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 press release. 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, 2025 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: PCTs’ ability to obtain funding for our operations, future capital requirements and future growth, and to continue as a going concern; PCT’s ability to meet, continue to meet, and comply on an ongoing basis with, the numerous regulatory requirements applicable to our PureFive® resin both generally and in food-grade applications and, more broadly, the operations of our 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 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 our 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 Engineering, LLC, 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 us and our subsidiaries by the funding for our operations, including the funding for the Ironton Facility and the Planned Facilities (as defined below); PCT’s ability to minimize or eliminate the many hazards and operational risks at our manufacturing facilities that can result in potential injury to individuals, disrupt our business, including interruptions or disruptions in operations at our facilities, and subject us to liability and increased costs; PCT’s ability to complete the necessary funding with respect to, and complete the construction of, the new polypropylene recycling facility in Thailand (the "Thailand Facility"), our first commercial-scale European plant located in Antwerp, Belgium (the "Belgium Facility"), and the purification facility to be built in Augusta, Georgia (the "Augusta Facility" and, together with the Thailand Facility and the Belgium Facility, the “Planned Facilities”) in a timely and cost-effective manner; PCT’s ability to procure, sort and process polypropylene plastic waste at our 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, which includes our ability to bring a total of one billion pounds of installed polypropylene recycling capability online by 2030, and our ability to meet related construction, regulatory, and financing requirements; the ability to negotiate multi-year offtake agreements at appropriate margins to fund ongoing operations; the possibility that PCT may be adversely affected or potentially impacted by 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 Feed PreP and purification facilities), including those changes caused by inflation, tariffs and supply chain conditions, such as increased transportation costs and global conflicts, 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, and the temporary spike in prices due to global conflicts such as the current conflict in the Middle East; the development of direct competitors in the recycled polypropylene segment that could impact the demand for PCT’s products; the outcome of any legal or regulatory proceedings to which PCT is, or may become, a party; geopolitical risk and changes in applicable laws or regulations; changes in the prices and availability of labor (including labor shortages), turnover in employees, and increases in employee-related costs; any business disruptions due to political or economic instability, pandemics, or armed hostilities (including the ongoing conflict between Russia and Ukraine and instability in the Middle East); and operational risks associated with the ability to operate the Ironton Facility and the Planned Facilities, as and when operative, at nameplate capacity. PCT undertakes no obligation to update any forward-looking statements made in this press release to reflect events or circumstances after the date of this press release or to reflect new information or the occurrence of unanticipated events, except as required by law.​​ Should one or more of these risks or uncertainties materialize or should any of the assumptions made prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events.​

Non-GAAP Financial Measures PCT uses certain financial measures that are not calculated in accordance with generally accepted accounting principles in the U.S. (“GAAP") to supplement its financial statements. The Company's primary non-GAAP financial measures are EBITDA and Adjusted EBITDA. The Company defines EBITDA as net income before interest expense, interest income, taxes and depreciation and amortization. Adjusted EBITDA is defined as EBITDA further adjusted to exclude certain non-cash items and other items that are not indicative of the Company’s core operating activities. This supplemental information should not be considered in isolation or as a substitute for the GAAP measures presented herein. The table at the end of this presentation provides a reconciliation from Net Income (Loss) to EBITDA and Adjusted EBITDA for the specified periods.

Regulation Is Accelerating Customer Focus and Adoption Mandates with dates create demand with dates, and the same shift converting demand in the US is now advancing across Europe and Asia. Overview Operations Commercial Growth Finance United States Expected demand for Ironton • New Jersey approval secured in May: one-year conditional, with a path to permanent • Requirement rises to 20% in 2027; food-contact exemption expires January 2027 • California SB54 in effect: 10% source reduction by 2027, 20% by 2030, 25% by 2032 • PureFive® qualifies as recycled content via APR certification Europe Expected demand for Antwerp • Packaging and Packaging Waste Regulation: recycled-content mandates for plastic packaging • End-of-Life Vehicles Regulation: recycled-content requirements for automotive plastics • PureFive® is REACH certified, with growing interest in serving European demand from Ironton Asia Expected demand for Thailand • Japan approved physically recycled polypropylene for food contact in September 2025, opening regional demand • Mitsui and RM TOHCELLO partnership announced July 2026, advancing PureFive® toward Japanese flexible packaging What the mandates drive right now • QSR cups are the single largest demand pull for recycled polypropylene, and the New Jersey approval accelerated qualification at major QSRs • Take-out containers: demand building from thousands of restaurant owner-operators who must comply in New Jersey, with converters launching compliance-specific lines • Food contact containers and packaging; e.g. New Jersey requires any container between 8oz and 5 gallons to have recycled content and California impacts all plastic packaging • 17 active trials are tied directly to New Jersey compliance • Clear thermoformed food packaging sits squarely in the mandate, and compounding lets us supply multiple grades to match customer requirements • Requirements step up over time, so qualification work done now supports multi-year volume opportunities
