Yellow Network Strategic Partnership Update

Treasury Update

Gibraltar, 1 December 2025 – Coinsilium Group Limited (AQSE: COIN | OTCQB: CINGF), the Aquis-quoted digital asset investor and venture builder, is pleased to provide the following strategic partnership update in preparation for the forthcoming YELLOW Network (“Yellow”) token launch.

Coinsilium is a long-standing backer of Yellow Network, alongside several other high-profile ecosystem and digital asset industry partners and has built a strong and structured working relationship with the Yellow team over the course of its ongoing involvement with the project. With the Yellow Network token launch now approaching, and in light of heightened regulatory scrutiny across the digital asset sector, the Company is taking this opportunity to provide this update, to ensure that Coinsilium shareholders, Yellow Network contributors, project partners and the wider market have a clear understanding of the regulatory considerations that inform the Company’s position in relation to the YELLOW token and interpret the Company’s communications accordingly. As a publicly quoted company, Coinsilium is committed to ensuring that its disclosures remain aligned with the most current applicable regulatory frameworks.

Within the context of applicable regulation, on the basis of information made available to the Company, the YELLOW token will be classified as a Utility Token. Utility tokens are designed to enable specific functions within a given network or protocol, and the token to be issued by Yellow Network has been structured solely to provide such functional utility. In major jurisdictions, including the US, UK and EU, regulatory guidance distinguishes utility tokens—whose purpose is to enable access to and participation in specific network functions—from tokens that operate as investment instruments. Within this regulatory treatment, utility tokens are generally characterised as follows:

• they provide access to defined network functions, services or participation within a protocol;
   
• they are not structured or intended to confer rights of ownership, dividends, revenue share, profit-participation or capital appreciation;
   
• they do not give rise to any expectation of financial return or upside, with any value relating solely to their operational use within the relevant network.

Based on the information made available to the Company, the YELLOW Network token has been designed to serve a strictly functional role within the Yellow Network protocol, aligning it with the regulatory treatment applicable to utility tokens in the relevant jurisdictions. As understood by the Company, its utilities include collateralising state channels for broker security, paying automated settlement fees, and providing network access for developers.  It is also the Company’s understanding that the finalised YELLOW tokenomics are confined to these utility functions and do not incorporate any buy-back provisions, revenue-sharing arrangements, or profit-distribution mechanisms.

This regulatory position update, together with the description provided regarding the YELLOW token’s utility-only structure, supersedes any previous public statements, communications, reports, and documentation concerning the YELLOW token’s economic design and intended function. It is being issued to set out the Company’s position and its understanding of the regulatory considerations relevant to the YELLOW token, and to ensure that the Company’s own communications regarding the forthcoming YELLOW token launch and subsequent developments can be interpreted on a consistent and accurate basis.

YELLOW Network Project Overview

The YELLOW Network is a chain-agnostic Layer-3 infrastructure designed to address key inefficiencies in digital asset markets, including:

• fragmentation of liquidity across multiple blockchains and trading venues;
   
• the need for high-throughput, low-latency cross-chain messaging, routing and settlement;
   
• the reduction of counterparty and bridge-risk through a non-custodial, peer-to-peer clearing architecture.

The Layer-3 framework is expected to support a growing number of applications and services developed on top of the network, reflecting the project’s ambition to enable scalable, high-performance decentralised trading infrastructure.

Strategic Partnership Update

Coinsilium has been a backer of the Yellow Network project since entering into a SAFT (Simple Agreement for Future Tokens) as announced on 21 April 2022, under which the Company is entitled to receive USD 200,000 in value of YELLOW tokens, subject to vesting in accordance with the terms of the agreement. Since entering into the SAFT, the Company and the Yellow Network team have continued to work closely together, developing a strong and constructive working relationship. Throughout this period, the Company has gained a clear appreciation of Yellow Network’s capabilities, execution to date, and the ambition underpinning its development.

As the YELLOW token launch event approaches, this currently remains the primary focus for both parties. At the same time, and looking beyond the launch, initial discussions have begun around potential post-launch opportunities for further ongoing collaboration, particularly in areas where Coinsilium may be able to support the continued evolution and growth of the YELLOW Network ecosystem and contribute to priorities such as the decentralisation of network governance.

Within this emerging framework, the potential scope of post-launch opportunities may also include:

• supporting projects emerging within the YELLOW Network ecosystem;
   
• evaluating technical and commercial initiatives aligned with Yellow Network’s development; and
   
• identifying areas where Coinsilium’s venture-building, advisory and sector expertise may contribute to the growth of the YELLOW Network ecosystem.

The Company looks forward to providing further updates as YELLOW Network progresses toward its token launch and, as current workstreams advance, to sharing more detail on the additional collaborative opportunities and ecosystem-development initiatives it is actively working on, once in a position to do so.

Coinsilium also confirms that both the Company and Yellow Network will participate in Consensus Hong Kong 2026, taking place from 10–12 February 2026 at the Hong Kong Convention & Exhibition Centre. Senior representatives from both organisations, including Coinsilium CEO Eddy Travia, Coinsilium Strategic Advisor James Van Straten and Yellow Network co-founder Alexis Sirkia, are scheduled to speak at the event.

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. The Company is aware of the particular risks Bitcoin presents to its financial position, which include but are not limited to:

(i) Volatility: Bitcoin is subject to significant price fluctuations, and its value can decline sharply over short periods, just as it can appreciate. Investors should be aware of the potential for substantial losses.

(ii) Lack of Regulation: The Bitcoin market operates with minimal regulatory supervision in many jurisdictions. This increases the risk of financial loss arising from events such as cyber breaches, illicit activity, or the failure of counterparties.

(iii) Liquidity Risk: The Company’s ability to liquidate its Bitcoin holdings is not guaranteed and may be subject to constraints. Factors that could affect this include market conditions at the time of sale, availability of counterparties, and unforeseen disruptions such as liquidity shortfalls, system outages, or cybersecurity incidents.

(iv) Reputational and Security Concerns: The cryptoasset sector continues to face reputational challenges, including associations with fraud, money laundering, and cyber-related threats. These concerns are not unfounded, particularly in certain areas of the market. However, based on over a decade of operational experience in the virtual assets industry, the Company has developed a deep understanding of the real-world risks and has established practices to navigate them responsibly—particularly in relation to Bitcoin.

Prospective investors are strongly encouraged to conduct their own research and carefully consider these risks before making any investment decision.

Nothing herein amounts to a recommendation to invest in the Company or to investment, taxation or legal advice. For further detail, please refer to the Company’s Bitcoin Treasury Policy and Strategic Plan.
