1. What was announced today?

• Li-Cycle entered into a business combination agreement with Peridot Acquisition Corp. (Peridot), commencing a process that will result upon closing of the business combination in the combined company becoming a public company in the U.S. listed on the New York Stock Exchange (NYSE) under the ticker symbol “LICY.”

• We expect the combination with Peridot to further bolster our position as the largest battery recycler in North America and facilitate our global expansion by funding and accelerating the company’s growth strategy.

2. Why did Li-Cycle decide to go this route?

• By combining with Peridot to become a public company, we immediately elevate the opportunities and resources available to us as we continue to leverage our proven Spoke & Hub technologies to provide the world with an efficient and sustainable process of recovering critical, finite materials from batteries.

3. Who is Peridot?

• Peridot Acquisition Corp. is a New York Stock Exchange-listed SPAC whose sole purpose is to identify, acquire and maximize the value of companies that focus on environmentally sound infrastructure, industrial application and disruptive technologies that enhance resilience to climate change, such as Li-Cycle.

• The Peridot team has significant public company board experience and sophisticated anchor investors.

4. Why did you choose to work with Peridot?

• Li-Cycle and Peridot share a commitment to creating a purpose-driven business that both combats climate change and makes money while doing so.

• The alignment, resources and commitment between Li-Cycle and Peridot will enable us to fulfill our mission – to leverage our revolutionary Spoke & Hub technologies to address an emerging and global challenge resulting from the acceleration in electric vehicles and energy storage.

5. Why did Peridot identify Li-Cycle as an opportunity?

• Peridot appreciated that Li-Cycle was motivated not only by a desire to build a large, highly profitable and enduring business, but also by a desire to battle climate change.

• Peridot recognized the opportunity stemming from the lack of sustainable resource recovery methods from lithium-ion batteries across the globe - and valued how Li-Cycle is a scalable, sustainable and safe battery resource recovery solution especially in comparison to the alternative solutions currently available.

• The Peridot team is excited to combine with Li-Cycle, a company that is the largest battery recycler in North America and a company that they know to be well-equipped to expand globally.

• Additionally, Peridot understands the massive electrification ramp that is occurring and how lithium-ion recycling is an imperative solution with the accelerated demands of batteries as the world transitions into an electric future.

6. What are the terms of the business combination?

• The business combination values Li-Cycle at an implied $1.67 billion pro forma equity value.

• Li-Cycle will raise proceeds of $615 million through the business combination, including a $315 million fully committed PIPE investment from institutional investors.

7. Did you consider an IPO?

• Li-Cycle has evaluated many opportunities to support the company’s growth and execute on our vision to deliver value while saving the planet. This approach to entering the public markets made the most sense strategically for Li-Cycle, as we continue to aggressively expand our presence in North America and enter additional global markets.

• After close evaluation, the opportunity to partner with Peridot to take Li-Cycle public made the most sense to quickly take the company to the next chapter of growth and better position the business to lead the market moving forward.

8. When is the deal expected to close / when will Li-Cycle become public?

• The proposed transaction is expected to close in the second quarter of 2021.

9. What does this mean for me as an employee of Li-Cycle?

• We will continue to operate under the Li-Cycle name and there will otherwise be no meaningful changes to the team or how we do business.

• As we enter this new chapter, however, there are some rules we must all follow: there will be new reporting requirements for the combined company, some restrictions on financial trading for certain “insiders”, including employees, and the Securities and Exchange Committee (SEC) has strict guidelines governing external communications.

• To avoid delays or any other repercussions the SEC might impose if we do not adhere to these rules, we have designated certain spokespersons for Li-Cycle who can speak to the proposed transaction on behalf of the company and we ask that you please avoid making any statements publicly or privately to any third party.

• Accordingly, you must refrain from making statements about our company or our performance in open forums (e.g., online, to friends, on Facebook, Twitter, LinkedIn, via email, to existing or prospective customers, etc.). This means you cannot share or promote anything other than what Li-Cycle has put out on our official Li-Cycle channels. So, you can share the LinkedIn update and Tweet from Li-Cycle’s page, but not any third-party statements orotherwise about the transaction. For further guidance and instruction on the rules governing social media communications, please see the social media guidelines attached.

• If someone – especially a member of the press – asks you about Li-Cycle plans to go public or its company fundamentals, the best response is something polite like, “We’re really proud and excited, but it’s business as usual at Li-Cycle.” If pushed further, you should offer to connect the inquirer with the appropriate team members.

• For any inquiries from press or otherwise, please forward details of the inquiry to the team at media@li-cycle.com, who can help handle such requests appropriately during this sensitive time.

• Additionally, if you have any plans to participate in a public event, policy forum, conference, regulatory intervention, or anything else of that nature, please check in with us at media@li-cycle.com so that we can make sure you are aware of any updated restrictions or guidance and we can comply with any related filing requirements or otherwise.

• As soon as you receive any new speaking requests, please share them with us at media@li-cycle.com.

10. How does this benefit me as an employee of Li-Cycle?

• We believe entering the public markets will significantly help us execute our global growth strategy.

• Going public unlocks new opportunities and resources that will accelerate our growth in North America and expand into additional global markets.

• We hope our employees will take pride in our collective efforts to become the global leader in sustainable lithium-ion battery recycling.

11. Can I buy stock in the company?

• Once Li-Cycle is publicly traded, you will be able to purchase Li-Cycle stock on the open market.

• Please know, however, that certain Li-Cycle employees will be subject to “blackout” periods, during which company stock cannot be bought or sold (typically for several weeks prior to and until a day or two after our quarterly earnings have been announced), and no purchases or sales of company stock by an employee will be permitted at any time when an employee otherwise has “material nonpublic information” regarding Li-Cycle.
