Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste, material and personnel costs as well as transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred as a basis for measuring the satisfaction of the performance obligation. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition, or when the waste is shipped to a third-party for processing and disposal. The Company periodically enters into bundled arrangements for the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e., the estimated price that a customer would pay for the services on a standalone basis). Revenues and the related costs from waste that is not yet completely processed and disposed of are deferred. The deferred revenues and costs are recognized when the services are completed.

Environmental Services results are also impacted by the demand for planned and unplanned industrial related cleaning and maintenance services at customer sites, environmental cleanup services on a scheduled or emergency basis, including response to large scale events such as major chemical spills, natural disasters, or other instances where immediate and specialized services are required. The Environmental Services segment results include the Safety-Kleen branches&#8217; core environmental service offerings of containerized waste disposal, parts washer and vacuum services.

The results and integration of the acquired operations of HEPACO, which we acquired in March 2024, also impact the overall segment results as we integrated this business into our Field Services operations. In managing the business and evaluating performance, management tracks the volumes and mix of waste handled and disposed of or recycled, generally through our incinerators, TSDFs and landfills, the utilization rates of our incinerators, equipment and workforce, including billable hours and the number of parts washer services performed, and pricing realized by our business and peer companies as well as other key metrics. Levels of activity and ultimate performance associated with this segment can be impacted by several factors including overall North American GDP, U.S. industrial production, economic conditions in the general manufacturing, chemical and automotive markets, including efforts and economic incentives to increase domestic operations, available capacity at waste disposal outlets, demand for industrial cleaning and related industrial services, weather conditions, efficiency of our operations, technology, changing regulations, competition, market pricing of our services, costs incurred to deliver our services and the management of our related operating costs. </span></div><div style="margin-bottom:8pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:14.5pt">Safety-Kleen Sustainability Solutions - </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Safety-Kleen Sustainability Solutions (&#8220;SKSS&#8221;) segment results are impacted by our customers&#8217; demand for high-quality, environmentally responsible recycled oil products and their demand for our related service and product offerings. SKSS offers high-quality recycled base and blended oil products and other automotive and industrial lubricants to end users including fleet customers, distributors, manufacturers of oil products and industrial plants. Segment results are impacted by market pricing, overall demand and the mix of our oil products sales. Segment results are also predicated on the demand for other SKSS product and service offerings including collection services for used oil, used oil filters and other automotive fluids. The used oil collected is used as feedstock in our oil re-refining to produce our base and blended oil products and other hydraulic oils, lubricants and recycled fuel oil or are integrated into our recycling and disposal network. The results and integration of the acquired operations of Noble also impact the overall segment results. In operating the business and evaluating performance, management tracks the volumes and relative percentages of base and blended oil sales along with various pricing metrics associated with the commodity driven margin between product pricing and the overall revenue generation and costs associated with the collection of used oil. Levels of activity and ultimate performance associated with this segment can be impacted by economic conditions in the manufacturing and automotive services markets, efficiency of our operations, technology, weather conditions, changing regulations, competition and the management of our related operating costs. Overall product pricing as well as revenues generated and/or costs incurred in connection with the collection of used oil and other raw materials associated with the segment&#8217;s oil related products can also be volatile and can be impacted by global events and their relative impact on commodity products and pricing. The overall market price of oil and regulations that change the possible usage of used oil or burning of used oil as a fuel, impact the premium the segment can charge for used oil collections. </span></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Highlights</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Total direct revenues for the three months ended March&#160;31, 2025 were $1,432.0 million, compared with $1,376.7 million for the three months ended March&#160;31, 2024. Our Environmental Services segment direct revenues increased $36.6 million or 3.1% for the three months ended March&#160;31, 2025 from the comparable period in 2024 driven by growth in Field and Emergency Response Services, specifically incremental contributions from the acquisition of HEPACO, as well as growth in our Technical Services and Safety-Kleen core service offerings, offset by contraction of Industrial Services revenues.

for the three months ended March&#160;31, 2025 increased $36.6 million from the comparable period in 2024 driven by incremental revenues from acquisitive growth and contributions from our legacy operations. Field and emergency response service revenues for the three months ended March&#160;31, 2025 increased $52.2 million from the comparable period in 2024 driven by incremental revenue of approximately $50 million from the acquisition of HEPACO as well as overall growth in legacy field and emergency response service offerings. Technical services revenue increased $18.7 million largely due to higher incineration volumes coupled with improved pricing. On a comparative basis and excluding the impacts of the new incinerator in Kimball, Nebraska, which is not expected to be running at full utilization until 2026, utilization at our incinerators was 88% in the first three months of 2025 as compared to 79% in the same period in 2024. Including the new Kimball incinerator, utilization at our incinerators was 81% during the three months ended March&#160;31, 2025. Revenues for Safety-Kleen core service offerings for the three months ended March&#160;31, 2025 grew by $11.9 million from the comparable period in 2024 due to improved pricing for our containerized waste, vacuum and parts washer services despite fewer parts washer services compared to the same period in 2024. Revenue from our industrial services operations declined $37.0 million due to lower turnaround activity and related high-value services for the three months ended March&#160;31, 2025 compared to the same period in 2024. Direct revenues for Canadian operations of the Environmental Services segment decreased by $6.5 million due to foreign currency translation.</span></div><div style="text-indent:36pt"><span

2025, SKSS direct revenues increased $18.7 million compared to the same period in 2024. This growth was mainly due to a $20.0 million increase in revenues from vacuum gas oil and specialty refinery products, driven by the acquisition of Noble, and a $5.9 million increase in revenues from the collection of used oil, attributed to higher pricing for these collection services and increased volumes collected. These increases were partially offset by a $5.9 million decline in base oil sales driven by lower pricing despite increased volumes sold and a $3.7 million decline in blended oil sales which was driven by lower volumes sold and, to a lesser extent, lower pricing. Direct revenues for Canadian operations of the SKSS segment decreased by $1.7 million due to foreign currency translation.</span></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Cost of Revenues</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We believe that management of operating costs is vital to our ability to remain price competitive. We continue to experience inflationary pressures across several cost categories, but most notably related to internal and external labor, transportation, maintenance and energy related costs. We are also subject to uncertainties and cost increases due to the changing regulatory landscape including trade restrictions and tariffs. We aim to manage these increases through constant cost monitoring and a focus on cost savings areas, including lowering employee turnover, as well as our overall customer pricing strategies designed to offset the inflationary impacts on our margins.</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We continue to upgrade the quality and efficiency of our services through the development of new technology and continued modifications and expansion at our facilities while also leveraging certain fixed costs of our operating infrastructure.

Adjusted EBITDA should not be considered an alternative to net income or other measurements under generally accepted accounting principles (&#8220;GAAP&#8221;). As reflected in the reconciliation below, we define Adjusted EBITDA as net income plus accretion of environmental liabilities, stock-based compensation, depreciation and amortization, net other expense, net interest expense and provision for income taxes. Adjusted EBITDA is not calculated identically by all companies, and therefore our measurements of Adjusted EBITDA, while defined consistently and in accordance with our existing credit agreement, may not be comparable to similarly titled measures reported by other companies.</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We use Adjusted EBITDA to enhance our understanding of our operating performance, which represents our views concerning our performance in the ordinary, ongoing and customary course of our operations.

We regularly communicate Adjusted EBITDA results to our lenders since our loan covenants are based upon levels of Adjusted EBITDA achieved and to our board of directors and we discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in determining cash and equity bonus compensation for executives and other employees, largely because we believe that this measure is indicative of how the fundamental business is performing and being managed.</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We also provide information relating to our Adjusted EBITDA so that analysts, investors and other interested persons have the same data that we use to assess our core operating performance.

During the three months ended March&#160;31, 2025, the environmental liability balance decreased due to changes in environmental liability estimates of $9.8 million and expenditures of $2.6 million. These decreases were partially offset by accretion of $3.6 million and new environmental liabilities, including those recognized as a result of recent acquisitions, of $1.2 million. The change in environmental liability estimates was primarily driven by a $10 million decrease in the remedial liability for a site based on our conclusion that loss was no longer probable based on recent evaluation of available evidence.</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We anticipate our environmental liabilities, substantially all of which we assumed in connection with our acquisitions, will be payable over many years and that cash flow from operations will generally be sufficient to fund the payment of such liabilities when required.</span></div><div style="margin-bottom:8pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Events not anticipated (such as future changes in environmental laws and regulations) could require that payments to satisfy our environmental liabilities be made earlier or in greater amounts than currently anticipated, which could adversely affect our results of operations, cash flow and financial condition.

most recently authorized by the board of directors on December 5, 2024, to repurchase up to $1.1 billion of the Company&#8217;s common stock. The stock repurchase plan will expire when all of the available allotted funds under the stock repurchase plan are depleted. As of March&#160;31, 2025, the amount available for repurchase under the board-approved plan is $444.1 million. We have funded and intend to fund the repurchases through available cash resources. The stock repurchase program authorizes us to purchase our common stock on the open market or in privately negotiated transactions periodically in a manner that complies with applicable U.S. securities laws. The number of shares purchased and the timing of the purchases has depended and will depend on several factors, including share price, cash required for business plans, trading volume and other conditions. As part of our share repurchase program, we maintain a repurchase plan in accordance with Rule 10b5-1 promulgated under the Exchange Act. During the three months ended March&#160;31, 2025, 70,309 shares were repurchased under the Rule 10b5-1 plan. Future repurchases may be made as open market or privately negotiated transactions as described above. We have no obligation to repurchase stock under this program and may suspend or terminate the repurchase program at any time.</span></div><div id="i3d54f9c492be4e74978f077be3795073_124"></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">ITEM&#160;3.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:3pt;font-weight:700;line-height:120%">&#160;&#160;&#160;&#160;&#160;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">DEFAULTS UPON SENIOR SECURITIES</span></div><div style="margin-bottom:10pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">None</span></div><div id="i3d54f9c492be4e74978f077be3795073_127"></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">ITEM&#160;4.&#160;&#160;&#160;&#160;MINE SAFETY DISCLOSURES</span></div><div style="margin-bottom:10pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Not applicable</span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">31</span></div></div></div><div id="i3d54f9c492be4e74978f077be3795073_130"></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i3d54f9c492be4e74978f077be3795073_7">Table of Contents</a></span></div></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">ITEM&#160;5.&#160;&#160;&#160;&#160;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">OTHER INFORMATION</span></div><div style="margin-bottom:10pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During the quarter ended March&#160;31, 2025, no director or &#8220;officer&#8221;

REVENUES
The Company generates revenues through the following operating segments: Environmental Services and Safety-Kleen Sustainability Solutions ("SKSS"). The Company's Environmental Services operating segment generally has
four
sources of revenue and the SKSS operating segment has
two
sources of revenue. The Company disaggregates third-party revenues by geographic location and source of revenue as management believes these categories depict how revenue and cash flows are affected by economic factors. The tables below present revenue billed to outside customers by a particular segment. Should it be necessary, there will be intercompany transactions to present the direct revenues in the appropriate segment results. The Company's significant sources of revenue include:
Technical Services
—Technical Services contribute to the revenues of the Environmental Services operating segment. Revenues for these services are generated from fees charged for waste material management and disposal services including onsite environmental management services, collection and transportation, packaging, recycling, treatment and disposal of waste and remediation projects. These services handle hazardous and/or non-hazardous waste, including per- and polyfluoroalkyl substances ("PFAS"). Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are
6
Table of Contents
long-term in nature and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste, material and personnel costs as well as transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred as a basis for measuring the satisfaction of the performance obligation. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition, or when the waste is shipped to a third-party for processing and disposal. The Company periodically enters into bundled arrangements for the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e., the estimated price that a customer would pay for the services on a standalone basis). Revenues and the related costs from waste that is not yet completely processed and disposed of are deferred. The deferred revenues and costs are recognized when the services are completed. The period between collection and transportation and the final processing and disposal ranges depending on the location of the customer, but generally is measured in days.
Industrial Services
—Industrial Services contribute to the revenues of the Environmental Services operating segment. These revenues are primarily generated from industrial and specialty services provided to refineries, chemical plants, manufacturing facilities, power generation companies and other industrial customers throughout North America. Services include in-plant cleaning and maintenance services, plant outage and turnaround services, specialty cleaning services including chemical cleaning, pigging and high and ultra-high pressure water cleaning, leak detection and repair, daylighting, production services and upstream energy services. Services are provided based on purchase orders or agreements with the customer and include prices based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred.
Field and Emergency Response Services
—Field and Emergency Response Services, which includes contributions from Hepaco Blocker, Inc. and its subsidiaries (collectively, "HEPACO") since its acquisition on March 22, 2024, contribute to the revenues of the Environmental Services operating segment. Field Services revenues are generated from cleanup services at customer sites, including those managed by municipalities and utility providers, or other locations on a scheduled or emergency response basis. Services include confined space entry for tank cleaning, site decontamination, environmental remediation, railcar cleaning, manhole/vault clean outs, product recovery and transfer and vacuum services. Additional services include filtration, water treatment services and wetland restoration. Response services for environmental emergencies of any scale range from man-made disasters such as oil spills to natural disasters like hurricanes. Emergency response services also include spill cleanup on land and water, as well as contagion disinfection, decontamination and disposal services. Field and emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. The duration of such services can be over a number of hours, several days or even months for larger scale projects.
Safety-Kleen Environmental Services
—Safety-Kleen Environmental Services revenues contribute both to the Environmental Services operating segment and the SKSS operating segment. Revenues from providing containerized waste handling and disposal services, parts washer services and vacuum services, referred to collectively as the Safety-Kleen branches' core service offerings, contribute to the revenues of the Environmental Services operating segment. In addition, sales of packaged blended oil products and other complementary product sales contribute to the revenues of the Environmental Services operating segment. Revenues generated from waste oil, anti-freeze and oil filter collection services, sales of bulk blended oil products and sales of bulk automotive fluids contribute to the SKSS operating segment. Due to the complementary nature of these products and services and their customer base, there are some cross-overs of Safety-Kleen Environmental Services revenue streams between the Environmental Services and SKSS operating segments.
Generally, the revenue from services is recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The duration of such services can be over a number of hours or several days. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Product revenue is recognized upon the transfer of control whereby control transfers when the products are delivered to the customer. Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of waste. Related collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. Parts washer services include customer use of the Company's parts washer equipment, cleaning and maintenance of the parts washer equipment and removal and replacement of used cleaning fluids. Parts washer services are
7
Table of Contents
considered a single performance obligation due to the highly integrated and interdependent nature of the arrangement. Revenue from parts washer services is recognized over the service interval as the customer receives the benefit of the services.
Safety-Kleen Oil
—Safety-Kleen Oil related sales contribute to the revenues of the SKSS segment. These revenues are generated from bulk sales of high-quality base and blended lubricating oils to many industries, including major oil brands, lubricant blenders and manufacturers, blended lubricant distributors and government agencies. The business also sells recycled fuel oil to asphalt plants, industrial plants and pulp and paper companies. The used oil is also processed into vacuum gas oil which can be further re-refined into lubricant base oils or sold directly into the marine diesel oil fuel market. By-products coming off the refinery are a mixture of light end distillates and asphalt flux that are sold into various markets. Revenue for oil products is recognized at a point in time, upon the transfer of control. Generally, control transfers when the products are delivered to the customer.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets) and customer advances and deposits or deferred revenue (contract liabilities) on the consolidated balance sheet.

Table of Contents
Generally, billing occurs subsequent to revenue recognition, as a right to payment is not just subject to passage of time, resulting in contract assets, which are generally classified as current. The Company sometimes receives advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. These assets and liabilities are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. The contract liability balances at the beginning of each period presented are generally fully recognized in the subsequent
three-month
period.

68.7
million, net of cash acquired. The acquisition of Noble expands the SKSS segment's oil collection operations in the southeastern region of the United States while also adding incremental production from the re-refinery owned and operated by the acquired company.

Financing Activities
The Company's significant financing arrangements are described in Note 12, "Financing Arrangements," in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 and there have been no material changes to the arrangements described therein. As of March 31, 2025 and December 31, 2024, the estimated fair value of the Company's outstanding long-term debt, including the current portion, was $
2.8
billion. The Company's estimates of fair value of its long-term debt, including the current portion, are based on quoted market prices or other available market data which are considered Level 2 measures according to the fair value hierarchy. Level 2 utilizes quoted market prices in markets that are not active, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency for similar assets and liabilities.
The Company maintains a $
600.0
million revolving credit facility under which the Company had
no
outstanding loan balance as of March 31, 2025 or December 31, 2024 . As of March 31, 2025, the Company had $
462.4
million available to borrow under the revolving credit facility and outstanding letters of credit were $
137.6
million.
Cash Flow Hedges
The Company's strategy to hedge against fluctuations in variable interest rates involves entering into interest rate derivative agreements.
13
Table of Contents
Although the interest rate on the Company's senior secured term loans is variable, the Company has effectively fixed the interest rate on $
600.0
million aggregate principal amount of the term loans outstanding by entering into interest rate swap agreements in 2022 with a notional amount of $
600.0
million ("2022 Swaps"). Under the terms of the 2022 Swaps, the Company receives interest based on the one-month SOFR index and pays interest at a weighted annual interest rate of
1.965
%, resulting in an effective interest rate of
3.71
% when considering the
1.75
% interest rate margin of the term loans. For the three months ended March 31, 2025, including the
1.75
% interest rate margin, the effective annual interest rate of this $
600.0
million of principal debt was approximately
3.71
%. The 2022 Swaps will expire on September 30, 2027.
The Company recognizes the derivative instruments as either assets or liabilities on the balance sheet at fair value. As of March 31, 2025 and December 31, 2024, the Company has recorded a derivative asset with a fair value of $
24.6
million and $
32.4
million, respectively, within Other long-term assets on the consolidated balance sheets in connection with the 2022 Swaps.
No ineffectiveness has been identified on the 2022 Swaps and, therefore, the change in fair value is recorded in stockholders' equity as a component of accumulated other comprehensive loss. Amounts are reclassified from accumulated other comprehensive loss into interest expense on the unaudited consolidated statement of operations in the same period or periods during which the hedged transactions affect earnings.
(12)
EARNINGS PER SHARE
The computation of basic earnings per share (EPS) is based on the weighted-average number of common shares outstanding. The computation of diluted EPS is based on the weighted-average number of common shares outstanding and potential dilutive common shares during the period as determined by using the treasury stock method.
The following are computations of basic and diluted earnings per share (in thousands, except per share amounts):

Employee Stock Purchase Plan
The Clean Harbors Employee Stock Purchase Plan (the "ESPP") provides a means for eligible employees of the Company to authorize after-tax payroll deductions on a voluntary basis to be used for the periodic purchase of the Company's common stock at a
10
% discount to its fair market value. The purchase price paid by the employees will be
90
% of the lower of the closing price of the Company's common stock on (i) the first trading day of the offering period or (ii) the last trading day of the offering period. The contribution periods run from January to June and July to December with share issuances under the ESPP occurring on the closest business day on or prior to June 30 and December 31.
No
shares were issued under the plan during the three months ended March 31, 2025.

COMMITMENTS AND CONTINGENCIES
The Company and its subsidiaries are subject to legal proceedings and claims arising in the ordinary course of business. Actions filed against the Company arise from commercial and employment-related claims including alleged class actions related to sales practices and wage and hour claims. The plaintiffs in these actions may be seeking damages or injunctive relief or both. These actions are in various jurisdictions and stages of proceedings, and some are covered in part by insurance. In addition, the Company's waste management services operations are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of government authorities and other interested parties. The issues involved in such proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties ("third-party sites") to which either the Company or the prior owners of certain of the Company's facilities shipped waste.
At March 31, 2025 and December 31, 2024, the Company had recorded reserves of $
16.9
million and $
29.8
million, respectively, for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. As of March 31, 2025 and December 31, 2024, the $
16.9
million and $
29.8
million, respectively, of reserves consisted of (i) $
9.6
million and $
23.3
million, respectively, related to pending legal or administrative proceedings, including Superfund liabilities, which were included in remedial liabilities on the consolidated balance sheets, and (ii) $
7.3
million and $
6.5
million, respectively, primarily related to federal, state and provincial enforcement actions, which were included in accrued expenses on the consolidated balance sheets.
In management's opinion, it is not reasonably possible that the potential liability beyond what has been recorded, if any, that may result from these actions, either individually or collectively, will have a material effect on the Company's financial position, results of operations or cash flows. The Company periodically adjusts the aggregate amount of these reserves when actual or probable liabilities are paid or otherwise discharged, new claims arise, or additional relevant information about existing or probable claims becomes available.

Legal or Administrative Proceedings
As of March 31, 2025, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during 2025, relate to Safety-Kleen product liability cases and Superfund proceedings.
Safety-Kleen Product Liability Cases:
Safety-Kleen, Inc. ("Safety-Kleen"), which is a legal entity acquired by the Company in 2012, has been named as a defendant in certain product liability cases that are currently pending in various courts and jurisdictions throughout the United States. As of March 31, 2025, there were approximately
71
proceedings (excluding cases which have been settled but not formally dismissed) wherein persons claim personal injury resulting from the use of Safety-Kleen's parts cleaning equipment or cleaning products. These proceedings typically involve allegations that the solvent used in Safety-Kleen's parts cleaning equipment contains contaminants and/or that Safety-Kleen's recycling process does not effectively remove the contaminants that become entrained in the solvent during their use. In addition, certain claimants assert that Safety-Kleen failed to warn adequately the product user of potential risks, including a historic failure to warn that solvent contains trace amounts of toxic or hazardous substances such as benzene.
The Company maintains insurance that it believes will provide coverage for these product liability claims (over amounts accrued for self-insured retentions and deductibles in certain limited cases), except for punitive damages to the extent not insurable under state law or excluded from insurance coverage. The Company historically has vigorously defended, and intends to continue to vigorously defend, itself and the safety of its products against all of these claims. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. Consequently, the Company is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of March 31, 2025. From January 1, 2025 to March 31, 2025,
two
product liability claims were settled or dismissed. Due to the nature of these claims and the related insurance, the Company did not incur any expense as insurance provided coverage in full for all such claims. Safety-Kleen may be named in similar, additional lawsuits in the future, including claims for which insurance coverage may not be available.
Superfund Proceedings:
The Company has been notified that either the Company or the prior owners of certain facilities the Company has since acquired have been identified as potentially responsible parties ("PRPs") or potential PRPs of indemnification obligations in connection with
132
sites which are subject to or are proposed to become subject to proceedings under federal or state Superfund laws. Of the
132
Superfund related sites,
six
involve facilities that are now owned or leased by the Company and
126
involve third-party sites which received waste potentially shipped by the Company or the prior owners of certain facilities the Company has since acquired. Of the
126
third-party sites,
30
are now settled,
12
are currently requiring expenditures on remediation and
84
are not currently requiring expenditures on remediation.
In connection with each site, the Company has estimated the extent, if any, to which it may be subject, either directly or as a result of any indemnification obligations, for cleanup and remediation costs, related legal and consulting costs associated with PRP investigations, settlements and related legal and administrative proceedings. The amount of such actual and potential liability is inherently difficult to estimate because of, among other relevant factors, uncertainties as to the legal liability (if any) of the Company or the prior owners of certain of the Company's facilities to contribute a portion of the cleanup costs, the assumptions that must be made in calculating the estimated cost and timing of remediation, the identification of other PRPs and their respective capability and obligation to contribute to remediation efforts and the existence and legal standing of indemnification agreements (if any) with prior owners, which may either benefit the Company or subject the Company to potential indemnification obligations. The Company believes its potential monetary liability could exceed $1.0 million at
three
of the
132
Superfund related sites.
Of the
126
third-party sites at which the Company has been notified it is a PRP or potential PRP or may have indemnification obligations, the Company has indemnification agreements at a total of
17
sites. These agreements indemnify the Company with respect to any liability at the
17
sites for waste disposed prior to the Company's acquisition of the former subsidiaries of Waste Management, Inc. and McKesson Corporation which had shipped waste to those sites. Accordingly, the indemnifying parties are paying all costs of defending those subsidiaries in those
17
cases, including legal fees and settlement costs. However, there can be no guarantee that the Company's ultimate liabilities for those sites will not exceed the amount recorded or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs. Except for those indemnification agreements discussed, the Company does not have an indemnity agreement with respect to any of the
126
third-party sites discussed above.
Federal, State and Provincial Enforcement Actions
From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of March 31, 2025 and December 31, 2024, there were
two
proceedings for which the Company believed it was possible that the sanctions could equal or exceed $1.0 million. As of the date of these financial statements, the Company believes that the fines or other penalties in this or any of the other regulatory proceedings will, individually or in the aggregate, not have a material effect on its financial condition, results of operations or cash flows.

SEGMENT REPORTING
Segment reporting is prepared on the same basis that the Company's chief operating decision maker ("CODM"), which is a committee comprised of the Company's Co-Chief Executive Officers, manages the business, makes operating decisions and assesses performance. The Company is managed and reports as
two
operating segments; (i) the Environmental Services segment and (ii) the Safety-Kleen Sustainability Solutions segment.
Third-party revenue is revenue billed to outside customers by a particular segment. Direct revenue is revenue allocated to the segment providing the product or service. Intersegment revenues represent the sharing of third-party revenues among the segments based on products and services provided by each segment as if the products and services were sold directly to the third-party. The intersegment revenues are shown net. The operations not managed through the Company's operating segments described above are recorded as "Corporate." Although such transactions are excluded from the business segment results, they are included in reported consolidated earnings.
The following tables reconcile third-party revenues to direct revenues by Reportable Segment (in thousands):

The primary financial measure by which the CODM evaluates the performance of its segments is Adjusted EBITDA, which consists of net income plus accretion of environmental liabilities, stock-based compensation, depreciation and amortization, net interest expense, loss on early extinguishment of debt and provision for income taxes and excludes other transactions not deemed representative of fundamental segment results and other expense, net. Transactions between the segments are accounted for at the Company's best estimate based on similar transactions with outside customers.
The CODM uses Adjusted EBITDA to enhance their understanding of segment operating performance, which represents the Company's performance in the ordinary, ongoing and customary course of operations. The reportable segment operating performance Adjusted EBITDA is used by the CODM to make key operating decisions such as the allocation of resources. Total assets by segment are not used by the CODM to assess the performance of, or allocate resources to, the Company's segments. Therefore total assets by segment are not disclosed.

Overview
We are North America's leading provider of environmental and industrial services, supporting our customers in finding environmentally responsible solutions to further their sustainability goals. Everywhere industry meets the environment, we strive to provide eco-friendly services and products that protect and restore North America's natural environment. We believe we operate, in the aggregate, the largest number of hazardous waste incinerators, landfills and treatment, storage and disposal facilities ("TSDFs") in North America. We serve over 350,000 customers, including the majority of Fortune 500 companies, across various markets including chemical and manufacturing, as well as numerous government agencies. These customers rely on us to safely deliver a broad range of services, including, but not limited to end-to-end hazardous waste management, emergency response, industrial cleaning and maintenance and recycling services. We are also a leading provider of parts cleaning and related environmental services to general manufacturing, automotive and commercial customers in North America and the largest re-refiner and recycler of used oil in North America.
Performance of our segments is evaluated on several factors of which the primary financial measure is Adjusted EBITDA, a non-GAAP measure which is reconciled to our GAAP net income and described more fully below. The following is a discussion of how management evaluates its segments in regards to other factors, including key performance indicators that management uses to assess the segments' results, as well as certain macroeconomic trends and influences that impact each reportable segment:
•
Environmental Services -
The Environmental Services segment results are driven by the customer demand for our wide variety of services, the volume of waste managed and project work requiring responsible waste handling and disposal. Environmental Services results are also impacted by the demand for planned and unplanned industrial related cleaning and maintenance services at customer sites, environmental cleanup services on a scheduled or emergency basis, including response to large scale events such as major chemical spills, natural disasters, or other instances where immediate and specialized services are required. The Environmental Services segment results include the Safety-Kleen branches' core environmental service offerings of containerized waste disposal, parts washer and vacuum services. These results are driven by the volumes of waste collected from these customers, the overall number of parts washers
20
Table of Contents
placed at customer sites, and the demand for and frequency of other offered services. The results and integration of the acquired operations of HEPACO, which we acquired in March 2024, also impact the overall segment results as we integrated this business into our Field Services operations. In managing the business and evaluating performance, management tracks the volumes and mix of waste handled and disposed of or recycled, generally through our incinerators, TSDFs and landfills, the utilization rates of our incinerators, equipment and workforce, including billable hours and the number of parts washer services performed, and pricing realized by our business and peer companies as well as other key metrics. Levels of activity and ultimate performance associated with this segment can be impacted by several factors including overall North American GDP, U.S. industrial production, economic conditions in the general manufacturing, chemical and automotive markets, including efforts and economic incentives to increase domestic operations, available capacity at waste disposal outlets, demand for industrial cleaning and related industrial services, weather conditions, efficiency of our operations, technology, changing regulations, competition, market pricing of our services, costs incurred to deliver our services and the management of our related operating costs.
•
Safety-Kleen Sustainability Solutions -
Safety-Kleen Sustainability Solutions ("SKSS") segment results are impacted by our customers' demand for high-quality, environmentally responsible recycled oil products and their demand for our related service and product offerings. SKSS offers high-quality recycled base and blended oil products and other automotive and industrial lubricants to end users including fleet customers, distributors, manufacturers of oil products and industrial plants. Segment results are impacted by market pricing, overall demand and the mix of our oil products sales. Segment results are also predicated on the demand for other SKSS product and service offerings including collection services for used oil, used oil filters and other automotive fluids. The used oil collected is used as feedstock in our oil re-refining to produce our base and blended oil products and other hydraulic oils, lubricants and recycled fuel oil or are integrated into our recycling and disposal network. The results and integration of the acquired operations of Noble also impact the overall segment results. In operating the business and evaluating performance, management tracks the volumes and relative percentages of base and blended oil sales along with various pricing metrics associated with the commodity driven margin between product pricing and the overall revenue generation and costs associated with the collection of used oil. Levels of activity and ultimate performance associated with this segment can be impacted by economic conditions in the manufacturing and automotive services markets, efficiency of our operations, technology, weather conditions, changing regulations, competition and the management of our related operating costs. Overall product pricing as well as revenues generated and/or costs incurred in connection with the collection of used oil and other raw materials associated with the segment's oil related products can also be volatile and can be impacted by global events and their relative impact on commodity products and pricing. The overall market price of oil and regulations that change the possible usage of used oil or burning of used oil as a fuel, impact the premium the segment can charge for used oil collections.
Highlights
Total direct revenues for the three months ended March 31, 2025 were $1,432.0 million, compared with $1,376.7 million for the three months ended March 31, 2024. Our Environmental Services segment direct revenues increased $36.6 million or 3.1% for the three months ended March 31, 2025 from the comparable period in 2024 driven by growth in Field and Emergency Response Services, specifically incremental contributions from the acquisition of HEPACO, as well as growth in our Technical Services and Safety-Kleen core service offerings, offset by contraction of Industrial Services revenues. For the three months ended March 31, 2025, our SKSS segment direct revenues increased $18.7 million or 9.1% from the comparable period in 2024, driven by the contributions of Noble as well as growth in charge for oil revenue, which was partially offset by lower sales of blended and base oil. Foreign currency translation of our Canadian operations negatively impacted our consolidated direct revenues by $8.2 million in the three months ended March 31, 2025 compared to the same period in 2024.
Income from operations for the three months ended March 31, 2025 was $111.6 million, compared with $125.5 million in the three months ended March 31, 2024, representing a decrease of 11.0%, primarily driven by an increase in depreciation and amortization expense as a result of the incremental assets from the acquisitions of HEPACO and Noble, which occurred in the first quarter of 2024. Net income for the three months ended March 31, 2025 was $58.7 million, a decrease of $11.2 million, or 16.0% as compared with net income of $69.8 million in the three months ended March 31, 2024.
Adjusted EBITDA, which is the primary financial measure by which we evaluate the operating performance of our segments, increased $4.8 million or 2.1%, from $230.1 million in the three months ended March 31, 2024 to $234.9 million in the three months ended March 31, 2025. Additional information regarding Adjusted EBITDA, which is a non-GAAP measure, including a reconciliation of net income to Adjusted EBITDA, appears below under
"Adjusted EBITDA."
Net cash from operating activities for the three months ended March 31, 2025 decreased $16.9 million from $18.5 million in 2024 to $1.6 million in 2025 due to increased working capital balances as well as higher interest payments. As is typical for the first
21
Table of Contents
quarter, adjusted free cash flow, which management uses to measure our financial strength and ability to generate cash, was an outflow of $115.7 million in the three months ended March 31, 2025 as compared to an outflow of $118.4 million in the comparable period of 2024. Additional information regarding adjusted free cash flow, which is a non-GAAP measure, including a reconciliation of net cash from operating activities to adjusted free cash flow, appears below under

Environmental Services direct revenues for the three months ended March 31, 2025 increased $36.6 million from the comparable period in 2024 driven by incremental revenues from acquisitive growth and contributions from our legacy operations. Field and emergency response service revenues for the three months ended March 31, 2025 increased $52.2 million from the comparable period in 2024 driven by incremental revenue of approximately $50 million from the acquisition of HEPACO as well as overall growth in legacy field and emergency response service offerings. Technical services revenue increased $18.7 million largely due to higher incineration volumes coupled with improved pricing. On a comparative basis and excluding the impacts of the new incinerator in Kimball, Nebraska, which is not expected to be running at full utilization until 2026, utilization at our incinerators was 88% in the first three months of 2025 as compared to 79% in the same period in 2024. Including the new Kimball incinerator, utilization at our incinerators was 81% during the three months ended March 31, 2025. Revenues for Safety-Kleen core service offerings for the three months ended March 31, 2025 grew by $11.9 million from the comparable period in 2024 due to improved pricing for our containerized waste, vacuum and parts washer services despite fewer parts washer services compared to the same period in 2024. Revenue from our industrial services operations declined $37.0 million due to lower turnaround activity and related high-value services for the three months ended March 31, 2025 compared to the same period in 2024. Direct revenues for Canadian operations of the Environmental Services segment decreased by $6.5 million due to foreign currency translation.

In the three months ended March 31, 2025, SKSS direct revenues increased $18.7 million compared to the same period in 2024. This growth was mainly due to a $20.0 million increase in revenues from vacuum gas oil and specialty refinery products, driven by the acquisition of Noble, and a $5.9 million increase in revenues from the collection of used oil, attributed to higher pricing for these collection services and increased volumes collected. These increases were partially offset by a $5.9 million decline in base oil sales driven by lower pricing despite increased volumes sold and a $3.7 million decline in blended oil sales which was driven by lower volumes sold and, to a lesser extent, lower pricing. Direct revenues for Canadian operations of the SKSS segment decreased by $1.7 million due to foreign currency translation.
Cost of Revenues
We believe that management of operating costs is vital to our ability to remain price competitive. We continue to experience inflationary pressures across several cost categories, but most notably related to internal and external labor, transportation, maintenance and energy related costs. We are also subject to uncertainties and cost increases due to the changing regulatory landscape including trade restrictions and tariffs. We aim to manage these increases through constant cost monitoring and a focus on cost savings areas, including lowering employee turnover, as well as our overall customer pricing strategies designed to offset the inflationary impacts on our margins.
We continue to upgrade the quality and efficiency of our services through the development of new technology and continued modifications and expansion at our facilities while also leveraging certain fixed costs of our operating infrastructure. We invest in

new business opportunities and aggressively implement strategic sourcing and logistics solutions, while also continuing to optimize our management and operating structure in an effort to manage our operating margins.

Environmental Services cost of revenues for the three months ended March 31, 2025 increased $27.0 million from the comparable period in 2024, and remained relatively consistent as percentage of revenues. Commensurate with the revenue growth in the business and recent acquisitions discussed above, labor and benefit related costs increased $25.1 million and equipment and supply costs increased $6.5 million for the three months ended March 31, 2025 when compared to the three months ended March 31, 2024. The remaining increase was spread across various cost categories and was driven by acquisitions. Partially offsetting these cost increases were decreases in third-party labor costs of $7.9 million and external transportation, vehicle and fuel related costs of $2.1 million for the three months ended March 31, 2025 when compared to the three months ended March 31, 2024.

SKSS cost of revenues for the three months ended March 31, 2025 increased $22.6 million from the comparable period in 2024 and increased 3.8% as a percentage of revenues. The cost increase is primarily due to additional expenses from the Noble operations. As a percentage of revenues, these costs increased primarily due to the higher cost per gallon of base oil products sold, the overall mix of product sales and market related pricing decreases discussed in the revenue section during the three months ended March 31, 2025 as compared to the same period in the prior year.
Selling, General and Administrative Expenses
We aim to manage our selling, general and administrative ("SG&A") expenses in line with the overall performance of our segments and corresponding revenue levels. Our goal is to achieve this through enhanced technology, process improvements and strategic expense management. Expanding our support functions globally has led to both profitability and productivity improvements. We believe our ability to properly align these costs with business performance is reflective of our strong management of the businesses and further promotes our ability to remain competitive in the marketplace.
The SG&A balances as set forth below in this section exclude stock-based compensation expense, which is presented in SG&A on the Company's Consolidated Statement of Operations but is not included in the Company's measurement of Adjusted EBITDA. For a discussion of significant changes in consolidated stock-based compensation expense, please refer to the separate section below.

Environmental Services SG&A expenses for the three months ended March 31, 2025 remained relatively consistent with the comparable period in 2024, both in dollar amount and as a percentage of revenues. The current quarter results include the impact of reducing estimated costs to remediate a site by approximately $10 million to reflect our conclusion that a loss was no longer probable based on recent evaluation of available evidence. This benefit was partially offset by higher labor and benefits related costs of $7.9

We manage our Corporate SG&A expenses commensurate with the overall total Company performance and direct revenue levels. As a percentage of total Company direct revenues, these costs remained relatively consistent in the three months ended March 31, 2025 and the comparable period in the prior year, continuing our trend of leveraging our SG&A base in the midst of revenue growth discussed above.
Corporate SG&A expenses for the three months ended March 31, 2025 increased $2.7 million when compared to the same period in the prior year. The increase in Corporate SG&A expenses for the three months ended March 31, 2025 was driven by higher spending on acquisitions and systems investments when compared to the same period in 2024.
Adjusted EBITDA
Management considers Adjusted EBITDA to be a measurement of performance which provides useful information to both management and investors. Adjusted EBITDA should not be considered an alternative to net income or other measurements under generally accepted accounting principles ("GAAP"). As reflected in the reconciliation below, we define Adjusted EBITDA as net income plus accretion of environmental liabilities, stock-based compensation, depreciation and amortization, net other expense, net interest expense and provision for income taxes. Adjusted EBITDA is not calculated identically by all companies, and therefore our measurements of Adjusted EBITDA, while defined consistently and in accordance with our existing credit agreement, may not be comparable to similarly titled measures reported by other companies.
We use Adjusted EBITDA to enhance our understanding of our operating performance, which represents our views concerning our performance in the ordinary, ongoing and customary course of our operations. We historically have found it helpful, and believe that investors have found it helpful, to consider an operating measure that excludes certain expenses relating to transactions not reflective of our core operations.
The information about our operating performance provided by Adjusted EBITDA is used by our management for a variety of purposes. We regularly communicate Adjusted EBITDA results to our lenders since our loan covenants are based upon levels of Adjusted EBITDA achieved and to our board of directors and we discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in determining cash and equity bonus compensation for executives and other employees, largely because we believe that this measure is indicative of how the fundamental business is performing and being managed.
We also provide information relating to our Adjusted EBITDA so that analysts, investors and other interested persons have the same data that we use to assess our core operating performance. We believe that Adjusted EBITDA should be viewed only as a supplement to the GAAP financial information. We also believe, however, that providing this information in addition to, and together with, GAAP financial information provides a better understanding of our core operating performance and how management evaluates and measures our performance.

For the three months ended March 31, 2025, the provision for income taxes decreased $10.0 million as a result of lower pre-tax income compared to the same period in 2024. The reduction in our effective tax rate was driven by the write-off of a deferred tax asset with a full valuation allowance associated with the remedial liability change in estimate discussed above.
Liquidity and Capital Resources
We assess our liquidity in terms of our ability to generate cash to fund our operating, investing, and financing activities. Our primary ongoing cash requirements will be to fund operations, capital expenditures, interest payments and investments in line with our business strategy as of the date of this report. We believe our future operating cash flows will be sufficient to meet our future operating and internal investing cash needs. We monitor our actual needs and forecasted cash flows, our liquidity and our capital resources, enabling us to plan our present needs and fund items that may arise during the year as a result of changing business conditions or opportunities. Furthermore, our existing cash balance and the availability of additional borrowings under our revolving credit facility provide additional potential sources of liquidity should they be required.

Net cash from operating activities
Net cash from operating activities for the three months ended March 31, 2025 was $1.6 million as compared to $18.5 million in the same period of 2024. This $16.9 million decrease in operating cash flows was attributable to an increase in working capital balances for the three months ended March 31, 2025 as compared to the same period in 2024, as well as lower income from operations and higher cash paid for interest.
Net cash used in investing activities
Net cash used in investing activities for the three months ended March 31, 2025 was $120.3 million, a decrease of $489.5 million from the comparable period in 2024. In the three months ended March 31, 2024, we paid $475.3 million for acquisitions, including the purchase of HEPACO and Noble. Additions to property, plant and equipment decreased $19.2 million, primarily due to notable project spend on the Baltimore, Maryland strategic project and the Kimball incinerator in the three months ended March 31, 2024.
Net cash (used in) from financing activities
Net cash used in financing activities for the three months ended March 31, 2025 was $79.3 million, as compared to net cash from financing activities of $486.0 million for the three months ended March 31, 2024. The primary drivers of this change were the incurrence of term loans net of discount and deferred financing costs of $494.7 million in 2024 to fund the acquisitions executed during the period. These amounts were partially offset by higher cash paid for repurchases of stock of $50.0 million, tax payments on withholdings of vested restricted stock of $5.6 million and finance lease payments of $5.4 million during 2025.
Adjusted
Free Cash Flow
Management considers adjusted free cash flow, a non-GAAP measure, to be a measure of liquidity which provides useful information to management, creditors and investors about our financial strength and our ability to generate cash. Additionally, adjusted free cash flow is a metric on which a portion of management incentive compensation is based. We define adjusted free cash flow as net cash from operating activities, less additions to property, plant and equipment plus proceeds from sales or disposals of fixed assets. When necessary, management 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 our measurements of adjusted free cash flow may not be comparable to similarly titled measures reported by other companies.

Summary of Capital Resources
At March 31, 2025, cash and cash equivalents and marketable securities totaled $595.3 million, compared to $789.8 million at December 31, 2024. At March 31, 2025, cash and cash equivalents held by our Canadian subsidiaries totaled $96.9 million. The cash and cash equivalents and marketable securities balance for our U.S. operations was $498.4 million at March 31, 2025. Our U.S. operations had net operating cash inflows of $14.1 million for the three months ended March 31, 2025.
We maintain a $600.0 million revolving credit facility of which, as of March 31, 2025, approximately $462.4 million, was available to borrow under the facility, with letters of credit of $137.6 million outstanding.
Material Capital Requirements
Capital Expenditures
Capital expenditures during the first three months of 2025 were $118.7 million as compared to $137.9 million during the first three months of 2024. The decrease was driven by incremental investments in our Baltimore, Maryland and Kimball incinerator facilities which occurred in 2024. We anticipate that 2025 capital spending, net of disposals, will be in the range of $360.0 million to $390.0 million. This includes a long-term growth investment of approximately $15 million for the Phoenix hub. We expect spending on this project to begin in the second quarter of 2025 with the purchase of the facility.
We anticipate that the capital spending will be funded by cash from our operations. Unanticipated changes in environmental regulations could require us to make significant capital expenditures for our facilities and adversely affect our results of operations and cash flow.
Financing Arrangements
As of March 31, 2025, our financing arrangements include (i) $545.0 million of 4.875% senior unsecured notes due 2027, (ii) $1.5 billion of senior secured term loans due 2028, (iii) $300.0 million of 5.125% senior unsecured notes due 2029 and (iv) $500.0 million of 6.375% senior unsecured notes due 2031. As noted above, we also maintain our $600.0 million revolving credit facility with no amounts owed as of March 31, 2025.
The material terms of these arrangements are discussed further in Note 11, "Financing Arrangements," to the accompanying unaudited consolidated financial statements.
As of March 31, 2025, we were in compliance with the covenants of all of our debt agreements, and we believe we will continue to meet such covenants.
Common Stock Repurchases Pursuant to Publicly Announced Plan
The Company's common stock repurchases are made pursuant to the board-approved plan to repurchase up to $1.1 billion of the Company's common stock. During the three months ended March 31, 2025 and March 31, 2024, the Company repurchased and retired 256,473 and 27,265 shares, respectively, of the Company's common stock for total expenditures of $55.0 million and $5.0 million, respectively.
Through March 31, 2025, the Company has repurchased and retired a total of approximately 9.0 million shares of its common stock for $655.9 million under the board-approved plan, and, as of March 31, 2025, an additional $444.1 million remained available for repurchase of shares.

Total environmental liabilities as of March 31, 2025 were $234.0 million, a decrease of $7.5 million compared to December 31, 2024. During the three months ended March 31, 2025, the environmental liability balance decreased due to changes in environmental liability estimates of $9.8 million and expenditures of $2.6 million. These decreases were partially offset by accretion of $3.6 million and new environmental liabilities, including those recognized as a result of recent acquisitions, of $1.2 million. The change in environmental liability estimates was primarily driven by a $10 million decrease in the remedial liability for a site based on our conclusion that loss was no longer probable based on recent evaluation of available evidence.
We anticipate our environmental liabilities, substantially all of which we assumed in connection with our acquisitions, will be payable over many years and that cash flow from operations will generally be sufficient to fund the payment of such liabilities when required.
Events not anticipated (such as future changes in environmental laws and regulations) could require that payments to satisfy our environmental liabilities be made earlier or in greater amounts than currently anticipated, which could adversely affect our results of operations, cash flow and financial condition. Conversely, the development of new treatment technologies or other circumstances may arise in the future which may reduce amounts ultimately paid.
Letters of Credit
We obtain standby letters of credit as security for financial assurances we have been required to provide to regulatory bodies for our hazardous waste facilities and which would be called only in the event that we fail to satisfy closure, post-closure and other obligations under the permits issued by those regulatory bodies for such licensed facilities. As of March 31, 2025, there were $137.6 million outstanding letters of credit. See Note 11, "Financing Arrangements," to the accompanying unaudited consolidated financial statements.

(3)    The Company's common stock repurchases are made pursuant to the stock repurchase plan, which was most recently authorized by the board of directors on December 5, 2024, to repurchase up to $1.1 billion of the Company's common stock. The stock repurchase plan will expire when all of the available allotted funds under the stock repurchase plan are depleted. As of March 31, 2025, the amount available for repurchase under the board-approved plan is $444.1 million. We have funded and intend to fund the repurchases through available cash resources. The stock repurchase program authorizes us to purchase our common stock on the open market or in privately negotiated transactions periodically in a manner that complies with applicable U.S. securities laws. The number of shares purchased and the timing of the purchases has depended and will depend on several factors, including share price, cash required for business plans, trading volume and other conditions. As part of our share repurchase program, we maintain a repurchase plan in accordance with Rule 10b5-1 promulgated under the Exchange Act. During the three months ended March 31, 2025, 70,309 shares were repurchased under the Rule 10b5-1 plan. Future repurchases may be made as open market or privately negotiated transactions as described above. We have no obligation to repurchase stock under this program and may suspend or terminate the repurchase program at any time.
