Operating Review

During the half-year ended 31 December 2025, the Company continued to focus on reviewing the strategic and technical direction of the Company following the completion of its 20nm Sixth Platform Lot development program, while implementing measures to preserve capital and maintain governance stability.

Strategic and Technical Review

On 18 August 2025, the Company announced the completion of a comprehensive root cause analysis of the 20nm Sixth Platform Lot, utilising both physical and chemical analytical techniques. The analysis confirmed that etch residues introduced during manufacturing resulted in electrical shorting of the memory devices. Following receipt of these findings, the Company commenced an evaluation of the most effective strategic and technical development pathways for its technology going forward.

As part of this review, and following extensive discussions with its development partners, the Company announced on 5 September 2025 its decision to disengage from its collaborations with imec and Infineon Technologies LLC. This decision was taken to preserve resources while the Board undertook a broader strategic review to ensure that any future development activities align with the Company’s longterm commercialisation objectives.

The strategic review, formally initiated in September 2025, remains ongoing and is focused on stabilising the business, preserving capital, and assessing a range of potential value-accretive pathways. These include opportunities both within and adjacent to the Company’s existing technology base, including areas aligned with AI-enablement, where demand for faster, denser and more energy-efficient computing architectures continues to accelerate.

During the period, the Company engaged in preliminary and confidential discussions with parties operating in aligned fields. These discussions remain exploratory in nature and no binding agreements or commitments had been entered into as at 31 December 2025.

4DS Memory Limited Notes to the condensed consolidated financial statements 31 December 2025

Note 1. General Information

Statement of compliance

The half-year financial statements are general purpose financial statements prepared in accordance with Australian Accounting Standard AASB 134 ' Interim Financial Reporting ' and the Corporations Act 2001 . Compliance with AASB 134 ensures compliance with International Financial Reporting Standard IAS 34 ' Interim Financial Reporting '. The half-year financial statements do not include all the notes of the type normally included in annual financial statements. Accordingly, these financial statements are to be read in conjunction with the annual report for the year ended 30 June 2025 and any public announcements made by the Company during the interim reporting period in accordance with the continuous disclosure requirements of the Corporations Act 2001 .

Basis of preparation

The condensed consolidated financial statements have been prepared on the basis of historical cost, except for the revaluation of certain non-current assets and financial instruments. Cost is based on the fair values of the consideration given in exchange for assets. All amounts are presented in Australian dollars, unless otherwise noted.

The accounting policies and methods computation adopted in the preparation of the half-year financial statements are consistent those adopted and disclosed in the Company's annual financial report for the financial year 30 June 2025 except as discussed in note 2 Adoption of new and revised Australian Accounting Standards . The accounting policies are consistent with Australian Accounting Standards and with IFRS.

Going Concern

The consolidated financial statements have been prepared on going concern basis. In arriving at this position, the directors have had regard to the fact that the Company has, or in the directors’ opinion will have access to, sufficient cash to fund administrative and other committed expenditure for a period of not less than 12 months from the date of this report.

As at 31 December 2025, the net assets of the Group totalled $7,650,006 (30 June 2025: $8,781,430) and cash on hand totalled $3,342,999 (30 June 2025: $10,198,573) and short term investments of $5,450,000(30 June 2025: $nil) .

Estimates and judgements

When preparing the interim 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 to the estimated results.

The judgements, estimates and assumptions applied in the interim financial statements, including the key sources of estimation uncertainty, were the same as those applied in the Group’s last annual financial statements for the year ended 30 June 2025 except that the management has changed the judgment to disclose the term deposits with original maturities exceeding three months as financial investments rather than cash equivalents.

As a result of this reassessment, these deposits are now presented as financial investments , rather than cash and cash equivalents . This change reflects management’s updated view that such deposits are held for investment purposes rather than for meeting short-term liquidity needs and therefore do not meet the definition of cash equivalents under the applicable accounting standards.

Rounding off of amounts

The Company is of a kind referred to in ASIC Corporations (Rounding in Financials/Directors' Reports) Instrument 2016/191 and in accordance with that Corporations Instrument amounts in the half-year financial reports are rounded off to the nearest dollar, unless otherwise indicated.

In this regard, such information is provided using similar measures to those used in preparing the statement of profit or loss and other comprehensive income and statement of financial position.

Note 4. Financial Investments

Current assets Term deposits	31 December 2025 $	30 June 2025 $
	5,450,000	-

Term deposits with original maturities exceeding three months are classified as financial investments rather than cash equivalents. These deposits are not held for the purpose of meeting short-term cash commitments and are subject to a higher risk of changes in value due to interest rate fluctuations or withdrawal penalties. Accordingly, they are presented as part of financial assets in the statement of financial position and reported under investing activities in the statement of cash flows.

Mr Ting Yen Chief Technology Officer (tendered 5 September 2025 and resigned on 5 December 2025) Mr Peter Himes Chief Commercial Officer (resigned on 31 October 2025)

During the half-year ended 31 December 2025, a total of 4,500,000 options and 21,500,000 options lapsed following the resignations of Mr Peter Himes and Mr Ting Yen, respectively. As a result of their departure, the vesting conditions attached to these options could no longer be satisfied.

Note 9. Share-based payments

There were no share-based payment arrangements entered into during the half-year ended 31 December 2025.

For the period ended 31 December 2025 a share-based payment reversal of $213,349 (31 December 2024: expense of $248,678) was recognised in the profit or loss statement.

On 5 September 2025, 4,800,000 options were forfeited because the employees did not meet the required service or non-market performance conditions. As a result, the previously recognised expense of $160,170 relating to these options was reversed.

On 4 December 2025, a further 20,000,000 options were forfeited due to employees failing to satisfy the required service or non-market performance conditions. Accordingly, the previously recognised expense of $33,095 associated with these options was reversed.

In addition, 1,500,000 options were forfeited during the period as the relevant employees did not meet the necessary service or non-market performance conditions. Consequently, the previously recognised expense of $35,550 related to these options was reversed.

INDEPENDENT AUDITOR’S REVIEW REPORT

TO THE MEMBERS OF 4DS MEMORY LIMITED

Report on the Half-Year Financial Report

Conclusion

We have reviewed the half-year financial report of 4DS Memory Limited (the company) and controlled entities (consolidated entity) 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, and notes to the financial statements, including material accounting policy information and the directors’ declaration of the consolidated entity comprising the company and the entities it controlled at 31 December 2025, or during the half year.

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 4DS Memory Limited is not in accordance with the Corporations Act 2001 including:

• (a) giving a true and fair view of the consolidated entity’s financial position as at 31 December 2025 and of its performance for the half-year ended on that date; and

• (b) 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.

Independence

We are independent of the company 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 our audit of the annual financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code.

Directors’ Responsibility for the Half-Year Financial 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 the Australian Accounting Standards and the Corporations Act 2001 and for such internal controls as the directors determine is necessary to enable the preparation of the halfyear financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error.

Auditor’s Responsibilities 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 halfyear financial report is not in accordance with the Corporations Act 2001 including: giving a true and fair view of the consolidated entity’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 Corporation 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.
