      <remarks>Timothy Johnston ceased to be affiliated with the Issuer on May 31, 2024. (1) Based upon the closing price of $4.74 per Common Share of Li-Cycle Holdings Corp. (the 'Issuer') on July 5, 2024. (2) As part of a reorganization in connection with a reverse takeover transaction of the Issuer, Timothy Johnston, through Keperra Holdings Limited, a corporation organized under the laws of Ontario, Canada and successor to Keperra Holdings Ltd., exchanged equity of Li-Cycle Corporation for 1,130,895 Common Shares of the Issuer. (3) All share amounts herein reflect a June 3, 2024 share consolidation of the Common Shares of the Issuer at a ratio of one post-consolidation Common Share for every eight pre-consolidation Common Shares (disclosed on the Issuer's Form 8-K filed by the Issuer on June 4, 2024).</remarks>
