Chairman of the Board and Chief Executive Officer Randolph L. Marten stated, “Our earnings have continued to be significantly pressured by the historic duration and depth of the freight market recession’s oversupply and weak demand -- and the cumulative impact of inflationary operating costs, unacceptable freight rate reductions and freight network disruptions. Our unique multifaceted business model’s value continued to be highlighted by the operating results of our dedicated and brokerage operations for the first nine months of this year and throughout last year.”

“We remain focused on minimizing the freight market’s impact with our emphasis on safe, premium service, data-driven operating efficiencies and cost controls. Our strong, debt-free balance sheet enhances our ability to continue investing in our technology and modern fleet and position our operations to capitalize on future profitable organic growth opportunities. We expect the current administration’s recent immigration enforcement efforts including stricter standards for non-domiciled commercial driver’s licenses and increased enforcement of English Language Proficiency and B-1 visa regulations to positively impact such opportunities.”

“We also closed on the previously announced agreement to sell assets related to our intermodal business to Hub Group, Inc. (NASDAQ: HUBG), effective September 30, 2025. The transaction was structured as an asset sale of certain intermodal equipment, including over 1,200 refrigerated containers, and contracts to Hub Group, Inc. for $51.8 million in cash. This transaction clarifies our focus on investing in and positioning our core operations for future expansion.”
