Woodcliff Lake-based PKF Investment Banking has closed the sale of Armistead Mechanical to PremiStar, a portfolio company of private equity firm Partners Group USA Corporation.
Founded in 1917, Armistead Mechanical provides mechanical construction and contracting services to industrial and commercial clients throughout the New Jersey/New York area. With an office in Waldwick, the company specializes in industrial and process piping, fabrication and installation, plumbing, HVAC design and installation, temperature controls, and preventive maintenance services for projects of all sizes.
Alberto Sinesi, Partner at PKF Investment Banking, led the transaction. Sinesi was named partner in February.
PremiStar, formerly Reedy Industries, and its more than 3,000 employees operate 61 commercial HVAC, building automation, and plumbing branches across 18 states.
PremiStar supports owners and managers of critical facilities in the commercial, municipal, educational, and industrial markets by helping them create healthier, more cost-effective, and more energy-efficient environments.
PKF is the investment banking affiliate and subsidiary of PKF O’Connor Davies, one of the nation’s largest accounting, tax, and advisory practices.
In January, PKF Investment Banking sold a premier residential property management company to one of the nation’s largest integrated platforms for Homeowners Associations (HOAs).
