NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

THREE MONTHS ENDED MARCH 31, 2024

(Unaudited)

(1) Consolidated Condensed Financial Statements

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial statements, and therefore do not include all information and disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, such statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary to fairly present our consolidated financial condition, results of operations and cash flows for the interim periods presented. The results of operations for any interim period do not necessarily indicate the results for the full year. The unaudited interim consolidated condensed financial statements should be read with reference to the consolidated financial statements and notes to consolidated financial statements in our 2023 Annual Report on Form 10-K.

(2) Earnings per Common Share

Basic and diluted earnings per common share were computed as follows:

Three Months

Ended March 31,

(In thousands, except per share amounts)

2024

2023

Numerator:

Net income

$ 9,646 $ 22,502

Denominator:

Basic earnings per common share - weighted-average shares

81,350 81,210

Effect of dilutive stock options

87 166

Diluted earnings per common share - weighted-average shares and assumed conversions

81,437 81,376

Basic earnings per common share

$ 0.12 $ 0.28

Diluted earnings per common share

$ 0.12 $ 0.28

Options totaling 524,900 and 122,000 equivalent shares for the three-month periods ended March 31, 2024 and 2023, respectively, were outstanding but were not included in the calculation of diluted earnings per share because including the options in the denominator would be antidilutive, or decrease the number of weighted-average shares, due to their exercise prices exceeding the average market price of the common shares, or because inclusion of average unrecognized compensation expense in the calculation would cause the options to be antidilutive.

Unvested performance unit awards totaling 82,788 and 49,560 equivalent shares for the three-month periods ended March 31, 2024 and 2023, respectively, were considered outstanding but were not included in the calculation of diluted earnings per share because inclusion of average unrecognized compensation expense in the calculation would cause the performance units to be antidilutive.

(3) Long-Term Debt

In August 2022, we entered into a credit agreement that provides for an unsecured committed credit facility with an aggregate principal amount of $30.0 million which matures in August 2027. The credit agreement amends, restates and continues in its entirety our previous credit agreement, as amended. At March 31, 2024, there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $20.7 million and remaining borrowing availability of $9.3 million. At December 31, 2023, there was also no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit of $20.7 million on the facility. This facility bears interest at a variable rate based on the Term SOFR Rate plus applicable margins. The interest rate for the facility that would apply to outstanding principal balances was 8.5% at March 31, 2024.

5

Our credit agreement effective in August 2022 prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of $150 million. The current credit agreement also contains restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at March 31, 2024 and December 31, 2023.

(4) Related Party Transactions

We purchase tires and obtain related services from Bauer Built, Inc., or BBI. Jerry M. Bauer, the chairman of the board and chief executive officer of BBI, is one of our directors. We paid BBI $2,000 in the first three months of 2024 and $89,000 in the first three months of 2023 for tires and related services. In addition, we paid $438,000 in the first three months of 2024 and $436,000 in the first three months of 2023 to tire manufacturers for tires that were provided by BBI. BBI received commissions from the tire manufacturers related to these purchases.

(5) Share Repurchase Program

In August 2019, our Board of Directors approved and we announced an increase from current availability in our existing share repurchase program providing for the repurchase of up to $34.0 million, or approximately 1.8 million shares, of our common stock, which was increased by our Board of Directors to 2.7 million shares in August 2020 to reflect the three-for-twostock split effected in the form of a stock dividend on August 13, 2020. On May 3, 2022, our Board of Directors approved and we announced an additional increase from current availability in our existing share repurchase program providing for the repurchase of up to $50.0 million, or approximately 3.1 million shares of our common stock. The share repurchase program allows purchases on the open market or through private transactions in accordance with Rule 10b-18 of the Exchange Act. The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does not have an expiration date.

We repurchased and retired 1.3 million shares of common stock for $25.0 million in the first quarter of 2022, and 963,000 shares of common stock for $16.8 million in the second quarter of 2022. We did notrepurchase any shares in the first quarter of 2024, in 2023, or in the third or fourth quarters of 2022. As of March 31, 2024, future repurchases of up to $33.2 million, or approximately 2.2 million shares, were available in the share repurchase program.

(6) Dividends

In 2010, we announced that our Board of Directors approved a regular cash dividend program to our stockholders, subject to approval each quarter. Quarterly cash dividends of $0.06 per share of common stock were paid in each of the first quarters of 2024 and 2023 which totaled $4.9 million in each quarter.

(7) Accounting for Share-based Payment Arrangement Compensation

We account for share-based payment arrangements in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 718, Compensation - Stock Compensation. During the first three months of 2024, there were no significant changes to the structure of our stock-based award plans. Pre-tax compensation expense related to stock options and performance unit awards recorded in the first three months of 2024 and 2023 was $353,000 and $354,000, respectively.

(8) Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturity of these instruments.

(9) Commitments and Contingencies

We are committed to new revenue equipment purchases of $185.3 million and construction obligations of $1.6 million for the remainder of 2024. Operating lease obligation expenditures through 2028 total $485,000.

6

We self-insure, in part, for losses relating to workers' compensation, auto liability, general liability, cargo and property damage claims, along with employees' health insurance with varying risk retention levels. We maintain insurance coverage for per-incident and total losses in excess of these risk retention levels in amounts we consider adequate based upon historical experience and our ongoing review, and reserve currently for the estimated cost of the uninsured portion of pending claims.

We are also involved in other legal actions that arise in the ordinary course of business. A number of trucking companies, including us, have been subject to lawsuits alleging violations of various federal and state wage and hour laws. A number of these lawsuits have resulted in the payment of substantial settlements or damages by the defendants.

The outcome of all litigation is difficult to assess or quantify, and the magnitude of the potential loss relating to such lawsuits may remain unknown for substantial periods of time. The cost to defend litigation may also be significant. Not all claims are covered by our insurance, and there can be no assurance that our coverage limits will be adequate to cover all amounts in dispute. To the extent we experience claims that are uninsured, exceed our coverage limits or cause increases in future premiums, the resulting expense could have a materially adverse effect on our business and operating results. 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 effect on our consolidated condensed financial statements, however, any future liability claims or adverse developments in existing claims could impact this analysis.

(10) Revenue and Business Segments

We account for our revenue in accordance with FASB ASC 606, Revenue from Contracts with Customers. We combine our fivecurrent operating segments into fourreporting segments (Truckload, Dedicated, Intermodal and Brokerage) for financial reporting purposes. These four reporting segments are also the appropriate categories for the disaggregation of our revenue under FASB ASC 606.

We have strategically transitioned from a refrigerated long-haul carrier to a multifaceted business offering a network of time and temperature-sensitive and dry truck-based transportation and distribution capabilities across our five distinct business platforms - Truckload, Dedicated, Intermodal, Brokerage and MRTN de Mexico.

Our Truckload segment provides a combination of regional short-haul and medium-to-long-haul full-load transportation services. We transport food and other consumer packaged goods that require a temperature-controlled or insulated environment, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for one year.

Our Dedicated segment provides customized transportation solutions tailored to meet individual customers' requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from threeto fiveyears and are subject to annual rate reviews.

Generally, we are paid by the mile for our Truckload and Dedicated services. We also derive Truckload and Dedicated revenue from fuel surcharges, loading and unloading activities, equipment detention and other accessorial services. The main factors that affect our Truckload and Dedicated revenue are the rate per mile we receive from our customers, the percentage of miles for which we are compensated, the number of miles we generate with our equipment and changes in fuel prices. We monitor our revenue production primarily through average Truckload and Dedicated revenue, net of fuel surcharges, per tractor per week. We also analyze our average Truckload and Dedicated revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our fuel surcharge revenue, our accessorial revenue and our other sources of operating revenue.

Our Intermodal segment transports our customers' freight within the United States utilizing our refrigerated containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affect our Intermodal revenue are the rate per mile and other charges we receive from our customers.

7

Our Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. We retain the billing, collection and customer management responsibilities. The main factors that affect our Brokerage revenue are the rate per mile and other charges that we receive from our customers.

Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.

Our customer agreements are typically for one-yearterms except for our Dedicated agreements which range from three to five years with annual rate reviews. Under FASB ASC 606, the contract date for each individual load within each of our four reporting segments is generally the date that each load is tendered to and accepted by us. For each load transported within each of our four reporting segments, the entire amount of revenue to be recognized is a single performance obligation and our agreements with our customers detail the per-mile charges for line haul and fuel surcharges, along with the rates for loading and unloading, stop offs and drops, equipment detention and other accessorial services, which is the transaction price. There are no discounts that would be a material right or consideration payable to a customer. We are required to recognize revenue and related expenses over time, from load pickup to delivery, for each load within each of our four reporting segments. We base our calculation of the amount of revenue to record in each period for individual loads picking up in one period and delivering in the following period using the number of hours estimated to be incurred within each period applied to each estimated transaction price. Contract assets for this estimated revenue which are classified within prepaid expenses and other within our consolidated condensed balance sheets were $2.9 million and $2.1 million as of March 31, 2024 and December 31, 2023, respectively. We had noimpairment losses on contract assets in the first three months of 2024 or in 2023. We bill our customers for loads after delivery is complete with standard payment terms of 30 days.

We account for revenue of our Intermodal and Brokerage segments and revenue on freight transported by independent contractors within our Truckload and Dedicated segments on a gross basis because we are the principal service provider controlling the promised service before it is transferred to each customer. We are primarily responsible for fulfilling the promise to provide each specified service to each customer. We bear the primary risk of loss in the event of cargo claims by our customers. We also have complete control and discretion in establishing the price for each specified service. Accordingly, all such revenue billed to customers is classified as operating revenue and all corresponding payments to carriers for transportation services we arrange in connection with brokerage and intermodal activities and to independent contractor providers of revenue equipment are classified as purchased transportation expense within our consolidated condensed statements of operations.

The following table sets forth for the periods indicated our operating revenue and operating income by segment. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment.

(11) Use of Estimates

We must make estimates and assumptions to prepare the consolidated condensed financial statements in conformity with U.S. generally accepted accounting principles. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities in the consolidated condensed financial statements and the reported amount of revenue and expenses during the reporting period. These estimates are primarily related to insurance and claims accruals and depreciation. Ultimate results could differ from these estimates.

We also analyze our average Truckload and Dedicated revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our fuel surcharge revenue, our accessorial revenue and our other sources of operating revenue.

Our Intermodal segment transports our customers' freight within the United States utilizing our refrigerated containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affect our Intermodal revenue are the rate per mile and other charges we receive from our customers.

Our Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. We retain the billing, collection and customer management responsibilities. The main factors that affect our Brokerage revenue are the rate per mile and other charges that we receive from our customers.

Operating results of our MRTN de Mexico business which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers is reported within our Truckload and Brokerage segments.

In addition to the factors discussed above, our operating revenue is also affected by, among other things, the United States economy, inventory levels, the level of truck and rail capacity in the transportation market, a contracting driver market, severe weather conditions and specific customer demand.

Our operating revenue decreased $48.4 million, or 16.2%, in the first three months of 2024 from the first three months of 2023. Our operating revenue, net of fuel surcharges, decreased $39.2 million, or 15.4%, compared with the first three months of 2023. Truckload segment revenue, net of fuel surcharges, decreased 7.1% from the first three months of 2023, primarily due to a decrease in our average revenue per tractor, despite an increase in our average fleet size. Dedicated segment revenue, net of fuel surcharges, decreased 17.4% from the first three months of 2023, primarily due to decreases in both our average fleet size and our average revenue per tractor. Intermodal segment revenue, net of fuel surcharges, decreased 43.2% from the first three months of 2023, primarily due to decreases in both our number of loads and our revenue per load. Brokerage segment revenue decreased 15.7% from the first three months of 2023, primarily due to a decrease in our revenue per load. Fuel surcharge revenue decreased to $33.9 million in the first three months of 2024 from $43.1 million in the first three months of 2023.

Our profitability is impacted by the variable costs of transporting freight for our customers, fixed costs, and expenses containing both fixed and variable components. The variable costs include fuel expense, driver-related expenses, such as wages, benefits, training and recruitment, and independent contractor costs, which are recorded under purchased transportation. Expenses that have both fixed and variable components include maintenance and tire expense and our cost of insurance and claims. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, fleet age, efficiency and other factors. Our main fixed costs relate to the acquisition and subsequent depreciation of long-term assets, such as revenue equipment and operating terminals. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of higher prices of new equipment, along with any increases in fleet size. Although certain factors affecting our expenses are beyond our control, we monitor them closely and attempt to anticipate changes in these factors in managing our business. For example, fuel prices have significantly fluctuated over the past several years. We manage our exposure to changes in fuel prices primarily through fuel surcharge programs with our customers, as well as through volume fuel purchasing arrangements with national fuel centers and bulk purchases of fuel at our terminals. To help further reduce fuel expense, we have installed and tightly manage the use of auxiliary power units in our tractors to provide climate control and electrical power for our drivers without idling the tractor engine, and also have improved the fuel usage in the temperature-control units on our trailers. For our Intermodal and Brokerage segments, our profitability is impacted by the percentage of revenue which is payable to the providers of the transportation services we arrange. This expense is included within purchased transportation in our consolidated condensed statements of operations.

Our operating income declined 57.8% to $12.3 million in the first three months of 2024 from $29.0 million in the first three months of 2023. Our operating expenses as a percentage of operating revenue, or "operating ratio," was 95.1% in the first three months of 2024 and 90.3% in the first three months of 2023. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, increased to 94.3% in the first three months of 2024 from 88.6% in the first three months of 2023. Our net income declined 57.1% to $9.6 million, or $0.12 per diluted share, in the first three months of 2024 from $22.5 million, or $0.28 per diluted share, in the first three months of 2023.

Our business requires substantial ongoing capital investments, particularly for new tractors and trailers. At March 31, 2024, we had $73.7 million of cash and cash equivalents, $762.4 million in stockholders' equity and no long-term debt outstanding. In the first three months of 2024, net cash flows provided by operating activities of $45.7 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $18.4 million, to pay cash dividends of $4.9 million and to construct and upgrade regional operating facilities in the amount of $1.6 million, resulting in a $20.5 million increase in cash and cash equivalents. We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $135 million for the remainder of 2024. Quarterly cash dividends of $0.06 per share of common stock were paid in the first three months of 2024 which totaled $4.9 million. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

We continue to invest considerable time and capital resources to actively implement and promote long-term environmentally sustainable solutions that drive reductions in our fuel and electricity consumption and decrease our carbon footprint. These initiatives include (i) reducing idle time for our tractors by installing and tightly managing the use of auxiliary power units, which are powered by solar panels and provide climate control and electrical power for our drivers without idling the tractor engine, (ii) improving the energy efficiency of our newer, more aerodynamic and well-maintained tractor and trailer fleets by optimizing the equipment's specifications, weight and tractor speed, equipping our tractors with automatic transmissions, converting the refrigeration units in our refrigerated trailers to the new, more-efficient CARB refrigeration units along with increasing the insulation in the trailer walls and installing trailer skirts, and using ultra-fuel efficient and wide-based tires, and (iii) upgrading all of our facilities to indoor and outdoor LED lighting along with converting all of our facilities to solar power. Additionally, we are an active participant in the United States Environmental Protection Agency, or EPA, SmartWay Transport Partnership, in which freight shippers, carriers, logistics companies and other voluntary stakeholders partner with the EPA to measure, benchmark and improve logistics operations to reduce their environmental footprint.

This Management's Discussion and Analysis of Financial Condition and Results of Operations includes discussions of operating revenue, net of fuel surcharge revenue; Truckload, Dedicated and Intermodal revenue, net of fuel surcharge revenue; operating expenses as a percentage of operating revenue, each net of fuel surcharge revenue; and net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads). We provide these additional disclosures because management believes these measures provide a more consistent basis for comparing results of operations from period to period. These financial measures in this report have not been determined in accordance with U.S. generally accepted accounting principles (GAAP). Pursuant to Item 10(e) of Regulation S-K, we have included the amounts necessary to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures of operating revenue, operating expenses divided by operating revenue, and fuel and fuel taxes.

Our operating revenue decreased $48.4 million, or 16.2%, to $249.7 million in the 2024 period from $298.0 million in the 2023 period. Our operating revenue, net of fuel surcharges, decreased $39.2 million, or 15.4%, to $215.7 million in the 2024 period from $254.9 million in the 2023 period. This decrease in the 2024 period was due to a $15.1 million decrease in Dedicated revenue, net of fuel surcharges, a $10.1 million decrease in Intermodal revenue, net of fuel surcharges, a $7.3 million decrease in Truckload revenue, net of fuel surcharges, and a $6.7 million decrease in Brokerage revenue. Fuel surcharge revenue decreased to $33.9 million in the 2024 period from $43.1 million in the 2023 period.

In addition to the factors discussed below, our profitability across each segment in the 2024 period was impacted by a freight market which has considerably softened from the conditions during the 2023 period.

Truckload segment revenue decreased $9.1 million, or 7.5%, to $111.6 million in the 2024 period from $120.6 million in the 2023 period. Truckload segment revenue, net of fuel surcharges, decreased $7.3 million, or 7.1%, to $95.0 million in the 2024 period from $102.3 million in the 2023 period, primarily due to a decrease in our average revenue per tractor, despite an increase in our average fleet size. The operating ratio increased to 99.6% in the 2024 period from 91.7% in the 2023 period. Impacting the 2024 period operating ratio was a decrease in our average revenue per tractor along with higher company driver compensation, depreciation, maintenance, net fuel costs and a lower gain on disposition of revenue equipment, as a percentage of revenue.

Dedicated segment revenue decreased $20.0 million, or 18.8%, to $86.5 million in the 2024 period from $106.4 million in the 2023 period. Dedicated segment revenue, net of fuel surcharges, decreased 17.4%, primarily due to decreases in both our average fleet size and our average revenue per tractor. The operating ratio increased to 89.3% in the 2024 period from 87.1% in the 2023 period. Impacting the 2024 period operating ratio was a decrease in our average revenue per tractor along with higher depreciation costs and a lower gain on disposition of revenue equipment, as a percentage of revenue.

Intermodal segment revenue decreased $12.6 million, or 44.1%, to $16.0 million in the 2024 period from $28.6 million in the 2023 period. Intermodal segment revenue, net of fuel surcharges, decreased 43.2% from the 2023 period, primarily due to decreases in both our number of loads and our revenue per load. The operating ratio in the 2024 period increased to 101.2% from 97.2% in the 2023 period. Impacting the 2024 period operating ratio was a decrease in our revenue per load along with higher depreciation and maintenance costs, as a percentage of revenue.

Brokerage segment revenue decreased $6.7 million, or 15.7%, to $35.7 million in the 2024 period from $42.4 million in the 2023 period, primarily due to a decrease in our revenue per load. The operating ratio in the 2024 period of 92.4% was up from 89.4% in the 2023 period. This increase was primarily due to an increase in amounts payable to carriers for transportation services which we arranged, along with higher salaries and wages, as a percentage of our Brokerage revenue.

Salaries, wages and benefits consist of compensation for our employees, including both driver and non-driver employees, employees' health insurance, 401(k) plan contributions and other fringe benefits. These expenses vary depending upon the size of our Truckload, Dedicated and Intermodal tractor fleets, the ratio of company drivers to independent contractors, our efficiency, our experience with employees' health insurance claims, changes in health care premiums and other factors. Salaries, wages and benefits expense decreased $9.8 million, or 9.9%, in the 2024 period from the 2023 period. This decrease resulted primarily from lower company driver compensation expense of $6.6 million, a $1.9 million decrease in employees' health insurance expense due to lower self-insured medical claims and a $763,000 decrease in non-driver compensation expense.

Purchased transportation consists of amounts payable to railroads and carriers for transportation services we arrange in connection with Brokerage and Intermodal operations and to independent contractor providers of revenue equipment. This category will vary depending upon the amount and rates, including fuel surcharges, we pay to third-party railroad and motor carriers, the ratio of company drivers versus independent contractors and the amount of fuel surcharges passed through to independent contractors. Purchased transportation expense decreased $12.3 million in total, or 22.7%, in the 2024 period from the 2023 period. Amounts payable to carriers for transportation services we arranged in our Brokerage segment decreased $5.0 million to $29.8 million in the 2024 period from $34.9 million in the 2023 period, primarily due to decreases in both our cost per load and number of loads. Amounts payable to railroads and drayage carriers for transportation services within our Intermodal segment decreased to $8.1 million in the 2024 period from $15.3 million in the 2023 period, primarily due to decreases in both our number of loads and cost per load. The portion of purchased transportation expense related to independent contractors within our Truckload and Dedicated segments, including fuel surcharges, decreased $68,000 in the 2024 period. We expect our purchased transportation expense to increase as we grow our Intermodal and Brokerage segments.

15

Fuel and fuel taxes decreased by $7.2 million, or 15.5%, in the 2024 period from the 2023 period. Net fuel expense (fuel and fuel taxes net of fuel surcharge revenue and surcharges passed through to independent contractors, outside drayage carriers and railroads) decreased $380,000, or 4.3%, to $8.4 million in the 2024 period from $8.8 million in the 2023 period. Fuel surcharges passed through to independent contractors, outside drayage carriers and railroads decreased to $2.8 million from $5.1 million in the 2023 period. The United States Department of Energy, or DOE, national average cost of fuel decreased to $3.96 per gallon from $4.41 per gallon in the 2023 period. Despite this price decrease, our net fuel expense increased to 4.7% of Truckload, Dedicated and Intermodal segment revenue, net of fuel surcharges, in the 2024 period from 4.1% in the 2023 period. We have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers' fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in the temperature-control units on our trailers. Auxiliary power units, which we have installed in our company-owned tractors, provide climate control and electrical power for our drivers without idling the tractor engine.

Depreciation relates to owned tractors, trailers, containers, auxiliary power units, communication units, terminal facilities and other assets. The $1.0 million, or 3.4%, decrease in depreciation in the 2024 period was primarily due to a decrease in our average tractor fleet size, partially offset by higher prices of new equipment. We expect our annual cost of tractor and trailer ownership will increase in future periods as a result of continued higher prices of new equipment, which will result in greater depreciation over the useful life.

Insurance and claims consist of the costs of insurance premiums and accruals we make for claims within our self-insured retention amounts, primarily for personal injury, property damage, physical damage to our equipment, cargo claims and workers' compensation claims. These expenses will vary primarily based upon the frequency and severity of our accident experience, our self-insured retention levels and the market for insurance. The $3.4 million, or 22.6%, decrease in insurance and claims in the 2024 period was primarily due to decreases in our self-insured auto liability claim costs and in our self-insured cost of physical damage claims related to our revenue equipment, partially offset by higher insurance premiums. Our significant self-insured retention exposes us to the possibility of significant fluctuations in claims expense between periods which could materially impact our financial results depending on the frequency, severity and timing of claims.

Gain on disposition of revenue equipment was $1.2 million in the 2024 period, down from $5.2 million in the 2023 period primarily due to decreases in both the average gain for our tractor and trailer sales and in the number of units sold. Future gains or losses on dispositions of revenue equipment will be impacted by the market for used revenue equipment, which is beyond our control.

Our operating income declined 57.8% to $12.3 million in the 2024 period from $29.0 million in the 2023 period as a result of the foregoing factors. Our operating expenses as a percentage of operating revenue, or "operating ratio," was 95.1% in the 2024 period and 90.3% in the 2023 period. The operating ratio for our Truckload segment was 99.6% in the 2024 period and 91.7% in the 2023 period, for our Dedicated segment was 89.3% in the 2024 period and 87.1% in the 2023 period, for our Intermodal segment was 101.2% in the 2024 period and 97.2% in the 2023 period, and for our Brokerage segment was 92.4% in the 2024 period and 89.4% in the 2023 period. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, was 94.3% in the 2024 period and 88.6% in the 2023 period.

Our effective income tax rate increased to 26.1% in the 2024 period from 24.6% in the 2023 period.

As a result of the factors described above, net income declined 57.1% to $9.6 million, or $0.12 per diluted share, in the 2024 period from $22.5 million, or $0.28 per diluted share, in the 2023 period.

Liquidity and Capital Resources

Our business requires substantial ongoing capital investments, particularly for new tractors and trailers. Our primary sources of liquidity are funds provided by operations and our revolving credit facility. A portion of our tractor fleet is provided by independent contractors who own and operate their own equipment. We have no capital expenditure requirements relating to those drivers who own their tractors or obtain financing through third parties.

The table below reflects our net cash flows provided by operating activities, net cash flows used for investing activities and net cash flows used for financing activities for the periods indicated.

In August 2019, our Board of Directors approved and we announced an increase from current availability in our existing share repurchase program providing for the repurchase of up to $34.0 million, or approximately 1.8 million shares, of our common stock, which was increased by our Board of Directors to 2.7 million shares in August 2020 to reflect the three-for-two stock split effected in the form of a stock dividend on August 13, 2020. On May 3, 2022, our Board of Directors approved and we announced an additional increase from current availability in our existing share repurchase program providing for the repurchase of up to $50.0 million, or approximately 3.1 million shares, of our common stock. The share repurchase program allows purchases on the open market or through private transactions in accordance with Rule 10b-18 of the Exchange Act. The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does not have an expiration date.

We repurchased and retired 1.3 million shares of common stock for $25.0 million in the first quarter of 2022, and 963,000 shares of common stock for $16.8 million in the second quarter of 2022. We did not repurchase any shares in the first quarter of 2024, in 2023, or in the third or fourth quarters of 2022. As of March 31, 2024, future repurchases of up to $33.2 million, or approximately 2.2 million shares, were available in the share repurchase program.

In the first three months of 2024, net cash flows provided by operating activities of $45.7 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $18.4 million, to pay cash dividends of $4.9 million and to construct and upgrade regional operating facilities in the amount of $1.6 million, resulting in a $20.5 million increase in cash and cash equivalents. In the first three months of 2023, net cash flows provided by operating activities of $49.2 million were primarily used to purchase new revenue equipment, net of proceeds from dispositions, in the amount of $26.1 million, to pay cash dividends of $4.9 million and to construct and upgrade regional operating facilities in the amount of $2.1 million, resulting in a $15.7 million increase in cash and cash equivalents.

We estimate that capital expenditures, net of proceeds from dispositions, will be approximately $135 million for the remainder of 2024. This amount includes commitments to purchase $185.3 million of new revenue equipment, prior to considering proceeds from dispositions, and construction obligations of $1.6 million. Additionally, operating lease obligations total $485,000 through 2028. Quarterly cash dividends of $0.06 per share of common stock were paid in each of the first quarters of 2024 and 2023 which totaled $4.9 million in each quarter. We currently expect to continue to pay quarterly cash dividends in the future. The payment of cash dividends in the future, and the amount of any such dividends, will depend upon our financial condition, results of operations, cash requirements and certain corporate law requirements, as well as other factors deemed relevant by our Board of Directors. We believe our sources of liquidity are adequate to meet our current and anticipated needs for at least the next twelve months. Based upon anticipated cash flows, existing cash and cash equivalents balances, current borrowing availability and other sources of financing we expect to be available to us, we do not anticipate any significant liquidity constraints in the foreseeable future.

In August 2022, we entered into a credit agreement that provides for an unsecured committed credit facility with an aggregate principal amount of $30.0 million which matures in August 2027. The credit agreement amends, restates and continues in its entirety our previous credit agreement, as amended. At March 31, 2024, there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $20.7 million and remaining borrowing availability of $9.3 million. At December 31, 2023, there was also no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit of $20.7 million on the facility. This facility bears interest at a variable rate based on the Term SOFR Rate plus applicable margins. The interest rate for the facility that would apply to outstanding principal balances was 8.5% at March 31, 2024.

Our credit agreement effective in August 2022 prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of $150 million. The current credit agreement also contains restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at March 31, 2024 and December 31, 2023.

Other than our obligations for revenue equipment and construction purchases and operating lease expenditures, along with our outstanding standby letters of credit to guarantee settlement of self-insurance claims, which are each mentioned above, we did not have any material off-balance sheet arrangements at March 31, 2024.

Seasonality

Our tractor productivity generally decreases during the winter season because inclement weather impedes operations and some shippers reduce their shipments. At the same time, operating expenses generally increase, with harsh weather creating higher accident frequency, increased claims, lower fuel efficiency and more equipment repairs.

Critical Accounting Estimates

There have been no material changes in the critical accounting estimates disclosed by us under Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates contained in the Annual Report on Form 10-K for the year ended December 31, 2023.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

We are exposed to a variety of market risks, most importantly the effects of the price and availability of diesel fuel. We require substantial amounts of diesel fuel to operate our tractors and power the temperature-control units on our trailers. The price and availability of diesel fuel can vary, and are subject to political, economic and market factors that are beyond our control. Significant increases in diesel fuel costs could materially and adversely affect our results of operations and financial condition. Based upon our fuel consumption in the first three months of 2024, a 5% increase in the average cost of diesel fuel would have increased our fuel expense by $1.9 million.

We have historically been able to pass through a significant portion of long-term increases in diesel fuel prices and related taxes to customers in the form of fuel surcharges. Fuel surcharge programs are widely accepted among our customers, though they can vary somewhat from customer-to-customer. These fuel surcharges, which adjust weekly with the cost of fuel, enable us to recover a substantial portion of the higher cost of fuel as prices increase. These fuel surcharge provisions are not effective in mitigating the fuel price increases related to non-revenue miles or fuel used while the tractor is idling. In addition, we have worked diligently to control fuel usage and costs by improving our volume purchasing arrangements and optimizing our drivers' fuel purchases with national fuel centers, focusing on shorter lengths of haul, installing and tightly managing the use of auxiliary power units in our tractors to minimize engine idling and improving fuel usage in our trailers' refrigeration units.

While we do not currently have any outstanding hedging instruments to mitigate this market risk, we may enter into derivatives or other financial instruments to hedge a portion of our fuel costs in the future.
