CHARBONE Delivers its First Load of Clean UHP Hydrogen in Ontario

- Charbone CORPORATION (TSXV: CH,OTC:CHHYF; 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 successful delivery of the first load of clean UHP hydrogen to an independent distributor based in Ontario, marking the official start of revenue generation for its production division.

First delivery of clean UHP hydrogen to an independent distributor customer in Ontario

As part of its commercial launch, Charbone announces its very first delivery of clean UHP hydrogen produced in Sorel-Tracy, for its independent distribution partner located in Ontario. This initial shipment confirms the Company's ability to efficiently supply markets outside Quebec from the outset.

This contract marks the beginning of a new phase of commercial growth for Charbone, which plans to gradually expand its distribution network and strengthen its presence in the main industrial corridors of Eastern Canada and the American Midwest. Given limited access to consistent and reliable clean UHP hydrogen supply in the North American market and strong demand for the Company's product, Charbone does not disclose purchase order volumes or pricing in order to preserve its competitive position. Revenues from Charbone's production, distribution, and advisory businesses are reported quarterly on a consolidated basis.

"We are extremely proud to begin delivering locally produced clean UHP hydrogen to our first customer today," said Dave Gagnon, Charbone's Chief Executive Officer and Chairman of the Board. "This is another major milestone for Charbone, and also for the clean UHP hydrogen industry in North America."
