ITEM 1A. RISK FACTORS

When evaluating our company, the following risks should be considered in conjunction with the other information contained in this Annual Report. If we are unable to mitigate and/or are exposed to any of the following risks in the future, then there could be a material, adverse effect on our business, results of operations, or financial condition.

Our risks are grouped into the following risk categories:

Strategic Operational Compliance Financial

*Market Changes *Customers *Internal Controls *Debt

*International Operations *Insurance *Labor Regulation *Investments

*Mergers and Acquisitions *Employees and Contractors *ESG *Taxation

*Systems and Cybersecurity *Dividend Policy

*Public Health

*Climate Change

Strategic Risk

Our business is subject to economic, credit, business, and regulatory factors that are largely beyond our control, any of which could have a materially adverse effect on our results of operations.

The full truckload, LTL, intermodal, and brokerage industries are highly cyclical, and our business is dependent on a number of factors that may have a materially adverse effect on our results of operations, many of which are beyond our control. In the pursuit of our goal of building a nationwide in-house LTL network, there can be no assurance that we will be able to successfully add new markets or terminals, or whether such markets and terminals will be profitable. Expansion of our LTL network could disrupt our existing operations, distract management as they seek to improve operations from the expansion, incur additional costs as we work to make new locations operational, and increase the risks associated with our LTL operations if such expansion is detrimental to our profitability, service levels, or operations.

Economic conditions that decrease shipping demand or increase the supply of available tractors and trailers can exert downward pressure on rates and equipment utilization, thereby decreasing asset productivity. The risks associated with these factors are heightened when the US economy is weakened. During such times, we may experience a reduction in overall freight levels and freight patterns may change as supply chains are redesigned, resulting in an imbalance between our capacity and our customers’ freight demands. Unfavorable market and economic conditions such as weakened freight demand and inflation have had a materially adverse impact on our results of operations in the past, and the occurrence or continuance thereof could have similar impacts in the future.

We cannot predict future economic conditions, fuel price fluctuations, cost increases, revenue equipment resale values, or how consumer confidence, macroeconomic conditions, or production capabilities, could be affected by armed conflicts or terrorist attacks, government efforts to combat terrorism, military action against or from a foreign state or group located in a foreign state, or heightened security requirements. Enhanced security measures in connection with such events could impair our operating efficiency and productivity and result in higher operating costs. In addition, the Trump administration has stated its intention to impose new or increased tariff rates on imported goods from a number of countries, including China, Canada, Mexico, and the EU. Such trade policies and tariff implementations, and any related retaliatory trade policies and tariff implementations by foreign government may result in decreased shipping volumes, increased equipment and fuel costs, and could have an adverse impact on our revenues and results of operations.

We operate in a highly competitive and fragmented industry, and numerous competitive factors could limit growth opportunities and could have a materially adverse effect on our results of operations.

We operate in a highly competitive industry. The following factors could limit our growth opportunities and have a materially adverse effect on our results of operations:

•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 or grow profitability of our business;

24

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

•some of our customers operate their own private trucking fleets and they may decide to transport more of their own freight;

•competition from non-asset-based and other logistics and freight brokerage companies, or LTL providers with a nationwide network, may adversely affect our customer relationships and freight rates;

•advances in technology may require us to increase investments in order to remain competitive, and our customers may not be willing to accept higher freight rates to cover the cost of these investments; and

•our brand names are valuable assets that are subject to the risk of adverse publicity (whether or not justified), which could result in the loss of value attributable to our brand and reduced demand for our services.

Increased prices for new revenue equipment, design changes of new engines, decreased availability of new revenue equipment, future use of autonomous trucks, and the failure of manufacturers to meet their sale or trade-back obligations to us could have a materially adverse effect on our business, financial condition, results of operations, and profitability.

We are subject to risk with respect to higher prices for new equipment for our full truckload and LTL operations. We have experienced an increase in prices for new tractors and trailers in recent periods, and the resale value of the tractors and trailers has not increased to the same extent. Increased regulation has increased the cost of our new tractors and could impair equipment productivity, in some cases, resulting in lower fuel mileage, and increasing our operating expenses. Future use of autonomous and alternative fuel tractors could increase the price of new tractors and decrease the value of used, non-autonomous tractors. We expect equipment prices to continue to rise for the foreseeable future.

Tractor and trailer vendors may reduce their manufacturing output in response to lower demand for their products in economic downturns or shortages of component parts. Lower output from manufacturers could have a materially adverse effect on our ability to purchase or take possession of a quantity of new revenue equipment that is sufficient to sustain our desired growth rate and to maintain a late-model fleet. Tractor and trailer manufacturers have experienced periodic shortages of certain components and supplies, particularly during the COVID-19 pandemic, including semiconductor chips, forcing some manufacturers to curtail or suspend their production, which led to a lower supply of tractors and trailers and higher prices. An inability to obtain an adequate supply of new tractors or trailers could have a material adverse effect on our business, financial condition, and results of operations, particularly our maintenance expense, the length of our trade cycle, and driver retention.

We have certain revenue equipment leases and financing arrangements with balloon payments at the end of the lease term similar to the residual value we are contracted to receive from certain equipment manufacturers upon sale or trade back to the manufacturers. If we do not purchase new equipment that triggers the trade-back obligation, or the equipment manufacturers do not pay the contracted value at the end of the lease term, we could be exposed to losses if and to the extent the balloon payment owed to the lease or finance company exceeds the proceeds from selling the equipment on the open market.

We have trade-in and repurchase commitments that specify, among other things, what our primary equipment vendors will pay us for disposal of a substantial portion of our revenue equipment. The prices we expect to receive under these arrangements may be higher than the prices we would receive in the open market. We may suffer a financial loss upon disposition of our equipment if these vendors refuse or are unable to meet their financial obligations under these agreements.

Declines in demand for our used revenue equipment could result in decreased equipment sales, resale values, and gains on sales of assets.

We are sensitive to the used equipment market and fluctuations in prices and demand for tractors and trailers. The market for used equipment is affected by several factors, including the demand for freight, the supply of new and used equipment, the availability and terms of financing, the presence of buyers for export to foreign countries, and commodity prices for scrap metal. Declines in demand for the used equipment we sell could result in diminished sales volumes or lower used equipment sales prices, either of which could negatively affect our gains on sales of assets. We have seen a softening of the used equipment market recently, which has led to lower gain on sale in recent quarters.

If fuel prices increase significantly or fuel availability becomes scarce, our results of operations could be adversely affected.

Our full truckload and LTL operations are dependent upon diesel fuel, and accordingly, significant increases in diesel fuel costs or decreases in availability of fuel could materially and adversely affect our results of operations and financial condition if we are unable to pass increased costs on to customers through rate increases or fuel surcharges.

The price and availability of diesel fuel are subject to fluctuations due to changes in the level of global oil production, seasonality, weather, global politics, tariffs, and other market factors. Fuel is subject to regional pricing differences and often costs more on the West Coast and in the Northeast, where we have significant operations. While we use a fuel surcharge program to recapture a portion of the increases in fuel prices it does not protect us against the full effect of increases in fuel prices. Because our fuel surcharge recovery lags behind changes in fuel prices our fuel surcharge recovery may not capture the increased costs we pay for fuel, especially when prices are rising. Our results of operations would be negatively affected and more volatile to the extent we cannot recover higher fuel costs or fail to improve our fuel price protection through our fuel surcharge program. Any widespread or long-term shortage or rationing of diesel fuel could materially and adversely affect our results of operations.

Global conflicts could adversely impact our business and financial results.

Although we do not have any direct operations in Russia, Belarus, Ukraine, the Middle East, China, or Taiwan, we may be affected by the broader consequences of such conflicts or their expansion to other areas or countries or similar conflicts elsewhere, such as increased inflation, supply chain issues, including shortages of new revenue equipment, access to parts for our revenue equipment, embargoes, tariffs, geopolitical shift, access to or increased prices for diesel fuel, higher energy prices, potential retaliatory action by foreign governments, including cyber-attacks, and the extent of an armed conflict’s effect on the global economy. The magnitude of these risks cannot be predicted, including the extent to which the conflict may heighten other risks disclosed herein. Ultimately, these or other factors could materially and adversely affect our results of operations.

We are subject to certain risks arising from doing business in Mexico.

We have operations in Mexico, which subjects us to general international business risks, including:

•foreign currency fluctuation;

•changes in Mexico's economic strength;

•disruptions related to port of entry restrictions;

•difficulties in enforcing contractual obligations and intellectual property rights;

•burdens of complying with a wide variety of international and US export, import, business procurement, transparency, and corruption laws, including the US Foreign Corrupt Practices Act;

•changes in trade agreements, US-Mexico trade relations, or the imposition of tariffs on imports from Mexico and related retaliatory tariffs that may be imposed by the Mexican government;

•theft or vandalism of our revenue equipment; and

•social, political, and economic instability.

We may not make acquisitions in the future, or if we do, we may not be successful in our acquisition strategy.

Historically, acquisitions have been a part of our growth strategy. There is no assurance that we will be successful in identifying, negotiating, or consummating any future acquisitions. If we do not make any future acquisitions, our growth rate could be materially and adversely affected. Any future acquisitions we undertake could involve issuing dilutive equity securities or incurring indebtedness, the terms of which may be less favorable to us than anticipated. In addition, acquisitions (including our recent acquisition of U.S. Xpress and DHE) involve numerous risks, any of which could have a materially adverse effect on our business and results of operations, including:

•the acquired company may not achieve anticipated revenue, earnings, or cash flow;

•we may assume liabilities beyond our estimates or what was disclosed to us;

•we may be unable to successfully assimilate or integrate the acquired company's operations or assets into our business and realize the anticipated economic, operational, and other benefits in a timely manner, which could result in substantial costs and delays or other operational, technical, or financial problems;

26

•transaction costs and acquisition-related integration costs could adversely affect our results of operations in the period in which such costs are recorded;

•the potential for deficiencies in internal controls at the acquired business, as well as implementing our own management information systems, operating systems and internal controls for the acquired operations;

•the timing and impact of purchase accounting adjustments;

•diverting our management's attention from other business concerns;

•risks of entering into new markets or business offerings in which we have had no or only limited prior experience; and

•the potential loss of customers, key employees, or driving associates of the acquired company.

Operational Risk

We may not grow substantially in the future and we may not be successful in sustaining or improving our profitability.

There is no assurance that in the future, our business will grow substantially or without volatility, nor can we assure you that we will be able to effectively adapt our management, administrative, and operational systems to respond to any future growth. Our operating margins may be adversely affected by future changes in and expansion of our business or by changes in economic conditions and we may not be able to sustain or improve our profitability in the future.

Furthermore, the continued progression and development of new business offerings are subject to risks, including, but not limited to:

•initial unfamiliarity with pricing, service, operational, and liability issues;

•the potential need for additional capital, including for terminals and equipment;

•customer relationships may be difficult to obtain or retain, or we may have to reduce rates to gain and develop customer relationships;

•specialized equipment and information and management systems technology may not be adequately utilized;

•insurance and claims may exceed our past experience or estimations; and

•we may be unable to recruit and retain qualified personnel and management with requisite experience or knowledge of developing service offerings.

We derive a significant portion of our revenues 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 operating revenue is generated from a number of major customers, the loss of one or more of which could have a materially adverse effect on our business. Refer to Part I, Item 1, "Business" for information regarding our customer concentrations. Aside from our dedicated operations, we generally do not have long-term contractual relationships, rate agreements, or minimum volume guarantees with our customers. There is no assurance any of our customers will continue to utilize our services, renew our existing contracts, continue at the same volume levels, or not seek to modify terms of existing contracts, including rates. A reduction in or termination of our services by one or more of our major customers could have a materially adverse effect on our business, financial condition, and results of operations.

Retail and discount retail customers account for a substantial portion of our freight. Accordingly, our results may be more susceptible to trends in unemployment and retail sales than carriers that do not have this concentration.

In addition, our customers' financial difficulties could negatively impact our results of operations and financial condition, especially if these customers were to delay or default on payments to us. For our multi-year and dedicated contracts, the rates we charge may not remain advantageous. Further, despite the existence of contractual arrangements, certain of our customers may nonetheless engage in competitive bidding processes that could negatively impact our contractual relationship.

We depend on third-party capacity providers, and service instability from these transportation providers could increase our operating costs and reduce our ability to offer intermodal and brokerage services, which could adversely affect our revenue, results of operations, and customer relationships.

Our intermodal operations use railroads and some third-party drayage carriers to transport freight for our customers, and intermodal dependence on railroads could increase if we expand our intermodal services. In certain markets, rail service is limited to a few railroads or even a single railroad. Intermodal providers have experienced poor service from providers of rail-based services in the past. Our ability to provide intermodal services in certain traffic lanes would be reduced or eliminated if the railroads' services became unstable. Railroads could reduce their services in the future for various reasons, which may include work stoppages, insufficient network capacity, adverse weather conditions, accidents, or other factors, which could increase the cost of the rail-based services we provide, could create cargo claims, and could reduce the reliability, timeliness, efficiency, and overall attractiveness of our rail-based intermodal services.

Our intermodal operations have been negatively impacted by labor difficulties in recent periods. Although labor challenges in the rail industry have softened, the future threat or occurrence of a work stoppage, strike, or other labor disruption among rail employees could significantly reduce or even halt operating capacity of our intermodal operations, which could have a materially adverse effect on our business, financial condition, and results of operations. Furthermore, price increases could result in higher costs to us, which we may be unable to pass on to our customers and could result in the reduction or elimination of our ability to offer intermodal services. In addition, we may not be able to negotiate additional contracts with railroads to expand our capacity, add additional routes, obtain multiple providers, or obtain railroad services at current cost levels, any of which could limit our ability to provide this service.

Our logistics operations are dependent upon the services of third-party capacity providers, including other truckload and LTL capacity providers. These third-party providers may seek other freight opportunities and may require increased compensation in times of improved freight demand or tight full truckload and LTL capacity. Most of our third-party capacity provider transportation services contracts are cancelable on 30 days' notice or less. If we are unable to secure the services of these third parties, or if we become subject to increases in the prices we must pay to secure such services, and we are not able to obtain corresponding customer rate increases, our business, financial condition, and results of operations may be materially adversely affected.

Insurance and claims expenses could significantly reduce our earnings.

Our future insurance and claims expense might exceed historical levels, which could reduce our earnings. We self-insure, or insure through our captive insurance companies, a significant portion of our claims exposure. For a detailed discussion of our self-insurance programs, including self-insurance retention limits, please refer to Note 10 to the consolidated financial statements, included in Part II, Item 8 of this Annual Report. Higher self-insured retention levels may increase the impact of auto liability occurrences on our results of operations. We reserve for anticipated losses and expenses and periodically evaluate and adjust our claims reserves to reflect our experience. Estimating the number and severity of claims, as well as related judgment or settlement amounts, is inherently difficult, and claims may ultimately prove to be more severe than our estimates. This, along with legal expenses, incurred but not reported claims, and other uncertainties can cause unfavorable differences between actual self-insurance costs and our reserve estimates. Accordingly, ultimate results may differ materially from our estimates, which could result in losses over our reserved amounts and could materially adversely affect our financial condition and results of operations.

Although we believe our aggregate insurance limits should be sufficient to cover reasonably expected claims, it is possible that the amount of one or more claims could exceed our aggregate coverage limits. If any claim were to exceed our coverage, we would bear the excess, in addition to our self-insured amounts. Furthermore, insurance carriers have raised premiums for many businesses, including transportation companies.

In addition, rising healthcare costs could negatively impact financial results or force us to make changes to existing benefit programs, which could negatively impact our ability to attract and retain employees.

Insuring risk through our captive insurance companies could adversely impact our operations.

We insure certain affiliated risks through our captive insurance company, Mohave, and through our risk retention group, Red Rock. Additionally, Mohave provides reinsurance to third-party insurance companies who provide insurance coverage for independent contractors, as well as affiliated carriers through the first quarter of 2024. Based on results of operations of this business, including the continued unfavorable development of insurance reserves, the Company ceased all third-party insurance operations and canceled any remaining policies as of March 31, 2024.

Red Rock insures a share of our automobile liability risk. The insurance and reinsurance markets are subject to market pressures. Our captive insurance companies' access to the reinsurance markets may be restricted or involve the retention of additional risk, which could expose us to volatility in claims expenses.

Our captive insurance companies are regulated by state authorities. State regulations generally provide protection to policy holders, rather than stockholders. These regulations may increase our costs of regulatory compliance, limit our ability to change premiums, restrict our ability to access cash held in our captive insurance companies, and otherwise impede our ability to take actions we deem advisable.

In the future, we may continue to insure our automobile liability risk through our captive insurance subsidiaries, which will cause increases in the required amount of our restricted cash or other collateral, such as letters of credit. Significant increases in the amount of collateral required by third-party insurance carriers and regulators would reduce our liquidity.

If we are unable to recruit, develop, and retain our key employees, our business, financial condition, and results of operations could be adversely affected.

We are highly dependent upon the services of certain key employees and we believe their valuable knowledge about the transportation industry and relationships with our key customers and vendors would be difficult to replicate. We currently do not have employment agreements with our key employees, and the loss of any of their services or inadequate succession planning could negatively impact our operations and future profitability.

Difficulties attracting and retaining qualified driving associates or increases in driving associate compensation could have a materially adverse effect on our profitability and the ability to maintain or grow our fleet.

Difficulty in attracting and retaining sufficient numbers of qualified driving associates, independent contractors, and third-party capacity providers could have a materially adverse effect on our growth and profitability. The truckload and LTL transportation industries are subject to a shortage of qualified driving associates. Such shortage is exacerbated during periods of economic expansion, in which there may be alternative employment opportunities, or during periods of economic downturns, in which unemployment benefits might be extended and financing is limited for independent contractors who seek to purchase equipment or for students who seek financial aid for driving school. Furthermore, capacity at driving schools may be limited by future outbreaks of contagious diseases and any governmental imposed lockdown or other attempts to reduce the spread of such an outbreak may reduce the pool of potential drivers available to us. Regulatory requirements could further reduce the number of eligible driving associates. We believe our employee screening process, which includes background checks and hair follicle drug testing, is more rigorous than generally employed in our industry and has decreased the pool of qualified applicants available to us.Our inability to engage a sufficient number of driving associates and independent contractors may negatively affect our operations.

In addition, we suffer from a high turnover rate of driving associates and independent contractors. This high turnover rate requires us to spend significant resources on recruiting and retention.

Further, our driving associate compensation and independent contractor expenses are subject to market conditions and we may find it necessary to increase driving associate and independent contractor contracted rates in future periods.

Our leasing arrangements with independent contractors expose us to risks that we do not face with our company driving associates.

Our financing subsidiaries offer financing to some of the independent contractors we contract with to purchase or lease tractors from us. If these independent contractors default or experience a lease termination in conjunction with these agreements and we cannot replace them, we may incur losses on amounts owed to us. Also, if liquidity constraints or other restrictions prevent us from providing financing to the independent contractors we contract with in the future, then we could experience a shortage of independent contractors.

Our lease contracts with independent contractors are governed by federal leasing regulations, which impose specific requirements on us and the independent contractors. In the past, we have been the subject of lawsuits, alleging violations of lease agreements or failure to follow the contractual terms, some of which resulted in adverse decisions against the Company. We could be subjected to similar lawsuits and decisions in the future, which if determined adversely to us, could have an adverse effect on our financial condition.

"Other Regulation" in Part I, Item 1 of this Annual Report, discusses how we could be affected by changes in law or regulations regarding our leasing arrangements with independent contractors.

We have operations and business lines in ancillary areas that may increase risk or impair our financial position.

We have from time to time expanded our business lines into ancillary areas, such as support services provided to our customers and third-party carriers, including insurance coverage, equipment maintenance, equipment leasing, warehousing, trailer parts manufacturing, and warranty services. We may incur significant costs in the development and refinement of these business lines, some of which may be outside of our core competency. In addition, the development and expansion of these areas may result in us incurring unanticipated costs to effectively support the new business lines, the potential for disruption to our core business, the distraction of management, the inability to effectively compete with competitors in the areas of our new lines of business, and the potential that we may need to discontinue operations or business lines and incur significant related costs. We cannot guarantee that these businesses or strategies will be successful and any of these businesses or strategies may not achieve the anticipated financial results and could have an adverse effect on volatility, our business, financial condition and operating results. We may decide to divest of business lines, which may involve significant challenges and risks, costs, and disruptions, and may result in ongoing financial or legal involvement in the divested business through indemnification, retained liabilities, or other financial arrangements, which could adversely affect our business, results of operations, and financial condition.

We are dependent on management information and communications systems and other information technology assets (including the data contained therein), and a significant systems disruption or failure in the foregoing, including those caused by cybersecurity breaches, whether internally or with third parties, could adversely affect our business.

Our business depends on the efficient, stable, and uninterrupted operation of our management information and communications systems and other information technology assets (including the data contained therein). Our management information and communication systems are used in various aspects of our business, including accepting and planning loads, dispatching equipment and drivers, billing and collecting for our services, and producing financial statements. If any of our critical information or communications systems fail or become unavailable, it could temporarily affect the efficiency and effectiveness of our operations. Our operations and those of our providers are vulnerable to interruption by natural disasters, such as fires, storms, and floods, which may increase in frequency and severity due to climate change. We and our service providers are also vulnerable to interruption by power loss, telecommunications failure, cyber-attacks, computer viruses, denial-of-service attacks on websites, terrorist attacks, internet failures, and other events beyond our control. More sophisticated and frequent cyber-attacks in recent years have increased security risks associated with information technology systems. The expansion of remote and flexible work arrangements, including those available to our employees, has introduced additional cybersecurity risks, including heightened exposure to phishing and social engineering attacks, potential unauthorized access to sensitive information due to remote access vulnerabilities, and increased compliance considerations. The use of personal devices and videoconferencing applications in remote work environments may further contribute to these risks, potentially increasing the exposure to data breaches or unauthorized disclosure of sensitive information. Our business and operations could be adversely affected in the event of a system failure, disruption, or security breach that causes a delay, interruption, or impairment of our services and operations. Although we carry insurance to help protect us from losses due to an interruption of our systems, there is no

30

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

guarantee such an interruption will fall within the coverage limits of our insurance. Any such failure, inability to upgrade or update, disruption, or security breach (including cyberattacks) related to our systems and technological assets may also impact third-parties upon which we rely in our business, and could hinder our services or such third-parties, which could have a materially adverse effect on our business.

We receive and transmit confidential data in the normal course of business. Despite our implementation of safeguards, our information and communication systems are vulnerable to disruption, unauthorized access and viewing, misappropriation, altering, or deleting of information. A security breach could damage our business operations and reputation and could cause us to incur costs associated with repairing our systems, increased security, customer notifications, lost operating revenue, litigation, regulatory action, and reputational damage. Further, data privacy laws may result in increased liability and compliance and monitoring costs, which could have a material adverse effect on our financial performance and business operations.

In addition, the adoption of artificial intelligence ("AI") and other emerging technologies may become significant to operating results in the future, including in areas such as brokerage, pickup and delivery appointments, and other areas where automation is possible. While AI and other technologies may offer substantial benefits, they may also introduce additional risk, including those relating to errors or inaccuracies in work product developed through the use of AI and privacy, intellectual property, and legal and regulatory risks. If we are unable to successfully implement and utilize such emerging technologies as effectively and as quickly as competitors, our results of operation may be negatively affected.

The impact of climate change, weather, and other catastrophic events and seasonality could have a materially adverse effect on our infrastructure, results of operations and profitability or make our results of operations and profitability more volatile.

The potential physical effects of climate change, such as increased frequency and severity of storms, floods, fires, fog, mist, freezing conditions, sea-level rise and other climate-related events, could cause loss or damage to our equipment or properties, deteriorate or destroy the infrastructure upon which we rely, increase the likelihood of accidents, disrupt fuel supplies, and/or increase our claim liabilities and our cost or ability to obtain insurance coverage, any of which could impair our operations and financial position. Operational impacts, such as the delay or difficult in delivering freight, could result in loss of revenue, decrease the demand for our services, and harm our reputation. In addition, certain warehouses and loading docks that we frequently utilize and certain of our terminals are in locations susceptible to the impacts of storm-related flooding and sea-level rise, which could result in additional costs and loss of revenue. We could incur significant costs to improve the climate resiliency of our equipment and properties and otherwise prepare for, respond to, and mitigate such physical effects of climate change. We are not able to accurately predict the materiality of any potential losses or costs associated with the physical effects of climate change.

"Seasonality" in Part I, Item 1 of this Annual Report, discusses in detail how seasonality could impact our operations.

The effects of a widespread outbreak of an illness or disease, or any other public health crisis, as well as regulatory measures implemented in response to such events, could negatively impact the health and safety of our workforce and/or adversely impact our business, results of operations, financial condition, and cash flows.

We face a wide variety of risks related to public health crises, epidemics, pandemics or similar events, such as COVID-19. If a new health epidemic or outbreak were to occur, we could experience broad and varied impacts similar to the impact of COVID-19, including adverse impacts to our workforce, our operations, and financial impacts, such as increased costs, tightening of credit markets, market volatility, equipment shortages, and a weakened freight environment. If any of these were to occur, our operations, financial condition, liquidity, results of operations, and cash flows could be adversely impacted.

Compliance Risk

We operate in a highly regulated industry, and changes in existing regulations or violations of existing or future regulations could have a materially adverse effect on our operations and profitability.

We, our drivers, and our equipment are regulated by various federal and state agencies in the states, provinces, and countries in which we operate. Future laws and regulations or changes to existing laws and regulations may be more stringent, require changes in our operating practices, influence the demand for transportation services, or require us to incur significant additional costs, which could materially adversely affect our business, financial condition, and results of operations.

"Industry Regulation" and "Other Regulation" in Part I, Item 1 of this Annual Report, discusses in detail regulations related to our business that could materially impact our business, financial condition, and operations.

Receipt of an unfavorable DOT safety rating or an unfavorable ranking under the CSA program could have a material adverse effect on our profitability and operations.

If we, or one of our subsidiaries, received a conditional or unsatisfactory DOT safety rating or an unfavorable ranking under the CSA program, it could lead to increased risk of liability, increased insurance, maintenance and equipment costs, and potential loss of customers, which could materially adversely affect our business, financial condition, and results of operations.

"Industry Regulation" in Part I, Item 1 of this Annual Report, provides discussion of the DOT safety rating system and the CSA program.

Ineffective internal controls could have a negative impact on our business, results of operations, and our reputation.

Our internal controls over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, failure or interruption of information technology systems, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, including with the implementation of our internal controls in acquired companies, our business and operating results could be harmed and we could fail to meet our financial reporting obligations, which also could have a negative impact on our reputation.

Compliance with various environmental laws and regulations to which our operations are subject may increase our costs of operations, and non-compliance with such laws and regulations could result in substantial fines or penalties.

We are subject to various environmental laws and regulations. We have instituted programs to monitor and control environmental risks and promote compliance with applicable environmental laws and regulations; however, in the event of any of the following, we could be subject to clean-up costs and liabilities, including substantial fines or penalties or civil and criminal liability, any of which could have a materially adverse effect on our business and results of operations:

•we are involved in a spill or other accident involving hazardous substances;

•there are releases of hazardous substances we transport;

•soil or groundwater contamination is found at our facilities or results from our operations; and

•we are found to be in violation of or fail to comply with applicable environmental laws or regulations.

Certain of our terminals are located on or near environmental Superfund sites designated by the EPA and/or state environmental authorities. We have not been identified as a potentially responsible party with regard to any such site. Nevertheless, we could be deemed responsible for clean-up costs.

In addition, tractors and trailers used in our full truckload and LTL operations are affected by laws and regulations related to air emissions and fuel efficiency. Governmental agencies continue to enact more stringent laws and regulations to reduce engine emissions. These laws and regulations are applicable to engines used in our revenue equipment. We have incurred and continue to incur costs related to the implementation of these more rigorous laws and regulations. Additionally, in certain locations governments have banned or may in the future ban internal combustion engines for some types of vehicles. To the extent these bans affect our revenue equipment, we may be

32

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

forced to incur substantial expense to retrofit existing engines or make capital expenditures to update our fleet. As a result, our business, results of operations, and financial condition could be negatively affected.

As the environmental laws and regulations to which we are subject become more stringent, and may become further restrictive given concerns over climate change, we may experience increased costs related to compliance, and if such laws and regulations take effect faster than we anticipate or are prepared for, we may experience difficulty complying. In addition, certain environmental laws and regulations may require us to disclose certain metrics or other data related to our operations that have historically been confidential, or impose additional environmental monitoring or reporting requirements. Failure to comply with these laws and regulations may result in fines or penalties, a decrease in productivity, and other constraints that could impair our financial and operational position and have a negative impact on our stock price and reputation. "Environmental Regulation" in Part I, Item 1 of this Annual Report, provides a discussion of the environmental laws and regulations applicable to our business and operations.

Developments in labor and employment law and any unionizing efforts by employees could have a materially adverse effect on our results of operations.

Although our only collective bargaining agreement exists at our Mexican subsidiary, we always face the risk that our employees will try to unionize. If we entered into a collective bargaining agreement with our domestic employees, it could have a material adverse effect on our business, customer retention, financial condition, results of operations, and liquidity, and could cause significant disruption of, or inefficiencies in, our operations, because:

•restrictive work rules could hamper our ability to improve or sustain operating efficiency or could impair our service reputation and limit our ability to provide certain services;

•a strike or work stoppage could negatively impact our profitability and could damage customer and employee relationships;

•shippers may limit their use of unionized companies because of the threat of strikes and other work stoppages;

•unionization of any of our operations could lead to pressure on our LTL and full truckload employees to unionize;

•collective agreements could result in material increases in wages and benefits; and

•an election and bargaining process could divert management’s time and attention from our overall objectives and impose significant expenses.

If the independent contractors we contract with were ever re-classified as employees, the magnitude of this risk would increase. "Industry Regulation" in Part I, Item 1 of this Annual Report, provides discussion of labor and employment laws applicable to our business and operations.

If our independent contractors are deemed by regulators or the judicial process to be employees, our business, financial condition, and results of operations could be adversely affected.

Tax and other regulatory authorities, as well as independent contractors themselves, have increasingly asserted that independent contractors in the trucking industry are employees rather than independent contractors. Carriers such as us that operate or have operated lease-purchase programs have been more susceptible to lawsuits seeking to reclassify independent contractors that have engaged in such programs. We have been subject to litigation relating to such matters in the past and continue to be at risk moving forward. If the independent contractors we engage were determined to be our employees, we would incur additional exposure under federal and state tax, workers' compensation, unemployment benefits, labor, employment, insurance, discrimination, and tort laws, including for prior periods, as well as potential liability for employee benefits and tax withholdings. Furthermore, if independent contractors were deemed employees, then certain of our third-party revenue sources, including shop and insurance margins, would be eliminated. "Industry Regulation" in Part I, Item 1 of this Annual Report, provides discussion of legislation regarding independent contractors.

Litigation may adversely affect our business, financial condition, and results of operations.

The nature of our business exposes us to the potential for various claims and litigation, including class-action litigation and other legal proceedings related to personal injury, labor and employment, property damage, cargo claims, safety and contract compliance, environmental liability, and other matters, and we have been subject to litigation regarding these matters in the past. The number and severity of litigation claims may be worsened by various factors, including, among others, weather and distracted driving by both truck drivers and other motorists.

These legal proceedings have resulted, and may result in the future, in the payment of substantial settlements or damages and increases in our insurance costs.

Recently, trucking companies, including us, have been subject to lawsuits, including class action lawsuits, alleging violations of various federal and state wage and hour laws regarding, among other things, employee meal breaks, rest periods, overtime eligibility, and failure to pay for all hours worked. 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 and regulatory actions, 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. We establish reserves based on our assessment of known legal matters and contingencies. New legal claims, or subsequent developments related to known claims, may affect our assessment and estimates of our recorded legal reserves and may require us to make payments in excess of our reserves. The cost to defend litigation may also be significant. Because of the potential expenses and uncertainties associated with litigation, we may from time to time settle disputes, even where we believe we have a meritorious position. Further, 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, involve significant aggregate use of our self-insured retention amounts, or cause increases in future premiums, the resulting expenses could have a materially adverse effect on our business, results of operations, financial condition, or cash flows, and our involvement in legal proceedings could negatively impact our business reputation and our relationship with our customers, suppliers, employees, and stockholders.

Changes to trade regulation, quotas, duties or tariffs, caused by the changing US and geopolitical environments or otherwise, may increase our costs and adversely affect our business.

Recently, the Trump administration has stated its intention to impose new or increased tariff rates on imported goods from a number of countries, including China, Canada, Mexico, and the E.U. The imposition of additional tariffs or quotas or changes to certain trade agreements, or retaliatory trade policies could, among other things, increase the costs of the materials used by our suppliers to produce new revenue equipment, limit the availability of new revenue equipment, or increase the price of fuel. Such cost increases for our revenue equipment suppliers would likely be passed on to us, and to the extent fuel prices increase, we may not be able to fully recover such increases through rate increases or our fuel surcharge program, either of which could have an adverse effect on our business.

Increasing attention on environmental, social, and governance (ESG) matters may have a negative impact on our business, impose additional costs on us, and expose us to additional risks.

Our implementation reporting on ESG matters present numerous operational, financial, legal, reputational and other risks, many of which are outside of our control, and all of which could have a material negative impact on our business. Companies have recently faced attention from stakeholders relating to ESG matters, including environmental stewardship, social responsibility, and diversity and inclusion. Failure to satisfy our stakeholders with regard to ESG matters could negatively impact our reputation, our ability to attract or retain employees, and our attractiveness as an investment and business partner. Organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings may lead to negative investor sentiment toward the Company, which could have a negative impact on our stock price. Further, the Trump administration's initiatives surrounding ESG matters may be inconsistent with stakeholder positions on ESG matters, and we may experience conflicts between actual or proposed governmental regulations and stakeholder expectations, which could negatively impact investor sentiment or expose us to government investigation or enforcement actions.

Financial Risk

We have significant ongoing capital requirements that could affect our profitability if our capital investments do not match customer demand, we are unable to generate sufficient cash from operations, or we are unable to obtain financing on favorable terms.

Our full truckload and LTL operations are capital intensive, and our policy of operating newer equipment requires us to expend significant amounts on capital annually. If anticipated demand differs materially from actual usage, our capital intensive full truckload and LTL operations may have too many or too few assets. Continued growth of our LTL network has increased and will continue to increase our capital requirements for real estate associated with LTL operations. During periods of decreased customer demand, our asset utilization may suffer, and we may be forced to sell equipment on the open market or turn in equipment under certain equipment leases in order to right-size our fleet. This could cause us to incur losses on such sales or require payments in connection with such turn-ins, particularly during times of a softer used equipment market, either of which could have a materially adverse effect on our profitability.

In the event that we are unable to generate sufficient cash from operations, maintain compliance with financial and other covenants in our financing agreements, or obtain equity capital or financing on favorable terms in the future, we may have to limit our fleet size, enter into less favorable financing, or operate our revenue equipment for longer periods, any of which could have a materially adverse effect on our operations and profitability.

If credit markets weaken, it may be difficult for us to access our current sources of credit and may be difficult for our lenders to find the capital to fund us. We may need to incur additional debt, or issue debt or equity securities in the future, to refinance existing debt, fund working capital requirements, make investments, or support other business activities. Declines in consumer confidence, decreases in domestic spending, economic contractions, rating agency actions, and other trends in the credit market may impair our future ability to secure financing on satisfactory terms, or at all.

In the future, we may need to obtain additional financing that may not be available or, if it is available, may result in a reduction in the percentage ownership of our then-existing stockholders.

We may need to raise additional funds in order to:

•finance unanticipated working capital requirements, capital investments, or refinance existing indebtedness;

•develop or enhance our technological infrastructure and our existing products and services;

•fund strategic relationships;

•respond to competitive pressures; and

•acquire complementary businesses, technologies, products, or services.

If the economy and/or the credit markets weaken, or we are unable to enter into finance or operating leases to acquire revenue equipment on terms favorable to us, our business, financial results, and results of operations could be materially adversely affected, especially if consumer confidence declines and domestic spending decreases. If adequate funds are not available or are not available on acceptable terms, our ability to fund our strategic initiatives, take advantage of unanticipated opportunities, develop or enhance technology or services, or otherwise respond to competitive pressures could be significantly limited. If we raise additional funds by issuing equity or convertible debt securities, the percentage ownership of our then-existing stockholders may be reduced, and holders of these securities may have rights, preferences, or privileges senior to those of our then-existing stockholders. Volatility to equity markets could also impair our financial position in general terms and our ability to effectively capitalize on potential merger and acquisition opportunities.

In the event of an economic downturn or disruption in the credit markets, our indebtedness could place us at a competitive disadvantage in terms of our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, and prevent us from meeting our debt obligations compared to our competitors that are less leveraged.

This could have negative consequences that include:

•increased vulnerability to adverse economic, industry, or competitive developments;

•cash flows from operations that are committed to payment of principal and interest, thereby reducing our ability to use cash for our operations, capital expenditures, and future business opportunities;

35

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

•increased interest rates that would affect our variable rate debt or our ability to utilize appropriate leverage in general;

•potential noncompliance with financial covenants, borrowing conditions, and other debt obligations (where applicable);

•lack of financing for working capital, capital expenditures, product development, debt service requirements, and general corporate or other purposes;

•limits on our flexibility to plan for, or react to, changes in our business, market conditions, or in the economy; and

•undertaking cost-saving measures that adversely impact our ability to grow and our long-term financial position.

Our debt agreements contain restrictions that limit our flexibility in operating our business.

As detailed in Note 13 to the consolidated financial statements, included in Part II, Item 8 of this Annual Report, we must comply with various affirmative, negative, and financial covenants. A breach of any of these covenants could result in default or (when applicable) cross-default. Upon default under our primary credit facility, the lenders could elect to declare all outstanding amounts to be immediately due and payable, as well as terminate all commitments to extend further credit. Such actions by those lenders could cause cross-defaults with our other debt agreements. If we were unable to repay those amounts, the lenders could use any collateral granted to satisfy all or part of the debt owed to them. If the lenders accelerated our debt repayments, we might not have sufficient assets to repay all amounts borrowed.

In addition, we have other financing that includes certain affirmative and negative covenants and cross-default provisions. Failure to comply with these covenants and provisions may jeopardize our ability to continue to sell receivables under the facility and could negatively impact our liquidity.

Our debt agreements contain variable rate debt that could affect our financial results should interest rates rise.

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

We could determine that our goodwill and other indefinite-lived intangibles are impaired, thus recognizing a related impairment loss.

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

If our investments in entities are not successful or decrease in market value, we may be required to write off or lose the value of a portion or all of our investments, which could have a materially adverse effect on our results of operations.

Through one of our wholly-owned subsidiaries, we have directly or indirectly invested in certain entities that make privately negotiated equity investments. In the past, the Company has recorded impairment charges to reflect the other-than-temporary decreases in the fair value of its portfolio. If the financial position of any such entity declines, we could be required to write down all or part of our investment in that entity, which could have a materially adverse effect on our results of operations.

Changes in taxation could lead to an increase of our tax exposure and could affect the Company’s financial results.

Our effective tax rate may be adversely impacted by changes in tax laws in jurisdictions where we operate. President Trump has indicated a desire to amend the federal tax laws. Until any changes are passed into law we will not know if such changes, if any, will have a materially adverse effect on our financial results and financial position. At December 31, 2024, the Company has a deferred tax liability of $919.8 million. The amount of deferred tax liability is determined by using the enacted tax rates in effect for the year in which differences between the financial statement and tax basis of assets and liabilities are expected to reverse. Our net current tax liability has been determined based on the currently enacted rate of 21%. If the current rate were to change due to legislation, it would have an immediate revaluation of our deferred tax assets and liabilities in the year of enactment.

ITEM 1C. CYBERSECURITY

Cybersecurity Risk Management and Strategy

Risk Management Strategy

While no organization can eliminate cybersecurity risk entirely, we devote significant resources to our cybersecurity strategy that we believe is reasonably designed to mitigate our cybersecurity and information technology risk. These efforts are designed to protect against, and mitigate the effects of, among other things, cybersecurity incidents where unauthorized parties attempt to access confidential, sensitive, or personal information; potentially hold such information for ransom; destroy data; disrupt or delay our operations or systems; or otherwise cause harm to the Company, our customers, employees, vendors, or other key stakeholders.

Process —We use a multi-layered defensive cybersecurity strategy based on best practices to identify risks, protect technology assets, detect anomalies, respond to, and recover from cybersecurity incidents. Our processes to identify, assess, and manage material risks from cybersecurity threats includes the following:

•Identify - We identify risks from cybersecurity threats by first developing and maintaining an understanding of assets and systems essential to our operations and reputation, as well as assets and systems that could provide value to threat actors. Any attempt by a threat actor is considered a potential risk if a threat actor can use it to reduce the value of an asset, reduce our ability to utilize or otherwise access the value of an asset, or surreptitiously gain or increase their access to an asset or system which would result in decreased information security or a disruption in our operations.

•Assess - We assess risks from cybersecurity threats by evaluating exposure of our assets to identified cyber risks, as well as potential impacts to our operations or reputation from our inability to access or utilize an asset or system, or a threat actor’s ability to gain access to an asset or system. We further evaluate the potential materiality of these risks based on the potential impact to our operations or reputation.

•Manage - We mitigate risks from cybersecurity threats by applying multiple layers of defense to maximize our continued ability to access or utilize an asset or system and minimize threat actors' ability to gain or increase their access to an asset or system. We prioritize defensive mechanisms, including administrative, physical, and technical controls, according to their relative cost and reduction in risk.

We further monitor, test, assess, and update these processes, including working with technology partners, government agencies, regulators, law enforcement, industry groups, and peers to implement practices to guard against an evolving cyber threat environment and to ensure we remain compliant with relevant regulatory requirements. We offer cybersecurity training for corporate employees at headquarters and terminal locations, focusing on reducing human risk through anti-phishing and social engineering exercises. We also carry cybersecurity insurance that provides protection against potential losses arising from certain cybersecurity incidents as part of our cybersecurity risk mitigation strategy.

Integration into our Risk Management Program —Our processes to assess, identify, and manage cybersecurity risks are expressly incorporated into our risk management program, which includes technology as one of the five primary risk categories addressed by our risk program, with cybersecurity risks being one of the three subcategories within the technology risk category. As a result, our risk management leadership team works with the Chief Information Officer ("CIO") and Vice President of Information Technology Security ("VPIT"), which we refer to collectively as "Cybersecurity Leadership," to define the top areas of risk in both the technology and cybersecurity areas, with such risks incorporated into our risk management program. Our risk management leadership team also meets on a quarterly basis with our cross-functional technology risk working group, comprised of leaders across the information technology, operations, internal audit, information security and legal departments, to monitor developments on an ongoing basis in the threat landscape in order to identify and prioritize key cybersecurity threats that may impact the Company.

Incident Response

The Company has a dedicated cybersecurity incident response team, overseen by Cybersecurity Leadership, which is responsible for managing and coordinating the Company’s cybersecurity incident response plans and efforts. This team also collaborates closely with other teams in identifying, protecting from, detecting, responding to, and recovering from cybersecurity incidents. Cybersecurity incidents that meet certain thresholds are escalated to Cybersecurity Leadership and cross-functional teams on an as-needed basis for support and guidance. Additionally, this team tracks potentially material cybersecurity incidents to help identify and analyze them. The Company’s

38

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

cybersecurity incident response team partners with the Company’s internal cybersecurity teams as well as with external legal advisors, communication specialists, government agencies, regulators, law enforcement, vendors, and other key stakeholders as appropriate to respond to cybersecurity incidents. The Company maintains a cybersecurity incident response plan to prepare for and respond to cybersecurity incidents. The incident response plan includes standard processes for reporting and escalating cybersecurity incidents to senior management and the Board as appropriate. Additionally, the Company conducts at least one cybersecurity tabletop exercise on an annual basis, where members of a cross-functional team engage in a simulated cybersecurity incident scenario. This preparedness exercise is intended to provide training for the participants and to help the Company assess its processes and capabilities in addressing major cybersecurity incidents.

Use of Third Parties

The Company engages cybersecurity consultants, auditors, and other third parties to assess and enhance its cybersecurity practices. These third parties conduct assessments, penetration testing, and risk assessments to identify weaknesses and recommend improvements. Additionally, the Company leverages a number of third-party tools and technologies as part of its efforts to enhance cybersecurity functions. This includes a managed security service provider to augment the Company’s dedicated security operations team, an endpoint detection and response system for continuous monitoring, detection, and response capabilities, and a security information and event management solution to automate real-time threat detection, investigation, and prioritization.

We also rely on third-party service providers to support our business and operations, which may include processing of confidential and other sensitive data. We are committed to continuing to develop and enhance our onboarding and monitoring processes for third-party vendors to ensure alignment with best practices. Despite our efforts, it's important to note our service providers are ultimately responsible to establish and uphold their respective cybersecurity programs. We have limited ability to monitor the cybersecurity practices of our service providers and there can be no assurance that we can prevent or mitigate the risk of any compromise or failure in the information systems, software, networks, or other assets owned or controlled by our service providers. Notwithstanding our efforts to mitigate any such risk, there can be no assurance that the compromise or failure of supplier information systems, technology assets, or cybersecurity programs would not have an adverse effect on the security of our information systems.

Risks from Material Cybersecurity Threats

As of the date of this report, the Company has not identified any cybersecurity threats that have materially affected or are reasonably anticipated to have a material effect on the Company. Although the Company has not experienced cybersecurity incidents that are individually, or in the aggregate, material, the Company has experienced cyberattacks in the past, which the Company believes have thus far been mitigated by preventative, detective, and responsive measures put in place by the Company. Further, despite the capabilities, processes, and other security measures we employ that we believe are designed to detect, reduce, and mitigate the risk of cybersecurity incidents, we may not be aware of all vulnerabilities or might not accurately assess the risks of incidents, and such preventative measures cannot provide absolute security and may not be sufficient in all circumstances or mitigate all potential risks. Our business and operations could be materially and adversely impacted by cybersecurity incidents. For a detailed discussion of the Company’s cybersecurity related risks, refer to "Operational Risk" within Part I, Item 1A. Risk Factors of this Annual Report.

Cybersecurity Governance

Board Oversight

The Board is responsible for overseeing management’s assessments of major risks facing the Company and for reviewing options to mitigate such risks. The Board’s oversight of major risks, including cybersecurity risks, occurs at both the full Board level and at the Board committee level through the Nominating and Corporate Governance Committee.

The Board — The Chief Executive Officer, the Chief Financial Officer, the CIO, members of senior management, and other personnel and advisors, as requested by the Board, report on the risks to the Company, including cybersecurity risks, at regularly scheduled meetings of the Board and its committees. Based on these reports, the Board requests follow-up data and presentations to address any specific concerns and recommendations. Additionally, the Board committees have opportunities to report regularly to the entire Board and review with the Board any major issues that arise at the committee level, which may include cybersecurity risks.

39

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

Nominating and Corporate Governance Committee — The Nominating and Corporate Governance Committee, which is comprised entirely of independent directors, reviews with management the Company's technology and cybersecurity frameworks, policies, programs, opportunities, and risk profile both at its regularly scheduled meetings and, if appropriate, in real time. Cybersecurity Leadership, members of the cybersecurity team, or other advisors, as requested by the Nominating and Corporate Governance Committee, report at least quarterly on the Company's technology, data privacy, and cybersecurity strategies and risks. Cybersecurity topics are presented to the Nominating and Corporate Governance Committee on a quarterly basis and generally highlight any significant cybersecurity incidents, the cyber threat landscape, cybersecurity program enhancements, cybersecurity risks and related mitigation activities, and any other relevant cybersecurity topics. Reporting to the Nominating and Corporate Governance Committee is multi-format and includes both live presentations and memoranda. The Board believes that this regular cadence of reporting helps to provide the Nominating and Corporate Governance Committee with an informed understanding of the Company's dynamic cybersecurity program and threat landscape. The Nominating and Corporate Governance Committee further reviews with management the Company's business continuity and disaster recovery plans and capabilities, including our cybersecurity and business interruption insurance coverages, and the effectiveness of the Company's escalation procedures. Based on these management reports, the Nominating and Corporate Governance Committee may request follow-up data and presentations to address any specific concerns and recommendations. In addition to this regular reporting, significant cybersecurity risks or threats may also be escalated by management on an as needed basis to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee may also escalate such issues to the full Board at any time.

Management's Role

The Company has a dedicated cybersecurity organization within its technology department that focuses on current and emerging cybersecurity matters. The Company’s cybersecurity function is led by Cybersecurity Leadership who are actively involved in assessing and managing cybersecurity risks. They are responsible for implementing cybersecurity policies, programs, procedures, and strategies. The responsibilities and relevant experience of each of the Cybersecurity Leaders are listed below:

•The CIO provides leadership for the Company’s technology department, including responsibility for leading organization-wide cybersecurity strategy, policy, and processes. Our CIO has served in this role since June 2024 and has over 25 years of cybersecurity experience, including technology positions at the US Army, Accenture, Advance Auto Parts, Finishline Shoes, and PF Chang's.

•The VPIT, reporting to the CIO, is responsible for the assessment, oversight, and management of our enterprise-wide cybersecurity strategy and governance. Our VPIT has served in this role since 2020 and has significant relevant experience and professional certifications, including nearly 20 years of cybersecurity and infrastructure experience. The VPIT, along with our cybersecurity team, has guided the organization through building a multi-layer cybersecurity program.

The Company's cybersecurity department is comprised of teams that engage in a range of cybersecurity activities such as threat intelligence, security architecture, and incident response. These teams, in coordination with third parties, conduct vulnerability management and penetration testing to identify, classify, prioritize, remediate, and mitigate vulnerabilities. The results of these tests are reviewed with the Nominating and Corporate Governance Committee. Leaders from each team regularly meet with Cybersecurity Leadership to provide visibility into major issues and seek alignment with strategy. As noted above under "Incident Response," the Company’s cybersecurity incident response plan includes standard processes for reporting and escalating cybersecurity incidents to senior management and the Board, as appropriate. Cybersecurity incidents that meet certain thresholds are escalated to Cybersecurity Leadership and cross-functional teams on an as-needed basis for support and guidance. The Company’s incident response team also coordinates with external legal advisors, communication specialists, government agencies, regulators, law enforcement, and other key stakeholders.

Results of Operations — Summary

Notes regarding presentation: A discussion of changes in our results of operations from 2022 to 2023 has been omitted from this Annual Report, but may be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our 2023 Annual Report filed with the SEC on February 22, 2024.

In accordance with accounting treatment applicable to each of our recent acquisitions, Knight-Swift's reported results do not include the operating results of the acquired entities prior to the respective acquisition dates. Accordingly, comparisons between the Company's 2024 results and prior periods may not be meaningful. Refer to Note 1 in Part II, Item 8 of this Annual Report for a list of our recent acquisitions.

Operating Results: 2024 Compared to 2023 — The $99.5 million decrease in net income attributable to Knight-Swift to $117.6 million in 2024 from $217.1 million in 2023, includes the following:

•Contributor — $129.6 million decrease in operating income within our Truckload segment, primarily due to a 7.6% decrease in average revenue per tractor, which includes the results of U.S. Xpress. Excluding U.S. Xpress, revenue, excluding fuel surcharge, per tractor increased 1.6% year-over-year.

•Contributor — $31.5 million decrease in operating income from our LTL segment as a result of increased costs related to expanding our LTL service area and a 4.1% decrease in weight per shipment.

•Contributor — $20.1 million decrease in operating income within our Logistics segment driven by a 11.1% decrease in load count.

•Contributor — $49.1 million increase in net interest expense primarily due to an increase in interest rates and increase in outstanding borrowings.

•Offset — $85.4 million decrease in operating loss within our All Other Segments, largely as a result of exiting the third-party insurance business at the end of the first quarter of 2024.

•Offset — $22.6 million increase in "Other income (expenses), net," primarily driven by a mark-to-market adjustment in 2024 related to certain purchase price obligations associated with the acquisition of U.S. Xpress.

•Offset — $21.8 million decrease in consolidated income tax expense, primarily due to a decrease in income before income taxes. This resulted in a 2024 effective tax rate of 22.1% and a 2023 effective tax rate of 20.3%.

•Offset — $1.0 milliondecrease in operating loss within our Intermodal segment driven by a 3.5% increase in load count.

Revenue

•Our truckload services include irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border transportation of various products, goods, and materials for our diverse customer base with approximately 16,300 irregular route and 6,500 dedicated tractors.

•Our LTL business, which was initially established in 2021 through the ACT Acquisition and later the MME and DHE acquisitions, provides our customers with regional LTL transportation service through our growing network of approximately 170 facilities and a door count of approximately 6,060. Our LTL segment operates approximately 3,600 tractors and approximately 9,600 trailers, including equipment used for ACT's and MME's dedicated and other businesses. The LTL segment also provides national coverage to our customers by utilizing partner carriers for areas outside of our direct network.

•Our Logistics and Intermodal segments provide a multitude of shipping solutions, including additional sources of truckload capacity and alternative transportation modes, by utilizing our vast network of third-party capacity providers and rail providers, as well as certain logistics and freight management services. We continue to offer power-only services through our Logistics segment by leveraging our fleet of approximately 93,000 trailers as of December 31, 2024.

•All Other Segments include support services provided to our customers and third-party carriers including equipment maintenance, equipment leasing, warehousing, trailer parts manufacturing, warranty services, and insurance for independent contractors, as well as insurance for affiliated carriers through the first quarter of 2024. All Other Segments also include certain corporate expenses (such as legal settlements and accruals, certain impairments, and amortization of intangibles related to the 2017 Merger and various acquisitions).

•In addition to the revenues earned from our customers for the trucking and non-trucking services discussed above, we also earn fuel surcharge revenue from our customers through our fuel surcharge programs, which serve to recover a majority of our fuel costs. This generally applies only to loaded miles for our Truckload and LTL segments and typically does not offset non-paid empty miles, idle time, nor out-of-route miles driven. Fuel surcharge programs involve a computation based on the change in national or regional fuel prices. These programs may update as often as weekly, but typically require a specified minimum change in fuel cost to prompt a change in fuel surcharge revenue. Therefore, many of these programs have a time lag between when fuel costs change and when the change is reflected in fuel surcharge revenue for our Truckload and LTL segments.

Expenses

Our most significant expenses typically vary with miles traveled and include fuel, driving associate-related expenses (such as wages and benefits), and services purchased from third-party service providers (including other trucking companies, railroad and drayage providers, and independent contractors). Maintenance and tire expenses, as well as the cost of insurance and claims generally vary with the miles we travel but also have a controllable component based on safety performance, fleet age, operating efficiency, and other factors. Our primary fixed costs are depreciation and lease expense for revenue equipment and terminals, non-driver employee compensation, amortization of intangible assets, and interest expenses.

Segment Review

Truckload Segment

We generate revenue in the Truckload segment primarily through irregular route, dedicated, refrigerated, flatbed, expedited, and cross-border service offerings, with approximately 16,300 irregular route tractors and approximately 6,500 dedicated route tractors in use during 2024. Generally, we are paid a predetermined rate per mile or per load for our truckload services. Additional revenues are generated by charging for tractor and trailer detention, loading and unloading activities, dedicated services, other specialized services, and through the collection of fuel surcharge revenue to mitigate the impact of increases in the cost of fuel. The main factors that affect the revenue generated by our Truckload segment are rate per mile from our customers, the percentage of miles for which we are compensated, and the number of loaded miles we generate with our equipment.

The most significant expenses in the Truckload segment are primarily variable and include fuel and fuel taxes, driving associate-related expenses (such as wages, benefits, training, and recruitment), and costs associated with independent contractors primarily included in "Purchased transportation" in the consolidated statements of comprehensive income. Maintenance expense (which includes costs for replacement tires for our revenue equipment) and insurance and claims expenses have both fixed and variable components. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, fleet age, efficiency, and other factors. The main fixed costs in the Truckload segment are depreciation and rent expenses from tractors, trailers, and terminals, as well as compensating our non-driver employees.

3Includes 20,644 and 18,821 company-owned tractors for 2024 and 2023, respectively.

4Average trailers includes 8,985 and 8,724 trailers from our All Other Segments for 2024 and 2023, respectively.

2024 Compared to 2023 — Our Truckload segment revenue, excluding fuel surcharge and intersegment transactions, increased 9.4 % year-over-year, driven by a 13.6% increase in loaded miles. Revenue per loaded mile, excluding fuel surcharge and intersegment transactions, declined 3.8% year-over-year. The 2024 Adjusted Operating Ratio increased 340 basis points year-over-year to 95.6%.

We believe our extensive trailer fleet, which has grown to approximately 93,000 trailers as of the end of 2024, positions us to provide valuable capacity, flexibility, and efficiency to our customers through our Truckload and Logistics segments. We are focused on disciplined pricing and capacity commitments that we expect will position our business to continue to respond as market conditions improve.

LTL Segment

Our LTL segment provides regional direct service and serves our customers' national transportation needs by utilizing key partner carriers for coverage areas outside of our network. We primarily generate revenue by transporting freight for our customers through our core LTL services.

Our revenues are impacted by shipment volume and tonnage levels that flow through our network. Additional revenues are generated through fuel surcharges and accessorial services provided during transit from shipment origin to destination. We focus on the following multiple revenue generation factors when reviewing revenue yield: revenue per hundredweight, revenue per shipment, weight per shipment, and length of haul. Fluctuations within each of these metrics are analyzed when determining the revenue quality of our customers' shipment density.

Our most significant expenses are related to direct costs associated with the transportation of our freight moves including direct salary, wage and benefit costs, fuel expense, and depreciation expense associated with revenue equipment costs. Other expenses associated with revenue generation that can fluctuate and impact operating results are insurance and claims expense, as well as maintenance costs of our revenue equipment. These expenses can be influenced by multiple factors including our safety performance, equipment age, and other factors. A key component to lowering our operating costs is labor efficiency within our network. We continue to focus on technological advances to improve the customer experience and reduce our operating costs.

Non-GAAP: Adjusted Operating Ratio 1 2 90.1 % 85.3 % 480 bps

LTL average length of haul (miles) 2 589 553 6.5 %

4Includes 876 and 723 trailers from ACT's and MME's dedicated and other businesses for 2024 and 2023, respectively.

2024 Compared to 2023 — Our LTL segment grew revenue, excluding fuel surcharge, 16.2% as shipments per day increased 9.8% year-over-year, which includes the acquisition of DHE on July 30, 2024. Revenue per hundredweight, excluding fuel surcharge, increased 11.4%, while revenue per shipment, excluding fuel surcharge, increased by 6.7%, reflecting a 4.1% decrease in weight per shipment. This segment produced a 90.1% Adjusted Operating Ratio in 2024, while Adjusted Operating Income decreased 21.6% year-over-year primarily due to start-up costs and early-stage operations at our recently opened facilities and costs related to the system integration of DHE, which was completed during the fourth quarter of 2024.

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

During 2024, we opened 37 additional service centers and added 14 more facilities through the DHE Acquisition in the third quarter. Overall, our organic and inorganic expansion activities in 2024 added approximately 1,430 doors, representing over 30% growth in our door count from the beginning of the year. We believe this meaningfully impacts the reach of our service offering and ultimately will increase the density of our network. We believe the investments in our network during 2024 bring opportunities to service additional freight and customers, though the associated set-up costs and initial operational inefficiencies are near-term headwinds to improving margins. Our focus for 2025 will be to grow shipment volumes at these locations, particularly as they participate in the bid cycle, which we expect will help drive both revenue and margin expansion in the business. While we currently anticipate that our pace of facility additions will slow in 2025, we continue to look for both organic and inorganic opportunities to geographically expand our footprint within the LTL market.

Logistics Segment

The Logistics segment is less asset-intensive than the Truckload and LTL segments and is dependent upon capable non-driver employees, modern and effective information technology, and third-party capacity providers. Logistics revenue is primarily generated by its brokerage operations. We generate additional revenue by offering specialized logistics solutions (including, but not limited to, trailing equipment, origin management, surge volume, disaster relief, special projects, and other logistics needs). Logistics revenue is mainly affected by the rates we obtain from customers, the freight volumes we ship through third-party capacity providers, and our ability to secure third-party capacity providers to transport customer freight.

The most significant expense in the Logistics segment is purchased transportation that we pay to third-party capacity providers, which is primarily a variable cost, and is included in "Purchased transportation" in the consolidated statements of comprehensive income. Variability in this expense depends on truckload capacity, availability of third-party capacity providers, rates charged to customers, current freight demand, and customer shipping needs. Fixed Logistics operating expenses primarily include non-driver employee compensation and benefits recorded in "Salaries, wages, and benefits," as well as depreciation and amortization expense recorded in "Depreciation and amortization of property and equipment" in the consolidated statements of comprehensive income.

2024 Compared to 2023 — Logistics Adjusted Operating Ratio was 95.1%, with a gross margin of 17.5% in 2024, compared to 18.7% in 2023. Logistics load count, excluding U.S. Xpress, declined by 26.3% year-over-year. With the inclusion of U.S. Xpress logistics volumes, load count declined by 11.1% year-over-year. Revenue per load increased by 9.9% year-over-year, but was offset by increased purchase transportation costs. We remain disciplined on price and diligent in carrier qualification to provide value to customers while maintaining profitability. We continue to leverage our power-only capabilities to complement our asset business, build a broader and more diversified freight portfolio, and to enhance the returns on our capital assets.

Intermodal Segment

The Intermodal segment complements our regional operating model, while also allowing us to better serve customers in longer haul lanes, and reduces our investment in fixed assets. Through the Intermodal segment, we generate revenue by moving freight over the rail in our containers and other trailing equipment, combined with revenue for drayage to transport loads between railheads and customer locations. The most significant expense in the Intermodal segment is the cost of purchased transportation that we pay to third-party capacity providers (including rail providers), which is primarily variable and included in "Purchased transportation" in the consolidated statements of comprehensive income. While rail pricing is primarily determined on an annual basis, purchased transportation varies as it relates to rail capacity, freight demand, and customer shipping needs. The main fixed costs in the Intermodal segment are depreciation of our company tractors related to drayage, containers, and chassis, as well as non-driver employee compensation and benefits.

2Includes 561 and 577 company-owned tractors for 2024 and 2023, respectively.

2024 Compared to 2023 — Intermodal operated with a 102.4% operating ratio in 2024. While load count increased year-over-year by 3.5%, total revenue decreased 5.7% year-over-year to $387.2 million as revenue per load declined 8.9%, resulting from soft demand and competitive truck capacity.

We remain focused on growing our load count with disciplined pricing across a diverse group of customers, although we expect future results will be impacted by the cost of alternative truck capacity.

All Other Segments

Our All Other Segments include support services provided to our customers and third-party carriers including equipment maintenance, equipment leasing, warehousing, trailer parts manufacturing, warranty services, and insurance for independent contractors, as well as insurance for affiliated carriers through the first quarter of 2024. Our All Other Segments also include certain corporate expenses (such as legal settlements and accruals, certain impairments, and $46.7 million in annual amortization of intangibles related to the 2017 Merger and various acquisitions).

(Dollars in thousands) Increase (decrease)

2024 Compared to 2023 —Revenue declined 42.3% year-over-year, largely as a result of winding down our third-party carrier insurance program in the first quarter of 2024. The $26.2 million operating loss within our All Other Segments is primarily driven by the intangible amortization during 2024. The operating loss within our All Other Segments improved from the prior year, which had included a $125.5 million operating loss for the third-party insurance business during 2023.

Results of Operations — Consolidated Operating and Other Expenses

Consolidated Operating Expenses

The following tables present certain operating expenses from our consolidated statements of comprehensive income, including each operating expense as a percentage of total revenue and as a percentage of revenue, excluding truckload and LTL fuel surcharge. Truckload and LTL fuel surcharge revenue can be volatile and is primarily dependent upon the cost of fuel, rather than operating expenses unrelated to fuel. Therefore, we believe that revenue, excluding truckload and LTL fuel surcharge is a better measure for analyzing many of our expenses and operating metrics.

(Dollars in thousands) Increase (decrease)

% of revenue, excluding truckload and LTL fuel surcharge 42.7 % 39.3 % 340 bps

Salaries, wages, and benefits expense is primarily affected by the total number of miles driven by and rates we pay to our company driving associates, and employee benefits including healthcare, workers' compensation, and other benefits. To a lesser extent, non-driver employee headcount, compensation, and benefits affect this expense. Driving associate wages represent the largest component of salaries, wages, and benefits expense.

Several ongoing market factors have reduced the pool of available driving associates, contributing to a challenging driver sourcing market, which we believe will continue. Having a sufficient number of qualified driving associates is a significant headwind, although we continue to seek ways to attract and retain qualified driving associates, including heavily investing in our recruiting efforts, our driving academies, technology, equipment, and terminals that improve the experience of driving associates. We expect labor costs (related to both driving associates and non-driver employees) to remain inflationary, which we expect will result in additional increases in pay and benefits expenses in the future, thereby increasing our salaries, wages, and benefits expense.

2024 Compared to 2023 — The increase in consolidated salaries, wages, and benefits includes a $263.6 million increase as a result of including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023 as well as an $87.0 million increase from LTL wages primarily due to the DHE Acquisition.

(Dollars in thousands) Increase (decrease)

% of total revenue 11.8 % 12.3 % (50 bps)

% of revenue, excluding truckload and LTL fuel surcharge 13.2 % 13.9 % (70 bps)

Fuel expense consists primarily of diesel fuel expense for our company-owned tractors. The primary factors affecting our fuel expense are the cost of diesel fuel, the fuel economy of our equipment, and the miles driven by company driving associates.

Our fuel surcharge programs help to offset increases in fuel prices, but generally apply only to loaded miles for our Truckload and LTL segments and typically do not offset non-paid empty miles, idle time, or out-of-route miles driven. Typical fuel surcharge programs involve a computation based on the change in national or regional fuel prices. These programs may update as often as weekly, but typically require a specified minimum change in fuel cost to prompt a change in fuel surcharge revenue for our Truckload and LTL segments. Therefore, many of these programs have a time lag between when fuel costs change and when the change is reflected in fuel surcharge revenue. Due to this time lag, our fuel expense, net of fuel surcharge, negatively impacts our operating income during periods of sharply rising fuel costs and positively impacts our operating income during periods of falling fuel costs. We continue to utilize our fuel efficiency initiatives such as trailer blades, idle-control, management of tractor speeds, fleet updates for more fuel-efficient engines, management of fuel procurement, and driving associate training programs that we believe contribute to controlling our fuel expense.

2024 Compared to 2023 — The decrease in consolidated fuel expense was primarily due to lower average weekly DOE fuel prices of $3.76 per gallon in 2024 compared to $4.20 per gallon in 2023, mostly offset by the increase in fuel expense as a result of including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023.

(Dollars in thousands) Increase (decrease)

% of total revenue 7.4 % 6.6 % 80 bps

% of revenue, excluding truckload and LTL fuel surcharge 8.3 % 7.5 % 80 bps

Operations and maintenance expense consists of direct operating expenses, such as driving associate hiring and recruiting expenses, equipment maintenance, and tire expense. Operations and maintenance expenses are typically affected by the age of our company-owned fleet of tractors and trailers and the miles driven. We expect the driver market to remain competitive throughout 2025, which could increase future driving associate development and recruiting costs and negatively affect our operations and maintenance expense. We expect to continue refreshing our tractor fleet in the coming quarters, subject to availability of new revenue equipment, to maintain the average age of our equipment.

2024 Compared to 2023 — The increase in consolidated operations and maintenance expense includes a $57.5 million increase as a result of including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023 and a $10.0 million increase in maintenance primarily related to tractor and trailer tire expenses, excluding U.S. Xpress.

(Dollars in thousands) Increase (decrease)

% of total revenue 5.6 % 8.5 % (290 bps)

% of revenue, excluding truckload and LTL fuel surcharge 6.3 % 9.7 % (340 bps)

Insurance and claims expense consists of premiums for liability, physical damage, and cargo, and will vary based upon the frequency and severity of claims, our level of self-insurance, and premium expense. In recent years, insurance carriers have raised premiums for many businesses, including transportation companies. As a result, our insurance and claims expense could increase in the future, or we could raise our self-insured retention limits or reduce excess coverage limits when our policies are renewed or replaced. Insurance and claims expense also varies based on the number of miles driven by company driving associates and independent contractors, the frequency and severity of accidents, trends in development factors used in actuarial accruals, and developments in prior-year claims. In future periods, our higher self-insured retention limits and lower excess coverage limits may cause increased volatility in our consolidated insurance and claims expense.

In the first quarter of 2024, we exited our third-party insurance business, which offered insurance products to third-party carriers, earning premium revenues, which were partially offset by increased insurance reserves, and which exposed us to claims and inability to collect premiums. We ceased operating this business in the first quarter of 2024, which we expect will result in some reduction of volatility as we will no longer be exposed to new claims from the third-party insurance business.

2024 Compared to 2023 — Consolidated insurance and claims expense decreased primarily due to a $259.7 million decrease in insurance costs associated with the third-party insurance business, which we exited in the first quarter of 2024. This decrease was partially offset by an increase of $42.2 million in insurance and claims expense as a result of including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023.

2024 Compared to 2023 — The increase in consolidated operating taxes and licenses expense is primarily due to the inclusion of $7.5 million of operating taxes and licenses expense from including U.S Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023.

Communications expense is comprised of costs associated with our tractor and trailer tracking systems, information technology systems, and phone systems.

2024 Compared to 2023 — The increase in consolidated communications expense is primarily due to the inclusion of $2.0 million of communications expense from including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023.

Depreciation relates primarily to our owned tractors, trailers, buildings, electronic logging devices, other communication units, and other similar assets. Changes to this fixed cost are generally attributed to increases or decreases in company-owned equipment, the relative percentage of owned versus leased equipment, and fluctuations in new equipment purchase prices. Depreciation can also be affected by the cost of used equipment that we sell or trade and the replacement of older used equipment. Management periodically reviews the condition, average age, and reasonableness of estimated useful lives and salvage values of our equipment and considers such factors in light of our experience with similar assets, used equipment market conditions, and prevailing industry practices.

2024 Compared to 2023 — The increase in consolidated depreciation and amortization of property and equipment includes a $65.7 million increase of expense as a result of including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023. This was partially offset by a decrease in tractor and trailer depreciation as a result of the decrease in the tractor and trailer counts for our legacy business, excluding U.S. Xpress.

We anticipate that depreciation and amortization expense will increase, as a percentage of revenue, excluding truckload and LTL fuel surcharge, as we intend to purchase, rather than enter into operating leases, for a majority of our revenue equipment, terminal improvements, or terminal expansions in 2025.

Amortization of intangibles relates to intangible assets identified with the 2017 Merger, ACT Acquisition, U.S. Xpress Acquisition, and other acquisitions. See Note 4 and Note 8 in Part II, Item 8, of this Annual Report for further details regarding the Company's intangible assets, historical amortization, and anticipated future amortization.

2024 Compared to 2023 — The increase in consolidated amortization of intangibles for 2024 is primarily attributed to the U.S. Xpress and DHE acquisitions. See Note 4 in Part II, Item 8, of this Annual Report for more details regarding our acquisitions.

Rental expense consists primarily of payments for revenue equipment assumed in the U.S. Xpress Acquisition, as well as our terminals and other real estate leases.

2024 Compared to 2023 — The increase in consolidated rental expense is primarily related to the inclusion of $38.0 million from including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023. Additional increases relate to the incorporation of new facilities as we expand our LTL network and were partially offset by a decrease in the rental expense for revenue equipment.

% of total revenue 15.8 % 16.7 % (90 bps)

Purchased transportation expense is comprised of payments to independent contractors in our trucking operations, as well as payments to third-party capacity providers related to logistics, freight management, and non-trucking services in our logistics and intermodal businesses. Purchased transportation is generally affected by capacity in the market, as well as changes in fuel prices. As capacity tightens, our payments to third-party capacity providers and to independent contractors tend to increase. Additionally, as fuel prices increase, payments to third-party capacity providers and independent contractors increase. Purchased transportation expense may also fluctuate as a percentage of revenue based on the relative growth of our logistics and intermodal businesses as compared to our full truckload and LTL businesses.

2024 Compared to 2023 —The decrease in consolidated purchased transportation expense is primarily due to decreased load volume within our logistics business and lower miles driven by independent contractors, partially offset by $152.2 million of additional purchased transportation expense from including U.S. Xpress' full year expense in 2024 compared to its partial year expense in 2023 following the U.S. Xpress Acquisition in July 2023.

(Dollars in thousands) Increase (decrease)

Interest income — Interest income includes interest earned from financing revenue equipment to independent contractors, as well as interest earned from our investments.

2024 Compared to 2023 — The decrease in consolidated interest income is primarily due to the lower balances in our interest yielding cash accounts during 2024.

Interest expense —Interest expense is comprised of debt and finance lease interest expense, as well as amortization of deferred loan costs.

2024 Compared to 2023 — Consolidated interest expense increased due to an increase in interest rates during 2024 and an increase in the average debt balance. Additional details regarding our debt are discussed in Note 13 in Part II, Item 8 of this Annual Report.

Other income, net —Other income, net is primarily comprised of (gains) and losses from our various equity investments, as well as certain other non-operating income and expense items that may arise outside of the normal course of business.

2024 Compared to 2023 — The increase in consolidated other income, net is primarily due to the $36.6 million benefit for the mark-to-market adjustment in 2024 related to certain purchase price obligations associated with the acquisition of U.S. Xpress, partially offset by a $12.1 million write-off of a minority investment in a transportation-adjacent technology venture which ceased operations in the third quarter of 2024.

See Note 4 in Part II, Item 8, of this Annual Report for more details regarding our purchase price obligations in connection with the U.S. Xpress Acquistion.

Income tax expense — In addition to the discussion below, Note 11 in Part II, Item 8 of this Annual Report provides further analysis related to income taxes.

2024 Compared to 2023 — The decrease in consolidated income tax expense was primarily due to a reduction in pre-tax earnings in addition to tax benefits from mark-to-market adjustments and decreased state tax expense due to changes in rates. These were partially offset by a decrease in the release of valuation allowance, reductions in foreign currency benefits, and decreases in stock compensation deductions. As a result, the effective tax rate for 2024 was 22.1% as compared to the 2023 effective tax rate of 20.3%.

Non-GAAP Financial Measures

The terms "Adjusted Net Income Attributable to Knight-Swift," "Adjusted EPS," "Adjusted Operating Income," "Adjusted Operating Expenses," "Adjusted Operating Ratio," and "Free Cash Flow," as we define them, are not presented in accordance with GAAP. These financial measures supplement our GAAP results in evaluating certain aspects of our business. We believe that using these measures improves comparability in analyzing our performance because they remove the impact of items from our operating results that, in our opinion, do not reflect our core operating performance. Management and the Board focus on Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, Adjusted Operating Income, Adjusted Operating Expenses and Adjusted Operating Ratio as key measures of our performance, all of which are reconciled to the most comparable GAAP financial measures and further discussed below. Management and the Board use Free Cash Flow as a key measure of our liquidity. Free Cash Flow does not represent residual cash flow available for discretionary expenditures. We believe our presentation of these non-GAAP financial measures is useful because it provides investors and securities analysts the same information that we use internally for purposes of assessing our core operating performance.

Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, Adjusted Operating Income, Adjusted Operating Expenses, Adjusted Operating Ratio, and Free Cash Flow are not substitutes for their comparable GAAP financial measures, such as net income, cash flows from operating activities, operating income, or other measures prescribed by GAAP. There are limitations to using non-GAAP financial measures. Although we believe that they improve comparability in analyzing our period to period performance, they could limit comparability to other companies in our industry if those companies define these measures differently. Because of these limitations, our non-GAAP financial measures should not be considered measures of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.

Pursuant to the requirements of Regulation G, the following tables reconcile GAAP consolidated net income attributable to Knight-Swift to non-GAAP consolidated Adjusted Net Income attributable to Knight-Swift, GAAP consolidated earnings per diluted share to non-GAAP consolidated Adjusted EPS, GAAP consolidated operating ratio to non-GAAP consolidated Adjusted Operating Ratio, GAAP reportable segment operating income to non-GAAP reportable segment Adjusted Operating Income, GAAP reportable segment operating expenses to non-GAAP segment Adjusted Operating Expenses, GAAP reportable segment operating ratio to non-GAAP reportable segment Adjusted Operating Ratio, and GAAP cash flow from operations to non-GAAP Free Cash Flow.

Note regarding presentation: A discussion of changes in our results of operations from 2022 to 2023 has been omitted from this Annual Report, but may be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our 2023 Annual Report filed with the SEC on February 22, 2024.
