CRYPTO BLOCKCHAIN INDUSTRIES : As of June 30, 2025, the return on investment from CBI's mining activities is estimated to exceed 25% over 3 years

• CBI purchases fleet of next-generation Bitmain ASIC miners operated by Blockware under a 10-year strategic partnership
• Since May 2025, each ASIC miner processes transactions and generates Bitcoin rewards paid daily to CBI
• As of June 30, 2025, based on an extrapolation over 3 years of the results achieved, the return on investment from mining operations is estimated at over 25%

Paris, France – July 3, 2025 at 8:00 AM CET – CRYPTO BLOCKCHAIN INDUSTRIES (CBI, Euronext Growth Paris: FR0014007LW0 - ALCBI) announces the first results of its mining operations launched in May 2025 as part of its strategic partnership with Blockware, a major player in the sector. As of June 30, 2025, performance analysis suggests a return on investment exceeding 25% over a three-year period.

CBI's BTC mining fleet consists of latest generation Bitmain ASIC models. The initial investment includes the price of the ASIC miner, security deposit for electricity, setup fees, and hosting costs. The total amount invested is slightly over USD 5,000 per mining unit, including security deposits. These servers are hosted and operated by Blockware in specialized data centers in the United States.

CBI's revenues come from Bitcoin mining rewards, the recovery of security deposits at the end of the term, and the residual resale value of the ASIC mining equipment, for which Blockware guarantees CBI a minimum price. Blockware ensures that up to 3 years, through their extensive network and ASIC marketplace they will secure a resale value of at least 25%, although CBI is under no obligation to sell them. The main operating expenses are electricity consumption and ongoing mining equipment maintenance.

Based on the performance observed as of June 30, 2025, and extrapolated over a 3-year period, the return on investment rate stands at over 25% for the period considered.

In practical terms, CBI invests in ASIC mining equipment, operates the fleet for three years, and then resells the equipment through Blockware. CBI covers operational expenses such as electricity and maintenance costs throughout the period. In return, it receives rewards daily in Bitcoins.

This profitability is subject to increase or decrease depending mainly on:

• the price of Bitcoin, which directly influences the value of the commissions received;
• the cost of electricity, which impacts operating expenses;
• the Bitcoin network difficulty rate. The difficulty rate measures how complex it is to mine a Bitcoin block and thus the level of commissions. Indeed, the higher it is, the more computing power is required and the fewer transactions are processed. An increase in the difficulty rate will reduce future returns.

The mining activity is part of CBI's ACE strategy: Acquire, Create, Earn. It aims to combine investment, technological innovation, and revenue generation in the blockchain ecosystem. CBI will continue to regularly publish information on the performance and outlook of this strategically important activity.

The realization of CBI's projects, as well as their operating budget and financing plan, remain fundamentally subject to major uncertainties, and the failure to meet the underlying assumptions could have a significant and adverse impact on the value of CBI's assets and liabilities.

Furthermore, investing in crypto-assets carries risks due to their inherent volatility, which could affect CBI's financial performance. CBI considers it important to remind readers that past performance of crypto-assets is not indicative of future results.
