Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. The preparation of financial statements in conformity with GAAP requires management 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 revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. In the opinion of management, the accompanying financial statements include all adjustments that are necessary for a fair statement of the results of the interim periods presented, such adjustments being of a normal recurring nature. Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2021 balance sheet was derived from our audited balance sheet as of that date. The Company’s operating results are subject to seasonal trends when measured on a quarterly basis; therefore operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2021. Impairment of Long Lived Assets The Company reviews its long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Expected future cash flows are used to analyze whether an impairment has occurred. If the sum of the expected undiscounted cash flows is less than the carrying value of the long-lived asset, then an impairment loss is recognized. We measure the impairment loss by comparing the fair value of the asset to its carrying value. Fair value is determined based on a discounted cash flow analysis or the appraised value of the assets, as appropriate. During the six months ended June 30, 2022, we incurred a non-cash adjustment of $2.2 million due to an obsolete technology write off and recognized $2.2 million in amortization expense. ​

The following table presents the provision for income taxes and the effective tax rates for the three and six months ended June 30, 2022 and 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ June 30, ​ June 30, ​ 2022 2021 2022 2021 Income (loss) before income tax provision (benefit) ​ $ 125 ​ $ 25,540 ​ $ (10,997) ​ $ 29,851 ​ Income tax provision (benefit) ​ 79 ​ 6,443 ​ (2,070) ​ 8,093 ​ Effective tax rate ​ ​ 63.2 % ​ 25.2 % ​ 18.8 % 27.1 % ​ The difference between the Company’s effective tax rate for the three and six months ended June 30, 2022 and 2021 and the US statutory rate of 21% primarily relates to nondeductible expenses, federal income tax credits, state income taxes (net of federal benefit), adjustments to valuation allowances, and certain discrete items.

Investments	4. Investments At March 31, 2021, we held a $5.0 million investment consisting of 353,604 shares in TuSimple, a self-driving technology company. Effective April 15, 2021, TuSimple completed their initial public offering at a closing price of $40.00 per share. As we have a readily determinable fair value based on quoted market prices, which makes this a Level 1 fair value measurement, we adjust the investment to fair value at each reporting period. We recognized an unrealized loss (gain) of $1.8 million and ($20.2) million during the three months ended June 30, 2022 and 2021, respectively, and $10.1 million and ($20.2) million during the six months ended June 30, 2022, and 2021, respectively, in other expense within the unaudited condensed consolidated statements of comprehensive income (loss). The fair value of the investment is $2.6 million and is included in other noncurrent assets on the accompanying unaudited consolidated balance sheets.

The Credit Facility is a $250.0 million revolving credit facility, with an uncommitted accordion feature that, so long as no event of default exists, allows the Company to request an increase in the revolving credit facility of up to $75.0 million. The Credit Facility is a five-year facility scheduled to terminate on January 28, 2025. Borrowings under the Credit Facility are classified as either “base rate loans” or “eurodollar rate loans”. Base rate loans accrue interest at a base rate equal to the highest of (A) the Federal Funds Rate plus 0.50%, (B) the Agent’s prime rate, and (C) LIBOR plus 1.00% plus an applicable margin that was set at 0.50% through June 30, 2020 and adjusted quarterly thereafter between 0.25% and 0.75% based on the ratio of the daily average availability under the Credit Facility to the daily average of the lesser of the borrowing base or the revolving credit facility. Eurodollar rate loans accrue interest at LIBOR plus an applicable margin that was set at 1.50% through June 30, 2020 and adjusted quarterly thereafter between 1.25% and 1.75% based on the ratio of the daily average availability under the Credit Facility to the daily average of the lesser of the borrowing base or the revolving credit facility. The Credit Facility includes, within its $250.0 million revolving credit facility, a letter of credit sub-facility in an aggregate amount of $75.0 million and a swingline sub-facility in an aggregate amount of $25.0 million. An unused line fee of 0.25% is applied to the average daily amount by which the lenders’ aggregate revolving commitments exceed the outstanding principal amount of revolver loans and aggregate undrawn amount of all outstanding letters of credit issued under the Credit Facility. The Credit Facility is secured by a pledge of substantially all of the Company’s assets, excluding, among other things, any real estate or revenue equipment financed outside the Credit Facility. Borrowings under the new Credit Facility are subject to a borrowing base limited to the lesser of (A) $250.0 million; or (B) the sum of (i) 87.5% of eligible billed accounts receivable, plus (ii) 85.0% of eligible unbilled accounts receivable (less than 30 days), plus (iii) 85.0% of the net orderly liquidation value percentage applied to the net book value of eligible revenue equipment, plus (iv) the lesser of (a) 80.0% the fair market value of eligible real estate or (b) $25.0 million. The Credit Facility contains a single springing financial covenant, which requires a consolidated fixed charge coverage ratio of at least 1.0 to 1.0. The financial covenant is tested only in the event excess availability under the Credit Facility is less than the greater of (A) 10.0% of the lesser of the borrowing base or revolving credit facility or (B) $20.0 million. Based on excess availability as of June 30, 2022, there was no fixed charge coverage ratio requirement. The Credit Facility includes usual and customary events of default for a facility of this nature and provides that, upon the occurrence and continuation of an event of default, payment of all amounts payable under the Credit Facility may be accelerated, and the lenders’ commitments may be terminated. The Credit Facility contains certain restrictions and covenants relating to, among other things, dividends, liens, acquisitions and dispositions, affiliate transactions, and other indebtedness. At June 30, 2022, the Credit Facility had issued collateralized letters of credit in the face amount of $28.3 million, with $69.2 million in borrowings outstanding and $152.5 million available to borrow.

Commitments and Contingencies	7. Commitments and Contingencies The Company is party to certain legal proceedings incidental to its business. The ultimate disposition of these matters, in the opinion of management, based in part on the advice of legal counsel, is not expected to have a materially adverse effect on the Company’s financial position or results of operations. For the cases described below, management is unable to provide a meaningful estimate of the possible loss or range of loss because, among other reasons, (1) the proceedings are in various stages; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of the proceedings, including pending appeals; and/or (5) there are significant factual issues to be resolved. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material adverse effect on our financial condition, though the outcomes could be material to our operating results for any particular period, depending, in part, upon the operating results for such period. California Wage and Hour Class Action Litigation On December 23, 2015, a former driver filed a class action lawsuit against the Company and its subsidiary U.S. Xpress, Inc. in the Superior Court of California, County of San Bernardino. The Company removed the case from state court to the U.S. District Court for the Central District of California. The district court denied plaintiff’s initial motion for class certification of a class comprised of any employee driver who has driven in California at any time since December 23, 2011, without prejudice, under Rule 23 due to lack of commonality amongst the putative class members. The Court granted the plaintiff’s revised Motion for Class Certification, and the certified class consists of all employee drivers who resided in California and who have driven in the State of California on behalf of U.S. Xpress, Inc. at any time since December 23, 2011. The case alleges that class members were not paid for off-the-clock work, were not provided duty free meal or rest breaks, and were not paid premium pay in their absence, were not paid the California minimum wage for all hours worked in that state, were not provided accurate and complete itemized wage statements and were not paid all accrued wages at the end of their employment, all in violation of California law. The class seeks a judgment for compensatory damages, penalties, injunctive relief, attorney fees, costs and pre- and post-judgment interest. On May 2, 2019, the district court dismissed the claims alleging failure to provide duty free meal and rest breaks or premium pay for failure to provide such breaks under California law on grounds of preemption. The Ninth Circuit Court of Appeals upheld the administrative ruling that formed the basis for the district court’s ruling. The parties filed cross-motions for summary judgment on the remaining claims, and the Company filed a motion to decertify the class. The court issued its ruling on the pending cross-motions: (1) the court denied the Company’s motion to decertify the class; (2) the court granted the Company’s motion for summary judgment on the plaintiff’s minimum wage claim for non-driving duties such as pre-trip and post-trip inspection, fueling, receiving dispatches, waiting to load or unload, and handling paperwork for the loads for January 1, 2013 forward (leaving the minimum wage claim only for the approximate one-year time period from December 23, 2011 to December 31, 2012); (3) the court granted the plaintiff’s motion for summary judgment for the time spent taking U.S. Department of Transportation-required 10-hour breaks while hauling high value loads in California for solo drivers and for the designated team driver responsible for the load during those breaks; and (4) the court denied the balance of cross-motions. The plaintiff filed a petition for permission to file an interlocutory appeal of the court’s decision on the minimum wage claim, which the district court and the Ninth Circuit both granted. On June 22, 2021, the Ninth Circuit issued its memorandum decision upholding the district court’s ruling in favor of the Company on the plaintiff’s claim for payment of the minimum wage for certain non-driving work they claim was left uncompensated by the Company’s piece rate pay plan after January 1, 2013. The district court held a status conference on June 15, 2021 and set a trial date for March 1, 2022. Discovery has been completed. On January 20, 2022, the court vacated the trial date and all associated deadlines due to the ongoing Covid-19 pandemic. On March 10, 2022, the court reset the trial for September 6, 2022. We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. The Company intends to vigorously defend the merits of these claims. Stockholder Claims As set forth below, between November 2018 and April 2019, eight substantially similar putative securities class action complaints were filed against the Company and certain other defendants: five in the Circuit Court of Hamilton County, Tennessee (“Tennessee State Court Cases”), two in the U.S. District Court for the Eastern District of Tennessee (“Federal Court Cases”), and one in the Supreme Court of the State of New York (“New York State Court Case”). We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any for these matters. We believe the allegations made in the complaints are without merit and intend to defend ourselves vigorously in these matters. As to the Tennessee State Court Cases, two of five complaints were voluntarily dismissed and the remaining three were consolidated with a Consolidated Amended Class Action Complaint (the “Consolidated State Court Complaint”) filed on May 10, 2019 in the Circuit Court of Hamilton County, Tennessee against the Company, five of our current and former officers or directors, and the seven underwriters who participated in our June 2018 initial public offering (“IPO”), alleging violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 (the “Securities Act”). The putative class action lawsuit is based on allegations that the Company made false and/or misleading statements in the registration statement and prospectus filed with the Securities and Exchange Commission (“SEC”) in connection with the IPO. The lawsuit is purportedly brought on behalf of a putative class of all persons or entities who purchased or otherwise acquired the Company’s Class A common stock pursuant and/or traceable to the IPO, and seeks, among other things, compensatory damages, costs and expenses (including attorneys’ fees) on behalf of the putative class. On June 28, 2019, the defendants filed a Motion to Dismiss the Tennessee State Court Cases for failure to allege facts sufficient to support a violation of Section 11, 12 or 15 of the Securities Act. On November 13, 2020, the court presiding over the Tennessee State Court Cases entered an order, granting in part and denying in part the defendants’ Motions to Dismiss the Consolidated State Court Complaint. The court held that the plaintiffs failed to state a claim for violation of the Securities Act with respect to the majority of statements challenged as false or misleading in the Consolidated State Court Complaint. The court, however, held that the Consolidated State Court Complaint sufficiently alleged violations of the Securities Act with respect to one statement from the June 2018 IPO registration statement and prospectus that the plaintiffs alleged to be false or misleading, both on theories of alleged misrepresentations and material omissions. Accordingly, the court allowed this action to proceed beyond the pleading stage, but only with respect to the statement deemed sufficient to support a Securities Act claim when assuming the truth of the plaintiffs’ allegations. On April 29, 2021, plaintiffs filed a Motion for Class Certification, which is currently pending. The Tennessee State Court Cases are currently in discovery. As to the Federal Court Cases, the operative amended complaint was filed on October 8, 2019 (“Amended Federal Complaint”), which named the same defendants as the Tennessee State Court Cases. The Amended Federal Complaint is made on behalf of a putative class. In addition to claims for alleged violations of Section 11 and 15 of the Securities Act, the Amended Federal Complaint alleges violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934 (“Exchange Act”) against the Company, its Chief Executive Officer and its Chief Financial Officer. On December 23, 2019, the defendants filed a Motion to Dismiss the Amended Federal Complaint in its entirety for failure to allege facts sufficient to state a claim under either the Securities Act or the Exchange Act. The plaintiffs filed their Opposition to that Motion on March 9, 2020, and the defendants filed their Reply brief on April 23, 2020. On June 30, 2020, the court presiding over the Federal Court Cases issued its ruling granting in part and denying in part the defendants’ Motions to Dismiss the Amended Federal Complaint. The court dismissed entirely the plaintiffs’ claims for alleged violations of the Exchange Act and further held that the plaintiffs failed to state a claim for violation of the Securities Act with respect to the majority of statements challenged as false or misleading in the Amended Federal Complaint. The court, however, held that the Federal Amended Complaint sufficiently alleged violations of the Securities Act with respect to two statements from the June 2018 IPO registration statement and prospectus that the plaintiffs alleged to be false or misleading, both on theories of alleged misrepresentations and material omissions. Accordingly, the court allowed this action to proceed beyond the pleading stage, but only with respect to the statements deemed sufficient to support a Securities Act claim when assuming the truth of the plaintiffs’ allegations. On February 12, 2021, the Court granted plaintiffs’ Motion for Class Certification and certified a class consisting of all persons or entities who purchased or otherwise acquired USX stock pursuant to and/or traceable to the IPO and who were damaged thereby. The Federal Court Cases are currently in discovery. As to the New York State Case, on March 14, 2019, a substantially similar putative class action complaint was filed in the Supreme Court of the State of New York, County of New York, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the Tennessee State Court Cases. On December 18, 2020, defendants filed a Motion to Dismiss or Stay the New York State Case both on the merits and in deference to the pending actions in Tennessee. On March 5, 2021, the court presiding over the New York State Case dismissed the case, and on January 13, 2022, the court entered a motion denying plaintiff’s motion for reconsideration. Stockholder Derivative Action On June 7, 2019, a stockholder derivative lawsuit was filed in the District Court for Clark County, Nevada against five of our executives and all five of our independent board members (collectively, the “Individual Defendants”), and naming the Company as a nominal defendant. The complaint alleges that the Company made false and/or misleading statements in the registration statement and prospectus filed with the SEC in connection with the IPO and that the Individual Defendants breached their fiduciary duties by causing or allowing the Company to make such statements. The complaint alleges that the Company has been damaged by the alleged wrongful conduct as a result of, among other things, being subjected to the time and expense of the securities class action lawsuits that have been filed relating to the IPO. In addition to a claim for alleged breach of fiduciary duties, the lawsuit alleges claims against the Individual Defendants for unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The parties have stipulated to a stay of this proceeding pending entry of a final judgment in the Tennessee State Court Cases, Federal Court Case, and the New York State Case. This matter is in the preliminary stages of litigation. We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. We believe the allegations made in the complaint are without merit and intend to defend ourselves vigorously in this matter. Other The Company had letters of credit of $28.3 million outstanding as of June 30, 2022. The letters of credit are maintained primarily to support the Company’s insurance program. The Company had cancelable commitments outstanding at June 30, 2022 to acquire revenue equipment and other equipment and terminal improvements for approximately $221.2 million during the remainder of 2022 and $6.6 million during 2023. These purchase commitments are expected to be financed by operating leases, long-term debt and proceeds from sales of existing equipment. ​

The Company had reserved an aggregate of 3.2 million shares of its Class A common stock for issuance of awards under the Incentive Plan. In May 2020, the stockholders approved the Amended and Restated Omnibus Plan which, among other things, increased the number of shares remaining to issue to 5.8 million shares. Participants in the Incentive Plan will be selected by the Compensation Committee from the executive officers, directors, employees and consultants of the Company. Awards under the Incentive Plan may be made in the form of stock options, stock appreciation rights, stock awards, restricted stock units, performance awards, performance units, and any other form established by the Compensation Committee pursuant to the Incentive Plan.

The fair value of the stock options granted was estimated using the Black-Scholes method as of the grant date. ​ At June 30, 2022, the Company had $0.1 million in unrecognized compensation expense related to the stock option awards which is expected to be recognized over a period of approximately 6 months. As of June 30, 2022, 270,092 options were exercisable with a weighted average exercise price of $12.64 and a weighted average remaining contractual life of 6.6 years.

At June 30, 2022, the Company had approximately $0.5 million in unrecognized compensation expense related to restricted units, which is expected to be recognized over a period of approximately 1.7 years. The fair value of the restricted units and corresponding compensation expense was determined using the income approach. ​ Employee Stock Purchase Plan In June 2018, our Employee Stock Purchase Plan (the “ESPP”) became effective. The Company has reserved an aggregate of 2.3 million shares of its Class A common stock for issuance under the ESPP. Eligible employees may elect to purchase shares of our Class A common stock through payroll deductions up to 15% of eligible compensation. The purchase price of the shares during each offering period will be 85% of the lower of the fair market value of our Class A common stock on the first trading day of each offering period or the last trading day of the offering period. The common stock will be purchased in January and July of each year. The Company recognized compensation expense of $0.3 million and $0.4 million for the three and six months ended June 30, 2022 and $0.1 million and $0.2 million during the three and six months ended June 30, 2021, respectively, associated with the plan.

Segment Information
Segment Information	10. Segment Information The Company’s business is organized into two reportable segments, Truckload and Brokerage. The Truckload segment offers asset-based truckload services, including OTR trucking and dedicated contract services. These services are aggregated because they have similar economic characteristics and meet the aggregation criteria described in the accounting guidance for segment reporting. The Company’s OTR service offering provides solo and expedited team services through one-way movements of freight over routes throughout the United States. The Company’s dedicated contract service offering devotes the use of equipment to specific customers and provides services through long-term contracts. The Company’s dedicated contract service offering provides similar freight transportation services, but does so pursuant to agreements where it makes equipment, drivers and on-site personnel available to a specific customer to address needs for committed capacity and service levels. The Company’s Brokerage segment is principally engaged in non-asset-based freight brokerage services, where it outsources the transportation of loads to third-party carriers. For this segment, the Company relies on brokerage employees to procure third-party carriers, as well as information systems to match loads and carriers.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. The preparation of financial statements in conformity with GAAP requires management 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 revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. In the opinion of management, the accompanying financial statements include all adjustments that are necessary for a fair statement of the results of the interim periods presented, such adjustments being of a normal recurring nature. Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2021 balance sheet was derived from our audited balance sheet as of that date. The Company’s operating results are subject to seasonal trends when measured on a quarterly basis; therefore operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2021.
Impairment of Long Lived Assets	Impairment of Long Lived Assets The Company reviews its long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Expected future cash flows are used to analyze whether an impairment has occurred. If the sum of the expected undiscounted cash flows is less than the carrying value of the long-lived asset, then an impairment loss is recognized. We measure the impairment loss by comparing the fair value of the asset to its carrying value. Fair value is determined based on a discounted cash flow analysis or the appraised value of the assets, as appropriate. During the six months ended June 30, 2022, we incurred a non-cash adjustment of $2.2 million due to an obsolete technology write off and recognized $2.2 million in amortization expense.
