Brentwood-based private equity firm Highview Capital purchased Frontier Fire Protection, a 59-year-old fire sprinkler and fire alarm protection services company based in Denver, and which serves four states in the western United States.

Terms of the financial transaction were not disclosed.

The company serves as an established network of general contractor customers across a diverse range of end-markets, including apartment buildings, homes, industrial factories, schools, office buildings, senior housing and retailers.

Frontier recently expanded in Colorado and Utah, and plans to expand further with the Highview Capital capital infusion.

“Frontier Fire has extraordinary potential for strategic acquisitions and expansions into new geographies,” said Ryan McCarthy, founder and senior portfolio manager of Highview Capital, in a statement.

This is the fifth company that Highview, a $500 million private equity firm, has announced since its founding in 2016 – and third in the past year.

Last July, Highview bought Carlsbad, Calif.-based specialized food service distributor Good Source Solutions from Evergreen Pacific Partners, a private equity firm based in Westwood Village.

A year ago, Highview and Chicago-based private equity firm Victory Park Capital backed St. Louis-based American Plastics’ acquisition of Centrex Plastics and Creative Plastic Concepts.

American Plastics is a manufacturer, importer and distributor of consumer storage and commercial cleaning products. Creative Plastic, which is based in Sycamore, Ohio, and sister company Centrex, based in Findlay, Ohio, are high-volume plastic injection-molding manufacturers.
