Page 2 of 13 Bannerman Managing Director and Chief Executive Officer, Gavin Chamberlain, commented: “The June quarter further demonstrated the discipline and methodical approach being applied to the development of Etango. Early works continue to track to overall schedule and budget, reflecting the capability of our project team and contractors, and the strong focus on execution risk that underpins every stage of the development programme. “At the same time, we continue to make good progress towards completion of the CNOL strategic investment and joint venture transaction. Our engagement with CNOL has been highly constructive and collaborative, reinforcing the strong alignment between the parties and our shared commitment to the successful development of Etango. “With the project footprint increasingly visible on site, engineering and infrastructure activities advancing to plan, and a clear pathway towards transaction completion and FID, Etango continues to build momentum from a position of strong project readiness.” CNOL Strategic Financing Transaction background During the March quarter, Bannerman executed landmark binding investment subscription and joint venture documentation with CNOL for the funding, development and operation of the Etango Project (refer Bannerman ASX release dated 12 February 2026, Etango Strategic Financing with Global Nuclear Utility, CNNC). CNOL is a subsidiary of Shenzhen Stock Exchange listed China National Uranium Corporation (CNUC) and part of leading integrated global nuclear utility, China National Nuclear Corporation (CNNC). The transaction provides Bannerman with a clear, debt-free pathway to fund construction of Etango, reducing financing risk while preserving meaningful offtake and financial flexibility. It also establishes a strongly aligned long-term partnership with CNOL, supported by pro rata project funding and market-based offtake for 60% of production with a Tier-1 nuclear industry partner. The binding documentation with CNOL provides for: 1. Formation of an incorporated joint venture through Bannerman’s UK subsidiary, Bannerman Energy (UK) Ltd (JVCo), by way of CNOL’s subscription for newly issued shares in JVCo, resulting in JVCo ownership of 55% by Bannerman and 45% by CNOL upon completion. JVCo holds a 95% interest in the Etango Project. 2. Initial investment of US$294.5 million by CNOL into JVCo upon completion. 3. Provision for additional investment by CNOL of up to US$27 million upon completion, to reimburse Bannerman for CNOL’s 45% share of project-related expenditure incurred between 1 July 2025 and completion. These funds will be paid directly to Bannerman and will therefore be available to it (including to meet its 55% share of any future funding and/or working capital requirements). 4. Life-of-mine offtake entitlement for CNOL covering 60% of actual production from Etango. The key agreements supporting the transaction are: • Share Subscription Agreement (SSA), which details the mechanics of CNOL’s investment into JVCo; and • Shareholders Agreement (SHA), which will be executed upon completion of the share subscription and sets out the governance principles for JVCo (and its subsidiaries) as well as key offtake terms. A full-form offtake agreement (based on the binding offtake terms set out in the SHA) is to be documented post-completion and prior to the commencement of production from Etango.

Page 3 of 13 Progress update During the June quarter, Bannerman and CNOL worked collaboratively through the established transaction Steering Committee, supporting coordination across technical, commercial and governance workstreams ahead of completion. Engagement with relevant regulatory authorities and other stakeholders also continued. Completion of the SSA is subject to satisfaction (or waiver, as applicable) of the following CPs (with the current status of these CPs, as endorsed by the Steering Committee, also noted): • Completion of filings with the relevant Chinese government authorities (NDRC and Ministry of Commerce) and foreign exchange registration (in progress); • CNUC shareholder approval (satisfied); • Receipt of clearance from the Namibian Competition Commission (satisfied); • Requisite amendment to the OEF funding agreement to reflect new proportionate ownership of JVCo (satisfied); • Execution of key Etango Project infrastructure supply contracts (satisfied); and • Customary conditions that any other regulatory approvals jointly determined by the parties to be required are obtained and no legal or regulatory restraint being issued or made by any court preventing completion of the transaction (satisfied and/or no restraint). Satisfaction of residual CPs followed by transaction completion is expected during Q3 2026. In parallel, the Etango early works programme continued to advance during the quarter (see section below), maintaining project momentum. Site early works, detailed engineering, procurement and long lead infrastructure activities continued in accordance with the approved development schedule, supporting Etango’s readiness for targeted FID following completion of the CNOL transaction. Etango Uranium Project (Bannerman 95% ownership) Ongoing safety focus The contractor workforce on site exceeds 560 personnel across four Namibian contractors delivering earthworks, civil construction, aggregate production and infrastructure works. During May 2026, the Bannerman Mining Resources Namibia team and its contract partners achieved the significant milestone of one million LTI-free hours on the Etango Project. This achievement extends Bannerman's unbroken LTI-free record and reflects the strong safety culture embedded across all project activities. Safety leadership initiatives, workforce engagement programmes and ongoing awareness campaigns continue to reinforce Bannerman’s proactive approach to risk management and safe work practices. Long lead construction activities and purchase orders Manufacturing instructions: Long lead items Five additional instructions to commence manufacturing of mechanical items for the dry plant area were issued during the quarter. These orders were previously placed to secure vendor data for design purposes. The manufacturing and delivery of this equipment is aligned with current schedule requirements.

Page 4 of 13 Bulk earthworks The bulk earthworks contract continues to advance in line with schedule and budget expectations and stands at approximately 92% complete. Activities remain concentrated on the heap leach pad and associated process solution ponds, while work on the wet plant terraces has continued to expand. As these areas become increasingly defined, the overall project footprint is becoming clearly visible across the site. Figure 1: In addition to the heap leach pad earthworks, works have continued on the wet plant terraces and solution ponds. Heap leach pad drainage aggregate Production of heap leach drainage aggregate continues to deliver material that meets required specifications. Blasting, crushing and screening by local Namibian contractor, Tulela Mining & Construction (Pty) Ltd, remains well coordinated with the broader construction programme and stockpiles continue to build ahead of future placement on the heap leach pad. Aggregate production has reached approximately 29% of total volume required and remains an important enabling activity supporting future heap leach pad construction. Phase 1 and Phase 2A concrete contracts Concrete construction activities by local Namibian contractor, K Neumayer Civil Contractors (Pty) Ltd, continue across key dry plant infrastructure areas, with major processing facilities now beginning to take shape across the Etango Project site. The Phase 1 contract covers construction of the primary crusher structure, which forms the first stage of the processing circuit. Works have continued to advance with foundations complete and structural concrete elements progressing above ground level.

Page 9 of 13 Offtake marketing Bannerman’s marketing strategy is designed to systematically build a portfolio of uranium sales agreements with leading counterparties. This measured approach supports the Company’s long-term objectives by balancing price exposure and revenue stability, optimising pricing opportunities, and ensuring Bannerman remains agile and responsive to shifting market dynamics. As announced in February 2026, and outlined above, the Company has agreed material terms for a cornerstone offtake arrangement with CNOL, under which CNOL will purchase 60% of Etango production on arm’s-length, market-based pricing terms. CNOL offtake volumes are priced based on a combination of prevailing spot and term uranium price indices. Payment terms are considered to be significantly superior to market standards and are expected to reduce required working capital. Bannerman will retain responsibility for marketing the remaining 40% of production, which it intends to place progressively over time with a diversified group of counterparties, under strict confidentiality ring-fencing arrangements. This approach is consistent with the Company’s expectation of continued strengthening in term uranium market fundamentals, supporting the disciplined layering of additional offtake commitments. Bannerman actively engages with a broad range of utilities, financial institutions, traders, and other key market participants in relation to this residual offtake, building on the initial offtake agreements executed with Tier 1 utilities in September 2025. Committed expenditure and project schedule The Company continues to take a disciplined approach to project expenditure. As of 30 June 2026, Bannerman has completed approximately A$69.31 million of Etango early works programs. Early works commitments (as at 30 June 2026) total a further approximately A$36.2 million. All key workstreams remain on track for a targeted positive FID on Etango promptly following completion of the CNOL strategic investment and joint venture transaction. Corporate Strong liquidity Bannerman’s cash balance at 30 June 2026 was A$53.1 million (31 March 2026: A$69.9 million), with no debt (other than typical creditor balances) or convertible instruments. As part of its treasury and future sales risk management activities, Bannerman also holds liquid assets, in the form of units in the Sprott Physical Uranium Trust (SPUT). At 30 June 2026, the market value of liquid assets held by Bannerman was approximately A$11.5 million. Bannerman also holds approximately 101.3 million shares in Namibia Critical Metals Inc (TSXV:NMI), owner of the Lofdal Heavy Rare Earth Project in Namibia. At 30 June 2026, this shareholding had a market value of approximately A$22.7 million. 1 Project expenditure is incurred by the Company’s Namibian subsidiary, which has a Namibian dollar (NAD) functional currency, with the majority of costs denominated in NAD. These amounts are translated into Australian dollars (AUD) for reporting purposes. Accordingly, reported AUD amounts are subject to exchange rate movements and may not directly reflect underlying activity during the period. For the March quarter, the movement in reported expenditure includes an exchange impact of approximately A$1.7m.

Page 10 of 13 Cashflow disclosures Total property, plant and equipment expenditure for the quarter was A$10.4 million, which relates predominantly to the Etango early works programs. Total exploration and evaluation expenditure for the quarter was A$8.2 million, primarily directed towards detailed design and early construction works for Etango. For the purpose of item 6.1 of Appendix 5B, aggregate payments during the quarter to related parties totalled A$320,237, comprising directors’ fees and salaries. Bannerman Mining Resources (Namibia) (Pty) Ltd finalised a VAT refund for the September to December 2025 quarter of N$51.5 million (approx A$4.4 million) which is reflected as a positive cash inflow of A$1.242 million under Administration and Corporate Costs for the quarter. Cancellation and issue of securities During the quarter, the Company issued the following securities: § Exercise of Options: 79,095 unlisted Zero Exercise Price Options (ZEPOs) were exercised for NIL consideration in accordance with the terms of the EIP. Issued securities At the date of this report, the Company has 207,811,582 fully paid ordinary shares and 2,642,365 unlisted options on issue. The options are subject to various performance targets and continuous employment periods. Uranium Market2 Spot U₃O₈ prices remained relatively stable during the June 2026 quarter, opening at US$84.50/lb and trading within a range of US$83.50/lb to US$87.00/lb. The spot price closed the quarter at US$85.25/lb, with a quarterly average price of US$85.67/lb. The long-term price reference continued to strengthen over the quarter, increasing from US$93.00/lb at 31 March 2026 to US$97.00/lb at 30 June 2026. This movement reinforces the distinction between a broadly range bound spot market and a firmer long-term contracting market, where utility procurement remains focused on security of supply, counterparty reliability, jurisdiction and reduced exposure to future spot price volatility.

Page 12 of 13 ABOUT BANNERMAN ENERGY (ASX:BMN, NSX:BMN, OTCQX:BNNLF) Bannerman Energy Ltd is a uranium development business listed on the Australian and Namibian stock exchanges and traded on the OTCQX Market in the US. Its flagship asset is the advanced Etango Uranium Project located in the Erongo Region of Namibia. Etango has benefited from extensive exploration and feasibility activity over the past 15 years. The Etango tenement possesses a globally large-scale uranium mineral resource1. In December 2022, a Definitive Feasibility Study (DFS)2 was completed on the Etango-8 Project, confirming to a definitive-level the strong technical and economic viability of conventional open pit mining and heap leach processing of the Etango deposit at 8Mtpa throughput (for average annual output of 3.5 Mlbs U3O8). In March 2024, a scoping study3 demonstrated the capacity to expand annual production to 6.7 Mlbs U3O8. Etango’s advanced credentials are further highlighted by the construction and multi-year operation of the Etango Heap Leach Demonstration Plant, which comprehensively de-risked the conventional acid heap leach process to be utilised on the Etango ore. All environmental approvals have been received for the proposed Etango mine and external mine infrastructure, based on a 12-year environmental baseline. Bannerman was awarded the Mining Licence for Etango in December 2023 and is progressing all key project workstreams towards a targeted positive Final Investment Decision (FID) in parallel with strengthening long-term uranium market fundamentals. Namibia is a premier uranium investment jurisdiction, with a 45-year history of uranium production and export, excellent infrastructure and support for uranium mining from both government and community. As the world’s third largest producer of uranium, Namibia is an ideal development jurisdiction boasting political stability, security, a strong rule of law and an assertive development agenda. The Bannerman team has ample direct experience in the development, construction and operation of uranium projects in Namibia, as well as extensive links into the downstream nuclear power industry. Bannerman has long established itself as an Environmental, Social and Governance (ESG) leader in the uranium and nuclear energy sector. It is also a leader within Namibia on social development and community engagement and exercises best-practice governance in all aspects of its business. This was recognised with receipt of the 2023 African Mining Indaba’s ESG Award for Community Engagement. 1 and 2.
