Financial Statements and Exhibits Financial Statements: None Exhibits: Exhibit No. Description 99.1 Earnings Release dated November 5, 2026 and supplemental information 104 The cover page from this Current Report on Form 8-K formatted in Inline XBRL (included as Exhibit 101) The exhibit filed with this report contains measures of financial or operating performance that are not specifically defined by generally accepted accounting principles (“GAAP”) in the United States, including funds from operations (“FFO”), FFO per share, Real Estate FFO, Real Estate FFO per share, funds available for distribution, net operating income (“NOI”), domestic property NOI and portfolio NOI. FFO and NOI are performance measures that are standard in the REIT business. We believe FFO and NOI provide investors with additional information concerning our operating performance and a basis to compare our performance with the performance of other REITs. We also use these measures internally to monitor the operating performance of our portfolio. Our computation of these non-GAAP measures may not be the same as similar measures reported by other REITs. These non-GAAP financial measures should not be considered as alternatives to net income as a measure of our operating performance or to cash flow
