Brookside Mezzanine Partners is pleased to announce a successful exit from its investment in Surface Preparation Technologies, LLC (“SPT”), a portfolio company of Brookside Mezzanine Fund III, L.P. SPT is the nation’s leading provider of rumble strips and related roadway safety services to state and local governments. Since 1988, it has installed over 175,000 miles of rumble strips and is the only rumble strip provider with the ability to cover the entire United States.

In February 2017, Brookside Mezzanine Partners provided subordinated debt and an equity co-investment to support the acquisition of SPT by Branford Castle Partners, L.P., a New York City-based private equity firm that invests in lower middle-market companies.

“Brookside Mezzanine Partners was, once again, an important financing partner for us and their support helped fuel the growth of SPT” said Eric Korsten, Senior Managing Director of Branford Castle.

“We are delighted to have been selected by Branford Castle and have the opportunity to work with them and the management team of SPT to achieve the growth that we have accomplished together over the last two and one-half years,” said Gregory Foy, Partner of Brookside Mezzanine Partners. “This investment was an attractive outcome for our limited partners, and we wish the team of SPT further success as they continue to execute their growth strategy.”
