Organization, Consolidation and Presentation of Financial Statements [Abstract] |
General | GENERAL The unaudited condensed consolidated financial statements of Iron Mountain Incorporated, a Delaware corporation, and its subsidiaries ("we" or "us"), have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to those rules and regulations, but we believe that the disclosures included herein are adequate to make the information presented not misleading. The interim condensed consolidated financial statements are presented herein and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair presentation. Interim results are not necessarily indicative of results for a full year. The Condensed Consolidated Financial Statements and Notes thereto, which are included herein, should be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2024 included in our Annual Report on Form 10-K filed with the SEC on February 14, 2025 (our "Annual Report"). In September 2022, we announced a global program designed to accelerate the growth of our business ("Project Matterhorn"). See Note 10. We have been organized and have operated as a real estate investment trust for United States federal income tax purposes beginning with our taxable year ended December 31, 2014.
