Sidoti's Year End Virtual Investor Conference summary11 Dec, 2025

Company overview and business model

  • Operates with 21,000 employees, focusing on mechanical and electrical installation and service across the U.S.; 85% of business is construction, 15% is service.

  • Mechanical work (HVAC, piping, plumbing) makes up about three-quarters of business, with electrical at one-quarter, reflecting a recent expansion into electrical since 2019.

  • End markets are 65% industrial (data centers, chip manufacturing, food processing), 24% institutional (healthcare, education, government), and 13% commercial.

  • Capital-light model with only 2% of revenue spent on CapEx; 75% of free cash flow is used for acquisitions, the rest for dividends and share buybacks.

  • Focuses on assembling a skilled workforce and deploying cash flow to maximize shareholder value.

Market demand and project pipeline

  • Experiencing a robust project pipeline and record-high backlog of $9.4 billion, especially in technology-driven sectors like data centers and chip manufacturing.

  • Strong demand in pharmaceuticals, life sciences, food processing, and healthcare; largest current contract is a pharma project related to GLP-1.

  • Project selection prioritizes quality, safety, and favorable contract terms, with the ability to turn down less attractive work.

  • Data center projects are denser and more complex, requiring more work per square foot than in the past.

  • Healthcare and education markets remain strong, while commercial construction is weaker but still contributes through service operations.

Strategic initiatives and technology integration

  • Acquired Kodiak to supplement workforce flexibility with traveling labor, addressing surges in demand.

  • Acquired Pivot for its tech stack, enabling better use of AI tools in recruiting and workforce management.

  • Actively integrating AI tools across the organization to drive productivity and efficiency, leveraging scale to share best practices.

  • Modular capacity is expanding, with plans to reach 3 million sq ft by early 2026; further expansion depends on customer commitments and workforce availability.

  • Internal AI adoption is expected to take years to fully realize benefits, similar to past technology shifts.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
