Clean Harbors, Inc. (“Clean Harbors”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced financial results for the second quarter ended June 30, 2021.

“Our second-quarter financial results far exceeded our guidance, as we benefitted from a steady flow of high-value waste streams into our disposal network and a strong performance within our Safety-Kleen Sustainability Solutions business,” said Alan S. McKim, Chairman, President and Chief Executive Officer. “These factors, coupled with a rebound in demand for many of our service offerings, drove substantial revenue growth and the highest second-quarter Adjusted EBITDA, Adjusted EBITDA margin and adjusted free cash flow in the Company’s history. Positive underlying market trends helped generate growth across all key lines of business.”

Second-Quarter 2021 Results

Revenues increased 30% to $926.5 million from $710.0 million in the same period of 2020. Income from operations grew 83% to $110.0 million from $60.2 million in the second quarter of 2020.

Net income was $67.1 million, or $1.22 per diluted share. This compares with net income of $29.0 million, or $0.52 per diluted share, for the same period in 2020. Adjusted for certain items in both periods, adjusted net income was $65.4 million, or $1.19 per diluted share, for the second quarter of 2021, compared with adjusted net income of $28.9 million, or $0.52 per diluted share, in the same period of 2020. (See reconciliation tables below)

Adjusted EBITDA (see description below) increased 36% to $187.8 million from $138.3 million in the same period of 2020. Benefits from Canadian and U.S. government assistance programs accounted for $5.2 million of contributions in the second quarter of 2021 compared with $23.4 million in the same period of 2020.

Q2 2021 Review

“Within our Environmental Services segment, revenues increased 18% from a year ago and 11% from Q1, fueled by growth in disposal and recycling volumes and a surge in Industrial Services activity,” McKim said. “Our incineration network continued to see strong demand, particularly for high-value waste streams, leading to utilization of 87% and a 5% increase in the average price per pound from a year ago. Our landfill business rebounded after several challenging quarters due to the pandemic, as volumes grew 13% and the average price increased 10%. Our Safety-Kleen Environmental branches continued their steady recovery, with quarterly parts washer services reaching 240,000 for the first time since the pandemic began. We also saw a meaningful contribution from our Industrial Services business with more than 50% growth driven by a backlog of deferred maintenance by customers during the past year.”

“Our Safety-Kleen Sustainability Solutions (SKSS) segment delivered extraordinary growth and profitability in the quarter, as our new segment continues to benefit from the combination of our waste oil collection with our SK Oil business. The supply shortages for base and blended oil, along with the impacts of IMO 2020, created a highly favorable pricing environment,” McKim said. “These market conditions led to the widening spread in our used oil market. Segment revenue was up 32% from the first quarter and more than doubled from a year ago, when the pandemic temporarily shut down more than half of our re-refining plants. Adjusted EBITDA in the segment doubled from Q1 and was up more than seven-fold from a year ago. Waste oil collections grew to 57 million gallons from 47 million in the first quarter and from 43 million a year ago.”

In late June, Clean Harbors announced the signing of a definitive agreement with Vertex Energy, Inc. (NASDAQ: VTNR) to acquire certain assets related to Vertex’s used motor oil collection and re-refinery business in an all-cash transaction for $140 million, subject to working capital and other adjustments. The acquisition is now expected to close toward the end of the current quarter of 2021 or shortly thereafter, subject to approval by U.S. regulators and Vertex shareholders, and other customary closing conditions.

Company Announces Planned Expansion of Incineration Network Capacity

Clean Harbors plans to construct a 70,000-ton hazardous waste incinerator at the Company’s plant in Kimball, Nebraska, which specializes in the destruction of hazardous and non-hazardous materials. The advanced new kiln will more than double annual incineration capacity at the 600-acre site to nearly 130,000 tons. Costing approximately $180 million to permit and construct over a four-year time frame, the new incinerator will add over 100 full-time workers upon completion.

“Clean Harbors is proud to make this investment in Nebraska to provide much needed environmental service capabilities to the Western U.S.,” McKim said. “We are excited to build upon our longtime relationship with the Kimball community, and confident these new jobs and increased business activity will benefit the economy of the region and the entire state.”

The Kimball expansion will be designed as North America’s most technologically advanced hazardous waste incinerator, equipped with world-class air emissions control technology that exceeds the Federal Clean Air Act’s most stringent air emissions standards. The plant will be only the second U.S. commercial hazardous waste incinerator to come online in the past 25 years, along with Clean Harbors El Dorado incinerator that opened in early 2017.

“While there is a lengthy permitting process and complex construction requirements, we are targeting having this facility operational in late 2024 and accepting waste in the first half of 2025,” McKim said. “We are confident that incineration demand – driven by the ongoing U.S. chemical and manufacturing expansion, and the continuing reduction of captive incinerators – will enable our additional capacity to be readily absorbed when it opens.”

Business Outlook and Financial Guidance

“We enter the second half of 2021 with considerable momentum across all our key markets, backed by a promising North American economic environment. We expect a record-setting financial year for the Company,” McKim concluded. “Within our Environmental Services segment, we see encouraging signs for steady waste volumes, project work and rising demand for our broad suite of service offerings. With the planned acquisition of HydroChemPSC, we will significantly bolster our capabilities within Industrial Services and Field Services while driving more volumes into our network. Within our SKSS segment, we see our used oil to base oil pricing spread extending until later in the year, and we will continue to see the benefits of separating out this segment. We will continue to capitalize on the opportunities afforded by these current market conditions, and look forward to adding the Vertex facilities, personnel and waste oil collection assets to this segment. 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 second-quarter financial performance and current market conditions, Clean Harbors is raising its 2021 guidance. For the year, the Company currently expects:

• Adjusted EBITDA in the range of $620 million to $650 million, based on anticipated GAAP net income in the range of $159 million to $193 million; and
• Adjusted free cash flow in the range of $285 million to $315 million, based on anticipated net cash from operating activities in the range of $475 million to $525 million.

For the third quarter of 2021, Clean Harbors expects Adjusted EBITDA to be at a level similar to or slightly above the third quarter of 2020, when the Company recognized $13.3 million from government assistance programs.

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 six months ended June 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 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 six months ended June 30, 2021 and 2020 (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 such as taxes paid in connection with divestitures and in 2020 have 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 six months ended June 30, 2021 and 2020 (in thousands):
