Dycom Industries, Inc.
A specialty contractor that builds and maintains the networks behind modern digital life, Dycom lays fiber-optic cable, builds wireless towers, and — through its newer Building Systems arm — wires data centers and critical facilities. Its customers include telecom giants AT&T, Verizon, and Lumen. Founded in 1969 as Mobile Home Dynamics (yes, a mobile-home installer), it reinvented itself in the 1980s, betting early on fiber optics before that became the industry standard.
