Cleo Diagnostics Limited Directors' report 31 December 2025

Cleo Diagnostics Limited ( ASX:COV ) ( Cleo or the Company ) is bringing to market a simple blood test for the accurate and early diagnosis of ovarian cancer, underpinned by its novel and patented CXCL10 biomarker.

The Company is nearing completion of its FDA enabling pivotal clinical trial in the United States ( U.S. ), with the view to enter first patient market next year. Ultimately, Cleo aims for its technology to be responsible for the screening of women globally.

During the half-year ending 31 December 2025, Cleo advanced key initiatives to commercialise its pre-surgical triage test in the U.S. while laying the groundwork for broader patient markets, including early-stage screening. The Company has delivered notable progress across technology development, manufacturing readiness, clinical trials, market access, and strategic partnerships.

Clinical Trials

• Number of active clinical trial sites increased following the activation of high-volume academic and surgical centres

• A total of 18 trial sites active, including both regional and metropolitan areas to ensure patient diversity in line with FDA requirements

• Continued recruitment for Cleo’s pivotal U.S. clinical trial. The Company is on track to hit its recruitment target of 500 patients in Q1 CY2026.

• Patient recruitment will continue beyond the initial 500 patient target to ensure sufficient usable samples and complete pathology datasets to support analysis.

Manufacturing

• Subsequent to the period-end, Cleo announced the selection of Bio-Techne’s Ella[TM] platform as the immunoassay instrument to deliver its ovarian cancer test

• Ella[TM] platform can deliver materially improved assay sensitivity, precision and automation compared with conventional ELISA platforms.

• 1,100 samples from Hudson Institute of Medical Research.

Regulatory

• Positive feedback received from a second pre-submission meeting with the Food and Drug Administration ( FDA ).

• Successful completion of Stage 1 of the Medical Device Single Audit Program ( MDSAP ), representing a key milestone in the Company’s global regulatory roadmap and ISO 13485:2016 Quality Management System certification pathway.

Commercial activities

• Larger initial total addressable market ( TAM ) established following analysis of insurance data, which identified over ~2 million women per year could benefit from Cleo’s Pre-Surgical Ovarian Cancer Test.

• Health economic study commenced to support Cleo’s market entry, reimbursement and early revenue generation.

• First U.S. Key Opinion Leader ( KOL ) appointed - Dr Nicholas Lambrou, a leading gynaecologic oncologist and surgical specialist.

Auditor’s Responsibility for the Review of the Financial Report

Our responsibility is to express a conclusion on the half-year financial report based on our review. We conducted our review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity , in order to state whether, on the basis of the procedures described, 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 company’s financial position as at 31 December 2025 and 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.
