Half Yearly Report - 31 December 2025
| Kazia Therapeutics Limited Directors’ report 31 December 2025 |
|
The directors present their report, together with the financial statements, on the Consolidated entity (referred to hereafter as the ‘Consolidated entity’) consisting of Kazia Therapeutics Limited (referred to hereafter as the ‘Consolidated entity’ or ‘parent entity’) and the entities it controlled at the end of, or during, the half-year ended 31 December 2025.
Directors
The following persons were directors of Kazia Therapeutics Limited during the whole of the financial year and up to the date of this report, unless otherwise stated:
Dr John Friend
Bryce Carmine
Steven Coffey
Ebru Davidson
Robert Apple
Principal activities
During the financial year the principal continuing activity of the Consolidated entity consisted of pharmaceutical research and development with a view to commercialising the results of our research through license transactions or other means.
Review of operations
The loss for the Consolidated entity after providing for income tax amounted to $12,552,490 (31 December 2024: $10,453,811).
The attached financial statements detail the performance and financial position of the Consolidated entity for the half-year ended 31 December 2025.
Cash resources
At 31 December 2025, the Consolidated entity had total funds of $69,459,980 comprising cash in hand and at bank.
Going concern
For the period ended 31 December 2025 the Consolidated Entity incurred a loss after income tax of $12,552,490 (31 December 2024: $10,453,811), was in a net current asset position of $45,612,689 (30 June 2025 net current liability: $9,119,727) and had net cash outflows from operating activities of $9,540,623 (31 December 2024: $8,420,244) for the half-year ended 31 December 2025.
The Directors note the following with regards to the ability of the Consolidated Entity to continue as a going concern:
| • | During the period, the Company received notifications from Nasdaq regarding non-compliance with the minimum Market Value of Listed Securities requirement. On 18 December 2025, the Nasdaq Office of General Counsel confirmed that the Company had regained compliance with Listing Rule 5550(b) and remained in compliance with all applicable listing standards. Accordingly, the Company’s ADSs continue to trade on The Nasdaq Capital Market. |
| • | The Consolidated Entity continued to access capital markets during the period. Capital raised in the period, including the PIPE entered on 2nd December 2025 which raised US$46.51 million after deducting offering expenses has resulted in a cash balance of AUD 69.46 million at 31 December 2025. The Directors have considered the Consolidated Entity’s cash flow forecasts for a period of at least 12 months from the date of this report, together with available cash and capital-raising mechanisms, and believe that the Group will be able to meet its obligations as and when they fall due. |
Accordingly, the financial statements have been prepared on a going concern basis which assumes continuity of normal activities and the realisation of assets and the settlement of liabilities in the ordinary course of business.

Research and development report
During the reporting period (July 1, 2025 to December 31, 2025), the Consolidated entity advanced paxalisib beyond neuro-oncology into multiple breast cancer translational and clinical settings, including a Company-sponsored Phase 1b study in metastatic triple-negative breast cancer (TNBC), collaborative ex vivo studies in HER2-positive metastatic breast cancer, and expanded-access real-world use. On 10 July 2025, the Company reported preliminary results from the first patient in its Phase 1b paxalisib combination regimen (paxalisib + pembrolizumab + standard chemotherapy) after 21 days of dosing, including a >50% reduction in circulating tumor cells (CTCs) and a notable decrease in CTC clusters.
On 1 August 2025, the Company announced an approximately $2.0 million private placement at a premium to market, with proceeds intended to support continued clinical development of the company’s lead programs, including paxalisib and EVT801.
On 11 September 2025, the Company announced new findings from a collaborative research program led by Professor Sudha Rao at QIMR Berghofer, reporting that paxalisib monotherapy demonstrated a statistically significant reduction in single CTCs and complete (100%) disruption of CTC clusters (>3 cells) in ex vivo blood samples from stage IV HER2-positive metastatic breast cancer patients.
On 2 October 2025, the Company reported an expanded-access case in metastatic TNBC treated with a combination immunotherapy/chemotherapy regimen plus paxalisib, in which imaging after three weeks of treatment demonstrated an 86% reduction in overall tumor burden.
In October 2025, the Company also expanded its immuno-oncology pipeline through an exclusive collaboration and in-licensing agreement with QIMR Berghofer for a first-in-class PD-L1 protein degrader program (lead optimized compound NDL2), intended to address resistance mechanisms not reached by existing checkpoint inhibitors.
On 27 October 2025, the Company announced its intention to request a follow-up FDA Type C meeting to discuss overall survival findings in newly diagnosed glioblastoma patients treated with paxalisib and to seek feedback on a potential regulatory pathway aligned with the FDA Oncology Center of Excellence’s Project FrontRunner initiative.
On 18 November 2025, the Company provided a clinical update describing an initial immune-complete response (iCR) in metastatic TNBC in an expanded-access setting and a broader Q4 business update across breast cancer immuno-oncology and GBM regulatory strategy.
In December 2025, the Company reported additional momentum across both R&D execution and corporate runway. On 2 December 2025, the Company announced the pricing of an approximately $50.0 million private placement of equity securities, with expected net proceeds of approximately $46.5 million after fees and expenses, intended to support continued clinical development programs. On 10 December 2025, the Company announced new data from two presentations at the 2025 San Antonio Breast Cancer Symposium (SABCS), describing mechanistic and early clinical evidence supporting paxalisib activity across HER2-positive metastatic breast cancer and TNBC.
Significant changes in the state of affairs
As noted in the ‘Going concern’ section of this Directors report, the Company entered into two securities purchase agreement with certain established institutional investors for a private placement of equity securities (PIPE).
Apart from this change, there were no other significant changes in the state of affairs of the Consolidated entity during the financial half-year.
Matters subsequent to the end of the financial half-year
No matter or circumstance has arisen since 31 December 2025 that has significantly affected, or may significantly affect the Consolidated entity’s operations, the results of those operations, or the Consolidated entity’s state of affairs in future financial years.

Prefunded and ordinary warrants are measured at fair value through profit or loss. All transactions costs in relation to the warrants are expensed immediately. Changes to the fair value of the instruments post issue will be recognised in profit or loss.
New or amended Accounting Standards and Interpretations adopted
The Consolidated entity has adopted all of the new, revised or amending Accounting Standards and Interpretations issued by the Australian Accounting Standards Board (AASB) that are mandatory for the current reporting period. Any new, revised or amending Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The adoption of these Accounting Standards and Interpretations did not have any significant impact on the financial performance or position of the Consolidated entity.
Going concern
For the period ended 31 December 2025 the Consolidated Entity incurred a loss after income tax of $12,552,490 (31 December 2024: $10,453,811), was in a net current asset position of $45,612,689 (30 June 2025 net current liability: $9,119,727) and had net cash outflows from operating activities of $9,540,623 (31 December 2024: $8,420,244) for the half-year ended 31 December 2025.
The Directors note the following with regards to the ability of the Consolidated Entity to continue as a going concern:
| • | During the period, the Company received notifications from Nasdaq regarding non-compliance with the minimum Market Value of Listed Securities requirement. On 18 December 2025, the Nasdaq Office of General Counsel confirmed that the Company had regained compliance with Listing Rule 5550(b) and remained in compliance with all applicable listing standards. Accordingly, the Company’s ADSs continue to trade on The Nasdaq Capital Market. |
| • | The Consolidated Entity continued to access capital markets during the period. Capital raised in the period, including the PIPE entered on 2nd December 2025 which raised US$46.51 million after deducting offering expenses has resulted in a cash balance of AUD 69.46 million at 31 December 2025. The Directors have considered the Consolidated Entity’s cash flow forecasts for a period of at least 12 months from the date of this report, together with available cash and capital-raising mechanisms, and believe that the Group will be able to meet its obligations as and when they fall due. |
Accordingly, the financial statements have been prepared on a going concern basis which assumes continuity of normal activities and the realisation of assets and the settlement of liabilities in the ordinary course of business.

Note 2. Critical accounting judgements, estimates and assumptions
When preparing the half-year financial statements, management undertakes a number of judgements, estimates and assumptions about recognition and measurement of assets, liabilities, income and expenses. The actual results may differ from the judgements, estimates and assumptions made by management and will seldom equal the estimated results.
The judgments, estimates and assumptions applied in the half-year financial statements, including key sources of estimation uncertainty were the same as those applied in the Consolidated entity’s last annual financial statements for the year ended 30 June 2025.

On 25 July 2025 Maxim Partners LLC exercised a net settlement of warrants and was issued 1,057,000 ordinary shares.
On 31 July 2025 the Consolidated Entity entered into a securities purchase agreement with certain established institutional investors for a private placement of equity securities (PIPE). The net proceeds from the PIPE were US$2,049,992, after deducting offering expenses. Pursuant to the Purchase Agreement, the Consolidated Entity agreed to offer and sell in the Private Placement to such Purchasers (i) 14,204,500 ordinary shares at a purchase price of $0.0176 per Share, and (ii) pre-funded warrants to purchase up to 204,547 American Depositary Shares (“ADSs”), each ADS representing five hundred Ordinary Shares, at a purchase price of $8.7999 per Pre-Funded Warrant. Each Pre-Funded Warrant is exercisable for one ADS at an exercise price of $0.0001 and are exercisable immediately and will expire when exercised in full. The pre-funded Warrants were determined to be classified as a financial liability and a derivative under AASB 132 “Financial Instruments: Presentation” accounted for at fair value through profit and loss because they are denominated in a foreign currency, causing the value to vary with the USD/AUD exchange rate and the Consolidated Entity’s share price, requires a smaller net investment, and is settled at a future date. The initial fair value of the pre-funded Warrants was A$2,600,115.

INDEPENDENT AUDITOR’S REVIEW REPORT
To the members of Kazia Therapeutics Limited
Report on the Half-Year Financial Report
Conclusion
We have reviewed the half-year financial report of Kazia Therapeutics Limited (the Company) and its subsidiaries (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 and the consolidated statement of cash flows for the half-year ended on that date, material accounting policy information and other explanatory information, 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 the Group does not comply with the Corporations Act 2001 including:
| i. | Giving a true and fair view of the Group’s financial position as at 31 December 2025 and of its financial performance for the half-year ended on that date; and |
| ii. | 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. Our responsibilities are further described in the Auditor’s Responsibilities for the Review of the 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 and 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.
We confirm that the independence declaration required by the Corporations Act 2001 which has been given to the directors of the Company, would be the same terms if given to the directors as at the time of this auditor’s review report.

The directors of the Company are responsible for the preparation of the half-year financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the half-year financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error.
BDO Audit Pty Ltd ABN 33 134 022 870 is a member of a national association of independent entities which are all members of BDO International Ltd, a UK company limited by guarantee, and form part of the international BDO network of independent member firms. Liability limited by a scheme approved under Professional Standards Legislation.
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. 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 its financial 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.
