MasTec Reports Record Q2 Results, Raises Guidance on Mission-Critical Infrastructure Boom
The infrastructure contractor posted 23% revenue growth and raised full-year targets, citing unprecedented demand from AI data centers and grid modernization.
Record Quarter Across Metrics
MasTec, Inc. (MTZ) delivered second-quarter revenue of $4.374 billion, up 23% year-over-year, the company reported in its July 31 earnings call. Adjusted EBITDA reached $384 million, a 40% increase, while adjusted earnings per share of $2.22 represented 49% growth compared to the prior year (earnings call, 2026-07-31).
The Coral Gables-based infrastructure contractor achieved record backlog of $21.4 billion at quarter end, up nearly $5 billion year-over-year and $1 billion sequentially on an organic basis. The company posted a total book-to-bill ratio above 1.2x (earnings call, 2026-07-31).
"We set new highs across virtually every key financial metric," CEO Jose Mas said on the call. "More importantly, the underlying demand driving these results continues to strengthen" (earnings call, 2026-07-31).
Superior Acquisition Expands Mission-Critical Exposure
The quarter included the close of MasTec's largest acquisition to date: The Superior Group. Mas emphasized that the acquisition positions the company "to lead what we believe will be a generational infrastructure investment cycle driven by AI, electrification and the continued growth of digital infrastructure" (earnings call, 2026-07-31).
The combination enhances MasTec's capabilities in the power delivery segment, where revenue increased nearly 20% year-over-year with EBITDA growth of 24%. Segment backlog rose almost $1.3 billion compared to the prior year, driven by utility spending on transmission, system hardening, and infrastructure to support mission-critical facilities (earnings call, 2026-07-31).
Segment Performance and Communications Headwinds
Clean Energy & Infrastructure posted 43% revenue growth year-over-year, with EBITDA up 54% and sequential backlog growth of $500 million. The Pipeline segment saw revenue increase 19% with EBITDA nearly doubling, while backlog reached its highest level since Q2 2023 (earnings call, 2026-07-31).
The Communications segment faces near-term pressure, however. "While our longer-term outlook in Communications is unchanged, we are experiencing some short-term pressure," Mas acknowledged. Lower wireless revenues in the second half of 2026 and wireline project deferrals are creating headwinds, though the company is pursuing "billions of dollars of opportunities related to" hyperscaler connectivity (earnings call, 2026-07-31).
Raised Guidance Reflects Strong Momentum
MasTec increased its full-year 2026 guidance to revenue of $18.2 billion, adjusted EBITDA of $1.6 billion, and earnings per share of $9.30—representing year-over-year growth of 27%, 39%, and 42%, respectively (earnings call, 2026-07-31).
CFO Paul Dimarco noted that second-quarter adjusted EBITDA margins expanded approximately 100 basis points year-over-year. Power Delivery margins exceeded 9%, while Pipeline Infrastructure margins approached 20%, "reflecting both strong project execution and favorable project mix" (earnings call, 2026-07-31).
Mas emphasized that despite nearly $2.5 billion in backlog growth over the past two quarters, "only a modest portion contributes to 2026 revenue, with the majority expected to benefit 2027," suggesting sustained earnings power ahead (earnings call, 2026-07-31).
