KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 — Introduction and Basis of Presentation

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

Description of Business

Knight-Swift is a transportation solutions provider, headquartered in Phoenix, Arizona. During the first half of 2021, the Company operated an average of 18,129 tractors (comprised of 16,225 company tractors and 1,904 independent contractor tractors) and 60,382 trailers within the Trucking segment. Additionally, the Company operated an average of 605 tractors and 10,844 containers in the Intermodal segment. As of June 30, 2021, the Company's three reportable segments are Trucking, Logistics, and Intermodal.

Basis of Presentation

The condensed consolidated financial statements and footnotes included in this Quarterly Report include the accounts of Knight-Swift Transportation Holdings Inc. and its subsidiaries and should be read in conjunction with the consolidated financial statements and footnotes included in Knight-Swift's 2020 Annual Report. In management's opinion, these condensed consolidated financial statements were prepared in accordance with GAAP and include all adjustments necessary (consisting of normal recurring adjustments) for the fair statement of the periods presented.

With respect to transactional/durational data, references to years pertain to calendar years. Similarly, references to quarters pertain to calendar quarters.

Seasonality

In the transportation industry, results of operations generally follow a seasonal pattern. Freight volumes in the first quarter are typically lower due to less consumer demand, customers reducing shipments following the holiday season, and inclement weather. At the same time, operating expenses generally increase, and tractor productivity of the Company's fleet, independent contractors, and third-party carriers decreases during the winter months due to decreased fuel efficiency, increased cold weather-related equipment maintenance and repairs, and increased insurance claims and costs attributed to higher accident frequency from harsh weather. These factors typically lead to lower operating profitability, as compared to other parts of the year. Additionally, beginning in the latter half of the third quarter and continuing into the fourth quarter, the Company typically experiences surges pertaining to holiday shopping trends toward delivery of gifts purchased over the Internet, as well as the length of the holiday season (consumer shopping days between Thanksgiving and Christmas). However, cyclical changes in the trucking industry, including imbalances in supply and demand, can override the seasonality faced in the industry.

Impact of COVID-19

The Company continues to operate its business through the COVID-19 pandemic, including recent variants, and has taken additional precautions to ensure the safety of its employees, customers, vendors, and the communities in which it operates.

There are various uncertainties that have arisen from the COVID-19 pandemic. While management is continuing to monitor the impact of the pandemic on Knight-Swift, including its employees, customers, independent contractors, stockholders, and other business partners and stakeholders, it is difficult to predict the impact that the pandemic will have on future results of its operations, financial position, and liquidity. This has caused some uncertainties around various accounting estimates. Due to these uncertainties, the Company's accounting estimates may change, as management's assessment of the impacts of the COVID-19 pandemic continues to evolve.

Note 2 — Recently Issued Accounting Pronouncements

There have been no ASUs issued since the filing date of the 2020 annual report that may have a material impact on the Company.

Note 3 — Acquisitions

AAA Cooper Transportation Acquisition

On July 5, 2021, the Company acquired 100% of Dothan, Alabama-based AAA Cooper Transportation and an affiliated entity ("ACT"). ACT is a leading less-than-truckload ("LTL") carrier that also offers dedicated contract carriage and ancillary services.

The total purchase price consideration of $1.31 billion included $1.30 billion in cash and $10.0 million in Knight-Swift shares issued to the sellers at closing. Additionally, the Company assumed $36.7 million in debt, net of cash. Cash was funded from the 2021 Term Loan, as well as existing Knight-Swift liquidity. ACT was an S corporation for tax purposes, and the transaction included an election under Internal Revenue Code Section 338(h)(10). The Stock Purchase Agreement contains customary representations, warranties, and covenants. The results of ACT will be included in our consolidated results beginning in the third quarter of 2021. The Company has not completed the initial accounting for this transaction as it is still in the preliminary stages of assessing the fair value of the underlying tangible and intangible assets.

On July 6, 2021, Knight-Swift entered into the $1.2 billion 2021 Term Loan with Bank of America, N.A. The 2021 Term Loan is incremental to, and is separate from, the 2017 Debt Agreement. The 2021 Term Loan was fully funded on July 6, 2021 and there are no scheduled principal payments prior to maturity in October 2022. The interest rate applicable to the 2021 Term Loan is subject to a leverage-based grid and equals the BSBY rate (Bloomberg Short-term Bank Yield index) plus 1.000% at closing.

The 2021 Term Loan contains similar terms to the 2017 Debt Agreement, including the financial covenants, usual and customary events of default for a facility of this nature, and certain usual and customary restrictions and covenants.

UTXL Enterprises, Inc.

On June 1, 2021, pursuant to a stock purchase agreement (the "SPA") the Company, through a wholly owned subsidiary, acquired 100.0% of the equity interests of UTXL Enterprises, Inc. (“UTXL”), a premier third-party logistics company which specializes in over-the-road full truckload and multi-stop loads.

The total purchase price consideration of $37.2 million, including cash on hand and net working capital adjustments, consisted of $32.2 million in cash to the sellers at closing, which was funded through cash-on-hand and borrowing on the Revolver on the transaction date. At closing $2.25 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations and remains subject to further adjustments.

The purchase price also included contingent consideration consisting of two additional annual payments of up to $2.5 million each (or $5.0 million in total), representing the maximum possible annual deferred payments to the sellers based on UTXL’s operating ratio and revenue growth targets for each of the twelve-month periods ending May 31, 2022 and May 31, 2023.

For income tax purposes, the sale of UTXL's equity interests to the Company is intended to be treated as a sale and purchase of assets. Accordingly, the book and tax basis of the acquired assets and liabilities are the same as of the purchase date. The SPA contains customary representations, warranties, covenants, and indemnification provisions.

The goodwill recognized represents expected synergies from combining the operations of UTXL with the Company, including enhanced service offerings, as well as other intangible assets that did not meet the criteria for separate recognition. The goodwill is expected to be deductible for tax purposes.

The purchase price allocation for the acquisition is preliminary and has been allocated based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date, pending the completion of the valuation of acquired tangible assets, an independent valuation of certain acquired intangible assets, assessment of lease agreements, assessment of certain liabilities, the calculation of deferred taxes based upon the underlying tax basis of assets acquired and liabilities assumed, and assessment of other tax related items. As the Company obtains more information, the preliminary purchase price allocation disclosed below is subject to change. Any future adjustments to the preliminary purchase price allocation, including changes within identifiable intangible assets or estimation uncertainty impacted by market conditions, may impact future net earnings. The purchase price allocation adjustments can be made through the end of the measurement period, which is not to exceed one year from the acquisition date.

Eleos Acquisition

On February 1, 2021, pursuant to a membership interest purchase agreement ("MIPA"), the Company, through a wholly owned subsidiary, acquired 79.44% of the issued and outstanding membership interests of Eleos Technologies, LLC ("Eleos"), a Greenville, South Carolina based software provider, specializing in mobile driving platforms, which complement the Company's suite of services. The total purchase price consideration, including cash on hand and net working capital adjustments, consisted of $41.5 million in cash to the sellers at closing, which was funded through cash-on-hand and borrowing on the Revolver on the transaction date. At closing, $4.1 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations and other items.

The MIPA included that both the buyer and sellers would file an election under the Internal Revenue Code Section 754 to adjust the tax basis of the Company's assets and liabilities, with respect to the buyer's purchase of the equity. The MIPA contains customary representations, warranties, covenants, and indemnification provisions for transactions of this nature.

The goodwill recognized represents expected synergies from combining the operations of Eleos with the Company, including enhanced service offerings, as well as other intangible assets that did not meet the criteria for separate recognition. The goodwill is expected to be deductible for tax purposes.

There were fourteen securities and sixteen securities that were in an unrealized loss position for less than twelve months as of June 30, 2021 and December 31, 2020, respectively. The Company did not recognize any impairment losses related to its held-to-maturity investments during the quarter or year-to-date periods ended June 30, 2021 or 2020.

Embark Convertible Note

During the second quarter of 2021, the Company invested $25.0 million in Embark in exchange for a convertible note. The convertible note accrues simple interest on the unpaid principal balance at a rate of 10.0% and is payable on demand any time after April 16, 2022, unless earlier converted into shares of Embark's common stock. The amount outstanding on the convertible note is automatically converted into a number of shares of Embark's common stock upon either the closing of a qualified financing or upon a public event, subject to discounted conversion pricing per share based on a valuation of Embark.

On June 22, 2021, Embark and Northern Genesis Acquisition Corp II ("NGA"), a publicly-traded special purpose acquisition company ("SPAC"), entered into a definitive business combination agreement that will result in Embark becoming a publicly listed company. Completion of the transaction is expected to occur in the fourth quarter of 2021 and is subject to approval of NGA stockholders and the satisfaction or waiver of certain other customary closing conditions. Based on the valuation of this public event, the Company estimated that the fair value of this investment was $37.6 million and recognized a $12.6 million gain on the convertible note during the quarter ended June 30, 2021.

Refer to Note 15 for additional information regarding fair value measurements of the Company's investments.

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

As of June 30, 2021, management anticipates that the composition and amount of amortization associated with intangible assets will be $24.4 million for the remainder of 2021, $48.8 million in 2022, $48.2 million for each of the years 2023 and 2024, and $48.1 million in 2025. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets, and other events.

Note 7 — Income Taxes

Effective Tax Rate — The quarter-to-date June 30, 2021 and June 30, 2020 effective tax rates were 25.3% and 25.0%, respectively. The year-to-date June 30, 2021 and June 30, 2020 effective tax rates were 25.5% and 26.0%, respectively.

Valuation Allowance — The Company has not established a valuation allowance as it has been determined that, based upon available evidence, a valuation allowance is not required. Management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

Unrecognized Tax Benefits — Management believes it is reasonably possible that a decrease of up to $0.7 million in unrecognized tax benefits relating to federal deductions may be necessary within the next twelve months.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits were approximately $0.4 million and $0.3 million as of June 30, 2021 and December 31, 2020, respectively.

Tax Examinations — Certain of the Company's subsidiaries are currently under examination by various state jurisdictions for tax years ranging from 2013 to 2019. At the completion of these examinations, management does not expect any adjustments that would have a material impact on the Company's effective tax rate. Years subsequent to 2015 remain subject to examination.

Note 8 — Accounts Receivable Securitization

On April 23, 2021, the Company entered into the Fifth Amendment to the Amended and Restated Receivables Sales Agreement ("2021 RSA") which further amended the 2018 RSA. The 2021 RSA is a secured borrowing that is collateralized by the Company's eligible receivables, for which the Company is the servicing agent. The Company's receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to Swift Receivables Company II, LLC ("SRCII") who in turn sells a variable percentage ownership in those receivables to the various purchasers. The Company's eligible receivables are included in "Trade receivables, net of allowance for doubtful accounts" in the condensed consolidated balance sheets. As of June 30, 2021, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

The 2021 RSA is subject to fees, various affirmative and negative covenants, representations and warranties, and default and termination provisions customary for facilities of this type. The Company was in compliance with these covenants as of June 30, 2021. Collections on the underlying receivables by the Company are held for the benefit of SRCII and the various purchasers and are unavailable to satisfy claims of the Company and its subsidiaries.

Note 10 — Contingencies and Legal Proceedings

Legal Proceedings

Information is provided below regarding the nature, status, and contingent loss amounts, if any, associated with the Company's pending legal matters. There are inherent uncertainties in these legal matters, some of which are beyond management's control, making the ultimate outcomes difficult to predict. Moreover, management's views and estimates related to these matters may change in the future, as new events and circumstances arise and the matters continue to develop.

The Company has made accruals with respect to its legal matters where appropriate, which are included in "Accrued liabilities" in the condensed consolidated balance sheets. The Company has recorded an aggregate accrual of approximately $23.9 million, relating to the Company's outstanding legal proceedings as of June 30, 2021.

Based on management's present knowledge of the facts and (in certain cases) advice of outside counsel, management does not believe that loss contingencies arising from pending matters are likely to have a material adverse effect on the Company's overall financial position, operating results, or cash flows after taking into account any existing accruals. However, actual outcomes could be material to the Company's financial position, operating results, or cash flows for any particular period.

Note 14 — Information by Segment and Geography

Segment Information

The Company has three reportable segments: Trucking, Logistics, and Intermodal, as well as the non-reportable segments, discussed below. Based on how economic factors affect the nature, amount, timing, and uncertainty of revenue or cash flows, the Company disaggregates revenues by reportable segment for the purposes of applying the ASC Topic 606 guidance.

The Company's twenty-two operating segments are structured around the types of transportation service offerings provided to our customers, as well as the equipment utilized. In addition, the operating segments may be further distinguished by the Company’s respective brands. The Company aggregated these various operating segments into the three reportable segments discussed below based on similarities with both their qualitative and economic characteristics.

Trucking

The Trucking reportable segment is comprised of nine trucking operating segments that provide similar transportation services to our customers utilizing similar transportation equipment over both irregular (one-way movement) and/or dedicated routes. The Trucking reportable segment consists of irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border operations.

Logistics

The Logistics reportable segment is comprised of six logistics operating segments that provide similar transportation services to our customers and primarily consist of brokerage and other freight management services utilizing third-party transportation providers and their equipment.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

Intermodal

The Intermodal reportable segment is comprised of two intermodal operating segments that provide similar transportation services to our customers. These transportation services include arranging the movement of customers' freight through third-party intermodal rail services on the Company’s trailing equipment (trailers on flat cars and rail containers), as well as drayage services to transport loads between the railheads and customer locations.

Non-reportable

The non-reportable segments include five operating segments that consist of support services provided to the Company's 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 various acquisitions).

Intersegment Eliminations

Certain operating segments provide transportation and related services for other affiliates outside of their segments. For certain operating segments, such services are billed at cost, and no profit is earned. For the other operating segments, revenues for such services are based on negotiated rates, and are reflected as revenues of the billing segment. These rates are adjusted from time to time, based on market conditions. Such intersegment revenues and expenses are eliminated in Knight-Swift's consolidated results.

Geographical Information

In the aggregate, total revenue from the Company's foreign operations was less than 5.0% of consolidated total revenue for the quarter and year-to-date periods ended June 30, 2021 and 2020. Additionally, long-lived assets on the Company's foreign subsidiary balance sheets were less than 5.0% of consolidated total assets as of June 30, 2021 and December 31, 2020.

Note 15 — Fair Value Measurement

ASC Topic 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of June 30, 2021 and December 31, 2020, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.

The estimated fair values of the Company's financial instruments represent management's best estimates of the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. The estimated fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the estimated fair value measurement reflects management's own judgments about the assumptions that market participants would use in pricing the asset or liability. These judgments are developed by the Company based on the best information available under the circumstances.

The following summary presents a description of the methods and assumptions used to estimate the fair value of each class of financial instrument.

Restricted Investments, Held-to-Maturity — The estimated fair value of the Company's restricted investments, held-to-maturity, is based on quoted prices in active markets that are readily and regularly obtainable. See Note 4 for additional disclosures regarding restricted investments, held-to-maturity.

Convertible Notes — The estimated fair value of the Company's convertible note is based on probability weighted discounted cash flow analysis of the corresponding pay-off/redemption.

Equity Method Investments — The estimated fair value of the Company's equity method investments are privately negotiated investments. The carrying amount of these investments approximates the fair value.

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

Equity Securities — The estimated fair value of the Company's investments in equity securities is based on quoted prices in active markets that are readily and regularly obtainable.

Debt Instruments and Leases — For notes payable under the Revolver and the 2017 Term Loan, fair value approximates the carrying value due to the variable interest rate. The carrying values of the 2021 RSA and 2018 RSA approximate fair value, as the underlying receivables are short-term in nature and only eligible receivables (such as those with high credit ratings) are qualified to secure the borrowed amounts. For finance and operating lease liabilities, the carrying value approximates the fair value, as the Company's finance and operating lease liabilities are structured to amortize in a manner similar to the depreciation of the underlying assets.

Contingent Consideration — The estimated fair value of the Company's contingent consideration owed to sellers is calculated using applicable models and inputs for each acquiree.

Other — Cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable represent financial instruments for which the carrying amount approximates fair value, as they are short-term in nature. These instruments are accordingly excluded from the disclosures below. All remaining balance sheet amounts excluded from the below are not considered financial instruments, subject to this disclosure.

The following table presents the carrying amounts and estimated fair values of the Company's major categories of financial assets and liabilities:

Executive Summary

Company Overview

Knight-Swift Transportation Holdings Inc. is North America's largest truckload carrier and a provider of transportation solutions, headquartered in Phoenix, Arizona. 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 shipping solutions to its customers while creating quality driving jobs for our driving associates and successful business opportunities for independent contractors. Our three reportable segments are Trucking, Logistics, and Intermodal. Additionally, we have various non-reportable segments. Refer to Note 14 in Part I, Item 1 of this Quarterly Report for descriptions of our segments.

Our objective is to operate our business with industry-leading margins and growth while providing safe, high-quality, cost-effective solutions for our customers.

ACT Acquisition — On July 5, 2021, we acquired 100% of ACT. ACT is a leading less-than-truckload ("LTL") carrier that also offers dedicated contract carriage and ancillary services. Further details regarding this acquisition are included in Note 3 in Part I, Item 1 of this Quarterly 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 logistics 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 logistics 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 various acquisitions).

•In addition to the revenues earned from our customers for the trucking and non-trucking services discussed above, we also earn fuel surcharge revenue from our customers through our fuel surcharge 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 intangible assets, 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. Our results are affected by various economic, industry, operational, regulatory, and other factors, which are set forth in Part I, Item 1A "Risk Factors" in our 2020 Annual Report, supplemented in Part II, Item 1A "Risk Factors" of this Quarterly Report, and various disclosures in our press releases, stockholder reports, and other filings with the SEC.

1    Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio are non-GAAP financial measures and should not be considered alternatives, or superior to, the most directly comparable GAAP financial measures. However, management believes that presentation of these non-GAAP financial measures provides useful information to investors regarding the Company's results of operations. Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio are reconciled to the most directly comparable GAAP financial measures under "Non-GAAP Financial Measures," below.

2    The average age of our company-owned tractor fleet was 2.4 years and 2.1 years as of June 30, 2021 and 2020, respectively.

3    The average age of our trailer fleet was 8.3 years and 7.6 years as of June 30, 2021 and 2020, respectively.

Market Trends and Company Performance

Trends and Outlook — Our consolidated revenue, excluding trucking fuel surcharge, grew by 15.9% during the first half of 2021, reflecting meaningful growth across all reportable segments. We generated consolidated Adjusted Net Income Attributable to Knight-Swift of $302.4 million, which represents a 75.1% increase from $172.7 million during the first half of 2020. Revenue per tractor was up 9.0% despite lower fleet utilization as a result of the difficult driver sourcing environment. Our Trucking segment increased revenue, excluding fuel surcharge and intersegment transactions, by 7.2%, resulting in a 470 basis point improvement in the Adjusted Operating Ratio to 81.3% in the first half of 2021 from 86.0% in the first half of 2020. Our Logistics segment increased revenue, excluding intersegment transactions by 93.2%. Our Intermodal segment grew revenue 25.3% and improved its Adjusted Operating Ratio by 820 basis points to 95.8% in the first half of 2021, compared to the same period last year. We anticipate ongoing improvement within the Intermodal segment in the coming quarters.

The national unemployment rate was 5.9%1 as of June 30, 2021. The US gross domestic product, which is the broadest measure of goods and services produced across the economy, increased by 6.5%2 and 1.6%2 on a year-over-year and sequential basis, per preliminary third-party forecasts. Third-party forecasts are predicting a continued economic rebound in the second half of 2021, but perhaps at a slower pace. The first half 2021 US employment cost index rose 2.9%1 and 0.7%1 on a year-over-year and sequential basis, respectively.

From a freight market perspective, we are encouraged by the continued strength in freight demand; however, demand may be difficult to predict for the rest of 2021. The 2021 market outlook includes the following:

•we expect the unprecedented demand for over-the-road truckload capacity to continue throughout 2022,

•capacity expansion continues to be limited as new tractor builds are constrained by parts availability, and

•sourcing and retaining drivers will remain challenging and lead to additional driver wage inflation.

The above factors should continue to support a favorable rate environment.

In addition to the above market factors, demand for power-only opportunities continues.

We anticipate that depreciation and amortization expense will increase and rental expense will correspondingly decrease, as a percentage of revenue excluding trucking fuel surcharge, as we intend to purchase, rather than enter into operating leases, for a majority of our revenue equipment in 2021. With significant tightening in the insurance markets, we may also experience changes in premiums, retention limits, and excess coverage limits in the remainder of 2021. While fuel expense is generally offset by fuel surcharge revenue, our fuel expense, net of fuel surcharge revenue may increase in the future.

We expect that our acquisition of ACT will have a significant impact on future financial results, including an overall increase to operating revenues and expenses. However, we are still in the preliminary stages of this transaction and the assessment of the impact on our operations, policies or financial results.

We continue to manage our leverage ratio relative to our targeted range and remain committed to a strong capital structure, which we believe will position us for long-term success and enable us to pursue further opportunities for organic growth, growth through acquisitions, and other capital allocation opportunities. We do not foresee material liquidity constraints or any issues with our ongoing ability to meet our debt covenants.

Segment Review

Trucking Segment

We generate revenue in the Trucking segment primarily through irregular route, dedicated, refrigerated, flatbed, expedited, and cross-border service offerings with 12,967 irregular route tractors and 5,067 dedicated route tractors in use during the quarter-to-date period ended June 30, 2021. Generally, we are paid a predetermined rate per mile or per load for our trucking services. Additional revenues are generated by charging for tractor and trailer detention, loading and unloading activities, dedicated services, and other specialized services, as well as through the collection of fuel surcharge revenue to mitigate the impact of increases in the cost of fuel. The main factors that affect the revenue generated by our Trucking segment are rate per mile from our customers, the percentage of miles for which we are compensated, and the number of loaded miles we generate with our equipment.

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

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

Comparison Between the Quarters Ended June 30, 2021 and 2020 — Operating income grew by 56.3% within the Trucking segment, overcoming inflationary pressures related to sourcing and retaining drivers. Revenue, excluding fuel surcharge and intersegment transactions, grew by 8.2%. Average revenue per tractor increased by 10.3%, driven by an 18.8% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions. Consumer demand remained strong, while capacity remained constrained across our industry, which is driving up sourcing costs and corresponding rates. Our year-over-year rate improvement was partially offset by driver-related sourcing expenses, as well as an 8.0% decline in miles per tractor due to an increase in unseated tractors. On a sequential basis, miles per tractor remained relatively flat.

Comparison Between Year-to-Date June 30, 2021 and 2020 — Operating income grew by 52.0% within the Trucking segment. Revenue, excluding fuel surcharge and intersegment transactions, grew by 7.2%. Average revenue per tractor increased by 9.0%, driven by a 17.5% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions. Our year-over-year rate improvement was partially offset by an increase in driver-related sourcing and other expenses during the first half of 2021, as well as a 7.7% decline in miles per tractor due to inclement weather and an increase in unseated tractors.

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

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

Intermodal Segment

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

Non-reportable Segments

The 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 $11.6 million in quarterly amortization of intangibles related to the 2017 Merger and various acquisitions).

Results of Operations — Consolidated Operating and Other Expenses

Consolidated Operating Expenses

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

			Quarter-to-Date June 30,												Year-to-Date June 30,												QTD 2021 vs.						YTD 2021 vs.
			2021						2020						2021						2020						QTD 2020						YTD 2020
			(Dollars in thousands)																								Increase (Decrease)
Salaries, wages, and benefits			$	377,613					$	365,311					$	747,983					$	720,144					3.4		%				3.9		%
% of total revenue			28.7		%				34.4		%				29.5		%				33.0		%				(570		bps)				(350		bps)
% of revenue, excluding fuel surcharge			31.1		%				36.6		%				31.9		%				35.6		%				(550		bps)				(370		bps)

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

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

Consolidated salaries, wages, and benefits increased by $12.3 million for the second quarter of 2021 and by $27.8 million for the first half of 2021, as compared to the same periods last year. The increases pertained to driving associate pay rates and an non-driver salaries and wages. These were partially offset by a decrease in miles driven by company driving associates and lower medical insurance costs.

% of revenue, excluding trucking fuel surcharge			10.4		%				8.7		%				10.4		%				10.3		%				170		bps				10		bps

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

Our fuel surcharge programs help to offset increases in fuel prices, but apply only to loaded miles and typically do not offset non-paid empty miles, idle time, or out-of-route miles driven. Typical fuel surcharge programs involve a computation based on the change in national or regional fuel prices. These programs may update as often as weekly, but typically require a specified minimum change in fuel cost to prompt a change in fuel surcharge revenue

for our Trucking segment. Therefore, many of these programs have a time lag between when fuel costs change and when the change is reflected in fuel surcharge revenue. Due to this time lag, our fuel expense, net of fuel surcharge, negatively impacts our operating income during periods of sharply rising fuel costs and positively impacts our operating income during periods of falling fuel costs. We continue to utilize our fuel efficiency initiatives such as trailer blades, idle-control, management of tractor speeds, fleet updates for more fuel-efficient engines, management of fuel procurement, and driving associate training programs that we believe contribute to controlling our fuel expense.

The $39.7 million and $36.1 million increases in consolidated fuel expense for the second quarter and first half of 2021, respectively, are attributable to higher average DOE fuel prices when compared to the same periods last year. Average DOE fuel prices were $3.21 per gallon for the second quarter of 2021 and $2.44 per gallon for the second quarter of 2020. Average DOE fuel prices were $3.06 per gallon for year-to-date June 30, 2021 and $2.67 per gallon for year-to-date June 30, 2020.

% of revenue, excluding trucking fuel surcharge			5.9		%				6.6		%				5.9		%				6.6		%				(70		bps)				(70		bps)

Operations and maintenance expense consists of direct operating expenses, such as driving associate hiring and recruiting expenses, equipment maintenance, and tire expense. Operations and maintenance expenses are primarily affected by the age of our company-owned fleet of tractors and trailers and the miles driven. We expect the driver market to remain competitive throughout 2021, which could increase future driving associate development and recruiting costs and negatively affect our operations and maintenance expense. We expect to continue refreshing our tractor and trailer fleet in the coming quarters to maintain or improve the average age of our equipment.

The increases of $5.2 million for the second quarter of 2021 and $4.9 million for the first half of 2021, as compared to the same periods last year, were attributed to higher driving associate hiring expenses and increased chassis expense. This was partially offset by a decrease in miles driven by company driving associates.

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

Consolidated insurance and claims expense increased by $13.5 million for the second quarter of 2021 and by $14.8 million for the first half of 2021, as compared to the same periods last year. These increases were primarily due to negative development within certain prior year losses and costs incurred through our third-party carrier insurance program.

Operating taxes and licenses include state franchise taxes, state and federal highway use taxes, property taxes, vehicle license and registration fees, fuel and mileage taxes, among others. The expense is impacted by changes in the tax rates and registration fees associated with our tractor fleet and regional operating facilities.

The increases of $0.8 million for the second quarter of 2021 and $0.7 million for the first half of 2021, as compared to the same periods last year, were primarily due to higher overall toll expenses. These increases were partially offset by a decrease in total miles driven by our company driving associates.

% of revenue, excluding trucking fuel surcharge			10.2		%				11.5		%				10.4		%				11.1		%				(130		bps)				(70		bps)

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

Consolidated depreciation and amortization of property and equipment increased by $9.0 million for the second quarter of 2021 and increased by $18.7 million for the first half of 2021, as compared to the same periods last year. These increases were primarily related to an increase in owned versus leased equipment.

We expect consolidated depreciation and amortization of property and equipment to increase both in total and as a percentage of consolidated revenue, excluding trucking fuel surcharge, as we currently do not plan to use operating leases as a primary means of funding our equipment purchases in the remainder of 2021.

Purchased transportation expense is comprised of payments to independent contractors in our trucking operations, as well as payments to third-party capacity providers related to logistics, freight management, and non-trucking services in our logistics and intermodal businesses.  Purchased transportation is generally affected by capacity in the market as well as changes in fuel prices. As capacity tightens, our payments to third-party capacity providers and to independent contractors tend to increase. Additionally, as fuel prices increase, payments to third-party capacity providers and independent contractors increase.

We expect purchased transportation will increase as a percentage of revenue if we grow our logistics and intermodal businesses faster than our trucking business. The increase could be partially offset if independent contractors exit the market due to regulatory changes.

Consolidated purchased transportation expense increased by $104.1 million for the second quarter of 2021 and increased by $137.0 million for the first half of 2021, as compared to the same periods last year. These increases were primarily due to payments made to third-party carriers, partially offset by a decrease in miles driven by independent contractors of 8.3% for the second quarter of 2021 and 10.7% the first half of 2021, as compared to the same periods last year.

Miscellaneous operating expenses			$	11,331					$	20,778					$	25,924					$	43,794					(45.5		%)				(40.8		%)

Miscellaneous operating expenses primarily consist of legal and professional services fees, general and administrative expenses, other costs, as well as net gain on sales of equipment.

•Comparison Between the Quarters Ended June 30, 2021 and 2020 — The decrease in net consolidated miscellaneous operating expenses was primarily due to a $13.4 million increase in gain on sales of equipment.

•Comparison Between Year-to-Date June 30, 2021 and 2020 — The decrease in net consolidated miscellaneous operating expenses was primarily due to a $20.9 million increase in gain on sales of equipment.

Income tax expense			51,783						26,815						97,112						51,369						93.1		%				89.0		%

Interest expense — Interest expense is comprised of debt and finance lease interest expense as well as amortization of deferred loan costs. The quarter and year-to-date decreases in interest expense were primarily due to lower overall interest rates. We expect interest expense to increase during the second half of 2021 due to the inclusion of the 2021 Term Loan which was entered into subsequent to June 30, 2021.

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

•Comparison Between the Quarters Ended June 30, 2021 and 2020 — The $8.3 million favorable change between the second quarter of 2021 and the second quarter of 2020 is primarily driven by unrealized gains recognized from our investment in Embark, partially offset by a reduction in unrealized gains recognized for other investments within our portfolio.

•Comparison Between Year-to-Date June 30, 2021 and 2020 — The $31.0 million favorable change between the first half of 2021 and the first half of 2020 is primarily due to the Embark gain discussed above and an increase in unrealized gains recognized for other investments within our portfolio.

Income tax expense — In addition to the discussion below, Note 7 in Part I, Item 1 of this Quarterly Report provides further analysis related to income taxes.

•Comparison Between the Quarters Ended June 30, 2021 and 2020 — The $25.0 million increase in consolidated income tax expense was primarily due to an increase in income before income taxes resulting in an effective tax rate of 25.3% for the second quarter of 2021 and 25.0% for the second quarter of 2020.

•Comparison Between Year-to-Date June 30, 2021 and 2020 — The $45.7 million increase in consolidated income tax expense was primarily due to an increase in income before income taxes resulting in an effective tax rate of 25.5% for the first half of 2021 and 26.0% for the first half of 2020.

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

Non-GAAP Financial Measures

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

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

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

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

Liquidity and Capital Resources

Sources of Liquidity

Our primary sources of liquidity are funds provided by operations and the following:

Source						June 30, 2021
						(In thousands)
Cash and cash equivalents, excluding restricted cash						$	179,032
Availability under Revolver, due October 2022 1						708,408
Availability under 2021 RSA, due April 2024 2						55,719
Total unrestricted liquidity						$	943,159
Cash and cash equivalents – restricted 3						53,035
Restricted investments, held-to-maturity, amortized cost 3						8,589
Total liquidity, including restricted cash and restricted investments						$	1,004,783

1    As of June 30, 2021, we had $55.0 million in borrowings under our $800.0 million Revolver. We additionally had $36.6 million in outstanding letters of credit (discussed below), leaving $708.4 million available under the Revolver.

2    Based on eligible receivables at June 30, 2021, our borrowing base for the 2021 RSA was $400.0 million, while outstanding borrowings were $279.0 million. We additionally had $65.3 million in outstanding letters of credit (discussed below), leaving $55.7 million available under the 2021 RSA. Refer to Note 8 in Part I, Item 1 of this Quarterly Report for more information regarding the 2021 RSA.

3    Restricted cash and restricted investments are primarily held by our captive insurance companies for claims payments. "Cash and cash equivalents – restricted" consists of $51.6 million, included in "Cash and cash equivalents — restricted" in the condensed consolidated balance sheet and held by Mohave and Red Rock for claims payments. The remaining $1.4 million is included in "Other long-term assets" and is held in escrow accounts to meet statutory requirements.

Uses of Liquidity

Our business requires substantial amounts of cash for operating activities, including salaries and wages paid to our employees, contract payments to independent contractors, insurance and claims payments, tax payments, and others. We also use large amounts of cash and credit for the following activities:

Capital Expenditures — When justified by customer demand, as well as our liquidity and our ability to generate acceptable returns, we make substantial cash capital expenditures to maintain a modern company tractor fleet, refresh our trailer fleet, fund replacement of our revenue equipment fleet, and, to a lesser extent, fund upgrades to our terminals and technology in our various service offerings. We expect that net capital expenditures from the aforementioned projects will be in the range of $500.0 – $550.0 million for the full-year 2021, including anticipated net cash capital expenditures of ACT. The range provided excludes cash outlays for potential acquisitions. We believe we have ample flexibility with our trade cycle and purchase agreements to alter our current plans if economic or other conditions warrant.

Over the long-term, we will continue to have significant capital requirements, which may require us to seek additional borrowing, lease financing, or equity capital. The availability of financing or equity capital will depend upon our financial condition and results of operations as well as prevailing market conditions. If such additional borrowing, lease financing, or equity capital is not available at the time we need it, then we may need to borrow more under the Revolver (if not then fully drawn), extend the maturity of then-outstanding debt, rely on alternative financing arrangements, engage in asset sales, limit our fleet size, or operate our revenue equipment for longer periods.

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

There can be no assurance that we will be able to obtain additional debt under our existing financial arrangements to satisfy our ongoing capital requirements. However, we believe the combination of our expected cash flows, financing available through operating and finance leases, available funds under our accounts receivable securitization, and availability under the Revolver will be sufficient to fund our expected capital expenditures for at least the next twelve months.

Principal and Interest Payments — As of June 30, 2021, we had debt, accounts receivable securitization, and finance lease obligations of $870.7 million, which are discussed under "Material Debt Agreements," below. Certain cash flows from operations are committed to minimum payments of principal and interest on our debt and lease obligations. Additionally, when our financial position allows, we periodically make voluntary prepayments on our outstanding debt balances. Subsequent to June 30, 2021, we acquired ACT and borrowed $1.2 billion pursuant to the 2021 Term Loan to finance the transaction.

Letters of Credit — Pursuant to the terms of the 2017 Debt Agreement and the 2021 RSA, our lenders may issue standby letters of credit on our behalf. When we have letters of credit outstanding, the availability under the Revolver or 2021 RSA is reduced accordingly. Standby letters of credit are typically issued for the benefit of regulatory authorities, insurance companies and state departments of insurance for the purpose of satisfying certain collateral requirements, primarily related to our automobile, workers' compensation, and general insurance liabilities.

Share Repurchases — From time to time, and depending on free cash flow availability, debt levels, common stock prices, general economic and market conditions, as well as Board approval, we may repurchase shares of our outstanding common stock. As of June 30, 2021, the Company had $196.3 million remaining under the 2020 Knight-Swift Share Repurchase Plan. Additional details are discussed in Note 11 in Part I, Item 1 of this Quarterly Report.

Working Capital

We had a working capital surplus of $369.3 million as of June 30, 2021 and $83.7 million as of December 31, 2020.

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

Cash Flow Analysis

			Year-to-Date June 30,												Change
			2021						2020
			(In thousands)
Net cash provided by operating activities			$	459,504					$	383,360					$	76,144
Net cash used in investing activities			(196,916)						(253,066)						56,150
Net cash used in financing activities			(227,798)						(173,771)						(54,027)

Net Cash Provided by Operating Activities

Comparison Between Year-to-Date June 30, 2021 and 2020 — The $76.1 million increase in net cash provided by operating activities was primarily due to a $149.1 million increase in operating income and a $4.7 million decrease in interest payments, partially offset by a $129.7 million increase in income tax payments. The remaining difference is attributed to various changes in working capital.

Net Cash Used in Investing Activities

Comparison Between Year-to-Date June 30, 2021 and 2020 — The $56.2 million decrease in net cash used in investing activities was primarily due to a $74.7 million decrease in net cash capital expenditures, partially offset by $25.0 million spent on our investment in Embark's convertible note.

Net Cash Used in Financing Activities

Comparison Between Year-to-Date June 30, 2021 and 2020 — Net cash used in financing activities increased by $54.0 million, primarily due to a $24.5 million increase in net repayments of our debt and finance lease obligations and a $19.0 million increase in repurchases of our common stock.

Seasonality

Discussion regarding the impact of seasonality on our business is included in Note 1 in the notes to the condensed consolidated financial statements, included in Part I, Item 1 of this Quarterly Report, incorporated by reference herein.

Inflation

Inflation can have an impact on our operating costs. A prolonged period of inflation could cause interest rates, fuel, wages, and other costs to increase, which would adversely affect our results of operations unless freight rates correspondingly increased. Consistent with trends in the trucking industry overall, we continue to experience inflationary pressures with respect to driver wages, as compared to prior years.

Recently Issued Accounting Pronouncements

See Note 2 in Part I, Item 1 of this Quarterly Report, which is incorporated herein by reference, for the impact of recently issued accounting pronouncements on the Company's condensed consolidated financial statements.

ITEM 3.			QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have exposure from variable interest rates, primarily related to our 2017 Debt Agreement and 2021 RSA. These variable interest rates are impacted by changes in short-term interest rates. We primarily manage interest rate exposure through a mix of variable rate debt (weighted average rate of 1.1% as of June 30, 2021) and fixed rate equipment lease financing. Assuming the level of borrowings as of June 30, 2021, a hypothetical one percentage point increase in interest rates would increase our annual interest expense by $6.3 million.

Commodity Price Risk

We have commodity exposure with respect to fuel used in company-owned tractors. Increases in fuel prices would continue to raise our operating costs, even after applying fuel surcharge revenue. Historically, we have been able to recover a majority of fuel price increases from our customers in the form of fuel surcharges. The weekly average of diesel price per gallon in the US increase to $3.21 for the second quarter of June 30, 2021 from an average of $2.44 in the second quarter of June 30, 2020. The weekly average of diesel price per gallon in the US increased to $3.06 for the year-to-date June 30, 2021 from an average of $2.67 in the year-to-date June 30, 2020. We cannot predict the extent or speed of potential changes in fuel price levels in the future, the degree to which the lag effect of our fuel surcharge programs will impact us as a result of the timing and magnitude of such changes, or the extent to which effective fuel surcharges can be maintained and collected to offset such increases. We generally have not used derivative financial instruments to hedge our fuel price exposure in the past, but continue to evaluate this possibility. To mitigate the impact of rising fuel costs, we contract with some of our fuel suppliers to buy fuel at a fixed price or within banded pricing for a specified period, usually not exceeding twelve months. However, these purchase commitments only cover a small portion of our fuel consumption. Accordingly, fuel price fluctuations may still negatively impact us.

ITEM 4.			CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board. Our management, with the participation of our principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures. Based on this evaluation, as of the end of the period covered by this Quarterly Report on Form 10-Q our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and (2) accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We base our internal control over financial reporting on the criteria set forth in the 2013 COSO Internal Control: Integrated Framework.

We have confidence in our disclosure controls and procedures and internal control over financial reporting. Nevertheless, our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures and internal control over financial reporting will prevent all errors, misstatements, or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a

55

control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

PART II OTHER INFORMATION

ITEM 1.			LEGAL PROCEEDINGS

Information about our legal proceedings is included in Note 10 of the notes to our condensed consolidated financial statements, included in Part I, Item 1, of this Quarterly Report for the period ended June 30, 2021, and is incorporated by reference herein. Based on management's present knowledge of the facts and (in certain cases) advice of outside counsel, management does not believe that loss contingencies arising from pending matters are likely to have a material adverse effect on the Company's overall financial position, operating results, or cash flows after taking into account any existing accruals. However, actual outcomes could be material to the Company's financial position, operating results, or cash flows for any particular period.

ITEM 1A.			RISK FACTORS

While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present. Our 2020 Annual Report in the section entitled "Item 1A. Risk Factors," describes some of the risks and uncertainties associated with our business. In addition to the risk factors set forth in our Form 10-K, we believe the following additional risks and uncertainties should be considered in evaluating our business and growth outlook:

Our acquisition of ACT presents certain additional risks to our business and operations.

On July 5, 2021, we acquired ACT, a leading LTL carrier that also offers dedicated contract carriage and ancillary services. The acquisition presents certain additional risks to our business and operations, including, among other things:

•prior to the acquisition of ACT, our management team had limited experience with LTL operations and therefore may be challenged in managing the LTL operations, particularly if there were a loss of the ACT management team;

•LTL operations are more capital intensive than truckload operations, including the need for additional terminals and types of equipment;

•LTL operations require more human capital than truckload operations, including the need for dock employees and maintenance technicians, both of which are difficult to recruit and retain given the tight labor market;

•potential adverse reactions or changes to business relationships resulting from the completion of the acquisition, including potential breakdown of alliances between ACT and its capacity providers that are needed to meet customer requirements; and

•increased workers' compensation incidence rates generally associated with LTL operations.

In addition to the risks regarding unionization set forth in our Form 10-K, the unionization of any of our employees, including within ACT’s LTL operations, could have a material adverse effect on our business, customer retention, financial condition, results of operations, and liquidity, and could cause significant disruption of, or inefficiencies in, our operations, because:

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

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

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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

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

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

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

In addition, material differences in results as compared with those expected from the acquisition could arise due to those risks and uncertainties described in our Form 10-K Risk Factors, including, among other things, business disruption, operational problems, financial loss, technology and financial reporting and internal controls integration, legal liability to third parties and similar risks, any of which could have a material adverse effect on our business, customer retention, financial condition, results of operations, or liquidity.
