NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1.  Basis of Presentation and New Accounting Pronouncements

Heartland Express, Inc. (the “Company,” “we,” “us,” or “our”), is a holding company incorporated in Nevada, which owns all of the stock of Heartland Express Inc. of Iowa, Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. Gordon Trucking, Inc. ("GTI") was merged into Heartland Express Inc. of Iowa effective July 1, 2016. We, and our subsidiaries, operate as one segment. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load) with corporate headquarters in North Liberty, Iowa. We primarily provide nationwide asset-based dry van truckload service for major shippers from Washington to Florida and New England to California.

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned.  All material intercompany items and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes to the financial statements required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all normal, recurring adjustments considered necessary for a fair presentation have been included. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on February 28, 2017. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods. There were no changes to the Company's significant accounting policies during the six month period ended June 30, 2017, except as noted below in regards to the accounting for employee share based payments.

In May 2017, the Financial Accounting Standards Boards (FASB) issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," to provide clarity and reduce diversity and complexity of applying the accounting guidance in Topic 718 to a change in the terms or conditions of a share-based payment award. An entity should account for the effects of a modification unless certain criteria are met. The provisions of this update are effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements and we expect to adopt this standard prospectively for interim and annual periods beginning January 1, 2018.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” which continues to require an entity to review indicators for impairment, perform qualitative assessments, and analyze the fair value of a reporting unit as compared to the carrying value of goodwill for potential impairment but eliminates or replaces additional tests and assessments within the prior guidance. The provisions of this update are effective for fiscal years beginning after December 15, 2019, with early adoption permitted for impairment measurement tests occurring after January 1, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we are unable to predict whether the amount of restricted cash to be included will be material to our statement of cash flows at this time, but we fully intend to include and explain the change in restricted cash upon adoption of the standard.

Further ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our consolidated cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". This update requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Based

7

on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In March, 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". This update seeks to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. This update was effective for the Company beginning January 1, 2017 and was adopted accordingly, including forfeitures being recorded as incurred, during the first quarter ended March 31, 2017 and for future periods. The adoption did not have a material impact on our financial statements and prior periods presented have not been adjusted.

In February 2016, the FASB issued ASU 2016-02, "Leases". This update seeks to increase the transparency and comparability among entities by requiring public entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. To satisfy the standard’s objective, a lessee will recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a lease liability for the obligation to make lease payments. Both the right-of-use asset and lease liability will initially be measured at the present value of the lease payments, with subsequent measurement dependent on the classification of the lease as either a finance or an operating lease. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term.

In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for public companies for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. Based on our initial assessment, we believed the impact of adoption of the standard would not have a material impact on our financial statements. We have not yet performed an updated assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington ("IDC"). We expect to complete an updated combined assessment and select a transition method by January 1, 2019, our date of transition.

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. We have been closely monitoring FASB activity related to the new standard and are evaluating the effect that the new guidance will have on our consolidated financial statements and related disclosures. We have performed an analysis of our revenue transactions across the operations for our legacy operations as they existed through June 30, 2017, and based on that we believed that our adoption would not have a material impact on our operating revenue or operating income as a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We have not yet performed our assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of IDC. We expect to complete an updated combined assessment and select a transition method by January 1, 2018, our date of transition.

Note 2.  Use of Estimates

The preparation of the consolidated 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. There were no significant changes in estimates and assumptions used by management related to our critical accounting policies during the three and six months ended June 30, 2017.

Note 3. Segment Information

We provide truckload services across the United States (U.S.) and parts of Canada. These truckload services are primarily asset-based transportation services in the dry van truckload market, and we also offer truckload temperature-controlled transportation services and non-asset based brokerage services, neither of which are significant to our operations. We exited our non-asset-based freight brokerage business in the first quarter of 2017. Our Chief Operating Decision Maker oversees and manages all of our transportation services, on a combined basis, including previously acquired entities. As a result of the foregoing, we have determined that we have one segment, consistent with the authoritative accounting guidance on disclosures about segments of an enterprise and related information.

Note 4. Cash and Cash Equivalents

Cash equivalents are short-term, highly liquid investments with insignificant interest rate risk and original maturities of three months or less at acquisition. At June 30, 2017, restricted and designated cash and investments totaled $24.4 million, of which $12.9 million was included in other current assets and $11.5 million was included in other non-current assets in the consolidated balance sheet. Restricted and designated cash and investments totaled $21.7 million at December 31, 2016, of which $9.3 million was included in other current assets and $12.4 million was included in other non-current assets in the consolidated balance sheet.  The restricted funds represent deposits required by state agencies for self-insurance purposes and designated funds that are earmarked for a specific purpose and not for general business use.

Note 5. Prepaid Tires, Property, Equipment, and Depreciation

Property and equipment are reported at cost, net of accumulated depreciation. Maintenance and repairs are charged to operations as incurred.  New tires are capitalized separately from revenue equipment and are reported separately as “Prepaid tires” in the consolidated balance sheets and amortized over two years.  Depreciation for financial statement purposes is computed by the straight-line method for all assets other than tractors.  We recognize depreciation expense on tractors using the 125% declining balance method. New tractors are depreciated to salvage values of $15,000 while new trailers are depreciated to salvage values of $4,000.

Note 6. Other Intangibles, Net and Goodwill

All intangible assets determined to have finite lives are amortized over their estimated useful lives. The useful life of an intangible asset is the period over which the asset is expected to contribute directly or indirectly to future cash flows. There was no change in the gross amount of identifiable intangible assets during the three and six months ended June 30, 2017. Amortization expense of $0.5 million, $1.0 million and $0.5 million, $1.0 million for the three and six months ended June 30, 2017 and 2016, respectively, was included in depreciation and amortization in the consolidated statements of comprehensive income. Intangible assets subject to amortization consisted of the following at June 30, 2017:

	Amortization period (years)	Gross Amount		Accumulated Amortization		Net intangible assets
		(in thousands)
Customer relationships	20	$	7,600	$	1,377	$	6,223
Tradename	6	7,400		4,471		2,929
Covenants not to compete	10	3,100		1,124		1,976
		$	18,100	$	6,972	$	11,128

There were no changes in the carrying amount of goodwill during the three and six months ended June 30, 2017.

Note 7. Earnings per Share

Basic earnings per share is based upon the weighted average common shares outstanding during each year.  Diluted earnings per share is based on the basic weighted earnings per share with additional weighted common shares for common stock equivalents. During the three and six months ended June 30, 2017 and June 30, 2016, we had outstanding restricted shares of common stock to certain of our employees under the Company's 2011 Restricted Stock Award Plan (the "Plan"). A reconciliation of the numerator (net income) and denominator (weighted average number of shares outstanding of the basic and diluted earnings per share ("EPS")) for the three and six months ended June 30, 2017 and June 30, 2016 is as follows (in thousands, except per share data):

Note 8. Equity

We have a stock repurchase program with 3.3 million shares remaining authorized for repurchase as of June 30, 2017. There were no shares repurchased in the open market during the three and six months ended June 30, 2017 and there were zero and 0.9 million shares repurchased during the same periods in 2016. Repurchases are expected to continue from time to time, as determined by market conditions, cash flow requirements, securities law limitations, and other factors, until the number of shares authorized have been repurchased, or until the authorization is terminated. The share repurchase authorization is discretionary and has no expiration date.

During the three and six months ended June 30, 2017 and 2016, our Board of Directors declared regular quarterly dividends totaling $1.7 million, $3.3 million and $1.7 million, $3.3 million , respectively.  Future payment of cash dividends and the amount of such dividends will depend upon our financial conditions, our results of operations, our cash requirements, our tax treatment, and certain corporate law requirements, as well as factors deemed relevant by our Board of Directors.

Note 9. Stock-Based Compensation

In July 2011, a Special Meeting of Stockholders of Heartland Express, Inc. was held, at which meeting the approval of the Plan was ratified. The Plan is administered by the Compensation Committee of our Board of Directors. Per the terms of the awards, employees receiving awards will have all of the rights of a stockholder with respect to the unvested restricted shares including, but not limited to, the right to receive such cash dividends, if any, as may be declared on such shares from time to time and the right to vote such shares at any meeting of our stockholders.

The Plan made available up to 0.9 million shares for the purpose of making restricted stock grants to our eligible officers and employees. Shares granted in 2013 through 2017 have various vesting terms that range from immediate to four years from the date of grant. Once vested, there are no other restrictions on the awards. Compensation expense associated with these awards is based on the market value of our stock on the grant date. Our market closing price ranged between $13.86 and $18.18 on the various grant dates for the shares granted in 2013. The Company's market close price ranged between $21.72 and $27.47 on the various grant dates during 2014, ranged between $19.93 and $27.29 on the various grant dates during 2015, and ranged between $17.06 and $18.78 on the various grant dates during 2016. The Company's market close price was $20.53 for the grant date during the six months ended June 30, 2017. There were no significant assumptions made in determining the fair value. Compensation expense associated with restricted stock awards is included in salaries, wages and benefits in the consolidated statements of comprehensive income. Compensation expense associated with restricted stock awards was $0.2 million and $0.3 million, for the three and six ended June 30, 2017. Compensation expense associated with restricted stock awards was $0.3 million and $1.0 million for the three and six ended June 30, 2016, respectively. Unrecognized compensation expense was $0.2 million at June 30, 2017 which will be recognized over a weighted average period of 1.1 years.

The following tables summarize our restricted stock award activity for the three and six months ended June 30, 2017 and 2016.

Note 10.  Long-Term Debt

In November 2013, we entered into a Credit Agreement with Wells Fargo Bank, National Association, (the “Bank”). Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit which may be used for future working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $175.0 million on November 1, 2016 through October 31, 2018.

The Credit Agreement is unsecured, with a negative pledge against all assets of our consolidated group, except for debt associated with permitted acquisitions, new purchase-money debt and capital lease obligations as described in the Credit Agreement. The Credit Agreement matures on October 31, 2018. The Borrower has the ability to terminate the commitment at any time at no additional cost to the Borrower. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0.0%, floating. There is a commitment fee on the unused portion of the Revolver at 0.0625%, due monthly.

The Credit Agreement contains customary financial covenants including, but not limited to, (i) a maximum adjusted leverage ratio of 2:1, measured quarterly on a trailing twelve month basis, (ii) a minimum net income requirement of $1.00, measured quarterly on a trailing twelve month basis, (iii) a minimum tangible net worth of $175.0 million requirement, measured quarterly, and (iv) limitations on other indebtedness and liens. The Credit Agreement also includes customary events of default, conditions, representations and warranties, and indemnification provisions. We were in compliance with the respective financial covenants at June 30, 2017.

We had no outstanding long-term debt at June 30, 2017 or December 31, 2016. Outstanding letters of credit associated with the revolving line of credit at June 30, 2017 were $3.7 million. As of June 30, 2017, the line of credit available for future borrowing was $171.3 million.

Note 11.  Income Taxes

We use the asset and liability method of accounting for income taxes.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when temporary differences reverse. The effe

12

ct of a change in tax rates on deferred taxes is recognized in the period that the change is enacted. A valuation allowance is recorded to reduce the Company's deferred tax assets to the amount that is more likely than not to be realized. We had no recorded valuation allowance at June 30, 2017 and December 31, 2016. Our effective tax rate was 32.8% and 33.5% for the three months ended and 30.8% and 31.6% for the six months ended June 30, 2017 and 2016, respectively.  

We recognize the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  We record interest and penalties related to unrecognized tax benefits in income tax expense.

At June 30, 2017 and December 31, 2016, we had a total of $5.9 million and $8.8 million in gross unrecognized tax benefits, respectively included in long-term income taxes payable in the consolidated balance sheet.  Of this amount, $4.0 million and $5.7 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of June 30, 2017 and December 31, 2016.  The net decrease in unrecognized tax benefits was $1.2 million and $1.3 million during the three months ended June 30, 2017 and 2016, respectively.  The net decrease in unrecognized tax benefits was $2.9 million and $1.7 million during the six months ended June 30, 2017 and 2016, respectively. The net decrease during the three and six month periods of 2017 and 2016 was mainly due to the expiration of certain statues of limitation net of additions and settlements with respective states. This had the effect of decreasing the effective state tax rate during these respective periods. The total net amount of accrued interest and penalties for such unrecognized tax benefits was $1.9 million and $3.2 million at June 30, 2017 and December 31, 2016 and is included in long-term income taxes payable in the consolidated balance sheets.  Income tax expense is increased each period for the accrual of interest on outstanding positions and penalties when the uncertain tax position is initially recorded. Income tax expense is reduced in periods by the amount of accrued interest and penalties associated with reversed uncertain tax positions due to lapse of applicable statute of limitations, when applicable or when a position is settled.

Net interest and penalties included in income tax expense for the three month period ended June 30, 2017 and 2016 was a net benefit of approximately $0.5 million and $0.9 million, respectively. Net interest and penalties included in income tax expense for the six month period ended June 30, 2017 and 2016 was a net benefit of approximately $1.3 million and $1.6 million, respectively. Income tax expense decreased during the three and six months ended June 30, 2017 and 2016 due to reductions for the expiration of applicable statute of limitations. These unrecognized tax benefits relate to risks associated with state income tax filing positions for our corporate subsidiaries.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2017
	(in thousands)
Balance at January 1, 2017	$	8,751
Additions based on tax positions related to current year	145
Additions for tax positions of prior years	—
Reductions for tax positions of prior years	(415		)
Reductions due to lapse of applicable statute of limitations	(2,602		)
Settlements	(17		)
Balance at June 30, 2017	$	5,862

A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. We do not have any outstanding litigation related to tax matters.  At this time, management’s best estimate of the reasonably possible change in the amount of gross unrecognized tax benefits to be a decrease of approximately $1.5 million to a decrease of $2.5 million during the next twelve months mainly due to the expiration of certain statute of limitations, net of additions.  The federal statute of limitations remains open for the years 2014 and forward. Tax years 2007 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.

Note 12.  Operating Leases

There were no leases for revenue equipment for the three and six months ended June 30, 2017. During 2016, we leased certain revenue equipment of which the majority of these leases were with a commercial tractor dealership, which is partially owned by one of our board members. Rent expense for these leases was $0.3 million and $0.8 million (including related-party rental payments totaling $0.3 million and $0.8 million), for the three and six months ended June 30, 2016. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income. The leases were terminated in June 2016.

We lease certain terminal facilities under operating leases. A portion of these leases are with limited liability companies, whose members include one of our board members and a commercial tractor dealership whose owners include one of our board members. The related-party rental payments were entered into as a result of a previous acquisition. Rent expenses for terminal facilities were $0.5 million and $1.0 million (including related-party rental payments totaling $0.4 million and $0.8 million), for the three and six months ended June 30, 2017. Rent expenses for terminal facilities were $0.5 million and $1.1 million (including related-party rental payments totaling $0.5 million and $0.9 million), for the three and six months ended June 30, 2016. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire from 2017 through 2018 and contain purchase options and options to renew, except the Pacific, Washington location. We have renewal options and a right of first refusal on the sale of the Pacific, Washington location property. We are responsible for all taxes, insurance, and utilities related to the terminal leases. See Note 13 for additional information regarding related party transactions.

Note 13. Related Party

We lease certain terminal facilities for operations under operating leases from certain limited liability companies, whose members include one of our board members and a commercial tractor dealership whose owners include one of our board members. The terminal facility leases have initial five year terms, purchase options and options to renew excluding the lease for Pacific, Washington location. The Pacific, Washington location contains lease renewal options and a right of first refusal on any sale of the property.

We have sold trailers to the commercial tractor dealership noted above. We also had operating leases for certain revenue equipment with the commercial tractor dealership and have purchased parts and services from the same commercial tractor dealership. We owed the commercial tractor dealership $0.1 million and $0.1 million, included in accounts payable and accrued liabilities in the consolidated balance sheets at June 30, 2017 and December 31, 2016, respectively.

The related payments (receipts) with related parties for the three and six months ended June 30, 2017 and 2016 (in thousands) were as follows:

Note 14.  Commitments and Contingencies

We are a party to ordinary, routine litigation and administrative proceedings incidental to its business. In the opinion of management, our potential exposure under pending legal proceedings is adequately provided for in the accompanying consolidated financial statements.  

The total estimated purchase commitments for tractors, net of tractor sale commitments, and trailer equipment as of June 30, 2017 was $63.6 million.

Note 15.  Subsequent Events

On July 6, 2017, we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington ("IDC") from Saltchuk Resources, Inc. ("Saltchuk"). The acquisition allows us to add high quality drivers, experienced personnel, and a strong customer base to our operations. We gained additional traffic density in the West, and our stronger Eastern network will improve service for IDC's customers in the East. We have not completed the initial accounting for the acquisition and we are still collecting certain pre-acquisition financial information to complete our supplemental proforma information. The transaction enterprise value was approximately $113 million and includes approximately $94 million in cash for the equity, $23 million in assumed debt, and $4 million in acquired cash.

Overview

We are a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We concentrate primarily on short-to-medium haul, asset-based dry van truckload services in regional markets near our terminals, where the average trip is approximately one day. We focus on providing quality service to targeted customers with a high density of freight in our regional operating areas. We also offer temperature-controlled truckload services, which are not significant to our operations. We exited our non-asset-based freight brokerage business in the first quarter of 2017.

We generally earn revenue based on the number of miles per load delivered and the revenue per mile paid.  We believe the keys to success are maintaining high levels of customer service and safety which are predicated on the availability of experienced drivers and late-model equipment. We achieve operating efficiencies and cost controls through equipment utilization, which is optimized by a common information system platform, a fleet of late model equipment, industry-leading driver to non-driver employee ratio, and effective management of fixed and variable operating costs. We believe that our service standards, safety record, and equipment accessibility have made us a core carrier to many of our customers, as well as allowed us to build solid, long-term relationships with customers and brand ourselves as an industry leader for on-time service.  

Competition for drivers, which has historically been intense, has recently escalated due to the decreasing numbers of qualified drivers in the industry, and we have experienced increased difficulties attracting and retaining qualified drivers. We continue to explore new strategies to attract and retain qualified drivers. We hire the majority of our drivers with at least six to nine months of over-the-road experience and safe driving records. In order to attract and retain experienced drivers who understand the importance of customer service, we have sought to solidify our position as an industry leader in driver compensation in our operating markets. Our comprehensive driver compensation program rewards drivers for years of service and safe operating mileage benchmarks, which are critical to our operational and financial performance. Our driver pay package includes future pay increases based on years of continued service with us, increased rates for accident-free miles of operation, and detention pay to assist drivers with offsetting unproductive detention time. We believe that our driver compensation package is consistently among the best in the industry. We are committed to investing in our drivers and compensating them for safety as both are key to our operational and financial performance.

Containment of fuel cost continues to be one of management's top priorities. Average DOE diesel fuel prices for the three months ended June 30, 2017 and 2016 were $2.55 and $2.32, respectively. The average price per gallon in 2017, through July 31, 2017,

16

was $2.53. Although the average price per gallon in 2016 was the lowest it has been since 2009, fuel prices rose later in 2016 but have remained relatively flat during the first six months of 2017. We cannot predict what fuel prices will be throughout 2017. We are not able to pass through all fuel price increases through fuel surcharge agreements with customers due to tractor idling time, along with empty and out-of-route miles. Therefore, our operating income is negatively impacted with increased net fuel costs (fuel expense less fuel surcharge revenue) in a rising fuel environment and is positively impacted in a declining fuel environment. We continue to manage and implement fuel initiative strategies that we believe will effectively manage fuel costs.  These initiatives include strategic fueling of our trucks, whether it be terminal fuel or over-the-road fuel, reducing tractor idle time, controlling out-of-route miles, controlling empty miles, utilizing on-board power units to minimize idling, educating drivers to save energy, trailer skirting, and increasing fuel economy through the purchase of newer, more fuel-efficient tractors. At June 30, 2017, 99% of our over-the-road sleeper berth tractor fleet was equipped with idle management controls. At June 30, 2017, the Company’s tractor fleet had an average age of 1.9 years and the Company's trailer fleet had an average age of 4.3 years.

We continue to focus on providing quality service to targeted customers with a high density of freight in our regional operating areas. In addition to the development of our regional operating areas, we have made six acquisitions since 1987 and just announced our most recent seventh acquisition on July 6, 2017 where we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington.  Future growth depends upon several factors including the level of economic growth and the related customer demand, the available capacity in the trucking industry, our ability to identify and consummate future acquisitions, our ability to integrate operations of acquired companies to realize efficiencies, and our ability to attract and retain experienced drivers that meet our hiring standards.

We ended the first six months of 2017 with operating revenues of $259.5 million, including fuel surcharges, net income of $28.7 million, and basic net income per share of $0.34 on basic weighted average outstanding shares of 83.3 million compared to operating revenues of $323.6 million, including fuel surcharges, net income of $30.7 million, and basic net income per share of $0.37 on basic weighted average shares of 83.3 million in the first six months of 2016. We posted an 84.3% operating ratio (operating expenses as a percentage of operating revenues) for the six months ended June 30, 2017 compared to 86.2% for the same period of 2016. We posted an 82.3% non-GAAP adjusted operating ratio⁽¹⁾ (operating expenses as a percentage of operating revenues, net of fuel surcharge) for the six months ended June 30, 2017 compared to 84.8% for the same period of 2016. We had total assets of $751.1 million at June 30, 2017. We achieved a return on assets of 7.3% and a return on equity of 10.6% over the immediate past four quarters ended June 30, 2017, compared to 8.5% and 13.1%, respectively, for the immediate past four quarters ended June 30, 2016.  

Our cash flow from operating activities for the six months ended June 30, 2017 of $50.8 million was 19.6% of operating revenues, compared to $77.9 million and 24.1% in the same period of 2016.  During 2017, we used $4.6 million in net investing cash flows, which was the net result of net cash received from revenue equipment sales and cash used for revenue equipment purchases. We used $3.5 million in financing activities mostly related to the payment of dividends. As a result, our cash and cash equivalents increased $42.8 million during the six months ended June 30, 2017.  We ended the second quarter of 2017 with cash and cash equivalents of $171.3 million.

Three Months Ended June 30, 2017 Compared With the Three Months Ended June 30, 2016

Operating revenue decreased $31.2 million (19.4%), to $129.6 million for the three months ended June 30, 2017 from $160.8 million for the three months ended June 30, 2016.  The decrease in revenue was the result of the combined effect of a decrease in trucking and other revenues of $30.6 million (21.0%) and a $0.6 million (3.9%) decrease in fuel surcharge revenue from $15.3 million in 2016 to $14.7 million in 2017. Operating revenues (the total of trucking and fuel surcharge revenue) are primarily earned based on loaded miles driven in providing truckload transportation services. The number of loaded miles is affected by general freight supply and demand trends and the number of revenue earning equipment vehicles (tractors). The number of revenue earning equipment vehicles (tractors) is directly affected by the number of available company drivers and independent contractors providing capacity to us. Our operating revenues are reviewed regularly on a combined basis across the United States due to the similar nature of our service offerings and related similar base pricing structure. The net trucking revenue decrease was mainly the result of a decrease in loaded miles mainly due to a decrease in drivers during the three months ended June 30, 2017 as compared to 2016. We exited our non-asset based brokerage business in the first quarter of 2017, and expect non-asset based brokerage services revenue to be less than 1% of gross revenues for 2017.

Fuel surcharge revenues represent fuel costs passed on to customers based on customer specific fuel surcharge recovery rates and billed loaded miles. Fuel surcharge revenues decreased primarily as a result of the net effect of a decrease in loaded miles driven partially offset by a 9.7% increase in the average Department of Energy ("DOE") diesel fuel prices during the three months ended June 30, 2017 compared to June 30, 2016, as reported by the DOE.

Salaries, wages, and benefits decreased $12.9 million (20.9%), to $48.6 million for the three months ended June 30, 2017 from $61.5 million in the 2016 period.  Salaries, wages and benefits decreased period over period due to decreases in driver and non-driver wages and lower health insurance and workers compensation costs as compared to the same period in 2016. Reduction in expense period over period is due mainly to less miles driven and lower overall non-driving headcount.

Rent and purchased transportation decreased $4.4 million (70.6%), to $1.8 million for the three months ended June 30, 2017 from $6.2 million in the comparable period of 2016.  The decrease was attributable to amounts paid to third party carriers on brokered loads (decreased $3.1 million), amounts paid to independent contractors (decreased $0.8 million), and amounts paid for operating leases of terminal locations and revenue equipment amounts (decreased $0.1 million). The decrease in amounts paid were due to

19

a decrease in loads brokered with third party carriers, a decrease in miles driven by independent contractors, and a reduction in leased revenue equipment units during the 2017 period as compared to 2016. During the three months ended June 30, 2017, independent contractors accounted for 1.5% of the total fleet miles compared to approximately 2.3% for the same period of 2016.

Fuel decreased $3.1 million (12.7%), to $21.3 million for the three months ended June 30, 2017 from $24.4 million for the same period of 2016. The decrease was due to the net result of a decrease in miles driven and improvements in fuel economy, offset by a (9.7%) increase in the average diesel price per gallon as reported by the DOE. Fuel cost per mile, net of fuel surcharge revenues, decreased 11.3% in the 2017 period compared to the same period of 2016, due mainly to decreased fuel surcharge revenues offset partially by an increase in average diesel fuel costs.

Depreciation decreased $3.2 million (12.5%), to $22.6 million during the three months ended June 30, 2017 from $25.8 million in the same period of 2016.  The decrease is mainly attributable to a decrease in the number of units being depreciated and lower average depreciation expense per revenue equipment unit. Tractor depreciation decreased $3.0 million, on a 12.6% decrease in the number of tractor units depreciated and a 4.1% lower depreciation recognized per unit during the three months ended June 30, 2017 compared to the 2016 period. Compared to the same period in 2016, trailer and other depreciation decreased $0.3 million on a 8.4% decrease in the number of trailer units depreciated partially offset by 4.9% higher depreciation recognized per unit during the three months ended June 30, 2017.

Operating and maintenance expense was flat at $7.0 million during the three months ended June 30, 2017 and 2016. The decrease is mainly due the offsetting effects of an increase in tires expense related to the purchase and sale transactions for revenue equipment offset by a decrease in expense related to the number of revenue equipment units in the fleet and a decrease in miles driven.

Operating taxes and licenses expense decreased $0.8 million (20.3%), to $3.1 million during the three months ended June 30, 2017 from $3.9 million in 2016, due to a decrease in the number of revenue equipment units (tractors and trailers) being licensed and reduced fuel taxes due to less miles driven.

Insurance and claims expense decreased $1.4 million (28.1%), to $3.6 million for the three months ended June 30, 2017 from $5.0 million in 2016, due to decreased severity and frequency of claims as compared to the prior year mainly due to a reduction in miles driven.

Other operating expenses decreased $0.4 million (6.3%), to $5.5 million, during the three months ended June 30, 2017 from $5.9 million in 2016 due to lower variable spend related to fewer miles driven partially offset by an increase in professional services related to the acquisition of IDC.

Gains on the disposal of property and equipment increased $1.8 million (39.6%), to $6.3 million during the three months ended June 30, 2017 from $4.5 million in the same period of 2016.  The increase resulted from the net effect of an increase in gains on sales of trailer equipment of $3.6 million offset by a decrease in gains on sale of tractor and other equipment of $1.8 million. The increase in gains on trailer sales was due to a 367% increase in the number of units sold and a significant increase in gain per unit. The decrease in gains on tractor sales was due to a 6% decrease in the number of units sold along with a gain per unit decrease of 40%.

Our effective tax rate declined to 32.8% from 33.5% for the three months ended June 30, 2017 and 2016, respectively.  

As a result of the foregoing, our operating ratio (operating expenses as a percentage of operating revenue) was 83.6% during the three months ended June 30, 2017, compared to 84.8% during the three months ended June 30, 2016.  Our non-GAAP adjusted operating ratio⁽¹⁾ (operating expenses as a percentage of operating revenues, net of fuel surcharge) was 81.4% during the three months ended June 30, 2017, compared to 83.2% during the three months ended June 30, 2016. Net income decreased $1.8 million (10.7%), to $14.6 million for the three months ended June 30, 2017, from $16.4 million during the same period in 2016 as a result of the net effects discussed above.

Six Months Ended June 30, 2017 Compared With the Six Months Ended June 30, 2016

Operating revenue decreased $64.1 million (19.8%), to $259.5 million for the six months ended June 30, 2017 from $323.6 million for the six months ended June 30, 2016.  The decrease in revenue was the result of the combined effect of a decrease in trucking and other revenues of $65.2 million (22.1%) partially offset by a $1.2 million (4.2%) increase in fuel surcharge revenue from $28.4 million in 2016 to $29.6 million in 2017. Operating revenues (the total of trucking and fuel surcharge revenue) are primarily earned based on loaded miles driven in providing truckload transportation services. The number of loaded miles is affected by general freight supply and demand trends and the number of revenue earning equipment vehicles (tractors). The number of revenue earning equipment vehicles (tractors) is directly affected by the number of available company drivers and independent contractors

20

providing capacity to us. Our operating revenues are reviewed regularly on a combined basis across the United States due to the similar nature of our service offerings and related similar base pricing structure. The net trucking revenue decrease was the result of a decrease in loaded miles due to a decrease in drivers and slowing freight demand in the 2017 period compared to the 2016 period, partially offset by an increase in the rate per loaded mile and an increase is fuel surcharge revenue as compared to the six months ended June 30, 2017.

Fuel surcharge revenues represent fuel costs passed on to customers based on customer specific fuel surcharge recovery rates and billed loaded miles. Fuel surcharge revenues increased primarily as a result of a 15.2% increase in the average Department of Energy ("DOE") diesel fuel prices during the six months ended June 30, 2017 compared to June 30, 2016, as reported by the DOE, offset by a decrease in loaded miles during the same period.

Salaries, wages, and benefits decreased $29.4 million (23.1%), to $97.6 million for the six months ended June 30, 2017 from $127.0 million in the 2016 period.  Salaries, wages and benefits decreased period over period due mainly to decreases in driver and non-driver wages and lower health insurance and workers compensation costs as compared to the same period in 2016. Reduction in expense period over period is due mainly to less miles driven and lower overall non-driving headcount.

Rent and purchased transportation decreased $8.2 million (63.7%), to $4.7 million for the six months ended June 30, 2017 from $12.9 million in the comparable period of 2016.  The decrease was attributable to amounts paid to third party carriers on brokered loads (decreased $5.4 million), amounts paid to independent contractors (decreased $1.6 million), and amounts paid for operating leases of terminal locations and revenue equipment (decreased $1.1 million). The decrease in amounts paid were due to a decrease in loads brokered with third party carriers, a decrease in miles driven by independent contractors, and a reduction in leased revenue equipment units during the 2017 period as compared to 2016. During the six months ended June 30, 2017, independent contractors accounted for 1.6% of the total fleet miles compared to approximately 2.4% for the same period of 2016.

Fuel decreased $1.6 million (3.5%), to $44.0 million for the six months ended June 30, 2017 from $45.6 million for the same period of 2016. The decrease was primarily the result of the net effect of lower miles driven partially offset by a 15.2% increase in the average diesel price per gallon as reported by the DOE and lower miles driven. Fuel cost per mile, net of fuel surcharge revenues, increased 3.5% in the 2017 period compared to the same period of 2016, due mainly to fuel surcharge revenues increasing at a decreased rate (4.2%), as compared to the increase in overall fuel cost.

Depreciation and amortization decreased $6.0 million (11.7%), to $45.5 million during the six months ended June 30, 2017 from $51.6 million in the same period of 2016.  The decrease is mainly attributable to a decrease in the number of units being depreciated, partially offset by lower average depreciation expense per revenue equipment unit. Tractor depreciation decreased $5.3 million, on a 14.6% decrease in the number of tractor units depreciated and 4.4% lower depreciation recognized per unit during the six months ended June 30, 2017 compared to the 2016 period. Compared to the same period in 2016, trailer and other depreciation decreased $0.7 million on a 5.2% decrease in the number of trailer units depreciated during the six months ended June 30, 2017, partially offset by 1.0% higher depreciation recognized per unit.

Operating and maintenance expense decreased $0.8 million (5.7%), to $12.8 million during the six months ended June 30, 2017 from $13.6 million in the same period of 2016. The decrease is mainly due to a decrease in the number of revenue equipment units in the fleet, a decrease in miles driven, and the age of our fleet of revenue equipment.

Operating taxes and licenses expense decreased $1.4 million (17.9%), to $6.4 million during the six months ended June 30, 2017 from $7.8 million in 2016, due to a decrease in the number of revenue equipment units (tractors and trailers) being licensed and reduced fuel taxes due to less miles driven.

Insurance and claims expense decreased $5.7 million (43.7%), to $7.4 million during the six months ended June 30, 2017 from $13.1 million in 2016, due to decreased severity and frequency of claims in 2017 mainly due to a reduction in miles driven.

Other operating expenses decreased $0.2 million (1.9%), to $10.6 million, during the six months ended June 30, 2017 from $10.8 million in 2016, due to lower variable spend related to fewer miles driven partially offset by an increase in professional services related to the acquisition of IDC.

Gains on the disposal of property and equipment increased $6.6 million (113.4%), to $12.4 million during the six months ended June 30, 2017 from $5.8 million in the same period of 2016.  The increase resulted from the net effect of an increase in gains on sales of trailer equipment of $8.1 million, a decrease in gains on tractor equipment sales of $0.4 million, and a decrease in gains on sale of other property of $0.1 million. The increase in gains on trailer sales was due to selling 341% more trailers during 2017, and a significant increase in gains per unit. The decrease in gains on tractor sales was due to a decrease in the amount of gains

21

per unit of 31% partially offset by an increase in the number of units sold. We currently anticipate tractor and trailer equipment sale activity during 2017 to generate total estimated gains of approximately $24 to $28 million.

The Company’s effective tax rate was 30.8% and 31.6% for the six months ended June 30, 2017 and 2016, respectively.  

As a result of the foregoing, the Company’s operating ratio (operating expenses as a percentage of operating revenue) was 84.3% during the six months ended June 30, 2017 compared with 86.2% during the six months ended June 30, 2016.  Our non-GAAP adjusted operating ratio⁽¹⁾ (operating expenses as a percentage of operating revenues, net of fuel surcharge) was 82.3% during the six months ended June 30, 2017, compared to 84.8% during the six months ended June 30, 2016. Net income decreased $2.1 million (6.8)%, to $28.7 million for the six months ended June 30, 2017 from $30.7 million during the compared 2016 period as a result of the net effects discussed above.

Liquidity and Capital Resources

The growth of our business requires significant investments in new revenue equipment.  Historically, except for acquisitions, we have been debt-free, funding revenue equipment purchases with cash flow provided by operating activities and sales of equipment. Our primary source of liquidity is cash flow provided by operating activities. We entered into a line of credit during the fourth quarter of 2013, described below, to partially finance an acquisition, including the payoff of debt we assumed. Our primary source of liquidity during 2017 was cash flow generated from operating activities. During 2017, we were able to fund revenue equipment purchases with cash flows provided by operating activities and sales of equipment. We believe we have adequate liquidity to meet our current and projected needs in the foreseeable future. We expect to have significant capital requirements over the long-term, which we expect to fund with cash flows provided by operating activities, proceeds from the sale of used equipment, and available capacity on the Credit Agreement. At June 30, 2017, we had $171.3 million in cash and cash equivalents, no outstanding debt, and $171.3 million available borrowing capacity on the Credit Agreement. Immediately following the acquisition of IDC on July 6, 2017, of which we paid cash, we had approximately $81.0 million of available cash and approximately $23.0 million of assumed debt. We expect to repay the assumed debt during the quarter ending September 30, 2017.

In November 2013, we entered into a Credit Agreement with Wells Fargo Bank, National Association, (the “Bank”). Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit, which was used to assist in the repayment of all debt acquired at the time of acquisition, and which may be used for future working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $175.0 million on November 1, 2016 through October 31, 2018.

The Credit Agreement is unsecured, with a negative pledge against all assets of our consolidated group, except for debt associated with permitted acquisitions, new purchase-money debt and capital lease obligations as described in the Credit Agreement. The Credit Agreement matures on October 31, 2018, and may be terminated at any time without penalty. Borrowings under the Credit Agreement can either be, at the Borrower's election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0%, floating. The weighted average variable annual percentage rate is not calculated since there were no amounts borrowed and outstanding at June 30, 2017. There is a commitment fee on the unused portion of the line of credit under the Credit Agreement at 0.0625%, due monthly.

The Credit Agreement contains customary financial covenants measured quarterly, including, but not limited to, (i) a maximum adjusted leverage ratio of 2.0 to 1.0, (ii) required minimum net income of $1.00, and (iii) required minimum tangible net worth of $175.0 million. The Credit Agreement also includes customary events of default, covenants, representations and warranties, and indemnification provisions. We were in compliance with the respective financial covenants during 2017 and 2016.

Operating cash flow during the six months ended June 30, 2017 was $50.8 million compared to $77.9 million during the same period of 2016.  This was primarily a result of net income (excluding non-cash depreciation and amortization, changes in deferred taxes, and gains on disposal of equipment) being approximately $8.8 million lower during 2017 compared to 2016 and a decrease in cash flow generated by operating assets and liabilities of approximately $18.5 million.  The net decrease in cash provided by operating assets and liabilities for 2017 compared to the same period of 2016 was primarily attributable to the timing of accrual and prepaid operational and income tax payments comparing the two periods. Cash flow from operating activities was 19.6% of operating revenues for the six months ended June 30, 2017 compared with 24.1% for the same period of 2016.

Cash flows used in investing activities was $4.6 million during the six months ended June 30, 2017 compared to cash flows used in investing activities of $15.5 million during the comparative 2016 period or an increase in cash of $10.9 million. The increase in cash from investing activities was primarily the net result of the net proceeds from sale of property and equipment, less equipment purchases. We currently estimate a total of approximately $40 to $50 million in net capital expenditures for the calendar year 2017.

22

Cash used in financing activities decreased $14.6 million during the three months ended June 30, 2017 compared to the same period of 2016 due mainly to $14.7 million less cash used for repurchases of common stock as no shares were repurchased in 2017 compared to $14.7 million in 2016. There were no borrowings on the Credit Agreement during the three months ended June 30, 2017.

We have a stock repurchase program with 3.3 million shares remaining authorized for repurchase under the program as of June 30, 2017 and the program has no expiration date. There were no shares repurchased in the open market during the six months ended June 30, 2017 and 0.9 million shares were repurchased during the six months ended June 30, 2016. Shares repurchased were accounted for as treasury stock. Repurchases are expected to continue from time to time, as determined by market conditions, cash flow requirements, securities law limitations, and other factors, until the number of shares authorized have been repurchased, or until the authorization is terminated. The share repurchase authorization is discretionary and has no expiration date.

We paid income taxes, net of refunds, of $14.0 million and $23.4 million in the six months ended June 30, 2017 and June 30, 2016. Management believes we have adequate liquidity to meet our current and projected needs in the foreseeable future.  Management believes we will continue to have significant capital requirements over the long-term, which we expect to fund with cash flows provided by operating activities, proceeds from the sale of used equipment and available capacity on the Credit Agreement.  At June 30, 2017, the Company had $171.3 million in cash and cash equivalents and $171.3 million available borrowing capacity on the Credit Agreement.

Off-Balance Sheet Transactions

Our liquidity or financial condition is not materially affected by off-balance sheet transactions. We are a party to certain operating leases related to our terminal facilities. Operating lease expense during the six months ended June 30, 2017 was $1.0 million.

Risk Factors

You should refer to Item 1A of our Annual Report (Form 10-K) for the year ended December 31, 2016, under the caption “Risk Factors” for specific details on the following factors that are not within the control of the Company and could affect our financial results.

• Our business is subject to general economic, credit, business, and regulatory factors affecting the trucking industry that are largely out of our control, any of which could have a materially adverse effect on our operating results.

• Our growth may not continue at historical rates, if at all, and any decrease in revenues or profits may impair our ability to implement our business strategy, which could have a materially adverse effect on our results of operations.

• We operate in a highly competitive and fragmented industry, and numerous competitive factors could impair our ability to improve our profitability and could have a materially adverse effect on our results of operations.

• We are highly dependent on a few major customers, the loss of one or more of which could have a materially adverse effect on our business.

• The incurrence of indebtedness under our Credit Agreement or lack of access to other financing sources could have adverse consequences on our future operations.

• We have significant ongoing capital requirements that could affect our profitability if we are unable to generate sufficient cash from operations and obtain financing on favorable terms.

• Increased prices for new revenue equipment, design changes of new engines, decreased availability of new revenue equipment, and decreased demand for and value of used equipment could have a materially adverse effect on our business, financial condition, results of operations, and profitability.

• If fuel prices increase significantly, our results of operations could be adversely affected.

• Increases in driver compensation or difficulties in attracting and retaining qualified drivers, including independent contractors, may have a materially adverse effect on our profitability and the ability to maintain or grow our fleet.

• If our independent contractors are deemed by regulators or judicial process to be employees, our business, financial condition and results of operations could be adversely affected.

• We operate in a highly regulated industry, and changes in existing regulations or violations of existing or future regulations could have a materially adverse effect on our operations and profitability.

• The CSA program adopted by the FMCSA could adversely affect our profitability and operations, our ability to maintain or grow our fleet, and our customer relationships.

• Receipt of an unfavorable DOT safety rating could have a materially adverse effect on our operations and profitability.

• Compliance with various environmental laws and regulations may increase our costs of operations and non-compliance with such laws and regulations could result in substantial fines or penalties.

23

• We are exposed to risks related to our acquisition of Interstate Distributor Co. ("IDC") and we may not be able to achieve the benefits we expected at the time of the acquisition. Any failure to implement our business strategy with respect to the IDC acquisition could negatively impact our business, financial condition and results of operations.

• We may not make acquisitions in the future, or if we do, we may not be successful in integrating the acquired company, either of which could have a materially adverse effect on our business.

• If we are unable to retain our key employees or find, develop and retain a core group of managers, our business, financial condition, and results of operations could be materially adversely affected.

• Seasonality and the impact of weather and other catastrophic events affect our operations and profitability.

• We self-insure for a significant portion of our claims exposure, which could significantly increase the volatility of, and decrease the amount of, our earnings.

• We depend on the proper functioning and availability of our information systems and a system failure or unavailability or an inability to effectively upgrade our information systems could cause a significant disruption to our business and have a materially adverse effect on our results of operations.

• Concentrated ownership of our stock can influence stockholder decisions, may discourage a change in control, and may have an adverse effect on share price of our stock.

• Developments in labor and employment law and any unionizing efforts by employees could have a materially adverse effect on our results of operations.

• Litigation may adversely affect our business, financial condition, and results of operations.

24

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General

We are exposed to market risk changes in interest rates during periods when we have outstanding borrowings and from changes in commodity prices, primarily fuel and rubber. We do not currently use derivative financial instruments for risk management purposes, although we have used instruments in the past for fuel price risk management, and do not use them for either speculation or trading. Because substantially all of our operations are confined to the United States, we are not directly subject to a material foreign currency risk.

Interest Rate Risk

We had no debt outstanding at June 30, 2017 although we had $171.3 million in available borrowings on our Credit Agreement. Borrowings under the Credit Agreement can either be, at our election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0.0%, floating. The current borrowing rate available on the Credit Agreement was 1.852%. Increases in interest rates could impact our interest expense on future borrowings.

Commodity Price Risk

We are subject to commodity price risk primarily with respect to purchases of fuel and rubber. We have fuel surcharge agreements with most customers that enable us to pass through most long-term price increases therefore limiting our exposure to commodity price risk. Fuel surcharges that can be collected do not always fully offset an increase in the cost of fuel as we are not able to pass through fuel costs associated with out-of-route miles, empty miles, and tractor idle time. Based on our actual fuel purchases for 2016, assuming miles driven, fuel surcharges as a percentage of revenue, percentage of unproductive miles, and miles per gallon remained consistent with 2016 amounts, a $1.00 increase in the average price of fuel per gallon, year over year, would decrease our income before income taxes by approximately $6.3 million in 2017. We use a significant amount of tires to maintain our revenue equipment. We are not able to pass through 100% of price increases from tire suppliers due to the severity and timing of increases and current rate environment. Historically, we have sought to minimize tire price increases through bulk tire purchases from our suppliers. Based on our expected tire purchases for 2017, a 10% increase in the price of tires would increase our tire purchase expense by $0.1 million, resulting in a corresponding decrease in income before income taxes.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures– We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Accounting and Financial Officer), of the effectiveness of the design and operations of our disclosure controls and procedures, as defined in Exchange Act Rule 15d-15(e). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective in enabling us to record, process, summarize and report information required to be included in our periodic SEC filings within the required time period.

Changes in Internal Control Over Financial Reporting – There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

25

PART II

We are a party to ordinary, routine litigation and administrative proceedings incidental to our business. These proceedings primarily involve claims for personal injury, property damage, cargo, and workers’ compensation incurred in connection with the transportation of freight.  We maintain insurance to cover liabilities arising from the transportation of freight for amounts in excess of certain self-insured retentions.

Basis of Presentation and New Accounting Pronouncements

Heartland Express, Inc. (the “Company,” “we,” “us,” or “our”), is a holding company incorporated in Nevada, which owns all of the stock of Heartland Express Inc. of Iowa, Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. Gordon Trucking, Inc. ("GTI") was merged into Heartland Express Inc. of Iowa effective July 1, 2016. We, and our subsidiaries, operate as one segment. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load) with corporate headquarters in North Liberty, Iowa. We primarily provide nationwide asset-based dry van truckload service for major shippers from Washington to Florida and New England to California.

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned.  All material intercompany items and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes to the financial statements required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all normal, recurring adjustments considered necessary for a fair presentation have been included. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on February 28, 2017. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods. There were no changes to the Company's significant accounting policies during the six month period ended June 30, 2017, except as noted below in regards to the accounting for employee share based payments.

In May 2017, the Financial Accounting Standards Boards (FASB) issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," to provide clarity and reduce diversity and complexity of applying the accounting guidance in Topic 718 to a change in the terms or conditions of a share-based payment award. An entity should account for the effects of a modification unless certain criteria are met. The provisions of this update are effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements and we expect to adopt this standard prospectively for interim and annual periods beginning January 1, 2018.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” which continues to require an entity to review indicators for impairment, perform qualitative assessments, and analyze the fair value of a reporting unit as compared to the carrying value of goodwill for potential impairment but eliminates or replaces additional tests and assessments within the prior guidance. The provisions of this update are effective for fiscal years beginning after December 15, 2019, with early adoption permitted for impairment measurement tests occurring after January 1, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we are unable to predict whether the amount of restricted cash to be included will be material to our statement of cash flows at this time, but we fully intend to include and explain the change in restricted cash upon adoption of the standard.

Further ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our consolidated cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". This update requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Based

on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In March, 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". This update seeks to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. This update was effective for the Company beginning January 1, 2017 and was adopted accordingly, including forfeitures being recorded as incurred, during the first quarter ended March 31, 2017 and for future periods. The adoption did not have a material impact on our financial statements and prior periods presented have not been adjusted.

In February 2016, the FASB issued ASU 2016-02, "Leases". This update seeks to increase the transparency and comparability among entities by requiring public entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. To satisfy the standard’s objective, a lessee will recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a lease liability for the obligation to make lease payments. Both the right-of-use asset and lease liability will initially be measured at the present value of the lease payments, with subsequent measurement dependent on the classification of the lease as either a finance or an operating lease. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term.

In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for public companies for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. Based on our initial assessment, we believed the impact of adoption of the standard would not have a material impact on our financial statements. We have not yet performed an updated assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington ("IDC"). We expect to complete an updated combined assessment and select a transition method by January 1, 2019, our date of transition.

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. We have been closely monitoring FASB activity related to the new standard and are evaluating the effect that the new guidance will have on our consolidated financial statements and related disclosures. We have performed an analysis of our revenue transactions across the operations for our legacy operations as they existed through June 30, 2017, and based on that we believed that our adoption would not have a material impact on our operating revenue or operating income as a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We have not yet performed our assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of IDC. We expect to complete an updated combined assessment and select a transition method by January 1, 2018, our date of transition.

Use of Estimates [Abstract]

Use of Estimates

Use of EstimatesThe preparation of the consolidated 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. There were no significant changes in estimates and assumptions used by management related to our critical accounting policies during the three and six months ended June 30, 2017.

Segment Information [Abstract]

Segment Information

Segment InformationWe provide truckload services across the United States (U.S.) and parts of Canada. These truckload services are primarily asset-based transportation services in the dry van truckload market, and we also offer truckload temperature-controlled transportation services and non-asset based brokerage services, neither of which are significant to our operations. We exited our non-asset-based freight brokerage business in the first quarter of 2017. Our Chief Operating Decision Maker oversees and manages all of our transportation services, on a combined basis, including previously acquired entities. As a result of the foregoing, we have determined that we have one segment, consistent with the authoritative accounting guidance on disclosures about segments of an enterprise and related information.

Property, Plant and Depreciation [Abstract]

Property, Equipment, and Depreciation

Prepaid Tires, Property, Equipment, and DepreciationProperty and equipment are reported at cost, net of accumulated depreciation. Maintenance and repairs are charged to operations as incurred.  New tires are capitalized separately from revenue equipment and are reported separately as “Prepaid tires” in the consolidated balance sheets and amortized over two years.  Depreciation for financial statement purposes is computed by the straight-line method for all assets other than tractors.  We recognize depreciation expense on tractors using the 125% declining balance method. New tractors are depreciated to salvage values of $15,000 while new trailers are depreciated to salvage values of $4,000.

Other Intangibles, Net and Goodwill

All intangible assets determined to have finite lives are amortized over their estimated useful lives. The useful life of an intangible asset is the period over which the asset is expected to contribute directly or indirectly to future cash flows. There was no change in the gross amount of identifiable intangible assets during the three and six months ended June 30, 2017. Amortization expense of $0.5 million, $1.0 million and $0.5 million, $1.0 million for the three and six months ended June 30, 2017 and 2016, respectively, was included in depreciation and amortization in the consolidated statements of comprehensive income. Intangible assets subject to amortization consisted of the following at June 30, 2017:

Stock-Based Compensation [Abstract]

Stock Based Compensation

Stock-Based Compensation

In July 2011, a Special Meeting of Stockholders of Heartland Express, Inc. was held, at which meeting the approval of the Plan was ratified. The Plan is administered by the Compensation Committee of our Board of Directors. Per the terms of the awards, employees receiving awards will have all of the rights of a stockholder with respect to the unvested restricted shares including, but not limited to, the right to receive such cash dividends, if any, as may be declared on such shares from time to time and the right to vote such shares at any meeting of our stockholders.

The Plan made available up to 0.9 million shares for the purpose of making restricted stock grants to our eligible officers and employees. Shares granted in 2013 through 2017 have various vesting terms that range from immediate to four years from the date of grant. Once vested, there are no other restrictions on the awards. Compensation expense associated with these awards is based on the market value of our stock on the grant date. Our market closing price ranged between $13.86 and $18.18 on the various grant dates for the shares granted in 2013. The Company's market close price ranged between $21.72 and $27.47 on the various grant dates during 2014, ranged between $19.93 and $27.29 on the various grant dates during 2015, and ranged between $17.06 and $18.78 on the various grant dates during 2016. The Company's market close price was $20.53 for the grant date during the six months ended June 30, 2017. There were no significant assumptions made in determining the fair value. Compensation expense associated with restricted stock awards is included in salaries, wages and benefits in the consolidated statements of comprehensive income. Compensation expense associated with restricted stock awards was $0.2 million and $0.3 million, for the three and six ended June 30, 2017. Compensation expense associated with restricted stock awards was $0.3 million and $1.0 million for the three and six ended June 30, 2016, respectively. Unrecognized compensation expense was $0.2 million at June 30, 2017 which will be recognized over a weighted average period of 1.1 years.

Line of Credit, Long-Term Debt [Abstract]

Long-Term Debt

Long-Term Debt

In November 2013, we entered into a Credit Agreement with Wells Fargo Bank, National Association, (the “Bank”). Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit which may be used for future working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $175.0 million on November 1, 2016 through October 31, 2018.

The Credit Agreement is unsecured, with a negative pledge against all assets of our consolidated group, except for debt associated with permitted acquisitions, new purchase-money debt and capital lease obligations as described in the Credit Agreement. The Credit Agreement matures on October 31, 2018. The Borrower has the ability to terminate the commitment at any time at no additional cost to the Borrower. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus 0.625%, floating, or (ii) Prime (Index) plus 0.0%, floating. There is a commitment fee on the unused portion of the Revolver at 0.0625%, due monthly.

The Credit Agreement contains customary financial covenants including, but not limited to, (i) a maximum adjusted leverage ratio of 2:1, measured quarterly on a trailing twelve month basis, (ii) a minimum net income requirement of $1.00, measured quarterly on a trailing twelve month basis, (iii) a minimum tangible net worth of $175.0 million requirement, measured quarterly, and (iv) limitations on other indebtedness and liens. The Credit Agreement also includes customary events of default, conditions, representations and warranties, and indemnification provisions. We were in compliance with the respective financial covenants at June 30, 2017.

We had no outstanding long-term debt at June 30, 2017 or December 31, 2016. Outstanding letters of credit associated with the revolving line of credit at June 30, 2017 were $3.7 million. As of June 30, 2017, the line of credit available for future borrowing was $171.3 million.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We use the asset and liability method of accounting for income taxes.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when temporary differences reverse. The effe

ct of a change in tax rates on deferred taxes is recognized in the period that the change is enacted. A valuation allowance is recorded to reduce the Company's deferred tax assets to the amount that is more likely than not to be realized. We had no recorded valuation allowance at June 30, 2017 and December 31, 2016. Our effective tax rate was 32.8% and 33.5% for the three months ended and 30.8% and 31.6% for the six months ended June 30, 2017 and 2016, respectively.  

We recognize the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  We record interest and penalties related to unrecognized tax benefits in income tax expense.

At June 30, 2017 and December 31, 2016, we had a total of $5.9 million and $8.8 million in gross unrecognized tax benefits, respectively included in long-term income taxes payable in the consolidated balance sheet.  Of this amount, $4.0 million and $5.7 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of June 30, 2017 and December 31, 2016.  The net decrease in unrecognized tax benefits was $1.2 million and $1.3 million during the three months ended June 30, 2017 and 2016, respectively.  The net decrease in unrecognized tax benefits was $2.9 million and $1.7 million during the six months ended June 30, 2017 and 2016, respectively. The net decrease during the three and six month periods of 2017 and 2016 was mainly due to the expiration of certain statues of limitation net of additions and settlements with respective states. This had the effect of decreasing the effective state tax rate during these respective periods. The total net amount of accrued interest and penalties for such unrecognized tax benefits was $1.9 million and $3.2 million at June 30, 2017 and December 31, 2016 and is included in long-term income taxes payable in the consolidated balance sheets.  Income tax expense is increased each period for the accrual of interest on outstanding positions and penalties when the uncertain tax position is initially recorded. Income tax expense is reduced in periods by the amount of accrued interest and penalties associated with reversed uncertain tax positions due to lapse of applicable statute of limitations, when applicable or when a position is settled.

Net interest and penalties included in income tax expense for the three month period ended June 30, 2017 and 2016 was a net benefit of approximately $0.5 million and $0.9 million, respectively. Net interest and penalties included in income tax expense for the six month period ended June 30, 2017 and 2016 was a net benefit of approximately $1.3 million and $1.6 million, respectively. Income tax expense decreased during the three and six months ended June 30, 2017 and 2016 due to reductions for the expiration of applicable statute of limitations. These unrecognized tax benefits relate to risks associated with state income tax filing positions for our corporate subsidiaries.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2017
	(in thousands)
Balance at January 1, 2017	$	8,751
Additions based on tax positions related to current year	145
Additions for tax positions of prior years	—
Reductions for tax positions of prior years	(415		)
Reductions due to lapse of applicable statute of limitations	(2,602		)
Settlements	(17		)
Balance at June 30, 2017	$	5,862

A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. We do not have any outstanding litigation related to tax matters.  At this time, management’s best estimate of the reasonably possible change in the amount of gross unrecognized tax benefits to be a decrease of approximately $1.5 million to a decrease of $2.5 million during the next twelve months mainly due to the expiration of certain statute of limitations, net of additions.  The federal statute of limitations remains open for the years 2014 and forward. Tax years 2007 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.

Operating Leases

There were no leases for revenue equipment for the three and six months ended June 30, 2017. During 2016, we leased certain revenue equipment of which the majority of these leases were with a commercial tractor dealership, which is partially owned by one of our board members. Rent expense for these leases was $0.3 million and $0.8 million (including related-party rental payments totaling $0.3 million and $0.8 million), for the three and six months ended June 30, 2016. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income. The leases were terminated in June 2016.

We lease certain terminal facilities under operating leases. A portion of these leases are with limited liability companies, whose members include one of our board members and a commercial tractor dealership whose owners include one of our board members. The related-party rental payments were entered into as a result of a previous acquisition. Rent expenses for terminal facilities were $0.5 million and $1.0 million (including related-party rental payments totaling $0.4 million and $0.8 million), for the three and six months ended June 30, 2017. Rent expenses for terminal facilities were $0.5 million and $1.1 million (including related-party rental payments totaling $0.5 million and $0.9 million), for the three and six months ended June 30, 2016. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire from 2017 through 2018 and contain purchase options and options to renew, except the Pacific, Washington location. We have renewal options and a right of first refusal on the sale of the Pacific, Washington location property. We are responsible for all taxes, insurance, and utilities related to the terminal leases. See Note 13 for additional information regarding related party transactions.

Heartland Express, Inc. (the “Company,” “we,” “us,” or “our”), is a holding company incorporated in Nevada, which owns all of the stock of Heartland Express Inc. of Iowa, Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. Gordon Trucking, Inc. ("GTI") was merged into Heartland Express Inc. of Iowa effective July 1, 2016. We, and our subsidiaries, operate as one segment. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load) with corporate headquarters in North Liberty, Iowa. We primarily provide nationwide asset-based dry van truckload service for major shippers from Washington to Florida and New England to California.

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned.  All material intercompany items and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes to the financial statements required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all normal, recurring adjustments considered necessary for a fair presentation have been included. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on February 28, 2017. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods.

New Accounting Pronouncements, Policy [Policy Text Block]

In May 2017, the Financial Accounting Standards Boards (FASB) issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," to provide clarity and reduce diversity and complexity of applying the accounting guidance in Topic 718 to a change in the terms or conditions of a share-based payment award. An entity should account for the effects of a modification unless certain criteria are met. The provisions of this update are effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements and we expect to adopt this standard prospectively for interim and annual periods beginning January 1, 2018.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” which continues to require an entity to review indicators for impairment, perform qualitative assessments, and analyze the fair value of a reporting unit as compared to the carrying value of goodwill for potential impairment but eliminates or replaces additional tests and assessments within the prior guidance. The provisions of this update are effective for fiscal years beginning after December 15, 2019, with early adoption permitted for impairment measurement tests occurring after January 1, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we are unable to predict whether the amount of restricted cash to be included will be material to our statement of cash flows at this time, but we fully intend to include and explain the change in restricted cash upon adoption of the standard.

Further ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our consolidated cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". This update requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Based

on our initial assessment, we believe the impact of adoption of the standard will not have a material impact on our financial statements.

In March, 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". This update seeks to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. This update was effective for the Company beginning January 1, 2017 and was adopted accordingly, including forfeitures being recorded as incurred, during the first quarter ended March 31, 2017 and for future periods. The adoption did not have a material impact on our financial statements and prior periods presented have not been adjusted.

In February 2016, the FASB issued ASU 2016-02, "Leases". This update seeks to increase the transparency and comparability among entities by requiring public entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. To satisfy the standard’s objective, a lessee will recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a lease liability for the obligation to make lease payments. Both the right-of-use asset and lease liability will initially be measured at the present value of the lease payments, with subsequent measurement dependent on the classification of the lease as either a finance or an operating lease. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term.

In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for public companies for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. Based on our initial assessment, we believed the impact of adoption of the standard would not have a material impact on our financial statements. We have not yet performed an updated assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington ("IDC"). We expect to complete an updated combined assessment and select a transition method by January 1, 2019, our date of transition.

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. We have been closely monitoring FASB activity related to the new standard and are evaluating the effect that the new guidance will have on our consolidated financial statements and related disclosures. We have performed an analysis of our revenue transactions across the operations for our legacy operations as they existed through June 30, 2017, and based on that we believed that our adoption would not have a material impact on our operating revenue or operating income as a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We have not yet performed our assessment after July 6th, 2017, when we acquired 100% of the outstanding stock of IDC. We expect to complete an updated combined assessment and select a transition method by January 1, 2018, our date of transition.

Use of Estimates, Policy [Policy Text Block]

Use of EstimatesThe preparation of the consolidated 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.

Segment Reporting, Policy [Policy Text Block]

Segment Information

We provide truckload services across the United States (U.S.) and parts of Canada. These truckload services are primarily asset-based transportation services in the dry van truckload market, and we also offer truckload temperature-controlled transportation services and non-asset based brokerage services, neither of which are significant to our operations. We exited our non-asset-based freight brokerage business in the first quarter of 2017. Our Chief Operating Decision Maker oversees and manages all of our transportation services, on a combined basis, including previously acquired entities. As a result of the foregoing, we have determined that we have one segment, consistent with the authoritative accounting guidance on disclosures about segments of an enterprise and related information.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash EquivalentsCash equivalents are short-term, highly liquid investments with insignificant interest rate risk and original maturities of three months or less at acquisition.

Property, Plant and Equipment, Policy [Policy Text Block]

Prepaid Tires, Property, Equipment, and DepreciationProperty and equipment are reported at cost, net of accumulated depreciation. Maintenance and repairs are charged to operations as incurred.  New tires are capitalized separately from revenue equipment and are reported separately as “Prepaid tires” in the consolidated balance sheets and amortized over two years. Depreciation for financial statement purposes is computed by the straight-line method for all assets other than tractors.  We recognize depreciation expense on tractors using the 125% declining balance method. New tractors are depreciated to salvage values of $15,000 while new trailers are depreciated to salvage values of $4,000.

Earnings Per Share, Policy [Policy Text Block]

Earnings per ShareBasic earnings per share is based upon the weighted average common shares outstanding during each year.  Diluted earnings per share is based on the basic weighted earnings per share with additional weighted common shares for common stock equivalents.

Income Tax, Policy [Policy Text Block]

Income Taxes

We use the asset and liability method of accounting for income taxes.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when temporary differences reverse. The effe

ct of a change in tax rates on deferred taxes is recognized in the period that the change is enacted. A valuation allowance is recorded to reduce the Company's deferred tax assets to the amount that is more likely than not to be realized.

Income Tax Uncertainties, Policy [Policy Text Block]

We recognize the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  We record interest and penalties related to unrecognized tax benefits in income tax expense.

Subsequent Events, Policy [Policy Text Block]

Subsequent EventsOn July 6, 2017, we acquired 100% of the outstanding stock of Interstate Distributor Co. of Tacoma, Washington ("IDC") from Saltchuk Resources, Inc. ("Saltchuk"). The acquisition allows us to add high quality drivers, experienced personnel, and a strong customer base to our operations. We gained additional traffic density in the West, and our stronger Eastern network will improve service for IDC's customers in the East. We have not completed the initial accounting for the acquisition and we are still collecting certain pre-acquisition financial information to complete our supplemental proforma information. The transaction enterprise value was approximately $113 million and includes approximately $94 million in cash for the equity, $23 million in assumed debt, and $4 million in acquired cash.
