NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1.  Basis of Presentation and New Accounting Pronouncements

Heartland Express, Inc. 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., Midwest Holding Group, LLC and Millis Transfer, LLC. On August 26, 2019, Heartland Express, Inc. of Iowa acquired Midwest Holding Group, Inc. and Millis Real Estate Leasing, LLC (together, "Millis Transfer"), a truckload carrier headquartered in Black River Falls, Wisconsin. Effective December 31, 2019, Millis Transfer, Inc. and Midwest Holding Group, Inc. were converted to Millis Transfer, LLC and Midwest Holding Group, LLC, respectively. Further, effective December 31, 2019, Millis Real Estate Leasing, LLC, Rivera Real Estate, LLC, and Great River Leasing, LLC were merged into Millis Transfer, LLC. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We primarily provide nationwide asset-based dry van truckload service for major shippers from major shippers across the United States.

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned. The consolidated financial results for the three and nine months ended September 30, 2020 include the results of Millis Transfer while the three and nine months ended September 30, 2019 include Millis Transfer only for the period of August 26, 2019 through September 30, 2019. 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. GAAP 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, 2019 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission (the "SEC") on February 25, 2020, as amended on July 21, 2020. 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 nine month period ended September 30, 2020.

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. We have adopted this standard effective January 1, 2020 and the impact of adoption of the standard did not have a material impact on our financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): "Simplifying the Accounting for Income Taxes". The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also clarifies and amends existing guidance to improve consistent application among reporting entities. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within that reporting period; however, early adoption is permitted. We expect to adopt in the period beginning January 1, 2021 and expect the impact to be immaterial to our financial statements.

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 nine months ended September 30, 2020.

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 to select dedicated customers, which are not significant to our operations. Our Chief Operating Decision Maker

7

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. Revenue Recognition

The Company recognizes revenue over time as control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. The delivery of the shipment and completion of the performance obligation allows for the collection of payment generally within 30 days after the delivery date of the shipment for the majority of our customers.

The Company's operations are consistent with those in the trucking industry where freight is hauled twenty-four hours a day and seven days a week, subject to hours of service rules. The Company’s average length of haul is 400-500 miles per trip and each individual shipment accepted by the Company is considered a separate contract with the performance obligation being the delivery of the freight. Our average length of haul for each load of freight generally equals less than one day of continuous transit time. The Company estimates revenue for multiple-stop loads based on miles run and estimates revenue for single stop loads based on transit time, as the customer simultaneously receives and consumes the benefit provided. The Company hauls freight and earns revenue on a consistent basis throughout the periods presented. A corresponding contract asset existed for the estimated revenue of these in-process loads for $1.1 million and $1.2 million at September 30, 2020 and December 31, 2019, respectively. Recorded contract assets are included in the accounts receivable line item of the balance sheet. Corresponding liabilities are recorded in the accounts payable and accrued liabilities and compensation and benefits line items for the estimated expenses on these same in-process loads. The Company had no contract liabilities associated with our operations as of September 30, 2020 and December 31, 2019, respectively.

Total revenues recorded were $162.3 million and $147.9 million for the three months ended September 30, 2020 and 2019, respectively. Fuel surcharge revenues were $14.4 million and $18.4 million for the three months ended September 30, 2020 and 2019, respectively. Accessorial and other revenues recorded in the consolidated statements of comprehensive income collectively represented $3.6 million and $3.5 million for the three months ended September 30, 2020 and 2019, respectively.

Total revenues recorded were $489.5 million and $429.6 million for the nine months ended September 30, 2020 and 2019, respectively. Fuel surcharge revenues were $47.9 million and $53.5 million for the nine months ended September 30, 2020 and 2019, respectively. Accessorial and other revenues recorded in the consolidated statements of comprehensive income collectively represented $10.5 million and $9.1 million for the nine months ended September 30, 2020 and 2019, respectively.

Note 5. 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 September 30, 2020, restricted and designated cash and investments totaled $17.2 million, of which $1.1 million was included in other current assets and $16.1 million was included in other non-current assets in the consolidated balance sheet. Restricted and designated cash and investments totaled $19.4 million at December 31, 2019, of which $1.6 million was included in other current assets and $17.8 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 6. 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 new 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. At September 30, 2020, there were $5.2 million amounts receivable related to equipment sales recorded in other current assets compared to $1.3 million at December 31, 2019.

Note 7. 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 nine months ended September 30, 2020.

8

Amortization expense of $0.6 million and $0.7 million for the three months ended September 30, 2020 and 2019, respectively, was included in depreciation and amortization in the consolidated statements of comprehensive income. Amortization expense of $1.8 million and $1.9 million for the nine months ended September 30, 2020 and 2019, respectively, was included in depreciation and amortization in the consolidated statements of comprehensive income. Intangible assets subject to amortization consisted of the following at September 30, 2020:

	Amortization period (years)	Gross Amount		Accumulated Amortization		Net intangible assets
		(in thousands)
Customer relationships	15-20	$	23,000	$	4,204	$	18,796
Tradename	0.5-6	12,900		8,620		4,280
Covenants not to compete	1-10	5,300		3,033		2,267
		$	41,200	$	15,857	$	25,343

The carrying amount of goodwill was $168.3 million at September 30, 2020 and December 31, 2019, respectively.

Note 8. 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 nine months ended September 30, 2020 and September 30, 2019, we had outstanding restricted shares of common stock to certain of our employees under the Company's 2011 Restricted Stock Award Plan (the "Plan").

Note 9. Equity

We have a stock repurchase program with 6.2 million shares remaining authorized for repurchase as of September 30, 2020. There were no shares repurchased in the open market during the three months ended September 30, 2020 and 2019 respectively. There were 0.7 million shares repurchased in the open market for $12.3 million during the nine months ended September 30, 2020 and there were no shares repurchased during the nine months ended September 30, 2019. 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 months ended September 30, 2020 and 2019, our Board of Directors declared regular quarterly dividends totaling $1.6 million and $1.6 million, respectively.  During the nine months ended September 30, 2020 and 2019, our Board of Directors declared regular quarterly dividends totaling $4.9 million and $4.9 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 10. 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 made available up to 0.9 million shares for the purpose of making restricted stock grants to our eligible officers and employees. There were no shares that were issued during the period 2011 to 2016 that remain unvested at September 30, 2020. Shares granted in 2017 through 2020 have various vesting terms that range from immediate to four years from the date of grant. Compensation expense associated with these awards is based on the market value of our stock on the grant date. Compensation expense associated with restricted stock awards is included in salaries, wages and benefits in the consolidated statements of comprehensive income. There were no significant assumptions made in determining fair value. Compensation expense associated with restricted stock awards was $0.2 million and $1.5 million respectively, for the three and nine months ended September 30, 2020. Compensation expense associated with restricted stock awards was $0.3 million and $1.6 million respectively, for the three and nine months ended September 30, 2019. Unrecognized compensation expense was $0.3 million at September 30, 2020 which will be recognized over a weighted average period of 0.7 years.

The following tables summarize our restricted stock award activity for the three and nine months ended September 30, 2020 and 2019.

Note 11.  Long-Term Debt

In November 2013, Heartland Express, Inc. of Iowa, (the "Borrower"), a wholly owned subsidiary of the Company, 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 original commitment decreased to $175.0 million on November 1, 2016 through scheduled maturity on October 31, 2018. However, on August 31, 2018, Borrower and the Bank entered into the First Amendment to this Credit Agreement. The First Amendment (i) provides for a $100.0 million unsecured revolving line of credit (the “Revolver”), which may be used for working capital, equipment financing, permitted acquisitions, and general corporate purposes, (ii) provides an uncommitted accordion feature, which allows the Company a one-time request, at the discretion of the Bank, to increase the Revolver by up to an additional $100.0 million, (iii) increases the letter of credit subfeature of the Credit Agreement from $20.0 million to $30.0 million, and (iv) extends the maturity of the Credit Agreement to August 31, 2021, subject to the Borrower’s ability to terminate the commitment at any time at no additional cost to the Borrower.

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. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus a spread between 0.700% and 0.900%, based on the Company's consolidated funded debt to adjusted EBITDA ratio or (ii) Prime (Index) plus 0.0%. There is a commitment fee on the unused portion of the Revolver between 0.0725% and 0.1750%, based on the Company's consolidated funded debt to adjusted EBITDA ratio.

11

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 $250.0 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 September 30, 2020 and during the nine months then ended.

We had zero outstanding debt at September 30, 2020 and December 31, 2019, respectively. Outstanding letters of credit associated with the revolving line of credit at September 30, 2020 were $11.5 million. As of September 30, 2020, the line of credit available for future borrowing was $88.5 million.

Note 12.  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 effect of changes 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 September 30, 2020 and December 31, 2019. Our effective tax rate was 24.7% and 25.2% for the three months ended September 30, 2020 and 2019, respectively. The change in the effective tax rate is primarily the result of a favorable prior period provision to actual adjustment. Our effective tax rate was 24.5% and 24.5% for the nine months ended September 30, 2020 and 2019, 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 September 30, 2020 and December 31, 2019, we had a total of $4.7 million and $5.0 million in gross unrecognized tax benefits, respectively included in long-term income taxes payable in the consolidated balance sheet. Of this amount, $3.7 million and $4.0 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of September 30, 2020 and December 31, 2019. The net change in unrecognized tax benefits was a decrease of $0.2 million and a decrease of $0.1 million during the three months ended September 30, 2020 and September 30, 2019, respectively. The net decrease in unrecognized tax benefits during the three months ended September 30, 2020 was due to settlements with corresponding reductions to uncertain tax liabilities net of additions. The net change in unrecognized tax benefits was a decrease of $0.3 million and an increase of $0.3 million during the nine months ended September 30, 2020 and September 30, 2019, respectively. The net decrease in unrecognized tax benefits during the nine months ended September 2020 was mainly due to the expiration of certain statutes of limitation net of additions. This change had the corresponding increasing or decreasing impact on the effective state tax rate during the respective periods. The total net amount of accrued interest and penalties for such unrecognized tax benefits was $0.8 million and $0.9 million at September 30, 2020 and December 31, 2019, respectively 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 September 30, 2020 and September 30, 2019 was a net expense of approximately zero and $0.1 million, respectively. The favorable impact for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was due to the accrual reductions for interest and penalties in excess of settlements. Net interest and penalties included in income tax expense for the nine month period ended September 30, 2020 and September 30, 2019 was a net benefit of approximately $0.1 million and $0.1 million, respectively. The favorable impact for the nine month period ended September 30, 2020 to income tax expense was 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.

12

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

	2020
	(in thousands)
Balance at January 1, 2020	$	5,010
Additions based on tax positions related to current year	305
Reductions for tax positions of prior years	(428)
Settlements	(196)
Balance at September 30, 2020	$	4,691

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 income tax matters. At this time, management’s best estimate of the reasonably possible change in the amount of gross unrecognized tax benefits is approximately no change to an increase of $1.0 million during the next twelve months, due to the combination of expiration of certain statute of limitations and estimated additions.  The federal statute of limitations remains open for the years 2017 and forward. Tax years 2010 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.

On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Act (the "CARES Act"). The CARES Act is an emergency economic stimulus package in response to the coronavirus outbreak which, among other things, contains numerous income tax provisions. The Company has evaluated the impact of the CARES Act and believes it will not have a material impact on the Company's consolidated financial statements or related disclosures.

Note 13.  Commitments and Contingencies

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

We do not have a significant amount of purchase commitments for tractors (net of tractor sale commitments) and trailer equipment as of September 30, 2020.

Note 14.  Subsequent Events

No events occurred requiring disclosure other than the repurchase of 0.6 million shares of our common stock for $10.8 million subsequent to September 30, 2020.

Overview

We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We operate our consolidated operations under the brand names of Heartland Express and Millis Transfer. We primarily provide nationwide asset-based dry van truckload service for major shippers from Washington to Florida and New England to California. Approximately 99.9% of our operating revenue is derived from shipments within the United States with the remainder being Canada. We do not have any operations in Mexico. 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 and were reduced to serving select dedicated customers in 2019. 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 believe 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 operate in a cyclical industry. General demand for our freight services was strong throughout all of 2018 which resulted in tight freight capacity. During 2019 general demand for freight services was at a level lower than what was experienced throughout most of 2018. Further, 2020 has presented unique operating challenges with a volatile freight market, changing

14

customer needs and relationships, and an uncertain economic landscape in the months ahead. From early 2019 through the first quarter of 2020, demand was modest and supply was excessive except for a few weeks in March, when inventory restocking in response to COVID-19 created a stronger environment. In the second quarter of 2020, the relationship between supply and demand worsened through early May before becoming progressively more favorable to us, leading to an upswing in our volumes, equipment utilization, and average freight rates through the end of the third quarter of 2020. Given the impacts of COVID-19 on the economy currently and the potential impacts in the months ahead, it is unclear at this time how freight demand will respond over the next several months. In addition to freight and driver markets, we are impacted by fluctuations in markets for used tractors and trailers, fuel, and insurance coverage. We believe our strong balance sheet, modern fleet, tractor depreciation policy, safety record, and fuel surcharge programs position us well to withstand or capitalize on fluctuations in these markets.

We continue to focus on providing quality service to targeted customers with a high density of freight in our regional operating areas. Organic growth has become increasingly difficult for traditional over-the-road truckload services given a shortage of qualified drivers in the industry. We continue to evaluate and explore different driving options and offerings for our existing and potential new drivers.

In addition to organic growth through the development of our regional operating areas, we have completed eight acquisitions since 1986 with the most recent and our third acquisition within the last seven years, Millis Transfer, occurring on August 26, 2019.  These eight acquisitions have enabled us to solidify our position within existing regions, expand into new operating regions, and pursue new customer relationships in new markets. We are highly selective about acquisitions, with our main criteria being (i) safe operations, (ii) high quality professional truck drivers, (iii) fleet profile that is compatible with our philosophy or can be replaced economically, and (iv) freight profile that will allow a path to a low-80s operating ratio upon full integration, application of our cost structure, and freight optimization, including exiting certain loads that fail to meet our operating profile. We expect to continue to evaluate acquisition candidates presented to us. We believe 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.

Competition for drivers has historically been intense and we expect attracting and retaining qualified drivers will be an ongoing and volatile challenge. COVID-19 safety measures have limited the amount of potential drivers we can bring into our operating locations for required orientation prior to being hired. We do not currently know how long this will last. We continue to explore new strategies to attract and retain qualified drivers. We hire the majority of our drivers with at least six 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 and benefits 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. In response to current hiring and retention challenges in our industry we evaluated our pay packages and made an increase to driver compensation in November 2020. We believe that our driver compensation and benefits 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.

On August 26, 2019 we completed our third acquisition in seven years. We acquired all the outstanding equity of Midwest Holdings, Inc. and Millis Real Estate LLC (collectively “Millis Transfer”).  The Millis Transfer acquisition added additional dry van truckload capacity to our core operations.   They have operated a driver training school program for over 20 years and through this program, potential drivers are taught the driving skills and core safety procedures required to obtain a commercial drivers license.  The driver training school program offers an additional opportunity to hire professional drivers other than the traditional approach of hiring only experienced over-the-road drivers.  Millis Transfer has driver compensation and benefit packages similar to Heartland including a driver pay structure that rewards drivers for safety and longevity.   

As one of our highest expense categories, managing fuel cost continues to be one of management's top priorities. Recent global events has created volatility in energy markets. Average DOE diesel fuel prices per gallon for the three months ended September 30, 2020 and 2019 were $2.43 and $3.02, respectively. The 2020 average price per gallon through October 26, 2020, was $2.56. We cannot predict what fuel prices will be for the remainder of 2020. 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 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, controlling out-of-route miles, controlling empty miles, utilizing on-board

15

diesel and battery power units to minimize idling, educating drivers to save energy, trailer skirting and rear fairings, and increasing fuel economy through the purchase of newer, more fuel-efficient tractors. At September 30, 2020, the Company’s tractor fleet had an average age of 2.0 years and the Company's trailer fleet had an average age of 3.6 years.

We ended the first nine months of 2020 with operating revenues of $489.5 million, including fuel surcharges, net income of $53.1 million, and basic net income per share of $0.65 on basic weighted average outstanding shares of 81.5 million compared to operating revenues of $429.6 million, including fuel surcharges, net income of $60.2 million, and basic net income per share of $0.73 on basic weighted average shares of 82.0 million in the first nine months of 2019. We posted an 85.8% operating ratio (operating expenses as a percentage of operating revenues) for the nine months ended September 30, 2020 compared to 82.2% for the same period of 2019. We posted a 84.2% non-GAAP adjusted operating ratio(1) (operating expenses as a percentage of operating revenues, net of fuel surcharge) for the nine months ended September 30, 2020 compared to 79.6% for the same period of 2019. We had total assets of $959.8 million at September 30, 2020. We achieved a return on assets of 7.1% and a return on equity of 9.4% over the immediate past four quarters ended September 30, 2020, compared to 9.6% and 12.8%, respectively, for the immediate past four quarters ended September 30, 2019.  

Our cash flow from operating activities for the nine months ended September 30, 2020 of $133.0 million was 27.2% of operating revenues, compared to $109.4 million and 25.5% in the same period of 2019.  During 2020, our net investing cash flows used were $112.3 million, which was the result of net purchases of revenue equipment and property improvements. We used $17.6 million in financing activities primarily related to the repurchase of stock ($12.3 million) and the payment of dividends ($4.9 million). As a result, our cash, cash equivalents and restricted cash increased $3.1 million during the nine months ended September 30, 2020.  We ended the third quarter of 2020 with cash, cash equivalents and restricted cash of $99.2 million. Cash and cash equivalents, excluding restricted cash was $81.9 million at September 30, 2020.

Adjusted operating ratio	81.5%		79.4%		84.2%		79.6%

(a) Adjusted operating ratio as reported in this Form 10-Q is based upon operating expenses, net of fuel surcharge revenue, as a percentage of operating revenue excluding fuel surcharge revenue. We believe that adjusted operating ratio is more representative of our underlying operations by excluding the volatility of fuel prices, which we cannot control. Adjusted operating ratio is not a substitute for operating ratio measured in accordance with GAAP. There are limitations to using non-GAAP financial measures. Although we believe that adjusted operating ratio improves comparability in analyzing our period-to-period performance, it could limit comparability to other companies in our industry if those companies define adjusted operating ratio differently. Because of these limitations, adjusted operating ratio should not be considered a measure of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management

16

compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.

Three Months Ended September 30, 2020 Compared With the Three Months Ended September 30, 2019

The Company acquired Millis Transfer on August 26, 2019 and therefore the operating results of the Company for the three months ended September 30, 2020 includes the operating results of Millis Transfer while the comparative period ended September 30, 2019 includes Millis Transfer operations for the period of August 26, 2019 through September 30, 2019. Millis Transfer's operations for this period impacted the change in operating revenues, salaries, wages and benefits, fuel expense, and depreciation and amortization in the three months ended September 30, 2020 compared to 2019 as further explained below.

Our quarterly operating ratio was 83.2% and 81.5% non-GAAP adjusted operating ratio as compared to the prior year 81.9% and 79.4%. See the “GAAP to Non-GAAP Reconciliation Schedule” above for a reconciliation of our non-GAAP adjusted operating ratio. Our net income was $20.7 million for the three months ended September 30, 2020 and $20.5 million during the same period ended September 30, 2019, an increase of 1.0%. The increase in operating ratio is primarily due to lower gains on sale of revenue equipment during the three months ended September 30, 2020 compared to the same period in 2019. The reduction in gains is primarily due to trade activity timing. We expect to record gains on disposal of property and equipment of approximately $4 to $5 million for the fourth quarter of 2020. Consistent with past acquisitions, we continue to implement cost reduction and freight optimization strategies at Millis Transfer focused on improving the consolidated operating ratio.

Operating revenue increased $14.4 million (9.7%), to $162.3 million for the three months ended September 30, 2020 from $147.9 million for the three months ended September 30, 2019.  The increase of $18.4 million (14.2%) in revenue was primarily the result of an increase in total miles due to the addition of Millis, causing an increase in trucking and accessorial and other revenues, partially offset by a fuel surcharge revenue decrease of $4.0 million (21.6%) from $18.4 million in 2019 to $14.4 million in 2020. Operating revenues (the total of trucking and fuel surcharge revenue) are primarily earned based on loaded miles driven in providing truckload services. Our operating revenues are reviewed regularly on a combined basis across the United States due to the similar nature of our services offerings and related similar base pricing structure. The number of

17

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 is directly affected by the number of available drivers providing capacity to us. The overall increase in operating revenue reflects the combined effect of higher miles driven and higher freight rates earned on miles driven.

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 lower average Department of Energy ("DOE") diesel fuel prices (19.7%) during the three months ended September 30, 2020 compared to September 30, 2019, as reported by the DOE, which was partially offset by more loaded miles driven.

Salaries, wages, and benefits increased $6.3 million (10.3%), to $67.2 million for the three months ended September 30, 2020 from $60.9 million in the 2019 period.  Salaries, wages, and benefits increased primarily due to the addition of the Millis Transfer drivers and non-driver employees after the acquisition date. In response to current hiring and retention challenges in our industry we made an increase to driver compensation during the fourth quarter of 2020. The average increase on driver wages is expected to be approximately 6% for legacy Heartland drivers. This is expected to increase total salaries, wages, and benefits expense in the fourth quarter of 2020 as the increase was effective October 31, 2020.

Rent and purchased transportation decreased $0.9 million (48.4%), to $1.0 million for the three months ended September 30, 2020 from $1.9 million in the comparable period of 2019.  The decrease was attributable to a decrease in amounts paid to independent contractors of $0.4 million and a decrease in terminal rent and spotting service costs of $0.5 million. These decreases were due to reductions in leased terminal properties as we ended the leases or acquired the respective terminal facility, and fewer independent contractors. During the quarter ended September 30, 2020, independent contractors accounted for 0.7% of the total fleet miles compared to 1.2% for the same period of 2019.

Fuel decreased $4.0 million (15.8%), to $21.2 million for the three months ended September 30, 2020 from $25.2 million for the same period of 2019. The decrease was primarily due to lower average diesel price per gallon (19.7%) as reported by the DOE, partially offset by increased miles driven. Further, there were general reductions in fuel due to increased fuel economy on our tractor fleet, idle management controls, and operational efficiencies that reduced fuel usage.

Depreciation and amortization increased $2.0 million (8.0%), to $27.6 million during the three months ended September 30, 2020 from $25.6 million in the same period of 2019. The increase is mainly attributable to additional tractor and trailer equipment with the addition of the Millis Transfer fleet.

Operations and maintenance expense increased $0.8 million (13.5%), to $7.1 million during the three months ended September 30, 2020 from $6.3 million in the same period of 2019. The increase is mainly attributable to additional tractor and trailer equipment with the addition of the Millis Transfer fleet.

Operating taxes and licenses expense increased $0.3 million (7.3%), to $3.7 million during the three months ended September 30, 2020 from $3.4 million in 2019. The slight increase was primarily due to increased license and permitting attributable to the addition of the Millis Transfer fleet and terminals.

Insurance and claims expense increased $1.5 million (48.2%), to $4.8 million for the three months ended September 30, 2020 from $3.3 million in 2019, due to increased severity and frequency of claims and increased insurance premiums as compared to the prior year as well as the addition of the Millis fleet. Further, we expect the expense related to insurance premiums over the remainder of 2020 to be higher than the expense recorded for insurance premiums during 2019 and the first quarter of 2020. This is due to the addition of Millis Transfer and increased rates experienced through the insurance renewal process effective April 1, 2020 for our consolidated operations. Effective April 1, 2020, the upper limit of our auto liability insurance coverage was reduced from $100.0 million to $60.0 million. In the future, our insurance and claims expense may be more volatile based upon our reduced aggregate coverage amounts and depending on our future claims experience, which could contribute to earnings volatility.

Other operating expenses increased $0.6 million (10.7%), to $6.6 million, during the three months ended September 30, 2020 from $6.0 million in 2019. These increases are due mainly to increased variable costs associated with additional revenue equipment units in our fleet due to the Millis acquisition, and increased miles driven.

Gains on the disposal of property and equipment decreased $6.9 million (54.6%), to a gain on disposal of $5.7 million during the three months ended September 30, 2020 from $12.6 million gain on disposal in the same period of 2019.  The decrease was primarily due to a significant decrease of equipment sales volume. We expect to record gains on disposal of property and equipment of approximately $4 to $5 million in the fourth quarter of 2020.

18

Our effective tax rate was 24.7% and 25.2% for the three months ended September 30, 2020 and 2019, respectively. The changes in the effective tax rate are driven by favorable prior period adjustments.

Nine Months Ended September 30, 2020 Compared With the Nine Months Ended September 30, 2019

The Company acquired Millis Transfer on August 26, 2019 and therefore the operating results of the Company for the nine months ended September 30, 2020 includes the operating results of Millis Transfer while the comparative period ended September 30, 2019 includes Millis Transfer operations for the period of August 26, 2019 through September 30, 2019. Millis Transfer's operations for this period impacted the change in operating revenues, salaries, wages and benefits, fuel expense, and depreciation and amortization in the nine months ended September 30, 2020 compared to 2019 as further explained below.

Our operating ratio for the nine months ended September 30, 2020 was 85.8% and a non-GAAP adjusted operating ratio of 84.2% as compared to the same period in the prior year at 82.2% and 79.6%, respectively. See the “GAAP to Non-GAAP Reconciliation Schedule” above for a reconciliation of our non-GAAP adjusted operating ratio. Our net income was $53.1 million during the nine months ended September 30, 2020 as compared to $60.2 million during the same period ended September 30, 2019, a decrease of 11.7%. The increase in operating ratio and reduction in income is primarily due to lower gains on sale of revenue equipment during the nine months ended September 30, 2020 compared to the same period in 2019. The reduction in gains is primarily due to trade activity timing. We expect to record gains on disposal of property and equipment of approximately $4 to $5 million in the fourth quarter of 2020.

Operating revenue increased $59.9 million (13.9%), to $489.5 million for the nine months ended September 30, 2020 from $429.6 million for the nine months ended September 30, 2019.  The increase in revenue of $65.5 million (17.4%), was primarily the result of an increase in total miles driven due to the addition of Millis, causing an increase in trucking and accessorial and other revenues, partially offset by a fuel surcharge revenue decrease of $5.6 million (10.5%), from $53.5 million in 2019 to $47.9 million in 2020. Operating revenues (the total of trucking and fuel surcharge revenue) are primarily earned based on loaded miles driven in providing truckload services. Our operating revenues are reviewed regularly on a combined basis across the United States due to the similar nature of our services offerings and related similar base pricing structure. 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 is directly affected by the number of available drivers providing capacity to us. The overall increase in operating revenue reflects the combined effect of higher miles driven partially offset by lower freight rates earned on miles driven.

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 lower average Department of Energy ("DOE") diesel fuel prices (15.6%) as reported by the DOE partially offset by increased miles driven during the nine months ended September 30, 2020 compared to September 30, 2019.

Salaries, wages, and benefits increased $37.5 million (22.3%), to $205.6 million for the nine months ended September 30, 2020 from $168.1 million in the 2019 period.  Salaries, wages, and benefits increased primarily due to the addition of the Millis Transfer drivers and non-driver employees after the acquisition date.

Rent and purchased transportation decreased $2.6 million (41.5%), to $3.6 million for the nine months ended September 30, 2020 from $6.2 million in the comparable period of 2019.  The decrease was attributable to a decrease in amounts paid for revenue equipment lease expense of $0.3 million, a decrease in amounts paid to independent contractors of $1.3 million, and a decrease in terminal rent and spotting service costs of $1.0 million. These decreases were due to reductions in leased revenue equipment and leased terminal locations as we ended the leases and acquired certain terminal locations, and fewer independent contractors. During the nine months ended September 30, 2020, independent contractors accounted for 0.7% of the total fleet miles compared to 1.3% for the same period of 2019.

Fuel decreased $6.3 million (8.8%), to $65.4 million for the nine months ended September 30, 2020 from $71.7 million for the same period of 2019. The decrease was primarily due to lower average diesel price per gallon (15.6%) as reported by the DOE, partially offset by increased miles driven. Further, there were general reductions in fuel due to increased fuel economy on our tractor fleet, idle management controls, and operational efficiencies that reduced fuel usage.

Depreciation and amortization increased $11.0 million (15.6%), to $81.4 million during the nine months ended September 30, 2020 from $70.4 million in the same period of 2019. The increase is mainly attributable to the increase from the addition of the Millis Transfer fleet.

19

Operations and maintenance expense increased $3.8 million (21.4%), to $21.5 million during the nine months ended September 30, 2020 from $17.7 million in the same period of 2019. The increase is mainly attributable to the addition of the Millis Transfer fleet along with additional miles driven.

Operating taxes and licenses expense increased $0.4 million (3.9%), to $11.2 million during the nine months ended September 30, 2020 from $10.8 million in 2019. The increase was primarily due to increased license and permitting costs attributable to the Millis Transfer fleet and terminals.

Insurance and claims expense increased $4.0 million (33.3%), to $16.0 million for the nine months ended September 30, 2020 from $12.0 million in 2019, due to increased severity and frequency of claims and increased insurance premiums as compared to the prior year as well as additional claims resulting from the Millis fleet.

Other operating expenses increased $3.2 million (19.8%), to $19.6 million, during the nine months ended September 30, 2020 from $16.4 million in 2019. These increases are due mainly to increased variable costs associated with additional revenue equipment units in our fleet and increased miles driven.

Gains on the disposal of property and equipment decreased $15.3 million (64.0%), to a gain on disposal of $8.7 million during the nine months ended September 30, 2020 from $24.0 million gain on disposal in the same period of 2019.  The decrease was primarily due to a significant decrease in the number of units sold during the first nine months of 2020.

Our effective tax rates were consistent at 24.5% and 24.5% for the nine months ended September 30, 2020 and 2019, respectively.

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 our primary source of liquidity, cash flow provided by operating activities and proceeds from sales of used equipment. We entered into a line of credit during the fourth quarter of 2013, as amended on August 31, 2018, described below, to partially finance an acquisition in 2013, including the payoff of debt we assumed. After the original debt borrowings were paid off, following the 2013 acquisition, we have not had any debt borrowings on this line of credit. At September 30, 2020, we had $81.9 million in cash and cash equivalents, no outstanding debt, and $88.5 million available borrowing capacity on the Credit Agreement.

In November 2013, Heartland Express, Inc. of Iowa, (the "Borrower"), a wholly owned subsidiary of the Company, 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 original commitment decreased to $175.0 million on November 1, 2016 through scheduled maturity on October 31, 2018. However, on August 31, 2018, Borrower and the Bank entered into the First Amendment to this Credit Agreement. The First Amendment (i) provides for a $100.0 million unsecured revolving line of credit (the “Revolver”), which may be used for working capital, equipment financing, permitted acquisitions, and general corporate purposes, (ii) provides an uncommitted accordion feature, which allows the Company a one-time request, at the discretion of the Bank, to increase the Revolver by up to an additional $100.0 million, (iii) increases the letter of credit subfeature of the Credit Agreement from $20 million to $30 million, and (iv) extends the maturity of the Credit Agreement to August 31, 2021, subject to the Borrower’s ability to terminate the commitment at any time at no additional cost to the Borrower.

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. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus a spread between 0.700% and 0.900%, based on the Company's consolidated funded debt to adjusted EBITDA ratio or (ii) Prime (Index) plus 0.0%. There is a commitment fee on the unused portion of the Revolver between 0.0725% and 0.1750%, based on the Company's consolidated funded debt to adjusted EBITDA ratio.

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 $250.0 million requirement, measured quarterly, and (iv) limitations on certain 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 September 30, 2020 and during the three and nine months then ended.

20

Cash flow provided by operating activities during the nine months ended September 30, 2020 was $133.0 million as compared to $109.4 million during the same period of 2019.  This was primarily due to the net effect of $30.1 million more cash provided by non-working capital items and $0.5 million less cash used by working capital items partially offset by a $7.0 million decrease due to lower net income. Cash flows provided by operating activities was 27.2% of operating revenues for the nine months ended September 30, 2020 compared with 25.5% for the same period of 2019. The CARES Act allows employers to defer the deposit and payment of the employer's share of Social Security taxes. As a result we have deferred remitting payroll taxes normally paid on a weekly basis until the end of 2021 when the first half of the deferred tax payments are due and 2022 when the second half of the deferred tax payments are due. The CARES Act deferred federal payroll taxes as of September 30, 2020 was $6.0 million.

Cash used in investing activities was $112.3 million during the nine months ended September 30, 2020 compared to cash flows used in investing activities of $116.3 million during the comparative 2019 period, or a decrease in cash used of $4.0 million. The net decrease in cash used was the result of less property and equipment purchases net of proceeds of $58.2 million, offset by $62.1 million used in the acquisition of Millis in 2019. We did not have a similar acquisition during 2020. We expect to spend approximately $6 to $9 million in net capital expenditures during the remainder of 2020.

Cash used in financing activities decreased $27.6 million during the nine months ended September 30, 2020 compared to the same period of 2019 due mainly to $39.9 million less repayments on acquired debt, after the Millis acquisition. This was partially offset by $12.3 million more cash used for repurchases of common stock during the nine months ended September 30, 2020 as we repurchased 0.7 million shares compared to zero share repurchases during the same period of 2019.

We have a stock repurchase program with 6.2 million shares remaining authorized for repurchase under the program as of September 30, 2020 and the program has no expiration date. There were no shares repurchased in the open market during the three months ended September 30, 2020 and 2019 respectively. There were 0.7 million shares repurchased in the open market for $12.3 million during the nine months ended September 30, 2020 and no shares repurchased during the nine months ended September 30, 2019. 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 repurchased additional shares subsequent to the end of the quarter during October 2020. We repurchased 0.6 million shares of our common stock for $10.8 million subsequent to September 30, 2020.

We had net payments of $4.6 million and $12.8 million for income taxes, net of refunds, in the nine months ended September 30, 2020 and September 30, 2019, respectively. The decline in net payments is due to a federal refund received during 2020, as well as increased net purchases of property and equipment, that qualified for additional tax deductions resulting in a reduction in estimated tax payments.

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.  

Off-Balance Sheet Transactions

Our liquidity or financial condition is not materially affected by off-balance sheet transactions.

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

21

We had no debt outstanding at September 30, 2020 although we had $88.5 million available borrowing capacity on our Credit Agreement at September 30, 2020. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus a spread between 0.700% and 0.900%, based on the Company's consolidated funded debt to adjusted EBITDA ratio or (ii) Prime (Index) plus 0.0%. 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 tires (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. Additionally, because our fuel surcharge recovery lags behind changes in fuel prices, our fuel surcharge recovery may not capture the increased costs we pay for fuel, especially when prices are rising. Based on our actual fuel purchases for 2019, assuming miles driven, fuel surcharges as a percentage of revenue, percentage of empty and out-of-route miles, and miles per gallon remained consistent with 2019 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 $7.2 million in 2020. 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 2020, a 10% increase in the price of tires would increase our tire purchase expense by $1.3 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. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2020.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures, or our internal controls, will prevent all errors or intentional fraud. An internal control system, no matter how well-conceived and operated, can only provide reasonable, not total, assurance that the objectives of such internal controls are met.

Changes in Internal Control Over Financial Reporting – During the third quarter of 2020, we finalized implementation of internal controls following the acquisition of Millis Transfer, with the controls operating effectively through September 30, 2020. The Millis Transfer controls are now subject to our ongoing internal control testing regimen and are part of our conclusion that internal controls are operating effectively as of September 30, 2020. There have been no other changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

ITEM 1. LEGAL PROCEEDINGS

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. Based on our present knowledge, management believes that the resolution of open claims and pending litigation is not likely to have a materially adverse effect on our consolidated financial statements.

While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present. Our Annual Report on Form 10-K for the year ended December 31, 2019, as amended, and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020, in the sections entitled "Item 1A. Risk Factors," describe some of the risks and uncertainties associated with our business.

Basis of Presentation and New Accounting Pronouncements

Heartland Express, Inc. 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., Midwest Holding Group, LLC and Millis Transfer, LLC. On August 26, 2019, Heartland Express, Inc. of Iowa acquired Midwest Holding Group, Inc. and Millis Real Estate Leasing, LLC (together, "Millis Transfer"), a truckload carrier headquartered in Black River Falls, Wisconsin. Effective December 31, 2019, Millis Transfer, Inc. and Midwest Holding Group, Inc. were converted to Millis Transfer, LLC and Midwest Holding Group, LLC, respectively. Further, effective December 31, 2019, Millis Real Estate Leasing, LLC, Rivera Real Estate, LLC, and Great River Leasing, LLC were merged into Millis Transfer, LLC. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We primarily provide nationwide asset-based dry van truckload service for major shippers from major shippers across the United States.

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned. The consolidated financial results for the three and nine months ended September 30, 2020 include the results of Millis Transfer while the three and nine months ended September 30, 2019 include Millis Transfer only for the period of August 26, 2019 through September 30, 2019. 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. GAAP 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, 2019 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission (the "SEC") on February 25, 2020, as amended on July 21, 2020. 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 nine month period ended September 30, 2020.

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. We have adopted this standard effective January 1, 2020 and the impact of adoption of the standard did not have a material impact on our financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): "Simplifying the Accounting for Income Taxes". The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also clarifies and amends existing guidance to improve consistent application among reporting entities. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within that reporting period; however, early adoption is permitted. We expect to adopt in the period beginning January 1, 2021 and expect the impact to be immaterial to our financial statements.

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 nine months ended September 30, 2020.

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 to select dedicated customers, which are not significant to our operations. 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.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue Recognition

The Company recognizes revenue over time as control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. The delivery of the shipment and completion of the performance obligation allows for the collection of payment generally within 30 days after the delivery date of the shipment for the majority of our customers.

The Company's operations are consistent with those in the trucking industry where freight is hauled twenty-four hours a day and seven days a week, subject to hours of service rules. The Company’s average length of haul is 400-500 miles per trip and each individual shipment accepted by the Company is considered a separate contract with the performance obligation being the delivery of the freight. Our average length of haul for each load of freight generally equals less than one day of continuous transit time. The Company estimates revenue for multiple-stop loads based on miles run and estimates revenue for single stop loads based on transit time, as the customer simultaneously receives and consumes the benefit provided. The Company hauls freight and earns revenue on a consistent basis throughout the periods presented. A corresponding contract asset existed for the estimated revenue of these in-process loads for $1.1 million and $1.2 million at September 30, 2020 and December 31, 2019, respectively. Recorded contract assets are included in the accounts receivable line item of the balance sheet. Corresponding liabilities are recorded in the accounts payable and accrued liabilities and compensation and benefits line items for the estimated expenses on these same in-process loads. The Company had no contract liabilities associated with our operations as of September 30, 2020 and December 31, 2019, respectively.

Total revenues recorded were $162.3 million and $147.9 million for the three months ended September 30, 2020 and 2019, respectively. Fuel surcharge revenues were $14.4 million and $18.4 million for the three months ended September 30, 2020 and 2019, respectively. Accessorial and other revenues recorded in the consolidated statements of comprehensive income collectively represented $3.6 million and $3.5 million for the three months ended September 30, 2020 and 2019, respectively.

Total revenues recorded were $489.5 million and $429.6 million for the nine months ended September 30, 2020 and 2019, respectively. Fuel surcharge revenues were $47.9 million and $53.5 million for the nine months ended September 30, 2020 and 2019, respectively. Accessorial and other revenues recorded in the consolidated statements of comprehensive income collectively represented $10.5 million and $9.1 million for the nine months ended September 30, 2020 and 2019, respectively.

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 new 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. At September 30, 2020, there were $5.2 million amounts receivable related to equipment sales recorded in other current assets compared to $1.3 million at December 31, 2019.

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 made available up to 0.9 million shares for the purpose of making restricted stock grants to our eligible officers and employees. There were no shares that were issued during the period 2011 to 2016 that remain unvested at September 30, 2020. Shares granted in 2017 through 2020 have various vesting terms that range from immediate to four years from the date of grant. Compensation expense associated with these awards is based on the market value of our stock on the grant date. Compensation expense associated with restricted stock awards is included in salaries, wages and benefits in the consolidated statements of comprehensive income. There were no significant assumptions made in determining fair value. Compensation expense associated with restricted stock awards was $0.2 million and $1.5 million respectively, for the three and nine months ended September 30, 2020. Compensation expense associated with restricted stock awards was $0.3 million and $1.6 million respectively, for the three and nine months ended September 30, 2019. Unrecognized compensation expense was $0.3 million at September 30, 2020 which will be recognized over a weighted average period of 0.7 years.

Long-term Line of Credit [Abstract]

Long-Term Debt

Long-Term Debt

In November 2013, Heartland Express, Inc. of Iowa, (the "Borrower"), a wholly owned subsidiary of the Company, 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 original commitment decreased to $175.0 million on November 1, 2016 through scheduled maturity on October 31, 2018. However, on August 31, 2018, Borrower and the Bank entered into the First Amendment to this Credit Agreement. The First Amendment (i) provides for a $100.0 million unsecured revolving line of credit (the “Revolver”), which may be used for working capital, equipment financing, permitted acquisitions, and general corporate purposes, (ii) provides an uncommitted accordion feature, which allows the Company a one-time request, at the discretion of the Bank, to increase the Revolver by up to an additional $100.0 million, (iii) increases the letter of credit subfeature of the Credit Agreement from $20.0 million to $30.0 million, and (iv) extends the maturity of the Credit Agreement to August 31, 2021, subject to the Borrower’s ability to terminate the commitment at any time at no additional cost to the Borrower.

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. Borrowings under the Credit Agreement can either be, at Borrower's election, (i) one-month or three-month LIBOR (Index) plus a spread between 0.700% and 0.900%, based on the Company's consolidated funded debt to adjusted EBITDA ratio or (ii) Prime (Index) plus 0.0%. There is a commitment fee on the unused portion of the Revolver between 0.0725% and 0.1750%, based on the Company's consolidated funded debt to adjusted EBITDA ratio.

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 $250.0 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 September 30, 2020 and during the nine months then ended.We had zero outstanding debt at September 30, 2020 and December 31, 2019, respectively. Outstanding letters of credit associated with the revolving line of credit at September 30, 2020 were $11.5 million. As of September 30, 2020, the line of credit available for future borrowing was $88.5 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 effect of changes 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 September 30, 2020 and December 31, 2019. Our effective tax rate was 24.7% and 25.2% for the three months ended September 30, 2020 and 2019, respectively. The change in the effective tax rate is primarily the result of a favorable prior period provision to actual adjustment. Our effective tax rate was 24.5% and 24.5% for the nine months ended September 30, 2020 and 2019, 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 September 30, 2020 and December 31, 2019, we had a total of $4.7 million and $5.0 million in gross unrecognized tax benefits, respectively included in long-term income taxes payable in the consolidated balance sheet. Of this amount, $3.7 million and $4.0 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of September 30, 2020 and December 31, 2019. The net change in unrecognized tax benefits was a decrease of $0.2 million and a decrease of $0.1 million during the three months ended September 30, 2020 and September 30, 2019, respectively. The net decrease in unrecognized tax benefits during the three months ended September 30, 2020 was due to settlements with corresponding reductions to uncertain tax liabilities net of additions. The net change in unrecognized tax benefits was a decrease of $0.3 million and an increase of $0.3 million during the nine months ended September 30, 2020 and September 30, 2019, respectively. The net decrease in unrecognized tax benefits during the nine months ended September 2020 was mainly due to the expiration of certain statutes of limitation net of additions. This change had the corresponding increasing or decreasing impact on the effective state tax rate during the respective periods. The total net amount of accrued interest and penalties for such unrecognized tax benefits was $0.8 million and $0.9 million at September 30, 2020 and December 31, 2019, respectively 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 September 30, 2020 and September 30, 2019 was a net expense of approximately zero and $0.1 million, respectively. The favorable impact for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was due to the accrual reductions for interest and penalties in excess of settlements. Net interest and penalties included in income tax expense for the nine month period ended September 30, 2020 and September 30, 2019 was a net benefit of approximately $0.1 million and $0.1 million, respectively. The favorable impact for the nine month period ended September 30, 2020 to income tax expense was 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:

	2020
	(in thousands)
Balance at January 1, 2020	$	5,010
Additions based on tax positions related to current year	305
Reductions for tax positions of prior years	(428)
Settlements	(196)
Balance at September 30, 2020	$	4,691

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 income tax matters. At this time, management’s best estimate of the reasonably possible change in the amount of gross unrecognized tax benefits is approximately no change to an increase of $1.0 million during the next twelve months, due to the combination of expiration of certain statute of limitations and estimated additions.  The federal statute of limitations remains open for the years 2017 and forward. Tax years 2010 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.

On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Act (the "CARES Act"). The CARES Act is an emergency economic stimulus package in response to the coronavirus outbreak which, among other things, contains numerous income tax provisions. The Company has evaluated the impact of the CARES Act and believes it will not have a material impact on the Company's consolidated financial statements or related disclosures.

On August 26, 2019, Heartland Express, Inc. of Iowa acquired Midwest Holding Group, Inc. and Millis Real Estate Leasing, LLC (together, "Millis Transfer"), a truckload carrier headquartered in Black River Falls, Wisconsin. Effective December 31, 2019, Millis Transfer, Inc. and Midwest Holding Group, Inc. were converted to Millis Transfer, LLC and Midwest Holding Group, LLC, respectively. Further, effective December 31, 2019, Millis Real Estate Leasing, LLC, Rivera Real Estate, LLC, and Great River Leasing, LLC were merged into Millis Transfer, LLC. We, together with our subsidiaries, are a short-to-medium haul truckload carrier (predominately 500 miles or less per load). We primarily provide nationwide asset-based dry van truckload service for major shippers from major shippers across the United States.The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned. The consolidated financial results for the three and nine months ended September 30, 2020 include the results of Millis Transfer while the three and nine months ended September 30, 2019 include Millis Transfer only for the period of August 26, 2019 through September 30, 2019. 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. GAAP 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, 2019 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission (the "SEC") on February 25, 2020, as amended on July 21, 2020. 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 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. We have adopted this standard effective January 1, 2020 and the impact of adoption of the standard did not have a material impact on our financial statements.In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): "Simplifying the Accounting for Income Taxes". The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also clarifies and amends existing guidance to improve consistent application among reporting entities. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within that reporting period; however, early adoption is permitted. We expect to adopt in the period beginning January 1, 2021 and expect the impact to be immaterial to our financial statements.
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 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 to select dedicated customers, which are not significant to our operations. 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.
Revenue [Policy Text Block]	The Company recognizes revenue over time as control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. The delivery of the shipment and completion of the performance obligation allows for the collection of payment generally within 30 days after the delivery date of the shipment for the majority of our customers. The Company's operations are consistent with those in the trucking industry where freight is hauled twenty-four hours a day and seven days a week, subject to hours of service rules. The Company’s average length of haul is 400-500 miles per trip and each individual shipment accepted by the Company is considered a separate contract with the performance obligation being the delivery of the freight. Our average length of haul for each load of freight generally equals less than one day of continuous transit time. The Company estimates revenue for multiple-stop loads based on miles run and estimates revenue for single stop loads based on transit time, as the customer simultaneously receives and consumes the benefit provided. The Company hauls freight and earns revenue on a consistent basis throughout the periods presented.
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 new 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 TaxesWe 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 effect of changes 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 EventsNo events occurred requiring disclosure other than the repurchase of 0.6 million shares of our common stock for $10.8 million subsequent to September 30, 2020.
