Clean Harbors Announces Third-Quarter 2021 Financial Results

Reports 22% Increase in Q3 Revenues to $951.5 Million
Delivers Q3 Net Income of $65.4 Million, or EPS of $1.20, with Adjusted EPS of $1.14
Achieves 10% Growth in Q3 Adjusted EBITDA to $185.1 Million With Margin of 19.5%
Raises Full-Year 2021 Adjusted EBITDA and Adjusted Free Cash Flow Guidance

NORWELL, Mass. – November 3, 2021 – 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, 2021.

“In the quarter, we experienced a continuation of many of the favorable trends that have supported our business all year – substantial volumes of high-value waste streams for disposal, a wider than normal spread in the re-refining market and steadily growing demand for many of our service businesses,” said Alan S. McKim, Chairman, President and Chief Executive Officer. “These factors enabled us to exceed our guidance and deliver the highest quarterly revenue in Company history. In a market environment disrupted by supply chain bottlenecks, labor shortages and inflationary cost pressures, our financial results reflect the strong execution by our leadership team in managing through challenging conditions.”

Third-Quarter 2021 Results
Revenues increased 22% to $951.5 million from $779.3 million in the same period of 2020. Income from operations grew 25% to $104.8 million from $83.9 million in the third quarter of 2020.

Net income was $65.4 million, or $1.20 per diluted share. This compares with net income of $54.9 million, or $0.99 per diluted share, for the same period in 2020. Adjusted for certain items in both periods, adjusted net income was $62.2 million, or $1.14 per diluted share, for the third quarter of 2021, compared with adjusted net income of $49.9 million, or $0.90 per diluted share, in the same period of 2020. (See reconciliation tables below) Net income and adjusted net income results for the third quarter of 2021 included pre-tax integration and severance costs of $6.2 million, primarily related to the acquisition of HydroChemPSC. Comparable costs in the third quarter of 2020 were $1.8 million.

Adjusted EBITDA (see description below) increased 10% to $185.1 million from $167.8 million in the same period of 2020. Benefits from Canadian pandemic programs accounted for $1.1 million of contributions in the third quarter of 2021, compared with $13.3 million in benefits from both Canadian and U.S. government programs in the same period of 2020.

Q3 2021 Review
“Revenues in our Environmental Services segment increased 15%, reflecting strong demand for our disposal and recycling services, as well as growth in many of our service businesses,” McKim said. “Our incineration network produced utilization of 82%, compared with 80% in the prior year, driven by record drum volumes and direct burn streams. We raised prices to help offset cost increases and focused our available capacity on high-value waste streams, resulting in an 18% increase in the average price per pound from a year ago. Landfill volumes were down 5% due to lower project activity, but our average price per ton increased 17% due to the mix of waste. Our Safety-Kleen Environmental branches registered another solid quarter, with most core service offerings trending up. For the second consecutive quarter we saw a sizeable increase in our Industrial Services business, as customers continue to address the substantial backlog of deferred maintenance related to the pandemic.”

“With industry dynamics on the supply side remaining favorable, our Safety-Kleen Sustainability Solutions (SKSS) segment again delivered exceptional results. Revenues grew 60% from a year ago while Adjusted EBITDA more than doubled,” McKim said. “Demand for our base and blended oil was high throughout the quarter, leading to a healthy pricing environment. Market conditions, including the underlying impact of IMO 2020, enabled us to deliver the widest re-refinery spread in our history. Waste oil collections were strong at 60 million gallons, up from 50 million a year ago.”

Business Outlook and Financial Guidance
“The positive demand environment in North America that we have witnessed all year is showing no signs of slowing as we enter the final quarter of 2021,” McKim said. “Customers continue to rely on Clean Harbors for their environmental and industrial needs, and to be their sustainability partner. We expect to conclude the year with a strong finish in all our core lines of business. In early October, we completed the acquisition of HydroChemPSC (“HPC”), which we believe will accelerate our growth momentum as we take a leadership position in the U.S. Industrial Services market. Within our Environmental Services segment, we have a considerable backlog of waste volumes within our network and at our customers’ sites. Our Field Services business has transitioned well from COVID-19 decontamination work back to its core operations, and the addition of HPC’s utility group will expand our scale. The main challenge for this segment in the coming months will be navigating through the ongoing headwinds of cost inflation, supply chain disruption, labor availability and transportation-related limitations. We intend to accelerate the pricing initiatives we have underway to combat these cost and labor challenges.
“Within our SKSS segment, the wide spread between used oil to base oil pricing has continued into the back half of the year based on market conditions. The changes we have made in creating the SKSS business will also continue to benefit us going forward,” McKim concluded. “Overall, we continue to maintain a favorable outlook in both of our segments for the remainder of the year and into 2022.”

Based on its third-quarter financial performance, completion of the HPC acquisition and current market conditions, Clean Harbors is raising its 2021 guidance. For the year, the Company now expects:
Adjusted EBITDA in the range of $655 million to $675 million, including an approximately $15 million contribution from HPC. This range is based on anticipated GAAP net income in the range of $171 million to $196 million; and
Adjusted free cash flow in the range of $310 million to $330 million, based on anticipated net cash from operating activities in the range of $500 million to $540 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 nine months ended September 30, 2021 and 2020 (in thousands, except percentages):

This press release includes a discussion of net income and earnings per share adjusted for the loss on sale of businesses 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 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 such as taxes paid in connection with divestitures and in 2020 also excluded cash paid in connection with the purchase of its corporate headquarters and certain capital improvements to the site as these expenditures are considered one-time in nature. 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, 2021 and 2020 (in thousands):
