Brossard, Quebec, September 5, 2025 – CHARBONE HYDROGEN CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (the “Company” or “CHARBONE”), a company focused on green hydrogen production and distribution, is pleased to announce it has signed, on September 4, 2025, an Asset Purchase Agreement to acquire operational hydrogen production and refuelling equipment in Quebec. The strategic acquisition will enable CHARBONE to fast-track the commissioning of CHARBONE’s flagship Sorel-Tracy facility phase 1 and empower CHARBONE to produce and deliver first industrial high purity hydrogen (UHP) sales in the upcoming quarter.

The equipment, currently in use will be dismantled, repurposed and relocated to Sorel-Tracy.

This transaction follows CHARBONE’s signing of a non-dilutive USD 50 million construction capital facility announced on May 1 and June 4, 2025. While this facility is earmarked for broader project financing rather than this equipment purchase, it demonstrates CHARBONE’s strengthened capital position and ability to scale up its overall development plan.

Key Investor Highlights

Accelerated Timeline: Repurposing proven operating equipment reduces installation costs of new equipment

Selection Process: CHARBONE has been selected as the buyer of the equipment as the seller has accepted $1M in CHARBONE stock as part of a portion of the purchase price at an issue price equal to the market price of CHARBONE’s shares on the TSX Venture Exchange on the effective date plus a cash balance payable in 3 tranches payment, with one-third payment on the effective date and the remaining paid over two years — preserving cash for growth.

Operational Progress: Grid connection is completed; Hydro-Québec installed the energy meter on July 22, and completed the interconnection on August 13, while the Town of Sorel-Tracy completed the water connection to its main system, providing the site with the two elements needed for hydrogen production.

Private Placement Details

Additionally, CHARBONE is pleased to announce the sequential closings of its $1M non-brokered private placement (the “Equity Offering”). The Company has already secured $0.5 million to accelerate the completion of its flagship green hydrogen production facility in Sorel-Tracy, Quebec.

 The initial tranche involved the issuance of 7,699,666 units. A second tranche for the remaining $0.5M is expected to close by October 15, 2025.

 The proceeds from the Equity Offering will be primarily allocated to the Company’s purchase of the operating hydrogen equipment, re-installation at the Sorel-Tracy site, and infrastructure development, and general working capital requirements.  Each of the units offered (each a “Unit”), priced at $0.06 per Unit, included one common share of the Company (each, a “Unit Share”) and one common share purchase warrant (each, a “Warrant”). Each Warrant gives the holder the right to buy one additional common share of the Company at an exercise price of $0.08 for 24 months after the closing date of the Offering (the “Closing Date”). At the Closing Date, the Company paid a finder’s fee of $17,222 and issued 287,040 finder’s warrants to registered dealers related to the sale of certain Units to qualified subscribers introduced by such dealers. The Units were offered under the “accredited investor” exemptions of National Instrument 45-106 – Prospectus Exemptions (in Québec, Regulation 45-106 – Prospectus Exemptions). However, the Company reserves the right to decline subscription amounts below $5,000 (83,333 Units) to avoid excessive administrative costs.  The closing of the Equity Offering remains subject to the approval of the TSX Venture Exchange and other customary closing conditions. The Company may close a second tranche in the coming days, but no later than October 15, 2025. All securities issued under the Offering are subject to a statutory four-month and one-day hold period in Canada following the Closing Date.  This news release does not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of securities in any jurisdiction where such offer, solicitation, or sale would be unlawful, including in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the “1933 Act”) or any applicable state securities laws and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. Persons (as defined in Regulation S under the 1933 Act) unless registered under the 1933 Act and relevant state laws, or if an exemption from registration is available.

CEO Comment

“Investors have waited for Sorel-Tracy to move from development to revenue,” said Dave Gagnon, President and CEO of CHARBONE. “By repurposing proven equipment — at a lower cost of a new build — and structuring the deal to preserve cash, we’re entering execution mode with strong capital backing and minimal dilution. He continues; This acquisition positions us to deliver green and high purity hydrogen (UHP) to our industrial customers quicker, and with best-in-class operating equipment.”

Why This Matters

This acquisition signals a turning point for CHARBONE: after years of development, the company is positioned to deliver its first hydrogen revenues, leverage non-dilutive capital to scale, and capture early-mover advantages in the North American green hydrogen market.

In return, it will diversify and increase its revenue stream through a collaborative approach that will be replicated with other partners and countries in the region, benefiting its shareholders who have been strong supporters of the CHARBONE model for years.

The Collaborative Agreement will provide CHARBONE with a single one-time fee that can be paid in cash or invested in the project. CHARBONE is currently negotiating similar agreements and arrangements with other partners in different regions of the globe.

“This agreement recognized all the efforts that CHARBONE has deployed over the last five (5) years to create a sustainable ecosystem model that works in the real world and not only in the North American market,” said Dave Gagnon, President and CEO of Charbone. He continued, “when you look at the current hydrogen market, you do realize that the two most promising markets are North America and Asia-Pacific, which we are starting now.”

“We are delighted to formalize this strategic collaboration with CHARBONE. Their proven modular and decentralized approach aligns perfectly with our vision to accelerate the adoption of green hydrogen in Malaysia and the wider Asia-Pacific region.

Brossard, Quebec, June 3, 2025 – CHARBONE HYDROGEN CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (the “Company” or “CHARBONE”), North America’s only publicly traded pure-play company focused on green hydrogen production and distribution, is pleased to announce the closing of Units for debt settlements amounting to $1,342,687.

The Company has settled with certain arm’s length suppliers $1,342,687 of payables through the issuance of units. Each unit offered, priced at $0.075 per Unit, comprised one common share of the Company and one common share purchase warrant. Each Warrant will entitle the holder thereof to purchase one additional common share of the Company at an exercise price of $0.10 for 12 months following the closing date. A total of 17,902,489 Units will be issued pursuant to the closing, at a conversion price per unit of $0.075. The Company believes that the settlement of the payables through the issuance of securities is appropriate to advance towards production for its Sorel-Tracy project and the overall need to manage its cash prudently. A formal agreement will reflect any debt settlement and will be subject to the approval of the TSX Venture Exchange. Any securities issued pursuant to a debt settlement will be subject to a statutory four-month hold period in Canada.
