Charbone Announces Its First Hydrogen Supply Hub in the Ontario Market

CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) ("CHARBONE" or the "Company"), a North American producer and distributor specializing in clean Ultra High Purity ("UHP") hydrogen and strategic industrial gases, is pleased to announce the development of its first Charbone Hydrogen Supply Hub in the Ontario market, marking a key milestone in the Company’s Canadian expansion strategy.

The Charbone Hydrogen Supply Hub will serve as a dedicated physical storage and local distribution facility, designed to support reliable, on-demand hydrogen supply to industrial, advanced-manufacturing, and mobility customers across Southern Ontario.

Importantly, CHARBONE will use its already existing physical infrastructure for the Hub, including its own hydrogen storage tube assets and other components, enabling the Company to:

• Secure local inventory and buffer capacity
• Control logistics, safety, and high-quality standards
• Reduce dependency on third-party logistics and storage
• Improve supply reliability and response times for customers

This hub-and-spoke model will be another cornerstone of CHARBONE’s strategy to build a scalable network of hydrogen production and supply hubs across Canada and the United States, supporting regional markets with localized storage, logistics, and distribution.

“This first Charbone Hydrogen Supply Hub in Ontario represents a strategic step forward for CHARBONE,” said Dave Gagnon, Chief Executive Officer and Chairman of the Board of CHARBONE. “By investing directly in physical storage assets, we are reinforcing our commitment to local operational control, supply security, and long-term value creation in key industrial markets.”

The Ontario hub is expected to support multiple types of customers and dedicated customer supply programs, with different delivery formats, including tube trailers and micro-bulk solutions. The Ontario hub will be designed to accommodate future storage and production capacity expansions as market demand grows.

CHARBONE views Ontario as a priority market due to its concentration of industrial users, mobility initiatives, and advanced-manufacturing ecosystems, and expects the Hydrogen Supply Hub to play a foundational role in the Company’s broader North American hydrogen logistics platform.
