Brossard, Quebec, April 21, 2026 - TheNewswire – 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, today announced a positive strategic update following its recent executive mission to Malaysia.

The mission was led by Dave B. Gagnon, Chairman and Chief Executive Officer, alongside Patrick Cuddihy, Senior Vice President, and builds on the previously announced framework agreement dated June 25, 2025 with Green Hydrogen ASIAPAC SDN BHD.

Following a series of high-level meetings with Malaysian stakeholders, government representatives, and industrial partners, CHARBONE confirms:

• aligned intent between all parties to advance the Malaysian green hydrogen UHP project; 

• CHARBONE’s interest in taking an equity participation in Green Hydrogen ASIAPAC SDN BHD; 

• CHARBONE’s intention to play an active operational role in the development and execution of the project. 

This milestone reinforces CHARBONE’s strategy to expand beyond North America and establish a disciplined, scalable presence in the Asia-Pacific market, one of the fastest-growing regions for clean hydrogen and specialty gases.

Strengthening Canada–Malaysia Industrial Collaboration

CHARBONE expresses its sincere appreciation to Malaysian authorities and partners for the quality of engagement and strong institutional support throughout the mission.

The Company would like to specifically acknowledge the Malaysian Industry-Government Group for High Technology (MIGHT) for its leadership in:

• facilitating strategic dialogue; 

• supporting cross-border industrial collaboration; 

• enabling meaningful engagement between Canadian and Malaysian stakeholders. 

Malaysia continues to demonstrate a compelling platform for clean energy deployment, supported by national decarbonization initiatives, industrial demand growth, and a strategic geographic position within Asia-Pacific.

Executing CHARBONE’s Global Industrial Gas Platform Strategy

CHARBONE’s expansion into Malaysia aligns with its broader strategy to build a globally integrated industrial gas platform, anchored in:

• ultra-high purity hydrogen (UHP H₂); 

• strategic specialty gases; 

• disciplined project execution through modular, decentralized production models. 

The Company intends to replicate its North American approach in Asia-Pacific, targeting high-growth sectors including:

• semiconductors and advanced electronics; 

• artificial intelligence and data centers; 

• pharmaceuticals and biotechnology; 

• defense and aerospace. 

“Our mission in Malaysia confirms that CHARBONE’s international strategy is gaining real traction. Asia-Pacific represents a critical growth pillar alongside North America, and we are seeing strong alignment with partners who recognize the value of our modular, execution-focused approach,” said Dave Gagnon, CHARBONE’s Chief Executive Officer and Chairman of the Board. “We are particularly encouraged by the opportunity to deepen our involvement with Green Hydrogen ASIAPAC, not only as a technical partner, but as an investor and operator. We thank MIGHT, Malaysian authorities, and our partners for their trust and commitment as we move forward together.”

CHARBONE is currently working with all parties involved to update the continuity and implementation of the current agreement previously signed with the Malaysian group and looks forward to providing our shareholders with more detailed information on the project and development scope.
