**EXPLANATORY NOTE**

Enviri Corporation ("Enviri," the "Company," "we," "our," or "us") is filing this Amendment No. 1 on Form 10-K/A (this "Amendment") to amend the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the "SEC") on February 24, 2026 (the "Original Form 10-K"), to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted in reliance on General Instruction G(3) to Form 10-K, which provides that registrants may incorporate by reference certain information from a definitive proxy statement filed with the SEC within 120 days after the end of the fiscal year. The Company is filing this Amendment because a definitive proxy statement containing such information will not be filed by the Company within 120 days after the end of the fiscal year covered by the Original Form 10-K.

Pursuant to Rule 12b-25 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 are being filed as exhibits to this Amendment under Item 15 of Part IV. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. The cover page of the Original Form 10-K is also amended to update the number of shares of the Company's common stock outstanding and to delete the reference to the incorporation by reference of the Company's definitive proxy statement.

Except as described above, no other changes have been made to the Original Form 10-K, and this Amendment does not modify, amend, or update in any way any of the financial or other information contained in the Original Form 10-K. This Amendment does not reflect events occurring after the date of the filing of the Original Form 10-K in any way other than as required to reflect the amendments discussed above and reflected below. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and with our filings with the SEC made subsequent to the filing of the Original Form 10-K. Any defined terms used and not otherwise defined herein are as defined in the Original Form 10-K.

**Advisory Vote on Named Executive Officer Compensation**

At our 2025 Annual Meeting, approximately 94% of the votes cast were in support of our executive compensation proposal. The Board and the MD&C Committee viewed this strong support as an indicator of general approval of our approach to executive compensation.

We continue to engage our stockholders on various issues through ongoing stockholder engagement. During these engagement meetings, stockholders have an opportunity to provide feedback on a variety of topics, including executive compensation. The MD&C Committee will continue to consider stockholders' viewpoints in the development and approval of all compensation policies and practices at Enviri.

**Executive Summary with 2025 Compensation Highlights**

Our executive compensation program's primary objective is aligning our executives' pay with the interests of our stockholders. The program is also designed to reward short- and long-term financial, strategic, and operational business results, while facilitating the Company's need to attract, motivate, develop, and retain highly qualified executives who are critical to our long-term success.

**Target Total Direct Compensation**

• Base salary increases effective January 1, 2025, ranged between 0% and 5%.

• There were no changes to Annual Incentive Plan ("AIP") or Long-Term Incentive Plan ("LTIP") target award opportunities for the current NEOs, except for Mr. Hochman due to his appointment as Enviri's President and Chief Operating Officer.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

**AIP Design and Payouts**

• The MD&C Committee retained its approach to determining AIP awards using a balanced scorecard focused on two key areas: financial goals (80%) and non-financial goals (20%).

• For 2025, the MD&C Committee approved changes to the financial metric by replacing the Business Unit Contribution with two distinct performance metrics: Adjusted EBITDA and Adjusted Free Cash Flow ("Adjusted FCF"). This change enhances NEO accountability by sharpening the focus on profitable growth, operational efficiency, and disciplined capital management.

• Preset non-financial goals for 2025 are based on strategic efforts deemed critical to the Company's success for the NEOs, except for Mr. Beswick. Mr. Beswick's non-financial goals are a mix of strategic (10%) and ESG goals (10%).

• Based on the Company's financial and non-financial performance against the pre-determined measures under the AIP, awards ranged between 56.6% and 100.80% of target opportunity.

For further details, please refer to the "2025 AIP Awards" section below.

**LTIP Payouts (PSUs) for the 2023-2025 Performance Period**

• Enviri's Total Stockholder Return ("TSR") performance relative to the S&P 600 Industrials Index was at the 84th percentile.

• As a result, the NEOs earned 200% of the PSUs granted in 2023.

For further details, please refer to the "2025 LITP" section below.

**Compensation Guiding Principles**

The following principles guide the MD&C Committee's design of Enviri's executive compensation program. These principles reflect Enviri's belief that well-structured compensation programs are essential to drive performance, support strategic objectives, and align with stockholder interests.

---

| | |
|:---|:---|
| **Guiding Principles** | **How Enviri Employed Them** |
| **Promote a Performance-Oriented Environment** | • Ensured that employees had a clear line-of-sight between their actions, business results, and alignment to stockholder value creation;<br>• Provided greater rewards to individuals and teams who most positively impacted the success of the business; and<br>• Differentiated compensation to retain high-performing and high-potential talent and attract high-caliber talent. |
| **Provide Market-Competitive Rewards** | • Regularly monitored market practices and trends in industries where Enviri competed for talent;<br>• Structured the program to target the median of relevant markets for talent; and<br>• Considered realized pay outcomes relating to Enviri's stock performance and business results. |
| **Allow Flexibility within a Common Framework** | • Created a program with a common global strategy and framework; and<br>• Allowed flexibility to accommodate the unique talent and compensation needs of Enviri's diverse businesses, workforce, and global markets. |
| **Adhere to a Clear Governance Model** | • Employed appropriate oversight and controls to govern design and administration; and<br>• Clearly defined the roles and responsibilities of all program stakeholders. |
| **Be Well Communicated** | • Specified the objectives, design, and value of each component of fixed and variable compensation within the context of total rewards; and<br>• Used multiple sources of communication to help ensure the link between pay and performance was well understood by key participants and stakeholders. |

---

***Talent Management Strategy***

Integral to these guiding principles was Enviri's talent management strategy, developed by management and overseen by the MD&C Committee and the Board. Achieving Enviri's strategic goals and delivering long-term stockholder value requires a consistent focus on attracting, developing and retaining a high-performing senior leadership team.

Each year, including 2025, Enviri conducts a comprehensive talent review to assess the organizational capabilities necessary to execute its strategy, evaluate executive team performance, and identify succession depth and retention risks for key leadership roles. The MD&C Committee and the Board provide feedback on these assessments, and directors were regularly involved in the selection and evaluation of executive officers.

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

***Elements of Enviri's 2025 NEO Compensation Program***

Enviri's executive compensation program is designed primarily to align executive pay outcomes with the interests of Enviri's stockholders. The program is designed to reward achievement of short- and long-term financial, strategic, and operational objectives, while supporting Enviri's ability to attract, motivate, develop, and retain highly qualified executives critical to its long-term success. The key elements of the Enviri 2025 NEO compensation program were as follows:

---

| | |
|:---|:---|
| **Element** | &nbsp;&nbsp;**Description** |
| **Base Salary** | &nbsp;&nbsp;&nbsp;&nbsp;• Annual fixed source of income based on competitive market data. |
| **Annual Incentive Plan ("AIP Awards")** | &nbsp;&nbsp;&nbsp;&nbsp;• Variable, performance-based annual cash payment linked to, and focused on, financial and strategic goals.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Business unit non-financial objectives, including ESG goals. |
| **Long-Term Incentive ("LTIP Awards")** | &nbsp;&nbsp;&nbsp;&nbsp;• Variable, performance and time-based annual awards comprised of a mix of equity vehicles, including performance share units ("PSUs"), restricted stock units ("RSUs"), and stock appreciation rights ("SARs").<br>&nbsp;&nbsp;&nbsp;&nbsp;• Realizable compensation based upon Enviri's stock price performance and total stockholder return ("TSR"). |

---

***Target Total Direct Compensation Mix***

For 2025, the MD&C Committee designed Enviri's executive compensation program to emphasize performance-based pay over fixed compensation. A substantial majority of each NEO's target total direct compensation was variable and, therefore, "at risk" and dependent on the achievement of annual and long-term performance goals under Enviri's annual incentive plan and long-term incentive plan, with 66.9% of the CEO's target total direct compensation at risk and an average of 54.2% of target total direct compensation at risk for the other NEOs. This mix reflects the MD&C Committee's belief that a significant portion of executive pay should be directly aligned with company performance and stockholder value creation.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

**Program Governance and Oversight** 

The MD&C Committee maintains a disciplined approach to executive compensation governance, emphasizing transparency, independence, and alignment with stockholder interests. The MD&C Committee ties a significant portion of executive pay to performance and used both financial and strategic measures to determine incentive outcomes.

---

| | |
|:---|:---|
| **WHAT ENVIRI DOES** | **WHAT ENVIRI DOESN'T DO** |
| • Tie a substantial portion of executive pay to performance.<br>• Maintain stock ownership guidelines for executives and directors.<br>• Apply a "double-trigger" standard for change-in-control severance.<br>• Maintain a clawback policy consistent with SEC and New York Stock Exchange ("NYSE") requirements.<br>• Use an independent compensation consultant reporting directly to the MD&C Committee.<br>• Conduct annual risk assessments of incentive programs.<br>• PSUs earned above target only when Enviri's TSR is positive. | • Provide tax gross-ups or single-trigger severance benefits.<br>• Reprice stock options or SARs.<br>• Pay dividends or dividend equivalents on unearned performance awards.<br>• Permit hedging or pledging of Enviri stock; nor short sales.<br>• Offer employment agreements with guaranteed compensation.<br>• Provide excessive perquisites or other non-performance-based benefits. |

---

**Compensation Decision-Making Framework**

***General Process***

The MD&C Committee determined 2025 compensation for the NEOs in accordance with its established annual process. In making these determinations, the MD&C Committee reviewed Enviri's overall performance, market conditions, and individual executive contributions. The MD&C Committee also considered:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The achievement of financial performance objectives, including Adjusted EBITDA and Adjusted FCF;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Progress towards key strategic, operation, and ESG initiatives within each NEO's scope of responsibility; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Market competitive compensation levels reflected in survey data and peer group data.

***Roles***

*MD&C Committee* 

All members of the MD&C Committee were independent directors under applicable NYSE listing standards. The MD&C Committee oversaw the design and administration of Enviri's 2025 NEO compensation program, approved the compensation of the CEO, and reviewed and approved compensation recommendations for the other NEOs.

*Chairman & CEO* 

Our Chairman & CEO, Mr. Grasberger, assisted by our Human Resources department, administered the executive compensation program as delegated by the MD&C Committee. Mr. Grasberger met with the MD&C Committee and, in collaboration with the independent compensation consultant, made recommendations related to the overall structure of our NEO compensation program, set and evaluated 2025 AIP metrics, including the non-financial measures, and made specific recommendations regarding the form and amount of compensation opportunities for the other NEOs.

Final decisions regarding NEO compensation are always made by the MD&C Committee, and the Chairman & CEO did not play any role with respect to his own compensation.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

*Independent Compensation Consultant* 

The MD&C Committee retained Pearl Meyer & Partners, LLP ("Pearl Meyer") as its independent compensation consultant for 2025. Pearl Meyer advised the MD&C Committee on market practices, peer group composition, and program design and attended meetings at the MD&C Committee's request. The MD&C Committee evaluated Pearl Meyer's independence in accordance with NYSE listing standards and Rule 10C-1 of the Exchange Act and determined that the engagement raised no conflicts of interest.

*Management Consultants* 

Our Human Resources department retained Willis Towers Watson ("WTW") during 2025 to provide additional executive compensation support. Our Human Resources department also used various survey data compiled by WTW to provide information to the MD&C Committee as part of its decision-making processes.

In 2025, WTW also provided pension plan-related and other similar advice to our Human Resources and Finance departments as well as measurement support for various casualty exposures. The decision to engage WTW for the services unrelated to Enviri's executive compensation program was made by Enviri's management.

**How We Used Market Data for 2025 Pay Decisions** 

In establishing 2025 compensation levels for the NEOs, the MD&C Committee sought to align executive pay opportunities with competitive market levels for comparable roles. With the assistance of its independent compensation consultant, Pearl Meyer, the MD&C Committee reviewed two primary sources of information: broad-based compensation survey data and a defined group of publicly traded peer companies. The MD&C Committee generally targeted total direct compensation for NEOs at or near the market median (50th percentile) and exercised discretion to adjust individual pay levels to reflect each executive's experience, performance, and scope of responsibility.

---

| | |
|:---|:---|
| **Item** | **Key Details, Processes and Decisions** |
| **Survey Data** | • Selected surveys focused on capital goods, industrial manufacturing, diversified metals and minerals, environmental services, and commodity-based companies reflecting similar revenue size to Enviri.<br>• The MD&C Committee did not materially rely upon data from any individual company participating in any of the surveys in making compensation decisions. |
| **Compensation Peer Group** | • Compensation data obtained from SEC filings helped the MD&C Committee understand the pay levels in industries in which Enviri competed for talent.<br>• Focused on elements of compensation (base salary, annual bonus, and long-term incentives) for executives at companies with comparable revenues, industry focus, enterprise value, number of employees, global (multi-national) footprint, market capitalization, and other similar business-related factors. |

---

The MD&C Committee applies judgment in setting final compensation opportunities, which could vary above or below the market median based on individual performance, specialized expertise, or other business considerations.

**2025 Compensation Peer Group** 

For 2025, the MD&C Committee reviewed the composition of Enviri's compensation peer group to confirm that it continued to reflect companies comparable to Enviri in terms of industry, scale, and operational complexity. With input from Pearl Meyer, the MD&C Committee selected peer companies that generally meet the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Diversified industrial organizations, including companies in these primary industries: Environmental & Facilities Services and related companies as well as Industrial Machinery, Specialty Chemical, Construction Machinery and Heavy Trucks and Metals & Minerals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Global (multi-national) footprint, number of employees, operating in many individual locations with approximately 30% or more of total revenues deriving from outside the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Asset or capital intensive nature or long-term contract service providers;

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Diversified industrial organizations, including companies in these primary industries: Environmental & Facilities Services and related companies as well as Industrial Machinery, Specialty Chemical, Construction Machinery and Heavy Trucks and Metals & Minerals; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Companies with revenues and other financial characteristics—such as enterprise value, market capitalization, operating income, and net income—generally ranging from approximately one-half to two-and-a-half times the size of Enviri.

The MD&C Committee periodically reviewed the compensation peer group to confirm that it remained aligned with Enviri's business profile, and the parameters described above. For 2025, the MD&C Committee, with input from Enviri management and Pearl Meyer, approved the removal of two prior peers—Evoqua Water Technologies Corp. and Heritage-Crystal Clean, Inc.—primarily due to merger and acquisition activity, and the addition of one company—Casella Waste Systems, Inc.—to maintain overall comparability. Although other companies compete with Enviri's business segments, certain potential peers were excluded because their size, scope, or operations differed materially from Enviri's. The following companies comprised Enviri's 2025 compensation peer group ("Enviri's 2025 Compensation Peer Group"):

---

| | |
|:---|:---|
| **2025 Enviri Compensation Peer Group** | **2025 Enviri Compensation Peer Group** |
| • ATI Inc.<br>• Astec Industries Inc.<br>• BrightView Holdings, Inc.<br>• Casella Waste Systems, Inc.<br>• CECO Environmental Corp.<br>• Clean Harbors, Inc.<br>• Commercial Metals Company | • Ecovyst Inc.<br>• EnPro Industries, Inc.<br>• GFL Environmental Inc.<br>• Gibraltar Industries, Inc.<br>• Minerals Technologies Inc.<br>• Montrose Environmental Group, Inc.<br>• Stericycle, Inc. |

**2025 Enviri Compensation Decision Details**

The MD&C Committee considered competitive market data, internal equity, and individual performance when determining 2025 compensation levels for the NEOs. With input from Pearl Meyer, the MD&C Committee reviewed compensation information from Enviri's 2025 Compensation Peer Group and relevant survey sources. Target total direct compensation opportunities were generally positioned near the market median, with adjustments based on the scope of responsibilities, experience, and performance.

The MD&C Committee exercised judgment to ensure that total compensation remained competitive and aligned with Enviri's performance and stockholder interests.

**2025 Executive Compensation Program**

***Base Salary***

Base salary represents the fixed portion of total compensation and is designed to provide a stable source of income and support the attraction and retention of executive talent. For 2025, the MD&C Committee established base-salary levels for the NEOs based on market data from Enviri's 2025 Compensation Peer Group and relevant survey sources, as well as individual experience, scope of responsibility, and performance.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

***2025 AIP Awards***

The NEOs were eligible to participate in the 2025 AIP ("2025 AIP"), which provided the opportunity to earn performance-based cash awards based on the achievement of pre-established financial and strategic objectives. The 2025 AIP was designed to align incentive opportunities with the achievement of Enviri's near-term operating and financial commitments, support profitable growth and operational efficiency, emphasize disciplined and effective use of capital, incorporate widely recognized financial performance metrics to enhance transparency, and include strategic and ESG objectives that advanced Enviri's long-term value creation goals.

For 2025, the MD&C Committee approved a 2025 AIP design that placed greater emphasis on financial performance and operational discipline. Under the 2025 AIP, Adjusted EBITDA and Adjusted FCF together accounted for 80% of the overall award opportunity, reflecting Enviri's focus on profitability and cash generation. The remaining 20% of the award was based on strategic and ESG objectives. The MD&C Committee retained discretion to reduce final payouts as appropriate based on overall performance and other relevant factors.

*2025 AIP Award Opportunity* 

Target annual incentive opportunities under the 2025 AIP were expressed as a percentage of base salary, with potential payouts ranging from 0% to 200% of the target award amount. Target opportunities were established by the MD&C Committee based on each NEO's level of responsibility, scope of influence on Enviri's results, and a review of relevant market benchmarking data. For 2025, there were no changes to target annual incentive opportunities for any NEOs. The weighting of financial and non-financial performance goals for each NEO is presented in the table below.

*2025 AIP Metrics Summary* 

The financial metrics under the 2025 AIP for the NEOs (other than Mr. Beswick) consisted of Enviri Consolidated Adjusted EBITDA and Enviri Consolidated Adjusted FCF, which together represented 80% of the total award opportunity. The remaining 20% of the total award opportunity was based on non-financial metrics related to strategic initiatives supporting Enviri's enterprise priorities.

Mr. Beswick, as Senior Vice President and President of Clean Earth, had the majority of his 2025 AIP award opportunity based on his business segment's Adjusted EBITDA and Adjusted FCF. The remaining portion of his award opportunity was based on Clean Earth strategic goals (10% weighting) and ESG objectives (10% weighting)

The following table summarizes the financial and non-financial metrics used to determine 2025 AIP opportunities for the NEOs:

(1)Adjusted EBITDA is a non-GAAP financial measure and consists of income (loss) from continuing operations adjusted to add back income tax expense; equity income of unconsolidated entities, net; net interest expense; defined benefit pension income (expense); facility fees and debt-related income (expense); and depreciation and amortization (excluding amortization of deferred financing costs); and excludes unusual items. Segment Adjusted EBITDA consists of operating income from continuing operations adjusted to exclude unusual items and add back depreciation and amortization (excluding amortization of deferred financing costs).

(2)Adjusted FCF is a non-GAAP financial measure and consists of net cash provided (used) by operating activities less capital expenditures and expenditures for intangible assets; plus capital expenditures for strategic ventures, total proceeds from sales of assets, and certain transaction-related / debt-refinancing expenditures. It is important to note that Adjusted FCF does not represent the total residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements and settlements of foreign currency forward exchange contracts, are not deducted from this measure.

*Financial Metrics: Performance Range*

For 2025, the MD&C Committee established the following threshold, target, and maximum performance levels based on the 2025 AOP approved by the Board and supported by sensitivity analyses around earnings and cash-flow assumptions. These levels were intended to align management accountability with Enviri's focus on profitability, cash generation, and disciplined capital deployment.

(1)Payouts are interpolated between each specific performance level using a non-linear payout schedule.

Enviri's consolidated financial goals were designed to promote accountability for enterprise-wide results, and the business segment goals aligned incentive opportunities with the financial measures most directly influenced by segment leadership. In establishing the 2025 targets, the MD&C Committee considered 7% year-on-year EBITDA growth (excluding business divestitures and foreign exchange impacts) and positive Free Cash Flow. In determining the 2025 EBITDA target, we reviewed planned growth for 2025, the prior year's financial performance, anticipated impact of investments, expected benefits from key initiatives and improvements and actions to strengthen cash flow and asset performance as well as the outlook for key end-markets for each business segment. These considerations informed the calibration of threshold, target, and maximum performance levels for 2025.

*Non-Financial Goals and Performance Range* 

The 2025 strategic and ESG goals were established at the beginning of the year using an approach consistent with that applied to the financial performance goals. These goals were approved by the MD&C Committee to focus senior management on near-term objectives that supported Enviri's long-range business and sustainability priorities. Payouts on the non-financial goals portion of the 2025 AIP award could range from 0% to 200% of target, based on the MD&C Committee's assessment of performance against the established objectives. The MD&C Committee reviewed progress toward achievement of these goals on a regular basis throughout the year.

*2025 AIP Results*

Following the completion of fiscal 2025, the MD&C Committee reviewed the performance against the approved financial and non-financial goals under the 2025 AIP and certified the results in accordance with the plan's terms. Based on this review, MD&C Committee approved final AIP awards for the NEOs.

For the financial portion of the award (80% weighting), payouts were determined using the performance ranges established at the beginning of the year for Adjusted EBITDA, net of nonrecurring, unusual items determined by the MD&C Committee and Adjusted FCF. Payout earned for Enviri's Adjusted EBITDA was 61%, while no payout was earned for Adjusted FCF. For the non-financial portion (20% weighting), the MD&C Committee assessed achievement of the strategic and ESG objectives approved at the start of 2025. See the table below for the assessment and the outcomes of the 2025 non-financial measures. In both cases, the MD&C Committee applied the terms of the plan and its discretion to reduce (but not increase) awards as appropriate based on overall performance and other relevant factors.

Mr. Beswick's calculation was based on 20% Adjusted Enviri EBITDA, plus 40% Clean Earth Business Adjusted EBITDA, plus 20% Clean Earth Business Adjusted FCF, plus 10% Clean Earth Business Strategic goals, plus 10% Clean Earth Business ESG goals resulting in a combined payout factor of 100.8%.

***Enviri Long-Term Incentive Plan Awards***

For 2025, the MD&C Committee approved LTIP awards designed to align the interests of executives with those of Enviri stockholders and to promote long-term value creation. The program provided a mix of performance-based and time-based equity awards to balance pay for performance with retention objectives. The MD&C Committee determined this mix based on market practices, individual roles, and Enviri's overall compensation framework. LTIP awards are intended to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Link executive compensation to the creation of sustained stockholder value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Support meaningful stock ownership in accordance with Enviri's stock ownership guidelines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Encourage cross-functional leadership and collaboration; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Promote retention of key executives whose performance is critical to Enviri's long-term success.

*Setting 2025 LTIP Award Opportunities* 

For the 2025 LTIP award cycle, the MD&C Committee and the Board established target award levels for each NEO as a percentage of base salary. In determining these targets, the MD&C Committee considered each NEO's level of responsibility, scope of influence on Enviri's results, and relevant market benchmarking data. Target award levels were designed to position total direct compensation within a competitive range of market median levels for similar roles, while

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

recognizing that the realized value of LTIP awards will depend on Enviri's future stock price performance and total stockholder return.

The following table summarizes the long-term incentive target award levels approved by the MD&C Committee for 2025.

|:---|:---|
| **Executive** | **FY'25 Target**<br>**LTIP Award**<br>**Level As a**<br>**Percentage of**<br>**Base Salary** |

*2025 LTIP Award Mix*

For 2025, the MD&C Committee approved the LTIP structure consisting of PSUs, RSUs, and SARs. The mix of award types was intended to balance performance-based and service-based incentives, support alignment with stockholder interests, and promote executive retention.

The 2025 LTIP award mix for the CEO consisted of 50% PSUs, 25% RSUs, and 25% SARs. For the other NEOs, awards were allocated equally across the three vehicles (approximately one-third each).

PSUs link compensation directly to Enviri's long-term stockholder value creation by tying vesting to Enviri's TSR performance relative to the S&P 600 Industrials Index (the "Index"). The 2025 PSU performance period covers January 1, 2025, through December 31, 2027. TSR is calculated based on the 90-day average stock price prior to the beginning of the performance period and the 90-day average stock price at the end of the performance period, with dividends assumed to have been reinvested on the ex-dividend date. PSU awards are settled either in shares of Enviri common stock or cash following the MD&C Committee's certification of results, and participants receive accumulated dividend equivalents on any earned shares. Payouts are capped at 100% of target if Enviri's TSR is negative over the three-year performance period. The number of shares earned is determined based on Enviri's relative TSR percentile ranking, as shown below (achievement will be interpolated between the various performance points on the table):

---

| | | |
|:---|:---|:---|
| **Performance Level** | **Index Percentile<br>Achievement** | **Payout as a % of<br>Target** |
| Maximum | 75<sup>th</sup> | 200% |
| Target | 50<sup>th</sup> | 100% |
| Threshold | 25<sup>th</sup> | 25% |
| Below Threshold | Below 25<sup>th</sup> | 0% |

---

RSUs provide a retention-focused component of long-term compensation and vest ratably in equal annual installments over a three-year period, subject to continued employment. Vesting of RSUs reinforces alignment with stockholder interests by tying executive value to Enviri's long-term stock performance.

SARs provide value only to the extent that Enviri's stock price appreciates following the grant date. SARs generally vest in one-third increments over a three-year period and have a ten-year term from the grant date. The exercise price for each SAR is equal to the closing price of Enviri common stock on the grant date, ensuring that executives realize value only when stockholders experience positive returns.

*Vesting of 2023 PSUs* 

PSUs granted in 2023 vested based on Enviri's TSR performance relative to the Index over the three-year performance period ending December 31, 2025. The program measured Enviri's TSR using the 30-day average stock price at the beginning and end of the performance period, with dividends assumed to have been reinvested on the ex-dividend date.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

Enviri's TSR performance for the period ranked at the 84th percentile of the Index, which resulted in a payout of 200% of the units granted in 2023.

*Accelerated Vesting of 2024 and 2025 PSUs for Certain NEOs* 

In December 2025, in order to mitigate the negative effects of the transactions contemplated by the Merger Agreement and the Separation Agreement, under Section 280G of the Internal Revenue Code of 1986, as amended (the "Code") on Enviri and its employees, including the NEOs identified in the table below, the MD&C Committee determined that it was appropriate to accelerate vesting of certain PSUs granted in 2024 and 2025. Enviri conditioned this accelerated vesting on each NEO executing an agreement providing the following protections (the "Clawback Agreements"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the Merger Agreement is terminated in accordance with its terms without the transactions being consummated, the NEO will be required to repay to Enviri or its successor a "recoupment amount" equal to the excess of the fair market value of the number of shares of Enviri's common stock subject to the accelerated PSUs over the fair market value of the shares subject to the number of the PSUs that the NEO would have earned in the ordinary course (or in connection with a different corporate transaction), in each case, measured as of the applicable vesting event. This recoupment amount would also be reduced by Enviri to account for taxes paid by the NEO as a result of the accelerated vesting and any other amounts Enviri determines to be appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the NEO's employment with Enviri is terminated (a) by the NEO or (b) by Enviri for cause, in either case, prior to consummation of the transactions contemplated in the Merger Agreement and the Separation Agreement, the NEO will be required to repay to Enviri or its successor a recoupment amount equal to the fair market value of the number of shares of Enviri's common stock equal to the number of accelerated PSUs, measured as of December 17, 2025. This recoupment amount would also be reduced by Enviri to account for taxes paid by the NEO as a result of the accelerated vesting and any other amounts Enviri determines to be appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The NEO is required to comply with the terms of a restrictive covenant agreement attached to the Clawback Agreement. If the NEO fails to comply with the restrictive covenants, the NEO will be required to repay to Enviri or its successor an amount equal to the fair market value of the number of shares of Enviri's common stock equal to the number of accelerated PSUs, measured as of December 17, 2025, less taxes paid by the NEO as a result of the accelerated vesting, and may also be subject to further legal and equitable remedies available to Enviri.

The MD&C Committee determined that it was appropriate to accelerate vesting and settlement of the PSUs granted in 2024 and 2025 at a payout level of 200% of the target number of PSUs in order to mitigate the negative effects of the transactions contemplated in the Merger Agreement and the Separation Agreement under Section 280G of the Code, as reflected in the table below.

**Other Enviri Compensation Elements**

During 2025, the NEOs participated in the same broad-based employee benefit programs generally available to Enviri's U.S. employees, including health insurance, disability insurance, and participation in Enviri's 401(k) plan. In addition, term life insurance benefits equal to two times base salary, up to a maximum of $800,000, were provided to each NEO. The NEOs were also eligible to participate in the Non-Qualified Retirement Savings and Investment Plan – Deferred Compensation Plan ("NQ RSIP"), which supplements the Retirement Savings and Investment Plan ("RSIP") with respect to 401(k) contributions that could not be made because of limitations under the Code.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

Enviri provides limited perquisites and personal benefits to the NEOs that are consistent with those available to employees in comparable positions at similar sized companies. The values of these perquisites and benefits are reflected in the "All Other Compensation" column of the 2025 Summary Compensation Table and detailed in the accompanying All Other Compensation Table. See "—2025 Summary Compensation Table" and "—All Other Compensation."

**Retirement Plans**

*RSIP*. Under the RSIP, Enviri makes matching contributions equal to 100% of the employees' contributions on the first 3% of compensation and 50% on the next 2% of compensation. The RSIP also provides for a discretionary contribution, determined annually by Enviri, to the account of each eligible employee who remains an active participant as of December 31 of the plan year.

*NQ RSIP*. Under the NQ RSIP, Enviri provides the matching and discretionary contributions, if any, that would otherwise be made to the participants' RSIP accounts in respect of their contributions but for limitations imposed by the Code. Enviri's contributions to the NQ RSIP are made in the form of credits of non-qualified deferred compensation to bookkeeping accounts maintained as a record of the benefits to which employees are entitled.

**Employment Agreements with NEOs** 

Enviri is not a party to any employment agreements with its NEOs.

**Potential Payments upon Change in Control and Other Termination Events**

Enviri currently maintains change-in-control severance arrangements for its NEOs that provide severance benefits in connection with a qualifying termination of employment following a change in control or material divestment. Additional information regarding Enviri's existing arrangements appears under "—Potential Payments upon Termination or Change in Control" below.

**Stock Ownership Guidelines**

In 2025, we continued to maintain stock ownership guidelines that applied to the NEOs. Our stock ownership guidelines encourage the retention of stock acquired through our LTIP awards. The stock ownership guidelines are established as a multiple of each NEO's base salary and were benchmarked against the stock ownership guidelines for similarly situated executives at peer group companies. They were also based on the Board's determination of appropriate share ownership levels based on our compensation system. Under the guidelines, each NEO is encouraged to own a specific amount of our common stock and is restricted from selling shares until the guideline has been satisfied.

Our NEOs have five years from the date they are first granted LTIP awards to comply with the guidelines. If a NEO is promoted into a position with greater ownership requirements, that individual has five additional years to comply with the new guidelines. All common stock held by the NEOs, whether acquired because of an LTIP award or otherwise, is included in determining whether they have achieved the applicable ownership guideline. Unvested stock options, unvested PSUs, and unvested SARs are not included in calculating whether the guidelines have been met. Failure to meet the guidelines within the applicable five-year period will result in a review by the MD&C Committee to determine the cause of such failure and to develop an appropriate corrective action plan.

All NEO's have met their ownership guidelines as of December 31, 2025.

**Right to Recover Incentive Compensation** 

Consistent with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), and the NYSE Listed Company Manual, the Board has adopted a policy (a "clawback policy") providing for the Company to recover (or "claw back") from certain current and former key employees any wrongfully earned performance-based compensation, including stock-based awards, if the Company is required to prepare an accounting restatement of any of the Company's financial statements due to the Company's material noncompliance with any financial reporting requirement under U.S. securities laws, subject to certain limited exceptions permitted by applicable law or listing standards. Such claw back may be implemented by a number of available methods, as set forth in the Company's policy and as determined by the MD&C Committee.

Consistent with the Dodd-Frank Act, the Company's Insider Trading Policy prohibits all Board members and employees, including corporate officers, from engaging in any transaction in which they may profit from short-term speculative swings in the value of the Company securities (or "hedging"). For this purpose, "hedging" includes "short-sales" (selling borrowed securities which the seller hopes can be purchased at a lower price in the future) or "short sales against the box" (selling owned, but not delivered securities), "put" and "call" options (publicly available rights to sell or buy securities within a certain period of time at a specified price or the like), and other hedging transactions designed to minimize the risk inherent in owning common stock, such as zero-cost collars and forward sales contracts.

Our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and any applicable NYSE listing standards, and expressly prohibits Board members and employees from purchasing or selling our securities while in possession of material, non-public information, or otherwise using such information for their personal benefit.

Additionally, Board members and executives are prohibited from pledging shares as collateral for a loan or in a margin account.

**Policy Regarding Tax and Accounting Impact on Executive Compensation** 

The MD&C Committee annually reviews and considers the deductibility of the compensation paid to our executive officers, which includes each of the NEOs. Under the Tax Cuts and Jobs Act of 2017, the exemption for qualifying performance-based compensation was repealed for taxable years beginning after December 31, 2017. As a result, compensation paid to our executive officers (on or after January 1, 2018) in excess of $1 million is generally not deductible unless it qualifies for certain transition relief. While the Company will monitor guidance and developments in this area, the MD&C Committee believes that its primary responsibility is to provide a compensation program that attracts, retains, and rewards the executive talent necessary for our success. Consequently, the MD&C Committee may pay or provide compensation that is not tax deductible or is otherwise limited as to tax deductible.

**Compensation Policies and Practices as They Relate to Risk Management** 

In 2025, Pearl Meyer and senior management reviewed our compensation policies and practices for all employees. They concluded, and the MD&C Committee concurred, that any risks arising from our compensation policies and practices are not reasonably likely to have a material adverse impact on the Company. In addition, we reviewed the relationship between our risk management policies and practices and the incentive compensation we provide to our NEOs and other key employees to confirm that our incentive compensation does not encourage unnecessary and excessive risk taking. The findings of these reviews indicated that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our compensation program provides a balance between our short-term and long-term goals and objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Under our compensation program, the highest amount of compensation can be achieved through consistent superior performance over sustained periods of time, which discourages short-term risk taking;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incentive awards are capped by the MD&C Committee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stock ownership guidelines, the clawback policy, and prohibition on hedging mitigate excessive risk taking.

Furthermore, as described above, compensation decisions may include the subjective use of negative discretion, which has the ability to restrain the influence of formulae or objective factors on excessive risk taking.

**Compensation Committee Report** 

The MD&C Committee has reviewed and discussed the CD&A, set forth above, with management. Based on this review and discussion, the MD&C Committee recommended to the Board that the CD&A be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

(1)Amounts are not reported for 2023 and 2024 if the executive was not a NEO in that year.

(2)Mr. Vadaketh received a hiring bonus of $720,000 upon hire, of which $500,000 was payable within 30 days of his start date of October 16, 2023, and $220,000 was payable six months after his start date with Enviri. Mr. Beswick received a hiring bonus of $150,000 paid upon starting his employment with Enviri. Ms. Kozak received a hiring bonus of $110,000 upon hire, of which $25,000 was paid in 2022 and $85,000 was payable within 30 days after the one-year service anniversary of February 28, 2022.

(3)The amounts in this column reflect the aggregate grant date fair values (computed in accordance with Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 718) of the RSU and PSU portion of the LTIP awards for 2023, 2024 and 2025. The actual value, if any, realized by each NEO for these awards is a function of the value of the underlying shares if and when these awards vest and, for the PSUs, the level of attainment of the applicable performance goals. The above information does not reflect an estimate for forfeitures.

(4)The amounts for the PSUs granted in 2025 reflect a Monte-Carlo simulation that considers the probable outcome of the performance conditions as of the grant date, consistent with the estimate of aggregate compensation cost to be recognized over the service period determined as of the grant date under FASB ASC Topic 718. For these amounts, see the "Grant Date Fair Value of Stock and SAR/Option Awards" column of the "2025 Grants of

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

Plan-Based Awards" table below. The following are the values of the 2025 PSUs as of the grant date assuming attainment of the maximum level of achievement: Mr. Grasberger, $4,655,053; Mr. Vadaketh, $1,325,876; Mr. Hochman, $734,177; Mr. Beswick, $634,828 and Ms. Kozak, $450,121.

(5)See Note 14, "Stock-Based Compensation," to Enviri's audited financial statements included elsewhere in this information statement for additional information and for a discussion of the assumptions used to calculate share-based compensation expense under FASB ASC Topic 718.

(6)The amounts shown in this column for 2025 represent the grant date fair value (computed in accordance with FASB ASC Topic 718) for the SAR portion of the 2025 LTIP awards. These amounts may not represent actual compensation that will be realized by the NEOs with respect to these awards, but instead represent the grant date fair value of the awards for accounting purposes, as required to be shown in this table by SEC rules. In order for each NEO to realize any value upon exercise of the SARs, the market price of Enviri's common stock must be above $6.03 per share on the applicable exercise date for grants issued on March 4, 2025. Any amounts that may become payable to the NEOs with respect to these awards are also subject to the service-based vesting criteria described above under the heading "Enviri Long-Term Incentive Plan Awards" above.

(7)The amounts shown in this column reflect the actual 2025 AIP award payout (if any) for each NEO, as applicable, as approved by the MD&C Committee based on the achievement of the pre-determined financial and non-financial goals as further described in the "Compensation Discussion and Analysis" above.

(8)None of the US-based NEOs are covered under the Enviri Employees Pension Plan.

(9)Mr. Hochman received a salary increase effective November 20, 2025, due to his promotion to President and Chief Operating Officer. His new salary is $750,000. 2025 salary reported reflects actual salary paid throughout the year.

(1)These columns reflect 2025 AIP award opportunities for the NEOs. AIP awards were made pursuant to the 2013 Equity and Incentive Compensation Plan, as amended (the "2013 Plan"), and are described more fully in the section titled "2025 AIP Awards" above. Target estimated payouts are based on the NEO's annual base salary rate multiplied by their target AIP percent pro-rated for their hire date or change in role. Threshold amounts represent approximately 50% of the full target values, the target is 100% of the full target values and maximum amounts represent 200% of full target values. Actual 2025 AIP payouts are disclosed in the "Non-Equity Incentive Plan Compensation" column of the 2025 Summary Compensation Table.

(2)These columns reflect the range of 2025 PSU award opportunities. Threshold amounts represent approximately 25% of target values, the target is 100% of the full target value, and maximum amounts represent 200% of target values. For information on the performance vesting conditions applicable to the 2025 PSUs, see the description under the heading "Enviri Long-Term Incentive Plan Awards" above.

(3)This column reflects the RSU component of the 2025 LTIP awards granted to the NEOs under the 2013 Plan and is described more fully under the heading "Enviri Long-Term Incentive Plan Awards" above. These RSUs will generally vest ratably on the first three anniversaries of the grant date. The value reflects the RSU's grant date fair value as of March 4, 2025 (computed in accordance with FASB ASC Topic 718) of $6.03 for all NEOs.

(4)This column reflects the SAR component of the 2025 LTIP awards granted to the NEOs, under the 2013 Plan and is described more fully under the heading "Enviri Long-Term Incentive Plan Awards" above. These SARs will generally vest ratably over three years and expire 10 years from the date of grant. On March 4, 2025, SARs were granted with a strike price of $6.03, Enviri's grant date stock price, to all NEOs.

(2)On December 31, 2025, the PSUs granted in 2023 with vesting conditioned on Enviri's TSR performance relative to the Index for the three-year period from 2023 through 2025 ended. Enviri's TSR for the period was at the 84th percentile of the Index, resulting in a 200% payout.

(3)On December 15, 2025, the MD&C Committee approved accelerated vesting of certain 2024 and 2025 PSUs, as further described in the "Accelerated Vesting of 2024 and 2025 PSUs for Certain NEOs" above. The details of this vesting event are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Mr. Grasberger's accelerated stock awards included two PSU grants: (i) 432,920 stock-settled PSUs (granted March 11, 2024) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout); and (ii) 630,766 PSUs (granted March 4, 2025) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout) and consisting of 50% stock-settled PSUs (315,384) and 50% cash-settled PSUs (315,382). No stock was issued in settlement of the cash-settled PSU; thus, only the realized value was reported.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Mr. Vadaketh's accelerated stock award included 127,034 stock-settled PSUs (granted March 11, 2024) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Mr. Hochman's accelerated stock award included 70,682 stock-settled PSUs (granted March 11, 2024) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Mr. Beswick's accelerated stock awards included two PSU grants: (i) 50,204 stock-settled PSUs (granted March 11, 2024) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout); and (ii) 86,020 PSUs (granted March 4, 2025) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout) and consisting of 50% stock-settled PSUs (43,010) and 50% cash-settled PSUs (43,010). No stock was issued in settlement of the cash-settled PSU; thus, only the realized value was reported.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Ms. Kozak's accelerated stock awards included two PSU grants: (i) 43,334 stock-settled PSUs (granted March 11, 2024) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout); and (ii) 60,992 PSUs (granted March 4, 2025) that vested on December 17, 2025, at a fair market value of $17.85 (representing a 200% performance payout) and consisting of 50% stock-settled PSUs (30,496) and 50% cash-settled PSUs (30,496). No stock was issued in settlement of the cash-settled PSU; thus, only the realized value was reported.

(4)For the RSUs, PSUs and SARs, the gross value realized on vesting was calculated using the fair market value based on the closing stock prices of Enviri's common stock on the respective vesting dates.

(5)Ms. Kozak exercised 10,100 SARs during 2025 corresponding to the March 7, 2023 grant. The value realized at the time of the exercise was calculated by multiplying the number of SARs upon exercise by the difference between the stock price of Enviri's common stock at the time of the transaction (10,100 times $18.22) and the closing price of Enviri's Common Stock on the date of the grant ($7.45 grant date fair value).

(1)This column reflects amounts contributed by us to the bookkeeping account maintained for each applicable NEO under the NQ RSIP. The NQ RSIP is an unfunded plan, and contributions are made in the form of credits of non-qualified deferred compensation to bookkeeping accounts maintained as a record of the benefits to which participants are entitled. The amounts reported in this column are reported as compensation for 2025 in the 2025 Summary Compensation Table under the "All Other Compensation" column.

(2)Aggregate earnings/(losses) in 2025 include (a) earnings/(losses) on the bookkeeping account maintained for the applicable NEO under the NQ RSIP, credited at the same rates of return as those applicable to the investment fund(s) selected by the NEO under the RSIP; and (b) as applicable, dividend equivalents credited to the portion of each applicable NEOs' bookkeeping account, if any, deemed to be invested in the Enviri Corporation Stock fund under the NQ RSIP. The investment options available under the NQ RSIP are substantially consistent with those available under the RSIP. Because there were no preferential earnings/(losses) on deferred compensation during the year ended December 31, 2025, none of the amounts reported in this column are reported as compensation for 2025 in the Summary Compensation Table.

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

(3)Amounts reflect the value of the bookkeeping account maintained for each applicable NEO under the NQ RSIP, determined based on the value of the investment fund(s) to which such account is deemed to be allocated. The following amounts are included in the fiscal year-end balance and, for NEOs that were included in the fiscal 2024 proxy disclosure, were previously reported in the 2024 Summary Compensation Table as compensation: Mr. Grasberger, $71,399; Mr. Vadaketh, $26,773; Mr. Hochman, $32,360; Mr. Beswick, $23,287; and Ms. Kozak, $20,323. The year-end aggregate balance for the NEOs as reported on the 2024 proxy disclosure, which are included in 2024 aggregate balance, were as follows: Mr. Grasberger, $854,333; Mr. Vadaketh, $40,435; Mr. Hochman, $294,645; Mr. Beswick, $23,828; and Ms. Kozak, $33,428.

**Potential Payments Upon Termination or Change in Control** 

Enviri entered into agreements with and maintained plans that require compensation to be paid to certain NEOs in the event of a termination of employment, including as the result of a change in control.

Set forth below are tables, one for each NEO, depicting payment obligations following the potential termination of the NEO's employment with Enviri, including as the result of a change in control. The amounts disclosed below in each table are estimates only and do not necessarily reflect the actual amounts that would be paid to the NEOs, which would only be known at the time that they become eligible for payment and, in the case of payments related to a change in control, would only be payable if a change in control were to occur. The tables reflect the amounts that would be payable under various change in control arrangements assuming that the termination event occurred on December 31, 2025.

(1)Pursuant to the terms of each RSU and SAR award agreement, RSUs and SARs granted to the NEOs immediately vest and become non-forfeitable upon the executive's death, disability or retirement on or after the specified retirement age (age 62) plus five years of service. RSUs and SARs granted to the NEOs under the 2013 Plan immediately vest and become non-forfeitable upon the executive's qualifying termination following a change in control (as defined in the 2013 Plan) or a material divestment (as defined in the CIC Agreements, defined below).

(2)In accordance with the terms of the amended and restated change in control severance agreements entered into by and between us and certain of the NEOs (each, a "CIC Agreement"), Messrs. Grasberger, Vadaketh, Hochman and Beswick and Ms. Kozak, will each be entitled to the payments described below if such executive's employment is terminated by us or by them under the circumstances described below during the 180 days prior,

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

or the two-year period after, the date on which a "change in control" or a "material divestment" occurs (which we refer to as the "Protection Period"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Termination due to death or disability (as defined in the CIC Agreement): the CIC Agreement will terminate without further obligations other than those accrued or earned and vested (if applicable) as of the date of termination, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the executive's full base salary through the date of termination at the rate in effect on the date of termination or, if higher, at the highest rate in effect at any time from the 90-day period preceding the effective date of the change in control through the date of termination (the "Highest Base Salary");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a pro-rata target annual incentive compensation payment for the year of termination; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any compensation previously deferred by the executive (together with any accrued interest) and not yet paid by us and any accrued vacation pay not yet paid by us (we refer to the amounts in these three sub-bullets as the "Accrued Obligations").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Termination for "cause" (as defined in the CIC Agreement): the CIC Agreement will terminate without further obligations other than the obligation to pay to the executive the Highest Base Salary through the date of termination plus the amount of any compensation previously deferred by the executive (together with any accrued interest) and not yet paid by us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Termination by the executive other than for "good reason" (as defined in the CIC Agreement), including by reason of retirement: the CIC Agreement will terminate without further obligations other than those accrued or earned and vested (if applicable) through the date of termination, including the executive's base salary through the date of termination at the rate in effect on the date of termination plus the amount of any compensation previously deferred by the executive (together with any accrued interest) and not yet paid by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Termination by us (other than for "cause," death or disability) or termination by the executive for "good reason": we shall pay the executive the aggregate of the following amounts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the executive's full base salary and vacation pay accrued through the date of termination at the rate in effect on the date of termination plus pro-rated annual incentive compensation through the date of termination at the same percentage rate applicable to the calendar year immediately prior to the year in which the date of termination occurs, plus all other amounts to which the executive is entitled under any of the compensation plans, programs, practices or policies in effect at the time such payments are due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any compensation previously deferred by the executive (together with any accrued interest) and not yet paid by us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a lump sum severance payment in an amount equal to a multiple of the executive's Highest Base Salary and target annual incentive compensation in effect for the year in which the date of termination occurs. The multiple is three times base salary and target incentive compensation in the case of Mr. Grasberger, and two times base salary and target incentive compensation in the case of Messrs. Vadaketh, Hochman and Beswick and Ms. Kozak; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any unvested outstanding awards granted under the 2013 Plan, subject to the change in control rules contained in the 2013 Plan and each applicable award agreement.

The payments described above and shown in the individual tables below may be subject to reduction to avoid the imposition of golden parachute excise taxes in certain cases. No downward adjustments have been estimated or reflected in the individual tables below. No NEO is entitled to a gross-up payment to offset any golden parachute excise taxes or related taxes that may be owed as a result of the NEO's receipt of compensation from the Company.

The individual tables below set forth the present value of lump sum payments for Accrued Obligations and the other payments described above based on 2025 salaries and 2025 target annual incentive compensation, assuming the triggering event occurred on December 31, 2025 during a Protection Period.

(3)The individual tables below set forth the present value of the lump sum payments for each executive officer assuming (a) the executive officer was terminated for cause or voluntarily on December 31, 2025 and (b) that such termination took place either prior to a change in control or following the Protection Period (as defined above and as applicable to the NEO). In the case of a voluntary termination, both qualified pension plan and supplemental executive retirement plan benefits are payable.

(4)The individual tables below set forth the present value of the lump sum payments for each executive officer assuming (a) the executive officer was terminated involuntarily without cause on December 31, 2025 and (b) that such termination took place either prior to a change in control or following the Protection Period (as defined above and as applicable to the NEO).

(5)The individual tables below set forth the present value of the lump sum payments for each executive officer assuming (a) the executive's death or disability occurred on December 31, 2025 and (b) that such death or disability took place either prior to a change in control or following the Protection Period (as defined above and as applicable to the NEO).

(6)Life insurance proceeds are payable only in the event of the executive's death (not disability).

(7)The individual tables below set forth the present value of the lump sum payments for each executive officer assuming (a) the executive officer retired on December 31, 2025 and (b) that such retirement took place either prior to a change in control or following the Protection Period (as defined above and as applicable to the NEO).

(1)If Ms. Kozak were terminated during the Protection Period for cause, she would receive the payment shown for termination as a result of cause in a non-change in control scenario.

(2)The amounts payable to Ms. Kozak due to her death or disability during the Protection Period would match the amounts payable to her for such occurrences outside of the Protection Period.

(3)Assumes all non-equity incentive plan compensation earned for 2025, as disclosed in the "Non-Equity Incentive Plan Compensation" column of the 2025 Summary Compensation Table, has been earned as of December 31, 2025, and thus is not additional compensation resulting from the termination scenarios described in this table.

(4)Vesting of Ms. Kozak's RSUs and SARs granted under the 2013 Plan would accelerate (i) in the event of a qualifying termination following a change in control or material divestment; (ii) in the event of her death or disability; or (iii) in the event of her retirement. No amounts are included under the "Retirement" column for Ms. Kozak because she is not currently retirement eligible. SARs value was calculated as the in-the-money amount as of December 31, 2025 (Enviri's December 31, 2025 stock price ($17.92) minus the per-share strike price times the unvested SARs).

**CEO Pay Ratio Disclosure** 

Pursuant to Section 953(b) of the Dodd-Frank Act, the SEC issued the "Pay Ratio" disclosure rule under Item 402(u) of Regulation S-K requiring registrants to disclose the ratio of annual total compensation for their Principal Executive Officer to that of the employee identified as the registrant's median compensated individual.

It was determined that the 2025 annual total compensation of the individual identified as Enviri's median compensated individual (excluding the CEO) was $56,850, the annual total compensation of Mr. Grasberger was $5,972,813 and the ratio between the two was 105:1.

This pay ratio was a reasonable estimate calculated in a manner consistent with SEC rules utilizing the payroll and employment records and the methodology described below. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

***Methodology for Selecting the Median Employee***

The SEC rules permit a company to use the same median employee identified in the second year of the required three-year recalculation period if there are not changes that would significantly affect the pay ratio disclosure. Enviri did not engage in any significant acquisition or divestiture activity that would significantly affect this pay ratio disclosure. As a result, the methodology to select the median employee was as follows:

October 1, 2024 was selected as the determination date and used foreign exchange rates effective on September 30, 2024. The five percent (5%) "de minimis" allowance was applied to exclude the following country from the employee population totaling 4.86%:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Egypt: 579 employees or 4.86% of 11,908

The total population used for the "de minimis" exception prior to these exclusions is 11,908, with 3,793 being U.S. based employees, and 8,115 being non-U.S. employees. After applying the five percent (5%) "de minimis" exclusion, the total population was 11,329.

In selecting the median employee, a valid statistical sampling approach was utilized to identify a cluster of employees within 10% of the median, using a consistently applied compensation measure of annual base pay. To determine annual base pay for the hourly and part-time employee population, a reasonable set of assumptions was used to calculate the actual hours worked. From the cluster of employees at or near the median, a median employee was selected that best represented Enviri's overall employee population.

***Putting the Ratio in Context***

As discussed above, pay and benefits were targeted at competitive levels based on the job duties and location of the employee.

Enviri's workforce was global with employees located in over 30 countries around the world. The international employee footprint was driven by client needs, with most employees working at client sites outside of the United States. As such, when interpreting the pay ratio results, it is important to keep in mind that pay practices vary by country based on client contract terms, local statutory requirements, cost of living and applicable local market competitive pay practices.

Lastly, total compensation for executive officers was comprised of a significant portion that varied based on financial and Enviri stock price performance. Eighty-two-point-nine percent (82.9%) of the CEO's total pay varied with performance while the majority of pay of the median employee, seventy-three percent (73%) was fixed base salary and overtime. The equity portion of the CEO's pay used in the pay ratio calculation reflected his "opportunity" and the actual value of these awards varied based on stock price and performance.

**Recovery Analysis under our Clawback Policy**

We disclosed in our Annual Report on Form 10-K filed with the SEC on February 24, 2026, that, in accordance with the applicable accounting guidance, we revised prior period financial statements after identifying a longstanding accounting error and determining that correcting the error in the current period would be material to our fiscal 2025 results. The error related to the defined benefit pension obligation associated with our U.K. pension plan. We included revised financial statements in the Form 10-K that corrected this error as well as other unrelated previously identified immaterial errors. As noted in the Form 10-K, the error correction disclosed was a restatement that required a recovery analysis under our clawback policy.

As a result, we conducted a recovery analysis of all incentive-based compensation received by covered officers during the past three completed fiscal years to ascertain whether any adjustments or recoupments were required as a result of the restatement. The recovery analysis concluded that no adjustments or recoupments were required because the restatement did not impact any of the financial reporting measures used to determine the incentive-based compensation received by the covered officers during this period.

**Non-Employee Director Compensation** 

It is the general policy of our Board that compensation for non-employee directors should be competitive with similarly situated companies and should be comprised of a mix of cash and equity. Our Governance Committee annually reviews market data regarding comparable director compensation programs. This data is prepared by management and the independent compensation consultant utilizing several broad board compensation studies completed within one year of the Governance Committee's review.

The compensation structure for non-employee directors in 2025 was as follows:

---

| | |
|:---|:---|
| **Enviri Non-Employee Director Compensation Element** | **2025 Program<br>Value** |
| Annual Retainer: | $85000 |
| Lead Director Retainer (Annual):<sup>(1)</sup> | $45000 |
| Audit Committee Chair Retainer (Annual):<sup>(2)</sup> | $17500 |
| Audit Committee Member Retainer (Annual): | $10000 |
| MD&C Committee Chair Retainer (Annual):<sup>(2)</sup> | $17500 |
| MD&C Committee Member Retainer (Annual): | $10000 |
| Governance Committee Chair Retainer (Annual):<sup>(2)</sup> | $17500 |
| Governance Committee Member Retainer (Annual): | $10000 |
| Board of Directors and Committee Meeting Fee (Per Meeting):<sup>(3)</sup> |  |
| Other Meetings (Per Meeting):<sup>(3)</sup> |  |
| Telephonic Board of Directors Meeting Fee (Per Meeting):<sup>(3)</sup> |  |
| Telephonic Committee Meeting Fee (Per Meeting):<sup>(3)</sup> |  |
| Restricted Stock Unit Grant Value (Annual): | $130000 |
| Plan Participation: | Deferred Compensation Plan |

---

(1)The lead director retainer was paid in addition to the annual retainer.

(2)Committee chair retainers were paid in lieu of, not in addition to, committee member retainers.

(3)For each board of directors or applicable committee meeting held in a given year in excess of twice the number of regularly scheduled meetings established at the beginning of such year, the non-employee directors received a per meeting fee equal to $1,500 (for in-person/telephonic board of director meetings and in-person committee meetings) or $750 (for telephonic committee meetings).

In addition to the above-listed compensation, our directors were reimbursed for reasonable travel expenses related to attendance at Board or committee meetings.

Our Board has instituted a stockholding requirement for directors equal to five times the annual retainer. Each director has five years from the date of joining the Board to comply with the stockholding requirement. Vested and unvested RSUs, as well as phantom shares acquired through deferral of director fees (as described below), were included for purposes of determining compliance with our director stockholding requirements. On December 31, 2025, all of Enviri's continuing non-employee directors who had served for at least five years were in compliance with our director stockholding requirements.

Beginning in 2016, RSUs were granted under the Enviri 2016 Non-Employee Directors' Long-Term Equity Compensation Plan (the "Director Plan"). Each RSU under the Director Plan vested at the close of business on the earlier of (i) the first anniversary of the grant date or (ii) the annual meeting of stockholders in the year immediately following the year of grant, subject to accelerated vesting in full if service as an Enviri director terminated due to death, disability, or under a mandatory retirement policy, and subject to pro rata vesting in the event of termination of service in other circumstances. Beginning in 2025, each RSU vested on the first anniversary of the grant date. Each RSU will be settled by issuance of a share of Enviri common stock. Dividend equivalents on the RSUs are not paid prior to vesting, but are settled thereafter.

The Deferred Compensation Plan for Non-Employee Directors allows each non-employee director to defer all or a portion of his or her director compensation, including RSU grants, until some future date selected by the director. Pursuant to the director's election, the accumulated deferred compensation is held in either an interest-bearing account or a Company phantom share account. The interest-bearing deferred account accumulates notional interest on the account balance at a rate

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

equal to the five-year United States Treasury Note yield rate in effect from time to time. Contributions to the phantom share account are recorded as notional shares of the Company's Common Stock. Deferred amounts are credited to the director's account quarterly on the 15th of February, May, August, and November. The number of phantom shares recorded is equal to the number of shares of our common stock that the deferred compensation would have purchased at the market price of the stock on the day the account is credited. Dividend equivalents are earned on the phantom shares and are credited to the account as additional phantom shares. All phantom shares are non-voting and, effective as of February 18, 2026, payments out of the account are made in shares of common stock. Under certain circumstances, the accounts may be paid out early upon termination of directorship following a change in control.

Directors who are actively employed by us receive no additional compensation for serving as directors, and we do not pay consulting or professional service fees to active directors.

**Item 13.&nbsp;&nbsp;&nbsp;&nbsp;Certain Relationships and Related Transactions, and Director Independence.**

***Policies and Procedures Regarding Transactions with Related Persons***

For the fiscal year ended December 31, 2025, there were no transactions with the Company in which any related person had a direct or indirect material interest that would be required to be disclosed pursuant to Item 404 of Regulation S-K, nor were any such transactions planned.

Our policies and procedures regarding related person transactions are set forth in writing in the Governance Committee Charter and in our Code of Conduct. As set forth in its charter, the Governance Committee is generally responsible for reviewing and approving all material transactions with any related person. Related persons include any of our directors, director nominees or executive officers and certain of our stockholders, and their immediate family members. Copies of the Governance Committee's Charter and our Code of Conduct are available at the Corporate Governance section of our website at www.enviri.com/corporate-governance. Approval of related person transactions by our full Board may also be warranted under certain circumstances (for example, to allow for approval of a related person transaction by a majority of disinterested directors).

To identify related person transactions, each year we submit and require our directors and officers to complete Directors' and Officers' Questionnaires identifying any and all transactions with us in which the officer or director (or their family members) has an interest. We review related person transactions due to the potential for a conflict of interest. A conflict of interest occurs when an individual's private interest interferes, or appears to interfere, in any way with our interests. We

------

<u>[**Table of Contents**](#i2f6bffc1577949dbbd1258b6f05f4e1a_10)</u>

expect our directors, officers and employees to act and make decisions that are in our best interests and encourage them to avoid situations which could present a conflict between our interests and their own personal interests.

Our directors, officers and employees are prohibited from using their position of employment or other relationship with us to influence decisions concerning business transactions between us and a company in which they or a member of their immediate family has a personal interest through ownership, with the exception of investments in publicly-held corporations when the investment results in less than a 1% ownership interest. In addition, directors, officers and employees must not accept personal favors or benefits from those dealing with us that could influence or could give the impression of influencing their business judgment. Our Code of Conduct, which applies to each of our directors, officers and employees, sets forth our expectations regarding potential and actual conflicts of interest. The section of the Code of Conduct entitled "Ethical Business Practices" covers the concept of conflicts of interest and our view about when an inappropriate undertaking may be occurring.

***Director Independence***

The Board has affirmatively determined that the following seven directors are independent pursuant to the applicable independence requirements set forth in the NYSE Rules and by the SEC because they either have no relationship with the Company (other than as a director and stockholder) or because any relationship they have with the Company is immaterial: Messrs. Earl, Fanandakis, Laurion, Purvis, and Quinn, and Mses. Haznedar and O'Mara. In making these independence determinations, the Board, in consultation with the Governance Committee, reviewed the direct and indirect relationships between each director and the Company and its subsidiaries, as well as the compensation and other payments each director received from or made to the Company and its subsidiaries.

**Item 14.&nbsp;&nbsp;&nbsp;&nbsp;Principal Accountant Fees and Services.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Includes fees related to the integrated audit of the consolidated financial statements and internal controls over financial reporting as well as statutory audits and quarterly reviews.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Includes fees related to agreed-upon procedures.

The Audit Committee has considered the possible effect of non-audit services on the auditors' independence and pre-approved the type of non-audit services that were rendered. The Audit Committee has adopted a policy authorizing the pre-approval of certain audit, non-audit and tax services (and related fees) to be provided by the independent auditors. The services to be provided are to be reviewed with the Audit Committee and approval is given for a specific dollar amount and for a period of not greater than 12 months. Services that are not pre-approved in this manner must be pre-approved on a case-by-case basis throughout the year. Additionally, if the pre-approved fee is exceeded, the Audit Committee must be advised of such overruns. In making its decision regarding the approval of services, the Audit Committee will consider whether such services are consistent with the SEC's rules on auditor independence, whether the independent auditor is best positioned to provide such services and whether the services might enhance the Company's ability to manage or control risk or improve audit quality. No services were provided during the last two fiscal years pursuant to the de minimis safe harbor exception from the pre-approval requirements.

All of the fees included in the table above were pre-approved by the Audit Committee.
