NEW YORK–(BUSINESS WIRE)–Blackstone (NYSE: BX) announced today that funds affiliated with Blackstone Energy Transition Partners and other Blackstone funds (“Blackstone”) have acquired Alliance Technical Group (“ATG”), a leading provider of environmental testing, monitoring, and compliance services.

Founded in 2000 and headquartered in Alabama, ATG has grown into one of the largest full-service environmental compliance providers in North America, with more than 2,200 employees located in 60-plus offices and labs across the U.S. and Canada. ATG delivers a comprehensive suite of solutions – including source and lab testing, continuous emission monitoring systems (CEMS), and leak detection and repair, among others – to help businesses maintain regulatory compliance and safety, while driving efficiency through ATG’s data-driven insights.

Chris LeMay, Chief Executive Officer at Alliance Technical Group, said: “Blackstone’s investment is a testament to our strong organic and strategic growth as a trusted market leader in the testing, inspection and compliance sector.

Chris and the ATG management team have built a diversified platform with a strong reputation for technical quality and reliability. Together, we are excited to leverage Blackstone’s scale and resources to help support ATG’s continued growth, serving its existing and new customers across the power, energy and industrial sectors.”
