This Amendment No. 3 (this Amendment) amends and supplements the Schedule 13D originally filed with the Securities and Exchange Commission (the SEC) on February 12, 2024 (as amended, the Schedule 13D), by the Reporting Persons with respect to the common stock, par value $0.01 per share (the Common Stock), of GrafTech International Ltd., a Delaware corporation (the Issuer).

Unless otherwise indicated, all share figures in this Amendment reflect the Reverse Stock Split.
