Boston, Massachusetts – August 1, 2012: American Tower Corporation (NYSE: AMT) today reported financial results for the quarter ended June 30, 2012.

Jim Taiclet, American Tower’s Chief Executive Officer stated, “During the second quarter, we continued to translate strong global wireless trends into solid performance. We added substantial new lease and amendment business in both the U.S. and across our global markets, and for the first time in our company’s history, our international segment generated higher commenced new business than our domestic segment.

As a result, we delivered Core Growth that was ahead of internal expectations in all of our key business metrics, including 23% growth in rental revenue and 24% growth in Adjusted EBITDA. Our expectations for the full year are that disciplined cost management and outperformance in our core business will exceed potential headwinds from foreign currency fluctuations, and we are therefore maintaining our full year 2012 outlook for rental revenue and raising outlook for Adjusted EBITDA and AFFO.”

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, Funds From Operations, Adjusted Funds From Operations, Adjusted Funds From Operations per Share, Core Growth and Net Leverage Ratio. As a result of significant non-cash changes to the carrying amount of our long-term deferred income tax assets, as reflected in the income tax provision, the Company has adjusted its definition of Adjusted Funds From Operations to reflect cash taxes paid. The Company believes that this revised methodology more accurately reflects the ongoing cash obligation of the Company’s current income tax liabilities.

The Company defines Gross Margin as revenues less operating expenses, excluding stock-based compensation expense. The Company defines Operating Profit as Gross Margin less selling, general, administrative and development expense, excluding stock-based compensation expense and corporate expenses. For reporting purposes, the international rental and management segment Operating Profit and Gross Margin also include interest income, TV Azteca, net. These measures of Gross Margin and Operating Profit are also before interest income, interest expense, loss on retirement of long-term obligations, other income (expense), net income attributable to non-controlling interest, income (loss) on

6

equity method investments, income taxes and discontinued operations. The Company defines Operating Profit Margin as the percentage that results from dividing Operating Profit by revenue. The Company defines Adjusted EBITDA as net income before income (loss) from discontinued operations, net, income (loss) from equity method investments, income tax provision (benefit), other (income) expense, loss on retirement of long-term obligations, interest expense, interest income, other operating expenses, depreciation, amortization and accretion and stock-based compensation expense. The Company defines Adjusted EBITDA Margin as the percentage that results from dividing Adjusted EBITDA by total revenue. The Company defines Funds From Operations as net income before real estate related depreciation, amortization and accretion. The Company defines Adjusted Funds From Operations as Funds From Operations before straight-line revenue and expense, stock-based compensation expense, non-cash portion of tax provision, non-real estate related depreciation, amortization and accretion, amortization of deferred financing costs, debt discounts and capitalized interest, other (income) expense, loss on retirement of long-term obligations, other operating (income) expense, less cash payments related to capital improvements and cash payments related to corporate capital expenditures. The Company defines Adjusted Funds From Operations per Share as Adjusted Funds From Operations divided by the diluted weighted average common shares outstanding. Funds From Operations for the three and six months ended June 30, 2011 are presented on a pro forma basis and reflect adjustments for income tax provision as if the REIT conversion had occurred on January 1, 2011. The Company defines Core Growth in total rental and management revenue and Adjusted EBITDA as 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 straight-line revenue and expense recognition, foreign currency exchange rate fluctuations and significant one-time items. The Company defines Net Leverage Ratio as net debt (total debt, less cash and cash equivalents) divided by last quarter annualized Adjusted EBITDA. 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. The Company believes that these measures can assist in comparing company performances on a consistent basis irrespective of depreciation and amortization or capital structure. Depreciation and amortization can vary significantly among companies depending on accounting methods, particularly where acquisitions or non-operating factors, including historical cost bases, are involved. Notwithstanding the foregoing, the Company’s measures of Gross Margin, Operating Profit, Operating Profit Margin, Adjusted EBITDA, Adjusted EBITDA Margin, Funds From Operations, Adjusted Funds From Operations, Adjusted Funds From Operations per Share, Core Growth and Net Leverage Ratio may not be comparable to similarly titled measures used by other companies.

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 2012 outlook, foreign currency exchange rates and our expectation regarding the declaration of regular distributions. Actual results may differ materially from those indicated in our forward-looking statements as a result of various important factors, including: (1) decrease in demand for our communications sites would materially and adversely affect our operating results and we cannot control that demand; (2) if our tenants consolidate, merge or share site infrastructure with each other to a significant degree, our growth, revenue and ability to generate positive cash flows could be materially and adversely affected; (3) new technologies or changes in a tenant’s business model could make our tower leasing business less desirable and result in decreasing revenues; (4) our expansion initiatives may disrupt our operations or expose us to additional risk if we are not able to successfully integrate operations, assets and personnel; (5) if we fail to qualify as a REIT or fail to remain qualified as a REIT, we would be subject to tax at corporate income tax rates, which would substantially reduce funds available; (6) we could suffer adverse tax and other financial consequences if taxing authorities do not agree with our tax positions; (7) failure to make required distributions would subject us to federal corporate income tax, which may limit our ability to fund these distributions using cash generated through our taxable REIT subsidiaries (TRSs); (8) certain of our business activities will be subject to corporate level income tax and foreign taxes, which will reduce our cash flows, and we will have potential deferred and contingent tax liabilities; (9) complying with REIT requirements may limit our flexibility or cause us to forego otherwise attractive opportunities; (10) our extensive use of TRSs, in particular for our international operations, may cause us to fail to qualify as a REIT; (11) 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; (12) our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business as we currently do; (13) a substantial portion of our revenue is derived from a small number of tenants; (14) due to the long-term expectations of revenue growth from tenant leases, we are sensitive to changes in the creditworthiness and financial strength of our tenants; (15) if we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results; (16) we may need additional financing to fund capital expenditures, future growth and expansion initiatives and satisfy our REIT distribution requirements; (17) our leverage and debt service obligations may materially and adversely affect us; (18) restrictive covenants in the loan agreements related to our Securitization, the loan agreements for the credit facilities and the indentures governing our debt securities could materially and adversely affect our business by limiting flexibility; (19) increasing competition in the tower industry may create pricing pressures that may materially and adversely affect us; (20) 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 such towers would be eliminated; (21) we may incur goodwill and other intangible impairment charges which may require us to record a significant charge to earnings; (22) we have limited experience operating as a REIT, which may adversely affect our financial condition, results of operations, cash flow, per share trading price of our common stock and ability to satisfy debt service obligations; (23) distributions payable by REITs generally do not qualify for reduced tax rates; (24) we could have liability under environmental and occupational safety and health laws; (25) our towers or data centers may be affected by natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage; and (26) our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated. 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-Q for the three months ended March 31, 2012. We undertake no obligation to update the information contained in this press release to reflect subsequently occurring events or circumstances.

Total rental and management straight-line revenue and expense:

In accordance with GAAP, the Company recognizes consolidated rental and management revenue and expense related to non-cancellable tenant and ground lease agreements with fixed escalations on a straight-line basis, over the applicable lease term. As a result, the Company’s revenue recognized may differ materially from the amount of cash collected per tenant lease, and the Company’s expense incurred may differ materially from the amount of cash paid per ground lease. Additional information regarding straight-line accounting can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 in the section entitled “Revenue Recognition,” of note 1, “Business and Summary of Significant Accounting Policies” within the notes to the consolidated financial statements. A summary of total rental and management straight-line revenue and expense, which represents the non-cash revenue and expense recorded due to straight-line recognition, is as follows:

(1) Adjustment for June 30, 2011 assumes the REIT election occurred on January 1, 2011, and that as a result, income taxes would no longer be payable on certain of the Company’s activities. As a result, on a pro forma basis, income tax expense is lower by the amount of the adjustment. For more information, see Note (B) to Unaudited Pro Forma Consolidated Financial Statements in the Company’s Definitive Proxy Statement, filed with the SEC on October 11, 2011. The pro forma adjustment set forth in this footnote has been made solely for the purpose of this pro forma information. This information is not necessarily indicative of the financial position or operating results that would have been achieved had the REIT election been completed as of January 1, 2011, nor is it necessarily indicative of future financial position or operating results. It also does not reflect one-time transaction costs related to the REIT election and the potential immaterial effect of lower cash balances these transactions have on interest income, higher borrowing costs or foregone investment opportunities.

(2) Primarily includes unrealized loss (gain) on foreign currency exchange rate fluctuations.

(3) Primarily includes impairments and transaction related costs.
