Liquidity – As of September 30, 2019, the Company had $5.2 billion of total liquidity, consisting of $1.4 billion in cash and cash equivalents plus the ability to borrow an aggregate of $3.8 billion under its revolving credit facilities, net of any outstanding letters of credit.

On October 3, 2019, the Company issued $750.0 million aggregate principal amount of 2.750% senior unsecured notes due 2027 and $600.0 million aggregate principal amount of 3.700% senior unsecured notes due 2049. The Company used the net proceeds to repay existing indebtedness under its 2013 credit facility and its 2019 term loan.

FULL YEAR 2019 OUTLOOK

The following full year 2019 financial and operational estimates are based on a number of assumptions that management believes to be reasonable and reflect the Company’s expectations as of October 31, 2019. 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 31, 2019 through December 31, 2019: (a) 64.20 Argentinean Pesos; (b) 4.15 Brazilian Reais; (c) 720 Chilean Pesos; (d) 3,440 Colombian Pesos; (e) 0.91 Euros; (f) 5.45 Ghanaian Cedi; (g) 71.50 Indian Rupees; (h) 104 Kenyan Shillings; (i) 19.70 Mexican Pesos; (j) 360 Nigerian Naira; (k) 6,400 Paraguayan Guarani; (l) 3.35 Peruvian Soles; (m) 15.05 South African Rand; and (n) 3,690 Ugandan Shillings.

The Company is raising the midpoint of its full year 2019 outlook for property revenue, net income, Adjusted EBITDA and Consolidated AFFO by $180 million, $145 million, $180 million and $5 million, respectively, as compared to the Company’s outlook issued on July 31, 2019. The increases in property revenue, net income and Adjusted EBITDA include approximately $167 million in additional straight-line revenue as a result of the Company’s new MLA with AT&T.

The Company’s outlook reflects estimated unfavorable impacts of foreign currency exchange rate fluctuations to property revenue, Adjusted EBITDA and Consolidated AFFO, of approximately $32 million, $16 million and $13 million, respectively, as compared to the Company’s outlook issued on July 31, 2019. The impact of foreign currency exchange rate fluctuations on net income is not provided, as the impact on all components of the net income measure cannot be calculated without unreasonable effort.

The Company’s full year 2019 outlook also reflects estimated cumulative expected unfavorable impacts of ICCC on property revenue, Adjusted EBITDA and Consolidated AFFO of approximately $367 million, $254 million and $203 million, respectively, inclusive of an expected reduction in pass-through revenue of approximately $84 million and the benefit of approximately $27 million in ICCC-related settlement payments in 2019. The expected 2019-specific impacts of ICCC to property revenue, Adjusted EBITDA and Consolidated AFFO are $178 million, $134 million and $107 million, respectively, including $23 million in lower pass-through revenue and the benefit of ICCC-related settlement payments. At this time, the Company expects the impacts of ICCC to last throughout the remainder of 2019. The Company is providing key outlook measures adjusted to quantify the impacts of ICCC on such measures and the impact of ICCC and the Company’s settlement with Tata Teleservices and related entities (“Tata”) in the fourth quarter of 2018 on growth rates as it believes that these adjusted measures better reflect the long-term trajectory of its recurring business and provide investors with a more comprehensive analysis of the Company’s operations. The impacts of ICCC and the Tata settlement on net income are not provided, as the impact on all components of the net income measure cannot be calculated without unreasonable effort.

Additional information pertaining to the impact of foreign currency, London Interbank Offered Rate (“LIBOR”) fluctuations and ICCC 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, Consolidated AFFO per Share, AFFO attributable to American Tower Corporation common stockholders per Share, Free Cash Flow, Net Debt, Net Leverage Ratio and Indian Carrier Consolidation-Driven Churn (ICCC). 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 tenant settlements and fiber solutions 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.

Indian Carrier Consolidation-Driven Churn (ICCC): Tenant cancellations specifically attributable to short-term carrier consolidation in India. Includes impacts of carrier exits from the marketplace and carrier cancellations as a result of consolidation, but excludes normal course churn. The Company believes that providing this additional metric enhances transparency and provides a better understanding of its recurring business without the impact of what it believes to be a transitory event.

Gross Margin: Revenues less operating expenses, excluding stock-based compensation expense recorded in costs of operations, 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.

For segment reporting purposes, in periods through the third quarter of 2018, the Latin America property segment Operating Profit and Gross Margin also include interest income (expense), TV Azteca, net. 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), 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 and dividends on preferred stock, 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, (iv) non-real estate related depreciation, amortization and accretion, (v) amortization of deferred financing costs, capitalized interest, 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 Indian and European businesses.

Consolidated AFFO per Share: Consolidated AFFO 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 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.

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 2019 outlook and other targets, our expectations regarding Indian Carrier Consolidation-Driven Churn (ICCC) and factors that could affect such expectations, foreign currency exchange rates, our expectations for the closing of signed acquisitions, our expectations for the redemption of shares in ATC TIPL, our expectations for the acquisition of MTN Group Limited’s interests 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) increasing competition within our industry may materially and adversely affect our revenue; (3) if our tenants consolidate their operations, exit the telecommunications business 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) our business is subject to government and tax regulations and changes in current or future laws or regulations could restrict our ability to operate our business as we currently do or impact our competitive landscape; (5) 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; (6) a substantial portion of our revenue is derived from a small number of tenants, and we are sensitive to changes in the creditworthiness and financial strength of our tenants; (7) 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; (8) new technologies or changes in our or a tenant’s business model could make our tower leasing business less desirable and result in decreasing revenues and operating results; (9) competition for assets could adversely affect our ability to achieve our return on investment criteria; (10) our leverage and debt service obligations may materially and adversely affect our ability to raise additional financing to fund capital expenditures, future growth and expansion initiatives and to satisfy our distribution requirements; (11) 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; (12) complying with REIT requirements may limit our flexibility or cause us to forego otherwise attractive opportunities; (13) 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; (14) our towers, fiber networks, data centers or computer systems may be affected by natural disasters, security breaches and other unforeseen events for which our insurance may not provide adequate coverage; (15) our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated; (16) we could have liability under environmental and occupational safety and health laws; (17) if we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results; and (18) 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 contained in Item 1A of our Form 10-K for the year ended December 31, 2018, under the caption “Risk Factors”. We undertake no obligation to update the information contained in this press release to reflect subsequently occurring events or circumstances.
