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 by 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 August 22, 2022, we acquired TAGG Logistics, LLC (“TAGG”), o n October 19, 2021, we acquired Choptank Transport, LLC ("Choptank") and on December 9, 2020, we acquired NonstopDelivery, LLC (“NSD”). Refer to Note 4 “ Aquisitions ” 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, 2022 and 2021 , 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, 2022 and 2021. 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 $ 38.6 million and $ 20.1 million as of December 31, 2022 and 2021 , 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. We only have one reporting unit. 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 unit was less than its 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 a reporting unit to its fair value. If the fair value of the 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 2022 and 2021 as required and determined it was not more-likely-than-not that the fair value of our reporting unit 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, 2022 and 2021, we had an accrual of approxima tely $ 38.8 million an d $ 30.8 mil lion, respectively for estimated claims. We had no significant receivables recorded for payments in excess of our self-insu red 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, 2022, 2021 and 2020 , one customer accounted for more than 10 % of our annual revenue. We revie w 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. 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 $ 1.6 mill ion 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 . 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.

Acquisitions	NOTE 4. Acquisitions TAGG Logistics, LLC Acquisition On August 22, 2022 , we acquired 100 % of the equity interests of TAGG Logistics, LLC (“TAGG”), a provider of e-commerce, B2B and omnichannel fulfillment solutions, including warehousing and transportation services. Total consideration for the transaction was $ 103.4 million. $ 103.5 million was paid in cash during the third quarter of 2022 while $ 0.1 million is due back from the seller in the first quarter of 2023 as part of the post-closing true-up. TAGG is a nationwide provider with over 4 million square feet of warehousing space throughout the United States allowing for responsive e-commerce and B2B fulfillment services. The acquisition improved our presence in the consolidation and fulfillment space and added a complementary e-commerce offering to serve our customers' multimodal transportation and logistics needs. The acquisition added scale to our logistics service line and has resulted in complementary cross-selling opportunities. The initial accounting for the acquisition of TAGG 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 including the review of the applicable future cash flows used in determining the purchase accounting. As a result, the amounts recorded in the consolidated financial statements related to the TAGG acquisition are preliminary and the measurement period remains open. The following table summarizes the preliminary allocation of the total purchase consideration to the net assets acquired and liabilities assumed as of the date of the acquisition (in thousands): August 22, 2022 Cash and cash equivalents $ 839 Accounts receivable trade 24,409 Prepaid expenses and other current assets 2,024 Property and equipment 6,453 Right of use assets - operating leases 56,689 Other intangibles 27,300 Goodwill 52,062 Other assets 1,705 Total assets acquired $ 171,481 Accounts payable trade $ 9,497 Accrued payroll 2,500 Accrued other 1,373 Lease liability - operating leases short-term 14,465 Lease liability - operating leases long-term 40,254 Total liabilities assumed $ 68,089 Total consideration $ 103,392 Cash paid, net $ 102,661 The TAGG 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 August 22, 2022 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the TAGG 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 $ 3.1 million of transaction costs associated with this transaction prior to the closing date that are reflected in general and administrative expense in the accompanying Consolidated Statements of Income for the year ended December 31, 2022. The components of “Other intangibles” listed in the above table as of the acquisition date are summarized as follows (in thousands): Accumulated Balance at Estimated Useful Amount Amortization December 31, 2022 Life Customer relationships $ 22,600 $ 801 $ 21,799 10 years Developed technology $ 4,000 $ 288 $ 3,712 5 years Trade name $ 700 $ 168 $ 532 18 months The above intangible assets are amortized using the straight-line method.

Total consideration for the transaction was $ 127.6 million in cash and the settlement of accounts receivable due from Choptank of $ 0.3 million. In connection with the acquisition, we granted approximately $ 22 million of restricted stock to Choptank's owners and senior management team, which is subject to certain vesting conditions. The grants of restricted stock were made pursuant to award agreements and issued under our 2017 Long Term Incentive Plan. The acquisition of Choptank enhanced our refrigerated trucking transportation solutions offering and complemented our growing fleet of refrigerated intermodal containers. Choptank has developed a proprietary technology platform that we will leverage to enhance our truck brokerage service line.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	NOTE 5. Revenue from Contracts with Customers See Note 1 – Description of Business and Summary of Significant Accounting Policies for significant accounting policy for revenue. Hub offers comprehensive multimodal solutions throughout the United States, Canada and Mexico. As part of our profit improvement initiatives, we have focused on realizing efficiencies between our drayage trucking operation (which supports our intermodal service) and our dedicated trucking operation, including through the sharing of equipment and drivers, and by leveraging a combined set of driver support services including driver recruiting, asset management and safety functions. As a result, in 2022, we report revenue for these operations under the “Intermodal and Transportation Solutions” line of business. We have recast the prior period information to conform with current year presentation. We operate the following lines of business: Intermodal and transportation solutions. Our intermodal and transportation solutions line of business 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. Our service offering is well positioned to assist our customers in reducing their transportation spend and achieving their carbon emissions objectives. As an intermodal provider, we arrange for the movement of our customers’ freight in one of our containers, typically over long distances of 750 miles or more. We contract with railroads to provide transportation for the long-haul portion of the shipment between rail terminals. Local pickup and delivery services (referred to as “drayage”) between origin or destination and rail terminals are provided by our own trucking operations and third parties with whom we contract. Our predictive track and trace technology monitors the shipment to ensure that it arrives as scheduled and provides notification to our customer service personnel if there are service delays. During 2022, approximately 55 % of Hub’s drayage needs were provided by our own drivers and tractors, or by owner operators with whom we contracted. As of December 31, 2022, 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. 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. Truck Brokerage. We operate one of the largest truck brokerage operations in the United States, providing customers with a trucking option for their transportation needs. Our brokerage does not operate any trucks; instead we match customers’ needs with trucking carriers’ capacity to provide the most effective combination of service and price. We have contracts with a substantial base of carriers allowing us to meet the varied needs of our customers. Approximately half of our truck brokerage volume is generated from transactions in which we offer lane-based pricing at a fixed rate for periods of up to one year (referred to as “committed” pricing). The remaining portion of our volume is generated based on shorter term transactional lane-based rates (referred to as “transactional” pricing). In a typical truck brokerage transaction, the customer places an order with us for trucking transportation. We identify a third-party trucking carrier to handle the load and coordinate a delivery appointment. Once we receive confirmation that the freight has been picked up, we monitor the movement of the shipment until it reaches its destination and the delivery has been confirmed. We offer a full range of trucking transportation services, including dry van, expedited, less-than-truckload, refrigerated and flatbed. We substantially increased the size of our brokerage service line and increased our refrigerated transportation capabilities through the acquisition of Choptank in October 2021. Logistics . Our logistics business offers a wide range of transportation management services and technology solutions including shipment optimization, load consolidation, mode selection, carrier management, load planning and execution, and shipment visibility. We offer multi-modal transportation services including full truckload, LTL, intermodal, final mile, railcar, small parcel and international transportation. 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 intermodal and truck brokerage service lines. Our logistics offering also includes warehousing, fulfillment, cross-docking and consolidation services. Many of the customers for these solutions are consumer goods companies who sell into the retail channel. Our business operates or has access to approximately 9.5 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. In August 2022, we acquired TAGG which enhanced our presence in the consolidation and fulfillment space and added a complementary e-commerce offering to serve our customers' multimodal transportation and logistics needs. The acquisition added scale to our logistics service line and has resulted in cross-selling opportunities. In December 2020, we acquired NSD which added residential final mile transportation services to our logistics offering. Our final mile services include warehousing, product assembly, inbound transportation to warehouses, delivery of goods to residential locations, and revers e logistics services. Customers for our final mile services include retailers and consumer goods companies. We contract with nearly 200 vendors ac ross the United States who provide warehousing and transportation to support our final mile offering. The following table summarizes our disaggregated revenue by business line (in thousands) for the years ended December 31: 2022 2021 2020 Intermodal and transportation solutions $ 3,301,835 $ 2,656,128 $ 2,297,238 Truck brokerage 1,049,733 688,867 431,127 Logistics 988,922 887,388 767,279 Total revenue $ 5,340,490 $ 4,232,383 $ 3,495,644

Goodwill and Other Intangible Assets	NOTE 6. Goodwill and Other Intangible Assets In accordance with the FASB issued guidance in the Intangibles-Goodwill and Other Topic of the Codification, we completed the required annual impairment test. We performed a qualitative and quantitative assessment on goodwill and determined it was not more-likely-than-not that the fair value of our reporting unit 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 (in thousands): Goodwill Balance at December 31, 2020 $ 508,555 Acquisition $ 68,395 Other ( 37 ) Balance at December 31, 2021 $ 576,913 Acquisitions 52,489 Balance at December 31, 2022 $ 629,402 The change noted as “other” in the table above for 2021 refers to the amortization of the income tax benefit of tax goodwill in excess of financial statement goodwill. The components of the “Other intangible assets” are as follows (in thousands): Net Gross Accumulated Carrying Amount Amortization Value Life As of December 31, 2022: 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 5 - 7 years Trade name $ 6,200 $ 5,118 $ 1,082 18 months Total $ 280,923 $ 83,537 $ 197,386 Net Gross Accumulated Carrying Amount Amortization Value Life As of December 31, 2021: Customer relationships $ 226,623 $ 53,156 $ 173,467 5 - 15 years Carrier network and agent relationships $ 15,000 $ 1,063 $ 13,937 4 years Developed technology $ 6,500 $ 232 $ 6,268 7 years Trade name $ 5,500 $ 2,500 $ 3,000 18 months Total $ 253,623 $ 56,951 $ 196,672 The above intangible assets are amortized using the straight-line method. Amortization expense was $ 26.6 million and $ 18.7 million for the years ended December 31, 2022 and 2021 , respectively. The remaining weighted average life of all definite lived intangible assets was 9.57 years and 10.30 years for the years ended December 31, 2022 and 2021 , respectively. Amortization expense for the next five years is expected to be as follows (in thousands): Total Year 1 $ 26,810 Year 2 24,251 Year 3 23,149 Year 4 20,449 Year 5 20,160

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. We acquired a federal net operating loss carryforward of $ 4.1 million through the acquisition by way of merger with CaseStack, LLC in December 2018. The Internal Revenue Service ("IRS") loss limitation rules allowed us to utilize $ 1.3 million in each of the 2021, 2020 and 2019 tax years. The remaining net operating loss of $ 0.2 million was fully utilized in 2022. 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, 2023 , and December 31, 2041 . 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, 2023 , and December 31, 2027 . Management believes it is more likely than not that approximately $ 6.6 million of the incentive carryforward deferred tax assets will be realized and a valuation allowance of $ 1.6 million has been established for the remainder which are not expected to be realized. As of December 31, 2022 and December 31, 2021 , the amount of unrecognized tax benefits was $ 11.1 million and $ 6.6 million, respectively. If recognized, these benefits would decrease our income tax provision by $ 9.0 million and $ 5.4 million, respectively. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): 2022 2021 Gross unrecognized tax benefits - beginning of the year $ 6,647 $ 4,292 Gross increases related to prior year tax positions 425 997 Gross increases related to current year tax positions 4,665 1,794 Lapse of applicable statute of limitations ( 621 ) ( 436 ) Gross unrecognized tax benefits - end of year $ 11,116 $ 6,647 We recognize interest and penalties related to income tax liabilities in our provision for income taxes. In 2022, 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. Though some provisions of the CARES Act 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, 2022, December 31, 2021 or December 31, 2020. 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, the extension of which likewise did not have a material impact on the Company’s consolidated financial statements for the years ended December 31, 2022, December 31, 2021 or December 31, 2020. 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. As of December 31, 2022, we do not anticipate any material impact of these provisions which are effective January 1, 2023. 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.

Fair Value Measurement The carrying value of cash and cash equivalents, accounts receivable and accounts payable materially approximated fair value as of December 31, 2022 and 2021. As of December 31, 2022, the fair value of the Company’s fixed-rate borrowings was $ 11.7 million less than the historical carrying value of $ 342.5 million. As of December 31, 2021, the $ 274.8 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, 2022 and 2021, 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 $ 18.1 million and $ 24.3 million as of December 31, 2022 and 2021, 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.

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 2023 . As of December 31, 2022 and December 31, 2021, our letters of credit were $ 43.4 million and $ 41.3 million, respectively.

Leases [Abstract]
Leases	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, 2022, we recorded $ 103.3 million of ROU assets and $ 109.3 million of lease liabilities on our consolidated balance sheet. As of December 31, 2021, we recorded $ 45.3 million of ROU assets and $ 47.5 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, 2022, 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, 2022, 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 $ 74.4 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. The following table summarizes the lease costs (in thousands), which are included in transportation costs and general and administrative costs in the accompanying consolidated statement of income: Years Ended December 31, 2022 2021 2020 Amortization of finance right-of-use assets $ 2,075 $ 2,304 $ 2,309 Interest on finance lease liabilities 13 29 135 Finance lease cost 2,088 2,333 2,444 Operating lease cost 21,232 12,343 10,946 Short-term lease cost 379 171 238 Sublease income ( 251 ) ( 327 ) ( 469 ) Total lease cost $ 23,448 $ 14,520 $ 13,159 The following table represents the maturity of operating and finance lease liabilities (in thousands): December 31, 2022 Operating Leases Finance Leases Total Year 1 $ 33,547 $ 1,179 $ 34,726 Year 2 29,618 - 29,618 Year 3 24,081 - 24,081 Year 4 16,300 - 16,300 Year 5 9,136 - 9,136 Thereafter 5,618 - 5,618 Total 118,300 1,179 119,479 Imputed interest 10,196 4 10,200 Present value of lease payments 108,104 1,175 109,279 Less: current lease liabilities 29,547 1,175 30,722 Long-term lease liabilities $ 78,557 $ - $ 78,557 December 31, 2021 Operating Leases Finance Leases Total Year 1 $ 12,253 $ 1,257 $ 13,510 Year 2 9,904 - 9,904 Year 3 8,133 - 8,133 Year 4 6,842 - 6,842 Year 5 5,320 - 5,320 Thereafter 6,436 - 6,436 Total 48,888 1,257 50,145 Imputed interest 2,608 6 2,614 Present value of lease payments 46,280 1,251 47,531 Less: current lease liabilities 11,364 1,251 12,615 Long-term lease liabilities $ 34,916 $ - $ 34,916 The following table presents supplemental cash flow and noncash information related to leases: Years Ended December 31, 2022 2021 2020 Operating cash flows from operating leases $ 19,135 $ 11,523 $ 9,419 Financing cash flows from finance leases 2,093 2,682 3,066 Operating cash flows from finance leases 13 29 135 Cash paid for lease liabilities $ 21,241 $ 14,234 $ 12,620 Right-of-use assets obtained in exchange for new $ ( 2,017 ) $ ( 72 ) $ ( 71 ) financing lease liabilities (net of disposals) Rights-of-use assets obtained in exchange for new $ 77,178 $ 11,684 $ 17,875 operating lease liabilities (net of disposals) The weighted average remaining lease term and discount rates as of December 31, are as follows (in thousands): December 31, 2022 December 31, 2021 Weighted average remaining lease term — finance leases 0.6 years 0.6 years Weighted average remaining lease term — operating leases 4.06 years 5.11 years Weighted average discount rate — finance leases 1.20 % 1.56 % Weighted average discount rate — operating leases 4.51 % 2.14 %

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	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	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, 2022 and 2021 , 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	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, 2022 and 2021. 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 $ 38.6 million and $ 20.1 million as of December 31, 2022 and 2021 , 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 : 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	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 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. We only have one reporting unit. 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 unit was less than its 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 a reporting unit to its fair value. If the fair value of the 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 2022 and 2021 as required and determined it was not more-likely-than-not that the fair value of our reporting unit 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	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, 2022 and 2021, we had an accrual of approxima tely $ 38.8 million an d $ 30.8 mil lion, respectively for estimated claims. We had no significant receivables recorded for payments in excess of our self-insu red 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	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, 2022, 2021 and 2020 , one customer accounted for more than 10 % of our annual revenue. We revie w 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.
Revenue Recognition	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	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 $ 1.6 mill ion 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	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	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 .
Use of Estimates	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.
