In a research note titled "Buy the Inflection," Citi analyst Andrew Kaplowitz says MasTec remains one of his favorite Engineering & Construction names. Despite visibility across all four of its businesses, MasTec shares continue to trade at a 7% discount to their historical 5-year average, Kaplowitz tells investors in a research note after spending time with management. If the company can prove that the handoff of growth from oil and gas to communications is happening and that cash flow concerns are only timing related, MasTec will be one of the few stories in E&C with both multiple expansion and earnings revision upside, the analyst contends. He keeps a Buy rating on the shares.
