The following information hereby is added to the existing disclosure:

Since the last Amendment filed on August 27, 2025, the SPT and TMPT disposed of 392,972 net shares of Common Stock beneficially owned by Mr. Tutor.

On March 2, 2026, Ronald N.

The timing, manner and amount of such sales have not been determined at this time. Mr. Tutor noted that such sales are solely for personal reasons and he has a high degree of confidence in the business and future of the Company based on its leadership, backlog, bidding opportunities, cash position, as well as its outlook for revenue and earnings growth in 2026 and beyond, and expected future operating cash generation.

**Item 5. Interest in Securities of the Issuer**
