13. Commitments and Contingencies

Environmental

The Company is involved in a number of environmental remediation investigations and cleanups and, along with other companies, has been identified as a potentially responsible party ("PRP") for certain byproduct disposal sites. While each of these matters is subject to various uncertainties, it is probable that the Company will agree to make payments toward funding certain of these activities, and it is possible that some of these matters will be decided unfavorably to the Company. The Company has evaluated its potential liability and its financial exposure is dependent upon such factors as the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the allocation of cost among potentially responsible parties, the years of remedial activity required and the remediation methods selected.

The Company evaluates its liability for future environmental remediation costs on a quarterly basis. Although actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures, the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with environmental matters in excess of the amounts accrued would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

The following table summarizes information related to the location and undiscounted amount of the Company's environmental liabilities:


(In thousands)	June 30 2026		December 31 2025
Current portion of environmental liabilities (a)	$	8,009	$	9,020
Long-term environmental liabilities	19,105		19,105
Total environmental liabilities	$	27,114	$	28,125

(a) The current portion of environmental liabilities is included in the caption Other current liabilities on the Condensed Consolidated Balance Sheets.

Legal Proceedings

In the ordinary course of business, the Company is a defendant or party to various claims and lawsuits, including those discussed below. Unless stated otherwise below, the Company has not determined a loss to be probable or estimable for the legal proceedings.

On January 27, 2020, the EPA issued a Notice of Potential Liability to the Company, along with several other companies, concerning the Newtown Creek Superfund Site located in Kings and Queens Counties in New York, which alleges certain facilities formerly owned or operated by subsidiaries of the Company may have resulted in the discharge of hazardous substances into Newtown Creek or its Dutch Kills tributary. The site has been subject to CERCLA response activities since approximately 2011. The EPA expects to issue a Record of Decision for the sitewide cleanup plan no sooner than 2028 and announced, in July 2021, that it would defer its decision on a potential early action response for the lower two miles of the Creek until the site-wide studies are completed. On August 28, 2024, the EPA released a proposed plan for clean up of the East Branch portion of Newtown Creek. On January 17, 2025, the EPA released its decision approving this early action remedy for the East Branch. The Company is one of 30 PRPs that have received notices, though it is believed other PRPs may exist. The Company vigorously contests the allegations of this notice and currently does not believe that this matter will have a material effect on the Company’s condensed consolidated financial statements.

The Company has had ongoing meetings with the SCE over processing salt cakes, a processing byproduct, stored at the Al Hafeerah site. The Company’s Bahrain operations that produced the salt cakes have ceased operations. An Environmental Impact Assessment and Technical Feasibility Study for facilities to process the salt cakes was approved by the SCE during the first quarter of 2018. Commissioning of the facilities was completed during the third quarter of 2021 and the processing of the salt cakes has commenced, with the expectation that the Company would be able to sell the products that resulted from the processing in an amount that would cover the processing costs. During the fourth quarter of 2024, the Company concluded that, despite significant commercial efforts and ongoing discussions with the SCE, it could not sufficiently recover the processing costs from these sales as it had previously estimated and, as such, recorded an additional provision of $27.2 million. During the fourth quarter of 2025, the Company recorded an additional provision of $5.0 million based on the current expected recovery of the processing costs, including the agreement to sell a significant quantity of processed material to a regional buyer. The Company is currently exploring other options to resolve this matter in a cost-effective manner, including engaging certain entities to remove the remaining salt cakes from Bahrain, subject to a suitability analysis. The Company's current reserve of $26.5 million at June 30, 2026 represents the Company's best estimate of the net costs to fully resolve this matter. The Company will continue to evaluate this reserve and any future change in estimated costs which could be material to the Company’s results of operations in any single period.

On July 27, 2018, Brazil’s Federal and Rio de Janeiro State Public Prosecution Offices (the "MPF" and "MPE", respectively) filed a Civil Public Action against CSN, one of the Company's customers, the Company’s Brazilian subsidiary, the Municipality of Volta Redonda, Brazil, and the Instituto Estadual do Ambiente, the state of Rio de Janeiro's environmental protection agency, seeking the implementation of various measures to limit and reduce the accumulation of customer-owned slag at the site in Brazil. On August 6, 2018, the 3rd Federal Court in Volta Redonda (the "3rd Volta Redonda Court") granted the MPF and MPE an injunction against the defendants requiring, among other things, CSN and the Company’s Brazilian subsidiary to limit the volume of slag sent to the site. Because the customer owns the site and the slag located on the site, the Company believes that complying with this injunction is the steel producer’s responsibility. Nevertheless, the 3rd Volta Redonda Court issued two orders fining the Company and CSN for what it viewed as violations of the injunction. The Company appealed the fines and the underlying injunction and, beginning on March 25, 2022, the 3rd Volta Redonda Court entered a series of orders suspending the litigation proceedings and staying any additional fines and interest accruals while the parties discuss a possible resolution to the matter. The aggregate amount of fines levied against the Company, exclusive of interest, is approximately 32 million Brazilian reais (or approximately $6 million as of June 30, 2026). On October 5, 2024, the 3rd Volta Redonda Court determined that, as of August 1, 2024, the Company was not responsible for complying with the injunction because the Company no longer operates at the site. In May 2025, the authorities issued a settlement proposal in which CSN would perform remediation at the site and pay approximately 264 million Brazilian reais (or approximately $51 million as of June 30, 2026) and the Company would pay approximately 66 million Brazilian reais (or approximately $13 million as of June 30, 2026) for alleged environmental damage. The Company disputes that environmental damage was caused by the accumulation of slag and, as such, does not agree with the proposed payment. The Company and the other parties continue to discuss a potential resolution related to the portion of the authorities' claims that allegedly occurred prior to August 1, 2024. On September 30, 2025, the public prosecutors pursuing the Civil Public Action initiated a criminal proceeding before the 2nd Federal Court in Volta Redonda (the "2nd Volta Redonda Court") against CSN and the Company and is seeking 431 million Brazilian reais (or approximately $83 million as of June 30, 2026) from the two companies. A majority of the amount sought in this proceeding is identical to, and overlaps with, the damages sought in the Civil Public Action. The 2nd Volta Redonda Court has accepted the complaint from the public prosecutors, and both CSN and the Company submitted their respective defenses in January 2026. The Company denies that any environmental damage occurred and will defend itself vigorously. Because of multiple defenses available, including that the slag is inert and not harmful to the environment, and that the slag deposits do not belong to it, the Company does not believe that a loss relating to this matter is probable.

In October 2021, the Company received a subpoena and two indictments before the Amsterdam District Court in the Netherlands concerning the Company's operations at a customer site in Ijmuiden, Netherlands. The Amsterdam Public Prosecutor’s Office ("APPO") issued two indictments against the Company, alleging violations in connection with dust releases and/or events alleged to have occurred in 2018 through May 2020 at the site. The action cited provisions which permit fines for the alleged infractions and sought €0.1 million in fines with a smaller amount held in abeyance. On February 2, 2022, the APPO announced that it would further investigate residents’ claims related to this matter. On February 25, 2022, the Amsterdam District Court ruled that the Company was liable for only one alleged violation and that this alleged violation was unintentional. The court issued a fine of €5 thousand, to be held in abeyance. Both the Company and the APPO appealed this ruling. On July 19, 2024, the Court of Appeals ruled that the Company was liable for two intentional violations and issued a fine of €25 thousand. Both the Company and the APPO appealed this ruling. On April 23, 2025, the APPO withdrew its appeal of the Court of Appeal's ruling from July 19, 2024 and the Company withdrew its reciprocal appeal on May 8, 2025. As such, the Court of Appeal's July 19, 2024 ruling has become final and binding. The Company is vigorously contesting all allegations against it and is also working with its customer to ensure the control of emissions. The Company has contractual indemnity rights from its customer that it believes will substantially cover any fines or penalties. Due to multiple defenses available to the Company, including that the majority of the alleged issues relate the customer's operations, the Company does not believe a loss is probable or potentially material.

On July 11, 2018, the Company entered into an agreement with Orion Metals Mining Pty Ltd. (“Orion”) to provide slag processing services at Orion’s Highveld facility in South Africa. On October 3, 2018, the Company received a demand letter from Orion, asserting that the Company had failed to maintain minimum monthly processing requirements in breach of said agreement. The parties entered arbitration, with Orion filing a Statement of Claim on February 15, 2019, asserting approximately $29.0 million as of June 30, 2026, exclusive of interest, in damages for alleged claims for misrepresentation, rescission and breach of contract. On September 4, 2019, the Company counterclaimed, asserting approximately $3.5 million as of June 30, 2026 against Orion and its sureties for damages arising from Orion’s unlawful repudiation of the agreement. The matter thereafter became dormant, with Orion taking no action to prosecute its claims for nearly five years. In March 2025, Orion sought to revive the proceedings and its claims. On August 22, 2025, the Company brought a dismissal application seeking an award that Orion’s claims be dismissed for inordinate and inexcusable delay, which Orion has opposed. On June 30, 2026, the arbitrator awarded the Company its costs for the dismissal applications hearing, requested that Orion pay the arbitrator's costs and reduced the amount of interest sought by Orion. The Company vigorously contests all allegations made against it. Due to the multiple defenses and counterclaims available, the Company does not believe a loss is probable or estimable at this time.

Brazilian Tax Dispute

On December 30, 2020, the Company received an assessment from the municipal tax authority in Ipatinga, Brazil, alleging $2.0 million in unpaid service taxes from the period 2015 to 2020. This dispute is currently in the collection action phase of the legal process and the amount assessed includes interest charges that may increase at statutorily determined amounts per month and are assessed on the aggregate amount of the principal and penalties. In addition, while in the collection action phase, the losing party could be subject to a charge to cover statutorily mandated legal fees, which are generally calculated as a percentage of the total assessed amounts due, inclusive of penalty and interest. After calculating the interest and penalties accrued, the Company estimates that the current overall potential liability for this case is approximately $7.9 million as of June 30, 2026. On July 21, 2023, the Company filed the last administrative appeal against the decision that maintained the assessment and a final administrative decision is still pending. Due to the multiple defenses that are available, the Company does not believe a loss is probable and, as a result, no loss provision has been recorded in the Company's Condensed Consolidated Financial Statements and the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with this tax dispute would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

The Company intends to continue its practice of vigorously defending itself against this tax claim under various alternatives, including judicial appeal. The Company will continue to evaluate its potential liability with regard to this claim on a quarterly basis; however, it is not possible to predict the ultimate outcome.

Asbestos Actions

The Company is named as one of many defendants in legal actions in the U.S. alleging personal injury from exposure to airborne asbestos over the past several decades. In their suits, the plaintiffs have named as defendants, among others, many manufacturers, distributors and installers of numerous types of equipment or products that allegedly contained asbestos.

As of June 30, 2026, there were approximately 17,000 pending asbestos personal injury actions filed against the Company. The vast majority of these actions were filed in the New York Supreme Court (New York County), of which the majority of such actions were on the Deferred/Inactive Docket created by the New York Supreme Court in December 2002 for all pending and future asbestos actions filed by persons who cannot demonstrate that they have a malignant condition or discernible physical impairment. A relatively small portion of cases are on the Active or In Extremis docket in New York County or on active dockets in other jurisdictions. The complaints in most of those actions generally follow a form that contains a standard demand of significant damages, regardless of the individual plaintiff's alleged medical condition, and without identifying any Company product.

The Company will continue to vigorously defend against such claims and is confident that it will be successful in doing so. The Company has never been a producer, manufacturer or processor of asbestos fibers. Any asbestos-containing part of a Company product used in the past was purchased from a supplier and the asbestos encapsulated in other materials such that airborne exposure, if it occurred, was not harmful and is not associated with the types of injuries alleged in the pending actions.

The Company has liability insurance coverage under various primary and excess policies that the Company believes will be available, if necessary, to substantially cover any liability that might ultimately be incurred in the asbestos actions referred to above. The costs and expenses of the asbestos actions are being paid by the Company's insurers.

In view of the persistence of asbestos litigation in the U.S., the Company expects to continue to receive additional claims in the future. The Company intends to continue its practice of vigorously defending these claims and cases. As of June 30, 2026, the Company has successfully dismissed approximately 28,500 cases by stipulation or summary judgment prior to trial.

It is not possible to predict the ultimate outcome of asbestos-related actions in the U.S. due to the unpredictable nature of this litigation, and no loss provision has been recorded in the Company's condensed consolidated financial statements because a loss contingency is not deemed probable or estimable. Despite this uncertainty, and although results of operations and cash flows for a given period could be adversely affected by asbestos-related actions, the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with asbestos litigation would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Other

The Company is subject to various other claims and legal proceedings covering a wide range of matters that arose in the ordinary course of business. In the opinion of management, all such matters are adequately covered by insurance or by established reserves, and, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Insurance liabilities are recorded when it is probable that a liability has been incurred for a particular event and the amount of loss associated with the event can be reasonably estimated. Insurance reserves have been estimated based primarily upon actuarial calculations and reflect the undiscounted estimated liabilities for ultimate losses, including claims incurred but not reported. Inherent in these estimates are assumptions that are based on the Company's history of claims and losses, a detailed analysis of existing claims with respect to potential value, and current legal and legislative trends. If actual claims differ from those projected by management, changes (either increases or decreases) to insurance reserves may be required and would be recorded through income in the period the change was determined. When a recognized liability has been determined to be covered by third-party insurance, the Company records an insurance claim receivable to reflect the covered liability. Insurance claim receivables are included in Other receivables on the Company's Condensed Consolidated Balance Sheets. See Note 1, Summary of Significant Accounting Policies in Legacy Enviri's Consolidated Financial Statements in the Company’s Information Statement, under Accrued Insurance and Loss Reserves, for additional information.

Debt Disclosure [Abstract]

Debt and Credit Agreements

10. Debt and Credit Agreements

Long-term debt consists of the following:


(In thousands)	June 30 2026		December 31 2025

Senior Secured Credit Facilities:
Term Loan	$	370,694	$	477,500


Revolving Credit Facility	—		526,000
5.75% Senior Notes	—		475,000
Other financing payable (including finance leases) in varying amounts	21,968		26,763
Total debt obligations	392,662		1,505,263
Less: deferred financing costs	(3,654)		(10,818)
Total debt obligations, net of deferred financing costs	389,008		1,494,445
Less: current maturities of long-term debt	(8,469)		(14,373)
Long-term debt	$	380,539	$	1,480,072

On June 1, 2026, in connection with the completion of the Transactions, the Company repaid $1.2 billion of its outstanding total debt balance, which included the repayment of $628.0 million of borrowings previously outstanding under the Revolving Credit Facility, partial repayment of $105.6 million of the Term Loan and the $475.0 million redemption of the Senior Notes. As a result of these repayments, the Company expensed $3.7 million of previously deferred financing costs pertaining to the Senior Secured Credit Facilities and $1.5 million of previously deferred costs pertaining to the Senior Notes, which are included in Income (loss) from discontinued operations on the Company's Condensed Consolidated Statements of Operations.

In February 2026, the Company amended its Senior Secured Credit Facilities to extend the maturity date of its $50.0 million non-extended revolving credit facility from March 10, 2026 to the earlier of (i) July 1, 2026 and (ii) the date on which the Company's Clean Earth segment is sold to Veolia in connection with the Company's Merger Agreement. As described above, the sale of Clean Earth was completed on June 1, 2026 and, as a result, the $50.0 million portion of the non-extended revolving credit facility was repaid on June 1, 2026. The capacity on the Revolving Credit Facility was reduced to $152.0 million and as a result the Company expensed $2.8 million of previously deferred costs, which are included in the preceding paragraph.

In November 2025, the Company entered into an amendment to the Credit Agreement to, among other things, modify certain levels of its total Net Debt to Consolidated Adjusted EBITDA ratio covenant and permit a distribution of CE, together with certain related transactions, including repayments of certain of the Company's existing indebtedness. The Company obtained the amendment because its forward-looking projections indicated that it may not meet the minimum level required by the net leverage coverage ratio and to allow for the strategic alternatives the Company was evaluating at that time. As a result of this amendment and the distribution of CE, the total Net Debt to Consolidated Adjusted EBITDA ratio covenant was set to 3.00x for the quarter ended June 30, 2026 and for each quarter thereafter. The Company expects that it will maintain compliance with the amended covenants based on current forecasts. The Interest Coverage Ratio remained at 2.50x. The Company capitalized $1.8 million of fees incurred related to the amendment.

In February 2025, the Company entered into an amendment to the Credit Agreement to reset the levels of its covenants, among other changes. As a result of this amendment, the Interest Coverage Ratio was set to a minimum of 2.50x for each quarter ended after December 31, 2024.

At June 30, 2026, as calculated pursuant to the Credit Agreement, the Company was in compliance with all covenants for its Senior Secured Credit Facilities, as the total Net Debt to Consolidated Adjusted EBITDA ratio was 1.94x and the total Interest Coverage Ratio was 4.60x. Based on balances and covenants in effect at June 30, 2026, the Company could increase Net Debt by $160.5 million and still be in compliance with these debt covenants. Alternatively, Consolidated Adjusted EBITDA could decrease by $53.5 million or interest expense could increase by $27.6 million and the Company would remain in compliance with these covenants.

The Company believes it will continue to maintain compliance with these covenants based on its current outlook. However, the Company's estimates of compliance with these covenants could change in the future with a deterioration in economic conditions including softness in certain markets, higher than forecasted interest rate increases, the timing of working capital including the collection of receivables, an inability to realize increased pricing and implement cost reduction initiatives that mitigate the impacts of inflation and other factors that may adversely impact its compliance with covenants.

The Credit Agreement imposes certain restrictions including, but not limited to, restrictions as to types and amounts of debt of liens that may be incurred by the Company; limitations on increases in dividend payments; limitations on repurchases of the Company’s stock and limitations on certain acquisitions by the Company.

With respect to the Senior Secured Credit Facilities, the obligations of the Company are guaranteed by substantially all of the Company’s current and future wholly-owned domestic subsidiaries (“Guarantors”). All obligations under the Senior Credit Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Guarantors.

The Credit Agreement requires certain mandatory prepayments of the Term Loan, subject to certain exceptions, based on net cash proceeds of certain sales or distributions of assets, as well as certain casualty and condemnation events, in some cases subject to reinvestment rights and certain other exceptions; net cash proceeds of any issuance of debt, excluding permitted debt issuances; and a percentage of excess cash flow, as defined by the Credit Agreement, during a fiscal year.

Facility Fees and Debt-Related Income (Expense)

The components of the Condensed Consolidated Statements of Operations caption Facility fees and debt-related income (expense) were as follows:

Accounting Changes and Error Corrections [Abstract]
Recently Adopted and Recently Issued Accounting Standards	2. Recently Adopted and Recently Issued Accounting Standards The following accounting standards were adopted during the six months ended June 30, 2026: The Company adopted a change issued by the FASB that provides an optional practical expedient for estimating future credit losses on current accounts receivable and current contract assets that arise from certain contracts with customers. The adoption of this change did not have a material impact on the Company's financial statements. The Company adopted changes issued by the FASB, which required greater disaggregation of income tax disclosures, related to the income tax rate reconciliation and income taxes paid for each annual reporting period. The Company applied the new disclosure requirements prospectively to its annual report for the year ended December 31, 2025. The adoption of these changes did not have a material impact on the Company's consolidated financial statements. The following accounting standards have been issued and become effective for the Company at a future date: In May 2026, the FASB issued an update that provides authoritative guidance on the recognition, measurement and presentation of environmental credits and compliance obligations that may be settled using environmental credits. This update defines environmental credit obligations and establishes recognition criteria, subsequent measurement and disclosure requirements. This guidance should be applied on a retrospective basis. This update becomes effective starting with the Company's annual financial statements for the year ended December 31, 2028 and includes the interim periods within each annual reporting period. Early adoption is permitted. The Company is currently evaluating the impact that this update will have on the Company's financial statements and disclosures. In December 2025, the FASB issued an update that provides authoritative guidance on the recognition, measurement and presentation of government grants received by business entities. This update defines government grants and establishes recognition criteria and disclosure requirements. This update becomes effective starting with the Company's annual financial statements for the year ended December 31, 2028 and includes the interim periods within each annual reporting period. Early adoption is permitted. The Company is currently evaluating the impact that this update will have on the Company's financial statements. In November 2024, the FASB issued changes which require disaggregated disclosure of income statement expenses within the footnotes to the financial statement for each interim and annual reporting period. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2027 and will be in effect for the Company's interim financial statements after December 31, 2027. The guidance should be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact that this change will have on the Company's disclosures.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2026
Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes* Income tax expense from continuing operations for the three and six months ended June 30, 2026 was $40.5 million and $45.7 million, respectively, compared with $0.9 million and $4.3 million income tax benefit for the three and six months ended June 30, 2025, respectively. The change is primarily due to $34.0 million tax expense related to the valuation allowance establishment of prior year deferred tax assets in the U.S. as a result of the CE divestiture during the three and six months ended June 30, 2026, which did not occur during the three and six months ended June 30, 2025. In addition, no tax benefit was recorded on the total net loss of $207.4 million recognized during the three and six months ended June 30, 2026 related to the Company's decision to exit its contracts with Network Rail and Deutsche Bahn, as well as on the costs of $28.3 million and $29.7 million incurred during the three and six months ended June 30, 2026, respectively, related to the Transactions. The reserve for uncertain tax positions on June 30, 2026 and December 31, 2025 was $6.0 million and $6.7 million, respectively, including interest and penalties. Within the next twelve months, it is reasonably possible that $2.0 million in unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations. * Previously issued 2025 amounts have been revised due to the correction of immaterial errors, as identified in Note 1, Basis of Presentation under "Revision of Previously Issued Financial Statements".

Basis of Presentation (Policies)	Jun. 30, 2026
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The Company has prepared these unaudited condensed consolidated financial statements in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include all information and disclosure required by U.S. GAAP for annual financial statements. The December 31, 2025 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2025 audited consolidated financial statements. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in the Company’s Information Statement (the "Information Statement"), dated May 8, 2026, attached as Exhibit 99.1 to the Company's Current Report on Form 8-K furnished to the SEC on May 11, 2026. In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair statement are reflected in these unaudited Condensed Consolidated Financial Statements. On June 1, 2026, the transactions contemplated by the Separation Agreement and the Merger Agreement, including the Holding Company Merger, the Distribution, the Merger and the Reorganization, were completed, resulting in the Company becoming a separate, publicly traded company that holds the Harsco Environmental and Rail segments and Veolia indirectly holding CE. Due to the size of the Company, the legal spinee, relative to CE Holdings, the legal spinnor, among other factors, Enviri is treated as the "accounting spinnor", notwithstanding the legal form of spin-off. The Company has also determined that Legacy Enviri represents the "accounting predecessor" to Enviri and Enviri represents the "accounting successor" to Legacy Enviri for accounting purposes. Therefore, the historical financial statements of Enviri, with respect to periods prior to June 1, 2026, are represented by the historical consolidated financial statements of Legacy Enviri, with CE reported as discontinued operations in accordance with ASC 205-20, Discontinued Operations. Therefore, the Company's Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2025 have been recast to reflect the after tax operating results of CE in Income (loss) from discontinued operations, net of tax. In addition, certain costs related to the Transactions, interest expense related to the portion of the Company's total debt that was required to be repaid on June 1, 2026 and fees related to the Company's AR Facility that was required to be terminated at the closing of the Transactions, are also allocated to Income (loss) from discontinued operations, net of tax. CE's assets and liabilities have been reclassified as held-for-sale in the Company's Consolidated Balance Sheets as of December 31, 2025, which were previously classified as held-for-use. All disclosures have been updated to reflect these changes. See Note 4, Dispositions for additional information. The completion of the Transactions resulted in the exchange of one share of CE Holdings common stock for one share of Legacy Enviri common stock, and subsequently one share of Enviri common stock for every three shares of CE Holdings common stock. As such, the weighted-average shares outstanding and all earnings per share data for periods prior to the Transaction have been retrospectively adjusted to reflect the impact of the Transactions on the Company's capital structure
Reclassifications	Reclassifications Reclassifications have been made to prior year amounts to conform with current year classifications. These reclassifications did not have a material impact on the Company's Condensed Consolidated Financial Statements, including the notes thereto.
Recently Adopted and Recently Issued Accounting Standards	2. Recently Adopted and Recently Issued Accounting Standards The following accounting standards were adopted during the six months ended June 30, 2026: The Company adopted a change issued by the FASB that provides an optional practical expedient for estimating future credit losses on current accounts receivable and current contract assets that arise from certain contracts with customers. The adoption of this change did not have a material impact on the Company's financial statements. The Company adopted changes issued by the FASB, which required greater disaggregation of income tax disclosures, related to the income tax rate reconciliation and income taxes paid for each annual reporting period. The Company applied the new disclosure requirements prospectively to its annual report for the year ended December 31, 2025. The adoption of these changes did not have a material impact on the Company's consolidated financial statements. The following accounting standards have been issued and become effective for the Company at a future date: In May 2026, the FASB issued an update that provides authoritative guidance on the recognition, measurement and presentation of environmental credits and compliance obligations that may be settled using environmental credits. This update defines environmental credit obligations and establishes recognition criteria, subsequent measurement and disclosure requirements. This guidance should be applied on a retrospective basis. This update becomes effective starting with the Company's annual financial statements for the year ended December 31, 2028 and includes the interim periods within each annual reporting period. Early adoption is permitted. The Company is currently evaluating the impact that this update will have on the Company's financial statements and disclosures. In December 2025, the FASB issued an update that provides authoritative guidance on the recognition, measurement and presentation of government grants received by business entities. This update defines government grants and establishes recognition criteria and disclosure requirements. This update becomes effective starting with the Company's annual financial statements for the year ended December 31, 2028 and includes the interim periods within each annual reporting period. Early adoption is permitted. The Company is currently evaluating the impact that this update will have on the Company's financial statements. In November 2024, the FASB issued changes which require disaggregated disclosure of income statement expenses within the footnotes to the financial statement for each interim and annual reporting period. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2027 and will be in effect for the Company's interim financial statements after December 31, 2027. The guidance should be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact that this change will have on the Company's disclosures.

Derivative Instruments, Hedging Activities and Fair Value

16. Derivative Instruments, Hedging Activities and Fair Value

Derivative Instruments and Hedging Activities

The Company uses derivative instruments, including foreign currency exchange forward contracts and interest rate swaps, to manage certain foreign currency and interest rate exposures. Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes. All derivative instruments are recorded on the Company's Condensed Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs, such as forward rates, interest rates, the Company’s credit risk and counterparties’ credit risks, and which minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the ability to observe those inputs. Foreign currency exchange forward contracts and interest rate swaps are based upon pricing models using market-based inputs (Level 2). Model inputs can be verified and valuation techniques do not involve significant management judgment.

The fair value of outstanding derivative contracts recorded as assets and liabilities on the Company's Condensed Consolidated Balance Sheets was as follows:


(In thousands)	Balance Sheet Location	Fair Value of Derivatives Designated as Hedging Instruments		Fair Value of Derivatives Not Designated as Hedging Instruments		Total Fair Value
June 30, 2026
Asset derivatives (Level 2):
Foreign currency exchange forward contracts	Other current assets	$	131	$	6,960	$	7,091
Interest rate swaps	Other current assets	2,523		—		2,523
Interest rate swaps	Other assets	1,763		—		1,763
Total		$	4,417	$	6,960	$	11,377

December 31, 2025
Asset derivatives (Level 2):
Foreign currency exchange forward contracts	Other current assets	$	36	$	1,340	$	1,376


Interest rate swaps	Other current assets	887		—		887
Interest rate swaps	Other assets	313		—		$	313
Total		$	1,236	$	1,340	$	2,576

Liability derivatives (Level 2):
Foreign currency exchange forward contracts	Derivative liabilities	$	861	$	19,978	$	20,839


Total		$	861	$	19,978	$	20,839

All of the Company's derivatives are recorded on the Condensed Consolidated Balance Sheets at gross amounts and do not offset. All of the Company's interest rate swaps and certain foreign currency exchange forward contracts are transacted under ISDA documentation. Each ISDA master agreement permits the net settlement of amounts owed in the event of default. The Company's derivative assets and liabilities subject to enforceable master netting arrangements, if offset, would have resulted in a net asset of $2.9 million at June 30, 2026 and a $0.3 million net liability at December 31, 2025.

The effect of derivative instruments on the Company's Condensed Consolidated Statements of Comprehensive Income (Loss) was as follows:

Foreign currency exchange forward contracts	Cost of services and products sold	$	2,623	$	(30,981)	$	14,109	$	(46,137)

(a) These gains (losses) offset other amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

Foreign Currency Exchange Forward Contracts

The Company conducts business in multiple currencies and, accordingly, is subject to the inherent risks associated with foreign exchange rate movements. Foreign currency-denominated assets and liabilities are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods.

The Company uses derivative instruments to hedge cash flows related to foreign currency fluctuations. Foreign currency exchange forward contracts outstanding are part of a worldwide program to minimize foreign currency exchange operating income and balance sheet exposure by offsetting foreign currency exposures of certain future payments between the Company and various subsidiaries, suppliers or customers. The unsecured contracts are with major financial institutions. The Company may be exposed to credit loss in the event of non-performance by the contract counterparties. The Company evaluates the creditworthiness of the counterparties and does not expect default by them. Foreign currency exchange forward contracts are used to hedge commitments, such as foreign currency debt, firm purchase commitments and foreign currency cash flows for certain export sales transactions.

Changes in the fair value of derivatives used to hedge foreign currency denominated balance sheet items are reported directly in earnings, along with offsetting transaction gains and losses on the items being hedged. Derivatives used to hedge forecasted cash flows associated with foreign currency commitments may be accounted for as cash flow hedges, as deemed appropriate, if the criteria for hedge accounting are met. Gains and losses on derivatives designated as cash flow hedges are deferred in AOCI, a separate component of equity, and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions. The ineffective portion of all hedges, if any, is recognized currently in earnings.

The recognized gains and losses offset amounts recognized in cost of services and products sold principally as a result of intercompany or third-party foreign currency exposures. At June 30, 2026 and December 31, 2025, the notional amounts of foreign currency exchange forward contracts were $627.7 million and $639.0 million, respectively. These contracts are primarily denominated in British Pound Sterling and Euros and mature through February 2028.

In addition to foreign currency exchange forward contracts, the Company designates certain loans as hedges of net investments in international subsidiaries. The Company recorded pre-tax net gains of $0.6 million and $0.7 million for the three and six months ended June 30, 2026, respectively, and pre-tax net losses $1.3 million of $1.9 million for the three and six months ended June 30, 2025, respectively, in OCI.

Interest Rate Swaps

The Company uses interest rate swaps in conjunction with certain variable rate debt issuances in order to secure a fixed interest rate. Changes in the fair value attributed to the effect of the swaps’ interest spread and changes in the credit worthiness of the counter-parties are recorded in OCI.

The Company has entered into a series of interest rate swaps that have been effective since December 2025 and are scheduled to mature in March 2028. These forward swaps have the effect of converting $300.0 million under the Term Loan from a floating interest rate to a fixed interest rate and are classified as cash flow hedges. These swaps provide fixed interest rates that range from 3.06% to 3.12% and replace the adjusted SOFR rate in the interest calculation.

Fair Value of Other Financial Instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and short-term borrowings approximate fair value due to the short-term maturities of these assets and liabilities. At June 30, 2026 and December 31, 2025, the total fair value of long-term debt and current maturities, excluding deferred financing costs, was $391.3 million and $1,504.7 million, respectively, compared with a carrying value of $392.7 million and $1,505.3 million, respectively. Fair values for debt are based on pricing models using market-based inputs (Level 2) for similar issues or on the current rates offered to the Company for debt of the same remaining maturities.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The Company has prepared these unaudited condensed consolidated financial statements in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include all information and disclosure required by U.S. GAAP for annual financial statements. The December 31, 2025 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2025 audited consolidated financial statements. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in the Company’s Information Statement (the "Information Statement"), dated May 8, 2026, attached as Exhibit 99.1 to the Company's Current Report on Form 8-K furnished to the SEC on May 11, 2026. In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair statement are reflected in these unaudited Condensed Consolidated Financial Statements. On June 1, 2026, the transactions contemplated by the Separation Agreement and the Merger Agreement, including the Holding Company Merger, the Distribution, the Merger and the Reorganization, were completed, resulting in the Company becoming a separate, publicly traded company that holds the Harsco Environmental and Rail segments and Veolia indirectly holding CE. Due to the size of the Company, the legal spinee, relative to CE Holdings, the legal spinnor, among other factors, Enviri is treated as the "accounting spinnor", notwithstanding the legal form of spin-off. The Company has also determined that Legacy Enviri represents the "accounting predecessor" to Enviri and Enviri represents the "accounting successor" to Legacy Enviri for accounting purposes. Therefore, the historical financial statements of Enviri, with respect to periods prior to June 1, 2026, are represented by the historical consolidated financial statements of Legacy Enviri, with CE reported as discontinued operations in accordance with ASC 205-20, Discontinued Operations. Therefore, the Company's Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2025 have been recast to reflect the after tax operating results of CE in Income (loss) from discontinued operations, net of tax. In addition, certain costs related to the Transactions, interest expense related to the portion of the Company's total debt that was required to be repaid on June 1, 2026 and fees related to the Company's AR Facility that was required to be terminated at the closing of the Transactions, are also allocated to Income (loss) from discontinued operations, net of tax. CE's assets and liabilities have been reclassified as held-for-sale in the Company's Consolidated Balance Sheets as of December 31, 2025, which were previously classified as held-for-use. All disclosures have been updated to reflect these changes. See Note 4, Dispositions for additional information. The completion of the Transactions resulted in the exchange of one share of CE Holdings common stock for one share of Legacy Enviri common stock, and subsequently one share of Enviri common stock for every three shares of CE Holdings common stock. As such, the weighted-average shares outstanding and all earnings per share data for periods prior to the Transaction have been retrospectively adjusted to reflect the impact of the Transactions on the Company's capital structure Reclassifications Reclassifications have been made to prior year amounts to conform with current year classifications. These reclassifications did not have a material impact on the Company's Condensed Consolidated Financial Statements, including the notes thereto. Revision of Previously Issued Financial Statements During the year ended December 31, 2025, management identified certain errors related to the measurement of certain aspects of the defined benefit pension obligation associated with the U.K. pension plan (the “Plan”) administered by the Company. The errors related to the historic application of certain provisions governing pension benefits in the actuarial estimation of the liabilities for certain acquired pension plans merged into the Plan. The errors were identified by the Company during a review of the Plan in preparation for the potential buy-out of the Plan’s liabilities by an insurance company. Management evaluated the identified errors in accordance with ASC 250, Accounting Changes and Error Corrections, and applicable SEC guidance, including SAB 99, considering both quantitative and qualitative factors. Management concluded that the errors were not material to the Company’s previously issued consolidated financial statements for any individual period. However, due to the cumulative impact of these errors, the Company revised the prior-period financial statements. The revisions primarily affected Retirement plan assets and Retained earnings with corresponding impacts to Defined benefit pension income (expense) and Accumulated other comprehensive income (loss). In connection with the revision, the Company also corrected other previously identified immaterial errors. The revision did not impact the Company’s previously reported net cash flows or compliance with debt covenants.

(a) Revenues are attributed to individual countries based on the location of the facility generating the revenue.

(b) Includes Mexico.

The Company may receive payments in advance of earning revenue (advances on contracts), which are included in Current portion of advances on contracts and Other liabilities on the Condensed Consolidated Balance Sheets. The Company may recognize revenue in advance of being able to contractually invoice the customer (contract assets), which is included in Current portion of contract assets and Other assets on the Condensed Consolidated Balance Sheets. Contract assets are transferred to Trade accounts receivable, net, when the right to payment becomes unconditional. Contract assets and advances on contracts are reported as a net position, on a contract-by-contract basis, at the end of each reporting period. These instances are primarily related to Rail.

The Company had contract assets totaling $32.5 million and $69.1 million at June 30, 2026 and December 31, 2025, respectively. The Company had advances on contracts totaling $9.0 million and $8.2 million at June 30, 2026 and December 31, 2025, respectively. The decrease in contract assets is due principally to the Company's decision to exit the Network Rail and Deutsche Bahn contracts, as discussed in further detail in Note 3, Contract Exits. During the three and six months ended June 30, 2026, the Company recognized $1.4 million and $6.1 million, respectively, of revenue related to amounts previously included in advances on contracts. During the three and six months ended June 30, 2025, the Company recognized revenues of $4.8 million and $22.4 million, respectively, related to amounts previously included in advances on contracts.

The table below represents the expected fulfillment year of Company's fixed, unsatisfied performance obligations, where the expected contract duration exceeds one year, by segment, and excludes any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year:

Rail has been manufacturing ETO equipment under significant long-term, fixed-price contracts with SBB, Network Rail, and Deutsche Bahn. As previously disclosed, the Company had recognized estimated forward loss provisions related to these contracts due to several factors, such as material and labor cost inflation, supply chain delays, the bankruptcy of key vendors, increased engineering efforts and challenges encountered with homologation and commissioning of equipment.

As discussed in Note 3, Contract Exits, the Company recorded a loss of $207.4 million during the second quarter of 2026 related to the exits of the Network Rail and Deutsche Bahn contracts.

For the Network Rail contract, during the three months ended June 30, 2025, the Company recorded a forward loss provision of $10.2 million primarily related to increased estimated manufacturing and material costs. For the six months ended June 30, 2025, the forward loss provision totaled $11.3 million.

For the three months ended June 30, 2025, no adjustment was made to the forward loss provision for the Deutsche Bahn contract. During the six months ended June 30, 2025, the Company recorded a net favorable adjustment of $13.3 million that was the result of an amendment to the contract with Deutsche Bahn which included additional pricing, as well as an extension of the delivery schedule for the machines which resulted in a reduction of the previous estimate of penalties. The increased pricing and reduction of penalties were recorded as an increase to revenue. Partially offsetting this were higher estimated material, manufacturing and engineering costs.

The Company continues to manufacture equipment under the SBB contract. For the six months ended June 30, 2026, no adjustment was made to the forward loss provision. For the three months ended June 30, 2025, the Company recorded a loss provision of $4.8 million due to higher estimated commissioning, manufacturing, assembly, and logistics costs due as progress was made towards prototype commissioning of the universal vehicle during the quarter. For the six months ended June 30, 2025, the forward loss provision totaled $5.9 million.

The estimated forward loss provision for the SBB contract represents the Company's best estimate based on currently available information. It is possible that the Company's overall estimate of costs to complete this contract may change, which could result in an additional estimated forward loss provision at such time that could be material in any one period.

As of June 30, 2026, the contract with SBB is 92% complete, based on costs incurred under the cost-to-cost method to measure progress.

The Company provides assurance type warranties primarily for product sales at Rail. These warranties are typically not priced or negotiated separately (there is no option to separately purchase the warranty) or the warranty does not provide customers with a service in addition to the assurance that the product complies with agreed-upon specifications. Accordingly, such warranties do not represent separate performance obligations.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Goodwill and Other Intangible Assets

9. Goodwill and Other Intangible Assets

The Company tests for goodwill impairment annually, or more frequently if indicators of impairment exist, or if a decision is made to dispose of a business. The Company performs its annual goodwill impairment test as of October 1 and monitors for triggering events on an ongoing basis.

During the six months ended June 30, 2026, the Company determined that there were no events or indicators present that would indicate that it was more-likely-than-not that its reporting unit's fair value was less than its carrying amount, which would require a further interim impairment analysis. However, unfavorable economic conditions, including continued cost inflation, could impact the Company's future projected cash flows and discount rates used to estimate fair value, which could result in an impairment charge to the Company's reporting unit in a future period.

Contract Exits	6 Months Ended
Contract Exits	Jun. 30, 2026
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Contract Exits	3. Contract Exits Rail had been manufacturing engineered-to-order ("ETO") equipment under significant long-term, fixed-price contracts with Network Rail and Deutsche Bahn. In June 2026, the Company informed Network Rail that it had ceased all activities relating to its ETO contract to build stoneblower rail maintenance vehicles, and the associated manufacturing facilities have been closed. Also, in June 2026, the Company ceased all activities relating to its ETO contract to deliver utility track vehicles with Deutsche Bahn. As a result of these actions, the Company recorded a loss of $207.4 million during the quarter ended June 30, 2026, which includes the non-cash impairment charges of $40.5 million related to net contract assets, $21.5 million of inventory and $12.9 million of prepaid balances specific to the projects, as well as an estimated incremental liability of approximately $133 million to address future obligations related to these contracts. Of this loss, $136.5 million was recorded as a reduction to Product revenues - Rail contract exit-related adjustments and $70.9 million to Costs of products sold - Rail contract exit-related adjustments in the Condensed Consolidated Statements of Operations. On August 10, 2026, Network Rail notified the Company of its alleged breach under the contract and its intention to reach resolution of contractual damages as a result. The Company intends to vigorously contest any damages based on multiple available defenses. Additionally, the Company has proposed an alternative solution to assist Network Rail in significantly extending the life of their existing fleet of stoneblower machines. It is possible that the estimate of the loss could change based on ongoing discussions with Network Rail, or if the ultimate outcome to this matter were to be determined through litigation. On August 10, 2026, the Company entered into a definitive agreement with Gleisbaumechanik Brandenburg GmbH ("GBM"), a manufacturing partner on the Deutsche Bahn contract, to sell all assets related to the contract, including inventory and intellectual property, to GBM. Through the proceeds from the CE Holdings Note set aside in the Company's initial balance sheet subsequent to the closing of the Transactions, the Company has sufficient cash available to settle any cash payments required to exit these contracts.
