Boston, Massachusetts – July 28, 2016: American Tower Corporation (NYSE: AMT) today reported financial results for the quarter ended June 30, 2016.

Jim Taiclet, American Tower’s Chief Executive Officer stated, “Our Company’s strong second quarter total Property Revenue growth of nearly 24% was powered by solid U.S. Organic Tenant Billings Growth of nearly 6%, and more than double that level in our international markets, at approximately 14%. Total Organic Tenant Billings grew by approximately 8% in the quarter and were further enhanced by an approximately 15% contribution in New Site Tenant Billings associated primarily with our Viom transaction in India and sites acquired from Bharti Airtel in Nigeria and TIM in Brazil.

American Tower’s consistent track record of performance is based on 20 years of dedication to developing a leadership position in the physical, intellectual and organizational capital that enables us to provide high quality telecommunications real estate to the world’s largest network operators in the U.S., Latin America, Asia and EMEA. We therefore believe that our company has built a sustainable competitive advantage that will drive continuing growth in Consolidated AFFO per share and in our dividend for many years to come.”

FULL YEAR 2016 OUTLOOK

Please note that certain outlook disclosures have been updated in response to the Securities and Exchange Commission’s recently updated Compliance and Disclosure Interpretations on the use of non-GAAP financial measures. For comparability, outlook tables in their previous format, updated for our current expectations, have been included in the Appendix of this press release. Please note that in future disclosures, the tables in the previous format will no longer be available.

The following estimates are based on a number of assumptions that management believes to be reasonable and reflect the Company’s expectations as of July 28, 2016. 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 is raising the midpoint of its full year 2016 outlook for property revenue, Adjusted EBITDA and Consolidated AFFO by $10 million, $15 million and $15 million, respectively. This includes an approximately $7 million negative impact on all three metrics from the revenue reserve we recorded in Brazil in the second quarter as well as the impacts of foreign currency exchange fluctuations, as outlined below. The Company is reducing the midpoint of its full year 2016 outlook for net income by $70 million primarily as a result of increased expected depreciation and amortization expense.

The Company’s revised outlook is based on the following average foreign currency exchange rates to 1.00 U.S. Dollar for the second half of 2016: (a) 3.50 Brazilian Reais; (b) 670 Chilean Pesos; (c) 3,100 Colombian Pesos; (d) 0.92 Euros; (e) 4.00 Ghanaian Cedi; (f) 68.40 Indian

Rupees; (g) 18.90 Mexican Pesos; (h) 300 Nigerian Naira; (i) 3.40 Peruvian Soles; (j) 15.75 South African Rand; and (k) 3,400 Ugandan Shillings.

Based on these assumptions, the Company’s current outlook reflects favorable impacts of foreign currency fluctuations of approximately $1 million for total property revenue, $17 million for Adjusted EBITDA and $18 million for Consolidated AFFO, as compared to the Company’s previously issued full year outlook. Additional information pertaining to the impact of foreign currency fluctuations on the Company’s outlook has been provided in the supplemental disclosure package available on its website. The impact of foreign currency fluctuations on net income is not provided, as the impact on all components of the net income measure cannot be calculated without unreasonable effort.

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 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. Notwithstanding the foregoing, 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; and (vii) 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 towers 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 initial addition to our portfolio is not included in New Site Tenant Billings. The Company believes providing New Site Tenant Billings enhances an investor’s ability to analyze our existing real estate portfolio growth as well as our 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 initial 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, we believe 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, we believe 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 from 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 our real estate portfolio, (i.e.: does not have a renewal

5

option or escalation as our tenant leases do) we believe 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 respective 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 fluctuations to its reported growth to provide transparency into the underlying performance of its real estate business.

Other revenue: Typically an immaterial portion of the Company’s total revenue, Other revenue represents revenue not captured by the above listed terms and can include items such as tenant settlements.

Non-GAAP and Defined Financial Measure Definitions

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, and 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.

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 fluctuations. The Company believes this measure provides valuable insight into the growth in recurring Tenant Billings and underlying demand for its real estate portfolio.

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, the Latin America property segment Operating Profit and Gross Margin also include interest income, 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 our 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 interest. 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 our 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 its tax provision, (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 interest, 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

6

underlying performance of our property assets in those periods. In addition, it is a widely used performance measure across our telecommunications real estate sector.

Adjusted Funds From Operations (AFFO) attributable to American Tower Corporation common stockholders: Consolidated AFFO, excluding the impact of noncontrolling interest on both NAREIT FFO attributable to American Tower Corporation common stockholders as well as the other line items included in the calculation of Consolidated AFFO. The company believes that providing this additional metric enhances transparency, given a significantly larger minority interest component of its business as a result of the Company’s Viom transaction, which closed in the second quarter of 2016.

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 capital leases of property and equipment. 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.

Net Debt: Total long-term debt 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.

APPENDIX: Updated 2016 Full Year Outlook Measures, Utilizing Previously Disclosed Outlook Format

PLEASE NOTE: This appendix has been provided for comparability purposes, relative to the Company’s previously issued outlook. Going forward, the Company will issue outlook in the format contained in the body of this press release. The format below will no longer be provided beginning in the third quarter of 2016.

The Company’s outlook for 2016 reflects the following:($ in millions)
	Full Year 2016					Midpoint Growth	Midpoint Core Growth(1)
Total property revenue	$	5,615	to	$	5,705	20.9%	21.4	%
Net Income	965		to	1,025		48.1%	N/A
Adjusted EBITDA(1)	3,500		to	3,540		14.8%	20.1	%
Consolidated AFFO(1)	2,420		to	2,460		13.5%	17.1	%

_______________

(1) See “Non-GAAP and Defined Financial Measures” above.

The Company’s outlook for total property revenue reflects the following, at the midpoint: ($ in millions)
	Segment Revenue		Organic Core Growth(1)	International Pass-through Revenue(2)		Straight-line Revenue(2)
U.S. property revenue	$	3,370	~5.5%	$	—	$	73
Total international property revenue	2,290		~12%	706		51
Total property revenue	$	5,660	~7%	$	706	$	124

_______________

(1) See “Non-GAAP and Defined Financial Measures” above.

(2) Included in Segment Revenue totals but excluded from Core Growth and Organic Core Growth.

The calculation of outlook midpoint Core Growth is as follows: (Totals may not add due to rounding.)
	Total Property Revenue		Adjusted EBITDA(1)		Consolidated AFFO(1)
Outlook midpoint Core Growth	21.4	%	20.1	%	17.1	%
Estimated impact of pass-through revenues	4.6	%	—	%	—	%
Estimated impact of fluctuations in foreign currency exchange rates	(3.5	)%	(3.1	)%	(3.2	)%
Estimated impact of straight-line revenue and expense recognition	(1.4	)%	(1.9	)%	—	%
Estimated Impact of significant one-time items(1)	(0.2	)%	(0.3	)%	(0.4	)%
Outlook midpoint growth	20.9	%	14.8	%	13.5	%

_______________

(1) See “Non-GAAP and Defined Financial Measures” above.

Total Property Revenue Core Growth Components(1): (Totals may not add due to rounding.)	Full Year 2016
Organic Core Growth	~7%
New Property Core Growth(2)	~14%
Core Growth	~21%

_______________

(1) Reflects growth at the midpoint of outlook ranges.

(2) Reflects revenue growth at sites that have been under American Tower’s ownership or control since the beginning of the prior-year period.

Core Growth: (Total property revenue, Adjusted EBITDA and Consolidated AFFO) the increase or decrease, expressed as a percentage, resulting from a comparison of financial results for a current period with corresponding financial results for the corresponding period in a prior-year, in each case, excluding the impact of pass-through revenue (expense), where applicable, straight-line revenue and expense recognition, foreign currency exchange rate fluctuations and significant one-time items. The Company believes that Core Growth provides valuable insight into the underlying trends of its business by adjusting for the items outlined above, which, if unadjusted for, may distort the operating trends of its business.

15

Organic Core Growth: the increase or decrease in property revenue, expressed as a percentage, resulting from a comparison of financial results for a current period with corresponding financial results for the corresponding period in a prior-year, in each case, excluding the impact of pass-through revenue (expense), straight-line revenue and expense recognition, foreign currency exchange rate fluctuations, significant one-time items and revenue associated with new properties that the Company has added to the portfolio since the beginning of the prior-year period. The Company believes that organic growth is a useful measurement of its ability to add tenancy and incremental revenue to its existing assets for the reported period, and enables investors and analysts to gain additional insight into the relative attractiveness, and therefore the value, of the Company’s property assets. The organic tenant billings metric discussed earlier provides a similar function, and will replace the organic core growth metric beginning in the third quarter.
