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 quarteryear-to-date period ended March 31,September 30, 2021, the Company operated an average of 18,22418,041 tractors (comprised of 16,30516,166 company tractors and 1,9191,875 independent contractor tractors) and 59,79760,396 trailers within the TruckingTruckload segment. Additionally, the Company operated an average of 597605 tractors and 10,84610,843 containers in the Intermodal segment. TheAs of September 30, 2021, the Company's 34 reportable segments are Trucking,were Truckload, Logistics, Intermodal, and Intermodal.LTL.
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.
Note regarding comparability — The reported results do not include ACT's operating results prior to its acquisition by the Company on July 5, 2021 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's third quarter 2021 results and prior periods may not be meaningful.
Change in Accounting Estimate
In September 2021, the Company increased the useful life for a certain group of its trailers, given recent trends in the used trailer market. Management prospectively accounted for this as a change in accounting estimate. This increased "Depreciation and amortization of property and equipment" in the condensed consolidated statements of comprehensive income by approximately $0.6 million for the quarter and year-to-date periods ended September 30, 2021, which immaterially affected basic and diluted earnings per share.
Seasonality
In the truckload 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 Truckload 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, as the Company continues to diversify its business through expansion into the LTL industry, warehousing, and other activities, seasonal volatility is becoming more tempered. Additionally, macroeconomic trends and cyclical changes

in the trucking industry, including imbalances in supply and demand, can override the seasonality faced in the industry.
Impact of COVID-19
COVID-19 became a global pandemic in 2020, which triggered a significant downturn in the global economy. The Company continues to operate its business through the COVID-19 pandemic, including its 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
ACT
On July 5, 2021, the Company acquired 100% of Dothan, Alabama-based ACT. ACT is a leading 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 sellers at closing. Additionally, the Company assumed $36.5 million in debt, net of cash. Cash was funded from the July 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). 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, and covenants.
The Company's condensed consolidated financial statements for the quarter and year-to-date periods ended September 30, 2021 include ACT's operating results beginning July 5, 2021 (closing of the acquisition) through September 30, 2021. During the quarter and year-to-date periods ended September 30, 2021, the Company's consolidated operating results included ACT's total revenue of $191.9 million and net income of $13.4 million. ACT's net income, during the quarter and year-to-date periods ended September 30, 2021, included $3.5 million related to the amortization of intangible assets acquired in the ACT Acquisition.
The goodwill recognized represents expected synergies from combining the operations of ACT 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 unaudited pro forma condensed combined financial information has been presented for comparative purposes only and includes certain adjustments such as recognition of assets acquired at estimated fair values and related depreciation and amortization, elimination of transaction costs incurred by Knight-Swift and ACT during the periods presented that were directly related to the ACT Acquisition, and related income tax effects of these items. As a result of the ACT Acquisition, the Company incurred certain acquisition-related expenses totaling $2.4 million and $2.7 million during the quarter and year-to-date periods ended September 30, 2021, respectively. These expenses were eliminated in the presentation of the unaudited pro forma "Net income attributable to Knight-Swift" presented above.
The unaudited pro forma condensed combined financial information does not purport to represent the actual results of operations that Knight-Swift and ACT would have achieved had the companies been combined during the periods presented in the unaudited pro forma condensed combined financial statements and is not intended to project the future results of operations that the combined company may achieve after the identified transactions. The unaudited pro forma condensed combined financial information does not reflect any cost savings that may be realized as a result of the ACT Acquisition and also does not reflect any restructuring or integration-related costs to achieve those potential cost savings.
UTXL
On June 1, 2021, pursuant to an SPA the Company, through a wholly owned subsidiary, acquired 100.0% of the equity interests of 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 2017 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 operating ratio and revenue growth targets for each of the twelve-month periods ending May 31, 2022 and May 31, 2023. As of September 30, 2021, $2.5 million is included in "Accrued liabilities" and $2.5 million is included in "Other long-term liabilities" in the Company's condensed consolidated balance sheets, depending on the expected payment dates.
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 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.

1The interest rate margin for the 2021 Term Loans and 2021 Revolver is based on the Company's consolidated leverage ratio. As of September 30, 2021, interest accrued at 1.1% on the 2021 Term Loans and 1.2% on the 2021 Revolver.
2The commitment fee for the unused portion of the 2021 Revolver is based on the Company's consolidated leverage ratio, and ranges from 0.1% to 0.2%. As of September 30, 2021, commitment fees on the unused portion of the 2021 Revolver accrued at 0.1% and outstanding letter of credit fees accrued at 1.1%.
Pursuant to the 2021 Debt Agreement, the 2021 Revolver and the 2021 Term Loans contain certain financial covenants with respect to a maximum net leverage ratio and a minimum consolidated interest coverage ratio. The 2021 Debt Agreement provides flexibility regarding the use of proceeds from asset sales, payment of dividends, stock repurchases, and equipment financing. In addition to the financial covenants, the 2021 Debt Agreement includes usual and customary events of default for a facility of this nature and provides that, upon the occurrence and continuation of an event of default, payment of all amounts payable under the 2021 Debt Agreement may be accelerated, and the lenders' commitments may be terminated. The 2021 Debt Agreement contains certain usual and customary restrictions and covenants relating to, among other things, dividends (which are restricted only if a default or event of default occurs and is continuing or would result therefrom), liens, affiliate transactions, and other indebtedness. As of September 30, 2021, the Company was in compliance with the covenants under the 2021 Debt Agreement.
Borrowings under the 2021 Debt Agreement, are made by Knight-Swift Transportation Holdings Inc., and are guaranteed by certain of the Company's domestic subsidiaries (other than its captive insurance subsidiaries, driving academy subsidiary, and bankruptcy-remote special purpose subsidiary).
July 2021 Term Loan — On July 6, 2021, Knight-Swift entered into a $1.2 billion term loan with Bank of America, N.A (the "July 2021 Term Loan"). The July 2021 Term Loan was incremental to, and was separate from, the 2017 Debt Agreement. The July 2021 Term Loan was fully funded on July 6, 2021 and there were no scheduled principal payments prior to its maturity in October 2022. The interest rate applicable to the July 2021 Term Loan was subject to a leverage-based grid and equaled the BSBY rate plus 1.000% at closing. The July 2021 Term Loan was paid off and terminated using the proceeds of the 2021 Term Loans, discussed above.
The July 2021 Term Loan contained 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.

ACT Credit Agreement
Prudential Notes —Through the acquisition of ACT, the Company assumed the Second Amended and Restated Note Purchase and Private Shelf Agreement with Prudential Capital Group ("2014 Prudential Notes"). On September 3, 2021, ACT entered into the 2021 Prudential Notes, replacing the 2014 Prudential Notes. The 2021 Prudential Notes have interest rates ranging from 4.05% to 4.40% and various maturity dates ranging from October 2023 through January 2028.
The 2021 Prudential Notes allow ACT to borrow up to $125 million, less amounts then currently outstanding with Prudential Capital Group, provided that certain financial ratios are maintained. The 2021 Prudential Notes are unsecured and contain usual and customary restrictions on, among other things, the ability to make certain payments to stockholders, similar to the provisions of the Company's 2021 Debt Agreement. As of September 30, 2021, ACT had $77.1 million available under the agreement.
See Note 15 for fair value disclosures regarding the Company's debt instruments.
Note 10 — Defined Benefit Pension Plan
Through the ACT Acquisition, the Company assumed a defined benefit pension plan covering ACT's drivers, drivers' helpers, warehousemen, warehousemen's helpers, mechanics, and mechanics' helpers. The plan provides normal retirement benefits based on years of credited service and applicable benefit units as defined by the plan. Provision is also made for early and defined retirements.
The pension plan was amended such that benefit accrual and plan participation for the plan were effectively frozen as of January 1, 1997, resulting in a curtailment on that date. The net pension liability recognized is as follows:

"Other comprehensive loss" in the condensed consolidated statements of comprehensive income included a $0.9 million loss from pension plan adjustments during the third quarter of 2021. The provisions of the plan do not require compensation levels to be considered in determining the plan’s benefit obligation. As such, the accumulated benefit obligation and projected benefit obligation are the same.

Assumptions
A weighted-average discount rate of 2.53% was used to determine benefit obligations as of September 30, 2021.
The following weighted-average assumptions were used to determine net periodic pension cost:
Quarter-to-Date September 30,
2021
Discount rate2.49 %
Expected long-term rate of return on pension plan assets6.00 %
ACT's assumptions for the expected long-term rate of return on pension plan assets are based on a periodic review of the plan’s asset allocation over a long-term period. Expectations of returns for each asset class are based on comprehensive reviews of historical data and economic/financial market theory. The expected long-term rate of return on pension plan assets was selected from within the reasonable range of rates determined by (1) historical real returns, net of inflation, for the asset classes covered by the investment policy and (2) projections of inflation over the long-term period during which benefits are payable to plan participants.
The defined benefit pension plan weighted-average asset allocations, by asset category, are as follows:
September 30, 2021
Asset category:
Equity securities30 %
Debt securities69 %
Cash and cash equivalents%
Total100 %
Pension plan assets
The target allocation by asset category, is as follows:
September 30, 2021
Asset category:
Equity securities30 %
Debt securities70 %
Total100 %
The investment policy includes various guidelines and procedures designed to ensure assets are invested in a manner necessary to meet expected future benefit payments. The investment guidelines consider a broad range of economic conditions. Central to the policy are target allocation percentages (shown above) by major asset categories. The objectives of the target allocation percentages are to maintain investment portfolios that diversify risk through prudent asset allocation parameters and achieve asset returns that meet or exceed the plan’s actuarial assumptions.
Refer to Note 15 for additional information regarding fair value measurements of the Company's investments.

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 $21.8$18.4 million, relating to the Company's outstanding legal proceedings as of March 31,September 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 3 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-one 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 five 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.
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.

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 March 31,September 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.
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.
Pension Plan Assets — The estimated fair value of ACT's pension plan assets are based on quoted prices in active markets that are readily and regularly obtainable.
Debt Instruments and Leases — For notes payable under the 2017 Revolver, the 2017 Term Loan, the 2021 Revolver and the 2021 Term Loan,Loans, fair value approximates the carrying value due to the variable interest rate. The carrying valuevalues of the 2021 RSA and 2018 RSA approximatesapproximate 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 Warehousing Co.'s sellersellers is calculated using a Monte Carlo simulation model based on the acquiree's earnings before interestapplicable models and taxes.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.

Note 17 — Information by Segment and Geography
Segment Information
The Company has 4 reportable segments: Truckload, Logistics, Intermodal, and LTL, 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 ASC Topic 606, Revenue from Contracts with Customers.
The Company's NaN 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 four reportable segments discussed below based on similarities with both their qualitative and economic characteristics.
Truckload
The Truckload reportable segment is comprised of nine truckload operating segments that provide similar transportation services to the Company's customers utilizing similar transportation equipment over both irregular (one-way movement) and/or dedicated routes.The Truckload 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 the Company's customers and primarily consist of brokerage and other freight management services utilizing third-party transportation providers and their equipment.
Intermodal
The Intermodal reportable segment is comprised of two intermodal operating segments that provide similar transportation services to the Company's 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.
LTL
The LTL reportable segment is comprised of one operating segment and provides our customers with regional LTL transportation services through a network of over 70 service centers in the Company's geographical footprint. The Company's LTL service also includes national coverage to customers by utilizing partner carriers for areas outside of the Company's direct network.
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.

Executive Summary
Company Overview
Knight-Swift Transportation Holdings Inc. is one of the largest and most diversified freight transportation companies, operating the largest full truckload fleet in North America's largest truckload carrierAmerica and a provider of transportation solutions,is 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 full truckload and LTL 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 threefour reportable segments are Trucking,Truckload, Logistics, Intermodal, and Intermodal.LTL. Additionally, we have various non-reportable segments. Refer to Note 1417 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. Further details regarding this acquisition are included in Note 3 in Part I, Item 1 of this Quarterly Report.
Revenue
Our truckingtruckload 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 TruckingTruckload 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 LTL service provides our customers regional LTL transportation service through our network of over 70 service centers in our geographical footprint. Our LTL service also provides national coverage to our customers by utilizing partner carriers for areas outside of our direct network.
Our non-reportable segments includeIron Truck Services, (which offers support services provided to our customers and independent contractors (includingincluding 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.Truckload and LTL segments.

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 II, Item 1A "Risk Factors" of this Quarterly Report, Part II, Item 1A "Risk Factors" of our Quarterly Report for the quarter-ended June 30, 2021, Part I, Item 1A "Risk Factors" in our 2020 Annual Report, and various disclosures in our press releases, stockholder reports, and other filings with the SEC.

Our Logistics segment grew revenue by more than 50% and more than doubled operating income year-over-year. Despite weather and service disruptions duringwithin the first quarter of 2021, our Intermodal segment achieved year-over-year improvements in operating results, and we anticipate ongoing improvement in the coming quarters.four reportable segments.
The national unemployment rate was 6.0%4.8%1 as of March 31, 2021, reflecting the continued resumption of economic activity that had been curtailed due to the pandemic.
During the first quarter of 2021, theSeptember 30, 2021. The US gross domestic product, which is the broadest measure of goods and services produced across the economy, increased by 6.4%2.0%2 on a year-over-year basis, per preliminary third-party forecasts.

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:
over-the-roadin addition to expecting unprecedented demand in the fourth quarter of 2021, we anticipate similar strength for truckload demand has been strong and we expect this to continueservices throughout the remainder of the year and into 2022,
capacity expansion maycontinues to be limited as there has been some constraintnew tractor and trailer builds are constrained by parts availability, with respect to new tractor builds,
rates may continue to be favorable in the coming year, as a result of inventory restocking and strong demand,labor shortages,
sourcing and retaining drivers is likely to contributewill remain challenging and lead to additional driver wage inflation,
there has been an increased demand for power-only services, and
there may be continuing non-contract freightinflationary pressure on equipment, maintenance, labor and other cost items.
The above factors should continue to support a favorable rate environment, likely resulting in double digit contract rate increases. In addition to the above, we are seeing strong demand for power-only opportunities with more challenging year-over-year comparisonsand strength in the back half of the year.used equipment market.
We anticipate that depreciation and amortization expense will increase and rental expense will correspondingly decrease, as a percentage of revenue excluding truckingtruckload 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 continue to manageexpect that our leverage ratio relative to our targeted rangeacquisition of ACT will have a significant impact on future financial results, including an overall increase in operating revenues 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. expenses.
We do not foresee material liquidity constraints or any issues with our ongoing ability to meet our debt covenants.

Segment Review
TruckingTruckload Segment
We generate revenue in the TruckingTruckload segment primarily through irregular route, dedicated, refrigerated, flatbed, expedited, and cross-border service offerings with 13,13012,937 irregular route tractors and 5,0944,930 dedicated route tractors.tractors in use during the quarter-to-date period ended September 30, 2021. Generally, we are paid a predetermined rate per mile or per load for our truckingtruckload 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 TruckingTruckload 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 TruckingTruckload 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 TruckingTruckload segment are depreciation and rent expenses from leasing and acquiring revenue equipment and terminals, as well as compensating our non-driver employees.

Comparison Between the Quarters Ended September 30, 2021 and 2020The Adjusted Operating Ratio improved by 350 basis points to 77.8%, leading to a 22.3% improvement in Adjusted Operating Income. Year-over-year revenue, excluding fuel surcharge and intersegment transactions, grew by 3.4%. A 24.9% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions, partially offset by a 13.6% decrease in miles per tractor, contributed to a 6.8% increase in average revenue per tractor. Shipping demand remains strong throughout all markets. We have experienced more opportunities in shorter length of haul lanes, which have resulted in higher revenue per mile but fewer miles per tractor. These opportunities ultimately contributed to higher revenue per tractor and improved margins.
Comparison Between Year-to-Date September 30, 2021 and 2020The Adjusted Operating Ratio improved by 420 basis points to 80.1%, leading to a 34.3% improvement in Adjusted Operating Income.

A 19.8% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions, partially offset by a 9.7% decrease in miles per tractor, contributed to an 8.2% increase in average revenue per tractor.
Logistics Segment
The Logistics segment is less asset-intensive than the Trucking segmentTruckload and LTL segments 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.

LTL Segment
Our LTL segment is a regional motor carrier headquartered in Dothan, Alabama. We provide regional direct service and serve our customers' national transportation needs by utilizing key partner carriers for coverage areas outside of our network. We primarily generate revenue by transporting freight for our customers through our core LTL services.
Our revenues are impacted by shipment volume and tonnage levels that flow through our network. Additional revenues are generated through fuel surcharges and accessorial services provided during transit from shipment origin to destination. We focus on the following multiple revenue generation factors when reviewing revenue yield: revenue per hundredweight, revenue per shipment, weight per shipment, and length of haul. Fluctuation within each of these metrics is analyzed when determining the revenue quality of our customers' shipment density.
Our most significant expense is related to direct costs associated with the transportation of our freight moves including; direct salary, wage and benefit costs, fuel expense, and depreciation expense associated with revenue equipment costs. Other expenses associated with revenue generation that can fluctuate and impact operating results are insurance and claims expense as well as maintenance costs of our revenue equipment. These expenses can be influenced by multiple factors including our safety performance, equipment age, and other factors. A key component to lowering our operating costs is labor efficiency within our network. We continue to focus on technological advances to improve the customer experience and reduce our operating costs.

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 truckingtruckload fuel surcharge. TruckingTruckload 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 truckingtruckload fuel surcharge is a better measure for analyzing many of our expenses and operating metrics.

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.

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 TruckingTruckload 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.
Comparison Between the Quarters Ended September 30, 2021 and 2020The $3.6$41.7 million decreaseincrease in consolidated fuel expense for the third quarter, includes $15.2 million of fuel expense from ACT's results.

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 and into 2022, 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.
Comparison Between the Quarters Ended September 30, 2021 and 2020The firstincrease of $17.0 million for the third quarter decrease of $0.32021 includes $9.3 million inconsolidated operations and maintenance expense from ACT's results. The remaining increase was attributed to reduced maintenance expense associated with refreshing our fleet with newer equipmenthigher driving associate hiring expenses and theincreased chassis expense. This was partially offset by a decrease in miles driven by company driving associates noteddiscussed above.

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. In 2021, we expanded our insurance offerings to third-party carriers, earning additional premium revenues, which were partially offset by increased insurance reserves. 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.
Comparison Between the Quarters Ended September 30, 2021 and 2020Consolidated insurance and claims expense increased by $1.4$28.6 million for the third quarter of 2021, as compared to the third quarter of 2020. This increase includes $7.7 million of insurance and claims expense from ACT's results. The remaining increase was primarily due to insurance reserves incurred through our third-party carrier insurance program.
Comparison Between Year-to-Date September 30, 2021 and 2020 — Consolidated insurance and claims expense increased by $43.4 million for the year-to-date period ended March 31,September 30, 2021, as compared to the same period last year. This increase includes $7.7 million of insurance and claims expense from ACT's results. The remaining increase was primarily due to negative development within certain prior year claims.insurance reserves incurred through our third-party carrier insurance program.

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 $9.7 million for the quarter ended March 31, 2021, when compared to the same period last year. The increase was 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.
Consolidated purchased transportation expense increased by $107.0 million for the third quarter of 2021 and increased by $244.0 million for the year-to-date period ended September 30, 2021, as compared to the same periods last year. This increase includes $3.3 million of expense from ACT's results. The comparative period increases were primarily due to payments made to third-party carriers, partially offset by a decrease in miles driven by independent contractors of 17.7% for the third quarter of 2021 and 13.1% for the year-to-date period ended September 30, 2021.
We expect purchased transportation will increase as a percentage of revenue if we grow our logistics and intermodal businesses faster than our trucking business.truckload and LTL businesses. The increase could be partially offset if independent contractors exit the market due to regulatory changes.

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.

1    "Amortization of intangibles" reflects the non-cash amortization expense relating to intangible assets identified in the 2017 Merger, the ACT Acquisition, and other acquisitions. Refer to Note 3 in Part I, Item 1 of this Quarterly Report for additional details regarding theour acquisition.
2    "Impairments" for reflects the firstnon-cash impairment of certain tractors (within the Truckload segment) and certain legacy trailers (within the non-reportable segments) as a result of a softer used equipment market during the second quarter of 2020, reflect the as well as impairment charges of trailer tracking equipment (within the TruckingTruckload segment). during the first quarter of 2020.
3    "Legal accruals" are included in "Miscellaneous operating expenses" in the condensed consolidated statements of comprehensive income and reflect costs related to certain class action lawsuits arising from employee and contract related matters. During the third quarter of 2021, the Company reversed an accrued legal matter previously identified as probable in 2019. This was based on the recent decision of the appellate court, resulting in a change to a remote likelihood that a loss was incurred.
4    "COVID-19 incremental costs" reflects costs incurred during 2020 that were directly attributable to the pandemic and were incremental to those incurred prior to the outbreak. These include payroll premiums paid to our driving associates and shop technicians, additional disinfectants and cleaning supplies, and various other pandemic-specific items. The costs are clearly separable from our normal business operations and are not expected to recur once the pandemic subsides.
5    "Transaction fees" represent certain acquisition related expenses associated with the UTXL and ACT acquisitions, consisting of legal and professional fees and are included in "Miscellaneous operating expenses" in the condensed consolidated statements of comprehensive income.
6    "Write-off of deferred debt issuance costs" was incurred from replacing the 2017 Debt Agreement with the 2021 Debt Agreement.

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 cash capital expenditures, from the aforementioned projectsincluding net cash capital expenditures of ACT, will be in the range of $450.0 $500.0$470.0 million for the full-year 2021. We believeThis is an update from our previously-disclosed range of $500.0 – $550.0 million for full-year 2021, as we have ample flexibility with our trade cycle and purchase agreements to alter our current plans if economic or other conditions warrant.received less revenue equipment than ordered during the year.
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 2021 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 2021 Revolver will be sufficient to fund our expected capital expenditures for at least the next twelve months.
Principal and Interest Payments — As of March 31,September 30, 2021, we had debt, accounts receivable securitization, and finance lease obligations of $825.5 million,$2.1 billion, 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 September 30, 2021, we paid $95.0 million on the 2021 Revolver.
Letters of Credit — Pursuant to the terms of the 20172021 Debt Agreement and the 20182021 RSA, our lenders may issue standby letters of credit on our behalf. When we have letters of credit outstanding, the availability under the 2021 Revolver or 20182021 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 March 31,September 30, 2021, the Company had $196.3 million remaining under the 2020 Knight-Swift Share Repurchase Plan. Additional details are discussed in Note 1113 in Part I, Item 1 of this Quarterly Report.
Working Capital
We had a working capital surplus of $15.3$551.9 million as of March 31,September 30, 2021 and $83.7 million as of December 31, 2020. Our working capital surplusThe favorable change was attributable to the refinance of our accounts receivable securitization in April 2021, as well as acquired receivables, cash and prepaids from the ACT Acquisition.

Net Cash Provided by Operating Activities
Comparison Between Year-to-Date September 30, 2021 and 2020 — The $162.5 million increase in net cash provided by operating activities was primarily due to a $253.7 million increase in operating income, due to the factors discussed in "Results of Operations — Consolidated Operating and Other Expenses" above. Additionally, in the first quarter of 2020, we paid a $93.4 million cash settlement associated with pre-2017 Merger legal matters that were previously accrued and disclosed. These items were partially offset by a $125.0 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 September 30, 2021 and 2020 — The $1.2 billion increase in net cash used in investing activities was primarily due to the $1.3 billion increase in net cash invested in acquisitions.
Net Cash Used in Financing Activities
Comparison Between Year-to-Date September 30, 2021 and 2020 — Net cash provided by financing activities increased by $1.1 billion, primarily due to $1.2 billion in proceeds from the 2021 Debt Agreement.

Comparison Between Quarter Ended March 31, 2021 and 2020 — The $150.8 million increase in net cash provided by operating activities was primarily due to less cash paid for legal settlements in the first quarter of 2021, as compared to the first quarter of 2020, when we paid $93.4 million associated with pre-2017 Merger legal matters that were previously accrued and disclosed by Swift. Net cash provided by operating activities was also favorably impacted by a $60.1 million increase in our operating income.
Net Cash Used in Investing Activities
Comparison Between Quarter Ended March 31, 2021 and 2020 — The $51.4 million decrease in net cash used in investing activities was primarily due to a $31.8 million decrease in net cash capital expenditures.
Net Cash Used in Financing Activities
Comparison Between Quarter Ended March 31, 2021 and 2020 — Net cash used in financing activities increased by $113.5 million, primarily due to a $110.0 million net increase in cash used for our Revolver, as we made net prepayments of $95.0 million during the first quarter of 2021, as compared to assuming net borrowings of $15.0 million during the first quarter of 2020.
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

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
We have exposure from variable interest rates, primarily related to our 20172021 Debt Agreement and 20182021 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%1.2% as of March 31,September 30, 2021) and fixed rate equipment lease financing. Assuming the level of borrowings as of March 31,September 30, 2021, a hypothetical one percentage point increase in interest rates would increase our annual interest expense by $6.1$18.3 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 decreasedincrease to $2.91$3.36 for the third quarter ended March 31,of 2021 from an average of $2.92$2.43 in the third quarter ended March 31,of 2020. The weekly average diesel price per gallon in the US increased to $3.16 for year-to-date September 30, 2021 from an average of $2.59 for year-to-date September 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
ThereExcept as set forth below, 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 March 31,September 30, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
During the quarter ended September 30, 2021, we completed the ACT Acquisition. We are in the process of evaluating the existing controls and procedures of ACT and integrating ACT into our internal controls over financial reporting. As permitted by SEC staff interpretative guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment for a period not to exceed one year from the date of acquisition, the scope of our assessment of our internal controls over financial reporting at September 30, 2021 does not include ACT.
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 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 1012 of the notes to our condensed consolidated financial statements, included in Part I, Item 1, of this Quarterly Report for the period ended March 31,September 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 and our Quarterly Report for the quarterly period ended June 30, 2021, in the sectionsections entitled "Item 1A. Risk Factors," describesdescribe some of the risks and uncertainties associated with our business. In addition to the risk factors set forth in these documents, we believe the following additional risks and uncertainties should be considered in evaluating our business and growth outlook:
The proposed new rule concerning mandatory COVID-19 vaccination of employees could have a material adverse effect on our business, financial condition, and results of operations.
In September 2021, President Biden announced a proposed new rule requiring all employers with at least 100 employees to ensure that their employees are fully vaccinated or require any employees who remain unvaccinated to produce a negative COVID-19 test result on at least a weekly basis before coming to work. The Department of Labor’s Occupational Safety and Health Administration ("OSHA") is drafting an emergency rule to carry out this mandate (the "Emergency Rule"), which is expected to take effect in the coming weeks. It is currently unclear whether the Emergency Rule will include an exception for professional truck drivers. When the Emergency Rule is implemented, it could, among other things, (i) cause our unvaccinated employees to go to smaller employers, not subject to the Emergency Rule, or leave us or the trucking industry, especially our unvaccinated drivers, (ii) result in logistical issues, increased expenses, and operational issues from arranging for weekly tests of our unvaccinated employees, especially our unvaccinated drivers, (iii) result in increased costs for recruiting and retention of drivers, as well as the cost of weekly testing, and (iv) result in decreased revenue if we are unable to recruit and retain new drivers due to the Emergency Rule. It is expected that a vaccination mandate that applies to drivers would significantly reduce the pool of available drivers to us and our industry, which would further impact the extreme shortage of available drivers. Furthermore, the actions by certain states may conflict with the Emergency Rule, causing further issues with compliance. Accordingly, the Emergency Rule, when implemented, could have a material adverse effect on our business, financial condition, and results of operations.
Difficulty in obtaining materials, equipment, goods and services from our vendors and suppliers could adversely affect our business.
We are dependent upon our suppliers for certain products and materials, including our tractors, trailers and chassis. If we fail to maintain favorable relationships with our vendors and suppliers, or if our vendors and suppliers are unable to provide the products and materials we need or undergo financial hardship, we could experience difficulty in obtaining needed goods and services because of production interruptions, limited material availability or other reasons, or we may not be able to obtain favorable pricing or other terms. Currently, tractor and trailer manufacturers are experiencing significant shortages of semiconductor chips and other component parts and supplies, forcing many manufacturers to curtail or suspend their production, which has led to a lower supply of tractors and trailers, higher prices, and lengthened trade cycles, which could have a material adverse effect on our business, financial condition, and results of operations, particularly our maintenance expense and driver retention.
