Management’s Report on Internal Control Over Financial Reporting

Our management, including our principal executive and principal financial officers, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d -15(f). Internal control over financial reporting is defined as a process designed by, or under the supervision of, the issuer’s principal executive and principal financial officers, or persons performing similar functions, and effected by the issuer’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on the financial statements.

Our management, under the supervision and with the participation of our principal executive and principal financial officers, has conducted an evaluation of the effectiveness of our internal control over financial reporting, using the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2025.

The scope of our assessment of the effectiveness of our internal control over financial reporting did not include Warren Paving or Papich Construction as we acquired them on August 5, 2025. The tangible assets acquired from Warren Paving and Papich Construction were 17.5% of consolidated assets as of December 31, 2025 and revenues were 4.8% of consolidated revenue during the year ended December 31, 2025. We excluded Warren Paving and Papich Construction from the scope of our assessment in accordance with the Securities and Exchange Commission’s guidance that allows a recently acquired business to be omitted from the scope of the assessment for one year from the date of its acquisition.

PricewaterhouseCoopers LLP, our independent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting as of December 31, 2025. Their report is included in Part IV, Item 15(a) of this Form 10-K under the heading “Report of Independent Registered Public Accounting Firm.”

There were no changes in our internal control over financial reporting during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
