Although we believe that we have a reasonable basis for each forward - looking statement contained in this presentation, we caution you that forward - looking statements are not guarantees of future performance and that our actual results of operation, financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward - looking statements contained in this presentation as a result of, among other factors, the factors referenced in the “Risk Factors” section of the prospectus contained in the registration statement on Form F - 1 (File No . 333 - 259012 ) initially filed with the Securities and Exchange Commission (the “SEC”) on August 23 , 2021 as amended thereafter, for our proposed initial public offering (the "Registration Statement") .

Any forward - looking statement that we make in this presentation speaks only as of the date of such statement, and we undertake no obligation to update or revise publicly any of the forward - looking statements after the date hereof to conform the statements to actual results or changed expectations except as required by applicable law . This investor presentation provides basic information about the company and the offering . Because it is only a summary, this document does not cover all the information that should be considered before investing .
