DIRTT Announces Executive Leadership Changes

DIRTT (“DIRTT”, the “Company”, “we”, “our”, “us” or “ours”) (TSX: DRT; OTCQX: DRTTF), a leader in industrialized construction, today announced two updates to its executive leadership team. Rich Hunter, President and Chief Operating Officer, has departed from the Company and Aaron Merkin has joined the Company in a new Chief Technology Officer position, both effective January 12, 2026.

“Rich joined DIRTT at a pivotal moment and was instrumental in the turnaround of our manufacturing processes, including significant safety improvements and reduction of defects,” said Benjamin Urban, CEO of DIRTT. “We wish him the absolute best in this next chapter.”

DIRTT has also welcomed Merkin to the executive leadership team in a newly created Chief Technology Officer role. Since the Company’s inception, technology has been at the center of innovation, manufacturing excellence, and competitive advantages. Merkin brings extensive technology leadership experience spanning private equity-backed ventures to Fortune 500 corporations. With specific expertise in leading growth-focused transformation in legacy environments, he will focus on advancing DIRTT’s technology to both optimize business operations and deliver increased value to customers. Merkin was most recently Chief Technology Officer at Fortive, a global industrial technology leader, and has worked at companies including IBM, Dell, and Honeywell.

“DIRTT was founded as and remains a technology-enabled manufacturer, which sets us apart from competition,” said Urban. “It is my pleasure to welcome Aaron to this newly created executive role that will ensure DIRTT’s technology continues to lead the industry and drive significant growth for our business.”
