In August 2024, Legence, a Blackstone Portfolio Company and North America’s leading integrated provider of energy efficiency and sustainability solutions for the built environment, acquired AMA Group, a New York City-based national engineering services firm. AMA Group is integrating with CMTA, Legence’s largest mechanical, electrical, and plumbing (MEP) engineering services portfolio company. This collaboration marks a significant milestone in creating a unified team, dedicated to advancing resiliency in the built environment. AMA Group brands are currently operating under a combined AMA/CMTA logo and by Fall 2025, AMA Group’s six companies will be fully operating as CMTA.
As one of the only firms in the U.S. that delivers MEP engineering, performance contracting, and zero energy/zero carbon solutions, CMTA designs high-performance facilities that reduce utility costs, improve resiliency, and enhance the health and wellness of communities. Similarly, AMA Group brings a wealth of experience to the table, providing innovative, cost-effective, and solution-focused engineering designs in a wide range of markets.
In addition to enhancing Legence and CMTA’s MEP and technology engineering capabilities, AMA brings new expertise in acoustic, lighting, and immersive audio-visual design.
