As a result of our robust first quarter performance and recent acquisition activities, we have increased the midpoint of our full year 2012 outlook for rental and management revenue, Adjusted EBITDA and AFFO growth to over 16%, 14% and 11%, respectively.

Furthermore, we are currently committed to deploying over $1.5 billion of capital during 2012, which includes spending on our annual capital expenditure program and acquisitions we have under contract today, as well as our regular distributions.

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, Recurring Free Cash Flow, Recurring Free Cash Flow per Share, Funds From Operations, Adjusted Funds From Operations, Adjusted Funds From Operations per Share, Core Growth and Net Leverage Ratio. 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 equity method investments, income taxes and discontinued operations. The Company defines Operating Profit Margin as Operating Profit divided 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 Recurring Free Cash Flow as Adjusted EBITDA before straight-line revenue and expense, plus interest income, less interest expense, cash paid

5

for income taxes and cash payments related to redevelopment, capital improvement and corporate capital expenditures. The Company defines Recurring Free Cash Flow per Share as Recurring Free Cash Flow divided by the diluted weighted average common shares outstanding. 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-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, Adjusted Funds From Operations and Adjusted Funds From Operations per Share for the three months ended March 31, 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, Recurring Free Cash Flow, Recurring Free Cash Flow per Share, 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.

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 customer 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 customer 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 March 31, 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 impairments and transaction related costs.
