NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

​

NOTE A – ORGANIZATIO N AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

​

ArcBest Corporation™ (the “Company”) is a multibillion-dollar integrated logistics company that leverages technology and a full suite of shipping and logistics solutions to meet customers’ supply chain needs and help keep the global supply chain moving. The Company’s operations are conducted through its two reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); and Asset-Light, which includes MoLo Solutions, LLC (“MoLo”), Panther Premium Logistics® (“Panther”), and certain other subsidiaries. References to the Company in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis.

​

The Asset-Based segment represented approximately 63% of the Company’s total revenues before other revenues and intercompany eliminations for the nine months ended September 30, 2023. As of September 2023, approximately 82% of the Asset-Based segment’s employees were covered under the collective bargaining agreement, the ABF National Master Freight Agreement (the “2023 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which was ratified on June 30, 2023 by a majority of ABF Freight’s IBT member employees. A majority of the 2023 ABF NMFA supplements also passed. The remaining supplements were ratified on July 7, 2023. The 2023 ABF NMFA was implemented on July 16, 2023, effective retroactive to July 1, 2023, and will remain in effect through June 30, 2028.

​

The major economic provisions of the 2023 ABF NMFA include wage rate increases in each year of the contract, with the initial increase effective retroactive to July 1, 2023; profit-sharing bonuses upon the Asset-Based segment’s achievement of certain annual operating ratios for any full calendar year under the contract; an additional paid holiday; two additional sick days; and a new non-CDL employee classification. The 2023 ABF NMFA and the related supplemental agreements provide for annual contribution rate increases to multiemployer health and welfare and pension funds to which ABF Freight contributed under the previous agreement. Under the 2023 ABF NMFA, the contractual wages and benefits top hourly rates are estimated to increase approximately 4.2% on a compounded annual basis through the end of the agreement.

​

Financial Statement Presentation

​

On February 28, 2023, the Company sold FleetNet America, Inc. (“FleetNet”), a wholly owned subsidiary and reportable operating segment of the Company, for an aggregate adjusted cash purchase price of $100.9 million, including post-closing adjustments. The sale of FleetNet was a strategic shift for the Company as it exited the fleet roadside assistance and maintenance management business; therefore, the sale was accounted for as discontinued operations. As such, historical results of FleetNet have been excluded from both continuing operations and segment results for all periods presented, and reclassifications have been made to the prior-period financial statements to conform to the current-year presentation. Related assets and liabilities associated with FleetNet are classified as discontinued operations in the consolidated balance sheets for all periods presented. The cash flows related to the discontinued operations have not been segregated and are included in the consolidated statements of cash flows. Unless otherwise indicated, all amounts in this Quarterly Report on Form 10-Q refer to continuing operations, including comparisons to the prior year. For more information on the Company’s discontinued operations, see Note C.

​

Certain reclassifications have been made to the prior-year presentation of other long-term liabilities to conform to the current-year presentation of the contingent consideration liability on a separate line in the consolidated balance sheets. For the three- and nine-month periods ended September 30, 2022, intersegment revenues presented in Note J have been adjusted from those previously reported to correct the breakdown of certain revenues between segments. The adjustments made to the presentation are not material.

​

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the

8

Table of Contents

United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2022 Annual Report on Form 10-K, which have not been adjusted to reflect FleetNet as discontinued operations, and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

​

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates.

​

Accounting Pronouncements Not Yet Adopted

​

Management believes there is no new accounting guidance issued but not yet effective that would have a material impact to the Company’s current financial statements.

​

(1) | Recorded at cost plus accrued interest, which approximates fair value.

(2) | Amounts may be redeemed on a daily basis with the original issuer.

(3) | Recorded at fair value as determined by quoted market prices (see amounts presented in the table of financial assets and liabilities measured at fair value within this Note).

(4) | Recorded at amortized cost plus accrued interest, which approximates fair value. U.S. Treasury securities included in short-term investments are held-to-maturity investments with maturity dates of less than one year.

​

The Company’s long-term financial instruments are presented in the table of financial assets and liabilities measured at fair value within this Note.

​

Concentrations of Credit Risk of Financial Instruments

The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents, and short-term investments. The Company reduces credit risk by maintaining its cash deposits and short-term investments in accounts and certificates of deposit which are primarily FDIC-insured or in direct obligations of the U.S. government. At September 30, 2023 and December 31, 2022, cash deposits and short-term investments which were neither FDIC insured nor direct obligations of the U.S. government totaled $70.2 million and $87.6 million, respectively. The Company also holds money market funds, which are invested in U.S. government securities and repurchase agreements collateralized solely by U.S. government securities.

Fair Value Disclosure of Financial Instruments

Fair value disclosures are made in accordance with the following hierarchy of valuation techniques based on whether the inputs of market data and market assumptions used to measure fair value are observable or unobservable:

​

| ● | Level 1 — Quoted prices for identical assets and liabilities in active markets.

| ● | Level 2 — Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

| ● | Level 3 — Unobservable inputs (Company’s market assumptions) that are significant to the valuation model.

​

Fair value and carrying value disclosures of financial instruments are presented in the following table:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30 | ​ | December 31 | ​
​ |  | 2023 |  | 2022 |

​ | ​ | $ | 262,737 | ​ | $ | 256,249 | ​ | $ | 284,723 | ​ | $ | 276,689 | ​

​

(1) | The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on Secured Overnight Financing Rate (“SOFR”), plus a margin, priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).

(2) | Fair value of the notes payable was determined using a present value income approach based on quoted interest rates from lending institutions with which the Company would enter into similar transactions (Level 2 of the fair value hierarchy).

(3) | ABF Freight’s multiemployer pension plan obligation with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”) was restructured under a transition agreement effective on August 1, 2018, which resulted in a related withdrawal liability. The fair value of the outstanding withdrawal liability is equal to the present value of the future withdrawal liability payments, discounted at an interest rate of 6.1% and 5.3% at September 30, 2023 and December 31, 2022, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). As of September 30, 2023, the outstanding withdrawal liability totaled $19.6 million, of which $0.7 million was recorded in accrued expenses, and the remaining portion was recorded in other long-term liabilities.

(3) | Included in other long-term assets. The fair value of the interest rate swap was determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are generally considered to be in Level 3 of the fair value hierarchy. However, the Company assessed Level 3 inputs as insignificant to the valuation at September 30, 2023 and December 31, 2022 and considers the interest rate swap valuation in Level 2 of the fair value hierarchy.

(4) | As part of the Agreement and Plan of Merger (the “Merger Agreement”) of MoLo, executed in November 2021, certain additional cash consideration is required to be paid by the Company based on the achievement of certain incremental targets of adjusted earnings before interest, taxes, depreciation, and amortization for each of the years ended December 31, 2023, 2024, and 2025. At 100% of the target, the cumulative additional consideration for years 2023 through 2025 would be $215.0 million, with the possible undiscounted cash consideration due ranging from a total of $95.0 million at 80% of target to $455.0 million at 300% of target, as outlined in the Merger Agreement. The estimated fair value of contingent earnout consideration is determined by assessing Level 3 inputs. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and earnings before interest, taxes, depreciation, and amortization to be achieved for the applicable performance periods, volatility factors applied to the simulations, and the discount rate applied, which was 14.5% and 14.0% as of September 30, 2023 and December 31, 2022, respectively. Changes in the significant unobservable inputs might result in a significantly higher or lower fair value at the reporting date. As of September 30, 2023, the contingent earnout consideration was recorded in long-term liabilities based on the September 30, 2023 remeasurement as achievement of the 2023 target is not expected. The decrease in fair value of contingent earnout consideration as of September 30, 2023, compared to December 31, 2022, reflects revised assumptions for

Assets Measured at Fair Value on a Nonrecurring Basis

​

The Company remeasures certain assets on a nonrecurring basis upon the occurrence of certain events. During the nine months ended September 30, 2023, the Company remeasured the fair value of its equity investments in private entities upon an observable price change and remeasured certain long-lived operating lease right-of-use assets and leasehold improvements for which impairment charges were recognized during the period.

(1) | Represents the Company’s equity investment in Phantom Auto, a provider of human-centered remote operation software. The equity investment is accounted for as a nonmarketable equity security without a readily determinable value using the measurement alternative, which allows for the investment to be recorded at cost, less any impairment and adjusted for observable price changes in orderly transactions for an identical or similar equity security of the same issuer. The $3.7 million increase in fair value of the Company’s equity investment was measured as of April 26, 2023, based on an observable price change upon the closing of Phantom Auto’s Series B-2 funding round. The fair value of the investment was estimated using a hybrid method of the Black-Scholes option pricing model and the probability-weighted expected return method. This method produces a per-share value based on a probability-weighted scenario analysis. The scenarios reflect changes to the liquidation preferences based on the potential liquidity event. The Black-Scholes option pricing model used various inputs, including expected volatility, expected term to liquidity, risk-free rate over the expected term, breakpoints values, and liquidation preferences.

NOTE C – DISCONTINUED OPERATIONS

​

On February 28, 2023, the Company sold FleetNet, a wholly owned subsidiary of the Company, for an aggregate adjusted cash purchase price of $100.9 million, and recorded a pre-tax gain on sale of $70.2 million, or $52.3 million, net of tax. FleetNet provided roadside repair solutions and vehicle maintenance management services for commercial and private fleets through a network of third-party service providers. The sale of FleetNet allows the Company to focus on growing its continuing operations, as FleetNet was no longer core to the Company’s growth initiatives. The financial results of FleetNet have been accounted for as discontinued operations for all periods presented.

NOTE E – INCOME TAXES

​

The Company’s total effective tax rate was 25.5% and 23.1% for the three and nine months ended September 30, 2023, respectively, compared to 22.7% and 23.3% for the same periods of 2022, including discontinued operations which are further discussed in Note C. The effective tax rate from continuing operations was 25.5% and 21.6% for the three and nine months ended September 30, 2023, respectively, compared to 22.6% and 23.3% for the same periods of 2022. State tax rates vary among states and average approximately 6.0% to 6.5%, although some state rates are higher, and a small number of states do not impose an income tax.

​

For the three and nine months ended September 30, 2023 and 2022, the difference between the Company’s effective tax rate from continuing operations and the federal statutory rate resulted from state income taxes, nondeductible expenses, changes in the cash surrender value of life insurance, the federal research and development tax credit, changes in tax valuation allowances, the federal alternative fuel tax credit and the tax benefit from the vesting of stock awards.

​

As of September 30, 2023, the Company’s deferred tax liabilities, which will reverse in future years, exceeded the deferred tax assets. The Company evaluated the total deferred tax assets at September 30, 2023, and concluded that, other than for certain deferred tax assets related to foreign and state tax credit carryforwards and state net operating losses, the assets did not exceed the amount for which realization is more likely than not. In making this determination, the Company considered the future reversal of existing taxable temporary differences, future taxable income, and tax planning strategies. Valuation allowances for deferred tax assets totaled $1.8 million and $1.7 million at September 30, 2023 and December 31, 2022, respectively.

​

During the nine months ended September 30, 2023 and 2022, the Company paid federal, state, and foreign income taxes of $78.3 million and $87.5 million, respectively, and received refunds of federal and state income taxes that were paid in prior years of $1.7 million and $1.2 million, respectively.

​

Table of Contents

Income tax reflected in discontinued operations was a tax benefit of less than $0.1 million, or an effective tax benefit rate of 25.5%, and tax expense of $18.3 million, or an effective tax rate of 25.5%, for the three and nine months ended September 30, 2023, respectively, which primarily consisted of federal and state income taxes on the gain on the sale of FleetNet. For the three and nine months ended September 30, 2022, income tax expense reflected in discontinued operations was $0.2 million, or an effective tax rate of 49.1%, and $1.1 million, or an effective tax rate of 27.9%, respectively.

Lease Impairment Charges

​

Long-lived assets, including operating right-of-use assets, are reviewed for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. During the third quarter of 2023, the Company evaluated for impairment certain long-lived operating right-of-use assets that were made available for sublease. The assets evaluated for impairment include the right-of-use assets and leasehold improvements for a service center within the Asset-Based segment from which operations were relocated to a recently purchased facility; certain office spaces within the Asset-Light segment that have been vacated as a cost reduction measure in light of ongoing market changes impacting the Asset-Light business and changing employee work location trends; and certain leased facilities reported within “Other and eliminations” utilized for the service center operations of a freight handling pilot location, as operations transitioned back to the owned Asset-Based service center facility where they had previously been located, following the pause of the hardware pilot program at ABF Freight.

​

After determining the carrying values of these asset groups were not recoverable, impairment was measured and lease impairment charges were recognized for the amount by which the carrying value exceeded the fair value of the asset groups. To estimate the fair value of the asset groups, the Company relied on a discounted cash flow method utilizing market-participant discount rates estimated with Level 3 inputs (see Note B).

​

As a result of these evaluations, the Company recognized $30.2 million of lease impairment charges as a component of operating expenses in the consolidated statements of operations for the three and nine months ended September 30, 2023. The impairment losses recorded include $28.1 million related to the operating right-of-use assets with the remaining amount related to leasehold improvements. The Company determined the right-of-use assets and leasehold improvements are not or will not be abandoned, as there is a plan to sublease the properties, and the right-of-use assets will continue to be classified as held and used.

Financing Arrangements

​

Credit Facility

As of September 30, 2023, the Company has a revolving credit facility (the “Credit Facility”) under its Fourth Amended and Restated Credit Agreement (the “Credit Agreement”), with an initial maximum credit amount of up to $250.0 million, including a swing line facility in an aggregate amount of up to $40.0 million and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million. The Company may request additional revolving commitments or incremental term loans thereunder up to an aggregate amount of $125.0 million, subject to the satisfaction of certain additional conditions as provided in the Credit Agreement. As of September 30, 2023, the Company had available borrowing capacity of $200.0 million under the initial maximum credit amount of the Credit Facility.

​

Principal payments under the Credit Facility are due upon maturity of the facility on October 7, 2027; however, borrowings may be repaid, at the Company’s discretion, in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. In addition, the Credit Facility requires the Company to pay a fee on unused commitments. The Credit Agreement contains conditions, representations and warranties, events of default, and indemnification provisions that are customary for financings of this type, including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, and sales of assets. The Company was in compliance with the covenants under the Credit Agreement at September 30, 2023.

​

Interest Rate Swap

As noted in the table above, the Company has an interest rate swap agreement with a $50.0 million notional amount, which will end on October 1, 2024. The Company will receive floating-rate interest amounts based on one-month SOFR in exchange for fixed-rate interest payments of 0.33% throughout the remaining term of the agreement. The fair value of the interest rate swap of $2.5 million and $3.5 million was recorded in other long-term assets at September 30, 2023 and December 31, 2022, respectively.

​

Table of Contents

The unrealized gain or loss on the interest rate swap instrument in effect at the balance sheet date was reported as a component of accumulated other comprehensive income, net of tax, in stockholders’ equity at September 30, 2023 and December 31, 2022, and the change in the unrealized gain or loss on the interest rate swap for the three and nine months ended September 30, 2023 and 2022 was reported in other comprehensive income (loss), net of tax, in the consolidated statements of comprehensive income. The interest rate swap is subject to certain customary provisions that could allow the counterparty to request immediate settlement of the fair value liability or asset upon violation of any or all of the provisions. The Company was in compliance with all provisions of the interest rate swap agreement at September 30, 2023.

​

Accounts Receivable Securitization Program

The Company’s accounts receivable securitization program, which matures on July 1, 2024, provides available cash proceeds of $50.0 million to be provided under the program and has an accordion feature allowing the Company to request additional borrowings up to $100.0 million, subject to certain conditions.

​

Under this program, certain subsidiaries of the Company continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. This wholly owned consolidated subsidiary is a separate bankruptcy-remote entity, and its assets would be available only to satisfy the claims related to the lenders’ interest in the trade accounts receivables. Borrowings under the accounts receivable securitization program bear interest based upon SOFR, plus a margin, and an annual facility fee. The securitization agreement contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio covenant. The Company was in compliance with the covenants under the accounts receivable securitization program at September 30, 2023.

​

The accounts receivable securitization program includes a provision under which the Company may request, and the letter of credit issuer may issue, standby letters of credit, primarily in support of workers’ compensation and third-party casualty claims liabilities in various states in which the Company is self-insured. The outstanding standby letters of credit reduce the availability of borrowings under the program. As of September 30, 2023, standby letters of credit of $10.0 million have been issued under the program, which reduced the available borrowing capacity to $40.0 million.

​

Letter of Credit Agreements and Surety Bond Programs

As of September 30, 2023, the Company had letters of credit outstanding of $10.6 million (including $10.0 million issued under the accounts receivable securitization program). The Company has programs in place with multiple surety companies for the issuance of surety bonds in support of its self-insurance program. As of September 30, 2023, surety bonds outstanding related to the self-insurance program totaled $58.8 million.

​

Notes Payable

The Company has financed the purchase of certain revenue equipment and other equipment through promissory note arrangements, including $27.5 million and $31.0 million for revenue equipment during the three and nine months ended September 30, 2023, respectively.

​

NOTE J – OPERATING SEGMENT DATA

​

The Company uses the “management approach” to determine its reportable operating segments, as well as to determine the basis of reporting the operating segment information. The management approach focuses on financial information that the Company’s management uses to make operating decisions. Management uses revenues, operating expense categories, operating ratios, operating income (loss), and key operating statistics to evaluate performance and allocate resources to the Company’s operations.

​

On February 28, 2023, the Company sold FleetNet, a wholly owned subsidiary and reportable operating segment of the Company. Following the sale, FleetNet is reported as discontinued operations. As such, historical results of FleetNet have been excluded from both continuing operations and segment results for all periods presented, and reclassifications have been made to the prior-period financial statements to conform to the current-year presentation.

​

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage and shipment levels and demand for services, as described below; therefore, operating results for the interim periods presented may not necessarily be indicative of the results for the fiscal year. Inclement weather conditions can adversely affect freight shipments and operating costs of the Asset-Based and Asset-Light segments. Shipments may decline during winter months

22

Table of Contents

because of post-holiday slowdowns and during summer months due to plant shutdowns affecting automotive and manufacturing customers of the Asset-Light segment; however, weather and other disruptive events can result in higher short-term demand for expedite services depending on the impact to customers' supply chains.

​

Historically, the second and third calendar quarters of each year usually have the highest tonnage and shipment levels, while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies; available capacity in the market; the impact of yield initiatives; and the impact of external events or conditions, may influence quarterly business levels. The Company’s yield initiatives, along with increased technology-driven intelligence and visibility with respect to demand, have allowed for shipment optimization in non-peak times, reducing the Company’s susceptibility to seasonal fluctuations in recent years, including the three and nine months ended September 30, 2023 and 2022.

​

The Company’s reportable operating segments are as follows:

​

| ● | The Asset-Based segment includes the results of operations of ABF Freight System, Inc. and certain other subsidiaries. The segment operations include national, inter-regional, and regional transportation of general commodities through standard, expedited, and guaranteed LTL services. The Asset-Based segment provides services to the Asset-Light segment, including freight transportation related to managed transportation solutions and other services.

​

| ● | The Asset-Light segment includes the results of operations of the Company’s service offerings in ground truckload, expedite, dedicated, intermodal, household goods moving, managed transportation, warehousing and distribution, and international freight transportation for air, ocean, and ground. The Asset-Light segment provides services to the Asset-Based segment.

​

The Company’s other business activities and operations that are not reportable segments include ArcBest Corporation (the parent holding company) and certain subsidiaries. Certain costs incurred by the parent holding company and the Company’s shared services subsidiary are allocated to the reportable segments. The Company eliminates intercompany transactions in consolidation. However, the information used by the Company’s management with respect to its reportable operating segments is before intersegment eliminations of revenues and expenses.

​

Shared services represent costs incurred to support all segments, including sales, pricing, customer service, marketing, capacity sourcing functions, human resources, financial services, information technology, and other company-wide services. Certain overhead costs are not attributable to any segment and remain unallocated in “Other and eliminations.” Included in unallocated costs are expenses related to investor relations, legal, the Company’s Board of Directors, and certain technology investments. Shared services costs attributable to the reportable operating segments are predominantly allocated based upon estimated and planned resource utilization-related metrics, such as estimated shipment levels or number of personnel supported. The bases for such charges are modified and adjusted by management when necessary or appropriate to fairly and equitably reflect the actual incidence of cost incurred by the reportable operating segments. Management believes the methods used to allocate expenses are reasonable.

​

Further classifications of operations or revenues by geographic location are impracticable and, therefore, are not provided. The Company’s foreign operations are not significant.

NOTE K – LEGAL PROCEEDINGS, ENVIRONMENTAL MATTERS, AND OTHER EVENTS

​

The Company is involved in various legal actions arising in the ordinary course of business. The Company maintains liability insurance against certain risks arising out of the normal course of its business, subject to certain self-insured retention limits. The Company routinely establishes and reviews the adequacy of reserves for estimated legal, environmental, and self-insurance exposures. While management believes that amounts accrued in the consolidated financial statements are adequate, estimates of these liabilities may change as circumstances develop. Considering amounts recorded, routine legal matters are not expected to have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.

​

Legal Proceedings

​

In January 2023, the Company and MoLo were named as defendants in lawsuits related to an auto accident which involved a MoLo contract carrier. The accident occurred prior to the Company’s acquisition of MoLo on November 1, 2021. The Company intends to vigorously defend against these lawsuits. The Company believes that a loss related to this matter is reasonably possible. The Company cannot estimate the amount or a range of reasonably possible losses for this matter, if any, at this time; however, it is reasonably possible that such amounts could be material to the Company’s financial condition, results of operations, or cash flows. The Company will pursue recovery for its losses, if any, against all available sources, including, but not limited to, insurance and any potentially responsible third parties.

​

Environmental Matters

​

The Company’s subsidiaries store fuel for use in tractors and trucks in underground tanks at certain facilities. Maintenance of such tanks is regulated at the federal and, in most cases, state levels. The Company believes it is in substantial compliance with all such regulations. The Company’s underground storage tanks are required to have leak detection systems. The Company is not aware of any leaks from such tanks that could reasonably be expected to have a material adverse effect on the Company.

​

The Company has received notices from the Environmental Protection Agency (the “EPA”) and others that it has been identified as a potentially responsible party under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, or other federal or state environmental statutes, at several hazardous waste sites. After investigating the Company’s involvement in waste disposal or waste generation at such sites, the Company has either agreed to de minimis settlements or determined that its obligations, other than those specifically accrued with respect to such sites, would involve immaterial monetary liability, although there can be no assurances in this regard. The Company

maintains a reserve within accrued expenses, for estimated environmental cleanup costs of properties currently or previously operated by the Company. Amounts accrued reflect management’s best estimate of the future undiscounted exposure related to identified properties based on current environmental regulations, management’s experience with similar environmental matters, and testing performed at certain sites.

​

On March 20, 2023, ABF Freight entered into a consent decree with the EPA (the “Consent Decree”) to resolve alleged compliance issues under the federal Clean Water Act (the “CWA”) and, as a result, paid civil penalties of $0.5 million, including interest, during the third quarter of 2023. The estimated settlement expense for this matter was reserved within accrued expenses as of December 31, 2022. By the date of the Consent Decree, the Asset-Based service center facilities were in general compliance with the stormwater laws and have ensured compliance with applicable stormwater permits under the CWA. ABF Freight has internally developed an environmental stormwater management strategy, including the delineation of roles and responsibilities for stormwater maintenance and compliance; developing procedures for tracking the permit process, including comprehensive employee training; implementing standard operating procedures; ensuring contractor awareness of stormwater laws; and tracking facility-specific corrective actions throughout the term of the Consent Decree.

​

Other Events

​

During second quarter 2023, the Company received a Notice of Assessment from a state regarding an ongoing sales and use tax audit for the trailing time period of December 1, 2018 to March 31, 2021. This notice is in addition to the February 2021 Notice of Assessment from that state pertaining to uncollected sales and use tax, including interest and penalties, for the period September 1, 2016 to November 30, 2018. The Company does not agree with the basis of these assessments and filed an appeal for the 2023 assessment in October 2023 on the same legal basis as the appeal filed in May 2021 for the earlier assessment. The Company has previously accrued an amount related to these assessments consistent with applicable accounting guidance, but if the state prevails in its position, the Company may owe additional tax. Management does not believe the resolution of this matter will have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.

​

The Company is working to settle a dispute relating to the classification of exempt versus nonexempt status for certain MoLo employees. To date, no lawsuit has been filed against MoLo or the Company. However, the Company believes that a loss related to this matter is reasonably possible. The Company cannot estimate the amount or a range of reasonably possible losses for this matter, if any, at this time; however, it is reasonably possible that such amounts could be material to the Company’s financial condition, results of operations, or cash flows.

ITEM 2. MANAGEMENT’S DISCUSSIO N AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

​

General

​

ArcBest Corporation™ (together with its subsidiaries, the “Company,” “ArcBest®,” “we,” “us,” and “our”) is a multibillion-dollar integrated logistics company that leverages technology and a full suite of shipping and logistics solutions to meet our customers’ supply chain needs and help keep the global supply chain moving. Our operations are conducted through two reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); and Asset-Light, which includes MoLo Solutions, LLC (“MoLo”), Panther Premium Logistics®, and certain other subsidiaries. References to the Company, including “we,” “us,” and “our,” in this Quarterly Report on Form 10-Q, are primarily to the Company and its subsidiaries on a consolidated basis.

​

On February 28, 2023, the Company sold FleetNet America, Inc. (“FleetNet”), a wholly owned subsidiary of the Company, for an aggregate adjusted cash purchase price of $100.9 million, including post-closing adjustments. Following the sale, FleetNet was reported as discontinued operations. As such, historical results of FleetNet have been excluded from both continuing operations and segment results for all periods presented, and reclassifications have been made to the prior-period financial statements to conform to the current-year presentation. Unless otherwise indicated, all amounts in this Quarterly Report on Form 10-Q refer to continuing operations, including comparisons to the prior year. For more information on our discontinued operations, see Note C to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

​

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is provided to assist readers in understanding our financial performance during the periods presented and significant trends which may impact our future performance, including the principal factors affecting our results of operations, liquidity and capital resources, and critical accounting policies. This discussion should be read in conjunction with the accompanying quarterly unaudited consolidated financial statements and the related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q and with our Annual Report on Form 10-K for the year ended December 31, 2022. Our 2022 Annual Report on Form 10-K includes additional information about significant accounting policies, practices, and the transactions that underlie our financial results, as well as a detailed discussion of the most significant risks and uncertainties to which our financial and operating results are subject.

The nine-month period ended September 30, 2023 includes the net gain on sale of FleetNet of $52.3 million (after-tax) or $2.11 diluted earnings per share. Discontinued operations are further described within Note C to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

Our consolidated revenues, which totaled $1,128.4 million and $3,337.9 million for the three and nine months ended September 30, 2023, respectively, decreased 11.6% and 13.6%, respectively, compared to the same prior-year periods. The revenue declines are primarily attributable to lower market rates for shipping and logistics services in a softer market environment with more available capacity, compared to the prior-year periods. The year-over-year decreases in consolidated revenues for the three and nine months ended September 30, 2023 reflect decreases in our Asset-Based revenues of 6.4% and 6.0%, respectively, and decreases in Asset-Light revenues of 18.6% and 23.7%, respectively. The elimination of revenues reported in the “Other and eliminations” line of consolidated revenues increased 3.6% for the three months ended September 30, 2023 and decreased 4.0% for the nine months ended September 30, 2023, compared to the same periods of 2022, reflecting year-over-year changes in intersegment business levels among our operating segments.

​

Our Asset-Based revenue decline reflects a 6.3% per-day decrease in tonnage, partially offset by a 1.9% increase in billed revenue per hundredweight, including fuel surcharges, for the three months ended September 30, 2023, compared to the same period of 2022, and a 4.7% decrease in billed revenue per hundredweight, including fuel surcharges, and a 0.9% per-day decrease in tonnage for the nine months ended September 30, 2023, compared to the same prior-year period. The change in total billed revenue per hundredweight reflects a decrease in fuel surcharge revenue associated with lower fuel prices and changes in business mix. During the first half of 2023, the company increased utilization of dynamically priced,

transactional LTL shipments as the volume of LTL-rated published shipments declined. Following the shutdown of one of our larger LTL competitors in late July 2023 (as further discussed in the Asset-Based Overview within the Asset-Based Operations section) and the resulting decline in LTL industry carrier capacity, our Asset-Based segment experienced an increase in demand for its core, published LTL business and was able to secure these shipments at profitable rates. This increase in published LTL-rated shipments and resulting decrease in transactional business positively impacted the Asset-Based business mix for the third quarter of 2023. For the three and nine months ended September 30, 2023, Asset-Based daily shipments increased 1.5% and 4.5%, respectively, while weight per shipment decreased 7.7% and 5.1%, respectively, compared to the same prior-year periods.

​

The decrease in revenues of our Asset-Light segment for the three and nine months ended September 30, 2023, compared to the same prior-year periods, reflects a 22.8% and 28.0% decrease in revenue per shipment, respectively. The revenue decrease was impacted by changes in business mix associated with softer market conditions, partially offset by a 3.7% and 2.7% increase in shipments per day, respectively, resulting from growth in the truckload business. The Asset-Light operating segment generated approximately 36% and 37% of our total revenues before other revenues and intercompany eliminations for the three and nine months ended September 30, 2023, respectively, compared to approximately 39% and 42%, respectively, for the same periods of 2022.

​

Consolidated operating income totaled $45.1 million and $108.4 million for the three and nine months ended September 30, 2023, respectively, compared to $115.3 million and $344.3 million, respectively, for the same periods of 2022. Operating expenses for the three- and nine-month periods ended September 30, 2023, compared to the same prior-year periods, were impacted by lower purchased transportation costs in the Asset-Light and Asset-Based segments and lower employee costs in the Asset-Light segment due to the alignment of costs to business levels, offset partially by higher employee costs in the Asset-Based segment due to union wage rate increases and higher headcount. Segment operating expenses are further described in the Asset-Based Segment Results and Asset-Light Segment Results sections of Results of Operations. In addition to the results of our operating segments, the year-over-year comparison of consolidated operating income was impacted by items described in the following paragraphs.

​

Innovative technology costs impacted our consolidated and Asset-Based segment results for the three and nine months ended September 30, 2023 and 2022. These costs include the freight handling pilot test program at ABF Freight, as further discussed in the Asset-Based Segment Results section. In March 2023, we launched our customer offering of Vaux™ – the innovative suite of hardware and software, which modernizes and transforms how freight is loaded, unloaded, and transferred in warehouse and dock operations. Certain costs related to our growing number of Vaux pilot programs in customer test locations and other initiatives to optimize our performance through technological innovation are reported in the “Other and eliminations” line of consolidated operating income. These combined innovative technology costs impacted consolidated results by a total of $14.1 million (pre-tax), or $10.6 million (after-tax) and $0.43 per diluted share, for third quarter 2023, compared to $10.1 million (pre-tax), or $7.6 million (after-tax) and $0.30 per diluted share, for third quarter 2022. For the nine months ended September 30, 2023, these costs impacted consolidated results by a total of $41.4 million (pre-tax), or $31.3 million (after-tax) and $1.26 per diluted share, compared to $30.1 million (pre-tax), or $22.7 million (after-tax) and $0.89 per diluted share, for the same period of 2022.

​

The liability for contingent earnout consideration recorded for the MoLo acquisition is remeasured at each quarterly reporting date, and any change in fair value as a result of the recurring assessments is recognized in operating income. The quarterly remeasurement of the contingent earnout consideration increased consolidated results by $17.8 million (pre-tax), or $13.4 million (after-tax) and $0.55 per diluted share in the third quarter of 2023, with no comparable adjustment recognized in the third quarter of 2022. For the nine months ended September 30, 2023, the quarterly remeasurements increased consolidated results by $12.8 million (pre-tax), or $9.6 million (after-tax) and $0.39 per diluted share, while quarterly remeasurements reduced consolidated operating results by $0.8 million (pre-tax), or $0.6 million (after-tax) and $0.02 per diluted share, for the same period of 2022. Remeasurement of the contingent earnout consideration is further described within Note B to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

The Company recognized lease impairment charges during the third quarter of 2023 related to a freight handling pilot facility, a service center, and certain office spaces that were made available for sublease, as further described within Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. For the three

and nine months ended September 30, 2023, lease impairment charges reduced operating results by $30.2 million (pre-tax), or $22.6 million (after-tax), and $0.92 per diluted share and $0.91 per diluted share for the three and nine months ended September 30, 2023, respectively. Remeasurement of the right-of-use assets and leasehold improvements is further described within Note B to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

In addition to the above items, the year-over-year changes in consolidated net income and earnings per share were impacted by changes in the cash surrender value of variable life insurance policies, changes in the fair value of our equity investment in Phantom Auto, tax benefits from the vesting of share-based compensation awards, tax credits, and other changes in the effective tax rate as described within the Income Taxes section of MD&A. A portion of our variable life insurance policies have investments, through separate accounts, in equity and fixed income securities and, therefore, are subject to market volatility. Changes in the cash surrender value of life insurance policies, which are reported below the operating income line in the consolidated statements of operations, increased consolidated net income by $0.2 million, or $0.01 per diluted share, and $2.8 million, or $0.11 per diluted share, for the three and nine months ended September 30, 2023, respectively, compared to a decrease in net income of $0.2 million, or $0.01 per diluted share, and $3.7 million, or $0.14 per diluted share, for the same respective prior-year periods. We recorded an adjustment to the fair value of our equity investment in Phantom Auto, a provider of human-centered remote operation software, based on an observable price change during second quarter 2023, which increased consolidated net income by $2.8 million, or $0.11 per diluted share, for the nine-month period ended September 30, 2023, with no comparable prior-year impact. The change in fair value of our equity investment is further described within Note B to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. The vesting of restricted stock units resulted in a tax benefit of $0.2 million, or $0.01 per diluted share, and $5.1 million, or $0.21 per diluted share, for the three and nine months ended September 30, 2023, respectively, compared to $2.4 million, or $0.09 per diluted share, and $8.3 million, or $0.32 per diluted share, for the same periods of 2022. Consolidated net income and earnings per share were also positively impacted by $2.1 million, or $0.08 per diluted share, for the three and nine months ended September 30, 2022, for amounts recognized during the third quarter of 2022 related to the retroactive reinstatement of the alternative fuel tax credit which was extended in August 2022 with H.R. 5376, the Inflation Reduction Act of 2022 (“the Inflation Reduction Act”).

Consolidated Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”)

We report our financial results in accordance with U.S. generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures and ratios, such as Adjusted EBITDA, utilized for internal analysis provide analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Accordingly, using these measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management’s opinion, do not reflect our core operating performance. Management uses Adjusted EBITDA as a key measure of performance and for business planning. The measure is particularly meaningful for analysis of our operating performance, because it excludes amortization of acquired intangibles and software of the Asset-Light segment and changes in the fair value of contingent earnout consideration and equity investment, and lease impairment charges, which are significant expenses resulting from strategic decisions rather than core daily operations. Additionally, Adjusted EBITDA is a primary component of the financial covenants contained in our Fourth Amended and Restated Credit Agreement (see Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q). Other companies may calculate Adjusted EBITDA differently; therefore, our calculation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. Adjusted EBITDA should not be construed as a better measurement than operating income, operating cash flow, net income, or earnings per share, as determined under GAAP. The following table presents a reconciliation of Adjusted EBITDA to our net income from continuing operations, which is the most directly comparable GAAP measure for the periods presented.

Asset-Based Operations

​

Asset-Based Segment Overview

​

The Asset-Based segment consists of ABF Freight System, Inc., a wholly owned subsidiary of ArcBest Corporation, and certain other subsidiaries. Our Asset-Based segment operates one of North America’s largest less-than-truckload (“LTL”) networks providing freight transportation services. Our customers trust the LTL solutions that ABF Freight has provided for 100 years and rely on us to solve their transportation challenges, through market disruptions and rapidly changing economic conditions. We are strategically investing in our Asset-Based operations to utilize technology to drive efficiency and productivity and provide better experiences for our customers.

Table of Contents

​

Our Asset-Based operations are affected by general economic conditions, as well as a number of other competitive factors that are more fully described in Item 1 (Business) and in Item 1A (Risk Factors) of Part I of our 2022 Annual Report on Form 10-K. See Note J to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for a description of the Asset-Based segment and additional segment information, including revenues, operating expenses, and operating income for the three and nine months ended September 30, 2023 and 2022.

​

The key indicators necessary to understand the operating results of our Asset-Based segment, which are more fully described in the Asset-Based Segment Overview within the Asset-Based Operations section of Results of Operations in Item 7 (MD&A) of Part II of our 2022 Annual Report on Form 10-K, are outlined below. These key indicators are used by management to evaluate segment operating performance and measure the effectiveness of strategic initiatives in the results of our Asset-Based segment. We quantify certain key indicators using key operating statistics which are important measures in analyzing segment operating results from period to period. These statistics are defined within the key indicators below and referred to throughout the discussion of the results of our Asset-Based segment:

​

| ● | Overall customer demand for Asset-Based transportation services, including the impact of economic factors.

​

| ● | Volume of transportation services provided and processed through our network which influences operating leverage as the level of tonnage and number of shipments vary, primarily measured by:

​

Pounds or Tonnage – total weight of shipments processed during the period in U.S. pounds or U.S. tons.

​

Tonnage per day (average daily shipment weight) – tonnage divided by the number of workdays in the period.

​

Shipments per day – total number of shipments moving through the Asset-Based freight network during the period divided by the number of workdays in the period.

​

Pounds per shipment (weight per shipment) – total pounds divided by the number of shipments during the period.

​

Average length of haul (miles) – total miles between origin and destination service centers for all shipments (including shipments moved with purchased transportation) during the period, with miles based on the size of shipments.

​

| ● | Prices obtained for services, including fuel surcharges, primarily measured by:

​

Billed revenue per hundredweight, including fuel surcharges (yield) – revenue per 100 pounds of shipment weight, including fuel surcharges, systematically calculated as shipments are processed in the Asset-Based freight network. Revenue for undelivered freight is deferred for financial statement purposes in accordance with our revenue recognition policy. Billed revenue used for calculating revenue per hundredweight measurements is not adjusted for the portion of revenue deferred for financial statement purposes.

​

| ● | Ability to manage cost structure, primarily in the area of salaries, wages, and benefits (“labor”), with the total cost structure primarily measured by:

​

Operating ratio – the percent of operating expenses to revenue levels.

​

We also quantify certain key operating statistics which are used by management to evaluate productivity of operations within the Asset-Based freight network and to measure the effectiveness of strategic initiatives to manage the segment’s cost structure from period to period. These measures are defined below and further discussed in the Asset-Based Operating Expenses section within Asset-Based Segment Results:

​

| ● | Shipments per DSY hour – total shipments (including shipments handled by purchased transportation agents) divided by dock, street, and yard (“DSY”) hours. This metric is used to measure labor efficiency in the segment’s local operations. The shipments per DSY hour metric will generally increase when more purchased

33

|  | transportation is used; however, the labor efficiency may be offset by increased purchase transportation expense.

​

| ● | Pounds per mile – total pounds divided by total miles driven during the period (including pounds and miles moved with purchased transportation). This metric is used to measure labor efficiency of linehaul operations, although it is influenced by other factors including freight density, loading efficiency, average length of haul, and the degree to which purchased transportation (including rail service) is used.

​

Other companies within our industry may present different key performance indicators or operating statistics, or they may calculate their measures differently; therefore, our key performance indicators or operating statistics may not be comparable to similarly titled measures of other companies. Key performance indicators or operating statistics should be viewed in addition to, and not as an alternative for, our reported results. Our key performance indicators or operating statistics should not be construed as better measurements of our results than operating income, operating cash flow, net income, or earnings per share, as determined under GAAP.

​

As of September 2023, approximately 82% of our Asset-Based segment’s employees were covered under the ABF National Master Freight Agreement (the “2023 ABF NMFA”), the collective bargaining agreement with the IBT, which was ratified on June 30, 2023 by a majority of ABF’s IBT member employees. A majority of the supplements to the 2023 ABF NMFA also passed. Following ratification of the remaining supplements on July 7, 2023, the 2023 ABF NMFA was implemented on July 16, 2023, effective retroactive to July 1, 2023. The 2023 ABF NMFA will remain in effect through June 30, 2028.

​

The terms of the 2023 ABF NMFA continue to provide some of the best wages and benefits in the industry to our contractual employees. The 2023 ABF NMFA provides for wage rate increases in each year of the contract, with the initial increase effective retroactive to July 1, 2023; profit-sharing bonuses upon the Asset-Based segment’s achievement of certain annual operating ratios for any full calendar year under the contract; an additional paid holiday; two additional sick days; and a new non-CDL employee classification. Under the new agreement, ABF Freight continues to pay some of the highest benefit contribution rates in the industry, which includes annual contribution rate increases to multiemployer health and welfare and pension plans to which ABF Freight contributed under the previous 2018 ABF NMFA. Under the 2023 ABF NMFA, the combined contractual wage and benefits top hourly rate is estimated to increase approximately 4.2% on a compounded annual basis through the end of the agreement, with potential profit-sharing bonuses representing additional costs under the 2023 ABF NMFA.

​

On July 30, 2023, one of our larger LTL competitors ceased operations. While the long-term impact of that competitor’s bankruptcy is still uncertain, in the short term, we have seen an increase in demand for core, published LTL business, which was secured at profitable rates. Although we continually evaluate our business mix to ensure revenue optimization, the resulting increase in revenues could be offset partially or entirely by the related increase in expenses to service shipment volumes. There can be no assurance that the prices we secure on these shipments will allow us to maintain the higher shipment volume, or that the higher published LTL-rated shipment volumes experienced during the third quarter of 2023 resulting from this reduction in LTL industry carrier capacity will be maintained as customer re-pricing occurs.

Asset-Based Revenues

Asset-Based segment revenues for the three and nine months ended September 30, 2023, totaled $741.2 million and $2,161.0 million, respectively, compared to $791.5 million and $2,299.5 million for the same periods of 2022. The decrease in revenues, compared to the prior-year periods, primarily reflects a softer market environment and our response to market conditions, which included changes in the Asset-Based business mix. Following the previously discussed shutdown of one of our larger LTL competitors at the end of July 2023, Asset-Based experienced an increase in published LTL-rated shipments at profitable rates as freight was redistributed in the market, resulting in an increase in shipments per day of 1.5% for the three months ended September 30, 2023, compared to the same period of 2022. The increase in published LTL-rated shipments in the third quarter and higher levels of dynamically priced transactional shipments during

35

Table of Contents

the first half of 2023, resulted in an increase in shipments per day of 4.5% for the nine months ended September 30, 2023, compared to the same period of 2022, despite the softer market.

​

While shipment volumes have increased, billed revenue (as described in the Asset-Based Segment Overview) decreased 4.6% and 5.6% on a per-day basis for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022, primarily reflecting a 6.3% decrease in tonnage per day, partially offset by a 1.9% increase in billed revenue per hundredweight, including fuel surcharges for third quarter 2023, and a 4.7% decrease in total billed revenue per hundredweight, including fuel surcharges, and 0.9% decrease in tonnage per day for the nine-month period ended September 30, 2023. The decrease in revenues, compared to the prior-year periods, also reflects the decrease in fuel surcharge revenue associated with lower fuel prices. There was one and a half fewer workdays in the third quarter of 2023, versus the third quarter of 2022, and one less workday in the nine-month period ended September 30, 2023, compared to the same period of 2022.

​

The 6.3% and 0.9% decrease in tonnage per day for the three and nine months ended September 30, 2023, respectively, compared to the same prior-year periods, despite an increase in shipment levels, reflects lower average weight per shipment on both LTL-rated and truckload-rated shipments, primarily related to changes in Asset-Based business mix and macro-economic trends of smaller shipment sizes for our core customers. We began to experience a deceleration in demand trends during third quarter 2022. In this softer market environment, our dynamic pricing option for LTL-rated shipments allowed us to strategically utilize network capacity during the first half of 2023. The previously discussed market disruption related to the shutdown of a large LTL carrier at the end of July 2023 resulted in an increase in available LTL shipments in the market.

​

The 1.9% increase in total billed revenue per hundredweight, including fuel surcharges, for third quarter 2023, compared to third quarter 2022, was driven by a higher proportion of core, published LTL-rated tonnage due to the previously discussed market disruption and higher pricing on fewer dynamic LTL-rated shipments at a lower weight per shipment. The 4.7% decrease in total billed revenue per hundredweight, including fuel surcharges, for the nine months ended September 30, 2023, compared to the same periods of 2022, was negatively impacted by the softened pricing environment and the effect of lower-priced dynamic LTL-rated shipments being a higher proportion of total business than core, published LTL-rated business during the first half of 2023. The percentage change in billed revenue per hundredweight, including fuel surcharges, on LTL-rated freight was a low-single digit increase for the three months ended September 30, 2023, and a mid-single digit decrease for the nine months ended September 30, 2023, compared to the same periods of 2022. Total billed revenue per hundredweight on truckload-rated freight decreased year-over-year for the three and nine months ended September 30, 2023. Lower fuel surcharge revenue associated with decreased fuel prices, compared to the prior-year periods, negatively impacted the billed revenue per hundredweight measure during the three and nine months ended September 30, 2023. The pricing environment for LTL shipments improved following the tightening in market capacity at the end of July 2023, as previously discussed, and continues to be rational. Pricing on core, published LTL-rated business, excluding fuel surcharges, increased by a percentage in the low-single digits for the three months ended September 30, 2023 and in the mid-single digits for the nine months ended September 30, 2023, compared to the same periods of 2022. Prices on accounts subject to deferred pricing agreements and annually negotiated contracts which were renewed during the three and nine months ended September 30, 2023, increased approximately 4.0% and 3.7%, respectively, compared to the same periods of 2022. The quarterly percentage improvements in contractual pricing for the first nine months of 2023 were lower than the year-over-year increases secured in 2022, which were historically high average price increases. The Asset-Based segment implemented general rate increases on its LTL base rate tariffs of 5.9% effective on both November 7, 2022 and October 2, 2023, although the rate changes vary by lane and shipment characteristics.

​

Total shipments increased 1.5% on a per-day basis for the three months ended September 30, 2023, compared to the same period of 2022, primarily due to the increase in core, published LTL-rated shipments, offset partially by a decline in dynamically priced LTL-rated and truckload-rated shipments per day as core LTL shipments were prioritized. Total shipments increased 4.5% on a per-day basis for the nine months ended September 30, 2023, compared to the same period of 2022, primarily due to growth in average daily dynamically priced LTL-rated and truckload-rated shipments during the first half of 2023, offset partially by lower published LTL-rated shipments reflecting reduced order quantities and smaller shipment sizes from existing customers prior to August 2023. The increase in published LTL-rated shipments in third quarter 2023 and the increase in dynamically priced LTL-rated business to maintain more consistent business levels relative

to available capacity in the Asset-Based network during the first half of 2023 contributed to an increased proportion of LTL-rated shipments, which drove the decline in the total weight per shipment metric for the three- and nine-month periods ended September 30, 2023, compared to the same prior-year period.

​

The Asset-Based segment’s average nominal fuel surcharge rate decreased by approximately 10 percentage points and 7 percentage points in the three- and nine-month period ended September 30, 2023, respectively, compared to the same period of 2022. During periods of changing diesel fuel prices, the fuel surcharge and associated direct diesel fuel costs also vary by different degrees. Depending upon the rates of these changes and the impact on costs in other fuel- and energy-related areas, operating margins could be impacted. Whether fuel prices fluctuate or remain constant, operating results may be adversely affected if competitive pressures limit our ability to recover fuel surcharges. In periods of declining fuel prices, fuel surcharge percentages also decrease, which negatively impacts the total billed revenue per hundredweight measure and, consequently, revenues. The revenue decline may be disproportionate to the change in our fuel costs. The segment’s operating results will continue to be impacted by further changes in fuel prices and related fuel surcharges.

​

Asset-Based Operating Income

The Asset-Based segment generated operating income of $74.8 million and $165.6 million for the three and nine months ended September 30, 2023, compared to $109.3 million and $306.0 million for the same periods of 2022. The Asset-Based segment’s operating ratio increased by 3.7 percentage points and 5.6 percentage points for the three and nine months ended September 30, 2023, compared to the same prior-year periods, primarily reflecting decreased revenues.

​

Innovative technology costs related to the freight handling pilot at ABF Freight impacted operating results of the Asset-Based segment by $7.3 million and $21.7 million for the three and nine months ended September 30, 2023, compared to $6.1 million and $21.0 million for the same periods of 2022. The freight handling pilot at ABF Freight includes both hardware and software elements. During the third quarter of 2023, the Company announced that the hardware portion of the pilot would be paused at ABF Freight distribution centers in Kansas City, Missouri and Salt Lake City, Utah, as we refocus the implementation team’s efforts toward training managers and employees on operational best practices. The software portion of the pilot program, which provides greater visibility into Asset-Based operations, will be utilized in the Asset-Based operations network to drive efficiency, productivity, and service improvements. As a result of pausing the hardware portion of the pilot, the Asset-Based segment should not incur further associated innovative technology costs in fourth quarter 2023, while these costs totaled $6.2 million in fourth quarter 2022.

​

Asset-Based Operating Expenses

Labor costs, which are reported in operating expenses as salaries, wages, and benefits, amounted to approximately 48% of Asset-Based segment revenues for the three- and nine-month periods ended September 30, 2023, compared to approximately 42% for the same periods of 2022. The increase in salaries, wages, and benefits as a percentage of revenue for the three and nine months ended September 30, 2023, compared to the same prior-year periods, was partially offset by lower utilization of purchased transportation as discussed later in this section. Salaries, wages, and benefits increased $25.2 million and $63.8 million for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022, primarily due to a 13% increase in union wages related to the wage and mileage rate increases effective July 1, 2023 under the 2023 ABF NMFA and higher headcount as additional drivers and service center personnel have been hired over the past year to support higher shipment levels. Higher utilization of dynamically priced LTL shipments during the first half of 2023, as previously discussed in the Asset-Based Revenues section, enabled the segment to add incremental revenue and maintain headcount in the nine-month period ended September 30, 2023, despite the weaker economic environment, while also preserving system capacity for a market rebound. The increases in labor costs also reflect year-over-year increases in contractual benefit contribution rates under the labor agreements with the IBT. The average health, welfare, and pension benefit contribution rate increased approximately 3.7% and 2.5%, effective primarily on August 1, 2023 and 2022, respectively.

​

The Asset-Based segment manages costs with shipment levels; however, a number of factors impact the efficiency of DSY tasks, including the effect of freight profile and mix changes, utilization of purchased transportation, and personnel efficiency. Changes in freight profile and mix, driven by dynamic LTL price-quoted shipments accounting for more of the total Asset-Based network shipments during the first half of 2023, impacted productivity and, combined with the impact of lower utilization of purchased transportation during the first nine months of 2023, resulted in a 1.9% decline in shipments per DSY hour for the three and nine months ended September 30, 2023. For the three and nine months ended

37

Table of Contents

September 30, 2023, the year-over-year increase in pounds per mile of 0.8% and 0.4%, respectively reflects improvement in linehaul productivity, partially offset by the impact of the changes in freight profile.

​

Fuel, supplies, and expenses as a percentage of revenue increased 0.1 percentage point and 0.6 percentage point during the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022, reflecting the impact of lower revenues, as these costs decreased $5.8 million and $4.7 million during the three and nine-month periods ended September 30, 2023, respectively. Fuel expense decreased during the 2023 periods, as the Asset-Based segment’s average fuel price per gallon (excluding taxes) decreased 18.0% and 20.0% for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022. For the nine months ended September 30, 2023, lower fuel costs were partially offset by increased repairs and maintenance costs. Delays in receiving new revenue equipment and higher market-driven costs to repair and maintain revenue equipment units have led to increased maintenance expenses during 2023, compared to 2022.

​

Depreciation and amortization as a percentage of revenue increased 0.6 percentage point and 0.4 percentage point for the three and nine-month periods ended September 30, 2023, respectively, compared to the same periods of 2022, as a result of receiving additional equipment at higher replacement costs during 2023.

​

Rents and purchased transportation as a percentage of revenue decreased 4.9 percentage points and 2.5 percentage points for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022, primarily due to focused reduction in the utilization of purchased transportation. Rail miles decreased approximately 21% and 10% for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022.

​

Gain (loss) on sale of property and equipment and lease impairment charges increased the Asset-Based segment operating ratio by 0.8 percentage point and 0.4 percentage point for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022. The three and nine months ended September 30, 2023 were impacted by a $0.7 million noncash lease-related impairment charge on a service center made available for sublease. The three- and nine-month periods ended September 30, 2022, included a $4.3 million gain on the like-kind exchange of a service center property and other gains on the sale of replaced equipment.

Asset-Light Operations

​

Asset-Light Segment Overview

​

Our Asset-Light segment is a key component of our strategy to offer a single source of integrated logistics solutions, designed to satisfy customers’ complex supply chain needs and unique shipping requirements. Asset-Light financial results previously included the ArcBest segment and FleetNet. In our discussion below, Asset-Light represents the reportable operating segment previously named ArcBest, exclusive of the discontinued operations of FleetNet, which sold on February 28, 2023, as previously discussed in the General section of MD&A.

​

We are focused on growing and making strategic investments in our Asset-Light segment that enhance our service offerings and strengthen our customer relationships. Throughout our operations, we are seeking opportunities to expand our revenues by deepening existing customer relationships, securing new customers, and adding capacity options for our customers. Our acquisition of MoLo, which was completed on November 1, 2021, accelerated the growth of our company by increasing the scale of truckload brokerage services offered within our Asset-Light segment and expanding our access to truckload capacity partners. We continue to develop our managed transportation solutions as part of our strategic efforts to cross-sell our service offerings and meet the demand for these services that include supply chain optimization. We expect to benefit from these and other strategic initiatives as we continue to deliver innovative solutions to customers.

​

The revenues of our Asset-Light operating segment generated approximately 36% and 37% of our total revenues before other revenues and intercompany eliminations for the three and nine months ended September 30, 2023, respectively, compared to approximately 39% and 42% for the same prior-year periods. The Asset-Light revenue decline for the three and nine months ended September 30, 2023, compared to the same prior-year periods reflects a softer market, which began in the second half of 2022.

Table of Contents

​

Our Asset-Light segment is affected by general economic conditions, as well as several other competitive factors that are more fully described in Item 1 (Business) and in Item 1A (Risk Factors) of Part I of our 2022 Annual Report on Form 10-K. See Note J to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for a description of the Asset-Light segment and additional segment information, including revenues, operating expenses, and operating income (loss) for the three and nine months ended September 30, 2023 and 2022.

​

The key indicators necessary to understand our Asset-Light operating segment are outlined below. These key indicators are used by management to evaluate segment operating performance and measure the effectiveness of strategic initiatives in the results of our Asset-Light segment. We quantify certain key indicators using key operating statistics which are important measures in analyzing segment operating results from period to period. These statistics are defined within the key indicators below and referred to throughout the discussion of the results of our Asset-Light segment:

​

| ● | Customer demand for logistics and premium transportation services combined with economic factors, which influence the number of shipments used to measure changes in business levels, primarily measured by:

​

Shipments per day – total shipments (excluding managed transportation solutions, as discussed below) divided by the number of working days during the period, compared to the same prior-year period.

​

| ● | Prices obtained for services, primarily measured by:

​

Revenue per shipment – total segment revenue divided by total segment shipments during the period (excluding managed transportation solutions, as discussed below), compared to the same prior-year period.

​

| ● | Availability of market capacity and cost of purchased transportation to fulfill customer shipments, with a measure of purchased transportation cost expressed as:

​

Purchased transportation costs as a percentage of revenue – the expense incurred for third-party transportation providers to haul or deliver freight during the period, divided by segment revenues for the period, expressed as a percentage.

​

| ● | Management of operating costs, primarily in the area of purchased transportation, with the total cost structure primarily measured by:

​

Operating ratio – the percent of operating expenses to revenue levels.

​

Presentation and discussion of the key operating statistics of revenue per shipment and shipments per day for the Asset-Light segment exclude statistical data of our managed transportation solutions transactions. Shipments for managed transportation solutions comprised 40% to 45% of the Asset-Light segment’s total shipments, while the business represented less than 20% of segment revenues, for the three and nine months ended September 30, 2023. Due to the nature of our managed transportation solutions, which typically involve a larger number of shipments at a significantly lower revenue per shipment level than the segment’s other service offerings, inclusion of the managed transportation solutions data would result in key operating statistics which are not representative of the operating results of the segment as a whole. As such, the key operating statistics management uses to evaluate performance of the Asset-Light segment exclude managed transportation services transactions.

​

Other companies within our industry may present different key performance indicators or they may calculate their key performance indicators differently; therefore, our key performance indicators may not be comparable to similarly titled measures of other companies. Key performance indicators should be viewed in addition to, and not as an alternative for, our reported results. Our key performance indicators should not be construed as better measurements of our results than operating income (loss), operating cash flow, net income, or earnings per share, as determined under GAAP.

(4) | The nine months ended September 30, 2022 includes a gain of $0.4 million recognized when funds were released from escrow in second quarter 2022 related to the May 2021 sale of the labor services portion of the Asset-Light segment’s moving business.

​

A comparison of key operating statistics for the Asset-Light segment, excluding managed transportation shipments, as previously defined in the Asset-Light Segment Overview section, is presented in the following table:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | Year Over Year % Change | ​

​

Asset-Light Revenues

Asset-Light segment revenues totaled $419.3 million and $1,267.2 million for the three and nine months ended September 30, 2023, respectively, compared to $515.2 million and $1,660.2 million for the same respective periods of 2022. The segment’s revenues decreased 18.6% and 23.7% for the three and nine months ended September 30, 2023, respectively, compared to the same prior-year periods. Current year results have been impacted by changes in business mix and lower average revenue per shipment associated with a softer market environment. Although average daily shipment levels increased despite weak market demand due to growth in the truckload business, lower shipment rates drove the reduction in revenue compared to the prior-year periods.

​

Asset-Light Operating Income (Loss)

The Asset-Light segment generated an operating loss of $3.7 million and $4.6 million for the three and nine months ended September 30, 2023, respectively. Operating results were impacted by lease-related impairment charges for certain office spaces made available for sublease, which increased expenses by $14.4 million for the three- and nine-month periods ended September 30, 2023. Changes in fair value of the contingent earnout consideration related to the MoLo acquisition reduced expenses by $17.8 million and $12.8 million in the three and the nine months ended September 30, 2023,

40

Table of Contents

respectively, compared to no adjustment for the three months ended September 30, 2022 and an increase in expense of $0.8 million for the nine months ended September 30, 2022. Operating income was $15.4 million and $64.0 million for the three and nine months ended September 30, 2022, respectively. The year-over-year decline in operating results reflects the decrease in revenues; the previously described impairment charges and changes in fair value; and changes in costs, primarily purchased transportation costs, as discussed in the following paragraphs.

​

Asset-Light Operating Expenses

Operating expenses decreased $76.8 million and $324.4 million for the three and nine months ended September 30, 2023, respectively, as purchased transportation buy rates steadily declined in the soft market environment. Employee-related and outside service cost reductions were implemented in second quarter 2023 and continued during third quarter 2023 to better align resources with business levels. Operating expenses as a percentage of revenue increased for the three and nine months ended September 30, 2023, due to lower revenue, partially offset by lower operating expenses including purchased transportation costs.

​

The segment’s purchased transportation costs as a percentage of revenue increased by 4.5 percentage points and 1.8 percentage points for the three and nine months ended September 30, 2023, respectively, compared to the same periods of 2022, reflecting lower revenue outpacing the reduction of purchased transportation costs in the 2023 periods, as previously discussed. Changes in market capacity impact the cost of purchased transportation and may not correspond to the timing of revisions to customer pricing and revenue per shipment. There can be no assurance that we will be able to secure prices from our customers that will allow us to maintain or improve our margins on the cost of sourcing carrier capacity.

​

Shared service costs as a percentage of revenue increased 0.4 percentage point and 1.8 percentage points for the three and nine months ended September 30, 2023, respectively, compared to the same prior-year periods, due to the effect of lower revenue. Shared service costs decreased for the three and nine months ended September 30, 2023, as employee costs were aligned to business levels; however, portions of operating expenses are fixed in nature and cost reductions can be limited as the segment strives to maintain customer service.

​

Lease-related impairment charges of $14.4 million recorded in the third quarter of 2023, as previously described, were 3.5 percentage points and 1.1 percentage points of revenue for the three and nine months ended September 30, 2023, respectively. The lease-related impairment charges are discussed further in Note B and Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

Contingent earnout consideration, as previously described, decreased as a percentage of revenue by 4.3 percentage points and 1.0 percentage point for the three and nine months ended September 30, 2023, respectively, compared to the same prior-year periods as remeasurements in 2023 considered the impact of the continued soft market environment on the achievement of earnout targets through 2025. The contingent earnout consideration is discussed further in Note B to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Asset-Light Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”)

We report our financial results in accordance with GAAP. However, management believes that certain non-GAAP performance measures and ratios, such as Adjusted EBITDA, which is utilized for internal analysis, provide analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. The use of certain non-GAAP measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management’s opinion, do not reflect our core operating performance. Management uses Adjusted EBITDA as a key measure of performance and for business planning. This measure is particularly meaningful for analysis of our Asset-Light segment, because it excludes amortization of acquired intangibles and software, changes in the fair value of contingent earnout consideration, and lease impairment charges, which are significant expenses resulting from strategic decisions rather than core daily operations. Management also believes Adjusted EBITDA to be relevant and useful information, as EBITDA is a standard measure commonly reported and widely used by analysts, investors, and others to measure financial performance of asset-light businesses and the ability to service debt obligations. Other companies may calculate Adjusted EBITDA differently; therefore, our calculation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. Adjusted EBITDA should not be construed as a better measurement than operating income (loss), operating cash flow, net income, or earnings per share, as determined under GAAP.

(1) | The calculation of Adjusted EBITDA as presented in this table begins with operating income (loss) as the most directly comparable GAAP measure. Other income (costs), income taxes, and net income are reported at the consolidated level and not included in the operating segment financial information evaluated by management to make operating decisions. Consolidated Adjusted EBITDA is reconciled to consolidated net income in the Consolidated Results section of Results of Operations.

(2) | Includes amortization of intangibles associated with acquired businesses which totaled $3.2 million and $9.6 million for the respective three- and nine-month periods ended in both September 30, 2023 and 2022 and is expected to total $12.8 million for full-year 2023, compared to $12.9 million in 2022.

(3) | Represents the change in fair value of the contingent earnout consideration recorded for the MoLo acquisition. The liability for contingent consideration is remeasured at each quarterly reporting date, and any change in fair value as a result of the recurring assessments is recognized in operating income (loss).

Current Economic Conditions

​

Economic conditions continue to be challenged by higher inflation levels and interest rates; supply chain challenges; a tight labor market; and geopolitical conflicts, including the Russia-Ukraine and Israel-Hamas wars. Recession risk remains elevated, though it is becoming increasingly possible for economic growth to slowly decelerate without causing a recessionary downturn as measured by U.S. real gross domestic product (“real GDP”). Manufacturing and home sales continued to contract in the first nine months of 2023, following the U.S. Federal Reserve’s implementation of a tighter

42

Table of Contents

monetary policy in March 2022 in an effort to curb inflation, which included rapidly increasing its targeted federal funds rate and reducing its security holdings.

​

Recent economic measures continue to indicate slowing economic activity despite third quarter 2023 economic growth exceeding expectations, which, combined with rising consumer prices, has created additional uncertainties in the global and U.S. economies and supply chains. According to the advance estimate released by the Bureau of Economic Analysis on October 26, 2023, real GDP increased at an annual rate of 4.9% for third quarter 2023. The Manufacturing Purchasing Managers’ Index (“Manufacturing PMI”), which is a leading indicator for demand in the freight transportation and logistics industry, was 46.7% for October 2023, compared to 50.2% in October 2022. The October 2023 Manufacturing PMI marks the twelfth month of economic contraction in the manufacturing sector following the 29-month period of growth in factory activity since the COVID-19 pandemic-related contractions in April and May 2020 and is the result of weak demand conditions and related low manufacturing outputs. The Industrial Production Index issued by the Federal Reserve increased at an annual rate of 2.5% for third quarter 2023. Our business has been impacted by the economic conditions indicated by these statistics as we respond to the softened economic environment, which resulted in decelerating demand trends in our existing customer-base for both Asset-Based and Asset-Light businesses during the first half of 2023. Market disruption caused by the shutdown of a large LTL competitor at the end of July 2023 resulted in an influx of demand for core, published LTL business during the third quarter of 2023. There can be no assurance that the economic environment, including the impact of rising interest rates on consumer demand, will be favorable for our freight services in future periods and that the impact of recent market disruptions will continue to positively impact demand for Asset-Based services.

​

Given uncertainties of current economic conditions, there can be no assurance that our estimates and assumptions, including those regarding the pricing environment and economic conditions, which are made for purposes of impairment tests related to operating assets and deferred tax assets, will prove to be accurate. Extended periods of economic disruption and resulting declines in industrial production and manufacturing and consumer spending could negatively impact demand for our services and have an adverse effect on our results of operations, financial condition, and cash flows. The softer market environment and available truckload capacity, which we experienced during the first nine months of 2023, resulted in a year-over-year decline in market pricing for many of our services, as compared to the first nine months of 2022. The previously mentioned market disruption in late July 2023 resulted in a decline in LTL industry carrier capacity. Our Asset-Based segment was able to secure additional core, published LTL-rated shipments at profitable rates. However, there can be no assurance that we will be able to continue to secure adequate prices from this new business or from our customers to maintain or improve our operating results. Significant declines in our business levels or other changes in cash flow assumptions or other factors that negatively impact the fair value of the operations of our reporting units could result in impairment and a resulting noncash write-off of a significant portion of the goodwill and intangible assets of our Asset-Light segment, which would have an adverse effect on our financial condition and operating results.

​

Effects of Inflation

​

Inflation remains above normal and historical levels. Global supply chain volatility and labor and energy shortages, in addition to the impact of federal programs and monetary policy, have elevated costs across a broad array of consumer goods. The year-over-year change in the consumer price index (“CPI”) declined to an increase of 3.7% before seasonal adjustment, in September 2023, slowing for the fifteenth consecutive month, a direct market response to the Federal Reserve’s tighter monetary policy implemented in March 2022. Inflation is impacted by energy prices, including petroleum products; shelter; and food prices, which have moderated in recent months while remaining elevated. Most of our expenses are affected by inflation, which generally results in increased operating costs. As such, there can be no assurances of the potential impact of inflationary conditions on our business, including demand for our transportation services.

​

Generally, inflationary increases in labor and fuel costs as they relate to our Asset-Based operations have historically been mostly offset through price increases and fuel surcharges. In periods of increasing fuel prices, the effect of higher associated fuel surcharges on the overall price to the customer influences our ability to obtain increases in base freight rates. In addition, certain nonstandard arrangements with some of our customers have limited the amount of fuel surcharge recovered. The timing and extent of base price increases on our Asset-Based revenues may not correspond with contractual increases in wage rates and other inflationary increases in cost elements and, as a result, could adversely impact our operating results. The Asset-Based segment’s ability to fully offset inflationary and contractual cost increases can be challenging during periods of recessionary and uncertain economic conditions.

​

Generally, inflationary increases in labor and operating costs related to our Asset-Light segment have historically been offset through price increases. The pricing environment, however, generally becomes more competitive during economic downturns, which may, as it has in the past, affect the ability to obtain price increases from customers both during and following such periods.

​

The impact of supply chain disruptions and component shortages has limited the availability and production of certain revenue equipment and certain other equipment used in our business operations. Consequently, the prices for these items have also increased. Partly as a result of inflationary pressures, our revenue equipment (tractors and trailers) has been and will very likely continue to be replaced at higher per-unit costs, which could result in higher depreciation charges on a per-unit basis. We consider these costs in setting our pricing policies, although the overall freight rate structure is governed by market forces. In addition to general effects of inflation, the motor carrier freight transportation industry faces rising costs related to compliance with government regulations on safety, equipment design and maintenance, driver utilization, emissions, and fuel economy.

​

Environmental and Legal Matters

​

We are subject to federal, state, and local environmental laws and regulations relating to, among other things: emissions control, transportation or handling of hazardous materials, underground and aboveground storage tanks, stormwater pollution prevention, contingency planning for spills of petroleum products, and disposal of waste oil. We may transport or arrange for the transportation of hazardous materials and explosives, and we operate in industrial areas where truck service centers and other industrial activities are located and where groundwater or other forms of environmental contamination could occur. In March 2023, ABF Freight entered into a Consent Decree with the Environmental Protection Agency (the “EPA”) to resolve alleged compliance issues under the federal Clean Water Act. As a result of the Consent Decree, ABF Freight paid a civil penalty of $0.5 million during the third quarter of 2023 and has agreed to certain compliance tasks. See Note K to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further discussion of the environmental matters to which we are subject, including additional detail on ABF Freight’s Consent Decree with the EPA.

​

Concern over climate change has led to legislative and regulatory efforts to limit carbon and other greenhouse gas (“GHG”) emissions, and we may incur significant costs to comply with increased regulation related to climate change in the future. Customers are increasingly focused on concerns related to climate change and demand for our services may be adversely impacted if we are less effective than our competitors in reducing or offsetting our GHG emissions. In consideration of the environmental impact of emissions from our operations, we are seeking more sustainable options for our equipment. We are piloting a small number of electric forklifts, electric yard tractors, and electric straight trucks at several ABF Freight service centers across our network. Electric tractors are significantly more expensive than new diesel tractors, and to comply with more stringent emissions standards, we expect the cost of our equipment, as well as our fuel and maintenance costs, will continue to increase in future periods. We are also investing in upgrades to our facilities, including energy efficient lighting, plumbing updates that lower our water usage, and other sustainability remodels and updates. To address our environmental impact in our city pickup and delivery operations, during 2021 and 2022, we built, tested and, with the help of a third-party leading provider of AI-enabled analytics and intelligence solutions, implemented City Route Optimization (“CRO”) technology that identifies opportunities to optimize routes and reduce emissions. During the first nine months of 2023, we made substantial progress towards the planned implementation of CRO at our service centers. We are targeting completion of the CRO implementation project in fourth quarter 2023.

​

Physical effects from climate change, including more severe weather events, have the potential to adversely impact our business levels, cause shipping delays or disruptions to our operations, increase our operating costs, and cause damage to our property and equipment. Due to the uncertainty of these matters, we cannot estimate the impact of climate-related developments on our operations or financial condition at this time. These and other matters related to climate change and the related risks to our business are further discussed in Part I, Item 1 (Business) and Part I, Item 1A (Risk Factors) of our 2022 Annual Report on Form 10-K. In addition to our focus on sustainability of our equipment and facilities, we continue our commitment to advance environmental, social and governance initiatives that are critical to our business and our customers’ businesses by investing in innovative technologies, developing our employees, and enhancing our capabilities and services for customers.

​

We are involved in various legal actions, the majority of which arise in the ordinary course of business. We maintain liability insurance against certain risks arising out of the normal course of our business, subject to certain self-insured retention limits. We routinely establish and review the adequacy of reserves for estimated legal, environmental, and self-insurance exposures. While management believes that amounts accrued in the consolidated financial statements are adequate, estimates of these liabilities may change as circumstances develop. Considering amounts recorded, routine legal matters are not expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

​

In January 2023, the Company and MoLo were named as defendants in lawsuits related to an auto accident involving one of MoLo’s contract carriers, which occurred prior to our acquisition of MoLo. Although we cannot estimate a range of reasonably possible losses for this matter at this time, it is reasonably possible that such amounts could be material to our financial condition, results of operations, or cash flows. See Note K to our consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further discussion of the legal matters in which we are currently involved.

​

As disclosed in Note K to our consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, the Company is working to settle a dispute relating to the classification between exempt and nonexempt status of MoLo employees. To date, no lawsuit has been filed. While the amount or range of reasonably possible losses for this matter cannot be estimated at this time, we believe that a loss related to this matter is reasonably possible. Such amounts could be material to our financial condition, results of operations, or cash flows.

​

Information Technology and Cybersecurity

​

We depend on the proper functioning, availability, and security of our information systems, including communications, data processing, financial, and operating systems, as well as proprietary software programs that are integral to the efficient operation of our business. Any significant failure or other disruption in our critical information systems, including denial of service, ransomware, and other cybersecurity attacks and incidents that impact the availability, reliability, speed, or other proper functioning of these systems or that result in proprietary information or sensitive or confidential data, including personal information of customers, employees and others, being compromised could have a significant impact on our operations. Any new or enhanced technology that we develop and implement may also be subject to cybersecurity attacks and may be prone to related incidents. We also utilize certain software applications provided by third parties; provide underlying data to third parties; grant access to certain of our systems to third parties who provide certain outsourced administrative functions or other services; and increasingly store and transmit data with our customers and third parties by means of connected information technology (“IT”) systems, any of which may increase the risk of a data privacy breach or other cybersecurity incident. Although we strive to carefully select our third-party vendors, we do not control their actions, and any problems caused by or impacting these third parties, including cyberattacks and security breaches at a vendor, could result in claims, litigation, losses, and/or liabilities and materially adversely affect our ability to provide service to our customers and otherwise conduct our business.

​

Our IT systems are protected through physical and software safeguards as well as backup systems considered appropriate by management. However, these systems are vulnerable to interruption by adverse weather conditions or natural disasters; power loss; telecommunications failures; terrorist attacks; internet failures and other disruptions to technology, including computer viruses; and other events beyond our control. It is not practicable to fully protect against the possibility of these events or cybersecurity attacks and other cyber events in every potential circumstance that may arise. To mitigate the potential for such occurrences at our primary data center, we have implemented various systems, including redundant telecommunication facilities; replication of critical data to an offsite location; fire suppression systems to protect our on-site data centers; and electrical power protection and generation facilities. We also have a catastrophic disaster recovery plan and alternate processing capability available for our critical data processes in the event of a catastrophe that renders one of our data centers unusable. A portion of our office personnel work remotely through hybrid and remote work arrangements, which may increase the demand for IT resources and our exposure to cybersecurity risks, including increased risks of phishing, an increased risk of unauthorized access to proprietary information or sensitive or confidential data, and increased risks of other cybersecurity attacks. We continue to implement physical and cybersecurity measures in an attempt to safeguard our systems in order to serve our operational needs in a remote working environment and to provide uninterrupted service to our customers. As a component of our cyber risk management program, we periodically engage a third-party provider to assess our cyber posture and assist us in improving our security profile. Over the next few months,

45

Table of Contents

we will be reviewing our processes around cybersecurity risk management and related governance framework and performing materiality assessments in order to comply with the new disclosure requirements.

​

Our property and cyber insurance would offset losses up to certain coverage limits in the event of a catastrophe or certain cyber incidents, including certain business interruption events related to these incidents; however, losses arising from a catastrophe or significant cyber incident may exceed our insurance coverage and could have a material adverse impact on our results of operations and financial condition. We do not have insurance coverage specific to losses resulting from a pandemic or geopolitical conflict. A significant disruption in our IT systems or a significant cybersecurity incident, including denial of service, system failure, security breach, intentional or inadvertent acts by employees or vendors with access to our systems or data, disruption by malware, or other damage, could interrupt or delay our operations, damage our reputation, cause a loss of customers, cause errors or delays in financial reporting, result in violation of privacy laws, expose us to a risk of loss or litigation, and/or cause us to incur significant time and expense to remedy such an event.

​

We have experienced incidents involving attempted denial of service attacks, malware attacks, and other events intended to disrupt information systems, wrongfully obtain valuable information, or cause other types of malicious events that could have resulted in harm to our business. To our knowledge, the various protections we have employed have been effective to date in identifying these types of events at a point when the impact on our business could be minimized. We continuously monitor and develop our IT networks and infrastructure to prevent, detect, address, and mitigate the risk of unauthorized access, misuse, computer viruses, and other events that could have a security impact. We have made and continue to make significant financial investments in technologies and processes to mitigate these risks. We also provide employee awareness training around phishing, malware, and other cyber risks. Despite our efforts, due to the increasing sophistication of cyber criminals and the development of new techniques for attack, we may be unable to anticipate or promptly detect, or implement adequate protective or remedial measures against, the activities of perpetrators of cyberattacks. Management is not aware of any current cybersecurity incident that has had a material effect on our operations, although there can be no assurances that a cyber incident that could have a material impact to our operations could not occur.

​

Liquidity and Capital Resources

​

Our primary sources of liquidity are cash, cash equivalents and short-term investments; cash generated by continuing operations; and borrowing capacity under our revolving credit facility or our accounts receivable securitization program.

​

Cash Flow and Short-Term Investments

​

Components of cash and cash equivalents and short-term investments, which are further described within Note B to our consolidated financial statements included in Part I, Item 1 of the Quarterly Report on Form 10-Q, were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | September 30 | ​ | December 31 |
​ | 2023 |  | 2022 |
​ | (in thousands) |
Cash and cash equivalents(1) | $ | 251,503 | ​ | $ | 158,264 | ​
Short-term investments |  | 89,326 | ​ |  | 167,662 | ​
Total | $ | 340,829 | ​ | $ | 325,926 | ​

​

(1) | Represents amounts from continuing operations. Balances reflect the reclassification of FleetNet amounts to discontinued operations.

​

Cash, cash equivalents and short-term investments increased $14.9 million from December 31, 2022 to September 30, 2023. Cash provided by operating activities during the nine months ended September 30, 2023 was $194.8 million, compared to $350.4 million in the same prior-year period. Net income for the nine months ended September 30, 2023 includes $93.4 million of net income from continuing operations and $53.3 million of net income from discontinued operations including the $52.3 million after-tax gain on the sale of FleetNet, net of transaction costs. Net income from continuing operations declined $164.8 million for the nine months ended September 30, 2023, compared to the same period of 2022, primarily due to the decline in operating income, as previously discussed in the Results of Operations.

46

Table of Contents

​

Our consolidated statements of cash flows presented for the nine months ended September 30, 2023 and 2022, include cash flows from continuing operations and the discontinued operations of FleetNet. Our discussions below segregate cash flows from continuing operations from those of discontinued operations for the nine-month periods ended September 30, 2023 and 2022.

​

Cash Flows from Continuing Operations

Changes in operating assets and liabilities, excluding income taxes, increased cash provided by operating activities by $17.4 million during the nine months ended September 30, 2023, while reducing cash provided by operating activities by $9.7 million during the nine months ended September 30, 2022. These changes were primarily due to a decrease in accounts receivable, partially offset by decreases in accounts payable and accrued expenses for the nine months ended September 30, 2023, and an increase in accounts receivable, partially offset by increases in accounts payable and accrued expenses for the nine months ended September 30, 2022.

​

The decreases in accounts receivable compared to increases in the prior-year period, were primarily due to improved collections of accounts receivable and lower business levels in our Asset-Light operating segment, in the nine-month period ended September 30, 2023. The decrease in accrued expenses and accounts payable at September 30, 2023 versus December 31, 2022, compared to the increase for the same prior-year period, was primarily related to higher payments in the first nine months of 2023 for certain union and nonunion performance-based incentive plans accrued at December 31, 2022, versus the payments in the first nine months of 2022 for accruals as of December 31, 2021, as well as lower business levels in our Asset-Light operating segment.

​

Cash provided by investing activities was impacted by $100.9 million of proceeds from the sale of FleetNet, as further discussed in the General section of MD&A. During the nine-month period ended September 30, 2023, we spent $123.7 million on capital expenditures, net of financings and proceeds from asset sales, including property purchases and the renovation of properties for our Asset-Based network. See Capital Expenditures below for estimated annual expenditure amounts for 2023.

​

We have financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements. Cash used to fund these promissory note payments during the nine months ended September 30, 2023, was $52.5 million. During the nine months ended September 30, 2023, we repurchased 688,502 shares of our common stock under our share repurchase program for an aggregate cost of $65.9 million. We also continued to return capital to our shareholders with our quarterly dividend payments, which totaled $8.7 million during the nine months ended September 30, 2023. Our dividends and share repurchase program are further discussed in Other Liquidity below.

​

Cash Flows from Discontinued Operations

Net cash provided by operating activities of discontinued operations was $0.8 million during both the nine months ended September 30, 2023 and 2022, reflecting the routine operations of FleetNet. Net cash used in investing activities of discontinued operations was $0.4 million and $2.8 million for the nine months ended September 30, 2023 and 2022, respectively. Net cash used in financing activities of discontinued operations was $0.5 million for the nine months ended September 30, 2023, compared to net cash provided by financing activities of $2.0 million for the same prior-year period. Net cash of discontinued operations for both investing and financing activities did not have a material effect on the operations disclosed in Note C to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. Net cash activity for FleetNet has not materially impacted our operations in recent years, nor is the absence of cash flows from the discontinued operations of FleetNet expected to affect future liquidity or capital resources.

​

Financing Arrangements

​

We financed the purchase of $31.0 million of revenue equipment through notes payable during the nine months ended September 30, 2023. Future payments due under our notes payable totaled $207.4 million, including interest, as of September 30, 2023, for a decrease of $21.7 million from December 31, 2022.

​

Our financing arrangements and the scheduled maturities of our long-term debt obligations, are disclosed in Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

Contractual Obligations

​

We have purchase obligations, consisting of authorizations to purchase and binding agreements with vendors, relating to revenue equipment used in our Asset-Based and Asset-Light operations, other equipment, facility improvements, software, service contracts, and other items for which amounts were not accrued in the consolidated balance sheet as of September 30, 2023. These purchase obligations totaled $166.5 million as of September 30, 2023, with $158.0 million expected to be paid within the next year, provided that vendors complete their commitments to us. As of September 30, 2023, the amount of our purchase obligations has increased $65.6 million from December 31, 2022, primarily related to revenue equipment, which is included in our 2023 capital expenditure plan.

​

As of September 30, 2023, contractual obligations for operating lease liabilities, primarily related to our Asset-Based service centers, totaled $290.2 million, including imputed interest, for an increase of $57.4 million from December 31, 2022. The scheduled maturities of our operating lease liabilities as of September 30, 2023, are disclosed in Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10 Q. There have been no other material changes in the contractual obligations disclosed in our 2022 Annual Report on Form 10-K during the nine months ended September 30, 2023. We have no investments, loans, or any other known contractual arrangements with unconsolidated special-purpose entities, variable interest entities, or financial partnerships, and we have no outstanding loans with executive officers or directors.

​

Capital Expenditures

​

Our total capital expenditures for 2023, including amounts financed, are estimated to range from $270.0 million to $285.0 million, net of asset sales, which is slightly lower than the second quarter 2023 estimated range. These estimated expenditures include revenue equipment purchases of approximately $150.0 million, primarily for our Asset-Based operations, including $60.0 million of equipment purchases previously planned for 2022, which were delayed due to supply chain-related manufacturing delays and cancellations and carried over to our 2023 planned expenditures. The remainder of our 2023 expected capital expenditures includes investments in real estate and facility upgrades to support growth plans, as well as technology investments across the enterprise and miscellaneous dock equipment upgrades and enhancements. Depreciation and amortization expense, excluding amortization of intangibles, is estimated to be approximately $120.0 million in 2023. The amortization of intangible assets is estimated to be approximately $13.0 million in 2023, primarily related to purchase accounting amortization associated with the MoLo acquisition.

​

Other Liquidity Information

​

General economic conditions, including the impact of the geopolitical conflicts, competitive market factors, rising interest rates as a result of monetary policy and volatile energy prices, and the related impact on our business (primarily tonnage and shipment levels and the pricing that we receive for our services in future periods) could affect our ability to generate cash from operating activities and maintain cash, cash equivalents, and short-term investments on hand. Cash, cash equivalents, and short-term investments totaled $340.8 million at September 30, 2023. Our revolving credit facility and our accounts receivable securitization program provide available sources of liquidity with flexible borrowing and payment options. We had available borrowing capacity under our revolving credit facility and our accounts receivable securitization program of $200.0 million and $40.0 million, respectively, as of September 30, 2023. We believe that these agreements provide borrowing capacity necessary for growth of our businesses. During the next 12 months and for the foreseeable future, we believe existing cash, cash equivalents, short-term investments, cash generated by operating activities, and amounts available under our revolving credit facility or our accounts receivable securitization program will be sufficient to finance our operating expenses; fund our ongoing initiatives to grow our business, including investments in technology; repay amounts due under our financing arrangements; and pay the contingent earnout consideration related to the MoLo acquisition as it is earned. Notes payable, finance leases, and other secured financing may also be used to fund capital expenditures, provided that such arrangements are available and the terms are acceptable to us.

​

The Agreement and Plan of Merger (the “Merger Agreement”) for our acquisition of MoLo provides for additional cash consideration ranging from 44% to 212% of the target payment relative to the achievement of incremental adjusted earnings before interest, taxes, depreciation, and amortization (“EBITDA”) targets of 80% to 300% for years 2023 through

48

Table of Contents

2025. The cumulative additional consideration through 2025 would be $215.0 million at 100% of the target, consisting of target earnout payments of $45.0 million, $70.0 million, and $100.0 million for the years ended December 31, 2023, 2024, and 2025, respectively. The contingent earnout consideration is remeasured at each quarterly reporting date and any change in fair value as a result of the recurring assessments is recognized in operating income. As of September 30, 2023, we do not expect the target earnout for 2023 to be met. As such, the current portion of the liability for contingent earnout consideration was reduced to zero following the second quarter remeasurement. The long-term liability for contingent earnout consideration was reduced as a result of the third quarter remeasurement, based on lower earnings anticipated for 2024 as a result of continued soft market conditions. Due to the cumulative nature of the consideration arrangement, amounts relating to 2023 and 2024 earnings could be payable through the catch-up period ending December 31, 2025 if the applicable targets are achieved. As of September 30, 2023, the fair value of contingent earnout consideration is estimated to be $99.2 million, representing the estimated present value of the earnout, as defined, based on Level 3 valuation techniques as disclosed in Note B to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

We continue to take actions to enhance shareholder value with our quarterly dividend payments and treasury stock purchases. On October 25, 2023, we announced our Board of Directors declared a dividend of $0.12 per share to stockholders of record as of November 8, 2023. We expect to continue to pay quarterly dividends on our common stock in the foreseeable future, although there can be no assurance in this regard since future dividends will be at the discretion of the Board of Directors and are dependent upon our future earnings, capital requirements, and financial condition; contractual restrictions applying to the payment of dividends under our Credit Agreement; and other factors.

​

In February 2023, our Board of Directors increased the total amount available for purchases of our common stock under our share repurchase program to $125.0 million. In March 2023, we executed a 10b5-1 plan for stock repurchases during our closed trading window extending from March 16, 2023 to May 2, 2023. In September 2023, we executed a second 10b5-1 plan for stock repurchases during our closed trading window extending from September 18, 2023 to October 31, 2023. During the nine months ended September 30, 2023, we purchased 688,502 shares of our common stock for an aggregate cost of $65.9 million, including 348,799 shares for an aggregate cost of $32.3 million under both 10b5-1 plans. The sale of FleetNet supports the return of capital to ArcBest’s shareholders, as a large portion of the sale proceeds have been used to fund our share repurchases. As of September 30, 2023, $59.1 million remained available under the share repurchase program (see Note H to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q).

​

Financial Instruments

​

We have an interest rate swap agreement in place, which is further discussed in Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. As of September 30, 2023, we have no other derivative or hedging arrangements outstanding.

​

Balance Sheet Changes

​

Accounts Receivable

Accounts receivable decreased $48.0 million from December 31, 2022 to September 30, 2023, reflecting improved collections and lower revenue levels in September 2023 compared to December 2022, as previously discussed in the Results of Operations.

​

Prepaid and Refundable Income Taxes and Income Taxes Payable

Prepaid and refundable income taxes increased $7.3 million and income taxes payable decreased $14.6 million from December 31, 2022 to September 30, 2023, reflecting net tax payments in excess of tax accruals.

​

49

Table of Contents

Operating Right-of-Use Assets and Operating Lease Liabilities

The decrease in operating right-of-use assets of $2.4 million was primarily related to lease impairment charges recognized during the third quarter of 2023, as previously discussed, which reduced the carrying value of the related right-of-use assets and leasehold improvements to the estimated fair value at September 30, 2023, partially offset by new leases. The increase in operating lease liabilities, including current portion, of $29.1 million from December 31, 2022 to September 30, 2023, was primarily due to new leases and lease renewals during the nine months ended September 30, 2023.

​

Accounts Payable

Accounts payable decreased $24.0 million from December 31, 2022 to September 30, 2023, primarily due to the decrease in Asset-Light business levels.

​

Accrued Expenses

Accrued expenses decreased $15.6 million from December 31, 2022 to September 30, 2023, primarily due to payments during the first nine months of 2023 of amounts accrued at December 31, 2022 for certain performance-based incentive plans and contributions to our defined contribution plan, offset partially by increases in wage and vacation accruals due primarily to higher wages and headcount, and higher workers’ compensation and third-party casualty reserves due to an increase in claims activity and higher average claims costs.

​

Long-term Debt

The $21.5 million decrease in long-term debt, including current portion, from December 31, 2022 to September 30, 2023 is primarily due to payments on notes payable of $52.5 million, net of equipment financed of $31.0 million.

​

Contingent Consideration

The contingent earnout consideration related to the MoLo acquisition, which is previously described within the Other Liquidity section, is remeasured at each quarterly reporting date and any change in fair value as a result of the recurring assessments is recognized in operating income. The liability for contingent earnout consideration decreased $12.8 million from December 31, 2022 to September 30, 2023, due to the net decrease in fair value following remeasurements during the first nine months of 2023.

​

Deferred Income Taxes

Deferred income tax liabilities decreased $10.1 million from December 31, 2022 to September 30, 2023, primarily due to the gain on sale of FleetNet, changes in certain accrued expenses reserves, and lease impairment charges related to the reduced carrying value of operating right-of-use assets, net of the decrease in contingent consideration during the first nine months of 2023.

​

​

Income Taxes

​

Our effective tax rate for continuing operations was 25.5% and 21.6% for the three and nine months ended September 30, 2023, respectively, compared to 22.6% and 23.3% for the same periods of 2022. The federal statutory tax rate is 21.0% and the average state tax rate, net of the associated federal deduction, is approximately 5%. However, various factors and significant changes in nondeductible expenses, the cash surrender value of life insurance, the federal alternative fuel tax credit and the settlement of share-based payment awards primarily vesting in the second quarter, may cause the full-year 2023 tax rate to vary significantly from the statutory rate.

​

At September 30, 2023, we had $42.8 million of net deferred tax liabilities after valuation allowances. We evaluated the need for a valuation allowance for deferred tax assets at September 30, 2023 by considering the future reversal of existing taxable temporary differences, future taxable income, and available tax planning strategies. Valuation allowances for deferred tax assets totaled $1.8 million and $1.7 million at September 30, 2023 and December 31, 2022, respectively. As of September 30, 2023, deferred tax liabilities which will reverse in future years exceeded deferred tax assets.

​

Financial reporting income may differ significantly from taxable income because of items such as contingent earnout consideration, prepaid expenses, accelerated depreciation for tax purposes, gains and losses on sales of assets, impairment of leases, and a significant number of liabilities such as vacation pay, workers’ compensation and third-party casualty claims, and other liabilities, which, for tax purposes, are generally deductible only when paid. For the nine months ended September 30, 2023 and 2022, income determined under income tax law exceeded financial reporting income.

​

During the nine months ended September 30, 2023, we made federal, state, and foreign tax payments of $78.3 million, and received refunds of $1.7 million of federal and state income taxes that were paid in prior years. Management does not expect the cash outlays for income taxes will materially exceed reported income tax expense for the foreseeable future.

​

The Company’s total effective tax rate was 23.1% and 23.3% for the nine months ended September 30, 2023 and 2022, respectively, including discontinued operations, which are further discussed in Note C to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. Income tax expense reflected in discontinued operations was a tax benefit of less than $0.1 million, or an effective tax benefit rate of 25.5%, and income tax expense of $18.3 million, or an effective tax rate of 25.5%, for the three and nine months ended September 30, 2023, respectively, which primarily consisted of federal and state income taxes on the gain on the sale of FleetNet. For the three and nine months ended September 30, 2022, income tax expense reflected in discontinued operations was $0.2 million, or an effective tax rate of 49.1%, and $1.1 million, or an effective tax rate of 27.9%, respectively.

Critical Accounting Policies

​

The accounting policies that are “critical,” or the most important, to understand our financial condition and results of operations and that require management to make the most difficult judgments are described in our 2022 Annual Report on Form 10-K. There have been no updates to our critical accounting policies during the nine months ended September 30, 2023. Management believes that there is no new accounting guidance issued but not yet effective that will impact our critical accounting policies.

Certain statements and information in this report may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including, among others, statements regarding (i) our expectations about our intrinsic value or our prospects for growth and value creation and (ii) our financial outlook, position, strategies, goals, and expectations. Terms such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “foresee,” “intend,” “may,” “plan,” “predict,” “project,” “scheduled,” “should,” “would,” and similar expressions and the negatives of such terms are intended to identify forward-looking statements. These statements are based on management’s beliefs, assumptions, and expectations based on currently available information, are not guarantees of future performance, and involve certain risks and uncertainties (some of which are beyond our control). Although we believe that the expectations reflected in these forward-looking statements are reasonable as and when made, we cannot provide assurance that our expectations will prove to be correct. Actual outcomes and results could materially differ from what is expressed, implied, or forecasted in these statements due to a number of factors, including, but not limited to: the effects of a widespread outbreak of an illness or disease, including the COVID-19 pandemic, or any other public health crisis, as well as regulatory measures implemented in response to such events; external events which may adversely affect us or the third parties who provide services for us, for which our business continuity plans may not adequately prepare us, including, but not limited to, acts of war or terrorism, or military conflicts; data privacy breaches, cybersecurity incidents, and/or failures of our information systems, including disruptions or failures of services essential to our operations or upon which our information technology platforms rely; interruption or failure of third-party software or information technology systems or licenses; untimely or ineffective development and implementation of, or failure to realize the potential benefits associated with, new or enhanced technology or processes, including the freight handling pilot test program at ABF Freight and our customer pilot offering of Vaux, including human-centered remote operation software; the loss or reduction of business from large customers; the timing and performance of growth initiatives and the ability to manage our cost structure; the cost, integration, and performance of any recent or future acquisitions, including the acquisition of MoLo Solutions, LLC, and the inability to realize the anticipated benefits of the acquisition within the expected time period or at all; maintaining our corporate reputation and intellectual property rights; nationwide or global disruption in the supply chain resulting in increased volatility in freight volumes; competitive initiatives and pricing pressures; increased prices for and decreased availability of new revenue equipment, decreases in value of used revenue equipment, and higher costs of equipment-related operating expenses such as maintenance, fuel, and related taxes; availability of fuel, the effect of volatility in fuel prices and the associated changes in fuel surcharges on securing increases in base freight rates, and the inability to collect fuel surcharges; relationships with employees, including unions, and our ability to attract, retain, and upskill employees; unfavorable terms of, or the inability to reach agreement on, future collective bargaining agreements or a workforce stoppage by our employees covered under ABF Freight’s collective bargaining agreement; union employee wages and benefits, including changes in required contributions to multiemployer plans; availability and cost of reliable third-party services; our ability to secure independent owner operators and/or operational or regulatory issues related to our use of their services; litigation or claims asserted against us; governmental regulations; environmental laws and regulations, including emissions-control regulations; default on covenants of financing arrangements and the availability and terms of future financing arrangements; our ability to generate sufficient cash from operations to support significant ongoing capital expenditure requirements and other business initiatives; self-insurance claims and insurance premium costs; potential impairment of goodwill and intangible assets; general economic conditions and related shifts in market demand that impact the performance and needs of industries we serve and/or limit our customers’ access to adequate financial resources; increasing costs due to inflation and rising interest rates; seasonal fluctuations, adverse weather conditions, natural disasters, and climate change; and other financial, operational, and legal risks and uncertainties detailed from time to time in ArcBest Corporation’s public filings with the Securities and Exchange Commission (“SEC”).

ITEM 3. QUANTITATIVE AND QUALITATIV E DISCLOSURES ABOUT MARKET RISK

​

Our primary market risk results from fluctuations in interest rates primarily resulting from our debt portfolio. Our debt portfolio includes notes payable with a fixed rate of interest, which mitigates the impact of fluctuations in interest rates. Future issuances of long-term debt could be impacted by increases in interest rates, which could result in higher interest costs. Borrowings under our revolving credit facility and accounts receivable securitization program are at a variable interest rate and expose us to the risk of increasing interest rates. We currently utilize an interest rate swap agreement to mitigate a portion of our interest rate risk under our revolving credit facility. See Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further discussion of our interest rates.

​

Discussion of current economic conditions and related impact on our business can be found in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in this Quarterly Report on Form 10-Q.

​

There have been no other significant changes in the Company’s market risks as reported in the Company’s 2022 Annual Report on Form 10-K since December 31, 2022.

​

​

ITEM 4. CONTROLS AND PROCEDURE S

​

As of the end of the period covered by this report, an evaluation was performed with the participation of the Company’s management, including the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on that evaluation, the Company’s management, including the Principal Executive Officer and Principal Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2023.

​

There were no changes in the Company’s internal controls over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.
