CHARBONE Secures Long-Term Hydrogen Supply Contract with Hone Inc. to Support Clean Energy Solutions for the Entertainment Industry

Varennes, Quebec, June 10, 2026 – CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (“CHARBONE” or the “Company”), a vertically integrated industrial gases company focused on production, distribution and storage of clean ultra-high purity (“UHP”) hydrogen and other strategic industrial gases, is pleased to announce that it has entered into a long-term hydrogen supply contract with Hone Inc. (“Hone”), a provider of mobile hydrogen power solutions for a variety of applications, including the film and television production industry.

Deepening a Proven Commercial Relationship

This agreement follows CHARBONE’s January 22, 2026 announcement of its first hydrogen sales in Ontario to Hone. The long-term supply contract with Hone formalizes and extends that commercial relationship, reflecting the growing acceptance of CHARBONE’s clean hydrogen as a proven energy solution for on-set power generation in one of North America’s most active production markets.

Hone delivers mobile hydrogen power as a clean alternative to diesel generators for film and television productions. Hone’s trailer-mounted 165 kW hydrogen ICE generator systems replicate the standard production 1,400-amp diesel genset that eliminates emissions on-set. Each generator day can displace more than 1.5 tonnes of CO₂ compared to diesel operations. CHARBONE’s hydrogen serves as the fuel source for Hone’s proprietary Fuel Block™ delivery and drop-and-swap refueling system, which enables uninterrupted power throughout production.

Growing Acceptance in the Entertainment Sector

The commercial traction achieved through this partnership demonstrates the real-world viability of hydrogen as a clean, reliable power source in mobile and time-sensitive production environments. A major Hollywood Studio with multiple productions filming in Toronto has utilized Hone’s hydrogen generator service and CHARBONE’s clean hydrogen on several occasions, an important validation of both the technology and the supply chain supporting it.

Contract Terms

The long-term supply agreement is binding in nature and covers a term of two years, subject to the terms and conditions agreed upon by both parties.

Consistent with its established practice, CHARBONE is not disclosing the volume, pricing, or financial terms of this commercial arrangement in order to maintain its competitive position in the market. The Company has noted that demand for its clean UHP hydrogen continues to outpace the available supply, a market dynamic that underscores the strategic importance of expanding CHARBONE’s production network. Revenues generated by the Company’s production, distribution, and service activities are presented on a consolidated basis in its quarterly financial statements.

Management Commentary

“This long-term supply agreement with Hone is a direct extension of the commercial momentum we established earlier this year, and it reflects something meaningful: the entertainment industry is not just testing hydrogen, it is integrating it into active studio production workflows,” said Dave Gagnon, Chairman & Chief Executive Officer of CHARBONE. “Clean hydrogen is proving its value in some of the most demanding operational environments, where reliability, safety, and performance are nonnegotiable. We are proud to be the supply partner enabling that transition, and we look forward to supporting Hone and their clients across what we expect to be a growing number of Hollywood productions.”

“Partnering with CHARBONE on a long-term basis gives Hone the supply certainty we need to confidently serve our clients across multiple Hollywood productions, and a diverse range of other industries and clients” said Ry Smith , CEO of Hone. “Clean, reliable hydrogen is the foundation of our service offering, and CHARBONE’s clean UHP hydrogen meets the quality and logistics standards our customers depend on.”
