Disclamers

The completion of CBI's projects, as well as their operating budget and financing plan, remain fundamentally subject to major uncertainties. Failure to meet the underlying assumptions could have a significant 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, which may affect CBI's financial performance. CBI reminds investors that the past performance of crypto-assets does not guarantee their future performance. A detailed description of the risks associated with investing in CBI securities is available in the company's financial reports on its website.
