Hello everyone and thank you for joining us as we walk through the recently announced TLGY Acquisition Corporation and Verde Bioresins business combination. Through this presentation we will introduce Verde Bioresins, the transaction overview, and the investment opportunity at hand.

This is a friendly reminder that this presentation contains forward looking information and may not be reflective of actual performance. For more information, view slides 25 through 26 of the investor presentation filed on June 20, 2023, available on the TLGY Acquisition Corporation website.

So, Verde Bioresins is a bioresin company that's revolutionizing the global plastics market with a viable green biodegradable solution for the circular economy. There's been a growing coalition of countries, cities, institutions, and businesses around the world that are pledging to eliminate plastic pollution entirely and have been looking for sustainable and scalable alternatives.

Governments, shareholders, and customers demand that Fortune 500 companies pursue eco-friendly alternatives. Yet, despite this, existing bioplastics players in the market make up only less than 2% of the plastics market to date.

We can see that multinational companies are targeting 100% renewable and biodegradable or recyclable packaging by 2025. Just as you can see, PepsiCo, McDonald’s, Walmart, and Target are all members of that group.

Verde has prepared a market-ready breakthrough technology called PolyEarthylene^TM. It's a first-of-its-kind proprietary bioresin, recognised by market leaders such as Vinmar Polymers America potentially as one of the first viable replacements for conventional plastics. The market that Verde is addressing is significant at $600 billion globally, and Verde assumes that they can address up to $300 billion of this market in the long run. Currently, the bioplastics industry makes up less than 2% of this market.

So, PolyEarthylene^TM is a biodegradable resin replacement poised for significant market acceleration and is ready for rapid deployment, addressing all critical industry requirements. It demonstrates superior qualities against bioplastics alternatives that currently exist in the market.

So, Verde Bioresins has already completed R&D, environmental testing, infrastructure process and application validation, and is at the stage of acquiring their first major customers. They've already signed up Vinmar Polymers America, who has brought them on board to help acquire those first customers, and Vinmar has validated that their product is a viable solution for this market.

What makes Verde Bioresins so unique is that it's drop-in ready to existing infrastructure. What this means is existing plastics manufacturers in the market do not have to overhaul their factories or create new production processes and can take the resin and plug it into their existing plastic manufacturing processes, making it scalable and ready for mass market adoption.

Verde’s ready to move on with these early adopters and scale up the business rapidly and is now in the phase of customer adoption and marketing and translation into the existing infrastructure of those customers.

So, PolyEarthylene^TM is setting a new standard for bioplastics. You can see that it's a really viable end-of-life solution that ticks all the boxes. It's low cost in comparison to other bioplastics and is cost competitive with existing non-biodegradable plastics on the market.

It's scalable because it's drop-in ready to existing manufacturing infrastructure, and it has broad applications of end use life. It can be used for a number of different purposes that other incumbent bioplastics cannot be used for.

Verde’s growth catalysts are driven by partnerships, production, and a pipeline of early adopting customers. Verde's building capacity to deliver $75 million of PolyEarthylene^TM to satisfy year one and year two demand for the product.

Strategic partnerships through Vinmar Polymers America help them tap into new customers and new markets around the world and facilitate introductions to the incumbent plastic manufacturers worldwide.

Braskem is also a strategic supplier to Verde and helps them secure ample feed stock to produce the amount of PolyEarthylene^TM required to meet year one and year two projections.

The financial forecast over on the right-hand side shows rapid growth from year one to year two in adjusted sales, gross profit, and EBITDA.

PolyEarthylene^TM was developed to be a drop in bioresin on existing industry infrastructure to accelerate market entry. The main problem with existing incumbent bioplastics like PLA, PHA, PBAT, and PVOH are that they do not have as many broad applications as Verde. There are significant issues with producing existing plastic products that we all use day-to-day, such as food packaging, heat resistant materials, or strong materials.

Verde’s product is able to address a broad application of these uses while maintaining landfill biodegradability. There's a $250 million backlog of potential demand for rigid disposable packaging, durable goods, and flexible packaging, much like the examples you see on the middle right.

Verde's leadership team is experienced entrepreneurs and strong operators. Verde's Chairman, President and COO Brian Gordon brings over 20 years of C-level experience with roots in IBM and Merck & Co., and he has diverse background in CFO and COO expertise in the consumer products and services company space. Verde's CEO Joseph brings over 40 years of petrochemical experience, extensive commodity engineering and resin experience as well.

With that, and Verde merging with TLGY Acquisition Corporation, TLGY’s founder, Jin-Goon Kim, brings over 20 years of experience in private equity, setting the company up for success with financing. Jin-Goon was a former partner at TPG Capital and spearheaded over $40 billion in value creation with the number one auto platform [in China], sportswear, and was awarded TPG CEO and [industry’s] Man of the Year.

Next, we'll move on to the transaction overview and the unique SPAC structure that TLGY Acquisition Corporation has set up to poise this transaction in the best possible way.

So, TLGY Acquisition Corporation has spearheaded structural innovation with a fixed pool of warrants and conversion-to-common mechanism that creates upside potential and downside protection for investors. This is potentially sufficient incentive to buy shares in the open market before the DeSPAC completes.

There's a naturally embedded multiplier that quickly escalates upside and downside protection as redemption rises. There’s an alignment of interests between public shareholders, the target company, and the sponsor with performance-based economics such as a 35% IRR earnout threshold.

The SPAC transaction overview consists of a $57.6 million sponsor, a $73.2 million TLGY public shareholder pool, and $365.0 million to Verde [in total representing $496 million in pro forma equity value]. You'll see over on the right-hand side there's a sources and uses chart that details the cash to the balance sheet being $63 million post DeSPAC transaction.

The bottom chart really helps us illustrate a scenario in which 90% redemption arises and the shareholders receive more shares as redemption rate rises to offset the downside loss.

This is the unique structure that TLGY Acquisition Corporation has deployed that allows protection against downside risk and upside potential at the same time. We'll notice that on the post DeSPAC transaction that investors are able to capture upside if price rises and that there is downside protection if price declines to a $4 scenario at the 90% threshold.

Thank you very much for listening to this walkthrough of the TLGY Acquisition Corporation and Verde Bioresins teaser walkthrough. We're very excited and happy to have you listen. Please reach out to invest@tlgyacquisition.com if you have any questions or would like to connect with the management team.

We also urge you to check out the media section on the TLGY or Verde website for a great array of podcasts and events and media coverages that will talk through the SPAC structure and have the founder Jin-Goon Kim explain this unique innovation and how this really pioneers a new page in the SPAC industry with a very exciting and promising target. Thank you very much.
