Exhibit 99.1

PureCycle Technologies, Inc. Provides First Quarter 2021 Corporate Update

- Began trading on NASDAQ under the ticker “PCT” on March 18, 2021

- Total cash balance of $570 million ($318 million of which is restricted) at quarter-end March 31, 2021

- Construction of first manufacturing plant in Ironton, OH (“Plant 1”) began in October 2020 and continues to progress as planned; continue to expect the facility to be commercially operational by the end of 2022 with an annual installed production capacity of 107 million pounds

- Expect approximately 1 billion pounds of installed capacity by the end of 2024; near term planning for the next series of manufacturing facilities is underway and is expected to be sited in the United States (“cluster” site model) followed by Europe

ORLANDO, Fla., May 17, 2021 – PureCycle Technologies, Inc. ("PureCycle” or “the Company") (NASDAQ: PCT), a company focused on polypropylene recycling, today announced a corporate update and financial results for the first quarter ending March 31, 2021.

Management Commentary

“Polypropylene is one of the largest contributors to the global plastics waste crisis, and PureCycle is unlocking a large and under-penetrated market with our patented purification recycling technology, licensed from The Procter & Gamble Company (P&G), for converting waste polypropylene into virgin-like resin. The market demand for polypropylene is enormous at over 160 billion pounds annually and expanding rapidly with global demand expected to exceed 200 billion pounds by 2025. This demand, coupled with increasing international focus from regulators and consumers on sustainable plastic solutions, creates significant global opportunities for PureCycle. We have continued to achieve our strategic goals and milestones over the course of the first quarter, further developed our financial profile with additional liquidity, enhanced our manufacturing capabilities, and strengthened our world-class team to position the Company for the future,” said Mike Otworth, PureCycle’s Chairman and Chief Executive Officer.

The Company is pleased with the progress during the first quarter, highlighted by PureCycle becoming a public company, remaining on-track with the construction schedule for the Company’s first manufacturing plant in Ironton, Ohio (“Plant 1”), and starting line engineering on the second commercial facility. PureCycle maintains a strong balance sheet with $570 million in cash and cash equivalents following the closings of multiple transactions with investors who have conducted significant due diligence on various aspects of the Company’s business. PureCycle has the capital needed to complete construction of Plant 1 and commence funding of subsequent commercial facilities.

PureCycle remains confident in the efficacy and scalability of its technology as well as its manufacturing capabilities. The Company’s technology has had over 350 lab scale tests over the last seven years and almost two years of successful operation of the Feedstock Evaluation Unit (FEU). This technology has been evaluated extensively by an independent engineering firm as well as PureCycle’s strategic partners. Furthermore, the technology was invented by P&G and is protected through an extensive patent portfolio.

The FEU has been operational since July 2019 to test and optimize the efficiency, commercial design, scale up, and throughput of the purification process. The FEU has also been instrumental in validating suitable feedstocks that enabled full contracting for Plant 1. Additionally, the FEU continues to provide product samples to current and future customers for their extensive application testing requirements.

The PureCycle team is committed to the goal of transforming waste polypropylene into sustainable, high-quality products. The Company has every confidence in the recently assembled world-class team, the strength of the technology, and patent estate. PureCycle’s capabilities afford the opportunity to transform an immense global problem into a sustainable solution that will drive shareholder value well into the future.

Liquidity and Capital Allocation

Cash and cash equivalents totaled $570.1 million, including $317.5 million in restricted cash, at quarter end March 31, 2021. In conjunction with closing the business combination, the Company received $326 million of gross proceeds related to the transaction closing and the release of the PIPE investment funds ($250.0 million aggregate purchase price based on 25 million issued shares of common stock at $10.00 per share). The gross proceeds were offset by $28.0 million of capitalized issuance costs.

PureCycle had debt of $310.0 million as of March 31, 2021. This included $250.0 million revenue bond issuance on October 7, 2020, by the Southern Ohio Port Authority and $60.0 million of convertible notes issued at 5.875% due October 15, 2022. PureCycle estimates approximately $266.0 million in remaining cost to complete Plant 1, in line with original estimates.

Timeline for Form 10-Q Submission

As a result of recent public comments from the SEC regarding the treatment of certain warrants similar to some of those issued in the initial public offering of Roth CH Acquisition I Co. prior to the Company’s business combination, the Company has made the decision to treat such warrants as a liability under its balance sheet, rather than equity. While the Company does not believe this change will have a material impact on the balance sheet or the remainder of the financial statements, the completion of the required documentation and reviews may prevent the Company from filing its quarterly report on Form 10-Q today. Consequently, the Company may utilize the relief offered by the SEC under Rule 12b-25 under the Securities Exchange Act of 1934 and may file its quarterly report on Form 10-Q within five days following the normal reporting deadline.
