NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Nature of Operations ​ Daseke, Inc.’s (the Company or Daseke) wholly-owned subsidiary Daseke Companies, Inc., was incorporated in December 2008 and began operations on January 1, 2009. Daseke is engaged in full service open-deck trucking that focuses primarily in flatbed truckload and heavy haul transportation of specialized items throughout the United States, Canada and Mexico. The Company also provides logistical planning and warehousing services to customers. The Company is subject to regulation by the Department of Transportation, the Department of Defense, the Department of Energy, and various state regulatory authorities in the United States. The Company is also subject to regulation by the Ministries of Transportation and Communications and various provincial regulatory authorities in Canada. ​ Basis of Presentation ​ These interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ended December 31, 2020. ​ The consolidated balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements at that date. For additional information, including the Company’s significant accounting policies, refer to the consolidated financial statements and related footnotes for the year ended December 31, 2019 as set forth in the Company’s Annual Report on Form 10-K, filed with the SEC on March 10, 2020. ​ Certain items have been reclassified for presentation purposes to conform to the accounting policies of the consolidated entity. These reclassifications had no material impact on income from operations, net income (loss) and comprehensive income (loss), the balance sheets or statements of cash flows. ​ Principles of Consolidation ​ The consolidated financial statements include the accounts of Daseke, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. ​ Use of Estimates ​ The preparation of the consolidated financial statements in accordance 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. ​ Deferred Financing Fees ​ In conjunction with obtaining long-term debt, the Company incurred financing costs which are being amortized using the straight-line method, which approximates the effective interest rate method, over the terms of the obligations. As of September 30, 2020 and December 31, 2019, the balance of deferred finance charges was $8.2 million and $11.4 million, respectively, which is included as a reduction of long-term debt, net of current portion in the consolidated balance sheets. Amortization expense was $1.1 million and $0.9 million for the three months ended September 30, 2020 and 2019, and $3.2 million and $2.4 million for the nine months ended September 30, 2020 and 2019, respectively. Amortization of deferred financing fees is included in interest expense in the consolidated statements of operations and comprehensive income (loss). ​ Impairment of Long-Lived Assets ​ Long-lived assets are reviewed for impairment at the asset group level whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the sum of the expected future undiscounted cash flow is less than the carrying amount of the asset, an impairment is indicated. A loss is then recognized for the difference, if any, between the fair value of the asset (as estimated by management using its best judgment) and the carrying value of the asset. If actual market value is less favorable than that estimated by management, additional write-downs may be required. In the nine months ended September 30, 2020, the Company recognized asset impairments, which are more fully described in Note 3. In the nine months ended September 30, 2019, the Company recognized asset impairments, which are more fully described in Notes 2, 5 and 7. ​ Fair Value Measurements ​ The Company follows the accounting guidance for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a framework for measuring fair value and expands disclosures about fair value measurements. The three levels of the fair value framework are as follows: ​ Level 1 Level 2 Level 3 ​ A financial asset or liability’s classification within the framework is determined based on the lowest level of input that is significant to the fair value measurement. ​ Contingent Consideration ​ The contingent consideration liabilities, included in other current liabilities on the consolidated balance sheets, represent future payment obligations for certain EBITDA thresholds related to the Company’s acquisitions over a defined period of time. The fair value of the Company’s contingent consideration liabilities are determined using estimates based on discount rates that reflect the risk involved and the projected EBITDA of the acquired businesses, therefore the liabilities are classified within Level 3 of the fair value framework. The balance of contingent consideration as of September 30, 2020 and December 31, 2019 was $21.2 million and $21.5 million, respectively. The table below is a summary of the changes in the fair value of this liability for the nine months ended September 30, 2020 and 2019 (in millions). The balance as of September 30, 2020 relates to the Aveda earnout discussed in Note 1 and Note 4 of the Company’s 2019 Annual Report on Form 10-K. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ ​ September 30, ​ 2020 2019 Balance at beginning of period ​ $ 21.5 ​ $ 21.9 Change in fair value ​ ​ (0.3) ​ ​ (0.4) Balance at end of period ​ $ 21.2 ​ $ 21.5 ​ Stock-Based Compensation ​ Awards of equity instruments issued to employees and directors are accounted for under the fair value method of accounting and recognized in the consolidated statements of operations and comprehensive income (loss). Compensation cost is measured for all stock-based awards at fair value on the date of grant and recognized using the straight-line method over the service period over which the awards are expected to vest. ​ Fair value of all time-vested options as of the date of grant is estimated using the Black-Scholes option valuation model, which was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Since the Company does not have a sufficient history of exercise behavior, expected term is calculated using the assumption that the options will be exercised ratably from the date of vesting to the end of the contractual term for each vesting tranche of awards. The risk-free interest rate is based on the U.S. Treasury yield curve for the period of the expected term of the stock option. For equity-classified awards, expected volatility is calculated using an index of publicly traded peer companies. For liability-classified awards, expected volatility is calculated using split and dividend adjusted closing stock prices over a lookback period commensurate with the remaining term of each award. ​ Fair values of non-vested stock awards (restricted stock units) are equal to the market value of the common stock on the date of the award with compensation costs amortized over the vesting period of the award. ​ Fair values of performance stock units are estimated using the Monte Carlo valuation model in a risk-neutral framework to model future stock price movements based upon highly subjective assumptions, including historical volatility, risk-free rates of return and the stock price simulated over the performance period. The risk-free interest rate is based on the interpolated constant maturity treasury curve for the performance period. Expected volatility is calculated using annualized historical volatility with a lookback period equal to the remaining performance period. ​ Segment Reporting ​ The Company determines its operating segments based on the information utilized by the chief operating decision maker to allocate resources and assess performance. Based on this information, the Company has determined it had 12 operating segments as of September 30, 2020 and 16 operating segments as of September 30, 2019 that are aggregated into two reportable segments: Flatbed Solutions, which delivers its services using primarily flatbed transportation equipment to meet the needs of high-volume, time-sensitive shippers, and Specialized Solutions, which delivers transportation and logistics solutions for super heavy haul, high-value customized and over-dimensional loads, many of which require engineering and customized equipment. ​ Earnings (loss) Per Share ​ Basic earnings (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share reflect the potential dilution of earnings per share that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the Company’s income (loss). ​ Common Stock Purchase Warrants ​ The Company accounts for the issuance of common stock purchase warrants in connection with equity offerings in accordance with the provisions of the Accounting Standards Codification (ASC) 815, Derivatives and Hedging (Topic 815). The Company classifies as equity any contract that (i) requires physical settlement or net-share settlement or (ii) gives the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies as assets or liabilities any contract that (i) requires net-cash settlement (including a requirement to net-cash settle the contract if an event occurs and if that event is outside the control of the Company) or (ii) gives the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). See Note 11 for additional details on the common stock purchase warrants. ​ The Company assessed the classification of its common stock purchase warrants and determined that such instruments meet the criteria for equity classification at the time of issuance. ​ Foreign Currency Gains and Losses ​ The functional currency for all operations except Canada is the U.S. dollar. The local currency is the functional currency for the Company’s operations in Canada. For these operations, assets and liabilities are translated at the rates of exchange on the consolidated balance sheet date, while income and expense items are translated at average rates of exchange during the period. The resulting gains or losses arising from the translation of accounts from the functional currency into U.S. dollars are included as a separate component of stockholders’ equity in accumulated other comprehensive income (loss) until a partial or complete liquidation of the Company’s net investment in the foreign operation. ​ From time to time, the Company’s foreign operations may enter into transactions that are denominated in a currency other than their functional currency. These transactions are initially recorded in the functional currency of the operating company based on the applicable exchange rate in effect on the date of the transaction. Monthly, these transactions are remeasured to an equivalent amount of the functional currency based on the applicable exchange rate in effect on the remeasurement date. Any adjustment required to remeasure a transaction to the equivalent amount of functional currency is recorded in the consolidated statements of operations and comprehensive income (loss) of the foreign operating company as a component of foreign exchange gain or loss. ​ Revenue and Expense Recognition ​ The Company’s revenue and related costs are recognized when the Company satisfies its performance obligation(s) transferring goods or services to the customer and the customer obtains control of such goods and services. With respect to freight, brokerage, logistics and fuel surcharge revenue, these conditions are met, and the Company recognizes company freight, owner operator freight, brokerage and fuel surcharge revenue, over time, and logistics revenue, as the services are provided. While the Company may enter into master service agreements with its customers, a contract is not established until the customer specifically requests the Company’s services and the Company accepts. The Company evaluates each contract for distinct performance obligations. In the Company’s business, a typical performance obligation is the transportation of a load including any highly interrelated ancillary services. The Company predominantly estimates the standalone selling price of its services based upon observable evidence, market conditions and other relevant inputs. The Company allocates the total transaction price to each distinct performance obligation based upon the relative standalone selling prices. ​ The Company’s customers simultaneously receive and consume the benefits of the Company’s contracts; therefore, revenue is recognized over time. This is a faithful depiction of the satisfaction of the performance obligation, as the customer does not need to re-perform the transportation services the Company has provided to date. ​ Generally, the Company’s customers are billed upon delivery of the freight or monthly and remit payment according to the approved payment terms. ​ Freight Revenue ​ Freight revenue is generated by hauling customer freight using company owned equipment (company freight) and owner-operator equipment (owner-operator freight). Freight revenue is the product of the number of revenue-generating miles driven and the rate per mile received from customers plus accessorial charges, such as loading and unloading freight, cargo protection, fees for detained equipment or fees for route planning and supervision. ​ Brokerage Revenue The Company regularly engages third-party capacity providers to haul loads. The Company is primarily responsible for fulfilling the promise to provide load transportation services, and has discretion in setting prices, along with the risk to fulfill the contract to the customer. Based upon this evaluation, the Company has determined that it is the principal and therefore, records gross revenues and expenses for brokerage services. ​ Logistics Revenue ​ Logistics revenue is generated from a range of services, including value-added warehousing, loading and unloading, vehicle maintenance and repair, preparation and packaging, fuel management, and other fleet management solutions. The Company recognizes logistics revenue as services are completed. ​ Fuel Surcharge ​ Fuel surcharge revenue compensates the Company for fuel costs above a certain cost per gallon base. Generally, the Company receives fuel surcharges on the miles for which it is compensated by customers. ​ Practical expedients ​ The Company has designated the following preference and practical expedients: ​ ● To not disclose remaining performance obligations when the expected performance obligation duration is one year or less. The vast majority of the Company’s services transfer control within a month of the inception of the contract with select specialized loads taking several months to allow for increased planning and permitting. ​ ● Recognize the incremental costs of obtaining or fulfilling a contract as an expense when incurred, as the amortization period of a potential asset would be recognized in one year or less. ​ ● Exclude taxes collected on behalf of government authorities from the Company’s measurement of transaction prices. Tax amounts are not included within net income (loss) or cost of sales. ​ Lease Accounting ​ Lessee ​ The Company has capitalized operating and finance leases for various real estate including corporate offices, trucking facilities and terminals, warehouses, and tractor parking as well as various types of equipment including tractors, trailers, forklifts, and office equipment. New real estate lease agreements will typically have initial terms have terms ​ Some of the Company’s leases include one or more options to renew, with renewals that can extend the lease from ​ The Company determines whether an arrangement is classified as a lease at inception. The right-of-use assets and lease liabilities relating to operating leases are included in right-of-use assets, other current liabilities, and other long-term liabilities on the Company's consolidated balance sheets. The right-of-use assets and lease liabilities relating to finance leases are included in other long-term assets, current portion of long-term debt, and long-term debt, net of current portion on the Company's consolidated balance sheets. The Company's right-of-use assets represent its right to use the underlying assets for the lease term and the Company's right-of-use liabilities represent its obligation to make lease payments arising from the leases. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company's capitalized operating lease agreements generally do not provide an implicit rate. The Company developed an incremental borrowing rate based on the information available at the commencement date regarding the interest rate applicable to collateralized borrowings for a period similar to the original lease period. The incremental borrowing rates were used in determining the present value of lease payments which is reflected as the lease liability. ​ Lessor ​ The Company leases tractors and trailers to certain of its owner-operators and accounts for these transactions as operating leases. These leases typically have terms of 30 ​ The Company recorded depreciation expense of $4.4 million and $5.7 million for the three months ended September 30, 2020 and 2019, $12.7 million and $16.4 million for the nine months ended September 30, 2020 and 2019 on its assets leased under operating leases, respectively. Lease income from lease payments related to the Company's operating leases for the three months ended September 30, 2020 and 2019, was $6.1 million and $6.5 million, and for the nine months ended September 30, 2020 and 2019 was $18.5 million and $18.0 million, respectively. ​ The Company has designated the following preferences and practical expedients: ​ ● Adopt the land easement practical expedient; ​ ● To not separate the non-lease components of a contract from the lease component for its office equipment asset class; ​ ● To not apply the recognition requirements to leases with terms of twelve months or less; and ​ ● To apply the portfolio approach in determination of the incremental borrowing rate. ​ New Accounting Pronouncements ​ In August 2020, the FASB issued ASU 2020-06 – Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The guidance simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separately present certain conversion features in equity. In addition, the amendments also simplify the guidance in ASC Subtopic 815-40, ​ In March 2020, the FASB issued ASU 2020-04 – ​ In December 2019, the FASB issued ASU No. 2019 - 12 – Income Taxes (Topic 740 ). Simplifying the Accounting for Income Taxes, as part of its initiative to reduce complexity in the accounting standards. The amendments in ASU 2019 - 12 eliminate certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019 - 12 also clarifies and simplifies other aspects of the accounting for income taxes. The amendments in ASU 2019 - 12 will become effective for the Company on January 1, 2022 . Early adoption is permitted, including adoption in any interim period. ​ In June 2016, the FASB issued ASU No. 2016-13 – The ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets, including trade receivables. The new standard will become effective for the Company beginning with the first quarter 2023 and is not expected to have a material impact on the Company’s consolidated financial statements.

The Plan was implemented to streamline and reduce the Company’s cost structure, improve asset utilization and capitalize on operational synergies. Additionally, the Company announced the planned implementation of Business Improvement Plans (BIP), which is expected to increase profitability by right-sizing trailer-to-tractor ratios, yielding management capacity allocations, and improving maintenance execution. ​ The Company implemented Project Synchronize and Project Pivot which resulted in recording of integration and restructuring costs. The integration and restructuring costs consist of asset impairments, employee-related costs, other transition and termination costs related to restructuring activities. Employee-related costs include severance, tax preparation, and relocation costs. Severance and relocation costs are expensed in accordance with ASC 420. Other transition and termination costs include fixed asset-related charges, contract and lease termination costs, professional fees, and other miscellaneous expenditures associated with the integration or restructuring activities, which are expensed as incurred. Costs are reported in restructuring charges in the consolidated statements of operations and comprehensive income (loss). The obligation related to employee separation costs is included in other current liabilities in the consolidated balance sheets. ​ On March 10, 2020, the Company announced a plan to integrate three operating segments with three other operating segments (Phase II of the Plan), which will further reduce the number of operating segments from 13 to 10. Phase II was initially expected to be significantly completed by June 30, 2020, however, due to uncertainties and changes in focus caused by the COVID-19 pandemic, the Company now expects Phase II to be completed by early 2021. The Company is in the process of determining the estimated impact of Phase II on the financial statements. Upon completion of Phase II of the Plan and the finalization of the Aveda divestiture, our operating segments will be reduced to 9. ​ During the first quarter of 2020, the Company made the decision to close certain of the Aveda terminals and wind down those operations. The Company recorded $4.5 million and $7.7 million of restructuring and exit costs in connection with the closure of these terminals in the three and nine months ended September 30, 2020, respectively.

Term loans under the Term Loan Facility are, at the Company’s election from time to time, comprised of alternate base rate loans (an ABR Borrowing) or adjusted LIBOR loans (a Eurodollar Rate Borrowing), with the applicable margins of interest being an alternate base rate (subject to a 2.00% floor) plus 4.00% per annum and LIBOR (subject to a 1.00% floor) plus 5.00% per annum. At September 30, 2020, the average interest rate on the Term Loan Facility was 6.2%. The Term Loan Facility is secured by all assets of the Company, except those assets collateralizing equipment and certain real estate lenders’ debt and subject to certain customary exceptions. ​ The Term Loan Facility contains a financial covenant requiring the Company to maintain a consolidated total leverage ratio as of the last day of any fiscal quarter of less than or equal to 4.00 to 1.00, stepping down to 3.75 to 1.00 on March 31, 2021. The consolidated total leverage ratio is defined as the ratio of (i) consolidated total debt minus unrestricted cash and cash equivalents and cash and cash equivalents restricted in favor of the administrative agent and the lenders, to (ii) consolidated Adjusted EBITDA for the trailing 12 month period (with customary add-backs permitted to consolidated Adjusted EBITDA, including in respect of synergies and cost-savings reasonably identifiable and factually supportable that are anticipated to be realized in an aggregate amount not to exceed 25% of consolidated Adjusted EBITDA and subject to other customary limitations). ​ The Term Loan Facility permits voluntary prepayments of borrowings. In certain circumstances (subject to exceptions, exclusions and, in the case of excess cash flow, step-downs described below), the Company may also be required to make an offer to prepay the Term Loan Facility if it receives proceeds as a result of certain asset sales, debt issuances, casualty or similar events of loss, or if it has excess cash flow (defined as an annual amount calculated using a customary formula based on consolidated Adjusted EBITDA, including, among other things, deductions for (i) the amount of certain voluntary prepayments of the Term Loan Facility and (ii) the amount of certain capital expenditures, acquisitions, investments and restricted payments). The percentage of excess cash flow that must be applied as a mandatory prepayment is 50%, 25% or 0% for excess cash flow periods for the year ending December 31, 2019 and beyond, depending upon the first lien leverage ratio. ​ The Term Loan Facility contains (i) certain customary affirmative covenants that, among other things, require compliance with applicable laws, periodic financial reporting and notices of material events, payment of taxes and other obligations, maintenance of property and insurance, and provision of additional guarantees and collateral, and (ii) certain customary negative covenants that, among other things, restrict the incurrence of additional indebtedness, liens on property, sale and leaseback transactions, investments, mergers, consolidations, liquidations and dissolutions, asset sales, acquisitions, the payment of distributions, dividends, redemptions and repurchases of equity interests, transactions with affiliates, prepayments and redemptions of certain other indebtedness, burdensome agreements, holding company limitations, changes in fiscal year and modifications of organizational documents. ​ ABL Facility ​ The Company has a five-year , senior secured asset-based revolving line of credit with an aggregate maximum credit amount equal to $100.0 million (subject to availability under a borrowing base equal to 85% of the Company’s eligible accounts receivable, 80% of the Company’s eligible unbilled accounts receivable and 50% of parts supplies) under a credit agreement with PNC Bank, National Association, as administrative agent and the lenders party thereto. The ABL Facility’s maximum credit amount may be increased by $30.0 million pursuant to an uncommitted accordion. The ABL Facility also provides for the issuance of letters of credit subject to certain restrictions and a sublimit of $20 million, as defined in the credit agreement. The ABL Facility matures on February 27, 2022. As of September 30, 2020, the Company had a debit balance of $0.8 million which is included in cash and cash equivalents, $16.2 million in letters of credit outstanding, and could incur approximately $82.4 million of additional indebtedness under the ABL Facility. ​ Borrowings under the ABL Facility bear interest at rates based upon the Company’s fixed charge coverage ratio and, at the Company’s election from time to time, either a base rate plus an applicable margin or an adjusted LIBOR rate plus an applicable margin. Margins on the ABL Facility are adjusted, if necessary to the applicable rates set forth in the following table corresponding to the fixed charge coverage ratio for the trailing 12 month period on the last day of the most recently completed fiscal quarter. ​ ​ ​ ​ ​ ​ ​ Fixed Charge Coverage Ratio ​ Base Rate Margins ​ LIBOR Rate Margins ​ Less than 1.25 to 1.00 ​ 2.25 % 3.25 % Greater than or equal to 1.25 to 1.00, but less than 1.50 to 1.00 ​ 1.75 % 2.75 % Greater than or equal to 1.50 to 1.00, but less than 1.75 to 1.00 ​ 1.25 % 2.25 % Greater than or equal to 1.75 to 1.00 ​ 0.75 % 1.75 % ​ The ABL Facility margins are adjusted to the applicable rates set forth in the following table corresponding to the average RLOC Utilization for the trailing 12 month period on the last day of the most recently completed fiscal quarter. RLOC Utilization at a particular date shall mean an amount equal to (a)(i) outstanding amount of Revolving Advances plus (ii) the outstanding amount of the Swing Loans plus (iii) the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, divided by (b) Maximum Revolving Advance Amount, each as defined in the credit agreement. ​ ​ ​ ​ ​ ​ ​ RLOC Utilization ​ Base Rate Margins ​ LIBOR Rate Margins ​ Less than 33.3% 0.50 % 1.50 % Greater than or equal to 33.3%, but less than 66.6% 0.75 % 1.75 % Greater than or equal to 66.6% 1.00 % 2.00 % ​ At September 30, 2020, the interest rate on the ABL Facility was 3.75%. ​ The ABL Facility is secured by all of the Company’s U.S.-based accounts receivable, parts supplies, cash and cash equivalents excluding proceeds of Term Loan Facility, securities and deposit accounts and other general assets not included in the Term Loan Facility collateral. The ABL Facility contains (i) a financial covenant similar to the consolidated total leverage ratio required under the Term Loan Facility requiring a leverage ratio of less than or equal to 4.00 to 1.00 for the fiscal quarter, stepping down to 3.75 to 1.00 on March 31, 2021 and (ii) during any period after a default or event of default or after excess availability falling below the greater of (x) $15.0 million and (y) 20% of the maximum credit amount, continuing until such time as no default or event of default has existed and excess availability has exceeded such amounts for a period of 60 consecutive days, a financial covenant requiring the Company to maintain a minimum consolidated fixed charge coverage ratio of 1.00 x, tested on a quarterly basis. The Company’s fixed charge coverage ratio is defined as the ratio of (1) consolidated Adjusted EBITDA minus unfinanced capital expenditures, cash taxes and cash dividends or distributions, to (2) the sum of all funded debt payments for the four-quarter period then ending (with customary add-backs permitted to consolidated Adjusted EBITDA). ​ The ABL Facility contains affirmative and negative covenants similar to those in the Term Loan Facility, together with such additional terms as are customary for a senior secured asset-based revolving credit facility. As of September 30, 2020, the Company was in compliance with all covenants contained in the Term Loan and ABL Facilities. ​ Equipment Term Loans and Mortgages ​ As of September 30, 2020, the Company had term loans collateralized by equipment in the aggregate amount of $171.7 million with 32 lenders (Equipment Term Loans). The Equipment Term Loans bear interest at rates ranging from 1.5% to 10.7%, require monthly payments of principal and interest and mature at various dates through January 2028. Certain of the Equipment Term Loans contain conditions, covenants, representations and warranties, events of default, and indemnification provisions applicable to the Company and certain of its subsidiaries that are customary for equipment financings, including, but not limited to, limitations on the incurrence of additional debt and the prepayment of existing indebtedness, certain payments (including dividends and other distributions to persons not party to its credit facility) and transfers of assets. As of September 30, 2020, the Company has a bank mortgage loan with a balance of $2.4 million incurred to finance the construction of the headquarters and terminal in Redmond, Oregon. The mortgage loan is collateralized by such property and buildings. The mortgage is payable in monthly installments of $15,776, including interest at 3.7% through November 2020 and will drop to $15,462 per month starting December 1, 2020. The interest rate and monthly payments is adjusted on November 1, 2020 to a rate of 3.7%, which is based on an index value of 0.53% plus margin of 2.5% rounded up to the nearest 0.125%. The bank mortgage loan matures November 1, 2023. ​ Future Payments ​ Future principal payments on long-term debt (excluding future payments on capital leases which are disclosed in Note 2) as of September 30, 2020 are as follows (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Twelve months ending September 30, Term Loan Facility Equipment Term Loans Total ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 $ 5.0 ​ $ 42.8 ​ $ 47.8 2022 ​ 2.5 ​ ​ 40.7 ​ ​ 43.2 2023 ​ 2.5 ​ ​ 32.8 ​ ​ 35.3 2024 ​ 474.2 ​ ​ 34.8 ​ ​ 509.0 2025 ​ 0.6 ​ ​ 16.0 ​ ​ 16.6 Thereafter ​ — ​ ​ 7.0 ​ ​ 7.0 Total long-term debt $ 484.8 ​ $ 174.1 ​ $ 658.9 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

As of September 30, 2020, the Company has no common stock reserved for future issuances of stock options and restricted stock units under the Company’s 2017 Omnibus Incentive Plan. See Note 12 for additional details about the Company’s stock-based compensation plan and liability classification for the awards for which sufficient shares are not available for issuance. ​ Preferred Stock ​ The Company has issued and outstanding 650,000 shares of Series A Preferred Stock with a redemption value of $65.0 million. The par value of Series A Preferred Stock is $0.0001 per share. Additional features of this preferred stock are as follows: Under the Certificate of Designations, Preferences, Rights and Limitations of the Series A Preferred Stock (the Certificate of Designations), each share of Series A Preferred Stock will be convertible, at the holder’s option at any time, initially into approximately 8.6957 shares of the Company’s common stock (assuming a conversion price of approximately $11.50 per share), subject to specified adjustments as set forth in the Certificate of Designations. If any holder elects to convert its Series A Preferred Stock after the seven-year anniversary of the issue date, if the then-current Conversion Price (as defined in the Certificate of Designations) exceeds the Weighted Average Price (as defined in the Certificate of Designations) for the common stock during any ten consecutive Trading Days (as defined in the Certificate of Designations), at its option by delivery of a Notice of Conversion in accordance with Section 8(b) of the Certificate of Designations no later than five business days following such tenth consecutive Trading Day, to convert any or all of such holder’s shares of Series A Preferred Stock into, at the Company’s sole discretion, either common stock, cash or a combination of common stock and cash; provided, that the Company shall provide such converting holder notice of its election within two Trading Days of receipt of the Notice of Conversion; provided further, that in the event the Company elects to issue common stock for all or a portion of such conversion, the Conversion Rate for such conversion (subject to the limitations set forth in Section 11 of the Certificate of Designations) shall mean the quotient of the Liquidation Preference (as defined in the Certificate of Designations) divided by the average Weighted Average Price for the common stock during the 20 consecutive Trading Days commencing on the Trading Day immediately following the Trading Day on which the Company provided such notice. If the Company does not elect a settlement method prior to the deadline set forth in the Certificate of Designations, the Company shall be deemed to have elected to settle the conversion entirely in common stock. Based on the assumed conversion rate, a total of 5,652,173 shares of common stock would be issuable upon conversion of all of the currently outstanding shares of Series A Preferred Stock. On or after the third anniversary of the initial issuance date but prior to the fifth anniversary of the initial issuance date, the Company will have the right, at its option, to give notice of its election to cause all outstanding shares of the Series A Preferred Stock to be automatically converted into shares of the Company’s common stock at the then-effective conversion rate, if the Weighted Average Price of Company’s common stock equals or exceeds 140% of the then-current conversion price for at least 20 -trading days (whether or not consecutive) in a period of 30 consecutive trading days. On or after the fifth anniversary of the initial issuance date but prior to the seventh anniversary of the initial issuance date, the Company will have the right, at its option, to give notice of its election to cause all outstanding shares of the Series A Preferred Stock to be automatically converted into shares of Company’s common stock at the then-effective conversion rate, if the Weighted Average Price of Company’s common stock equals or exceeds 115% of the then-current conversion price for at least 20 -trading days (whether or not consecutive) in a period of 30 consecutive trading days. On or after the seventh anniversary of the initial issuance date, the Company will have the right, at its option, to give notice of its election to cause all outstanding shares of the Series A Preferred Stock to be automatically converted into shares of Company’s common stock at the then-effective conversion rate, if the Weighted Average Price of Company’s common stock equals or exceeds the then-current conversion price for at least 10 consecutive trading days. If the Company undergoes certain fundamental changes (as more fully described in the Certificate of Designations but including, among other things, certain change-in-control transactions, recapitalizations, asset sales and liquidation events), each outstanding share of Series A Preferred Stock may, within 15 days following the effective date of such fundamental change and at the election of the holder, be converted into Company’s common stock at a conversion rate (subject to certain adjustments) equal to (i) the greater of (A) the sum of the conversion rate on the effective date of such fundamental change plus the additional shares received by holders of Series A Preferred Stock following such fundamental change (as set forth in the Certificate of Designations) and (B) the quotient of (x) $100.00 , divided by (y) the greater of (1) the applicable holder stock price and (2) 66 2/3% of the closing sale price of the Company’s common stock on the issue date plus (ii) the number of shares of Company’s common stock that would be issued if any and all accumulated and unpaid dividends were paid in shares of Company’s common stock. The Series A Preferred Stock contains limitations that prevent the holders thereof from acquiring shares of the Company’s common stock upon conversion that would result in (i) the number of shares beneficially owned by such holder and its affiliates exceeding 9.99% of the total number of shares of the Company’s common stock then outstanding or (ii) the Series A Preferred Stock being converted into more than 19.99% of the shares of the Company’s common stock outstanding on the initial issue date of the Series A Preferred Stock (subject to appropriate adjustment in the event of a stock split, stock dividend, combination or other similar recapitalization) without, in the latter instance, stockholder approval of such issuance. ​ Additional features of the Series A Preferred Stock are as follows: ​ Liquidation – In the event of liquidation, holders of Series A Preferred Stock have preferential rights to liquidation payments over holders of common stock. Holders of Series A Preferred Stock shall be paid out of the assets of the Company at an amount equal to $100 per share plus all accumulated and unpaid dividends. ​ Dividends – Dividends on the Series A Preferred Stock are cumulative at the Dividend Rate. The “Dividend Rate” is the rate per annum of 7.625% per share of Series A Preferred Stock on the liquidation preference ( $100 per share). Dividends are payable quarterly in arrears in cash or, at the Company’s election and subject to the receipt of the necessary shareholder approval (to the extent necessary), in shares of the Company’s common stock.

The Company also issued 15,080,756 warrants (the Private Placement Warrants) to the sponsor in a private placement that closed simultaneously with the consummation of the IPO. Each warrant entitles the registered holder to purchase one-half of one share of the Company’s common stock at a price of $5.75 per one-half of one share ( $11.50 per whole share), subject to adjustment. The warrants may be exercised only for a whole number of shares of the Company’s common stock. No fractional shares will be issued upon exercise of the warrants. The warrants will expire on February 27, 2022, five years after the completion of the merger with Hennessy, or earlier upon redemption or liquidation. The warrants are listed on the NASDAQ market under the symbol DSKEW. ​ The Company may call the Public Warrants for redemption at a price of $0.01 per warrant if, and only if, the reported last sale price of the Company’s common stock equals or exceeds $24.00 per share for any 20 -trading days within a 30 -trading day period ending on the third trading day prior to the date the Company sends the notice of redemption to the Public Warrant holders. ​

Under the Plan, the Company is authorized to issue up to 4.5 million shares of common stock. As of September 30, 2020, the Company has no common stock reserved for future issuances of stock options and restricted stock units under the Company’s 2017 Omnibus Incentive Plan. During the nine months ended September 30, 2020, the Company issued 901,200 of stock options and 2,037,300 of p erformance stock units (“PSUs”) three five o ne ​ Stock-based compensation cost with equity classification is measured at the grant date, based on the estimated fair value of the award, and is recognized on a straight-line basis as expense over the employees’ requisite service period. Forfeitures are recorded as a cumulative adjustment to stock-based compensation expense in the period forfeitures occur. Aggregate stock-based compensation charges, net of forfeitures, were $1.0 million and $1.0 million during the three months ended September 30, 2020 and 2019, respectively, and $3.0 million and $2.9 million during the nine months ended September 30, 2020 and 2019, respectively. These expenses are included as a component of salaries, wages and employee benefits on the accompanying consolidated statements of operations and comprehensive income (loss). As of September 30, 2020, there was $3.3 million and $3.0 million of unrecognized stock-based compensation expense related to stock options and restricted stock units, respectively. This expense will be recognized over the weighted average periods of 2.2 years for stock options and 1.7 years for restricted stock units. ​ Stock-based compensation cost with liability classification is recognized on a straight-line basis over the vesting period and revalued on each balance sheet date with the corresponding adjustment to stock-based compensation recorded in the consolidated statements of operations and comprehensive income (loss). As of September 30, 2020, the total fair value of the liability-classified stock options and PSU’s was $4.0 million and $10.2 million, respectively. As of September 30, 2020, share-based payment liability was $0.5 million and $1.4 million for liability-classified stock options and PSUs, respectively. ​ ​ Stock Options ​ The following table summarizes stock option grants: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Grantee Type # of Issued and Vesting Weighted Weighted Average ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Director Group ​ 150,000 ​ 100,000 ​ 5 years ​ $ 9.98 ​ $ 4.36 Employee Group ​ 4,596,030 ​ 4,097,122 ​ 3-5 years ​ $ 5.58 ​ $ 2.45 Total ​ ​ ​ 4,197,122 ​ ​ ​ ​ ​ ​ ​ ​ ​ *Included 901,200 stock option classified as liability granted to employee group. ​ The Company’s calculations of the fair value of stock options granted as equity classification during the nine months ended September 30, 2020 were made using the Black-Scholes option-pricing model. The fair value of the Company’s stock option grants was estimated utilizing the following assumptions: ​ ​ ​ ​ Weighted average expected life 6.0 years Risk-free interest rate ​ 0.43% Expected volatility ​ 41.04% Expected dividend yield ​ 0.00% ​ Since the Company does not have a sufficient history of exercise behavior, expected term is calculated using the assumption that the options will be exercised ratably from the date of vesting to the end of the contractual term for each vesting tranche of awards. The risk-free interest rate is based on the U.S. Treasury yield curve for the period of the expected term of the stock option. For equity-classified awards, expected volatility is calculated using an index of publicly traded peer companies. For liability-classified awards, expected volatility is calculated using split and dividend adjusted closing stock prices over a lookback period commensurate with the remaining term of each award. ​ During the nine months ended September 30, 2020, the Company issued 901,200 of stock options classified as liability and the fair value was calculated using Black-Scholes option-pricing model.

REPORTABLE SEGMENTS	NOTE 15 – REPORTABLE SEGMENTS ​ The Company evaluates the performance of the segments primarily based on their respective revenues and operating income. Accordingly, interest expense and other non-operating items are not reported in segment results. In addition, the Company has disclosed a corporate segment, which is not an operating segment and includes acquisition transaction expenses, corporate salaries, interest expense and other corporate administrative expenses and intersegment eliminations. ​ The Company’s operating segments also provide transportation and related services for one another. Such services are generally billed at cost, and no profit is earned. Such intersegment revenues and expenses are eliminated in the Company’s consolidated results. Intersegment revenues and expenses for the Flatbed Solutions segment totaled $1.4 million and $2.9 million for the three months ended September 30, 2020 and 2019, respectively, and $4.9 million and $7.5 million for the nine months ended September 30, 2020 and 2019, respectively. Intersegment revenues and expenses for the Specialized Solutions segment totaled $2.4 million and $4.7 million for the three months ended September 30, 2020 and 2019, respectively, and $9.9 million and $8.8 million for the nine months ended September 30, 2020 and 2019, respectively. ​ Certain insurance costs have been allocated to the operating segments beginning January 1, 2020, which were included in the corporate segment in 2019 within the operating income (loss) and income (loss) before income tax line items. Insurance costs included in the corporate segment for the three and nine months ended September 30, 2019 were $0.3 million and $2.5 million, respectively, for the Flatbed Solutions segment and $5.1 million and $11.0 million, respectively, for the Specialized Solutions segment. ​ ​ The following tables reflect certain financial data of the Company’s reportable segments for the three and nine months ended September 30, 2020 and 2019 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Flatbed Specialized ​ ​ ​ ​ ​ Solutions ​ Solutions ​ Corporate/ ​ Consolidated ​ ​ Segment ​ Segment ​ Eliminations ​ Total Three Months Ended September 30, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenue ​ $ 144.5 ​ $ 235.2 ​ $ (3.9) ​ $ 375.8 Company freight ​ ​ 47.1 ​ ​ 129.7 ​ ​ (2.0) ​ ​ 174.8 Owner operator freight ​ ​ 67.2 ​ ​ 37.7 ​ ​ (1.6) ​ ​ 103.3 Brokerage ​ ​ 17.6 ​ ​ 47.8 ​ ​ (0.2) ​ ​ 65.2 Logistics ​ ​ 0.7 ​ ​ 9.1 ​ ​ 0.1 ​ ​ 9.9 Fuel surcharge ​ ​ 11.9 ​ ​ 10.9 ​ ​ (0.2) ​ ​ 22.6 Operating income (loss) ​ ​ 9.3 ​ ​ 31.1 ​ ​ (12.3) ​ ​ 28.1 Depreciation ​ ​ 8.4 ​ ​ 11.8 ​ ​ 0.2 ​ ​ 20.4 Amortization of intangible assets ​ ​ 0.9 ​ ​ 1.0 ​ ​ — ​ ​ 1.9 Restructuring ​ ​ 0.2 ​ ​ 4.9 ​ ​ — ​ ​ 5.1 Non-cash operating lease expense ​ ​ 2.2 ​ ​ (4.7) ​ ​ — ​ ​ (2.5) Interest expense ​ ​ 2.3 ​ ​ 2.9 ​ ​ 5.9 ​ ​ 11.1 Income (loss) before income tax ​ ​ 7.0 ​ ​ 28.8 ​ ​ (18.1) ​ ​ 17.7 Total assets ​ ​ 336.5 ​ ​ 608.1 ​ ​ 231.0 ​ ​ 1,175.6 Capital expenditures ​ ​ 7.2 ​ ​ 11.3 ​ ​ — ​ ​ 18.5 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, 2019 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenue ​ $ 169.8 ​ $ 288.0 ​ $ (7.4) ​ $ 450.4 Company freight ​ ​ 55.2 ​ ​ 155.4 ​ ​ (5.4) ​ ​ 205.2 Owner operator freight ​ ​ 71.1 ​ ​ 49.1 ​ ​ (1.9) ​ ​ 118.3 Brokerage ​ ​ 23.6 ​ ​ 54.5 ​ ​ 0.5 ​ ​ 78.6 Logistics ​ ​ 0.7 ​ ​ 12.9 ​ ​ (0.1) ​ ​ 13.5 Fuel surcharge ​ ​ 19.2 ​ ​ 16.1 ​ ​ (0.5) ​ ​ 34.8 Operating loss ​ ​ (107.9) ​ ​ (187.6) ​ ​ (21.1) ​ ​ (316.6) Depreciation ​ ​ 12.7 ​ ​ 21.1 ​ ​ 0.3 ​ ​ 34.1 Amortization of intangible assets ​ ​ 1.5 ​ ​ 2.7 ​ ​ — ​ ​ 4.2 Impairment ​ ​ 113.2 ​ ​ 193.6 ​ ​ — ​ ​ 306.8 Restructuring ​ ​ 0.9 ​ ​ 3.5 ​ ​ 2.5 ​ ​ 6.9 Non-cash operating lease expense ​ ​ 1.7 ​ ​ 4.6 ​ ​ 0.1 ​ ​ 6.4 Interest expense ​ ​ 2.8 ​ ​ 3.2 ​ ​ 6.8 ​ ​ 12.8 Loss before income tax ​ ​ (110.6) ​ ​ (191.0) ​ ​ (29.5) ​ ​ (331.1) Total assets ​ ​ 376.1 ​ ​ 730.9 ​ ​ 83.1 ​ ​ 1,190.1 Capital expenditures ​ ​ 7.5 ​ ​ 15.0 ​ ​ 0.5 ​ ​ 23.0 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Flatbed Specialized ​ ​ ​ ​ ​ Solutions ​ Solutions ​ Corporate/ ​ Consolidated ​ ​ Segment ​ Segment ​ Eliminations ​ Total Nine Months Ended September 30, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenue ​ $ 436.8 ​ $ 697.2 ​ $ (15.5) ​ $ 1,118.5 Company freight ​ ​ 147.3 ​ ​ 383.5 ​ ​ (8.1) ​ ​ 522.7 Owner operator freight ​ ​ 193.5 ​ ​ 118.7 ​ ​ (5.1) ​ ​ 307.1 Brokerage ​ ​ 52.6 ​ ​ 133.7 ​ ​ (1.5) ​ ​ 184.8 Logistics ​ ​ 2.2 ​ ​ 26.4 ​ ​ 0.2 ​ ​ 28.8 Fuel surcharge ​ ​ 41.2 ​ ​ 34.9 ​ ​ (1.0) ​ ​ 75.1 Operating income (loss) ​ ​ 28.6 ​ ​ 39.1 ​ ​ (35.5) ​ ​ 32.2 Depreciation ​ ​ 25.3 ​ ​ 39.9 ​ ​ 0.7 ​ ​ 65.9 Amortization of intangible assets ​ ​ 2.5 ​ ​ 3.0 ​ ​ — ​ ​ 5.5 Impairment ​ ​ — ​ ​ 13.4 ​ ​ — ​ ​ 13.4 Restructuring ​ ​ 0.3 ​ ​ 8.3 ​ ​ — ​ ​ 8.6 Non-cash operating lease expense ​ ​ 4.3 ​ ​ (4.1) ​ ​ — ​ ​ 0.2 Interest expense ​ ​ 7.2 ​ ​ 8.7 ​ ​ 18.2 ​ ​ 34.1 Income (loss) before income tax ​ ​ 21.7 ​ ​ 30.5 ​ ​ (53.1) ​ ​ (0.9) Capital expenditures ​ ​ 24.2 ​ ​ 39.2 ​ ​ — ​ ​ 63.4 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended September 30, 2019 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenue ​ $ 512.7 ​ $ 838.3 ​ $ (17.0) ​ $ 1,334.0 Company freight ​ ​ 165.3 ​ ​ 463.8 ​ ​ (10.9) ​ ​ 618.2 Owner operator freight ​ ​ 213.1 ​ ​ 142.4 ​ ​ (4.4) ​ ​ 351.1 Brokerage ​ ​ 74.7 ​ ​ 148.3 ​ ​ (0.2) ​ ​ 222.8 Logistics ​ ​ 2.0 ​ ​ 37.1 ​ ​ (0.1) ​ ​ 39.0 Fuel surcharge ​ ​ 57.6 ​ ​ 46.7 ​ ​ (1.4) ​ ​ 102.9 Operating loss ​ ​ (98.5) ​ ​ (168.8) ​ ​ (43.9) ​ ​ (311.2) Depreciation ​ ​ 38.1 ​ ​ 68.5 ​ ​ 0.5 ​ ​ 107.1 Amortization of intangible assets ​ ​ 4.5 ​ ​ 7.9 ​ ​ — ​ ​ 12.4 Impairment ​ ​ 113.2 ​ ​ 193.6 ​ ​ — ​ ​ 306.8 Restructuring ​ ​ 0.9 ​ ​ 3.5 ​ ​ 2.5 ​ ​ 6.9 Non-cash operating lease expense ​ ​ 7.2 ​ ​ 12.2 ​ ​ 0.3 ​ ​ 19.7 Interest expense ​ ​ 8.1 ​ ​ 9.8 ​ ​ 20.3 ​ ​ 38.2 Loss before income tax ​ ​ (106.3) ​ ​ (177.8) ​ ​ (65.3) ​ ​ (349.4) Capital expenditures ​ ​ 38.0 ​ ​ 43.5 ​ ​ 1.5 ​ ​ 83.0 ​

EARNINGS (LOSS) PER SHARE
EARNINGS (LOSS) PER SHARE	NOTE 16 – EARNINGS (LOSS) PER SHARE ​ ASC Topic 260, “Earnings Per Share”, provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. The Company’s outstanding non-vested restricted stock units are participating securities unless there is a net loss attributable to common stockholders. Accordingly, earnings per common share are computed using the two-class method. ​ For the nine months ended September 30, 2020 and the three and nine months ended September 30, 2019, shares of the Company’s 7.625% Series A Convertible Cumulative Preferred Stock (Series A Preferred Stock) and outstanding stock options were not included in the computation of diluted loss per share as their effects were anti-dilutive. Additionally, for the three and nine months ended September 30, 2020 and 2019, there was no dilutive effect from the Merger Agreement earn-out provision found in the Agreement and Plan of Merger, dated December 22, 2016, in which a wholly-owned subsidiary of Hennessy Capital Acquisition Corp.

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2020
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations	Nature of Operations ​ Daseke, Inc.’s (the Company or Daseke) wholly-owned subsidiary Daseke Companies, Inc., was incorporated in December 2008 and began operations on January 1, 2009. Daseke is engaged in full service open-deck trucking that focuses primarily in flatbed truckload and heavy haul transportation of specialized items throughout the United States, Canada and Mexico. The Company also provides logistical planning and warehousing services to customers. The Company is subject to regulation by the Department of Transportation, the Department of Defense, the Department of Energy, and various state regulatory authorities in the United States. The Company is also subject to regulation by the Ministries of Transportation and Communications and various provincial regulatory authorities in Canada.
Basis of Presentation	Basis of Presentation ​ These interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ended December 31, 2020. ​ The consolidated balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements at that date. For additional information, including the Company’s significant accounting policies, refer to the consolidated financial statements and related footnotes for the year ended December 31, 2019 as set forth in the Company’s Annual Report on Form 10-K, filed with the SEC on March 10, 2020. ​ Certain items have been reclassified for presentation purposes to conform to the accounting policies of the consolidated entity. These reclassifications had no material impact on income from operations, net income (loss) and comprehensive income (loss), the balance sheets or statements of cash flows.
Principles of Consolidation	Principles of Consolidation ​ The consolidated financial statements include the accounts of Daseke, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates ​ The preparation of the consolidated financial statements in accordance 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Deferred Financing Fees	Deferred Financing Fees ​ In conjunction with obtaining long-term debt, the Company incurred financing costs which are being amortized using the straight-line method, which approximates the effective interest rate method, over the terms of the obligations. As of September 30, 2020 and December 31, 2019, the balance of deferred finance charges was $8.2 million and $11.4 million, respectively, which is included as a reduction of long-term debt, net of current portion in the consolidated balance sheets. Amortization expense was $1.1 million and $0.9 million for the three months ended September 30, 2020 and 2019, and $3.2 million and $2.4 million for the nine months ended September 30, 2020 and 2019, respectively. Amortization of deferred financing fees is included in interest expense in the consolidated statements of operations and comprehensive income (loss). ​
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets ​ Long-lived assets are reviewed for impairment at the asset group level whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the sum of the expected future undiscounted cash flow is less than the carrying amount of the asset, an impairment is indicated. A loss is then recognized for the difference, if any, between the fair value of the asset (as estimated by management using its best judgment) and the carrying value of the asset. If actual market value is less favorable than that estimated by management, additional write-downs may be required. In the nine months ended September 30, 2020, the Company recognized asset impairments, which are more fully described in Note 3. In the nine months ended September 30, 2019, the Company recognized asset impairments, which are more fully described in Notes 2, 5 and 7.
Fair Value Measurements	Fair Value Measurements ​ The Company follows the accounting guidance for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a framework for measuring fair value and expands disclosures about fair value measurements. The three levels of the fair value framework are as follows: ​ Level 1 Level 2 Level 3 ​ A financial asset or liability’s classification within the framework is determined based on the lowest level of input that is significant to the fair value measurement. ​ Contingent Consideration ​ The contingent consideration liabilities, included in other current liabilities on the consolidated balance sheets, represent future payment obligations for certain EBITDA thresholds related to the Company’s acquisitions over a defined period of time. The fair value of the Company’s contingent consideration liabilities are determined using estimates based on discount rates that reflect the risk involved and the projected EBITDA of the acquired businesses, therefore the liabilities are classified within Level 3 of the fair value framework. The balance of contingent consideration as of September 30, 2020 and December 31, 2019 was $21.2 million and $21.5 million, respectively. The table below is a summary of the changes in the fair value of this liability for the nine months ended September 30, 2020 and 2019 (in millions). The balance as of September 30, 2020 relates to the Aveda earnout discussed in Note 1 and Note 4 of the Company’s 2019 Annual Report on Form 10-K. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ ​ September 30, ​ 2020 2019 Balance at beginning of period ​ $ 21.5 ​ $ 21.9 Change in fair value ​ ​ (0.3) ​ ​ (0.4) Balance at end of period ​ $ 21.2 ​ $ 21.5
Stock-Based Compensation	Stock-Based Compensation ​ Awards of equity instruments issued to employees and directors are accounted for under the fair value method of accounting and recognized in the consolidated statements of operations and comprehensive income (loss). Compensation cost is measured for all stock-based awards at fair value on the date of grant and recognized using the straight-line method over the service period over which the awards are expected to vest. ​ Fair value of all time-vested options as of the date of grant is estimated using the Black-Scholes option valuation model, which was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Since the Company does not have a sufficient history of exercise behavior, expected term is calculated using the assumption that the options will be exercised ratably from the date of vesting to the end of the contractual term for each vesting tranche of awards. The risk-free interest rate is based on the U.S. Treasury yield curve for the period of the expected term of the stock option. For equity-classified awards, expected volatility is calculated using an index of publicly traded peer companies. For liability-classified awards, expected volatility is calculated using split and dividend adjusted closing stock prices over a lookback period commensurate with the remaining term of each award. ​ Fair values of non-vested stock awards (restricted stock units) are equal to the market value of the common stock on the date of the award with compensation costs amortized over the vesting period of the award. ​ Fair values of performance stock units are estimated using the Monte Carlo valuation model in a risk-neutral framework to model future stock price movements based upon highly subjective assumptions, including historical volatility, risk-free rates of return and the stock price simulated over the performance period. The risk-free interest rate is based on the interpolated constant maturity treasury curve for the performance period. Expected volatility is calculated using annualized historical volatility with a lookback period equal to the remaining performance period.
Segment Reporting	Segment Reporting ​ The Company determines its operating segments based on the information utilized by the chief operating decision maker to allocate resources and assess performance. Based on this information, the Company has determined it had 12 operating segments as of September 30, 2020 and 16 operating segments as of September 30, 2019 that are aggregated into two reportable segments: Flatbed Solutions, which delivers its services using primarily flatbed transportation equipment to meet the needs of high-volume, time-sensitive shippers, and Specialized Solutions, which delivers transportation and logistics solutions for super heavy haul, high-value customized and over-dimensional loads, many of which require engineering and customized equipment.
Earnings (loss) Per Share	Earnings (loss) Per Share ​ Basic earnings (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share reflect the potential dilution of earnings per share that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the Company’s income (loss).
Common Stock Purchase Warrants	Common Stock Purchase Warrants ​ The Company accounts for the issuance of common stock purchase warrants in connection with equity offerings in accordance with the provisions of the Accounting Standards Codification (ASC) 815, Derivatives and Hedging (Topic 815). The Company classifies as equity any contract that (i) requires physical settlement or net-share settlement or (ii) gives the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies as assets or liabilities any contract that (i) requires net-cash settlement (including a requirement to net-cash settle the contract if an event occurs and if that event is outside the control of the Company) or (ii) gives the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). See Note 11 for additional details on the common stock purchase warrants. ​ The Company assessed the classification of its common stock purchase warrants and determined that such instruments meet the criteria for equity classification at the time of issuance. ​
Foreign Currency Gains and Losses	Foreign Currency Gains and Losses ​ The functional currency for all operations except Canada is the U.S. dollar. The local currency is the functional currency for the Company’s operations in Canada. For these operations, assets and liabilities are translated at the rates of exchange on the consolidated balance sheet date, while income and expense items are translated at average rates of exchange during the period. The resulting gains or losses arising from the translation of accounts from the functional currency into U.S. dollars are included as a separate component of stockholders’ equity in accumulated other comprehensive income (loss) until a partial or complete liquidation of the Company’s net investment in the foreign operation. ​ From time to time, the Company’s foreign operations may enter into transactions that are denominated in a currency other than their functional currency. These transactions are initially recorded in the functional currency of the operating company based on the applicable exchange rate in effect on the date of the transaction. Monthly, these transactions are remeasured to an equivalent amount of the functional currency based on the applicable exchange rate in effect on the remeasurement date. Any adjustment required to remeasure a transaction to the equivalent amount of functional currency is recorded in the consolidated statements of operations and comprehensive income (loss) of the foreign operating company as a component of foreign exchange gain or loss.
Revenue and Expense Recognition	Revenue and Expense Recognition ​ The Company’s revenue and related costs are recognized when the Company satisfies its performance obligation(s) transferring goods or services to the customer and the customer obtains control of such goods and services. With respect to freight, brokerage, logistics and fuel surcharge revenue, these conditions are met, and the Company recognizes company freight, owner operator freight, brokerage and fuel surcharge revenue, over time, and logistics revenue, as the services are provided. While the Company may enter into master service agreements with its customers, a contract is not established until the customer specifically requests the Company’s services and the Company accepts. The Company evaluates each contract for distinct performance obligations. In the Company’s business, a typical performance obligation is the transportation of a load including any highly interrelated ancillary services. The Company predominantly estimates the standalone selling price of its services based upon observable evidence, market conditions and other relevant inputs. The Company allocates the total transaction price to each distinct performance obligation based upon the relative standalone selling prices. ​ The Company’s customers simultaneously receive and consume the benefits of the Company’s contracts; therefore, revenue is recognized over time. This is a faithful depiction of the satisfaction of the performance obligation, as the customer does not need to re-perform the transportation services the Company has provided to date. ​ Generally, the Company’s customers are billed upon delivery of the freight or monthly and remit payment according to the approved payment terms. ​ Freight Revenue ​ Freight revenue is generated by hauling customer freight using company owned equipment (company freight) and owner-operator equipment (owner-operator freight). Freight revenue is the product of the number of revenue-generating miles driven and the rate per mile received from customers plus accessorial charges, such as loading and unloading freight, cargo protection, fees for detained equipment or fees for route planning and supervision. ​ Brokerage Revenue The Company regularly engages third-party capacity providers to haul loads. The Company is primarily responsible for fulfilling the promise to provide load transportation services, and has discretion in setting prices, along with the risk to fulfill the contract to the customer. Based upon this evaluation, the Company has determined that it is the principal and therefore, records gross revenues and expenses for brokerage services. ​ Logistics Revenue ​ Logistics revenue is generated from a range of services, including value-added warehousing, loading and unloading, vehicle maintenance and repair, preparation and packaging, fuel management, and other fleet management solutions. The Company recognizes logistics revenue as services are completed. ​ Fuel Surcharge ​ Fuel surcharge revenue compensates the Company for fuel costs above a certain cost per gallon base. Generally, the Company receives fuel surcharges on the miles for which it is compensated by customers. ​ Practical expedients ​ The Company has designated the following preference and practical expedients: ​ ● To not disclose remaining performance obligations when the expected performance obligation duration is one year or less. The vast majority of the Company’s services transfer control within a month of the inception of the contract with select specialized loads taking several months to allow for increased planning and permitting. ​ ● Recognize the incremental costs of obtaining or fulfilling a contract as an expense when incurred, as the amortization period of a potential asset would be recognized in one year or less. ​ ● Exclude taxes collected on behalf of government authorities from the Company’s measurement of transaction prices. Tax amounts are not included within net income (loss) or cost of sales.
Lease Accounting	Lease Accounting ​ Lessee ​ The Company has capitalized operating and finance leases for various real estate including corporate offices, trucking facilities and terminals, warehouses, and tractor parking as well as various types of equipment including tractors, trailers, forklifts, and office equipment. New real estate lease agreements will typically have initial terms have terms ​ Some of the Company’s leases include one or more options to renew, with renewals that can extend the lease from ​ The Company determines whether an arrangement is classified as a lease at inception. The right-of-use assets and lease liabilities relating to operating leases are included in right-of-use assets, other current liabilities, and other long-term liabilities on the Company's consolidated balance sheets. The right-of-use assets and lease liabilities relating to finance leases are included in other long-term assets, current portion of long-term debt, and long-term debt, net of current portion on the Company's consolidated balance sheets. The Company's right-of-use assets represent its right to use the underlying assets for the lease term and the Company's right-of-use liabilities represent its obligation to make lease payments arising from the leases. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company's capitalized operating lease agreements generally do not provide an implicit rate.
