Baird analyst Andrew Wittmann notes that the Federal Energy Regulatory Commission has allowed the substantial re-start of construction for MasTec's largest pipeline construction project, the Mountain Valley Pipeline. Today's news re-authorized substantially all the construction to resume, except for those crossing federal lands, where an updated environmental review was mandated by a federal appeals court in late July, he points out, adding that he estimates only about 30 miles of pipeline are impacted by the work stoppage at this point. Wittmann reiterates an Outperform rating and $51 price target on the shares.
