RRSP Eligibility. In accordance with the terms and conditions of such RRSP plan(s) in effect and as amended from time to time, your participation in Li-Cycle’s RRSP plan(s) shall continue until the conclusion of the statutory notice period on the Separation Date, after which time all such participation shall automatically cease.

Benefits Continuance. You will continue to participate in the Executive Plans (which are comprised of Ancillary Coverages, Perquisites, and Primary Coverages, as such terms are defined in your Employment Agreement) until the Separation Date, after which time the Ancillary Coverages and Perquisites will automatically cease. Thereafter, subject to all applicable plan terms and conditions, in place and as amended from time to time, as well as the approval of the respective insurers, you will continue to be entitled to participate in the Primary Coverages until the earlier of May 22, 2025 (being the end of the Advisory Period) or the date on which you become entitled to participate in similar benefit plans with another employer, at which point all Primary Coverages will automatically cease. As a condition of this agreement, you agree to immediately advise Li-Cycle of your participation in benefits plans through an alternate employer. Life insurance coverage may, at your option, be converted from group to individual coverage within 30 days of the Separation Date. Health and Dental coverage may, at your option, be converted from group to individual coverage within 90 days of the cessation of coverage. For further details, please ***@*** or via telephone at ###-###-#### (toll free).

Short Term Incentive Plan (STIP). As agreed, although the Board of Directors, at its sole discretion, has not yet determined if STIP payments will be awarded in respect of the FY 2024 performance period, you shall have no further or other entitlement to STIP or any form of compensation or damages in lieu of the same.

LTIP/Executive Share Ownership. For greater certainty, your eligibility under the long-term incentive plan (“LTIP”) in connection with and following the cessation of your employment, and any executive share ownership requirements in place and as amended from time to time, shall terminate on the Separation Date. Your unvested PSUs and RSUs shall be forfeited on the Separation Date. Your vested RSUs shall be eligible for settlement in the ordinary course. You do not hold any options. Please access your “Shareworks by Morgan Stanley” account for further information in this regard.

Mutual Release & Indemnity. As a condition of receiving the amounts and benefits set out in this agreement, you agree and acknowledge that you will sign and deliver either by hand or via email to the attention of Christine Barwell, CHRO, (i) the Acknowledgement below and (ii) the Mutual Release & Indemnity, attached at Schedule “A” hereto by no later than 5:00 pm EST on May 22, 2025. For certainty, you will have no obligations under the Mutual Release & Indemnity or this agreement should the Company not comply with its obligations hereunder. The Company will sign and deliver to you a copy of the Mutual Release & Indemnity by the same time and date as set out above, and will comply with its obligations thereunder. Litigation Cooperation. As a condition of this agreement, you agree that you will cooperate with, and make yourself readily available to, Li-Cycle, its affiliated and related businesses, and/or their respective advisers, as Li-Cycle may reasonably request, to assist in any dispute by any third party against any of the Releasees (as such term is defined in the attached Mutual Release & Indemnity), including providing information, in the form of documentation and/or witness statement(s) and/or testimony, for any litigation, potential litigation, internal investigation, or administrative, regulatory, judicial or quasi-judicial proceeding involving Li-Cycle (and/or its related or affiliated entities) about which you have experience or information; provided that you will have no obligation to support any of the Releasees in any restructuring or insolvency proceeding under the CCAA or otherwise. Li-Cycle will reimburse you for your time spent on litigation matters at the request of the Company or its counsel at a rate of CAD $3,000 per day (CAD $1,500 per half day) and for any reasonable expenses incurred by you as a consequence of complying with this paragraph 5, provided that such time and expenses are approved in advance by Li-Cycle. For clarity, this litigation cooperation provision does not preclude, and should not be interpreted as precluding, any lawful, good faith report under applicable whistleblower legislation by you or otherwise complying with disclosure or similar obligations required by law and will not require services of such magnitude as they will interfere with your ability to obtain and maintain alternate employment or engagement.

Mutual Non-Disparagement. You acknowledge and confirm that you will comply with your post-employment non-disparagement obligations set out in the attached Mutual Release & Indemnity. Further, Li-Cycle agrees that it will not make any corporate statements disparaging you and the Company will direct all members of the Company’s Board of Directors and management not to do so.

Deductions and Withholdings. All payments and arrangements in this letter agreement are subject to all applicable statutory deductions and withholdings.

Legal Expenses. Subject to and conditional upon your agreement to and full execution of this letter agreement and the attached Mutual Release & Indemnity, Li-Cycle agrees to pay your legal expenses personally incurred in respect of the termination of your employment and the resolution of the terms of the termination of your employment, up to an aggregate maximum of CAD $10,000 + HST, to be paid directly to your legal counsel, Blake, Cassels & Graydon LLP, in trust, within two business days of receipt of an invoice from the law firm. Your execution of this letter shall constitute your lawful direction of such funds as contemplated by this section.

Indemnification: Subject to and in accordance with the terms and conditions of the same, you will continue to be covered by and subject to the Director and Officer Indemnification Agreement as between you and Li-Cycle Holdings Corp., dated March 26, 2025, which is not amended by this agreement.

Other Matters. You hereby agree to:

return all Li-Cycle property in your possession or under your control, stored in any form whatsoever, together with any copies, by contacting Robert Schenkel via email by no later than 5:00pm on May 22, 2025 as set forth in section 5.13 of your Employment Agreement;

comply, at all times up to and following the Separation Date, with all of your ongoing fiduciary, common law, as applicable, and any enforceable contractual post-employment obligations, including pursuant to your Employment Agreement (including the clawback provisions at section 3.5 therein, the non-competition and non-solicitation covenants at Article 6 therein, and the confidentiality and intellectual property-related covenants set out in the Confidentiality and Intellectual Property Rights Agreement attached to the Employment Agreement at Exhibit “A”) and the attached Mutual Release & Indemnity;

take all steps set forth under section 5.12 of your Employment Agreement or otherwise to evidence the resignation of all directorships and offices with Li-Cycle or any subsidiaries or affiliates of the Company; and

maintain confidentiality with respect to the terms and conditions of this letter agreement and not disclose the same to any person or entity other than your spouse, your legal counsel or financial advisor, or as required by law. Any party to whom you make permitted disclosure must also maintain confidentiality with respect to the terms and conditions of this letter agreement.
