4 Quarterly Report June 2026 ALTECH – SALE OF MECKERING LAND Altech advises that settlement has concluded in relation to the sale of Altech Meckering Pty Ltd’s land held in Meckering Western Australia. Gross proceeds of $950,000 were received. The land was deemed a non-core asset by the Board of Directors, with proceeds providing working capital for the group. Altech has retained the rights to M70/1334 and as part of the sale, has entered into an Exploration, Mining, Access, Compensation and Option to Purchase Agreement (“Agreement”) in relation to the mining lease. The Agreement is on terms and conditions considered industry standard in relation to these types of agreements. Importantly, any future mining of the mining lease will be able to continue pursuant to the Agreement, and if the mining lease is sold, any future owner will be able to operate a mining operation pursuant to the Agreement. The land had a mortgage held by major shareholder Deutsche Balaton AG. As part of the sale, Deutsche Balaton AG discharged the mortgage and in return, was granted a bank Guarantee by Altech over a bank account held by Altech in the amount of $500,000. The Guarantee provides Deutsche Balaton AG security in relation to the €2,000,000 bearer bonds that Altech owes to Deutsche Balaton AG. The bearer bonds are due for repayment on 31 October 2026. Altech is endeavoring to sell its land held in Johor, Malaysia in order to repay the bearer bonds. Should the bearer bonds not be repaid by the due date, Deutsche Balaton AG has the right, pursuant to the Guarantee, to call on the $500,000 as partial repayment of the bearer bonds. Should Altech repay the bearer bonds in full by 31 October 2026, Deutsche Balaton AG will be obliged to withdraw and cancel the Guarantee.

5 Quarterly Report June 2026 ALTECH - SILUMINA ANODESTM BATTERY MATERIALS PROJECT DISCONTINUED Altech announced that it had made the decision to discontinue its Silumina AnodesTM project located in Saxony, Germany. The new Board of Directors, appointed in December 2025, assessed the project in detail and having gone through a partner search program with some intense discussions that did not lead to getting the sought after strategic funding partner. The Board determined the likelihood of the project being successful and justifying the operating costs involved in progressing further, it is unlikely that the project will provide any benefits to shareholders. Altech Industries Germany GmbH (“AIG”), the holder of all of the assets in relation to the Silumina AnodesTM project, was placed into liquidation on 30 June 2026 with assets monetised and net proceeds from liquidation to be passed back to Altech Batteries Ltd as 100% shareholder. AIG owns land in Germany, whereby as part of the liquidation process, the land will be sold back to the local government, with gross proceeds of €389K to be received by AIG. In addition, the pilot plant as well as the R&D laboratory equipment held by AIG will be liquidated, with AIG endeavouring to receive maximum proceeds from this process. The liquidation of AIG will provide cost reductions to the Company. Altech is fully focused on commercialisation of its CERENERGY® battery project with advanced discussions with potential joint venture partners continuing. All funds will now be allocated in line with this strategy.
