Legence Corp. helps building owners and operators equip new facilities and upgrade existing ones with heating, cooling, electrical, plumbing and process-piping systems. It can design the systems and manage the project before fabricating and installing equipment, then provide preventive maintenance and repairs. Owners and operators pay Legence directly, or architects and general contractors hire it for the building-systems portion of a larger project.
Fabrication and installation generate most revenue; engineering, consulting and maintenance provide the rest. Work on existing buildings contributes more revenue than new construction. Data centers and technology are its largest customer market, followed by life sciences and healthcare, and education.
Most contracts set a fixed price, so profitability depends on estimating and controlling labor, equipment, material and subcontractor costs. Most work outside maintenance is one-time, making continued contract wins important. Demand also depends on clients funding and proceeding with construction and upgrade projects, which must meet applicable permitting, environmental and safety requirements.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Legence’s results hinge on investment in mission-critical buildings and retrofit budgets, with privately held ACCO Engineered Systems and Southland Industries also worth watching as national installation and maintenance rivals.
Comfort Systems USA and Legence compete for customers paying to design, install and maintain building heating, cooling, electrical and plumbing systems, so technology-facility spending matters to both. Watch Comfort Systems’ technology revenue: it supplied 45% of revenue in 2025, while data centers and technology supplied roughly 43% of Legence’s.
EMCOR and Legence compete for building and industrial customers’ spending on designing, installing and maintaining heating, cooling, electrical, plumbing, piping and control systems. EMCOR’s U.S. electrical and mechanical construction and facilities-services revenue is the part to watch for demand overlapping with Legence’s work.
Limbach Holdings and Legence both rely heavily on existing-building budgets, combining engineering with installation and maintenance of mechanical, electrical and plumbing systems for owners and operators. Watch Limbach’s work sold directly to owners, primarily for existing buildings: it generated 75.1% of 2025 revenue, while existing-building work supplied 60.3% of Legence’s revenue.
Everus Construction Group competes with Legence for electrical and mechanical construction and maintenance work paid for by general contractors and end customers. Focus on Everus’s Electrical & Mechanical segment, which supplied approximately 77% of total contract revenue in 2025 and serves commercial, industrial and institutional markets, among others.
IES Holdings and Legence share exposure to data-center and commercial-facility spending because both design, install and maintain facility electrical and mechanical systems. Watch IES’s Communications business with global technology, social-networking and e-commerce customers rather than treating its residential revenue as a read on Legence.
Sterling Infrastructure competes with Legence’s installation work through its E-Infrastructure business, which provides critical electrical and mechanical services for data-center and manufacturing customers. Watch that business’s data-center and manufacturing work, rather than Sterling’s road or residential-concrete projects, for the closer read on Legence’s demand.
Johnson Controls and Legence compete for commercial customers’ HVAC installation, servicing, building controls and energy-efficiency budgets. Johnson Controls’ repeat maintenance, retrofit and replacement business from existing customers is the useful part to watch for spending on buildings already in use.
MYR Group overlaps with Legence where commercial and industrial customers pay for electrical installation, upgrades, maintenance and repairs. Its Commercial & Industrial business is the relevant comparison, not its separate work on utility transmission and distribution networks.
Stantec competes with Legence’s Engineering & Consulting segment for customers’ building-design and project-management budgets. Watch Stantec’s Buildings work for public- and private-sector clients, where its engineering and design services overlap most directly with Legence’s building-system designs and retrofit project management.
Ameresco competes with Legence’s CMTA business for customers’ energy-efficiency upgrades, including projects where financing sources fund the work and recover their investment and return from a share of energy savings—energy savings performance contracts. Watch Ameresco’s facility-upgrade projects using this financing for a read on the same upgrade funding available to Legence.
Vertiv and Legence both depend on data-center cooling and power investment: Vertiv sells the systems, while Legence designs and installs the facilities’ building infrastructure. Watch Vertiv’s air- and liquid-cooling and power-system sales for demand related to the facilities Legence serves.
Trane Technologies competes with Legence for commercial customers’ HVAC maintenance, building-control and energy-efficiency spending, while also making and selling HVAC equipment. Watch Trane’s commercial HVAC services and energy solutions rather than its residential heating or transport refrigeration business.
nVent and Legence share exposure to technology-facility investment: nVent sells data-center cooling and power-distribution systems, while Legence engineers and installs mechanical and electrical infrastructure. Watch nVent’s Systems Protection cooling and power-distribution business, whose customers include hyperscalers and contractors.
ABM Industries competes with Legence for customers’ HVAC, mechanical, electrical and energy-efficiency work, but its large nontechnical facilities-services business makes the overall company a less direct comparison. Watch ABM’s Technical Solutions business rather than its cleaning, parking or landscaping services for the overlap with Legence.
Comfort Systems USA, Inc. earningsFIX
Comfort Systems' technology revenue will show whether data-center and other technology-facility customers are still funding building-systems work in a market that matters to Legence.
Watch the change in Comfort Systems' technology revenue in the context of Legence's data-center and technology market, which accounted for 42.7% of Legence's 2025 revenue. Stronger technology revenue would indicate that the shared technology-facility market is still supporting building-systems projects; weaker revenue would signal that customer demand may be softening. The companies define these categories differently, so this is not a like-for-like comparison. The point is whether spending in a market Legence serves is holding up.
Limbach Holdings, Inc earningsLMB
Limbach's revenue from owner-direct work, primarily in existing buildings, will show whether building owners are still paying for upgrades, installation and maintenance; existing buildings account for 60.3% of Legence's revenue.
Watch Limbach's revenue from work sold directly to owners, primarily for existing buildings. If it strengthens, owners are still commissioning work in buildings already in use, supporting the demand picture for Legence's existing-building business; if it weakens, owners may be delaying or scaling back projects. This work generated 75.1% of Limbach's 2025 revenue, while existing buildings accounted for 60.3% of Legence's revenue; the categories are not identical. The key is the direction of owners' spending.
Ameresco, Inc. earningsAMRC
Ameresco's upgrades funded through energy savings performance contracts will show whether customers are still using outside financing for building improvements, a model Legence also uses for some projects.
Watch whether Ameresco's facility upgrades financed through energy savings performance contracts continue to move ahead. A financing source pays for the upgrades and recoups its investment and return from a share of the customer's energy savings. More activity would suggest customers and funders still accept a model Legence also uses for some retrofits; less activity could mean financing terms or expected savings are no longer enough to support projects. The takeaway is whether this funding route is still supporting building upgrades.
Stantec, Inc. earningsSTN
Revenue from Stantec's Buildings business will show whether customers are still funding building design, the kind of budget Legence's Engineering & Consulting segment also competes for.
Watch revenue from Stantec's Buildings work for public- and private-sector clients, and compare its direction with Legence's Engineering & Consulting revenue. Stronger Buildings activity would show that customers are still funding design and project management, supporting the budget pool Legence competes for; weaker activity would suggest customers are tightening building-design spending. Legence's segment also covers building-system design and project management, so the conclusion is whether that customer budget remains available.
Legence Corp. earningsThis company
Legence's installation and maintenance business brings in most of its revenue, and this report will show whether that project growth is producing better gross margins.
Read Installation & Maintenance revenue alongside its gross margin—the share of revenue left after direct project costs. If both rise, Legence is taking on more work while keeping labor, materials and cost estimates under control; if revenue rises but margin falls, project costs are taking a larger bite from that growth. Check Engineering & Consulting revenue and margin too, to see whether design and project-management work is improving as well. The conclusion is whether growth is translating into stronger project economics.
