J.B. Hunt Transport Services Inc.: 10-K Risk Factor Changes

We rely on information technology throughout all areas of our business to initiate, track, and complete customer orders; process financial and nonfinancial data; compile results of operations for internal and external reporting; and achieve operating efficiencies and growth. We have also invested significantly in the development of our Marketplace for J.B. Hunt 360 online freight matching platform. Each of our information technology systems may be susceptible to various interruptions, including equipment or network failures, failed upgrades or replacement of software, user error, power outages, natural disasters, cyber-attacks, theft or misuse of data, terrorist attacks, computer viruses, hackers, or other security breaches. We have in the past experienced security breaches and other interruptions of our information technology systems and may in the future experience such breaches or interruptions despite our best efforts to prevent them. We have mitigated our exposure to these risks through the establishment and maintenance of technology security programs and disaster recovery plans, but these mitigating activities may not be sufficient. A significant disruption, failure or security breach in our information technology systems could have a material adverse effect on our business, which could include operational disruptions, loss of confidential information, external reporting delays or errors, legal claims, or damage to our business reputation. We also could experience an inability to keep pace with technological advances, resulting in our information technology platforms becoming obsolete or our competitors developing related or similar service offerings more effective than ours.

Our operations can be heavily impacted by the effects of a widespread outbreak of contagious disease. The effects of a pandemic may disrupt or restrict the freight shipping activities of some of our customers, on which our business is dependent. In addition, adverse economic conditions caused by a pandemic may also require us to increase our reserve for bad debt losses. Furthermore, pandemic related social and economic disruptions may lead to other events which could negatively impact our operations including service limitations of our third-party purchased transportation providers, reduced availability of drivers and other key employees, disruptions in the procurement of revenue equipment, restrictions at U.S. ports of call, excess capacity or rate reductions within the intermodal or trucking industries, inability of suppliers to continue activities, or volatile financial credit markets. The extent to which a pandemic will impact general economic and business conditions is highly uncertain and unpredictable; however, any of these factors could have a significant adverse effect on our financial condition and results of operations.

Our operations can be heavily impacted by the effects of a widespread outbreak of contagious disease, principally the recent outbreak of the COVID-19 virus. The effects of the COVID-19 pandemic have and may continue to disrupt or restrict the freight shipping activities of some of our customers, on which our business is dependent. In addition, adverse economic conditions caused by COVID-19 may also require us to increase our reserve for bad debt losses. Furthermore, the continuation or resumption of COVID-19 related social and economic disruptions may lead to other events which could negatively impact our operations including service limitations of our third-party purchased transportation providers, reduced availability of drivers and other key employees, disruptions in the procurement of revenue equipment, restrictions at U.S. ports of call, excess capacity or rate reductions within the intermodal or trucking industries, inability of suppliers to continue activities, or volatile financial credit markets. The extent to which the COVID-19 outbreak and any future resurgences will impact general economic and business conditions is highly uncertain and unpredictable; however, any of these factors could have a significant adverse effect on our financial condition and results of operations.

For the calendar year ended December 31, 2023, our top 10 customers, based on revenue, accounted for approximately 36% of our revenue. One customer accounted for approximately 13% of our total revenue for the year ended December 31, 2023. Our JBI, ICS, and JBT segments typically do not have long-term contracts with their customers. While our DCS and FMS segments may involve long-term written contracts, those contracts may contain cancellation clauses, and there is no assurance that our current customers will continue to utilize our services or continue at the same levels. A reduction in or termination of our services by one or more of our major customers could have a material adverse effect on our business and operating results.

Federal and state legislation as well as tax and other regulatory authorities have sought to assert that independent contractors in the transportation service industry are employees rather than independent contractors. Recently issued rulemaking by the U.S. Department of Labor, which takes effect on March 11, 2024, and the laws of several states, including California, apply stricter tests for determining whether an independent contractor should be classified as an employee. We believe we are in compliance with all applicable independent contractor classification requirements. However, it is possible that other federal or state legislation or regulations could be enacted or that various authorities could assert a position that re-classifies independent contractors as employees. If our independent contractors are determined to be properly classified as employees, that determination could materially increase our exposure under a variety of federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, as well as our potential liability for employee benefits. In addition, such changes may be applied retroactively, and if so, we may be required to pay additional amounts to compensate individuals for prior time periods. Any of the above increased costs would adversely affect our business and operating results. 10 10 10 10 10 10 10 10 10 10

Federal and state legislation as well as tax and other regulatory authorities have sought to assert that independent contractors in the transportation service industry are employees rather than independent contractors. An example of such legislation has recently gone into effect in California, although a legal challenge to the law is pending. There can be no assurance that interpretations that support the independent contractor status will not change, that other federal or state legislation will not be enacted or that various authorities will not successfully assert a position that re-classifies independent contractors to be employees. If our independent contractors are determined to be our employees, that determination could materially increase our exposure under a variety of federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, as well as our potential liability for employee benefits. In addition, such changes may be applied retroactively, and if so, we may be required to pay additional amounts to compensate for prior periods.
