PART I

ITEM 1. BUSINESS

Unless the context requires otherwise, references in this report to “Old Dominion,” the “Company,” “we,” “us” and “our” refer to Old Dominion Freight Line, Inc.

Overview

We are a leading,one of the largest North American less-than-truckload (“LTL”), union-free motor carrier providingcarriers. We provide regional, inter-regional and national LTL services through a single integrated, union-free organization. Our service offerings, which include expedited transportation, are provided through an expansive network of service centers located throughout the continental United States. Through strategic alliances, we also provide LTL services throughout North America. In addition to our core LTL services, we offer a range of value-added services including container drayage, truckload brokerage and supply chain consulting. More than 97%98% of our revenue has historically been derived from transporting LTL shipments for our customers, whose demand for our services is generally tied to industrial production and the overall health of the U.S. domestic economy.

We are the fourth largest LTL motor carrier in the United States, as measured by 2017 revenue, according to Transport Topics. We have increased our revenue and customer base over the past fiveten years primarily through organic market share growth. Our infrastructure allows us to provide next-day and second-day service through each of our regions covering the continental United States. WeIn addition to numerous service center renovations, expansions, and relocations of existing service centers, we opened 147, 25 and 2935 new service centers over the past one, five and ten years, respectively, for a total of 235251 service centers at December 31, 2018.2021. We believe this expansionthese expansions produced increased capacity within our service center network and providesprovide us with opportunities for future growth.

We believe the growth in demand for our services can be attributed to our ability to consistently provide a superior level of customer service at a fair price, which allows our customers to meet their supply chain needs. Our integrated structure allows us to offer our customers consistent, high-quality service from origin to destination, and we believe our operating structure and proprietary information systems enable us to efficiently manage our operating costs. Our services are complemented by our technological capabilities, which we believe provide the tools to improve the efficiency of our operations while also empowering our customers to manage their individual shipping needs.

We were founded in 1934 and incorporated in Virginia in 1950. Our principal executive offices are located at 500 Old Dominion Way, Thomasville, North Carolina 27360.

Our Industry

Trucking companies provide transportation services to virtually every industry operating in the United States and generally offer higher levels of reliability and faster transit times than other surface transportation options. The trucking industry is comprised principally of two types of motor carriers: LTL and truckload. LTL freight carriers typically pick up multiple shipments from multiple customers on a single truck. The LTL freight is then routed through a network of service centers where the freight may be transferred to other trucks with similar destinations. LTL motor carriers generally require a more expansive network of local pickup and delivery (“P&D”) service centers, as well as larger breakbulk, or hub, facilities. In contrast, truckload carriers generally dedicate an entire truck to one customer from origin to destination.

Significant capital is required to create and maintain a network of service centers and a fleet of tractors and trailers. The high fixed costs and capital spending requirements for LTL motor carriers make it difficult for new start-up or small operators to effectively compete with established carriers. In addition, successful LTL motor carriers generally employ, and regularly update, a high level of technology-based systems and processes that provide information to customers and help reduce operating costs.

According to theThe American Trucking Associations the trucking industry accounted for 79.3% of the $883.4 billionreported total U.S. transportation revenue in 2017. Thethe United States of $911.2 billion in 2020, which included approximately $41.1 billion for the LTL sector had revenueindustry based on information reported in 2017 of $55.6 billion, which represented 6.3% of total U.S. transportation revenue.Transport Topics. The LTL industry is highly competitive on the basis of service and price and has consolidated significantly since the industry was deregulated in 1980. Based on 2017 revenue as reported in Transport Topics, theThe largest 105 and 2510 LTL motor carriers accounted for approximately 55%58% and 67%83%, respectively, of the totaldomestic LTL market.market in 2020. We believe consolidation in our industry will continue due to increased customer demand for transportation providers offeringthat can offer both regional and national and regional LTLservice as well as other complementary value-added services.

Competition

The transportation and logistics industry is intensely competitive and highly fragmented. We compete with regional, inter-regional and national LTL carriers and, to a lesser extent, with truckload carriers, small package carriers, airfreight carriers and railroads. We also compete with, and provide transportation services to, third-party logistics providers that determine both the mode of transportation and the carrier. Some of our competitors may have a broader global network and a wider range of services than we do. Competition in our industry is based primarily on service, price, available capacity and business relationships. We believe we are able to gain market share by expanding our capacity in the United States and providing high-quality service at a fair price.

Throughout our organization, we continuously seek to improve customer service by, among other things, maximizing on-time performance and minimizing cargo claims. We believe our transit times are generally faster and more reliable than those of our principal national competitors, in part because of our more efficient service center network, use of team drivers and proprietary technology. In addition, we provide greater geographic coverage than most of our regional competitors. Our diversified mix and scope of regional, inter-regional and national LTL service, combined with our value-added service offerings, enables us to provide our customers with a single source to meet their shipping and logistics needs. We believe the combination of these factors provides us with a distinct advantage over most of our competitors.

We utilize flexible scheduling and train our employees to perform multiple tasks, which we believe allows us to achieve greater productivity and higher levels of customer service than our competitors. We believe our focus on employee communication, continued education, development and motivation strengthens the relationships and trust among our employees.

Service Center Operations

At December 31, 2018,2021, we operated 235251 service center locations, of which we owned 203227 and leased 32. Our network includes ten major breakbulk facilities located in Rialto, California; Atlanta, Georgia; Columbus, Ohio; Indianapolis, Indiana; Greensboro, North Carolina; Harrisburg, Pennsylvania; Memphis and Morristown, Tennessee; Dallas, Texas; and Salt Lake City, Utah, while using various other service centers for additional limited breakbulk activity in order to serve our next-day markets. Our service centers are strategically located throughout the country so that we can provide the highest quality service and minimize freight rehandling costs.

24. Our service centers are responsible for the pickup and delivery of freight within their local service area. Each night, our service centers load outbound freight for transport to our other service centers for delivery. All inbound freight received by the service center in the evening or during the night is generally scheduled for local delivery the next business day, unless a customer requests a different delivery schedule. Our management reviews the productivity and service performance of each service center on a daily basis to ensure quality service and efficient operations. Our network includes major breakbulk facilities, as well as various other service centers that are used for additional limited breakbulk activity in order to serve our next-day markets. Our service centers are strategically located throughout the country so that we can provide the highest quality service and minimize freight rehandling costs.

Although we have established primary responsibility for customer service at the local service center level, our customers may access information and initiate transactions through our centralized customer service department located at our corporate office or through other electronic gateways. Our systems allow us to offer our customers access to information such as freight tracking, shipping documents, rate quotes, rate databases and account activity. These centralized systems and our customer service department provide our customers with a single point of contact to access information across all areas of our operations and for each of our service offerings.

Linehaul Transportation

Linehaul dispatchers control the movement of freight between service centers through integrated freight movement systems. We also utilize load-planning software to optimize efficiencies in our linehaul operations. Our management team monitors freight movements, transit times, load factors and many other productivity measurements to help ensure that we maintain our high levels of service and efficiency.

We utilize scheduled routes and additional linehaul dispatches as necessary to meet our published transit times. In addition, we gain efficiency through the use of twin 28-foot trailers in our linehaul operations. The use of twin 28-foot trailers permits us to transport freight directly from its point of origin to destination with minimal unloading and reloading, which also reduces our exposure

to potential cargo loss and damage expenses. We utilize long-combination vehicles, such as triple 28-foot trailers and combinations of 48-foot and 28-foot trailers, in states where permitted. Twin trailers and long-combination vehicles permit more freight to be transported behind a tractor than could otherwise be transported by one trailer.

Tractors, Trailers and Maintenance

At December 31, 2018,2021, we owned 9,25410,403 tractors. We generally use new tractors in linehaul operations for approximately three to five years and then transfer those tractors to P&D operations for the remainder of their useful lives. In many of our service centers, tractors perform P&D functions during the day and linehaul functions at night to maximize tractor utilization.

The table below reflects, as of December 31, 2018,2021, the average age of our tractors and trailers:

We develop certain specifications for tractors and trailers and then negotiate the production and purchase of this equipment with several manufacturers. These purchases are planned well in advance of anticipated delivery dates in order to accommodate manufacturers’ production schedules. We generally believe there is sufficient capacity among suppliers to help ensure an uninterrupted supply of equipment to support our operations. Supply chain challenges have impacted our equipment manufacturers during 2021 and may continue to impact them during 2022. We will continue to use older equipment that would have otherwise been replaced based on our normal equipment cycle to help ensure that we have adequate capacity to support anticipated growth. We will also continue to utilize purchased transportation, as needed, in order to support the capacity of our workforce and equipment needs.

The table below sets forth our capital expenditures for tractors and trailers for the years ended December 31, 2018, 20172021 and 2016.2020. For more information concerning our capital expenditures, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” in this report.

At December 31, 2018,2021, we operated 3943 fleet maintenance centers at strategic service center locations throughout our network. These fleet maintenance centers are equipped to perform routine and preventive maintenance and repairs on our equipment.

We adhere to established maintenance policies and procedures to help ensure our fleet is properly maintained. Tractors are routed to appropriate maintenance facilities or authorized repair vendors at designated mileage intervals or every 90 days, whichever occurs first. Trailers are also scheduled for preventativepreventive maintenance every 90 days.

Customers

Revenue is generated primarily from customers throughout the United States and North America. In 2018,2021, our largest customer accounted for approximately 4.0%5.4% of our revenue and our largest 5, 10 and 20 customers accounted for 13.7%16.0%, 19.3%22.3% and 26.0%30.2% of our revenue, respectively. For each of our last threetwo fiscal years, more than 95% of our revenue was derived from services performed in the United States and less than 5% of our revenue was generated from services performed internationally. We believe the diversity of our customer base helps protect our business from adverse developments in a single geographic region and from the reduction or loss of business from a single customer.

We utilize an integrated freight-costing system to determine the price level at which a particular freight shipment of freight will be profitable. We can modify elements of this freight-costing model to simulate the actual conditions under which the freight will be moved. Many of our customers engage our services through the terms and provisions of our tariffs and through negotiated service contracts. We also compete for business by participating in bid solicitations. Customers generally solicit bids for relatively large numbers of shipments for a period of one to two years and typically choose to enter into contractual arrangements with a limited number of motor carriers based upon price and service.

Seasonality

Our tonnage levels and revenue mix are subject to seasonal trends common in our industry, although other factors, such as macroeconomic changes, could cause variation in these trends. Our revenue and operating margins in the first and fourth quarters are typically lower than those during the second and third quarters due to reduced shipments during the winter months. months; however, the effects of the COVID-19 pandemic on the domestic economy impacted our normal seasonal trends during 2020 and may continue to impact our seasonal trends in future periods. Harsh winter weather, or natural disasters, such as hurricanes, tornadoes, floods fires and other stormsnatural disasters can also adversely impact our performance by reducing demand and increasing operating expenses. We believe seasonal trends will continue to impact our business.

Technology

Our technology is critical to the success and delivery of the premium service provided by our operations. We continually seek to upgrade and enhance our technological capabilities. We also provide access to our systems through multiple secure gateways that offer our customers and employees maximum flexibility and access to information. We employ vehicle safety systems, forward-facing cameras, on-board and hand-held computer systems, smart phones, freight handling systems and logistics technology to reduce costs and transit times, as well as to meet regulatory requirements. Our data systems are integrated at every level within our organization, which we believe is critical to our success. Our systems are protected through physical and software safeguards, as well as redundant systems, network security measures and backup systems. We continue to focus on the development and enhancement of the technology used in our operations in order to improve the efficiency and effectiveness of our services.

Insurance

We carry a significant amount of insurance with third-party insurance carriers but we are exposed tothat provides various levels of protection for our risk exposure, including protection in the riskareas of loss on claims up to the limit for which we hold either a self-insured retention (“SIR”) or deductible. At December 31, 2018, we maintained a SIR or deductible of $1.0 million or more with respect to the belowproperty, casualty, cyber, management, and group health, coverages:

severity. We believe that our policy of maintaining a SIRself-insured retentions or deductibledeductibles under these various insurance programs for a portion of our risks, supported by our safety, claims management and loss prevention programs, is an effective means of managing insurance costs. We periodically review our risk exposure and insurance coverage applicable to those risks and we believe that we maintain sufficient insurance coverage.

Diesel Fuel Availability and Cost

We depend heavily upon the availability and quality of diesel fuel, including alternative fuel types, to provide our transportation services. We maintain fuel storage and pumping facilities at certain service center locations as the primary source for fueling our fleet, and we utilize over-the-road fueling options at retail locations as necessary. We could be susceptible to regional and/or national fuel shortages, which could cause us to incur additional expense in order to obtain an adequate supply within our own fueling network or cause us to rely more heavily on higher-priced retail fuel.

We believe our operations and financial condition are susceptible to the same diesel fuel price increases or shortages as those of our competitors. We implemented aOur fuel surcharge program in August 1999, which has remained in effect since that time and isprograms are one of many components that we use to determine the overall price for our transportation services. Our fuel surcharges are generally indexed to fuel prices published by the U.S. Department of Energy (the “DOE”) that reset each week.

EmployeesHuman Capital

Employee Profile

As of December 31, 2018,2021, we employed 21,279 individuals on a23,663 active full-time basis,employees, none of which were represented under a collective bargaining agreement. Our full-time employees work in the following roles:

Employee Engagement and Benefits

Our Old Dominion Family of employees are a key factor in the success of our business. The unique OD Family culture encourages development and employee engagement, and motivates our employees to provide the superior customer service for which we are known. We believe this culture is part of what attracts employees and helps keep our turnover rates low. We also provide our employees with a comprehensive benefits package, including a plan that covers our eligible employees’ premium for health insurance, voluntary disability and life insurance coverages, a flexible paid time off policy, a 401(k) plan with a guaranteed employer match as well as a discretionary employer match opportunity, and various wellness programs designed to assist employees with establishing and living a healthy and balanced lifestyle.

Employee Development and Safety

As of December 31, 2018,2021, we employed 5,7436,158 linehaul drivers and 5,4645,644 P&D drivers on a full-time basis. We select our drivers primarily based upon safemany factors, including driving records and experience. Among other requirements, our drivers must pass a drug test, have a current U.S. Department of Transportation (“DOT”) physical and have a valid commercial driver’s license prior to employment. Once employed, drivers are required to obtain and maintain hazardous materials endorsements to their commercial driver’s licenses. Drivers, like all of our employees, are required to take pre-employment drug and alcohol tests and are randomly selected for periodic additional testing.

Since 1988, we have provided thea no-cost opportunity for qualified employees to become drivers through the “Old Dominion Driver Training Program.” There are currently 3,2733,389 active drivers who have successfully completed this training, which was approximately 29.2%28.7% of our driver workforce as of December 31, 2018.2021. We believe our driver training and qualification programs have been important factors in improving our safety record and retaining qualified drivers. In fact, over 18% of our drivers have achieved one million safe driving miles or more. In addition, we have experienced an annual turnover rate for our driver graduates of approximately 5.7%6.4%, which is below our Company-wide turnover rate for all drivers of approximately 8.0%9.0%.

We rewardalso maintain a “Management Trainee Program” and a “Supervisor Development Program” that offers opportunities for our employees to be considered and prepared for sales and management opportunities. These programs support our philosophy of promoting from within our high-quality workforce.

Based on driving records, our drivers who maintain safe driving recordsare eligible to be rewarded with annual safety bonuses of up to $3,000 per driver. Our safety bonuses paid to drivers totaled $4.1$4.9 million, $3.9$4.7 million and $3.7$4.6 million in 2018, 20172021, 2020 and 2016,2019, respectively.

Throughout the COVID-19 pandemic, we have remained focused on protecting the health and safety of our employees while meeting the needs of our customers. We implemented various measures to help ensure the safety and well-being of our OD Family of employees, following guidelines issued by the U.S. Centers for Disease Control and Prevention and the World Health Organization. Across our businesses, we continue to take measures to prevent workplace hazards, encourage safe behaviors and promote a culture of continuous improvement to ensure our processes help reduce incidents and illnesses and comply with governing health and safety laws.

Governmental Regulation

We are regulated by the DOT and by various state and federal agencies. These regulatory authorities have broad powers over matters relating to authorized motor carrier operations, as well as motor carrier registration, driver hours of service, safety and fitness of transportation equipment and drivers, transportation of hazardous materials, certain mergers and acquisitions and periodic financial reporting. The trucking industry is also subject to regulatory and legislative changes from a variety of other governmental authorities, which address matters such as increasingly stringent environmental regulations, occupational safety and health regulations, limits on vehicle weight and size, ergonomics, port security, and driver hours of service.

In addition, we are subject to compliance with cargo-security and transportation regulations issued by the Transportation Security Administration (“TSA”) and Customs and Border Protection (“CBP”) within the U.S. Department of Homeland Security. Regulatory requirements, and changes in regulatory requirements or guidance, may affect our business or the economics of the industry by requiring changes in operating practices that could influence the demand for and increase the costs of providing transportation services.

Driver Hours of Service

The Federal Motor Carrier Safety Administration (the “FMCSA”) rules provide that a truck driver may work no more than a maximum number of 60 hours within seven consecutive days and 70 hours within eight consecutive days. FMCSA rules further impose a maximum work period of 14 hours (no more than 11 hours of which may be driving time) after first coming on-duty

following 10 consecutive hours of off-duty time. FMCSA rules also require that drivers take a 30-minute break prior to workingdriving beyond eight hours.

Electronic Logging Devices

In December 2015, the FMCSA issued a final rule mandating the use of Our drivers utilize electronic logging devices (“ELDs”) to automatically record drivers’ time for the purpose of recording their hours of service reporting. Generally, carriers were required to comply with these new requirements by December 18, 2017. We currently utilize ELD rule-compliant automatic on-board recording devices (“AOBRDs”) in all of our Company-owned vehicles, and the AOBRD data is integrated with our existing comprehensive fleet management and safety systems. In order to maximize our ability to integrate AOBRD data from vehicles purchased after December 18, 2017 with these fleet management and safety systems, we applied for a waiver from certain aspects of the ELD rule by the FMCSA in January 2018. This waiver proved unnecessary and was withdrawn as the FMCSA was made aware of multiple motor carriers facing the same issues from technology providers when changing from an AOBRD to an ELD operating system. The FMCSA issued responsive guidance that allowed AOBRD operating systems to be installed and utilized on ELD compliant hardware until December 16, 2019. We are working with service providers to transition our fleet from our current AOBRD operating system to a new ELD hardware and software platform. We expect the transition to be completed prior to December 2019.service. 

Commercial Driver’s License Drug and Alcohol Clearinghouse

In December 2016, the FMCSA releasedWe are registered as a final rule establishingmotor carrier with the Commercial Driver’s License Drug and Alcohol Clearinghouse, (“DAC”). The DAC is a database that will maintain records ofwhich requires us to check for drug and alcohol violations of commercial motor vehicle drivers. The DAC will require us to checkcurrent drivers at least annually and prospective employees for drugprior to hiring. We have completed our annual limited query and alcohol violations, and all currentpre-hire driver employees must be checked at least annually. The intent of the clearinghouse is to ensure that drivers cannot conceal drug and alcohol violations

by changing jobs or locations. Compliance with this rule, which provides for a three-year implementation period, is required by January 6, 2020.

We are subject to future rulemaking by the FMCSA and other regulatory agencies, which could be more stringent, require additional changes to our operations, increase our operating costs or otherwise adversely impact our results of operations.authorization queries.

Environmental Regulation

We are subject to various federal, state and local environmental laws and regulations that focus on, among other things: the disposal, emission and discharge of hazardous waste, hazardous materials, or other materials into the environment or their presence at our properties or in our vehicles; fuel storage tanks; transportation of certain materials; and the discharge or retention of storm water. Under specific environmental laws, we could also be held responsible for any costs relating to contamination at our past or present facilities and at third-party waste disposal sites, as well as costs associated with clean-up of accidents involving our vehicles. We do not believe that the cost of future compliance with current environmental laws or regulations will have a material adverse effect on our operations, financial condition, competitive position or capital expenditures for the remainder of 20192022 or fiscal year 2020.2023. However, future changes to laws or regulations may adversely affect our operations and could result in unforeseen costs to our business.

ITEM 1A. RISK FACTORS

Various factors exist that could causeAn investment in our actual results to differ materially from those projected in any forward-looking statement. In addition to the factors discussed elsewhere in this report, we believe thecommon stock involves a variety of risks and uncertainties. The following aredescribes some of the importantmaterial risks and uncertainties that could materiallyadversely affect our business, financial condition, operating results or results of operations:

We operate in a highly competitive industry, and our business will suffer if we are unable to adequately address potential downward pricing pressures and other factors that may adversely affect our operations and profitability.

Numerous competitive factors could impair our ability to maintain our current profitability. These factors include, but are not limited to, the following:

If we are unable to effectively compete with other LTL carriers, whether on the basis of price, service or otherwise, we may be unable to retain existing customers or attract new customers, either of which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, continued merger and acquisition activity in transportation and logistics could result in stronger or new competitors, which could have a material adverse effect on our business, financial condition and results of operations.cash flows. We may also be adversely impacted by other risks not be ablepresently known to compete successfully in an increasingly consolidated LTL industry and cannot predict with certainty how industry consolidation will affect our competitors or us.

If our employees were to unionize, our operating costs would increase and our ability to compete would be impaired.

None of our employees are currently represented under a collective bargaining agreement. However, from time to time there have been efforts to organize our employees at various service centers. Further, Congress or one or more states could approve legislation and/or the National Labor Relations Board could render decisions or implement rule changes that could significantly affect our business and our relationship with our employees, including actions that could substantially liberalize the procedures for union organization. In addition, we can offer no assurance that the Department of Labor will not adopt new regulations or interpret existing regulations in a manner that would favor the agenda of unions,us or that we currently consider immaterial.

Risks Related to our employees will not unionize in the future, particularly if regulatory changes occur that facilitate unionization.

The unionization of our employees could have a material adverse effect on our business, financial conditionBusiness and results of operations because:Operations

If we are unable to successfully execute our growth strategy, and develop, market and consistently deliver high-quality services that meet customer expectations, our business and future results of operations may suffer.

Our growth strategy includes increasing the volume of freight moving through our existing service center network and selectively expanding our capacity and broadeningin the scope of our service offerings.United States through market share gains. In connection with our growth strategy, at various times, we have consistently expanded and upgraded service centers, purchased additional equipment and increased our sales and marketing efforts, and we expect to continue to do so. Our growth strategy exposes us to a number of risks, including the following:

We cannot ensure that we will overcome the risks associated with our growth strategy. If we fail to overcome those risks, we may not realize additionalprojected growth and related revenue or profits from our efforts, we may incur additional expenses and, as a result, our financial position and results of operations could be materially and adversely affected.

We face various risks related to health epidemics, pandemics and similar outbreaks that have had, and may continue to have, adverse effects on our business, results of operations and financial condition.

The novel coronavirus (COVID-19) pandemic, the governmental/social responses thereto and the related changes in the economic and political conditions in markets in which we operate have had adverse impacts on our business, results of operations and financial condition, and on those of our customers and suppliers, and these adverse impacts may continue. These impacts and potential impacts include, among other things, significant reductions or volatility in demand for our services, inability of our customers to timely pay for our services, and failure of our suppliers or third-party service providers to meet their obligations to us. We may also experience capacity constraints in one or more geographic areas if a significant number of our employees in any such region are affected by COVID-19. Furthermore, COVID-19 has impacted and may further impact the global economy, including negatively impacting the proper functioning of financial and capital markets and interest rates, which at times has impacted the cost of capital and limited access to capital. As the COVID-19 pandemic continues to adversely affect our business, results of operations and financial condition, it has heightened, and will likely continue to heighten, other risks to which we are subject, including those related to economic downturns, customer/supplier/vendor operations, labor issues, inflationary pressures, supply chain disruptions, changes in political and regulatory conditions, liquidity, and industry pricing environment stability, as described in further detail in other risk factors. Despite our efforts to manage our exposure to these risks, the ultimate impact of COVID-19 and similar outbreaks depends on factors beyond our knowledge or control, including the duration and severity of any outbreak and governmental/social actions taken to contain its spread and mitigate its public health impact.

Changes in our relationships with significant customers, including the loss or reduction in business from one or more of them, could have an adverse impact on our business.

We do not believe the loss of any one customer would materially impact our business and revenue growth due to the diversity of our customer base. We do, however, have a number of customers whose demand for our services is tied to U.S. industrial production, or the broader domestic economy, that could, collectively, drive business and revenue growth. These customers could experience a decrease in production due to a decrease in the demand for their products, as a result of a decline in the U.S economy or other global economic factors, such as the slowdown in the domestic economy associated with the COVID-19 pandemic. They could also use other LTL providers and other modes of transportation, such as truckload and intermodal, in response to capacity, service and pricing issues. Finally, unfavorable publicity about us or our employees, particularly given the current environment of instantaneous communication and social media outlets, could damage our reputation and result in these customers reducing their demand for our services. If these factors resulted in a reduction or loss of business from these customers, there could be a material impact on our business and revenue growth.

Insurance and claims expenses could significantly reduce our profitability.

We are exposed to a variety of claims, including but not limited to those related to cargo loss and damage, property damage, personal injury, workers’ compensation and healthcare. We have insurance coverage with third-party insurance carriers, but we assume a significant portion of the risk associated with these claims due to our self-insured retentions and deductibles. Our operating results could be adversely affected if any of the following were to occur: (i) the number or the severity of claims increases; (ii) we are required to accrue or pay additional amounts because claims prove to be more severe than our original assessment; or (iii) claims exceed our coverage amounts. If claims exceed our self-insured retention or deductible levels, insurance companies exit the transportation insurance marketplace, or insurance market conditions change, insurers could raise premiums for excess coverage to cover their expenses and anticipated future losses. Coverage also may not be procured or be unavailable for certain claims. In addition, insurance companies generally require us to collateralize our self-insured retention or deductible levels. If these collateralization requirements increase, our borrowing capacity could be adversely affected.

Reductions in the available supply or increases in the cost of new equipment may adversely impact our profitability and cash flows.

We may face difficulty in purchasing new equipment due to decreased supply or increased costs. Investment in new equipment is a significant part of our annual capital expenditures and we require an available supply of tractors, trailers, and other freight handling equipment from manufacturers to operate and grow our business. We may also be subject to shortages in raw materials that

are required for the production of critical operating equipment and supplies, such as shortages in rubber or steel. Currently, tractor and trailer manufacturers are experiencing significant shortages of various component parts and supplies, forcing many manufacturers to reduce or suspend their production, which has led to a lower supply of tractors, trailers, and other equipment, higher prices, and lengthened trade cycles.

In addition, the availability and price of our equipment may also be adversely affected in the future by regulations on newly manufactured equipment and engines. We are subject to regulations issued by the U.S. Environmental Protection Agency (the “EPA”) and various state agencies, particularly the California Air Resources Board (“CARB”), that have required progressive reductions in exhaust emissions. We may become subject to new or more restrictive regulations, or differing interpretations of existing regulations, which may increase the cost of providing transportation services or adversely affect our results of operations. We are also unable to predict how any future changes in U.S. government policy will affect EPA and CARB regulation and enforcement.

These regulations, the limited equipment availability, and other supply chain factors have resulted and could continue to result in higher prices for new equipment, which could have a material adverse effect on our business, financial condition, and results of operations, particularly our maintenance expense, mileage productivity, and driver retention.

Our growth may be limited by the availability and cost of third-party transportation used to supplement our workforce and equipment needs.

Our growth strategy depends upon our ability to maintain adequate capacity throughout our service center network to support the transportation service needs of our customers. In order to maintain adequate capacity to support our customers’ demand for our services we may, from time to time, utilize third-party transportation services to supplement our workforce and equipment needs. If we are unable to find suitable third-party transportation service providers that meet our high service-delivery standards at a reasonable cost, when needed, our revenue growth and financial results may be adversely impacted.

We may be adversely impacted by fluctuations in the availability and price of diesel fuel.

Diesel fuel is a critical component of our operations and a significant operating expense for our business. Future fluctuations in prices and diesel fuel availability could have a material adverse effect on our operating results. Diesel fuel prices and fuel availability can be impacted by factors beyond our control, such as natural or man-made disasters, adverse weather conditions, political events, disruption or failure of technology or information systems, price and supply decisions by oil producing countries and cartels, terrorist activities, armed conflict, world supply and demand imbalances, tariffs, sanctions, and quotas or other changes to trade agreements. We maintain fuel storage and pumping facilities at many of our service center locations; however, we may be susceptible to fuel shortages at certain locations that could cause us to incur additional expense to ensure adequate supply on a timely basis and to prevent a disruption to our service schedules. An interruption in the supply of diesel fuel could have a material adverse effect on our operating results.

We do not hedge against the risk of diesel fuel price increases. An increase in diesel fuel prices or diesel fuel taxes, or any change in federal or state regulations that results in such an increase, could have a material adverse effect on our operating results. We have fuel surcharge programs in place with a majority of our customers, which help offset the negative impact of the increased cost of diesel fuel and other petroleum-based products. However, we also incur fuel costs that cannot be recovered even with respect to customers with which we maintain fuel surcharge programs, such as those costs associated with empty miles. Because our fuel surcharge recovery lags behind changes in fuel prices, our fuel surcharge recovery may not capture the increased costs we pay for fuel, especially when prices are rising, leading to fluctuations in our levels of reimbursement. We regularly monitor the components of our pricing, including fuel surcharges, and address individual account profitability issues with our customers when necessary; however, there can be no assurance that fuel surcharges can be maintained indefinitely or will be sufficiently effective in offsetting increases in diesel fuel prices.

Our results of operations may be affected by seasonal factors, harsh weather conditions and disasters.

Our operations are subject to seasonal trends common in our industry. Our revenue and operating margins in the first and fourth quarters are typically lower than those during the second and third quarters due to reduced shipments, decreased fuel efficiency, increased cold-weather related maintenance costs of revenue equipment, and increased insurance and claims costs during the winter months; however, the effects of the COVID-19 pandemic on the domestic economy has impacted, and may continue to impact, our normal seasonal trends. Harsh winter weather or natural disasters, including but not limited to hurricanes, tornadoes, floods, fires, earthquakes and storms can also adversely impact our performance by disrupting freight shipments or routes, destroying our assets, disrupting fuel supplies, increasing fuel costs, increasing maintenance costs, reducing demand and negatively impacting the business or financial condition of our customers, any of which could harm our results of operations or make our results of operations more volatile.

We have significant ongoing cash requirements that could limit our growth and affect our profitability if we are unable to obtain sufficient capital.

Our business is highly capital intensive. As further described in Part II, Item 7 of this Annual Report on Form 10-K, we generally finance our capital expenditures and planned growth with existing cash, cash flows from operations, issuance of debt (including pursuant to our note purchase and private shelf agreement) and through available borrowings under our existing senior unsecured credit agreement. We may require additional capital to finance long-term real estate purchase opportunities and acquisitions, which we may fund through additional debt or through equity offerings. If we are unable to generate sufficient cash from our operations or raise capital by accessing the debt and equity markets, we may be forced to limit our growth and operate our equipment for longer periods of time, which could have a material adverse effect on our operating results.

Our business also has significant ongoing operating cash requirements. If our cash requirements are high or our cash flows from operations is low during particular periods, we may need to seek additional financing, which could be costly or difficult to obtain.

A decrease in the demand and value of used equipment may impact our results of operations.

As we purchase new tractors and trailers as part of our normal replacement cycle each year, we rely on the used equipment market to dispose of our older equipment. Oversupply in the transportation industry as well as adverse domestic and foreign economic conditions can negatively impact the demand for used equipment and, therefore, reduce the value we can obtain on our used equipment. If we are unable to sell our older equipment at or above our salvage value, the resulting losses could have a significant impact on our results of operations.

We may be unable to successfully consummate and integrate acquisitions as part of our growth strategy.acquisitions.

Growth through acquisitions historically has been a key component of our LTL growth strategy. In the future, we may seek to acquire other LTL carriers as well as other complementary businesses. Exploration of potential acquisitions requires significant attention from our management team. In addition, we expect to compete for acquisition opportunities with other companies, some of which may have greater financial and other resources than we do. We cannot ensure that we will have sufficient cash to consummate an acquisition or otherwise be able to obtain financing for an acquisition. If we are unable to access sufficient funding for potential acquisitions, we may not be able to complete transactions that we otherwise find advantageous.

Any subsequent acquisition will entail numerous risks, including:

In addition, we may have difficulty integrating any acquired business and its operations, services and personnel into our existing operations, and such integration may require a significant amount of time and effort by our management team. To the extent we do not successfully avoid or overcome the risks or problems resulting from any acquisitions we undertake, there could be a material adverse effect on our business, financial condition and results of operations.

We are subject to various risks arising from our international business operations and relationships, which could adversely affect our business.

We arrange for transportation and logistics services to and from various international locations and are subject to both the risks of conducting international business and the requirements of the Foreign Corrupt Practices Act of 1977 (the “FCPA”). Failure to comply with the FCPA may result in legal claims against us. In addition, we face other risks associated with international operations and relationships, which may include restrictive trade policies, the renegotiation of international trade agreements, imposition of duties, taxes or government royalties imposed by foreign governments, which could adversely affect our business.

Anti-terrorism measures and terrorist events may disrupt our business.

Federal, state and municipal authorities have implemented and are continuing to implement various anti-terrorism measures, including checkpoints and travel restrictions on large trucks. If additional security measures disrupt or impede the timing of our deliveries, we may fail to meet the requirements of our customers or incur increased expenses to do so. There can be no assurance that new anti-terrorism measures will not be implemented and that such measures will not have a material adverse effect on our operations.

Risks Related to our Industry

We operate in a rapidly evolving and highly competitive industry, and our business will suffer if we are unable to adequately address potential downward pricing pressures and other factors that may adversely affect our operations and profitability.

Our industry, faced with requirements for faster deliveries and increased visibility into shipments, is rapidly evolving and increasingly competitive. Numerous competitive factors could impair our ability to maintain our current profitability. These factors include, but are not limited to, the following:

If we are unable to effectively compete with other LTL carriers, whether on the basis of price, service, brand recognition or otherwise, we may be unable to retain existing customers or attract new customers, either of which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, continued merger and acquisition activity in transportation and logistics could result in stronger or new competitors, which could have a material adverse effect on our business, financial condition and results of operations. We may not be able to compete successfully in an increasingly consolidated LTL industry and cannot predict with certainty how industry consolidation will affect our competitors or us.

Our customers’ and suppliers’ businesses may be impacted by various economic factors such as recessions, downturns in the economy, global uncertainty and instability, changes in U.S. social, political, and regulatory conditions and/or a disruption of financial markets, which may decrease demand for our services or increase our costs.

Adverse economic conditions, both in the U.S. and internationally, can negatively affect our customers’ business levels, the amount of transportation services they need, their ability to pay for our services and overall freight levels, any of which might impair our asset utilization. Additionally, uncertainty and instability in the global economy and any other action that the U.S. government may take to withdraw from or materially modify international trade arrangements, including related to the United States-Mexico-Canada Agreement, which was agreed upon on September 30, 2018 and is designed to replace the North American Free Trade Agreement, may lead to fewer goods being transported and could have a material adverse effect on our business, financial conditions and results of operations. The U.S. government has made significant changes in U.S. trade policy and has taken certain other actions that may impact U.S. trade, including imposing tariffs on certain goods imported into the United States. To date, several governments, including the European Union, China, and India, have imposed tariffs on certain goods imported from the United States. Any further changes in U.S. or international trade policy could trigger additional retaliatory actions by affected countries, resulting in “trade wars” and increased costs for goods transported globally, which may reduce customer demand for these products if the parties having to pay those tariffs increase their prices, or in trading partners limiting their trade with countries that impose anti-trade measures. If these consequences are realized, the volume of global economic activity may be significantly reduced. Such a reduction could have a material adverse effect on our business, results of operations and financial condition.

Customers adversely impacted by changes in U.S. trade policies or otherwise encountering adverse economic conditions, including as a result of the COVID-19 pandemic, may be unable to obtain additional financing or financing under acceptable terms. These customers represent a greater potential for bad debt losses, which may require us to increase our reserve for bad debt. Economic conditions resulting in bankruptcies of one or morea concentration of our large customers could have a significant impact on our financial position, results of operations or liquidity in a particular year or

quarter. Further, when adverse economic times arise, customers may select competitors that offer lower rates in an attempt to lower their costs, and we might be forced to lower our rates or lose freight volumes.

Our suppliers’ business levels also may be negatively affected by adverse economic conditions and changes in the political and regulatory environment, both in the U.S. and internationally, or financial constraints, including as a result of the COVID-19 pandemic, which could lead to disruptions in the supply and availability of equipment, parts and services critical to our operations. A significant interruption in our normal supply chain could disrupt our operations, increase our costs and negatively impact our ability to serve our customers.

We are also subject to cost increases outside of our control that could materially reduce our profitability if we are unable to increase our rates sufficiently. Such cost increases include, but are not limited to, increases in wage rates, fuel prices, interest rates, taxes, tolls, license and registration fees, insurance, revenue equipment and healthcare for our employees.

Difficulties attractingRisks Related to Labor Matters

If our employees were to unionize, our operating costs would increase and retainingour ability to compete would be impaired.

None of our employees are currently represented under a collective bargaining agreement. However, from time to time there have been efforts to organize our employees at various service centers. Further, Congress or one or more states could approve legislation and/or the National Labor Relations Board could render decisions or implement rule changes that could significantly affect our business and our relationship with our employees, including actions that could substantially liberalize the procedures for union organization. In addition, we can offer no assurance that the Department of Labor will not adopt new regulations or interpret existing regulations in a manner that would favor the agenda of unions, or that our employees will not unionize in the future, particularly if regulatory changes occur that facilitate unionization.

The unionization of our employees could have a material adverse effect on our business, financial condition and results of operations because:

Increases in employee compensation and benefit packages used to attract and retain qualified employees, including drivers and maintenance technicians, could result in increases in driver and technician compensation andaddressing general labor market challenges could adversely affect our profitability, our ability to maintain or grow our fleet and our ability to maintain our customer relationships.

From time to time we have experienced difficultyRecently, there has been intense competition for qualified employees, specifically drivers, in attracting and retaining sufficient numbersthe transportation industry resulting from a shortage of qualified drivers and such shortages may recur ingeneral labor market challenges. The extent and duration of the future. Due in partimpact of these challenges are subject to numerous factors, including the time commitment, physical requirements,continuing impact of the COVID-19 pandemic, our stringent hiring standards, behavioral changes, prevailing wage rates and current industry conditions,other benefits, health and other insurance costs, inflation, adoption of new or revised employment and labor laws and regulations or government programs, and changing workforce demographics. As the available pool of qualified employee drivers has been declining. Because of the intense competition for drivers,declining, we have faced, and may continue to face, difficulty maintaining or increasing our number of drivers. Similarly, in recent years, there has been a decrease in the overall supply of skilled maintenance technicians, particularly new technicians with qualifications from technical programs and schools, which couldhas made it more difficult, and may continue to make it more difficult, to attract and retain skilled technicians. The compensation and benefit packages we offer our drivers, technicians and techniciansother specialized employees is subject to market conditions that have required and may in the future require further increases in driver or technician compensation.wages and benefits. If we are unable to attract and retain a sufficient number of qualified drivers and technicians, or address general labor market challenges, we could be required to adjust our compensation and benefits packages, amend our hiring standards, or operate with fewer trucks and face difficulty meeting customer demands, any of which could adversely affect our growth and profitability.

The FMCSA’s CSA initiative could adversely impact our ability to hire qualified drivers, meet our growth projections and maintain our customer relationships, each of which could adversely impact our results of operations.

The FMCSA’s Compliance, Safety, Accountability initiative (“CSA”) is an enforcement and compliance program designed to monitor and improve commercial motor vehicle safety by measuring the safety record of both the motor carrier and the driver. These measurements are scored and used by the FMCSA to identify potential safety risks and to direct enforcement action.

Our CSA scores are dependent upon our safety and compliance experience, which could change at any time. In addition, the safety standards prescribed in CSA could change and our ability to maintain an acceptable score could be adversely impacted. Public disclosure of certain CSA scores was restricted through the enactment of the Fixing America’s Surface Transportation Act of 2015 (the “FAST Act”) on December 4, 2015; however, the FAST Act does not restrict public disclosure of all data collected by the FMCSA. If we receive unacceptable CSA scores, and this data is made available to the public, our relationships with our customers could be damaged, which could result in a loss of business.

The requirements of the CSA could also shrink the industry’s pool of drivers, as those with unfavorable scores could leave the industry. As a result, the costs to attract, train and retain qualified drivers could increase. In addition, a shortage of qualified drivers could increase driver turnover, decrease asset utilization, limit growth and adversely impact our results of operations.

We operate in a highly regulated industry, and increased costs of compliance with, or liability for violation of, existing or future regulations could have a material adverse effect on our business.

We are regulated by the DOT and by various state and federal agencies. These regulatory authorities have broad powers over matters relating to authorized motor carrier operations, as well as motor carrier registration, driver hours of service, safety and fitness of transportation equipment and drivers, transportation of hazardous materials, certain mergers and acquisitions and periodic financial reporting. The trucking industry is also subject to regulatory and legislative changes from a variety of other governmental authorities, which address matters such as increasingly stringent environmental regulations, occupational safety and health regulations, limits on vehicle weight and size, ergonomics, port security, and driver hours of service. We are also subject to the costs and potential adverse impact of compliance associated with FMCSA’s ELD regulations and guidance, including the transition of our fleet and safety management systems from our legacy electronic AOBRDs to a new ELD hardware and software platform. In addition, we are subject to compliance with cargo-security and transportation regulations issued by the TSA and CBP within the U.S. Department of Homeland Security. Regulatory requirements and changes in regulatory requirements or guidance, together with the growing compliance risks presented by increased differences between applicable federal and state regulations, may affect our business or the economics of the industry by requiring changes in operating practices that could influence the demand for and increase the costs of providing transportation services.

Insurance and claims expenses could significantly reduce our profitability.

We are exposed to claims related to cargo loss and damage, property damage, personal injury, workers’ compensation, group health and group dental. We have insurance coverage with third-party insurance carriers, but we assume a significant portion of the risk associated with these claims due to our SIRs and deductibles. Our operating results could be adversely affected if any of the following were to occur: (i) the number or the severity of claims increases; (ii) we are required to accrue or pay additional amounts because claims prove to be more severe than our original assessment; or (iii) claims exceed our coverage amounts. If claims exceed our SIR or deductible levels, insurance companies exit the transportation insurance marketplace, or insurance market conditions change, insurers could raise premiums for excess coverage to cover their expenses and anticipated future losses.  In addition, insurance companies generally require us to collateralize our SIR or deductible levels. If these collateralization requirements increase, our borrowing capacity could be adversely affected.

Healthcare legislation may increase our costs and reduce our future profitability.

To attract and retain employees, we maintain a competitive health insurance plan for our employees and their dependents. We cannot predict the impact that any state or federal healthcare legislation or regulation will have on our operations, but we expect costs associated with providing benefits under employee medical plans and healthcare-related costs associated with workers’ compensation to continue to increase. Rising healthcare costs in the U.S. could result in significant long-term costs to us, which could have a material adverse effect on our operating results. In addition, rising healthcare costs could force us to make further changes to our benefits program, which could negatively impact our ability to attract and retain employees.

We have significant ongoing cash requirements that could limit our growth and affect our profitability if we are unable to obtain sufficient capital.

Our business is highly capital intensive. We generally finance our capital expenditures and planned growth with existing cash, cash flow from operations, issuance of debt and through available borrowings under our existing senior unsecured credit agreement. We may require additional capital to finance long-term real estate purchase opportunities and acquisitions, which we may fund through additional debt or through equity offerings. If we are unable to generate sufficient cash from our operations or raise capital by accessing the debt and equity markets, we may be forced to limit our growth and operate our equipment for longer periods of time, which could have a material adverse effect on our operating results.

Our business also has significant ongoing operating cash requirements. If our cash requirements are high or our cash flow from operations is low during particular periods, we may need to seek additional financing, which could be costly or difficult to obtain.

Limited supply and increased costs of new equipment may adversely affect our earnings and cash flow.

We may face difficulty in purchasing new equipment due to decreased supply and increased costs. Investment in new equipment is a significant part of our annual capital expenditures and we require an available supply of tractors and trailers from equipment manufacturers to operate and grow our business. We may also be subject to shortages in raw materials that are required for the production of critical operating equipment and supplies, such as shortages in rubber or steel.

The price of our equipment may also be adversely affected in the future by regulations on newly manufactured tractors and diesel engines. We are subject to regulations issued by the U.S. Environmental Protection Agency (the “EPA”) and various state agencies, particularly the California Air Resources Board (“CARB”), that have required progressive reductions in exhaust emissions from diesel engines. We may become subject to new or more restrictive regulations, or differing interpretations of existing regulations, which may increase the cost of providing transportation services or adversely affect our results of operations. We are also unable to predict how any future changes in U.S. government policy will affect EPA and CARB regulation and enforcement. These regulations have resulted in higher prices for tractors and diesel engines and increased operating and maintenance costs, and there can be no assurance that continued increases in pricing or costs will not have an adverse effect on our business and results of operations.

We may be adversely impacted by fluctuations in the availability and price of diesel fuel.

Diesel fuel is a critical component of our operations and a significant operating expense for our business. Future fluctuations in prices and diesel fuel availability could have a material adverse effect on our operating results. Diesel fuel prices and fuel availability can be impacted by factors beyond our control, such as natural or man-made disasters, adverse weather conditions, political events, disruption or failure of technology or information systems, price and supply decisions by oil producing countries and cartels, terrorist activities, armed conflict, world supply and demand imbalances, tariffs, sanctions, and quotas or other changes to trade agreements. We maintain fuel storage and pumping facilities at many of our service center locations; however, we may be susceptible to fuel shortages at certain locations that could cause us to incur additional expense to ensure adequate supply on a timely basis and to prevent a disruption to our service schedules. An interruption in the supply of diesel fuel could have a material adverse effect on our operating results.

We do not hedge against the risk of diesel fuel price increases. An increase in diesel fuel prices or diesel fuel taxes, or any change in federal or state regulations that results in such an increase, could have a material adverse effect on our operating results. We have fuel surcharge programs in place with a majority of our customers, which help offset the negative impact of the increased cost of diesel fuel and other petroleum-based products. However, we also incur fuel costs that cannot be recovered even with respect to customers with which we maintain fuel surcharge programs, such as those costs associated with empty miles or the time during which our engines are idling. Because our fuel surcharge recovery lags behind changes in fuel prices, our fuel surcharge recovery may not capture the increased costs we pay for fuel, especially when prices are rising, leading to fluctuations in our levels of reimbursement. We regularly monitor the components of our pricing, including fuel surcharges, and address individual account profitability issues with our customers when necessary; however, there can be no assurance that fuel surcharges can be maintained indefinitely or will be sufficiently effective in offsetting increases in diesel fuel prices.

We are subject to various governmental laws and regulations, and costs of compliance with, liabilities under, or violations of, existing or future governmental laws or regulations could adversely affect our business.

We are subject to various federal, state and local governmental laws and regulations that govern, among other things, the emission and discharge of hazardous materials into the environment, the presence of hazardous materials at our properties or in our vehicles, fuel storage tanks, the transportation of certain materials and the discharge or retention of storm water. Under certain environmental laws, we could also be held responsible for any costs relating to contamination at our past or present facilities and at third-party waste disposal sites, as well as costs associated with the clean-up of accidents involving our vehicles. Environmental laws have become and may continue to be increasingly more stringent over time, and there can be no assurance that our costs of complying with current or future environmental laws or liabilities arising under such laws will not have a material adverse effect on our business, operations or financial condition.

In addition to EPA and state agency regulations on exhaust emissions with which we must comply, there is an increased legislative and regulatory focus on climate change, greenhouse gas emissions and the impact of global warming. State and local governments are increasingly considering greenhouse gas emissions regulation. This possibility of increased regulation of greenhouse gas emissions potentially exposes us to significant new taxes, fees and other costs. We are also subject to increasing sensitivity to sustainability issues. This increased focus on sustainability may result in new regulations and/or customer requirements that could adversely impact our business. Any future limitations on the emission of greenhouse gases, other environmental legislation or customer sustainability requirements could increase our future capital expenditures and have an adverse impact on our financial condition, results of operations and liquidity.

We are subject to the risks of litigation and governmental proceedings or inquiries, which could adversely affect our business.

The nature of our business exposes us to the potential for various claims and litigation related to labor and employment, personal injury, property damage, cargo claims, safety and contract compliance, environmental liability and other matters. Accordingly, we are, and in the future may be, subject to legal proceedings and claims that have arisen in the ordinary course of our business, and may include class-action allegations. We are also subject to potential governmental proceedings, inquiries, and claims. The parties in such actions may seek amounts from us that may not be covered in whole or in part by insurance.  Defending ourselves against such actions could result in significant costs and could require a substantial amount of time and effort by our management team. We cannot predict the outcome of litigation or governmental proceedings or inquiries to which we are a party or whether we will be subject to future legal actions. As a result, the potential costs associated with legal actions against us could adversely affect our business, financial condition or results of operations.

We are subject to various risks arising from our international business operations and relationships, which could adversely affect our business.

We arrange for transportation and logistics services to and from various international locations and are subject to both the risks of conducting international business and the requirements of the Foreign Corrupt Practices Act of 1977 (the “FCPA”). Failure to comply with the FCPA may result in legal claims against us. In addition, we face other risks associated with international operations and relationships, which may include restrictive trade policies, the renegotiation of international trade agreements, imposition of duties, taxes or government royalties imposed by foreign governments, which could adversely affect our business.

We are subject to legislative, regulatory, and legal developments involving taxes.

Taxes are a significant part of our expenses.  We are subject to U.S. federal and state income, payroll, property, sales and use, fuel, and other types of taxes. The Tax Cuts and Jobs Act (the “Tax Act”), which was enacted on December 22, 2017, includes a broad range of tax reform provisions affecting businesses, including lower corporate tax rates, changes in business deductions, and international tax provisions. Changes to tax laws and regulations or changes to the interpretation thereof (including regulations and interpretations pertaining to the Tax Act), the ambiguity of tax laws and regulations, the subjectivity of factual interpretations, higher

tax rates, claims, audits, investigations or legal proceedings involving taxing authorities, could have a material adverse effect on our results of operations, financial condition, and cash flows.

Our results of operations may be affected by seasonal factors, harsh weather conditions and disasters.

Our operations are subject to seasonal trends common in our industry. Our revenue and operating margins in the first and fourth quarters are typically lower than those during the second and third quarters due to reduced shipments during the winter months. Harsh winter weather or natural disasters, such as hurricanes, tornadoes, floods, fires and other storms can also adversely impact our performance by reducing demand and reducing our ability to transport freight, which could result in decreased revenue and increased operating expenses.

If we are unable to retain our key employees, or if we do not continue to effectively execute our succession plan, our financial condition, results of operations and liquidity could be adversely affected.

Our success will continue to depend upon the experience and leadership of our key employees and executive officers. In that regard, the loss of the services of any of our key personnel could have a material adverse effect on our financial condition, results of operations and liquidity if we are unable to secure replacement personnel who have sufficient experience in our industry and in the management of our business. If we are unable to continue to develop and retain a core group of management personnel and execute succession planning strategies, or we encounter any unforeseen difficulties associated with the transition of members of our management team, our business could be negatively impacted in the future.

Our principal shareholders control a large portion of our outstanding common stock.

Earl E. Congdon, David S. Congdon, John R. Congdon, Jr.Risks Related to Cybersecurity and their affiliate family members beneficially own an aggregate of approximately 19% of the outstanding shares of our common stock. As long as the Congdon family controls a large portion of our voting stock, they may be able to significantly influence the election of the entire Board of Directors and the outcome of all matters involving a shareholder vote. The Congdon family’s interests may differ from the interests of other shareholders and the status of their ownership could change at their discretion.

Our financial results may be adversely impacted by potential future changes in accounting practices.

Future changes in accounting standards or practices, and related legal and regulatory interpretations of those changes, may adversely impact public companies in general, the transportation industry or our operations specifically. New accounting standards or requirements could change the way we record revenues, expenses, assets and/or liabilities or could be costly to implement. These types of regulations could have a negative impact on our financial position, liquidity, results of operations and/or access to capital.Technology Matters

Our information technology systems are subject to cyber and other risks, some of which are beyond our control, which could have a material adverse effect on our business, results of operations and financial position.

We rely heavily on the proper functioning and availability of our information systems for our operations as well as for providing value-added services to our customers. Our information systems, including our accounting, communications and data processing systems, are integral to the efficient operation of our business. It is critical that the data processed by these systems remainremains confidential, as it often includes competitive customer information, confidential customer credit cardpayment and transaction data,information, employee records and key financial and operational results and statistics. The sophistication of efforts by hackers, foreign governments, cyber-terrorists, and cyber-criminals, acting individually or in coordinated groups, to launch distributed denial of service attacks or other coordinated attacks that may cause service outages, gain inappropriate or block legitimate access to systems or information, or result in other business interruptions has continued to increase in recent years. We utilize third-party service providers who have access to our systems and certain sensitive data, which exposes us to additional security risks, particularly given the complex and evolving laws and regulations regarding privacy and data protection. While we and our third-party service providers have experienced cyber-attacks and attempted breaches of our and their information technology systems and networks or similar events from time to time, no such incidents have been, individually or in the aggregate, material to us. Cyber incidents that impact the security, availability, reliability, speed, accuracy or other proper functioning of our systems, information and measures, including outages, computer viruses, break-ins and similar disruptions, could have a significant impact on our operations.

AlthoughWe have security processes, protocols and standards in place to protect our information systems, are protectedincluding through physical and software safeguards, as well as redundant systems, network security measures and backup systems,systems. Nevertheless, it is difficult to fully protect against the possibility of power loss, telecommunications failures, cyber attacks,cyber-attacks, and other cyber incidents in every potential circumstance that may arise. A significant cyber incident, including system failure, security breach, disruption by malware or ransomware, or other damage, could interrupt or delay our operations, damage our reputation and brand, cause a loss of customers, expose us to a risk of loss or litigation, result in regulatory scrutiny, investigations, actions, fines or penalties and/or cause us to incur significant time and expense to remedy such an event, any of which could have a material adverse impact on our results of operations and financial position. Furthermore, any failure to comply with data

privacy, security or other laws and regulations, such as the California Consumer Privacy Act and similar laws in the United States, at both the federal and state level, could result in claims, legal or regulatory proceedings, inquiries or investigations. As cyber threats are continually evolving, our controls and procedures may become inadequate and we may be required to devote additional resources to modifying or enhancing our systems in the future. Furthermore, while we maintain insurance intended to address costs associated with aspects of cyber incidents, network failures and data privacy-related concerns, our coverage may not sufficiently cover all types of losses or claims that may arise.

If we do not adapt to new technologies implemented by our competitors in the LTL and transportation industry, our business could suffer.

The LTL and transportation industry may be impacted by rapid changes in technologies. Our competitors may implement new technology that could improve their service, price, available capacity or business relationships and increase their market share. If we do not appropriately adapt our operations to these new technologies, our business, financial condition, and results of operations may suffer.

Failure to keep pace with developments in technology, any disruption to our technology infrastructure, or failures of essential services upon which our technology platforms rely could cause us to incur costs or result in a loss of business, which may have a material adverse effect on our results of operations and financial condition.

We rely heavily on information technology systems. Our information technology systems are complex and require ongoing investments and enhancements to meet both internal requirements and the requirements of our customers. If we are unable to invest in and enhance or modernize our technology systems in a timely manner or at a reasonable cost, or if we are unable to train our employees to operate the new, enhanced or modernized systems, our results of operations and financial condition could be adversely affected. We also may not achieve the benefits that we anticipate from any new technology or new or modernized system, and a failure to do so could result in higher than anticipated costs or adversely affect our results of operations.

Our information technology systems also depend upon the Internet, third-party service providers, global communications providers, satellite-based communications systems, the electric utilities grid, electric utility providers and telecommunications providers. We have minimal control over the operation, quality, or maintenance of these services or whether vendors will improve their services or continue to provide services that are essential to our business. Disruptions due to transitional challenges in upgrading or enhancing our technology systems; failures in the services upon which our information technology platforms rely, including those that may arise from adverse weather conditions or natural calamities, such asincluding but not limited to floods, hurricanes, earthquakes or tornadoes; illegal acts, including terrorist attacks; human error or systems modernization initiatives; and/or other disruptions, may adversely affect our business, which could increase our costs or result in a loss of customers that could have a material adverse effect on our results of operations and financial position.condition.

DamageRisks Related to Legal and Regulatory Matters

The FMCSA’s CSA initiative could adversely impact our reputationability to hire qualified drivers, meet our growth projections and maintain our customer relationships, each of which could adversely impact our results of operations.

The FMCSA’s Compliance, Safety, Accountability initiative (“CSA”) is an enforcement and compliance program designed to monitor and improve commercial motor vehicle safety by measuring the safety record of both the motor carrier and the driver. These measurements are scored and used by the FMCSA to identify potential safety risks and to direct enforcement action.

Our CSA scores are dependent upon our safety and compliance experience, which could change at any time. In addition, the safety standards prescribed in CSA could change and our ability to maintain an acceptable score could be adversely impacted. Public disclosure of certain CSA scores was restricted through the enactment of the Fixing America’s Surface Transportation Act of 2015 (the “FAST Act”) on December 4, 2015; however, the FAST Act does not restrict public disclosure of all data collected by the FMCSA. The FMCSA is currently reviewing CSA methodology to address deficiencies identified by the National Academy of Sciences, including the possibility of weak or negative correlation between current safety improvement categories and vehicle crash risk. Nevertheless, if we receive unacceptable CSA scores, and this data is made available to the public, our relationships with our customers could be damaged, which could result in a loss of business.

The requirements of the CSA could also shrink the industry’s pool of drivers, as those with unfavorable publicityscores could leave the industry. As a result, the costs to attract, train and retain qualified drivers could increase. In addition, a shortage of qualified drivers could increase driver turnover, decrease asset utilization, limit growth and adversely impact our results of operations.

We operate in a highly regulated industry, and increased costs of compliance with, or liability for violation of, existing or future regulations could have a material adverse effect on our business.

We are regulated by the DOT and by various state and federal agencies. These regulatory authorities have broad powers over matters relating to authorized motor carrier operations, as well as motor carrier registration, driver hours of service, safety and fitness of transportation equipment and drivers, transportation of hazardous materials, certain mergers and acquisitions and periodic financial reporting. The trucking industry is also subject to regulatory and legislative changes from a variety of other governmental authorities, which address matters such as increasingly stringent environmental regulations, occupational safety and health regulations, limits on vehicle weight and size, ergonomics, port security, and driver hours of service. We are also subject to the costs and potential adverse impact of compliance associated with FMCSA’s ELD regulations and guidance, including the operation of our fleet and safety management systems on the ELD hardware and software platform. In addition, we are subject to compliance with cargo-security and transportation regulations issued by the TSA and CBP within the U.S. Department of Homeland Security. Regulatory requirements and changes in regulatory requirements or guidance, together with the growing compliance risks presented by increased differences between applicable federal and state regulations, may affect our business or the economics of the industry by requiring changes in operating practices that could influence the demand for and increase the costs of providing transportation services.

We are subject to various governmental laws and regulations, and costs of compliance with, liabilities under, or violations of, existing or future governmental laws or regulations could adversely affect our business.

We are subject to various federal, state and local environmental laws and regulations that govern, among other things, the disposal, emission and discharge of hazardous waste, hazardous materials, or other materials into the environment, their presence at our properties or in our vehicles, fuel storage tanks, the transportation of certain materials and the discharge or retention of storm water. Under specific environmental laws, we could also be held responsible for any costs relating to contamination at our past or present facilities and at third-party waste disposal sites, as well as costs associated with the clean-up of accidents involving our vehicles. Environmental laws have become and may continue to be increasingly more stringent over time, and there can be no assurance that our costs of complying with current or future environmental laws or liabilities arising under such laws will not have a material adverse effect on our business, operations or financial condition.

In the current environment of instantaneous communication and social media outlets, the quick and broad dissemination of information through media sources could cause damaging information about us, whether accurateWe may be adversely affected by legal, regulatory, or not,market responses to be broadly publicized.  Unfavorable publicity about us or our employees could damage our reputationclimate change concerns.

Increased concern over climate change and the valuepotential impact of global warming has led to an increase in the Old Dominion brandconsideration of greenhouse gas emissions regulation. Due to increased consideration, there could be an increase in regulation from federal, state and local governments related to our carbon footprint, including with respect to vehicle engine and facility 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. Finally, given the increasing focus on ESG matters by the investor community, if shareholders were to express dissatisfaction with our policies or efforts with respect to climate change, sustainability or similar matters, there could be a reduction in demand fornegative impact on our services or the loss of customers.

Healthcare legislation and other mandated benefits-related coverage may increase our costs for us toemployee healthcare and benefits and reduce our future profitability.

To attract and retain customersemployees, we maintain a competitive and comprehensive benefits plan for our employees and their dependents. We cannot predict the impact that any state or requirefederal healthcare or mandated benefit legislation or regulation will have on our operations, but we expect costs associated with providing benefits under employee medical plans, paid sick and family leave programs and healthcare-related costs associated with workers’ compensation to continue to increase. Rising employee benefits and healthcare costs in the U.S. could result in significant long-term costs to us, to allocate significant resources to the rebuilding of our reputation and brand, any of which could have a material adverse effect on our operating results. In addition, rising employee benefits and health-related costs could force us to make further changes to our benefits program, which could negatively impact our ability to attract and retain employees.

We are subject to the risks of litigation and governmental proceedings, inquiries, notices or investigations which could adversely affect our business.

The nature of our business exposes us to the potential for various claims and litigation related to labor and employment, personal injury, property damage, cargo claims, safety and contract compliance, environmental liability and other matters. Accordingly, we are, and in the future may be, subject to legal proceedings and claims that have arisen in the ordinary course of our business, and may include collective and/or class action allegations. We are also subject to potential governmental proceedings, inquiries, notices or investigations, which also exposes us to the potential for various claims and litigation. The parties in such actions may seek amounts from us that may not be covered in whole or in part by insurance. Defending ourselves against such actions could result in significant costs and could require a substantial amount of time and effort by our management team. We cannot predict the outcome of litigation or governmental proceedings, inquiries, notices or investigations to which we are a party or whether we will be subject to future legal actions. As a result, the potential costs associated with any such legal actions against us could adversely affect our business, financial condition andor results of operations.

The Congdon family controls a large portion of our normal replacement cycle each year, we rely onoutstanding common stock.

David S. Congdon, John R. Congdon, Jr. and their affiliate family members beneficially own an aggregate of approximately 18% of the used equipment market to dispose of our older equipment. Oversupply in the transportation industry as well as adverse domestic and foreign economic conditions can negatively impact the demand for used equipment and, therefore, reduce the value we can obtain on our used equipment. If we are unable to sell our older equipment at or above our salvage value, the resulting losses could have a significant impact on our results of operations.

If we raise additional capital in the future, your ownership in us could be diluted.

There can be no assurance of our ability to declare and pay cash dividends in future periods.

We intend to pay a quarterly cash dividend to holders of our common stock for the foreseeable future; however, dividend payments are subject to approval by our Board of Directors, and are restricted by applicable state law limitations on distributions to shareholders as well as certain covenants under our revolving credit facility.facility and our note purchase and private shelf agreement. As a result, future dividend payments are not guaranteed and will depend upon various factors such as our overall financial condition, available liquidity, anticipated cash needs, future prospects for earnings and cash flows, as well as other factors considered relevant by our Board of Directors. In addition, any reduction or suspension in our dividend payments could adversely affect the price of our common stock.

The amount and frequency of our stock repurchases may fluctuate.

The amount, timing and execution of our stock repurchase program may fluctuate based on our strategic approach and our priorities for the use of cash. Other factors that may impact share repurchases include changes in stock price, profitability, capital structure, or cash flows. Our revolving credit facility and our note purchase and private shelf agreement also include provisions that may limit our ability to make payments for share repurchases. We may also use cash for investing in strategic assets or dividend payments, instead of share repurchases.

The market value of our common stock has recently been and may in the future be volatile, and could be substantially affected by various factors.

The price of our common stock on the Nasdaq Global Select Market changes constantly. We expect that the market price of our common stock will continue to fluctuate due to a variety of factors, many of which are beyond our control. These factors include, among others:

Our common stock price may continue to fluctuate significantly in the future, and these fluctuations may be unrelated to our performance. General market price declines or market volatility in the future could adversely affect the price of our common stock, and the current market price of our common stock may not be indicative of future market prices.

We believe that all of our properties are in good repair and are capable of providing the level of service required by current business levels and customer demands. In addition, we believe we have sufficient capacity in our service center network to accommodate increased demand for our services.

ITEM 3. LEGAL PROCEEDINGS

We are involved in or addressing various legal proceedings and claims, governmental inquiries, notices and investigations that have arisen in the ordinary course of our business and have not been fully adjudicated, some of which may be covered in whole or in part by insurance. Certain of these matters include collective and/or class-action allegations. We do not believe that the resolution of any of these matters will have a material adverse effect upon our financial position, results of operations or cash flows.

Consistent with SEC Regulation S-K Item 103, we have elected to disclose those environmental legal proceedings with a governmental authority if management reasonably believes that the proceedings may involve potential monetary sanctions of $1,000,000 or more. The following matter is disclosed in accordance with that requirement. We do not believe that any possible loss that may be incurred in connection with the matter will be material to our financial position, results of operations or cash flows.

On May 12, 2017, we received a letter from the Orange County California District Attorney’s Office concerning suspected violations of California laws with respect to waste handling practices. As part of the civil investigation conducted in coordination with other California counties, we have shared information about our waste handling practices at our facilities throughout the state. We are in discussions concerning resolution of this matter.

Overview

We are a leading,one of the largest North American less-than-truckload (“LTL”), union-free motor carrier providingcarriers. We provide regional, inter-regional and national LTL services through a single integrated, union-free organization. Our service offerings, which include expedited transportation, are provided through an expansive network of service centers located throughout the continental United States. Through strategic alliances, we also provide LTL services throughout North America. In addition to our core LTL services, we offer a range of value-added services including container drayage, truckload brokerage and supply chain consulting. More than 97%98% of our revenue has historically been derived from transporting LTL shipments for our customers, whose demand for our services is generally tied to industrial production and the overall health of the U.S. domestic economy.

In analyzing the components of our revenue, we monitor changes and trends in our LTL services using the following key metrics, which exclude certain transportationvolumes and logistics services where pricing is generally not determined by weight, commodity or distance:

Revenue per hundredweight is a yield measurement, it is also a commonly-used indicator offor general pricing trends but thisin the LTL industry. This yield metric is not a true measure of price, however, as it can be influenced by many other factors, such as changes in fuel surcharges, weight per shipment and length of haul and the class, or mix, of our freight.haul. As a result, changes in revenue per hundredweight do not necessarily indicate actual changes in underlying base rates.
