MasTec is rated Buy as robust infrastructure demand and the Superior acquisition drive record revenues, profitability, and backlog. I see the Superior acquisition as a catalyst for cross-selling and margin expansion, especially in power delivery and critical facility construction. Despite sector-leading growth, MTZ trades at a significant valuation discount, with FWD PEG at 0.58 and FWD EV/Sales at 1.09x.
MTZ's record backlog and raised 2026 guidance signal strong growth, but negative free cash flow and cash conversion challenges remain key concerns.
Shares of MasTec, Inc. MTZ have lost 34.3% over the past six months compared with the Zacks Building Products - Heavy Construction industry's decline of 19.3%. The stock has also lagged the Zacks Construction sector and the S&P 500 Index, as evidenced by the chart below.
MTZ's EPS growth outlook reflects record backlog, broad infrastructure demand and stronger profitability across key segments.

MasTec benefits from surging data center and infrastructure investments, with total backlogs up 30% YoY and Clean Energy & Infrastructure up 58.2%. MTZ's consolidated book-to-bill ratio of 1.24x signals robust demand, while recurring revenues and multi-year contracts smooth out otherwise lumpy revenue streams. Pipeline Infrastructure drives margin expansion, with a 1.72x book-to-bill and 25% ROA, positioning MTZ for continued profitability as capital allocation shifts toward higher-return segments.
MTZ's $21.4B backlog and AI infrastructure exposure support growth, but weak cash flow, Communications segment softness and premium valuation pose risks.
MTZ's record backlog and AI-linked demand are powering growth, with a raised 2026 outlook and expanding data-center capabilities.
