American Tower Corporation (NYSE: AMT) today reported financial results for the quarter ended September 30, 2023.

Tom Bartlett, American Tower’s Chief Executive Officer, stated, “We had a strong quarter, as our global portfolio of communications assets continued to demonstrate resiliency in an increasingly challenging macroeconomic environment. Our consolidated tower business again drove Organic Tenant Billings Growth of over 6%, while revenue growth in our U.S. data center business, where we’re positioned to deliver a second consecutive year of record new leasing, was over 9%. This performance, coupled with an on-going focus towards cost management, drove Attributable AFFO per Share growth of over 9%. As a result of our strong results, and a high degree of visibility through the balance of the year, we are pleased to again raise our full year outlook for property revenue, Adjusted EBITDA and Attributable AFFO, and remain encouraged by our positioning as we look forward to 2024.

As the 5G investment cycle continues and data consumption growth persists, we remain focused on driving attractive organic growth rates across our existing portfolio, leveraging our global capabilities and operational efficiency to manage costs and support an expanding margin profile, as well as strengthening our balance sheet and capital resources to provide financial flexibility. Taken altogether, we believe we are well positioned to deliver strong, sustained growth and compelling returns for our shareholders over the long-term.”

Please refer to “Non-GAAP and Defined Financial Measures” below for definitions and other information regarding the Company’s use of non-GAAP measures. For financial information and reconciliations to GAAP measures, please refer to the “Unaudited Selected Consolidated Financial Information” below.

CAPITAL ALLOCATION OVERVIEW

Distributions – During the quarter ended September 30, 2023, the Company declared the following regular cash distributions to its common stockholders:

Capital Expenditures – During the third quarter of 2023, total capital expenditures were approximately $408 million, of which $60 million was for non-discretionary capital improvements and corporate capital expenditures. For additional capital expenditure details, please refer to the supplemental disclosure package available on the Company’s website.

Acquisitions – During the third quarter of 2023, the Company spent approximately $61 million, primarily to acquire sites related to a sublease agreement with SBC Communications Inc., a predecessor entity to AT&T Inc., as well as other communications infrastructure assets.

Other Events – The Company concluded that a triggering event occurred as of September 30, 2023 with respect to its India reporting unit primarily due to indications of value received from third parties in connection with the Company’s review of various strategic alternatives for its India operations, including the potential sale of equity interests in its India operations. As a result, the Company performed an interim quantitative goodwill impairment test as of September 30, 2023 using, among other things, the information obtained from third parties to compare the fair value of the India reporting unit to its carrying amount, including goodwill. The result of the Company’s interim goodwill impairment test as of September 30, 2023 indicated that the carrying amount of the Company's India reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $322 million. The goodwill impairment charge is recorded in Goodwill impairment in the accompanying consolidated statements of operations.

LEVERAGE AND FINANCING OVERVIEW

Leverage – For the quarter ended September 30, 2023, the Company’s Net Leverage Ratio was 5.0x net debt (total debt less cash and cash equivalents) to third quarter 2023 annualized Adjusted EBITDA.

Liquidity and Financing Activities – As of September 30, 2023, the Company had approximately $9.7 billion of total liquidity, consisting of approximately $2.1 billion in cash and cash equivalents plus the ability to borrow an aggregate of approximately $7.6 billion under its revolving credit facilities, net of any outstanding letters of credit.

On September 15, 2023, the Company issued an aggregate of $1.5 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.

FULL YEAR 2023 OUTLOOK

The following full year 2023 estimates are based on a number of assumptions that management believes to be reasonable and reflect the Company’s expectations as of October 26, 2023. 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 October 26, 2023 through December 31, 2023: (a) 532 Argentinean Pesos; (b) 1.56 Australian Dollars; (c) 111.20 Bangladeshi Taka; (d) 5.00 Brazilian Reais; (e) 1.36 Canadian Dollars; (f) 890 Chilean Pesos; (g) 4,120 Colombian Pesos; (h) 0.94 Euros; (i) 11.50 Ghanaian Cedis; (j) 83.10 Indian Rupees; (k) 147 Kenyan Shillings; (l) 17.60 Mexican Pesos; (m) 1.69 New Zealand Dollars; (n) 850 Nigerian Naira; (o) 7,280 Paraguayan Guarani; (p) 3.75 Peruvian Soles; (q) 56.80 Philippine Pesos; (r) 19.20 South African Rand; (s) 3,740 Ugandan Shillings; and (t) 620 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 $28 million, $14 million and $5 million, respectively, relative to the Company’s prior 2023 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 is raising the midpoints of its full year 2023 outlook for property revenue, Adjusted EBITDA, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share by $60 million, $60 million, $40 million and $0.09, respectively. The Company is reducing the midpoint for net income and net income attributable to AMT common stockholders, each by $90 million, primarily due to the goodwill impairment charges in India.

The Company’s outlook reflects India contributions of $1,095 million, $355 million and $290 million for property revenue, Adjusted EBITDA and Unlevered AFFO attributable to AMT common stockholders, defined as AFFO attributable to AMT common stockholders before deducting net interest charges, respectively.

Additional information pertaining to the impact of foreign currency and Secured Overnight Financing Rate (“SOFR”) fluctuations on the Company’s outlook has been provided in the supplemental disclosure package available on the Company’s website.

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, Consolidated Adjusted Funds From Operations (AFFO), 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.

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. 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.

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 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 less dividends to noncontrolling interests, and including adjustments for (i) unconsolidated affiliates and (ii) 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.

Consolidated Adjusted Funds From Operations (AFFO): 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, (viii) other operating income (expense), and adjustments for (ix) unconsolidated affiliates and (x) noncontrolling interests, less cash payments related to capital improvements and cash payments related to corporate capital expenditures. The Company believes this measure provides valuable insight into the operating performance of its property assets by further adjusting the Nareit FFO 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 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.

Adjusted Funds From Operations (AFFO) attributable to American Tower Corporation common stockholders: Consolidated AFFO, excluding the impact of noncontrolling interests on both Nareit FFO attributable to American Tower Corporation common stockholders and the other line items included in the calculation of Consolidated AFFO. The Company believes that providing this additional metric 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 is valuable given the on-going strategic review of its India business, and 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 a potential sale of equity interests in the business.

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 finance lease liabilities, less cash and cash equivalents.

Net Leverage Ratio: Net Debt 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.
