CHARBONE Confirms a New Delivery of Clean UHP Hydrogen to Ontario, Strengthening its Commercial Deployment in this Strategic Market

Brossard, Quebec, March 19, 2026 – 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 that following the initial delivery on December 22, 2025 to an independent distributor based in Ontario, the Company has made another full load delivery of clean UHP hydrogen to the same customer to support the growth of the Ontario market.

A confirmed ramp-up in commercial activity in Ontario

This new full delivery demonstrates the strength of the established business relationship with this customer and the growing demand for a reliable supply of clean UHP hydrogen in the province of Ontario, supported by CHARBONE.

It also confirms CHARBONE’s ability to ensure efficient and recurring logistics from its Sorel-Tracy production site, while meeting the operational needs of its distribution partners in key markets outside Quebec.

An execution aligned with the regional deployment strategy

Ontario represents a strategic industrial corridor for CHARBONE, particularly due to the concentration of players in the advanced manufacturing, electronics, mobility, and energy sectors. This new delivery is part of the Company’s strategy to:

Establish recurring business relationships with regional distribution partners
Support the development of a local UHP hydrogen supply ecosystem
Prepare for the phased deployment of its future distribution and potential production hubs

Management statement

“The confirmation of this new full delivery to our client in Ontario clearly demonstrates that we are now entering a phase of commercial repeatability and operational execution,” said Dave Gagnon, CHARBONE’s Chief Executive Officer and Chairman of the Board. “Beyond a simple delivery, this is a concrete signal that the Ontario market is gradually adopting a local, reliable, and strategic source of clean UHP hydrogen. CHARBONE is thus positioning itself as a reliable and key partner in structuring this supply chain in North America.”
