BROSSARD, QUEBEC - March 12, 2026 (NEWMEDIAWIRE) - 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 its participation in the Hydrogen East conference on April 13, 2026, as well as the development of a supply hub dedicated to UHP hydrogen and strategic specialty gases in the Atlantic Canada market (“Atlantic Hub”).

This initiative marks a new step in CHARBONE's deployment strategy aimed at establishing an integrated network of hubs for the production, storage and distribution of hydrogen and strategic industrial gases in North America.

The future Atlantic Hub, which will be managed by its subsidiary CHARBONE Nova Scotia Inc. and operational by June 2026, will serve as a dedicated physical facility for local storage and regional distribution, ensuring a reliable and flexible supply of hydrogen for a variety of demanding industrial users, including the defense, advanced manufacturing, mobility, and energy infrastructure sectors.

CHARBONE has been active in the Atlantic region for over three (3) years and has developed in-depth knowledge of the Nova Scotia, New Brunswick, and Prince Edward Island markets, while working on various initiatives with major potential clients and partners, particularly in the following areas:

- Port infrastructure

- Canadian Navy shipyards and facilities

- Automotive component supply chain

- Utility and energy companies

- Research and development companies

- Advanced zero-emission transportation solutions

This "hub-and-spoke" model is a cornerstone of CHARBONE's strategy to progressively deploy a scalable network of hydrogen and strategic industrial gas supply hubs across Canada and the United States, supporting regional markets through local storage, logistics, and distribution capabilities.

“The Atlantic Canada region represents a strategic market for CHARBONE, particularly due to the presence of high-quality infrastructure, large industrial users, and energy transition initiatives,” said Dave Gagnon, CHARBONE’s Chief Executive Officer and Chairman of the Board. “The Company anticipates that this hub will play a structuring role in the development of its future North American hydrogen logistics platform.”
