Item 1A. Risk Factors— In addition to the other information included in this report and in our other reports and statements that we file with the SEC, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, which could materially affect our business, financial condition and/or operating results. The risks discussed in our Annual Report on Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Other than the following risk factor, which replaces the risk factor titled "Changes in U.S. international trade relationships, including the imposition of new or higher tariffs, may adversely impact our customers, our industry, and our business," there have been no material changes to the risk factors identified in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10‑K for the year ended December 31, 2024.

Changes in U.S. trade policy and the impact of tariffs may continue to adversely impact our customers, our industry, and our business.

Changes in U.S. trade policy and the impact of tariffs may continue to adversely impact our customers, our industry, and our business. We transport a significant number of shipments that have either been imported into the U.S. or are destined for export from the United States. The U.S. government has made significant changes in U.S. trade policy, including the imposition of a baseline tariff on product imports from almost all countries and the potential for individualized higher tariffs on certain other countries. Certain foreign governments either have taken or are threatening to take retaliatory actions in response. These changes in U.S. trade policy and tariffs have decreased demand for our services and have caused uncertainty and volatility in financial markets. Tariffs or other trade restrictions may lead to continuing uncertainty and volatility in U.S. and global financial and economic conditions, declining consumer confidence, inflation or an economic slowdown. These tariffs or other trade restrictions, including corresponding actions taken by other countries in response to U.S. governmental actions or continuing uncertainty around the timing or scale of tariffs, could continue to decrease demand for our services or could increase the cost to us of equipment, goods and materials used in our business, which could have a material adverse effect on our financial condition, results of operation, liquidity and cash flows.
