 health care end-markets. As of September 30, 2025, we had $3.1 billion of backlog and awarded contracts, representing an increase of 29% over the same date last year.

We specialize in designing, fabricating and installing complex HVAC, process piping and other mechanical, electrical and plumbing
(“MEP”) systems for new facilities and upgrading HVAC, lighting and building controls in existing facilities to make them more energy efficient and sustainable. In 2024, we generated 32.5% of our revenues from new building projects and
67.5% of our revenues from retrofits, upgrades and maintenance for existing buildings. Our team includes approximately 1,200 MEP engineers and energy consultants, and approximately 3,800 technicians and craftspeople, including HVAC and plumbing
service technicians, fitters, electricians and sheet metal workers, of which approximately 570 are responsible for providing maintenance services to over 5,900 clients. We completed more than 50,000 jobs each year for clients across the United
States during the period from 2021 through 2024.

We operate through two complementary segments: Engineering & Consulting and
Installation & Maintenance. Our Engineering & Consulting segment designs HVAC and other MEP systems for buildings, develops strategies to help reduce energy usage and make buildings more sustainable and provides program and project
management services for clients’ installation and retrofit projects. From 2021 to 2024, our Engineering & Consulting segment revenues grew at a compound annual growth rate of approximately 83% and, after giving pro forma effect to
acquisitions we made over that period, approximately 15%. We have completed over 30,000 jobs in our Engineering & Consulting segment since 2019. Our Engineering & Consulting segment generated 28.7% and 47.6% of our revenues and
gross profit, respectively, in 2024.

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

to annual or multi-year contracts. From 2021 to 2024, our Installation & Maintenance segment revenues grew at a compound annual growth
