Clean Harbors Announces First-Quarter 2025 Financial Results

“We began 2025 with a solid, first-quarter performance as our Environmental Services (ES) segment closed Q1 with a strong March helping to overcome unfavorable weather impacts early in the quarter and results in our Safety-Kleen Sustainability Solutions (SKSS) segment exceeded our expectations,” said Mike Battles, Co-Chief Executive Officer. “Demand trends for our disposal and recycling assets were very strong in the quarter. In addition, we posted the best quarterly safety results in our history, registering a Total Recordable Incident Rate (TRIR) of 0.46. Our employees have done a great job continuing to embrace our safety culture and our ‘Safety Starts with Me’ philosophy.”

First-Quarter 2025 Results

Revenues grew 4% to $1.43 billion, compared with $1.38 billion in the same period of 2024. Income from operations was $111.6 million, compared with $125.5 million in the first quarter of 2024 due to higher depreciation and amortization resulting from acquisitions and the new Kimball incinerator.

Net income was $58.7 million, or $1.09 per diluted share, compared with $69.8 million, or $1.29 per diluted share, for the same period in 2024.

Adjusted EBITDA (see description and reconciliation below) was $234.9 million, compared with $230.1 million in the same period of 2024.

Q1 2025 Segment Review

“Despite unfavorable weather early in the quarter that disrupted multiple businesses, our ES segment achieved 4% growth in Adjusted EBITDA and 3% growth in revenue,” said Eric Gerstenberg, Co-Chief Executive Officer. “Top-line growth in the segment was led by our Field Services operations, which increased 32% from the prior-year period, reflecting the HEPACO acquisition. Technical Services revenue grew 5% on strength of volumes and pricing in our network. Incineration utilization, excluding the new Kimball incinerator, was an impressive 88% vs. 79% in the year-ago period. Average incineration price rose more than 5% on a mix-adjusted basis. Safety-Kleen Environmental Services continued its growth trajectory with a 5% revenue increase in the ES segment. The growth in those businesses more than offset a downturn in our Industrial Services business, which declined 10% as some refinery customers continued to delay spending and maintenance compared to the prior-year period.”

“Results in our SKSS segment reflected our efforts to combat the ongoing weak demand and pricing environment in the U.S. base oil and lubricants market by reducing our used oil collection costs. We increased customer charges for collection services, while continuing to gather the volumes needed for our production goals,” said Battles. “Segment revenues increased 9% on greater volumes sold, reflecting our 2024 acquisition of Noble Oil and the shift to higher charge-for-oil (CFO) pricing. These factors, combined with cost-cutting efforts, helped offset a softer commodity price environment year over year, resulting in higher-than-anticipated profitability in SKSS.”

Business Outlook and Financial Guidance

“As we look ahead, we remain optimistic about our overall prospects for 2025,” Gerstenberg said. “While we achieved Q1 results ahead of our initial guidance, we recognize that we are operating in a period of uncertainty regarding U.S. policies on trade and tariffs, and the larger implications for the overall economy. We have taken steps around pricing to offset the additional costs we anticipate from tariffs and have not seen a reduction in demand for our core services. As a result, we are maintaining our Adjusted EBITDA and adjusted free cash flow guidance.”

Battles concluded, “Our confidence in hitting our targets stems from the array of tailwinds we see that should drive our business this year and beyond, including demand for disposal and other services, the ramp-up of our new Kimball incinerator, the expansion of our Field Services business through HEPACO, the emerging PFAS market opportunity and our current pipeline of remediation and waste projects. For SKSS, our focus will remain on actively managing our collection costs and overall expenses, while advancing initiatives like our Castrol partnership and Group III production.”

In the second quarter of 2025, Clean Harbors expects Adjusted EBITDA to grow 1-3% compared with the prior year, with 3-5% growth in the ES segment and lower expense in the Corporate segment more than offsetting an expected year-over-year decline in SKSS. For full-year 2025, Clean Harbors is reiterating its prior guidance and continues to expect:

• Adjusted EBITDA in the range of $1.15 billion to $1.21 billion, or a midpoint of $1.18 billion, which represents 6% growth year over year. This Adjusted EBITDA range is based on anticipated GAAP net income in the range of $377 million to $428 million.
• Adjusted free cash flow in the range of $430 million to $490 million, or a midpoint of $460 million, which represents a nearly 30% increase from prior year. This range is based on anticipated net cash from operating activities in the range of $775 million to $865 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. The Company defines Adjusted EBITDA as described in the following reconciliation showing the differences between reported GAAP net income and Adjusted EBITDA (in thousands, except percentages):

Adjusted Free Cash Flow Reconciliation

Clean Harbors reports adjusted free cash flow, a non-GAAP measure, 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 less additions to property, plant and equipment plus proceeds from sale and disposal of fixed assets. When necessary, the Company adjusts for the cash impact 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.
