Boston, Massachusetts – July 30, 2024: American Tower Corporation (NYSE: AMT) today reported financial results for the quarter ended June 30, 2024.
Steven Vondran, American Tower’s Chief Executive Officer, stated, “The momentum from the start of the year extended into Q2, with core results highlighting the strong underlying demand for our portfolio of communications assets. Positive collection trends further accelerated in India, our U.S. & Canada segment delivered over 5% Organic Tenant Billings Growth and CoreSite achieved its second highest quarter of signed new business on record, all supporting over 13% Attributable AFFO per Share growth in the quarter, and our ability to raise the midpoints of the key financial measures in our updated 2024 outlook.
Furthermore, we continue to demonstrate our commitment to a disciplined approach to capital allocation. We’ve successfully accelerated certain proceeds associated with our pending sale of India ahead of our anticipated closing, and prudently managed our discretionary investments towards developed markets, while leveraging our global capabilities to maximize margins and profitability across our emerging markets footprint. We believe the successful execution of our strategic priorities, combined with the strong, durable secular trends underpinning our business, has American Tower positioned to deliver a best-in-class experience for our customers, and sustained growth with higher quality of earnings for our shareholders over the long-term.”

FULL YEAR 2024 OUTLOOK

The following full year 2024 estimates are based on a number of assumptions that management believes to be reasonable and reflect the Company’s expectations as of July 30, 2024. 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 July 30, 2024 through December 31, 2024: (a) 1,063 Argentinean Pesos; (b) 1.50 Australian Dollars; (c) 121.10 Bangladeshi Taka; (d) 5.45 Brazilian Reais; (e) 1.37 Canadian Dollars; (f) 950 Chilean Pesos; (g) 4,130 Colombian Pesos; (h) 0.93 Euros; (i) 15.35 Ghanaian Cedis; (j) 83.50 Indian Rupees; (k) 134 Kenyan Shillings; (l) 18.30 Mexican Pesos; (m) 1.63 New Zealand Dollars; (n) 1,600 Nigerian Naira; (o) 7,570 Paraguayan Guarani; (p) 3.80 Peruvian Soles; (q) 58.70 Philippine Pesos; (r) 18.60 South African Rand; (s) 3,810 Ugandan Shillings; and (t) 610 West African CFA Francs.
The Company’s outlook reflects estimated negative impacts of foreign currency exchange rate fluctuations to property revenue, Adjusted EBITDA and AFFO attributable to AMT common stockholders of approximately $51 million, $33 million and $28 million, respectively, relative to the Company’s prior 2024 outlook. 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 updated 2024 outlook assumes a full year contribution from the India business, including updated revenue reserve assumptions reflecting the positive collection trends realized year to date, and improved expectations for the remainder of the year. The updated 2024 outlook assumes a $96 million revenue reserve reversal for the India business, consisting of revenue reserve reversals of $29 million and $67 million in Q1 2024 and Q2 2024, respectively, with no additional revenue reserves, or reversals, assumed for the remainder of the year. The Company’s prior 2024 outlook had assumed a revenue reserve of $20 million for the full year. The Company’s outlook reflects India contributions of $1,270 million, $500 million and $410 million for property revenue, Adjusted EBITDA and Unlevered AFFO attributable to AMT common stockholders, respectively. The Company expects the closing of the sale of its India business (the “Pending ATC TIPL Transaction”) to occur in the second half of 2024, subject to customary closing conditions, including government and regulatory approval. Additional information pertaining to Unlevered AFFO attributable to AMT common stockholders and the expected contributions from India to the Company’s 2024 outlook has been provided on page 24 of the Company’s second quarter 2024 earnings presentation available on the Company’s website.
The Company is raising the midpoints of its full year 2024 outlook for property revenue, net income, net income attributable to AMT common stockholders, Adjusted EBITDA, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share by $20 million, $145 million, $135 million, $130 million, $85 million and $0.18, respectively. Excluding updates associated with the India business, and excluding the impacts of foreign exchange rate fluctuations, the Company’s updated 2024 outlook includes increases of $5 million, $62 million, $27 million and $0.06 for property revenue, Adjusted EBITDA, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share, respectively, and a decrease of $45 million to property revenue, an increase of $30 million in Adjusted EBITDA and no change to AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share when including foreign exchange rate fluctuations.
Additional information pertaining to the impact of foreign currency and Secured Overnight Financing Rate fluctuations on the Company’s outlook has been provided in the supplemental disclosure package available on the Company’s website.

For more information about American Tower, please visit the “Earnings Materials” and “Investor Presentations” sections of our investor relations hub at www.americantower.com.

Non-GAAP and Defined Financial Measures
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: Gross Margin, Operating Profit, 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 per Share, Unlevered AFFO attributable to AMT common stockholders, 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.
During the three months ended March 31, 2024, the Company updated its presentation of Nareit FFO attributable to American Tower Corporation common stockholders and AFFO attributable to American Tower Corporation common stockholders to remove separate presentation of Consolidated AFFO. The Company believes this presentation better aligns its reporting with management’s current approach of allocating capital and resources, managing growth and profitability and assessing the operating performance of its business. The change in presentation has no impact on the Company’s Nareit FFO attributable to American Tower Corporation common stockholders or AFFO attributable to American Tower Corporation common stockholders for any periods. Historical financial information included below has been adjusted to reflect the change in presentation.
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.
Revenue Components
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.
5



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.

Non-GAAP and Defined Financial Measure Definitions
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.
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.
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.
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.
Operating Profit: 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.
Operating Profit and 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).
Operating Profit Margin: The percentage that results from dividing Operating Profit by revenue.
Adjusted EBITDA: Net income before income (loss) from equity method investments, 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.
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. 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.
6



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, which includes the impact of noncontrolling interests 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 cause material fluctuations in Nareit FFO attributable to American Tower Corporation 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 per Share: AFFO attributable to American Tower Corporation common stockholders divided by the diluted weighted average common shares outstanding.
Unlevered AFFO attributable to AMT common stockholders: AFFO attributable to AMT common stockholders before deducting net interest charges. The Company believes this measure provides valuable insight into the India business’ contributions to the Company’s AFFO attributable to AMT common stockholders metric, before making assumptions on the use of proceeds for the Pending ATC TIPL Transaction.
Free Cash Flow: Cash provided by operating activities less total cash capital expenditures, including 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.
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.

Cautionary Language Regarding Forward-Looking Statements
This press release contains “forward-looking statements” concerning our goals, beliefs, expectations, strategies, objectives, plans, future operating results and underlying assumptions and other statements that are not necessarily based on historical facts. Examples of these statements include, but are not limited to, statements regarding our full year 2024 outlook and other targets, foreign currency exchange rates, our expectations regarding the potential impacts of the Adjusted Gross Revenue court ruling in India, including impacts on our customers’ payments, and factors that could affect such expectations, the creditworthiness and financial strength of our customers, the expected impacts of strategic partnerships on our business, our expectations for the closing of signed agreements, including the Pending ATC TIPL Transaction, and the expected impacts of such agreements on our business, our expectations regarding potential additional impairments in India and factors that could affect our expectations and our expectations regarding the leasing demand for communications real estate. Actual results may differ materially from those indicated in our forward-looking statements as a result of various important factors, including: (1) a significant decrease in leasing demand for our communications infrastructure would materially and adversely affect our business and operating results, and we cannot control that demand; (2) a substantial portion of our current and projected future revenue is derived from a small number of customers, and we are sensitive to adverse changes in the creditworthiness and financial strength of our customers; (3) if our customers consolidate their operations, exit their businesses or share site infrastructure to a significant degree, our growth, revenue and ability to generate positive cash flows could be materially and adversely affected; (4) increasing competition within our industries may materially and adversely affect our revenue; (5) our expansion initiatives involve a number of risks and uncertainties, including those related to integrating acquired or leased assets, that could adversely affect our operating results, disrupt our operations or expose us to additional risk; (6) new technologies or changes, or lack thereof, in our or a customer’s business model could make our communications infrastructure leasing business less desirable and result in decreasing revenues and operating results; (7) competition to purchase assets could adversely affect our ability to achieve our return on investment criteria; (8) strategic partnerships, and divestitures, such as the Pending ATC TIPL Transaction, may materially and adversely affect our financial condition, results of operations or cash flows; (9) our leverage and debt service obligations, including during a rising interest rates environment, may materially and adversely affect our ability to raise additional financing to fund capital expenditures, future growth and expansion initiatives and may reduce funds available to satisfy our distribution requirements; (10) rising inflation may adversely affect us by increasing costs beyond what we can recover through price increases; (11) restrictive covenants in the agreements related to our securitization transactions, our credit facilities and our debt securities could materially and adversely affect our business by limiting flexibility, and we may be prohibited from paying dividends on our common stock, which may jeopardize our qualification for taxation as a REIT; (12) our foreign operations are subject to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks associated with fluctuations in foreign currency exchange rates; (13) our business, and that of our customers, is subject to laws, regulations and administrative and judicial decisions, and changes thereto, that could restrict our ability to operate our business as we currently do or impact our competitive landscape; (14) we may be adversely affected by regulations related to climate change; (15) if we fail to remain qualified for taxation as a REIT, we will be subject to tax at corporate income tax rates, which may substantially reduce funds otherwise available, and even if we qualify for taxation as a REIT, we may face tax liabilities that impact earnings and available cash flow; (16) complying with REIT requirements may limit our flexibility or cause us to forego otherwise attractive opportunities; (17) we could have liability under environmental and occupational safety and health laws; (18) our towers, fiber networks, data centers or computer systems may be affected by natural disasters (including as a result of climate change) and other unforeseen events for which our insurance may not provide adequate coverage or result in increased insurance premiums; (19) if we, or third parties on which we rely, experience technology failures, including cybersecurity incidents or the loss of personally identifiable information, we may incur substantial costs and suffer other negative consequences, which may include reputational damage; (20) our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated; (21) if we are unable to protect our rights to the land under our towers and buildings in which our data centers are located, it could adversely affect our business and operating results; and (22) if we are unable or choose not to exercise our rights to purchase towers that are subject to lease and sublease agreements at the end of the applicable period, our cash flows derived from those towers will be eliminated. For additional information regarding factors that may cause actual results to differ materially from those indicated in our forward-looking statements, we refer you to the information that is provided in the section entitled “Risk Factors” in our most recent annual report on Form 10-K, and other risks described in documents we subsequently file from time to time with the Securities and Exchange Commission.

(1)There are no material impairment charges for the three months ended June 30, 2024. Three months ended June 30, 2023 includes impairment charges of approximately $37.5 million.
(2)Includes distributions to noncontrolling interest holders, distributions related to the outstanding mandatorily convertible preferred equity in connection with the Company’s 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)Three months ended June 30, 2024 include an adjustment for withholding taxes paid in India of $21.7 million, which were incurred as a result of the Pending ATC TIPL Transaction. We believe that these withholding tax payments 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)Three months ended June 30, 2024 and June 30, 2023 include losses on foreign currency exchange rate fluctuations of $21.7 million and $107.6 million, respectively.

(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.
