Warnings

The implementation of CBI projects, as well as their operational budget and financing plan, remain fundamentally subject to major uncertainties. Failure to achieve the underlying assumptions could 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 may affect CBI's financial performance. 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.
