DIAGNAMED HOLDINGS CORP. ANNOUNCES PROPOSED NAME CHANGE TO GEOHYDROGEN CORP., ALIGNING ITS CORPORATE IDENTITY WITH ITS STRATEGIC FOCUS ON NATURAL CLEAN HYDROGEN

Diagnamed Holdings Corp. intends, subject to regulatory acceptance, to change its corporate name to GeoHydrogen Corp., to better align the company's corporate identity with its strategic focus on natural clean hydrogen exploration and development. Natural clean hydrogen -- naturally occurring hydrogen generated within the Earth's crust -- is emerging as one of the most compelling frontiers in the global clean energy transition. Unlike manufactured grey or blue hydrogen, geologic hydrogen is a low-carbon, naturally replenishing resource that requires no energy-intensive production, offering the potential for abundant, low-cost clean energy.

Over the past year, the company has assembled a focused portfolio of highly prospective natural hydrogen projects in two of Canada's most promising jurisdictions: the Temiskaming natural hydrogen project in Ontario, where soil-gas exploration has identified an approximately 11-kilometre corridor of anomalous hydrogen readings, including concentrations exceeding 2,000 parts per million, and the newly acquired Colchester East natural hydrogen project in Nova Scotia, comprising 30 exploration licences totalling 2,104 mineral claims within the prospective Cumberland basin. With its business focused exclusively on natural clean hydrogen exploration and development, the company believes its corporate identity should more accurately reflect its strategic direction and long-term mission.

A name built for the mission: GeoHydrogen Corp.

Accordingly, the company intends to change its corporate name to GeoHydrogen Corp. The proposed name communicates the company's exclusive focus on geologic -- or naturally occurring -- hydrogen, giving investors, partners and stakeholders an immediate and accurate understanding of its mission, its assets and the category in which it operates. In connection with the change, the company's common shares are expected, subject to Canadian Securities Exchange acceptance, to trade on the Canadian Securities Exchange under the proposed ticker symbol GEOH. The company's U.S. OTCQB symbol will be updated in due course. The name change remains subject to CSE acceptance and applicable corporate approvals.

Management commentary

"Our transformation into a focused natural clean hydrogen developer deserves a name that reflects exactly who we are," said John Karagiannidis, chief executive officer. "We believe GeoHydrogen captures both the science and the promise of our work -- identifying naturally occurring, clean hydrogen systems within the earth. As we continue to advance our portfolio in Ontario and Nova Scotia alongside QIMC, we believe this new identity better positions the company to communicate our strategy and build long-term shareholder value."

Continued strategic partnership with Quebec Innovative Materials Corp.

The company also reaffirms its continuing strategic technical advisory partnership with Quebec Innovative, which will continue to guide exploration across both of the company's Ontario and Nova Scotia projects. Quebec Innovative is recognized as one of North America's leading natural hydrogen exploration companies, technical adviser in natural hydrogen and a continental leader in the field, having assembled one of the most advanced natural hydrogen exploration data sets on the continent.

Through its proprietary R2G2 (reactivated rift and graben geostructure) exploration framework, Quebec Innovative integrates structural geology, soil-gas geochemistry, geophysics and proprietary targeting models to identify naturally occurring hydrogen systems. Quebec Innovative has applied these methodologies across multiple sedimentary basins -- including Quebec, Ontario, Nova Scotia and Minnesota -- making it the ideal technical partner as the company advances its portfolio from regional reconnaissance toward defined drill targets.

Quebec Innovative's advisory services to the company include exploration planning, field program supervision, soil-gas sampling, geoscientific interpretation, structural analysis, and the integration of geological and geochemical data sets to support drill target generation across both projects.

What the name change means for shareholders:

• The name change does not affect the number of common shares outstanding.
• Share certificates need not be exchanged. Existing certificates remain valid.
• Following the effective date, shares will trade under the new CSE symbol GEOH and under a new Cusip number, to be announced upon completion.
• The change remains subject to acceptance by the Canadian Securities Exchange and completion of applicable corporate steps, including shareholder approval.

The road ahead

With a clear identity and a defined portfolio in place, the company is focused on execution. Working alongside Quebec Innovative, the company expects a steady flow of exploration catalysts through the current field season -- including infill soil-gas results from the Temiskaming corridor in Ontario and the first systematic geochemical data set from Colchester East in Nova Scotia -- as it advances both projects toward the delineation of priority drill targets.

"The proposed name change to GeoHydrogen marks the beginning, alongside QIMC, of our most active exploration period yet," added Mr. Karagiannidis, chief executive officer. "We look forward to sharing meaningful results in the months ahead as we work to turn Canada's natural hydrogen potential into defined, drill-ready targets."
