Second Quarter 2025Corporate Update August 7, 2025

Forward-Looking Statements This presentation contains forward-looking statements, including statements about the continued execution of PureCycle’s business plan, the expected results of tests and trials, the expected timing of commercial sales, and planned future updates. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements generally relate to future events or PureCycle’s future financial or operating performance and may refer to projections and forecasts. Forward-looking statements are often identified by future or conditional words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions (or the negative versions of such words or expressions), but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements are based on the current expectations of PureCycle’s management and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of this presentation. There can be no assurance that future developments will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described in the section entitled “Risk Factors” in each of PureCycle’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and PureCycle’s Quarterly Reports on Form 10-Q for various quarterly periods, those discussed and identified in other public filings made with the Securities and Exchange Commission by PureCycle and the following: PCT's ability to obtain funding for its operations and future growth and to continue as a going concern; PCT's ability to meet, and to continue to meet, applicable regulatory requirements for the use of PCT’s PureFive™ resin in food grade applications (including in the United States, Europe, Asia and other future international locations); PCT's ability to comply on an ongoing basis with the numerous regulatory requirements applicable to the PureFive™ resin and PCT’s facilities (including in the United States, Europe, Asia and other future international locations); expectations and changes regarding PCT’s strategies and future financial performance, including its future business plans, expansion plans or objectives, prospective performance and opportunities and competitors, revenues, products and services, pricing, operating expenses, market trends, liquidity, cash flows and uses of cash, capital expenditures, and PCT’s ability to invest in growth initiatives, which could be impacted by significant changes to tariffs on foreign imports; the ability of PCT’s first commercial-scale recycling facility in Lawrence County, Ohio, the Ironton Facility, to be appropriately certified by Leidos, following certain performance and other tests, and commence full-scale commercial operations in a timely and cost-effective manner, or at all; PCT’s ability to meet, and to continue to meet, the requirements imposed upon it and its subsidiaries by the funding for its operations, including the funding for the Ironton Facility; PCT’s ability to minimize or eliminate the many hazards and operational risks at its manufacturing facilities that can result in potential injury to individuals, disrupt its business (including interruptions or disruptions in operations at its facilities), and subject PCT to liability and increased costs; PCT’s ability to complete the necessary funding with respect to, and complete the construction of its new polypropylene recycling facility in Thailand, its first commercial-scale European plant located in Antwerp, Belgium, and the multi-line purification facility to be built in Augusta, Georgia in a timely and cost-effective manner; PCT's ability to execute its growth plan to bring an additional one billion pounds of installed polypropylene recycling capability online before 2030, including its ability to meet related construction, regulatory, and financing requirements; PCT’s ability to procure, sort and process polypropylene plastic waste at its planned plastic waste prep facilities; PCT’s ability to maintain exclusivity under The Procter & Gamble Company license; the implementation, market acceptance and success of PCT’s business model and growth strategy; the success or profitability of PCT’s offtake arrangements; the potential impact of economic, business, and/or competitive factors, including interest rates, availability of capital, economic cycles, and other macro-economic impacts (such as tariffs); changes in the prices and availability of materials (such as steel and other materials needed for the construction of future PreP and purification facilities), including those changes caused by inflation, tariffs and supply chain conditions, such as increased transportation costs, and our ability to obtain such materials in a timely and cost-effective manner; the ability to source feedstock with a high polypropylene content at a reasonable cost; PCT’s future capital requirements and sources and uses of cash; developments and projections relating to PCT’s competitors and industry; the outcome of any legal or regulatory proceedings to which PCT is, or may become, a party including the securities class action and putative class action cases; geopolitical risk and changes in applicable laws or regulations; the possibility that PCT may be adversely affected by other economic, business, and/or competitive factors, including interest rates, availability of capital, economic cycles, and other macro-economic impacts; turnover in employees and increases in employee-related costs; changes in the prices and availability of labor (including labor shortages); any business disruptions due to political or economic instability, pandemics, armed hostilities (including the ongoing conflict between Russia and Ukraine and the conflict in the Middle East); the potential impact of climate change on PCT, including physical and transition risks, higher regulatory and compliance costs, reputational risks, and availability of capital on attractive terms; and operational risk.

PCT Highlights Growth Capital raise to help fund the next phase of growth and lay foundation for expansion Unlocks path to 1 billion pounds of installed capacity and $600 million EBITDA1 per year by 2030 Strong relationship with IRPC allows for low-cost, accelerated expansion into Thailand Commercial Commercial agreement with Emerald Carpets for approximately 5 million pounds of fiber sales Engaged in 17 post-trial negotiations representing ~80 million pounds of potential cumulative annual PCT production volume across applications (not inclusive of compounded material) Pipeline continues to build with 26 active trials and 70 pending trials Successfully completed first industrial trial in a film application Earned Green Circle Certified's Recycled Content Certification Operations Initiated project to bring approximately 100 million pounds of annual compounding capacity to Ironton Achieved 87% onstream time in April/May and produced pellets for 65 consecutive days in Q2 Successfully completed rate test at 14,000 lbs/hr on August 1, nearly nameplate capacity Engaging third-party engineering firm to validate Ironton learnings for future plant design Finance Raised ~$300 million from perpetual preferred security in June Engaging with global banks for potential project financing Overview Growth Commercial Operations Finance 1. PureCycle defines EBITDA as net income before interest, income taxes, and depreciation and amortization. No reconciliation of EBITDA to net income for Ironton, Thailand Gen 1, Antwerp Gen 1, and Augusta Gen 2 is included in this presentation because PureCycle is unable to quantify certain amounts that would be required to be included in the GAAP measure without unreasonable efforts. In addition, PureCycle believes such reconciliation would imply a degree of precision that would be confusing or misleading to investors. For the same reasons, PureCycle is unable to address the probable significance of the unavailable information, which could be material to future results. We believe EBITDA is valuable for investors and analysts as it provides additional insight into each facilities' operational performance, excluding the impacts of certain financing, investing, and other non-operational activities.
