September 2025

• In September 2025, mining activities generated a return on investment of over

Paris, France - October 2, 2025, at 8:00 a.m. CET (CBI - Euronext Growth Paris: FR0014007LW0 -

ALCBI; OTCQB: CBIPF) - CRYPTO BLOCKCHAIN INDUSTRIES ("CBI") announces annualized

returns on investment of over 30% for September 2025. These results confirm the returns seen

since the program's launch in June 2025, which also stand at over 30% on an annualized basis.

These results confirm the strength of the partnership with Blockware Solutions and reflect the

consistent performance and operational efficiency of the operations put in place.

Blockware Solutions is a recognized player in the blockchain infrastructure and cryptocurrency mining

sector. The company stands out for its ability to operate large-scale facilities, provide cutting-edge hosting

services, and develop innovative technology solutions, making it a natural partner for CBI.

In September 2025, CBI's mining activities generated an estimated return on investment of more than

30% on an annualized basis. This result confirms the strength of the partnership with Blockware

Solutions, which optimizes infrastructure performance and ensures efficient operations in a market that

remains highly volatile.

Since the program's launch, the cumulative return has also exceeded more than 30% on an annualized

basis, demonstrating the relevance of the business model and the operational efficiency of the operations

implemented by CBI.

This profitability is likely to fluctuate up or down depending on factors such as the price of Bitcoin, which

directly influences the value of commissions received, the cost of electricity, and the difficulty rate of the

Bitcoin network, which measures the complexity of mining a Bitcoin block and therefore the level of

commissions earned by CBI.

This mechanism is part of CBI's ACE (Acquire, Create, Earn) strategy, strengthening its ability to seize

international growth opportunities and helping to position CBI as a key player in the blockchain

ecosystem, while maximizing its exposure to the US market.

1Composition of the portfolio of crypto-assets and similar assets, including mining servers

CBI's crypto-asset portfolio continues to grow and is now estimated to be worth over US$10 million,

excluding the valuation of tokens created by CBI. This development reflects a strategy of continuous

accumulation, which strengthens the company's position in the digital asset market.

The portfolio includes fiat cash holdings that are being allocated to the acquisition of Bitcoins. These cash

holdings are valued at their nominal value.

As of September 2025, CBI's portfolio remains significant and includes the purchase of 180 additional

S21 Hydro servers for US$1.6 million, financed by the CBI block sale program. The value of the servers

is included in the "Blockware Servers" line.

The portfolio also includes investments in CEA Industries, the proceeds of which will be reinvested in

Bitcoin. The value of BNC shares is included in this portfolio under the line item "BNB CEA Industries"

.

2Disclaimers

The completion of CBI's projects, as well as their operating budget and financing plan, remain fundamentally subject to

major uncertainties, and failure to achieve the underlying assumptions may have a material and adverse impact on the

value of CBI's assets and liabilities. In addition, investing in crypto-assets involves risks related in particular to their intrinsic

volatility that could have an impact on CBI's financial performance. CBI considers it useful to remember that the past

performance of crypto-assets is not a guarantee of future performance. A detailed description of the risks associated with

an investment in CBI securities can be found in the Company's financial reports available on CBI's website.
