On May 15, 2026, the Compensation Committee approved the Eagle Materials Inc. Salaried Incentive Compensation Program (“Eagle Plan”), a copy of which is attached to this Report as Exhibit 10.1 and incorporated herein by reference. Under the terms of the Eagle Plan, a pool of 1.2% of the Company’s operating earnings for fiscal 2027 will be available to pay annual bonuses to participating officers, subject to reduction based on individual performance in fiscal 2027 and the following limitations: (i) if the Company’s operating earnings for fiscal 2027 are less than 50% of budget, then no funds will be available for the corporate bonus pool; and (ii) none of the participants in the program will be able to receive a bonus payment in excess of three times (3X) such participant’s annual base salary. The Compensation Committee also determined the applicable percentage of the bonus pool available for payment of the fiscal 2027 annual incentive bonus to the named executive officers participating in the Eagle Plan (Michael R. Haack, President and Chief Executive Officer, 33.0%; D. Craig Kesler, Executive Vice President - Finance and Administration and Chief Financial Officer, 16.0%; and Matt Newby, Executive Vice President, General Counsel and Secretary, 11.0%).

The Compensation Committee also approved the Eagle Materials Inc. Business Unit Salaried Incentive Compensation Program (“Business Unit Plan”), a copy of which is attached to this Report as Exhibit 10.2 and incorporated herein by reference. Under the terms of the Business Unit Plan, a pool of each of the Company’s participating business unit’s EBITDA will be available to pay annual bonuses to participating officers, subject to reduction based on individual performance in fiscal 2027 and the following limitations: (i) if the participating business unit’s EBITDA for fiscal 2027 is less than 50% of budget, then no funds will be available for that business unit’s pool; and (ii) none of the participants in the program will be able to receive a bonus payment in excess of two times (2X) such participant’s annual base salary. For fiscal 2027, the Compensation Committee set the EBITDA percentage for American Gypsum at 2.00% (“AG Pool”), and for the consolidated cement subsidiaries, at 1.90%, as adjusted with respect to our 50% owned cement joint venture (“Cement Pool”).
