ENVIRI CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

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, 2023 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2023 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 Annual Report on Form 10-K for the year ended December 31, 2023. 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.

Liquidity

The Company’s cash flow forecasts, combined with existing cash and cash equivalents and borrowings available under the Senior Secured Credit Facilities, indicate sufficient liquidity to fund the Company’s operations for at least the next twelve months. As such, the Company’s unaudited Consolidated Financial Statements have been prepared on the basis that it will continue as a going concern for a period extending beyond twelve months from the date the unaudited Consolidated Financial Statements are issued. This assessment includes the expected ability to meet required financial covenants and the continued ability to draw down on the Senior Secured Credit Facilities (see Note 9, Debt and Credit Agreements).

Reclassifications

During the three months ended March 31, 2024, the Company determined that the held-for-sale criteria for Rail was no longer met and, as a result, the Company made reclassifications to prior year amounts previously classified as discontinued operations and assets held-for-sale in the Company's Consolidated Statements of Operations and Consolidated Balance Sheets, along with the accompanying notes to the Company's Consolidated Financial Statements. See Note 3, Discontinued Operations and Dispositions for further details.

2. Recently Adopted and Recently Issued Accounting Standards

The Company has not adopted any accounting standards during the first quarter in 2024:

The following accounting standards have been issued and become effective for the Company at a future date:

In November 2023, the FASB issued changes that require expansion of annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2024. The Company is currently evaluating the impact that this change will have on the Company's disclosures.

In December 2023, the FASB issued changes which require greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2025. 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.

3. Discontinued Operations and Dispositions

Harsco Rail Segment

The results of the Rail business were previously presented as discontinued operations. However, the held for sale criteria were no longer met as of March 31, 2024 as the sales process has been paused. The assets and liabilities of the Rail business, previously presented as held for sale, have been reclassified to held and used in the Condensed Consolidated Balance Sheets as of December 31, 2023, and the results of the Rail business have been reclassified from discontinued operations to continuing operations for all periods presented in the Condensed Consolidated Statements of Operations. The Rail business’ assets and liabilities as of March 31, 2024 were measured at the carrying amount before the assets were classified as held for sale, reduced by $10.7 million representing the depreciation and amortization expense that would have been recognized had the assets been continuously classified as held for use. The $10.7 million reduction to the carrying value of the Rail assets was reported in Remeasurement of long-lived assets in the first quarter of 2024.

The reclassification of the Rail business's balance sheet positions as of December 31, 2023 had the following impacts on the Condensed Consolidated Balance Sheets and are summarized as follows:

Accounts Receivable Securitization Facility

In June 2022, the Company and its SPE entered into an AR Facility with PNC Bank, National Association ("PNC") to accelerate cash flows from trade accounts receivable. The AR Facility has a three-year term. The maximum purchase commitment by PNC is $150.0 million.

The total outstanding balance of trade receivables that have been sold and derecognized by the SPE is $150.0 million as of March 31, 2024 and December 31, 2023. The SPE owned $71.6 million and $82.2 million of trade receivables as of March 31, 2024 and December 31, 2023, respectively, which is included in the caption Trade accounts receivable, net, on the Condensed Consolidated Balance Sheets. See Note 9, Debt and Credit Agreements, for AR Facility expenses incurred.

The Company received proceeds of $5.0 million from the AR Facility in the first quarter of 2023.

Factoring Arrangements

The Company maintains factoring arrangements with a financial institution to sell certain accounts receivable that are also accounted for as a sale of financial assets and accordingly, derecognized from the Company's Consolidated Balance Sheet. The following table reflects balances for net amounts sold and program capacities for the arrangements:

Net amounts sold under factoring arrangements	$	14.7	$	16.1
Program capacities	32.0		32.6

Note Receivable

In January 2020, the Company sold IKG for $85.0 million including cash and a note receivable, subject to post-closing adjustments. The note receivable from the buyer has a face value of $40.0 million, bearing interest at 2.50%, that is paid in kind and matures on January 31, 2027. Any unpaid principal, along with any accrued but unpaid interest is payable at maturity. Prepayment is required in case of a change in control or a percentage of excess cash flow, as defined in the note receivable agreement. Because there are no scheduled payments under the terms of the note receivable, the balance is classified as noncurrent as of March 31, 2024 and December 31, 2023, and is included in the caption Other assets on the Condensed Consolidated Balance Sheet at amortized cost.

8. 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 three months ended March 31, 2024, the Company determined that there were no events or indicators present that would indicate that it was more-likely-than-not that its reporting units' fair values were less than their carrying amounts, which would require a further interim impairment analysis. However, unfavorable economic conditions, including continued cost inflation and labor shortages, as well as rising interest rates, 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 any of the Company's reporting units in a future period.

Table of Contents

The Senior Secured Credit Facilities contain a consolidated net debt to Consolidated Adjusted EBITDA ratio covenant, which is not to exceed 5.25x for the quarter ended March 31, 2024 and then decreasing quarterly until reaching 4.00x on December 31, 2024. The total net leverage ratio covenant applicable to the third quarter of 2024 and earlier is subject to a 0.50x decrease upon the divestiture of Rail. The Company's required coverage of consolidated interest charges is set at a minimum of 2.75x through the end of 2024, subject to an increase to 3.00x upon closing of the divestiture of Rail, and 3.00x beginning with the first quarter of 2025.

At March 31, 2024, the Company was in compliance with its debt covenants under the Senior Secured Credit Facilities, with a total net debt to Consolidated Adjusted EBITDA ratio of 4.08x and a total interest coverage ratio of 3.06x. 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, higher than forecasted interest rate increases, the timing of working capital including the collection of receivables or 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 realized operating margins.

Cash contributions to U.S. and international defined benefit pension plans totaled $0.4 million and $4.3 million for the three months ended March 31, 2024, respectively. The Company's estimate of expected cash contributions to be paid during the remainder of 2024 for the U.S. and international defined benefit pension plans is $7.3 million and $13.2 million, respectively.

11. Income Taxes

Income tax expense from continuing operations for the three months ended March 31, 2024 and 2023 was $7.9 million and $8.0 million, respectively. The decrease in expense for the three months ended March 31, 2024, compared with the three months ended March 31, 2023, is primarily due to a decrease in disallowed interest expense and business improvement in various countries with no tax expense.

For the three months ended March 31, 2024, the Company calculated its quarterly tax provision based on its best estimate of the full year tax rate applicable to the quarter. For the three months ended March 31, 2023, due to the insignificant amount of pre-tax book loss relative to the size of permanent book-tax differences and a varying net income (loss) pattern projected for the year, the Company’s tax provision estimate was determined using an actual year-to-date method.

The reserve for uncertain tax positions on March 31, 2024 and December 31, 2023 was $3.4 million, including interest and penalties. Within the next twelve months, it is reasonably possible that $0.6 million in unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.

12. 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” 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)	March 31 2024		December 31 2023
Current portion of environmental liabilities (a)	$	7,395	$	7,540
Long-term environmental liabilities	25,253		25,682
Total environmental liabilities	$	32,648	$	33,222

(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.

In November 2022, the EPA and the Kentucky Department for Environmental Protection (the “KDEP”) conducted an inspection of Clean Earth of Calvert City LLC’s facility in Calvert City, KY. In September 2023, the EPA verbally proposed a civil penalty of $0.8 million to address alleged violations identified at the time of the inspection. The Company recorded a liability during the year ended December 31,2023 of $0.7 million. At March 31, 2024, the liability is $0.7 million and the Company is still assessing the alleged violations and is engaging with the EPA to resolve this matter.

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. The Notice 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 sitewide studies are completed. The Company is one of approximately twenty (20) Potentially Responsible Parties ("PRPs") that have received notices, though it is believed other PRPs may exist. The Company vigorously contests the allegations of the Notice and currently does not believe that this matter will have a material effect on the Company’s financial position or results from operations.

On June 25 and 26, 2018, the DTSC conducted a compliance enforcement inspection of ESOL’s facility in Rancho Cordova, California, which was then owned by Stericycle, Inc. On February 14, 2020, the DTSC filed an action in the Superior Court for the State of California, Sacramento Division, alleging violations of California’s Hazardous Waste Control Law and the facility’s hazardous waste permit arising from the inspection. On August 27, 2020, the DTSC issued a Notice of Denial of Hazardous Waste Facility Permit Application, denying the renewal of the facility's hazardous waste permit. The Company has exhausted its legal challenges to the denial of the Hazardous Waste facility permit, and the hazardous waste facility is in the process of closing. The Company continues to utilize the site for non-hazardous waste and is evaluating additional potential alternate uses for the site. The DTSC investigation and compliance issues leading to the compliance tier assignment were ongoing well before the Company's acquisition of the ESOL business, and the Company was aware of the investigation and many of the issues raised in the investigation at the time of the purchase. Accordingly, the Company is indemnified for certain fines and other costs and expenses associated with this matter by Stericycle, Inc. The Company has not accrued any amounts in respect of these alleged violations and cannot estimate the reasonably possible loss or the range of reasonably possible losses that it may incur.

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 has 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. The Company's current reserve of $5.1 million at March 31, 2024 continues to represent the Company's best estimate of the ultimate costs to be incurred to resolve this matter. The Company continues to evaluate this reserve and any future change in estimated costs which could be material to the Company’s results of operations in any one 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 (local 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 "Volta Redonda Court") granted the MPF and MPE an injunction against the same parties 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 Volta Redonda Court issued two orders fining the Company and CSN for what it views as ongoing violations of the injunction. The Company is appealing the fines and the underlying injunction. Both the Company and CSN continue to have discussions with the MPF, MPE and the governmental authorities regarding the injunction and the possible resolution of the underlying case. Beginning on March 25, 2022, the Courts 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 March 31, 2024. The Company does not believe that a loss relating to this matter is probable or estimable at this point.

On October 19, 2018, local environmental authorities issued an enforcement action against the Company concerning the Company’s operations at a customer site in Ijmuiden, Netherlands. The enforcement action alleged violations of the Company’s environmental permit at the site, which restricts the release of any visible dust emissions. On January 12, 2022, the Administrative Supreme Court of the Netherlands upheld the Company’s challenge of these enforcement actions as they relate to the slag tipping area of the site. As a result, all fines asserted against the Company to date have been invalidated and all fines paid to date have been reimbursed. This order is not appealable. On or about October 14, 2021, the Company received a subpoena and two indictments before the Amsterdam District Court in the 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 cites provisions which permit fines for the alleged infractions and seeks €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 €5,000, to be held in abeyance. Both the Company and the APPO have appealed this ruling. 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.

DEA Investigation

Prior to the Company’s acquisition of ESOL, Stericycle, Inc. notified the Company that the DEA had served an administrative subpoena on Stericycle, Inc. and executed a search warrant at a facility in Rancho Cordova, CA and an administrative inspection warrant at a facility in Indianapolis, IN. The Company has determined that the DEA and the DTSC have launched investigations involving, at least in part, the ESOL business of collecting, transporting, and destroying controlled substances from retail customers that transferred from Stericycle, Inc. to the Company. The Company is cooperating with these inquiries, which relate primarily to the period before the Company owned the ESOL business. Since the acquisition of the ESOL business, the Company has performed a vigorous review of ESOL’s compliance program related to controlled substances and has made material changes to the manner in which controlled substances are transported from retail customers to DEA-registered facilities for destruction. Pursuant to an agreement with Stericycle, the Company has contractual recourse for any material loss the Company has determined is reasonably possible. The Company has not accrued any amounts in respect of these investigations and does not believe a loss is reasonably possible.

Brazilian Tax Disputes

The Company is involved in a number of tax disputes with federal, state and municipal tax authorities in Brazil. These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest charges that increase at statutorily determined amounts per month and are assessed on the aggregate amount of the principal and penalties. In addition, at the collection action or court of appeals 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. Many of the claims relate to ICMS, services and social security tax disputes. The largest proportion of the assessed amounts relate to ICMS claims filed by the SPRA, encompassing the period from January 2002 to May 2005.

In October 2009, the Company received notification of the SPRA’s final administrative decision regarding the levying of ICMS in the State of São Paulo in relation to services provided to a customer in the State between January 2004 and May 2005. As of March 31, 2024, the principal amount of the tax assessment from the SPRA with regard to this case is approximately $1.2 million, with penalty, interest and fees assessed to date increasing such amount by an additional $18.6 million. On June 4, 2018, the Appellate Court of the State of São Paulo ruled in favor of the SPRA, but ruled that the assessed penalty should be reduced to approximately $1.2 million. After calculating the interest accrued on the penalty through March 31, 2024, the Company estimates that this ruling reduced the current overall potential liability for this case to approximately $8.1 million. All such amounts include the effect of foreign currency translation. The Company has appealed the ruling in favor of the SPRA to the Superior Court of Justice. Due to multiple court precedents in the Company’s favor, the Company does not believe a loss is probable.

Another ICMS tax case involving the SPRA refers to the tax period from January 2002 to December 2003. In December 2018, the administrative tribunal hearing the case upheld the Company's liability. The aggregate amount assessed by the tax authorities in August 2005 was $5.0 million (the amounts with regard to this claim are valued as of the date of the assessment, since it has not yet reached the collection phase), composed of a principal amount of $1.2 million, with penalty and interest assessed through that date increasing such amount by an additional $3.8 million. On December 6, 2018, the administrative tribunal reduced the applicable penalties to $0.6 million. After calculating the interest accrued on the current penalty through March 31, 2024, the Company estimates that the current overall liability for this case to be approximately $5.6 million. All such amounts include the effect of foreign currency translation. The Company has appealed to the judicial phase at the Third Trial Court of the District of Cubatão, State of São Paulo. On October 14, 2022, the District Court issued a decision holding that the Company is not liable for the taxes at issue. The SPRA appealed this decision on December 28, 2022 to the Appellate Court of the State of São Paulo (the "São Paulo Appellate Court"). On March 26, 2024, the São Paulo Appellate Court ruled that the Company is liable for the taxes at issue. In the same decision, the São Paulo Appellate Court also ruled in the Company's favor regarding the applicable tax rate. Due to multiple court precedents in the Company's favor, the Company does not believe a loss is probable.

The Company continues to believe that sufficient coverage for these claims exists as a result of the indemnification obligations of the Company's customer and such customer’s pledge of assets in connection with the October 2009 notice, as required by Brazilian law. On April 23, 2024, the Company’s customer directed the Company to accept a settlement offer made by SPRA and the Company accepted the settlement offer on April 26, 2024. Under the settlement, the Company will pay a total of $3.8 million over sixty months in return for a full release from the SPRA as to both claims. Pursuant to our contractual rights, the Company is indemnified by its customer for these amounts; therefore, no net loss has been recorded by the Company for this settlement.

Table of Contents

On December 30, 2020, the Company received an assessment from the municipal authority in Ipatinga, Brazil alleging $2.1 million in unpaid service taxes from the period 2015 to 2020. After calculating the interest and penalties accrued, the Company estimates that the current overall potential liability for this case to be approximately $5.8 million. 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.

The Company intends to continue its practice of vigorously defending itself against these tax claims under various alternatives, including judicial appeal. The Company will continue to evaluate its potential liability with regard to these claims on a quarterly basis; however, it is not possible to predict the ultimate outcome of these tax-related disputes in Brazil. No loss provision has been recorded in the Company's Condensed Consolidated Financial Statements for the disputes described above because the loss contingency is not deemed probable, and the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with Brazilian tax disputes would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

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.

At March 31, 2024, 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. At March 31, 2024, the Company has successfully dismissed approximately 28,400 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

On November 5, 2020, a worker suffered a fatal injury at a site owned by the Company’s customer, Gerdau Ameristeel US, Inc. ("Gerdau"), in Midlothian, TX. Although the Company was not directly involved in the accident, the worker was employed by a sub-contractor of a sub-contractor of the Company. The worker’s family filed suit in the 125th Judicial District Court of Harris County, TX against multiple parties, including the Company, seeking monetary damages. On May 11, 2023, the parties completed a formal settlement agreement, settling the claims brought by the worker's family. The Company paid its insurance deductible of $5.0 million and has recorded an indemnification receivable from Gerdau for the recovery of certain losses based upon the contractual indemnity rights. On August 25, 2023, the Company initiated arbitration proceedings against Gerdau before the American Arbitration Association to enforce its contractual indemnity rights. There can be no assurances that the Company's position will ultimately prevail; however, any financial statement impact is not expected to be material.

Table of Contents

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 Part II, Item 8 Financial Statements and Supplementary Data in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, under Accrued Insurance and Loss Reserves, for additional information.

14. 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.

Table of Contents

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
March 31, 2024
Asset derivatives (Level 2):

Interest rate swaps	Other liabilities	2,150		—		2,150
Total		$	2,711	$	8,064	$	10,775

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 $0.8 million and a net liability of $0.5 million at March 31, 2024 and December 31, 2023, respectively.

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

(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 consolidated 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 March 31, 2024 and December 31, 2023, the notional amounts of foreign currency exchange forward contracts were $648.5 million and $633.3 million, respectively. These contracts are primarily denominated in British Pound Sterling and Euros and mature through 2025.

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 $0.8 million and $0.3 million for the three months ended March 31, 2024 and March 31, 2023, 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 and are reclassified into income as interest payments are made.

Table of Contents

In the first quarter of 2023, the Company entered into a series of interest rate swaps with a scheduled maturity of December 2025. The swaps have the effect of converting $300.0 million of the New Term Loan from a floating interest rate to a fixed interest rate and are classified as cash flow hedges. The fixed rates provided by these swaps, ranging from 4.16% to 4.21%, 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 March 31, 2024 and December 31, 2023, the total fair value of long-term debt and current maturities, excluding deferred financing costs, was $1,436.9 million and $1,394.5 million, respectively, compared with a carrying value of $1,472.1 million and $1,429.0 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.

(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 $95.8 million and $86.9 million at March 31, 2024 and December 31, 2023, respectively. The Company had advances on contracts totaling $36.2 million and $38.6 million at March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024, the Company recognized $10.7 million of revenue related to amounts previously included in advances on contracts. During the three months ended March 31, 2023, the Company recognized $11.6 million of revenue related to amounts previously included in advances on contracts.

At March 31, 2024, HE had remaining, fixed, unsatisfied performance obligations where the expected contract duration exceeds one year totaling $82.2 million. Of this amount, $21.8 million is expected to be fulfilled by March 31, 2025, $20.5 million by March 31, 2026, $15.0 million by March 31, 2027, $12.4 million by March 31, 2028 and the remainder thereafter. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year.

At March 31, 2024, Rail had remaining, fixed, unsatisfied performance obligations where the expected contract duration exceeds one year totaling $140.7 million. Of this amount, $53.4 million is expected to be fulfilled by March 31, 2025, $61.0 million by March 31, 2026, $22.6 million by March 31, 2027, and $3.7 million by March 31, 2028. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year.

The Rail Segment is currently manufacturing highly-engineered equipment under large long-term fixed-price contracts with SBB, Network Rail, and Deutsche Bahn. As previously disclosed, the Company recognized estimated forward loss provisions in 2022 and 2023 related to these contracts due to several factors, such as material and labor cost inflation, supply chain delays, the bankruptcy of a key vendor and increased engineering efforts. No provisions related to these contracts were recognized in three months ended March 31, 2024 and 2023.

Table of Contents

The estimated forward loss provisions represent the Company's best estimate based on currently available information. It is possible that the Company's overall estimate of liquidated damages, penalties and costs to complete these contracts may change, which could result in an additional estimated forward loss provision at such time that could be material. The Company will continue to update its estimates to complete these contracts, which will include the effect of negotiations with the customers regarding price increases, change orders and extensions to delivery schedules.

As of March 31, 2024, the contracts with Network Rail, Deutsche Bahn and the second contract with SBB are 59%, 43% and 88% complete, respectively based on costs incurred. The first contract with SBB has been completed.

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.

Executive Overview

The Company is a market-leading, global provider of environmental solutions for industrial, retail and medical waste streams. The name and brand identity of Enviri reflect the Company’s transformation over the past four years into an environmental solutions company that provides services to manage, recycle and beneficially reuse waste and byproduct materials across many industries. The Company has locations in approximately 30 countries, including the U.S. The Company was incorporated in 1956.

The Company's operations consist of three reportable segments: Harsco Environmental, Clean Earth and Harsco Rail. HE operates primarily under long-term contracts, providing critical environmental services and material processing to the global steel and metals industries, including zero waste solutions for manufacturing byproducts within the metals industry. CE provides specialty waste processing, treatment, recycling and beneficial reuse solutions for customers in the industrial, retail, healthcare and construction industries across a variety of waste needs, including hazardous, non-hazardous and contaminated soils and dredged materials. Rail is a provider of highly engineered maintenance equipment, after-market parts and safety and diagnostic systems and contracting solutions, which support railroad and transit customers worldwide.

The Company's Consolidated Financial Statements previously included the operating results of Rail as discontinued operations in the Consolidated Statements of Operations and the carrying value of the assets and liabilities of Rail were previously classified as Assets held-for-sale and Liabilities of assets held-for sale on the Consolidated Balance Sheets. However, since the sales process was paused and the held-for-sale criteria were no longer met as of March 31, 2024, Rail's operating results have been reclassified to continuing operations in the Consolidated Statements of Operations and its assets and liabilities have been reclassified to held-and-used in the Consolidated Balance Sheets for all periods presented.

The Company maintains a positive outlook across its businesses supported by favorable underlying growth characteristics in its businesses and investments by the Company to further supplement growth. The Company's view for 2024 and beyond is supported by the below factors, which should be considered in the context of other risks, trends and strategies in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

•HE: 2024 operating results are expected to be comparable with 2023 results, as positive impacts from higher service pricing, net of inflation, as well as operational improvement initiatives and higher environmental services demand at certain sites, including those linked to growth investments and new contracts, are expected to be offset by the impacts of lower commodity prices, the impact of foreign currency, a decrease in demand for downstream products, the sale of certain operating businesses, including Performix Metallurgical Additives, LLC, and potential site exits or closures. The global steel market has experienced a period of volatility in recent quarters due to the Russia-Ukraine conflict and the resulting energy crisis in Europe, as well as inventory management through the steel industry supply-chain and a change to the economic conditions due to rising interest rates. Underlying business conditions appear to have stabilized and these external factors are not anticipated to have a material impact on performance throughout the rest of the year. Over the longer term, the Company expects HE to grow as a result of economic growth that supports higher global steel consumption, as well as investments and innovation that support the environmental solutions needs of customers.

•CE: 2024 operating results are anticipated to improve, compared to 2023, as a result of higher services pricing, net of inflation, cost and operational improvements and an increase in environmental services demand across certain end-markets. These benefits will offset against certain favorable items, including the settlement of a pricing dispute with a customer, that occurred in 2023 and are not expected to repeat in 2024. Longer-term, the Company expects this segment to benefit from positive underlying market trends, supported by increased environmental regulation, further growth opportunities, lower-than-peer capital requirements and its attractive asset position, as well as from the less cyclical and more recurring nature of this business.

•Rail: 2024 operating results are expected to improve versus 2023, as a result of higher global demand for rail maintenance equipment, technology products and maintenance services. These benefits will be partially offset by lower contributions from after-market parts, resulting from lower volumes and a less favorable product mix. More broadly, Rail is supported by a strong backlog and the longer-term outlook for this business remains positive, supported by future infrastructure investments, economic development in emerging economies, rail electrification in certain geographies, safety awareness and automation.

Table of Contents

Selling, General and Administrative Expenses

SG&A for the three months ended March 31, 2024 increased $5.3 million, or 6.4%, from the three months ended March 31, 2023. The increase in the three months ended March 31, 2024 is due principally to higher compensation costs of $2.0 million, primarily contributed by Rail and CE, as well as a $2.0 million increase in professional fees, mainly incurred by CE.

Remeasurement of Long-Lived Assets

During the three months ended March 31, 2024, the Company recorded $10.7 million in depreciation and amortization expense for Rail's property, plant and equipment and intangible assets that were previously classified in Assets held-for-sale and have been reclassified into its respective caption for assets-held-for-use on the Company's Consolidated Balance Sheets. This amount includes all of the depreciation and amortization expense that would have been recognized during the periods that these assets were classified as held-for-sale.

(a) Includes $6.8 million net gain related to a lease modification that resulted in a lease incentive to the Company during the three months ended March 31, 2023 as discussed above in the HE segment results.

Interest Expense

Interest expense during the three months ended March 31, 2024 increased by $3.1 million, compared with the three months ended March 31, 2023. The increase during the three months ended March 31, 2024 is mainly driven by higher weighted average interest rates and increased borrowings from the Company's Senior Secured Credit Facilities, when compared to the three months ended March 31, 2023

Facility Fees and Debt-Related Income (Expense)

The Company recognized facility fee expense of $2.8 million and $2.4 million during the three months ended March 31, 2024 and 2023, respectively, of fees primarily related to the Company's AR Facility. See Note 9, Debt and Credit Agreements, in Part I, Item 1, Financial Statements.

Defined Benefit Pension Income (Expense)

Defined benefit pension expense for the three months ended March 31, 2024 and 2023 was $4.2 million and $5.3 million, respectively. This expense decrease is primarily related to a higher expected return on plan assets in the current year, compared to 2023 due to higher plan asset balances at December 31, 2023.

Income Tax Expense

Income tax expense from continuing operations for the three months ended March 31, 2024 and 2023 was $7.9 million and $8.0 million, respectively. The decrease in expense is primarily due to a decrease in disallowed interest expense during the three months ended March 31, 2024 and business improvement in various countries with no tax expense.

Income (Loss) from Continuing Operations

Loss from continuing operations was $15.7 million and $7.4 million for the three months ended March 31, 2024 and 2023, respectively. The primary drivers for this change are noted above.

Income (Loss) from Discontinued Operations

Losses from discontinued operations include incremental costs of $1.5 million and $1.7 million incurred during the three months ended March 31, 2024 and 2023, respectively, related to costs directly attributable to retained contingent liabilities of previously disposed businesses.

Table of Contents

Total Other Comprehensive Income (Loss)

Total other comprehensive loss was $7.7 million for the three months ended March 31, 2024, compared with total other comprehensive income of $7.2 million for the three months ended March 31, 2023. The primary driver of this change was the fluctuation of the U.S. dollar against certain currencies, inclusive of the impact of foreign currency translation of cumulative unrecognized actuarial losses on the Company's pension obligations.

Liquidity and Capital Resources

Cash Flow Summary

The Company currently expects to have sufficient financial liquidity and borrowing capacity to support the strategies within each of its businesses and its current operating and debt service needs. The Company currently expects operational and business needs to be met by cash provided by operations, supplemented with borrowings from time to time, principally under the Senior Secured Credit Facilities. The Company supplements the cash provided by operations with borrowings from time to time due to historical patterns of seasonal cash flow and the funding of various projects. The Company regularly assesses capital needs in the context of operational trends and strategic initiatives.

The Company’s cash flows from operating, investing and financing activities, as reflected on the Condensed Consolidated Statements of Cash Flows, are summarized in the following table:


	Three Months Ended
	March 31
(In millions)	2024		2023
Net cash provided (used) by:
Operating activities	$	1.3	$	36.9
Investing activities	(23.2)		(22.5)
Financing activities	12.9		(2.2)
Effect of exchange rate changes on cash and cash equivalents, including restricted cash	(8.3)		(1.1)
Net change in cash and cash equivalents, including restricted cash	$	(17.2)	$	11.1

Net cash (used) provided by operating activities — Net cash provided by operating activities in the first three months of 2024 was $1.3 million, a decrease in cash flows of $35.6 million from the first three months of 2023, primarily related to unfavorable changes in net working capital, including changes in accrued compensation, driven mainly by higher payments made for incentive compensation compared to the prior period, the timing of payments of accounts payable and changes in contract assets, partially offset by favorable changes from the timing of accounts receivable collections. This decrease is partially offset by higher year-to-date cash net income for the current year, when compared to the prior year, due to improved business performance.

Net cash used by investing activities — Net cash used by investing activities in the first three months of 2024 was $23.2 million, an increase of $0.7 million from the cash used during the first three months of 2023, which was related to an increase in purchases of capital expenditures, principally for HE. These purchases were offset by higher proceeds received from the sale of assets, principally for Corporate.

Net cash (used) provided by financing activities — Net cash provided by financing activities in the first three months of 2024 was $12.9 million, compared to net cash used by financing activities of $2.2 million the first three months of 2023. The change was primarily due to increased net borrowings of $21.4 million in the first three months of 2024, compared to net repayments of $1.2 million during the three months ended March 31, 2023. The proceeds from net borrowings during the 2024 were primarily used to support the Company's operating activities related to the changes in operating and investing activities described above. These cash inflows were partially offset by dividend payments of $8.2 million made to strategic venture partners for HE.

Effects of exchange rate changes on cash and cash equivalents, including restricted cash — The decrease as a result of these exchange rate fluctuations is due to the impact of the strengthening of the U.S. dollar against certain currencies, primarily from the Egyptian pound, during 2024 on the global cash balances held by the Company in these currencies.

Sources and Uses of Cash

The Company’s principal sources of liquidity are cash provided by operations on an annual basis and borrowings under the Senior Secured Credit Facilities, augmented by cash proceeds from asset sales. In addition, the Company has other bank credit facilities available throughout the world. The Company expects to continue to utilize all of these sources to meet future cash requirements for operations and growth initiatives.

Debt Covenants

At March 31, 2024, the Company was in compliance with these covenants, as the total net debt to Consolidated Adjusted EBITDA ratio was 4.08x and total interest coverage ratio was 3.06x. Based on balances and covenants in effect at March 31, 2024, the Company could increase net debt by $392.7 million and remain in compliance with these debt covenants. Alternatively, Consolidated Adjusted EBITDA could decrease by $33.7 million or interest expense could increase by $12.3 million and the Company would remain in compliance with these covenants at March 31, 2024. 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, higher than forecasted interest rate increases, the timing of working capital, including the collection of receivables, or an inability to successfully realize increased pricing and to implement cost reduction initiatives that mitigate the impacts of inflation and other factors that may adversely impact its realized operating margins.

AR Facility

The Company maintains a revolving trade receivables securitization facility to accelerate cash flows from trade accounts receivable. Under the AR Facility, the Company and its designated subsidiaries continuously sell their trade receivables as they are originated to the wholly-owned bankruptcy-remote SPE. The SPE transfers ownership and control of qualifying receivables to PNC up to a maximum purchase commitment of $150.0 million. No proceeds were received from the AR Facility during the three months ended March 31, 2024.

Cash Management

The Company has various cash management systems throughout the world that centralize cash in various bank accounts where it is economically justifiable and legally permissible to do so. These centralized cash balances are then redeployed to other operations to reduce short-term borrowings and to finance working capital needs or capital expenditures. Due to the transitory nature of cash balances, they are normally invested in bank deposits that can be withdrawn at will or in very liquid short-term bank time deposits and government obligations. The Company's policy is to use the largest banks in the various countries in which the Company operates. The Company monitors the creditworthiness of banks and, when appropriate, will adjust banking operations to reduce or eliminate exposure to less creditworthy banks.

Table of Contents

At March 31, 2024, the Company's consolidated cash and cash equivalents included $102.0 million held by non-U.S. subsidiaries and approximately 10.4% of the Company's consolidated cash and cash equivalents had regulatory restrictions that would preclude the transfer of funds with and among subsidiaries. Non-U.S. subsidiaries also held $26.0 million of cash and cash equivalents in consolidated strategic ventures. The strategic venture agreements may require strategic venture partner approval to transfer funds with and among subsidiaries. While the Company's remaining non-U.S. cash and cash equivalents can be transferred with and among subsidiaries, the majority of these non-U.S. cash balances will be used to support the ongoing working capital needs and continued growth of the Company's non-U.S. operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2023 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2023 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 Annual Report on Form 10-K for the year ended December 31, 2023. 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. Liquidity The Company’s cash flow forecasts, combined with existing cash and cash equivalents and borrowings available under the Senior Secured Credit Facilities, indicate sufficient liquidity to fund the Company’s operations for at least the next twelve months. As such, the Company’s unaudited Consolidated Financial Statements have been prepared on the basis that it will continue as a going concern for a period extending beyond twelve months from the date the unaudited Consolidated Financial Statements are issued. This assessment includes the expected ability to meet required financial covenants and the continued ability to draw down on the Senior Secured Credit Facilities (see Note 9, Debt and Credit Agreements). Reclassifications During the three months ended March 31, 2024, the Company determined that the held-for-sale criteria for Rail was no longer met and, as a result, the Company made reclassifications to prior year amounts previously classified as discontinued operations and assets held-for-sale in the Company's Consolidated Statements of Operations and Consolidated Balance Sheets, along with the accompanying notes to the Company's Consolidated Financial Statements. See Note 3, Discontinued Operations and Dispositions for further details.

Accounting Changes and Error Corrections [Abstract]
Recently Adopted and Recently Issued Accounting Standards	Recently Adopted and Recently Issued Accounting Standards The Company has not adopted any accounting standards during the first quarter in 2024: The following accounting standards have been issued and become effective for the Company at a future date: In November 2023, the FASB issued changes that require expansion of annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2024. The Company is currently evaluating the impact that this change will have on the Company's disclosures. In December 2023, the FASB issued changes which require greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2025. 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.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	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 three months ended March 31, 2024, the Company determined that there were no events or indicators present that would indicate that it was more-likely-than-not that its reporting units' fair values were less than their carrying amounts, which would require a further interim impairment analysis. However, unfavorable economic conditions, including continued cost inflation and labor shortages, as well as rising interest rates, 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 any of the Company's reporting units in a future period.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense from continuing operations for the three months ended March 31, 2024 and 2023 was $7.9 million and $8.0 million, respectively. The decrease in expense for the three months ended March 31, 2024, compared with the three months ended March 31, 2023, is primarily due to a decrease in disallowed interest expense and business improvement in various countries with no tax expense. For the three months ended March 31, 2024, the Company calculated its quarterly tax provision based on its best estimate of the full year tax rate applicable to the quarter. For the three months ended March 31, 2023, due to the insignificant amount of pre-tax book loss relative to the size of permanent book-tax differences and a varying net income (loss) pattern projected for the year, the Company’s tax provision estimate was determined using an actual year-to-date method. The reserve for uncertain tax positions on March 31, 2024 and December 31, 2023 was $3.4 million, including interest and penalties. Within the next twelve months, it is reasonably possible that $0.6 million in unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2023 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2023 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 Annual Report on Form 10-K for the year ended December 31, 2023. 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.
Liquidity	Liquidity The Company’s cash flow forecasts, combined with existing cash and cash equivalents and borrowings available under the Senior Secured Credit Facilities, indicate sufficient liquidity to fund the Company’s operations for at least the next twelve months. As such, the Company’s unaudited Consolidated Financial Statements have been prepared on the basis that it will continue as a going concern for a period extending beyond twelve months from the date the unaudited Consolidated Financial Statements are issued. This assessment includes the expected ability to meet required financial covenants and the continued ability to draw down on the Senior Secured Credit Facilities (see Note 9, Debt and Credit Agreements).
Reclassifications	Reclassifications During the three months ended March 31, 2024, the Company determined that the held-for-sale criteria for Rail was no longer met and, as a result, the Company made reclassifications to prior year amounts previously classified as discontinued operations and assets held-for-sale in the Company's Consolidated Statements of Operations and Consolidated Balance Sheets, along with the accompanying notes to the Company's Consolidated Financial Statements. See Note 3, Discontinued Operations and Dispositions for further details.
Recently Adopted and Recently Issued Accounting Standards	Recently Adopted and Recently Issued Accounting Standards The Company has not adopted any accounting standards during the first quarter in 2024: The following accounting standards have been issued and become effective for the Company at a future date: In November 2023, the FASB issued changes that require expansion of annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2024. The Company is currently evaluating the impact that this change will have on the Company's disclosures. In December 2023, the FASB issued changes which require greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. The changes become effective starting with the Company's annual financial statements for the year ended December 31, 2025. 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.
