The Appendix 4E and 2024 digital annual report documents are attached. ENDS Dr. Steven Gourlay CEO & Managing Director P: +61 2 8964 7401 E. steven.gourlay@actinogen.com.au Investors Media Michael Roberts Investor Relations M: +61 423 866 231 George Hazim Media & Public Affairs Australia M: +61 417 516 262 E. michael.roberts@actinogen.com.au E: georgehazim@mediaaffairs.com.au Announcement authorised by the Board of Directors of Actinogen Medical About Actinogen Medical Actinogen Medical (ACW) is an ASX-listed, biotechnology company developing a novel therapy for neurological and neuropsychiatric diseases associated with dysregulated brain cortisol. There is a strong association between cortisol and detrimental changes in the brain, affecting cognitive function, harm to brain cells and long-term cognitive health. Cognitive function means how a person understands, remembers and thinks clearly. Cognitive functions include memory, attention, reasoning, awareness and decision-making. Actinogen is currently developing its lead compound, Xanamem, as a promising new therapy for Alzheimer’s Disease and Depression and hopes to study Fragile X Syndrome and other neurological and psychiatric diseases in the future. Reducing cortisol inside brain cells could have a positive impact in these and many other diseases. The cognitive dysfunction, behavioural abnormalities, and neuropsychological burden associated with these conditions is debilitating for patients, and there is a substantial unmet medical need for new and improved treatments. Current Clinical Trials The XanaCIDD Phase 2a cognition & depression trial is a double-blind, six-week proof-of-concept, placebo-controlled, parallel group design trial in 167 patients. Participants are evenly randomized to receive Xanamem 10 mg once daily or placebo, in some cases in addition to their existing antidepressant therapy, and effects on cognition and depression are assessed. Positive topline results on depression were announced 12 August CY2024 and updated 26 August CY2024. Actinogen Medical Limited ACN 086 778 476 Suite 901, Level 9, 109 Pitt Street, Sydney NSW 2000 +61 2 8964 7401 | actinogen.com.au 1 The XanaMIA Phase 2b Alzheimer’s disease trial is a double-blind, 36-week treatment, placebo-controlled, parallel group design trial in 220 patients with mild to moderate AD and progressive disease, determined by clinical criteria and confirmed by an elevated level of the pTau181 protein biomarker in blood. Patients receive Xanamem 10 mg or placebo, once daily, and effects on cognition, function and progression of Alzheimer’s disease are assessed. Thus, Xanamem is being assessed in this trial for its potential effects as a both a cognitive enhancer and a disease course modifier. Initial results from an interim analysis of the first 100 participants are anticipated in mid 2025. About Xanamem Xanamem’s novel mechanism of action is to block the production of cortisol inside cells through the inhibition of the 11βHSD1 enzyme in the brain. Xanamem is designed to get into the brain after it is absorbed in the intestines upon swallowing. Chronically elevated cortisol is associated with cognitive decline in Alzheimer’s Disease and excess cortisol is known to be toxic to brain cells. Cognitive impairment is also a feature in Depression and many other diseases. Cortisol itself is also associated with depressive symptoms and when targeted via other mechanisms has shown some promise in prior clinical trials. The Company has studied 11β-HSD1 inhibition by Xanamem in more than 300 volunteers and patients, so far finding a statistically significant improvement in working memory and attention, compared with placebo, in healthy, older volunteers in two consecutive trials and clinically significant improvements in functional and cognitive ability in patients with biomarkerpositive mild AD. Previously, high levels of target engagement in the brain with doses as low as 5 mg daily have been demonstrated in a human PET imaging study. A series of Phase 2 studies in multiple diseases is being conducted to further confirm and characterize Xanamem’s therapeutic potential. Xanamem is an investigational product and is not approved for use outside of a clinical trial by the FDA or by any global regulatory authority. Xanamem® is a trademark of Actinogen Medical.

The Company continues to make compelling progress in the execution of its strategy, focusing on “following the science” in the successful development of our novel, small molecule drug Xanamem, to treat illnesses such as Alzheimer’s disease and depression. We continue to believe that Xanamem’s mechanism of “tissue cortisol synthesis inhibition” to reduce excess cortisol inside brain cells has the potential to have a major impact on the lives of patients and their families suffering from many neurological and neuropsychiatric conditions. It was great to witness gradually improving conditions in the biotech market from the start of 2024, especially as key licensing and M&A activity signalled a change in sentiment from the very challenging market headwinds of 2023, particularly in the small-cap biotech sector. A year of achievement The Company enjoyed a productive financial year with the achievement of several major milestones including the execution of two phase 2 trials running concurrently during the second half. It takes significant effort to get a trial to the starting line, let alone manage the complexities of running two sizeable trials across different jurisdictions simultaneously. The XanaCIDD phase 2a depression trial completed its final patient treatment on 1 July 2024, having recruited 167 patients in 16 months – a tremendous effort from Actinogen staff, our collaborators and the participants. An unexpectedly high placebo effect impacted our ability to see a potential Xanamem effect in the cognition primary endpoint. In the targeted secondary endpoint, we were very pleased to see positive benefits on depression, confirming the clinical activity of our 10 mg dose and validating the drug’s mechanism to control brain cortisol. The XanaMIA phase 2b Alzheimer’s disease trial commenced in April 2024 and, typical of early phases in a trial, screening and enrolment is gradually ramping up in Australia and will be aided by the addition of new sites opening in the USA. 8 Actinogen Medical Limited In another highlight, the Company received approval from the UK Medicines and Healthcare products Regulatory Agency of its application for a UK Innovation Passport as part of the Innovative Licensing and Access Pathway (ILAP) for Xanamem in the treatment of Alzheimer’s disease. This UK version of the FDA’s “breakthrough” designation represents a significant independent endorsement by an international regulator of the potential medical importance of the Xanamem program. The team has also continued to work diligently to complete two academic manuscripts that were published in the peerreviewed journal, The Journal of Alzheimer’s Disease in the second half of the financial year, with further academic papers planned. Executive leadership CEO Dr Steven Gourlay has continued to lead the executive team with distinction. He has the relevant experience needed of a biotech CEO for a Company in the mid-late stage of vital clinical development with a view to commercialisation. Steven navigates the big-picture strategy with a clear view and plans for later-stage requirements yet is proactive and attentive to the many details and intricacies of the here and now of drug clinical development. I firmly believe he has the experience and agility to steer through complex situations while balancing our budget in a high-cost industry. Dr Gourlay leads a small but innovative, high calibre executive leadership team with complementary skills that produces results. We added to the team’s skillset this year with the appointment of the Company’s first full-time Chief Financial Officer, Mr Will Souter, who is a first-class CFO with a wealth of biotech, financial and corporate communications experience. Will has taken responsibility for finance, communications, information technology and human resources, and is skilfully leading capital management activities with the CEO. I also commend the hard work and achievements of Ms Cheryl Townsend and her clinical operations team during the past year. I cited earlier the complexities of running two sizeable trials simultaneously across different jurisdictions, including significant pre-trial preparations, and the successful delivery of those responsibilities is due in no small part to Cheryl’s leadership. And I take this opportunity to thank the wider executive leadership team and the Actinogen workforce, as well as key contractors, who all work so diligently to manage a very effective and efficient clinical development program and corporate functions required of a listed biotech. Board, corporate governance and advisory boards The board seeks continuous improvement in its governance and management oversight capability. During the past year we again conducted a review of all activities and responsibilities, including assessing the Board skills matrix to identify gaps and opportunities for improvement. Our significant corporate The Actinogen team has again proven its ability to effectively and efficiently deliver high quality clinical trial programs, with the depression trial successfully concluded and the pivotal Alzheimer’s phase 2b trial well under way as we head into the new financial year. policies and other corporate governance materials are posted on our website, and we maintain a robust corporate governance framework to support the management and execution of our long-term strategy and annual strategic priorities. I thank my fellow board members for their contributions during a productive year which has necessarily required a significant planning agenda for the next stages in the Company’s development. I would especially like to acknowledge the contribution of Dr Nicki Vasquez who joined the board in March 2023 and with her astute insights, has proven to be a valuable contributor to board deliberations. We will continue to assess our corporate board skillsets and, where appropriate, make changes or additions as we did with Dr Vasquez’s appointment. Actinogen continues to utilise world-leading advisors on our advisory boards to help drive our strategic initiatives and ensure the success of our clinical development program. This year we welcomed Dr Steve Targum, a world-renowned psychiatrist as an external advisor and chair of the XanaCIDD trial safety committee. Shareholders may have seen Dr Targum as an external expert commentator on the XanaCIDD results webinar providing valuable input to the understanding of the topline trial results. I thank all our esteemed independent external advisory board and committee members for their important contributions to the success of the Company in FY2024. Further details on the Actinogen corporate board, advisory boards and senior executive personnel can be found on the Company’s website: https://actinogen.com.au/our-team/ Capital management The Company successfully completed two capital raisings totalling $18.9 million during the year and I thank shareholders for your strong support in the 2023 entitlement offer and the recent May 2024 raising, where the entitlement offer was oversubscribed approximately 1.8 times. Additional funding has been received from the conversion of options associated with those two capital raisings. If you have any questions relating to your shareholding in Actinogen, please contact Automic at hello@automicgroup.com.au or on 1300 288 664 (within Australia) or +61 2 9698 5414 (outside Australia). A further $9.0 million related to the 2024 R&D tax incentive rebate is expected to be received in Q4 CY2024. With a cash balance of $9.5 million at 30 June 2024 and the additional funding sources described above, the company and its current programs are funded to late CY2025. Annual General Meeting This year’s Annual General Meeting will be held in Sydney on Thursday 14 November 2024, and we invite shareholders to attend in person. Details of the meeting time and Sydney location will be announced in due course. Outlook Actinogen has again proven its ability to deliver high quality clinical trials in an efficient and effective manner. A key focus in FY2025 will be on planning for follow on activities in our depression trial program following the release of positive topline results for the XanaCIDD phase 2a trial announced earlier this month. This includes deeper analysis of the full results dataset and announcing and publishing additional information where relevant. Plus, we will be undertaking discussions with regulators such as the FDA, EMA and the TGA to identify the optimal trial design as we enter the next phase. We look forward to making further progress in our XanaMIA phase 2b Alzheimer’s disease clinical trial in FY2025 as we activate sites in the USA and ramp up patient screening and enrolments at all locations, ahead of an interim analysis in mid CY2025. The design and enrolment criteria for this phase 2b trial are based on the strong scientific rationale derived from the findings of the biomarker trial, published recently in the peer reviewed Journal of Alzheimer’s Disease, which showed that Xanamem potentially slows disease progression in AD patients with elevated levels of plasma pTau. The board looks forward with confidence to a very exciting 2025 financial year for Actinogen. As always, we remain vigilant in our governance and proactive in our management as we deliver on our strategic priorities. On behalf of the Board, I would like to thank you, our shareholders, for your ongoing support, and we look forward to updating you on our progress during the coming year.

Annual Financial Report 9 Chief Executive Officer’s letter Dr Steven Gourlay, CEO & Managing Director Dear Shareholder, The “rights” for Xanamem: The Xanamem program is now in advanced late-stage clinical development. • Hitting the right target – 11β-HSD1 in the brain Actinogen has now reached a transformational stage in its clinical development of Xanamem, with positive results on depression in our XanaCIDD phase 2a trial. The improvements seen in depression symptoms clearly show that Xanamem’s mechanism of action in the brain to inhibit tissue production of cortisol has major clinical impact. The associated lack of superiority over placebo in short-term cognitive enhancement was surprising but instructive for the depression program. The FDA has long argued that cognitive dysfunction improves as depression improves, although the scientific literature has established that the correlation is by no means universal. Based on our XanaCIDD results, we will be pursuing depression itself, not short-term cognitive enhancement, in future clinical trials – a much more straightforward path with regulators like the FDA, EMA and TGA. In contrast, trials of Xanamem in patients with Alzheimer’s disease will continue to include both functional and cognitive measures in order to adequately describe the potential slowing of disease progression in this confirmatory, late-stage trial. Xanamem is a unique orally administered molecule in its own class as a “brain tissue cortisol synthesis inhibitor”. In fact, the International Non-proprietary Names for Pharmaceutical Substances (INN) of the World Health Organization recognized this by giving its future “generic” or non-proprietary name a unique suffix (name to be announced in early 2025 pending final vetting). No other brain-penetrant modifiers of tissue cortisol synthesis are in development to our knowledge and no other 11β-HSD1 inhibitors have ever received an INN name. So how did we get here and where do we go to from here? As we have explained before, the science of clinical deve
