Rotunda Capital Partners acquired KSS in 2022, adding it on as a division to American Equipment Solutions (AES), another Rotunda platform. KSS completed three acquisitions in 2023—Memphis Scale Works, American Scale Company, and American Welding Service—followed by Velcon Filling Systems in 2024. AES then sold the KSS division to Investcorp in November 2025, with KSS’s management retaining an equity stake alongside its new sponsor. Investcorp acquired KSS through its North American Private Equity Fund I LP, which closed in February 2023 with $1.2 billion of capital. In May 2026, KSS launched an employee ownership plan (EOP) that granted equity to full-time workers with at least one year of service. According to KSS, its EOP is the first of its kind in the scales and weighing industry.

“The Strack Scale team has built exactly the kind of business we look to partner with – highly trained technicians, deep customer relationships, and an unwavering commitment to quality and service,” said Mr. Carsten. “We’re proud to welcome them to our platform and to extend our Employee Ownership Plan to their team, so that everyone who helped build Strack Scale can share in what we build together.”
