MYR GROUP INC.

Disclosure Controls and Procedures

Under the supervision, and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures, as defined under Exchange Act Rules 13a-15(e) and 15d-15(e), as of the end of the period covered by this quarterly report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2026.

We completed our acquisition of Valley on July 1, 2026 and Valley has not yet been included in our assessment of the effectiveness of our internal control over financial reporting. We are currently integrating Valley into our operations, compliance programs and internal control processes. Accordingly, pursuant to the SEC’s general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include Valley.

Changes in Internal Control Over Financial Reporting

During the period covered by this report, there were no changes in our internal control over financial reporting that materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
