On October 3, 2023, Trinity Industries, Inc. (the “Company” or “Trinity”) issued a press release announcing that it delivered 4,325 new railcars during the quarter ended September 30, 2023. The press release also stated that the number of deliveries was 685 units less than the Company’s quarterly projection, due to the closing of the U.S.-Mexico border to U.S. bound rail traffic at Eagle Pass, Texas, by the U.S. Customs and Border Protection Agency. In addition, the Company stated that increased state vehicle inspections have resulted in truck traffic congestion, negatively impacting the Company’s supply chain. Continued rail and truck congestion at the border will negatively impact the Company’s deliveries and supply chain until the congestion is resolved.
