 management. For certain clients, we provide design-build services through ESPCs for building retrofits. 
 Under ESPC contracts, financing sources provide the funds required to pay us for the upgrades and receive a portion of the client’s energy savings to recoup their investment and generate a return. We generated approximately 42% of our 2024           
 Engineering & Consulting segment revenues from selling Program & Project Management services.                                                                                                                                                             |

Installation & Maintenance Our Installation & Maintenance segment fabricates and installs HVAC systems, process piping and other MEP systems in new and existing industrial, commercial and institutional buildings and provides ongoing preventative and corrective maintenance services for those systems. Our Installation & Maintenance segment has two principal service offerings:

| • |     | Installation & Fabrication. We provide HVAC, electrical, plumbing, process and                                                                                                                                                                        
 control system installations, refurbishments and renovations in technically demanding new and existing buildings. We perform both “design-build” and “plan and specification” (“P&S”) projects. Under design-build                                    
 projects, we provide the design for the project and install it. Under P&S projects, our client is responsible for designing the project and we install it to their specifications. For certain jobs, we also fabricate customized components that are 
 not readily available for purchase from other third-party vendors or provide modular construction services based on a client’s specifications. We generated approximately 79% of our 2024 Installation & Maintenance segment revenues from            
 Installation & Fabrication services.                                                                                                                                                                                                                  |

| • |     | Maintenance & Service. We provide preventative maintenance, emergency                                                                                                                                                                                   
 repair and break-fix services over the life of a building’s mechanical systems. Our services include regular inspections and maintenance to prevent downtime; responding to calls and sending technicians onsite to repair a system failure or          
 malfunction; and other complementary services such as facility energy analysis, automation and optimization, system certification and testing. We typically provide preventative maintenance services under annual or longer-term agreements that range 
 from one to five years. We generated approximately 21% of our 2024 Installation & Maintenance segment revenues from Maintenance & Service work.                                                                                                         |
