Executive Summary The Ironton Facility was negatively impacted by a severe thunderstorm which knocked out the power to southern Ohio and Ironton for an extended period of time  Given the negative impact on the Ironton Facility from the power outage, PureCycle is declaring force majeure as a result of the incident  Force Majeure was declared given uncertainties of PureCycle's ability to achieve one or more remaining milestones  We expect to have the plant restored and back online as soon as reasonably possible but this will be done methodically with a focus on safety and improving reliability

Force Majeure Timeline Event timeline On 7-August, the Ironton Facility experienced a full power outage for approximately 2 hours; the Ironton Facility initially recovered the next day without any identifiable significant issues. On 25-August, the mechanical component appeared to fail.  The Ironton Facility was cycled down, evaluated, and then returned to service within 4 days.  The mechanical component recovered without any obvious indication of ongoing problems.  On 3-September, that same mechanical component failed completely.  Two separate field repairs were attempted, but the component was deemed irreparable on 5-September.  The mechanical component was replaced with a spare on 9-September and the Ironton Facility is currently in the process of restarting.   Force Majeure Notice Following the 3-September event, two separate 3rd parties independently evaluated the component and determined that the failure was attributable to the 7-August full power failure of an outside supplier due to severe storms. Due to the extended outage which delayed plant production, the Company currently does not expect to meet the 30-September milestone in its Ohio bond agreements requiring one month's production of 4.45MM lbs. of ultra-pure recycled resin.     The Company intends to engage with bondholders but, in an abundance of caution, filed a Notice of Force Majeure with the Trustee on 13-September.

Ironton Facility Operations Update Now that the Ironton Facility mechanical component has been replaced, PureCycle is working methodically to reestablish operations.  Most recent final product quality (9/1) is on specification and has been certified by the onsite laboratory; we have achieved significant product quality improvements since June 2023.   The Ironton Facility expects to ship the first commercial customer orders soon.

Ironton is making solid progress Equipment issues; Normal startup activity. Mechanical in nature, not core tech; flange leaks, seal leaks, & screen leaks. Root Cause Failure Analysis (RCFA) have been performed on each failure with good reliability improvements implemented each time. Product quality improvements; Took several weeks longer to sweep the construction debris from the system to make on specification product quality. Current product quality is on spec which indicates all critical construction debris has been removed from system. Operations learning curve; PureCycle Ironton’s Operational Team is growing into a 24/7 operation, but at times it means slowing down to ensure the development of the right experience.  This complements our intent to safely, reliably, and methodically operate the Ironton facility.
