Half Yearly Review of Operations – 31 December 2025
Operations Summary
During the half-year ended 31 December 2025, Alterity Therapeutics made substantial progress in advancing its lead asset, ATH434, toward late-stage clinical development for the treatment of Multiple System Atrophy (MSA), while continuing to strengthen its regulatory, scientific, and corporate foundations.
The Company built on the positive results from its Phase 2 clinical program, first reported in January 2025, with additional analyses strengthening confidence in ATH434’s potential as a disease-modifying therapy in MSA, a rare and devastating neurodegenerative disorder. The new analyses demonstrated robust efficacy at both dose levels studied in Phase 2 and further supported the favourable safety profile of ATH434 across both early and more advanced stages of disease.
Alterity also progressed its regulatory strategy during the period, focusing on preparations for a planned End-of-Phase-2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA), targeted for mid-2026. Activities during the half-year included the generation and integration of clinical, non-clinical and chemistry, manufacturing and controls (CMC) data to support regulatory engagement and Phase 3 trial planning.
In parallel, the Company expanded its scientific and clinical engagement through multiple international conference presentations and advisory meetings with leading experts in movement disorders and autonomic nervous system disorders. These activities provided important peer review of the Phase 2 data and will inform elements of Phase 3 trial design, including patient selection criteria, endpoints and operational considerations.
An important element of advancing into Phase 3 is garnering a better understanding of the potential market size for ATH434 in MSA, if approved. During the period, an independent commercial assessment was completed that indicated a potential worldwide peak sales opportunity of approximately US$2.4 billion, providing a strong commercial rationale for advancing the program into late-stage development.
Alterity also broadened strategic and partnering discussions with pharmaceutical companies and advisers, reflecting continued external interest in ATH434’s differentiated clinical profile, orphan disease and Fast track designations and independently assessed commercial potential.
Governance and leadership enhancements during the period further strengthened the Company’s ability to execute on its late-stage development strategy and engage effectively with regulatory authorities, investors and potential partners.

Clinical Development
ATH434 Phase 2 Clinical Program in MSA
Discovered internally, Alterity’s lead compound ATH434 is an oral agent designed to inhibit the pathologic aggregation of vital proteins in the central nervous system. ATH434 acts to chaperone excess iron in the brain, reducing the toxic accumulation of the α-synuclein protein, and rescuing neuronal function. As an iron chaperone, ATH434 has the potential to address the underlying pathology of the disease and preserve function in individuals with neurodegenerative diseases.
Based on accumulated pre-clinical data and an understanding of the pathology of Parkinsonian disorders and other neurodegenerative diseases, the Company believes ATH434 has excellent potential to treat MSA, Parkinson’s disease as well as Friedreich ataxia.
During the reporting period, Alterity continued to disseminate and present additional analyses from its Phase 2 clinical program evaluating ATH434 in patients with MSA. This program included the ATH434-201 randomised, double-blind, placebo-controlled study and the ATH434-202 open-label study in individuals with more advanced disease than those in the 201 trial.
Additional analyses from the ATH434-201 study reinforced that the efficacy observed at both dose levels was clinically meaningful. Patients receiving ATH434 had slowing of disease progression relative to placebo on the MSA rating scale which assesses activities of daily living (UMSARS I). Importantly, the magnitude of this effect exceeded the threshold considered to represent a clinically meaningful difference. Several secondary endpoints, including the clinical global impression of severity and outpatient activity levels assessed with digital biomarkers, reinforced the findings on the UMSARS I scale.
Importantly, ATH434 also demonstrated a beneficial effect on orthostatic hypotension symptoms as assessed by a patient-reported outcome measure called the Orthostatic hypotension symptom assessment (OHSA). Orthostatic hypotension, which is a core symptom of MSA, is the sustained drop in blood pressure when moving from a sitting to a standing position. On average, placebo-treated participants worsened by approximately six points over 52 weeks on the OHSA whereas participants in both active treatment groups remained stable over the same period. Given the importance of orthostatic hypotension in restricting activity and impairing daily functioning, this is a noteworthy finding observed in Phase 2. Baseline severity of orthostatic hypotension was identified as a key factor affecting efficacy in Phase 2 – an observation that will inform the design of the Phase 3 study.
In parallel, findings from the ATH434-202 open-label Phase 2 study in more advanced MSA demonstrated that treatment with ATH434 produced efficacy outcomes comparable to those observed in earlier-stage patients who received the same dose in the ATH434-201 double-blind study. Key findings included similar changes in UMSARS Part I scores and brain volume in MSA affected areas. The safety profile observed in ATH434-202 was similar to the double-blind study and most adverse events were consistent with the underlying disease.
Collectively, the Phase 2 program supports ATH434’s favourable safety profile and its potential utility in addressing the underlying pathology of MSA across a spectrum of disease severity.

Scientific Engagement and Publications
During the half-year, Alterity continued to actively disseminate data from the ATH434 program and related biomarker work through major scientific forums, supporting external scientific engagement and ongoing Phase 3 planning.
In July 2025, Alterity and academic collaborators published a peer-reviewed manuscript in Annals of Clinical and Translational Neurology titled “The MSA Atrophy Index (MSA-AI): An Imaging Marker for Diagnosis and Clinical Progression in Multiple System Atrophy.” The publication describes a composite MRI-based volumetric measure developed using data from the bioMUSE natural history study, showing that MSA-AI differentiated MSA from related synucleinopathies and correlated with baseline clinical severity and longitudinal disease progression over 12 months. These findings support its potential utility as an imaging biomarker for diagnosing and tracking MSA.
American Neurological Association 2025 Annual Meeting (September 2025):
A poster titled “ATH434 Slows Disease Progression in a Phase 2 Study in Multiple System Atrophy” summarised efficacy and safety findings from the ATH434-201 Phase 2 study highlighting treatment effects on clinical measures of disease progression, patient-reported outcomes and imaging-based biomarkers of brain iron accumulation. The data indicated clinically meaningful effects across multiple endpoints and supported further investigation of targeting excess labile iron as a therapeutic approach in MSA.
International Congress of Parkinson's Disease and Movement Disorders (October 2025):
Alterity delivered multiple presentations featuring additional analyses from the Phase 2 program, including:
“Differences Between Clinical and Imaging Phenotypes in Phase 2 Study of ATH434 in Multiple System Atrophy”; “Relationship Between Alpha-Synuclein Aggregation Profiles, Imaging Biomarkers, and Disease Severity in a Phase 2 Study of ATH434 in MSA”; and “ATH434 Slowed Disease Progression in a Phase 2 Study in Multiple System Atrophy”. These presentations explored the relationship between baseline disease characteristics, including autonomic dysfunction and imaging phenotypes, and clinical outcomes, as well as associations between alpha-synuclein aggregation profiles, imaging biomarkers and disease severity. Collectively, the presentations provided further insight into factors influencing treatment response and highlighted the value of biomarker-informed approaches in the evaluation and interpretation of clinical trial outcomes in MSA.
36th International Symposium on the Autonomic Nervous System (American Autonomic Society) (November 2025):
Dr Daniel Claassen of Vanderbilt University, a key clinical collaborator, delivered an oral presentation titled “Efficacy of ATH434 in Multiple System Atrophy Is Affected by Baseline Disease Characteristics”. The presentation highlighted favourable clinical outcomes from the Phase 2 program and demonstrated that accounting for baseline autonomic dysfunction, including severity of orthostatic hypotension, helped clarify treatment-related signals in patients with MSA. These findings reinforced the importance of phenotype-informed analyses in evaluating therapeutic effects in this patient population.
Society for Neuroscience (SFN) Annual Meeting (November 2025)
A poster titled “The novel antioxidant iron chaperone ATH434 suppresses heme-induced oxidative stress in glutamatergic HT22 neurons” described ATH434’s neuroprotective activities in a heme-induced oxidative injury model in neuronal cells.
Collectively, these scientific engagements advanced external awareness of Alterity’s biomarker-guided approach to MSA clinical development and supported continued refinement of the Company’s late-stage clinical and regulatory strategy.

Corporate and Strategic Activities
Alterity continues to broaden strategic and partnering discussions with pharmaceutical companies and advisers regarding potential collaboration and non-dilutive funding opportunities to support Phase 3 development. These discussions reflect growing industry interest in ATH434’s clinical profile, orphan disease status and independently assessed commercial opportunity.
An independent commercial assessment completed during the period indicated a potential worldwide peak sales opportunity of approximately US$2.4 billion for ATH434 in MSA, further supporting the strong commercial rationale for advancing the program into late-stage development. This assessment was based on feedback from 100 U.S. neurologists, both generalists and specialists, and was driven by a strong intent to prescribe, with over 70% of physicians being “extremely likely” or “very likely” to prescribe ATH434 based on its profile.
In November 2025, Alterity strengthened its Board and leadership team to support the Company’s progression toward late-stage clinical development, increased regulatory engagement and expanded strategic activities. Mr Julian Babarczy was appointed Chair of the Board. Mr Babarczy is an experienced company director and investor with more than 20 years’ experience across Australia’s corporate and funds management sectors and brings a strong track record in supporting emerging growth companies through periods of strategic transition, capital management and value realisation.
Dr David Stamler was appointed to the Board as Managing Director, in addition to his role as Chief Executive Officer. Dr Stamler brings deep clinical development and regulatory experience in neurology, including involvement in multiple FDA approvals, and continues to lead Alterity’s clinical, regulatory and strategic execution as the Company advances toward a pivotal Phase 3 program.
Alterity also expanded its senior management team with the appointment of a Head of Investor Relations and Communications and a Head of Corporate Strategy and Operations, reflecting an increased focus on institutional investor engagement, strategic partnering and operational readiness. These appointments are intended to support enhanced external engagement and to strengthen the Company’s capability as it prepares for Phase 3.
Together, these governance and leadership enhancements reinforce Alterity’s organisational framework and position the Company to execute its clinical, regulatory and strategic objectives as it enters the next phase of growth.
On 21st November 2025, Alterity held its Annual General Meeting in Melbourne, Australia.
During the period, Alterity strengthened its balance sheet by raising approximately A$20 million in September 2025 with new investors and current shareholders. The monies support ATH434 regulatory, clinical, and business development activities, as the Company prepares to initiate a Phase 3 program.
Significant changes in the state of affairs
There have been no significant changes in the state of affairs of the Group during the period. As per the details on the Corporate and Strategic Activities section above, Alterity strengthened its balance sheet by raising approximately A$20 million with new investors and current shareholders.

Therefore, they have been excluded from the calculation of diluted loss per share.

R&D tax incentive receivable represents the amount of R&D tax incentive the Group expects to recover.
A 43.5% R&D Tax incentive refundable tax offset is available to eligible small companies with an annual aggregate turnover of less than $20 million. For the half-year ended 31 December 2025, the Group recorded $2,803,428 and $6,731,991 respectively in other income and receivables.
|
(i) |
Classification as trade and other receivables |
Trade receivables and other receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. If collection of the amounts is expected in one year or less they are classified as current assets. If not, they are presented as non-current assets. Trade and other receivables are generally due for settlement within one year and therefore are all classified as current.

11 Related party transactions
During the half-year ended 31 December 2025 the Group paid a total of A$70,514 (excl. GST) in corporate advisory fees to Kemdev Pty Ltd, an associated entity of Mr. Geoffrey Kempler.
There were no other related party transactions other than those related to director and key management personnel remuneration and equity and transactions by the Group and its subsidiaries.
12 Events occurring after the reporting period
No matters or circumstances have arisen since 31 December 2025 that has significantly affected the Group’s operations, results or state of affairs, or may do so in future years.
13 Significant estimates and assumptions
Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that may have a financial impact on the entity and that are believed to be reasonable under the circumstances.
The Company and its two wholly-owned subsidiaries (the “Group”) makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial period are discussed below.
The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period.
(a) Funding position of the Group
The Group has incurred recurring losses since inception, including an operating loss of $9,554,282 for the half year ended 31 December 2025 (half year ended 31 December 2024: $7,173,335) and an operating cash outflow of $10,620,833 for the half year ended 31 December 2025 (half year ended 31 December 2024: $8,359,622 ).
The Group expects to continue incurring losses into the foreseeable future and will need to raise additional capital in the future to continue the long-term development of its planned research and development programs. Cash and cash equivalents on hand as at 31 December 2025 was $49,200,547.
The current level of funds provide sufficient cash on hand to fulfil planned expenditure over the coming year.
As a result, the Directors have prepared the consolidated financial statements on a going concern basis, which contemplates the realisation of assets and the satisfaction of its liabilities in the normal course of business.
In the directors' opinion:
|
(a) |
the interim financial statements and notes set out on pages 8 to 19 are in accordance with the Corporations Act 2001, including: |
|
(i) |
complying with Accounting Standards, the Corporations Regulations 2001 and other mandatory professional reporting requirements, and |
|
(ii) |
giving a true and fair view of the Group's financial position as at 31 December 2025 and of its performance for the half-year ended on that date, and |
|
(b) |
there are reasonable grounds to believe that Alterity Therapeutics Limited will be able to pay its debts as and when they become due and payable. |
This declaration is made in accordance with a resolution of directors.

Preparation of interim financial statements for users in multiple jurisdictions
The Group has prepared the interim financial statements to conform to the requirements and needs of users of the financial statements located in both Australia and the U.S.
For U.S users, the Group has prepared the interim financial statements to conform to the requirements of IAS 34 Interim Financial Reporting. Consistent with U.S. domestic registrants, the Group has labelled the interim financial information “unaudited” because the interim financial information is not subject to an audit by our independent registered public accounting firm. The auditor’s independence declaration and independent auditor’s review report are included within this filing to meet the requirements of Australian laws and regulations and are furnished, not filed, for the purposes of incorporation of the related financial statements in any U.S. registration document.
For Australian users, the Group has prepared the interim financial statements to conform to the requirements of the Corporations Act 2001 and AASB 134 Interim Financial Reporting. A review of the interim financial information has been performed by the Group's independent auditors to meet the requirements of Australian Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity and users should refer to the auditor’s independence declaration and independent auditor’s review report included within this filing.

Independent auditor's review report to the members of Alterity Therapeutics Limited
Report on the half-year financial report
Conclusion
We have reviewed the half-year financial report of Alterity Therapeutics Limited (the Company) and the entities it controlled during the half-year (together the Group), which comprises the consolidated statement of financial position as at 31 December 2025, the consolidated statement of profit or loss and other comprehensive income, the consolidated statement of changes in equity, consolidated statement of cash flows, for the half-year ended on that date, selected explanatory notes and the directors' declaration.
Based on our review, which is not an audit, we have not become aware of any matter that makes us believe that the accompanying half-year financial report of Alterity Therapeutics Limited does not comply with the Corporations Act 2001 including:
|
1. |
giving a true and fair view of the Group's financial position as at 31 December 2025 and of its performance for the half-year ended on that date; |
|
2. |
complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001. |
Basis for conclusion
We conducted our review in accordance with ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity (ASRE 2410). Our responsibilities are further described in the Auditor's responsibilities for the review of the half-year financial report section of our report.
We are independent of the Group in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional & Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to the audit of the annual financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code.

Responsibilities of the directors for the half-year financial report
The directors of the Company are responsible for the preparation of the half-year financial report, in accordance with Australian Accounting Standards and the Corporations Act 2001, including giving a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of the half-year financial report that is free from material misstatement whether due to fraud or error.
Auditor's responsibilities for the review of the half-year financial report
Our responsibility is to express a conclusion on the half-year financial report based on our review. ASRE 2410 requires us to conclude whether we have become aware of any matter that makes us believe that the half-year financial report is not in accordance with the Corporations Act 2001 including giving a true and fair view of the Group's financial position as at 31 December 2025 and of its performance for the half-year ended on that date, and complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001.
A review of a half-year financial report consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Australian Auditing Standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
