Rooted in Taking Challenges

Primoris Services Corporation (Primoris) has built a reputation for taking on challenges that others will not – setting the bar ever higher for ourselves and our industry with each project.

Our roots go back to 1960 with the founding of ARB, Inc. of Bakersfield, CA a pipeline construction company. ARB met the growing demand for energy infrastructure that accompanied the mid-century oil boom in the west and quickly established the reputation for great quality and reliability. ARB's work and reputation fueled significant growth and laid the foundation for Primoris which is today one of the largest specialty contractors in the country.

Primoris was formed in 2004 as the parent company and is traded on the NYSE under the symbol PRIM.
