Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures as such term is defined under Rule 13a-15(e) under the Exchange Act. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2026, to provide reasonable assurance that information required to be disclosed in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management necessarily applies its judgment in assessing the costs and benefits of such disclosure controls and procedures that, by their nature, can only provide reasonable assurance regarding management's control objectives. Also, we have investments in certain unconsolidated entities that we do not control or manage.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the three months ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Starting with the third quarter of 2025, our Company is in the process of a multi-year ERP system implementation. As the ERP system implementation progresses, our Company may change our processes and procedures which, in turn, could result in changes to our internal control over financial reporting. As such changes occur, our Company will evaluate quarterly whether such changes materially affect our internal control over financial reporting.
