TAMPA, FL – February 20, 2013 – 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 $5.7 million, or $0.21 per diluted share, for the fourth quarter ended December 31, 2012, compared to net income of $5.5 million, or $0.22 per diluted share, in the fourth quarter ended December 31, 2011. Net income for the year ended December 31, 2012 was $50.1 million, or $1.84 per diluted share compared to net income of $23.4 million, or $0.96 per diluted share, for 2011.

Adjusted net income for the fourth quarter of 2012 was $3.0 million, or $0.11 per diluted share, compared to adjusted net income of $3.8 million, or $0.15 per diluted share, for the same quarter in 2011. Both periods are calculated by applying a normalized tax rate of 39% and excluding items not considered part of regular operating activities.

Adjusted net income for the fourth quarter of 2012 included the following pre-tax items which the Company does not consider to be part of its regular operating activities: costs associated with the previously disclosed termination and conversion of an independent affiliate relationship of $1.3 million, residual acquisition expenses of $0.6 million, the effects of Hurricane Sandy of $0.7 million, and net acquisition earnout benefit of ($2.6) million. A reconciliation of net income to adjusted net income for both periods is included in the attached financial exhibits.

“Our preliminary fourth quarter results were in line with the expectations we shared during our third quarter conference call,” stated Gary Enzor, Chief Executive Officer. “This past year was filled with transformative events such as multiple Energy Logistics acquisitions and a difficult but necessary affiliate transition, which pressured our organization on numerous fronts. Looking forward, our leadership team is optimistic about 2013 as we focus intensely on improving operating results, controlling our capital spending and delivering on our goal to generate strong earnings and returns for our shareholders.”

Fourth Quarter 2012 Consolidated Results

Total revenue for the fourth quarter of 2012 was $215.4 million, an increase of 20.5% versus the same quarter last year. Excluding fuel surcharges, revenue for the fourth quarter of 2012 increased by $34.3 million, or 22.8% compared to the prior-year period. This revenue improvement was driven by a $29.1 million increase from the Energy Logistics business resulting primarily from the three acquisitions completed in 2012, $2.2 million of growth from Intermodal, and a $3.0 million increase from the Chemical Logistics business.

Operating income for the fourth quarter of 2012 was $10.2 million, a decrease of $3.0 million versus the prior-year period, resulting from the aforementioned independent affiliate conversion, acquisition costs, and effects of Hurricane Sandy. Adjusting for these items and associated costs mentioned above, fourth quarter 2012 operating income would have been approximately $12.9 million, a decrease of $0.4 million versus the prior-year fourth quarter. Operating margins declined primarily as a result of higher equipment lease expense, increased insurance costs and lower asset utilization within the Energy and Chemical Logistics segments, as well as higher depreciation and amortization expenses from the Company’s recent acquisitions.

Adjusted EBITDA for the fourth quarter of 2012 was $20.3 million, up 13.4% compared to the fourth quarter of 2011, driven primarily by income from Energy Logistics acquisitions consummated in 2012 and increases in the Intermodal business. A reconciliation of net income to adjusted EBITDA for both periods is included in the attached financial exhibits.

Fourth Quarter 2012 Segment Results

Chemical Logistics

Revenues in the Chemical Logistics segment were $144.9 million in the fourth quarter of 2012, which was up 3.2% versus the fourth quarter of 2011. Excluding fuel surcharges, revenues increased $3.0 million, or 2.6%, primarily due to higher pricing and solid volumes. In addition, the Company was successful in retaining a significant portion of customer revenue from the affiliate conversion. Driver counts were also up 2.2% year-over-year due to focused recruiting and retention efforts.

Operating income in the Chemical Logistics segment was $6.1 million, down $2.8 million versus the comparable prior-year period, primarily due to approximately $1.6 million of affiliate conversion and acquisition charges. After adjusting for these items, operating income was down $1.2 million, as better pricing and volumes were offset by $1.1 million of higher equipment lease expense, $0.4 million of increased depreciation expenses from the affiliate asset acquisition in the fourth quarter and lower asset utilization primarily in the Northeast region of the U.S.

Intermodal

Revenues in the Intermodal segment were $31.4 million, up $2.8 million or 9.8% versus the prior-year period. Excluding fuel surcharges, revenues increased $2.2 million, or 8.6%, primarily due to continued strong demand for ISO container shipments and increases in brokerage, storage and repair business.

Operating income in the Intermodal segment was $3.8 million, up $0.5 million versus the prior-year period. The effects of Hurricane Sandy adversely impacted the Newark, NJ terminal with significant downtime and equipment damages, resulting in a $0.7 million loss of operating income. Excluding the effects of the storm, operating income for the intermodal segment would have improved by $1.2 million over the comparable prior-year period, primarily due to stronger revenues and expense control.

Energy Logistics

Revenues in the Energy Logistics segment were $39.1 million, up $29.4 million versus the prior-year period, as higher revenues from the three acquisitions consummated in 2012 were partially offset by a 49% decline in revenues from the Marcellus shale region. The decline in Marcellus revenue was driven primarily by lower natural gas prices and the independent affiliate conversion. Energy Logistics revenues in the fourth quarter were up 1.7% on a sequential basis versus the third quarter of 2012, as organic growth from the Company’s Texas and Oklahoma shale businesses more than offset seasonal declines within the Bakken and Marcellus regions.

Operating income in the Energy Logistics segment was $0.4 million, a decrease of $0.7 million versus the prior-year period. Excluding $0.4 million of affiliate conversion costs, year-over-year operating income declined $0.3 million, primarily due to $2.2 million of higher depreciation and amortization expenses, $1.2 million of reduced profitability within the Marcellus region, $0.6 million of expenses associated with new regional repair shop operations, and $0.2 million of equipment repositioning costs designed to improve future productivity. These impacts were partially offset by income associated with the 2012 acquisitions and growing affiliate operations in Texas and Oklahoma. Energy Logistics adjusted EBITDA for the fourth quarter was $3.4 million, up $1.9 million versus the prior-year period.

Summary

“Our Chemical and Intermodal businesses delivered solid fourth quarter results, and this trend has continued thus far into 2013,” said Gary Enzor, Chief Executive Officer. “Although our Energy Logistics business had a difficult quarter from an earnings perspective, our team held top line revenues versus the third quarter and is committed to improving operating profitability and optimizing the fleet across our footprint.”

Full Year 2012 Consolidated Results

Total revenue for the year ended December 31, 2012 was $842.1 million, an increase of 12.9% versus the same period last year. Excluding fuel surcharges, revenue increased 14.3% for the full year compared to the prior year primarily driven by the acquired Energy Logistics businesses.

Operating income for the year ended December 31, 2012 was $49.1 million, and included $10.9 million of expenses related to the following: costs associated with the termination of an independent affiliate relationship ($4.4 million), acquisition expenses ($4.0 million), the effects of Hurricane Sandy ($0.7 million), severance and lease termination charges ($1.0 million) and other legal settlements ($0.8 million). Operating income for the year ended December 31, 2011 was $57.7 million, and included a restructuring credit of $0.5 million. After adjusting for these items, operating income for the year ended December 31, 2012 would have been $60.0 million, an increase of $2.8 million, or 4.9% from operating income for the year ended December 31, 2011 of $57.2 million.

Adjusted net income for the year ended December 31, 2012 was $18.9 million, or $0.69 per diluted share, up 10.4% versus the prior year, and adjusted EBITDA for the year ended December 31, 2012 was $84.5 million, up $10.2 million, or 13.8% compared to the prior year. A reconciliation of net income to adjusted net income and adjusted EBITDA for both years is included in the attached financial exhibits.

Recent Transactions

As previously announced, the Company initiated a program during the fourth quarter of 2012 to repurchase up to $15 million of its common stock. During the fourth quarter of 2012, the Company repurchased 0.6 million shares for approximately $3.7 million. From January 1, 2013 through February 20, 2013, the Company repurchased an additional 0.5 million shares for approximately $3.2 million.

As disclosed in the Company’s third quarter earnings release, 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. On October 17, 2012 Quality acquired certain operating assets from this independent affiliate for approximately $17.1 million in cash. The Company does not expect to incur any significant future expense related to this transition.

Balance Sheet and Cash Flow

Borrowing availability under the Company’s ABL Facility was $55.2 million at December 31, 2012. This represents a decrease of $27.1 million versus December 31, 2011 as availability was utilized to help fund the three acquisitions consummated in 2012. During the fourth quarter of 2012, the Company aggressively disposed of idle assets generating $6.0 million to reduce outstanding ABL Facility borrowings. The Company expects to have sufficient borrowing availability under its ABL Facility to support its operating requirements in 2013.

Operating cash flow for the year ended December 31, 2012 was $17.0 million, compared with $35.4 million for the prior-year period. The decline was primarily due to the expected increase in working capital requirements from the newly acquired Energy Logistics businesses. Net capital expenditures for the year ended December 31, 2012 were $18.8 million, down $3.0 million from the prior year.

“During the quarter, we successfully contained capital and other spending, allowing us to utilize proceeds from asset sales and free cash flow to repurchase shares under our repurchase program,” said Joe Troy, Chief Financial Officer. “We will continue our strong focus on improving our operations, controlling capital and other expenditures, and utilizing our free cash flow to increase shareholder value.”

Mr. Troy continued, “In 2013 we will place enhanced emphasis 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 the Years Ended December 31, 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, Hurricane Sandy effects, earnout adjustments, 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, Hurricane Sandy effects, earnout adjustments, 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.
