Knight Transportation (KNX) Risk Factors

We have goodwill and indefinite-lived intangible assets on our balance sheet, which has increased since our U.S. Xpress acquisition. Given our history of acquisitions and growth objectives, our goodwill and intangible assets could grow. We periodically evaluate our goodwill and indefinite-lived intangible assets for impairment. We could recognize impairments in the future, and we may never realize the full value of our intangible assets. If these events occur, our profitability and financial condition will suffer.

We are subject to exposure from variable interest rates, as described in Item 7A of this Annual Report.

There is no assurance that in the future, our business will grow substantially or without volatility, nor can we assure you that we will be able to effectively adapt our management, administrative, and operational systems to respond to any future growth. Furthermore, there is no assurance that our operating margins will not be adversely affected by future changes in and expansion of our business or by changes in economic conditions or that we will be able to sustain or improve our profitability in the future. Furthermore, the continued progression and development of new business offerings are subject to risks, including, but not limited to: - initial unfamiliarity with pricing, service, operational, and liability issues;- the potential need for additional capital, including for terminals and equipment;- customer relationships may be difficult to obtain or retain, or we may have to reduce rates to gain and develop customer relationships;- specialized equipment and information and management systems technology may not be adequately utilized;- insurance and claims may exceed our past experience or estimations; and - we may be unable to recruit and retain qualified personnel and management with requisite experience or knowledge of our logistics services, LTL operations, and other developing service offerings.

This could have negative consequences that include: - increased vulnerability to adverse economic, industry, or competitive developments;- cash flows from operations that are committed to payment of principal and interest, thereby reducing our ability to use cash for our operations, capital expenditures, and future business opportunities;- increased interest rates that would affect our variable rate debt or our ability to utilize appropriate leverage in general;- potential noncompliance with financial covenants, borrowing conditions, and other debt obligations (where applicable);- lack of financing for working capital, capital expenditures, product development, debt service requirements, and general corporate or other purposes;- limits on our flexibility to plan for, or react to, changes in our business, market conditions, or in the economy; and - undertaking cost-saving measures that adversely impact on our ability to grow and our long-term financial position.

The potential physical effects of climate change, such as increased frequency and severity of storms, floods, fires, fog, mist, freezing conditions, sea-level rise and other climate-related events, could cause loss or damage to our equipment or properties, deteriorate or destroy the infrastructure upon which we rely, increase the likelihood of accidents, disrupt fuel supplies, and/or increase our claims liabilities and our cost to obtain insurance coverage, any of which could impair our operations and financial position. Operational impacts, such as the delay or difficulty in delivering freight, could result in loss of revenue, decrease the demand for our services, and harm our reputation. In addition, certain warehouses and loading docks that we frequently utilize and certain of our terminals are in locations susceptible to the impacts of storm-related flooding and sea-level rise, which could result in costs and loss of revenue. We could incur significant costs to improve the climate resiliency of our equipment and properties and otherwise prepare for, respond to, and mitigate such physical effects of climate change. We are not able to accurately predict the materiality of any potential losses or costs associated with the physical effects of climate change. Concern over climate change, including the impact of global warming, has led to significant legislative and regulatory efforts to limit carbon and other greenhouse gas emissions. Emission-related regulatory actions have historically resulted in increased costs related to revenue equipment, diesel fuel, equipment maintenance, and environmental monitoring or reporting requirements, and future legislation, if any, could impose substantial costs that may adversely affect our results of operations. In addition, any such legislation may require changes in our operating practices, impair equipment productivity, or require additional reporting disclosures, and compliance with any such legislation may increase our risk of litigation or governmental investigations or proceedings.

The imposition of additional tariffs or quotas or changes to certain trade agreements, could, among other things, increase the costs of the materials used by our suppliers to produce new revenue equipment or increase the price of fuel. Such cost increases for our revenue equipment suppliers would likely be passed on to us, and to the extent fuel prices increase, we may not be able to fully recover such increases through rate increases or our fuel surcharge program, either of which could have an adverse effect on our business.

We are subject to various environmental laws and regulations. We have instituted programs to monitor and control environmental risks and promote compliance with applicable environmental laws and regulations; however, in the event of any of the following, we could be subject to clean-up costs and liabilities, including substantial fines or penalties or civil and criminal liability, any of which could have a materially adverse effect on our business and results of operations: - we are involved in a spill or other accident involving hazardous substances;- there are releases of hazardous substances we transport;- soil or groundwater contamination is found at our facilities or results from our operations; and - we are found to be in violation of or fail to comply with applicable environmental laws or regulations. Certain of our terminals are located on or near environmental Superfund sites designated by the EPA and/or state environmental authorities. We have not been identified as a potentially responsible party with regard to any such site. Nevertheless, we could be deemed responsible for clean-up costs. In addition, tractors and trailers used in our full truckload and LTL operations are affected by laws and regulations related to air emissions and fuel efficiency. Governmental agencies continue to enact more stringent laws and regulations to reduce engine emissions. These laws and regulations are applicable to engines used in our revenue equipment. We have incurred and continue to incur costs related to the implementation of these more rigorous laws and regulations. Additionally, in certain locations governments have banned or may in the future ban internal combustion engines for some types of vehicles. To the extent these bans affect our revenue equipment, we may be forced to incur substantial expense to retrofit existing engines or make capital expenditures to update our fleet. As a result, our business, results of operations, and financial condition could be negatively affected. As the environmental laws and regulations to which we are subject become more stringent, we may experience increased costs related to compliance, and if such laws and regulations take effect faster than we anticipate or are prepared for, we may experience difficulty complying. In addition, certain environmental laws and regulations may require us to disclose certain metrics or other data related to our operations that have historically been confidential. Failure to comply with these laws and regulations may result in fines or penalties, a decrease in productivity, and other constraints that could impair our financial and operational position and have a negative impact on our stock price and reputation. "Environmental Regulation" in Part I, Item 1 of this Annual Report, provides a discussion of the environmental laws and regulations applicable to our business and operations.

A significant portion of our operating revenue is generated from a number of major customers, the loss of one or more of which could have a materially adverse effect on our business. Refer to Part I, Item 1, "Business" for information regarding our customer concentrations. Aside from our dedicated operations, we generally do not have long-term contractual relationships, rate agreements, or minimum volume guarantees with our customers. There is no assurance any of our customers will continue to utilize our services, renew our existing contracts, continue at the same volume levels, or not seek to modify terms of existing contracts, including rates. 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, financial condition, and results of operations. Retail and discount retail customers account for a substantial portion of our freight. Accordingly, our results may be more susceptible to trends in unemployment and retail sales than carriers that do not have this concentration. In addition, our customers' financial difficulties could negatively impact our results of operations and financial condition, especially if these customers were to delay or default on payments to us. For our multi-year and dedicated contracts, the rates we charge may not remain advantageous. Further, despite the existence of contractual arrangements, certain of our customers may nonetheless engage in competitive bidding processes that could negatively impact our contractual relationship.
