Announcement Regarding the Status of the Rochester Hub Project

On December 14, 2021, Li-Cycle Holdings Corp. (the “Company”) issued a press release to announce that it will increase the expected processing capacity of its first commercial Hub facility being developed near Rochester, New York from 25,000 to 35,000 tonnes of “black mass” annually (equivalent to approximately 90,000 tonnes of lithium-ion battery equivalent feed annually). Based on the results of the definitive feasibility study completed in December 2021, the Company expects to invest approximately $485 million (+/-15%) to develop the Rochester Hub. The Company expects to begin Hub construction by year-end 2021 and to reach mechanical completion, commissioning and start-up at the Rochester Hub in 2023, subject to receipt of applicable regulatory and other approvals.

Key design and cost changes relative to a June 2020 preliminary feasibility study include, but are not limited to: 1) higher material costs due to increased size and supply chain inflationary impacts; 2) scope alterations responding to contracted feed supplies and implementing environmental practices; and 3) up-sizing of nameplate output capacity of the Hub, resulting in approximately 250% higher Hub output capacity of nickel sulphate (approximately 42,000 to 48,000 tonnes per annum), approximately 160% higher output capacity of lithium carbonate (approximately 7,500 to 8,500 tonnes per annum), and approximately 65% lower output capacity of cobalt sulphate (approximately 6,500 to 7,500 tonnes per annum).

A press release issued by the Company announcing the increase in processing capacity at the Rochester Hub is included as an exhibit to this current report on Form 6-K.
