Quest Resource Reports First Quarter 2016 Results

The Colony, Texas – May 16, 2016 – Quest Resource Holding Corporation (Nasdaq: QRHC) (“Quest”), a leader in sustainability, recycling, and resource management, today announced financial results for the quarter ended March 31, 2016.

First Quarter 2016 Operational Highlights

Ray Hatch, President and Chief Executive Officer, commented, "I chose to join and lead Quest because of its great potential.  Our brand resonates in the marketplace, in particular with Fortune 100 companies, because our services are a win for our customers.  Our quarterly revenue increase of 14.4%, user service locations growth of 15,000, and continually strong sales pipeline demonstrate the market’s positive reception of our value proposition."

Mr. Hatch continued, "While Quest continues to grow, we must better capitalize on our strengths.  We have revised our account acquisition strategy to focus on customers that desire a full complement of our service offerings.  Specialty and complex services, rather than commodity tasks, will drive our gross margin improvement.  Our business platform provides the ability to expand our service offerings into almost any service our customers demand as driven by the market."

"I want our stockholders to know that addressing our operational and financial performance is my absolutely urgent and top priority," added Mr. Hatch. "I believe achieving our goals of profitable growth, expanded service lines, targeted acquisitions, and innovation opportunities will separate us from our competition and drive higher value for our company."

First Quarter 2016 Financial Results

Revenue

For the quarter ended March 31, 2016, revenue was $45.8 million, an increase of $5.8 million, or 14.4%, compared with $40.0 million for the quarter ended March 31, 2015.  The increase was primarily due to a combination of new and expanded services with customers added after the first quarter of 2015, with user service locations expanding to approximately 95,000 as of March 31, 2016 compared with 80,000 as of March 31, 2015.  

Cost of Revenue and Gross Profit

Cost of revenue increased $5.6 million to $42.3 million for the quarter ended March 31, 2016 from $36.7 million for the quarter ended March 31, 2015.  The increase related primarily to the cost of servicing the new and expanded services with customers added in 2015. Gross profit increased $200,000 to $3.5 million from $3.3 million.

Operating Expenses

For the quarter ended March 31, 2016, operating expenses increased $918,000 to $5.7 million from $4.8 million for the comparable quarter in 2015. The increase related primarily to an increase in stock related compensation of $254,000 and in selling, general, and administrative expenses of approximately $400,000 for integrating and servicing an increased number of customer locations in the quarter ended March 31, 2016.  Operating expenses also included depreciation and amortization of $1.0 million and $980,000 for the three months ended March 31, 2016 and 2015, respectively.  This $20,000 increase related primarily to amortization of software development costs capitalized subsequent to the first quarter of 2015.

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, 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 GAAP measures that include (i) depreciation and amortization, (ii) interest and other expense, (iii) stock-based compensation expense, and (iv) income tax expense, and 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 EBITDAS.")
