Announcement PDF Q1 FY27 Quarterly Results 29 October 2026 Presented by: Andre Labuschagne DISCLAIMER This investor presentation has been prepared by Aeris Resources Limited (“Aeris” or the “Company”). By attending an investor presentation or briefing, or accepting, accessing or reviewing this presentation, you acknowledge and agree to the terms set out below. SUMMARY INFORMATION This presentation is for information purposes only and should be read in conjunction with the most recent financial reports and other documents lodged by Aeris with the Australian Securities Exchange (“ASX”) in connection with its continuous disclosure obligations. This presentation does not purport to contain all of the information that an investor should consider when making an investment decision nor does it contain all of the information which would be required in a product disclosure statement or prospectus prepared in accordance with the requirements of the Corporations Act. No reliance should be placed on the information or opinions contained in this presentation, which are provided as at the date of this presentation (unless otherwise stated) and to the maximum extent permitted by law, Aeris has no obligation to update the information contained in this presentation. An investment in securities is subject to known and unknown risks, some of which are beyond the control of Aeris. Investors should consult with their own legal, tax, business and/or financial advisors in connection with any acquisition of securities. FINANCIAL INFORMATION All financial information set out in this presentation is expressed in Australian Dollars unless stated otherwise. Investors should be aware that certain financial measures included in this presentation are “non-IFRS financial information” under ASIC Regulatory Guide 230: “Disclosing non-IFRS financial information” published by ASIC and also “Non-GAAP financial measures” within the meaning of Regulation G under the US Securities Exchange Act of 1934 and are not recognised under the AAS or IFRS. Aeris believes the non-IFRS financial information and non-GAAP financial measures provide useful information to users in measuring the financial performance and condition of Aeris. However, investors should note that the non-IFRS financial information and non-GAAP financial measures do not have standardised meanings prescribed by AAS or IFRS. Therefore, the non-IFRS financial information is not a measure of financial performance, liquidity or value under the IFRS and may not be comparable to similarly titled measures presented by other entities, nor should the information be construed as an alternative to other financial measures determined in accordance with AAS or IFRS. Investors are cautioned, therefore, not to place undue reliance on any non-IFRS financial information included in this presentation. FUTURE PERFORMANCE AND FORWARD-LOOKING STATEMENTS This presentation contains certain ‘forward-looking’ statements, opinions and estimates, which are based on assumptions and contingencies that are subject to change without notice and involve known and unknown risks and uncertainties beyond the control of Aeris and its officers. This includes statements about market and industry trends, which are based on interpretations of current market conditions. Indications of, and guidance on, future earnings and financial position and performance are forward-looking statements. As are statements containing the words “expect”, “anticipate”, “estimate”, “intend”, “believe”, “guidance”, “should”, “could”, “may”, “will”, “predict”, “plan” and other similar expressions. Forward-looking statements are based on information available to Aeris as at the date of this presentation and should not be relied upon as an indication or guarantee of future performance. Except as required by law or regulation (including the ASX Listing Rules), none of Aeris, its representatives or advisers undertakes any obligation to provide any additional or updated information whether as a result of a change in expectations or assumptions, new information, future events or results or otherwise. Investors are strongly cautioned against placing undue reliance on forward-looking statements, especially considering the current economic climate and significant volatility, uncertainty and disruption caused by recent world events such as the COVID-19 pandemic and international hostilities and associated economic changes.
