The Company’s 2024 results, for the purposes of the growth rates described below, are presented on a continuing operations basis, with the exception of Net Income, Net Income attributable to AMT common stockholders, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share. The Company is raising the midpoints of its full year 2025 outlook for property revenue, Adjusted EBITDA, AFFO attributable to AMT common stockholders and AFFO attributable to AMT common stockholders per Share by $40 million, $45 million, $50 million and $0.10, respectively, primarily as a result of estimated positive foreign currency exchange rate fluctuations described above. The Company is increasing the midpoint for net income and net income attributable to AMT common stockholders by $95 million and $40 million, respectively, primarily due to unrealized foreign currency gains. The increase, driven by unrealized foreign currency gains, to net income attributable to AMT common stockholders is partially offset by increased minority interests as a result of a recent tax law change in Europe. Additional information pertaining to the impact of foreign currency and Secured Overnight Financing Rate fluctuations on the Company’s outlook has been provided in the supplemental disclosure package available on the Company’s website. 3 2025 Outlook: ($ in millions, except per share amounts.)
