Green Brick Partners, Inc.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer ( “CEO”) and principal financial officer (“CFO”), we conducted an evaluation of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of September 30, 2025 in providing reasonable assurance that information required to be disclosed in the reports we file, furnish, submit or otherwise provide to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that information required to be disclosed in reports filed by us under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, in such a manner as to allow timely decisions regarding the required disclosures.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2025, there were no changes in our internal controls that have materially affected or are reasonably likely to have a material effect on our internal control over financial reporting.
