Key takeaways: Koch Cos. acquired Store Opening Solutions from Marmon Holdings for an undisclosed sum, strengthening the transportation group's warehousing operations, it said Jan. 12. Murfreesboro, Tenn.-based Store Opening Solutions specializes in retail fixture, furniture and equipment inventory. The company has 97 employees. Store Opening Solutions will become part of Minneapolis-based Koch Cos.' Koch Logistics division. Koch Logistics will now operate more than 3 million square feet of warehousing and storage space following the deal, with facilities in Chicago; Corona, Calif.; and Murfreesboro. Acquiring Store Opening Solutions is set to double the company's warehousing space. SOS's strong client base in the retail industry also contributed to the decision to acquire the company, Koch Cos. said. "Bringing SOS into the Koch Companies family represents a meaningful step in our long-term strategy to strengthen and expand our logistics, fulfillment and trucking capabilities," said Jeff Koch, the parent company's chief operating officer. Koch "By investing in the people, infrastructure and services that define both SOS and Koch, we're positioning the business and our customers for long-term success," he added. Third-generation trucking company Koch has built and maintained an operational team on-site in Murfreesboro since 1999. "Koch Logistics has a 25-year history working alongside SOS, and we are extremely excited about what the future holds as we blend the best of both companies," said Darren Nelson, vice president and general manager of Koch Logistics and Warehousing. "Bringing both entities under the same umbrella, having a shared vision and strategy, will allow us to create synergies and value-added solutions for our clients." The parent company said more acquisitions could be on the slate, particularly in the warehousing and fulfillment arena. Koch Cos.' last acquisition was Logistics Edge in 2021. The company - which is celebrating its 50th year in business in 2026 - has five divisions: Koch Trucking, Koch NationaLease, United Trailer Leasing, Koch Logistics and Koch Maritime. Koch Trucking operates more than 900 trucks and 2,000 trailers. The division specializes in dry van truckload, dedicated, flatbed and drayage operations. The company's tractors are all three years old or newer. Volvo Trucks North America landed an order from Koch Trucking for 185 Volvo VNL 860s in December. The VNL received an overhaul in January 2024. "Maintaining one of the newest fleets in the industry allows us to maximize uptime and deliver consistent, reliable service our customers expect," Jeff Koch said in December. United Trailer Leasing operates more than 3,000 pieces of rolling stock. Ocean freight forwarder Koch Maritime is part of Koch Logistics and provides end-to-end international and ocean/air shipping services. Marmon Holdings is also the parent company of Fontaine Fifth Wheel, Fontaine Modification, Fontaine Trailer, Sisu Axles, Stahl Truck Bodies, Triangle Suspension Systems and TSE Brakes.
