What changed when Primoris Services Company went public in 2008 and who controls it today? The reverse merger with RREI Holding Corp. transitioned Primoris from founder-led ARB, Inc. into NASDAQ-listed PRIM, shifting ownership toward institutional investors and public stakeholders.

Primoris, founded in 1960 and now based in Dallas, saw its ownership move from legacy leadership to large institutional holders; as of 2025 it has a market cap near $2.85 billion and revenues above $5.9 billion. See Primoris Services Porter's Five Forces Analysis for strategic context.
