Segment Reporting [Abstract]

Segment Reporting

NOTE 5. Segment Reporting

As we have continued to expand our service offerings and diversify our business, we have also made changes to the financial information that our CEO, who has been identified as our Chief Operating Decision Maker (CODM), uses to make operating and capital decisions. Beginning in the first quarter of 2023, we concluded that we have two reportable segments: Intermodal and Transportation Solutions (“ITS”) and Logistics which are based primarily on the services each segment provides. We have recast the prior period information to conform with the current year presentation. Our ITS segment includes our asset-light business lines: intermodal and dedicated trucking. Our Logistics segment includes our non-asset business lines: managed transportation, truck brokerage, final mile, consolidation, warehousing and fulfillment. We operate the following segments:

Intermodal and Transportation Solutions. Our Intermodal and Transportation Solutions segment offers high service, nationwide door-to-door intermodal transportation, providing value, visibility and reliability in both transcontinental and local lanes by combining rail transportation with local trucking. This segment includes our trucking operations which provides our customers with local pickup and delivery as well as high service local and regional trucking transportation using equipment dedicated to their needs. In 2023, approximately 78% of our drayage services was provided by our own fleet. We arrange for the movement of our customers’ freight in one of our approximately 50,000 containers. As of December 31, 2023, we operated trucking terminals at 26 locations throughout the United States, with locations in many large metropolitan areas. We also contract for services with independent owner-operators who supply their own equipment and operate under our regulatory authority. These assets and contractual services are used to support drayage for our intermodal service offering and to serve our customers who require high service local and regional trucking transportation using equipment dedicated to their needs. We contract with railroads to provide transportation for the long-haul portion of the shipment between rail terminals. Drayage between origin or destination and rail terminals are provided by our own trucking operations and third parties with whom we contract. Our dedicated service operation offers fleets of equipment and drivers to each customer on a contract basis, as well as the management and infrastructure to operate according to the customer’s high service expectations. As of December 31, 2023, our trucking transportation operation consisted of approximately 2,300 tractors, 2,900 employee drivers and 4,300 trailers. We also contract for services with approximately 460 independent owner-operators.

Logistics. Our Logistics segment offers a wide range of services including transportation management, freight brokerage services, shipment optimization, load consolidation, mode selection, carrier management, load planning and execution, warehousing, fulfillment, cross-docking, consolidation services and final mile delivery. Logistics includes our brokerage business which consists of a full range of trucking transportation services, including dry van, expedited, less-than-truckload (“LTL”), refrigerated and flatbed, all of which is provided by third-party carriers with whom we contract. We leverage proprietary technology along with collaborative relationships with third-party service providers to deliver cost savings and performance-enhancing supply chain services to our clients. Our transportation management offering also serves as a source of volume for our ITS segment. Many of the customers for these solutions are consumer goods companies who sell into the retail channel. Our final mile delivery offering provides residential final mile delivery and installation of appliances and big and bulky goods. Final mile operates through a network of independent service providers in company, customer and third-party facilities throughout the continental United States. Our business operates or has access to approximately 11 million square feet of warehousing and cross-dock space across North America, to which our customers ship their goods to be stored and distributed to destinations including residences, retail stores and other commercial locations. These services offer our customers shipment visibility, transportation cost savings, high service and compliance with retailers’ increasingly stringent supply chain requirements. Logistics also includes our brokerage business which provides third-party truckload, less-than-truckload (“LTL”), flatbed and temperature-controlled needs.

The following table summarizes our financial and operating data by segment (in thousands):

Accounting Policies [Abstract]

Description of Business and Summary of Significant Accounting Policies

NOTE 1. Description of Business and Summary of Significant Accounting Policies

Business: Hub Group, Inc. (“Hub”, “we”, “us” or “our”) is a leading supply chain solutions provider that offers comprehensive transportation and logistics management services focused on reliability, visibility and value for our customers. Our service offerings include a full range of freight transportation and logistics services, some of which are provided using assets we own and operate, and some of which are provided by third parties with whom we contract. Our transportation services include intermodal, truckload, less-than-truckload, flatbed, temperature-controlled, dedicated and regional trucking. Our logistics services include full outsource logistics solutions, transportation management services, freight consolidation, warehousing and fulfillment, final mile delivery, parcel and international services.

On December 20, 2023, we acquired Forward Air Final Mile (“FAFM”). On August 22, 2022, we acquired TAGG Logistics, LLC (“TAGG”). On October 19, 2021, we acquired Choptank Transport, LLC (“Choptank”). Refer to Note 4 “Acquisitions” for additional information.

Principles of Consolidation: The consolidated financial statements include our accounts and all entities in which we have more than a 50% equity ownership or otherwise exercise unilateral control. All significant intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents: We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2023 and 2022, our cash and temporary investments were with high quality financial institutions in demand deposit accounts (“DDAs”), savings accounts, checking accounts and money market accounts.

Accounts Receivable and Allowance for Uncollectible Accounts: The allowance for credit losses is a valuation account that is deducted from the trade receivables’ amortized cost basis to present the net amount expected to be collected on the receivables. Trade receivables are charged off against the allowance when we believe the uncollectibility of a receivable balance is confirmed, and the expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management continuously reviews and assesses the environment and its potential impact on the credit worthiness and collectability of our accounts receivable with customers most affected by tighter financial conditions. Our allowance for credit losses is presented in the allowance for uncollectible trade accounts and is immaterial at December 31, 2023 and 2022. The allowance for uncollectible trade accounts also includes estimated adjustments to revenue for items such as billing disputes. Our reserve for uncollectible accounts was approximately $34.7 million and $38.6 million as of December 31, 2023 and 2022, respectively. Receivables are written off once collection efforts have been exhausted. Recoveries of receivables previously charged off are recorded when received.

Property and Equipment: Property and equipment are stated at cost. Depreciation of property and equipment is computed using the straight-line method at rates adequate to depreciate the cost of the applicable assets over their expected useful lives: building and improvements, up to 40 years; leasehold improvements, the shorter of useful life or lease term; computer equipment and software, up to 10 years; furniture and equipment, up to 10 years; and transportation equipment up to 16 years. Direct costs related to internally developed software projects are capitalized and amortized over their expected useful life on a straight-line basis not to exceed 10 years. Interest is capitalized on qualifying assets under development for internal use. Maintenance and repairs are charged to operations as incurred and major improvements are capitalized. The cost of assets retired or otherwise disposed of and the accumulated depreciation thereon are removed from the accounts with any gain or loss realized upon sale or disposal charged or credited to operations. We review long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that the undiscounted future cash flows resulting from the use of the asset is less than the carrying amount, an impairment loss equal to the excess of the assets carrying amount over its fair value, less cost to dispose, is recorded.

Capitalized Internal Use Software and Cloud Computing Costs: We capitalize internal and external costs, which include costs related to the development of our cloud computing or hosting arrangements, incurred to develop internal use software per ASC Subtopic 350-40. Internal use software has both of the following characteristics: the software is acquired, internally developed, or modified solely to meet our needs and during the development or modification, no substantive plan exists or is being developed to market the software externally. Only costs incurred during the application development stage and costs to develop or obtain software that allows for access to or conversion of old data by new systems are capitalized. Capitalization of costs begins when the preliminary project stage is complete, management has committed to funding the project and it is probable the project will be completed, and the software will be used to perform its intended function. The measurement of the costs to capitalize include fees paid to third parties, costs incurred to obtain software from third parties, travel expenses incurred by employees in their duties associated with developing software, payroll related costs for employees who spend time directly on the project and interest costs incurred while developing internal-use software or implementing a hosting arrangement. Capitalization ceases no later than when the project is substantially complete and ready for its intended use, after all substantial testing is complete.

Goodwill and Other Intangibles: Goodwill represents the excess of purchase price over the fair market value of net assets acquired in connection with our business combinations. Goodwill and intangible assets that have indefinite useful lives are not amortized but are subject to annual impairment tests.

We test goodwill for impairment annually in the fourth quarter or when events or changes in circumstances indicate the carrying value of this asset might exceed the current fair value. We test goodwill for impairment at the reporting unit level. Beginning with the first quarter of 2023, we concluded that we had two reportable segments and two reporting units: Intermodal and Transportation Solutions (“ITS”) and Logistics which are based primarily on the services each segment provides. We assess qualitative factors such as current company performance and overall economic factors to determine if it is more-likely-than-not that the fair value of our reporting units is less than their carrying value and whether it is necessary to perform the quantitative goodwill impairment test. In the quantitative goodwill test, a company compares the carrying value of its reporting units to their fair value. If the fair value of a reporting unit is less than the carrying amount, then a goodwill impairment charge will be recognized in the amount by which carrying amount exceeds fair value, limited to the total amount of goodwill allocated to that reporting unit. We performed our annual assessment in the fourth quarter of 2023 and 2022 as required and determined it was not more-likely-than-not that the fair value of our reporting units was less than its carrying value.

We evaluate the potential impairment of finite-lived acquired intangible assets when impairment indicators exist. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Claims Accruals: We purchase insurance coverage for a portion of expenses related to employee injuries, vehicular collisions, accidents, and cargo damage. Certain insurance arrangements include high self-insurance retention limits or deductibles applicable to each claim. We have umbrella policies to limit our exposure to large claim costs.

Our claims accrual policy for all self-insured claims is to recognize a liability at the time of the incident based on our analysis of the nature and severity of the claims and analyses provided by third-party claims administrators, as well as legal and regulatory factors. Our safety and claims personnel work directly with representatives from the insurance companies to continually update the estimated cost of each claim. The ultimate cost of a claim develops over time as additional information regarding the nature, timing, and extent of damages claimed becomes available. Accordingly, we use an actuarial method to develop current claim information to derive an estimate of our ultimate claim liability. This process involves the use of loss-development factors based on our historical claims experience. In doing so, the recorded liability factors in future growth of claims and an allowance for incurred-but-not-reported claims. We do not discount our estimated losses. In addition, we record receivables for amounts expected to be reimbursed for payments made in excess of self-insurance levels on covered claims related to auto liability and workers’ compensation. At December 31, 2023 and 2022, we had an accrual of approximately $39.1 million and $38.8 million, respectively for estimated claims. We had no significant receivables recorded for payments in excess of our self-insured levels. Our claims accruals are classified in accrued other and non-current liabilities in the consolidated balance sheets, based on when the claim is estimated to be paid.

Concentration of Credit Risk: Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and temporary investments with high quality financial institutions in DDAs, savings accounts, checking accounts and money market accounts. We primarily serve customers located throughout the United States with no significant concentration in any one region. In each of the years ended December 31, 2023, 2022 and 2021, one customer accounted for more than 10% of our annual revenue in both segments. We review a customer’s credit history before extending credit. In addition, we routinely assess the financial strength of our customers and, as a consequence, believe that our trade accounts receivable risk is limited.

The following table includes the one customer that represented 10% or more of our annual revenue by segment during the last three fiscal years:


	Years Ended
Customer A	December 31,
	2023	2022	2021
ITS	13%	14%	14%
Logistics	11%	12%	15%
Total operating revenue	13%	13%	15%

Revenue Recognition: In accordance with the Accounting Standards Codification (ASC) topic 606, “Revenue from Contracts with Customers” our significant accounting policy for revenue is as follows:

Revenue is recognized when we transfer services to our customer in an amount that reflects the consideration we expect to receive. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We generally recognize revenue over time because of continuous transfer of control to the customer. Since control is transferred over time, revenue and related transportation costs are recognized based on relative transit time, which is based on the extent of progress towards completion of the related performance obligation. We enter into contracts that can include various combinations of services, which are capable of being distinct and accounted for as separate performance obligations. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Further, in most cases, we report our revenue on a gross basis because we are the primary obligor as we are responsible for providing the service desired by the customer. Our customers view us as responsible for fulfillment including the acceptability of the service. Service requirements may include, for example, on-time delivery, handling freight loss and damage claims, setting up appointments for pick-up and delivery and tracing shipments in transit. We have discretion in setting prices to our customers and as a result, the amount we earn varies. In addition, we have the discretion to select our vendors from multiple suppliers for the services ordered by our customers. These factors, discretion in setting prices and discretion in selecting vendors, further support reporting revenue on a gross basis for most of our revenue.

Provision for Income Taxes: Significant judgment is required in determining and assessing the impact of complex tax laws and certain tax-related contingencies on our provision for income taxes. As part of our calculation of the provision for income taxes, we assess whether the benefits of our tax positions are at least more likely than not to be sustained upon audit based on the technical merits of the tax position. For tax positions that are not more likely than not to be sustained upon audit, we accrue the largest amount of the benefit that is not more likely than not to be sustained in our financial statements. Such accruals require us to make estimates and judgments, whereby actual results could vary materially from these estimates. Further, years may elapse before a particular matter for which we have established an accrual is audited and resolved or its statute of limitations expires. We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes.

Deferred income taxes are recognized for the future tax effects of temporary differences between financial statement and income tax reporting using tax rates in effect for the years in which the differences are expected to reverse. We believe that it is more likely than not that our deferred tax assets will be realized based on future taxable income projections, with one exception. We have established a valuation allowance of $1.2 million related to federal and state tax credit carryforwards. In the event the probability of realizing the remaining deferred tax assets does not meet the more likely than not threshold in the future, a valuation allowance would be established for the deferred tax assets deemed unrecoverable.

Earnings Per Common Share: Basic earnings per common share are based on the average quarterly weighted average number of Class A and Class B shares of common stock outstanding. Diluted earnings per common share are adjusted for restricted stock using the treasury stock method.

Stock Based Compensation: Share-based compensation includes the restricted stock awards expected to vest based on the grant date fair value. Compensation expense is amortized straight-line over the vesting period and is included in salaries and benefits.

New Pronouncements: In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 enhanced annual disclosures regarding the rate reconciliation and income taxes paid information. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024. We are assessing the impact of this guidance on our disclosures; it will not have an impact on our results of operations, cash flows, or financial condition.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires retrospective disclosure of significant segment expenses and other segment items on an annual and interim basis. Additionally, it requires disclosure of the title and position of the Chief Operating Decision Maker (“CODM”). This ASU will be effective for the Company’s fiscal December 31, 2024 year-end and interim periods beginning in fiscal 2025, with early adoption permitted. We are assessing the impact of this guidance on our disclosures; it will not have an impact on our results of operations, cash flows or financial condition.

Use of Estimates: The preparation of financial statements in conformity with United States generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates include the allowance for uncollectible trade accounts, exposure for self-insured claims under our insurance policies, valuation of acquired goodwill and intangible assets and useful lives of assets. Actual results could differ from these estimates.

Reclassifications: Due to presentation changes made in our consolidated statements of income, certain prior year amounts have been reclassified to conform with the current year presentation.

On January 4, 2024, the Company announced a two-for-one stock split of the Company’s Class A and Class B common stock. The stock split was implemented in the form of a distribution of one additional Class A share for each share outstanding. The record date for the stock split was as of the close of business on January 16, 2024. The Company distribution date of the additional shares was January 26, 2024. As a result of the stock split, the number of authorized shares remained unchanged. Additionally, the par value per share of the common stock remains unchanged. All other share amounts in our consolidated balance sheets, consolidated statements of income and comprehensive income, consolidated statements of stockholders' equity and related footnote disclosures have been adjusted and presented as though the stock split had occurred on January 1, 2021.

NOTE 17. Related Party Transactions

In August 2022, the Company entered into a Common Stock Exchange and Repurchase Agreement (the “Agreement”) with entities affiliated with David P. Yeager, then the Company’s Chairman of the Board of Directors and Chief Executive Officer (collectively, the “DPY Entities”) and entities affiliated with Mark A. Yeager, the brother of David P.

Common Stock (the “Remaining Class B Shares”), representing all of the remaining shares of Class B Common Stock owned by the MAY Entities, for an aggregate purchase price of $34.8 million (the “Repurchase” and, together with the “Exchange,” the “Transaction”). The purchase price for the Repurchase was based on a price per share equal to the closing price of Class A Common Stock on the Nasdaq Global Market on the date of the Agreement. In accordance with the Company’s certificate of incorporation the Remaining Class B Shares acquired by the Company were cancelled and converted into Class A Common Stock upon acquisition and are not available for reissuance.

The Transaction was approved by the Company’s Audit Committee of the Board pursuant to the Company’s Related Person Transaction Policy approval procedures.

Long-Term Debt and Financing Arrangements

NOTE 10. Long-Term Debt and Financing Arrangements

In February 2022, we entered into a five-year, $350 million unsecured credit agreement (the "Credit Agreement"). Borrowings under the Credit Agreement generally bear interest at a variable rate equal to (i) the secured overnight financing rate (published by the Federal Reserve Bank of New York, “SOFR”), plus a specified margin based on the term of such borrowing, plus a specified margin based upon Hub’s total net leverage ratio (as defined in the Credit Agreement) (the "Total Net Leverage Ratio"), or (ii) the base rate (which is the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% and one-month SOFR) plus a specified margin based upon the Total Net Leverage Ratio. The specified margin for SOFR loans varies from 100.0 to 175.0 basis points per annum. The specified margin for base rate loans varies from 0.0 to 75.0 basis points per annum. Hub must also pay (1) a commitment fee ranging from 10.0 to 25.0 basis points per annum (based upon the Total Net Leverage Ratio) on the aggregate unused commitments and (2) a letter of credit fee ranging from 100.0 to 175.0 basis points per annum (based upon the Total Net Leverage Ratio) on the undrawn amount of letters of credit.

We have standby letters of credit that expire in 2024. As of December 31, 2023 and December 31, 2022, our letters of credit were $0.9 million and $43.4 million, respectively.

As of December 31, 2023 and December 31, 2022, we had no borrowings under our respective credit agreements and our unused and available borrowings were $349.1 million and $306.6 million, respectively.

We are subject to income taxation in the United States, numerous state jurisdictions, Mexico, Canada, and India. Because income tax return formats vary among the states, we file both unitary and separate company state income tax returns. We do not permanently reinvest our foreign earnings, all amounts are accrued and accounted for, though not material.

Our state tax net operating losses total $0.2 million. Some of those state losses have no expiration date while others will expire between December 31, 2024, and December 31, 2042. Management believes it is more likely than not that the loss carryforward deferred tax assets will be fully realized.

Our federal incentive tax credit carryforward of $0.1 million expires between December 31, 2025 and December 31, 2028. Our state incentive tax credit carryforwards of $8.1 million expire between December 31, 2024, and December 31, 2027. Management believes it is more likely than not that approximately $6.7 million of the incentive carryforward deferred tax assets will be realized and a valuation allowance of $1.2 million has been established for the remainder which are not expected to be realized.

As of December 31, 2023 and December 31, 2022, the amount of unrecognized tax benefits was $12.9 million and $11.1 million, respectively. If recognized, these benefits would decrease our income tax provision by $10.2 million and $9.0 million, respectively. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):


	2023			2022
Gross unrecognized tax benefits - beginning of the year	$	11,116		$	6,647
Gross increases related to prior year tax positions		761			425
Gross increases related to current year tax positions		1,460			4,665
Lapse of applicable statute of limitations		(478	)		(621	)
Gross unrecognized tax benefits - end of year	$	12,859		$	11,116

We recognize interest and penalties related to income tax liabilities in our provision for income taxes. In 2023, we included $0.1 million in our provision for income taxes.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic. Among other things, the CARES Act includes provisions related to refundable payroll tax credits, deferment of the employer portion of social security payments, net operating loss carryback periods, modifications to the net interest deduction limitations, and technical corrections to tax depreciation methods for qualified improvement property. On December 27, 2020, the Consolidated Appropriations Act (“CAA”) was enacted in further response to the COVID-19 pandemic, in combination with omnibus spending for the 2021 federal fiscal year. The CAA extended many of the provisions enacted by the CARES Act, Though some provisions of the CARES Act and CAA do impact the Company, there was no material effect on the Company’s consolidated financial condition or results of operations for the years ended December 31, 2023, 2022 or 2021.

The Inflation Reduction Act of 2022 was signed into law on August 16, 2022, and the CHIPS and Science Act of 2022 was signed into law on August 9, 2022. These laws implement new tax provisions, primarily a 15% corporate alternative minimum tax and a nondeductible 1% excise tax on the fair market value of stock repurchased by publicly traded corporations. We do not anticipate any other material impact of these provisions. The two acts also provide various tax credits, several of which are transferable or refundable, for the investment in or production of clean-energy effective January 1, 2023. We will continue to evaluate potential tax benefits available under the acts as additional guidance is issued in future periods.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

NOTE 11. Leases

In accordance with ASC 842, “Leases,” (“ASC 842”) which requires lessees to recognize a right-of-use asset (“ROU”) and a lease obligation for all leases, we made an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less.

As of December 31, 2023, we recorded $213.3 million of ROU assets and $224.8 million of lease liabilities on our consolidated balance sheet. As of December 31, 2022, we recorded $103.3 million of ROU assets and $109.3 million of lease liabilities on our consolidated balance sheet. The increase in ROU assets and lease liabilities was primarily the result of the TAGG acquisition. The lease liabilities recognized are measured based upon the present value of minimum future payments. The ROU assets are equal to lease liabilities upon initial recording, adjusted for prepaid and accrued rent balances which are recorded in the Consolidated Balance Sheets.

Hub currently does not have any variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate). Some leases have options to extend or terminate the agreement, which management assesses in determining the estimated lease term. If any of the options to extend a lease are exercised, this change will be reflected as a remeasurement of the ROU asset and lease liability accordingly. As of December 31, 2023, the ROU asset and lease liabilities do not reflect any options to extend or terminate a lease as management is not reasonably certain it will exercise any of these options. Also, current leases do not contain any restrictions or covenants imposed by the leases or residual value guarantees.

As of December 31, 2023, Hub signed new property lease contracts which had not commenced. Based on the present value of the lease payments, the estimated ROU assets and lease liabilities related to these contracts will total approximately $7.1 million.

Discount rates are not specified on the individual lease contracts at the commencement date. To determine the present value of the lease payments, Hub used its incremental borrowing rate which was determined based on Hub’s credit standing and factoring in the current 12-month SOFR rate published at the time of the lease commencement. This incremental borrowing rate represents the rate of interest that Hub would have to pay to borrow on a collateralized basis over a similar term and amounts equal to the lease payments in a similar economic environment. As of December 31, 2023, we are in the process of evaluating the leases for the FAFM acquisition.

Fair Value Disclosures [Abstract]

Fair Value Measurement

NOTE 8. Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable and accounts payable materially approximated fair value as of December 31, 2023 and 2022. As of December 31, 2023, the fair value of the Company’s fixed-rate borrowings was $1.4 million less than the historical carrying value of $350.7 million. As of December 31, 2022, the $342.5 million carrying value of the Company's fixed-rate borrowings approximated the fair value. The fair value of the fixed-rate borrowings was estimated using an income approach based on current interest rates available to the Company for borrowings on similar terms and maturities.

We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2023 and 2022, our cash and temporary investments were with high quality financial institutions in demand deposit accounts, savings accounts, checking accounts and money market accounts.

Restricted investments included $20.8 million and $18.1 million as of December 31, 2023 and 2022, respectively, of mutual funds and other security investments which are reported at fair value. These investments relate to the nonqualified deferred compensation plan that is described in Note 14 and insurance deposits.

Our assets and liabilities measured at fair value are based on valuation techniques which consider prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. These valuation methods are based on either quoted market prices (Level 1) or inputs, other than quoted prices in active markets, that are observable either directly or indirectly (Level 2), or unobservable inputs (Level 3). Cash and cash equivalents, accounts receivable, accounts payable and mutual funds and related liabilities are defined as “Level 1,” while long-term debt is defined as “Level 2” of the fair value hierarchy in the Fair Value Measurements and Disclosures Topic of the Codification.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

NOTE 6. Goodwill and Other Intangible Assets

Due to the change in segments in the first quarter of 2023, consolidated goodwill was reallocated to the two new reporting units based on their relative fair values. The Company performed an evaluation before and after the change and concluded it was not more-likely-than-not that the fair value of our reporting units was less than its carrying value. There were no accumulated impairment losses of goodwill at the beginning of the period.

The following table presents the carrying amount of Goodwill by segment (in thousands):


	ITS		Logistics		Consolidated
Balance at December 31, 2021	$	371,641	$	205,272	$	576,913
Acquisitions		-		52,489		52,489
Balance at December 31, 2022	$	371,641	$	257,761	$	629,402
Acquisitions		-		104,293		104,293
Balance at December 31, 2023	$	371,641	$	362,054	$	733,695

The components of the "Other intangible assets” are as follows (in thousands):


					Net
	Gross		Accumulated		Carrying
As of December 31, 2023:	Amount		Amortization		Value		Life
Customer relationships	$	376,956	$	92,827	$	284,129	5-15 years

Carrier network and agent relationships		15,000		8,563		6,437	4 years

Developed technology		17,223		3,247		13,976	4-7 years

Trade name		6,200		6,135		65	18 months
Consolidated Total	$	415,379	$	110,772	$	304,607


					Net
	Gross		Accumulated		Carrying
As of December 31, 2022:	Amount		Amortization		Value		Life
Customer relationships	$	249,223	$	72,157	$	177,066	5-15 years

Carrier network and agent relationships		15,000		4,813		10,187	4 years

Developed technology		10,500		1,449		9,051	4-7 years

Trade name		6,200		5,118		1,082	18 months
Consolidated Total	$	280,923	$	83,537	$	197,386

The above intangible assets are amortized using the straight-line method. Amortization expense was $27.2 million and $26.6 million for the years ended December 31, 2023 and 2022, respectively. The remaining weighted average life of all definite lived intangible assets was 11.32 years and 9.57 years for the years ended December 31, 2023 and 2022, respectively. Amortization expense for the next five years is expected to be as follows (in thousands):


	Total
Year 1	$	34,448
Year 2		33,345
Year 3		30,645
Year 4		30,287
Year 5		27,385

Retirement Benefits [Abstract]

Employee Benefit Plans

NOTE 14. Employee Benefit Plans

We have a profit-sharing plan under section 401(k) of the Internal Revenue Code. At our discretion, we partially match qualified contributions made by employees to the plan. We incurred expense related to the employer match for this plan of $8.5 million in 2023, $6.7 million in 2022 and $5.7 million in 2021.

In January 2005, we established the Hub Group, Inc. Nonqualified Deferred Compensation Plan (the “Plan”) to provide added incentive for the retention of certain key employees. Under the Plan, which was amended in 2008, participants can elect to defer certain compensation. Accounts grow on a tax-deferred basis to the participant. Restricted investments included in the Consolidated Balance Sheets represent the fair value of the mutual funds and other security investments related to the Plan as of December 31, 2023 and 2022. Both realized and unrealized gains and losses are included in income and expense and offset the change in the deferred compensation liability. We provide a 50% match on the first 6% of employee compensation deferred under the Plan which vests over three years with a maximum match equivalent to 3% of base salary. We incurred expense of $0.3 million per year related to the employer match for this plan in 2023, 2022 and 2021. The liability related to the Plan as of December 31, 2023 and 2022 were $20.5 million and $17.8 million, respectively.

Stock Repurchase Plans

NOTE 16. Stock Repurchase Plans

In October 2022, the Board authorized the purchase of up to $200 million of our Class A Common Stock pursuant to a share repurchase program (the “2022 Program”). Under the 2022 Program, the shares may be repurchased in the open market or in privately negotiated transactions, from time to time subject to market and other conditions. The approved share repurchase program does not obligate us to repurchase any dollar amount or number of shares and the program may be modified, suspended or discontinued at any time. The 2022 Program was terminated in October 2023 in conjunction with the authorization of the 2023 Program (as defined below) and as a result, no shares were purchased under the 2022 Program in the fourth quarter of 2023.

In October 2023, the Board authorized the purchase of up to $250 million of our Class A Common Stock pursuant to a share repurchase program (the “2023 Program”), which replaces the 2022 Program. Under the 2023 Program, the shares may be repurchased in the open market or in privately negotiated transactions, from time to time subject to market and other conditions. The approved share repurchase program does not obligate us to repurchase any dollar amount or number of shares and the program may be modified, suspended or discontinued at any time.

We purchased 4,020,598 shares for $153.9 million during 2023, 2,957,330 shares for $118.1 million during 2022 and 268,658 shares for $9.1 million in 2021. These amounts include the number of shares delivered to us by employees to satisfy the mandatory tax withholding requirement upon vesting of restricted stock, which do not reduce the repurchase authority under our share repurchase program.

Acquisitions

NOTE 4. Acquisitions

Forward Air Final Mile Acquisition

On December 20, 2023, we acquired 100% of the equity interest of Forward Air Final Mile (“FAFM”). FAFM provides residential last mile delivery services and installation of big and bulky goods, with a focus on appliances, throughout the United States. Total consideration for the transaction was $261 million paid from cash on hand. The financial results of FAFM, since the date of acquisition, are included in our Logistics segment.

The acquisition of FAFM expanded our final mile services to include the delivery and installation of appliances. FAFM provides residential last mile delivery services through a non-asset business model, working with a network of over 350 carriers throughout the country.

The initial accounting for the acquisition of FAFM is incomplete as we, with the support of our valuation specialist, are in the process of finalizing the fair market value calculations of the acquired net assets. In addition, the Company is in the preparation and final review process of the applicable future cash flows used in determining the purchase accounting. Finally, certain post-closing activities outlined in the acquisition agreement remain incomplete. As a result, the amounts recorded in the consolidated financial statements related to the FAFM acquisition are preliminary and the measurement period remains open. The following table summarizes the preliminary allocation of the total consideration to the assets acquired and liabilities assumed as of the date of the acquisition (in thousands):


	December 20, 2023
Accounts receivable trade	$	28,574
Prepaid expenses and other current assets		2,305
Property and equipment		3,241
Right-of-use assets - operating leases		15,003
Other intangibles		134,456
Goodwill		103,922
Other assets		173
Total assets acquired	$	287,674

Accounts payable trade	$	155
Accounts payable other		2,177
Accrued payroll		1,271
Accrued other		8,132
Lease liability - operating leases short-term		6,145
Other long term liabilities		19
Lease liability - operating leases long-term		8,857
Total liabilities assumed	$	26,756

Total consideration	$	260,918

Cash paid, net	$	260,918

The FAFM acquisition was accounted for as a purchase business combination in accordance with ASC 805 “Business Combinations.” Assets acquired and liabilities assumed were recorded in the accompanying consolidated balance sheet at their estimated fair values as of December 20, 2023 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the FAFM acquisition was primarily attributable to potential expansion and future development of the acquired business.

Tax history and attributes are not inherited in an equity purchase of this kind, however, the goodwill and other intangibles recognized in this purchase will be fully tax deductible over a period of 15 years.

We incurred approximately $5.1 million of transaction costs associated with this transaction prior to the closing date that are reflected in general and administrative expense and insurance and claims expense in the accompanying Consolidated Statements of Income for the year ended December 31, 2023.

The components of “Other intangibles” listed in the above table as of the acquisition date are preliminarily estimated based on prior final mile acquisitions as follows (in thousands):


			Accumulated		Balance at		Estimated Useful
	Amount		Amortization		December 31, 2023		Life
Customer relationships	$	127,733	$	355	$	127,378	15 years
Developed technology	$	6,723	$	70	$	6,653	4 years

The above intangible assets are amortized using the straight-line method. Amortization expense related to this acquisition for the year ended December 20, 2023 was $0.4 million. The intangible assets have a weighted average useful life of approximately 14.37 years.

Amortization expense related to FAFM for the next five years is as follows (in thousands):


	Total
2024	$	10,196
2025		10,196
2026		10,196
2027		10,126
2028		8,516

From the date of the acquisition through December 31, 2023, FAFM’s revenue was $6.4 million and operating income was $0.2 million.

FAFM's actual results are included in our consolidated financial statements since the acquisition date of December 20, 2023. The following unaudited pro forma consolidated results of operations present the effects of FAFM as though it had been acquired as of January 1, 2022 (in thousands, except for per share amounts):


	Twelve Months Ended		Twelve Months Ended
	December 31, 2023		December 31, 2022
Revenue	$	4,476,469	$	5,634,259
Net income	$	192,371	$	381,895
Earnings per share
Basic	$	3.04	$	5.75
Diluted	$	3.01	$	5.69

The unaudited pro forma consolidated results for the annual periods were prepared using the acquisition method of accounting and are based on the historical financial information of Hub and FAFM. The historical financial information has been adjusted to give effect to the pro forma adjustments that are: (i) directly attributable to the acquisition, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The unaudited pro forma consolidated results are not necessarily indicative of what our consolidated results of operations actually would have been had we completed the FAFM acquisition as of January 1, 2022.

Stock-Based Compensation Plans

NOTE 13. Stock-Based Compensation Plans

The 2022 Long-Term Incentive Plan (the “2022 Incentive Plan”) was approved by the Board of Directors and subsequently approved by the Company’s stockholders at the 2022 annual meeting. Upon stockholder approval of the 2022 Incentive Plan, no further grants were authorized under the Company’s 2017 Long-Term Incentive Plan (referred to herein as the “2017 Incentive Plan”). The 2022 Incentive Plan authorizes a broad range of awards including stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares or units, other stock-based awards, and cash incentive awards to all employees (including the Company’s executive officers), directors, consultants, independent contractors or agents of us or a related company. The 2022 Incentive Plan is effective as of May 24, 2022.

As of December 31, 2023, 2,888,438 shares were available for future grant under the 2022 Incentive Plan.

We have awarded time-based restricted stock to our employees and the Company’s non-employee directors (“Outside Directors”). This restricted stock generally vests ratably (once per year) over a three to five-year period for recipients other than Outside Directors. Outside Directors’ restricted stock vests over a one-year period. In 2023, 2022 and 2021, we also granted performance-based restricted stock to our executive officers. The performance-based restricted stock vests upon the third anniversary of its issuance if certain financial targets are achieved.

Share-based compensation expense for 2023, 2022 and 2021 was $21.2 million, $20.6 million and $20.1 million or $17.0 million, $15.7 million and $14.9 million, net of taxes, respectively. Included in the 2023, 2022 and 2021 share-based compensation expense was $6.3 million, $5.6 million and $5.8 million of performance-based share expenses or $4.8 million, $4.2 million and $4.3 million, net of taxes, respectively.

The fair value of non-vested restricted stock is equal to the market price of our stock at the date of grant.

The following table summarizes the non-vested restricted stock activity for the year ended December 31, 2023:


				Time-Based					Performance-Based
