TAMPA, FL – May 4, 2011 – Quality Distribution, Inc. (NASDAQ: QLTY) (“Quality” or the “Company”), which operates the largest chemical bulk tank truck network and is the largest provider of intermodal tank container and depot services in North America, today reported net income of $2.7 million, or $0.12 per diluted share, for the first quarter ended March 31, 2011, compared to net income of $0.8 million, or $0.04 per diluted share, in the first quarter ended March 31, 2010.

Adjusted net income for the first quarter of 2011 was $2.8 million, or $0.12 per diluted share, compared to adjusted net income of $0.8 million, or $0.04 per diluted share, for the same quarter in 2010. Adjusted net income for the first quarter of 2011 was derived by excluding a pre-tax, non-cash charge of approximately $1.8 million for the write-off of debt issuance costs associated with the prepayment of approximately $27.5 million of the Company’s 11.75% PIK Notes during the first quarter of 2011; a normalized tax rate of 39% was then applied to arrive at the adjusted net income. Adjusted net income for the first quarter of 2010 was derived by excluding a restructuring charge of approximately $1.1 million, and then applying a normalized tax rate of 39%. These adjustment items are excluded as the Company does not consider the costs to be part of regular operating activities. A reconciliation of net income to adjusted net income is included in the attached financial exhibits.

The significant improvement in earnings for the first quarter ended March 31, 2011 was driven by a 24.0% increase in quarter-over-quarter operating income (after adjusting for the restructuring charge in last year’s first quarter) resulting from solid revenue growth as well as cost containment initiatives. On the same comparative basis, first quarter 2011 operating margins improved approximately 80 basis points versus the prior year period, primarily due to lower maintenance and depreciation expenses resulting from our fleet rationalization program in 2010. These expense improvements were only partially offset by higher insurance costs, $0.3 million of severance charges related to headcount reductions and higher administrative costs primarily due to a $0.5 million non-cash charge against a note receivable from an independent affiliate.

“I am very pleased with our first quarter earnings per share in what has traditionally been our seasonally slowest period,” said Gary Enzor, Chief Executive Officer. “Both our core logistics and Boasso’s intermodal business units delivered stronger year over year performance, despite difficult weather conditions in our Northeast and Midwest regions. Our core bulk chemical transportation market continues to be capacity constrained, which bodes well for ongoing improvements in our asset utilization.”

Total revenue for the first quarter ended March 31, 2011 was $177.9 million, an increase of 10.3% versus the same quarter last year. Excluding fuel surcharges, revenue for the first quarter of 2011 increased 5.3% compared to the prior-year quarter. This increase was driven primarily by higher pricing within our logistics operations and the addition of a new independent affiliate in 2010, as well as a 13.8% increase in revenues (excluding fuel surcharges), from our intermodal business on strong international shipment volumes and higher depot revenue.

Adjusted EBITDA for the first quarter of 2011 was $16.4 million, up 13.0% versus the comparable prior-year period, driven primarily from higher pricing and an increase in Boasso’s intermodal operating results. A reconciliation of net income to adjusted EBITDA is included in the attached financial exhibits.

Gary Enzor commented further, “We are off to a great start in 2011 and remain excited about our various opportunities for growth this year as we intend to leverage our asset-light business model and improved balance sheet to bring this growth to fruition. We remain optimistic about the remainder of the year as we head into our seasonally strong quarters, and look forward to pursuing our multifaceted growth strategy and delivering enhanced value to our shareholders.”

Significant Transaction and Other

On February 9, 2011, Quality sold 2.0 million shares of its common stock in a public offering at a gross price of $9.50 per share and received net proceeds, after fees and expenses, of approximately $17.5 million. Quality utilized the net proceeds from the common stock offering to redeem at par, plus accrued and unpaid interest, $17.5 million of its 11.75% PIK Notes. In conjunction with Quality’s public sale of common stock, certain affiliates of Apollo Management, L.P. ("Apollo") sold 2.6 million of its shares, reducing Apollo’s ownership from 48.9% prior to the offering to approximately 33.4%.

Capital expenditures for the first quarter of 2011 were $3.2 million and proceeds from sales of equipment were $2.9 million. Availability under the Company’s asset-based revolving credit facility (“ABL Facility”) at March 31, 2011 was $77.1 million, an increase of $23.0 million, or 42.5%, from availability under the ABL Facility at March 31, 2010. Sequentially from December 31, 2010, availability declined slightly principally as the Company utilized borrowings under its ABL Facility to redeem approximately $10.0 million of its 11.75% PIK Notes in January 2011.

“During the first quarter, we advanced our balance sheet de-leveraging strategy, primarily as a result of the equity offering and related debt reduction,” said Joe Troy, Chief Financial Officer. We paid off approximately $27.5 million of high cost 11.75% PIK Notes during the quarter and continued our focus on cost containment and asset efficiency. These actions and results all serve to support our goal of being well positioned to opportunistically capitalize on future growth opportunities.”

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 Ended March 31, 2011 and 2010

(In 000’s)

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 restructuring charges related to a plan of restructure which began in the second quarter of 2008 and concluded in the fourth quarter of 2010, as well as write-offs 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 leveraged 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 is especially important given the recent trends of increased merger and acquisition activity and financial restructurings within the industry, which has led to significant 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 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 the restructuring charges related to a plan of restructure which began in the second quarter of 2008 and concluded in 2010, write-off of debt issuance costs and other non-cash items such as non-cash stock-based compensation, to arrive at Adjusted EBITDA. 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.
