NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

​

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

​

ArcBest Corporation™ (the “Company”) is the parent holding company of freight transportation and integrated logistics businesses providing innovative solutions. The Company’s operations are conducted through its three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); ArcBest, the Company’s asset-light logistics operation; and FleetNet. 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 65% of the Company’s total revenues before other revenues and intercompany eliminations for the six months ended June 30, 2021. As of June 2021, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2018 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023.

​

Financial Statement Presentation

​

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 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 2020 Annual Report on Form 10-K 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. The Company considered the impact of the novel coronavirus (“COVID-19”) pandemic on the estimates and assumptions used in preparation of the Company’s consolidated financial statements as of and for the three and six months ended June 30, 2021. Given the uncertainties regarding the economic environment and the impact of the COVID-19 pandemic on our business, it is possible that these estimates and assumptions may materially change in future periods.

​

Adopted Accounting Pronouncements

​

ASC Topic 740, Income Taxes, was amended to simplify the accounting for income taxes to improve consistency of accounting methods and remove certain exceptions. The amendment was effective for the Company on January 1, 2021, and did not impact the consolidated financial statements and disclosures.

​

Accounting Pronouncements Not Yet Adopted

​

Management believes there is no new accounting guidance issued but not yet effective that is relevant to the Company’s current financial statements.

NOTE B – FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

​

Financial Instruments

​

The following table presents the components of cash and cash equivalents and short-term investments:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | June 30 |  | December 31 |
​ | ​ | 2021 | ​ | 2020 |
​ | ​ | (in thousands) | ​

Money market funds(3) | ​ |  | 49,101 | ​ |  | 34,201 | ​
Total cash and cash equivalents | ​ | $ | 362,619 | ​ | $ | 303,954 | ​

Short-term investments | ​ | ​ | ​ | ​ | ​ | ​ | ​
Certificates of deposit(1) | ​ | $ | 59,967 | ​ | $ | 53,297 | ​
U.S. Treasury securities(4) | ​ | ​ | — | ​ | ​ | 12,111 | ​
Total short-term investments | ​ | $ | 59,967 | ​ | $ | 65,408 | ​

​

(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 primarily in FDIC-insured accounts and placing its short-term investments primarily in FDIC-insured certificates of deposit. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At June 30, 2021 and December 31, 2020, cash, cash equivalents, and short-term investments totaling $132.5 million and $156.4 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

​

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.

​ | ​ | $ | 258,807 | ​ | $ | 264,340 | ​ | $ | 305,623 | ​ | $ | 312,749 | ​

​

(1) | The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on LIBOR, plus a margin, that is considered to be 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 (see in Note I to the consolidated financial statements in Item 8 of the Company’s 2020 Annual Report on Form 10-K). 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 3.1% and 2.6% at June 30, 2021 and December 31, 2020, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). Included in other long-term liabilities with the current portion included in accrued expenses.

NOTE D – INCOME TAXES

​

The effective tax rate was 17.0% and 19.5% for the three and six months ended June 30, 2021, respectively. The effective tax rate was 23.4% and 23.1% for the three and six months ended June 30, 2020, respectively. 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 six months ended June 30, 2021, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from state income taxes, nondeductible expenses, changes in the cash surrender value of life insurance, federal research and development tax credits, changes in tax valuation allowances, and tax benefit from the vesting of stock awards. For the three and six months ended June 30, 2020, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from state income taxes, nondeductible expenses, changes in the cash surrender value of life insurance, federal alternative fuel and research development tax credits, changes in valuation allowances, and the tax expense from the vesting stock awards. The Company’s effective tax rate for the six months ended June 30, 2020 was also impacted by the reversal of an uncertain tax position.

​

As of June 30, 2021, 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 June 30, 2021 and concluded that, other than for certain deferred tax assets related to foreign and state tax credit carryforwards and federal 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 $1.4 million and $1.3 million at June 30, 2021 and December 31, 2020, respectively.

​

The Company paid federal, state, and foreign income taxes of $15.3 million during the six months ended June 30, 2021, and paid foreign and state income taxes of $2.3 million during the six months ended June 30, 2020. The Company received refunds of federal and state income taxes that were paid in prior years of less than $0.1 million and $0.4 million during the six months ended June 30, 2021 and 2020, respectively.

Financing Arrangements

​

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its Third Amended and Restated Credit Agreement (the “Credit Agreement”) with an initial maximum credit amount of $250.0 million, including a swing line facility in an aggregate amount of up to $25.0 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 certain additional conditions as provided in the Credit Agreement. In June 2021, the Company repaid $20.0 million of borrowings under the Credit Facility. As of June 30, 2021, standby letters of credit of $0.6 million have been issued under the Credit Facility, which reduced the available borrowing capacity to $199.4 million under the initial maximum credit amount of the Credit Facility, as of June 30, 2021.

​

Principal payments under the Credit Facility are due upon maturity of the facility on October 1, 2024; 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. 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, purchases and sales of assets, and certain restricted payments. The Company was in compliance with the covenants under the Credit Agreement at June 30, 2021.

​

Interest Rate Swaps

The Company has an interest rate swap agreement with a $50.0 million notional amount which started on January 2, 2020 and will mature on June 30, 2022. The Company receives floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.99% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.12% based on the margin of the Credit Facility as of June 30, 2021. The fair value of the interest rate swap of $1.0 million and $1.4 million was recorded in other long-term liabilities in the consolidated balance sheet at June 30, 2021 and December 31, 2020, respectively.

​

The Company also has an interest rate swap agreement with a $50.0 million notional amount which will start on June 30, 2022 and mature on October 1, 2024. The Company will receive floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 0.43% beginning on June 30, 2022 throughout the remaining term of the agreement. From June 30, 2022 to October 1, 2024, the extended interest rate swap agreement will effectively convert the $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 1.56% based on the margin of the Credit Facility as of June 30, 2021. The fair value of the interest rate swap of $0.4 million was recorded in other long-term assets and $0.2 million was recorded in other long-term liabilities in the consolidated balance sheet at June 30, 2021 and December 31, 2020, respectively.

​

The unrealized gain or loss on the interest rate swap instruments was reported as a component of accumulated other comprehensive income, net of tax, in stockholders’ equity at June 30, 2021 and December 31, 2020, and the change in the unrealized loss on the interest rate swaps for the three and six months ended June 30, 2021 and 2020 was reported in other comprehensive income (loss), net of tax, in the consolidated statements of comprehensive income. The interest rate swaps are 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 agreements at June 30, 2021.

​

Accounts Receivable Securitization Program

In June 2021, the Company amended and restated its accounts receivable securitization program. The amendment extended the maturity date of this program from October 1, 2021 to July 1, 2024, decreased the amount of available cash proceeds under the facility from $125.0 million to $50.0 million and increased the amount of additional borrowings the Company may request under the accordion feature from $25.0 million to $100.0 million, subject to certain conditions.

​

15

Table of Contents

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 lender’s interest in the trade accounts receivables. Borrowings under the accounts receivable securitization program bear interest based upon LIBOR, 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 June 30, 2021.

​

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 June 30, 2021, standby letters of credit of $10.1 million have been issued under the program, which reduced the available borrowing capacity to $39.9 million.

​

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2021, the Company had letters of credit outstanding of $11.2 million (including $10.1 million issued under the accounts receivable securitization program and $0.6 million issued under the Credit Facility). 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 June 30, 2021, surety bonds outstanding related to the self-insurance program totaled $61.6 million.

​

Notes Payable

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $8.1 million for revenue equipment during the three months ended June 30, 2021.

​

Subsequent to June 30, 2021, the Company financed the purchase of an additional $12.9 million of revenue equipment through promissory note arrangements as of August 2, 2021.

Multiemployer Plans

​

ABF Freight System, Inc. and certain other subsidiaries reported in the Company’s Asset-Based operating segment (“ABF Freight”) contribute to multiemployer pension and health and welfare plans, which have been established pursuant to the Taft-Hartley Act, to provide benefits for its contractual employees. The 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. Contributions to these plans are based generally on the time worked by ABF Freight’s contractual employees at rates specified in the 2018 ABF NMFA and other related supplemental agreements. ABF Freight recognizes as expense the contractually required contributions for each period and recognizes as a liability any contributions due and unpaid. The funding obligations to the multiemployer pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006, which was permanently extended by the Multiemployer Pension Reform Act (the “Reform Act”) included in the Consolidated and Further Continuing Appropriations Act of 2015.

​

Approximately one half of ABF Freight’s total contributions to multiemployer pension plans are made to the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”). As set forth in the 2020 Annual Funding Notice for the Central States Pension Plan, the funded percentage of the plan was 19.5% as of January 1, 2020. In the Notice of Critical and Declining Status for the Central States Pension Plan dated March 31, 2021, the plan’s actuary certified that the plan is in critical and declining status, as defined by the Reform Act, for the plan year beginning January 1, 2021. Critical and declining status is applicable to critical status plans that are projected to become insolvent anytime within the next 14 plan years, or if the plan is projected to become insolvent within the next 19 plan years and

either the plan’s ratio of inactive participants to active participants exceeds two to one or the plan’s funded percentage is less than 80%.

​

On March 11, 2021, H.R.1319, the American Rescue Plan Act of 2021 (the “American Rescue Plan Act”) was signed into law. The American Rescue Plan Act includes the Butch Lewis Emergency Pension Plan Relief Act of 2021 (the “Pension Relief Act”). The Pension Relief Act includes provisions to improve funding for multiemployer pension plans, including financial assistance provided through the Pension Benefit Guarantee Corporation (the “PBGC”) to qualifying underfunded plans to secure pension benefits for plan participants. Without the funding to be provided by the Pension Relief Act, many of the multiemployer pension funds to which ABF Freight contributes, including the Central States Pension Plan, could become insolvent in the near future; however, ABF Freight would continue to be obligated to make contributions to those funds under the terms of the 2018 ABF NMFA.

​

On July 9, 2021, the PBGC announced an interim final rule implementing a Special Financial Assistance Program (the “SFA Program”) to administer funds to severely underfunded eligible multiemployer pension plans under the Pension Relief Act. The Company is currently evaluating the impact of the assistance to be provided by the SFA Program to the multiemployer pension plans to which ABF Freight contributes. Through the term of the 2018 ABF NMFA, which extends through June 30, 2023, ABF Freight’s multiemployer pension contribution obligations generally will be satisfied by making the specified contributions when due. Future contribution rates will be determined through the negotiation process for contract periods following the term of the current collective bargaining agreement. While the Company cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees, management believes future contribution rates to multiemployer pension plans may be less likely to increase as a result of the provisions of the Pension Relief Act. If ABF Freight was to completely withdraw from certain multiemployer pension plans, under current law, ABF Freight would have material liabilities for its share of the unfunded vested liabilities of each such plan.

​

The multiemployer plan administrators have provided to the Company no other significant changes in information related to multiemployer plans from the information disclosed in the Company’s 2020 Annual Report on Form 10-K.

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, and key operating statistics to evaluate performance and allocate resources to the Company’s operations.

​

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage, shipment or service event 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. The COVID-19 pandemic had a significant negative impact on demand for the Company’s services during the three months ended June 30, 2020, resulting in lower tonnage, shipment, and service event levels and, consequently, lower segment revenues for the second quarter of 2020. As a result, the Company’s operating segment information for the three months ended June 30, 2020 does not reflect typical seasonal trends in business levels as described below for the Company’s reportable operating segments.

​

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 ArcBest segment, including freight transportation related to certain consumer household goods self-move services.

​

Freight shipments and operating costs of the Asset-Based segment can be adversely affected by inclement weather conditions. The second and third calendar quarters of each year usually have the highest tonnage 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, and the impact of other adverse external events or conditions, including the COVID-19 pandemic, may influence quarterly freight tonnage levels.

​

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

​

ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains. The second and third calendar quarters of each year usually have the highest 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, and the impact of other adverse external events or conditions, including the COVID-19 pandemic, may impact quarterly business levels. Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

​

| ● | FleetNet includes the results of operations of FleetNet America, Inc. and certain other subsidiaries that provide roadside assistance and maintenance management services for commercial vehicles through a network of third-party service providers. FleetNet provides services to the Asset-Based and ArcBest segments.

​

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume and the impact of other external events or conditions, including the COVID-19 pandemic.

21

Table of Contents

​

The Company’s other business activities and operating segments that are not reportable include ArcBest Corporation and certain other subsidiaries. Certain costs incurred by the parent holding company and the Company’s shared services subsidiary are allocated to the reporting segments. The Company eliminates intercompany transactions in consolidation. However, the information used by the Company’s management with respect to its reportable 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 ArcBest Board of Directors, and certain technology investments. Shared services costs attributable to the operating segments are predominantly allocated based upon estimated and planned resource utilization-related metrics such as estimated shipment levels, number of pricing proposals, or number of personnel supported. The bases for such charges are modified and adjusted by management when necessary or appropriate to reflect fairly and equitably the actual incidence of cost incurred by the 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.

​

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, 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 an accrual which is included in accrued expenses in the consolidated balance sheets, 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.

​

Certain Asset-Based service center facilities operate with no exposure certifications or stormwater permits under the federal Clean Water Act (“the CWA”). The no exposure certification and stormwater permits may require periodic facility inspections and monitoring and reporting of stormwater sampling results. The Company determined that certain procedures regarding sampling, documentation, and reporting were not appropriately being performed in accordance with the CWA. As such, the Company self-reported the matter to the EPA. An estimated settlement expense for this matter is accrued within accrued expenses in the consolidated balance sheet as of June 30, 2021. Resolution of this matter is not expected to have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.

​

Other Events

​

In February 2021, the Company received a Notice of Assessment from a 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 the assessment and filed an appeal in May 2021. The Company has previously accrued an amount related to this assessment consistent with applicable accounting guidance, but if the state prevails in its position, the Company may owe additional tax. Management does not believe the amount involved will have a material adverse effect on 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 CorporationTM (together with its subsidiaries, the “Company,” “we,” “us,” and “our”) provides a comprehensive suite of freight transportation and integrated logistics services to deliver innovative solutions. Our operations are conducted through our three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); ArcBest, our asset-light logistics operation; and FleetNet. The ArcBest and the FleetNet reportable segments combined represent our Asset-Light operations. 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.

​

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, 2020. Our 2020 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.

Our consolidated revenues, which totaled $949.0 million and $1,778.2 million for the three and six months ended June 30, 2021, respectively, increased 51.3% and 33.8%, respectively, compared to the same prior-year periods. The revenue growth was attributable to increased demand and higher pricing for shipping and logistics services in an improving economic environment. Our revenues during the six-month period ended June 30, 2020 were negatively impacted by the COVID-19 pandemic which disrupted businesses and the economy. The year-over-year changes in consolidated revenues for the three and six months ended June 30, 2021 reflect an increase in our Asset-Based revenues of 41.9% and 23.9%, respectively, and an increase in revenues of our Asset-Light operations (representing the combined operations of our ArcBest and FleetNet segments) of 66.9% and 54.6%, respectively. The increased elimination of revenue amounts reported in the “Other and eliminations” line of consolidated revenues for the three and six months ended June 30, 2021, compared to the same period of 2020, includes the impact of increased intersegment business levels among our operating segments, reflecting continued integration of our logistics services.

​

Our Asset-Based revenue improvement reflects an increase in billed revenue per hundredweight, including fuel surcharges, of 15.4% and 12.4% for the three and six months ended June 30, 2021, compared to the same periods of 2020, with per-day increases in tonnage of 22.7% and 11.7%, respectively, and shipments of 13.5% and 7.8%, respectively, for the three and six months ended June 30, 2021, compared to the same prior-year periods. The increase in revenues of our Asset-Light operations for the three and six months ended June 30, 2021 primarily reflects increases in revenue per shipment of 32.9% and 29.5%, respectively, and shipments per day of 39.0% and 30.4%, respectively, for the ArcBest segment, compared to the same period of 2020. An increase in roadside and maintenance service event volumes and higher revenue per event for FleetNet also contributed to the year-over-year revenue improvement. On a combined basis, the Asset-Light operating segments generated approximately 34% and 35% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2021, respectively, and 30% for the same periods of 2020.

​

Consolidated operating income totaled $74.3 million and $106.5 million for the three and six months ended June 30, 2021, respectively, compared to $20.4 million and $28.2 million for the same periods of 2020. The $53.9 million and $78.3 million increase in consolidated operating income for the three and six months ended June 30, 2021, respectively, is primarily due to the results of our operating segments (further described within the Asset-Based Segment Results and the Asset-Light Results sections of MD&A). The year-over-year comparisons of consolidated operating income were also impacted by items described in the following paragraphs, including cost reduction actions taken in second quarter 2020, costs related to investments in innovative technology, a gain on the sale of a subsidiary, certain nonunion performance-based incentive plans, certain other nonunion fringe benefits, and, for the six-month period, gains on the sales of property and equipment.

​

The comparisons of our consolidated operating income for the three and six months ended June 30, 2021 to the same prior-year periods are impacted by numerous actions we implemented, primarily in the second quarter of 2020, in response to the COVID-19 pandemic in anticipation of lower business levels. In April 2020, we implemented cost reduction actions which included a 15% reduction in the salaries of officers and nonunion employees and similar compensation adjustments for hourly nonunion employees; a 15% reduction in fees paid to members and committee chairpersons of ArcBest’s Board of Directors; implementation of a hiring freeze; suspension of the employer match on our nonunion 401(k) plan; and reduction of advertising, training, travel, and other costs to better align with current business levels. These compensation reductions lowered consolidated operating expenses by approximately $15 million in second quarter 2020. We also made workforce reductions in our Asset-Based network to better align resources with business levels during second quarter 2020. We reversed our cost reductions beginning in the third quarter of 2020, including officer and nonunion employee salaries, the employer match on our nonunion 401(k) plan, and fees for our Board of Directors.

​

Innovative technology costs related to the freight handling pilot test program at ABF Freight impacted consolidated results by $7.4 million (pre-tax), or $5.6 million (after-tax) and $0.21 per diluted share, for second quarter 2021, compared to $4.7 million (pre-tax), or $3.6 million (after-tax) and $0.14 per diluted share, for second quarter 2020. For the six months ended June 30, 2021, these costs impacted consolidated results by $14.3 million (pre-tax), or $10.9 million (after-tax) and $0.40 per diluted share, compared to $9.3 million (pre-tax), or $7.2 million (after-tax) and $0.27 per diluted share, for the same period of 2020. The freight handling pilot test program is discussed in the Asset-Based Operating Income section of Asset-Based Segment Results within Asset-Based Operations.

​

Consolidated operating results for the three and six months ended June 30, 2021 also benefited from the sale of a portion of our ArcBest segment’s moving labor services business in second quarter 2021 which resulted in a gain of $6.9 million (pre-tax), or $5.4 million (after-tax) and $0.20 per diluted share.

​

For the three and six months ended June 30, 2021, compared to the same periods of 2020, expenses for certain nonunion performance-based incentive plans, including long-term incentive plans impacted by shareholder returns relative to peers, increased $14.0 million and $22.5 million, respectively. Nonunion healthcare expenses increased $3.4 million and $4.5 million for the three and six months ended June 30, 2020, respectively, versus the same prior-year periods. For the six months ended June 30, 2021, consolidated operating income also benefited from gains on the sale of property and equipment, which increased $5.3 million compared to the same period of 2020.

​

The loss reported in the “Other and eliminations” line, which totaled $5.9 million and $13.0 million for the three and six months ended June 30, 2021, respectively, compared to $2.7 million and $7.7 million for the same periods of 2020, includes expenses related to investments to develop and design various ArcBest technology and innovations as well as expenses related to shared services for the delivery of comprehensive transportation and logistics services to ArcBest’s customers. The $3.2 million and $5.3 million increase in the loss reported in “Other and eliminations” for the three and six months ended June 30, 2021, respectively, primarily reflects higher expenses compared to the same periods of 2020, due to the previously discussed cost reductions during the second quarter of 2020 in response to the COVID-19 pandemic and increases in shared service personnel expenses related to higher business levels in the 2021 periods compared to the weaker economic environment experienced in the prior-year periods. We expect the loss reported in “Other and eliminations” for third quarter and full-year 2021 to approximate $5 million and $24 million, respectively.

​

In addition to the above items, consolidated net income and earnings per share were impacted by changes in the cash surrender value of variable life insurance policies, tax benefits from the vesting of share-based compensation awards, 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 net income by $1.2 million, or $0.05 per diluted share, and $2.5 million, or $0.09 per diluted share, for the three and six months ended June 30, 2021, respectively, compared to an increase in net income of $2.6 million, or $0.10 per diluted share, and a decrease of $1.2 million, or $0.05 per diluted share, respectively, for the same prior-year periods. The vesting of restricted stock units, which primarily occurs in the second quarter of each year, resulted in a tax benefit of $6.8 million, or $0.25 per diluted share, and $6.9 million, or $0.26 per diluted share, for the three and six months ended June 30, 2021, respectively, compared to tax expense of $0.7 million, or $0.03 per diluted share, for each of the same periods of 2020.

​

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

We report our financial results in accordance with 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 businesses, 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 Third Amended and Restated Credit Agreement (see Note F 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.

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 (“ABF Freight”). 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 2020 Annual Report on Form 10-K. 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 2020 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.

​

Pounds per day or Tonnage per day (average daily shipment weight) – pounds or 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 weighted based on the size of shipments.

​

29

Table of Contents

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

​

Billed revenue per hundredweight, including fuel surcharges (yield) – revenue per every 100 pounds of shipment weight, including surcharges related to fuel, 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 the Company’s 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 transportation is used; however, the labor efficiency may be partially 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.

​

As of June 2021, approximately 82% of our Asset-Based segment’s employees were covered under the ABF National Master Freight Agreement (the “2018 ABF NMFA”), the collective bargaining agreement with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023. Under the 2018 ABF NMFA, the contractual wage and benefits costs, including the ratification bonuses and vacation restoration, are estimated to increase approximately 2.0% on a compounded annual basis through the end of the agreement. Profit-sharing bonuses based on the Asset-Based segment’s annual operating ratios for any full calendar year under the contract represent an additional increase in costs under the 2018 ABF NMFA. The contractual wage rate under the 2018 ABF NMFA increased

1.7% effective July 1, 2021, and the average health, welfare, and pension benefit contribution rate is expected to increase

approximately 2.5% effective primarily on August 1, 2021.

Asset-Based Revenues

Asset-Based segment revenues for the three and six months ended June 30, 2021 totaled $652.8 million and $1,209.1 million, respectively, compared to $460.1 million and $975.8 million, respectively, for the same periods of 2020. The increase in revenues for the three and six months ended June 30, 2021 reflects improvement in business levels compared to the significant reduction in demand experienced in second quarter 2020 as a result of the COVID-19 pandemic. Billed revenue (as described in the Asset-Based Segment Overview) increased 41.6% and 25.6% on a per-day basis for the three and six months ended June 30, 2021, respectively, compared to the same prior-year periods. For the three and six months ended June 30, 2021, the increase in billed revenue reflects a 22.7% and 11.7% increase in tonnage

per day, respectively, and a 15.4% and 12.4% increase in total billed revenue per hundredweight, including fuel surcharges, respectively, compared to the same periods of 2020. The number of workdays was the same in second quarter 2021 and fewer by one day in the first half of 2021, versus the same periods of 2020.

​

Tonnage per day increased 22.7% and 11.7% for the three and six months ended June 30, 2021, respectively, compared to the same prior-year periods, due to increases in weight per shipment on higher daily shipment levels. The year-over-year increase in tonnage per day for the three months ended June 30, 2021 reflects double-digit percentage increases in both LTL-rated and truckload-rated tonnage per day. For the six months ended June 30, 2021, tonnage growth reflects a double-digit percentage increase in LTL-rated tonnage per day, partially offset by a low-single-digit percentage decrease in truckload-rated spot shipment tonnage moving in the Asset-Based network. Total shipments increased 13.5% and 7.8% on a per-day basis for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, primarily driven by increases in LTL-rated shipments reflecting strong customer demand. Larger-sized LTL-rated shipments, including an increase in pieces per shipment, impacted the growth in total weight per shipment for the three and six months ended June 30, 2021. Truckload-rated tonnage was positively impacted by strong demand for U-Pack household goods moving services in the three- and six-month periods ended June 30, 2021. The total truckload-rated tonnage metrics for the three and six month periods compared to the same prior-year periods were impacted by reductions in spot-quoted shipments.

​

The 15.4% and 12.4% increase in total billed revenue per hundredweight, including fuel surcharges, for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, was primarily due to a strong pricing environment and changes in freight profile and business mix to optimize revenue on shipments in the Asset-Based network. A higher mix of LTL-rated shipments and an increase in U-Pack business, as well as a longer average length of haul and higher fuel surcharge revenues associated with increased fuel prices, positively impacted the total billed revenue per hundredweight measure for the three and six months ended June 30, 2021, compared to the same prior-year periods. On-going yield management initiatives, including a general rate increase, also contributed to the year-over-year improvement in billed revenue per hundredweight. Excluding the impact of fuel surcharges, the increase in billed revenue per hundredweight on LTL-rated freight was in the mid-single digits for the three and six months ended June 30, 2021, respectively, compared to the same prior-year periods. Prices on accounts subject to deferred pricing agreements and annually negotiated contracts which were renewed during the three and six months ended June 30, 2021 increased approximately 6.7% and 6.1%, respectively, compared to the same periods of 2020. Pricing on contractual business reflected higher than historical average increases primarily due to tight market capacity and increased customer business levels. The Asset-Based segment implemented nominal general rate increases on its LTL base rate tariffs of 5.95% and 5.9% effective January 25, 2021 and February 24, 2020, respectively, although the rate changes vary by lane and shipment characteristics.

​

The Asset-Based segment’s average nominal fuel surcharge rate for the three and six months ended June 30, 2021 increased approximately 440 and 220 basis points, respectively, compared to the same periods of 2020. 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 the related fuel surcharges.

​

Asset-Based Operating Income

The Asset-Based segment generated operating income of $63.9 million and $94.0 million for the three and six months ended June 30, 2021, respectively, compared to $21.0 million and $34.3 million for the same periods of 2020. The Asset-Based segment’s operating ratio improved by 5.2 and 4.3 percentage points for the three and six months ended June 30, 2021, respectively, compared to the same prior-year periods, reflecting the increased revenues and management of operating resources to higher shipment levels. Operating income for the six months ended June 30, 2021 was also positively impacted by the sale of an unutilized property which contributed to the $8.6 million of total gains on the sale of property and equipment, compared to $3.3 million in the same prior-year period.

​

Innovative technology costs related to the freight handling pilot test program at ABF Freight impacted operating results of the Asset-Based segment by $7.5 million and $14.4 million for the three and six months ended June 30, 2021, respectively, compared to $4.8 million and $9.3 million, respectively, for the same periods of 2020. The pilot, which began in early 2019, is in the early stages in a limited number of locations. While ArcBest believes the pilot has potential to provide safer and improved freight handling, a number of factors will be involved in determining proof of concept and there can be no assurances that pilot testing will be successful or expand beyond current testing locations. We anticipate innovative technology costs associated with the pilot to impact our Asset-Based operating expenses by approximately $7.5 million in third quarter 2021, compared to $6.2 million in third quarter 2020.

​

The segment’s operating ratio was also impacted by changes in operating expenses as discussed in the following paragraphs.

​

Asset-Based Operating Expenses

Labor costs, which are reported in operating expenses as salaries, wages, and benefits, amounted to 46.3% and 48.6% of Asset-Based segment revenues for the three and six-month period ended June 30, 2021, respectively, compared to 54.1% 54.6%, respectively, for the same periods of 2020. The decreases in salaries, wages, and benefits as a percentage of revenue for the three and six months ended June 30, 2021, compared to the same prior-year periods, were partially offset by higher utilization of purchased transportation to meet customer demand for increased shipment levels. The improvement in salaries, wages, and benefits as a percentage of revenue was also influenced by the effect of higher revenues including fuel surcharges, as a portion of operating costs are fixed in nature and decrease as a percent of revenue with increases in revenue levels. Salaries, wages, and benefits increased $53.4 million and $55.2 million for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, primarily due to the increase in business levels. The increase in expense also reflects higher expense accruals for certain performance-based incentive plans, year-over-year increases in contractual wage and benefit contribution rates under the 2018 ABF NMFA, and higher nonunion wages and benefits versus the prior-year periods when cost reductions were in place in response to the COVID-19 pandemic, as previously discussed in the Consolidated Results section of MD&A. The contractual wage rate under the 2018 ABF NMFA increased 1.6% effective July 1, 2020, and the average health, welfare, and pension benefit contribution rate increased approximately 2.2% effective primarily on August 1, 2020.

​

The Asset-Based segment manages costs with shipment levels; however, increased shipment levels, freight profile changes, challenges with hiring an adequate number of personnel, and equipment capacity constraints pressured the efficiency of dock, street, and yard tasks during the second quarter of 2021. Shipments per DSY hour declined 2.8% for the second quarter of 2021, compared to second quarter 2020, primarily due to inefficiencies driven by equipment capacity constraints related to the business growth and the effect of handling a higher number of larger LTL-rated shipments, including an increase in pieces per shipment. For the six months ended June 30, 2021, shipments per DSY hour improved 0.4% compared to the same period of 2020. While the Asset-Based segment has added employees to service the business growth, the segment had to supplement resources with increased utilization of higher-cost purchased transportation in certain locations to manage service levels. The decrease in pounds per mile of 5.4% and 4.4% for the three and six months ended June 30, 2021, respectively, compared to the same period of 2020, was due to the higher number of miles (including purchased transportation miles) incurred to service the business growth and the increase in average length of haul resulting from intended changes in business mix, which was compensated by an increase in billed revenue per shipment.

​

Fuel, supplies, and expenses as a percentage of revenue for the second quarter of 2021 was consistent with the second quarter of 2020. For the six months ended June 30, 2021, fuel, supplies, and expenses as a percentage of revenue decreased 0.6 percentage points, compared to the same period of 2020. The changes in fuel, supplies, and expenses as a percentage of revenue were influenced by the effect of higher revenues including fuel surcharges, as a portion of operating costs are fixed in nature and decrease as a percent of revenue with increases in revenue levels. Fuel, supplies, and expenses increased $19.0 million and $18.6 million for the three and six months ended June 30, 2021, respectively, compared to the same prior-year period, primarily due to higher fuel costs as the Asset-Based segment’s average fuel price per gallon (excluding taxes) increased approximately 96% and 39% during the three and six months ended June 30, 2021, respectively, compared to the same period of 2020. More miles driven as a result of the increase in business levels also contributed to the year-over-year increases in fuel, supplies, and expenses. For the six months ended June 30, 2021, fuel, supplies, and expenses was also impacted by higher expenses associated with increased business levels and weather-related service center

expenses resulting from severe winter storms in first quarter 2021, partially offset by lower costs related to repairs and maintenance on tractors and trailers.

​

Depreciation and amortization as a percentage of revenue decreased 1.5 and 0.9 percentage points for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020; however, depreciation and amortization expense was relatively consistent across the periods. The decrease in depreciation and amortization as a percentage of revenue was influenced by the effect of higher revenues, as a portion of operating costs are fixed in nature and decrease as a percent of revenue with increases in revenue levels.

​

Rents and purchased transportation as a percentage of revenue increased 4.6 and 3.7 percentage points for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, primarily due to higher utilization of rail, local delivery agents, and linehaul purchased transportation necessary to serve the needs of our customers as freight demand increased across the Asset-Based system during the first half of 2021. For the three- and six-month periods ended June 30, 2021, rail miles increased approximately 53% and 39%, respectively, compared to the same prior-year periods.

​

Shared services as a percentage of revenue increased 0.7 percentage points for each of the three- and six-month periods ended June 30, 2021, compared to the same periods of 2020, primarily due to the cost reductions that were in place during 2020 in response to the COVID-19 pandemic, as previously discussed in the Consolidated Results section of MD&A. In addition, the increase in costs as a percentage of revenue reflects higher expense accruals for certain performance-based incentive plans, including long-term incentive plans impacted by shareholder returns relative to peers, for which the timing of recognition was impacted by the effect of the COVID-19 pandemic on operating results for the first half of 2020. The business growth also resulted in higher shared service expense allocations for the three and six months ended June 30, 2021, compared to same prior-year periods.

​

Asset-Based Segment — July 2021

The year-over-year improvements in our Asset-Based business levels during the first half of 2021 continued during July 2021 as the segment benefited from a strong pricing environment and increased customer business levels. Although statistics for July 2021 have not been finalized, preliminary Asset-Based billed revenues increased approximately 25% on a per-day basis in July 2021, compared to July 2020, reflecting an increase in average daily total tonnage of approximately 5% and an increase in total billed revenue per hundredweight, including fuel surcharges, of approximately 20%. Total shipments per day increased approximately 3% in July 2021, compared to July 2020. Total weight per shipment increased approximately 2% in July 2021, with the weight per shipment on LTL-rated shipments up approximately 6%, versus the same prior-year period.

​

The first quarter of each year generally has the highest operating ratio of the year, although other factors, including the current economic recovery, may influence quarterly comparisons. Current economic conditions and the Asset-Based segment’s pricing approach (which is described in the Asset-Based Segment Overview within the Results of Operations section of Item 7 (MD&A) of Part II of our 2020 Annual Report on Form 10-K) will continue to impact our Asset-Based segment’s tonnage levels and the prices it receives for its services and, as such, there can be no assurance that our Asset-Based segment will maintain or achieve improvements in its current operating results. Our efforts to manage operational costs in the Asset-Based network may not directly correspond to significant changes in business levels and there can be no assurance that the impact of the COVID-19 pandemic will not have an adverse effect on our operating results in future periods. The marketplace pricing environment has been positive and rational during our efforts to secure needed price increases; however, the competitive environment could limit the Asset-Based segment from securing adequate increases in base LTL freight rates and could limit the amount of fuel surcharge revenue recovered in future periods.

Asset-Light Operations

​

Asset-Light Overview

​

The ArcBest and FleetNet reportable segments, combined, represent our Asset-Light operations. Our Asset-Light operations are a key component of our strategy to offer customers a single source of integrated logistics solutions, designed to satisfy the complex supply chain and unique shipping requirements customers encounter.

34

Table of Contents

​

Our Asset-Light 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 2020 Annual Report on Form 10-K. The key indicators necessary to understand our Asset-Light operating results 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 segments. 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 operations:

​

| ● | Customer demand for logistics and premium transportation services combined with economic factors which influence the number of shipments or service events 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, for the ArcBest segment.

​

Service events – roadside, preventative maintenance, or total service events during the period, compared to the same prior-year period, for the FleetNet segment.

​

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

​

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

​

| ● | Availability of market capacity and cost of purchased transportation to fulfill customer shipments of the ArcBest segment, 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 ArcBest segment exclude statistical data of the managed transportation solutions transactions. Growth in managed transportation solutions has increased the number of shipments for these services to approximately one half of the ArcBest segment’s total shipments, while the business represents less than 20% of segment revenues for the three and six months ended June 30, 2021. 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 ArcBest 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, operating cash flow, net income, or earnings per share, as determined under GAAP.

Asset-Light Results

​

For the three and six months ended June 30, 2021, the combined revenues of our Asset-Light operations totaled $330.3 million and $641.8 million, respectively, compared to $197.9 million and $415.1 million, respectively, for the same periods of 2020. The increase in revenues for the three and six months ended June 30, 2021 reflects improvement in business levels compared to the significant reduction in demand experienced in second quarter 2020 as a result of the COVID-19 pandemic. The combined revenues of our Asset-Light operating segments generated approximately 34% and 35% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2021, respectively, compared to approximately 30% for both the three and six months ended June 30, 2020. Our Asset-Light combined operating income for the three and six months ended June 30, 2021 improved to $16.3 million and $25.6 million, respectively, compared to $2.1 million and $1.7 million, respectively, for the same prior-year periods, primarily reflecting improved demand and higher market prices resulting from tighter truckload market capacity. The year-over-year operating income improvement also benefited from a $6.9 million gain on the sale of the labor services subsidiary within the segment’s moving business during the second quarter of 2021.

​

ArcBest segment revenues totaled $270.7 million and $523.1 million for the three and six months ended June 30, 2021, respectively, compared to $151.5 million and $316.2 million, respectively, for the same periods of 2020. The 78.8% and 65.4% respective increases in revenues primarily reflect improved market demand compared to the same periods of 2020, which were negatively impacted by the COVID-19 pandemic. The revenue increases for the three and six months ended June 30, 2021, compared to the same periods of 2020, primarily reflect increases in revenue per shipment of 32.9% and 29.5%, respectively, associated with higher market prices resulting from tighter truckload capacity and increases in shipments per day (excluding managed transportation shipments) of 39.0% and 30.4%, respectively, due to strong customer

demand. Customers’ growing need for comprehensive, managed logistics solutions and new account growth also contributed to the year-over-year increases in revenues.

Operating income totaled $15.1 million and $23.4 million for the three and six months ended June 30, 2021, respectively, compared to operating income of $1.3 million and an operating loss of $0.1 million for the same periods of 2020, respectively, with the improvement primarily reflecting the increases in revenues. Increased customer shipping levels combined with limited equipment availability in the logistics marketplace positively impacted demand and pricing for ground expedite services for the three and six months ended June 30, 2021 and contributed to the segment’s operating income improvement, compared to the prior-year periods. Operating results for the three and six months ended June 30, 2021 also benefited from a $6.9 million gain on the sale of a subsidiary within the segment’s moving business, as previously mentioned, which contributed 2.6 and 1.3 percentage points to the segment’s operating ratio for the three and six months ended June 30, 2021, respectively.

​

The segment’s purchased transportation costs as a percentage of revenue increased by 1.1 and 0.7 percentage points for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020. Due to changes in market conditions and freight mix, the prices paid for purchased transportation increased by a higher percentage than the prices we secured from customers, resulting in margin compression during the three and six months ended June 30, 2021, compared to the same periods of 2020. Significant changes in market capacity, such as those experienced during 2020 and 2021, impact the cost of sourcing such capacity which may not correspond to the timing of revisions to customer pricing and our revenue per shipment.

​

As previously discussed in the Consolidated Results section of MD&A, prior-year operating expenses were lower due to corporate cost reductions in place during the second quarter of 2020, in response to the COVID-19 pandemic. As cost reductions were lifted, operating expenses returned to more normal levels, resulting in increases when comparing to prior-year periods. Operating results for the three and six months ended June 30, 2021 were also impacted by higher operating expenses due to increased business levels and growth initiatives, including investments in technology and increased wages and costs to manage higher shipment volumes. These higher expenses contributed to the $10.2 million and $14.6 million increase in shared service costs for the three and six months ended June 30, 2021, respectively, compared to the same prior-year periods. Shared service costs as a percentage of revenue decreased 1.7 and 2.3 percentage points for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, due to the effect of higher revenues, as a portion of these costs are fixed in nature and decrease as a percentage of revenue with increases in revenue levels. Although the ArcBest segment manages costs with shipment levels, portions of operating expenses are fixed in nature and cost reductions can be limited as the segment strives to enhance capacity sources and maintain customer service.

​

ArcBest Segment –July 2021

The year-over-year improvements in our ArcBest segment business levels during the first half of 2021 continued during July 2021. Although statistics for July 2021 have not been finalized, preliminary revenues of our ArcBest segment on a per-day basis in July 2021 were approximately 47% above the prior-year period, reflecting increases in shipments per day and revenue per shipment, as the segment benefited from continued customer demand in an improving economic environment and higher market prices resulting from tighter truckload market capacity. Current economic conditions will continue to impact business levels and purchased transportation costs of our ArcBest segment and, as such, there can be no assurance that the effect of the economic environment, including the impact of the COVID-19 pandemic, will not have an adverse effect on the operating results of our ArcBest segment in future periods.

​

FleetNet Segment

FleetNet’s revenues totaled $59.5 million and $118.7 million for the three and six months ended June 30, 2021, respectively, compared to $46.4 million and $98.9 million, respectively, for the same periods of 2020. The 28.2% and 20.1% increases in revenues for the three and six months ended June 30, 2021, respectively, compared to the same periods of 2020, were driven by higher event volumes and increases in revenue per event for roadside and preventative maintenance services. FleetNet’s results reflect higher demand for its services compared to the same periods of 2020, which were impacted by a reduction in miles driven by customers as a result of the COVID-19 pandemic. The increase in roadside service event volumes was also impacted by a higher number of events from customers who experienced an increase in e-commerce business and, for the six-month period, severe winter weather during the first quarter of 2021.

​

FleetNet’s operating income totaled $1.1 million and $2.2 million for the three and six months ended June 30, 2021, respectively, compared to $0.8 million and $1.8 million, respectively, for the same periods of 2020, primarily reflecting the increases in revenues. FleetNet’s operating income margins for the second quarter of 2021 benefited from increases in revenue per event which outpaced the increased costs to service events. For the six months ended June 30, 2021, the impact of higher revenue per event on FleetNet’s operating income margins was offset by the effect of higher costs to service the increase in total events, compared to the same period of 2020.

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, 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. The measure is particularly meaningful for analysis of our Asset-Light businesses, because it excludes amortization of acquired intangibles and software, 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, operating cash flow, net income, or earnings per share, as determined under GAAP.

Current Economic Conditions

​

The COVID-19 pandemic negatively impacted the economy and challenged business operations and supply chains during 2020, which resulted in declines in our business levels and operating results primarily in the second quarter of 2020. Economic conditions continued to improve during the first half of 2021. During the first quarter of 2021, certain COVID-19 vaccines were approved by the U.S. Food and Drug Administration for emergency use and a roll-out process began to provide the vaccines to qualified individuals. Vaccinations and other health and safety measures implemented in response to the pandemic slowed the spread of COVID-19 in many geographical areas and lessened the severity of COVID-related restrictions throughout portions of the United States. However, the Delta variant, a highly contagious coronavirus strain which was first identified in India in December 2020, spread to the United States in March 2021 and is now the dominant variant of the virus. Cases have been rising in the United States since early July, especially in certain geographic regions. In late-July 2021, the Centers for Disease Control and Prevention updated their guidance to recommend fully vaccinated people (along with unvaccinated people) should wear masks indoors in public in areas of substantial or high transmission of COVID-19. The recent surge in the Delta variant has increased the uncertainty of the future impact of the COVID-19 pandemic on the economy and business operations.

​

We are encouraged by the growth in the U.S. real gross domestic product (the “real GDP”) since the second quarter of 2020, when the National Bureau of Economic Research declared that a recession began in the United States in February 2020, and the improvements in other recent economic measures, including the Institute for Supply Management (ISM) Purchasing Managers’ Index (“PMI”) and the Industrial Production Index issued by the Federal Reserve. According to the advance estimate released by the Bureau of Economic Analysis on July 29, 2021, real GDP increased at an annual rate of 6.5% for second quarter 2021. The Industrial Production Index, while still below pre-pandemic levels, increased at an annual rate of 5.5% for second quarter 2021. PMI, which is a leading indicator for demand in the freight transportation and logistics industry, was 59.5% for July 2021, compared to 53.7% for July 2020 and 41.5% in April 2020, which was the lowest monthly PMI during the pandemic. The improvement in PMI reflects continued economic expansion in the manufacturing sector and growth in the overall economy. Manufacturing and trade inventory levels remain well below the range we consider optimal for businesses which is considered a positive for freight demand; although there can be no assurance that the economic environment, including the impact of the COVID-19 pandemic, will be favorable for our freight services in future periods.

​

Given the uncertainties regarding the economic environment and the potential impact of the COVID-19 pandemic on our business in future periods, there can be no assurance that our estimates and assumptions 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. Significant declines in 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 non-cash write-off of a significant portion of the goodwill and intangible assets of our ArcBest segment, which would have an adverse effect on our financial condition and operating results.

​

Effects of Inflation

​

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. Generally, inflationary increases in labor, fuel costs, and other operating expenses 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.

​

Generally, inflationary increases in labor and operating costs regarding our Asset-Light operations 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.

​

Supply chain disruptions and component shortages due in part to closure of suppliers’ and manufacturers’ operations during the COVID-19 pandemic as well as strong demand in recent quarters have limited the availability and production of certain revenue equipment and certain other equipment used in our business operations. Consequently, 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 based on value provided to the customer. 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.

​

In addition to general effects of inflation, the motor carrier freight transportation industry faces rising costs related to insurance claims and coverage and 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. 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.

​

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. 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 legal matters in which we are currently involved.

​

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 ransomware attacks and other cybersecurity attacks and other cyber incidents that impact the availability, reliability, speed, accuracy, 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 may develop and implement may also be subject to cybersecurity attacks and may be more 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 systems, any of which may increase the risk of a 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 cyber attacks 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 information technology 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, computer viruses, and other events beyond our control. It is not practicable to 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; a fire suppression system to protect our on-site data center; 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. In response to the health and safety risks posed by the COVID-19 pandemic and in an effort to mitigate the spread of COVID-19, we transitioned a significant portion of our office personnel to remote work arrangements during 2020, and many of these employees are still working remotely, which may increase our exposure to cybersecurity risks, including an increased demand for information technology resources, an increased risk of phishing, and an increased risk 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.

​

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 would likely 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. A significant disruption in our information technology 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, 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 must continuously monitor and develop our information technology 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 cyber attacks. Management is not aware of any 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 operations, and borrowing capacity under our revolving credit facility or accounts receivable securitization program.

​

Cash Flow and Short-Term Investments

​

Components of cash and cash equivalents and short-term investments were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | June 30 | ​ | December 31 |
​ | 2021 |  | 2020 |
​ | (in thousands) |
Cash and cash equivalents(1) | $ | 362,619 | ​ | $ | 303,954 | ​
Short-term investments(2) |  | 59,967 | ​ |  | 65,408 | ​
Total(3) | $ | 422,586 | ​ | $ | 369,362 | ​

​

(1) | Cash equivalents consist of money market funds and variable rate demand notes.

(2) | Short-term investments consist of certificates of deposit and, at December 31, 2020, U.S. Treasury securities.

(3) | Cash, variable rate demand notes, and certificates of deposit are recorded at cost plus accrued interest, which approximates fair value. Money market funds are recorded at fair value based on quoted prices. U.S. Treasury securities are recorded at amortized cost plus accrued interest. A t June 30, 2021 and December 31, 2020, c ash, cash equivalents, and short-term investments totaling $132.5 million and $156.4 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

​

Cash, cash equivalents, and short-term investments increased $53.2 million from December 31, 2020 to June 30, 2021. During the six-month period ended June 30, 2021, cash on hand and cash provided by operations was used to repay $54.6 million of long-term debt (including $20.0 million repaid on the Credit Facility); fund $14.5 million of capital expenditures, net of proceeds from asset sales (and an additional $8.1 million of certain Asset-Based revenue equipment was financed with notes payable); fund $9.5 million of internally developed software; purchase $8.1 million of treasury stock; and pay dividends of $4.1 million on common stock.

​

The comparisons of our consolidated cash flows and liquidity for the six months ended June 30, 2021 to the same period of 2020 are impacted by actions we implemented during 2020 in response to the COVID-19 pandemic. In addition to the cost reductions previously discussed in the Consolidated Results section of MD&A, the following actions should be considered when analyzing our year-over-year cash flows and liquidity for the six months ended June 30, 2021. On March 26, 2020, we drew down the $180.0 million remaining available borrowing capacity under the initial maximum credit amount of our revolving credit facility (the “Credit Facility”) under our Third Amended and Restated Credit Agreement and borrowed $45.0 million under our accounts receivable securitization program. These borrowings were a proactive measure to increase our cash position and preserve financial flexibility in consideration of general economic and financial market uncertainty and the potential for cash flow disruption resulting from the COVID-19 outbreak. These funds supplemented our already strong cash and short-term investments position and were repaid during third quarter 2020. We also lowered our planned capital expenditures for 2020 by 30%, including a reduction in revenue equipment purchases of $18.0 million.

​

Cash provided by operating activities during the six months ended June 30, 2021 was $145.9 million compared to $82.1 million in the same prior-year period. Net income increased $66.6 million for the six months ended June 30, 2021, compared to the same period of 2020. The increase in net income includes a $6.9 million gain on the sale of the labor services subsidiary of the ArcBest segment’s moving business during second quarter 2021 and a $4.8 million increase in gains on the sale of property and equipment for the six months ended June 30, 2021, compared to the same period of 2020, primarily related to the sale of an unutilized property in the Asset-Based segment. Changes in operating assets and liabilities contributed $9.7 million to the increase in cash provided by operating activities during the six months ended June 30, 2021, compared to the same period of 2020. The increases in accounts payable and accrued expenses for the six months ended June 30, 2021 which were primarily due to the impact of higher business levels, compared to the decreases in these accounts for the same prior-year period, resulted in higher cash flows from operations. These cash flows were partially offset by the business-driven increase in accounts receivable for the six months ended June 30, 2021, versus a decrease in accounts receivable for the same period of 2020. Cash provided by operating activities also reflected federal

and state income tax payments, net of refunds, of $15.2 million for the six months ended June 30, 2021, compared to state and foreign income tax payments, net of refunds of federal and state income taxes, of $1.9 million for the six months ended June 30, 2020.

​

Financing Arrangements

​

In June 2021, we repaid $20.0 million of borrowings under our Credit Facility. We had available borrowing capacity of $199.4 million under the initial maximum credit amount of the Credit Facility, as of June 30, 2021.

​

We amended and restated our accounts receivable securitization program in June 2021. The amendment extended the maturity date of this program from October 1, 2021 to July 1, 2024, decreased the amount of available cash proceeds under the facility from $125.0 million to $50.0 million, and increased the amount of additional borrowings we may request under the accordion feature of the program from $25.0 million to $100.0 million, subject to certain conditions. As of June 30, 2021, our available borrowing capacity under the accounts receivable securitization program was $39.9 million, as reduced for standby letters of credit issued under the program.

​

Our financing arrangements are further discussed in Note F 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 operations, other equipment, facility improvements, software, certain service contracts, and other items for which amounts were not accrued in the consolidated balance sheet as of June 30, 2021. These purchase obligations totaled $138.3 million as of June 30, 2021, with $131.9 million estimated to be paid within the next year, $6.1 million estimated to be paid in the following two-year period, and $0.3 million to be paid within five years, provided that vendors complete their commitments to us. As of June 30, 2021, the amount of our purchase obligations has increased $93.7 million from December 31, 2020, primarily related to revenue equipment, real estate projects, and technology advancements which are included in our 2021 capital expenditure plan.

​

As of June 30, 2021, contractual obligations for operating lease liabilities, primarily related to our Asset-Based service centers, totaled $127.7 million, including imputed interest. The scheduled maturities of our operating lease liabilities as of June 30, 2021 are disclosed in Note E to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

Our contractual obligations related to our notes payable, which provide financing for revenue equipment and software purchases, totaled $196.3 million, including interest, as of June 30, 2021, for a decrease of $29.1 million from December 31, 2020. The scheduled maturities of our long-term debt obligations as of June 30, 2021 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 2020 Annual Report on Form 10-K during the six months ended June 30, 2021.

​

Our total capital expenditures for 2021, including amounts financed, are estimated to range from $160.0 million to $170.0 million, net of asset sales, reflecting a $10.0 million increase from our previously disclosed range related to planned real estate investments in the second half of 2021. Our estimated net capital expenditures for 2021 include revenue equipment purchases of $100.0 million, primarily for our Asset-Based operations. The remainder of 2021 expected capital expenditures include real estate projects, dock equipment upgrades and enhancements for our Asset-Based operations, and technology investments across the enterprise. We have the flexibility to adjust certain planned 2021 capital expenditures as business levels dictate. Depreciation and amortization expense, excluding amortization of intangibles, is estimated to be in the range of $115.0 million to $120.0 million in 2021. The amortization of intangible assets is estimated to be approximately $4.0 million in 2021. As we continue to make investments to provide assured capacity solutions to our customers, we expect to increase our revenue equipment purchases in 2022 by an estimated $50.0 million to $60.0 million from 2021 projected levels, and we preliminarily expect to increase our annualized capital expenditures above historical levels by an estimated $50.0 million to $75.0 million to upgrade and expand our Asset-Based service centers.

ABF Freight System, Inc. and certain other subsidiaries reported in our Asset-Based operating segment contribute to multiemployer health, welfare, and pension plans based generally on the time worked by their contractual employees, as specified in the collective bargaining agreement and other supporting supplemental agreements (see Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q).

​

Other Liquidity Information

​

General economic conditions, including the effects of the COVID-19 pandemic in future periods, along with competitive market factors 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 operations and maintain cash, cash equivalents, and short-term investments on hand as operating costs increase. Our 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 Credit Facility and our accounts receivable securitization program of $199.4 million and $39.9 million, respectively, at June 30, 2021. We believe these agreements provide borrowing capacity options necessary for growth of our businesses. We believe existing cash, cash equivalents, short-term investments, cash generated by operations, and amounts available under our Credit Facility or our accounts receivable securitization program will be sufficient to finance our operating expenses, fund our ongoing investments in technology, and repay amounts due under our financing arrangements. 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.

​

On July 27, 2021, our Board of Directors declared a dividend of $0.08 per share to stockholders of record as of August 11, 2021. We expect to continue to pay quarterly dividends on our common stock in the foreseeable future, although there can be no assurances 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.

​

We have a program in place to repurchase our common stock in the open market or in privately negotiated transactions. The program has no expiration date but may be terminated at any time at the Board of Directors’ discretion. Repurchases may be made using cash reserves or other available sources. During the six months ended June 30, 2021, we purchased 126,289 shares of our common stock for an aggregate cost of $8.1 million, leaving $41.9 million available for repurchase under the current buyback program.

​

Financial Instruments

​

We have not historically entered into financial instruments for trading purposes, nor have we historically engaged in a program for fuel price hedging. No such instruments were outstanding as of June 30, 2021. We have an interest rate swap agreement in place which is discussed in Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

​

Balance Sheet Changes

​

Accounts Receivable

Accounts receivable increased $39.6 million from December 31, 2020 to June 30, 2021, reflecting higher business levels in June 2021 compared to December 2020.

​

Accounts Payable

Accounts payable increased $33.2 million from December 31, 2020 to June 30, 2021, primarily due to increased business levels in June 2021 compared to December 2020.

​

Accrued Expenses

Accrued expenses increased $13.4 million from December 31, 2020 to June 30, 2021, primarily due to the timing effect on wage and vacation accruals at June 30, 2021, compared to December 31, 2020.

​

Table of Contents

Long-term Debt

The $46.5 million decrease in long-term debt, including current portion, from December 31, 2020 to June 30, 2021 is primarily due to the $20.0 million repayment of borrowings under our Credit Facility during second quarter 2021 and payments on note payables during the six months ended June 30, 2021.

​

Off-Balance Sheet Arrangements

​

At June 30, 2021, our off-balance sheet arrangements for purchase obligations totaled $138.3 million, as previously discussed in the Contractual Obligations section of Liquidity and Capital Resources.

​

We have no investments, loans, or any other known contractual arrangements with unconsolidated special-purpose entities, variable interest entities, or financial partnerships and have no outstanding loans with executive officers or directors.

​

​

Income Taxes

​

Our effective tax rate was 17.0% and 19.5% for the three and six months ended June 30, 2021, respectively, compared to 23.4% and 23.1%, respectively, for the same periods of 2020. 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, such as cash surrender value of life insurance and the settlement of share-based payment awards primarily vesting in the second quarter, may cause the full-year 2021 tax rate to vary significantly from the statutory rate.

​

Reconciliation between the effective income tax rate, as computed on income before income taxes, and the statutory federal income tax rate is presented in the following table:

​

(1) | The statute of limitations expired in the first quarter of 2020 for the federal tax refund for which the reserve for uncertain tax positions was established in 2018.

​

At June 30, 2021, we had $58.5 million of net deferred tax liabilities after valuation allowances. We evaluated the need for a valuation allowance for deferred tax assets at June 30, 2021 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 $1.4 million and $1.3 million at June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021, 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 revenue recognition, accelerated depreciation for tax purposes, and a significant number of liabilities such as vacation pay, workers’

compensation, and other liabilities, which, for tax purposes, are generally deductible only when paid. For the three months ended June 30, 2021 and 2020, income determined under income tax law exceeded financial reporting income.

​

During the six months ended June 30, 2021, we made federal and state tax payments of $15.3 million, and received refunds of less than $0.1 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.

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 2020 Annual Report on Form 10-K. There have been no updates to our critical accounting policies during the six months ended June 30, 2021. Management believes that there is no new accounting guidance issued but not yet effective that will impact our critical accounting policies.

ITEM 3. QUANTITATIVE AND QUALITATIV E DISCLOSURES ABOUT MARKET RISK

​

Risks associated with future economic impacts of the COVID-19 pandemic remain uncertain. Further discussion related to current economic conditions and the impact of the COVID-19 pandemic 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.

​

In June 2021, we repaid $20.0 million of borrowings under our Credit Facility. We had available borrowing capacity of $199.4 million under the initial maximum credit amount of the Credit Facility, as of June 30, 2021.

​

In June 2021, we amended and restated our accounts receivable securitization program to decrease the initial maximum credit amount of the program from $125.0 million to $50.0 million and to increase the additional borrowing we may request under an accordion feature of the program from $25.0 million to $100.0 million, subject to certain conditions. The maturity date of the accounts receivable securitization program was extended to July 1, 2024. As of June 30, 2021, we did not have any current principal borrowings under the accounts receivable securitization program and our available borrowing capacity, as reduced for standby letters of credit issued under the program, was $39.9 million.

​

Since December 31, 2020, there have been no other significant changes in the Company’s market risks as reported in the Company’s 2020 Annual Report on Form 10-K.

​

​

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. 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 June 30, 2021.

​

During the quarter ended June 30, 2021, the Company implemented a new human capital management (“HCM”) system which replaced the current payroll systems and certain components of the human resource systems. Certain processes and procedures were changed as a result of the HCM system implementation, which resulted in changes to the Company’s internal controls over financial reporting. The Company has implemented additional controls to mitigate internal control risks and performed testing to ensure data integrity. Other than these changes related to the HCM system implementation, no changes in the Company’s internal controls over financial reporting 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.
