About Opthea Ltd

https://opthea.com/

Opthea is a clinical-stage biopharmaceutical company focused on developing novel therapies for vision-threatening retinal diseases, particularly wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME). The company's lead product candidate, sozinibercept, is a first-in-class biologic 'trap' inhibitor targeting Vascular Endothelial Growth Factors C and D (VEGF-C and VEGF-D). Sozinibercept is being developed for administration in combination with standard-of-care anti-VEGF-A therapies. This dual-pathway inhibition aims to deliver superior visual outcomes by more comprehensively blocking the mechanisms that contribute to disease progression, addressing the limitations of current treatments that only target VEGF-A. The therapy is being evaluated in late-stage pivotal clinical trials for wet AMD.

Appendix 4D and Half Year Report for period 31 Dec 2025 30 pages 568.1KB
Interim / Quarterly Report Classification · 100% confidence The document is titled 'Opthea Limited Appendix 4D Half-year report' and covers the half-year ended 31 December 2025. It includes detailed financial data such as profit figures, net tangible assets, directors' report, auditor's review report, condensed consolidated financial statements, and notes. The presence of comprehensive financial statements and management discussion for a half-year period indicates this is a substantive interim financial report. The document length is 15,000 characters, which is consistent with a full interim report rather than a brief announcement. The content includes detailed operating results, strategic review, and financial performance for the half-year period, which aligns with the definition of an Interim / Quarterly Report (IR).

Interim / Quarterly Report Classification · 100% confidence The document is titled 'Quarterly Activity Report Q2 FY26' and includes detailed financial data such as cash flow statements, operating cash inflows/outflows, and other financial metrics for the quarter ended 31 December 2025. It also references compliance with ASX Listing Rule 4.7B and includes an Appendix 4C cash flow report, which is a standard quarterly report for entities listed on the ASX. The document contains substantive financial data and analysis for a period shorter than a full fiscal year, consistent with an interim or quarterly report. It is not merely an announcement of a report or a certification, but a full quarterly financial disclosure. Therefore, the appropriate classification is Interim / Quarterly Report (IR).

Notification of cessation of securities - OPT 4 pages 15.4KB
Regulatory Filings Classification · 95% confidence The document is titled 'Appendix 3H - Notification of cessation of securities' and details the cessation (expiry or lapse) of certain securities (options) issued by Opthea Limited. It includes specific dates of cessation, reasons for cessation, and updated issued capital figures. The document is a formal announcement to the ASX about changes in the company's securities, specifically the cessation of certain options. It does not contain financial statements, management discussion, or detailed financial results. It is not an annual or interim report, nor an earnings release or management report. It is also not a regulatory certification or a proxy statement. The document fits the category of a Regulatory Filing (RNS) as it is a general regulatory announcement about securities cessation that does not fit into more specific categories like share issue or capital change (SHA) or director dealings (DIRS). The document length is about 4951 characters, which is consistent with a detailed regulatory announcement rather than a full report. Therefore, the best classification is Regulatory Filings (RNS).

Change of Director's Interest Notice - KC & LG 7 pages 275.0KB
Director's Dealing Classification · 100% confidence The document is titled 'Appendix 3Y Change of Director’s Interest Notice' and references ASX listing rule 3.19A.2 and section 205G of the Corporations Act. It details changes in securities holdings by company directors, including the number of securities held before and after the change, the nature of the securities, and the nature of the change (e.g., issue of options under a Non-Executive Directors Share and Option Plan). The document is a formal notification of personal share transactions by company directors. It does not contain financial performance data, earnings, or management discussion, nor is it an announcement of a report publication. Therefore, it fits the definition of Director's Dealing (DIRS). The document length (9843 characters) is sufficient to contain detailed information, confirming it is not a mere announcement or certification.
