| Amendment Description | This Amendment No. 1 to the combined Annual Report on Form 10-K for the fiscal year ended December 31, 2020 of Medical Properties Trust, Inc. and MPT Operating Partnership, L.P. is filed for the sole purpose of amending Item 15 of Part IV to include the consolidated financial statements of Steward Health Care System LLC (“Steward”), which were not available at the time the combined Annual Report on Form 10-K was initially filed. At December 31, 2020, our properties leased to Steward constituted more than 20% of our assets and these properties were leased to Steward under long-term, triple-net leases that transfer substantially all operating costs to Steward and Steward’s financial statements may thus be material to investors. The audited financial statements of Steward as of, and for the years then ended, December 31, 2020 and 2019 are attached to this report as Exhibit 99.1. These financial statements were provided to us by Steward, and Medical Properties Trust, Inc. did not participate in their preparation or review. Other than as expressly set forth above, this Amendment does not, and does not purport to, update or restate the information in any other Item of the originally filed annual report. This Amendment consists solely of the preceding cover page, this explanatory note, the information required by Item 15 of Form 10-K as provided in Exhibit 99.1, an updated exhibit index, a signature page, the accountants’ consent for Steward’s audited financial statements, and the certifications required to be filed as exhibits hereto. | ||
