Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company's current beliefs, expectations and assumptions regarding the future of its business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of the Company's control. The information in this announcement about the Company's anticipated redemption and mandatory exchange of its 2026 Notes are forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause the Company's actual results and financial condition to differ materially from those indicated in the forward-looking statements include market conditions; the Company's ability to implement the Restructuring Plan on the expected timeline or at all; the ability to retain the Company's listing on Nasdaq; operational, financial, regulatory, tax and legal risks; assumptions underlying revenue, EBITDA and valuation estimates; and the principal risks and uncertainties described in the risk factors set forth in the Company's Annual Report and Financial Statements and Form 20-F for the year ended 31 December 2024.
