Li-Cycle Provides Update on Annual General and Special Meeting Results

Board of Directors Approves Share Consolidation on an 8-for-1 Ratio

Board of Directors Announces Jacqueline Dedo as Li-Cycle’s Independent Board Chair

TORONTO, Canada (May 24, 2024) – Li-Cycle Holdings Corp. (NYSE: LICY) (“Li-Cycle” or the “Company”), a leading global lithium-ion battery resource recovery company, today announced updates from the Company’s Annual General and Special Meeting of Shareholders held on May 23, 2024 (the “AGM”).

Voting results of items of business at the AGM included the election of each of the Li-Cycle director nominees; the approval of the share consolidation resolution, described further below; the approval of the compensation of the Company’s named executive officers on an advisory basis; the approval of a one-year frequency period for future advisory votes on the compensation of the Company’s named executive officers on an advisory basis; and the approval of the adjournment of the AGM to permit Li-Cycle to complete the search for a successor independent auditor firm.

Share Consolidation Update

Following approval by the Company’s shareholders and its Board of Directors (“Board”), the Company will effect a consolidation of the Company’s common shares (the “Shares”) at a ratio of 8 pre-consolidation Shares for 1 post-consolidation Share (the “Share Consolidation”).

The Share Consolidation is expected to be effective before the markets open on June 4, 2024. Beginning on June 4, 2024, Li-Cycle’s Shares are expected to begin trading on a post-consolidation basis on the New York Stock Exchange (“NYSE”) under the same symbol, “LICY,” but under a new CUSIP number: 50202P204.

The Share Consolidation is being implemented as a way to potentially increase the trading price of Shares so as to regain compliance with the closing share price criteria set forth in Rule 802.01C of the NYSE Manual.

Under the terms of the Share Consolidation, every eight Shares will be automatically consolidated into one Share. The Share Consolidation will not change the authorized number of Shares.

Shareholders will not receive any fractional Shares as a result of the Share Consolidation. In the event that a shareholder becomes entitled to a fractional Share as a result of the Share Consolidation, such fractional Share will be deemed to have been tendered by the shareholder immediately following the Share Consolidation to the Company for cancellation for no consideration.

As a result of the Share Consolidation, the exercise or conversion price and the number of Shares issuable under any of the Company’s outstanding securities that are exercisable or convertible into Shares, including under equity awards, warrants, rights, convertible notes and other similar securities will be proportionally adjusted in accordance with the terms of such securities.

Continental Stock Transfer and Trust Company (“Continental”), the Company’s transfer agent, will act as the exchange agent for the Share Consolidation. Shares held by shareholders in ‘street name’ will have their accounts automatically credited by their brokerage firm, bank or other nominee, as will any shareholders who held their Shares in book-entry form at Continental.

Independent Board Chair Update

The Company would also like to announce the appointment of Jacqueline (Jacqui) Dedo as Li-Cycle’s independent Board Chair, effective immediately. Ms. Dedo succeeds Tim Johnston, Li-Cycle’s previous interim non-executive Board Chair. As part of this transition, Mr. Johnston is also stepping down from the Li-Cycle Board, effective May 31, 2024, to pursue other business opportunities. Ms. Dedo will continue to serve as the Chair of the Board’s Special Committee.

“Having served on our Board for almost two years, Jacqui has a deep understanding of Li-Cycle and the opportunities ahead for our technology and business,” said Ajay Kochhar, CEO and co-founder of Li-Cycle. “I look forward to Jacqui’s enhanced contributions, continued guidance and leadership as our new independent Chair of the Board as we advance our comprehensive review and go-forward strategy for the Rochester Hub. Her strategic advice and counsel will be an invaluable differentiator as we continue to respond to a rapidly growing market and new opportunities for Li-Cycle.”

“I want to extend my gratitude to Tim for his leadership and vision as Chair of the Board and for helping us create a strong foundation upon which we can build,” continued Mr. Kochhar. “It was a privilege partnering with Tim to found Li-Cycle in 2016; his significant contributions have been a critical enabler of the development of our technology and the development of our Company.”

“I believe that the underlying opportunities for Li-Cycle’s business model and its patented and innovative Spoke & Hub Technologies^™ continue to be robust and position the Company favorably in the global battery recycling market. I am excited to take on this leadership position as the Company navigates this transitionary period and seeks to execute on its next phase of growth,” said Jacqui Dedo, Li-Cycle’s new Independent Board Chair.
