BRISBANE, QUEENSLAND, AUSTRALIA – Graphene Manufacturing Group Ltd. (TSX V: GMG) (OTCQX: GMGMF) (“GMG” or the “Company”) is is pleased to announce that the Board of Directors of GMG has approved the investment of an additional AU$1.4 million, which is expected to complete the construction of the Company’s Gen 2.0 Graphene Manufacturing Technology plant (the “Gen 2.0 Plant”) capable of producing 10 tons of graphene per annum. The total capital cost for the Gen 2.0 Plant is an estimated AU$2.3 million, an expenditure that was largely included in the proposed use of proceeds for the March 2025 Bought Deal Financing of C$5,796,000.

The Company’s Board is happy with progress to date and is confident that the Gen 2.0 Plant project is on track to meet its original budget and expectation to be online by the middle of 2026. The early work and procurement of the long lead items is substantially complete, and engineering and design has commenced.

The Gen 2.0 Plant is expected to be largely self-powered from standalone energy generation that utilizes renewable sources, an energy storage system and hydrogen enriched natural gas provided by tail gas power generation.

GMG’s Managing Director and CEO, Craig Nicol, commented: “We are very excited with the progress to date of the Gen 2.0 project and are looking forward to bringing the plant online – on time and on budget.”

GMG’s Chairman and Director, Jack Perkowski, commented: “A successful Gen 2.0 project will form the basis for the Company’s future expansion plans.”

Quarterly Financial Results Update

The Company is pleased to provide a further update to its most recent Quarterly Financial Results as published and filed on March 2, 2026. The Company’s results are reported under International Financial Reporting Standards (IFRS). This news release may include certain Non-IFRS measures as reported in the Company’s Quarterly Management Discussion and Analysis (“MD&A”) that are used internally by management to assess the underlying operational performance of our business.

Understanding the Non-Cash Warrant Liability
As at December 31, 2025, the Company had 18.6 million outstanding share purchase warrants with exercise prices denominated in Canadian dollars. Because GMG’s functional currency is the Australian dollar, IFRS accounting standards require these warrants to be treated as a derivative financial liability and revalued at fair value each reporting period.

During Q2 FY2026, GMG’s share price increased 178%, a strong performance that reflects growing market confidence. However, under IFRS, this share price increase results in a higher calculated fair value for the warrant liability, which in turn generates a non-cash loss in the Company’s statement of profit or loss and a corresponding increase in total liabilities on the balance sheet.

Key Points for Shareholders:
• This accounting adjustment is entirely non-cash and does not affect GMG’s cash position, operations, or business fundamentals.
• The Company’s cash balance at December 31, 2025 was A$13.9 million, up from A$7.7 million at June 30, 2025.
• Excluding the warrant liability, the Company’s underlying net assets position at December 31, 2025 was positive A$21.5 million.
• The warrant liability decreases when warrants are exercised (converting the liability to equity and adding cash), or when the warrants expire or when the share price declines. Subsequent to December 31, 2025, approximately 2.9 million warrants were exercised for gross proceeds of A$3.6 million, further strengthening the Company’s cash position and reducing the warrant liability by a corresponding amount.

Management views the warrant liability as a technical accounting matter that does not reflect the Company’s operational performance or strategic progress. The Company’s market capitalization at December 31, 2025 was approximately USD$200 million.

Non-IFRS Measures
A Non-IFRS measure that the Company refers to in its MD&A is EBITDA, which is revenue before finance costs, tax, depreciation and amortization, and after adjusting for certain non-cash items and other earnings adjustment items. The Company believes that EBITDA provides useful information to assess the operational performance of the business, however, Non-IFRS measures do not have a standardized meaning under IFRS, have not been subject to audit, and should not be considered as an indication of or alternative to an IFRS measure of financial performance.

The following table provides the reconciliation of the underlying loss for the period and adjusted basic diluted loss per share, as adjusted and calculated by the Company. This reconciliation adjusts for the non-cash change in fair value of warrants which is included in the Company’s Unaudited Condensed Consolidated Interim Statement of Profit or Loss and Other Comprehensive Income.

Table 2: Calculation of the unaudited adjusted loss for the period and adjusted basic and diluted loss per share, as adjusted and calculated by the Company.

(1) Due to the loss recognized for the years, all outstanding stock options, warrants, broker warrants, restricted share units and performance share units were excluded from the calculation of diluted loss per share due to their anti-dilutive effect.

(2)Calculated using loss for the period over the weighted average number of ordinary shares as per IFRS.

(3) Calculated using adjusted loss for the period over the weighted average number of ordinary shares (non-IFRS measure).

About GMG:

GMG is an Australian based clean-technology company which develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in house production process. GMG uses its own proprietary production process to decompose natural gas (i.e. methane) into its natural elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, ‘tuneable’ and low/no contaminant graphene suitable for use in clean-technology and other applications.

The Company’s present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications. In the energy savings segment, GMG has initially focused on graphene enhanced heating, ventilation and air conditioning (“HVAC-R”) coating (or energy-saving coating) which is now being marketed into other applications including electronic heat sinks, industrial process plants and data centres. Another product GMG has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.

In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries (“G+AI Batteries”). GMG has also developed a graphene additive slurry that is aimed at improving the performance of lithium-ion batteries.

GMG’s 4 critical business objectives are:

1. Produce Graphene and improve/scale cell production processes
2. Build Revenue from Energy Savings Products
3. Develop Next-Generation Battery
4. Develop Supply Chain, Partners & Project Execution Capability
