TAMPA, FL – November 6, 2012 – Quality Distribution, Inc. (NASDAQ: QLTY) (“Quality” or the “Company”), a North American logistics and transportation provider with market leading businesses, today reported net income of $8.9 million, or $0.32 per diluted share, for the third quarter ended September 30, 2012, compared to net income of $6.2 million, or $0.25 per diluted share, in the third quarter ended September 30, 2011. Net income for the third quarter of 2012 included a $4.9 million non-cash benefit from releasing a portion of the Company’s deferred tax valuation allowance.

Adjusted net income for the third quarter of 2012 was $4.8 million, or $0.17 per diluted share, compared to adjusted net income of $4.9 million, or $0.20 per diluted share, for the same quarter in 2011. Both periods are calculated by applying a normalized tax rate of 39% and excluding other items not considered part of regular operating activities.

Adjusted pre-tax income for the third quarter of 2012 included $3.5 million of costs related to the following: the previously disclosed termination of an independent affiliate relationship ($3.0 million), recent acquisition activity ($0.4 million), and severance charges ($0.1 million). Adjusted net income for the same period last year was derived by excluding debt issuance write-off costs of $1.4 million. A reconciliation of net income to adjusted net income is included in the attached financial exhibits.

“Our third quarter proved to be a real challenge, with the highly unusual circumstance whereby all three of our segments reported lower than expected results. Based on what we see today, especially with the impact of Hurricane Sandy in the Northeast, our fourth quarter will be equally challenging,” said Gary Enzor, Chief Executive Officer. “Despite these issues, we anticipate improved year-over-year performance in all of our segments in 2013. Given that we now have an excellent footprint in the energy space, our plans over the near-term are to optimize our existing and recently acquired operations, as well as generate free cash flow to reduce debt.”

Third Quarter Consolidated Results

Total revenue for the third quarter of 2012 was $222.1 million, an increase of 11.4% versus the same quarter last year. Excluding fuel surcharges, revenue for the third quarter of 2012 increased 13.3% compared to the prior-year period. This revenue improvement was driven primarily by a $19.5 million increase from the Energy Logistics business, $2.5 million of growth from Intermodal, and a $0.5 million increase from the Chemical Logistics business.

Operating income for the third quarter of 2012 was $11.6 million, a decrease of $3.7 million versus the prior-year period, driven primarily by the aforementioned independent affiliate conversion. Adjusting for this conversion, and the acquisition and severance costs mentioned above, third quarter 2012

operating income would have been approximately $15.2 million, or flat versus the prior-year third quarter. Operating margin declined primarily as a result of higher equipment lease expense and lower asset utilization within the Chemical and Energy segments, as well as higher depreciation and amortization expenses from the Company’s recent asset acquisitions.

Adjusted EBITDA for the third quarter of 2012 was $22.2 million, up 14.5% compared to the third quarter of 2011, driven primarily by income from Energy Logistics acquisitions consummated in 2012. A reconciliation of net income to adjusted EBITDA is included in the attached financial exhibits.

Third Quarter Segment Results

Chemical Logistics

Revenues in the Chemical Logistics segment were $151.4 million in the third quarter of 2012, which was up slightly versus the third quarter of 2011. Excluding fuel surcharges, revenues increased $0.5 million. The Company believes that the leadership team within this segment was successful in protecting most of the revenue related to the affiliate conversion, and expects to gain revenue following the transition in the coming quarters.

Operating income in the Chemical Logistics segment was $6.9 million, which was down $2.9 million versus the comparable prior-year period, primarily due to approximately $1.7 million of affiliate conversion, acquisition and severance charges. After adjusting for these charges, operating income was down $1.2 million, primarily related to higher equipment lease expense and lower asset utilization primarily in the Northeast region of the U.S.

Intermodal

Revenues in the Intermodal segment were $32.2 million, up $2.6 million or 8.8% versus the prior-year period. Excluding fuel surcharges, revenues increased 9.6% primarily due to continued higher demand for ISO container shipments, as well as the positive effects of the Greensville acquisition.

Operating income in the Intermodal segment was $3.4 million, down $1.3 million versus the prior-period. This quarter-over-quarter decline was primarily due to higher than expected equipment repair costs, increased overtime charges, and medical benefit expenses. These third quarter impacts represent temporary items that are expected to improve going forward.

Energy Logistics

Revenues in the Energy Logistics segment were $38.5 million, up $19.8 million versus the prior year period. Revenue increases from the recent acquisitions of Bice, Trojan and Dunn’s were partially offset by a steep decline in drilling activity from the Marcellus shale region. The decline in Marcellus revenue was driven primarily by lower natural gas prices, and partly by the independent affiliate conversion.

Operating income in the Energy Logistics segment was $1.4 million, an increase of $0.4 million versus the prior year period as significant affiliate conversion costs nearly offset higher income from acquisitions. Excluding $1.8 million of affiliate conversion costs, operating income increased $2.3 million, driven by higher margins from the acquisitions. Operating margins were also adversely impacted by $2.1 million of increased depreciation and amortization expenses resulting from asset purchase accounting allocations and lower utilization. Excluding the previously mentioned affiliate conversion costs, EBITDA from the Energy Logistics segment for the third quarter was $5.6 million, up $4.4 million versus the prior-year period.

Summary

“This quarter was well below expectations as we encountered headwinds that adversely impacted the performance within each of our business segments,” said Gary Enzor, Chief Executive Officer. “However, we did achieve positive year-over-year revenue in our Chemical Logistics business, representing a significant improvement versus our last several quarters. We also recently finalized the affiliate transition that caused a strain on resources and profitability during the last several months.”

Significant Recent Transactions

Due to financial and operational difficulties encountered by one of our larger independent affiliates, the Company terminated its business relationship with this independent affiliate during the third quarter of 2012. This independent affiliate operated eight terminals within the Chemical Logistics segment and one terminal within the Energy Logistics segment. Four Chemical Logistics terminals were transitioned to other independent affiliates, with the remaining terminals transitioned to company operations. During this transition, operating results for the third quarter of 2012 were adversely impacted by $3.0 million of greater than expected operating costs and reduced profitability.

Despite costs associated with the independent affiliate transition, Quality and certain other independent affiliates provided a smooth conversion of the business and retained the majority of the revenue. In connection with the business transition, on October 17, 2012 Quality acquired certain operating assets from this independent affiliate for approximately $17.1 million in cash. The Company expects to incur a moderate amount of additional expense in the fourth quarter related to the independent affiliate transition.

On August 1, 2012, the Company completed the acquisition of the operating assets of Dunn’s Tank Services, Inc., and the operating assets and rights of Nassau Disposal, Inc. (collectively “Dunn’s”), for aggregate cash consideration of $34.3 million. Potential additional consideration of $3.6 million may be paid in cash, subject to Dunn’s achieving certain future operating and financial performance criteria. Dunn’s has trucking operations in both the Woodford and Utica shale, including two operating salt-water disposal wells in Oklahoma.

In June 2012, the Company acquired the operating assets of Wylie Bice Trucking, LLC and the operating assets and rights of RM Resources, LLC, (collectively “Bice”) for aggregate consideration of $81.4 million, plus additional contingent consideration of $19.0 million, subject to Bice achieving certain future operating and financial performance criteria. In April 2012, the Company acquired the operating assets of Trojan Vacuum Services (“Trojan”) for cash consideration of $8.7 million, plus additional contingent consideration of $1.0 million, subject to Trojan achieving certain future operating and financial performance criteria.

In conjunction with these various transactions, the Company incurred acquisition-related costs of approximately $3.0 million during the first half of 2012 and $0.4 million during the third quarter of 2012, which are included within selling and administrative expenses. The Company’s results for the third quarter of 2012 include three months of operating results from Bice and Trojan and two months of operating results from Dunn’s. Results for the third quarter of 2011 do not include any of these operating results.

Balance Sheet and Cash Flow

On September 27, 2012, the Company increased the maximum borrowing capacity of its ABL Facility from $250 million to $350 million, utilizing the facility’s accordion feature. Substantially all other terms remain unchanged, and the Company’s immediate borrowing availability did not change as a result of the increase in capacity. Borrowing availability under the Company’s ABL Facility was $68.4 million at September 30, 2012, a decrease of $13.9 million versus December 31, 2011 availability of $82.3 million. During the first quarter of 2012, net proceeds from the Company’s sale of common stock were used to repay outstanding borrowings on the ABL Facility, and during the second and third quarters of 2012, borrowings were utilized primarily to fund the Trojan, Bice, and Dunn’s acquisitions. The Company expects to have sufficient borrowing availability under its ABL Facility to support its on-going operations following the previously mentioned acquisitions.

Operating cash flows for the quarter ended September 30, 2012 were $5.2 million, compared with $12.8 million in the quarter ended September 30, 2011. The decline was primarily due to the expected increase in working capital requirements from the growing Energy Logistics business. Net capital expenditures for the quarter ended September 30, 2012 were $9.0 million, most of which were targeted to growth opportunities.

“Our Bice and Dunn’s acquisitions have gotten off to a slower start than we had originally expected, as lower commodity pricing for natural gas and oil reduced drilling activity, thereby negatively impacting demand for transportation services primarily in the Bakken and Woodford shale regions. We also made significant capital investments and lease commitments for tractor and trailer assets in anticipation of higher levels of demand, which have not yet materialized and in turn hurt near-term productivity and profitability,” said Joe Troy, Chief Financial Officer.

Mr. Troy continued, “During the remainder of this year and into 2013, we will focus our efforts on asset utilization across each business unit, reposition assets into areas with the greatest growth potential and rationalize our fleet where warranted. We feel confident that each of our business units is taking the necessary actions to improve profitability, and the Company is well positioned to reduce leverage and generate improved earnings and free cash flow in 2013.”

The Company has three reportable business segments for financial reporting purposes that are distinguished primarily on the basis of services offered:

RECONCILIATION OF NET INCOME TO ADJUSTED NET INCOME, EBITDA AND ADJUSTED EBITDA AND RECONCILIATION OF NET INCOME PER SHARE TO ADJUSTED NET INCOME PER SHARE

For the Three Months and Nine Months Ended September 30, 2012 and 2011

(In 000’s)

Unaudited

Adjusted Net Income and Adjusted Net Income per Share, EBITDA and Adjusted EBITDA are not measures of financial performance or liquidity under United States Generally Accepted Accounting Principles (“GAAP”). Adjusted Net Income and Adjusted Net Income per Share, EBITDA and Adjusted EBITDA are presented herein because they are important metrics used by management to evaluate and understand the performance of the ongoing operations of Quality’s business. For Adjusted Net Income, management uses a 39% tax rate for calculating the provision for income taxes to normalize Quality’s tax rate to that of competitors, and to compare Quality’s reporting periods with different effective tax rates. In addition, in arriving at Adjusted Net Income and Adjusted Net Income per Share, the Company adjusts for significant items that are not part of regular operating activities. These adjustments include acquisition costs, severance and lease termination costs, unusual legal and claims settlements, independent affiliate conversion costs, restructuring credits and the write-off of debt issuance costs.

EBITDA is a component of the measure used by Quality’s management to facilitate internal comparisons to competitors’ results and the bulk transportation, chemical and energy logistics and intermodal industries in general. We believe that financial information based on GAAP for businesses, such as Quality’s, should be supplemented by EBITDA so investors better understand the financial information in connection with their evaluation of the Company’s business. This measure addresses variations among companies with respect to capital structures and cost of capital (which affect interest expense) and differences in taxation and book depreciation of facilities and equipment (which affect relative depreciation expense), including significant differences in the depreciable lives of similar assets among various companies. Accordingly, EBITDA allows analysts, investors and other interested parties in the bulk transportation, logistics and intermodal industries to facilitate company-to-company comparisons by eliminating some of the foregoing variations. EBITDA as used herein may not, however, be directly comparable to similarly titled measures reported by other companies due to differences in accounting policies and items excluded or included in the adjustments, which limits its usefulness as a comparative measure. To calculate EBITDA, Net Income is adjusted for provision for (benefit from) income tax, depreciation and amortization and net interest expense. To calculate Adjusted EBITDA, we calculate EBITDA from Net Income, which is then further adjusted for items that are not part of regular operating activities, including acquisition costs, severance and lease termination costs, unusual legal and claims settlements, independent affiliate conversion costs, restructuring credits and the write-off of debt issuance costs, and other non-cash items such as non-cash stock-based compensation. Adjusted Net Income and Adjusted Net Income per Share, EBITDA and Adjusted EBITDA should not be considered in isolation or as a substitute for the consolidated statements of operations prepared in accordance with GAAP, or as an indication of Quality’s operating performance or liquidity.
