TAMPA, FL – August 6, 2012 – Quality Distribution, Inc. (NASDAQ: QLTY) (“Quality” or the “Company”), which operates within North America the largest chemical bulk logistics network, a growing unconventional oil and gas frac shale energy logistics business, and the largest provider of intermodal tank container and depot services, today reported net income of $28.8 million, or $1.04 per diluted share, for the second quarter ended June 30, 2012, compared to net income of $9.0 million, or $0.37 per diluted share, in the second quarter ended June 30, 2011.

Net income for the second quarter of 2012 included a $22.8 million non-cash benefit resulting from releasing a substantial portion of the Company’s deferred tax valuation allowance. This release was due to the Company’s improved operating results and the determination that it is more likely than not that expected future taxable income will be sufficient to utilize most of the Company’s deferred tax assets.

After applying a normalized tax rate of 39%, excluding the release of the deferred tax valuation allowance and excluding other items the Company does not consider to be part of regular operating activities, adjusted net income for the second quarter of 2012 was $6.5 million, or $0.24 per diluted share, compared to adjusted net income of $5.6 million, or $0.23 per diluted share, for the same quarter in 2011. Pre-tax items identified to arrive at adjusted net income totaled $4.3 million in the second quarter of 2012, including $2.6 million of costs related to acquisitions, $0.9 million of lease termination and severance charges, and $0.8 million of unusual legal and claims settlement expenses. Adjusted net income for the second quarter of 2011 was derived by excluding a restructuring credit of $0.5 million, and then applying a normalized tax rate of 39%. A reconciliation of net income to adjusted net income is included in the attached financial exhibits.

“Second quarter earnings and year-to-date performance improved from last year, and we anticipate improvement in the second half of the year as we realize further benefits from our recent acquisitions, improve utilization of start-up energy assets, and stabilize our chemical segment volumes via driver additions,” said Gary Enzor, Chief Executive Officer.

Mr. Enzor continued, “The quarter was highlighted by several strategic acquisitions within our energy logistics business. The previously announced acquisitions of Trojan Vacuum, Wylie Bice and RM Resources, coupled with today’s announcement of the Dunn’s and Nassau transactions, have expanded the geographic reach of our energy logistics business considerably. We are now operating in five separate shale regions within the U.S., providing us with regional diversity, expanded customer relationships and increased flexibility towards maximizing our productivity.”

Total revenue for the second quarter of 2012 was $212.7 million, an increase of 12.0% versus the same quarter last year. Excluding fuel surcharges, revenue for the second quarter of 2012 increased 15.0% compared to the prior-year period. This quarter-over-quarter increase in revenue of $23.5 million (excluding fuel surcharges) was driven primarily by $24.1 million of higher revenues from the Company’s energy logistics business, with approximately 54% of the increase resulting from the Bice and Trojan acquisitions described below. Higher demand and pricing led to a $3.9 million increase in intermodal revenues, which was offset by $4.5 million of lower revenues in the chemical logistics business. Lower chemical revenues were primarily driven by reduced volumes, partially offset by higher pricing.

Operating income for the second quarter of 2012 was $13.4 million, a decrease of 20.6% versus the second quarter of 2011. The decline was primarily due to approximately $4.3 million of costs not considered to be from normal operating activities referenced above. Excluding these items, operating income would have been $17.7 million, up 7.9% from the comparable prior year period (excluding a $0.5 million restructuring credit in that period). This improvement was largely due to higher profitability from the energy logistics and intermodal businesses, partially offset by lower chemical profitability. Chemical logistics segment margins in the second quarter (after adjusting for the items mentioned above) fell approximately 60 basis points, driven primarily by a 3.5% decline in revenue excluding fuel surcharges.

Adjusted EBITDA for the second quarter of 2012 was $23.0 million, up 12.4% versus the comparable prior-year period, driven primarily from the energy logistics business profitability and acquisitions. A reconciliation of net income to adjusted EBITDA is included in the attached financial exhibits.

Significant Recent Transactions

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 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. The transactions are expected to be accretive to earnings in 2012. Please see the press release issued today for additional information on these transactions.

As previously announced, on June 1, and June 11, 2012, the Company acquired the operating assets of Wylie Bice Trucking, LLC and the operating assets and rights of RM Resources, LLC, respectively, (collectively “Bice”) for aggregate consideration of $81.4 million, plus potential additional consideration of $19.0 million to be paid in cash, subject to Bice achieving future operating and financial performance criteria.

Also, as previously announced, on April 1, 2012, the Company acquired the operating assets of Trojan Vacuum Services (“Trojan”) for cash consideration of $8.7 million, plus potential additional consideration of $1.0 million to be paid in cash, subject to Trojan achieving future operating and financial performance criteria.

In conjunction with the recent transactions, the Company incurred acquisition-related costs of approximately $2.6 million during the second quarter of 2012, which are included within selling and administrative expenses. The second quarter of 2012 includes three months of operating results from the Trojan business and one month of operating results from the Bice business.

Balance Sheet and Cash Flow

Availability under the Company’s ABL Facility was $86.1 million at June 30, 2012, an increase of $3.8 million versus December 31, 2011 availability. 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 quarter of 2012, borrowings were utilized primarily to fund the Bice and Trojan acquisitions. The Company expects to have sufficient availability under its ABL Facility to support its on-going operations following the Trojan, Bice and Dunn’s acquisitions.

Operating cash flows for the quarter ended June 30, 2012 were $1.7 million, compared with $6.7 million in the same period last year. The decline was primarily due to the expected increase in working capital requirements from our energy logistics business. Operating cash flows are typically lower in the first half of the year and higher in the second half of the year. Net capital expenditures for the quarter ended June 30, 2012 were $0.1 million. The Company purchased $1.9 million of growth-related energy logistics equipment during the quarter, almost fully offset by $1.8 million of sales of chemical logistics equipment.

“We continue to generate strong free cash flow from each of our business segments, and remain focused on asset rationalization and deploying our capital in a disciplined way to ensure we add value for our shareholders,” said Joe Troy, Chief Financial Officer. “We are confident that our recent acquisitions in the unconventional oil and gas frac shale industry will meet our earnings and cash flow expectations, and we will look to drive efficiencies across our growing operations.”

Other

As a result of the release of the deferred tax valuation allowance discussed earlier, the Company estimates that its 2012 effective tax rate, excluding the effect of the release of the Company’s deferred tax valuation allowance, for GAAP purposes will approximate statutory rates. It is important to note that while the Company’s future effective tax rate for GAAP purposes will increase, the change will not adversely impact the usage of the Company’s $77.0 million of Net Operating Losses (“NOLs”) (as of December 31, 2011) and will have no immediate effect on the Company’s cash expenditures for taxes. The Company continues to expect to pay only minimal cash for income taxes until the total amount of the NOLs are fully utilized.

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 Six, Months Ended June 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, 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, 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 significant items that are not part of regular operating activities, including acquisition costs, severance and lease termination costs, unusual legal and claims settlements, 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.
