dycomDycom Industries, the publicly traded telecommunications contractor, has enlisted Kekst and Company in its breach of contract suit against Quanta Services, after Dycom bought Quanta subsidiaries for $300M.

Florida-based Dycom alleges Quanta has violated the 2012 stock purchase agreement by, among other acts, soliciting business in competition with Dycom as well as employees of Dycom. Dycom filed the suit March 31 in federal court and amended to complaint this week.

"When we buy a business we expect the sellers to honor their obligations," Dycom president and CEO Steven Nielsen said in a statement, noting his company raised the issues with Quanta, and was rebuffed, before filing suit.

Kekst managing directors Mark Semer, Daniel Yunger and Rachel Posner represent Dycom on the PR front.

Dycom went public with its amended complaint on May 5, the same day Quanta released first quarter earnings ($1.7B revenues, $20.5M net income).

Quanta has not publicly responded to the litigation. Texas-based PR firm Ward supports its communications.
