Lastly, it is not possible to predict the effects of actual or threatened armed conflicts or terrorist attacks, efforts to combat terrorism, military action against any foreign state, heightened security requirements or other related events and the subsequent effects on the economy or on consumer confidence in the United States, or the impact, if any, on our future results of operations.

Previous wording

We derive a significant portion of our revenue from our major customers, the loss of one or more of which could have a materially adverse effect on our business. A significant portion of our revenue is generated from our major customers. For 2024, our top 30 customers, based on revenue excluding fuel surcharges, accounted for approximately 69% of our revenue; our top ten customers accounted for approximately 48% of our revenue; our top five customers accounted for approximately 36% of our revenue; our top two customers accounted for approximately 27% of our revenue; and our largest customer accounted for approximately 20% of our revenue. Generally, other than for our Dedicated operations, we enter into one-year contracts with our major customers, the majority of which do not contain any firm obligations to ship with us. We cannot ensure that, upon expiration of existing contracts, these customers will continue to use our services or that, if they do, they will continue at the same levels. Many of our customers periodically solicit bids from multiple carriers for their shipping needs, and this process may depress freight rates or result in loss of business to our competitors. Some of our customers also operate their own private trucking fleets, and they may decide to transport more of their own freight. A reduction in or termination of our services by one or more of our major customers could have a materially adverse effect on our business and operating results.

Ongoing insurance and claims expenses could significantly affect our earnings. Our future insurance and claims expense might exceed historical levels, which could reduce our earnings. We self-insure for a portion of our claims exposure resulting from workers’ compensation, auto liability, general liability, cargo and property damage claims, as well as employees’ health insurance. We also are responsible for our legal expenses relating to such claims. We reserve currently for anticipated losses and expenses. We periodically evaluate and adjust our claims reserves to reflect our experience. However, ultimate results may differ from our estimates, which could result in losses over our reserved amounts.

Previous wording

We maintain insurance above the amounts for which we self-insure with licensed insurance carriers. Although we believe the aggregate insurance limits should be sufficient to cover reasonably expected claims, it is possible that one or more claims could exceed our aggregate coverage limits. Insurance carriers have significantly raised premiums for trucking companies due, in part, to the increase in the number of nuclear verdicts in trucking accident cases. As a result, our insurance and claims expense has increased. If these expenses increase, or if we experience a claim in excess of our coverage limits, or we experience a claim for which coverage is not provided, results of our operations and financial condition could be materially and adversely affected.

*If demand declines for our used revenue equipment, it could result in decreased equipment sales, resale values and gains on sales of assets.*The market for used revenue equipment is subject to a number of factors, including fluctuations in demand and prices. We do not have any agreements with tractor manufacturers pursuant to which they agree to repurchase our tractors or guarantee a residual value. As such, we are sensitive to changes in used equipment prices and demand, especially with respect to tractors. Reduced demand for used equipment could result in a lower volume of sales or lower sales prices, either of which could negatively affect our gains on sales of assets.

Previous wording

*We may be adversely affected by the physical effects of climate change as well as legal, regulatory or market responses to climate change concerns.*Risks associated with climate change are subject to increasing societal, regulatory and political focus. Shifts in weather patterns caused by climate change may lead to an increase in the frequency, severity or duration of certain adverse weather conditions and natural disasters, such as hurricanes, tornadoes, earthquakes, wildfires, droughts, extreme temperatures or flooding, which could cause more significant business interruptions, damage to our revenue equipment and facilities, reduced workforce availability, increased costs, increased liabilities and decreased revenue than what we have experienced in the past from such events. For example, severe sustained heat in multiple regions of the United States during the summer of 2023 resulted in increased fuel expense due to decreased engine fuel efficiency and increased idling, along with additional damage and wear on tires. In addition, increased public and political concern over climate change could result in new legal or regulatory requirements designed to mitigate the effects of climate change and greenhouse gas emissions such as carbon dioxide, a by-product of burning fossil fuels such as those used in our tractors and in the refrigeration units on our trailers and containers, which could include the adoption of more stringent environmental laws and regulations or stricter enforcement of existing laws and regulations. Due to such increased concerns, there could be an increase in regulation from federal, state and local governments related to our carbon footprint, including with respect to vehicle engine emissions. This increase in regulation could result in increased direct costs, such as taxes, fees, fuel, or capital costs, or changes to our operations in order to comply. There is also a focus from regulators and our customers on sustainability issues. This focus may result in new legislation or customer requirements, such as limits on vehicle weight and size or energy source. The State of California recently passed the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act that will impose broad climate-related disclosure obligations on certain companies doing business in California, including us, starting in 2026. Additionally, on March 6, 2024, the SEC adopted climate-related disclosure rules, which could increase compliance burdens and associated regulatory costs and complexity. Following a number of petitions for review filed against the SEC, on April 4, 2024, the SEC issued an order staying the rules pending judicial review. Costs associated with future climate change concerns or environmental laws and regulations and sustainability requirements could have a material adverse effect on our operations and operating results.

In October 2023, the State of California passed the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act that will impose broad climate-related disclosure obligations on certain companies doing business in California, including us. Following legal challenges and due to a high volume of public comments, the California Air Resources Board, has delayed issuing draft regulations pursuant to these laws until the first quarter of 2026. Additionally, on March 6, 2024, the SEC adopted climate-related disclosure rules which became the subject of a number of legal challenges. On March 27, 2025 the SEC voted to end its defense of the proposed rules, though the rules have not been formally withdrawn. While we are continuing to monitor the evolution of these rules, it is difficult to predict when and to what extent they may impact us. Costs…

*We are subject to risks associated with public health crises, such as pandemics and epidemics, which could negatively impact our business and results of operations.*Our operations are subject to risks related to pandemics, epidemics or other infectious disease outbreaks and government responses thereto. COVID-19, which was initially declared a pandemic by the World Health Organization on March 11, 2020 and was declared no longer a global health emergency on May 5, 2023, negatively affected economic conditions, supply chains, labor markets and demand for certain shipped goods.

The COVID-19 pandemic, for example, negatively affected economic conditions, supply chains, labor markets and demand for certain shipped goods.

Previous wording

The extent to which our business, results of operations and financial condition may be negatively affected by the COVID-19 pandemic or future pandemics, epidemics or other outbreaks of infectious diseases is highly uncertain and will depend on numerous evolving factors that we cannot predict, including, but not limited to (i) the duration and severity of the infectious disease outbreak; (ii) the imposition of restrictive measures to combat the outbreak and slow disease transmission; (iii) the introduction of financial support measures to reduce the impact of the outbreak on the economy; (iv) volatility in the demand for and price of oil and gas; (v) shortages or reductions in the supply of essential goods, services or labor; and (vi) fluctuations in general economic or financial conditions tied to the outbreak, such as a sharp increase in interest rates or reduction in the availability of credit. We cannot predict the effect that an outbreak of a new COVID-19 variant or strain, or any future infectious disease outbreak, pandemic or epidemic may have on our business, results of operations and financial condition, which could be material and adverse.

The conflict between Russia and Ukraine, the conflict between Israel and Hamas, and the expansion of such conflicts to other areas or countries or similar conflicts could adversely impact our business and financial results. Although we do not have any operations outside of North America, we may be affected by the broader consequences of the ongoing international conflicts or expansion of such conflicts to other areas or countries or similar conflicts elsewhere, such as, increased inflation, supply chain issues, including access to parts for our revenue equipment, embargoes, geopolitical shift, access to diesel fuel, higher energy prices, potential retaliatory action by the Russian or other governments and the extent of the conflict’s effect on the global economy. The magnitude of these risks cannot be predicted, including the extent to which these conflicts may heighten other risks disclosed herein. Any of the above-mentioned factors could materially adversely affect our business and financial results.

The DOT, through the Federal Motor Carrier Safety Administration, or FMCSA, imposes safety and fitness regulations on us and our drivers. In December 2010, the FMCSA introduced the Compliance, Safety, Accountability, or CSA, system to measure and evaluate the on-road safety performance of commercial carriers and individual drivers. CSA’s Motor Carrier Safety Measurement System replaced the former SafeStat system and has removed a number of drivers from the industry as carriers are less willing to hire and retain drivers with marginal ratings, which has increased competition for qualified drivers. The FMCSA is currently putting in place changes to generally simplify the agency’s safety and fitness regulations.

Previous wording

The FMCSA has established a Commercial Driver’s License Drug and Alcohol Clearinghouse, which is a database of drivers who have violations including failed or refused drug and alcohol tests. Beginning in January 2020, all carriers are required to run queries in the clearinghouse for all prospective drivers and annually for all drivers currently employed. All testing violations must also be reported to the clearinghouse. Additionally, effective November 2024, all states are required to check the clearinghouse for any prohibitions before issuing, renewing, transferring or upgrading any commercial drivers’ licenses. Also effective in January 2020, all carriers must perform random drug tests at a rate of at least 50% of the average number of driver positions. The rate was at least 25% previously. We have been testing at a rate in excess of 50%, including when the requirement was at least 25%, and tested 57% in 2022, 67% in 2023 and 74% in 2024. The impact of the clearinghouse has been significant, with a total of approximately 181,000 drivers removed from the trucking industry from January 2020 through December 2024.

Our business is subject to the risk of litigation, which may adversely affect our business and operating results. We are subject to litigation resulting from trucking accidents. These lawsuits have resulted, and may result in the future, in the payment of substantial settlements or damages and could impact our insurance costs. In particular, the trucking industry has seen a trend of nuclear verdicts, resulting in the payment of substantial damages for claims related to trucking accidents. Additionally, a number of trucking companies, including us, have been subject to lawsuits alleging violations of various federal and state wage and hour laws. A number of these lawsuits have resulted in the payment of substantial settlements or damages by the defendants.

A number of these lawsuits have resulted in the payment of substantial settlements or damages by the defendants.

Previous wording

The outcome of litigation, particularly class action lawsuits, is difficult to assess or quantify, and the magnitude of the potential loss relating to such lawsuits may remain unknown for substantial periods of time. The cost to defend litigation may also be significant. Not all claims are covered by our insurance, and there can be no assurance that our coverage limits will be adequate to cover all amounts in dispute. To the extent we experience claims that are uninsured, exceed our coverage limits or cause increases in future premiums, the resulting expense could have a materially adverse effect on our business and operating results.

If we are unable to retain our executive officers and key management employees, our business, financial condition and results of operations could be *adversely affected.*We are highly dependent upon the services of our executive officers and key management employees, including our Chief Executive Officer. Currently, we do not have employment agreements with these employees and the loss of their services for any reason could have a materially adverse effect on our operations and future profitability. We have entered into agreements with our executive officers that require us to provide compensation to them in the event of termination of their employment without cause in connection with or within a certain period of time after a “change in control” of our Company. In addition, we must continue to develop and retain a core group of managers if we are to realize our goal of expanding our operations and continuing our growth. While our Board regularly engages in succession planning for our Chief Executive Officer and executive leadership team, there is no guarantee that a candidate or plan will be successful. Although we strive to reduce the potential negative impact of any such changes, the loss of any executive officers or key management employees could result in disruptions to our operations. In addition, hiring, training and successfully integrating replacement personnel, whether internal or external, could be time consuming, may cause additional disruptions to our operations and may be unsuccessful, which could negatively impact our business, financial condition and results of operations.
