•

Secured significant competitive wins; a new client in the restaurant end market and a geographic expansion with an existing client in the retail end market.

“We experienced a host of issues last year. These include a number of operational issues, an industrial sector slowdown, and client attrition; as well as challenges related to adding a record number of new clients and systems integration. We took decisive, well-documented actions to address these issues. These include reductions and additions to the management team, making cost reductions, selling an underperforming business line, and resetting financial covenants with our lenders. Since then, we have launched an intensive set of initiatives focused on driving short-term improvements and long-term operating and financial performance.

Our efforts to fundamentally improve our operations and produce more consistent financial results are on track. Sequential revenue comparisons reflect the sale of the non-core portion of our RWS business at the end of the first quarter and continued softness with clients in the industrial end market. Sequential growth in gross profit dollars, a decrease in SG&A costs and strong operating cash flow generation were all a direct result of the performance-focused actions we took earlier this year. Despite continued softness in the industrial end market, we are on track to continue to deliver improvements in the trajectory of the business,” said Dan M. Friedberg, Chairman of the Company’s Board of Directors.

Perry W. Moss, Quest’s Chief Executive Officer, said, “I believe a culture of performance and accountability is critical to the success of an organization. We are fundamentally changing Quest’s culture and we are already seeing positive results. Our team is embracing this data and KPI driven philosophy. Our Operational Excellence Initiatives are beginning to improve cash generation, improve efficiency, and reduce operational variability. In addition, we are strengthening vendor relationships and increasing employee satisfaction while maintaining high standards for client service; all of which will drive long-term shareholder value.

While we have been implementing operational improvements, we have also been actively pursuing growth initiatives. Macro uncertainties are causing prospective clients to delay decision making, which is slowing the pace of growth. Nevertheless, we are still winning new clients and adding new client opportunities to our pipeline. In addition, we are focused on expanding our share of wallet with existing clients. During the second quarter, our sales organization generated a significant win with a new client in the restaurant industry and a significant expansion of the geographic footprint with an existing retailer client. Both were competitive wins and reflective of our value proposition.”

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

In this press release, non-GAAP financial measures, “Adjusted EBITDA” and “Adjusted Net Income (Loss)” are presented. From time-to-time, Quest considers and uses these supplemental measures 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 these non-GAAP measures because it considers them an important supplemental measure of Quest’s performance. Quest’s definition of these adjusted financial measures may differ from similarly named measures used by others. Quest 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. (See attached tables “Reconciliation of Net Loss to Adjusted EBITDA” and “Adjusted Net Income (Loss) Per Share”).

Safe Harbor Statement

This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, which provides a “safe harbor” for such statements in certain circumstances. The forward-looking statements include, but are not limited to, our belief that our efforts to fundamentally improve our operations and produce more consistent financial results are on track, our belief that sequential growth in gross profit dollars, a decrease in SG&A costs and strong operating cash flow generation were all a direct result of the performance-focused actions we took earlier this year and our expectation that we are on track to continue to deliver improvements in the trajectory of the business. Actual events or results could differ materially from those discussed in the forward-looking statements as a result of various factors, including, but not limited to, competition in the environmental services industry, the impact of the current economic environment, interruptions to supply chains, commodity price fluctuations, and extended shut down of businesses, and other factors discussed in greater detail in our filings with the Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2024. You are cautioned not to place undue reliance on such statements and to consult our SEC filings for additional risks and uncertainties that may apply to our business and the ownership of our securities.
