Insider trading arrangements and policies

During the three months ended March 31, 2025, no director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

Long-term Incentive Plan

On March 1, 2025, the Company adopted a long-term incentive plan (“LTIP”) in order to provide additional alignment between the Company’s Executive Officers and its stockholders. The LTIP provides that certain executive officers receive Restricted Stock Units (“RSUs”) and Performance Stock Units (“PSUs”) based on the Company’s (i) TSR performance and (ii) Return on Assets over the three-year period commencing on January 1, 2025 and ending on December 31, 2027 unless earlier terminated due to a Change in Control (as defined in the LTIP). The Compensation committee granted each of James R. Brickman, the Company’s Chief Executive Officer, Jed Dolson, the Company’s Chief Operating Officer, Neal Suit, the Company’s General Counsel and Chief Risk and Compliance Officer, and Bobby Samuel, the Company’s Executive Vice President of Land, an LTIP award, in each case, under the Company’s 2024 Omnibus Incentive Plan (as amended, the “Plan”) and, in connection therewith, entered into an RSU/PSU Award Agreement (each an “Agreement” and collectively, the “Agreements”), which Agreements establish the terms and conditions of those awards, including the performance period and the applicable performance measures to be used in determining whether and to what extent, if any, the award is earned and amounts payable thereunder, if any.

Annual Incentive Plan

On February 12, 2025, the Company amended the Annual Incentive Plan (“AIP”) in order to remove EPS Performance as a performance metric. All other material terms of the AIP remained unchanged.
