PART I

Overview

We have strategically transitioned from a refrigerated long-haul carrier to a multifaceted business offering a network of time and temperature-sensitive and dry truck-based transportation and distribution capabilities across our five distinct business platforms – Truckload, Dedicated, Intermodal, Brokerage and MRTN de Mexico. We are one of the leading temperature-sensitive truckload carriers in the United States, specializing in transporting and distributing food and other consumer packaged goods that require a temperature-controlled or insulated environment. In 2023, we generated $1.131 billion in operating revenue. Approximately 58% of our Truckload and Dedicated revenue in 2023 resulted from hauling temperature-sensitive products and 42% from hauling dry freight. We operate throughout the United States and in parts of Mexico and Canada, with our revenue primarily generated from within the United States. We provide regional truckload carrier services in the Southeast, West Coast, Midwest, South Central and Northeast regions. Our primary medium-to-long-haul traffic lanes are between the Midwest and the West Coast, Southwest, Southeast, and the East Coast, as well as from California to the Pacific Northwest. In 2023, our average length of haul was 414 miles.

Our growth strategy is to expand our business organically by offering shippers a high level of service and significant freight capacity. We market primarily to shippers that offer consistent volumes of freight in the lanes we prefer and are willing to compensate us for a high level of service. With our fleet of 3,349 company and independent contractor tractors, we offer service levels that include up to 99% on-time performance and delivery within the narrow time windows often required when shipping perishable commodities.

We have four reporting segments – Truckload, Dedicated, Intermodal and Brokerage. Financial information regarding these segments can be found in Footnote 14 to the Notes to Consolidated Financial Statements under Item 8 of this Form 10-K.

Our Truckload segment provides a combination of regional short-haul and medium-to-long-haul full-load transportation services. We transport food and other consumer packaged goods that require a temperature-controlled or insulated environment, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for one year.

Our Dedicated segment provides customized transportation solutions tailored to meet each individual customer’s requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from three to five years and are subject to annual rate reviews.

Our Intermodal segment transports our customers’ freight within the United States utilizing our refrigerated containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers.

Our Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. We retain the billing, collection and customer management responsibilities.

Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.

Organized under Wisconsin law in 1970, we are a successor to a sole proprietorship Roger R. Marten founded in 1946. In 1988, we reincorporated under Delaware law. Our executive offices are located at 129 Marten Street, Mondovi, Wisconsin 54755. Our telephone number is (715) 926-4216.

We maintain a website at www.marten.com. We are not including the information contained on our website as a part of, nor incorporating it by reference into, this Annual Report on Form 10-K. We post on our website, free of charge, documents that we file with or furnish to the SEC, including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and proxy statements, as soon as reasonably practicable after we electronically file such material with, or furnish such material to, the SEC. We also provide a link on our website to Forms 3, 4 and 5 that our officers, directors and 10% stockholders file with the SEC pursuant to Section 16(a) of the Securities Exchange Act of 1934.

Marketing and Operations

We approach our business as an integrated effort of marketing and operations. We target food and consumer packaged goods companies whose products require temperature-sensitive services and who ship multiple truckloads per week. By emphasizing high-quality service, we seek to become a core carrier for our customers. In 2023, our largest customer was Walmart.

Our marketing efforts are conducted by a staff of 290 sales, customer service and support personnel under the supervision of our senior management team. Marketing personnel travel within their regions to solicit new customers and maintain contact with existing customers. Customer service managers regularly contact customers to solicit additional business on a load-by-load basis.

Our operations and sales personnel strive to improve our asset productivity by seeking freight that allows for rapid turnaround times, minimizes non-revenue miles between loads and carries a favorable rate structure. Once we have established a customer relationship, customer service managers work closely with our fleet managers to match customer needs with our capacity and the location of revenue equipment. Fleet managers use our optimization system to assign loads to satisfy customer and operational requirements, as well as to meet the routing needs of our drivers. We attempt to route most of our trucks over selected operating lanes, which we believe assists us in meeting customer requirements, balancing traffic, reducing non-revenue miles, and improving the reliability of delivery schedules.

We employ technology in our operations when we believe that it will allow us to operate more efficiently and the investment is cost-justified. Examples of the technologies we employ include:

We believe this integrated approach to our marketing and operations, coupled with our use of technology, has allowed us to provide our customers with a high level of service and support our revenue growth in an efficient manner. For example, we produced a non-revenue mile percentage of 7.3% during 2023, which points to the efficiency of our operations and we believe compares favorably to other temperature-sensitive and dry van trucking companies.

Major Customers

A significant portion of our revenue is generated from our major customers. In 2023, our top 30 customers accounted for approximately 69% of our revenue excluding fuel surcharges, and our top ten customers accounted for 47% of our revenue. We have emphasized increasing our customer diversity which is shown by the decrease in the portion of our revenue with our top customers. In 2010, our top 30 customers accounted for approximately 78% of our revenue. Nine of our top ten customers have been significant customers of ours for the last ten years. We believe we are the largest or second largest temperature-sensitive carrier for seven of our top ten customers. We believe our relationships with these key customers are sound, but we are dependent upon them and the loss of some or all of their business could have a materially adverse effect on our results.

Human Capital

As of December 31, 2023, we had 4,213 employees. This total consists of 3,256 drivers, 303 mechanics and maintenance personnel, and 654 support personnel, which includes management and administration. As of that date, we also contracted with 94 independent contractors. None of our employees are represented by a collective bargaining unit. We consider relations with our employees to be good.

We believe our employees are a critical part to the continued success of our operations. Our business model depends on the efforts of our support personnel to efficiently and effectively coordinate transportation services for our customers and on the efforts of our drivers to timely and safely execute the delivery of our customers’ cargo. Competition in the trucking industry for qualified drivers is normally intense and has increased. Our operations have been impacted by, and from time-to-time we have experienced under-utilization and increased expense relating to, a shortage of qualified drivers. As such, we dedicate significant attention to hiring and retaining talented employees to manage, support and execute our operations and place a high priority on the recruitment and retention of an adequate supply of qualified drivers, and on minimizing turnover of our company-employed drivers and independent contractors. As part of those efforts, we are also committed to hiring, developing and supporting a diverse and inclusive workplace.

We believe we provide our employees with compensation and benefits that are competitive with or exceed our industry peers. We primarily pay company-employed drivers a fixed rate per mile. The rate increases based on length of service. We also compensate drivers for all detention time, for inclement weather and for road service delays. Total weekly compensation is also subject to a guaranteed minimum amount. We pay independent contractors a fixed rate per mile. Independent contractors pay for their own fuel, insurance, maintenance and repairs.

The health and well-being of our employees is paramount to our success. We sponsor a wellness program designed to enhance the well-being of each of our employees. The COVID-19 pandemic has also heightened our responsibility of ensuring our employees have a safe work environment and we have implemented numerous efforts to keep our valued employees safe, healthy and informed. We believe that maintaining a healthy, safe and productive professional driver group is essential to providing excellent customer service and achieving profitability. We select drivers, including independent contractors, using our specific guidelines for safety records, including drivers’ Compliance, Safety, Accountability, or CSA, scores, driving experience and personal evaluations. We maintain stringent screening, training and testing procedures for our drivers to reduce the potential for accidents and the corresponding costs of insurance and claims. We train new drivers at a number of our terminals in all phases of our policies and operations, as well as in safety techniques and fuel-efficient operation of the equipment. All new drivers also must pass DOT required tests prior to assignment to a vehicle.

Revenue Equipment

Our revenue equipment programs are an important part of our overall goal of profitable growth. We evaluate our equipment decisions based on factors such as initial cost, useful life, warranty terms, expected maintenance costs, fuel economy, driver comfort, customer needs, manufacturer support and resale value. We generally operate newer, well-maintained equipment with uniform specifications to minimize our spare parts inventory, streamline our maintenance program and simplify driver training.

As of December 31, 2023, we operated a fleet of 3,349 tractors, including 3,255 company-owned tractors and 94 tractors supplied by independent contractors. The average age of our company-owned tractor fleet at December 31, 2023 was approximately 1.9 years. In 2023, we replaced our company-owned tractors within an average of 4.1 years after purchase.

Kenworth and Freightliner manufacture most of our company-owned tractors. Maintaining a relatively new and standardized fleet allows us to operate most miles while the tractors are under warranty to minimize repair and maintenance costs. It also enhances our ability to attract drivers, increases fuel economy and improves customer acceptance by minimizing service interruptions caused by breakdowns. We adhere to a comprehensive maintenance program during the life of our equipment. We perform most routine servicing and repairs at our terminal facilities to reduce costly on-road repairs and out-of-route trips. We do not have any agreements with tractor manufacturers pursuant to which they agree to repurchase the tractors or guarantee a residual value, and we therefore could incur losses upon disposition if resale values of used tractors decline.

We historically have contracted with independent contractors to provide and operate a portion of our tractor fleet. Independent contractors own their own tractors and are responsible for all associated expenses, including financing costs, fuel, maintenance, insurance and taxes. The percentage of our fleet provided by independent contractors was 2.8% at December 31, 2023, 2.6% at December 31, 2022 and 2.9% at December 31, 2021.

As of December 31, 2023, we operated a fleet of 5,653 trailers, consisting of 3,347 refrigerated trailers and 2,306 dry vans. Most of our refrigerated trailers are equipped with Thermo-King refrigeration units, air ride suspensions and anti-lock brakes. The average age of our trailer fleet at December 31, 2023 was approximately 4.6 years. In 2023, we replaced our company-owned trailers within an average of 8.0 years after purchase.

As of December 31, 2023, we operated a fleet of 787 refrigerated containers for use on railroad flatcars as compared to a fleet of 802 refrigerated containers as of December 31, 2022.

Insurance and Claims

We self-insure for a portion of our claims exposure resulting from workers’ compensation, auto liability, general liability, cargo and property damage claims, as well as employees’ health insurance. We are responsible for our proportionate share of the legal expenses relating to such claims as well. We reserve currently for anticipated losses and expenses. We periodically evaluate and adjust our insurance and claims reserves to reflect our experience. We have $20.7 million in standby letters of credit to guarantee settlement of claims under agreements with our insurance carriers and regulatory authorities. We maintain insurance coverage for per-incident and total losses in excess of the amounts for which we self-insure up to specified policy limits with licensed insurance carriers. Insurance carriers have significantly raised premiums for trucking companies, which increases our insurance and claims expense, along with other factors. We believe that our policy of self-insuring up to set limits, together with our safety and loss prevention programs, are effective means of managing insurance costs.

Fuel

Our operations are heavily dependent upon the use of diesel fuel. The price and availability of diesel fuel can vary and are subject to political, economic and market factors that are beyond our control. Fuel prices fluctuated dramatically and quickly at various times during the last three years. We actively manage our fuel costs by purchasing fuel in bulk at a number of our facilities throughout the country and have volume purchasing arrangements with national fuel centers that allow our drivers to purchase fuel at a discount while in transit. During 2023, nearly 100% of our fuel purchases were made at these designated locations. To help further reduce fuel consumption, we have equipped our company-owned tractors with auxiliary power units since 2007. These units reduce fuel consumption by providing quiet climate control and electrical power for our drivers without idling the tractor engine. We have also invested in terrestrial-based tracking equipment for the temperature-control units on our trailers that has improved fuel usage through management of required temperature settings and run time of the units.

We further manage our exposure to changes in fuel prices through fuel surcharge programs with our customers and other measures that we have implemented. We have historically been able to pass through a significant portion of long-term increases in fuel prices and related taxes to customers in the form of fuel surcharges. These fuel surcharges, which adjust with the cost of fuel, enable us to recover a substantial portion of the higher cost of fuel as prices increase, except for non-revenue miles, out-of-route miles or fuel used while the tractor is idling. As of December 31, 2023, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Competition

We are one of the leading carriers operating in the temperature-sensitive segment of the truckload market, and our dry freight services are expanding. These markets are highly competitive, and we compete with many other truckload carriers of varying sizes and, to a lesser extent, with less-than-truckload carriers, railroads, and other transportation companies, many of which have more equipment, a wider range of services and greater capital resources than we do or have other competitive advantages. We also compete with other motor carriers for the services of drivers, independent contractors and management employees. We believe that the principal competitive factors in our business are service, freight rates, capacity, use of technology and financial stability, which positions us well to compete in these segments.

Regulation

The DOT and various state and local agencies exercise broad powers over our business, generally governing such activities as authorization to engage in motor carrier operations, safety and insurance requirements. Our company drivers and independent contractors also must comply with the safety and fitness regulations promulgated by the DOT, including those relating to drug and alcohol testing, medical and continuous training qualification and hours-of-service.

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

The FMCSA issued final revisions to the hours-of-service requirements for drivers in September 2020. The revisions allow drivers more flexibility with their 30-minute rest breaks and with dividing their time in the sleeper berth. Additionally, the new regulations increase by two hours the duty time for drivers encountering adverse weather and expand the short haul exemption radius from 100 to 150 miles.

In January 2011, the FMCSA issued a regulatory proposal requiring commercial carriers to track compliance with hours-of-service regulations using electronic logging devices, or ELD’s, which was vacated and sent back to the FMCSA for further analysis and review in September 2011 by the 7^th U.S. Circuit Court of Appeals. The Moving Ahead for Progress in the 21^st Century Act, or MAP-21 Act, included a provision directing the FMCSA to develop a final ELD rule in 2013, which was delayed until its issuance in December 2015. The final rule required compliance beginning in December 2017 which was strictly enforced beginning in April 2018. Carriers using automatic on-board recording devices, or AOBRD’s, which were installed and in use prior to December 2017 were allowed until December 2019 to convert to ELD’s. Our entire fleet was equipped with AOBRD’s since early 2011 and converted to ELD’s prior to December 2019.

The FMCSA has established a Commercial Driver’s License Drug and Alcohol Clearinghouse, which is a database of drivers who have violations including failed or refused drug and alcohol tests. Beginning in January 2020, all carriers are required to run queries in the clearinghouse for all prospective drivers and annually for all drivers currently employed. All testing violations must also be reported to the clearinghouse. Also effective in January 2020, all carriers must perform random drug tests at a rate of at least 50% of the average number of driver positions. The rate was at least 25% previously. We have been testing at a rate in excess of 50%, including when the requirement was at least 25%, and tested 55% in 2021, 57% in 2022 and 67% in 2023. The impact of the clearinghouse has been significant, with a total of approximately 158,000 drivers removed from the trucking industry from January 2020 through December 2023.

In September 2020, the United States Department of Health and Human Services proposed mandatory guidelines for federal workplace drug testing programs using hair follicles, which is a more strenuous test than current requirements. The FMCSA has not issued proposed regulations.

We are also subject to various environmental laws and regulations dealing with vehicle emissions and idling, the handling of hazardous materials, fuel storage tanks, air emissions from our facilities and discharge and retention of storm water. These regulations did not have a significant impact on our operations or financial results in 2021 through 2023.

The following factors are important and should be considered carefully in connection with any evaluation of our business, financial condition, results of operations, prospects or an investment in our common stock. The risks and uncertainties described below are those that we currently believe may materially affect our company or our financial results. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations or affect our financial results.

Risks Related to Our Industry and Operations

Our business is subject to general economic and business factors that are largely beyond our control, any of which could have a materially adverse effect on our operating results. Our business is dependent on a number of general economic and business factors that may have a materially adverse effect on our results of operations, many of which are beyond our control. These factors include excess capacity in the trucking industry, strikes or other work stoppages, and significant increases or fluctuations in interest rates, fuel taxes, fuel prices and license and registration fees. We are affected by recessionary economic cycles and downturns in customers’ business cycles, particularly in market segments and industries where we have a significant concentration of customers. Economic conditions may adversely affect our customers and their ability to pay for our services.

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

We operate in a highly competitive and fragmented industry, and numerous competitive factors could impair our ability to maintain our current profitability. We compete with many other truckload carriers that provide temperature-sensitive service and dry freight of varying sizes and, to a lesser extent, with less-than-truckload carriers, railroads and other transportation companies, many of which have more equipment, a wider range of services and greater capital resources than we do or have other competitive advantages. Many of our competitors periodically reduce their freight rates to gain business, especially during times of reduced growth rates in the economy, which may limit our ability to maintain or increase freight rates or maintain significant growth in our business. In addition, many customers reduce the number of carriers they use by selecting so-called “core carriers” as approved service providers or conduct bids from multiple carriers for their shipping needs, and in some instances, we may not be selected as a core carrier or to provide service under such bids.

In addition, the trend toward consolidation in the trucking industry may create other large carriers with greater financial resources and other competitive advantages relating to their size. Competition from freight logistics and brokerage companies may negatively impact our customer relationships and freight rates. Furthermore, economies of scale that may be passed on to smaller carriers by procurement aggregation providers may improve such carriers’ ability to compete with us.

If the growth in our regional operations declines, or if we expand into a market with insufficient economic activity, our results of operations could be adversely affected. We operate regional service centers which are located in a number of cities within the United States. In order to support future growth, these regional operations require the commitment of additional capital, revenue equipment and facilities along with qualified management, drivers and other personnel. Should the growth in our regional operations decline, the results of our operations could be adversely affected. It may become more difficult to identify additional cities that can support service centers, and we may expand into cities where there is insufficient economic activity, reduced capacity for growth or less driver and non-driver personnel to support our operations. We may encounter operating conditions in these new markets that materially differ from our current operations and customer relationships may be difficult to obtain at appropriate freight rates. Also, we may not be able to apply our regional operating strategy successfully in additional cities, and it might take longer than expected or require a more substantial financial commitment than anticipated to establish our operations in the additional cities.

Lack of capacity, changes in equipment requirements and service instability in the railroad industry could increase our operating costs and reduce our ability to offer intermodal services, which could adversely affect our revenue, results of operations and customer relationships. Our Intermodal segment is dependent on railroad services and their capacity to transport freight for our customers. We expect our dependence on railroads will continue to increase as we expand our intermodal services. We compete for the availability of railroad services with other intermodal operators as well as certain industries reliant on the use of rail cars, such as oil and agricultural, whose consumption of railroad capacity has significantly fluctuated over the past several years. In most markets, rail service is limited to a few railroads or even a single railroad. Any capacity constraints, changes in equipment requirements, threatened or actual rail worker strikes, service problems or reduction in service by the railroads with which we have, or in the future may have, relationships is likely to increase the cost of the rail-based services we provide and reduce the reliability, timeliness and overall attractiveness of our rail-based services, which could adversely affect our revenue, results of operations and customer relationships. Furthermore, railroads are relatively free to adjust shipping rates up or down as market conditions permit. Price increases could result in higher costs to our customers and reduce or eliminate our ability to offer intermodal services. In addition, we cannot assure you that we will be able to negotiate additional contracts with railroads to expand our capacity, add additional routes or obtain multiple providers, which could limit our ability to provide this service.

Increased prices and restricted availability of new revenue equipment could cause our financial condition, results of operations and cash flows to suffer. We have experienced higher prices for new tractors and trailers over the past few years, primarily as a result of higher commodity prices and government regulations applicable to newly manufactured tractors and trailers. We expect to continue to pay increased prices for revenue equipment for the foreseeable future. Our business could be harmed if we are unable to continue to obtain an adequate supply of new tractors and trailers or if we are required to pay increased prices for new revenue equipment.

We derive a significant portion of our revenue from our major customers, the loss of one or more of which could have a materially adverse effect on our business. A significant portion of our revenue is generated from our major customers. For 2023 our top 30 customers, based on revenue excluding fuel surcharges, accounted for approximately 69% of our revenue; our top ten customers accounted for approximately 47% of our revenue; our top five customers accounted for approximately 35% of our revenue; our top two customers accounted for approximately 27% of our revenue; and our largest customer accounted for approximately 19% of our revenue. Generally, other than for our Dedicated operations, we enter into one-year contracts with our major customers, the majority of which do not contain any firm obligations to ship with us. We cannot ensure that, upon expiration of existing contracts, these customers will continue to use our services or that, if they do, they will continue at the same levels. Many of our customers periodically solicit bids from multiple carriers for their shipping needs, and this process may depress freight rates or result in loss of business to our competitors. Some of our customers also operate their own private trucking fleets, and they may decide to transport more of their own freight. A reduction in or termination of our services by one or more of our major customers could have a materially adverse effect on our business and operating results.

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

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

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

We depend on the stability, availability and security of the technology related to our management information and communication systems, which are subject to certain cyber risks and other events beyond our control. We depend upon our management information and communication systems for the efficient operation of our business. Our systems are used for receiving, planning and optimizing loads, communicating with and monitoring our drivers, tractors and trailers, billing customers and financial reporting. In addition, some of our key software has been developed internally by our programmers or by adapting purchased software to our needs and this software may not be easily modified or integrated with other software and systems. Our operations are potentially vulnerable to interruption by natural disasters, power loss, telecommunications failure, terrorist attacks, internet failures, computer viruses, malware, hacking and other events beyond our control. Although we have taken steps to prevent and mitigate service interruptions and data security threats, the operational and security risks associated with information technology systems have increased in recent years because of the complexity of the systems and the sophistication and increasing volume of cyberattacks. We have been subject to cyberattacks, which have yet to have a material impact on our business or results of operations, but this might not always be the case in the future. For example, as previously reported, in October 2021, we detected a cyberattack that accessed and encrypted files utilized by us in the operation of our business. The incident did not have a material impact on our business, operations or financial results. Nonetheless, certain employee data was at risk during the event. Our business could be materially and adversely affected if our management information and communication systems are materially compromised or disrupted by a failure or security breach, or if we are unable to improve, upgrade, integrate or expand our systems as we continue to execute our growth strategy. In addition, there has also been heightened regulatory focus on data protection, and failure to comply with applicable data protection regulations or other data protection standards may expose us to litigation, fines, sanctions or other penalties, which could harm our reputation and adversely impact our business, results of operations and financial condition.

Fluctuations in the price or availability of fuel may increase our cost of operation, which could materially and adversely affect our profitability. We require large amounts of diesel fuel to operate our tractors and to power the temperature-control units on our trailers. Fuel is one of our largest operating expenses. Fuel prices tend to fluctuate, and prices and availability of all petroleum products are subject to political, economic and market factors that are beyond our control. We depend primarily on fuel surcharges, auxiliary power units for our tractors, terrestrial-based tracking equipment for the temperature-control units on our trailers, volume purchasing arrangements with truck stop chains and bulk purchases of fuel at our terminals to control and recover our fuel expenses. There can be no assurance that we will be able to collect fuel surcharges, enter into volume purchase agreements or execute successful hedges in the future. Additionally, we may encounter decreases in productivity that may offset or eliminate savings from auxiliary power units or terrestrial-based tracking equipment, or we may incur unexpected maintenance or other costs associated with such units. The absence of meaningful fuel price protection through these measures, fluctuations in fuel prices or a shortage of diesel fuel could materially and adversely affect our results of operations.

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

Seasonality and the impact of weather can affect our profitability. Our tractor productivity generally decreases during the winter season because inclement weather impedes operations and some shippers reduce their shipments. At the same time, operating expenses generally increase, with harsh weather creating higher accident frequency, increased claims and more equipment repairs. We can also suffer short-term impacts from weather-related events such as hurricanes, blizzards, ice-storms and floods that could harm our results or make our results more volatile.

We are subject to risks associated with public health crises, such as pandemics and epidemics, including the COVID-19 pandemic, which could negatively impact our business and results of operations. While many countries around the world have removed or reduced the restrictions taken in response to the COVID-19 pandemic, the emergence of new variants of the COVID-19 virus may result in new governmental lockdowns, quarantine requirements or other restrictions to slow the spread of the virus. In addition, any such measures could also impact the global economy more broadly, for example, by leading to further economic slowdowns. While COVID-19 case volumes have decreased in the United States and certain other countries, the global outlook remains uncertain as case counts fluctuate and vaccination and booster rates remain relatively low in many parts of the world. The future impact of the pandemic continues to be an unknown. Although transportation services have been generally considered essential services and the overall demand for our services has continued throughout the pandemic, we did experience significant changes in demand from certain customers in certain freight lanes earlier in the pandemic. We are unable to predict if overall demand for our services will continue at current levels or decrease should an increase in the severity of the pandemic occur. We continue to monitor the pandemic’s impact on the health and safety of our employees, but any widespread outbreak among our employees due to an increase in the severity of the pandemic may negatively impact our business. Earlier in the pandemic, some of our customers encountered significant disruptions to their business. An increase in the severity of the pandemic could cause a similar impact for our customers, which could cause a greater risk for collection of amounts owed, potentially requiring us to increase our allowance for credit losses.

The scope and duration of any future public health crisis, including the potential emergence of new variants of the COVID-19 virus, the pace at which government restrictions are imposed and lifted, the scope of additional actions taken to mitigate the spread of disease, global vaccination and booster rates, the speed and extent to which global markets and utilization rates for our customers’ products fully recover from the disruptions caused by such a public health crisis, and the impact of these factors on our business, financial condition and results of operations, will depend on future developments that are highly uncertain and cannot be predicted with confidence.

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

Risks Related to Our Capital Requirements and Financing

We have significant ongoing capital requirements that could harm our financial condition, results of operations and cash flows if we are unable to generate sufficient cash from our operations. The truckload industry is capital intensive, and our policy of operating newer equipment requires us to expend significant amounts annually. If we elect to expand our fleet in future periods, our capital needs would increase. We expect to pay for projected capital expenditures with cash flows from operations and borrowings under our revolving credit facility. Significant increases or fluctuations in interest rates could have a materially adverse effect on such borrowings and our operating results. If we are unable to generate sufficient cash from operations and obtain financing on favorable terms in the future, we may have to limit our growth, enter into less favorable financing arrangements, or operate our revenue equipment for longer periods, any of which could have a materially adverse effect on our profitability.

Instability of the credit markets and the resulting effects on the economy could have a material adverse effect on our operating results. If the credit markets and the economy weaken, our business, financial results and results of operations could be materially and adversely affected, especially if consumer confidence declines and domestic spending decreases. We may need to incur indebtedness, which may include drawing on our credit facility, or issue debt securities in the future to fund working capital requirements, make investments or for general corporate purposes. Additionally, stresses in the credit market causes uncertainty in the equity markets, which may result in volatility of the market price for our securities.

Risks Related to Regulation of Our 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 materially adverse effect on our business. The DOT and various state and local agencies exercise broad powers over our business, generally governing such activities as authorization to engage in motor carrier operations, safety and insurance requirements. Our company drivers and independent contractors also must comply with the safety and fitness regulations promulgated by the DOT, including those relating to drug and alcohol testing, medical and continuous training qualification and hours-of-service. We also may become subject to new or more restrictive regulations relating to vehicle emissions, ergonomics or other matters affecting safety or operating methods. Other agencies, such as the United States Environmental Protection Agency, or EPA, and the United States Department of Homeland Security, or DHS, also regulate our equipment, operations and drivers. Future laws and regulations may be more stringent and require changes in our operating practices, influence the demand for transportation services or require us to incur significant additional costs. Higher costs incurred by us or by our suppliers who pass the costs onto us through higher prices could adversely affect our results of operations.

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

The FMCSA issued final revisions to the hours-of-service requirements for drivers in September 2020. The revisions allow drivers more flexibility with their 30-minute rest breaks and with dividing their time in the sleeper berth. Additionally, the new regulations increase by two hours the duty time for drivers encountering adverse weather and expand the short haul exemption radius from 100 to 150 miles.

In January 2011, the FMCSA issued a regulatory proposal requiring commercial carriers to track compliance with hours-of-service regulations using electronic logging devices, or ELD’s, which was vacated and sent back to the FMCSA for further analysis and review in September 2011 by the 7^th U.S. Circuit Court of Appeals. The Moving Ahead for Progress in the 21^st Century Act, or MAP-21 Act, included a provision directing the FMCSA to develop a final ELD rule in 2013, which was delayed until its issuance in December 2015. The final rule required compliance beginning in December 2017 which was strictly enforced beginning in April 2018. Carriers using automatic on-board recording devices, or AOBRD’s, which were installed and in use prior to December 2017 were allowed until December 2019 to convert to ELD’s. Our entire fleet was equipped with AOBRD’s since early 2011 and converted to ELD’s prior to December 2019.

The FMCSA has established a Commercial Driver’s License Drug and Alcohol Clearinghouse, which is a database of drivers who have violations including failed or refused drug and alcohol tests. Beginning in January 2020, all carriers are required to run queries in the clearinghouse for all prospective drivers and annually for all drivers currently employed. All testing violations must also be reported to the clearinghouse. Also effective in January 2020, all carriers must perform random drug tests at a rate of at least 50% of the average number of driver positions. The rate was at least 25% previously. We have been testing at a rate in excess of 50%, including when the requirement was at least 25%, and tested 55% in 2021, 57% in 2022 and 67% in 2023. The impact of the clearinghouse has been significant, with a total of approximately 158,000 drivers removed from the trucking industry from January 2020 through December 2023.

In September 2020, the United States Department of Health and Human Services proposed mandatory guidelines for federal workplace drug testing programs using hair follicles, which is a more strenuous test than the current requirements. The FMCSA has not yet issued proposed regulations.

From time to time, various federal, state or local taxes are increased, including taxes on fuels. We cannot predict whether, or in what form, any such increase applicable to us will be enacted, but such an increase could adversely affect our profitability.

Our operations are subject to various environmental laws and regulations, the violation of which could result in substantial fines or penalties. We are subject to various environmental laws and regulations dealing with vehicle emissions and idling, the handling of hazardous materials, fuel storage tanks, air emissions from our facilities and discharge and retention of storm water. We operate in industrial areas, where truck terminals and other industrial activities are located, and where groundwater or other forms of environmental contamination have occurred. Our operations involve the risks of fuel spillage or seepage, environmental damage and hazardous waste disposal, among others. Although we have instituted programs to monitor and control environmental risks and promote compliance with applicable environmental laws and regulations, if we are involved in a spill or other accident involving hazardous substances, or if we are found to be in violation of applicable laws or regulations, we could be subject to liabilities, including substantial fines or penalties or civil and criminal liability, any of which could have a materially adverse effect on our business and operating results.

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

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

Risks Related to Our Human Capital

Increases in compensation or difficulty in attracting drivers could affect our profitability and ability to grow. The transportation industry has historically experienced substantial difficulty in attracting and retaining qualified drivers, including independent contractors. With the current increased competition for drivers, including the impact that regulatory changes have had on the number of drivers in the transportation industry, we could experience greater difficulty in attracting sufficient numbers of qualified drivers. In addition, the available pool of independent contractor drivers is smaller than it has been historically. Accordingly, we may face difficulty in attracting and retaining drivers for all of our current tractors and for those we may add. Additionally, we may face difficulty in increasing the number of our independent contractor drivers. In addition, our industry suffers from high turnover rates of drivers. Our turnover rate requires us to recruit a substantial number of drivers. Moreover, our turnover rate could increase. If we are unable to continue to attract drivers and contract with independent contractors, we could be required to continue adjusting our driver compensation package or let trucks sit idle. An increase in our expenses or in the number of tractors without drivers could materially and adversely affect our growth and profitability.

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

None.

We have processes in place for assessing, identifying and managing material risks from cybersecurity threats. In order to assess and identify material risks from cybersecurity threats, we engage a third-party managed security service provider to conduct ongoing (24x7x365) security information and event management (SIEM) monitoring to collect, aggregate and analyze data from our applications, devices, servers and users in real-time to assist our security team in detecting and blocking cybersecurity attacks. In addition, we conduct periodic security vulnerability scans as well as external and internal penetration testing that simulate attacks on our computer systems to assist with the discovery and remediation of security flaws and vulnerabilities. Management continually reassesses our cybersecurity risk environment based on changing circumstances and new information identified by our monitoring, scanning and testing, as well as third party resources. Our processes for assessing, identifying and managing cybersecurity threats have been integrated into our overall risk management processes. The information provided by these processes facilitates management’s ongoing assessment of our cybersecurity risk environment and provides current and accurate information regarding cybersecurity risks to management, our Audit Committee and Board to allow appropriate management of such risks through remediation or other risk mitigation activities.

We engage various third-party cybersecurity service providers to assist with protection and monitoring of our systems and information, including with respect to protection of our e-mail and system access. These service providers are subject to an initial risk assessment as well as periodic risk assessments in order to evaluate, identify and mitigate risks from cybersecurity threats arising from our use of such service providers.

Although we have taken steps to prevent and mitigate service interruptions and data security threats, the operational and security risks associated with information technology systems have increased in recent years because of the complexity of the systems and the sophistication and increasing volume of cyberattacks. We have been subject to cyberattacks, which have yet to have a material impact on our business or results of operations, but this might not always be the case in the future. For example, as previously reported, in October 2021, we detected a cyberattack that accessed and encrypted files utilized by us in the operation of our business. The incident did not have a material impact on our business, operations or financial results. Nonetheless, certain employee data was at risk during the event. Our business could be materially and adversely affected if our management information and communication systems are materially compromised or disrupted by a failure or security breach, or if we are unable to safely improve, upgrade, integrate or expand our systems as we continue to execute our growth strategy. In addition, there has also been heightened regulatory focus on data protection, and failure to comply with applicable data protection regulations or other data protection standards may expose us to litigation, fines, sanctions or other penalties, which could harm our reputation and adversely impact our business, results of operations and financial condition.

Management is responsible for our day-to-day cybersecurity risk management and the Board’s responsibility is to engage in informed oversight of and provide overall direction with respect to such risk management. As part of its charter, the Audit Committee discusses with management and the independent auditors our adequacy and effectiveness of accounting and financial controls, including our systems to monitor and manage business, information technology and cybersecurity risks. On an annual basis, management prepares and presents to the Audit Committee a risk management summary that identifies risks by operational department (e.g., executive, finance, human resources, information systems, maintenance, operations, sales and marketing, risk management and safety), estimated maximum exposure per occurrence, the risk management option and insured level. The Board, its committees and management continually re-assess our cybersecurity risk environment based on changing circumstances and new information. The Audit Committee regularly discusses with management its enterprise risk management process, including our cybersecurity exposures, the steps management has taken to monitor and control such exposures and guidelines and policies to govern our risk assessment and risk management processes. The Audit Committee periodically reports to the Board regarding significant matters identified with respect to the foregoing, including, among others, our risk assessment and risk management approach to cybersecurity.

Our Executive Vice President and Chief Technology Officer, Randall Baier, is responsible for our day-to-day assessment and management of cybersecurity risks. Mr. Baier also served as our Senior Vice President of Information Systems from December 2019 to August 2023, our Vice President of Information Systems from January 2014 to December 2019 and our Senior Director of Information Systems from April 2011 to January 2014. Mr. Baier advanced through various professional capacities in our information technology area including Developer, System Administrator and Database Administrator from April 1993 to April 2011. We have implemented a number of processes which allow Mr. Baier and his team to be informed about and monitor the prevention, detection, mitigation and remediation of cybersecurity incidents. These processes include, among other things, system alerts of potential malicious cyber activity, access to real-time dashboards that monitor and assess our systems, status reports provided on a daily, weekly and monthly basis and regular ongoing communications with service providers regarding potential new attach vectors and vulnerabilities. Mr. Baier shares such information with our management team and reports information about such risks to the Audit Committee. 

Our executive offices and principal terminal are located on approximately seven acres in Mondovi, Wisconsin. This facility consists of 39,000 square feet of office space and 21,000 square feet of equipment repair and maintenance space. We added additional equipment repair and maintenance facilities in 2007 and in 2009 in Mondovi, Wisconsin which consist of 15,000 square feet of space located on approximately 11 acres and 50,000 square feet of space located on approximately three acres, respectively. We operate facilities in or near the following cities at which we primarily perform operations and maintenance activities:

Our Truckload, Dedicated and Brokerage segments operate out of a majority of our facilities while our Intermodal segment operates out of a small number of our locations. We believe the nature, size and location of our properties are suitable and adequate for our current business needs.

We are involved in ordinary routine litigation incidental to our operations. These lawsuits primarily involve claims for workers’ compensation, personal injury or property damage incurred in the transportation of freight.

PART II

Our common stock is listed on the NASDAQ Global Select Market under the symbol “MRTN.” On February 14, 2024, we had 155 record stockholders and approximately 20,096 beneficial stockholders of our common stock.

Dividend Policy

In 2010, we announced a regular cash dividend program to our stockholders, subject to approval each quarter. Quarterly cash dividends of $0.06 per share of common stock were paid in each quarter of 2023 which totaled $19.5 million. Quarterly cash dividends of $0.06 per share of common stock were paid in each quarter of 2022 which totaled $19.6 million. We paid cash dividends totaling $54.7 million in 2021 which consisted of a special dividend of $0.50 per share of common stock in October, along with quarterly cash dividends of $0.04 per share of common stock in March, June, October and December. We currently expect to continue to pay quarterly cash dividends in the future. The payment of cash dividends in the future, and the amount of any such dividends, will depend upon our financial condition, results of operations, cash requirements and certain corporate law requirements, as well as other factors deemed relevant by our Board of Directors.

Our credit agreement effective in August 2022 prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of $150 million. Our previous credit agreement prohibited us from making such payments in excess of 25% of our net income from the prior fiscal year. Waivers allowing stock redemptions and dividends in excess of the 25% limitation in total amounts of up to $80 million in each of 2022 and 2021 were obtained from the lender in March 2022 and August 2021, respectively. The current and previous credit agreements also contain restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at December 31, 2023 and December 31, 2022.

Share Repurchase Program

In August 2019, our Board of Directors approved and we announced an increase from current availability in our existing share repurchase program providing for the repurchase of up to $34.0 million, or approximately 1.8 million shares, of our common stock, which was increased by our Board of Directors to 2.7 million shares in August 2020 to reflect the three-for-two stock split effected in the form of a stock dividend on August 13, 2020. On May 3, 2022, our Board of Directors approved and we announced an additional increase from current availability in our existing share repurchase program providing for the repurchase of up to $50.0 million, or approximately 3.1 million shares, of our common stock. The share repurchase program allows purchases on the open market or through private transactions in accordance with Rule 10b-18 of the Exchange Act. The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does not have an expiration date.

We repurchased and retired 1.3 million shares of common stock for $25.0 million in the first quarter of 2022, and 963,000 shares of common stock for $16.8 million in the second quarter of 2022. We did not repurchase any shares in 2023, the third or fourth quarters of 2022, or in 2021. As of December 31, 2023, future repurchases of up to $33.2 million, or approximately 2.2 million shares, were available in the share repurchase program.

The following discussion and analysis of our financial condition and results of operations should be read together with the selected consolidated financial data and our consolidated financial statements and the related notes appearing elsewhere in this report. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those under the heading “Risk Factors” beginning on page 6. We do not assume, and specifically disclaim, any obligation to update any forward-looking statement contained in this report.

Overview

We have strategically transitioned from a refrigerated long-haul carrier to a multifaceted business offering a network of time and temperature-sensitive and dry truck-based transportation and distribution capabilities across our five distinct business platforms – Truckload, Dedicated, Intermodal, Brokerage and MRTN de Mexico.

Our Truckload segment provides a combination of regional short-haul and medium-to-long-haul full-load transportation services. We transport food and other consumer packaged goods that require a temperature-controlled or insulated environment, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for one year.

Our Dedicated segment provides customized transportation solutions tailored to meet each individual customer’s requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from three to five years and are subject to annual rate reviews.

Generally, we are paid by the mile for our Truckload and Dedicated services. We also derive Truckload and Dedicated revenue from fuel surcharges, loading and unloading activities, equipment detention and other accessorial services. The main factors that affect our Truckload and Dedicated revenue are the rate per mile we receive from our customers, the percentage of miles for which we are compensated, the number of miles we generate with our equipment and changes in fuel prices. We monitor our revenue production primarily through average Truckload and Dedicated revenue, net of fuel surcharges, per tractor per week. We also analyze our average Truckload and Dedicated revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our fuel surcharge revenue, our accessorial revenue and our other sources of operating revenue.

Our Intermodal segment transports our customers’ freight within the United States utilizing our refrigerated containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affect our Intermodal revenue are the rate per mile and other charges we receive from our customers.

Our Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. We retain the billing, collection and customer management responsibilities. The main factors that affect our Brokerage revenue are the rate per mile and other charges that we receive from our customers.

Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.

In addition to the factors discussed above, our operating revenue is also affected by, among other things, the United States economy, inventory levels, the level of truck and rail capacity in the transportation market, a contracting driver market, severe weather conditions and specific customer demand.

Our operating revenue decreased $132.4 million, or 10.5%, in 2023 from 2022. Our operating revenue, net of fuel surcharges, decreased $81.4 million, or 7.7%, compared with 2022. Truckload segment revenue, net of fuel surcharges, decreased 3.9% from 2022, primarily due to a decrease in our average revenue per tractor, despite an increase in our average fleet size. Dedicated segment revenue, net of fuel surcharges, decreased 0.6% from 2022, primarily due to a decrease in our average revenue per tractor. Intermodal segment revenue, net of fuel surcharges, decreased 24.5% from 2022, primarily due to decreases in both our number of loads and our revenue per load. Brokerage segment revenue decreased 19.0% from 2022, primarily due to decreases in both our revenue per load and our number of loads. Fuel surcharge revenue decreased to $159.4 million in 2023 from $210.4 million in 2022.

Our profitability is impacted by the variable costs of transporting freight for our customers, fixed costs, and expenses containing both fixed and variable components. The variable costs include fuel expense, driver-related expenses, such as wages, benefits, training and recruitment, and independent contractor costs, which are recorded under purchased transportation. Expenses that have both fixed and variable components include maintenance and tire expense and our cost of insurance and claims. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, fleet age, efficiency and other factors. Our main fixed costs relate to the acquisition and subsequent depreciation of long-term assets, such as revenue equipment and operating terminals. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of higher prices of new equipment, along with any increases in fleet size. Although certain factors affecting our expenses are beyond our control, we monitor them closely and attempt to anticipate changes in these factors in managing our business. For example, fuel prices have significantly fluctuated over the past several years. We manage our exposure to changes in fuel prices primarily through fuel surcharge programs with our customers, as well as through volume fuel purchasing arrangements with national fuel centers and bulk purchases of fuel at our terminals. To help further reduce fuel expense, we have installed and tightly manage the use of auxiliary power units in our tractors to provide climate control and electrical power for our drivers without idling the tractor engine, and also have improved the fuel usage in the temperature-control units on our trailers. For our Intermodal and Brokerage segments, our profitability is impacted by the percentage of revenue which is payable to the providers of the transportation services we arrange. This expense is included within purchased transportation in our consolidated statements of operations.

Our operating income declined 37.1% to $90.1 million in 2023 from $143.3 million in 2022. Our operating expenses as a percentage of operating revenue, or “operating ratio,” was 92.0% in 2023 and 88.7% in 2022. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, increased to 90.7% in 2023 from 86.4% in 2022. Our net income declined 36.2% to $70.4 million, or $0.86 per diluted share, in 2023 from $110.4 million, or $1.35 per diluted share, in 2022.

Our business requires substantial ongoing capital investments, particularly for new tractors and trailers. At December 31, 2023, we had $53.2 million of cash and cash equivalents, $757.4 million in stockholders’ equity and no long-term debt outstanding. In 2023, net cash flows provided by operating activities of $164.4 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $163.9 million, to pay cash dividends of $19.5 million and to construct and upgrade regional operating facilities in the amount of $8.6 million, resulting in a $27.4 million decrease in cash and cash equivalents. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $165 million in 2024. Quarterly cash dividends of $0.06 per share of common stock were paid in each quarter of 2023 which totaled $19.5 million. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

We continue to invest considerable time and capital resources to actively implement and promote long-term environmentally sustainable solutions that drive reductions in our fuel and electricity consumption and decrease our carbon footprint. These initiatives include (i) reducing idle time for our tractors by installing and tightly managing the use of auxiliary power units, which are powered by solar panels and provide climate control and electrical power for our drivers without idling the tractor engine, (ii) improving the energy efficiency of our newer, more aerodynamic and well-maintained tractor and trailer fleets by optimizing the equipment’s specifications, weight and tractor speed, equipping our tractors with automatic transmissions, converting the refrigeration units in our refrigerated trailers to the new, more-efficient CARB refrigeration units along with increasing the insulation in the trailer walls and installing trailer skirts, and using ultra-fuel efficient and wide-based tires, and (iii) upgrading all of our facilities to indoor and outdoor LED lighting along with converting all of our facilities to solar power. Additionally, we are an active participant in the United States Environmental Protection Agency, or EPA, SmartWay Transport Partnership, in which freight shippers, carriers, logistics companies and other voluntary stakeholders partner with the EPA to measure, benchmark and improve logistics operations to reduce their environmental footprint.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations includes discussions of operating revenue, net of fuel surcharge revenue; Truckload, Dedicated and Intermodal revenue, net of fuel surcharge revenue; operating expenses as a percentage of operating revenue, each net of fuel surcharge revenue; and net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads). We provide these additional disclosures because management believes these measures provide a more consistent basis for comparing results of operations from period to period. These financial measures in this report have not been determined in accordance with U.S. generally accepted accounting principles (GAAP). Pursuant to Item 10(e) of Regulation S-K, we have included the amounts necessary to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures of operating revenue, operating expenses divided by operating revenue, and fuel and fuel taxes.

Results of Operations

The following table sets forth for the years indicated certain operating statistics regarding our revenue and operations: 

Comparison of Year Ended December 31, 2023 to Year Ended December 31, 2022

The following table sets forth for the years indicated our operating revenue, operating income and operating ratio by segment, along with the change for each component:

Our operating revenue decreased $132.4 million, or 10.5%, to $1.131 billion in 2023 from $1.264 billion in 2022. Our operating revenue, net of fuel surcharges, decreased $81.4 million, or 7.7%, to $972.0 million in 2023 from $1.053 billion in 2022. This decrease in 2023 was due to a $38.9 million decrease in Brokerage revenue, a $24.6 million decrease in Intermodal revenue, net of fuel surcharges, a $15.9 million decrease in Truckload revenue, net of fuel surcharges, and a $2.0 million decrease in Dedicated revenue, net of fuel surcharges. Fuel surcharge revenue decreased to $159.4 million in 2023 from $210.4 million in 2022.

In addition to the factors discussed below, our profitability across each segment in 2023 was impacted by a freight market which has considerably softened from the exceptionally tight conditions during 2022.

Truckload segment revenue decreased $35.0 million, or 7.0%, to $465.5 million in 2023 from $500.5 million in 2022. Truckload segment revenue, net of fuel surcharges, decreased $15.9 million, or 3.9%, to $395.6 million in 2023 from $411.4 million in 2022 primarily due to a decrease in our average revenue per tractor, despite an increase in our average fleet size. The operating ratio increased to 94.7% in 2023 from 88.1% in 2022. Impacting the 2023 operating ratio was a decrease in our average revenue per tractor along with higher company driver compensation, depreciation, maintenance and net fuel costs as a percentage of revenue.

Dedicated segment revenue decreased $20.8 million, or 4.9%, to $408.3 million in 2023 from $429.1 million in 2022. Dedicated segment revenue, net of fuel surcharges, decreased 0.6% primarily due to a decrease in our average revenue per tractor. The operating ratio was 88.2% in each of 2023 and 2022.

Intermodal segment revenue decreased $37.7 million, or 29.0%, to $92.1 million in 2023 from $129.8 million in 2022. Intermodal segment revenue, net of fuel surcharges, decreased 24.5% from 2022 primarily due to decreases in both our number of loads and our revenue per load. The operating ratio in 2023 increased to 100.2% from 91.8% in 2022. Impacting the 2023 operating ratio was a decrease in our revenue per load along with higher net fuel, company driver compensation, depreciation, maintenance, purchased transportation and chassis rental costs as a percentage of revenue.

Brokerage segment revenue decreased $38.9 million, or 19.0%, to $165.6 million in 2023 from $204.6 million in 2022 primarily due to decreases in both our revenue per load and our number of loads. The operating ratio in 2023 of 89.7% was up from 88.9% in 2022. This increase was due to higher costs across most areas of the segment, partially offset by a decrease in the amounts payable to carriers for transportation services which we arranged as a percentage of our Brokerage revenue.

The following table sets forth for the years indicated the dollar and percentage increase or decrease of the items in our consolidated statements of operations, and those items as a percentage of operating revenue:

Salaries, wages and benefits consist of compensation for our employees, including both driver and non-driver employees, employees’ health insurance, 401(k) plan contributions and other fringe benefits. These expenses vary depending upon the size of our Truckload, Dedicated and Intermodal tractor fleets, the ratio of company drivers to independent contractors, our efficiency, our experience with employees’ health insurance claims, changes in health care premiums and other factors. Salaries, wages and benefits expense decreased $11.5 million, or 2.9%, in 2023 from 2022. This decrease resulted primarily from a $9.6 million decrease in bonus compensation expense for our non-driver employees and lower company driver compensation expense of $4.6 million, partially offset by a $4.7 million increase in non-driver compensation expense.

Purchased transportation consists of amounts payable to railroads and carriers for transportation services we arrange in connection with Brokerage and Intermodal operations and to independent contractor providers of revenue equipment. This category will vary depending upon the amount and rates, including fuel surcharges, we pay to third-party railroad and motor carriers, the ratio of company drivers versus independent contractors and the amount of fuel surcharges passed through to independent contractors. Purchased transportation expense decreased $50.5 million in total, or 20.2%, in 2023 from 2022. Amounts payable to carriers for transportation services we arranged in our Brokerage segment decreased $34.1 million to $136.1 million in 2023 from $170.1 million in 2022, primarily due to decreases in both our cost per load and number of loads. Amounts payable to railroads and drayage carriers for transportation services within our Intermodal segment decreased to $47.5 million in 2023 from $65.3 million in 2022, primarily due to decreases in both our number of loads and cost per load. The portion of purchased transportation expense related to independent contractors within our Truckload and Dedicated segments, including fuel surcharges, increased $1.3 million in 2023. We expect our purchased transportation expense to increase as we grow our Intermodal and Brokerage segments.

Fuel and fuel taxes decreased by $38.1 million, or 17.4%, in 2023 from 2022. Net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads) increased $5.2 million, or 16.2%, to $37.1 million in 2023 from $31.9 million in 2022. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads decreased to $16.0 million from $23.8 million in 2022. The United States Department of Energy, or DOE, national average cost of fuel decreased to $4.21 per gallon from $4.99 per gallon in 2022. Despite this price decrease, our net fuel expense increased to 4.6% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, in 2023 from 3.8% in 2022, primarily due to the record heat in the third quarter of 2023. We have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers’ fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in the temperature-control units on our trailers. Auxiliary power units, which we have installed in our company-owned tractors, provide climate control and electrical power for our drivers without idling the tractor engine.

Supplies and maintenance consist of repairs, maintenance, tires, parts, oil and engine fluids, along with load-specific expenses including loading/unloading, tolls, pallets and trailer hostling. Our supplies and maintenance expense increased $11.7 million, or 21.0%, from 2022 primarily due to higher outside repair, loading/unloading and parts costs.

Depreciation relates to owned tractors, trailers, containers, auxiliary power units, communication units, terminal facilities and other assets. The $5.7 million, or 5.1%, increase in depreciation in 2023 was primarily due to an increase in our average tractor fleet size during the year, along with higher prices of new equipment. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of continued higher prices of new equipment, which will result in greater depreciation over the useful life.

Insurance and claims consist of the costs of insurance premiums and accruals we make for claims within our self-insured retention amounts, primarily for personal injury, property damage, physical damage to our equipment, cargo claims and workers’ compensation claims. These expenses will vary primarily based upon the frequency and severity of our accident experience, our self-insured retention levels and the market for insurance. The $5.5 million, or 10.9% increase in insurance and claims in 2023 was primarily due to increases in our self-insured cost of physical damage claims related to our revenue equipment, self-insured workers’ compensation claim costs and insurance premiums, partially offset by a reduction in our self-insured auto liability claim costs. Our significant self-insured retention exposes us to the possibility of significant fluctuations in claims expense between periods which could materially impact our financial results depending on the frequency, severity and timing of claims.

Gain on disposition of revenue equipment was $13.6 million in 2023, up slightly from $13.4 million in 2022 primarily due to an increase in the number of units sold, offset by a decrease in the average gain for our tractor and trailer sales. Future gains or losses on dispositions of revenue equipment will be impacted by the market for used revenue equipment, which is beyond our control.

Our operating income declined 37.1% to $90.1 million in 2023 from $143.3 million in 2022 as a result of the foregoing factors. Our operating expenses as a percentage of operating revenue, or “operating ratio,” was 92.0% in 2023 and 88.7% in 2022. The operating ratio for our Truckload segment was 94.7% in 2023 and 88.1% in 2022, for our Dedicated segment was 88.2% in each of 2023 and 2022, for our Intermodal segment was 100.2% in 2023 and 91.8% in 2022, and for our Brokerage segment was 89.7% in 2023 and 88.9% in 2022. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, was 90.7% in 2023 and 86.4% in 2022.

Other non-operating income increased to $3.8 million from $827,000 in 2022 due to increased interest income earned on our cash and cash equivalents.

Our effective income tax rate increased to 25.1% in 2023 from 23.5% in 2022 primarily due to increases in per diem and other non-deductible expenses.

As a result of the factors described above, net income declined 36.2% to $70.4 million, or $0.86 per diluted share, in 2023 from $110.4 million, or $1.35 per diluted share, in 2022.

Comparison of Year Ended December 31, 2022 to Year Ended December 31, 2021

The following table sets forth for the years indicated our operating revenue, operating income and operating ratio by segment, along with the change for each component:

Our operating revenue increased $290.2 million, or 29.8%, to $1.264 billion in 2022 from $973.6 million in 2021. Our operating revenue, net of fuel surcharges, increased $197.5 million, or 23.1%, to $1.053 billion in 2022 from $855.9 million in 2021. This increase in 2022 was due to a $65.2 million increase in Truckload revenue, net of fuel surcharges, a $60.1 million increase in Dedicated revenue, net of fuel surcharges, a $59.3 million increase in Brokerage revenue, and a $13.0 million increase in Intermodal revenue, net of fuel surcharges. Fuel surcharge revenue increased to $210.4 million in 2022 from $117.7 million in 2021 primarily due to higher fuel costs.

Truckload segment revenue increased $103.8 million, or 26.2%, to $500.5 million in 2022 from $396.7 million in 2021. Truckload segment revenue, net of fuel surcharges, increased $65.2 million, or 18.8%, to $411.4 million in 2022 from $346.3 million in 2021 primarily due to an increase in our average revenue per tractor. The operating ratio increased to 88.1% in 2022 from 87.1% in 2021. Impacting the 2022 operating ratio were higher company driver compensation, driver recruitment and retention and fuel costs, partially offset by an increase in our average revenue per tractor due to increased rates with our customers.

Dedicated segment revenue increased $99.7 million, or 30.2%, to $429.1 million in 2022 from $329.4 million in 2021. Dedicated segment revenue, net of fuel surcharges, increased 21.7% primarily due to an increase in our average revenue per tractor. The operating ratio in 2022 was positively impacted by an increase in our average revenue per tractor due to increased rates with our customers and reduced depreciation expense as a percentage of revenue, partially offset by higher company driver compensation costs.

Intermodal segment revenue increased $27.5 million, or 26.9%, to $129.8 million in 2022 from $102.2 million in 2021. Intermodal segment revenue, net of fuel surcharges, increased 14.8% from 2021 primarily due to an increase in revenue per load. The operating ratio in 2022 was negatively impacted by higher company driver compensation, chassis rental and amounts payable to railroads as a percentage of our revenue, partially offset by increased rates with our customers.

Brokerage segment revenue increased $59.3 million, or 40.8%, to $204.6 million in 2022 from $145.3 million in 2021 primarily due to an increase in the number of loads. The improvement in the operating ratio in 2022 was primarily due to increased rates with our customers.

The following table sets forth for the years indicated the dollar and percentage increase or decrease of the items in our consolidated statements of operations, and those items as a percentage of operating revenue:

Salaries, wages and benefits expense increased $72.3 million, or 22.8%, in 2022 from 2021. This increase resulted primarily from additional company driver compensation expense of $53.8 million, a $7.1 million increase in non-driver compensation expense, a $3.8 million increase in employees’ health insurance expense as a result of higher self-insured medical claims and a $2.5 million increase in bonus compensation expense for our non-driver employees.

Purchased transportation expense increased $56.6 million in total, or 29.3%, in 2022 from 2021. Amounts payable to carriers for transportation services we arranged in our Brokerage segment increased $49.0 million to $170.1 million in 2022 from $121.1 million in 2021, primarily due to an increase in the cost per load within the tight freight market and growth in load volume. Amounts payable to railroads and drayage carriers for transportation services within our Intermodal segment increased $9.5 million to $65.3 million in 2022 from $55.8 million in 2021 due to higher fuel surcharges paid to the railroads. The portion of purchased transportation expense related to independent contractors within our Truckload and Dedicated segments, including fuel surcharges, decreased $1.9 million in 2022.

Fuel and fuel taxes increased by $87.3 million, or 66.5%, in 2022 from 2021. Net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads) increased $5.0 million, or 18.5%, to $31.9 million in 2022 from $26.9 million in 2021. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads increased to $23.8 million from $13.3 million in 2021. The DOE national average cost of fuel increased to $4.99 per gallon from $3.29 per gallon in 2021. Despite this increase, our net fuel expense was 3.8% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, in each of 2022 and 2021. We have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers’ fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in the temperature-control units on our trailers.

Our supplies and maintenance expense increased $10.2 million, or 22.5%, from 2021, primarily due to higher outside repair, parts and tire costs, along with increased loading/unloading and tolls costs.

The $8.5 million, or 20.3%, increase in insurance and claims in 2022 was primarily due to increases in our self-insured auto liability claim costs and in the self-insured cost of physical damage claims related to our revenue equipment.

Gain on disposition of revenue equipment was $13.4 million in 2022, down from $16.3 million in 2021 primarily due to a decrease in the number of units sold, partially offset by an increase in the average gain for our tractor and trailer sales.

The $11.2 million increase in other operating expenses in 2022 was primarily due to increases in costs associated with driver recruitment and retention along with travel and meals expense.

Our operating income improved 28.3% to $143.3 million in 2022 from $111.7 million in 2021 as a result of the foregoing factors. Our operating expenses as a percentage of operating revenue, or “operating ratio,” was 88.7% in 2022 and 88.5% in 2021. The operating ratio for our Truckload segment was 88.1% in 2022 and 87.1% in 2021, for our Dedicated segment was 88.2% in 2022 and 89.0% in 2021, for our Intermodal segment was 91.8% in 2022 and 90.7% in 2021, and for our Brokerage segment was 88.9% in 2022 and 89.8% in 2021. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, improved to 86.4% in 2022 from 87.0% in 2021.

Our effective income tax rate was 23.5% in each of 2022 and 2021.

As a result of the factors described above, net income improved 29.2% to $110.4 million, or $1.35 per diluted share, in 2022 from $85.4 million, or $1.02 per diluted share, in 2021.

Liquidity and Capital Resources 

Our business requires substantial ongoing capital investments, particularly for new tractors and trailers. Our primary sources of liquidity are funds provided by operations and our revolving credit facility. A portion of our tractor fleet is provided by independent contractors who own and operate their own equipment. We have no capital expenditure requirements relating to those drivers who own their tractors or obtain financing through third parties.

The table below reflects our net cash flows provided by operating activities, net cash flows used for investing activities and net cash flows used for financing activities for the years indicated.

In August 2019, our Board of Directors approved and we announced an increase from current availability in our existing share repurchase program providing for the repurchase of up to $34.0 million, or approximately 1.8 million shares, of our common stock, which was increased by our Board of Directors to 2.7 million shares in August 2020 to reflect the three-for-two stock split effected in the form of a stock dividend on August 13, 2020. On May 3, 2022, our Board of Directors approved and we announced an additional increase from current availability in our existing share repurchase program providing for the repurchase of up to $50.0 million, or approximately 3.1 million shares, of our common stock. The share repurchase program allows purchases on the open market or through private transactions in accordance with Rule 10b-18 of the Exchange Act. The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does not have an expiration date.

We repurchased and retired 1.3 million shares of common stock for $25.0 million in the first quarter of 2022, and 963,000 shares of common stock for $16.8 million in the second quarter of 2022. We did not repurchase any shares in 2023, the third or fourth quarters of 2022, or in 2021. As of December 31, 2023, future repurchases of up to $33.2 million, or approximately 2.2 million shares, were available in the share repurchase program.

In 2023, net cash flows provided by operating activities of $164.4 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $163.9 million, to pay cash dividends of $19.5 million and to construct and upgrade regional operating facilities in the amount of $8.6 million, resulting in a $27.4 million decrease in cash and cash equivalents. In 2022, net cash flows provided by operating activities of $219.5 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $120.9 million, to repurchase and retire 2.3 million shares of our common stock for $41.8 million, to pay cash dividends of $19.6 million and to construct and upgrade regional operating facilities in the amount of $11.2 million, resulting in a $23.6 million increase in cash and cash equivalents. In 2021, net cash flows provided by operating activities of $171.2 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $118.3 million, to pay cash dividends of $54.7 million and to construct and upgrade regional operating facilities in the amount of $4.3 million, resulting in a $9.1 million decrease in cash and cash equivalents.

We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $165 million in 2024. This amount includes commitments to purchase $181 million of new revenue equipment in 2024. Additionally, operating lease obligations total $561,000 through 2028. Quarterly cash dividends of $0.06 per share of common stock were paid in each quarter of 2023 which totaled $19.5 million. Quarterly cash dividends of $0.06 per share of common stock were paid in each quarter of 2022 which totaled $19.6 million. We paid cash dividends totaling $54.7 million in 2021 which consisted of a special dividend of $0.50 per share of common stock in October, along with quarterly cash dividends of $0.04 per share of common stock in March, June, October and December. We currently expect to continue to pay quarterly cash dividends in the future. The payment of cash dividends in the future, and the amount of any such dividends, will depend upon our financial condition, results of operations, cash requirements and certain corporate law requirements, as well as other factors deemed relevant by our Board of Directors. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

In August 2022, we entered into a credit agreement that provides for an unsecured committed credit facility with an aggregate principal amount of $30.0 million which matures in August 2027. The credit agreement amends, restates and continues in its entirety our previous credit agreement, as amended. At December 31, 2023, there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $20.7 million and remaining borrowing availability of $9.3 million. At December 31, 2022, there was also no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit of $16.1 million on the facility. This facility bears interest at a variable rate based on the Term SOFR Rate plus applicable margins. The interest rate for the facility that would apply to outstanding principal balances was 8.5% at December 31, 2023.

Our credit agreement effective in August 2022 prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of $150 million. Our previous credit agreement prohibited us from making such payments in excess of 25% of our net income from the prior fiscal year. Waivers allowing stock redemptions and dividends in excess of the 25% limitation in total amounts of up to $80 million in each of 2022 and 2021 were obtained from the lender in March 2022 and August 2021, respectively. The current and previous credit agreements also contain restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at December 31, 2023 and December 31, 2022.

Other than our obligations for revenue equipment and operating lease expenditures, along with our outstanding standby letters of credit to guarantee settlement of self-insurance claims, which are each mentioned above, we did not have any material off-balance sheet arrangements at December 31, 2023.

Seasonality

Our tractor productivity generally decreases during the winter season because inclement weather impedes operations and some shippers reduce their shipments. At the same time, operating expenses generally increase, with harsh weather creating higher accident frequency, increased claims, lower fuel efficiency and more equipment repairs.

Critical Accounting Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue and expenses in our consolidated financial statements and related notes. We base our estimates, assumptions and judgments on historical experience, current trends and other factors believed to be relevant at the time our consolidated financial statements are prepared. However, because future events and their effects cannot be determined with certainty, actual results could differ from our estimates and assumptions, and such differences could be material. We believe that the following area involves critical accounting estimates due to the levels of subjectivity and judgment that are necessary to account for its highly uncertain matters, the susceptibility of such matters to change and the potentially material impact these estimates and assumptions could have to our financial condition and operating performance.

Auto Liability and Workers’ Compensation Claims Reserves. We self-insure for our portion of claims exposure resulting from auto liability and workers’ compensation claims. We are responsible for the first $1.0 million on each auto liability claim and for the first $750,000 on each workers’ compensation claim. Additionally, we have $20.7 million in standby letters of credit to guarantee settlement of claims under agreements with our insurance carriers and regulatory authorities. We maintain insurance coverage for per-incident and total losses in excess of these risk retention levels in amounts we consider adequate based upon historical experience and our ongoing review. However, we could suffer a series of losses within our self-insured retention limits or losses over our policy limits which could negatively affect our financial condition and operating results. Our auto liability and workers’ compensation claims expense and the related claims reserves will vary primarily based upon the frequency and severity of our accident experience. The total auto liability and workers’ compensation claims reserves within the insurance and claims accruals in our consolidated balance sheets were $40.3 million and $39.3 million as of December 31, 2023 and 2022, respectively. The excess of the insurance and claims accruals over these amounts relates to general liability, cargo and property damage claims, along with reserves for physical damage to our equipment and outstanding employees’ health insurance claims.

We reserve for the estimated cost of the uninsured portion of pending auto liability and workers’ compensation claims, including legal costs. These case reserves are periodically evaluated and adjusted based on our continuing evaluation of the nature and severity of each individual claim. Claims development factors are applied to the total amount of the individual claims’ case reserves by year incurred to estimate future claims development based on our historical experience. Our claims development factors phase down each year over nine years for auto liability claims and eleven years for workers’ compensation claims from the year incurred. We also ensure that our total recorded auto liability and workers’ compensation claims reserves are within a range of reasonable amounts determined in an independent actuarial analysis. There were no changes to our methodology used to estimate our ultimate claims losses in 2023 or 2022. Projection of losses is subject to a high level of estimation uncertainty and actual results could differ from these current estimates. Our estimates require judgments concerning the nature and severity of each claim, historical trends, consultation with actuarial experts, settlement patterns, jury awards, litigation trends and legal interpretations, which are difficult to predict.

We are exposed to a variety of market risks, most importantly the effects of the price and availability of diesel fuel. We require substantial amounts of diesel fuel to operate our tractors and power the temperature-control units on our trailers. The price and availability of diesel fuel can vary, and are subject to political, economic and market factors that are beyond our control. Significant increases in diesel fuel costs could materially and adversely affect our results of operations and financial condition. Based upon our fuel consumption in 2023, a 5% increase in the average cost of diesel fuel would have increased our fuel expense by $8.8 million.

We have historically been able to pass through a significant portion of long-term increases in diesel fuel prices and related taxes to customers in the form of fuel surcharges. Fuel surcharge programs are widely accepted among our customers, though they can vary somewhat from customer-to-customer. These fuel surcharges, which adjust weekly with the cost of fuel, enable us to recover a substantial portion of the higher cost of fuel as prices increase. These fuel surcharge provisions are not effective in mitigating the fuel price increases related to non-revenue miles or fuel used while the tractor is idling. In addition, we have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers’ fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in our trailers’ refrigeration units.

While we do not currently have any outstanding hedging instruments to mitigate this market risk, we may enter into derivatives or other financial instruments to hedge a portion of our fuel costs in the future.

Management’s Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended, for Marten Transport, Ltd. and subsidiaries (the “Company”). This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and even when determined to be effective, can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, projection of any evaluation of the effectiveness of internal control over financial reporting to future periods is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.

Management, with the participation of the Company’s Chief Executive Officer and Executive Vice President and Chief Financial Officer, evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. In making this evaluation, management used the criteria established in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2023. Further, the Company’s independent registered public accounting firm, Grant Thornton LLP, has issued a report on the Company’s internal controls over financial reporting on page 32 of this Report.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Auto and workers’ compensation self-insurance reserves

As described further in Note 1 and Note 13 of the consolidated financial statements, the Company self-insures for a portion of their claims exposure resulting from workers’ compensation claims and auto liability claims. The Company maintains insurance coverage for per incident and total losses in excess of their risk retention levels in amounts they consider adequate based upon historical experience and their ongoing review. The Company reserves for the estimated cost of the uninsured portion of pending claims, including legal costs. These reserves are periodically evaluated and adjusted based on the Company’s evaluation of the nature and severity of outstanding individual claims and an estimate of future claims development based on historical development. Insurance and claims expenses, including the related insurance and claims reserves, will vary primarily based upon the frequency and severity of the Company’s accident experience.
