This presentation does not purport to be all-inclusive or to contain all of the information you may desire. Certain information contained in this presentation relates to or is based on studies, publications, surveys and other data obtained from third-party sources and the company’s own internal estimates and research. While argenx believes these third-party studies, publications, surveys and other data to be reliable as of the date of this presentation, it has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party sources. In addition, no independent source has evaluated the reasonableness or accuracy of argenx’s internal estimates or research and no reliance should be made on any information or statements made in this presentation relating to or based on such internal estimates and research. The financial results presented in this presentation are preliminary, estimated, and unaudited. They are subject to the completion and finalization of argenx’s financial and accounting closing procedures. They reflect management’s estimates based solely upon information available to management as of the date of this presentation. Further information learned during that completion and finalization may alter the final results. In addition, the preliminary estimates should not be viewed as a substitute for full quarterly and annual financial statements prepared in accordance with IFRS. There is a possibility that argenx’s financial results for the quarter ended December 31, 2023, and full year financial results for 2023 could vary materially from these preliminary estimates. In addition to the completion of the financial closing procedures, factors that could cause actual results to differ from those described above are set forth below. Accordingly, you should not place undue reliance upon this preliminary information. Additional information regarding the Company’s fourth quarter 2023 financial results and full year financial results for 2023 will be available in the Company’s annual report and Form 20-F, which will be filed with the Netherlands Authority for the Financial Markets and U.S. Securities and Exchange Commission (the “SEC”), respectively.
