TH E W I N N I N G TH E M E S Why REEcycle — Five Things Investors Need to Know 1. Fully domestic & Scalable platform Domestic feedstock → domestic processing → domestic rare earth oxides. A complete U.S. circular loop independent from U.S. adversaries 2. Fastest & most economical path to supply Commercial plant in ~18 months on REEcycle technology & ~$40M capex — versus 7 – 10 years, billions of dollars and permitting risk for new mines ¹ 4. Backed by the U.S. Government A $5.1M U.S. Department of War Production Act award — a targeted commitment to REEcycle 2 5. Recycling - first, then integrate A capital - efficient recycling beachhead and the foundation for a vertically integrated U.S. mine - to - processing platform The bottom line The most advanced domestic rare earth recycler approaching the public markets, with technology proven at commercial scale 3.

Dr Mair has in - depth knowledge of the REE processing methodologies, through both research and feasibility and development oversight of the world - class Kvanefjeld REE Project in Greenland . • Validated by independent laboratories; Pilot plant first operated in 2022 and relocated to larger site in Oklahoma to accommodate scale up CONFIDENTIAL | 13 HCAC Business Combination with REEcycle “Building America’s domestic rare earth supply chain”

SE C T I O N 3 The Opportunity TM (NASDAQ: HCAC)

W HY N O W Rare Earths Are a National Security Priority The strategic problem • Neodymium, praseodymium, dysprosium and terbium are the core of high - performance permanent magnets — powering EV motors, precision - guided munitions, wind turbines, and advanced radar and sonar • The U . S . sources the overwhelming majority of separated and refined rare earths from China — a dependency repeatedly flagged as a critical national security vulnerability • Heavy rare earths Dy and Tb — together ~40% of basket value — have been under Chinese export controls since April 2025 1 • REE demand is forecast to nearly triple by 2035 while Chinese - dominated supply falls short, widening a structural deficit 2 Recycling is believed to be the only near - term domestic fix Recovering REEs from end - of - life NdFeB magnets — in discarded drives, decommissioned defense gear, EV motors and industrial machinery — closes the loop with a domestic circular supply chain that is faster, lower - capex and entirely U.S. - controlled. REEcycle closes the loop on the materials modern defense and clean - energy systems depend on.
