GrafTech Announces 1-for-10 Reverse Stock Split of Common Stock

Common Stock Expected to Begin Trading on Reverse Split-Adjusted Basis on August 29, 2025

BROOKLYN HEIGHTS, Ohio--(BUSINESS WIRE)-- GrafTech International Ltd. (NYSE: EAF) (“GrafTech,” the “Company,” “we,” or “our”) today announced that its Board of Directors has approved a 1-for-10 reverse stock split (the “Reverse Stock Split”) of GrafTech’s common stock, par value $0.01 per share (the “Common Stock”). The Reverse Stock Split was approved by GrafTech’s stockholders at a Special Meeting of Stockholders held virtually on August 14, 2025. The Reverse Stock Split will become effective at 12:01 a.m. Eastern Time on August 29, 2025, and the Common Stock will open for trading on The New York Stock Exchange (the “NYSE”) on a reverse split-adjusted basis on August 29, 2025 under the existing trading symbol “EAF.”

The new CUSIP number for the Common Stock following the Reverse Stock Split will be 384313 607.

At the effective time of the Reverse Stock Split, every ten (10) shares of the Common Stock either issued and outstanding or held as treasury stock will be automatically reclassified into one (1) share of the Common Stock. The total number of shares of the Common Stock authorized for issuance will be reduced by a corresponding proportion from 3,000,000,000 shares to 300,000,000 shares. The total number of shares of GrafTech’s preferred stock, par value $0.01 per share (the “Preferred Stock”), authorized for issuance will be reduced by a corresponding proportion from 300,000,000 shares to 30,000,000 shares. The par value of the Common Stock and the Preferred Stock will remain unchanged at $0.01 per share.

As a result of the Reverse Stock Split, proportionate adjustments will be made to the number of shares of the Common Stock underlying GrafTech’s outstanding equity awards and the number of shares issuable under GrafTech’s equity incentive plan, as well as the exercise, grant and acquisition prices of such equity awards, as applicable.

No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders of record who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will automatically be entitled to receive an additional fraction of a share of Common Stock to round up to the next whole share. With respect to outstanding Common Stock held in “street name” through a bank, broker or other nominee, fractional shares will be rounded up at the participant level. Cash will not be paid for fractional shares.

Computershare Trust Company, N.A. is acting as transfer and exchange agent for the Reverse Stock Split. Record stockholders who hold shares of the Common Stock electronically in book-entry form are not required to take any action to receive post-reverse split shares. Banks, brokers or other nominees will be instructed to effect the Reverse Stock Split for their customers holding shares of the Common Stock in “street name,” subject to such bank, broker or other nominee’s particular processes. Record stockholders holding shares of the Common Stock in certificated form will be sent a transmittal letter by the transfer and exchange agent after the effective time of the Reverse Stock Split. The letter of transmittal will contain instructions on how a stockholder should surrender his, her or its certificate(s) representing shares of the Common Stock to the transfer and exchange agent.

Additional information about the Reverse Stock Split can be found in GrafTech’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) on July 11, 2025, which is available free of charge at the SEC’s website, www.sec.gov, and on GrafTech’s website at ir.graftech.com/investors.
