Millrose Properties, Inc.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (“Exchange Act”)) as of the end of the period covered by this Form 10-Q as required by paragraph (b) of Rule 13a-15 or 15d-15 of the Exchange Act. Based upon such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2026 and provided reasonable assurance that information required to be disclosed by us in the reports 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.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) that occurred during the quarter ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Prior to the Spin-Off, the Predecessor Millrose Business relied on processes and internal controls over financial reporting performed by Lennar. After the Spin-Off, Millrose became an independent company and responsibility for these processes and controls were transferred to KL, the Manager for Millrose. These changes are not expected to materially affect or have an adverse impact on our ability to maintain adequate internal controls over financial reporting. Following the Spin-Off, new corporate and governance functions were and continue to be implemented in order to meet the regulatory requirements of a stand-alone company.
