Corporation Charbone Renames and Relocates to Support Growth

Brossard, Québec — June 3, 2026 — Leads & Copy — Corporation Charbone, previously known as Corporation Charbone Hydrogène, has officially changed its corporate name to Corporation Charbone and relocated its headquarters to Varennes, Québec. The company, which specializes in vertically integrated industrial gases with a focus on Ultra High Purity (UHP) hydrogen production, distribution, and storage, made these changes to better reflect its evolution into a comprehensive industrial gas platform.

The decision to change the company name was approved by shareholders at the annual and extraordinary general meeting on March 28, 2025. The new name, Corporation Charbone, aims to encompass the company's expanded scope beyond its initial focus on hydrogen production to include a broader range of industrial gases such as oxygen and helium, serving high-growth markets including semiconductors, AI/data centers, advanced pharmaceuticals, aerospace, and defense.

The official name change filing has been completed in accordance with the Quebec Companies Act, and the amended articles of incorporation are available on the company's SEDAR+ profile. The stock symbols for Corporation Charbone on the TSX Venture Exchange (TSXV: CH), the OTCQB market (OTCQB: CHHYF), and the Frankfurt Stock Exchange (FSE: K47) will remain unchanged. The name change is effective June 8, 2026, and the CUSIP number for common shares will be 159916105 (ISIN: CA1599161058). No action is required from current shareholders.

In conjunction with the name change, Corporation Charbone has moved its head office and primary business address to 1645, boulevard Lionel-Boulet, bureau 304, Varennes, Québec J3X 1P7. This strategic location, near its Sorel-Tracy production facility, provides a central point for its expanding industrial gas platform. The new office offers increased space at a more competitive cost per square foot, supporting anticipated workforce growth and operational intensification.

"The officialization of our name to Corporation Charbone is more than just a rebranding; it is a statement of intent," said Dave Gagnon, President and CEO of CHARBONE. "We are no longer solely a hydrogen company. We are building a vertically integrated, multi-molecular industrial gas platform, and the name Corporation Charbone reflects this ambition. Combined with our move to Varennes, which brings us closer to our core operational sites and better positions us for growth, these changes underscore our commitment to realizing our long-term strategic vision of becoming a leading industrial gas platform in North America and beyond."

Furthermore, CHARBONE has renewed its contract with the American investor relations firm RB Milestone Group LLC (RBMG) for another 12-month period, commencing May 20, 2026. RBMG will continue to provide investor relations services, including corporate communications, non-deal roadshow advisory, competitive intelligence, and executive networking. The monthly payment for these services is USD 10,042. RBMG is an independent entity and holds less than 1% of the company's issued and outstanding shares. This agreement is subject to regulatory approval.

Benoit Veilleux, CFO and Corporate Secretary of CHARBONE, commented on the RBMG renewal, stating, "RBMG has been instrumental in helping CHARBONE position its growing industrial gas platform to investors in the United States and internationally. Their strategic guidance and market insights have allowed us to target the right audiences at the right time, while their investor relations support and shareholder reporting have provided valuable insights and enhanced transparency in our development. RBMG's efforts have been crucial in solidifying the foundation for our long-term growth objectives, and we look forward to continuing our collaboration as we embark on the next stage of our expansion."
