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 year-to-date period June 30, 2025, the Company operated an average of 21,610 tractors (comprised of 19,578 company tractors and 2,032 independent contractor tractors) and 89,826 trailers within the Truckload segment and leasing activities within the All Other Segments. The LTL segment operated an average of 4,108 tractors and 10,969 trailers. Additionally, the Intermodal segment operated an average of 612 tractors and 12,544 intermodal containers. As of June 30, 2025, the Company's four reportable segments were Truckload, LTL, 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 2024 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 the LTL operations of DHE prior to its acquisition by the Company on July 30, 2024 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's current and prior period results may not be meaningful.

Changes in Presentation

Consolidated Statements of Cash Flows — Beginning in the fourth quarter of 2024, the Company presents gross borrowings on its revolving lines of credit and gross repayments on its revolving lines of credit as separate items. Prior period amounts have been reclassified to align with the current period presentation.

Seasonality

In the full 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.

Note 3 — Acquisitions and Investments

DHE

On July 30, 2024, the Company, through a wholly owned subsidiary, acquired the operating assets and assumed certain liabilities of the regional less-than-truckload division of Dependable Highway Express, Inc. based in Los Angeles, California.

The total purchase price consideration of $185.0 million, including net working capital adjustments, was funded through borrowing on the 2021 Revolver on the transaction date. At closing, $1.5 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations. As of June 30, 2025, $0.5 million remains in escrow and is subject to further adjustments.

The goodwill recognized represents expected synergies from combining the operations of DHE 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.

Purchase Price Allocation

The purchase price allocation for DHE is preliminary and has been allocated based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date, and among other things may be 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 applicable. As the Company obtains more information, the preliminary purchase price allocations disclosed below are subject to change. Any future adjustments to the preliminary purchase price allocations, 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.

Note 4 — Income Taxes

Effective Tax Rate — The effective tax rates for the quarters ended June 30, 2025 and June 30, 2024 were 29.2% and 37.2%, respectively. The effective tax rates for the year-to-date periods ended June 30, 2025 and 2024 were 27.5% and 32.4%, respectively. The current quarter effective tax rate was primarily impacted by an increase in pre-tax income.

Valuation Allowance — Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. As of June 30, 2025 and December 31, 2024, the Company has $11.5 million and $11.1 million, respectively in valuation allowances associated with state operating loss carryforwards which may not be utilized in the future.

Interest and Penalties — The Company did not have accrued interest and penalties related to unrecognized tax benefits as of June 30, 2025 and December 31, 2024.

Tax Examinations — Certain of the Company's subsidiaries are currently under examination by various state jurisdictions for tax years ranging from 2019 to 2022. At the completion of these examinations, management does not expect any adjustments which would have a material impact on the Company's effective tax rate. Years subsequent to 2019 remain subject to examination.

Note 5 — Accounts Receivable Securitization

On October 23, 2023, the Company entered into the 2023 RSA, which further amended the 2022 RSA. The 2023 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, 2025, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

The 2023 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, 2025. 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.

The following table summarizes the key terms of the 2023 RSA (dollars in thousands):

	2023 RSA
	(Dollars in thousands)
Effective date	October 23, 2023
Final maturity date	October 1, 2025
Borrowing capacity	$575,000
Accordion option 1	$100,000
Unused commitment fee rate 2	20 to 40 basis points
Program fees on outstanding balances 3	one month SOFR + credit spread adjustment 10 basis points + 82.5 basis points

1The accordion option increases the maximum borrowing capacity, subject to participation of the purchasers.

2The commitment fee rates are based on the percentage of the maximum borrowing capacity utilized.

3As identified within the 2023 RSA, the lender can trigger an amendment by identifying and deciding upon a replacement index for SOFR.

Availability under the 2023 RSA is calculated as follows:

	June 30, 2025		December 31, 2024
	(In thousands)
Borrowing base, based on eligible receivables	$	455,200	$	500,700
Less: outstanding borrowings 1	(439,200)		(459,200)
Less: outstanding letters of credit	(15,730)		(27,167)
Availability under accounts receivable securitization facilities	$	270	$	14,333

1Outstanding borrowings are included in "Accounts receivable securitization - current portion" in the condensed consolidated balance sheets and are offset by deferred loan costs of $0.1 million and $0.2 million as of June 30, 2025 and December 31, 2024, respectively. Interest accrued on the aggregate principal balance at a rate of 5.3% and 5.5% as of June 30, 2025 and December 31, 2024, respectively.

The 2021 Debt Agreement included the 2021 Term Loan A-1 which was paid off on December 3, 2022. On August 6, 2024, the Company entered into the 2024 Amendment which, among other things, extended the maturity of the Company's 2021 Term Loan A-2 from September 3, 2024 to September 3, 2026, increased the size of the 2021 Term Loan A-2 from $200 million to $350 million, aligned the applicable margin for the 2021 Term Loan A-2 with that of the rest of the credit facility, transitioned the reference rate for the credit facility from BSBY to SOFR, and made other conforming changes. The following table presents the key terms of the 2021 Debt Agreement as amended by the 2024 Amendment:

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 June 30, 2025, the Company was in compliance with the covenants under the 2021 Debt Agreement.

Note 7 — Defined Benefit Pension Plan

Net periodic pension income and benefits paid during the quarter ended June 30, 2025 and 2024 were immaterial.

Assumptions

A weighted-average discount rate of 5.24% was used to determine benefit obligations as of June 30, 2025.

The following weighted-average assumptions were used to determine net periodic pension cost:

	Quarter Ended June 30,				Year-to-Date June 30,
	2025		2024		2025		2024
Discount rate	5.26	%	5.03	%	5.39	%	4.86	%
Expected long-term rate of return on pension plan assets	5.00	%	6.00	%	5.00	%	6.00	%

Refer to Note 12 for additional information regarding fair value measurements of the Company's investments.

Note 8 — Purchase Commitments

As of June 30, 2025, the Company had outstanding commitments to purchase revenue equipment of $416.4 million in the remainder of 2025 ($366.1 million of which were tractor commitments), and none thereafter. These purchases may be financed through any combination of finance leases, operating leases, debt, proceeds from sales of existing equipment, and cash flows from operations.

As of June 30, 2025, the Company had outstanding commitments to purchase facilities and non-revenue equipment of $89.3 million in the remainder of 2025, $75.5 million from 2026 through 2027, $8.6 million from 2028 through 2029, and none thereafter. Factors such as costs and opportunities for future terminal expansions may change the amount of such expenditures.

Note 9 — Contingencies and Legal Proceedings

Legal Proceedings

The Company is party to certain legal proceedings incidental to its business. The majority of these claims relate to bodily injury, property damage, cargo and workers' compensation incurred in the transportation of freight, as well as certain class action litigation related to personnel and employment matters. We record a liability when we believe that it is probable that a loss has been incurred and the amount can be reasonably estimated.

Based on our present knowledge of the facts and, in certain cases, advice of outside counsel, management believes the resolution of open claims and pending litigation, taking into account existing reserves, is not likely to have a materially adverse impact on our condensed consolidated financial statements. However, any future claims or adverse developments in existing claims could impact this analysis. 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. Cash flows or results of operations could be materially affected in any particular period by the resolution of one or more of these contingencies.

The Company has made accruals with respect to its legal matters where appropriate, as well as legal fees which are included in "Accrued liabilities" in the condensed consolidated balance sheets. The Company has recorded an aggregate accrual of approximately $4.9 million, relating to the Company's outstanding legal proceedings as of June 30, 2025.

Third-Party Carrier Insurance Commitments

During 2024, the Company finalized the terms for transactions with the insurer under the third-party reinsurance agreement covering auto liability associated with the Company's third-party carrier insurance business. The first agreement finalized on February 14, 2024, effectively transferred $161.1 million in third-party auto liability insurance claim liabilities to the insurer for policy periods from October 1, 2020 through March 31, 2023. The transfer of these liabilities was funded by conveying to the insurer the corresponding restricted cash held in trust for payment of the third-party insurance claims. A second agreement finalized on December 28, 2024, effectively transferred the remaining $77.2 million in third-party auto liability insurance claim liabilities to the insurer for the policy period of April 1, 2023 through March 31, 2024. The transfer of these liabilities will be funded by conveying to the insurer the corresponding restricted cash held in trust for payment of the third-party insurance claims in installments from December 30, 2024 through October 1, 2025. The Company remains responsible for potential additional premiums and aggregate reinsurance amounts above agreed loss development thresholds depending upon the ultimate development of claims. The maximum potential additional premium under each transfer agreement is $14.0 million. During the quarter ended June 30, 2025, the Company recorded a loss contingency of $2.8 million related to estimated additional premiums as certain claims in the first transfer transaction have reached amounts above the agreed loss development thresholds noted above. This is recorded in "Insurance and claims" in the Company's condensed consolidated statements of comprehensive income.

Note 10 — Share Repurchase Plans

In April 2022, the Board approved the repurchase of up to $350.0 million of the Company's outstanding common stock (the "2022 Knight-Swift Share Repurchase Plan").

The Company made no share repurchases during the quarter and year-to-date periods ended June 30, 2025 and 2024.no

As of June 30, 2025 and December 31, 2024, the Company had $200.0 million remaining under the 2022 Knight-Swift Share Repurchase Plan.

Note 11 — Weighted Average Shares Outstanding

Earnings per share, basic and diluted, as presented in the condensed consolidated statements of comprehensive income, are calculated by dividing net income attributable to Knight-Swift by the respective weighted average common shares outstanding during the period.

The following table reconciles basic weighted average shares outstanding to diluted weighted average shares outstanding:

	Quarter Ended June 30,		Year-to-Date June 30,
	2025	2024	2025	2024
	(In thousands)
Basic weighted average common shares outstanding	162,131	161,689	162,052	161,598
Dilutive effect of equity awards	410	422	445	491
Diluted weighted average common shares outstanding	162,541	162,111	162,497	162,089
Anti-dilutive shares excluded from earnings per diluted share 1	888	525	697	378

1    Shares were excluded from the dilutive-effect calculation because the outstanding awards' exercise prices were greater than the average market price of the Company's common stock for the periods presented.

Recurring Fair Value Measurements (Assets) — As of June 30, 2025 and December 31, 2024, there were no major categories of assets estimated at fair value that were measured on a recurring basis.

Recurring Fair Value Measurements (Liabilities) — The following table depicts the level in the fair value hierarchy of the inputs used to estimate the fair value of liabilities measured on a recurring basis as of June 30, 2025 and December 31, 2024:

1The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations.

The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions:

	2025		2024
Beginning balance	$	137,490	$	174,966
Change in fair value of contingent consideration (a)	—		(36,617)
Settlement of contingent consideration (b)	—		(859)
Ending balance	$	137,490	$	137,490

(a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. The Company completes this valuation every six months with the next valuation being completed on December 31,2025.

As of June 30, 2025, the Company used volatility rates of 40.0% and 47.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of June 30, 2025 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2024 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

Based on the Company’s ongoing assessment of the fair value of the contingent consideration the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million during 2024 which was recognized as a gain and is recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income.

Executive Summary

Company Overview

Knight-Swift Transportation Holdings Inc. is one of North America's largest and most diversified freight transportation companies, providing multiple full truckload, LTL, intermodal, and other complementary services. Our objective is to operate our business with industry-leading margins and continued organic growth and growth through acquisitions while providing safe, high-quality, cost-effective solutions for our customers. Knight-Swift uses a nationwide network of business units and terminals in the US and Mexico to serve customers throughout North America. In addition to operating the country's largest truckload fleet, Knight-Swift also contracts with third-party equipment providers to provide a broad range of transportation services to our customers while creating quality driving jobs for our driving associates and successful business opportunities for independent contractors. Our four reportable segments are Truckload, LTL, Logistics, and Intermodal. Additionally, we have various non-reportable segments.

Key Financial Highlights — Year-to-Date June 30, 2025

Consolidated operating income increased 65.8% to $139.3 million during the first half of 2025, as compared to the same period last year. Net income attributable to Knight-Swift increased 267.3% to $64.9 million.

•Truckload — 96.3% operating ratio during the first half of 2025. The Adjusted Operating Ratio1 was 95.1%, with a 3.4% year-over-year decrease in revenue, excluding fuel surcharge and intersegment transactions. Cost-reduction efforts led to a 1.3% reduction in our Adjusted Operating Expenses per mile for the first half of 2025, compared to the first half of 2024.

•LTL — 95.8% operating ratio during the first half of 2025. The Adjusted Operating Ratio1 deteriorated 570 basis points year-over-year to 93.6%, due to start-up costs and early-stage operations at recently opened facilities as well as some lingering costs from the integration of the DHE Acquisition. We opened ten new locations during the first half of 2025, as we continue to invest in our network.

•Logistics — 96.0% operating ratio during the first half of 2025. The Adjusted Operating Ratio1 was 95.2% with a gross margin of 18.5%. Revenue increased 4.4% year-over-year. Revenue per load increased 11.0% and was partially offset by a 5.8% decline in load count.

•Intermodal — 103.0% operating ratio during the first half of 2025, as revenue per load declined 1.3% year-over-year and load count decreased 4.3%.

•All Other Segments — Operating income increased to $12.8 million during the first half of 2025 from a $16.6 million operating loss during the comparable period of 2024, largely as a result of our warehousing business and leasing businesses and reflects improvement from the prior year period, which had included a $19.5 million operating loss for the third-party insurance business we exited during the first quarter of 2024.

•Liquidity and Capital — During the first half of 2025, we generated $325.9 million in operating cash flows and Free Cash Flow1 of $153.7 million. We paid down $81.5 million in finance lease liabilities, $75.4 million in operating lease liabilities, and had $45.0 million of net borrowings on our 2021 Revolver and 2023 RSA. As of June 30, 2025, we had a balance of $216.3 million in unrestricted cash and cash equivalents, $2.6 billion face value outstanding debt, net of unrestricted cash, and $7.1 billion of stockholders' equity. We do not foresee material liquidity constraints or any issues with our ongoing ability to meet our debt covenants. See discussion under "Liquidity and Capital Resources" for additional information.

Market Trends and Company Outlook

Market Trends

The second quarter saw unprecedented trade actions, which brought a range of responses by shippers and volatility in freight flows that differed meaningfully from normal patterns and typical seasonal trends in the Truckload market. This called for agility from our businesses, and our people responded, demonstrating the flexibility of our over-the-road capacity and network in order to mitigate pressure on miles and earnings.

While the import "cliff" that many anticipated did not prove to be as stark, there was a general softness in freight demand for most of the quarter, especially on the West coast. We did experience a mild lift in freight opportunities and projects near the end of the quarter but short of a normal seasonal build in freight volumes we typically see in a second quarter. While we continue to drive cost out of our businesses, we are careful not to sacrifice the competitive advantage we have through our industry-leading scale and the flexibility our over-the-road model provides, allowing us to deliver distinctive value to our customers.

We are continuing to grow our LTL network, customer base, and volumes, and we are committed to doing this while maintaining strong service levels. We are encouraged to see customers responding to our service offering, awarding us robust growth at a time when industry volumes remain under pressure. At the same time, the costs of expansion and integration, and our efforts to ramp staffing levels and fleet assets in anticipation of further growth are putting pressure on margins. We have multiple initiatives underway to accelerate the normalization of our operational fundamentals and the regaining of efficiencies in our cost performance even as our network and freight portfolio grow rapidly.

The fluid policy environment makes forecasting even more difficult than normal. We are staying close with our customers as the situation unfolds, delivering solid service and bringing our capacity and creativity to bear in responding to disruptions created by the shifting landscape. Changes in trade policy can create the need for shippers to react quickly in managing inventory levels, which could benefit the fast, flexible nature of our truckload service. As we begin to navigate the third quarter, we are in early discussions with a few customers regarding potential projects during peak season. It is too early to know if these discussions will materialize into additional business, but these types of conversations provide encouragement that one-way capacity is becoming less plentiful and more valuable when it can be provided with scale. We cannot say when the freight market will finally turn, but we are confident that we are well-positioned to make the most of the opportunities that the next cycle will bring given our larger Truckload business, our heavy mix of one-way truckload service, our growing LTL business, our agile and efficient Logistics business which complements our asset model, and the progress we continue to make structurally cutting cost out of our organization.

Company Outlook

Our Company outlook for the third quarter of 2025 includes the following:

Truckload

•Truckload Segment revenue up low single-digit percent sequentially with operating margins slightly improved sequentially,

•Revenue per loaded mile recovers slightly sequentially as freight mix normalizes,

•Tractor count and utilization largely stable sequentially.

LTL

•LTL Segment revenue, excluding fuel surcharge, growth between 20% - 25% year-over-year in third quarter as we lap the DHE acquisition in July,

•Adjusted Operating Ratio improves 100 - 200 basis points sequentially as cost initiatives and operating leverage overcome normal seasonal degradation.

Logistics

•Logistics Segment revenue and Adjusted Operating Ratio fairly stable sequentially.

30

Table of Contents Glossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

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

Intermodal

•Intermodal Segment load count improves high single-digit percent sequentially,

•Operating loss improves sequentially driven by cost initiatives and volume leverage.

All Other

•All Other Segment operating income, before including the $11.7 million quarterly intangible asset amortization, approximately $15 million to $20 million in third quarter, with a fourth quarter sequential step-down similar to prior year trends.

Additional

•Gain on sale to be in the range of $18 million to $23 million in third quarter,

•Net interest expense fairly stable sequentially in third quarter,

•Net cash capital expenditures for the full year 2025 expected range of $525 million - $575 million,

•Expected effective tax rate on adjusted income before taxes of approximately 27% to 28% for third quarter.

In addition to the above, we expect the Truckload segment will continue to pursue opportunities, as we continue to implement a decentralized operating model within our new U.S. Xpress locations, and the Logistics segment will continue to provide value to our customers through our power-only and traditional brokerage service offerings. With our mid-2024 acquisition of DHE and the continued organic expansion of our ACT, MME, and DHE brands, we expect additional yield and revenue opportunities from our growing super-regional LTL transportation network. The pace of our LTL facility expansion will be lower in 2025 than in 2024 as we focus on ongoing bid activities that we believe will provide further opportunities to grow shipment volumes and improve efficiencies in our LTL segment. The Intermodal segment continues to build out its network that aligns with our new rail partners as we pursue a more diversified portfolio of customers. Our All Other Segments are further expanding to complement our other service offerings.

We anticipate that depreciation and amortization expense will increase, as a percentage of revenue, excluding truckload and LTL fuel surcharge, as we intend to purchase, rather than enter into operating leases, for a majority of our revenue equipment or terminal improvements during 2025. With significant tightening in the insurance markets, we may also experience changes in premiums, retention limits, and excess coverage limits in the remainder of 2025. While fuel expense is generally offset by fuel surcharge revenue, our fuel expense, net of truckload and LTL fuel surcharge revenue, may increase in the future, particularly during periods of sharply rising fuel prices. In periods of declining prices the opposite is true. Overall, we remain committed to long-term profitability as we continue to leverage opportunities across the Knight-Swift brands, and efficiently deploy our assets, while maintaining a relentless focus on cost control. This includes seeking acquisition opportunities to improve earnings, gain customers, and reach more professional drivers, as illustrated by the acquisition of U.S. Xpress and our intention to further expand the geographic footprint of our LTL network, as illustrated by the DHE Acquisition.

Results of Operations — Summary

Note: The reported results do not include the LTL operations of DHE prior to its acquisition by the Company on July 30, 2024 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's current and prior period results may not be meaningful.

Operating Results: Second Quarter 2025 compared to Second Quarter 2024

The $13.9 million increase in net income attributable to Knight-Swift to $34.2 million during the second quarter of 2025 from $20.3 million during the same period last year includes the following:

•Contributor — $21.9 million increase in operating income within our Truckload segment primarily due to a 2.6% year-over-year reduction in our Adjusted Operating Expenses per mile.

•Contributor — $8.3 million increase in other income, net, primarily due to current quarter income within our portfolio of investments.

•Contributor — $2.9 million increase in operating income within the All Other Segments, driven by a 9.0% increase in revenue primarily driven by our warehousing and leasing businesses.

•Contributor — $0.8 million increase in operating income within our Logistics segment due to a 100 basis point improvement in gross margin percentage.

•Offset — $14.7 million decrease in operating income within our LTL segment primarily due to start-up costs and early-stage operations at the recently opened facilities.

•Offset — $2.2 million increase in consolidated income tax expense, primarily due to increase in pretax income. Our effective tax rate for the second quarter of 2025 was 29.2%, compared to 37.2% for the second quarter of 2024.

•Offset — $1.7 million increase in operating loss within our Intermodal segment, driven by a 12.4% decrease in load count, and a 1.6% decrease in revenue per load.

•Offset — $0.4 million increase in consolidated interest expense primarily driven by higher overall debt balances.

Operating Results: First Half 2025 compared to First Half 2024

The $47.2 million increase in net income attributable to Knight-Swift to $64.9 million during the first half of 2025 from $17.7 million during the same period last year includes the following:

•Contributor — $43.4 million increase in operating income within our Truckload segment primarily due to a 1.3% year-over-year reduction in our Adjusted Operating Expenses per mile.

•Contributor — $3.5 million increase in operating income within our Logistics segment due to a 11.0% increase in revenue per load.

•Contributor — $1.4 million decrease in operating loss within our Intermodal segment.

•Contributor — $29.3 million increase in operating income within the All Other Segments, largely as a result of exiting the third-party insurance business at the end of the first quarter of 2024.

•Contributor — $10.3 million increase in other income, net, primarily due to income within our portfolio of investments.

•Contributor — $0.6 million decrease in consolidated interest expense primarily driven by lower interest rates, partially offset by higher overall debt balances.

•Offset — $22.3 million decrease in operating income within our LTL segment primarily due to start-up costs and early-stage operations at the recently opened facilities.

•Offset — $16.2 million increase in consolidated income tax expense, primarily due to increase in pretax income. Our effective tax rate for the first half of 2025 was 27.5%, compared to 32.4% for the first half of 2024.

Revenue

•Our truckload services include irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border transportation of various products, goods, and materials for our diverse customer base with approximately 15,400 irregular route and 5,900 dedicated tractors.

•Our LTL business, which was initially established in 2021 through the ACT Acquisition and later the MME and DHE acquisitions, provides our customers with super-regional LTL transportation service through our growing network of approximately 180 facilities and a door count of approximately 6,600. Our LTL segment operates approximately 4,200 tractors and approximately 11,000 trailers, including equipment used for dedicated and other businesses. The LTL segment also provides national coverage to our customers by utilizing partner carriers for areas outside of our direct network.

•Our Logistics and Intermodal segments provide a multitude of shipping solutions, including additional sources of truckload capacity and alternative transportation modes, by utilizing our vast network of third-party capacity providers and rail providers, as well as certain logistics and freight management services. We offer power-only services through our Logistics segment leveraging our fleet of nearly 90,000 trailers.

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

•In addition to the revenues earned from our customers for the trucking and non-trucking services discussed above, we also earn fuel surcharge revenue from our customers through our fuel surcharge programs, which serve to recover a majority of our fuel costs. This generally applies only to loaded miles for our Truckload and LTL segments and typically does not offset non-paid empty miles, idle time, 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 Truckload and LTL segments.

Expenses

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

Segment Review

Truckload Segment

We generate revenue in the Truckload segment primarily through irregular route, dedicated, refrigerated, expedited, flatbed, and cross-border service operations across our brands. Generally, we are paid a predetermined rate per mile or per load for our truckload services. Additional revenues are generated by charging for tractor and trailer detention, loading and unloading activities, dedicated services, 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 Truckload segment are rate per mile from our customers, the percentage of miles for which we are compensated, and the number of loaded miles we generate with our equipment.

The most significant expenses in the Truckload segment are primarily variable and include fuel and fuel taxes, driving associate-related expenses (such as wages, benefits, training, and recruitment), and costs associated with independent contractors primarily included in "Purchased transportation" in the 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 Truckload segment are depreciation and rent expense from tractors, trailers, 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, 2025 and 2024 — Truckload segment revenue, excluding fuel surcharge and intersegment transactions, declined 2.7% year-over-year, driven by a 2.8% decrease in loaded miles. Revenue per loaded mile, excluding fuel surcharge and intersegment transactions, was flat year-over-year but down 1.4% from the first quarter of 2025 as a result of mix changes and spot market weakness given the lull in import-driven demand during the quarter. The second quarter Adjusted Operating Ratio improved 260 basis points year-over-year to 94.6%, reflecting improvements of 300 basis points for U.S. Xpress and 250 basis points for our legacy trucking businesses. Miles per tractor improved 4.0% year-over-year as a result of our efforts to drive productivity and reduce underutilized assets. Our cost-reduction efforts led to a 2.6% year-over-year reduction in our Adjusted Operating Expenses per mile as we continue to make tangible progress improving our cost structure. We are focused on disciplined pricing, cost control, and quality service that we expect will position our business to continue to respond to volatile market conditions.

Comparison Between Year-to-Date June 30, 2025 and 2024 — Truckload segment revenue, excluding fuel surcharge and intersegment transactions declined 3.4% year-over-year, driven by a 4.1% decrease in loaded miles. Adjusted Operating Ratio improved 220 basis points during the first half of 2025 to 95.1%, reflecting improvements of 200 basis points for U.S. Xpress and 220 basis points for our legacy trucking businesses. Miles per tractor improved 2.4% year-over-year as a result of our efforts to drive productivity and reduce underutilized assets. Our cost-reduction efforts led to a 1.3% year-over-year reduction in our Adjusted Operating Expenses per mile.

LTL Segment

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

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

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

Comparison Between the Quarters Ended June 30, 2025 and 2024 — Our LTL segment grew revenue, excluding fuel surcharge, 28.4% as shipments per day increased 21.7% year-over-year, which includes the acquisition of DHE on July 30, 2024. Revenue per hundredweight, excluding fuel surcharge, increased 9.9%, while revenue per shipment, excluding fuel surcharge, increased by 7.1%. Weight per shipment decreased 2.6% year-over-year but was flat with the first quarter. Average length of haul continues to climb, rising 13.8% year-over-year and 4.2% sequentially, as we win new business across our expanding network. This segment produced a 93.1% Adjusted Operating Ratio during the second quarter, which was an improvement of 110 basis points from the first quarter of 2025. Adjusted Operating Income decreased 36.8% year-over-year due to the decline in operating margin primarily attributable to early-stage operations at our recently opened facilities as well as continued costs related to the integration of DHE. While the LTL segment continues to post strong growth in customers and freight volumes across the expanding network, we are taking actions to accelerate the realization of cost efficiencies and to better align our resources with shifting volumes and freight flows. We anticipate that progress on these initiatives will partially offset the normal seasonal pattern of operating margin degradation in the second half of the year.

During the second quarter, we opened three new service centers and replaced one more with a larger site, bringing our year-to-date growth in door count to 7.8% and our year-over-year growth in door count to 27.5%. We continue to expect our pace of facility expansion will be lower in 2025 than in 2024 and believe ongoing bid activities will provide further opportunities to grow shipment volume and improve efficiencies. Our focus for 2025 is to drive both revenue and margin expansion in the business. We continue to look for both organic and inorganic opportunities to geographically expand our footprint within the LTL market.

Comparison Between Year-to-Date June 30, 2025 and 2024 — Our LTL segment grew revenue, excluding fuel surcharge, 27.6% as shipments per day increased 22.9% during the first half of 2025, which includes the acquisition of DHE on July 30, 2024. Revenue per hundredweight, excluding fuel surcharge, increased 9.6%, while revenue per shipment, excluding fuel surcharge, increased by 6.8%, while weight per shipment decreased 2.6%. This segment produced a 93.6% Adjusted Operating Ratio during the first half of 2025, and Adjusted Operating Income decreased 32.9% when compared to the first half of 2024, due to the decline in operating margin primarily attributable to early-stage operations at our recently opened facilities as well as continued costs related to the integration of DHE.

Logistics Segment

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

The most significant expense in the Logistics segment is purchased transportation that we pay to third-party capacity providers, which is primarily a variable cost and is included in "Purchased transportation" in the 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.

Comparison Between the Quarters Ended June 30, 2025 and 2024 — The Logistics segment Adjusted Operating Ratio was 94.8%, with a gross margin of 18.9% in the second quarter of 2025. Revenue decreased 2.6% year-over-year, driven by a 11.7% decline in load count, largely offset by a 10.6% increase in revenue per load. We remain disciplined on price and diligent in carrier qualification to provide value to customers while maintaining profitability. We continue to leverage our power-only capabilities to complement our asset business, build a broader and more diversified freight portfolio, and to enhance the returns on our capital assets.

Comparison Between Year-to-Date June 30, 2025 and 2024 — The Logistics segment Adjusted Operating Ratio was 95.2%, with a gross margin of 18.5% in the first half of 2025. Revenue increased 4.4% year-over-year, driven by an 11.0% increase in revenue per load, partially offset by a 5.8% decline in load count.

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. While rail pricing is determined on an annual basis, purchased transportation varies as it relates to rail capacity, freight demand, and customer shipping needs. The main fixed costs in the Intermodal segment are depreciation of our company tractors related to drayage, containers, and chassis, as well as non-driver employee compensation and benefits.

Includes 564 and 554 company-owned tractors for the year-to-date periods ended June 30, 2025 and 2024, respectively.

Comparison Between the Quarters Ended June 30, 2025 and 2024 — The Intermodal segment operating ratio increased 230 basis points year-over-year to 104.1%, driven by a 13.8% decline in revenue, partially offset by reductions in cost and improvements in network balance. The revenue decrease was the result of a 12.4% decrease in load count and a 1.6% decline in revenue per load year-over-year. This segment was the most impacted by the decline in import volumes on the West coast, however, we expect load count to grow sequentially as a result of new customer awards and a return of normalized volumes of existing customers. During the quarter we converted to private chassis in five markets, which we expect will improve the cost structure of this business. We remain focused on creating a balanced network, reducing empty moves, and growing our load count with disciplined pricing.

Comparison Between Year-to-Date June 30, 2025 and 2024 — The Intermodal segment operated with a 103.0% operating ratio, while total revenue decreased 5.6% year-over-year to $175.2 million. The drop in revenue was driven by a 1.3% decline in revenue per load, and a 4.3% decline in load count when compared to the same period last year.

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 truckload and LTL fuel surcharge. Truckload and LTL fuel surcharge revenue can be volatile and is primarily dependent upon the cost of fuel, rather than operating expenses unrelated to fuel. Therefore, we believe that revenue, excluding truckload and LTL fuel surcharge is a better measure for analyzing many of our expenses and operating metrics.

Note: The reported results do not include the LTL operations of DHE prior to its acquisition by the Company on July 30, 2024 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's current and prior periods may not be meaningful.

	2025			2024			2025			2024			QTD 2024		YTD 2024
	(Dollars in thousands)												Increase (Decrease)
Salaries, wages, and benefits	$	754,582		$	691,878		$	1,476,241		$	1,384,785		9.1	%	6.6	%
% of total revenue	40.5		%	37.5		%	40.0		%	37.7		%	300	bps	230	bps
% of revenue, excluding truckload and LTL fuel surcharge	45.1		%	42.1		%	44.7		%	42.5		%	300	bps	220	bps

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

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

Comparison Between the Quarters Ended June 30, 2025 and 2024 — The $62.7 million increase in consolidated salaries, wages, and benefits for the second quarter of 2025, as compared to the second quarter of 2024, is primarily due to a $47.5 million increase in LTL wages as a result of service center expansion, the DHE Acquisition, and labor to support increased shipment count from expansion efforts. This was partially offset by a $3.3 million decrease in Truckload driving associate mileage pay primarily due to a 2.5% decrease in total miles driven by company driving associates in our Truckload segment.

Comparison Between Year-to-Date June 30, 2025 and 2024 — The $91.5 million increase in consolidated salaries, wages, and benefits for the first half of 2025, as compared to the first half of 2024, is primarily due to a $85.9 million increase in LTL wages as a result of service center expansion, the DHE Acquisition, and labor to support increased shipment count from expansion efforts. This was partially offset by a $5.7 million decrease in Truckload driving associate mileage pay primarily due to a 3.6% decrease in total miles driven by company driving associates in our Truckload segment.

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

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

Comparison Between Quarters Ended June 30, 2025 and 2024 — The $19.0 million decrease in consolidated fuel expense for the second quarter of 2025 is primarily driven by the 2.5% decrease in Truckload total miles driven by company driving associates and the decrease in the average weekly DOE fuel prices for the second quarter of 2025, as compared to the second quarter of 2024. This was partially offset by a 34.0% increase in LTL miles. Average weekly DOE fuel prices were $3.56 per gallon for the second quarter of 2025 and $3.85 per gallon for the second quarter of 2024.

Comparison Between Year-to-Date June 30, 2025 and 2024 — The $46.4 million decrease in consolidated fuel expense for the first half of 2025 is primarily driven by the 3.6% decrease in Truckload total miles driven by company driving associates and the decrease in the average weekly DOE fuel prices for the first half of 2025, as compared to the first half of 2024. This was partially offset by a 30.0% increase in LTL miles. Average weekly DOE fuel prices were $3.59 per gallon for the first half of 2025 and $3.91 per gallon for the first half of 2024.

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

Operations and maintenance expense remained relatively flat for the second quarter of 2025 and the first half of 2025, as compared to the same periods last year.

% of revenue, excluding truckload and LTL fuel surcharge	5.1		%	6.4		%	5.4		%	7.0		%	(130	bps)	(160	bps)

Insurance and claims expense consists of premiums for liability, physical damage, and cargo, and will vary based upon the frequency and severity of claims, our level of self-insurance, and premium expense. In recent years, insurance carriers have raised premiums for many businesses, including transportation companies, 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 and lower excess coverage limits, may cause increased volatility in our consolidated insurance and claims expense.

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

Comparison Between Quarters Ended June 30, 2025 and 2024 — Consolidated insurance and claims expense decreased by $20.2 million for the second quarter of 2025, as compared to the same period last year. This decrease was primarily due to a 2.5% decrease in total miles driven year-over-year, improvements within our current year experience as a result of lower frequency and severity of claims, and positive development within certain prior year losses.

Comparison Between Year-to-Date June 30, 2025 and 2024 — Consolidated insurance and claims expense decreased by $50.4 million for the first half of 2025, as compared to the same period last year primarily due to the Company exiting the third-party insurance business at the end of the first quarter of 2024. Additionally, the decrease was due to a 3.6% decrease in total miles driven year-over-year, improvements within our current year experience as a result of lower frequency and severity of claims, and positive development within certain prior year losses.

Operating taxes and licenses include state franchise taxes, state and federal highway use taxes, property taxes, vehicle license and registration fees, and 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.

Operating taxes and licenses expenses increased by $4.2 million for the second quarter of 2025 and $7.2 million for the first half of 2025, as compared to the same periods last year, primarily as a result of expanding our LTL network.

% of revenue, excluding truckload and LTL fuel surcharge	10.6		%	10.9		%	10.7		%	11.1		%	(30	bps)	(40	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. Depreciation can also be affected by the cost of used equipment that we sell or trade and the replacement of older used equipment. Management periodically reviews the condition, average age, and reasonableness of estimated useful lives and salvage values of our equipment and considers such factors in light of our experience with similar assets, used equipment market conditions, and prevailing industry practices.

Comparison Between Quarters Ended June 30, 2025 and 2024 — Consolidated depreciation and amortization of property and equipment decreased $2.3 million for the second quarter of 2025, as compared to the same period last year. This decrease is primarily due to decreases in tractor and trailer depreciation as a result of the decrease in tractor and trailer counts in our Truckload segment, partially offset by increases in equipment counts for our LTL segment.

Comparison Between Year-to-Date June 30, 2025 and 2024 — Consolidated depreciation and amortization of property and equipment decreased $6.7 million for the first half of 2025, as compared to the same period last year. This decrease is primarily due to decreases in tractor and trailer depreciation as a result of the decrease in tractor and trailer counts in our Truckload segment, partially offset by increases in equipment counts for our LTL segment.

Non-GAAP Financial Measures

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

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

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

2    Based on eligible receivables at June 30, 2025, our borrowing base for the 2023 RSA was $455.2 million, while outstanding borrowings were $439.2 million, along with $15.7 million in outstanding letters of credit, leaving $0.3 million available under the 2023 RSA. Refer to Note 5 in Part I, Item 1 of this Quarterly Report for more information regarding the 2023 RSA.

3    Restricted cash is primarily held by our captive insurance companies for claims payments. "Cash and cash equivalents – restricted" consists of $123.1 million included in "Cash and cash equivalents – restricted" on the condensed consolidated balance sheet held by Mohave and Red Rock for claims payments. The remaining $5.6 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 and expand our trailer fleet, expand our network of LTL service centers, and, to a lesser extent, fund upgrades to our terminals and technology in our various service offerings. In connection with our business strategy, we regularly evaluate acquisition and strategic partnership opportunities. We expect net cash capital expenditures will be in the range of $525 million - $575 million for full-year 2025, which is a reduction from our original range of $575 million - $625 million. Our expected net cash capital expenditures primarily represent replacements of existing tractors and trailers and investments in our terminal network, driver amenities, and technology, and excludes acquisitions. We believe we have ample flexibility in our trade cycle and purchase agreements to alter our current plans if economic and 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 2025 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. On July 8, 2025, the 2021 Revolver was replaced by the 2025 Revolver, which matures on July 8, 2030. As of July 8, 2025, there was $810.0 million available under the 2025 Revolver. Refer to Note 6 in Part I, Item 1 of this Quarterly Report for information regarding the 2021 Revolver and the 2025 Revolver."

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 2025 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, 2025, we had debt, accounts receivable securitization, and finance lease obligations of $2.8 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.

Letters of Credit — Our lenders may issue standby letters of credit on our behalf, certain of which reduce availability under our 2023 RSA and our revolving line of credit. As of June 30, 2025, we also had outstanding letters of credit of $197.1 million pursuant to a bilateral agreement which do not impact the availability of the 2021 Revolver and 2023 RSA. 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 Flow1 availability, debt levels, common stock prices, general economic and market conditions, as well as internal approval requirements, we may repurchase shares of our outstanding common stock. As of June 30, 2025, the Company had $200.0 million remaining under the 2022 Knight-Swift Share Repurchase Plan. Additional details regarding our share repurchase plans are discussed in Note 10 in Part I, Item 1 of this Quarterly Report.

Working Capital

We had a working capital deficit of $181.0 million as of June 30, 2025 and a working capital deficit of $258.0 million as of December 31, 2024. The deficit is primarily due to the classification of the 2023 RSA, maturing on October 1, 2025, as a current liability. We intend to refinance the 2023 RSA prior to its maturity.

Material Debt Agreements

As of June 30, 2025, we had $2.8 billion in material debt obligations at the following carrying values:

•$349.4 million: 2021 Term Loan A-2, due September 2026, net of $0.6 million in deferred loan costs

•$759.6 million: 2021 Term Loan A-3, due September 2026, net of $0.4 million in deferred loan costs

•$249.6 million: 2023 Term Loan, due September 2026, net of $0.4 million in deferred loan costs

•$297.0 million: 2021 Revolver, due September 2026

•$153.4 million: Revenue equipment installment notes

As of December 31, 2024, we had $2.9 billion in material debt obligations at the following carrying values:

•$349.1 million: 2021 Term Loan A-2, due September 2026, net of $0.9 million in deferred loan costs

•$779.4 million: 2021 Term Loan A-3, due September 2026, net of $0.6 million in deferred loan costs

Cash Flow Analysis

	Year-to-Date June 30,				Change
	2025		2024
	(In thousands)
Net cash provided by operating activities	$	325,929	$	310,700	$	15,229
Net cash used in investing activities	(189,617)		(258,841)		69,224
Net cash used in financing activities	(161,586)		(182,288)		20,702

Net Cash Provided by Operating Activities

Comparison Between Year-to-Date June 30, 2025 and 2024 — The $15.2 million increase in net cash provided by operating activities is primarily related to a $161.1 million cash payment made during year-to-date June 30, 2024 for an agreement to transfer certain outstanding insurance reserves. The increase in net cash provided by operating activities also included a $55.3 million increase in operating income for year-to-date June 30, 2025, and was partially offset by changes to our net working capital.

Note: Factors affecting the increase in operating income are discussed in "Results of Operations — Consolidated Operating and Other Expenses."

Net Cash Used in Investing Activities

Comparison Between Year-to-Date June 30, 2025 and 2024 — The $69.2 million decrease in net cash used in investing activities was primarily due to a $86.4 million decrease in net cash capital expenditures and was partially offset by a $10.4 million increase in cash used on the acquisitions of leased properties.

Net Cash Used in Financing Activities

Comparison Between Year-to-Date June 30, 2025 and 2024 — Net cash used in financing activities decreased by $20.7 million, primarily due to a $54.6 million decrease in net repayments of our 2023 RSA and a $12.0 million decrease in net repayments on our 2021 Revolver, partially offset by a $48.8 million increase in repayments on our finance leases and long-term debt.

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

Most of our operating expenses are inflation-sensitive, with inflation generally leading to increased costs of operations. Price increases in manufactured revenue equipment has impacted the cost for us to acquire new equipment. Cost increases have also impacted the cost of parts for equipment repairs and maintenance. The qualified driver shortage experienced by the trucking industry overall has had the effect of increasing compensation paid to our driving associates. We have also experienced inflation in insurance and claims cost related to health insurance and claims as well as auto liability insurance and claims. Prolonged periods of inflation have recently and could continue to cause interest rates, fuel, wages, and other costs to increase as well. Any of these factors could adversely affect our results of operations unless freight rates correspondingly increase.

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

There have been no material changes from the market risks discussed in the section entitled "Quantitative and Qualitative Disclosures About Market Risk" set forth in Part II, Item 7A of our 2024 Annual Report.

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, 2025, 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 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.

Introduction and Basis of Presentation

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 year-to-date period June 30, 2025, the Company operated an average of 21,610 tractors (comprised of 19,578 company tractors and 2,032 independent contractor tractors) and 89,826 trailers within the Truckload segment and leasing activities within the All Other Segments. The LTL segment operated an average of 4,108 tractors and 10,969 trailers. Additionally, the Intermodal segment operated an average of 612 tractors and 12,544 intermodal containers. As of June 30, 2025, the Company's four reportable segments were Truckload, LTL, 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 2024 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 the LTL operations of DHE prior to its acquisition by the Company on July 30, 2024 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's current and prior period results may not be meaningful.

Changes in Presentation

Consolidated Statements of Cash Flows — Beginning in the fourth quarter of 2024, the Company presents gross borrowings on its revolving lines of credit and gross repayments on its revolving lines of credit as separate items. Prior period amounts have been reclassified to align with the current period presentation.

Seasonality

In the full 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.

Acquisitions and Investments

Acquisitions and Investments

DHE

On July 30, 2024, the Company, through a wholly owned subsidiary, acquired the operating assets and assumed certain liabilities of the regional less-than-truckload division of Dependable Highway Express, Inc. based in Los Angeles, California.

The total purchase price consideration of $185.0 million, including net working capital adjustments, was funded through borrowing on the 2021 Revolver on the transaction date. At closing, $1.5 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations. As of June 30, 2025, $0.5 million remains in escrow and is subject to further adjustments.

The goodwill recognized represents expected synergies from combining the operations of DHE 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.

Purchase Price Allocation

The purchase price allocation for DHE is preliminary and has been allocated based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date, and among other things may be 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 applicable. As the Company obtains more information, the preliminary purchase price allocations disclosed below are subject to change. Any future adjustments to the preliminary purchase price allocations, 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.

Accounts Receivable Securitization

Accounts Receivable Securitization

On October 23, 2023, the Company entered into the 2023 RSA, which further amended the 2022 RSA. The 2023 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, 2025, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

The 2023 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, 2025. 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.

The following table summarizes the key terms of the 2023 RSA (dollars in thousands):

	2023 RSA

Unused commitment fee rate 2	20 to 40 basis points
Program fees on outstanding balances 3	one month SOFR + credit spread adjustment 10 basis points + 82.5 basis points

1The accordion option increases the maximum borrowing capacity, subject to participation of the purchasers.

2The commitment fee rates are based on the percentage of the maximum borrowing capacity utilized.

3As identified within the 2023 RSA, the lender can trigger an amendment by identifying and deciding upon a replacement index for SOFR.

Availability under the 2023 RSA is calculated as follows:

	June 30, 2025		December 31, 2024
	(In thousands)
Borrowing base, based on eligible receivables	$	455,200	$	500,700

Less: outstanding letters of credit	(15,730)		(27,167)
Availability under accounts receivable securitization facilities	$	270	$	14,333

1Outstanding borrowings are included in "Accounts receivable securitization - current portion" in the condensed consolidated balance sheets and are offset by deferred loan costs of $0.1 million and $0.2 million as of June 30, 2025 and December 31, 2024, respectively. Interest accrued on the aggregate principal balance at a rate of 5.3% and 5.5% as of June 30, 2025 and December 31, 2024, respectively.

Credit Agreements

2021 Debt Agreement — On September 3, 2021, the Company entered into the $2.3 billion 2021 Debt Agreement (an unsecured credit facility) with a group of banks, replacing the Company's prior debt agreements. The 2021 Debt Agreement included the 2021 Term Loan A-1 which was paid off on December 3, 2022. On August 6, 2024, the Company entered into the 2024 Amendment which, among other things, extended the maturity of the Company's 2021 Term Loan A-2 from September 3, 2024 to September 3, 2026, increased the size of the 2021 Term Loan A-2 from $200 million to $350 million, aligned the applicable margin for the 2021 Term Loan A-2 with that of the rest of the credit facility, transitioned the reference rate for the credit facility from BSBY to SOFR, and made other conforming changes. The following table presents the key terms of the 2021 Debt Agreement as amended by the 2024 Amendment:

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 June 30, 2025, 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 material domestic subsidiaries (other than its captive insurance subsidiaries, driving academy subsidiary, and bankruptcy-remote special purpose subsidiary).

2023 Term Loan — On June 22, 2023, the Company entered into the $250.0 million 2023 Term Loan (an unsecured credit facility) with a group of banks. The 2023 Term Loan matures on September 3, 2026. There are no scheduled principal payments due until maturity. The 2023 Term Loan contains terms similar to the 2021 Debt Agreement. The proceeds received from the 2023 Term Loan were used to pay fees, commissions and expenses in connection with the Company's acquisition of U.S. Xpress. The interest rate applicable to the 2023 Term Loan is subject to a leverage-based grid and as of June 30, 2025 is equal to SOFR plus the 0.1% SOFR credit spread adjustment plus 1.75%. As of June 30, 2025, interest accrued at 6.18% on the 2023 Term Loan.

2025 Debt Agreement — On July 8, 2025, the Company entered into a $2.5 billion unsecured credit facility with a group of banks (the "2025 Debt Agreement"), replacing the 2021 Debt Agreement and the 2023 Term Loan. The 2025 Debt Agreement includes the following facilities:

•$1.5 billion revolving line of credit (the "2025 Revolver"), $672.0 million of which was drawn upon the Closing Date, maturing July 8, 2030

Contingencies and Legal Proceedings

Contingencies and Legal Proceedings

Legal Proceedings

The Company is party to certain legal proceedings incidental to its business. The majority of these claims relate to bodily injury, property damage, cargo and workers' compensation incurred in the transportation of freight, as well as certain class action litigation related to personnel and employment matters. We record a liability when we believe that it is probable that a loss has been incurred and the amount can be reasonably estimated.

Based on our present knowledge of the facts and, in certain cases, advice of outside counsel, management believes the resolution of open claims and pending litigation, taking into account existing reserves, is not likely to have a materially adverse impact on our condensed consolidated financial statements. However, any future claims or adverse developments in existing claims could impact this analysis. 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. Cash flows or results of operations could be materially affected in any particular period by the resolution of one or more of these contingencies.

The Company has made accruals with respect to its legal matters where appropriate, as well as legal fees which are included in "Accrued liabilities" in the condensed consolidated balance sheets. The Company has recorded an aggregate accrual of approximately $4.9 million, relating to the Company's outstanding legal proceedings as of June 30, 2025.

Third-Party Carrier Insurance Commitments

During 2024, the Company finalized the terms for transactions with the insurer under the third-party reinsurance agreement covering auto liability associated with the Company's third-party carrier insurance business. The first agreement finalized on February 14, 2024, effectively transferred $161.1 million in third-party auto liability insurance claim liabilities to the insurer for policy periods from October 1, 2020 through March 31, 2023. The transfer of these liabilities was funded by conveying to the insurer the corresponding restricted cash held in trust for payment of the third-party insurance claims. A second agreement finalized on December 28, 2024, effectively transferred the remaining $77.2 million in third-party auto liability insurance claim liabilities to the insurer for the policy period of April 1, 2023 through March 31, 2024. The transfer of these liabilities will be funded by conveying to the insurer the corresponding restricted cash held in trust for payment of the third-party insurance claims in installments from December 30, 2024 through October 1, 2025. The Company remains responsible for potential additional premiums and aggregate reinsurance amounts above agreed loss development thresholds depending upon the ultimate development of claims. The maximum potential additional premium under each transfer agreement is $14.0 million. During the quarter ended June 30, 2025, the Company recorded a loss contingency of $2.8 million related to estimated additional premiums as certain claims in the first transfer transaction have reached amounts above the agreed loss development thresholds noted above. This is recorded in "Insurance and claims" in the Company's condensed consolidated statements of comprehensive income.

Recurring Fair Value Measurements (Assets) — As of June 30, 2025 and December 31, 2024, there were no major categories of assets estimated at fair value that were measured on a recurring basis.

Recurring Fair Value Measurements (Liabilities) — The following table depicts the level in the fair value hierarchy of the inputs used to estimate the fair value of liabilities measured on a recurring basis as of June 30, 2025 and December 31, 2024:

1The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations.

The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions:

	2025		2024
Beginning balance	$	137,490	$	174,966
Change in fair value of contingent consideration (a)	—		(36,617)
Settlement of contingent consideration (b)	—		(859)
Ending balance	$	137,490	$	137,490

(a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. The Company completes this valuation every six months with the next valuation being completed on December 31,2025.

As of June 30, 2025, the Company used volatility rates of 40.0% and 47.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of June 30, 2025 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2024 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

Based on the Company’s ongoing assessment of the fair value of the contingent consideration the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million during 2024 which was recognized as a gain and is recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income.

(b)The Company did not recognize any gains in the quarter and year-to-date periods ended June 30, 2025 and 2024.

Nonrecurring Fair Value Measurements (Liabilities) — As of June 30, 2025 and December 31, 2024, the Company had no major categories of liabilities estimated at fair value that were measured on a nonrecurring basis.

Gain on Sale of Operating Assets — Net gains on disposals, including disposals of property and equipment classified as assets held for sale, are reported in "Miscellaneous operating expenses" in the condensed consolidated statements of comprehensive income. The Company recorded net gains of:

•$11.7 million and $6.0 million for the quarters ended June 30, 2025 and 2024, respectively.

•$27.3 million and $12.6 million for the year-to-date periods ended June 30, 2025 and 2024, respectively.

Fair Value of Pension Plan Assets — The following table sets forth by level the fair value hierarchy of ACT's pension plan financial assets accounted for at fair value on a recurring basis. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. ACT's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and their placement within the fair value hierarchy levels.

1The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations.

The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions:

	2025		2024
Beginning balance	$	137,490	$	174,966
Change in fair value of contingent consideration (a)	—		(36,617)
Settlement of contingent consideration (b)	—		(859)
Ending balance	$	137,490	$	137,490

(a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. The Company completes this valuation every six months with the next valuation being completed on December 31,2025.

As of June 30, 2025, the Company used volatility rates of 40.0% and 47.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of June 30, 2025 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2024 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.

Based on the Company’s ongoing assessment of the fair value of the contingent consideration the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million during 2024 which was recognized as a gain and is recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income.

(b)The Company did not recognize any gains in the quarter and year-to-date periods ended June 30, 2025 and 2024.

2As of December 31, 2024, the call option has expired and the mandatorily redeemable contingent consideration is now in the put option period.

Unobservable Measurement Input, Uncertainty, Description							The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations.

[1] The contingent consideration is primarily related to the U.S. Xpress Acquisition.

[2] The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations. The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions: 20252024Beginning balance$137,490 $174,966  Change in fair value of contingent consideration (a) — (36,617) Settlement of contingent consideration (b) — (859)Ending balance$137,490 $137,490  (a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. The Company completes this valuation every six months with the next valuation being completed on December 31,2025. As of June 30, 2025, the Company used volatility rates of 40.0% and 47.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of June 30, 2025 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2024 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. Based on the Company’s ongoing assessment of the fair value of the contingent consideration the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million during 2024 which was recognized as a gain and is recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income. (b)The Company did not recognize any gains in the quarter and year-to-date periods ended June 30, 2025 and 2024.

[3] As of December 31, 2024, the call option has expired and the mandatorily redeemable contingent consideration is now in the put option period.

[5] Reflects the non-cash impairment related to the market value of a facility lease (within the Truckload segment).

[6] Reflects non-cash impairments related to certain real property (within the Truckload segment).

[7] Reflects the non-cash impairment of building improvements (within the Truckload segment and the All Other Segments).

Business Combination, Contingent Consideration, Liability, Measurement Input			0.057		0.057

[1] The Company measures contingent consideration liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are forecasted operating income and net income over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations. The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions: 20252024Beginning balance$137,490 $174,966  Change in fair value of contingent consideration (a) — (36,617) Settlement of contingent consideration (b) — (859)Ending balance$137,490 $137,490  (a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. The Company completes this valuation every six months with the next valuation being completed on December 31,2025. As of June 30, 2025, the Company used volatility rates of 40.0% and 47.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of June 30, 2025 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2024 the Company used a discount rate of 5.7%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. Based on the Company’s ongoing assessment of the fair value of the contingent consideration the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million during 2024 which was recognized as a gain and is recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income. (b)The Company did not recognize any gains in the quarter and year-to-date periods ended June 30, 2025 and 2024.
