4 Instead of Strategy and Real Solutions Management Offers Personal Attacks and No Accountability • Shareholders should not be fooled by GrafTech’s a ttempt to obfuscate the issues and distract with personal attacks. • Management’s investor presentation fails to address unprecedented value destruction. GrafTech’s market cap. w as $4.4 billion at the time of its IPO in April 2018. Today, it is $380 million. Incumbent nominee Anthony Taccone , has presided over $4 billion of shareholder value destruction during his tenure. • Instead of addressing the core issues affecting the business and loss of shareholder value , GrafTech has resorted to meritless attacks against a large shareholder with credible institutional investor experience. • We believe GrafTech’s board urgently needs a shareholder representative with skin in the game to help reverse the destruction of shareholder value and revive GrafTech .

5 GrafTech’s Board Continues to Mislead Shareholders About Client Outreach Efforts Management’s “campaign to restore customer relationships” continues to include costly litigation with clients over long - term agreements (LTAs) These LTAs have been universally deemed as bad for clients in the long - run, as described by one analyst: “…it’s kind of tails you win, heads the customer loses in the sense they pay higher pricing” – Michael Gambardella JP Morgan Securities, Earnings Call 11/2/2018 Management has refused to accept any accountability for their deployment, blaming their use instead on the previous controlling shareholder Sales in the Americas accounted for 49% of Total Revenue in 2023, which means that by having a ‘dozen meetings’ with customers representing 75% of sales in the Americas, management met with customers responsible for ONLY 37% of total revenue “ We are involved in certain arbitrations…with a few customers who, among other things, have failed to perform under their LTAs and in certain instances are seeking to modify or frustrate their contractual commitments to us. In particular, Aperam South America LTDA, Aperam Sourcing S.C.A., ArcelorMittal Sourcing S.C.A., and ArcelorMittal Brasil S.A. (collectively, the “Claimants”) initiated a single arbitration proceeding against two of the Company’s subsidiaries… We believe we have valid defenses to these claims. We intend to vigorously defend them and enforce our rights under the LTAs.” Sources: GrafTech Investor Presentation 4 - 15 - 2024 , GrafTech 2024 10 - K 1 2 1 1 2 2 Reality GrafTech Claims

6 The Board Was Never Open To Mr. Undavia’s Candidacy Debra Fine Nominating and Corporate Governance Committee Chair “We’re not looking for board members” (from less than 5 - minute call on Jan. 10, 2024 with Nilesh Undavia regarding his board candidacy) • The Board continues to purport its openness to shareholder views, while throwing its former controlling shareholder under the bus for the problems facing the Company today 1 • Committee Chair Fine spent less than five minutes with Mr. Undavia via phone on January 10, 2024, when he and his candidacy were promptly dismissed • Shareholders should not be surprised as we have seen the Board conduct two failed CEO searches over the past two years; we have no reason to believe that director evaluations are conducted with any more competence or diligence Reality GrafTech Claims 1 Regarding LTAs, Management recently stated that: “These contracts were structured by Brookfield, a private equity firm, when they owned GrafTech ... As our business continues to shift to a more spot - oriented commercial approach, we have embarked on a deliberate campaign to reinforce the importance of the partnership we have with our valued cu sto mers.” GrafTech Open Letter to Shareholders, 4 - 2 - 2024

7 Despite the Board’s Claims, Mr. Undavia Has Relevant Skills And Credentials • Institutional investor for over 30 years, the majority of which were spent analyzing global raw materials industries • Employed at Wellington Management Co, LLP in Boston for nearly 25 years, where he was a Partner and Senior Managing Director of the firm • Portfolio Manager of Undavia Family Investment Office, a position he has held since 2018 • Previously worked as an analyst in Credit Suisse First Boston from 1988 – 1990 • Deep experience in global macro - economic cycles, global steel industry, global energy and raw materials industries, corporate strategy, maximization of shareholder value, capital markets, and mergers and acquisitions • Bachelor of Arts from Columbia University • MBA from the Amos Tuck School of Business Administration, Dartmouth College Reality GrafTech Claims

8 Unlike The Board, Mr. Undavia Takes Accountability And Prompt Corrective Action • Mr. Undavia is not a professional activist, and has never before been forced by Board intransigence to run a proxy contest • The Company further refused to cooperate with Mr. Undavia to clarify its confusing questions • Mr. Undavia did his best to complete the Board’s ambiguously worded nominee questionnaire and when alerted that he had made some inadvertent errors, he promptly corrected them • Regarding Mr. Undavia’s omission of information regarding his estranged sister, he did not consider her to be a part of his "immediate family" as she neither resides with him nor has he had any relationship with her at any time during the past fiscal year. Again, when this omission was identified, Mr. Undavia promptly corrected his response Reality GrafTech Claims

9 It Is The Board – Not Nilesh Undavia – Who Is Not Forthcoming and Truthful With Shareholders • The Company has never provided an adequate explanation for the damaging shutdown at Monterrey nor held anyone accountable o In operation since 1959, the Monterrey plant has over 550 employees and represents approximately 60 thousand MT of annual production capacity, or 30% of total annual production capacity (excluding St. Marys ) o On September 15, 2022, Mexican regulators inspected GrafTech’s manufacturing facility located in Monterrey, Mexico and imposed a temporary suspension o The suspension was lifted on November 17, 2022 , upon agreement that GrafTech would submit an environmental impact study with respect to the facility’s operations o While operations were only suspended for two months, the Company estimates that the suspension of operations had a negative impact of approximately $13 million on adjusted EBITDA in the third quarter of 2022 , primarily reflecting the foregone sales volume, and additional market share losses in 2023 • There was never a mention of the cause or reason for the failed oversight, and the Board seemingly did not hold Management accountable for the blunder, most notably the CEO at the time, Marcel Kessler, who had recently been appointed to the position on July 1, 2022 • CEO Kessler was never held accountable for the Monterrey shutdown and market share losses; shortly thereafter, he stepped down as CEO the following year citing “family reasons,” but was allowed to remain as a paid member of the Board Marcel Kessler Former CEO and Current Director Monterrey, Mexico Plant 1. GrafTech 10 - Q filed 11 - 4 - 2022

10 Management Must Do More Than Provide Cost - Cutting Transparency To Change Market Sentiment on the Stock • GrafTech is cherry - picking analyst commentary; it fails to disclose that J.P. Morgan as well as all other analysts who cover GrafTech have a HOLD/NEUTRAL rating on the stock, according to FactSet • Clearly, neither Wall Street analysts nor investors trust the management and the Board or have faith in the current strategy to revive GrafTech – if they did, why wouldn’t they have a more favorable rating • In comparison, according to FactSet, a majority of the analysts have BUY ratings for HEG Limited and Graphite India – two pure competitors of GrafTech • We believe, the key factor driving GrafTech’s unfavorable analyst ratings is not an industry downturn but the failure of management and the Board to develop and execute a credible strategy Reality GrafTech Claims

11 Changes in Director Stock Ownership Policy Insulates Board From Its Poor Performance “The Non - Employee Director Stock Ownership Policy was reviewed and revised by the Board in December 2022. Under the revised policy, effective December 1, 2022, independent directors are required, within five years of the later of December 1, 2022 and joining the Board, to acquire shares or share equivalents of the Company having an aggregate value equal to at least $600,000 (the “Stock Threshold”) … – 2024 GrafTech Proxy • As disclosed in the 2023 proxy statement, the Board amended its Stock Ownership Policy to account for the shareholder value destruction it caused • As NONE of the current board members were able to comply with the $600,000 threshold, the Board gave itself an extension until December 2027 for directors to comply • Instead of enforcing the policy and allowing directors to show faith in their own leadership by acquiring shares, the Board chose to allow its members to further enrich themselves through grants of cash and stock at historically low prices for an additional three years • In other words, the Board mitigated its equity risk exposure to its own poor performance at the expense of shareholders • This cannot be considered real skin in the game Reality GrafTech Claims

12 The Board Has Lost All Credibility With Investors • Since the Board began proclaiming that it has the right strategy and leadership, the stock has continued to underperform • No director has bought a single share in 2024 1 , which would show evidence they believe in GrafTech or its potential • According to FactSet, no Wall Street analyst has raised their rating to a “ BUY ” in response to management’s claims of having the right strategy and leadership 1 As of April 19, 2024
