ITEM 1. BUSINESS

Certain acronyms and terms used throughout this Annual Report are specific to our company, commonly used in our industry, or are otherwise frequently used throughout our document. Definitions for these acronyms and terms are provided in the "Glossary of Terms," available in the front of this document.

Company Overview

Knight-Swift Transportation Holdings Inc. is North America's largest truckload carrier and a provider of transportation solutions, from its Phoenix, Arizona headquarters. The Company provides multiple truckload transportation, intermodal, and logistics services using a nationwide network of business units and terminals in the US and Mexico to serve customers throughout North America. In addition to its truckload services, Knight-Swift also contracts with third-party capacity providers to provide a broad range of truckload services to its customers while creating quality driving jobs for our driving associates and successful business opportunities for independent contractors.

During 2020, we covered 1.5 billion loaded miles for shippers throughout North America, contributing to consolidated total revenue of $4.7 billion and consolidated operating income of $564.4 million. During 2020, the Trucking segment operated an average of 18,448 tractors (comprised of 16,379 company tractors and 2,069 independent contractor tractors) and 57,722 trailers. Additionally, the Intermodal segment operated an average of 577 tractors and 10,604 intermodal containers. Our three reportable segments are Trucking, Logistics, and Intermodal.

We have historically grown through a combination of organic growth, as well as through mergers and acquisitions (discussed below). Mergers and acquisitions have enhanced Knight's and Swift's businesses and service offerings with additional terminals, driving associates, revenue equipment, and capacity. Our multiple service offerings, capabilities, and transportation modes enable us to transport, or arrange transportation for, general commodities for our diversified customer base throughout the contiguous US and Mexico using our equipment, information technology, and qualified driving associates and non-driver employees. We are committed to providing our customers with a wide range of truckload, intermodal, and logistics services and continuing to invest considerable resources toward developing a range of solutions for our customers across multiple service offerings and transportation modes. Our overall objective is to provide truckload, intermodal, and logistics services that, when combined, lead the industry in margin and growth, while providing efficient and cost-effective solutions for our customers.

Business Combinations and Investments

2017 Merger

On September 8, 2017, we became Knight-Swift Transportation Holdings Inc. upon the effectiveness of the 2017 Merger. We accounted for the 2017 Merger using the acquisition method of accounting in accordance with GAAP. GAAP requires that either Knight or Swift is designated as the acquirer for accounting and financial reporting purposes ("Accounting Acquirer"). Based on the evidence available, Knight was designated as the Accounting Acquirer while Swift was the acquirer for legal purposes. Therefore, Knight’s historical results of operations replaced Swift’s historical results of operations for all periods prior to the 2017 Merger.

Historical Acquisitions

Knight — Since 1999, Knight has acquired the outstanding stock of six short-to-medium haul truckload carriers, including Iowa-based Barr-Nunn (acquired in 2014), and Virginia-based Abilene (acquired in 2018). On February 1, 2021, Knight acquired a majority ownership position in Eleos, a Greenville, South Carolina based software provider, specializing in mobile driving workflow platforms.

Swift — Since 1966, Swift has completed fifteen acquisitions, including the 2013 acquisition of Central Refrigerated Transportation, LLC (formerly Central Refrigerated Transportation, Inc.). On January 1, 2020 Swift acquired a warehousing company to complement its suite of services.

Joint Ventures

Industry and Competition

Truckload carriers represent the largest part of the transportation supply chain for most retail and manufactured goods in North America and typically transport a full trailer (or container) of freight for a single customer from origin to destination without intermediate sorting and handling. Generally, the truckload industry is compensated based on miles, whereas the less-than-truckload industry is compensated based on package size and/or weight. Overall, the US trucking industry is large, fragmented, and highly competitive. We compete with thousands of truckload carriers, most of whom operate significantly smaller fleets than we do. Our trucking segments compete with other motor carriers for the services of driving associates, independent contractors, and management employees. To a lesser extent, our intermodal and logistics businesses compete with railroads, less-than-truckload carriers, logistics providers, and other transportation companies. Our logistics businesses compete with other logistics companies for the services of third-party capacity providers and management employees.

Our industry has encountered the following major economic cycles:

Period Economic Cycle

The principal means of competition in our industry are customer service, capacity, and price. In times of strong freight demand, customer service and capacity become increasingly important, and in times of weak freight demand, pricing becomes increasingly important. Most truckload contracts (other than dedicated contracts) do not guarantee truck availability or shipment volumes. Pricing is influenced by supply and demand.

The trucking industry faces the following primary challenges, which we believe we are well-positioned to address, as discussed under "Our Competitive Strengths" and "Our Mission and Company Strategy," below:

•tightening industry capacity;

•cumulative impacts of regulatory initiatives, such as ELDs, hours-of service limitations for drivers, and others;

•uncertainty in the economic environment, including changing supply chain and consumer spending patterns;

•driver shortages;

•increased insurance costs as significant verdicts and settlement amounts for accident claims impact the industry;

•significant and rapid fluctuations in fuel prices; and

•increased prices for new revenue equipment, design changes of new engines, and volatility in the used equipment sales market.

Growth Strategies

Customers and Marketing

Marketing

Our marketing mission is to be a strategic, efficient transportation capacity partner for our customers by providing truckload and logistics solutions customizable to the unique needs of our customers. We deliver these capacity solutions through our network of owned assets, independent contractors, third-party capacity providers, and rail providers. The diverse and premium services we offer provide a comprehensive approach to providing ample supply chain solutions to our customers. At December 31, 2020, we had a sales staff of approximately 100 individuals across the US and Mexico, who work closely with management to establish and expand accounts. Our sales and marketing leaders are members of our senior management team, who are assisted by other sales professionals in each segment. Our sales team emphasizes our industry-leading service, environmental leadership, and our ability to accommodate a variety of customer needs, provide consistent capacity, and financial strength and stability.

Customers

Our customers are typically large corporations in the retail (including discount and online retail), food and beverage, consumer products, paper products, transportation and logistics, housing and building, automotive, and manufacturing industries. Many of our customers have extensive operations, geographically distributed locations, and diverse shipping needs.

Consistent with industry practice, our typical customer contracts (other than dedicated contracts) do not guarantee shipment volumes by our customers or truck availability by us. This affords us and our customers some flexibility to negotiate rates in response to changes in freight demand and industry-wide truck capacity. Our dedicated services within the Trucking segment assign particular driving associates and revenue equipment to prescribed routes,

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

pursuant to multi-year agreements. This dedicated service provides individual customers with a guaranteed source of capacity, and allows our driving associates to have more predictable schedules and routes. Under our dedicated transportation services, we provide driving associates, equipment, maintenance, and, in some instances, transportation management services that supplement the customer's in-house transportation department.

A majority of our terminals are linked to our corporate information technology system in our Phoenix headquarters. The capabilities of this system and its software enhance our operating efficiency by providing cost-effective access to detailed information concerning equipment location and availability, shipment tracking, on-time delivery status, and other specific customer requirements. The system also enables us to respond promptly and accurately to customer requests and assists us in geographically matching available equipment with customer loads. Additionally, our customers can track shipments and obtain copies of shipping documents via our website. We also provide electronic data interchange services to customers desiring these services.

We believe our fleet capacity, terminal network, customer service and breadth of services offer a competitive advantage to major shippers, particularly in times of rising freight volumes when shippers must quickly access capacity across multiple facilities and regions.

We strive to maintain a diversified customer base. Services provided to our largest customer generated 16.8% and 13.3% of total revenue in 2020 and 2019, respectively. Revenue generated by our largest customer is reported in each of our reportable operating segments. No other customer accounted for 10% or more of total revenue in 2020 or 2019.

Our top 25 customers drive a substantial portion of our total revenue, as follows:

•In 2020, our top 25, top 10, and top 5 customers accounted for 56.5%, 40.8%, and 30.7% of our total revenue, respectively.

•In 2019, our top 25, top 10, and top 5 customers accounted for 49.7%, 33.5%, and 25.5% of our total revenue, respectively.

Revenue Equipment

We operate a modern fleet of company tractors to help attract and retain driving associates, promote safe operations, and reduce maintenance and repair costs.

In 2020, we obtained the majority of our revenue equipment through cash purchases, and in the future, we will continue to monitor leasing opportunities. We typically obtain tractors and trailers manufactured to our specifications in order to meet a wide variety of customer needs. Growth of our tractor and trailer fleet is determined by market conditions and our experience and expectations regarding equipment utilization. In acquiring revenue equipment, we consider a number of factors, including economy, price, rate, economic environment, technology, warranty terms, manufacturer support, driving associate comfort, and resale value. We maintain strong relationships with our equipment vendors and have the financial flexibility to react as market conditions dictate.

Our current approach is to replace our tractors between 36 months and 60 months after purchase and to replace our trailers over a seven- to fifteen-year period. Changes in the current market for used tractors and trailers, regulatory changes, and difficult market conditions faced by tractor and trailer manufacturers, may result in price increases that may affect the period of time for which we operate our equipment.

Our newer equipment has enhanced features, which we believe tends to lower the overall life cycle costs by reducing safety-related expenses, lowering repair and maintenance expenses, improving fuel economy, and improving driving associate satisfaction. In 2021 and beyond, we will continue to monitor the appropriateness of this relatively short tractor trade-in cycle against the lower capital expenditure and financing costs of a longer tractor trade-in cycle, based on current and future business needs.

Human Capital

Employees

The strength of our company is our people, working together with common goals. There were approximately 22,700 full-time employees in our total headcount of approximately 22,900 employees as of December 31, 2020, which was comprised of:

Company driving associates (including driver trainees) 17,400

Technicians and other equipment maintenance personnel 1,200

Corporate and terminal leadership and support personnel 4,300

As of December 31, 2020, we had approximately 900 Trans-Mex driving associates in Mexico that were represented by a union.

Company Driving Associates

We recognize that the recruitment, training, and retention of a professional driving associate workforce, which is one of our most valuable assets, is essential to our continued growth and meeting the service requirements of our customers. In order to attract and retain safe driving associates who are committed to the highest levels of customer service and safety, we focus our operations for driving associates around a collaborative and supportive team environment. To help retain employees we provide late model and comfortable equipment, direct communication with senior management, competitive wages and benefits, and other incentives designed to encourage driving associate safety, retention, and long-term employment. Some examples of these incentive programs include our Million Miler, military apprenticeship, and Drive for a Degree programs. To help recruit drivers, we have established various driving academies across the US. Our academies are strategically located in areas where external driver-training organizations were lacking. In other areas of the US, we have contracted with driver training schools, which are managed by third parties. There are certain minimum qualifications for candidates to be accepted into the academy, including passing the DOT physical examination and drug/alcohol screening.

Terminal Staff

Most of our large terminals are staffed with terminal leaders, fleet leaders, driver leaders, planners, safety coordinators, shop leaders, technicians, and customer service representatives. Our terminal leaders work with driver leaders, customer service representatives, and other operations personnel to coordinate the needs of both our customers and our driving associates. Terminal leaders are also responsible for serving existing customers in their areas. Fleet leaders supervise driver leaders, who are responsible for the general operation of our trucks and their driving associates, focusing on driving associate retention, productivity per truck, fuel consumption, fuel efficiency (with respect to driver-controllable idle time), safety, and scheduled maintenance. Customer service representatives are assigned specific customers to ensure specialized, high-quality service, and frequent customer contact.

Diversity and Inclusion

We are committed to fostering a diverse workforce and an inclusive environment, which among other things, is supported by our hiring practices, employee training programs, formal and informal diversity and inclusion networks, as well as our employee resource group. Our employee resource group, sponsored and supported by leadership, is integral to ensuring different voices and perspectives contribute to our strategy for long term profitable growth.

Succession Planning and Talent Management

We regularly review talent development and succession plans to identify and develop a pipeline of talent to maintain business operations. We understand the potential costs and risks of bringing in an outside executive officer in today’s environment, and that businesses are often, but not always, more successful in promoting internal candidates. Accordingly, the Board makes an effort to identify potential successors for those positions long in advance of any potential positional vacancies, perform skills gap analyses for those internal candidates, and provide training and exposure on those gap areas to those candidates in order to develop better potential successors. The Board is primarily responsible for succession planning for the CEO, but also participates in succession planning discussions for other executive officer positions. We believe that our culture, compensation structure, long-term

11

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

equity program, and robust training and development program provide motivation for talented leaders to remain with the Company.

Independent Contractors

In addition to Knight-Swift-employed driving associates, we enter into contractor agreements with third parties who own and operate tractors (or hire their own driving associates to operate the tractors) that service our customers. We pay these independent contractors for their services, based on a contracted rate per mile. By operating safely and productively, independent contractors can improve their own profitability and ours. Independent contractors are responsible for most costs incurred for owning and operating their tractors. In 2020, independent contractors comprised 10.9% of our total fleet, as measured by average tractor count.

Safety and Insurance

Safety

We are committed to safe and secure operations. We conduct an intensive driver qualification process, including defensive driving training. We require prospective drivers to meet higher qualification standards than those required by the DOT, including extensive background checks and hair follicle drug testing. We regularly communicate with drivers to promote safety and instill safe work habits through effective use of various media and safety review sessions. We dedicate personnel and resources designed to ensure safe operation and regulatory compliance. We employ technology to assist us in managing risks associated with our business. We have event recorders in all of our tractors, which are used daily by drivers and operations leaders to provide feedback and coaching in regard to driving behaviors. In addition, we have an innovative recognition program for driver safety performance and emphasize safety through our equipment specifications and maintenance programs. Our Corporate Directors of Safety review all accidents and report weekly to leadership.

Insurance

The primary claims arising in our business consist of auto liability, including personal injury, property damage, physical damage, and cargo loss. We self-insure for a significant portion of our claims exposure and related expenses. We also maintain insurance that covers our directors and officers for losses and expenses arising out of claims, based on acts or omissions in their capacities as directors or officers. While under dispatch and our operating authority, the independent contractors we contract with are covered by our liability coverage and self-insurance retention limits. However, each is responsible for physical damage to his or her own equipment, occupational accident coverage, and liability exposure while the truck is used for non-company purposes. Additionally, fleet operators are responsible for any applicable workers' compensation requirements for their employees.

We insure certain casualty risks through our wholly-owned captive insurance subsidiaries, Mohave and Red Rock. Mohave and Red Rock provide reinsurance associated with a share of our automobile liability risk. In addition to insuring a proportionate share of our corporate casualty risk, Mohave provides reinsurance coverage to third-party insurance companies associated with our affiliated companies' independent contractors.

Please refer to Note 13 in Part II, Item 8 of this Annual Report for more information about our insurance policies and self-insurance retention limits.

Fuel

We actively manage our fuel purchasing network in an effort to maintain adequate fuel supplies and reduce our fuel costs. Additionally, we utilize a fuel surcharge program to pass a majority of increases in fuel costs to our customers. In 2020, we purchased 12.3% of our fuel in bulk at our Swift, Knight, and dedicated customer locations across the US and Mexico. We purchased substantially all of the remainder through a network of retail truck stops with which we have negotiated volume purchasing discounts. The volumes we purchase at terminals and through the fuel network vary based on procurement costs and other factors. We seek to reduce our fuel costs by routing our driving associates to truck stops when fuel prices at such stops are cheaper than the bulk rate paid for fuel at our terminals. We primarily store fuel in above-ground storage tanks at most of our other bulk fueling terminals. We believe that we are sufficiently in compliance with applicable environmental laws and regulations relating to the storage and dispensing of fuel.

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

Seasonality

See Note 1 in Part II, Item 8 in this Annual Report, regarding the impact of seasonality on our operations.

Environmental Regulation

General

We have bulk fuel storage and fuel islands at many of our terminals, as well as vehicle maintenance, repair, and washing operations at some of our facilities, which exposes us to certain environmental risks. Soil and groundwater contamination have occurred at some of our facilities in prior years, for which we have been responsible for remediating the environmental contamination. Also, a small percentage of our total shipments contain hazardous materials, which are generally rated as low to medium-risk, and subject us to a wide array of regulation. In the past, we have been responsible for the costs of clean-up of cargo and diesel fuel spills caused by traffic accidents or other events.

We have instituted programs to monitor and mitigate environmental risks and maintain compliance with applicable environmental laws governing the hauling, handling, and disposal of hazardous materials, fuel spillage or seepage, emissions from our vehicles and facilities, engine-idling, discharge and retention of storm water, and other environmental matters. As part of our safety and risk management program, we periodically perform internal environmental reviews. We are a Charter Partner in the EPA's SmartWay Transport Partnership, a voluntary program promoting energy efficiency and air quality. We believe that our operations are in material compliance with current laws and regulations and do not know of any existing environmental condition that would reasonably be expected to have a material adverse effect on our business or operating results.

If we are held responsible for the cleanup of any environmental incidents or conditions caused by our operations or business, or if we are found to be in violation of applicable laws or regulations, we could be subject to clean-up costs and other liabilities, including substantial fines, penalties and/or civil and criminal liability, any of which could have a material, adverse effect on our business and results of operations. We have paid penalties for spills and violations in the past; however, they have not been material to our financial results or position.

Greenhouse Gas ("GHG") Emissions and Fuel Efficiency Standards

California ARB — In 2008, the State of California's Air Resources Board ("ARB") approved the Heavy-Duty Vehicle GHG Emission Reduction Regulation in efforts to reduce GHG emissions from certain long-haul tractor-trailers that operate in California by requiring them to utilize technologies that improve fuel efficiency (regardless of where the vehicle is registered). The regulation, which became effective in 2010, required owners of long-haul tractors and 53-foot trailers to be EPA SmartWay certified or replace or retrofit their vehicles with aerodynamic technologies and low-rolling resistance tires. The regulation also contained certain emissions and registration standards for refrigerated trailers.

In February 2018, California's ARB approved California Phase 2 standards that generally align with the federal Phase 2 standards, with some minor additional requirements, and which would stay in place even if the federal Phase 2 standards are affected by action from President Trump's administration. In February 2019, the California Phase 2 standards became final.

In June 2020, ARB passed the Advanced Clean Trucks (“ACT”) regulation, requiring original equipment manufacturers to begin shifting towards greater production of zero-emission heavy duty tractors starting in 2024. Under ACT, by 2045, every new tractor sold in California will need to be zero-emission. While ACT does not apply to those simply operating tractors in California, it could affect the cost and/or supply of traditional diesel tractors and may lead to similar legislation in other states or at the federal level.

EPA and NHTSA — The EPA and the National Highway Traffic Safety Administration ("NHTSA") have begun taking coordinated steps in support of a new generation of clean vehicles and engines through reduced GHG emissions and improved fuel efficiency at a national level. In September 2011, the EPA finalized the Phase 1 federal regulations for controlling GHG emissions, related to efficient engines, use of auxiliary power units, mass reduction, low-rolling resistance tires, improved aerodynamics, improved transmissions, and reduced accessory loads.

•Phase 2 —In August 2016, the EPA and NHTSA announced the final rule regarding Phase 2, which builds upon Phase 1, and would apply to certain trailer types beginning with model-year 2018 for EPA standards (voluntary for NHTSA standards through model-year 2020). Tractors and certain trailer types would be subject to the Phase 2 standards beginning with model-year 2021, increasing in stringency through model-year 2024, and phasing in completely by model-year 2027. This rule marks the first time federal mandates will be applied to trailers, with respect to aerodynamics and low-rolling resistance tires. The final rule was effective in December 2016.

Additionally, implementation of the Phase 2 standards as they relate to trailers has been delayed due to a provisional stay granted in October 2017 by the US Court of Appeals for the District of Columbia, which is overseeing a case against the EPA by the Truck Trailer Manufacturers Association, Inc. regarding the Phase 2 standards. If the glider provisions are removed from the Phase 2 standards as the EPA has proposed in the past, there would be no direct effect on our results of operations. If the trailer provisions of the Phase 2 standards are permanently removed, we would still need to ensure the majority of our fleet is compliant with the California Phase 2 standards.

In January 2020, the EPA announced it is seeking input on reducing emissions of nitrogen oxides and other pollutants from heavy-duty trucks. The EPA is aiming to release proposed rulemaking for the new plan, commonly referred to as the “Cleaner Trucks Initiative,” in 2021. The EPA is targeting 2027 for these new standards to take effect.

Complying with these and any future GHG regulations enacted by California’s ARB, the EPA, the NHTSA and/or any other state or federal governing body has increased and will likely continue to increase the cost of our new tractors, may increase the cost of new trailers, may require us to retrofit certain of our trailers, may increase our maintenance costs, and could impair equipment productivity and increase our operating costs, particularly if such costs are not offset by potential fuel savings. These adverse effects, combined with the uncertainty as to the reliability of the newly designed diesel engines and the residual values of our equipment, could materially increase our costs or otherwise adversely affect our business or operations. We cannot predict, however, the extent to which our operations and productivity will be impacted. We will continue monitoring our compliance with federal and state GHG regulations.

Climate-change Proposals

Federal and state lawmakers are considering a variety of other climate-change proposals related to carbon emissions and GHG emissions. The proposals could potentially limit carbon emissions within certain states and municipalities, which continue to restrict the location and amount of time that diesel-powered tractors (like ours) may idle.

These restrictions could force us to purchase on-board power units that do not require the engine to idle or to alter our driving associates' behavior, which could result in a decrease in productivity, or increase in driving associate turnover.

Industry Regulation

Our operations are regulated and licensed by various federal, state, and local government agencies in North America, including the DOT, the FMCSA, and the US Department of Homeland Security, among others. Our company, as well as our driving associates and independent contractors, must comply with enacted governmental regulations regarding safety, equipment, and operating methods. Examples include regulation of equipment weight, equipment dimensions, driver hours-of-service, driver eligibility requirements, on-board reporting of operations, and ergonomics. The following discussion presents recently enacted federal, state, and local regulations that could have an impact on our operations.

Moving Ahead for Progress in the 21st Century Bill

In July 2012, Congress passed the Moving Ahead for Progress in the 21st Century bill into law. Included in the highway bill was a provision that mandates electronic logging devices in commercial motor vehicles to record hours-of-service. Additionally, in response to the bill, a final rule related to entry-level driver training was passed in 2016, as well as amendments to the Drug and Alcohol Clearinghouse rules.

ELD — During 2012, the FMCSA published a Supplemental NPRM, announcing its plan to proceed with the ELDs and hours-of-service supporting documents rulemaking. The ELD rule became final in December 2015, as published in the Federal Register, with an effective date in February 2016. The ELD rule phased in over a four-year period, with all drivers and carriers subject to the rule being required to use certified and registered ELDs that comply with the requirements of the ELD regulations by December 16, 2019.

Although the final ELD rule may have caused many carriers to experience at least a short-term drop in production and has had a significant impact on the industry as a whole, we have not experienced any adverse effects, as we had installed ELDs in our operational trucks well before the requisite compliance dates in conjunction with our efforts to improve efficiency and communications with driving associates and independent contractors. However, we believe that more effective hours-of-service enforcement under the ELD rule may improve our competitive position by causing all carriers to adhere more closely to hours-of-service requirements.

Commercial Driver's License Drug and Alcohol Clearinghouse — In December 2016, the FMCSA amended the Federal Motor Carrier Safety Regulations to establish requirements of the Commercial Driver's License Drug and Alcohol Clearinghouse, a database under its administration containing information about violations of the FMCSA's drug and alcohol testing program for holders of commercial driver's licenses. The final rule became effective in January 2017, with a compliance date in January 2020. In December 2019, however, the FMCSA announced a final rule extending by three years the date for state driver’s licensing agencies to comply with certain requirements. The December 2016 commercial driver’s license rule required states to request information from the Clearinghouse about individuals prior to issuing, renewing, upgrading or transferring a commercial driver's license. This new action will allow states’ compliance with the requirement, which was set to begin January 2020, to be delayed until January 2023. The compliance date of January 2020 remained in place for all other requirements set forth in the Clearinghouse final rule, however. Upon implementation, the rule may reduce the number of available drivers in an already constrained driver market.

In September 2020, the Department of Health and Human Services (“DHHS”) announced proposed mandatory guidelines to allow employers to drug test truck drivers and other federal workers for pre-employment and random testing using hair specimens. However, the proposal also requires a second sample using either urine or an oral swab test if a hair test is positive, if a donor is unable to provide a sufficient amount of hair for faith-based or medical reasons, or due to an insufficient amount or length of hair. DHHS indicated the two-test approach is intended to protect federal workers from issues that have been identified as limitations of hair testing, and related legal deficiencies identified in prior court cases. The American Trucking Associations (“ATA”) has voiced concerns with the new guidelines, taking particular issue with the second sample requirement, which the ATA feels diminishes the value of hair testing. It is unclear if and when a final rule may be put in place. Any final rule may reduce the number of available drivers. We currently perform hair follicle testing and will continue to monitor any developments in this area to ensure compliance.

Entry-Level Driver Training — In December 2016, the FMCSA established new minimum training standards for certain individuals applying for (or upgrading) a Class A or Class B commercial driver's license, or obtaining a hazardous materials, passenger, or school bus endorsement on their commercial driver's license for the first time. Such individuals are subject to the entry-level driver training requirements and must complete a prescribed program of theory and behind-the-wheel instruction. The final rule requires that behind-the-wheel proficiency of an entry-level truck driver be determined solely by the instructor's evaluation of how well the driver-trainee performs the fundamental vehicle controls skills and driving procedures set forth in the curricula, but does not have a minimum training hours requirement, as proposed by the FMCSA earlier in 2016. The final rule went into effect in February 2017, with an initial compliance date in February 2020. However, in May 2020, the FMCSA approved an interim rule delaying implementation of the final rule by two years, extending the compliance date to February 2022. Upon the compliance date, training schools will be required to register with the FMCSA's Training Provider Registry and certify that their program meets the classroom and driving standards. We will also be required to comply with this rule in the course of operating our driving schools. The effect of this rule could result in a decrease in fleet production and driver availability, either of which could adversely affect our business or operations. US Congressional representatives also proposed a bill in 2019 that would pave the way for commercial drivers younger than 21 to drive tractors across state lines. This bill, which would lower the age requirement of 21 to 18 for interstate commercial driving if certain requirements are met, received support from the ATA during a February 2020 Senate hearing. It is unclear how long the process of finalizing such a bill will take, however if one comes to fruition at all. Meanwhile, the FMCSA announced in September 2020 that it is proposing and seeking public comments on a new pilot program to allow drivers aged 18, 19, and 20 to operate commercial motor vehicles in interstate commerce.

Hours-of-service

From time to time, the FMCSA proposes and implements changes to regulations impacting hours-of-service. Such changes can negatively impact our productivity and affect our operations and profitability by reducing the number of hours per day or week our driving associates and independent contractors may operate and/or disrupting our network. No such changes are currently proposed. However, in August 2019, the FMCSA issued a proposal to make changes to its hours-of-service rules that would allow truck drivers more flexibility with their 30-minute rest break and with dividing their time in the sleeper berth. It also would extend by two hours the duty time for drivers encountering adverse weather and extend the shorthaul exemption by lengthening the drivers’ maximum on-duty period from 12 hours to 14 hours. In June 2020 the FMCSA adopted a final rule substantially as proposed, which became effective September 2020. Any future changes to hours-of-service regulations could materially and adversely affect our operations and profitability.

Safety and Fitness Ratings

There are currently two methods of evaluating the safety and fitness of carriers: CSA, which evaluates and ranks fleets on certain safety-related standards by analyzing data from recent safety events and investigation results, and the DOT safety rating, which is based on an on-site investigation and affects a carrier's ability to operate in interstate commerce. Additionally, the FMCSA has proposed rules in the past that would change the methodologies used to determine carrier safety and fitness.

DOT Safety Rating — The DOT safety rating is currently the only safety measurement system that has a direct impact on a carrier's ability to operate in interstate commerce. Both Knight and Swift currently have a satisfactory DOT safety rating, which is the best available rating under the current safety rating scale. If we were to receive a conditional or unsatisfactory DOT safety rating, it could adversely affect our business, as some of our existing customer contracts require a satisfactory DOT safety rating.

CSA — In December 2010, the FMCSA introduced CSA, an enforcement and compliance model that ranks on seven categories of safety-related data. The seven categories of safety-related data, currently include Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator, (such categories known as "BASICs"). Carriers are grouped by category with other carriers that have a similar number of safety events (i.e. crashes, inspections, or violations) and carriers are ranked and assigned a rating percentile or score to prioritize them for interventions if they are above a certain threshold.

Certain CSA scores were initially published and made available to the general public. However, in December 2015, as part of the Fixing America's Surface Transportation ("FAST") Act, Congress mandated that the FMCSA remove all CSA scores from public view until a more comprehensive study regarding the effectiveness of CSA improving

16

truck safety could be completed. Although the FMCSA has since provided a report to Congress outlining the changes it may make to the CSA program, it remains unclear if, when, and to what extent any such changes will occur. However, any changes that increase the likelihood of us receiving unfavorable scores could adversely affect our results of operations and profitability.

In May 2020 the FMCSA announced that effective immediately it is making permanent a pilot program that will not count a crash in which a motor carrier was not at fault when calculating the carrier’s safety measurement profile, called the Crash Preventability Demonstration Program (“CPDP”). The CPDP will expand the types of eligible crashes, modify the Safety Measurement System to exclude crashes with not preventable determinations from the prioritization algorithm and note the not preventable determinations in the Pre-Employment Screening Program.

CSA scores do not currently have a direct impact on a carrier's safety rating. However, the occurrence of unfavorable scores in one or more categories may affect driving associate recruiting and retention by causing qualified driving associates to seek employment with other carriers, cause our customers to direct their business away from us and to carriers with more favorable scores, subjecting us to an increase in compliance reviews and roadside inspections, or cause us to incur greater than expected expenses in our attempts to improve unfavorable scores, any of which could adversely affect our results of operations and profitability.

Safety Fitness Determination —In January 2016, the FMCSA published a Notice of Proposed Rulemaking ("NPRM") in the Federal Register, regarding carrier safety fitness determination. The NPRM proposed new methodologies that would have determined when a motor carrier was not fit to operate a commercial motor vehicle. Based on public feedback and other concerns raised by industry stakeholders, in March 2017, the FMCSA withdrew the NPRM related to the new safety rating system. In its notice of withdrawal, the FMCSA noted that a new rulemaking related to a similar process may be initiated in the future. Therefore, it is uncertain if, when, or under what form any such rule could be implemented. The FMCSA also recently indicated its intent to perform a new study on the causation of crashes. Although it remains unclear whether such a study will ultimately be undertaken and completed, the results of such a study could spur further proposed and/or final rules in regards to safety and fitness.

Prohibiting Coercion of Commercial Motor Vehicle Drivers

In November 2015, the Prohibiting Coercion of Commercial Motor Vehicle Drivers rule became final. The rule explicitly prohibits motor carriers from coercing drivers to violate certain FMCSA regulations, including driver hours-of-service limits, Commercial Drivers' License regulations, drug and alcohol testing rules, and hazardous materials regulations, among others. Under the rule, drivers can report incidents of coercion to the FMCSA, who is authorized to issue penalties against the motor carrier. We have not experienced any significant impacts from this rule.

Speed Limiting Devices

In June 2019, legislation was introduced that would require all new commercial trucks with a gross weight of 26,001 pounds or more to be equipped with speed-limiting devices, which must be set to a maximum speed of 65 miles per hour and be used at all times while in operation. The maximum speed requirement would also be extended to existing trucks that already have the technology installed. Whether this legislation will ultimately become law is uncertain. While we currently govern the speed of our company tractors below these limits, such legislation could result in a decrease in fleet production and driver availability, either of which could adversely affect our business or operations.

For safety, we electronically govern the speed of substantially all of our company tractors. Additionally, our independent contractor agreements include statements that independent contractors must comply with the Company's speed policy.

Food Safety Modernization Act of 2011 ("FSMA")

In April 2016, the Food and Drug Administration ("FDA") published a final rule establishing requirements for shippers, loaders, carriers by motor vehicle and rail vehicle, and receivers engaged in the transportation of food, to use sanitary transportation practices to ensure the safety of the food they transport as part of the FSMA. This rule sets forth requirements related to among other things, equipment used to transport food, measures taken during such transportation, personnel training, and record retention. These requirements took effect for larger carriers such as us in April 2017 and are also applicable when we perform as a carrier or as a broker. We believe we have been in compliance with these requirements since that time. However, if we are found to be in violation of applicable laws or regulations related to the FSMA, or if we transport food or goods that are contaminated or are found to cause illness and/or death, we could be subject to substantial fines, lawsuits, penalties and/or criminal and civil liability, any of which could have a material adverse effect on our business, financial condition, and results of operations.

As the FDA continues its efforts to modernize food safety, it is likely additional food safety regulations will take effect in the future. In July 2020, the FDA released its “New Era of Smarter Food Safety” blueprint, which creates a ten year roadmap to create a more digital, traceable and safer food system. This blueprint builds on the work done under the FSMA, and while it is still unclear what, if any, changes to the current governing framework may ultimately take effect, further regulation in this area could negatively affect our business by increasing our compliance obligations and related expenses going forward.

Legislation Regarding Independent Contractors

Tax and other regulatory authorities have sought in the past to assert that independent contractors in the trucking industry are employees rather than independent contractors. Federal legislators continue to introduce legislation concerning the classification of independent contractors as employees, including legislation that proposes to increase the tax and labor penalties against employers who intentionally or unintentionally misclassify employees as independent contractors and are found to have violated employees' overtime or wage requirements. Additionally, federal legislators have sought to:

•abolish the current safe harbor allowing taxpayers meeting certain criteria to treat individuals as independent contractors if they are following a long-standing, recognized practice,

•extend the FLSA to independent contractors, and

•impose notice requirements based upon employment or independent contractor status and fines for failure to comply.

Some states have adopted initiatives to increase their revenues from items such as unemployment, workers' compensation, and income taxes, and we believe a reclassification of independent contractors as employees would help states with this initiative. Federal and state taxing and other regulatory authorities and courts apply a variety of standards in their determination of independent contractor status.

Recently, courts in certain states have issued decisions that could result in a greater likelihood that independent contractors would be judicially classified as employees in such states. Further, class actions and other lawsuits have been filed against us and other members of our industry seeking to reclassify independent contractors as employees for a variety of purposes, including workers' compensation and health care coverage. Our defense of such class actions and other lawsuits has not always been successful, and we have been subject to adverse judgments with respect to such matters. In addition, 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. If our independent contractors were determined to be our employees, we would incur additional exposure under federal and state tax, workers' compensation, unemployment benefits, labor, employment, and tort laws, which could potentially include prior periods, as well as potential liability for employee benefits and tax withholdings. We currently observe and monitor our compliance with current related and applicable laws and regulations, but we cannot predict whether future laws and regulations, judicial decisions, or settlements regarding the classification of independent contractors will adversely affect our business or operations.

In September 2019, California enacted A.B. 5 ("AB5"), a new law that changed the landscape of the state’s treatment of employees and independent contractors. AB5 provides that the three-pronged "ABC Test" must be used to determine worker classification in wage-order claims. Under the ABC Test, a worker is presumed to be an employee and the burden to demonstrate their independent contractor status is on the hiring company through satisfying all three of the following criteria:

18

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

•the worker is free from control and direction in the performance of services;

•the worker is performing work outside the usual course of the business of the hiring company;

•the worker is customarily engaged in an independently established trade, occupation, or business.

How AB5 will be enforced is still to be determined. In January 2021, however, the California Supreme Court ruled that the ABC Test could apply retroactively to all cases not yet final as of the date the original decision was rendered, April 30, 2018. While it was set to go into effect in January 2020, a federal judge in California issued a preliminary injunction barring the enforcement of AB5 on the trucking industry while the California Trucking Association ("CTA") moves forward with its suit seeking to invalidate AB5. While this preliminary injunction provides temporary relief to the enforcement of AB5, it remains unclear how long such relief will last, and whether the CTA will ultimately be successful in invalidating the law. It is also possible AB5 will spur similar legislation in states other than California, which could adversely affect our results of operations and profitability. In September 2020, the US Court of Appeals for the Ninth Circuit heard oral arguments in the case to decide whether the preliminary injunction prohibiting the state from enforcing the ABC Test against motor carriers should remain in effect. A decision on the matter is expected soon. Meanwhile, in November 2020, a California state appeals court ruled that the Federal Aviation Administration Authorization Act (“FAAAA”) does not preempt application of the ABC Test to truck drivers. Because this opinion came from a California state court, however, it does not directly impact the Ninth Circuit decision discussed above.

State Wage and Hour Legislation

In December 2018, the FMCSA granted a petition filed by the American Trucking Associations and in doing so determined that federal law does preempt California’s wage and hour laws, and interstate truck drivers are not subject to such laws. The FMCSA’s decision has been appealed by labor groups and multiple lawsuits have been filed in federal courts seeking to overturn the decision, and while the Ninth Circuit Court of Appeals has since upheld the FMCSA’s decision, it still remains uncertain whether it will stand. Other current and future state and local wage and hour laws, including laws related to employee meal breaks and rest periods, may also vary significantly from federal law. Further, driver piece rate compensation, which is an industry standard, has been attacked as non-compliant with state minimum wage laws. Both of these issues are adversely impacting the Company and the industry as a whole, with respect to the practical application of the laws, thereby resulting in additional cost. As a result, we are subject to an uneven patchwork of wage and hour laws throughout the US. If federal legislation is not passed preempting state and local wage and hour laws, we will either need to comply with the most restrictive state and local laws across our entire fleet, or revise our management systems to comply with varying state and local laws. Either solution could result in increased compliance costs, increased driver turnover, decreased efficiency, and amplified legal exposure.

Other Regulation

Executive Order

It is still to be determined how President Biden’s leadership will impact our industry. That being said, President Biden has indicated his intent to make a green infrastructure package a top priority for his administration. Any measure in furtherance thereof could draw from the Moving Forward Act, a $1.5 trillion infrastructure bill that passed the US House of Representatives in June 2020, but is still waiting to be heard by the US Senate. The Moving Forward Act incorporated and expanded upon the Investing in a New Vision for the Environment and Surface Transportation in America (INVEST in America) Act, a nearly $500 billion bill intended to rebuild and reimagine US transportation and infrastructure that was passed out of the House Committee on Transportation and Infrastructure in June 2020. It is unclear whether these legislative initiatives will be signed into law and what changes they may undergo prior thereto. However, adoption and implementation of the same could negatively impact our business by increasing our compliance obligations and related expenses.

The Tax Cuts and Jobs Act

In December 2017, the US enacted significant changes to its tax law following the passage and signing of H.R.1, "An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018" (previously known as "The Tax Cuts and Jobs Act"). The longevity of the Tax Cuts and Jobs Act remains unclear, however, with President Biden indicating an intention to make substantial changes to the current US tax structure during his administration, including changes to the way capital gains are treated. Any changes to US tax laws may have an adverse impact on our business and profitability.

US-Mexico-Canada Agreement

The US-Mexico-Canada Agreement ("USMCA") was entered into effect in July 2020. The USMCA is designed to modernize food and agriculture trade, advance rules of origin for automobiles and trucks, and enhance intellectual property protections, among other matters, according to the Office of the US Trade Representative. It is difficult to predict at this stage what could be the impact of the USMCA on the economy, including the transportation industry. However, given the amount of North American trade that moves by truck, it could have a significant impact on supply and demand in the transportation industry, and could adversely impact the amount, movement, and patterns of freight we transport.

FAST Act

With the FAST Act originally scheduled to expire in September 2020, Congress had noted its intent to consider a multiyear highway measure that would update the FAST Act. However, in September 2020 Congress approved a one year extension of the FAST Act, now set to expire in September 2021. If Congress fails to reauthorize the FAST Act or pass updated replacement legislation by the September 2021 deadline and proceeds to manage transportation policy via short-term legislative directives, there will be uncertainty that could have a negative impact on our operations.

COVID-19

Given COVID-19’s considerable effect on the transportation industry in 2020, the FMCSA issued various temporary responsive measures throughout the year in order to combat the same, including, without limitation, those related to hours of service, commercial driver’s licenses, and medical certifications. Although, to date, these measures have largely been enacted in order to assist industry participants in operating under adverse circumstances, any further responsive measures remain unclear and could have a negative impact on our operations.

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 *Employees *Environmental Regulation *Debt

*Mergers and Acquisitions *Vendors and Suppliers *Goodwill and Intangibles

*International Operations *Customers

*Information Systems

Strategic Risk

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

The truckload industry is 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.

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 a experience a reduction in overall freight levels and freight patterns may change as supply chains are redesigned, resulting an imbalance between our capacity and our customers’ freight demands.

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 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.

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;

•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 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 truckload operations. We have experienced an increase in prices for new tractors over the past few years, and the resale value of the tractors 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. We expect to continue to pay increased prices for equipment and incur additional expenses for the foreseeable future.

Furthermore, a decrease in vendor output may have a materially adverse effect on our ability to purchase a quantity of new revenue equipment that is sufficient to sustain our desired growth rate and to maintain a late-model fleet.

We have certain revenue equipment leases and financing arrangements with balloon payments at the end of the lease term equal 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 equal to the excess of the balloon payment owed to the lease or finance company over 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 used equipment, the availability 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.

If fuel prices increase significantly, our results of operations could be adversely affected.

Our truckload operations are dependent upon diesel fuel, and accordingly, significant increases in diesel fuel costs 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.

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. Additionally, a shortage or rationing of diesel fuel, could materially and adversely affect our results of operations.

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

We have growing operations in Mexico, through our wholly-owned subsidiary, Trans-Mex, which subjects us to general international business risks, including:

•foreign currency fluctuation;

•changes in Mexico's economic strength;

•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 and US-Mexico relations;

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

•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 were 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. In addition, acquisitions 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;

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

•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. Furthermore, there is no assurance that our operating margins will not be adversely affected by future changes in and expansion of our business or by changes in economic conditions or that we will be able to sustain or improve our profitability in the future.

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

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

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

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

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

•we may be unable to recruit and retain qualified personnel and management with requisite experience or knowledge of our logistics services, and other 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 or 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. 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.

23

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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.

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 as intermodal services expand. 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, which could increase the cost of the rail-based services we provide and could reduce the reliability, timeliness, efficiency, and overall attractiveness of our rail-based intermodal services. 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 capacity providers. These third-party providers may seek other freight opportunities and may require increased compensation in times of improved freight demand or tight truckload 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 13 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 other 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 a portion of our risk through our captive insurance companies, Mohave and Red Rock. In addition to insuring portions of our own risk, Mohave provides reinsurance coverage to third-party insurance companies associated with our affiliated companies' independent contractors. Red Rock insures a share of our automobile liability risk. The insurance and reinsurance markets are subject to market pressures. Our captive insurance companies' abilities or needs to access the reinsurance markets may involve the retention of additional risk, which could expose us to volatility in claims expenses.

24

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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 trucking 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.

Increases in driving associate compensation or difficulties attracting and retaining qualified driving associates 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 transportation industry is 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 COVID-19-related social distancing requirements. Regulatory requirements could further reduce the number of eligible driving associates. We believe our employee screening process, which includes extensive 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. 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.

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.

Our 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.

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, 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. 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

25

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

natural disaster, fire, power loss, telecommunications failure, cyber-attacks, terrorist attacks, internet failures, and other events beyond our control. 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.

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.

Seasonality and the impact of weather and other catastrophic events could have a materially adverse effect on our results of operations and profitability or make our results of operations and profitability more volatile.

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

Our business and results of operations have been and will be, and our financial condition may be, impacted by the outbreak of COVID-19 or other similar outbreaks, and such impact could be materially adverse, during the pandemic or after the pandemic subsides.

The global spread of COVID-19 has created, and any other outbreaks of similar contagious diseases or other adverse public health developments could create, significant volatility, uncertainty and economic disruption. We have experienced an increase in absences among our driver and non-driver personnel due to the outbreak of COVID-19. Further, our operations, particularly in areas of increased COVID-19 infections could be disrupted. Negative financial results, operational disruptions, driver and non-driver absences, uncertainties in the market, and a tightening of credit markets, caused by COVID-19, other similar outbreaks, or a recession, could have a material adverse effect on our liquidity, reduce credit options available to us, and adversely impact our ability to effectively meet our short- and long-term obligations.

The COVID-19 outbreak has caused uncertainty in the economy. Risks related to an economic slowdown or recession are described in our risk factor titled "Our business is subject to economic, credit, business, and regulatory factors affecting the truckload industry that are largely beyond our control, any of which could have a materially adverse effect on our results of operations."

Developments related to COVID-19 have been unpredictable and the extent to which further developments could impact our operations, financial condition, liquidity, results of operations, and cash flows is highly uncertain. Such developments may include the duration of the virus, the distribution and availability of vaccines, the severity of the disease, and the actions that may be taken by various governmental authorities and other third parties in response to the pandemic.

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 the DOT, the EPA, the DHS, and other state and federal 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" in Part I, Item 1 of this Annual Report, discusses in detail industry regulations 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 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.

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, then we fail to comply with such laws and 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 truckload operations are affected by laws and regulations related to air emissions and fuel efficiency. "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, Trans-Mex, we always face the risk that our employees will try to unionize. If we entered into a collective bargaining agreement with our domestic employees, the terms could materially adversely affect our costs, efficiency, and ability to generate acceptable returns on the affected operations. 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

27

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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. 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.

Our business is subject to the risk of litigation. 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. The cost to defend litigation may also be significant. Not all claims are covered by our insurance, and there can be no assurance that our coverage limits will be adequate to cover all amounts in dispute. To the extent we experience claims that are uninsured, exceed our coverage limits, 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.

In addition, we may be subject, and have been subject in the past, to litigation resulting from trucking accidents. The number and severity of litigation claims may be worsened by distracted driving by both truck drivers and other motorists. These lawsuits have resulted, and may result in the future, in the payment of substantial settlements or damages and increases of our insurance costs.

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.

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

28

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

Financial Risk

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

Our truckload 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 truckload operations may have too many or too few assets. 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.

Credit markets may weaken at some point in the future, which would make it difficult for us to access our current sources of credit and 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.

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;

•increased interest rates that would affect our variable rate debt;

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

29

Table of ContentsGlossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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

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

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

As detailed in Note 16 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 the 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.

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. 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.

PART II

Common Stock

Our common stock trades on the NYSE under the symbol "KNX". Prior to the completion of the 2017 Merger, shares of Swift Class A common stock traded on the NYSE under the symbol "SWFT" while shares of Knight common stock traded on the NYSE under the symbol "KNX."

Common Stock — As of December 31, 2020, we had 166,552,762 shares of common stock outstanding. On February 16, 2021, there were 41 holders of record of our common stock. Because many of our shares of common stock are held by brokers or other institutions on behalf of stockholders, we are unable to estimate the total number of individual stockholders represented by the record holders.

Dividend Policy

We have paid a quarterly cash dividend as Knight-Swift since December 27, 2017, consistent with Knight's historical practice that started in December 2004, and that continued in consecutive quarters since prior to the 2017 Merger.

Our most recent dividend was declared in February of 2021 for $0.08 per share of common stock and is scheduled to be paid in March of 2021.

We currently expect to continue to pay comparable quarterly cash dividends in the future. Future payment of cash dividends, and the amount of any such dividends, will depend upon our financial condition, results of operations, cash requirements, tax treatment, and certain corporate law requirements, as well as other factors deemed relevant by our Board.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

2017 Merger —On September 8, 2017, we became Knight-Swift Transportation Holdings Inc. upon the effectiveness of the 2017 Merger. Immediately upon the consummation of the 2017 Merger, former Knight stockholders and former Swift stockholders owned approximately 46.0% and 54.0%, respectively, of the Company.

Our shares of Class A common stock commenced trading on the NYSE on a post-reverse split basis under the ticker symbol "KNX" on September 11, 2017.

Acquisitions — On January 1, 2020, the Company acquired a warehousing company to complement its suite of services. Please refer to Note 5 in Part II, Item 8 of this Annual Report.

Revenue

•Our trucking services include irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border transportation of various products, goods, and materials for our diverse customer base. We primarily generate revenue by transporting freight for our customers through our Trucking segment.

•Our brokerage and intermodal operations 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. Revenue in our brokerage and intermodal operations is generated through our Logistics and Intermodal segments.

•Our non-reportable segments include support services provided to our customers and independent contractors (including repair and maintenance shop services, equipment leasing, warranty services, and insurance), trailer parts manufacturing, warehousing, and certain driving academy activities, as well as certain corporate expenses (such as legal settlements and accruals, certain impairments, and amortization of intangibles related to the 2017 Merger and certain 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 program, which serves to recover a majority of our fuel costs. This applies only to loaded miles and typically does not offset non-

paid empty miles, idle time, and 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 Trucking segment.

Expenses —Our most significant expenses vary with miles traveled and include fuel, driving associate-related expenses (such as wages and benefits), and services purchased from independent contractors and other transportation providers (such as railroads, drayage providers, and other trucking companies). 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 improvements, fleet age, efficiency, and other factors. Our primary fixed costs are depreciation and lease expense for revenue equipment and terminals, amortization of intangibles, interest expense, and non-driver employee compensation.

Operating Statistics — We measure our consolidated and segment results through certain operating statistics, which are discussed under "Results of Operations — Segment Review — Operating Statistics," below.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 16 headings are on that chain and 15 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
