> Primoris is a specialty contractor delivering engineering, construction and maintenance across utilities, energy, renewables and industrial markets. It executes both project awards and master service work. In 2026 it disclosed cost overruns on six utility-scale solar projects, so company context should distinguish these issues from other business lines and later completion updates.
