ATLANTA, Nov. 30, 2021 /PRNewswire/ — Mammoth Holdings, LLC (“Mammoth”), an Atlanta-based conveyor car wash operator, announced that Silverstar Car Wash (“Silverstar”), a fourteen-unit car wash operator with operations in South Dakota, North Dakota, Iowa, and Nebraska, has agreed to join the Mammoth organization. Silverstar’s ownership group made a significant equity investment in Mammoth.

Dave Hoffmann, Mammoth’s Chairman and CEO, explained, “The Silverstar team are world-class operators and have quickly built an impressive footprint in the Sioux Falls and Sioux City markets.” He added, “Silverstar has taken a unique approach to development that we will continue to leverage across our operator-led platform, in addition to learning from their best-in-class operations.”

Bryan Slama, Silverstar’s founder, stated, “It was very important to pick a partner who shared our values and our vision for the industry. After meeting Dave [Hoffmann] and the Mammoth team, we immediately knew these were the people we wanted to grow our business with.” He added, “Mammoth puts people first, and we are excited to be able to provide our employees an opportunity to grow their careers within a larger organization.”

Mammoth is the first car wash platform formed by industry-insiders and is the 6th largest conveyor car wash operator in the United States according to Commercial Plus’s Top 100 list. Mammoth is customer-focused operationally and operator-focused in its approach to partnerships and acquisitions and seeks to be the partner-of-choice for car wash operators who desire liquidity, growth capital, and a tax-deferred equity investment opportunity. Mammoth’s multi-brand portfolio includes Marc-1, Wash Me Fast, Swifty, Ultra, Finish Line, Wiggy Wash, Shine On, Pit Stop, Lulu’s, Ollie’s, PureMagic, Busy Bee, and now Silverstar among others. Mammoth has significant growth capital at its disposal and is actively seeking acquisitions and development opportunities.

In October 2018, Mammoth partnered with Red Dog Equity LLC, an Atlanta-based private equity firm, which, through its partnership with Tom Pritzker’s family business interests (advised by The Pritzker Organization), provides the equity for Mammoth’s corporate development initiatives. Monroe Capital and Morgan Stanley provide Mammoth’s debt financing.
