Boston, Massachusetts – July 31, 2013: American Tower Corporation (NYSE: AMT) today reported financial results for the quarter ended June 30, 2013.

Jim Taiclet, American Tower’s Chief Executive Officer stated, “During the second quarter of 2013, our Core results significantly outperformed our internal expectations as demand for tower space drove robust leasing activity across our global portfolio. The combination of our extensive, high quality asset base and long-term master lease agreements with leading mobile operators resulted in strong growth in each of our key operating metrics.

We expect the favorable leasing trends we have seen so far this year to continue generating solid Core performance, offsetting potential headwinds from the translation of foreign currency exchange rates. As a result, we are reaffirming our full year outlook for total rental and management revenue and raising our full year outlook for Adjusted EBITDA by $5 million and AFFO by $10 million.”

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, Adjusted Funds From Operations, Adjusted Funds From Operations per Share, Core Growth and Net Leverage Ratio. The Company uses Funds From Operations as defined by the National Association of Real Estate Investment Trusts (NAREIT), referred to herein as NAREIT Funds From Operations.

The Company defines Gross Margin as 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 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 equity method investments and income taxes. 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) on 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 income (expense), 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. NAREIT Funds From Operations is defined as net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges and real estate related depreciation, amortization and accretion, and including adjustments for (i) unconsolidated affiliates and (ii) noncontrolling interest. The Company defines Adjusted Funds From Operations as NAREIT Funds From Operations before (i) straight-line revenue and expense, (ii) stock-based compensation expense, (iii) the non-cash portion of our tax provision, (iv) non-real estate related depreciation, amortization and accretion, (v) amortization of deferred financing costs, capitalized interest and debt discounts and premiums, (vi) other income (expense), (vii) 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 defines Adjusted Funds From Operations per Share as Adjusted Funds From Operations divided by the diluted weighted average common shares outstanding. The Company defines Core Growth in total rental and management revenue, Adjusted EBITDA and Adjusted Funds From Operations 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, NAREIT 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.
