NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1.  Basis of Presentation

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, Gordon Trucking, Inc. (“GTI”), Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. 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, 2014 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on March 2, 2015. 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 three month period ended March 31, 2015.

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 months ended March 31, 2015.

Note 3. Segment Information

We provide multiple transportation services across the United States (U.S.) and parts of Canada. We offer primarily asset-based transportation services in the dry van truckload market and also offer truckload temperature-controlled transportation services and non-asset based brokerage services. None of our transportation services or geographical-based regional terminals individually meet the definition of a segment. Our Chief Operating Decision Maker oversees and manages all of our transportation services and regional terminals, on a combined basis, including the legacy transportation services of 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 March 31, 2015, restricted and designated cash and investments totaled $29.2 million and $18.2 million was included in other current assets and $11.0 million was included in other non-current assets in the consolidated balance sheets. Restricted and designated cash and investments totaled $12.6 million at December 31, 2014, all of which was included in other non-current assets in the consolidated balance sheets.  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.  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 expense of $0.3 million and $0.3 million for the three

7

months ended March 31, 2015 and 2014, respectively, have been included in communication and utilities in the consolidated statements of comprehensive income. 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 months ended March 31, 2015. Amortization expense of $0.6 million and $0.6 million for the three months ended March 31, 2015 and 2014, respectively, was included in depreciation and amortization in the consolidated statement of comprehensive income. Intangible assets subject to amortization consisted of the following at March 31, 2015:

	Amortization period (years)	Gross Amount		Accumulated Amortization		Net intangible assets
		(in thousands)
Customer relationships	20	$	7,600	$	523	$	7,077
Tradename	6	7,400		1,696		5,704
Covenants not to compete	10	3,100		429		2,671
Real estate options	2.2	942		640		302
		$	19,042	$	3,288	$	15,754

Carrying amounts of goodwill were as follows:

	(in thousands)
Balance at December 31, 2014	$	100,212
Acquisitions	—
Balance at March 31, 2015	$	100,212

Goodwill is tested at least annually for impairment by applying a fair value based analysis in accordance with the authoritative accounting guidance on goodwill and other intangible assets.  Our annual assessment is conducted as of the end of September each year or any other time when indicators requiring further assessment are identified. No indicators requiring further assessment were identified since our last assessment through March 31, 2015. Management determined that no impairment charge was required for the three month periods ended March 31, 2015 and 2014.

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 months ended March 31, 2015 and March 31, 2014, we had outstanding restricted shares of common stock to certain of our employees under the Company's 2011 Restricted Stock Award 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 months ended March 31, 2015 and March 31, 2014 is as follows (in thousands, except per share data):

	Three months ended March 31, 2015
	Net Income (numerator)		Shares (denominator)	Per Share Amount
Basic EPS	$	17,611	87,791	$	0.20
Effect of restricted stock	—		174
Diluted EPS	$	17,611	87,965	$	0.20

8

	Three months ended March 31, 2014
	Net Income (numerator)		Shares (denominator)	Per Share Amount
Basic EPS	$	14,079	87,704	$	0.16
Effect of restricted stock	—		213
Diluted EPS	$	14,079	87,917	$	0.16

Note 8. Equity

In September 2001, our Board of Directors authorized a program to repurchase 15.4 million shares, adjusted for stock splits, of our common stock in open market or negotiated transactions using available cash, cash equivalents and investments which was subsequently amended in February 2012.  Approximately 3.2 million shares remain authorized for repurchase under the program as of March 31, 2015. There were no shares repurchased in the open market during the three months ended March 31, 2015 and 2014. The authorization remains open at March 31, 2015 and has no expiration date. The share repurchase authorization is discretionary and may be suspended or discontinued at any time without prior notice.  

During the three months ended March 31, 2015 and 2014, our Board of Directors declared regular quarterly dividends totaling $1.8 million and $1.8 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 Heartland Express, Inc. 2011 Restricted Stock Award Plan (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. As of March 31, 2015, there were 0.4 million shares that had been granted to employees. The shares granted under the Plan during 2011 are service based awards beginning December 14, 2011 and 20% of the awards vest each June 1st through 2016. There were no shares granted in 2012. The shares granted in 2013 through 2015 are also service based awards and generally vest evenly over three 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 on the December 14, 2011 grant date was $13.57 and ranged between $13.86 and $27.47 on the various grant dates for the shares issued in 2013 through March 31, 2015. 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 $0.3 million and $0.3 million for the three months ended March 31, 2015 and 2014, respectively. Unrecognized compensation expense was $1.1 million at March 31, 2015 which will be recognized over a remaining weighted average period of 1.3 years.

The following tables summarizes our restricted stock award activity for the three months ended March 31, 2015 and 2014.

Note 10.  Long-Term Debt

In November 2013, we entered into a credit agreement (the “Credit Agreement”) by and among Wells Fargo Bank, National Association, (the “Bank”), Heartland Express, Inc. of Iowa as the borrower (the “Borrower”), us, GTI, and the other members of our consolidated group, as Guarantors. Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit. The line of credit is available for working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $225.0 million on November 1, 2014, and will decrease to $200.0 million on November 1, 2015, and to $175.0 million from 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 $200 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 March 31, 2015.

Long term debt consisted of the following at March 31, 2015 and December 31, 2014 (in thousands):

	March 31, 2015		December 31, 2014
Long-term debt	$	—	$	24,600

The weighted average variable annual percentage rate (“APR”) for amounts borrowed and outstanding at December 31, 2014 was 0.79%. Borrowing under the line of credit is recorded in "Long-term debt" in the consolidated balance sheets. Outstanding letters of credit associated with the revolving line of credit at March 31, 2015 were $4.4 million. As of March 31, 2015, the line of credit available for future borrowing was $220.6 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 statements 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 effect 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 March 31, 2015 and December 31, 2014.

10

Our effective tax rate was 37.7% and 31.6% for the three months ended March 31, 2015 and 2014, respectively.  The increase in the effective tax rate for 2015 is primarily attributable to a decrease in favorable income tax expense adjustments in 2015 when compared to the same period in 2014 which had a favorable provision to return adjustment that reduced income tax expense.

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 March 31, 2015 and December 31, 2014, we had a total of $12.1 million and $12.6 million in gross unrecognized tax benefits, respectively.  Of this amount, $7.7 million and $8.0 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of March 31, 2015 and December 31, 2014.  Unrecognized tax benefits were a net decrease of $0.5 million and $0.5 million during the three months ended March 31, 2015 and 2014, respectively. The net decreases during the three month periods of 2015 and 2014 were due mainly to the expiration of certain statutes of limitation net of additions 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 $5.2 million and $5.7 million at March 31, 2015 and December 31, 2014 and is included in income taxes payable in the consolidated balance sheets.  Net interest and penalties included in income tax expense for the three month period ended March 31, 2015 and 2014 was a benefit of approximately $0.5 million and $0.7 million, respectively. 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. Income tax expense was reduced during the three months ended March 31, 2015 and 2014 due to reversals of interest and penalties due to lapse of applicable statute of limitations and settlements, net of additions for interest and penalty accruals during the same period. 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:

	2014
	(in thousands)
Balance at January 1, 2015	$	12,632
Additions based on tax positions related to current year	232
Additions for tax positions of prior years	—
Reductions for tax positions of prior years	(90		)
Reductions due to lapse of applicable statute of limitations	(675		)
Settlements	—
Balance at March 31, 2015	$	12,099

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 $1.0 million to a decrease of $2.0 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 2012 and forward. Tax years 2005 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

We have operating leases for certain revenue equipment. A portion of these leases are with a commercial tractor dealership, owned by a board member and certain of our employees. Rent expense for these leases were $1.1 million and $2.3 million, (including related-party rental payments totaling $1.1 million and $1.8 million), for the three months ended March 31, 2015 and 2014, respectively, and were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire in 2015 and 2016.

11

We lease certain terminal facilities under operating leases. A portion of these leases are with limited liability companies, whose members include a board member and certain of our employees and a commercial tractor dealership owned by a board member and certain of our employees. Rent expenses for terminal facilities were $1.0 million and $1.1 million, (including related-party rental payments totaling $1.0 million and 1.0 million), for the three months ended March 31, 2015 and 2014, respectively, and were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire from 2015 through 2018 and contain options to renew. We have purchase options on the majority of these facilities. We have a right of first refusal on the sale of the Pacific, Washington location property by the owners. We are responsible for all taxes, insurance, and utilities related to the terminal leases. See Notes 6 and 13 for additional information.

Note 13. Related Party

We lease terminal facilities for operations under operating leases from certain limited liability companies, whose members include a board member and certain of our employees and a commercial tractor dealership owned by a board member and certain of our employees. The terminal facility leases have initial five year terms, which began November 11, 2013, with options to renew and options to purchase with the exception of the Pacific, Washington location which contains a right of first refusal on any sale of the property.

We purchased tractors from and sold tractors to the commercial tractor dealership noted above. We have operating leases for certain revenue equipment with the commercial tractor dealership and we also purchased parts and services from the same commercial tractor dealership. We owed the commercial tractor dealership $0.8 million and $0.1 million, included in accounts payable and accrued liabilities in the consolidated balance sheets at March 31, 2015 and December 31, 2014, respectively, for tractors delivered but not paid for prior to these dates and outstanding parts and services. The commercial tractor dealership owed us $2.5 million and $0.0 million, included in other current assets in the consolidated balance sheets at March 31, 2015 and December 31, 2014, respectively, for tractors traded but not paid for prior to those dates.

The related payments (receipts) with related parties for the three months ended March 31, 2015 and 2014 (in thousands) were as follows:

	2015			2014
Payments for tractor purchases	$	2,099		$	11,483

Overview

We 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. During 2013, through an acquisition, we expanded our historical asset-based dry van service offerings with temperature-controlled truckload, and non-asset-based freight brokerage services. Although these additional service offerings were added in late 2013, they are not significant to our operations. We generally earn revenue based on the number of miles per load delivered.  We believe the keys to success are maintaining high levels of customer service and safety which are predicated on the availability of late-model equipment and experienced drivers.  Management believes that our service standards, safety record, and equipment accessibility have made us a core carrier to many of our major 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.

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.  During 2014 and thus far in 2015, the demand for freight services generally outpaced industry capacity. Industry capacity continues to be hindered by an insufficient quantity of qualified drivers, which is further challenged by various regulations that increasingly reduce drivers' availability. Industry regulations, including the thirty minute break within the first eight hours of driving requirement that became effective July 1, 2013, have and will continue to reduce driver utilization compared to previous periods. We cannot predict how future regulations will impact driver utilization. An industry shortage of qualified drivers, in conjunction with reduced driver utilization, creates a favorable rate environment, but also a general industry trend toward increased driver wages to attract and retain qualified drivers. The revenue trends are consistent with what we have experienced in non-committed business in the spot markets. We cannot currently predict how long this trend will continue.

Competition for drivers, which has historically been intense, has recently escalated due to higher demand for freight services and 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. We implemented increases to our base driver pay package effective November 1, 2014, raising driver compensation. Our driver pay package includes future pay increases based on years of continued service to us and increased rates for accident-free miles of operation. Additionally, effective January 1, 2015 we improved detention pay to assist

13

drivers to offset unproductive detention time. These increases have raised average driver pay by approximately 13% during the first quarter of 2015 compared to the first quarter of 2014. We believe this compensation increase solidified our leadership position in terms of driver pay within the industry and rewards our drivers for years of service with safe operating mileage benchmarks which are critical to our operational and financial performance.

Containment of fuel cost continues to be one of management's top priorities as fuel expenses, at 18.3% of operating revenues at March 31, 2015, fuel is our highest cost after salaries, wages and benefits to our drivers and other employees. The average price so far in 2015 has been $2.87 with the latest average Department of Energy ("DOE") price decreasing to $2.81 compared to an average DOE price of $3.96 during the quarter ended March 31, 2014. Although the average price per gallon in 2015 is the lowest it has been since 2010, we currently anticipate that fuel prices will increase throughout 2015. 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. 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 March 31, 2015, 99% of our over-the-road sleeper berth tractor fleet was equipped with idle management controls. At March 31, 2015, the Company’s tractor fleet had an average age of 1.7 years and the Company's trailer fleet had an average age of 4.5 years. As we continue to lower the age of our tractor fleet throughout the remainder of 2015 the overall fuel economy of the tractor fleet is expected to improve.

We continue to focus on growing organically by 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.  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 three months of 2015 with operating revenues of $187.5 million, including fuel surcharges, net income of $17.6 million, and basic net income per share of $0.20 on basic weighted average outstanding shares of 87.8 million compared to operating revenues of $224.5 million, including fuel surcharges, net income of $14.1 million, and basic net income per share of $0.16 on basic weighted average shares of 87.7 million in the first three months of 2014. We posted an 84.9% operating ratio (operating expenses as a percentage of operating revenues) for the three months ended March 31, 2015 compared to 90.8% for the same period of 2014 and a 9.4% net margin (net income as a percentage of operating revenues) for the three months ended March 31, 2015 compared to 6.3% in the same period of 2014. We had total assets of $780.5 million at March 31, 2015. We achieved a return on assets of 11.6% and a return on equity of 19.0% over the immediate past four quarters ended March 31, 2015, compared to 10.4% and 17.6%, respectively, for the immediate past four quarters ended March 31, 2014.  

Our cash flow from operating activities for the three months ended March 31, 2015 of $55.7 million was 29.7% of operating revenues, compared to $32.0 million and 14.3% in the same period of 2014.  During 2015, we used $3.8 million in net investing cash flows, which was the result of net cash proceeds of revenue equipment sales offset by changes in restricted cash funds. We used $24.6 million in financing activities directly related to debt repayments on our line of credit. As a result, our cash and cash equivalents increased $34.9 million during the three months ended March 31, 2015.  We ended the first quarter of 2015 with cash and cash equivalents of $52.2 million.

Three Months Ended March 31, 2015 Compared With the Three Months Ended March 31, 2014

Operating revenue decreased$37.0 million (16.5%), to $187.5 million for the three months ended March 31, 2015 from $224.5 million for the three months ended March 31, 2014.  The decrease in revenue was the result of a $19.8 million (43.2%) decrease in fuel surcharge revenue from $45.9 million in 2014 to $26.1 million in 2015 and a decrease in trucking revenues of $17.1 million (9.6%). 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 the result of a decrease in loaded miles due to a decrease in drivers, offset by an increase in the rate per loaded mile compared to the three months ended March 31, 2014. We expect revenue to be positively impacted through increases in rate per loaded mile due to current market conditions, including a lack of qualified drivers in the industry.

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 a 26.9%decrease in the average Department of Energy ("DOE") diesel fuel prices during the three months ended March 31, 2015 compared to March 31, 2014, as reported by the DOE, along with a decrease in loaded miles.

Salaries, wages, and benefits increased$0.1 million (0.1%), to $71.0 million for the three months ended March 31, 2015 from $70.9 million in the 2014 period.  Salaries, wages and benefits were relatively flat period over period due to the offsetting changes in health insurance and workers compensation costs (increased $1.8 million), driver wages (decreased $1 million), and non-driver employee wages (decreased $0.7 million). Salaries, wages, and benefits overall increased 6.3% as a percentage of operating revenues. The increase as a percentage of operating revenues was driven mainly by our updated driver pay package which increased driver wages paid per mile by 13%, including detention pay for our drivers after one hour, as a percentage of operating revenues

15

which included reduced fuel surcharge revenue and lower loaded miles in the period ended March 31, 2015 as compared to the same period in the prior year. The increase in driver wages per mile are due to current market conditions caused by a lack of qualified drivers in the industry and competition to attract and retain drivers. We currently expect that our expenses relating to driver wages, as a percentage of revenues, will continue to increase in 2015 as compared to 2014, with or without changes in driver miles, due to increases in average driver wages paid per mile implemented in late 2014. Health insurance expense increased $1.1 million due to an increase in severity and frequency of claims. Non-driver wages decreased $0.6 million due to a reduction in number of non-driver employees as we continue to focus on creating operational efficiencies across our consolidated operations.

Rent and purchased transportation decreased$5.2 million (35.7%), to $9.3 million for the three months ended March 31, 2015 from $14.5 million in the comparable period of 2014.  The decrease was attributable to amounts paid to third party carriers on brokered loads (decreased $2.7 million), amounts paid to independent contractors (decreased $1.3 million), and amounts paid for operating leases of revenue equipment (decreased $1.0 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 2015 period as compared to 2014. During the three months ended March 31, 2015, independent contractors accounted for 3.3% of the total fleet miles compared to approximately 3.7% for the same period of 2014.

Fuel decreased$29.0 million (45.8%), to $34.3 million for the three months ended March 31, 2015 from $63.2 million for the same period of 2014. The decrease was primarily the result of cost savings attributable to decreased fuel prices ($18.3 million) and the combination of decreased miles and increased fuel economy on our tractor fleet ($10.7 million). Fuel cost per mile, net of fuel surcharge revenues, decreased44.2% in the 2015 period compared to the same period of 2014, due in part to a 26.9% decrease in the average diesel price per gallon as reported by the DOE. Other factors contributing to the decrease in fuel cost per mile, net of fuel surcharge, included decreased miles and increased fuel economy due to newer, more fuel efficient, revenue equipment, and idle management controls. Although the average price per gallon in 2015 is the lowest it has been since 2010, we currently anticipate that fuel prices will increase throughout 2015.

Depreciation increased$1.4 million (5.7%), to $26.0 million during the three months ended March 31, 2015 from $24.6 million in the same period of 2014.  The increase is mainly attributable to an increase in the average depreciation expense per revenue equipment units (tractors and trailers) being depreciated. Tractor depreciation increased $1.7 million, on a 5.8% decrease in the number of tractor units depreciated during the three months ended March 31, 2015 compared to the 2014 period. As tractors are depreciated using the declining balance method, depreciation expense is highest in the first year of use and declines in subsequent years and therefore depreciation increased due to continued upgrades to our tractor fleet in 2015. Compared to the same period in 2014, trailer depreciation decreased $0.3 million on an 11.3% decrease in the number of trailer units depreciated during the three months ended March 31, 2015. We currently expect this cost to increase in 2015 as we continue to upgrade our tractor and trailer fleets and discontinue use of leases for revenue equipment.

Operating and maintenance expense decreased$2.0 million (19.6%), to $8.1 million during the three months ended March 31, 2015 from $10.1 million in the same period of 2014. The decrease is mainly due to a decrease in the number of revenue equipment units in the fleet and miles driven period over period as discussed above. There were offsetting increases due to costs associated with preparing equipment for sale as we continue to upgrade tractor and trailer fleets. We expect these costs to fluctuate in 2015 based on revenue equipment trading activity and overall fleet reliability.

Gains on the disposal of property and equipment increased$8.1 million (398.3%), to $10.2 million during the three months ended March 31, 2015 from $2.0 million in the same period of 2014.  The increase resulted from an increase in gains on sales of tractor equipment of $2.8 million and an increase in gains on trailer equipment sales of $5.3 million. The increase in gains on tractor sales was the net effect of selling 425% more tractors during 2015, offset by 39% lower gains per unit. The increase in gains on trailer sales was due to a 134% increase in the number of units sold along with a gain per unit increase of 134%. We currently anticipate tractor and trailer equipment sale activity to continue during 2015 as we continue to upgrade our tractor and trailer fleets.

Our effective tax rate was 37.7% and 31.6% for the three months ended March 31, 2015 and 2014, respectively.  The increase in the effective tax rate for 2015 is primarily attributable to a decrease in favorable income tax expense adjustments in 2015 when compared to the same period in 2014 which had a favorable provision to return adjustment that reduced income tax expense.

As a result of the foregoing, our operating ratio (operating expenses as a percentage of operating revenue) was 84.9% during the three months ended March 31, 2015, compared to 90.8% during the three months ended March 31, 2014.  Net income increased$3.5 million (25.1%), to $17.6 million for the three months ended March 31, 2015, from $14.1 million during the same period in 2014 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, 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 has been cash flow provided by operating activities. Our primary source of liquidity during 2015 remains cash flow generated from operating activities, although we maintain our line of credit to provide assistance with additional cash requirements to fund capital expenditures. During the three months ended March 31, 2015, we were able to fund revenue equipment purchases with cash flows provided by operating activities and sales of equipment as well as pay off the outstanding balance on our line of credit, $24.6 million. We currently have no outstanding borrowings on our line of credit.

On November 11, 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 working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $225.0 million on November 1, 2014 and will further decrease to $200.0 million on November 1, 2015, and to $175.0 million for the period 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, subject to the ability of Heartland Express, Inc. of Iowa (the “Borrower”) to terminate the commitment at any time at no additional cost to the Borrower. 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. 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 including, but not limited to, (i) a maximum adjusted leverage ratio of 2:1, measured quarterly, (ii) required minimum net income of $1.00, measured quarterly, (iii) required minimum tangible net worth of $200 million, 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 March 31, 2015.

Operating cash flow during the three months ended March 31, 2015 was $55.7 million compared to $32.0 million during the same period of 2014.  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 $8.4 million lower during 2015 compared to 2014 offset by an increase in cash flow generated by operating assets and liabilities of approximately $32.1 million.  The net increase in cash provided by operating assets and liabilities for 2015 compared to the same period of 2014 was attributable to a decrease in trade receivables, net, due to an increase in cash collected, an increase in accounts payable, accrued liabilities, and other accrued expenses, primarily due to timing of revenue equipment payments, and an increase in the timing of income tax payments and associated net income tax payable position comparing the two periods. Cash flow from operating activities was 29.7% of operating revenues for the three months ended March 31, 2015 compared with 14.3% for the same period of 2014.

Cash flows provided by investing activities was $3.8 million during the three months ended March 31, 2015 compared to cash flows used in investing activities of $19.8 million during the comparative 2014 period or an increase in cash of $23.6 million. The increase in cash provided by investing activities was primarily the net result of an increase in proceeds from sale of property and equipment, net of trades, offset by equipment purchases, $18.8 million. Net cash flows provided by equipment activity was mainly the result of the timing of equipment payments for purchases and receipts from equipment sales. The remaining increase was mainly due to having paid $3 million in 2014 related to acquisition activity and there were no payments of that nature during the three months ended March 31, 2015. We currently anticipate net capital expenditures of approximately $80 million to $90 million for calendar year 2015, most of which relates to upgrading our tractor fleet. We expect to sell trailers during 2015 to partially offset the price of new trailers, although there are no guaranteed commitments from third parties to buy trailers during the remaining months of 2015. Therefore, the estimated net capital expenditures for 2015 could increase if trailer sale commitments from third parties are canceled.

Cash used in financing activities increased $11.6 million during the three months ended March 31, 2015 compared to the same period of 2014 due to repayments of borrowings on the Credit Agreement.

In 2001, our Board of Directors authorized a program to repurchase 15.4 million shares, adjusted for stock splits, of our common stock in open market or negotiated transactions using available cash, cash equivalents and investments which was subsequently amended in February 2012 to increase the remaining number of authorized shares for repurchase to 5 million.

million shares remain authorized for repurchase under the program as of March 31, 2015. The repurchase program may be suspended, modified, or discontinued at any time without prior notice.  

We paid income taxes, net of refunds, of $0.5 million and $0.4 million in the three months ended March 31, 2015 and March 31, 2014.

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 March 31, 2015, the Company had $52.2 million in cash and cash equivalents and $220.6 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 to finance a portion of our revenue equipment requirements and terminal facilities. Operating lease expense during the three months ended March 31, 2015 was $2.1 million.

New Accounting Pronouncements

In May, 2014, the Financial Accounting Standards Board issued new accounting guidance, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The guidance will replace most existing revenue recognition in GAAP when it becomes effective. The guidance will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. In April 2015, the FASB proposed to defer the effective date of this guidance by one year, with early adoption permitted on the original effective date. The new guidance permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that the new guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

Risk Factors

You should refer to Item 1A of our Annual Report (Form 10-K) for the year ended December 31, 2014, 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 and business 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 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.

• Indebtedness under our Credit Agreement 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, reduced productivity, and restricted availability of new revenue equipment and decreased demand and value of used equipment may adversely affect our earnings and cash flows.

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

• Difficulty in attracting and retaining drivers, including independent contractors, may have a materially adverse effect on our business.

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

• We operate in a highly regulated industry, and increased costs of compliance with, or liability for violation of, existing or future regulations could have a materially adverse effect on our business.

• Safety-related evaluations and rankings under Compliance, Safety, Accountability (CSA) could adversely affect our profitability and operations, our ability to maintain or grow our fleet, and our customer relationships.

• Our operations are subject to various environmental laws and regulations, the violations of which could result in substantial fines or penalties.

• We are exposed to risks related to our acquisition of Gordon Trucking, Inc. ("GTI") 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 GTI acquisition could negatively impact our business, financial condition and results of operations.

18

• 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 terminal managers, our business, financial condition, and results of operations could be adversely affected.

• Seasonality and the impact of weather affect our operations 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 are dependent on computer and communications systems, and a systems failure could cause a significant disruption to our business.

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

• Efforts by labor unions could divert management's attention and could have a materially adverse effect on our operating results.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General

We are exposed to market risk changes in interest rates on our long-term debt 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 the majority of our operations are confined to the United States, we are not subject to a material foreign currency risk.

Interest Rate Risk

We had no debt outstanding at March 31, 2015 although we had $220.6 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%, floating. The current borrowing rate available on the Credit Agreement was 0.811%. 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 diesel 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 diesel 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 expected fuel purchases for 2015, assuming miles driven, fuel surcharges as a percentage of revenue, percentage of unproductive miles, and miles per gallon remained consistent with 2014 amounts, a $1.00 increase in the average price of fuel, year over year, would decrease our earnings by approximately $7.9 million. 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 2015, a 10% increase in the price of tires would increase our tire purchase expense by $1.4 million, resulting in a corresponding decrease in earnings.

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.

19

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 March 31, 2015, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

20

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

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, Gordon Trucking, Inc. (“GTI”), Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. 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, 2014 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on March 2, 2015. 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 three month period ended March 31, 2015.

Long-Term Debt

Line of Credit, Long-Term Debt [Abstract]

Long-Term Debt

Long-Term Debt

In November 2013, we entered into a credit agreement (the “Credit Agreement”) by and among Wells Fargo Bank, National Association, (the “Bank”), Heartland Express, Inc. of Iowa as the borrower (the “Borrower”), us, GTI, and the other members of our consolidated group, as Guarantors. Pursuant to the Credit Agreement, the Bank provided a five-year, $250.0 million unsecured revolving line of credit. The line of credit is available for working capital, equipment financing, and general corporate purposes. The Bank's commitment decreased to $225.0 million on November 1, 2014, and will decrease to $200.0 million on November 1, 2015, and to $175.0 million from 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 $200 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 March 31, 2015.

Long term debt consisted of the following at March 31, 2015 and December 31, 2014 (in thousands):

	March 31, 2015		December 31, 2014
Long-term debt	$	—	$	24,600

The weighted average variable annual percentage rate (“APR”) for amounts borrowed and outstanding at December 31, 2014 was 0.79%. Borrowing under the line of credit is recorded in "Long-term debt" in the consolidated balance sheets. Outstanding letters of credit associated with the revolving line of credit at March 31, 2015 were $4.4 million. As of March 31, 2015, the line of credit available for future borrowing was $220.6 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 statements 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 effect 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 March 31, 2015 and December 31, 2014.

Our effective tax rate was 37.7% and 31.6% for the three months ended March 31, 2015 and 2014, respectively.  The increase in the effective tax rate for 2015 is primarily attributable to a decrease in favorable income tax expense adjustments in 2015 when compared to the same period in 2014 which had a favorable provision to return adjustment that reduced income tax expense.

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 March 31, 2015 and December 31, 2014, we had a total of $12.1 million and $12.6 million in gross unrecognized tax benefits, respectively.  Of this amount, $7.7 million and $8.0 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of March 31, 2015 and December 31, 2014.  Unrecognized tax benefits were a net decrease of $0.5 million and $0.5 million during the three months ended March 31, 2015 and 2014, respectively. The net decreases during the three month periods of 2015 and 2014 were due mainly to the expiration of certain statutes of limitation net of additions 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 $5.2 million and $5.7 million at March 31, 2015 and December 31, 2014 and is included in income taxes payable in the consolidated balance sheets.  Net interest and penalties included in income tax expense for the three month period ended March 31, 2015 and 2014 was a benefit of approximately $0.5 million and $0.7 million, respectively. 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. Income tax expense was reduced during the three months ended March 31, 2015 and 2014 due to reversals of interest and penalties due to lapse of applicable statute of limitations and settlements, net of additions for interest and penalty accruals during the same period. 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:

	2014
	(in thousands)
Balance at January 1, 2015	$	12,632
Additions based on tax positions related to current year	232
Additions for tax positions of prior years	—
Reductions for tax positions of prior years	(90		)
Reductions due to lapse of applicable statute of limitations	(675		)
Settlements	—
Balance at March 31, 2015	$	12,099

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 $1.0 million to a decrease of $2.0 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 2012 and forward. Tax years 2005 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.

Property, Equipment, and Depreciation

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.  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 expense of $0.3 million and $0.3 million for the three months ended March 31, 2015 and 2014, respectively, have been included in communication and utilities in the consolidated statements of comprehensive income. 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.

Basis of Presentation [Abstract]

Basis of Presentation [Policy Text Block]

Basis of Presentation

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, Gordon Trucking, Inc. (“GTI”), Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc., and A & M Express, Inc. 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, 2014 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on March 2, 2015. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods.

Use of Estimates, Policy [Policy Text Block]

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.

Segment Reporting, Policy [Policy Text Block]

Segment Information

We provide multiple transportation services across the United States (U.S.) and parts of Canada. We offer primarily asset-based transportation services in the dry van truckload market and also offer truckload temperature-controlled transportation services and non-asset based brokerage services. None of our transportation services or geographical-based regional terminals individually meet the definition of a segment. Our Chief Operating Decision Maker oversees and manages all of our transportation services and regional terminals, on a combined basis, including the legacy transportation services of 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.

Operating Leases

 Operating Leases

We have operating leases for certain revenue equipment. A portion of these leases are with a commercial tractor dealership, owned by a board member and certain of our employees. Rent expense for these leases were $1.1 million and $2.3 million, (including related-party rental payments totaling $1.1 million and $1.8 million), for the three months ended March 31, 2015 and 2014, respectively, and were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire in 2015 and 2016.

We lease certain terminal facilities under operating leases. A portion of these leases are with limited liability companies, whose members include a board member and certain of our employees and a commercial tractor dealership owned by a board member and certain of our employees. Rent expenses for terminal facilities were $1.0 million and $1.1 million, (including related-party rental payments totaling $1.0 million and 1.0 million), for the three months ended March 31, 2015 and 2014, respectively, and were included in rent and purchased transportation in the consolidated statements of comprehensive income. The various leases expire from 2015 through 2018 and contain options to renew. We have purchase options on the majority of these facilities. We have a right of first refusal on the sale of the Pacific, Washington location property by the owners. We are responsible for all taxes, insurance, and utilities related to the terminal leases. See Notes 6 and 13 for additional information.

There was no change in the gross amount of identifiable intangible assets during the three months ended March 31, 2015. Amortization expense of $0.6 million and $0.6 million for the three months ended March 31, 2015 and 2014, respectively, was included in depreciation and amortization in the consolidated statement of comprehensive income. Intangible assets subject to amortization consisted of the following at March 31, 2015:

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 Heartland Express, Inc. 2011 Restricted Stock Award Plan (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. As of March 31, 2015, there were 0.4 million shares that had been granted to employees. The shares granted under the Plan during 2011 are service based awards beginning December 14, 2011 and 20% of the awards vest each June 1st through 2016. There were no shares granted in 2012. The shares granted in 2013 through 2015 are also service based awards and generally vest evenly over three 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 on the December 14, 2011 grant date was $13.57 and ranged between $13.86 and $27.47 on the various grant dates for the shares issued in 2013 through March 31, 2015. 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 $0.3 million and $0.3 million for the three months ended March 31, 2015 and 2014, respectively. Unrecognized compensation expense was $1.1 million at March 31, 2015 which will be recognized over a remaining weighted average period of 1.3 years.

Segment Information

Segment Information

We provide multiple transportation services across the United States (U.S.) and parts of Canada. We offer primarily asset-based transportation services in the dry van truckload market and also offer truckload temperature-controlled transportation services and non-asset based brokerage services. None of our transportation services or geographical-based regional terminals individually meet the definition of a segment. Our Chief Operating Decision Maker oversees and manages all of our transportation services and regional terminals, on a combined basis, including the legacy transportation services of 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.
