Under Section 404 of the Sarbanes-Oxley Act of 2002, the REIT’s management is required to assess the effectiveness of the REIT’s internal control over financial reporting as of the end of each fiscal year, and report on the basis of that assessment whether the REIT’s internal control over financial reporting is effective.

The REIT’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The REIT’s internal control over financial reporting includes those policies and procedures that:

There are inherent limitations in the effectiveness of any system of internal control, including the possibility of human error and the circumvention or overriding of controls.

Under the supervision, and with the participation, of the REIT’s management, including the principal executive officer and principal financial officer, management conducted a review, evaluation and assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025, based on criteria established inInternal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

The effectiveness of our internal control over financial reporting as of December 31, 2025, has been audited by KPMG LLP (Philadelphia, Pennsylvania; PCAOB ID #185), an independent registered public accounting firm, as stated in their report that appears herein.
