Catalyst Acoustics Group was formed in 2020 and has since enjoyed consistent year-over-year financial growth through an intentional balance of M&A activity and organic focus. A strong leadership team and deep bench of talent has driven Catalyst to a leadership position in the acoustic space. Speaking of the sale, Grant Jones, Managing Director of Stephens Group, called this a “natural evolution,” adding that, “[we] always believed that bringing the Catalyst family of companies together provided an outstanding and unique foundation for further expansion. We are grateful to Joe Lupone, Chief Executive Officer of Catalyst Acoustics Group, and the entire team for their partnership during the last five years. Together, we built a market leader, and Stephens Group is proud of the growth the company experienced under our watch. We are excited to pass the baton to KPS for the next chapter of success.”

Lupone commended both Stephens Group and KPS when speaking of his organization’s past and future. “Each of our brands comes to the table with well-seasoned, robust channel partners and strong value propositions. Stephens Group always understood how critical brand and channel preservation is to our organization, and I am pleased to report that KPS shares this outlook. We look forward to a bright future as part of the KPS family and to providing expanded opportunities to our loyal customers.”

With a closing expected in the fourth quarter of 2024, Catalyst Acoustics Group, its employees, customers, and constituents have a high level of excitement and a very positive outlook for the new year. Additional information on the acquisition will be provided post-close.
