Roadrunner Transportation Systems, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

1. Organization, Nature of Business and Significant Accounting Policies

Nature of Business

Roadrunner Transportation Systems, Inc. (the “Company”) is headquartered in Cudahy, Wisconsin and has the following three operating segments: truckload logistics (“TL”), less-than-truckload (“LTL”), and transportation management solutions (“TMS”). Within its TL business, the Company operates a network of 34 TL service centers, five freight consolidation and inventory management centers, and 26 company dispatch offices and is augmented by 128 independent brokerage agents. Within its LTL business, the Company operates 45 LTL service centers throughout the United States, complemented by relationships with over 200 delivery agents. Within its TMS business, the Company operates from ten service centers and nine dispatch offices throughout the United States. From pickup to delivery, the Company leverages relationships with a diverse group of third-party carriers to provide scalable capacity and reliable, customized service, including domestic and international air and ocean transportation services, to its customers. The Company operates primarily in the United States.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Segment Reporting

The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments, which are also its reportable segments: TL, LTL, and TMS.

2. Acquisitions

On April 30, 2013, the Company acquired all of the outstanding capital stock and the Charleston, South Carolina property of Wando Trucking, Inc.

Palmer") for the purpose of expanding its current market presence in the TL segment. Cash consideration paid was $2.5 million. The acquisition was financed with borrowings under the Company's credit facility discussed in Note 5. The G.W. Palmer purchase agreement calls for contingent consideration in the form of an earnout capped at $2.8 million. The former owners of G.W. Palmer are entitled to receive an initial payment, not to exceed $0.7 million, for achieving operating income before amortization, as defined in the purchase agreement, in excess of $0.9 million for the period from the closing date through December 31, 2013, and a payment equal to the amount by which G.W.

The acquisitions of Wando Trucking, Adrian Carriers, Marisol, TA Drayage, G.W Palmer, and YES Trans (collectively, "2013 acquisitions") are considered individually immaterial, but material in the aggregate. The acquisitions of Rich Logistics and Unitrans (collectively, "2014 acquisitions") are considered individually immaterial, but material in the aggregate. The following table summarizes, in the aggregate, the allocation of the purchase price paid to the fair value of the net assets for the 2013 and 2014 acquisitions (in thousands):

	2014 Acquisitions			2013 Acquisitions
Accounts receivable	$	26,107		$	22,666
Other current assets	2,264			922
Property and equipment	17,217			14,392
Goodwill	53,812			78,646
Customer relationship intangible assets	20,894			19,727
Other noncurrent assets	242			12
Accounts payable and other liabilities	(19,726		)	(35,717		)
Total	$	100,810		$	100,648

The goodwill for the acquisitions, in the aggregate, is a result of acquiring and retaining the existing workforces and expected synergies from integrating the operations into the Company. Goodwill of $2.0 million associated with the asset purchases will be deductible for tax purposes while the remaining goodwill will not be deductible for tax purposes. Purchase accounting is considered final for 2013 acquisitions of Wando and Adrian. Purchase accounting is considered preliminary for the 2013 acquisitions of Marisol, TA Drayage, G.W. Palmer, and YES Trans with respect to deferred taxes and revenue recognition. Purchase accounting is considered preliminary for the 2014 acquisitions as final information was not available as of June 30, 2014.

The supplemental unaudited pro forma financial information above is presented for informational purposes only. It is not necessarily indicative of what the Company's financial position or results of operations actually would have been had the Company completed the acquisitions at the dates indicated, nor is it intended to project the future financial position or operating results of the combined company.

3. Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price of all acquisitions over the estimated fair value of the net assets acquired. The Company performs an impairment test of goodwill annually as of July 1. The 2013 impairment test did not result in any impairment losses. There is no goodwill impairment for any of the periods presented in the Company's condensed consolidated financial statements.

The following is a rollforward of goodwill from December 31, 2013 to June 30, 2014 by reportable segment (in thousands):

	TL		LTL		TMS		Total
Goodwill balance as of December 31, 2013	$	211,413	$	197,312	$	110,018	$	518,743
Goodwill related to acquisitions	15,997		—		37,815		53,812
Goodwill balance as of June 30, 2014	$	227,410	$	197,312	$	147,833	$	572,555

Intangible assets consist of customer relationships acquired from business acquisitions. Intangible assets as of June 30, 2014 and December 31, 2013 were as follows (in thousands):

	June 30, 2014							December 31, 2013
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Value		Gross Carrying Amount		Accumulated Amortization			Net Carrying Value
TL	$	25,426	$	(6,240	)	$	19,186	$	17,826	$	(5,294	)	$	12,532
LTL	1,358		(837		)	521		1,358		(723		)	635
TMS	32,815		(2,228		)	30,587		19,522		(1,326		)	18,196
Total	$	59,599	$	(9,305	)	$	50,294	$	38,706	$	(7,343	)	$	31,363

6

Customer relationships intangible assets are amortized over their estimated five to ten years useful lives. Amortization expense was $1.0 million and $0.5 million for the three months ended June 30, 2014 and 2013, respectively, and $1.9 million and $1.1 million for the six months ended June 30, 2014 and 2013, respectively. Estimated amortization expense for each of the next five years based on intangible assets as of June 30, 2014 is as follows (in thousands):

Remainder 2014	$	2,994
2015	5,916
2016	5,824
2017	5,703
2018	5,439
2019	5,136
Thereafter	19,282
Total	$	50,294

4. Fair Value Measurement

Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1 — Quoted market prices in active markets for identical assets or liabilities.

Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3 — Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.

A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

The following table presents information, as of June 30, 2014 and December 31, 2013, about the Company’s financial liabilities. Contingent purchase price related to acquisitions is measured at fair value on a recurring basis, according to the valuation techniques the Company used to determine fair value (in thousands):

	June 30, 2014
	Level 1		Level 2		Level 3		Fair Value
Contingent purchase price related to acquisitions	$	—	$	—	$	11,726	$	11,726
Total liabilities at fair value	$	—	$	—	$	11,726	$	11,726

	December 31, 2013
	Level 1		Level 2		Level 3		Fair Value
Contingent purchase price related to acquisitions	$	—	$	—	$	17,054	$	17,054
Total liabilities at fair value	$	—	$	—	$	17,054	$	17,054

In measuring the fair value of the contingent purchase price liability, the Company used an income approach that considers the expected future earnings of the acquired businesses and the resulting contingent payments, discounted at a risk-adjusted rate.

The table below sets forth a reconciliation of the Company’s beginning and ending Level 3 financial liability balance for the three and six months ended June 30, 2014 and 2013 and the year ended December 31, 2013 (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,						Year Ended December 31,
	2014			2013			2014			2013			2013
Balance, beginning of period	$	17,249		$	21,613		$	17,054		$	20,907		$	20,907
Earnouts related to acquisitions	—			5,348			—			5,778			4,288
Payments of contingent purchase obligations	(4,804		)	(2,407		)	(4,804		)	(2,407		)	(2,407		)

5. Long-Term Debt

Long-term debt as of June 30, 2014 and December 31, 2013 consisted of the following (in thousands):

	June 30, 2014			December 31, 2013
Senior debt:
Revolving credit facility	$	144,864		$	22,015
Term loan	166,250			170,625

Less: Current maturities	(13,125		)	(10,938		)
Total long-term debt, net of current maturities	$	297,989		$	181,702

On August 3, 2012, the Company entered into a third amended and restated credit agreement with U.S. Bank National Association (“U.S. Bank”) and other lenders, which increased the revolving credit facility from $100.0 million to $125.0 million and the term loan from $140.0 million to $170.0 million. On August 9, 2013, the Company entered into a fourth amended and restated credit agreement (the "credit agreement") with U.S. Bank and other lenders, which increased the revolving credit facility to $200.0 million and the term loan to $175.0 million. The credit facility matures on August 9, 2018. Principal on the term loan is due in quarterly installments of $2.2 million per quarter through June 30, 2014. As of September 30, 2014, quarterly principal payments on the term loan increase to $3.3 million through June 30, 2016 and increase to $4.4 million beginning September 30, 2016 through June 30, 2018. Any remaining outstanding balance under the credit agreement is due August 9, 2018. The Company categorizes the borrowings under the credit agreement as Level 2 in the fair value hierarchy as defined in Note 4. The carrying value of the Company's long-term debt approximates fair value as the debt agreement bears interest based on prevailing variable market rates currently available. The credit agreement is collateralized by all assets of the Company and contains certain financial covenants, including a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. Additionally, the credit agreement contains negative covenants limiting, among other things, additional indebtedness, capital expenditures, transactions with affiliates, additional liens, sales of assets, dividends, investments, advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. As of and during the three and six months ended June 30, 2014, the Company was in compliance with all covenants contained in the credit agreement. Borrowings under the credit agreement bear interest at either (a) the Eurocurrency Rate (as defined in the credit agreement), plus an applicable margin in the range of 2.0% to 3.3%, or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.3%. The revolving credit facility also provides for the issuance of up to $30.0 million in letters of credit. As of June 30, 2014, the Company had outstanding letters of credit totaling $16.0 million. As of June 30, 2014, total availability under the revolving credit facility was $39.1 million and the average interest rate on the credit agreement was 3.4%.

7. Earnings Per Share

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of common stock outstanding during the period. For the three and six months ended June 30, 2014 and 2013, diluted earnings per share was calculated by dividing net income available to common stockholders by the weighted average common stock outstanding plus stock equivalents that would arise from the assumed exercise of stock options, the conversion of warrants, and the delivery of stock underlying restricted stock units using the treasury stock method. There is no difference, for any of the periods presented, in the amount of net income available to common stockholders used in the computation of basic and diluted earnings per share.

As of June 30, 2014, all stock options, warrants, and restricted stock units were included in the computation of diluted earnings per share. The following table reconciles basic weighted average stock outstanding to diluted weighted average stock outstanding for the three and six months ended June 30, 2014 and 2013 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2014	2013	2014	2013
Basic weighted average stock outstanding	37,868	35,585	37,779	35,289
Effect of dilutive securities
Employee stock options	180	465	201	477
Warrants (1)	1,238	1,214	1,220	1,245
Restricted stock units	44	43	54	40
Diluted weighted average stock outstanding	39,330	37,307	39,254	37,051

(1) For the six months ended June 30, 2013, the warrants increased by 609 from the amount previously reported to correct an error. Earnings per share available to common stockholders decreased $0.01 as a result of this change.

8. Income Taxes

The effective income tax rate was 38.7% for both the three and six months ended June 30, 2014 and 2013. In determining the provision for income taxes, the Company used an estimated annual effective tax rate, which was based on expected annual income, statutory tax rates, and the Company's best estimate of non-deductible and non-taxable items of income and expense. Income tax expense varies from the amount computed by applying the federal corporate income tax rate of 35.0% to income before income taxes primarily due to state income taxes, net of federal income tax effect, and adjustments for permanent differences.

9. Guarantees

The Company provides a guarantee for a portion of the value of certain independent contractors' ("IC") leased tractors.  The guarantees expire at various dates through 2020.  The potential maximum exposure under these lease guarantees was approximately $13.8 million as of June 30, 2014.  The potential maximum exposure represents the Company’s commitment on remaining lease payments on guaranteed leases as of June 30, 2014.  However, upon an IC default, the Company has the option to purchase the tractor or return the tractor to the leasing company if the residual value is greater than the Company’s guarantee. Alternatively, the Company can contract another IC to assume the lease.  There were no material IC defaults during the three and six months ended June 30, 2014 and 2013. Payments made by the Company under the guarantees were de minimis for the three and six months ended June 30, 2014 and 2013. No liability was recorded as of June 30, 2014 or December 31, 2013.

10. Commitments and Contingencies

In the ordinary course of business, the Company is a defendant in several property and other claims. In the aggregate, the Company does not believe any of these claims will have a material impact on its consolidated financial statements. The Company maintains liability insurance coverage for claims in excess of $500,000 per occurrence and cargo coverage for claims in excess of $100,000 per occurrence. The Company believes it has adequate insurance to cover losses in excess of the deductible amount. As of June 30, 2014 and December 31, 2013, the Company had reserves for estimated uninsured losses of $6.3 million and $5.7 million, respectively.

11. Related Party Transactions

The Company has an advisory agreement with HCI Equity Management L.P. (“HCI”) to pay transaction fees and an annual advisory fee of $0.1 million. A minimal amount of money was paid to HCI for the three and six months ended June 30, 2014. The Company paid an aggregate of $0.1 million to HCI for the advisory fee and travel expenses during the three and six months ended June 30, 2013.

12. Segment Reporting

The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments, which are also the reportable segments: TL, LTL, and TMS.

These reportable segments are strategic business units through which the Company offers different services. The Company evaluates the performance of the segments primarily based on their respective revenues and operating income. Accordingly, interest expense and other non-operating items are not reported in segment results. In addition, the Company has disclosed a corporate segment, which is not an operating segment and includes acquisition transaction expenses, corporate salaries, and share-based compensation expense.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our unaudited condensed consolidated financial statements and the related notes and other financial information included in this Quarterly Report on Form 10-Q. This discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section titled “Risk Factors” included in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2013. This discussion and analysis should also be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” relating to our results for the year ended December 31, 2013, set forth in our Annual Report on Form 10-K for the year ended December 31, 2013.

Overview

We are a leading asset-light transportation and logistics service provider offering a full suite of solutions, including truckload logistics (“TL”), customized and expedited less-than-truckload (“LTL”), transportation management solutions (“TMS”), intermodal solutions (transporting a shipment by more than one mode, primarily via rail and truck), freight consolidation, inventory management, expedited services, international freight forwarding, customs brokerage, and comprehensive global supply chain solutions. We utilize a broad third-party network of transportation providers, comprised of independent contractors (“ICs”) and purchased power providers, to serve a diverse customer base in terms of end market focus and annual freight expenditures. Although we service large national accounts, we primarily focus on small to mid-size shippers, which we believe represent an expansive and underserved market. Our business model is highly scalable and flexible, featuring a variable cost structure that requires minimal investment (as a percentage of revenues) in transportation equipment and facilities, thereby enhancing free cash flow generation and returns on our invested capital and assets.

We have three operating segments:

Truckload Logistics. Within our TL business, we arrange the pickup, delivery, freight consolidation, and inventory management of TL freight through our network of 34 TL service centers, five freight consolidation and inventory management centers, 26 company dispatch offices, and 128 independent brokerage agents located throughout the United States and Canada. We offer temperature-controlled, dry van, intermodal drayage, and flatbed services and specialize in the transport of refrigerated foods, poultry, and beverages. We believe this specialization provides consistent shipping volume year-over-year.

Less-than-Truckload. Our LTL business involves the pickup, consolidation, linehaul, deconsolidation, and delivery of LTL shipments throughout the United States and into Mexico, Puerto Rico, and Canada. With a network of 45 LTL service centers and over 200 third-party delivery agents, we employ a point-to-point LTL model that we believe serves as a competitive advantage over the traditional hub and spoke LTL model in terms of faster transit times, lower incidence of damage, and reduced fuel consumption.

Transportation Management Solutions. Within our TMS business, we offer a “one-stop” domestic and international transportation and logistics solution, including access to the most cost-effective and time-sensitive modes of transportation within our broad network. Specifically, our TMS offering includes pricing, contract management, transportation mode and carrier selection, freight tracking, freight bill payment and audit, cost reporting and analysis, and dispatch. Our customized TMS offering is designed to allow our customers to reduce operating costs, redirect resources to core competencies, improve supply chain efficiency, and enhance customer service. Our TMS segment also includes domestic and international air and ocean transportation services and customs brokerage.

Our success principally depends on our ability to generate revenues through our network of sales personnel and independent brokerage agents and to deliver freight in all modes safely, on time, and cost-effectively through a suite of solutions tailored to the needs of each customer. Customer shipping demand, over-the-road freight tonnage levels, and equipment capacity ultimately drive increases or decreases in our revenues. Our ability to operate profitably and generate cash is also impacted by purchased transportation costs, fuel costs, pricing dynamics, customer mix, and our ability to manage costs effectively. Within our TL business, we typically charge a flat rate negotiated on each load hauled. Within our LTL business, we typically generate revenues by charging our customers a rate based on shipment weight, distance hauled, and commodity type. This amount is typically comprised of a base rate, a fuel surcharge, and any applicable service fees. Within our TMS business, we typically charge a variable rate on each shipment, in addition to transaction or service fees appropriate for the solution we have provided to meet a specific customer’s needs.

We incur costs that are directly related to the transportation of freight, including purchased transportation costs. We also incur indirect costs associated with the transportation of freight that include other operating costs, such as insurance and claims.

13

In addition, we incur personnel–related costs and other operating expenses, collectively discussed herein as other operating expenses, essential to administering our operations. We continually monitor all components of our cost structure and establish annual budgets, which are generally used to benchmark costs incurred on a monthly basis.

Purchased transportation costs within our TL business are typically based on negotiated rates for each load hauled. Purchased transportation costs within our LTL business represent amounts we pay to ICs or purchased power providers and are generally contractually agreed-upon rates. Within our TMS business, purchased transportation costs include payments made to our purchased power providers, which are generally contractually agreed-upon rates. Purchased transportation costs are the largest component of our cost structure. Our purchased transportation costs typically increase or decrease in proportion to revenues.

Our ability to maintain or grow existing tonnage levels is impacted by overall economic conditions, shipping demand, and over-the-road freight capacity in North America, as well as by our ability to compete effectively in terms of pricing, safety, and on-time delivery.

The pricing environment in the transportation industry also impacts our operating performance. Pricing within our TL business generally has fewer influential factors than pricing within our LTL business, but is typically driven by shipment frequency and consistency, length of haul, and customer and geographic mix. Our LTL pricing is typically measured by billed revenue per hundredweight, which is often referred to as “yield.” Our LTL pricing is dictated primarily by factors such as shipment size, shipment frequency and consistency, length of haul, freight density, and customer and geographic mix. Since we offer both LTL and TL shipping as part of our TMS offering, pricing within our TMS segment is impacted by similar factors. The pricing environment for all of our operations generally becomes more competitive during periods of lower industry tonnage levels and increased capacity within the over-the-road freight sector.

The transportation industry is dependent upon the availability of adequate fuel supplies and the price of fuel. Fuel prices have fluctuated dramatically over recent years. Within our TL and TMS businesses, we pass fuel costs through to our customers. As a result, our operating income in these businesses is less impacted by changes in fuel prices. Within our LTL business, our ICs and purchased power providers pass along the cost of diesel fuel to us, and we in turn attempt to pass along some or all of these costs to our customers through fuel surcharge revenue programs. Although revenues from fuel surcharges generally offset increases in fuel costs, other operating costs have been, and may continue to be, impacted by fluctuating fuel prices. The total impact of higher energy prices on other nonfuel-related expenses is difficult to ascertain. We cannot predict future fuel price fluctuations, the impact of higher energy prices on other cost elements, recoverability of higher fuel costs through fuel surcharges, and the effect of fuel surcharges on our overall rate structure or the total price that we will receive from our customers. Depending on the changes in the fuel rates and the impact on costs in other fuel- and energy-related areas, our operating margins could be impacted.

Recent Acquisitions

On February 24, 2014, we acquired all of the outstanding stock of Rich Logistics and Everett Transportation Inc. and certain assets of Keith Everett (collectively, "Rich Logistics") for the purpose of expanding our market presence in the TL segment. Headquartered in Arkansas, Rich Logistics transports product throughout the United States and Mexico utilizing a combination of independent contractors and employee drivers.

On March 14, 2014, we acquired all of the outstanding stock of Unitrans, Inc. ("Unitrans") for the purpose of expanding our market presence in the TMS segment. Headquartered in California, Unitrans is a leading high-quality, non-asset based provider of international logistics solutions. Unitrans offers its customers international ocean and air transportation management, customs house brokerage, and domestic solutions, with a focus on complex cold chain and high value shipments.

On July 18, 2014, we acquired ISI Acquisition Corp. (which wholly owns Integrated Services, Inc. and ISI Logistics Inc.) and ISI Logistics South, Inc. (collectively, "ISI") for the purpose of expanding our presence within the TL segment. Headquartered in Indiana, ISI is a regional logistics provider focused on the warehousing and transportation needs of its customers, primarily in the automotive industry.

Three Months EndedJune 30, 2014 Compared to Three Months EndedJune 30, 2013

Revenues

Consolidated revenues increased by $128.3 million, or 38.6%, to $460.2 million during the second quarter of 2014 from $331.9 million during the second quarter of 2013, the majority of which was attributable to the impact of our 2013 and 2014 acquisitions.

TL revenues increased by $69.6 million, or 43.1%, to $230.8 million during the second quarter of 2014 from $161.2 million during the second quarter of 2013. The acquisitions of Wando Trucking, TA Drayage, G.W. Palmer, YES Trans, and Rich Logistics collectively contributed $48.9 million of the revenue increase. The remaining $20.7 million of the revenue increase was driven by load growth due to the expansion of our IC network, as well as the continued increase in the utilization of our broker agent network.

LTL revenues increased by $3.7 million, or 2.5%, to $150.2 million during the second quarter of 2014 from $146.5 million during the second quarter of 2013. This growth was the result of LTL tonnage growth of 0.4% quarter-over-quarter and a 1.1% increase in shipments quarter-over-quarter. Revenue per hundredweight increased 2.8% quarter-over-quarter. Average length of haul decreased 4.0% quarter-over-quarter as a result of our expanded footprint.

TMS revenues increased by $54.8 million, or 203.4%, to $81.8 million during the second quarter of 2014 from $27.0 million during the second quarter of 2013. This growth was primarily driven by our acquisitions of Adrian Carriers, Marisol, and Unitrans.

Purchased Transportation Costs

Purchased transportation costs increased by $87.4 million, or 38.4%, to $315.3 million during the second quarter of 2014 from $227.9 million during the second quarter of 2013.

TL purchased transportation costs increased by $39.7 million, or 36.4%, to $148.7 million during the second quarter of 2014 from $109.0 million during the second quarter of 2013. This increase was the result of our TL acquisitions of Wando Trucking, TA Drayage, G.W. Palmer, YES Trans, and Rich Logistics, which collectively contributed $24.1 million of the increase, as well as the expansion of our IC network and increased utilization of our broker agent network. TL purchased transportation costs as a percentage of TL revenues decreased to 64.4% during the second quarter of 2014 from 67.6% during the second quarter of 2013, primarily as a result of the 2013 and 2014 acquisitions.

Excluding fuel surcharges, our average linehaul cost per mile increased to $1.28 during the second quarter of 2014 from $1.23 during the second quarter of 2013. Overall, the LTL purchased transportation cost was impacted by a shift in freight mix resulting in an increase in non-metro delivery zones with higher delivery costs and increased purchase power rates.

TMS purchased transportation costs increased by $42.5 million, or 242.7%, to $60.0 million during the second quarter of 2014 from $17.5 million during the second quarter of 2013, primarily due to our acquisitions of Adrian Carriers, Marisol, and Unitrans.

Liquidity and Capital Resources

Our primary sources of cash have been borrowings under our revolving credit facility, cash flows from operations, sales of securities, and equity contributions. Our primary cash needs are and have been to execute our acquisition strategy, fund normal working capital requirements, finance capital expenditures, and repay our indebtedness. As of June 30, 2014, we had $8.3 million in cash and cash equivalents, $39.1 million of availability under our credit facility, and $139.1 million in net working capital. As we continue to execute on our acquisition and growth strategy, additional financing may be necessary within the next 12 months.

19

Although we can provide no assurances, amounts available under our credit facility, net cash provided by operating activities, and available cash and cash equivalents should be adequate to finance working capital and planned capital expenditures for at least the next 12 months. Thereafter, we may find it necessary to obtain additional equity or debt financing as we continue to execute our business strategy.

On July 9, 2014, the Company entered into a fifth amended and restated credit agreement with U.S. Bank and other lenders. Our credit facility consists of a $200.0 million term loan and a revolving credit facility up to a maximum aggregate amount of $350.0 million, of which up to $10.0 million may be used for Swing Line Loans (as defined in the credit agreement) and up to $30.0 million may be used for letters of credit. The credit facility matures on July 9, 2019.

Advances under our credit facility bear interest at either (a) the Eurocurrency Rate (as defined in the credit agreement), plus an applicable margin in the range of 2.0% to 3.0%, or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.0%.

Our credit agreement contains certain financial covenants, including a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. In addition, our credit agreement contains negative covenants limiting, among other things, additional indebtedness, capital expenditures, transactions with affiliates, additional liens, sales of assets, dividends, investments, advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. As of and during the three and six months ended June 30, 2014, we were in compliance with all covenants contained in the fourth amended and restated credit agreement. Our credit agreement also contains customary events of default, including payment defaults, breaches of representations and warranties, covenant defaults, events of bankruptcy and insolvency, failure of any guaranty or security document supporting the credit agreement to be in full force and effect, and a change of control of our business.

Cash Flows

A summary of operating, investing, and financing activities are shown in the following table (in thousands):

	Six Months Ended June 30,
	2014			2013
Net cash provided by (used in):
Operating activities	$	3,504		$	17,600
Investing activities	(118,430		)	(47,181		)
Financing activities	117,829			23,096
Net change in cash and cash equivalents	$	2,903		$	(6,485	)

Cash Flows from Operating Activities

Cash provided by operating activities primarily consists of net income adjusted for certain non-cash items, including depreciation and amortization, share-based compensation, provision for bad debts, deferred taxes, and the effect of changes in working capital and other activities.

The difference between our $25.2 million net income and the $3.5 million cash provided by operating activities during the six months ended June 30, 2014 was primarily attributable to a $36.8 million increase in our accounts receivable, a $1.5 million decrease in accrued expenses, and excess tax benefit on share-based compensation of $1.4 million, which was primarily offset by $11.3 million of depreciation and amortization, deferred tax provision of $3.2 million, $1.1 million of share-based compensation, a $0.9 million increase in accounts payable, $0.9 million of provision for bad debt, and a $0.6 million decrease in prepaid expenses and other assets. The overall changes in cash flow from operating activities were impacted by the acquisition growth during the second quarter of 2014.

Cash Flows from Investing Activities

Cash used in investing activities was $118.4 million during the six months ended June 30, 2014, which primarily reflects $100.8 million used for our acquisitions of Rich Logistics and Unitrans, and $20.5 million of capital expenditures used to support our operations. These payments were offset by the proceeds from the sale of buildings and equipment of $2.8 million.

Cash Flows from Financing Activities

Cash provided by financing activities was $117.8 million during the six months ended June 30, 2014, which primarily reflects net borrowings of $118.5 million under our credit facility, payment of contingent earnouts of $4.8 million, proceeds from the issuance of common stock upon the exercise of stock options of $2.7 million, and excess tax benefits on share-based compensation of $1.4 million.

Critical Accounting Policies and Estimates

In preparing our condensed consolidated financial statements, we applied the same critical accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2013 that affect judgments and estimates of amounts recorded for certain assets, liabilities, revenues, and expenses.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Commodity Risk

In our TL, LTL, and TMS businesses, our primary market risk centers on fluctuations in fuel prices, which can affect our profitability. Diesel fuel prices fluctuate significantly due to economic, political, and other factors beyond our control. Our ICs and purchased power providers pass along the cost of diesel fuel to us, and we in turn attempt to pass along some or all of these costs to our customers through fuel surcharge revenue programs. There can be no assurance that our fuel surcharge revenue programs will be effective in the future. Market pressures may limit our ability to pass along our fuel surcharges.

Interest Rate Risk

We have exposure to changes in interest rates on our revolving credit facility and term loan. The interest rate on our revolving credit facility and term loan fluctuate based on the prime rate or LIBOR plus an applicable margin. Assuming our $350.0 million revolving credit facility was fully drawn and taking into consideration the outstanding term loan of $166.3 million as of June 30, 2014, a 1.0% increase in the borrowing rate would increase our annual interest expense by $5.2 million. We do not use derivative financial instruments for speculative trading purposes and are not engaged in any interest rate swap agreements.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended ("Exchange Act")). Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2014, our disclosure controls and procedures were effective, with reasonable assurance, to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, misstatements, errors, and instances of fraud, if any, within our company have been or will be prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls also can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, internal controls may become inadequate as a result of changes in conditions, or through the deterioration of the degree of compliance with policies or procedures.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

From time to time, we are involved in litigation and proceedings in the ordinary course of our business. We are not currently involved in any legal proceeding that we believe would have a material effect on our business or financial condition.

ITEM 1A. RISK FACTORS.

An investment in our common stock involves a high degree of risk. You should carefully consider the factors described in our Annual Report form 10-K for the year ended December 31, 2013 in analyzing an investment in our common stock. If any suck risks occur, our business, financial condition, and results of operations would likely suffer, the trading price of our common stock would decline, and you could lose all or part of the money you paid for our common stock. In addition, the risk factors and uncertainties could cause our actual results to differ materially from those projected in our forward-looking statements, whether made in this report or other documents we file with the SEC, or our annual or quarterly reports to stockholders, future press releases, or orally, whether in presentations, responses to questions, or otherwise.

There have been no material changes to the Risk Factors described under “Part I - Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair value measurement

4. Fair Value Measurement

Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1 — Quoted market prices in active markets for identical assets or liabilities.

Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3 — Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.

A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

The following table presents information, as of June 30, 2014 and December 31, 2013, about the Company’s financial liabilities. Contingent purchase price related to acquisitions is measured at fair value on a recurring basis, according to the valuation techniques the Company used to determine fair value (in thousands):

	June 30, 2014
	Level 1		Level 2		Level 3		Fair Value
Contingent purchase price related to acquisitions	$	—	$	—	$	11,726	$	11,726
Total liabilities at fair value	$	—	$	—	$	11,726	$	11,726

	December 31, 2013
	Level 1		Level 2		Level 3		Fair Value
Contingent purchase price related to acquisitions	$	—	$	—	$	17,054	$	17,054
Total liabilities at fair value	$	—	$	—	$	17,054	$	17,054

In measuring the fair value of the contingent purchase price liability, the Company used an income approach that considers the expected future earnings of the acquired businesses and the resulting contingent payments, discounted at a risk-adjusted rate.

The table below sets forth a reconciliation of the Company’s beginning and ending Level 3 financial liability balance for the three and six months ended June 30, 2014 and 2013 and the year ended December 31, 2013 (in thousands):

Goodwill and Intangible Assets

3. Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price of all acquisitions over the estimated fair value of the net assets acquired. The Company performs an impairment test of goodwill annually as of July 1. The 2013 impairment test did not result in any impairment losses. There is no goodwill impairment for any of the periods presented in the Company's condensed consolidated financial statements.

The following is a rollforward of goodwill from December 31, 2013 to June 30, 2014 by reportable segment (in thousands):

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization, Nature of Business and Significant Accounting Policies

1. Organization, Nature of Business and Significant Accounting Policies

Nature of Business

Roadrunner Transportation Systems, Inc. (the “Company”) is headquartered in Cudahy, Wisconsin and has the following three operating segments: truckload logistics (“TL”), less-than-truckload (“LTL”), and transportation management solutions (“TMS”). Within its TL business, the Company operates a network of 34 TL service centers, five freight consolidation and inventory management centers, and 26 company dispatch offices and is augmented by 128 independent brokerage agents. Within its LTL business, the Company operates 45 LTL service centers throughout the United States, complemented by relationships with over 200 delivery agents. Within its TMS business, the Company operates from ten service centers and nine dispatch offices throughout the United States. From pickup to delivery, the Company leverages relationships with a diverse group of third-party carriers to provide scalable capacity and reliable, customized service, including domestic and international air and ocean transportation services, to its customers. The Company operates primarily in the United States.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Segment Reporting

The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments, which are also its reportable segments: TL, LTL, and TMS.

The acquisitions of Rich Logistics and Unitrans (collectively, "2014 acquisitions") are considered individually immaterial, but material in the aggregate. The following table summarizes, in the aggregate, the allocation of the purchase price paid to the fair value of the net assets for the 2013 and 2014 acquisitions (in thousands):

	2014 Acquisitions			2013 Acquisitions
Accounts receivable	$	26,107		$	22,666
Other current assets	2,264			922
Property and equipment	17,217			14,392
Goodwill	53,812			78,646
Customer relationship intangible assets	20,894			19,727
Other noncurrent assets	242			12
Accounts payable and other liabilities	(19,726		)	(35,717		)
Total	$	100,810		$	100,648

The goodwill for the acquisitions, in the aggregate, is a result of acquiring and retaining the existing workforces and expected synergies from integrating the operations into the Company. Goodwill of $2.0 million associated with the asset purchases will be deductible for tax purposes while the remaining goodwill will not be deductible for tax purposes. Purchase accounting is considered final for 2013 acquisitions of Wando and Adrian. Purchase accounting is considered preliminary for the 2013 acquisitions of Marisol, TA Drayage, G.W. Palmer, and YES Trans with respect to deferred taxes and revenue recognition. Purchase accounting is considered preliminary for the 2014 acquisitions as final information was not available as of June 30, 2014.

From the dates of acquisition through June 30, 2013, the 2013 acquisitions contributed revenues of $7.7 million and net income of $0.8 million for the three and six months ended June 30, 2013. The following supplemental unaudited pro forma financial information of the Company for the three and six months ended June 30, 2013 includes the results of operations for the 2013 acquisitions, in the aggregate, as if the acquisitions had been completed on January 1, 2012 (in thousands):

	2013		2013
Revenues	$	375,038	$	722,111
Net income	$	13,885	$	24,724

The following supplemental unaudited pro forma financial information of the Company for the three and six months ended June 30, 2013 and the six months ended June 30, 2014 includes the results of operations for the 2014 acquisitions, in the aggregate, as if the acquisitions had been completed on January 1, 2013 (in thousands). The 2014 acquisitions were completed in the first quarter of 2014; accordingly, the actual and pro forma results for the three months ended June 30, 2014 are the same.

			Six Months Ended June 30,
	2013		2014		2013
Revenues	$	384,602	$	876,292	$	729,239

12. Segment Reporting

The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments, which are also the reportable segments: TL, LTL, and TMS.

These reportable segments are strategic business units through which the Company offers different services. The Company evaluates the performance of the segments primarily based on their respective revenues and operating income. Accordingly, interest expense and other non-operating items are not reported in segment results. In addition, the Company has disclosed a corporate segment, which is not an operating segment and includes acquisition transaction expenses, corporate salaries, and share-based compensation expense.

The following table reflects certain financial data of the Company’s reportable segments for the three and six months ended June 30, 2014 and 2013 and as of June 30, 2014 and December 31, 2013 (in thousands):

Earnings Per Share [Abstract]

Earnings Per Share

7. Earnings Per Share

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of common stock outstanding during the period. For the three and six months ended June 30, 2014 and 2013, diluted earnings per share was calculated by dividing net income available to common stockholders by the weighted average common stock outstanding plus stock equivalents that would arise from the assumed exercise of stock options, the conversion of warrants, and the delivery of stock underlying restricted stock units using the treasury stock method. There is no difference, for any of the periods presented, in the amount of net income available to common stockholders used in the computation of basic and diluted earnings per share.

As of June 30, 2014, all stock options, warrants, and restricted stock units were included in the computation of diluted earnings per share. The following table reconciles basic weighted average stock outstanding to diluted weighted average stock outstanding for the three and six months ended June 30, 2014 and 2013 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,

Diluted weighted average stock outstanding	39,330	37,307	39,254	37,051

(1) For the six months ended June 30, 2013, the warrants increased by 609 from the amount previously reported to correct an error. Earnings per share available to common stockholders decreased $0.01 as a result of this change.

The Company operates primarily in the United States.

Principles of Consolidation

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Segment Reporting

Segment Reporting

Income Taxes

8. Income Taxes

The effective income tax rate was 38.7% for both the three and six months ended June 30, 2014 and 2013. In determining the provision for income taxes, the Company used an estimated annual effective tax rate, which was based on expected annual income, statutory tax rates, and the Company's best estimate of non-deductible and non-taxable items of income and expense. Income tax expense varies from the amount computed by applying the federal corporate income tax rate of 35.0% to income before income taxes primarily due to state income taxes, net of federal income tax effect, and adjustments for permanent differences.

Guarantees

9. Guarantees

The Company provides a guarantee for a portion of the value of certain independent contractors' ("IC") leased tractors.  The guarantees expire at various dates through 2020.  The potential maximum exposure under these lease guarantees was approximately $13.8 million as of June 30, 2014.  The potential maximum exposure represents the Company’s commitment on remaining lease payments on guaranteed leases as of June 30, 2014.  However, upon an IC default, the Company has the option to purchase the tractor or return the tractor to the leasing company if the residual value is greater than the Company’s guarantee. Alternatively, the Company can contract another IC to assume the lease.  There were no material IC defaults during the three and six months ended June 30, 2014 and 2013. Payments made by the Company under the guarantees were de minimis for the three and six months ended June 30, 2014 and 2013. No liability was recorded as of June 30, 2014 or December 31, 2013.

The credit agreement is collateralized by all assets of the Company and contains certain financial covenants, including a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. Additionally, the credit agreement contains negative covenants limiting, among other things, additional indebtedness, capital expenditures, transactions with affiliates, additional liens, sales of assets, dividends, investments, advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. As of and during the three and six months ended June 30, 2014, the Company was in compliance with all covenants contained in the credit agreement. Borrowings under the credit agreement bear interest at either (a) the Eurocurrency Rate (as defined in the credit agreement), plus an applicable margin in the range of 2.0% to 3.3%, or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.3%. The revolving credit facility also provides for the issuance of up to $30.0 million in letters of credit. As of June 30, 2014, the Company had outstanding letters of credit totaling $16.0 million. As of June 30, 2014, total availability under the revolving credit facility was $39.1 million and the average interest rate on the credit agreement was 3.4%.
