Industry Overview - U.S. construction activity is entering a durable expansion phase driven by federal infrastructure spending, grid modernization, energy transition projects, and data-center development [1] - The Infrastructure Investment and Jobs Act (IIJA) allocates approximately $350 billion for federal highway programs and up to $108 billion for public transportation programs from fiscal 2022 to 2026 [1] Company Performance - Sterling Infrastructure reported a 32% revenue growth and a 64% increase in backlog, primarily due to data-center demand [8][10] - MasTec's 18-month backlog reached $16.8 billion, with a more than 100% increase in pipeline infrastructure backlog, and a 22% year-over-year revenue growth [13][14] - EMCOR achieved record revenues of $4.3 billion, a 16.4% increase year over year, with remaining performance obligations (RPOs) rising to $12.6 billion, nearly 29% higher than the previous year [17][18] - Jacobs ended fiscal 2025 with a record consolidated backlog of $23.1 billion, a 5.6% year-over-year increase, and reported nearly 28% growth in adjusted EPS [21][22] Backlog and Financial Indicators - Backlog growth and book-to-bill ratios above 1.0x are critical indicators of forward momentum for construction firms [4] - Sterling Infrastructure's total signed backlog reached $2.6 billion, with E-Infrastructure Solutions backlog nearly doubling to $1.8 billion [10] - MasTec's backlog surged by 21% year over year, reflecting broad-based demand across energy and infrastructure markets [14] - Jacobs' trailing 12-month book-to-bill ratio was 1.1x, indicating strong demand across various infrastructure segments [21] Market Outlook - The sustained demand for engineering-led contractors is driven by multi-year, technically complex projects that are less sensitive to short-term economic volatility [3] - Companies like Sterling Infrastructure, MasTec, EMCOR, and Jacobs are well-positioned to benefit from ongoing infrastructure investments, suggesting structural momentum rather than cyclical [25]
