“First quarter financial results were in-line with our expectations and indicative of the temporary increase in costs and other factors we described last quarter, but not yet reflective of the performance-focused actions we are developing and implementing to improve operating efficiencies and financial performance. Through the decisive actions of our team, we were able to successfully complete a reduction in staffing levels and the sale of a non-core portion of our RWS business, both of which we expect will drive profitability improvements and more consistency in future financial results. We are committed to generating cash, increasing profitability and paying down debt, and

we believe we are on course to deliver ongoing improvements going forward,” said Dan M. Friedberg, Chairman of the Company’s Board of Directors.

Perry Moss, Quest’s Chief Executive Officer, said, "I am proud of the team’s commitment to our “performance culture” and we are working together to develop and implement short- and long-term initiatives. We are successfully adding and onboarding blue chip clients, continuing to provide differentiated value-added service to clients, while at the same time taking significant actions to drive efficiencies and accountability across the organization. The actions now underway are beginning to normalize operations and will help position Quest to drive positive long-term results. Importantly, we have a robust pipeline and a strong value proposition, which we expect to translate into new customers and share of wallet growth with existing customers.”

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 expectation that our reduction in staffing levels and the sale of a non-core portion of our RWS business will drive profitability improvements and more consistency in future financial results, and our belief that we are on course to deliver ongoing improvements going forward. 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. Our forward-looking statements are presented as of the date made, and we disclaim any duty to update such statements unless required by law to do so.
