Except as specifically provided herein, this Amendment No. 1 does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used herein shall have the meanings ascribed to them in the Schedule 13D. | ||

Consequently, on July 6, 2024, SC received an additional 261,865 voting rights and on October 22, 2024, SC received an additional 584,000 voting rights.SC may, from time to time, acquire additional Ordinary Shares and/or ADSs or sell all or a portion of the Ordinary Shares and/or ADSs held by SC in the open market or in privately negotiated transactions, or may distribute the Ordinary Shares and/or ADSs held by SC to its unitholders. Any actions SC might undertake will be dependent upon its review of numerous factors, including, among other things, the market prices of the Ordinary Shares and ADSs, general market and economic conditions, ongoing evaluation of the Issuer's business, financial condition, operations and prospects, the relative attractiveness of alternative business and investment opportunities, investors' need for liquidity, and other future developments.Except as described in this Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although, the Reporting Persons, at any time and from time to time, may review, reconsider and change their position and/or change their purpose and/or develop such plans and may seek to influence management or the Board of Directors of the Issuer with respect to the business and affairs of the Issuer and may from time to time consider pursuing or proposing such matters with advisors, the Issuer or other persons. | ||
