Bitcoin Mining Activity for the Month of June 2026 and Reminder of the Strategic Choices

Bitcoin Mining Activity for the Month of June 2026 and Reminder of the Strategic Choices to Prioritize Bitcoin Mining and Depreciate the Assets of the CREATE Activity, with the Objectives of Operational Balance and the Addition of Servers Dedicated to Artificial Intelligence

• The annualized return for June 2026 is close to breakeven, at -2%, and was impacted by Bitcoin's decline towards US$60,000
• CBI recalls its decision to prioritize Bitcoin mining and to depreciate the assets of the CREATE activity which has been paused
• These strategic decisions improve the Company's cash position and do not result in any dilution of the shareholder base
• The objectives are to achieve operational balance and to expand the server park by adding machines dedicated to artificial intelligence

Paris, France, July 24, 2026, at 8:00 a.m. CET (CBI, Euronext Growth Paris: FR0014007LWO – ALCBI; OTCQB: CBIPF) – CRYPTO BLOCKCHAIN INDUSTRIES ("CBI") announces that, for the month of June 2026, the performance of mining servers measured in Bitcoins is stable compared to May 2026. Measured in US dollars, it is close to equilibrium at -2% as it has been negatively impacted by Bitcoin's decline towards US$60,000. CBI further recalls the strategic decision announced in March 2026 to prioritize Bitcoin mining activities and to pause the development of the CREATE business, as well as to write down the assets associated with this activity in the accounts as of March 31, 2026. These impairments have no impact on CBI's cash position. These strategic decisions actually improve the Company's liquidity and do not result in any dilution of the shareholding. The objectives are to achieve operational balance and to expand the server park by adding machines dedicated to artificial intelligence.

As of June 2026, the entire park, more than 700 operational servers, has been operating without major disruption, allowing for regular Bitcoin production in line with expectations.

Measured in Bitcoins, the yield of mining servers for the month of June 2026 is stable compared to May 2026.

Measured in US dollars, the yield is close to equilibrium at -2% as it has been negatively impacted by Bitcoin's decline towards US$60,000. This return is insufficient and the objective remains to return, thanks to the rise of Bitcoin, to around 20% per year.

This return is calculated only on a cash basis, by relating the gross margin generated by the activity (Bitcoins received during the month minus the monthly electricity bill) to the amount invested in the servers, all brought back on an annual basis. Accounting depreciations, as well as the resale price of the servers, are not taken into account in these estimates.

This profitability is likely to increase or decrease depending on various criteria, including the purchase price of the servers, the price of Bitcoin which directly influences the value of the commissions received, the cost of electricity, as well as the difficulty rate of the Bitcoin network which measures the complexity of mining a block. These annualized return figures are estimated for a given month, based on preliminary electricity billing by Blockware Solutions. If this invoice is subsequently adjusted by Blockware Solutions to take into account the actual consumption, the estimated yield is then adjusted retroactively.

Composition of the portfolio of crypto-assets and similar assets, including mining servers

CBI's portfolio of crypto-assets and related assets (see Table) recorded a stable performance compared to the previous month, despite a Bitcoin price that fell to around US$60,000.

The portfolio remains of a significant size and consists mainly of Bitcoins received as part of mining operations, the value of which was impacted during the month of June 2026, in addition to assets directly related to the production infrastructure, in particular mining servers. It also includes fiat currency reserves that the group plans to deploy in accordance with its capital allocation policy. Tokens created by CBI itself are not subject to an accounting valuation.

It should be remembered that some listed crypto-assets are held for periods of more than twelve months, as part of a long-term investment strategy.

Reminder of the March 2026 announcement on the one hand to prioritize Bitcoin mining activities and on the other hand to pause the CREATE development activity / Associated accounting impairments in the accounts as of March 31, 2026

March 2026 Strategic Decisions

CBI has confirmed its decision to prioritize Bitcoin mining (ACQUIRE/EARN). CBI also announced the pause in the development of the CREATE activities (emoji™, AlphaVerse/Football at AlphaVerse) and the search for partners, with an accounting impairment of the assets attached to this activity.

Mr. Christophe Chaix, Director of CBI, has announced his decision to resign from his position.

Impairments as at March 31, 2026

The consolidated financial statements as of March 31, 2026 will be published on July 31, 2026 when available, after approval by the Board of Directors and conclusion of audit procedures.

As of September 30, 2025, the accounting consequences of these decisions had been anticipated with provisions of €(6,989)K. As of March 31, 2026, in view of the above-mentioned decision, the assets related to the CREATE activities will be written down in full with an additional provision of around €(11,000)K.

In fiscal year 2026, these provisions mainly cover an impairment of AlphaVerse/Unity assets for €(9,400) K and deferred charges for €(2,200)K, a provision for trade receivables for €(3,100)K, and a provision for foreign exchange losses on the crypto portfolio of €(2,800)K.

The assets of the CREATE activity remain the full property of CBI and can still be exploited. The provisions will be kept and could be taken over in the future in the event of a successful launch of these operations in association with partners.

These impairments have no impact on CBI's cash position / Improvement of the Company's liquidity / Operating breakeven objective

These strategic decisions improve the Company's liquidity. Thus, CBI has already parted ways with the employees and consultants of the CREATE activity, and Frédéric Chesnais' remuneration will now be linked to CBI's performance.

For the 2026-2027 financial year, operating needs are covered by existing cash resources. The company has a single $1 million in financial debt to third parties outside of Ker Ventures, collateralized by Bitcoins.

The objectives are to achieve operational balance and to expand the server park by adding machines dedicated to artificial intelligence.

No dilution of the shareholding

These decisions also have no impact on the dilution of the shareholding, as the only ongoing program remains that of the BSA A exercisable at €0.40 per share and the BSA B exercisable at €0.60 per share, and which overall represent a dilution of around 4.1% of the existing shareholder base.

Warnings

The implementation of CBI projects, as well as their operational budget and financing plan, remain fundamentally subject to significant uncertainties. Failure to meet the underlying assumptions could have a material and negative impact on the value of CBI's assets and liabilities. In addition, investing in crypto-assets carries risks related in particular to their intrinsic volatility, which can affect the financial performance of the CBI. CBI reminds investors that the past performance of crypto-assets is not a guarantee of their future performance. A detailed description of the risks associated with an investment in CBI's securities is available in the Company's financial reports on its website www.cbicorp.io.
