THIS SEPARATION AGREEMENT AND GENERAL RELEASE (the “Agreement”) is entered into by and between Harsco Corporation (the “Company”) and David Stanton (“Employee”).

WHEREAS, Employee has been employed by the Company as a Senior Vice President and Group President – Harsco Clean Earth; and

WHEREAS, Employee and the Company wish to end their employment relationship on mutually agreeable terms as set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements and covenants hereinafter set forth, and intending to be legally bound, the parties agree as follows:

1. Separation of Employment. Employee’s employment with the Company ended on May 5, 2022 (the “Separation Date”), after which he will not report to work or accept any assignment or task on behalf of the Company other than to perform the obligations as expressly set forth herein. The Company shall pay Employee the regular base pay to which Employee is entitled through the Separation Date pursuant to regular payroll practices. To the extent that Employee has any accrued but unused vacation, personal and/or sick time through the Separation Date, payment for all such accrued but unused vacation, personal and/or sick time is included in the payments set forth in Paragraph 2 of this Agreement. The foregoing described payments are subject to all applicable taxes and withholdings.

2. Payments to Employee. In exchange for Employee entering into, not revoking and fully complying with the terms of this Agreement (including, but not limited to, the post-employment obligations set forth herein), the Company will pay Employee’s base salary for the period May 6, 2022 through December 31, 2022 (the “Severance Payment”) as set forth below. Subject to Employee’s continued compliance with the terms of this Agreement, the aggregate amount of the Severance Payment will be paid in four equal quarterly installments in the gross amount of Eighty Eight Thousand Eight Hundred Ninety One Dollars and No Cents ($88,891.00) for each quarterly installment. The quarterly installments will be paid in the first full pay period after each of the following dates: July 1, 2022, October 1, 2022, January 1, 2023, and April 1, 2023. The Severance Payment and is subject to all applicable taxes and withholdings.

(b) After the Separation Date, Employee will become eligible to elect continuation of health care coverage under the Consolidated Omnibus Budget Reconciliation Act of 1986 (“COBRA”), as amended, with information regarding continuation rights provided in separate correspondence. If Employee elects to enter into this Agreement and makes a timely election of COBRA for Employee and his eligible spouse and dependents, then the Company agrees to pay the Employee’s health insurance COBRA premium for the Employee, his spouse and covered dependents in the amount of One Thousand Five Hundred Ninety Six Dollars and Sixty Six Cents ($1,596.66) for the seven (7) month period of June 2022 through December 2022 and/or reimburse Employee for any direct payment of COBRA premiums during such period, within fifteen (15) calendar days of submission of reasonable proof of payment; provided that, Employee elects COBRA continuation coverage within forty five (45) calendar days after the Separation Date and continues to comply with the terms of this Agreement. To the extent Employee elects COBRA continuation coverage later than forty five (45) calendar days after the Separation Date, Employee will remain eligible to elect and receive COBRA continuation coverage subject to and in accordance with the terms and conditions of COBRA; however, the Company will not reimburse or pay any portion of Employee’s COBRA premiums, Employee will be responsible for the entire cost of such COBRA continuation coverage, and will be so responsible for the remainder of the COBRA continuation period. Employee’s period of COBRA coverage will not be extended by the time-period, if any, during which the Company pays the cost of Employee’s continuation of coverage. The Company’s obligation, pursuant to this section, to pay COBRA premiums on behalf of Employee, shall cease at such time that Employee fails to comply with the terms of this Agreement and/or secures comparable health insurance coverage from another source, including coverage from the employer of Employee’s spouse. Employee agrees to promptly notify the Company in writing upon obtaining other health insurance coverage. In the event of Employee’s death prior to December 31, 2022, the Company agrees to continue to pay the COBRA health insurance premiums for the Employee’s spouse and covered dependents through December 2022. Employee understands and agrees that the Company reserves the right to amend or terminate its health insurance plans at any time.

(c) Nothing in this Agreement shall affect any rights that Employee may have under the Company’s retirement plans. If applicable, Employee may make appropriate election for distribution or payment of benefits, if any, from these plans according to their respective provisions.

(d) Employee may elect to convert any group life insurance coverage to an individual program within thirty (30) days of the Separation Date at the rates provided by the carrier, with conversion information provided in separate correspondence; provided that, notwithstanding anything to the contrary herein, in the event of such election, Employee shall be solely responsible for all premiums and costs associated with such coverage.

(e) The Severance Payment and the payments set forth in Paragraph Nos. 2 and 3(b) above shall be referred to collectively as the “Consideration Payments” in this Agreement.

(f) The Company will not take any action to contest Employee’s receipt of unemployment compensation benefits in connection with the termination of Employee’s employment; provided, however, that it is mutually understood that the Company shall respond truthfully to any inquiries from the state unemployment compensation authorities (i.e., the Company will indicate that Employee was involuntarily terminated for business reasons and not for willful misconduct) and unemployment compensation eligibility decisions are made by the state unemployment compensation authorities.

(g) No Other Payment. Employee acknowledges that the Company has no prior legal obligation to provide the Consideration Payments or any part thereof, and that such payments, in whole or in part, represent sufficient consideration to Employee for the terms of this Agreement.

In other words, Employee is not and shall not be entitled to any payment or other benefits other than those described in this Agreement. Employee also affirms that Employee has been paid and/or has received all compensation, wages, bonuses, commissions, and/or benefits to which Employee may be entitled. Except as set forth in this Agreement, Employee agrees that Employee is not entitled to any additional payment or benefits from the Company, including, but not limited to, expense reimbursements, bonuses, commissions, severance, retention payments, equity awards, attorneys’ fees, or any other compensation or benefit.

(h) The Company’s obligation to pay the Consideration Payments set forth herein is subject to Employee’s performance of Employee’s obligations as set forth herein and any breach of Employee’s obligations under this Agreement or any other post-termination obligations shall entitle the Company to cease any further Consideration Payments.

15. Governing Law and Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania.

The prevailing party in any such action will be entitled to recover its attorneys’ fees and costs.

16. Remedies. Employee acknowledges and agrees that, if Employee violates the covenants and agreements set forth in this Agreement, the Company would suffer irreparable harm, and that such harm to the Company would be impossible to fully measure in monetary damages. Accordingly, Executive acknowledges and agrees that, in addition to any other remedies which the Company may have at law or in equity or under the terms of this Agreement, the Company will have the right to have all obligations, undertakings, agreements, covenants, and other provisions of this Agreement specifically performed by Employee; the Company will have the right to obtain temporary, preliminary, and permanent injunctive relief to secure specific performance, and to prevent a breach or contemplated breach, of this Agreement; and Company will also be entitled to an accounting and repayment of all profits, compensation, remunerations, or benefits which Executive or others, directly or indirectly, have realized or may realize as a result of, growing out of, or in conjunction with any violation of this Agreement.

18. 409A Compliance. Notwithstanding anything herein to the contrary, (i) if at the time of Employee’s termination of employment with the Company, Employee is a “specified employee” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to Employee) to the extent necessary to comply with the requirements of Section 409A of the Code until the first business day that is more

Page 9 of 11

than six (6) months following Employee’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code) and (ii) if any other payments of money or other benefits due to Employee hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Section 409A of the Code, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Company’s Board of Directors, that does not cause such an accelerated or additional tax. In the event that payments under this Agreement are deferred pursuant to this paragraph in order to prevent any accelerated tax or additional tax under Section 409A of the Code, then such payments shall be paid at the time specified under this Paragraph 20 without any interest thereon. The Company shall consult with Employee in good faith regarding the implementation of this Paragraph 20; provided that neither the Company nor any of its employees or representatives shall have any liability to Employee with respect to the imposition of any early or additional tax under Section 409A of the Code. Notwithstanding anything to the contrary herein, to the extent required by Section 409A of the Code, a termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of amounts or benefits upon or following a termination of employment unless such termination is also a “Separation from Service” within the meaning of Section 409A of the Code and, for purposes of any such provision of this Agreement, references to a “resignation,” “termination,” “termination of employment” or like terms shall mean “Separation from Service.” For purposes of Section 409A of the Code, each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code.

19. Acknowledgment. This Agreement contains a release of Employee’s claims against the Company and Released Entities. Employee is advised to consult with an attorney as to whether to sign this Agreement. Employee has been given twenty-one (21) calendar days (“Consideration Period”) to consider this Agreement before signing it and returning it to Wendy Livingston, Chief Human Resources Officer at the Company’s corporate office at 350 Poplar Church Road, Camp Hill, PA 17011. In the event Employee executes and returns this Agreement prior to the end of the Consideration Period, Employee acknowledges that Employee’s decision to do so was voluntary and that Employee had the opportunity to consider this Agreement for the entire Consideration Period.
