalents.

Net Leverage Ratio: Net debt (total long-term debt, including current portion, and for periods beginning in the first quarter of 2019, finance lease liabilities, less cash and cash equivalents) divided by the quarter’s annualized Adjusted EBITDA (the quarter’s Adjusted EBITDA multiplied by four). The Company believes that including this calculation is important for investors and analysts given it is a critical component underlying its credit agency ratings.

New Site Tenant Billings Growth: The portion of Tenant Billings Growth attributable to New Site Tenant Billings. The Company believes this measure provides valuable insight into the growth attributable to Tenant Billings from recently acquired or constructed properties.

Organic Tenant Billings Growth: The portion of Tenant Billings Growth attributable to Organic Tenant Billings. The Company believes that organic growth is a useful measure of its ability to add tenancy and incremental revenue to its assets for the reported period, which enables investors and analysts to gain additional insight into the relative attractiveness, and therefore the value, of the Company’s property assets.

Segment Gross Margin: Revenues less operating expenses, excluding depreciation, amortization and accretion, selling, general, administrative and development expense and other operating expenses. The Company believes this measure provides valuable insight into the site-level profitability of its assets.

Segment Operating Profit: Segment Gross Margin less selling, general, administrative and development expense, excluding stock-based compensation expense and corporate expenses. The Company believes this measure provides valuable insight into the site-level profitability of its assets while also taking into account the overhead expenses required to manage each of its operating segments.

Segment Operating Profit and Segment Gross Margin are before interest income, interest expense, gain (loss) on retirement of long-term obligations, other income (expense), net income (loss) attributable to noncontrolling interest and income tax benefit (provision).

Segment Operating Profit Margin: The percentage that results from dividing Segment Operating Profit by revenue.

Tenant Billings Growth: The increase or decrease resulting from a comparison of Tenant Billings for a current period with Tenant Billings for the corresponding prior-year period, in each case adjusted for foreign currency exchange rate fluctuations. The Company believes this measure provides valuable insight into the growth in recurring Tenant Billings and underlying demand for its real estate portfolio.

As a result, the Company now has six reportable segments: U.S. & Canada property (which includes all assets in the United States and Canada, other than its data center facilities and related assets), Africa & APAC property, Europe property, Latin America property, Data Centers and Services. This change aligns with the Company’s management structure and better aligns the Company’s reporting with management’s current approach of allocating costs and resources, managing growth and profitability and assessing the operating performance of its business segments.
