Quest Resource Reports Third Quarter 2017 Financial Results

and Provides 2018 Outlook

THE COLONY, TX – November 14, 2017 -- Quest Resource Holding Corporation (NASDAQ: QRHC) ("Quest"), a leader in sustainability, recycling, and environmental resource services, today announced financial results for the third quarter ended September 30, 2017.

2017 Third Quarter Highlights

"Third quarter results were in line with our expectations, including cost improvements in our procurement operations.  In addition, our results reflect the positive impact of our strategic focus on growth in existing and new vertical markets that highlight Quest’s unique value propositions.  As planned, this strategy is driving significant improvement in profitability despite a temporary headwind on the top line from exiting low margin business,” said S. Ray Hatch, President and Chief Executive Officer. “We continue to build a significant pipeline of new business in the automotive service market, which is one of our more established verticals.  In addition, we continue to gain traction in new markets, including construction, demolition, and industrial, that we entered during the past year.  Our growth in areas such as these clearly demonstrates the scale and scope of our capabilities, and as such, we are increasingly being viewed by customers as a strategic partner, which is key in driving sustainable improvements in returns and shareholder value.”

Financial Outlook – Fiscal 2018

Mr. Hatch stated, “We are very excited about our prospects, outlook, and business opportunities going forward.  We have made tremendous progress with our strategic plan and will have completed the bulk of our transition by the end of 2017.  We expect the pace at which we add or renew business will accelerate.  We believe that this newly built foundation will allow for a sustainable business that can consistently grow both our revenue and net income.  

We believe that 2018 will see the new Quest. We anticipate that 2018 will be positively impacted by expansions with current customers and the addition of new customers, many of which should yield very positive effects. Based on the aforementioned, we expect revenue growth for 2018 to be between 10% and 15%, driving positive net income with estimated GAAP earnings between $2

million and $3 million, or GAAP earnings per share between $0.13 and $0.20, and estimated non-GAAP Adjusted EBITDA between $6 million and $7 million, or non-GAAP Adjusted EBITDA per share between $0.39 and $0.46.  Per share estimates are based upon the issued and outstanding common shares as of September 30, 2017.  Before the full effect of our strategic shift is reflected commencing in 2018, we anticipate that earnings for the transitional fourth quarter of 2017 will be relatively flat with the third quarter.”

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 expense, (iii) stock-based compensation expense, (iv) income tax expense, and (v) certain other adjustments, and (2) non-GAAP measures that exclude such items. 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.")
