Important Notice

Coinsilium Group Limited (“Coinsilium” or “the Company”) holds part of its reserves in Bitcoin through its wholly owned Gibraltar-based subsidiary, Forza (Gibraltar) Limited (“Forza”), which is responsible for managing the Company’s Bitcoin treasury.

The Financial Conduct Authority (“FCA”) regards digital assets such as Bitcoin as high-risk and speculative, with potential for extreme price volatility. An investment in Coinsilium Group Limited is not an investment in Bitcoin, either directly or by proxy. Coinsilium holds a range of assets, including equity interests in companies operating within and beyond the blockchain sector, and maintains a diversified portfolio of strategic investments across the digital asset space. This structure provides broader exposure beyond Bitcoin. The Company’s exposure to Bitcoin forms part of its broader capital allocation strategy.

Coinsilium is not authorised or regulated by the FCA. While the Board of Directors considers Bitcoin to be an appropriate long-term reserve asset, prospective and existing investors should be aware of the associated risks. There is no certainty that the Company will be able to realise its Bitcoin holdings at expected valuations, and the financial performance of the Company may be affected by movements in the price of Bitcoin. As a result of the Company’s exposure to Bitcoin, the market value of Coinsilium shares may also experience significant fluctuations, and the value of investments can go down as well as up.

The decision to allocate capital into Bitcoin, facilitated through the Company’s dedicated treasury management structure, Forza, reflects a strategic view of Bitcoin as a long-term reserve asset. This approach is underpinned by over a decade of experience operating in the digital asset sector.

In accordance with the Aquis Framework for Issuers pursuing Cryptocurrency Strategies, the Company is required to draw to shareholders’ attention particular risks relating to cryptoassets. The Company’s exposure to the cryptoasset sector exposes the Company to a number of significant risks, including, but not limited to:

Volatility of the price of Digital Assets, including but not limited to Bitcoin

Digital assets, including but not limited to Bitcoin, are subject to extreme price volatility, with values capable of rising or falling sharply over short periods. This volatility can have a material adverse effect on the company’s financial position and results. Investors should be aware that the value of the Company’s digital asset holdings may fluctuate significantly, leading to substantial losses. There is no guarantee that the Company will be able to realise its digital asset holdings at expected valuations.

Regulatory Uncertainty

The regulatory environment for cryptoassets, including Bitcoin, is evolving and remains uncertain in many jurisdictions. Changes in laws or regulations could adversely affect the Company’s ability to hold, trade, or use Bitcoin. There is a risk that future regulatory action could require the Company to divest its Bitcoin holdings or restrict its operations. Non-compliance with applicable regulations could result in penalties or reputational harm.

Security and Custody Risks

The Company’s cryptoasset holdings, including those in Bitcoin, are subject to security risks, including cyberattacks, hacking, and theft. Despite using third-party, institutional-grade custodians, there is no absolute guarantee against loss or misappropriation. Any security breach could result in the partial or total loss of the Company’s cryptoassets. The Company may have limited recourse to recover lost or stolen assets.

Liquidity Constraints

Cryptoasset markets, including Bitcoin, may experience periods of illiquidity, which could impact the Company’s ability to sell its holdings quickly or at favourable prices. Market disruptions, technological failures, or a lack of counterparties may further constrain liquidity. In such scenarios, the company may be forced to accept lower prices or delay transactions. This could adversely affect the Company’s financial performance.

Reputational Risks

The association with the cryptoasset sector, including Bitcoin, may expose the Company to reputational risks. Negative perceptions arising from links to illicit activity, cybercrime, or regulatory scrutiny could impact stakeholder confidence. Adverse media coverage or public opinion may affect the company’s relationships with investors, customers, or partners. Reputational damage could have long-term consequences for the business.

Market Acceptance and Adoption

The value and utility of cryptoassets, including Bitcoin, depends on its continued acceptance by users, merchants, and investors and its perception as a store of value. Any decline in adoption or negative trends in public perception could reduce demand and depress prices. Technological changes or superior alternatives could also undermine bitcoin’s position. The Company’s exposure to cryptoassets, including Bitcoin, may therefore become less valuable or obsolete.

Counterparty Risk

The Company relies on third-party custodians and service providers to safeguard its cryptoassets. There is a risk that such counterparties may fail, become insolvent, or act negligently. In such cases, the Company could suffer financial loss or face difficulties in accessing its assets. The effectiveness of risk mitigation depends on the reliability and integrity of these third parties.

Legal and Tax Risks

The legal and tax treatment of cryptoassets is complex and subject to change. Uncertainty regarding classification, reporting obligations, or tax liabilities could result in unforeseen costs or compliance issues. The Company may need to adapt to new legal interpretations or regulatory guidance. Failure to comply with applicable laws could result in penalties or operational restrictions.

Technology and Operational Risks

Cryptoassets, including Bitcoin, rely on complex technological infrastructure, including blockchain networks and cryptographic protocols. System failures, software bugs, or protocol changes could disrupt the company’s ability to access or transfer its holdings. Operational risks also include human error and inadequate internal controls. Such risks may lead to financial loss or operational disruption.

Environmental and ESG Risks

Cryptoasset mining and transaction processing are energy-intensive and have raised environmental, social, and governance (“ESG”) concerns. Negative perceptions around environmental impact could affect the company’s ESG ratings or investor appetite. Regulatory measures targeting environmental sustainability could restrict or penalise cryptoasset-related activities. The Company may face increased scrutiny from stakeholders on its ESG performance.

Concentration Risk

A significant portion of the Company’s assets may be concentrated in cryptoassets, including Bitcoin, exposing it to heightened risk from adverse market movements. Lack of diversification increases vulnerability to price shocks or sector-specific developments. Concentration risk may also amplify the impact of regulatory or technological changes. Investors should consider the implications of such exposure.

Risk of Forks and Protocol Changes

The underlying protocol governing cryptoassets, including Bitcoin, may be altered through network upgrades or contentious forks. Such changes can result in the creation of new digital assets or disruption to existing holdings. The Company may face operational challenges in managing forks or adapting to protocol changes. There is also the risk of loss or confusion regarding asset ownership.

Cybersecurity Threats

The Company’s cryptoassets are attractive targets for cybercriminals seeking to exploit vulnerabilities. Cybersecurity threats include phishing, malware, ransomware, and denial-of-service attacks. A successful attack could compromise the company’s systems or result in unauthorised transfers. Ongoing investment in cybersecurity measures is necessary to mitigate these risks.

Loss or Destruction of Private Keys

Access to cryptoassets, including Bitcoin, are controlled by private cryptographic keys, the
