Quest Resource Reports Fourth Quarter and Full Year 2016 Financial Results

Strategic initiatives demonstrate positive momentum in revenue and profits

Increase in Adjusted EBITDA for fourth consecutive quarter

Expects positive Adjusted EBITDA by the end of 2017

THE COLONY, TX -- 3/31/17 -- Quest Resource Holding Corporation (NASDAQ: QRHC) ("Quest"), a leader in sustainability, recycling, and environmental resource services, today announced financial results for the fourth quarter and fiscal year ended December 31, 2016.

Key recent and full year 2016 highlights:

“We demonstrated incremental improvement in revenue and reduced losses in the fourth quarter and expect to build on that momentum in 2017.  Our refocused and disciplined go-to-market strategy is highlighting our value-add and generating wins from both new and existing customers, better leveraging our national scale and broad scope of services.  In turn, our focused approach to customer acquisition should allow us to develop long-term recurring business,” said S. Ray Hatch, President and Chief Executive

Officer. “Clearly, 2016 was a year of significant change.  We believe the strategic initiatives we put in place are reinforcing the foundation for profitable growth and improved returns.  Our strategy of expanding existing markets, as well as entering into new industry verticals, is intended to accelerate our long-term growth rate and diversify our revenue streams.  In addition, our efforts to improve our business processes and our investments in technology are making it easier to onboard customers and subcontractors, as well as improving our efficiencies to enable us to better serve our customers and more rapidly and profitably scale our business.”  

Fourth Quarter and Full Year 2016 Financial Highlights:

“We grew our revenue year-over-year by 8% in 2016 and 2% in the fourth quarter, reflecting growth from both new and existing customers,” said Laurie Latham, Chief Financial Officer. “In the fourth quarter of 2016, gross margin improved 50 basis points and Adjusted EBITDA improved significantly compared with the prior year period.”

"We expect improved performance in 2017, reflecting our refocused go-to-market strategy and our efforts to enhance the value add of our services portfolio. Those initiatives, including our focused approach to customer acquisition, are expected to result in 1% to 2% improvement in gross margin and positive Adjusted EBITDA by the end of 2017," said Mr. Hatch.  “Long term, we expect our strategy will return the company to double-digit top-line growth.  In addition, we plan to show continued growth during the next several years and have established a three-to-five-year gross margin target in the low to mid-teens and an Adjusted EBITDA margin target of 4% to 6%.”

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

In this press release, a non-GAAP financial measure, "Adjusted EBITDA," is presented. From time-to-time, Quest considers and uses this supplemental measure of operating performance in order to provide an improved understanding of underlying performance trends. Quest believes it is useful to review, as applicable, both (1) GAAP measures that include (i) depreciation and amortization, (ii) interest and other expense, (iii) stock-based compensation expense, (iv) income tax expense, and (v) certain other adjustments, and (2) non-GAAP measures that exclude such information. Quest presents this non-GAAP measure because it considers it an important supplemental measure of Quest's performance. Quest's definition of this adjusted financial measure may differ from similarly named measures used by others. Quest believes this measure facilitates 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. This non-GAAP measure has limitations as an analytical tool and should not be considered in isolation or as a substitute for the company's GAAP measures. (See attached table "Reconciliation of Net Loss to Adjusted EBITDA.")
