• Posts 12% Q3 Revenue Increase to $1.53 Billion, Led by Strength in Field Services
• Generates 26% Q3 Net Income Growth to $115.2 Million, or EPS of $2.12
• Achieves 18% Growth in Q3 Adjusted EBITDA to $301.8 Million with Margin of 19.7%
• Revises Full-Year 2024 Adjusted EBITDA and Adjusted Free Cash Flow Guidance
• Commercial Launch of Kimball, Nebraska Incinerator Planned for November

Clean Harbors, Inc. (“Clean Harbors” or the “Company”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced financial results for the third quarter ended September 30, 2024.

“We delivered profitable growth in both our operating segments while improving our consolidated Adjusted EBITDA margin by 100 basis points from the same period a year ago,” said Mike Battles, Co-Chief Executive Officer. “Underlying demand remained healthy across our Environmental Services (ES) segment. Despite higher Adjusted EBITDA, our Safety-Kleen Sustainability Solutions (SKSS) segment results reflected softer-than-expected demand and pricing of base oil and lubricants throughout the quarter with a more meaningful decline in September. We continue to prioritize safety with industry-leading results, achieving a Total Recordable Incident Rate (TRIR) of 0.69 year-to-date through September.”

Third-Quarter 2024 Results

Revenues grew 12% to $1.53 billion, compared with $1.37 billion in the same period of 2023. Income from operations increased 25% to $192.3 million, compared with $154.4 million in the third quarter of 2023.

Net income was up 26% to $115.2 million, or $2.12 per diluted share, compared with $91.3 million, or $1.68 per diluted share, for the same period in 2023.

Adjusted EBITDA (see description and reconciliation below) grew 18% to $301.8 million, compared with $255.0 million in the same period of 2023.

Third-Quarter 2024 Segment Review

“Our ES segment achieved a 13% increase in revenue and 15% growth in Adjusted EBITDA, which generated a 40-basis point improvement in segment margin. The third quarter marks our tenth consecutive quarter of year-over-year margin improvement in the ES segment,” said Eric Gerstenberg, Co-Chief Executive Officer. “ES growth was led by Field Services, which grew 68%, reflecting the HEPACO acquisition earlier this year and healthy organic growth in our legacy business. Technical Services revenue grew 8% on higher network volumes and pricing. Incineration utilization was 89% for the quarter, up from 86% in the same period a year ago. Average incineration pricing increased 6%. Safety-Kleen Environmental Services posted another consistent performance with 8% revenue growth in the ES segment. Our Industrial Services business experienced a difficult environment in Q3 resulting from weakness in the U.S. refinery space, where we saw work deferred and fall turnarounds scaled back given industry challenges in that vertical.”

“SKSS results improved from the third quarter a year ago. Revenues grew 6%, reflecting the contribution of our Noble Oil acquisition in March, while Adjusted EBITDA increased 32%,” said Battles. “However, current supply overhangs in the base oil market resulted in lower demand and pricing pressure, which caused a weaker-than-anticipated EBITDA performance this quarter.”

Business Outlook and Financial Guidance

“As we enter the final quarter of 2024, the overall demand environment in North America is healthy, and the outlook for our ES segment is positive,” Gerstenberg said. “Favorable market dynamics, including reshoring, infrastructure spending, PFAS, and other regulatory changes should continue to fuel growth opportunities for Clean Harbors. We are meeting these opportunities with new capacity and capabilities. The commercial launch of our new incinerator in Kimball, Nebraska is scheduled for November, providing an essential outlet for additional hazardous waste volumes as it ramps up over the next 12-18 months. On the services side, the addition of HEPACO’s emergency response capabilities creates a foundation for continued growth in Field Services. We also expect our Technical Services and SK Environmental businesses to grow steadily, feeding volumes into Kimball and the other facilities in our network. In Industrial Services, we are taking actions to counter the weakness in fall turnarounds and look to return that business to revenue growth in 2025.”

“Within SKSS, we remain committed to stabilizing our business amidst the current pricing challenges and weak demand for base oil. We are taking decisive actions to reduce production and collection costs while also pursuing growth initiatives in Group III, blended sales, and our partnership with Castrol. These programs have the potential to reduce the carbon footprints of businesses significantly, and we believe they will gain traction as more customers look to Safety-Kleen as their sustainability partner in the coming years,” Battles concluded. “Overall, despite some market obstacles related to base oil and refining customers, we expect to end 2024 with strong momentum across our network of disposal facilities and service offerings giving us a positive trajectory into 2025.”

Based on its third-quarter performance and current forecast, Clean Harbors revised its full-year 2024 guidance and now expects:

• Adjusted EBITDA in the range of $1.10 billion to $1.12 billion, or a midpoint of $1.11 billion, which represents 10% growth year-over-year. This Adjusted EBITDA range is based on anticipated GAAP net income in the range of $375 million to $395 million.
• Adjusted free cash flow in the range of $280 million to $320 million, or a midpoint of $300 million, which includes spending related to the Kimball incinerator and the Company’s Baltimore expansion. The Company is revising this range due to its new Adjusted EBITDA guidance and increased short-term working capital levels. This new range is based on anticipated net cash from operating activities in the range of $680 million to $750 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 because the Company’s management routinely evaluates the performance of its businesses based upon levels of Adjusted EBITDA, which excludes certain expenses relating to transactions not reflective of our core operations, and because the Company’s loan covenants are based upon levels of Adjusted EBITDA achieved. The Company defines Adjusted EBITDA consistent with its existing revolving credit agreement, as described in the following reconciliation showing the differences between reported GAAP net income and Adjusted EBITDA for the three and nine months ended September 30, 2024 and 2023 (in thousands, except percentages):

Adjusted Free Cash Flow Reconciliation

Clean Harbors reports adjusted free cash flow, which is a non-GAAP financial measure that should not be considered an alternative to net cash from operating activities or other measurements under GAAP. The Company considers adjusted free cash flow 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. 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.
