Use of proceeds

The convertible loan is a key component of Charbone's broader strategy to scale hydrogen production capacity and expand its industrial gas platform across North America. The proceeds from the $1.5 million drawdown are expected to be used to:

• Accelerate development timelines of the company's clean UHP (ultrahigh-purity) hydrogen production plants;
• Support capital expenditures and equipment deployment;
• Provide general working capital to accelerate near-term growth initiatives.

Benoit Veilleux, chief financial officer and corporate secretary of Charbone, commented: "This drawdown reflects the continued confidence RiverFort has placed in Charbone and our execution to date. The structured, multitranche nature of this facility allows us to access growth capital in a disciplined way, aligned with our operational milestones at Sorel-Tracy and across our industrial gases platform. Importantly, this is not a traditional equity raise, but a convertible loan structure where there is no dilution to shareholders today. Minimizing dilution is always our priority. We look first at non-dilutive and low-dilution structures, including project-level financing, equipment financing and strategic partnerships that are designed to accelerate our growth. We remain focused on delivering value for our shareholders through operational performance. "
