Heckmann Corporation Announces Record Second Quarter 2011

Financial Results

Pittsburgh, PA — August 9, 2011 — Heckmann Corporation (NYSE: HEK, HEK.WS), a water solutions company focused on water issues, in particular, as water relates to oil and natural gas exploration and production, today announced financial results for the second quarter ended June 30, 2011.

“Our second quarter results reflect the growth in revenues and earnings that we believe are indicative of the enterprise we are building,” said Richard J. Heckmann, Chairman and CEO of Heckmann Corporation. “Even though two of our recent acquisitions were only included for 60 days and 15 days of the quarter, we still exceeded our financial expectations. As we have previously indicated, we are significantly expanding our produced and fresh water pipeline operations. Both are in the process of coming back on line and will add considerably to our future results. The run rate of our investments over the last year will also come into focus in the second half of this year. Accordingly, we have aggressively broadened our management team with experienced water industry executives, and we now have a company infrastructure capability far beyond our current size. And finally, we took delivery of the industry’s first LNG-powered semi tractor from Peterbilt Motors Company and we plan to add at least 200 additional LNG-powered vehicles over the next 12 months.”

Heckmann Corporation also today announced that it is negotiating to sell China Water & Drinks, Inc., which forms the Company’s bottled water business segment. Accordingly, in the third quarter of 2011, the Company will classify China Water & Drinks as a discontinued operation and will reclassify its comparable period results to reflect this change.

“We think that China Water & Drinks has a lot of potential for growth in China, but we believe the company and its loyal employees would be better positioned for growth with another company dedicated to growth in Asia,” Mr. Heckmann stated. “By focusing on our rapidly growing U.S. water business and the domestic market for integrated water services in the oil and natural gas sectors, combined with the improving operating leverage we expect to gain as our run rate continues to grow, we are confident that our guidance of over $150 million in revenues and $40 million in adjusted EBITDA will be achieved, excluding operations from China Water & Drinks.”

Operational Update – Water Solutions for Energy Development

In the second quarter of 2011, the Company’s produced water pipeline, which was under construction for an expansion and extension, began to return to service. In the second quarter, the pipeline averaged 17,000 barrels per day throughput and was not profitable. Heckmann expects the pipeline to double its throughput and achieve solid profitability in the third quarter of 2011, and to significantly increase throughput in the fourth quarter of 2011.

The 40-mile fresh water pipeline conversion along HWR’s current right-of-ways connecting its Sabine River water source to customers’ operations in the Haynesville Shale area is progressing. The Company expects the pipeline to enter service and be profitable in the fourth quarter of 2011 with capacity to deliver up to 60,000 barrels per day of fresh water for exploration and production.

Heckmann currently owns and operates 23 disposal wells with a permitted capacity of approximately 368,000 barrels per day. The Company owns and operates a fleet of approximately 400 trucks, 433 trailers and 900 frac tanks. Heckmann estimates that in the third quarter of 2011 it will add approximately 100 conventional diesel trucks and 110 frac tanks to its fleet. Heckmann also expects to add approximately 70 LNG-powered trucks in the second half of 2011, with additional diesel trucks and frac tanks in the fourth quarter of 2011.

At the end of the second quarter of 2011, Heckmann’s domestic employment had increased to approximately 886 employees from 30 employees in the second quarter of 2010.

About Non-GAAP Financial Measures

This press release contains non-GAAP financial measures as defined by the rules and regulations of the United States Securities and Exchange Commission. A non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operations, balance sheets, or statements of cash flows of the Company; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. Reconciliations of these non-GAAP financial measures to their comparable GAAP financial measures are included in the attached financial tables.

These non-GAAP financial measures are provided because management of the Company uses these financial measures in maintaining and evaluating the Company’s ongoing financial results and trends. Management uses this non-GAAP information as an indicator of business performance, and evaluates overall management with respect to such indicators. Management believes that excluding items such as acquisition expenses, amortization of intangible assets and stock-based compensation, among other items that are inconsistent in amount and frequency (as with acquisition expenses), or determined pursuant to complex formulas that incorporate factors, such as market volatility, that are beyond our control (as with stock-based compensation), for purposes of calculating these non-GAAP financial measures facilitates a more meaningful evaluation of the Company’s current operating performance and comparisons to the past and future operating performance. The Company believes that providing non-GAAP financial measures such as EBITDA, adjusted EBITDA, adjusted net income, and adjusted net income per share, in addition to related GAAP financial measures, provides investors with greater transparency to the information used by the Company’s management in its financial and operational decision-making. These non-GAAP measures should be considered in addition to, but not as a substitute for, measures of financial performance prepared in accordance with GAAP.
