2015 Annual Report CEO Letter to Quest Resource Holding Corporation Stockholders Dear Fellow Stockholders: I believe effective communication with the current and future stockholders of Quest is an important aspect of the leadership position entrusted to me. As I begin my first year with Quest, I wanted to share my initial observations and explain my plans to lead the company to future success. First, the positives. I have had an intense and instructive time immersing myself into our business, which has reinforced my initial enthusiasm when accepting the responsibility of leading this organization. The positives are numerous. o Enhanced media coverage and expanded regulations regarding climate change and population growth are driving concern about the environment, resource availability, and consumer expectations for sustainable business practices. o Industry trends will force companies to deal with the waste streams and recyclables generated by their businesses. o Against this background, Quest has deep market and industry knowledge, offers flexible and evolving solutions, and delivers measurable results for its customers. o Quest provides comprehensive, efficient, and cost-effective programs to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by businesses. o Quest’s disruptive and differentiated approach to waste and recycling is built on a strong foundation that gives Quest experience with a vast array of materials, a scalable service platform, and an infrastructure that provides impactful business intelligence to its customers. o Quest’s business model provides the flexibility to adjust effectively to a dynamic market and create customized solutions to fit its ever changing customer needs. o Probably most importantly, Quest has a team of experienced professionals that are dedicated to providing comprehensive, innovative, and cost-effective programs that reduce environmental negatives and a portfolio of world class customers that recognize the value Quest provides to their businesses. However, there are negatives as well. Our fiscal 2015 financial performance was totally unacceptable. We had lower than traditional margin contribution from a portion of our new business and challenges from changes in the market. My job and goal is to take advantage of our positives and lead us to superior financial performance. We are instituting a number of initiatives to substantially improve our financial performance. o Continue to expand our customer base and enhance our customer service and the value we bring to our customers; o Capture a larger portion of the commodity value of waste streams and recyclables; o Continue to develop innovative solutions to satisfy the needs of our customers; o o o Increase supply chain efficiencies to reduce cost of sales; Enhance our technology platform to foster our scalability and reduce general and administrative costs; and Improve our operating margins through a focus on our core strengths, more efficient services, and more positive contractual programs. We currently manage over 1.1 million tons of materials annually. We will continue to strive to be the premier solution provider to businesses for fiscal and ecological responsibility. We will focus on growing our business, improving our financial results, and enhancing our stockholder value. I am confident with our business model and our industry positioning. I look forward to implementing these initiatives and our strategy for Quest’s long-term success. However, I ask for your patience for our initiatives and strategy to show results. Sincerely, S.
