NORWELL, Mass. – November 2, 2022 – Clean Harbors, Inc. (“Clean Harbors”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced financial results for the third quarter ended September 30, 2022.

“In the third quarter, favorable market dynamics combined with the quality of our offerings drove continued broad-based demand for our comprehensive suite of environmental services and sustainable products,” said Alan S. McKim, Chairman, President and Chief Executive Officer. “We extended our strong 2022 performance with a revenue increase of 43%, growth in Adjusted EBITDA of 67% and a corresponding improvement in Adjusted EBITDA margins of 310 basis points to 22.6%. Our positive results were driven by profitable growth contributions from both of our operating segments. Most importantly, our safety performance in the quarter and year to date was the best in our history with a Total Recordable Incident Rate (TRIR) of just 0.74 through nine months – far below our annual goal of less than 1.0.”

Revenues increased 43% to $1.36 billion from $951.5 million in the same period of 2021. Income from operations nearly doubled to $209.1 million from $104.8 million in the third quarter of 2021.

Net income was $135.8 million, or $2.50 per diluted share. This compared with net income of $65.4 million, or $1.20 per diluted share, for the same period in 2021. Adjusted for certain items in both periods, adjusted net income was $132.4 million, or $2.43 per diluted share, for the third quarter of 2022, compared with adjusted net income of $62.2 million, or $1.14 per diluted share, for the same period of 2021. (See reconciliation tables below).

Adjusted EBITDA (see description below) increased 67% to $308.6 million from $185.1 million in the same period of 2021.

“Environmental Services (ES) revenues increased 46% year-over-year, and Adjusted EBITDA in the segment rose 57%. Our profitable growth was driven by the October 2021 acquisition of HydroChemPSC (HPC), robust volumes of high-value waste streams, pricing initiatives to combat inflation and strong utilization of people and equipment across all our service businesses,” McKim said.

“Utilization of our incinerator network was a healthy 86% in the quarter, up from 82% a year ago. Average incineration pricing rose 10% from a year ago, reflecting price increases and the impact of higher-value waste streams. Landfill volumes increased 38% as we continued to capture more remediation and waste projects. On the strength of sizeable summer activity, our Industrial Services business performed well in the quarter. Safety-Kleen Environmental revenue grew 23% as its core service offerings remained in demand, particularly in the automotive service vertical. Field Services delivered a 29% increase in revenue through the addition of HPC’s utilities business and a variety of local emergency response projects throughout our network. In addition to higher revenue, ES also benefitted from cost-control initiatives and operational efficiencies, resulting in segment EBITDA margin improving 170 basis points from a year ago.

“Safety-Kleen Sustainability Solutions (SKSS) delivered record quarterly results as revenues grew 34% in the third quarter, and Adjusted EBITDA climbed 46% from a year ago,” McKim said. “Demand for our base oil was high in Q3 and our network of re-refineries ran well, including the new Georgia plant we acquired in June. We also achieved growth across all of our recycling services offered in this segment including oil filter collection and antifreeze recycling. Waste oil collections remained strong at 62 million gallons. Since its formation less than two years ago, our SKSS team has proven adept at actively managing the front end of our re-refining spread to maximize profitability. The SKSS segment achieved its record performance in the quarter despite the fact that our blended volumes were severely limited by supply chain disruptions resulting from an industrywide additive shortage. The additive industry is beginning to recover, and we expect our blended volumes to increase in 2023 as that remains part of our long-term growth strategy for this segment.”

“Looking ahead, we expect to close out 2022 with a strong fourth-quarter performance,” McKim said. “Within Environmental Services, we continue to see a record backlog of waste and healthy demand for our network of disposal and recycling assets. We anticipate a solid finish to the year through a combination of base business and project work. Our service businesses are all entering the final quarter of the year with good momentum. We are continuing to hire as rapidly as possible across our Environmental Services segment to facilitate additional growth while also reducing our third-party spend.

“Within SKSS, the record results we are achieving this year demonstrate how well we are managing both ends of our re-refining spread,” McKim said. “We are seeing growing interest in our sustainable products, including our recently launched KLEEN+ brand, as customers seek ESG friendly solutions. We are confident that the inherent value of our base oil will increase in the years ahead. On the front end of our re-refining spread, we are continuing to collect the volumes needed for our plants at better rates due to the long-term market impact of IMO 2020, the internal changes we made to the organization, and continuous improvements in our systems and transportation.

“Given our year-to-date performance, we are raising our annual Adjusted EBITDA guidance to more than $1 billion, which reflects the acceleration of demand for our environmentally focused services and products. Our revenue is growing more rapidly than we had expected, which is driving higher than anticipated working capital needs.

In addition, we are carrying a higher level of critical inventories to ensure we stay ahead of global supply chain shortages. Therefore, we are reducing our adjusted free cash flow guidance to reflect the timing of working capital from those two factors. With the ongoing backdrop of high inflation and interest rate hikes, we are continuing to execute on our strategies for pricing, cost mitigation and operational efficiencies to drive further margin improvement. We anticipate leveraging the strengths of both operating segments to achieve record top- and bottom-line results in 2022,” McKim concluded.

Based on its year-to-date performance and current market conditions, Clean Harbors is revising its 2022 Adjusted EBITDA and adjusted free cash flow guidance. For the year, the Company now expects:

•Adjusted EBITDA in the range of $1.010 billion to $1.030 billion, or a midpoint of $1.020 billion. This range is based on anticipated GAAP net income in the range of $387 million to $410 million; and

•Adjusted free cash flow in the range of $260 million to $290 million, or a midpoint of $275 million. This range is based on anticipated net cash from operating activities in the range of $585 million to $635 million.

Clean Harbors reports Adjusted EBITDA, which is a non-GAAP financial measure and should not be considered as an alternative to net income or other measurements under generally accepted accounting principles (GAAP), but viewed only as a supplement to those measurements. Adjusted EBITDA is not calculated identically by all companies, and therefore the Company’s measurement of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Clean Harbors believes that Adjusted EBITDA provides additional useful information to investors since the Company’s loan covenants are based upon levels of Adjusted EBITDA achieved and management routinely evaluates the performance of its businesses based upon levels of Adjusted EBITDA. The Company defines Adjusted EBITDA in accordance with its existing revolving credit agreement, as described in the following reconciliation showing the differences between reported net income and Adjusted EBITDA for the three and nine months ended September 30, 2022 and 2021 (in thousands, except percentages):

This press release includes a discussion of net income and earnings per share adjusted for the impacts of tax-related valuation allowances and other items as identified in the reconciliations provided below. The Company believes that discussion of these additional non-GAAP measures provides investors with meaningful comparisons of current results to prior periods’ results by excluding items that the Company does not believe reflect its fundamental business performance. The following shows the difference between net income and adjusted net income, and the difference between earnings per share and adjusted earnings per share, for the three and nine months ended September 30, 2022 and 2021 (in thousands, except per share amounts):

Clean Harbors reports adjusted free cash flow, which it considers to be a measurement of liquidity that provides useful information to investors about its ability to generate cash. The Company defines adjusted free cash flow as net cash from operating activities excluding cash impacts of items derived from non-operating activities, less additions to property, plant and equipment plus proceeds from sale and disposal of fixed assets. The Company excludes cash impacts of items derived from non-operating activities such as taxes paid in connection with divestitures. Adjusted free cash flow should not be considered an alternative to net cash from operating activities or other measurements under GAAP. Adjusted free cash flow is not calculated identically by all companies, and therefore the Company’s measurement of adjusted free cash flow may not be comparable to similarly titled measures reported by other companies.

An itemized reconciliation between net cash from operating activities and adjusted free cash flow is as follows for the three and nine months ended September 30, 2022 and 2021 (in thousands):
