Quest Resource Reports 2014 Record Annual Revenue of $174.5 Million

Company reports positive annual EBITDAS, improved gross margins, and organic growth of 28%

Frisco, Texas – March 31, 2015 – Quest Resource Holding Corporation (Nasdaq: QRHC) (“Quest”), a leader in sustainability, recycling, and resource management, today announced financial results for the fourth quarter and year ended December 31, 2014.

Full-Year 2014 Highlights

"Fiscal 2014 was a very productive and successful year for Quest.  Due to strong organic growth, we more than doubled our prior year’s reported revenue to $174.5 million and generated positive EBITDAS of $1.4 million," commented Brian Dick, President and Chief Executive Officer of Quest. “During the year, we added a significant number of new customers thereby reducing our customer concentration risk."

“Federal and state regulatory measures, including more stringent control of material bound for disposal, continue to serve as a significant catalyst for our business,” continued Brian Dick. “We are well positioned to take advantage of growth opportunities as large national corporations look for more efficient and economical ways to dispose of waste, reduce their ecological footprint, and meet regulatory requirements.  Our asset-light business model affords us the ability to scale our business and quickly expand our service offerings, which provides us a competitive advantage in the market.”

Dick concluded, "Our performance during the fourth quarter and full year affirms our strategy. We believe we are well positioned to achieve our goal of $500 million in revenue with sustainable profitability in the next two to four years.”

Reconciliation of U.S. GAAP to Non-GAAP Financial Measures

In this press release, a certain non-GAAP financial measure, "Adjusted EBITDAS", is presented. From time-to-time, the company considers and uses the supplemental measures of operating performance in order to provide an improved understanding of underlying performance trends. The company believes it is useful to review, as applicable, both GAAP measures that include: (i) amortization of acquired intangible assets, (ii) acquisition-related costs, (iii) debt extinguishment costs, (iv) interest expense, (v) income taxes, (vi) depreciation and amortization, (vii) stock-based compensation expense, and the non-GAAP measures that exclude such information.  The company presents these non-GAAP measures because it considers them an important supplemental measure of its performance. The company's definition of these adjusted financial measures may differ from similarly named measures used by others. The company believes these measures facilitate operating performance comparisons from period to period by eliminating potential differences caused by the existence and timing of certain expense items that would not otherwise be apparent on a GAAP basis.  These non-GAAP measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for the company's GAAP measures.
