Item 4. CONTROLS AND PROCEDURES

| CONTROLS AND PROCEDURES | | |

DISCLOSURE CONTROLS AND PROCEDURES

We maintain a system of controls and procedures designed to ensure that information required to be disclosed in reports we file with the SEC is recorded, processed, summarized and reported within the time periods specified by the SEC's rules and forms. These disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a - 15(e) or 15d - 15(e)), include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Our Chief Executive Officer and Chief Financial Officer, with the participation of other management officials, evaluated the effectiveness of the design and operation of the disclosure controls and procedures as of June 30, 2024. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2024.

We are in the process of replacing our quote to invoice system for our aggregates and asphalt operations and expect the full implementation of this system to be completed by the fourth quarter of 2024.

No other changes were made during the second quarter of 2024 to our internal controls over financial reporting, nor have there been other factors that materially affect these controls.
