As part of this work, FinnCobalt recently took part in the 2nd EUMINDA Interregional Meeting (IR2) held in Western Macedonia, Greece, from 9–11 March 2026, together with representatives from regional authorities, research institutions, and industry across Europe.

Through EUMINDA, FinnCobalt has joined an important stakeholder cooperation network aimed at strengthening responsible mining practices through dialogue, knowledge exchange, and policy development.

International cooperation and knowledge exchange
A central part of the EUMINDA project is international information exchange and deepened cooperation between European regions. The initiative brings together public authorities, academia, industry, and civil society to address the long-term consequences of mining and to improve governance frameworks for mine closure and restoration.

For FinnCobalt and Eurobattery Minerals, participation reflects a core principle of responsible mining: responsibility extends beyond operations and includes the long-term restoration of mining sites.

“It might seem unusual to talk about restoration before mining operations have even started — but in modern responsible mining that is exactly how it should be,” said Ilari Kinnunen, Managing Director of FinnCobalt. “Closure and restoration must be part of the project design from day one. Through EUMINDA, we exchange practical experience with European partners while also learning from how different regions are addressing the legacy of past mining activities.”

From mining legacies to future-proof project design
EUMINDA focuses on addressing the environmental, social, and economic legacies of historical mining, while supporting regions in developing more effective approaches to restoration and post-mining land use.

Eurobattery Minerals applies these lessons proactively by integrating closure planning, rehabilitation, and restoration into project development from the earliest stages. This includes planning for progressive restoration during operations and ensuring that sites are environmentally safe and suitable for future use.

Strong regional cooperation in North Karelia
FinnCobalt participates in the project through the Regional Council of North Karelia, as part of a broad regional stakeholder network including authorities, academia, industry, and civil society.
The region has strong expertise in addressing environmental impacts from mining and advancing circular solutions, and the cooperation contributes to the development of a roadmap for a responsible mineral economy in North Karelia.

“Europe’s sustainability transition and industrial competitiveness both depend on secure access to responsibly produced raw materials,” said Roberto García Martínez, CEO of Eurobattery Minerals. “For mining projects to earn public trust and attract long-term investment, responsibility must extend across the entire life cycle — including closure and restoration. Initiatives like EUMINDA strengthen the policy environment needed for modern European mining to develop with credibility and transparency.”

About EUMINDA

The Board of Directors has conducted a comprehensive review of the Company’s project portfolio and concluded that Eurobattery Minerals’ human, technical, and financial resources must be concentrated on the two assets with the greatest value-creation potential for shareholders: the San Juan tungsten project, located in A Gudiña, Galicia (Spain), and the Hautalampi battery mineral project which lies in Outokumpu, North Karelia (Finland).

In this context, the Company has decided not to proceed with the development of the Corcel Minerals project (located in northwestern Spain). Following a thorough assessment, the Board considers that current market conditions and the Company’s strategic priorities do not justify the allocation of further resources to this project at this time. As part of the strategic portfolio review, the Company will update the valuation of its assets in the relevant financial statements accordingly.

The financial impact of this decision on the Company’s balance sheet is expected to be limited. Any accounting adjustments will be reflected in the Company’s financial statements in accordance with applicable accounting standards.

“This decision reflects a disciplined approach to capital and resource allocation. By concentrating our efforts on our two core assets, we are positioning Eurobattery Minerals to deliver maximum value for our shareholders,” says Roberto García Martínez, CEO of Eurobattery Minerals AB

Such requests are a standard and expected part of the permitting process, reflecting the thorough and transparent regulatory framework governing mining projects in Finland and across the EU. Similar clarification rounds are a natural continuation of the review process following the submission of the EPA in April 2024 and the supplementary documentation provided in July 2025.

The Company has initiated an internal review of the request and is working closely with its specialized technical consultants and engineering advisors to assess the scope of the additional information required. Eurobattery Minerals will provide the requested clarifications and any supporting documentation in due course, following a thorough assessment of the authority’s request.

The permitting process is advancing in accordance with the regulatory procedure applicable to major mining projects in Finland, and the Company remains fully committed to providing comprehensive and high-quality responses to the authority’s requests.

The Hautalampi project, located in the historic Outokumpu mining region in Finland, is being developed as a future European source of responsibly produced nickel, cobalt and copper—critical raw materials for the sustainability transition. FinnCobalt has applied for Strategic Project designation under the EU Critical Raw Materials Act (CRMA), underscoring the project’s European strategic relevance.

“Metallurgical testwork is a critical step in transforming a mineral resource into a viable mining project,” said Roberto García Martínez, CEO of Eurobattery Minerals. “By working with SLR, a globally recognised and highly experienced technical partner, we are strengthening the technical foundation of the San Juan project and moving forward in a structured and disciplined way.”

The bulk sample, totalling approximately 1,000 kilograms of wolfram-bearing material, will be processed at SLR’s laboratories in Truro, Cornwall — a historic mining region. SLR has extensive expertise in mineral processing and metallurgical testing.

The test programme, expected to run over approximately five months — with results expected in Q3 2026 — will involve a comprehensive evaluation of the ore’s processing characteristics. This includes crushing and classification into different size fractions, followed by detailed analysis of grade distribution to determine how the wolfram mineralisation is hosted within the material.

A series of gravity-based metallurgical tests will be conducted, including cyclone classification, spiral separation and shaking table tests. These tests will generate multiple output streams — including concentrate, intermediate fractions, and tailings — enabling a detailed assessment of recovery performance across different particle sizes and processing conditions.

The results from the programme will form the basis for the final design of the process flowsheet and the future processing plant, supporting both technical optimisation and responsible resource use. This represents a key milestone in the project’s development path: the metallurgical data will feed directly into the final engineering design work being led by Minepro, enabling the Company to advance towards a detailed process design, a critical prerequisite for the construction and commissioning of the San Juan processing plant.

“Every ore body behaves differently and understanding that behaviour is essential for designing an efficient and reliable processing solution,” said Agne Ahlenius, Managing Director of Tungsten San Juan. “This work will allow us to define a process that is tailored to our specific conditions in Galicia, combining strong technical performance with a responsible approach to resource management.”

Eurobattery Minerals continues to advance the San Juan tungsten project as part of its broader strategy to contribute to Europe’s secure and responsible supply of critical raw materials, essential for the sustainability transition and for strengthening European industrial resilience. San Juan is currently under review for designation as a Strategic Project under the EU Critical Raw Materials Act (CRMA), a status that would further underline the project’s significance for European supply chain security and industrial competitiveness.

Background

• On 27 November 2024, the Company issued convertible bonds to Fenja through a private placement amounting to SEK 4,000,000.
• In September 2025, Fenja converted SEK 1,500,000 of the total amount, remaining 2,500,000 SEK outstanding.
• As previously announced on 23 February 2026, a further SEK 1,250,000 was converted, remaining 1,250,000 SEK outstanding.
• Fenja has now elected to convert the entirety of its remaining holding – to the contractually agreed nominal amount of SEK 1,250,000 – thereby fully converting all outstanding convertible bonds and reducing the balance to zero.

Fenja is converting the entirety of its remaining holding into newly issued shares at a conversion price of SEK 0.09 per share (recalculated following the company’s completed rights issue). Following this conversion today, Fenja holds no further convertible instruments in the company.

“Becoming fully debt-free is a defining moment for Eurobattery Minerals, and the timing could not be more significant. We are now entering an active phase of development across our project portfolio, and in particular at San Juan, our tungsten project in Galicia, Spain, where engineering work is well advanced. A clean balance sheet, free of any convertible obligations, gives us a stronger foundation from which to advance our projects, engage with partners and financiers, and capitalise on the growing European demand for domestically sourced critical minerals,” says Roberto García Martínez, CEO of Eurobattery Minerals AB.

The key terms and effects of the conversion

• Converted nominal amount: SEK 1,250,000
• Number of newly issued shares: 13,888,889
• Total number of shares after the conversion: 976,258,262
• Remaining convertible debt: SEK 0 (none)

Strategic significance
The settlement of all convertible liabilities is an important step in Eurobattery Minerals’ financial consolidation. This milestone is particularly meaningful as the company accelerates the development of its flagship San Juan tungsten project in Galicia, Spain, and advances its broader portfolio of critical raw materials projects. The company now enters this phase with a structurally cleaner balance sheet, providing several key advantages:

• A simpler and stronger balance sheet, free from convertible liabilities and the uncertainty regarding dilution that these entail.
• Greater strategic flexibility to implement value-creating initiatives, including project development and potential partnerships, from a financially strong position.
• Sends clear signals regarding the company’s disciplined approach to capital structure and financing.

Dilution effect
The conversion entails the issue of 13,888,889 new shares, corresponding to a dilution of approximately 1.5 per cent in relation to the total number of shares following the conversion (976,258,262 shares). Both this conversion and the preceding first tranche conversion were previously communicated to the market. Following this transaction, the company has no convertible instruments or similar dilutive instruments outstanding.

Eurobattery Minerals AB (publ)
BOARD OF DIRECTORS

A strategic asset at a critical moment for Europe
Tungsten is classified as one of the European Union's most strategically sensitive critical raw materials, with global supply chains currently dominated by a single country. The San Juan tungsten project represents a rare, advanced European primary wolfram asset, and the Company is committed to bringing it into production as swiftly and responsibly as possible.

“This is an important step forward for our tungsten project in Galicia,” said Roberto García Martínez, CEO of Eurobattery Minerals. “Developing the processing infrastructure is essential to unlocking the value of the San Juan deposit. By working with Minepro, we are ensuring that the plant is designed specifically for the characteristics of the ore and built with a flexible architecture that supports the long-term development of the project. Responsibly produced tungsten in Europe will be increasingly important for Europe’s industrial resilience and technological competitiveness.”

A best-in-class engineering partner
Minepro brings decades of hands-on experience in mineral processing plant design and metallurgical optimisation, with a strong track record on comparable European projects. Their mandate covers the complete engineering scope of the plant — covering process, mechanical, electrical, and instrumentation & control disciplines — as well as the definition and supervision of a comprehensive metallurgical test programme to be carried out at an accredited external laboratory.

By running engineering and a metallurgical reconfirmation program simultaneously across an approximately 20-week programme, the Company is taking an accelerated path to production without compromising technical rigour or the quality of the final plant design.

Plant design and path to production
The processing plant will be designed to produce a high quality and marketable tungsten concentrate through a gravimetric concentration circuit optimised for the ore characteristics at San Juan. The plant will commence operations at an initial throughput of 10 t/h, with capacity designed to scale progressively — a capital-efficient approach well suited to the Company's development strategy.

Alongside gravimetric concentration, the test programme will evaluate additional beneficiation stages — to ensure the plant delivers a concentrate fully meeting commercial specification. Construction, installation and commissioning will be contracted separately upon completion of the engineering phase, with plant operations targeted to commence in Q1 2027.

“Building a processing plant adapted to the specific conditions of the San Juan deposit is a key milestone for the project,” said Agne Ahlenius, Managing Director of Tungsten San Juan S.L. “Our goal is to develop a modern operation that combines technical efficiency with strong environmental and safety standards. The modular design also gives us flexibility to scale production in a responsible way as the project evolves.”

As announced previously in 2025, the Company had planned to conduct metallurgical testwork and pilot plant design together with Advanced Mineral Processing S.L. (AMP). However, due to circumstances outside the Company’s control, that collaboration could not proceed as originally planned. Eurobattery Minerals has therefore decided to move forward with Minepro to continue advancing the technical development of the project.

About Minepro Solutions S.L.
Minepro Solutions, S.L. is a specialist mineral processing engineering company with extensive experience in the design, engineering and commissioning of processing plants across a broad range of mineral commodities. Minepro is recognised for its rigorous, fit-for-purpose approach to plant engineering and metallurgical test programme management.

The 2025 Sustainability Report outlines how responsible mining is integrated into all aspects of the Hautalampi project. Built around three pillars — environment, people, and community — the report describes environmental monitoring, biodiversity protection, water stewardship, health and safety practices, local cooperation, and governance standards. The work is aligned with the Towards Sustainable Mining (TSM) framework.

“We want to demonstrate clearly and transparently how responsible mining is implemented in practice,” says Ilari Kinnunen, Managing Director of FinnCobalt. “For us, sustainability is not a separate initiative — it is the foundation of how we develop the Hautalampi project and engage with the local community.”

Key highlights from 2025 include zero workplace accidents, comprehensive groundwater monitoring supported by a three-dimensional groundwater model, an updated Natura 2000 assessment for Lake Sysmäjärvi, aquatic ecosystem surveys in the Ruutunjoki River, and active community engagement through regular public meetings. The report also details progress on reducing the project’s future carbon footprint, including preparations for CO₂-free energy and a fully electrified mining fleet.

“The publication of this Sustainability Report marks another important step forward for the Hautalampi project,” says Roberto García Martínez, CEO of Eurobattery Minerals. “We are making steady, tangible progress — from environmental approvals and groundwater modelling to community engagement and carbon reduction planning. Each milestone brings us closer to production and reinforces our position as a credible European source of responsibly produced battery minerals. This is a project that is moving forward, and we are building it the right way.”

In parallel, FinnCobalt has fully redesigned the “Environment and Responsibility” section of its website. Previously limited to technical documentation in Finnish, the section now offers clear, bilingual content covering environmental monitoring results, occupational health and safety, community engagement activities, and the company’s participation in the TSM Finland mining responsibility system.

FinnCobalt’s sustainability program is aligned with the TSM protocol and the UN Sustainable Development Goals. Throughout 2026, the company will continue to refine its action plans, with priorities including CO₂ emissions reduction, water management, biodiversity protection, and strengthened community dialogue.

Proposed decision in brief:

The Board’s proposal for a directed issue of shares (item 7)
The Board of Directors proposes that the company’s Chief Executive Officer, Roberto Garcia Martinez, shall receive his outstanding liabilities through the wholly owned company Nazgero Consulting Services Ltd (“Nazgero”) in the form of shares.

Accordingly, the board of directors has decided to propose an issue of 53,295,593 shares. In order to effect the delivery of shares, the board of directors proposes that the general meeting resolves on a directed new issue of shares to Nazgero on the following terms and conditions.

The board of directors proposes that the general meeting resolves on a directed new issue of not more than 53,295,593 shares, entailing an increase in the share capital of not more than SEK 72,924.1642982568. The issue shall otherwise be governed by the following terms and conditions:

1. In deviation from the shareholders’ pre-emption rights, the new shares may only be subscribed for by Nazgero Consulting Services Ltd.
2. The subscription price per share shall amount to SEK 0.09. The share premium shall be transferred to the unrestricted share premium reserve.
3. Subscription for the shares shall take place through set-off no later than three weeks from the date the general meeting has resolved on the new issue. The board of directors is entitled to extend the subscription period.
4. Payment for the shares subscribed for shall be made through set-off of a claim consisting of accrued consulting fees. The board of directors is entitled to extend the time for payment.
5. The new shares entitle the holder to dividends for the first time at the record date for dividends that falls closest after the new shares have been entered in the share register.

The reason for the deviation from the shareholders’ pre-emption rights is the need to be able to pay remuneration to Nazgero in a liquidity-efficient manner. The subscription price of SEK 0.09 per share is identical to the subscription price in the directed issue to external investors, which has been determined through arm’s length negotiations. The board acknowledges that the subscription price represents a significant discount to the current market price. The board has nevertheless concluded that the subscription price is justified for the following reasons: (i) the CEO receives shares on exactly the same terms as the external investors in the Directed Issue, and there is no preferential treatment; (ii) Fenja Capital II A/S, an independent external holder of convertible instruments, converted at a price of SEK 0.09 per share on 23 February 2026, confirming that the price level has been accepted by an independent third party; (iii) the issue relates to a debt conversion, not a purchase of shares at a discounted price – the CEO has already rendered services to the Company and is now electing to convert those claims into equity at a price consistent with third-party transactions; and (iv) the subscription price is consistent with, or at a premium to, subscription prices in the Company’s capital raises over the past twelve months: the rights issue of September 2025 (SEK 0.06 per share), the exercise of warrants of series TO6 in May 2025 (SEK 0.09 per share), and the Fenja Capital conversion of February 2026 (SEK 0.09 per share).

The maximum dilution effect as a result of the new issue of shares proposed under this item 7 amounts to approximately 6 per cent based on the number of outstanding shares in the Company at the time of this notice.

Roberto Garcia Martinez has not participated in the preparation of the proposal under this item 7.
A valid resolution requires the approval of shareholders representing at least nine-tenths of both the votes cast and the shares represented at the general meeting.

Personal data
Personal data obtained from the share register maintained by Euroclear Sweden AB, notification of attendance at the meeting and information about representatives, proxies and assistants will be used for registration, preparation of the voting list for the meeting and, where applicable, minutes of the meeting.

Other
