("Coinsilium" or the "Company")

Predictive Labs Achieves Further Development Milestones; Coinsilium Increases Investment with Further Subscription

Gibraltar, 24 August 2026 – Coinsilium Group Limited (AQSE: COIN | OTCQB: CINGF), the Aquis-quoted digital asset venture builder, is pleased to provide an update on the continued development of Predictive Labs Pte. Ltd. ("Predictive Labs"), a Coinsilium-backed venture and strategic advisory client.

Following the achievement of further agreed development milestones relating to Nijinn, Predictive Labs' prediction markets analytics platform, Coinsilium, through its wholly owned Gibraltar-based subsidiary Seedcoin Limited ("Seedcoin"), has elected to exercise its right to subscribe to a further US$100,000 of preference shares under the existing investment agreement.

Highlights

• Predictive Labs has completed Milestone 4 and the Stage 2 deliverable under the agreed development schedule, with Nijinn now operating end to end as an integrated Alpha on deployed infrastructure.
• Development progress includes delivery of the Alpha user interface and Indexing Engine, together with the implementation of Nijinn's core user experience and significant progress across its Pro intelligence functionality.
• Nijinn's Pro functionality demonstrated to date includes Cross-Venue Arbitrage, Informed Directional Trading, Market Making and Real-World Hedging.
• Following achievement of the agreed milestones, Coinsilium has elected to subscribe for a further US$100,000 of preference shares, increasing its total investment to US$450,000 and its holding to approximately 14.91% of Predictive Labs' issued share capital.
• Nijinn remains broadly on track with its previously announced rollout timetable, with the free to use version expected to launch following completion of the Pioneer Circle testing and the planned commercial launch of Nijinn Pro around Token2049 in Singapore in early October 2026.
• Recent developments across the prediction markets sector continue to demonstrate growing adoption, trading activity and investor interest, reinforcing the market opportunity for specialist analytics and intelligence platforms such as Nijinn.

Coinsilium Exercises Further Investment Rights

As announced on 14 July 2026, Coinsilium's investment in Predictive Labs stood at US$350,000, representing 7,630 preference shares, equivalent to approximately 11.99% of Predictive Labs' issued share capital. Following achievement of the further development milestones outlined above, Seedcoin has elected to exercise a further US$100,000 of this remaining subscription right. Upon completion, Coinsilium's total investment will increase to US$450,000, representing 9,810 preference shares, equivalent to approximately 14.91% of Predictive Labs' issued share capital.

Seedcoin will retain the right to subscribe for a further US$50,000 of preference shares under the initial US$500,000 investment stage. If exercised in full, Coinsilium's total investment under this initial stage would increase to US$500,000, representing 10,900 preference shares and approximately 16.29% of Predictive Labs' issued share capital.

As previously announced, the investment agreement also provides the Company with additional staged subscription rights beyond the initial investment stage which, if ultimately exercised in full, would increase its interest in Predictive Labs to approximately 29.85% of the issued share capital. Shareholders are referred to the Company's announcement of 16 March 2026 for further details of the investment structure and option arrangements.

The preference shares are convertible into ordinary shares at the election of Coinsilium and therefore represent an interest in the total equity of Predictive Labs whilst retaining certain additional rights over and above ordinary shares prior to conversion.

Development Milestones Achieved

As announced on 14 July 2026, Predictive Labs unveiled Nijinn, its first commercial product and the first major commercial development milestone for the business since Coinsilium's initial investment.

Nijinn is a dedicated analytics and discovery platform designed to aggregate and analyse information across multiple prediction-market venues, helping professional market participants identify opportunities, benchmark performance and interpret market signals.

Importantly, Nijinn is not itself a prediction market or trading venue. It has been designed as an analytics-only platform and does not execute trades, custody assets or hold positions. Its role is to provide an independent data and intelligence layer serving traders, funds, developers and AI agents participating across the prediction markets ecosystem.

Since Coinsilium's previous update, Predictive Labs has continued to progress the development of Nijinn and has now completed Milestone 4 and delivered Stage 2 under the agreed development schedule.

Nijinn is now operating end to end as an integrated Alpha on deployed infrastructure. The Alpha user interface has been delivered and is running on top of the underlying data pipeline, while the Indexing Engine is now in place, organising normalised market data into the unified global index used by the Nijinn interface. The platform therefore operates across the full workflow, from data ingestion and indexing through to the user-facing screens.

Development progress also includes the implementation of Nijinn's core user experience, including market discovery, event and market analytics, watchlists and account functionality, designed to provide users with Nijinn analytics alongside supported prediction-market venues and direct access to the wider Nijinn platform.

Significant progress has also been achieved across Nijinn's Pro intelligence functionality, including Cross-Venue Arbitrage, Informed Directional Trading, Market Making and Real-World Hedging.

Predictive Labs has also developed the supporting administrative infrastructure required to operate the platform, including user and administrator management, accuracy monitoring, revenue and attribution functionality, entitlement management and administrative review of market data.

Completion of the integrated Alpha closes the Stage 2 deliverable under the agreed milestone schedule. Predictive Labs is now progressing towards user acceptance testing ("UAT") and the live minimum viable product ("MVP") stage.

Prediction Markets Sector Momentum

The continued development of Nijinn is taking place against a backdrop of growing adoption, trading activity and investment across the prediction markets sector.

Recent developments since Coinsilium's previous update provide further evidence of the increasing scale of the market. On 23 July 2026, Reuters reported that Kalshi recorded approximately US$27 billion in trading volume and attracted around 3 million users during the 2026 FIFA World Cup, approximately double the US$13 billion in volume and 1.5 million users the platform had anticipated.

https://www.reuters.com/sports/soccer/kalshi-hits-back-net-with-27-billion-fifa-world-cup-windfall-2026-07-23/

Investor interest has also continued to grow. On 4 August 2026, Reuters reported that Polymarket was in early discussions to raise approximately US$1 billion at a valuation exceeding US$20 billion, following its US$1 billion fundraising at a US$15 billion valuation in April.

The Board considers these developments further evidence of the growing scale and adoption of prediction markets and of the expanding opportunity for specialist analytics and intelligence platforms such as Nijinn. As trading activity expands across an increasing number of venues, the need to aggregate, analyse and interpret increasingly fragmented market data, liquidity and pricing information becomes correspondingly more relevant.

Nijinn Commercial Progress and Next Steps

Since Coinsilium's previous update, Predictive Labs has continued to progress Nijinn in line with the development and commercial rollout timetable announced on 14 July 2026.

WikiEXPO Hong Kong took place on 23–24 July 2026, where Predictive Labs Founder and Chief Executive Officer Johann Evrard joined Coinsilium Chief Executive Officer Eddy Travia for a panel discussion examining the development and broader adoption of prediction markets.

The prediction markets panel session is now available to watch online and begins at approximately 05:22:00:

Predictive Labs has confirmed that development remains broadly on track against its previously announced rollout timetable. The free version of Nijinn is expected to launch following completion of testing through the Pioneer Circle, with a broader public launch expected during September and the commercial launch of the premium Nijinn Pro tier planned around the Token2049 conference in Singapore in early October 2026.

These next stages will represent further important milestones in the development and commercial rollout of Nijinn as Predictive Labs progresses from early access towards broader public availability and commercialisation.

Eddy Travia, Chief Executive Officer of Coinsilium, commented:

"Predictive Labs continues to deliver against its development roadmap. The completion of Stage 2, with Nijinn now operating end to end as an integrated Alpha, represents another important step in the development of the platform.

The achievement of these latest milestones provides the basis for our decision to increase our investment in Predictive Labs to US$450,000. We are particularly encouraged by the pace of development and by the broader momentum we are seeing across the prediction markets sector.

Recent growth in trading volumes and user participation, together with the significant levels of investment and valuations being achieved by leading prediction market platforms, provide further evidence of a sector that is rapidly gaining scale and attracting increasing mainstream and institutional interest.

We believe this growth also strengthens the opportunity for the infrastructure and intelligence layer around prediction markets. As activity expands across multiple venues, so too does the need to aggregate and interpret increasingly fragmented data, liquidity and pricing information. This is precisely the market opportunity Nijinn has been designed to address.

With the platform progressing towards its next development and commercial milestones, we remain excited about the opportunity ahead and look forward to continuing to work closely with Johann and the Predictive Labs team."

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 loss or destruction of which results in permanent loss of the associated assets. Human error, hardware failure, or malicious activity could lead to key loss. The Company must implement robust key management protocols to reduce this risk. Even with precautions, there is no absolute safeguard.

Limited availability of Insurance

Insurance cover for digital assets such as Bitcoin may be limited or unavailable. Even where insurance is in place, it may not cover all potential losses or may be subject to exclusions and limitations. The Company may therefore be exposed to uninsured risks. Investors should be aware that insurance does not eliminate the possibility of loss.

Accounting and Valuation Uncertainty

The accounting treatment and valuation of cryptoassets, including Bitcoin, may be subject to differing interpretations and evolving standards. Changes in accounting policies or guidance could affect the Company’s financial statements. Valuation challenges may arise due to price volatility or lack of observable market data, particularly for early stage cryptoassets without an established track record or which are not widely held. This could impact reported results and investor understanding.

Risk of Regulatory Enforcement

Authorities may take enforcement action against companies involved in digital assets, including Bitcoin. Such actions could include fines, sanctions, or restrictions on operations. The Company may incur significant costs in responding to investigations or defending its position. Regulatory enforcement could have a material adverse effect on the business.

Cross-Border Risks

Cryptoasset transactions are global and may expose the company to cross-border legal, regulatory, or tax risks. Differences in jurisdictional approaches could result in conflicting obligations or increased compliance burdens. The Company may face challenges in navigating international regulatory frameworks. Cross-border risks may also affect the ability to transfer or realise assets.

Risk of Market Manipulation

Cryptoassets and the markets on which they are traded are susceptible to manipulation due to its relative lack of oversight and transparency. Market participants may engage in practices such as spoofing, wash trading, or pump-and-dump schemes. Such activities can distort prices and adversely affect the Company’s holdings. Regulatory intervention may not always prevent or remedy market abuse.

Lack of Recourse and Consumer Protections

Unlike traditional financial assets, cryptoasset holdings, including Bitcoin, may not benefit from statutory recourse or consumer protection schemes. In the event of loss, theft, or fraud, investors may have limited or no avenues for recovery. The Company’s exposure to Bitcoin is therefore inherently riskier than holding regulated financial instruments. Investors must consider the implications of this lack of protection.

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.
