#### Executive Chair's Letter

#### 31 December 2025
Dear shareholders,

On behalf of the Board of Directors, I am pleased to provide this report on Ioneer's accomplishments in the six-month period from July 1, 2025 to December 31, 2025, the transition period resulting from our decision to change our financial year-end to a calendar year-end.

Our achievements during this reporting period demonstrate Ioneer's continued focus on advancing the strategic partnering process and progressing Rhyolite Ridge towards making a Final Investment Decision (FID).

The strategic partnering process to identify a strong equity partner(s) for Rhyolite Ridge is advancing. We are in active discussions with numerous parties. We currently anticipate concluding the strategic partnering process in the first half of 2026.

Our work has benefited from two significant announcements by the U.S. government in late 2025. The U.S. Department of Interior added boron to the updated Final 2025 List of Critical Minerals and the U.S. Military announced plans to develop domestic small-scale refineries to produce critical minerals using boron. In addition, President Trump issued a proclamation in January 2026 detailing the importance of processed critical minerals and their derivative products to national security, national defense and critical domestic infrastructure.

We are encouraged by the trends we see in government support for critical minerals and believe that as the only permitted, shovel ready lithium-boron project in the U.S., Rhyolite Ridge is uniquely positioned to contribute to onshoring U.S. critical mineral production and create U.S. jobs.

We continue to advance project-related work following the closing of a $996 million loan from the U.S. Department of Energy's Office of Energy Dominance Financing in January 2025.

Our technical resources remained focused on increasing lithium yield and optimizing reagent efficiency to drive improvements to the project economics. After concluding test work to support reducing the total leach duration from 3 days to 2 days earlier in the year, in October 2025, we announced that further test work supported a reduction to 1.5 days, all while consuming the same quantity of acid.

The test work resulted in a material increase in net lithium and boron chemical production due to additional ore being processed. The impact on project economics is substantial. When comparing the 3-day to the 1.5-day leach duration, there is a 64% increase in unlevered NPV to $2.23 billion, and a 350 basis point increase in unlevered IRR to 18.0%, with a modest $15 million increase in initial capital costs. We will be issuing an updated SEC S-K 1300 Technical Report Summary that incorporates the impact of the 1.5-day leach residence improvements in the first half of 2026.

In February 2026, we completed a successful equity placement for gross proceeds of A$72 million (approximately US$50.4 million). Ioneer issued 400 million ordinary shares at an issue price of A$0.18 (~US$0.13) per share. High calibre new and existing shareholders supported the placement, reflecting the world class nature of Rhyolite Ridge.

Thank you for your continued support in our work. It is an honour to work alongside Bernard Rowe and his team. Ioneer is poised to take a transformational step in 2026 to realize the full economic potential of Rhyolite Ridge and we look forward to sharing our continued progress.

#### Six Months in Review

#### 31 December 2025

#### Robust Project Economics
In September 2025, Ioneer announced a material improvement to project economics resulting from reducing vat leach retention time from three (3) days to two (2) days, enabling a reduction in acid consumption per tonne of ore processed and a subsequent increase in ore processed.

In October 2025, we further reduced vat leach retention time to one and a half (1.5) days provided for further reduction in acid consumption and an additional increase in the amount of ore processed. These improvements were achieved with minimal increase in initial capital costs and no change to plant design.

The updated findings further solidify Rhyolite Ridge, on a lithium carbonate equivalent basis, in the lowest cost quartile for lithium production globally, with an estimated all-in sustaining cash cost to produce battery grade lithium hydroxide of US$4,628 per tonne net of expected boric acid revenue in the first 25 years of mine life. The improvements also had a significant positive impact on the Project's unlevered Net Present Value and Internal Rate of Return.

Ioneer engaged the independent services of Independent Mining Consultants, Inc., to compile and complete the updated "South Basin Mineral Resource Estimate" incorporating the reduced retention time in the vat leach from three days to two days to one and a half days. The impact to the Mineral Resources is a 1.7% increase in tonnage above cutoff (due to lower processing cost) with a 3.2% reduction in recovered boric acid and a 1.7% reduction in recovered lithium carbonate (lower recoveries due to shorter leach time).

The current 77-year mine plan is made up entirely of Reserve material (100%), and of that, approximately 35% is Proved Ore Reserve. The resource flexibility allows for a potential extension to the life of the mine or expansion opportunities. Ioneer is in the process of developing our updated technical report as required under Subpart 1300 of the U.S. Securities and Exchange Regulation S-K to incorporate the reduced leach duration to one and a half days. We expect the report expected to be filed in the first half of 2026.

#### Strategic Partnering Process
The strategic partnering process that Ioneer launched in 2025 to identify a strong equity partner is ongoing and the Company is in active discussions with a number of parties. This process benefitted from recent policy developments and government actions supporting domestic critical minerals production.

In November 2025, the U.S. Department of Interior added boron to its Final 2025 List of Critical Minerals. There were also announcements by the U.S. government and President Trump affirming plans to secure domestic production of critical minerals vital to national security and infrastructure. Rhyolite Ridge's status as the only permitted, shovel-ready lithium-boron project in the U.S. positions us well moving forward. Ioneer will continue to explore the impact of these developments as part of the strategic partnering process.

#### Funding
In January 2026, Ioneer announced an institutional placement for gross proceeds of approximately US$50 million (A$72 million) at approximately US$0.13 (A$0.18 per share). This funding supplements the US$996 million loan from the U.S. Department of Energy's Office of Energy Dominance Financing ("DOE Loan") to fund the development of a processing facility at the Project. The placement demonstrated clear market confidence in Ioneer and provided strategic funding to continue to advance Rhyolite Ridge towards a positive Final Investment Decision ("FID").

Conditions precedent to first advance of funds under the DOE Loan includes, among other requirements, closing a strategic partnering agreement for the equity component of the cost of construction, securing additional required funding, and updating the project finance model. We look forward to sharing progress in 2026.

#### EcoPro Lithium Clay Project
In 2023, Ioneer and EcoPro Innovation, a global leader in battery grade high purity lithium hydroxide conversion, signed a Research and Development ("R&D") Memorandum of Understanding ("MOU") to fund and build a commercial-scale refining plant to develop lithium clay.

As of early 2026, the EcoPro Lithium Clay Research & Development project team completed development of the commercially feasible process flow sheet, an important milestone in completion of the MOU. EcoPro Innovation and Ioneer will evaluate the business feasibility and determine the timing for advancing to the next steps in the next six months.

#### Six Months in Review

#### 31 December 2025

#### Engineering
Ioneer has advanced the Lithium Hydroxide Plant to facilitate earlier conversion of the battery grade lithium carbonate into battery grade lithium hydroxide monohydrate, from a planned start in year 4 of operations to year 3. An update of the 2021 scoping study Class IV estimate was completed by Atkins Realis to improve estimation accuracy, including project sustaining capital cost. The production advantages of an onsite lithium hydroxide circuit will result in lower capital cost per tonne of lithium and a substantially lower net operating cost to convert lithium carbonate to lithium hydroxide relative to industry averages.

Also, during the period, Turner and Townsend performed an independent evaluation of the Rhyolite Ridge cost estimate, schedule and risk profile. The independent review team, composed of professionals with specialized expertise in capital cost estimating, project scheduling and risk management, confirmed the quality of the cost estimate and project schedule and risk management framework. It provided an objective view of the Project and the findings further enhanced confidence in Ioneer's planning and execution strategy.

#### Permitting
Ioneer holds all significant Federal and State authorizations required for construction of Rhyolite Ridge. In October 2024, the Center for Biological Diversity filed a federal lawsuit against the U.S. Bureau of Land Management's 24 October 2024 decision to issue a favourable Record of Decision to Ioneer, authorizing the Plan of Operations and completing the National Environmental Policy process.

In November 2024, Ioneer filed a motion to intervene and join the federal government in its defence, which the court allowed in January 2025. Briefing on the merits of the case was completed in December 2025.

The parties have filed the last of their merits briefing and the case is ready for review by the court. The court may choose to hear oral arguments before issuing a decision on the case.

#### Environmental, Health, Safety & Sustainability
Ioneer is committed to sustainability principles and as we grow, seeking to imbed them as fundamental elements in our organisational DNA.

We completed significant enhancements at our greenhouse dedicated to Tiehm's buckwheat to maximize available space for plant growth and seed production as well as improve workflow. These upgrades included construction of a dedicated office and a specialized seed germination area. The Company continues to demonstrate the ability to grow and reproduce Tiehm's buckwheat from seed in a variety of soil types including soils that are low in both lithium and boron.

We look forward to sharing future updates on our new reporting cycle.

#### Highlights for the six months ended 31 December 2025

#### Project Economics
Completed studies to reduce total leach duration from 3 days (DFS) to 2 days (in September 2025) and 1.5 days (in October 2025), respectively. The impact on project economics of transitioning from the 3 days to 1.5 days leach during is a 64% increase in unlevered NPV to $2.23 billion and a 350 basis point increase in unlevered IRR to 18%.

#### Strategic Partnering
We continued to advance the Strategic Partnering process that we currently anticipate concluding in the first half of 2026. U.S. government announcements indicating support for domestic critical minerals supply and processing, including the addition of boron by the U.S. Department of Interior to the updated the Final 2025 List of Critical Minerals demonstrate trends that are positive for Rhyolite Ridge as the only permitted, shovel-ready lithium-boron project in the U.S.

#### Engineering
70% detailed engineering design complete - on target to be construction ready at FID.

#### Sustainability
We upgraded our dedicated greenhouse focused on the germination and propagation of new Tiehm's buckwheat seedlings, continuing to demonstrate the ability to grow and reproduce Tiehm's buckwheat from seed in a variety of soil types including soils that are low in both lithium and boron content.

Business strategy

Our Purpose - we exist to enable a sustainable world for all.

Our Mission - responsibly and profitably provide the materials necessary for realising a sustainable planet.

Our Vision - we see a world in which our global population, our environment and all future generations are thriving.

Our Values - we are imaginative, caring, committed and responsible.

Ioneer's business strategy is focused on developing the 100%-owned Rhyolite Ridge Lithium-Boron Project in Nevada, USA. We believe in an electrified future and the strategic imperative for the USA to develop a domestic battery materials supply chain. We actively promote the development of this battery materials supply chain and look to be a leader in this space.

#### Opportunities
The focus of the Company is developing Rhyolite Ridge. After successfully delivering this Project, Ioneer will pursue other growth initiatives from its existing portfolio (the current estimated resource is open to the north, south and east and does not include the north basin tenements) as well as new opportunities which are value accretive and where balance sheet capacity exists to support future development.

#### Directors' report

#### 31 December 2025

#### Material business risks
The following material business risks have been identified as key issues that have the potential to impact the Company's performance:

&nbsp;&nbsp;&nbsp;&nbsp;● **Health, safety and environmental risks** are of critical importance in ensuring we safely and responsibly build and operate a
 sustainable business.

&nbsp;&nbsp;&nbsp;&nbsp;● **Global economic conditions -** Economic conditions, both domestic and global, may affect the performance of
 the Company and the Project. Adverse changes in macroeconomic conditions, including global and country-specific growth rates, the cost and availability of credit, the rate of inflation, interest rates, exchange rates, government policy
 and regulations, general consumption and consumer spending, input costs, employment rates and industrial disruptions, among others, are variables which while generally outside the control of the Company and its Directors, may result in
 material adverse impacts on the Company's businesses and its operational and financial performance.

&nbsp;&nbsp;&nbsp;&nbsp;● **Execution of the Project -** As the Company progresses the development of its Rhyolite Ridge Project, there
 are risks and uncertainties involved which could result in the Company not delivering on its anticipated timing for future milestones, including those for permitting, taking a Final Investment Decision and for construction. Upon
 construction commencing, the Company and the Project will be subject to risks associated with construction of Stage 1 of the Project until such time as practical completion of construction and first production is achieved.

&nbsp;&nbsp;&nbsp;&nbsp;● **Funding risk** - The Company's continued ability to operate the Project and effectively implement its business
 plan over time will depend in part on its ability to raise funds for operations and growth activities. As announced on 20 January 2025, the Company has closed a US$996 million loan from the U.S. Department of Energy Loan Programs Office
 ("DOE LPO") via the Advanced Technology Vehicles Manufacturing program to support the development of an on-site processing facility at the Project. To the extent that the conditions precedent under the DOE LPO Loan are unable to be
 satisfied or waived, such funding will become unavailable to the Company and would require the Company to find alternative funding sources. There can be no guarantee that the Company will be able to raise sufficient funding on acceptable
 terms, or at all, to fund the Project. Funding terms may also place restrictions on the manner in which the Company conducts its business and impose limitations on the Company's ability to execute on its business plan and growth
 strategies. An inability to obtain finance on acceptable terms, or at all, may cause, among other things, substantial delays in, or prevent, the funding of the Project to Final Investment Decision, and in turn the development or operation
 of the Project.

&nbsp;&nbsp;&nbsp;&nbsp;● **Partner risk -** Construction at the Project will begin following a successful Final Investment Decision
 ("FID"), which is subject to the Company's ability to secure an equity partner to help see the Project into production via the strategic partnership process recommenced in Q2 of 2025 ("Strategic Partnership Process"). There can be no
 assurance that the Strategic Partnering Process will be successful, nor any certainty that the Company will make the FID to commence construction.

&nbsp;&nbsp;&nbsp;&nbsp;● **Offtake risk, including volume and price risks** associated with the
 sale of technical grade lithium carbonate and boric acid, counterparty risk and contract terms. Pricing of lithium is likely to be largely subject to the rate of uptake in electric vehicles. The Company has entered into binding offtake
 agreements and distribution and sales agreements for the supply of boric acid from the Project. There is a risk that the parties to the agreements may not perform their respective obligations or may breach the agreements. The offtake
 agreements include conditions precedent that include the timing of the Final Investment Decision and first production. There can be no guarantee that the Company will be able to renegotiate these conditions precedent on acceptable terms
 should there be delays in the Project.

&nbsp;&nbsp;&nbsp;&nbsp;● **Litigation risk -** The Company and the Project may be involved in litigation and disputes from time to time
 with its contractors, sub-contractors, contractual counterparties and other parties. Litigation and disputes can be costly, including amounts payable in respect of judgments and settlements made against, or agreed to by, the Company or
 Project entities. They can also take up significant time and attention from management and the Board and have an impact on the Company's activities. Accordingly, the Company's involvement in litigation and disputes could have an adverse
 impact on its financial position and performance.

&nbsp;&nbsp;&nbsp;&nbsp;● **Reserves and Resources risk -** No assurance can be given that the estimated Ore Reserve and Mineral
 Resources are accurate or that the indicated level of lithium refined materials, carbonate, boric acid or any other mineral products will be achieved. Such estimates are largely based on interpretations of geological data obtained from
 drill holes and other sampling techniques. Actual mineralisation or geological conditions may be different from those predicted. No assurance can be given that any or all of the Company's Mineral Resources constitute or will be converted
 into Ore Reserve. Actual Ore Reserve and Mineral Resources may differ from those estimated, which could have a positive or negative effect on the Company's financial performance.

#### ioneer Limited

#### Directors' report

#### 31 December 2025
&nbsp;&nbsp;&nbsp;&nbsp;● **Sovereign risk** - relating to the fiscal, tax and regulatory environment in jurisdictions that Ioneer does
 business. The Company's and the Project's operations could be adversely affected by government actions in the U.S. or other countries or jurisdictions in which it has operational exposures or investment or exploration interests. This
 includes increasing regulations and costs associated with climate change and management of carbon emissions, and potential delays as a result of any change in federal administration in the coming U.S. federal elections.

&nbsp;&nbsp;&nbsp;&nbsp;● **Social licence to operate** - Maintaining the Company's social licence to operate by proactively engaging with
 communities, regulators and other key stakeholders.

&nbsp;&nbsp;&nbsp;&nbsp;● **Cyber security** - Ensuring our cyber security through the integrity, availability and confidentiality of data
 within our information and technology systems from either intentional or unintentional disruption ('cyber attack').

&nbsp;&nbsp;&nbsp;&nbsp;● **Climate change** - Managing exposures of physical climate change such as increased frequency of extreme
 weather events including severe weather storms, floods, drought and wildfires which could damage Ioneer's future production infrastructure and operations.

#### ioneer Limited

#### Directors' report

#### 31 December 2025
In October 2024, the Center for Biological Diversity filed a federal lawsuit against the BLM decision. In November 2024, Ioneer filed a motion to intervene and join the federal government in its defence, which the court allowed in January 2025. Briefing on merits of the case was completed in December 2025. The parties have filed the last of their merits briefing and the case is ready for review by the court. The court may choose to hear oral argument before issuing a decision on the case.

We plan to issue a 2026 Sustainability Report in the first half of 2027.

#### Likely developments and expected results of operations
Information on likely developments in the operations of the company and the expected results of operations have not been included in this report because the directors believe it would be likely to result in unreasonable prejudice to the company.

#### Significant changes in the state of affairs
There were no significant changes in the state of affairs of the company during the financial period.

#### Proceedings on behalf of the company
No person has applied to the Court under section 237 of the Corporations Act 2001 for leave to bring proceedings on behalf of the company, or to intervene in any proceedings to which the company is a party for the purpose of taking responsibility on behalf of the company for all or part of those proceedings.

#### Auditor
Ernst & Young continues in office in accordance with section 327 of the Corporations Act 2001.

#### Audit and non-audit services
Details of the amounts paid or payable to the auditor for non-audit services provided during the financial period by the auditor are outlined in note 31 to the financial statements.

The directors are satisfied that no non-audit services were provided during the financial period by the auditor (or by another person or firm on the auditor's behalf), compatible with the general standard of independence for auditors imposed by the Corporations Act 2001.

The directors are of the opinion that the services as disclosed in note 31 to the financial statements do not compromise the external auditor's independence requirements of the Corporations Act 2001 for the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;● all non-audit services have been reviewed and approved to ensure that they do not impact the integrity and objectivity of the auditor; and

&nbsp;&nbsp;&nbsp;&nbsp;● none of the services undermine the general principles relating to auditor independence as set out in APES 110 Code of Ethics for Professional Accountants issued by the Accounting Professional and Ethical
 Standards Board, including reviewing or auditing the auditor's own work, acting in a management or decision-making capacity for the company, acting as advocate for the company or jointly sharing economic risks and rewards.

#### Auditor's independence declaration
A copy of the auditor's independence declaration as required under section 307C of the Corporations Act 2001 is set out immediately after this directors' report.

#### Matters subsequent to the end of the financial period
On 5 February 2026, Ioneer announced the issue of 400,000,000 new fully paid ordinary shares at an issue price of A$0.18 (~US$0.13) per share by way of a single-tranche placement for gross proceeds of A$72 million (~US$50 million). The placement was strongly supported by new and existing shareholders and will be used to accelerate the development of Rhyolite Ridge including long lead items and early works, to advance project readiness, fund environmental permitting expenses and commitments, pay other project costs and fund working capital, meet obligations under the closed DOE Loan and for general corporate purposes.

Other than as mentioned above, in the period since 31 December 2025 and up to the date of this report, there has not been any other item, transaction or event of a material and unusual nature likely in the opinion of directors, to substantially affect the operations of the Group, the results of those operations or the state of affairs of the Group in subsequent financial years.

#### Rounding of amounts
The amounts contained in the Directors' Report have been rounded to the nearest $1,000 (where rounding is applicable) where noted ($'000) under the option available to the Company as provided in ASIC Corporations (Rounding in Financial/Directors' Report) Instrument 2016/191. The Company is an entity to which this legislative instrument applies.

#### Remuneration report

#### 31 December 2025

#### Letter from Committee Chair
Dear fellow shareholders,

On behalf of the Board, I am pleased to present the audited Remuneration Report for Ioneer Ltd ("Ioneer" or the "Company") for the six month period ended 31 December 2025 ("TY2025" or "2025 Transition Period"). This Remuneration Report forms part of the Directors' Report. It has been prepared in accordance with section 300A of the Corporations Act 2001 and has been audited as required by that Act. We will seek shareholders' support for the report at the TY2025 Annual General Meeting.

#### Remuneration Report Context
The Board resolved to change Ioneer's financial year from 1 July – 30 June, to 1 January – 31 December. This has resulted in a six month transition reporting period of 1 July 2025 to 31 December 2025.

#### Changes to the Board and KMP executives
In November 2025, April Hashimoto was appointed as Interim Chief Financial Officer and Olga Smejkalova of Acclime Corporate Services Australia Pty Ltd was appointed as Company Secretary. On 4 December 2025, Ian Bucknell's resigned as an employee and Chief Financial Officer and Company Secretary. No pro-rata incentives were paid and all incentives lapsed. April Hashimoto became an executive Key Management Personnel ("KMP") effective 4 December 2025. There were no other changes KMP during the 2025 Transition Period.

#### Remuneration Report Outcomes

#### Base Salary
KMP annual base salaries were not increased during TY2025. The Board will review KMP remuneration, including base salaries, once the outcome of the strategic partnering process is known.

#### TY2025 Short-term Incentive Plan Performance
The Company's performance in the 2025 Transition Period is reported in the operating and financial review sections of the Financial Report. This performance and how it compared with the specific targets of the Company Scorecard provide the context of the remuneration outcomes outlined in the Remuneration Report.

Short-term Incentive Plan ("STIP") scorecard elements that met or exceeded the Board's expectations were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Realization of previously identified optimization opportunities to reduce total leach duration times from 3 days (in the Definitive Feasibility Study ("DFS)) to 2 days (announced in
 September 2025) to 1.5 days (announced in October 2025) resulting in substantial improvements to the project economics of Rhyolite Ridge, including unlevered NPV improving by 64% to US$2.2 billion and unlevered IRR improving by 24% to
 18%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maintain a high standard of performance with respect to safety, achieving no Occupational Safety and Health Administration ("OSHA") incidents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fiscal discipline resulting in spending levels 6% below the approved budget for TY2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Secured modified air and water permits from the State of Nevada, reached agreement on water rights with Esmeralda County and State of Nevada Regional Water Authority and established a
 standard approach for transfer of future water rights

STIP scorecard elements that were not delivered and consequently did not meet the Board's expectations were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The strategic partner process was delayed and subsequently extended, reflecting significant headwinds that persisted, which resulted in delays to achieving a positive Final Investment
 Decision ("FID") and subsequent commencement of construction of the Rhyolite Ridge project.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advancement of the Tiehm's Buckwheat planting and transplanting plans were delayed as regulatory approvals were delayed by the U.S. Government shutdown in the second half of 2025.

The annual STIP opportunity was halved for the six-month transition period. Executive KMP performance outcomes during TY2025 were mixed.

While the team continued to significantly enhance and optimize Project economics, the prime goal of identifying a strategic partner(s) and moving into advanced negotiations were delayed.

The Board undertook a detailed review of TY2025 STI goals and both team and individual performance. The Board did not exercise discretion in respect to STI outcomes when assessing outcomes compared to established goals and approved an overall performance rating for the team of 70% of target (35% of maximum). When determining individual executive KMP rewards, the Board did make downward adjustments to the individual performance ratings for the Managing Director and Executive Chairman, reflecting delays in the strategic partnering process. Individual executive KMP STIP rewards ranged from 61% to 80% of target (31% to 40% of maximum). STIP awards for TY2025 were delivered in cash, consistent with policy and market practice where the executive KMP are domiciled.

#### ioneer Limited

#### Remuneration report

#### 31 December 2025

#### Long-term Incentive Plan
During the 2025 Transition Period, no Long-term Incentive Plan ("LTIP") Performance Rights ("PRs") were scheduled to vest.

The Board did grant LTIP PRs. In order to transition the performance period for LTIP from the 1 July to 30 June year to a calendar year, the Board adjusted the performance period from 36 months covering 1 July 2025 to 30 June 2028 to 42 months covering 1 July 2025 to 31 December 2028. The number of PRs granted for this longer timeframe were increased proportionally to reflect the longer vesting period.

When establishing LTIP performance targets the Board's goal is to align shareholder value and award outcomes. Half of the targets associated the performance portion of the LTIP scorecard are dependent on project outcomes. Key milestones such as securing full project funding and FID must be achieved for 50% of the PRs granted to vest. Advancing the Project to FID is critical to shareholder value and as a result, executive KMP LTIP awards that vested in FY2025 and FY2024 were reduced by 68% and 66% respectively, reflecting the delays to commencement of construction.

The LTIP plan also includes a time-based element (40% for executive KMP at target, 25% maximum). Time-based LTIP awards are common practice in the U.S., where our Rhyolite Ridge and 73% of our executive KMPs and senior management are located. The Board feels that staff continuity is critical to advancing the Rhyolite Ridge project. To ensure this, Company must attract and retain employees by providing a compensation structure that reflects the markets in which its employees live and work, which includes time-based LTIP. Despite the headwinds facing the lithium sector in the last three years, the Company has experienced low turnover at the executive KMP and senior levels of management, with an annual retention rate well above 90%.

#### Board fees
No changes were made to board fees. Board fees remain unchanged since 2020.

#### Response to first strike
At the October 2025 Annual General Meeting, 72.7% of shareholders voted for the FY2025 remuneration report, 2.3% below the 75% which constituted a first strike.

Feedback from shareholders indicates that some were dissatisfied with the remuneration framework, and/or others followed proxy adviser recommendations not to support the FY2025 remuneration report. Steps taken over the transition reporting period to address concerns include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• STIP scorecard assessment, and consequently payment outcomes were materially lower, below target, and reflective of mixed outcomes and shareholder experience

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board decided to discontinue, with immediate effect, the Company's practice of giving employees, including executive KMPs, the option to receive a 20% uplift in payment of STI by both
 deferring the payment for one year and converting the cash payment to equity. While the policy change is not as effective at conserving cash, or encouraging ownership, the Board assessed the risk as minimal, and addressed the concerns
 raised by proxy advisers in this instance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• No one-off equity grants were made.

We also note that proxy adviser Institutional Shareholder Services ("ISS"), whose recommendations appeared to be followed by minority of shareholders that voted against the remuneration report, incorrectly attributed 40% of the LTIP as subject to service-only vesting. At maximum, only 25% of the LTIP is subject to service, which is less than practice in the market in which most executive KMP are domiciled. ISS Australia policy does not support the use of time-based equity as it is inconsistent with 'better market practice' and shareholder interests. The guidelines do not say why paying executives in long term equity rather than cash salary is poorer practice and against shareholder interests. ISS also compared our US executive pay levels and composition to the lower Australian pay levels and composition. ISS did not indicate why Ioneer should risk turnover by varying from dominant market practice in which our executives are domiciled.

In addition to responses to FY2025 remuneration report vote feedback, we will continue to engage with shareholders and proxy advisers for additional feedback and insights. Subject to that further engagement, we believe executive KMP remuneration is conservatively configured to meet most market standards while conserving cash, and appropriate for a resources company in the development stage. That is, it provides for a low proportion of remuneration to be received as cash, a higher proportion as equity, and is mostly contingent on performance.

I trust that you find the remuneration report is informative and that it addresses any queries you have. Any further questions are welcomed and will be encouraged at the upcoming Annual General Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Remuneration governance** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.1** **Nomination & Remuneration Committee** 

Remuneration governance is overseen by the Nomination & Remuneration Committee. The Committee is a committee of the Board established in accordance with the Company's constitution and authorised by the Board to assist it in fulfilling its statutory, fiduciary, and regulatory responsibilities.

The ASX Corporate Governance Council's "Corporate Governance Principles and Recommendations" (ASX Recommendations) recommend that the Company has formal and rigorous processes for the appointment and reappointment of directors to the Board. The Committee was established to assist the Board by undertaking the roles and exercising the responsibilities set out in the Nomination & Remuneration Committee Charter. A copy of this Charter is available on the Company's website.

The Committee aims to bring transparency, focus and independent judgment to these roles. The Committee will review and make recommendations to the Board on matters relevant to these roles and responsibilities, and as required to satisfy the Corporations Act, ASX Recommendations and ASX Listing Rule requirements relevant to these roles and responsibilities. The Committee currently comprises the following independent non-executive directors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Alan Davies (chair);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Rose McKinney-James; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Timothy Woodall

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2** **Remuneration advisors** 

The Nomination and Remuneration Committee engages external advisors as required. External advisors provide advice on market remuneration levels and mix, market trends, incentives and performance measurement, governance, taxation and legal compliance.

None of the Committee's engagements with remuneration advisors were for work that constituted a remuneration recommendation for the purposes of the Australian *Corporations Act 2001*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3** **Share trading policy** 

The Ioneer Securities Trading Policy applies to all NEDs, executives and employees. The policy prohibits employees from dealing in Ioneer securities while in possession of material non-public information relevant to the Company.

Executives must not enter into any hedging arrangements over unvested equity under the Company's equity plan. The Company would consider a breach of this policy as gross misconduct, which may lead to disciplinary action and potentially to dismissal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.4** **Reasons for remuneration "strike"** 

The following table summarises the issues identified by shareholders and proxy advisers, and the Company's response.

|:---|:---|
| Feedback | Response |
| FY 2025 maximum<br> total remuneration<br> quantum too high | Ioneer compares executive pay levels to the pay levels of executives in the same geographic markets (primarily the U.S. and Canada, with consideration for Australia) and industry (resources). The policy is to pay between the 25<sup>th</sup> percentile and median rates of pay for individuals with the qualifications and experience to do the role. Actual pay rates approximate policy positioning. Therefore the maximum remuneration quanta is not high, not low; it is just right.<br>ISS Australia compared our primarily North American executive pay levels and composition for the CEO to the Australian pay levels and composition. Australian pay levels are lower than US pay levels. Yet this is irrelevant. Much as the board would like to pay less, the fact is that our assets are US based, and managed by majority US based executives. To acquire, and retain, US based executives we have to pay North American rates of pay. To do otherwise would risk material harm to our business, and consequently shareholder value.<br>Executive KMP annual base salaries were not increased during TY2025. While the annual LTIP grants are greater as a percentage of salary, they reflect the longer performance and service periods of 42 months (compared with 36 months) in recognition of the transition of the financial year to a calendar year. The annual percentage of maximum STIP and LTIP opportunity remains unchanged. |
| FY2025 Managing<br> Director's STIP<br> outcome was high<br> whereas the total<br> shareholder return<br> during the period<br> declined. | TY2025 STIP scorecard assessment, and consequently payment outcomes were materially lower, below target, and reflective of the shareholder experience.<br>This included the Board making downwards adjustments to the individual performance ratings for the Managing Director and Executive Chairman, reflecting delays in the strategic partnering process. |
| STIP 20% uplift if<br> electing to receive as<br> deferred equity | The Board decided to discontinue, with immediate effect, the Company's practice of giving employees, including executive KMPs, the option to receive a 20% uplift in payment of STI by both deferring the payment for one year and converting the cash payment to equity. While the policy change is not as effective at conserving cash, or encouraging ownership, the board assessed risk as minimal, and a unique practice both in Australia and the US, so have addressed the concern of proxy advisers in this instance. |

| Feedback | Response |
| That 40% of the LTI is<br> service-based | ISS incorrectly attributed 40% of the LTIP as subject to service-only vesting. At maximum, only 25% of the LTIP is subject to service. This is less than practice in the market in which most executive KMP are domiciled. ISS Australia policy does not support the use of time-based equity as it is inconsistent with 'better market practice' and shareholder interests. The guidelines do not say why paying executives in long term equity rather than cash salary is a poor practice and against shareholder interests.<br>Our purpose is to provide equity in lieu of cash salary for shareholder alignment, cash conservation, consistency with non-KMP employee remuneration, and consistency with U.S market practice as the majority (approximately 83%) of the Company's employees are located. |
| Relative TSR hurdle<br> has vesting starting at<br> the 25<sup>th</sup> percentile and<br> lacks a positive TSR<br> gateway. | A positive TSR gateway can lead to binary results. It can be demotivating if relative performance outperforms peers during a challenging market environment.<br>Our approach to avoid binary outcomes and the drawbacks of a positive TSR gateway has been a modifier. If the share price is 33% lower or higher over the performance period, the award result will be reduced or increased by 20%. This is consistent with maintaining a vesting schedule that varies vesting with a greater range of relative TSR performance. This permits realised remuneration to reduce for performance that is poorer than peers, and increase for performance greater than peers. |
| LTI milestone<br> granularity lacking | The Board has continued to set LTI targets that assume an FID will be taken and the Project advances into construction and production. While the Board recognises the desire for milestone granularity, this is not currently practical nor material. The Board has not set specific targets for budgets and schedule because these will not be known until the FID decision is made. The FID decision, on which vesting is contingent, is material. |
| One-off grant under<br> transition incentive<br> plan | No one-off equity awards were made in TY2025 |

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Executive Remuneration** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **Remuneration strategy** 

The principles of the Ioneer remuneration policy are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attract, retain and motivate directors, executives and employees who will create value for shareholders by providing remuneration packages that are aligned with shareholder interests, are
 equitable and externally competitive;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide a remuneration balance weighted toward risk and return to align with shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• clearly align short and long-term company objectives to financial awards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• be fair and appropriate having regard to the performance of the Company and the relevant director, executive or employee and the interests of shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• conserve cash in the development phase of the business by granting equity in lieu of cash where appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comply with relevant legal requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **Relationship with company performance** 

The Ioneer executive compensation framework provides for fair, competitive remuneration that aligns potential rewards with the Company's objectives while being transparent to shareholders. We are a Company with a single, pre-development project, with 83% of our team, who are administered under this compensation program located in the U.S. and one employee, the Managing Director, located in Australia. Consequently, our compensation framework aligns with U.S. standards. Typically, this means proportionately less cash and higher equity than the Australian market standard, with some of the equity contingent on service to make up for the relatively low cash proportion. Performance objectives for STI and equity vesting are set such that achievement would accelerate development during our current pre-production phase for higher shareholder value. This means that the value of remuneration realised at vesting is highly aligned with the value realised by investors.

Key remuneration elements are reviewed annually to determine appropriate awards based upon factors such as individual performance, Company results and competitive benchmark survey data. The following is a brief description of the approach for each element:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Base salary** is reviewed annually and adjusted for individual performance and benchmarks that may be reviewed from time to time to ensure
 competitiveness. Executive KMP annual base salaries were not increased during TY2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Short term incentives** are reviewed annually with awards granted based upon individual performance and Company results. STI targets are benchmarked
 from time to time to ensure competitiveness. STIs may range from 0% to 200% of target. The Board reserves the right to grant STI outcomes greater than 200% of target for exceptional contributions to Company objectives, as well as
 exercise negative discretion when formulaic outcomes do not align with the shareholder experience. In February 2026, the Board decided to discontinue, with immediate effect, the Company's practice of giving employees, including KMPs, the
 option to receive a 20% uplift in payment of STI by both deferring the payment for one year and converting the cash payment to equity. While the purpose of the practice was to encourage employee retention, increase alignment and conserve
 cash, it was a unique practice in the U.S. and Australia, and therefore was discontinued .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Equity grants** are reviewed annually. The Board has a practice of granting a target grant ratio with a ratio of 60% performance-based PRs and 40%
 time-based PRs. At maximum, the ratio is 75% performance-based and 25% time-based PRs. A key risk for Ioneer is not being able to attract and retain qualified and experienced U.S. executives and senior management. The remuneration
 framework is based on optimal shareholder alignment, cash conservation and alignment with U.S. market standards as the jurisdiction in which the majority of our employees are located.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Performance-based PRs comprise 60% of the annual target grant value (75% at maximum). The final vesting may range between 0% to 200% of grant based on achievement of a scorecard of business
 objectives suited to the Company's current pre-production phase, such that if all were achieved, they would add substantially to shareholder value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Time-based PRs make up 40% of the annual target grant value, equivalent to 25% of maximum potential grant value. Vesting is contingent upon the employee remaining employed to the vesting
 date. Time-based PRs are a standard component of compensation in the U.S. market to encourage retention in key positions, which aligns with our ability to deliver results to shareholders; conserves cash that would otherwise have to be
 used for higher cash salaries and meets U.S. market standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3** **Remuneration framework – linking reward to performance** 

Remuneration information is derived from relevant remuneration surveys conducted by independent third parties. Remuneration is benchmarked against a peer group of direct competitors and a sector peer group.

Ioneer's remuneration framework and executive reward strategy provides a mix of fixed and variable remuneration with a blend of short-term incentives and long-term equity grants. The key elements of the remuneration packages are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Annual base salary:** reviewed annually and adjusted based upon individual performance and competitive benchmarks that may be reviewed from time to
 time to ensure competitiveness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Post-employment benefits:** superannuation contributions for Australian based executives and similar retirement benefits savings for non-Australia based
 executives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Total Fixed Remuneration (TFR):** Annual base salary plus superannuation for Australia based executives and annual base salary for non-Australia based
 executives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Short-term incentive (STI):** Remuneration for performance measured over one year or less, including any deferred amounts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Equity incentive grants:** Performance and/or time-based equity granted under shareholder approved equity plans.

At maximum, the remuneration mix is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3.1** **Base Salary** 

Executive KMP are paid base salary in cash which is competitive in the sector and markets in which the Company operates and is consistent with the responsibilities, accountabilities and complexities of the respective roles. The Company benchmarks executive KMP base salaries against resource industry market surveys for lithium companies which are published annually. Additionally, the pay levels of executive KMP positions in the Company may be benchmarked against national market executive remuneration surveys. It is the Company's policy to position itself at the P25-P50 level of the market when benchmarking TFR. Base salary is reviewed annually and adjusted based upon individual performance and competitive benchmarks that may be reviewed from time to time to ensure competitiveness.

Executive KMP annual base salaries were not increased during TY2025. The Board will review executive KMP base salaries once the outcome of the strategic partnering process is known. The base salaries for TY2025 were prorated for the six-month performance period based on the annual amounts that were approved by the Board on the recommendation of the Nomination and Remuneration Committee which are as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| | | **31-Dec-25** | **31-Dec-25** | **30-Jun-25** | **30-Jun-25** |
| **Base salary <sup>1</sup>**<br>| **% Increase**<br>| **A$** | **US$** | **A$** | **US$** |
| James D Calaway | 0% |  | 250000 | - | 250000 |
| Bernard Rowe | 0% | 585000 | - | 585000 | - |
| Ian Bucknell <sup>2</sup> | 0% | 433000 | - | 433000 | - |
| April Hashimoto <sup>3</sup> |  | - | 12710 | - | - |
| Ken Coon | 0% | - | 268000 | - | 268000 |
| Yoshio Nagai | 0% | - | 284000 | - | 284000 |
| Chad Yeftich | 0% |  | 292000 | - | 292000 |
| Matt Weaver | 0% | - | 333000 | - | 333000 |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Base salaries are shown in the above table at contract amounts. Where executive KMP have not worked a full-time load or superannuation caps have been met and excess amounts taken as salary,
 it will not agree with the table in the "Statutory Remuneration" section below. April Hashimoto was appointed Interim Chief Financial Officer on 6 November 2025 pursuant to a consulting services contract whereby she is compensated based
 on an hourly rate. April Hashimoto invoiced the Company for US$12,710 for services she provided during the period in TY2025 that she was an executive KMP (4 December 2025 to 31 December 2025).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Ian Bucknell resigned as Chief Financial Officer and Company Secretary effective 4 December 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) April Hashimoto was appointed Interim Chief Financial Officer on 6 November 2025 pursuant to a consulting contract by which she is paid based on an hourly rate. The amount shown as base pay
 reflects the amount invoiced under the consulting contract for the period that April Hashimoto was an executive KMP (4 December 2025 to 31 December 2025).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3.2** **Short-Term Incentive (STI)** 

Executive KMP can earn an annual STI based on a percentage of their base salary. The STI percentage increases with seniority to ensure a higher proportion of remuneration is "at risk" for more materially accountable employees.

The features and approach for the Ioneer STI plan are as follows.

---

| | |
|:---|:---|
| Feature | Approach |
| Purpose | Align team and individual performance and behaviours with annual Group objectives.<br>Provide individuals with a competitive market position for total reward (i.e. variable and fixed pay components).<br>|
| Eligibility | Those considered for participation in the program must be able to impact the performance of their own work area, their business or function and contribute to the Group's overall performance. |
| Form of payment | TY2025 STIP was awarded in cash, which is the default form of payment. The Company reserves the right to award STIP as equity if appropriate.<br>In February 2026, the Board decided to discontinue, with immediate effect, the Company's practice of giving employees, including executive KMPs, the option to receive a 20% uplift in payment of STI by both deferring the payment for one year and converting the cash payment to equity.<br>|
| Opportunity | &nbsp;&nbsp;&nbsp;&nbsp; The maximum STI opportunity as a percentage of base salary for the executive KMP with the numbers in brackets reflecting the shorter performance period for TY2025 are as follows:<br>Executive Chair: 120% (60% for TY2025)<br> Managing Director: 160% (80% for TY2025)<br> Senior Vice President Engineering & Operations: 100% (50% for TY2025)<br> Interim Chief Financial Officer: 100% (50% for TY2025)<br> Vice President Human Resources: 80% (40% for TY2025)<br> Vice President Commercial Sales & Marketing: 80% (40% for TY2025)<br> Vice President – Corporate Development and External Affairs: 80% (40% for TY2025)<br>The maximum STI was prorated for the TY2025 six-month performance period (1 July 2025 to 31 December 2025).<br>Target STI opportunity is half of the maximum STI opportunity.<br>|
| Performance period | Six months from 1 July 2025 to 31 December 2025 and thereafter 1 year, 1 January to 31 December |
| Performance<br> measures<br>| Annual executive KMP performance is set and assessed based upon a set of key Company targets (scorecard) that directly affect shareholder value and are directly linked to the Ioneer Strategic Plan. This formulaic scorecard outcome is 75% of the executive KMP's individual STI award.<br>Each scorecard goal is measured, weighted according to its importance, and assessed quantitatively.<br>The remaining 25% is the contribution to organisational objectives and performance in role (individual component).<br>Both the scorecard and individual component can achieve up to 200% of target (100% of maximum).<br>At the start of each performance period, the Board determines Company hurdles with threshold and maximum performance levels which form the STI goal. Additionally, the MD reviews and approves the goals of each executive KMP, ensuring alignment with Company objectives.<br>The target levels of performance set by the Board are challenging and are driven by an annual target setting exercise and longer-term strategic objectives. Achievement of target levels of performance delivers the payment of 50% of STI maximum opportunity.<br>|

|:---|:---|
| **Feature** | **Approach** |
| Board discretion | The Board reserves the right to grant above 200% of target STI for truly exceptional contributions to the business or to exercise negative discretion if the formulaic outcome does not accord with the shareholder experience, behaviours not consistent with the Company's code of conduct, reputational damage, safety or environmental expectations, or the Board's overall assessment of performance on a holistic basis. |
| Clawback | The Board can clawback previous incentive awards that may have been awarded erroneously. The following are examples of such circumstances, including:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A restatement of any financial measure or target upon which an incentive award was based;<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A restatement of the Company's financial statements even though the restatement did not involve a metric that was explicitly part of an incentive award calculation;<br> • The serious or gross misconduct, fraud, bribery, severe reputational damage, and any other deliberate, reckless, or unlawful conduct that may have a serious adverse impact on Ioneer, its reputation, customers, the environment, or its people which resulted in dismissal, or the Board considers at its discretion would have justified the dismissal. In exceptional cases, Remco may determine that recovery of incentive awards is appropriate though dismissal does not occur. |
| Treatment on<br> termination<br>| If the executive is deemed a good leaver, STI is rewarded on a pro rata basis for time served. PRs lapse if an employee resigns. |

Details of the STI scorecard for the 2025 Transition Period are disclosed in the table below. The STI scorecard is reflective of Ioneer's current stage of development in obtaining approval for environmental permits, obtaining the necessary funding and preparing the Company to take a Final Investment Decision and begin construction on the Project.

The STI scorecard for TY2025 was as follows:

![graphic](image00096.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3.3** **Long-Term Incentive (LTI) Equity Grants** 

The executive KMP LTI equity grant is comprised of 2 parts, a performance-based PR grant and a time-based PR grant. During TY2025, executive KMPs were granted LTI for the performance period 1 July 2025 to 31 December 2028 (the "TY2025 LTI Grant"). In order to transition the performance period for LTIP from the 1 July to 30 June year to a calendar year, the Board adjusted the performance period for TY2025 LTI Grant from 36 months covering 1 July 2025 to 30 June 2028 to 42 months covering 1 July 2025 to 31 December 2028. The number of PRs granted for this longer timeframe were increased proportionally to reflect the longer vesting period.

The tables below present the features and approaches for each of the performance-based and time-based components of the TY2025 LTI Grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.3.3.1** **Performance-based LTI PRs (performance period 1 July 2025 to 31 December 2028)** 

The following table presents the terms and conditions of the performance-based component of the TY2025 LTI Grant:

---

| | |
|:---|:---|
| **Feature** | |
| Purpose | To align executive accountability and remuneration with the long-term interests of shareholders by rewarding for the delivery of sustained performance. |
| Participants | All executive KMP and senior management members.<br>The Board may at its discretion make invitations to or grant awards to eligible persons. Eligible persons include executive directors or executive officers of the Group, employees, contractors or consultants of the group or any other person. |

| Instruments issued | Performance rights (PRs) to acquire ordinary shares in the Company for nil consideration.<br>Within 30 days after the vesting date in respect of a vested instrument, the Company, at its discretion only, must either allocate shares or procure payment to the participant of a cash amount equal to the market price of the shares which would have otherwise been allocated. |
| Allocation value | 10-day VWAP prior to start of the performance period |
| Maximum value | &nbsp;&nbsp;&nbsp;&nbsp; Maximum incentive opportunity as a percentage of base salary is unchanged from FY2025. The numbers in brackets reflect the longer performance period (42 months compared with 36 months) for TY2025: Amounts are as follows:<br>Executive Chair: 72% (84% for TY2025)<br> Managing Director: 144% (168% for TY2025)<br> Vice President Human Resources: 48% (56% for TY2025)<br> Vice President Commercial Sales & Marketing: 48% (56% for TY2025)<br> Senior Vice President Engineering & Operations: 102% (119% for TY2025)<br> Vice President Corporate Development and External Affairs: 60% (70% for TY2025)<br>Executive KMP are granted 50% of the maximum number of PRs to vest. |
| Performance period | 3.5 years, 1 July 2025 to 31 December 2028 (to transition to a calendar year performance period), thereafter 3 years |
| Vesting Date | As soon as practicable after end of performance period but not later than March 2029 |
| Performance<br> measures | Annually executive KMP performance targets are set and then assessed on a range of key measures that are critical to shareholder value and are directly linked to the Ioneer Strategic Plan. At this point in the Rhyolite Ridge Project, targets are focused on moving through the Project's objectives of permitting, engineering, funding and construction.<br>Each scorecard measure is measured, weighted according to its importance, and is assessed objectively.<br>At the grant date, the Board determines the hurdles and minimum, target and maximum levels of performance which form the LTI scorecard.<br>The target levels of performance set by the Board are challenging and are driven by an annual goal setting exercise and the longer-term strategic plan. Achievement of target levels of performance delivers the payment of 50% of LTI maximum opportunity. Payments from threshold to maximum opportunity are on a straight-line basis consistent with the level of performance attained.<br>Details can be found in section 4.3.3.2 below. |

| Acquisition of<br> performance rights | The PRs are issued by the company and held by the participant subject to the satisfaction of the vesting conditions. The number of PRs held may be adjusted pro-rata, consistent with ASX adjustment factors for any capital restructure.<br>If the PRs vest, executives receive newly issued shares or shares acquired on market. Trading restrictions may apply to the newly issued shares. |
| Treatment of<br> dividends and voting<br> rights | Unvested PRs do not have voting rights or accrue dividend benefits. |
| Restriction on<br> hedging | Hedging of PRs by executives is not permitted |
| Treatment on<br> termination | If the executive is deemed a good leaver, PRs are prorated for time served. PRs lapse if an employee resigns. |
| Board Discretion | The board may apply downward discretion as appropriate.<br>The Company may adjust downwards the number of performance-based PRs where there has been a material negative misstatement of results to align executive awards with shareholder outcomes. |
| Clawback | The Board can clawback previous incentive awards that may have been awarded erroneously. The following are examples of such circumstances, including: <br>&nbsp;&nbsp;&nbsp;&nbsp;• A restatement of any financial measure or target that an incentive award was based upon; <br> &nbsp;&nbsp;&nbsp;&nbsp;• A restatement of the Company's financial statements even though the restatement did not involve a metric that was explicitly part of an incentive award calculation; <br> &nbsp;&nbsp;&nbsp;&nbsp;• The serious or gross misconduct, fraud, bribery, severe reputational damage, and any other deliberate, reckless, or unlawful conduct that may have a serious adverse impact on Ioneer, its reputation, customers, the environment, or its people which resulted in dismissal, or the Board considers at its discretion would have justified the dismissal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.2** **TY2025 performance and STI outcome (performance period 1 July 2025 to 31 December 2025)** 

STI targets for TY2025 were primarily focused upon advancing Project funding through the strategic partnering process, enhancing Project economics through plant optimization, conserving cash by exercising fiscal discipline and additional sustainability measures. At the end of the performance period, the Board undertook a thorough assessment of performance outcomes relative to established targets.

The following table details the STIP goals for the TY2025 performance period and the assessed outcomes:

------

![graphic](image00098.jpg)

Company performance relative to STIP goals in TY2025 was mixed. The team exceeded established goals for Rhyolite Ridge plant optimization, exercised fiscal discipline to spend ~6% below budget, achieved excellent safety outcomes, obtained State of Nevada permit modification approvals while making excellent progress in transferring operational water rights and maintained team continuity at the senior levels. Unfortunately, the team was not able to make substantial progress in advancing the strategic partnering process and efforts to gain Federal Agency approvals to outplant Tiehm's Buckwheat were negatively impacted by the U.S. Government extended shutdown.

The STI calculation is comprised of a 75% component for Company performance and a 25% component for individual performance and contribution to organisational objectives. The Board approved a rating for the Company performance component of TY2025 STI of 70% of target (35% of maximum).

The following table provides the calculated outcome for each measure in the TY2025 STI scorecard.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Each executive KMP annual target STI shown in the table was prorated for the six-month performance period (1 July 2025 to 31 December 2025). The STI awards for executive KMP were split
 between Company performance (75%) and individual performance (25%) and awarded in cash.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The Board made downward adjustments to the individual performance ratings for the Managing Director and Executive Chairman, reflecting delays in the strategic partnering process.

&nbsp;&nbsp;&nbsp;&nbsp;(3) April Hashimoto provides services pursuant to a consulting agreement and therefore her STI payout was based on the services invoiced from her designation as an executive KMP on 4 December
 2025 to 31 December 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(4) For Ken Coon and Yoshio Nagai, the STI annual targets were reduced from 40% to 20% to reflect their 50% work schedule.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.3** **LTI PRs vesting** 

No LTI PRs were scheduled to have the performance or service period end in TY2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.4** **Statutory remuneration** 

The following table sets out KMP remuneration for the 2025 Transition Period and the 2025 Financial Year in US Dollars and has been prepared in accordance with the requirements of Section 300A of the Australian Corporations Act 2001 and associated accounting standards.

**Note 1. Basis of preparation and Material accounting policies**

&nbsp;&nbsp;&nbsp;&nbsp;**1.1** **Corporate information** 

The consolidated financial statements of Ioneer Ltd (the Company or parent) and its subsidiaries (collectively the Group) for six months ended 31 December 2025 was authorised for issue in accordance with a resolution of the Directors on 18 March 2026.

The Group is a for-profit company limited by shares and incorporated in Australia whose shares are publicly traded on the Australian Securities Exchange under the ticker code "INR" and on Nasdaq under the ticker code "IONR". The registered office of the Company is suite 16.01, 213 Miller Street, North Sydney, NSW 2060 Australia.

The Group is principally engaged in the development of the Rhyolite Ridge lithium-boron deposit in the state of Nevada, United States of America. Further information about the nature of the Group's operations and activities is provided in the Directors' Report. Information on the group structure is set out in Note 29 of this report and information on other related party disclosures of the Group is provided in Note 32.

&nbsp;&nbsp;&nbsp;&nbsp;**1.2** **Basis of preparation** 

These consolidated financial statements of the Group have been prepared in accordance with Australian Accounting Standards and Interpretations issued by the Australian Accounting Standards Board ('AASB') and the Corporations Act 2001, as appropriate for for-profit oriented entities. These financial statements also comply with International Financial Reporting Standards as issued by the International Accounting Standards Board ('IASB'), including new or amended accounting standards effective for reporting periods beginning 1 July 2025.

The consolidated financial statements have been prepared on a historical cost basis. The consolidated financial statements are presented in USD, and all values are rounded to the nearest thousand ('$000), except where otherwise indicated. The Group has prepared the financial statements on the basis that it will continue to operate as a going concern.

The consolidated financial statements provide comparative information in respect of the previous period.

&nbsp;&nbsp;&nbsp;&nbsp;**1.3** **Change in fiscal year** 

On September 25, 2025, the Board of Directors approved a change in the Company's financial year end from 30 June to 31 December to better align the accounting reporting period with its subsidiaries in the United States of America, where the bulk of the group's business operations are located. This financial report is presented for the 6-month transition period from 1 July 2025 to 31 December 2025 with the comparative reporting period being the 12 months ended 30 June 2025. Hence, the amounts presented in the financial statements are not entirely comparable.

&nbsp;&nbsp;&nbsp;&nbsp;**1.4** **New or amended Accounting Standards and Interpretations** 

The Group has adopted all of the new or amended Accounting Standards and Interpretations issued by the Australian Accounting Standards Board ('AASB') that are mandatory for the current reporting period.

Any new or amended 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 Group.

The following standards and interpretations that have recently been issued but are not yet mandatory, have not been early adopted by the Group for the six months ended 31 December 2025. The Group's management have yet to assess the impact of these new or amended Accounting Standards and Interpretations, which are most relevant to the Group are set out below:

***AASB 18 - Presentation and Disclosure in Financial Statements***

AASB 18 replaces AASB 101 as the standard describing the primary financial statements and sets out the requirements for the presentation and disclosure of information in AASB-compliant financial statements. Amongst other changes, it introduces the concept of 'management-defined performance measure' to financial statements and requires the classification of transactions presented within the statement of profit or loss within one of five categories - operating, investing, financing, income taxes and discontinued operations. It also provides enhanced requirements for the aggregation and disaggregation of information.

Note 1. Basis of preparation and Material accounting policies (continued)

***AASB 7 and AASB 9 - Financial Instruments***

The amendments to AASB 7 and AASB 9 clarify that a financial liability is derecognised on settlement date, i.e. when the related obligation is discharged, cancelled, expires or the liability otherwise disqualifies for recognition. It also clarifies how to assess contractual cash flow characteristics.

The Group is currently assessing the impact the amendments will have on current practice.

&nbsp;&nbsp;&nbsp;&nbsp;**1.5** **Basis of consolidation** 

**Controlled entities**

The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as at 30 June 2025. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if, and only if, the Group has:

● Power over the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee)

● Exposure, or rights, to variable returns from its involvement with the investee

● The ability to use its power over the investee to affect its returns

Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

● The contractual arrangement(s) with the other vote holders of the investee

● Rights arising from other contractual arrangements

● The Group's voting rights and potential voting rights

There has been no change in the control of any subsidiaries during the financial period. All subsidiaries are 100% owned by the Company (30 June 2025: 100%).

**Transactions eliminated on consolidation**

All intercompany balances and transactions, including unrealised profits arising from intra-group transactions, have been eliminated in full.

**Accounting policies**

The financial statements of subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies.

&nbsp;&nbsp;&nbsp;&nbsp;**1.6** **Current versus non-current classification** 

The Group presents assets and liabilities in the statement of financial position based on current and non-current classification.

An asset is classified as current when: it is either expected to be realised or intended to be sold or consumed in the Group's normal operating cycle; it is held primarily for the purpose of trading; it is expected to be realised within 12 months after the reporting period; or the asset is cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least 12 months after the reporting period. All other assets are classified as non-current.

A liability is classified as current when: it is either expected to be settled in the Group's normal operating cycle; it is held primarily for the purpose of trading; it is due to be settled within 12 months after the reporting period; or there is no right to defer the settlement of the liability for at least 12 months after the reporting period. All other liabilities are classified as non-current.

Deferred tax assets and liabilities are always classified as non-current assets and liabilities.

Note 1. Basis of preparation and Material accounting policies (continued)

&nbsp;&nbsp;&nbsp;&nbsp;**1.7** **Critical accounting estimates and judgements** 

The preparation of these financial statements in conformity with Australian Accounting Standards has required management to make judgements, estimates and assumptions which impact the application of policies and reported amounts of assets and liabilities, income and expenses. These estimates and associated assumptions are based on historical knowledge and various other factors that are believed to be reasonable in the circumstance. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed regularly and revisions to accounting estimates are reviewed in the period in which the estimate is revised. The most significant estimates and assumptions are based on historical knowledge and various other factors that are believed to be reasonable in the circumstance. Actual results may differ from these estimates.

**Exploration and evaluation assets**

The Group's policy for exploration and evaluation expenditure is set out in Note 12. The application of this policy requires certain judgements and assumptions as to the future events and circumstances, in particular the assessment of whether economic quantities of reserves will be found. Any such judgements and assumptions may change as new information becomes available. If, after capitalisation of expenditure under the policy, there are indicators that the capitalised expenditure will not be recovered by future exploitation or sale, then an impairment test is performed and the relevant amount will be written off in the statement of profit and loss. Changes in judgements and assumptions may result in a material adjustment to the carrying amount of exploration and evaluation assets.

**Share-based payment transactions**

The Group measure the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the date on which they are granted.

&nbsp;&nbsp;&nbsp;&nbsp;**1.8** **Foreign Currency Transactions and Balances** 

**Functional and presentation currency**

The functional currency of each of the Group's entities is measured using the currency of the primary economic environment in which that entity operates.

The functional currency of the entities in the Group is predominately US Dollars, with the exception of Ioneer Ltd which has a functional currency of Australian Dollars.

**Transactions and balances**

Foreign currency transactions are translated at the foreign exchange rate at the date of transaction. Monetary assets and liabilities denominated in a foreign currency at the end of the reporting period are translated at the year-end exchange rate. Exchange differences arising on the translation of monetary items are recognised in the statement of profit and loss.

Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of transaction. Exchange differences arising on the translation of non-monetary items are recognised directly in other comprehensive income to the extent that the underlying gain or loss is recognised in other comprehensive income; otherwise, the exchange difference is recognised in the profit and loss.

**Presentation of foreign exchange gains or losses in the statement of profit or loss**

The Group presents its foreign exchange gains and losses within net financing income/(costs) in the statement of profit and loss.

**Borrowings**

Loans and borrowings are initially recognised at the fair value of the consideration received, net of transaction costs. They are subsequently measured at amortised cost using the effective interest method. The transaction costs that are incurred in advance of the loan and borrowings are deferred and recognised as other receivables. These costs will be subsequently accounted for as part of the amortised cost of the borrowings.

Note 1. Basis of preparation and Material accounting policies (continued)

**Finance costs**

Finance costs attributable to qualifying assets are capitalised as part of the asset. All other finance costs are expensed in the period in which they are incurred.

&nbsp;&nbsp;&nbsp;&nbsp;**1.9** **Going Concern** 

The Directors believe that the going concern basis is appropriate for the preparation of the consolidated financial statements, notwithstanding continued losses and no ongoing revenue stream, with the Group having a strong fund-raising track record.

After completing a financing in February 2026 raising gross proceeds of A$72 million (~US$50 million) through the issuance of 400,000,000 new fully paid ordinary shares, the Group has sufficient cash reserves to support the going concern position and will continue to advance the strategic partnership process to raise additional required project funding.

#### Note 2. Operating segments
2.1 Operating Segments

Segment results that are reported to the CODM include items directly attributable to a segment as well as those that can be allocated on a reasonable basis.

#### Description of segments
The Company operates predominantly as a mineral exploration and development company. The operating segments are based on the reports reviewed by the Managing Director for assessing performance and determining the allocation of resources and strategic decision making within the Group.

North America Represents activity in the US primarily in relation to Rhyolite Ridge and the Reno office. <br> Australia Represents head office expenditure, including ASX listing costs, employee benefits, exchange gains and losses and corporate assets (predominantly cash).

No provision for income tax is considered necessary in respect of the Company for the six months ended 31 December 2025. No recognition has been given to any future income tax benefit which may arise from operating losses not claimed for tax purposes (30 June 2025: nil). The Group has estimated tax loss positions across the Group as follows:

These amounts will only be obtained if:

● the Company and Controlled Entities derive future assessable income of a nature and of an amount sufficient to enable the benefit from the deductions for the losses to be
 realised.

● the Company and Controlled Entities continue to comply with the conditions for deductibility imposed by the law, and

● no changes in tax legislation adversely affect the Company and Controlled Entities in realising the benefit from the deductions for the losses, i.e. current tax legislation
 permits carried forward tax losses to be carried forward indefinitely.

● the accumulated tax losses in Australia may be carried forward and offset against taxable income in the future for an indefinite period, subject to meeting Australian tax rules
 around continuity of ownership or business continuity test.

● the accumulated tax losses in the USA can be carried forward and used to offset future taxable income for a period of 20 years from the year in which the losses were incurred, and
 losses will start to expire from the year 2027 onwards.

Ioneer Ltd is not part of an Australian tax-consolidated group. Current and deferred tax amounts (if any) are measured as a stand-alone taxpayer. There are no tax funding arrangements or tax sharing agreements in place.

The Group has additional tax value embedded in the Rhyolite Ridge exploration asset. Future deductibility is expected against anticipated assessable income from the Project once in production.

Plant and equipment assets are stated at cost less accumulated depreciation and any impairment in value. Depreciation is calculated on a straight-line basis over the useful life of the asset being between 1-4 years.

An item of plant and equipment is derecognised upon disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is included in the statement of profit and loss in the period the item is derecognised.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end adjusted prospectively, if appropriate. At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. Where an indicator of impairment exists, the Group makes a formal estimate of the recoverable amount. Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. Recoverable amount is the greater of fair value less costs to sell and value in use.

The Group recognises right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs incurred, and lease payments made at or before commencement date less any less incentives received. Unless the Group is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognised right-of-use assets are depreciated on a straight-line basis over the shorter of their estimated useful life and the lease term. Right-of-use assets are subject to impairment. The current lease terms range between 1-4 years (30 June 2025: 1-4 years).

#### Note 12. Non-current assets - exploration and evaluation
Exploration and evaluation expenditure incurred by or on behalf of the Group is accumulated separately for each area of interest. Such expenditure comprises net direct costs and an appropriate portion of related overhead expenditure but does not include general overheads or administrative expenditure not having a specific connection with a particular area of interest.

Exploration and evaluation costs in relation to separate areas of interest for which rights of tenure are current are brought to account in the year in which they are incurred and carried forward provided that:

&nbsp;&nbsp;&nbsp;&nbsp;● such costs are expected to be recouped through successful development and exploitation of the area, or alternatively through its sale;
 or

&nbsp;&nbsp;&nbsp;&nbsp;● exploration and/or evaluation activities in the area have not yet reached a stage which permits a reasonable assessment of the existence or otherwise of economically
 recoverable reserves.

The types of costs recognised as exploration and evaluation assets include costs to acquire the legal rights to explore in the specific area and costs incurred in respect of the search for mineral resources, determination of technical feasibility and the assessment of commercial viability of an identified resource, in accordance with AASB 6.

A Final Investment Decision (FID) to develop the Project is expected to be made after considering the following key factors: required permits are in place, engineering has reached construction ready status, adequate offtake agreements have been signed to underwrite any debt requirements, and the Project is funded through a mix of equity and debt. In order for FID and to attract funding, the Project will need to demonstrate technical feasibility and commercial viability.

Once FID has been taken, all past and future exploration and evaluation assets in respect of the area of interest are tested for impairment and transferred to the costs of development. To date, no development decision has been made.

The Directors assess at each reporting date whether there is an indication that an asset has been impaired and for exploration and evaluation costs carried forward whether the above carry forward criteria are met. No indicators of impairment have been identified as at 31 December 2025.

Note 12. Non-current assets - exploration and evaluation (continued)

When the above criteria do not apply or when the Directors assess that the carrying value may exceed the recoverable amount, the accumulated costs in respect of areas of interest are written off in the Statement of profit and loss and other comprehensive income.

| Additions - Rhyolite Rydge | 5850 |
| Exploration expenditure - noncore | 49 |
| Balance at 31 December 2025 | 209009 |

---

The above amounts represent costs of areas of interest carried forward as an asset in accordance with the accounting policy described above. The ultimate recoupment of exploration and evaluation expenditure in respect of an area of interest carried forward is dependent upon the discovery of commercially viable reserves and the successful development and exploitation of the respective areas or alternatively sale of the underlying areas of interest for at least their carrying value. Amortisation, in respect of the relevant area of interest, is not charged until a mining operation has commenced.

Exploration and evaluation costs carried forward relate primarily to the Rhyolite Ridge Lithium-Boron Project in Nevada, USA. Exploration and evaluation expenditure on all other tenements owned by the Company have been fully impaired where applicable.

The Company paid fees to establish a loan with the US Department of Energy (DOE). The fees will be amortised over the life of the loan. Amortisation begins after the first draw on said loan. The total loan amount is US$996 million (US$968 million in principal and US$28 million in capitalised interest during construction). The loan term is 20 years, and the interest rate is fixed from the date of each advance for the term of the loan at the applicable long-dated U.S. Treasury rate.

---

All financial liabilities are recognised initially at fair value net of directly attributable transaction costs.

After initial measurement, financial liabilities are subsequently measured at amortised cost. Current payables, other than lease liabilities, due to their short-term nature, are measured at amortised cost and are not discounted.

The current payables, other than lease liabilities, are unsecured and are non-interest bearing generally on 30-60 day terms. The carrying amounts approximate fair value.

At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payment includes fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating a lease, if the lease term reflects the Group exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognised as expense in the period on which the event or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Group uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in lease term, a change in the in-substance fixed lease payments or a change in the assessment to purchase the underlying asset.

| Provisions for employee benefits<br>| 303 | 462 |

---

Provisions are made for the Group's liability for employee benefits arising from services rendered by employees to the end of the reporting period. Employee benefits that are expected to be settled within one year have been measured at the amounts expected to be paid when the liability is settled. Employees' benefits payable later than one year have been measured at the present value of the estimated future cash outflows to be made for those benefits. In determining the liability, consideration is given to employee wage increases and the probability that the employee may satisfy vesting requirements. Those cash flows are discounted using market yields on high quality corporate bonds with terms to maturity that match the expected timing of cash flows.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Ordinary shares issued to employees upon vesting of performance
 rights

Ordinary shares are classified as equity. There are no restrictions on voting rights. On a show of hands every member present or by proxy shall have one vote and upon a poll each share shall have one vote. Where a member holds shares, which are not fully paid, the number of votes to which that member is entitled on a poll in respect of those part paid shares shall be fraction of one vote which the amount paid up bears to the total issued price thereof. They have the right to receive dividends as declared and, in the event of winding up of the Company, to participate in the proceeds from the sale of all surplus assets in proportion to the number of and amounts paid up on shares held.

Incremental costs directly attributable to the issue of new shares, options or rights are shown in equity as a deduction from the proceeds.

Management controls the capital of the Group in order to maintain a sustainable debt to equity ratio, generate long-term shareholder value and that the Group can fund its operations and continue as a going concern.

The Group is not subject to any externally imposed capital requirements.

During the 12 months ended 30 June 2025, the Company issued 30,057,807 shares as a consequence of Performance Rights vesting under the Equity Incentive Plan, nil shares as a result of options exercised, and 252,500,000 shares as a consequence of a capital raise.

During the six months ended 31 December 2025, the Company issued 20,701,784 shares as a consequence of Performance Rights vesting under the Equity Incentive Plan, nil shares as a result of options exercised, and 33,550,000 shares as a consequence of a capital raise.

#### Share schemes
The Company has two share schemes in operation:

● The Share Option Plan; and

● The Equity Incentive Plan

Note 18. Equity - issued capital (continued)

Under these plans, ordinary shares have been granted to senior executives, directors and employees and a number of consultants. Further details about the operation of these plans are set out in Note 26 'Share-based payments'. The Equity Incentive Plan is capable of issuing both options and performance rights. The pre-existing Share Option Plan will be phased out as existing options are issued or expire.

*Foreign currency reserve*

The foreign currency reserve is used to recognise exchange differences arising from the translation of the financial statements of foreign operations where the functional currency is different to functional currency of the parent entity. It is also used where exchange differences arise on the translation of monetary items which form part of the net investment in the foreign operation.

*Equity compensation reserve* 

The equity compensation reserve is used to recognise the value of equity-settled share-based payments provided to employees, directors and consultants. The fair value of such compensation is measured using generally accepted valuation methodologies for pricing financial instruments, and incorporates all factors and assumptions that knowledgeable, willing market participants would consider in setting the price. The fair value of instruments granted is recognised as an expense or capitalised if appropriate over the vesting period with a corresponding increase in equity.

There were no dividends paid, recommended or declared during the current or previous financial period.

#### Note 22. Financial instruments

#### Framework

#### Financial risk management
The Group has no financial assets where the carrying amount exceeds net fair values at balance date. The Group's receivables at balance date are detailed in Note 8 of this report.

The Group measures and recognises in the statement of financial position on a recurring basis certain assets and liabilities at fair value in accordance with AASB 13 Fair value measurement. The fair value must be estimated for recognition and measurement or for disclosure purposes in accordance with the following hierarchy:

---

| | |
|:---|:---|
| Level 1: | Quoted prices (unadjusted) in active markets for identical assets or liabilities; |
| Level 2: | Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and |
| Level 3: | Inputs for the assets or liabilities which are not based on observable market data (unobservable inputs). |

---

The carrying values of financial assets and liabilities of the Group approximate their value.

#### Classification and measurement
The Group is involved in activities that expose it to a variety of financial risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Credit risk

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Liquidity risk

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Capital management risk

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Market risk related to commodity pricing, interest rates and currency fluctuations.

The Board of Directors has overall responsibility for the establishment and oversight of the financial risk management framework of the group. Management is responsible for monitoring the financial risks.

The objective of the financial risk management strategy is to minimise the impact of volatility in financial markets on the financial performance, cash flows and shareholder returns. This requires the identification and analysis of relevant financial risks and possible impact on the achievement of the Group's objectives.

The Group does not undertake any hedging activities.

a. Credit risk

Credit risk is the risk of sustaining a financial loss as a result of the default by a counterparty to make full and timely payments on transactions which have been executed, after allowing for set-offs which are legally enforceable.

Credit risk arises from investments in cash and cash equivalents with banks and credit exposure to customers and/or suppliers. Receivables and cash and cash equivalents represent the Group's maximum exposure to credit risk. The Group is subject to a concentration of credit risk by having cash and cash equivalents held at one major Australian and one major U.S. bank. The Group regularly reviews its cash and cash equivalents as well as economic conditions, to determine whether adjustments to cash management are required to respond to changing conditions.

There are no trade receivables past due or impaired at the end of the reporting period (30 June 2025: nil).

b. Liquidity risk

Liquidity risk is the risk that the Group will not have sufficient liquidity to meet its financial obligations as they fall due.

The Group manages liquidity by continually monitoring forecast and actual cash flows and matching maturity profiles of financial assets and liabilities. Short-term and long-term cash flow projections are prepared periodically and submitted to the Board.

c. Capital management risk

The overriding objective of the Group's capital management strategy is to increase shareholder return whilst maintaining the flexibility to pursue strategic initiatives within a prudent capital structure.

The primary objective of the capital management policy is to ensure the Group maintains a strong credit profile and appropriate capital ratios to support the development of the Group's assets.

The Group manages its capital structure and makes adjustments to it in light of economic conditions.

d. Market risk

The method and assumptions remain consistent with prior periods.

#### Foreign exchange risk
Foreign exchange risk arises from the commercial transactions and valuations of assets and liabilities that are denominated in a currency that is not the entity's functional currency.

The Group has monetary items, including financial assets, denominated in currencies other than the functional currency of the entity. These are primarily US$ cash and intercompany loan balances in the holding company, which has a A$ functional currency. These items are restated to A$ equivalent at each period end, and the associated gain or loss is taken to the income statement. The US$ equivalent of these FX balances is reported in the group income statement as the functional currency financial statements are translated to US$ reporting currency for group reporting purposes.

The Group operates in a predominately US$ environment. The majority of the Group's financial position is managed and reported in US$. There is a foreign exchange exposure where the Group holds financial assets and liabilities in A$. These positions are summarised in the table below:

There is no impact to the current period loss on the above scenarios as the impact is taken to the foreign currency translation reserve.

#### Interest rate risk
The Company's exposure to interest rate risk, which is the risk that a financial instrument's value will fluctuate as a result of reasonable possible changes in the market interest rates, arise in relation to the Company's bank balance.

The Company does not engage in any hedging or derivative transactions to manage interest rate risk.

An increase of interest rates of 1% would result in $211,689 (30 June 2025: $255,326) decrease in the current financial period loss and an increase in interest income related to cash deposits. A decrease of interest rates of 1% would result in $211,689 (30 June 2025: $255,326) increase in the current financial period loss and a decrease in interest income related to cash deposits.

#### Commodity price risk
The Company is exposed to future commodity price risk. This risk arises from its activities directed at exploration and development of mineral commodities. If commodity prices fall, the share price for companies exploring for these commodities may be affected. The Company does not hedge its exposures.

The options and performance rights are anti-dilutive and have been excluded from the diluted EPS calculation below:

|  | **31-Dec-25**<br> **Cents** | **30-Jun-25**<br> **Cent**s |
|  Basic earnings per share | (0.17) | (0.41) |
|  Diluted earnings per share | (0.17) | (0.41) |

---

Basic EPS is calculated by dividing the profit for the period attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the period.

Diluted EPS is calculated by dividing the profit attributable to ordinary equity holders of the parent by the weighted average number of shares outstanding during the period plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. The effect of the dilution from options and rights on issue in the financial year would be 76,665,575 (30 June 2025: 64,922,144). The impact of the potential ordinary shares is treated as dilutive only when their conversion to ordinary shares would decrease EPS.

------

**Note 26. Share-based payments**

Share-based compensation is provided to employees via rights or options to acquire shares in the Company. As described in Note 19, the Company has two share schemes in operation. Under these plans, options or performance rights which may be converted into ordinary shares have been granted to non-executive directors, senior executives, employees and a number of consultants.

The cost of these equity-settled transactions is determined by reference to the fair value at the date at which they are granted. The fair value of the options granted is determined by using the Black & Scholes option pricing model. The fair value of the performance rights granted with time-based hurdles is determined using the 10-day VWAP of the Company's fully paid share capital, up to and including the date the performance rights are granted. For the component of performance rights based on company share price performance relative to a peer group, the fair value is determined by using a Monte Carlo model for the valuation of the performance rights subject to the relative performance hurdle and for the component of those rights subject to the business objectives, the valuation is equal to the value of the share price at grant date, multiplied by the number of shares anticipated to vest.

The cumulative expense recognised for equity-settled transactions at each reporting date reflects:

● the extent to which the vesting period has expired, and

● the number of awards that, in the opinion of the directors of the Company, will ultimately vest.

This opinion is formed based on the best available information at balance date. Where an equity-settled award is cancelled, the estimate is treated as if it had vested on the date of cancellation, and any expense not yet recognised for the award is recognised immediately.

Each plan is described in more detail below.

Note 26. Share-based payments (continued)

#### Equity Incentive Plan - established at the 2018 AGM
An Equity Incentive Plan was established following the AGM held on 31 October 2018. The purpose of the new Equity Incentive Plan ("the Plan") is to provide eligible persons the opportunity to participate in the growth and profits of the Company, and to attract, motivate and retain their services to promote the Company's long-term success.

Under the terms of the Plan, the Board may at its discretion invite eligible persons to participate in a grant of awards. An award may be either an option or performance right, to acquire a share in the capital of the Company in accordance with the Plan rules.

Options and performance rights issued under the terms and conditions and of the Plan are as follows:

#### Options

---

| | | |
|:---|:---|:---|
| **Type** | **Key terms** | **Expiry date** |
| Non-Executive Directors | The options were issued at an exercise price equal to VWAP for the Company's shares over the 10 trading days immediately before the date of the AGM. The options vest after 12 months and expire 60 months from the date of issue. | Tranche 2: 14 Nov 24 |

---

#### Performance rights - time-based

---

| | | |
|:---|:---|:---|
| **Type** | **Key terms** | **Expiry date** |
| Retention on Employment | Agreements with recruits including vesting after 3 years. Conditional on the achievement of continuing employment. | N/A |
| LTI grants | 42 months for 1 July 2025 (to transition to a calendar year performance period), thereafter 36 months. Conditional on the achievement of continuing employment. | N/A |

---

#### Performance rights - performance-based

---

| | | |
|:---|:---|:---|
| **Type** | **Key terms** | **Expiry date** |
| LTI grants | 42 months for 1 July 2025 (to transition to a calendar year performance period), thereafter 36 months | N/A |
|  | The Board will employ discretion in assessing Project results and determining vesting of performance units; below, at or above targets: **HSE**: Top quartile E, H&S and Community performance (compared to North American Mining Projects) **Construction**: Construction delivery compared to schedule at FID **Growth**: Measured and indicated LCE resource increased levels by 10% above July 2024 levels **Cost Control**: Project spend compared to budget at FID **Share price**: INR shareholder return compared to competitors |  |
|  | Unlike producing organisations with established operations that typically aim to deliver performance conditions tied to anticipated revenues, production levels and growth objectives, Ioneer has a single pre-production project with less certainty or control over key deliverables. Providing the Board with the discretion to assess the extent of delivery, the importance/value of the various targets delivered (or not) allows the ability to balance shareholder expectations and KMP reward, motivation and retention. |  |
|  | The Board will employ discretion in assessing Project results and determining the vesting of performance units; below, at or above targets (200%). |  |

Whilst there are a number of options and performance rights remaining on issue under the terms and conditions of previous schemes, no further options or rights will be issued under these pre-existing schemes which are described below.

#### Share Option Plan

 average of the last sale price of the Company's shares on the ASX at the close of business on each of the 5 business
 days immediately preceding the date on which the directors resolve to grant the options.

● The directors may limit the total number of options which may be exercised under the plan in any year.

Included within non-cancellable lease commitments is the lease of a neighbouring property to the Rhyolite Ridge Lithium-Boron Project. The Company has entered an option agreement to purchase this property. The cost of this discretionary purchase is excluded from the commitments disclosed above.

**Exploration licence expenditure requirements**

In order to maintain the Company's tenements in good standing with various mines departments and comply with the underlying option agreements, the Company will be required to pay annual claim maintenance fees. It is likely that the granting of new licenses and changes in license areas at renewal or expiry will change the expenditure commitment to the Company from time to time.

#### Note 30. Contingent assets and liabilities
**Settlement of Rhyolite Ridge**

The Company has entered an option agreement to purchase Rhyolite Ridge from Boundary Peak Minerals LLC on 3 June 2016. The Company has made 4 progress payments to Boundary Peak under the agreement. A final payment will fall due following Board making a 'decision to mine' the Rhyolite Ridge property. Once this decision is made, the Company is required under the terms of the contract to either:

&nbsp;&nbsp;&nbsp;&nbsp;● Pay Boundary Peak LLC US $3 million, or

&nbsp;&nbsp;&nbsp;&nbsp;● Issue shares (or a mix of both shares and cash) to Boundary Peak LLC, to the equivalent of US $3 million at a fixed exchange rate of USD $0.75 = AUD $1.00.

As at the date of this report, the decision to mine has not yet been made by the Company.

There are no other known contingent liabilities as at 31 December 2025.

**Note 31. Remuneration of auditors** 

During the financial period, the following fees were paid or payable for services provided by Ernst & Young, the auditor of the Company:

#### Mineral resource and ore reserves

#### 31 December 2025
Mineral Resources are reported in accordance with the Australasian Code of Reporting of Exploration Results, Mineral Resources and Ore Reserves (The Joint Reserves Committee Code – JORC 2012 Edition).

In December 2022, the United States Fish and Wildlife Service (USFWS) listed Tiehm's buckwheat as an endangered species under the Endangered Species Act (ESA) and has designated critical habitat by way of applying a 500 m radius around several distinct plant populations that occur on the Project site. Ioneer is committed to the protection and conservation of the Tiehm's buckwheat. The Project's Mine Plan of Operations, approved by the BLM in October 2024, has no direct impact on Tiehm's buckwheat and includes measures to minimise and mitigate for indirect impacts within the designated critical habitat areas identified.

The mineral resource pit shell used to constrain the October 2025 Mineral Resource estimate was not adjusted to account for any impacts from avoidance of Tiehm's buckwheat or minimisation of disturbance within the designated critical habitat. Environmental and permitting assumptions and factors have not been taken into consideration during modifying factors studies for the Project. The tonnes and grade within the avoidance polygons have not been removed from the Mineral Resources for the October 2025 estimate. Environmental and permitting assumptions and factors may be taken into consideration during future modifying factors studies for the Project. These permitting assumptions and factors may result in potential changes to the Mineral Resource footprint in the future.

Reserves are estimates of the amount of product that can be economically and legally extracted, processed and sold from the Group's properties under current and foreseeable economic conditions. The Group determines and reports reserves under the standards incorporated in the Australian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves, 2012 edition (the JORC code).

The determination of ore reserves includes estimates and assumptions about a range of geological, technical and economic factors including quantities, grades, production techniques, recovery rates, commodity prices and exchange rates. Changes in ore reserves impact the assessment of recoverability of exploration and evaluation assets.

Estimating the quantity and/or grade of reserves requires the size, shape and depth of ore to be determined by analysing geological data. This process may require complex and difficult judgements to interpret the data, Additional information about the Group's Reserves and Resources is set out in the 'Other Information' section.

The 2025 Ore Reserve is estimated to contain 265.5mt at 1,443ppm lithium (equivalent to 0.8% lithium carbonate) and 5,112ppm boron (equivalent to 2.9% boric acid), containing 2.0mt of equivalent lithium carbonate and 7.8mt of equivalent boric acid.

The Ore Reserves are based exclusively on HiB-Li mineralisation. The Mineral Resources are reported inclusive of the Ore Reserves. The changes to the previous ore reserve estimate primarily relate to:

&nbsp;&nbsp;&nbsp;&nbsp;● inclusion of low-boron lithium mineralisation in the Ore Reserve estimate for the first time,

&nbsp;&nbsp;&nbsp;&nbsp;● additional drilling completed,

&nbsp;&nbsp;&nbsp;&nbsp;● avoidance of Tiehm's buckwheat and Cave Springs in the mine plan, and

&nbsp;&nbsp;&nbsp;&nbsp;● additional ore streams to process plant.

The 266mt Ore Reserve provides the foundation for a very long mine life at the Rhyolite Ridge Project, with clear potential for expansion and extension further underpinned by the 549mt Mineral Resource.
