NORWELL, Mass. – March 1, 2023 – Clean Harbors, Inc. (“Clean Harbors”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced financial results for the fourth quarter and year ended December 31, 2022.

“We concluded a record 2022 with strong fourth-quarter results, led by our Environmental Services segment,” said Alan S. McKim, Chairman, President and Chief Executive Officer. “Favorable market dynamics continued to drive considerable demand for our disposal and recycling assets, while our broad range of service offerings also performed well in the quarter. Revenues grew $159 million from a combination of pricing and volume. By leveraging that growth and controlling our costs, we delivered Q4 Adjusted EBITDA growth of 29% and improved our margins by 190 basis points from the same period a year ago.”

Fourth-Quarter Results
Revenues increased 14% to $1.28 billion from $1.12 billion in the same period of 2021. Income from operations grew 55% to $127.4 million from $82.2 million in the fourth quarter of 2021.

Net income was $82.5 million, or $1.52 per diluted share. This compared with net income of $49.0 million, or $0.90 per diluted share, for the same period in 2021. Adjusted for certain items in both periods, adjusted net income was $78.5 million, or $1.44 per diluted share, for the fourth quarter of 2022, compared with adjusted net income of $48.6 million, or $0.89 per diluted share, for the same period of 2021. (See reconciliation tables below). Net income and adjusted net income results for the fourth quarter of 2022 included pre-tax integration and severance costs of $0.3 million. Comparable costs in the fourth quarter of 2021 were $8.6 million, reflecting costs associated with the HydroChemPSC acquisition, which was completed in October 2021.

Adjusted EBITDA (see description below) increased 29% to $224.2 million from $174.3 million in the same period of 2021.

Q4 2022 Segment Review
“Environmental Services (ES) revenues increased 15% year-over-year, and Adjusted EBITDA in the segment rose 35% resulting in a 22.9% margin for the quarter which represents a 340-basis-point improvement over the prior year quarter,” McKim said. “Utilization of our incinerator network was lower than recent quarters at 84% because of unplanned outages at several locations due to severe weather experienced in December. Volumes of higher-value waste streams and overall incineration demand remained strong resulting in a 21% increase in average incineration pricing from a year ago. Landfill volumes increased 28%, along with a small increase in average pricing, as we continued to capture more remediation and waste projects. Our Industrial Services business performed well in the quarter and closed out the year strong with increased customer needs related to the severe weather. Safety-Kleen Environmental revenue grew more than 20% for the third consecutive quarter; demand for its core offerings has now surpassed pre-pandemic levels. Field Services revenue was up 8% from pricing and branch growth initiatives.

“Safety-Kleen Sustainability Solutions (SKSS) revenues grew 9% in the fourth quarter, while Adjusted EBITDA decreased 12% from a year ago,” McKim said. “We experienced a seasonal slowdown in base oil demand in the fourth quarter after a record-breaking third quarter. While our re-refinery spread remained wide, we sold lower volumes of both base oil and blended products as customers depleted their inventories to close out the year. Segment profitability was affected by overall revenue mix and severe weather at multiple locations, which impacted production and resulted in higher costs. We also made investments in the business to accelerate lubricant sales in 2023 and beyond. Waste oil collections were strong in the quarter at 57 million gallons. The new Georgia plant we acquired in June has been running well after initiating multiple throughput enhancements.”

2022 Financial Results
Clean Harbors’ revenues increased 36% to $5.17 billion compared with $3.81 billion in 2021. Income from operations increased 82% to $634.7 million from $347.9 million in 2021.

Net income was $411.7 million, or $7.56 per diluted share, compared with net income of $203.2 million, or $3.71 per diluted share for 2021. Adjusted for certain items in both periods, the Company reported adjusted net income for 2022 of $389.5 million, or $7.15 per diluted share, compared with adjusted net income of $199.6 million, or $3.64 per diluted share, for 2021. (See reconciliation table below). Net income and adjusted net income results for 2022 included pre-tax integration and severance costs of $3.0 million. Comparable costs in 2021 were $19.7 million, with the HPC acquisition representing the largest contributing factor.

Adjusted EBITDA (see description below) increased 51% to $1,022.1 million, compared with Adjusted EBITDA of $676.6 million in 2021, which included $12.0 million of benefits from government assistance

programs. The Company generated adjusted free cash flow of $289.9 million in 2022, compared with $326.3 million in 2021. The decrease is largely attributable to higher working capital related to our rapid growth and increased capital expenditures including $45 million of spend associated with the construction of our new incinerator in Nebraska.

“2022 was another terrific year for Clean Harbors, from our outstanding safety results to our record financial performance and notable operating achievements,” said McKim. “In safety, we vastly exceeded our goal of delivering a Total Recordable Incident Rate (TRIR) of below 1.0. We concluded the year with a TRIR of 0.73, which is our best annual safety performance by a wide margin, as the team worked diligently to keep themselves and their colleagues safe. Financially, we expanded our Adjusted EBITDA margins by 200 basis points on the strength of a 36% top-line increase and 51% Adjusted EBITDA growth. We generated more than one billion dollars of Adjusted EBITDA for the first time in our history – while improving our ROIC for the fifth consecutive year. On the operational side, we successfully integrated HPC, advanced construction of our next incinerator, acquired our eighth re-refinery facility, launched our KLEEN+ brand in the base oil market, significantly lowered voluntary turnover while increasing the hiring of billable headcount, and issued our ground-breaking PFAS incineration study.”

Business Outlook and Financial Guidance
“We enter 2023 with momentum across all our key businesses,” McKim said. “Within ES, our record backlog of waste and deferred revenue grew during the quarter, which positions us well for this year. Based on the diversity of our customer base, we expect healthy demand for our network of disposal and recycling assets to continue in 2023. Our service businesses all registered robust growth in 2022 and, with the expansion of our billable headcount throughout the year, we should benefit from those hires in 2023. We also expect ample project opportunities this year as monies from the U.S infrastructure bill, the CHIPS act and other programs supporting domestic spending are released. In addition, we expect to benefit from the manufacturing reshoring trend.
“Within SKSS, we continue to closely manage both ends of our re-refining spread and collect the waste oil volumes needed to support our plants. While base oil demand slowed from heightened summer levels in the fourth quarter, we are beginning to experience the normal seasonal pickup in the early part of this year and are confident overall market conditions will remain favorable for 2023. We also see numerous opportunities to enhance our profitability in this segment including raising production from 2022 levels, increasing sales of blended products and capitalizing on growing interest in our sustainable products. Our new KLEEN+ base oil brand is helping to facilitate discussions with customers seeking solutions that lower the environmental impact of their automotive and industrial lubricant products,” McKim concluded.

For the first quarter of 2023, Clean Harbors expects Adjusted EBITDA to increase approximately 20% from the prior year.

For full-year 2023, Clean Harbors expects:
•Adjusted EBITDA in the range of $1,010 million to $1,050 million or a midpoint of $1,030 million. This range is based on anticipated GAAP net income in the range of $355 million to $391 million; and
•Adjusted free cash flow in the range of $305 million to $345 million, or a midpoint of $325 million, based on anticipated net cash from operating activities in the range of $705 million to $765 million.

Non-GAAP Results
Clean Harbors reports Adjusted EBITDA, which is a non-GAAP financial measure and should not be considered 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 twelve months ended December 31, 2022 and 2021 (in thousands, except percentages):

This press release includes a discussion of net income and earnings per share adjusted for the loss on early extinguishment of debt, gain on sale of business and 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 twelve months ended December 31, 2022 and 2021 (in thousands, except per share amounts):

Adjusted Free Cash Flow Reconciliation
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. 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 twelve months ended December 31, 2022 and 2021 (in thousands):
