PRELIMINARY PROXY STATEMENT – SUBJECT TO COMPLETION

[●], 2024

Dear Stockholders:

We are pleased to invite you to the 2024 Annual Meeting of Stockholders (the “Annual Meeting”). The Annual Meeting will be held on Thursday, May 9, 2024, at 8:00 a.m. Eastern Time. The Board of Directors (the “Board”) of GrafTech International Ltd. (“GrafTech,” the “Company,” “we,” or “our”) has determined the Annual Meeting will be held in a virtual format via the Internet again this year.

Details about the business to be conducted at the Annual Meeting can be found in the accompanying Notice of Annual Meeting of Stockholders and proxy statement. Your vote is important – especially this year. As you may have seen, Nilesh Undavia, along with certain trusts and people affiliated with Mr. Undavia (collectively, the “Undavia Group”), have provided notice of their intent to nominate Mr. Undavia (an “Undavia Group Nominee”) for election as director at the Annual Meeting in opposition to the nominees recommended by the Board.

The Board does not endorse the Undavia Group Nominee, and unanimously recommends that you vote “FOR” the election of the two (2) nominees proposed by the Board (Debra Fine and Anthony R. Taccone) and “FOR” the other proposals recommended by the Board, using the WHITE proxy card. You may receive solicitation materials from the Undavia Group, including proxy statements and [•] proxy cards. GrafTech is not responsible for the accuracy or completeness of any information provided by or relating to the Undavia Group or its nominee contained in solicitation materials filed or disseminated by or on behalf of the Undavia Group or any other statements the Undavia Group may make.

The Board strongly urges you to discard and NOT to vote using any [•] proxy card sent to you by the Undavia Group. If you have already submitted a [•] proxy card, you can revoke such proxy and vote for the Board’s nominees and on the other matters to be voted on at the Annual Meeting by marking, signing and dating the enclosed WHITE proxy card and returning it in the enclosed postage-paid envelope or by voting via the Internet or telephone by following the instructions on your WHITE proxy card, or WHITE voting instruction form. Only your latest validly executed proxy will count, and any proxy may be revoked at any time prior to its exercise at the Annual Meeting as described in the accompanying proxy statement.

PLEASE NOTE THAT THIS YEAR, YOUR WHITE PROXY CARD LOOKS DIFFERENT. RECENTLY ADOPTED PROXY RULES REQUIRE THE COMPANY’S WHITE PROXY CARD TO LIST THE UNDAVIA GROUP NOMINEE IN ADDITION TO THE BOARD’S NOMINEES. PLEASE MARK YOUR WHITE PROXY CARD CAREFULLY AND VOTE “FOR” ONLY THE TWO (2) NOMINEES AND PROPOSALS RECOMMENDED BY THE BOARD.

Regardless of whether you plan to attend the virtual Annual Meeting, we urge you to vote your shares as soon as possible. Additional information about voting your shares is included in the proxy statement.

##### Table of Contents

The Board appreciates and encourages stockholder participation in GrafTech’s affairs. We are confident that our slate of Board candidates has the right mix of professional achievements, skills, experiences and reputations that qualify the Company’s candidates to serve as stockholder representatives overseeing the management of the Company. We are committed to engaging with our stockholders and continuing to respond to stockholder concerns about the Company, and we believe we are in the best position to oversee the execution of our long-term strategic plan to grow and realize stockholder value. The Board unanimously recommends that you vote “FOR” the election of Ms. Fine and Mr. Taccone.

On behalf of the Board of Directors, thank you for your continued interest and support.

Sincerely,

Henry R. Keizer |  | Timothy K. Flanagan
Director and Chairman of the Board |  | Interim Chief Executive Officer and President

2023 Business Summary

Financial and Operating Performance

2023 was a challenging year for our business, marked by soft industry demand, the residual impact of the temporary suspension of our operations in Monterrey, Mexico that occurred in late 2022, and significantly higher costs. As a result, net sales decreased $660.8 million, or 52%, from $1,281.3 million in 2022 to $620.5 million in 2023, primarily reflecting lower sales volume. A shift in the mix of our business from volume derived from our take-or-pay agreements that had initial terms of three-to-five years (“LTA”) to volume derived from short-term agreements and spot sales (“non-LTA”) and lower weighted-average realized prices also contributed to the decline in net sales. Net loss for 2023 was $255.3 million compared to a net income of $383.0 million in 2022. Results for 2023 included a goodwill impairment charge of $171 million and a lower of cost or market inventory valuation adjustment of $12 million. Adjusted EBITDA1 for 2023 was $20.5 million compared to $536.5 million in the prior year, with the decline primarily due to lower sales volume, higher costs on a per metric ton (“MT”) basis, the shift in the mix of our business from LTA volume to non-LTA volume, lower weighted-average realized prices and the impact of a lower of cost or market inventory valuation adjustment recorded in 2023. Adjusted Net (Loss) Income1 decreased $480.5 million from Adjusted Net Income of $379.7 million in 2022 to Adjusted Net Loss of $100.8 million in 2023.

Against this backdrop, we are proactively managing our operating costs, capital expenditures and working capital levels. Specifically, our initiatives to manage working capital led to a more than $100 million reduction in inventory levels in 2023, resulting in positive free cash flow1 for the year. In 2024, we began executing a set of further initiatives designed to reduce our cost structure and optimize our manufacturing footprint while, at the same time, preserving our ability to deliver excellent customer service and to capitalize on long-term growth opportunities for our Company. These actions include: (1) indefinitely suspending production activities at our St. Marys, Pennsylvania facility, with the exception of graphite electrode and pin machining, as well as indefinitely idling certain assets within our remaining graphite electrode manufacturing footprint; (2) reducing the Company’s overhead structure and expenses; and (3) operating our remaining graphite electrode production facilities at reduced levels, as needed, to align production with our view on market demand.

##### Table of Contents

These initiatives, most notably the indefinite suspension of production at St. Marys and the reduction in Company overhead, are expected to result in annualized cost savings of approximately $25 million once fully implemented, excluding the impact of one-time costs. Of the anticipated cost savings, approximately $15 million are expected to be realized in cost of goods sold with the remainder in selling and administrative expenses. One-time costs are expected to be approximately $5 million, of which the majority are cash-related. In addition to being a key component of the incremental actions we are taking in response to weak market conditions, this will support our efforts to further reduce our inventory levels and manage capital expenditures in 2024. Specific to capital expenditures, for 2024 we anticipate spending to be in the range of $35 million to $40 million. This compares to capital expenditures of $54 million for the year ended December 31, 2023.

Key Operating Metrics

We use certain operating metrics to analyze the performance of our Company. The key operating metrics consist of sales volume, production volume, production capacity and capacity utilization. These metrics align with management’s assessment of our revenue performance and profit margin, and will help stakeholders understand the factors that drive our profitability. We reported sales volume of 91.6 thousand MT in 2023, a decrease of 39% compared to 2022. The amount of graphite electrodes we produced in 2023 decreased by 44%, from 157.1 thousand MT in 2022 to 88.1 thousand MT in 2023. Our capacity utilization, excluding our St. Marys graphite electrode manufacturing facility, decreased to 44% in 2023 compared to 78% in 2022, as we proactively reduced our graphite electrode production volume to align with our evolving demand outlook and to manage our working capital levels.

As of December 31, 2023, our stated production capacity was approximately 202 thousand MT(2)(3) through our primary manufacturing facilities in Calais, France; Pamplona, Spain; and Monterrey, Mexico. On February 14, 2024, the Company announced a cost rationalization and footprint optimization plan in response to persistent softness in the commercial environment. This includes an indefinite suspension of production activities at our St. Marys facility, with the exception of graphite electrode and pin machining. We are also indefinitely idling certain assets within our remaining graphite electrode manufacturing footprint. As a result of indefinitely idling certain assets, beginning in 2024, our stated production capacity will be approximately 178 thousand MT(2)(3), a reduction of 12% from our production capacity excluding St. Marys in 2023.

Maintaining a Disciplined Capital Allocation Strategy

We continue to have adequate liquidity in 2024 as we navigate the persistent softness in the commercial environment. As of December 31, 2023, we had liquidity of $289.3 million, consisting of $112.4 million of availability under our revolving credit facility and cash and cash equivalents of $176.9 million. As of December 31, 2023, we had gross debt of approximately $950.1 million.

Sustainability and Environmental, Social and Governance (“ESG”)

For more than 100 years, we have been manufacturing graphite electrode products that are essential to the production of electric arc furnace (“EAF”) steel. EAF steelmaking directly supports the circular economy as EAF steelmaking recycles scrap-based raw materials into new steel that is infinitely recyclable. EAF steelmaking is more environmentally friendly than blast furnace steelmaking, generating significantly less carbon dioxide emissions compared to a blast furnace facility according to the Steel Manufacturers Association.

Values and Culture

Our success is only possible with the hard work of our global team and their commitment to upholding our core values of Safety, Environment, and Quality, what we internally refer to as “SEQ.” These values focus our attention on a core mission for GrafTech: providing a safe work environment for all employees, environmental stewardship, and delivering superior product quality. We are committed to health and safety excellence and promoting the well-being of our people. We strive to improve our safety performance by focusing on programs and initiatives that hold all employees—from executives to the plant floor—accountable for keeping everyone safe, every day, across our global organization. |  |

Our Approach to Sustainability

Sustainability is fundamental to our business strategy and culture. Ultimate responsibility for sustainability is held by our ESG Steering Committee, which includes our Vice President of Investor Relations and Corporate Communications, Director of Health, Safety and Environmental Protection, Vice President, Operations and our senior leadership team, which is composed of the Interim Chief Executive Officer (“CEO”) and President; Interim Chief Financial Officer and Treasurer; Executive Vice President, Chief Operating Officer; Chief Legal Officer and Corporate Secretary; Vice President, Human Resources (“HR”); and Senior Vice President, Commercial and CTS. Our ESG Steering Committee is responsible for defining our ESG mission and developing, implementing, and overseeing the company-wide ESG strategy. Our ESG working group is composed of cross-functional subject matter experts and includes representatives from our environmental, health, and safety; legal; finance; communications; engineering; procurement; HR and commercial groups. The working group is responsible for developing and implementing programs and initiatives that support our ESG strategy, including: (1) providing support for ESG programs at our individual sites, (2) establishing, tracking, and reporting on key performance indicators relevant to our priority topics, (3) providing ESG-related disclosures to stakeholder groups, including publication of the annual sustainability report, and (4) identifying and prioritizing opportunities, emerging technologies, and strategies to help us improve our ESG performance. As part of our continuous improvement efforts, the capital planning process includes a review of the ESG impacts to ensure they are considered in the project approval process. A review of our ESG initiatives and metrics is shared in our monthly business review meetings. The senior leadership team also provides ESG strategy updates, including metrics, to the Board on a quarterly basis.

2023 ESG Update

In May 2023, GrafTech joined the United Nations Global Compact (“UNGC”), a voluntary leadership platform for the development, implementation, and disclosure of responsible business practices. The UNGC challenges companies to conduct business responsibly by aligning their strategies and operations with universal principles on human rights, labor, environment, and anti-corruption, and to take actions that advance societal goals. GrafTech is proud to join the UNGC, and we look forward to building upon our ESG strategies for the benefit of the environment and our stakeholders as we help shape a sustainable future.
Also, in May 2023, after completion of our 2023 EcoVadis assessment, we were awarded a Bronze sustainability rating by EcoVadis. EcoVadis assessed our sustainability performance in four key areas: environment, labor and human rights, ethics, and sustainable procurement. The EcoVadis sustainability assessment methodology is an evaluation of how well a company has integrated the principles of sustainability and corporate social responsibility into their business and management system. |  |

Corporate Governance

The business and affairs of GrafTech are managed under the direction of the Board. The primary function of the Board is oversight. The Board, in exercising its business judgment, acts as an advisor and counselor to senior management and defines and enforces standards of accountability, all with a view to enabling senior management to execute their responsibilities fully and in the best interests of the Company and its stockholders.

Our Board and Committee Structure

Upon Ms. Clegg’s resignation in January 2024, the size of the Board was reduced to seven members and remains at seven members. The Board has established three standing committees to assist it in carrying out its responsibilities: the Audit Committee, the Nominating and Corporate Governance Committee and the Human Resources and Compensation Committee. Each of the committees operates under its own written charter adopted by the Board, which such charters are available on our website.

|  | Members |  |  | Independence |  |  | Meetings Held During 2023 |
Board of Directors |  |  | 7 |  |  |  | 86 | % |  |  | 11 |
Audit Committee |  |  | 3 |  |  |  | 100 | % |  |  | 6 |
Human Resources and Compensation Committee |  |  | 3 |  |  |  | 100 | % |  |  | 7 |
Nominating and Corporate Governance Committee |  |  | 4 |  |  |  | 100 | % |  |  | 7 |

GrafTech’s Corporate Governance Guidelines provide that directors are expected to attend Board meetings and meetings of committees on which they serve, to spend the time needed and meet as frequently as necessary to properly discharge their responsibilities and to ensure that other existing and future commitments do not materially interfere with their responsibilities as members of the Board.

Corporate Governance Best Practices
•  Majority of directors are independent |  | •  Executive sessions of independent and non-management directors
•  Majority voting standard (unless election is contested) and resignation policy for directors in uncontested elections |  | •  Stock ownership requirements for independent directors and executives
•  Board committees composed of entirely independent directors |  | •  Annual board and committee self-assessments
•  Orientation program for new directors |  | •  Directors encouraged to attend continuing education programs
•  Maintain an insider trading policy, which includes a prohibition on hedging securities |  | •  Maintain a review and approval policy for related party transactions
•  Director matrix that includes consideration of self-identified diversity characteristics, such as gender, race and ethnicity |  |

Executive Compensation

As required under the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Securities Exchange Act of 1934 (the “Exchange Act”), we provide our stockholders the opportunity to vote, on a non-binding, advisory basis, to approve the compensation of our named executive officers (“NEOs”) as disclosed in this Proxy Statement. We are again asking you to approve, on an advisory basis, the compensation of our NEOs, as disclosed in this Proxy Statement. We are currently conducting this advisory vote, commonly known as a “say-on-pay” vote, every year

|  | GrafTech International Ltd. | 2024 Proxy Statement / 7

##### Table of Contents

and expect to hold the next say-on-pay vote in connection with the annual meeting of stockholders to be held in 2025. We also expect to hold the next vote on the frequency of such say-on-pay vote at our annual meeting of stockholders to be held in 2025. For more information, please see “Proposal 3 Approve, on an Advisory Basis, our Named Executive Officer Compensation” below.

Compensation Philosophy

We believe that NEO compensation should be focused on promoting Company performance and stockholder value. To achieve these goals, our NEO compensation program emphasizes pay-for-performance and aligning the interests of our NEOs with those of our stockholders through the use of long-term incentives and the encouragement of equity ownership. Under our pay-for-performance philosophy, a substantial component of executive compensation is variable and directly or indirectly tied to Company financial and operational performance. The goal is to reward our executive team for their leadership in meeting key near-term goals and objectives while also positioning the Company to generate sustainable long-term stockholder value.

In addition, our NEO compensation program is designed to be competitive with our peers and allows us to recruit, retain and motivate employees who play a significant role in our current and future success. Please read the “Compensation Discussion and Analysis” section below and the related tables and narratives for more information about the compensation of our NEOs.

We Reward Based On |  | Key Features
•  Company annual performance relative to pre-established financial and operational goals |  | •  No excise tax gross-ups in the event of a change in control
•  Long-term stockholder value creation |  | •  Clawback policy
|  | •  No repricing or repurchasing of stock options without stockholder approval
|  | •  Double-trigger vesting of long-term equity incentive awards upon change in control

On February 23, 2024, Mr. Undavia filed another Schedule 13D with the SEC that appeared to be a refiling of his Schedule 13D filed on February 12, 2024, but with all of the text readable.

On February 27, 2024, Mr. Undavia filed a Schedule 13D/A with the SEC that appeared to be identical to the Schedule 13D filed on February 23, 2024, other than the correction of certain errors, including the removal of certain non-affiliated signatures to the Engagement and Indemnification Agreement attached thereto.

On March 1, 2024, Mr. Undavia notified the Company that he had acquired beneficial ownership of an additional 193,994 shares of the Company’s common stock.

On March 8, 2024, the Nominating and Corporate Governance Committee met at a regularly scheduled meeting to discuss, among other items, the status of the due diligence with respect to Mr. Undavia and Ms. Petigny. On that same day, the Company received a report from a third party who had assisted the Company in conducting certain due diligence matters with respect to Mr. Undavia and Ms. Petigny.

On March 11, 2024, Mr. Keizer and Ms. Fine met virtually with Mr. Undavia to ask follow-up questions of Mr. Undavia with respect to the results of the Company’s due diligence on each of Mr. Undavia and Ms. Petigny.

On March 12, 2024, Mr. Undavia provided notice to the Company that he was withdrawing the nomination of Ms. Petigny.

On March 12, 2024, in light of the nomination of Mr. Undavia, the Nominating and Corporate Governance Committee met to discuss and assess the experience, qualifications, skills and other attributes of Ms. Fine, Mr. Taccone and Mr. Undavia. Following discussion, the Nominating and Corporate Governance Committee determined that, based on the information provided by Mr. Undavia and interviews conducted with Mr. Undavia, Mr. Undavia lacked the experience, qualifications, skills and other attributes required to add significant value or meaningful insight to the Board’s consideration of the key issues facing the Company. Having determined that Mr. Undavia would not be additive to the Board’s composition, the Nominating and Corporate Governance Committee reconfirmed its recommendation to the Board that the Board nominate Ms. Fine and Mr. Taccone for re-election at the Annual Meeting.

Later on March 12, 2024, the Board met to, among other things, determine which Director candidates to nominate and recommend for election at the Annual Meeting. The Nominating and Corporate Governance Committee reported on its evaluation of each of Ms. Fine, Mr. Taccone and Mr. Undavia, and then reconfirmed its recommendation to nominate and recommend Ms. Fine and Mr. Taccone for re-election at the Annual Meeting. The Board, acting on such recommendation, reconfirmed its nomination and recommendation of Ms. Fine and Mr. Taccone for re-election at the Annual Meeting and recommended against Mr. Undavia.

Board of Directors

Our business and affairs are managed under the direction of our Board. Under our Amended Certificate of Incorporation, the number of directors is fixed by our Board, but will not be fewer than three directors, nor more than eleven (11) directors. The Board currently consists of seven (7) directors.

Our Amended Certificate of Incorporation provides that our Board be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with the directors serving three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our directors are divided among the three classes as follows:

| • |  | the Class I directors are Diego Donoso and Michel J. Dumas, and their terms will expire at the annual meeting of stockholders to be held in 2025;

| • |  | the Class II directors are Jean-Marc Germain, Henry R. Keizer and Marcel Kessler, and their terms will expire at the annual meeting of stockholders to be held in 2026; and

| • |  | the Class III directors are Debra Fine and Anthony R. Taccone, and their terms will expire at this Annual Meeting.

Our By-Laws provide that the presence of a majority of the total number of directors will be required to constitute a quorum. Our By-Laws further provide that the Board shall elect at least a Chief Executive Officer, Chief Financial Officer, President, Treasurer and Secretary, and may elect other officers, such as a Chairman, as may from time to time appear necessary or advisable in the conduct of the affairs of the Company. While this matter relates to corporate governance, it also relates to succession planning, and it is in the best interests of the Company for the Board to make a determination with respect to this matter on a case-by-case basis as part of the succession planning process. Currently, our Chairman is Henry R. Keizer and our Interim CEO and President is Timothy K. Flanagan. The Nominating and Corporate Governance Committee will periodically consider the size and structure of the Board and report the results of its review and any recommendations for change to the Board.

The classification of the Board as described above and the other provisions of the Amended Certificate of Incorporation may be amended only by the affirmative vote of the holders of 66-2/3% or more of the voting power of our outstanding common stock.

Director Independence

Our Board has undertaken a review of the independence of the directors on our Board. Based on this review, the Board has determined that six (6) current members of the Board (Diego Donoso, Michel J. Dumas, Debra Fine, Jean-Marc Germain, Henry R. Keizer and Anthony R. Taccone) qualify as “independent” under the NYSE listing standards. Mr. Kessler does not qualify as independent under the NYSE listing standards as he previously served as our Chief Executive Officer and President. Our Board previously undertook a review of the independence of our former members. Based on this review, former members Brian L. Acton, Catherine L. Clegg and Leslie D. Dunn qualified as “independent” under NYSE listing standards. Former members David Gregory and Denis A. Turcotte also did not qualify as “independent” under the NYSE listing standards given their relationship with Brookfield Corporation (“Brookfield”) a former controlling stockholder of the Company.

In making these determinations, our Board considered any current and prior relationships or transactions that each director has with the Company and other information provided by each director concerning his or her background, employment and affiliations, including the beneficial ownership of our capital stock by each director and the transactions involving them described in “— Director Compensation Program” and “Certain Relationships and Related Party Transactions.” Our Board considered the Company’s purchase in 2023 of access to steel industry research data from a company of which Anthony R. Taccone is a partner. The amount involved was well below $120,000. The Board also considered the approximately $175,000 payment made to Union Carbide Corporation, a subsidiary of Dow Inc. (“Dow”), where Mr. Donoso was previously employed, relating to retiree medical, life, and prescription expenses pursuant to an arrangement that has been in place for over 30 years, since GrafTech was affiliated with Union Carbide Corporation. The Board concluded that these transactions, respectively, would not interfere with Mr. Taccone’s and Mr. Donoso’s exercise of independent judgment in carrying out the responsibilities of a director and thus did not impair either of their independence. The Board also considered that Mr. Keizer serves as a trustee of the BlackRock Multi-Asset Fund Complex where he serves as a director of approximately 150 registered investment companies within the fund complex and, as of December 31, 2023, BlackRock owned approximately 5.6% of our common stock. The Board concluded that such position did not interfere with his independence.

Committees of the Board of Directors

The Board has established three standing committees to assist it in carrying out its responsibilities: the Audit Committee, the Nominating and Corporate Governance Committee and the Human Resources and Compensation Committee. Each of the committees operates under its own written charter adopted by the Board, which are available on our website. The membership and the function of each of the existing committees are described below.

Board Meetings

During fiscal year 2023, our Board held 11 meetings, including regularly scheduled and special meetings. Our directors’ average attendance was 97%, and each current director, as well as former directors Brian Acton, Catherine Clegg, Leslie Dunn, Dave Gregory and Denis Turcotte, attended at least 75% of the aggregate number of 2023 meetings of our Board and the committees on which he or she served during their respective tenures as director. We encourage, but do not require, our directors to attend each annual meeting of stockholders. All of our then-current directors attended the 2023 annual meeting of stockholders.

Director Skills and Qualifications Criteria

The Nominating and Corporate Governance Committee reviews at least annually the skills, qualifications and characteristics for election of new and continuation of existing directors. The criteria considered in selecting director nominees reflect applicable law, the listing standards of the NYSE, as well as a candidate’s integrity, strength of character, judgment, business experience, specific areas of expertise, ability to devote sufficient time to attendance at and preparation for Board meetings, factors relating to the composition of the Board (including its size and structure) and principles of diversity. The Nominating and Corporate Governance Committee will consider qualified nominees recommended by stockholders for membership on the Board. If a stockholder wishes to recommend an individual for membership on the Board, that recommendation can be sent to the attention of the Corporate Secretary, GrafTech International Ltd., 982 Keynote Circle, Brooklyn Heights, Ohio 44131. Stockholders proposing director nominations must comply with the advance notice and specific information requirements in our By-Laws, which include, among other things, the disclosure of hedging, derivative interests and other material interests of the nominating stockholder and director nominee. In addition, each director nominee proposed by a stockholder must deliver a statement whether he or she agrees to, promptly following the stockholder meeting at which such nominee is elected or re-elected, tender an irrevocable advance resignation in accordance with our By-Laws and Corporate Governance Guidelines.

The Nominating and Corporate Governance Committee maintains a Board of Directors Diversity Policy, which illustrates its attention and desire to preserve an environment free from discrimination on the basis of, among other things, race, color, religion, nationality, age and gender.

The Nominating and Corporate Governance Committee recommends to the Board all nominees to be proposed by the Company for election to the Board, as well as actions with respect to individuals nominated by third parties.

Directors whose positions, responsibilities or commitments change materially after they were elected to the Board are required to inform the Nominating and Corporate Governance Committee and volunteer to resign from the Board so that the Nominating and Corporate Governance Committee may have an opportunity to review the appropriateness of continued membership under the circumstances, including with respect to independence, and make recommendations to the Board, which could accept the volunteered resignation but need not do so.

Directors are expected to serve on at most a limited number of other public company boards. Prior to accepting an invitation to serve on another public company board, directors must advise the Nominating and Corporate Governance Committee and must receive written confirmation from the head of the legal department that there are no legal or regulatory impediments to such service.

The Nominating and Corporate Governance Committee leads the effort to identify and recruit candidates to join the Board. The Nominating and Corporate Governance Committee utilizes a variety of methods and processes to identify potential director candidates, including through reputable third-party search firms, unsolicited recommendations from other third-party search firms, and referrals from current or past members of the Board. In this context, the Nominating and Corporate Governance Committee’s view is that the Board should reflect a balance between the experience that comes with longevity of service on the Board and the need for renewal and fresh perspectives. As such, the Nominating and Corporate Governance Committee does not support mandatory director term limits as a Board turnover mechanism. However, in order to encourage Board refreshment, directors will not be up for re-election when their class is otherwise up for re-election for a new three-year term if they are 75 or over or will reach the age of 75 within such term. The Nominating and Corporate Governance Committee and the Board, in their respective exercise of discretion, may elect to waive this guideline and renominate a director regardless of his or her age. The Nominating and Corporate Governance Committee does believe that periodically adding new voices to the Board can help the Company adapt to a changing business environment and Board renewal continues to be a priority.

Director Orientation and Continuing Education

All new directors participate in an orientation program (the “Orientation Program”) reasonably promptly after they are elected. The Orientation Program includes presentations by senior management and internal and independent auditors to familiarize new directors with strategic plans, significant financial, accounting and risk management issues and compliance programs (including the Company’s Code of Conduct and Ethics and other applicable policies). In addition, the Orientation Program can include visits to headquarters and, to the extent practical, certain of the significant facilities of the Company. All other directors are welcome to attend the Orientation Program.

All directors are also encouraged to participate in Continuing Education Programs offered by the NYSE and other organizations, and the Company will reimburse directors for reasonable costs associated therewith.

Director Compensation Program

Our non-employee directors receive compensation for service on the Board. The Nominating and Corporate Governance Committee is responsible for reviewing and making recommendations to the Board regarding the form and amount of compensation for our non-employee directors. All of our non-employee directors are paid under the same compensation program, except as noted below with respect to the directors designated by Brookfield. As of December 14, 2023, there were no longer any Brookfield designated directors on our Board. Our non-employee directors’ out-of-pocket business travel and accommodation expenses are reimbursed by us. Directors who are employees of the Company do not receive any additional compensation for service on our Board.

In December 2022, the Nominating and Corporate Governance Committee and Board reviewed and revised the director compensation program, effective January 1, 2023, to align the director compensation program with programs of similarly situated companies with the understanding that a near-term goal of the Nominating and Corporate Governance Committee and Board was to decrease the size of the Board. At the time, the Board consisted of eleven (11) members The Board has since been reduced to seven (7) members. Under the revised director compensation program, the non-employee director annual retainer is comprised of two components: (i) a cash retainer in the amount of $100,000 and (ii) a Restricted Stock Unit (“RSU”) grant in the amount of $100,000. The RSUs generally will be granted immediately after the conclusion of our annual meeting each year and generally vest in full on the six-month anniversary of the grant date. Directors who are appointed at times other than the annual meeting of stockholders will receive their RSU grant shortly after their appointment on similar terms. Directors may elect to defer their receipt of the cash retainer and RSUs, in which case they will be awarded instead with deferred share units (“DSU”) and deferred RSUs (“deferred RSUs” or “DRSUs”), respectively, under the Equity Plan. The DSUs and deferred RSUs can be settled in one of two ways as elected by the director: (i) as soon as practicable following the date of termination of the director’s service in a single lump sum or (ii) in substantially equal 20% installments on the first five annual anniversaries of the date of termination of the director’s service. Accordingly, the director compensation program beginning on January 1, 2023 is as follows:

Description |  | Annual Fee* |
Non-Employee Director Cash Retainer |  | $ | 100,000 |
Non-Employee Director RSU Grant |  | $ | 100,000 |
Chairman of the Board Cash Retainer |  | $ | 100,000 |
Presiding Independent Director Cash Retainer** |  | $ | 20,000 |

Director Deferred Fee Plan for Non-Employee Directors

We maintain an Amended and Restated GrafTech International Ltd. Director Deferred Fee Plan (as amended, the “Director Deferred Fee Plan”), which provides non-employee directors (other than Brookfield designated directors) (“Eligible Directors”) with the opportunity to defer payment of cash retainer fees paid for service on the Board and any committees, at their election (subject to our Non-Employee Director Stock Ownership Policy described below). Newly-elected Eligible Directors are required to make an election to defer payment of cash fees prior to their appointment on the Board, while existing Eligible Directors are required to make their election by December 17 prior to the beginning of the next calendar year. The director year under the Director Deferred Fee Plan generally begins on April 1 and continues through March 31 of the succeeding year; provided, however, that beginning in 2024 the director year began on January 1. An Eligible Director who chooses to have any portion of their cash fees deferred will have an account established in which the fees that would have been paid to the Eligible Director shall instead be credited with DSUs, the number which shall be determined by dividing (i) the amount of fees payable on such date they are deferred by (ii) the closing price of one share of our common stock as reported on the NYSE on such date. All DSUs will accrue dividend equivalents that will be credited to the Eligible Director as additional DSUs to the extent that the Board declares dividends on the common stock of the Company. The DSUs shall be fully vested and nonforfeitable at all times. All whole DSUs will be settled in shares of our common stock after the Eligible Director’s termination of service on the Board while any fractional DSUs will be settled in cash.

The Director Deferred Fee Plan was further amended and restated in December 2022, with such amendments taking effect on April 1, 2023. The amendments, among other things, permit an Eligible Director to defer the settlement of the DSUs in substantially equal 20% installments on the first five annual anniversaries of the date of termination of the Eligible Director’s service (in the alternative to settling such DSUs as soon as practicable following the date of termination of service as an Eligible Director in a single lump sum). The amendments also changed the director year starting in 2024 as described above.

Non-Employee Director Stock Ownership Policy

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”). DSUs, RSUs and deferred RSUs will count towards the Stock Threshold. Any common stock received upon the vesting of RSUs must be held and may not be sold until the Stock Threshold is met. The Stock Threshold will be calculated each year on December 1 and in the event that a director who previously met the Stock Threshold no longer does, that director will need to acquire more common stock or, to the extent determined by the Board, elect to receive a portion of his or her total cash director fees in DSUs for the following director year in order to satisfy the Stock Threshold by the following December. As of March 13, 2024, all of the independent directors are expected to comply with the Non-Employee Director Stock Ownership Policy in the prescribed time frame.

Risk Oversight

The Board oversees the management of the Company’s risk exposure through the following framework: management regularly provides to the Board updated information concerning strategic, operational and emerging risks to the Company’s primary business goals and initiatives in each geographic area and each functional group, as well as the Company’s efforts to mitigate those risks.

The Board is responsible for understanding the Company’s most significant risks, ensuring that management responds appropriately, and making risk-informed strategic decisions. The Board monitors risk exposure to ensure that it is in line with the Company’s overall tolerance for, and ability to manage, risk.

Our Audit Committee, which is made up solely of independent directors who have had extensive experience in providing strategic and advisory services to other companies, assists the Board in evaluating the risks the Company faces as well as our policies for risk management and assessment.

| • |  | Annually assesses the Company’s compensation programs to determine if any elements of these plans create an inappropriate level of risk and to evaluate management’s methods to mitigate any potential risks.

The Nominating and Corporate Governance Committee:

| • |  | Oversees risks associated with Board and committee composition, including the annual self-assessments of the Board and its committees and oversees the implementation and reporting back of the results.

The Board’s role in risk oversight complements our leadership structure, with senior management responsible for assessing, managing and mitigating our risk exposure and the Board and its committees overseeing those efforts. We believe that this is an effective approach to addressing the risks we face and supports our current Board leadership structure, as it allows our independent directors to evaluate our risks and our risk management and assessment policies, including through the fully independent Audit Committee, with ultimate oversight by the full Board. In particular, the Human Resources and Compensation Committee has determined that none of our executive compensation policies and practices create any risks that are reasonably likely to have a material adverse effect on the Company.

Communications from Stockholders and Other Interested Parties

The Company values your feedback. Any stockholder or interested party who desires to contact the Company’s Chairman, the independent or non-management directors as a group or the other members of the Board may do so by writing to the Corporate Secretary, GrafTech International Ltd., at 982 Keynote Circle, Brooklyn Heights, Ohio 44131, Attention: Corporate Secretary. Any such communication should state the number of shares owned, if applicable. The Corporate Secretary will forward to the Chairman any such communication addressed to the Chairman, the independent or non-employee Directors as a group or to the Board generally, and will forward such communication to other Board members, as appropriate, provided that such communication addresses a legitimate business issue. Any communication relating to accounting, auditing or fraud will be forwarded immediately to the Chair of the Audit Committee.

Certain Relationships and Related Party Transactions

Under SEC rules, a related person is an executive officer, director, nominee for director or beneficial holder of more than 5% of any class of our voting securities since the beginning of the last fiscal year or an immediate family member of any of the foregoing. We have a written related party transaction policy, pursuant to which directors (including director nominees), executive officers and employees are required to report any transactions or circumstances that may create or appear to create a conflict between the personal interests of the individual and our interests, regardless of the amount involved. Our head of legal reports these transactions to the Audit Committee of the Board, which is responsible for evaluating each related party transaction and, if necessary, making a recommendation to the disinterested members of the Board as to whether the transaction at issue is fair, reasonable and within our policy and whether it should be ratified and approved. The Audit Committee, in making its recommendation, considers various factors, including the benefit of the transaction to us, the terms of the transaction and whether they are at arm’s length and in the ordinary course of our business, the direct or indirect nature of the related person’s interest in the transaction, the size and expected term of the transaction, and other facts and circumstances that bear on the materiality of the related party transaction under applicable law and listing standards.

Other than the transactions described below, since January 1, 2023, there has not been, and there is not currently proposed, any transaction or series of similar transactions to which we were or will be a participant in which the amount involved exceeded or will exceed $120,000 and in which any related person had or will have a direct or indirect material interest.

Brookfield Transactions

We have engaged in transactions with Brookfield, a former holder of more than 5% of our common stock, since January 1, 2023. These transactions include ongoing obligations under the Registration Rights Agreement (as defined below), Stockholder Rights Agreement and Tax Receivable Agreement (as defined below), each with Brookfield.

Registration Rights Agreement

We and Brookfield entered into a registration rights agreement (the “Registration Rights Agreement”) in connection with our IPO. The Registration Rights Agreement provides Brookfield with certain demand registration rights, including shelf registration rights, in respect of any shares of our common stock or any of our debt securities held by it, subject to certain conditions and limitations. Brookfield is entitled to a limited number of demand registrations. In addition, in the event that we register additional shares of common stock or debt securities for sale to the public, we will be required to give notice of such registration to Brookfield of our intention to effect such a registration, and, subject to certain limitations, include any shares of common stock or debt securities requested to be included in such registration held by it. We will be required to bear the registration expenses, other than underwriting discounts and commissions, associated with any registration of shares of common stock or debt securities pursuant to the Registration Rights Agreement. The Registration Rights Agreement includes customary indemnification provisions in favor of Brookfield, its affiliates, directors and officers against certain losses and liabilities (including reasonable legal expenses) resulting from any untrue statement or omission of material fact in any registration statement or prospectus pursuant to which Brookfield sells shares of our common stock or our debt securities, unless such liability arose from Brookfield’s misstatement or omission and Brookfield has agreed to indemnify us against losses caused by its misstatements or omissions, subject to certain limitations.

Stockholder Rights Agreement

We and Brookfield entered into the Stockholder Rights Agreement in connection with our IPO. The Stockholder Rights Agreement expires once Brookfield ceases to own any of our common stock. On November 6, 2019, we and Brookfield amended the Stockholder Rights Agreement to reimburse Brookfield for the services of the Brookfield directors for (a) cash compensation consistent with the compensation received by other non-management members of the Board and (b) to the extent a Brookfield director serves as Chairman of the Board, any additional compensation as may be approved by the unaffiliated independent members of the Board for such service as Chairman of the Board.

Tax Receivable Agreement

We and Brookfield entered into a tax receivable agreement (the “Tax Receivable Agreement”) in connection with our IPO. The Tax Receivable Agreement provides the right to receive future payments from us to certain of our pre-IPO stockholders (the “Existing Stockholders”) of 85% of the amount of cash savings, if any, in U.S. federal income tax and Swiss tax that we and our subsidiaries realize as a result of the utilization of certain tax assets attributable to periods prior to our IPO, including certain federal net operating losses (“NOLs”), previously taxed income under Section 959 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”), foreign tax credits, and certain NOLs in GrafTech Switzerland S.A. (collectively, the “Pre-IPO Tax Assets”). In addition, we will pay interest on the payments we make to the Existing Stockholders with respect to the amount of this cash savings from the due date (without extensions) of our tax return where we realize this savings to the payment date at a rate equal to the forward looking term rate based on the secured overnight financing rate (“SOFR”) administered by the Federal Reserve Bank of New York for a one-month period plus 0.10% plus 100 basis points per annum.

For purposes of the Tax Receivable Agreement, cash savings in income tax are computed by reference to the reduction in the liability for income taxes resulting from the utilization of the tax benefits subject to the Tax Receivable Agreement. The term of the Tax Receivable Agreement commenced on April 23, 2018 and will continue until there is no potential for any future tax benefit payments.

Our counterparties under the Tax Receivable Agreement will not reimburse us for any payments previously made if such tax benefits are subsequently disallowed (although future payments would be adjusted to the extent possible to reflect the result of such disallowance). As a result, in such circumstances we could make payments under the Tax Receivable Agreement that are greater than our actual cash tax savings.

While the actual amount and timing of any payments under the Tax Receivable Agreement will vary depending upon a number of factors, including the amount and timing of the taxable income we and our subsidiaries generate in the future, and our subsidiaries’ use of Pre-IPO Tax Assets, as of December 31, 2023, we expect that, based on current tax laws, payments under the Tax Receivable Agreement relating to the Pre-IPO Tax Assets will total approximately $70 million. This figure does not account for our Pre-IPO Tax Assets attributable to previously taxed income under Section 959 of the Code, the value of which is highly speculative, and certain NOLs in GrafTech Switzerland S.A., which we expected to have nominal value at the time of our IPO. As of December 31, 2023, we have made payments of approximately $58.1 million related to the Tax Receivable Agreement. We expect that, based on current tax laws, future payments under the Tax Receivable Agreement relating to the Pre-IPO Tax Assets will be approximately $11.2 million in the aggregate.

Any future changes in the utility of the Pre-IPO Tax Assets will impact the amount of the liability that will be paid to the Existing Stockholders. Changes in the utility of these Pre-IPO Tax Assets will be recorded in the provision for income taxes and any changes in the obligation under the Tax Receivable Agreement will be recorded in other (income) expense, net in the consolidated statements of operations. We plan to use cash flow from operations and availability under our credit facilities to fund this obligation.

If we undergo a Change of Control (as defined in the Tax Receivable Agreement), the Tax Receivable Agreement will terminate and we will be required to make a payment equal to the present value of future payments under the Tax Receivable Agreement, which payment would be based on certain assumptions, including those relating to our and our subsidiaries’ future taxable income. Additionally, if we sell or otherwise dispose of any of our subsidiaries in a transaction that is not a Change of Control, we will be required to make a payment equal to the present value of future payments under the Tax Receivable Agreement attributable to the Pre-IPO Tax Assets of such subsidiary that is sold or disposed of, applying the assumptions described above.

The Tax Receivable Agreement provides that in the event that we breach any of our material obligations under it, whether as a result of our failure to make any payment when due (subject to a specified cure period), failure to honor any other material obligation under it or by operation of law as a result of the rejection of it in a case commenced under the U.S. Bankruptcy Code or otherwise, then all of our payments and other obligations under the Tax Receivable Agreement will be accelerated and will become due and payable applying the same assumptions described above. Such payments could be substantial and could exceed our actual cash tax savings under the Tax Receivable Agreement.

Certain transactions by the Company could cause it to recognize taxable income (possibly material amounts of income) without a current receipt of cash. Payments under the Tax Receivable Agreement with respect to such taxable income would cause a net reduction in our available cash. For example, transactions giving rise to cancellation of debt income, the accrual of income from original issue discount or deferred payments, a “triggering event” requiring the recapture of dual consolidated losses, or “Subpart F” income would each produce income with no corresponding increase in cash. In these cases, we may use some of the Pre-IPO Tax Assets to offset income from these transactions and, under the Tax Receivable Agreement, would be required to make a payment to the Existing Stockholders even though we receive no cash from such income.

Because we are a holding company with no operations of our own, our ability to make payments under the Tax Receivable Agreement is dependent on the ability of our subsidiaries to make distributions to us. To the extent that we are unable to make payments under the Tax Receivable Agreement for specified reasons, such payments will be deferred and will accrue interest at a rate of SOFR plus 0.10% plus 100 basis points per annum until paid.

In the event that any determinations must be made under or any dispute arises involving the Tax Receivable Agreement, the Existing Stockholders will be represented by Brookfield Capital Partners IV GP, Ltd. In any such instance, should any representatives of Brookfield Capital Partners IV GP, Ltd. then be serving on our Board, such directors will be excluded from decisions of the Board related to the relevant determination or dispute.

The Dow Inc. Transaction

Mr. Donoso was elected to the Board in June 2023. Mr. Donoso retired in April 2023 from Dow, an American multinational materials science company. From 2012 until his retirement, Mr. Donoso served as President of Packaging & Specialty Plastics of Dow. In January 2024, GrafTech made a payment to Union Carbide Corporation, a subsidiary of Dow, in the amount of $174,664.60 relating to retiree medical, life, and prescription expenses pursuant to an arrangement that has been in place for over 30 years, since GrafTech was affiliated with Union Carbide Corporation.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act, requires our directors, officers and beneficial owners of 10% or more of our shares of common stock to file reports with the SEC. We assist our directors and officers by monitoring transactions and completing and filing these reports on their behalf. Based on our records and other information, we believe that all reports that were required to be filed under Section 16(a) during 2023 were timely filed.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information as of March 13, 2024 regarding the beneficial ownership of our common stock by:

| • |  | each person or group who beneficially owns more than 5% of our outstanding shares of common stock;

| • |  | each of our named executive officers;

| • |  | each of our directors and director nominees; and

| • |  | all of our executive officers and directors as a group.

Beneficial ownership for the purposes of the following table is determined in accordance with the rules and regulations of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting of securities, or to dispose or direct the disposition of securities or has the right to acquire such powers within 60 days. For purposes of calculating each person’s percentage ownership, common stock issuable pursuant to options exercisable or awards payable within 60 days are included as outstanding and beneficially owned for that person or group, but are not deemed outstanding for the purposes of computing the percentage ownership of any other person. Except as disclosed in the footnotes to this table and subject to applicable community property laws, we believe that each beneficial owner identified in the table possesses sole voting and investment power over all common stock shown as beneficially owned by the beneficial owner.

The percentage of beneficial ownership is based on 256,831,870 shares of common stock issued and outstanding on March 13, 2024. Unless otherwise indicated in the table or footnotes below, the address for each beneficial owner is c/o GrafTech International Ltd., 982 Keynote Circle, Brooklyn Heights, OH 44131.

Policies on Transactions in Company Stock, Including Anti-Hedging Provisions

All of our executive officers, directors and other employees are prohibited from engaging in hedging or monetizing transactions with respect to our securities. “Hedging transactions” or “monetizing transactions” can be accomplished through a number of possible mechanisms, including through the use of financial instruments (such as prepaid variable forwards, equity swaps, collars and exchange funds) or through other transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our securities, often in exchange for all or part of the potential for upside appreciation in these securities. Because hedging transactions might permit an executive officer, director or other employee to continue to own our securities, whether obtained through our equity compensation plans or otherwise, without the full rewards and risks of ownership, such hedging or monetization transactions are prohibited.

We also prohibit our executive officers, directors and other employees from engaging in put, call or other derivative transactions relating to our securities on an exchange or in any other organized market. A put is an option or right to sell a security at a specific price before a set date, and a call is an option or right to buy a security at a specific price before a set date. Because a transaction in options in our securities would, in effect, be a bet on the short-term movement of our securities and may also focus attention on short-term performance at the expense of our long-term objectives, our executive officers, directors and other employees are prohibited from engaging in such transactions. Additionally, our executive officers, directors and other employees are also prohibited from engaging in short sales of our securities. A short sale of a security is the sale of a security that the seller does not own. Because a short sale of our securities would, in effect, be a bet that the value of the security will decline, allowing a short sale could create perverse incentives for the seller.

Proposal 1 Elect Two Directors for a Three-Year Term or Until Their Successors Are Elected and Qualified

Under our Amended Certificate of Incorporation, the number of members of our Board is fixed from time to time by the Board and may be increased or decreased by the majority of directors then in office. The number of members will not be fewer than three (3) directors, nor more than eleven (11) directors. The Amended Certificate of Incorporation further provides that the directors shall be divided into three classes, designated Class I, Class II and Class III, and each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board. Directors are elected by stockholders for terms of three years and hold office until their successors are duly elected and qualified. One of the three classes is elected each year to succeed the directors whose terms are expiring.

Our Board currently consists of seven (7) members and is divided into three classes of directors, with Class I containing two (2) directors, Class II containing three (3) directors, and Class III containing two (2) directors. The terms of the directors in Class III expire at this Annual Meeting. Our current Class III directors are Debra Fine and Anthony R. Taccone.

Ms. Fine and Mr. Taccone are standing for re-election at the Annual Meeting as Class III directors. Each of these director nominees was recommended for nomination to the Board by the Nominating and Corporate Governance Committee.

If elected, Ms. Fine and Mr. Taccone will hold office for a three-year term until the 2027 Annual Meeting and or until their successor is elected and qualified, subject to earlier retirement, resignation or removal. Unless otherwise instructed, we will vote all proxies we receive “FOR” Ms. Fine and Mr. Taccone. If a nominee becomes unavailable to serve, we will vote the shares represented by proxies for the election of such other person as the Board may recommend.

As described previously, the Undavia Group has notified GrafTech of its intent to nominate Nilesh Undavia for election as director at the Annual Meeting in opposition to the nominees recommended by the GrafTech Board. As a result, assuming such nominee is in fact proposed for election at the Annual Meeting and such nomination has not been withdrawn by the Undavia Group, the election of directors will be considered a contested election and, as provided under Article III, Section 2 of GrafTech’s By-Laws, directors will be elected on a plurality basis. This means that the two (2) director nominees receiving the greatest number of votes cast “FOR” their election will be elected. Abstentions and any broker non-votes will be counted for purposes of determining if there is a quorum at the Annual Meeting for this vote but will not be counted as votes cast and will result in the applicable nominee(s) receiving fewer votes cast “FOR” such nominee(s).

The Board does not endorse the Undavia Group Nominee, and unanimously recommends that you use the WHITE proxy card to vote “FOR” ONLY the election of the two (2) nominees proposed by the Board (Debra Fine and Anthony R. Taccone). The Board strongly urges you to discard and NOT to vote using any [•] proxy card that may be sent to you by the Undavia Group. If you have already voted using a [•] proxy card sent to you by the Undavia Group, you have every right to change your vote and we strongly urge you to revoke that proxy by using the WHITE proxy card to vote in favor of ONLY the two (2) nominees recommended by the Board — by Internet, telephone or by signing, dating and returning the enclosed WHITE proxy card in the postage-paid envelope provided. Only the latest validly executed proxy that you submit will be counted — any proxy may be revoked at any time prior to its exercise at the Annual Meeting.

In the event that Undavia Group withdraws its nominee, abandons its solicitation or fails to comply with the universal proxy rules after a stockholder has already granted proxy authority, stockholders can still sign and date a later submitted WHITE proxy card.

In the event that the Undavia Group withdraws its nominee, abandons its solicitation or fails to comply with the universal proxy rules, the election will be considered uncontested, any votes cast in favor of any Undavia Group Nominee, as applicable, will be disregarded and not be counted, whether such vote is provided on the Company’s WHITE proxy card or the Undavia Group’s [•] proxy card, and directors will be elected on a majority basis of the remaining votes.

##### Table of Contents

Although the Company is required to include all nominees for election on its proxy card, for additional information regarding the Undavia Group nominee and any other related information, please refer to the Undavia Group’s proxy statement. You may receive solicitation materials from the Undavia Group, including proxy statements and [•] proxy cards. GrafTech is not responsible for the accuracy or completeness of any information provided by or relating to the Undavia Group or its nominee contained in solicitation materials filed or disseminated by or on behalf of the Undavia Group or any other statements the Undavia Group may make. Stockholders will be able to obtain, free of charge, copies of all proxy statements, any amendments or supplements thereto and any other documents (including the WHITE proxy card) when filed by the applicable party with the SEC in connection with the Annual Meeting at the SEC’s website (http://www.sec.gov).

If you are a registered holder and submit a validly executed WHITE proxy card but do not specify how you want to vote your shares with respect to the election of directors, then your shares will be voted in line with the Board’s recommendation with respect to the proposal, i.e., “FOR” the two (2) nominees proposed by the Board and named in this proxy statement. You are permitted to vote for fewer then two (2) nominees. If you vote for fewer than two (2) nominees, your shares will only be voted “FOR” with respect to those nominees you have so marked. However, if you are a registered holder and submit a validly executed WHITE proxy card but vote “FOR” more than two (2) nominees, all of your votes with respect to the election of directors will be invalid and will not be counted. It is therefore important that you do not vote “FOR” more than two (2) nominees so that your vote with respect to this item is counted.

If you are a beneficial holder and properly mark, sign and return your WHITE voting instruction form or use your WHITE voting instruction form to vote via Internet, your shares will be voted as you direct your bank or broker. However, if you sign and return your WHITE voting instruction form but do not specify how you want your shares voted with respect to the election of directors, they will be voted in line with the Board’s recommendation with respect to the proposal, i.e., “FOR” the two (2) nominees proposed by your Board and named in this proxy statement, depending on the bank or broker through which you hold your shares. You are permitted to vote for fewer then two (2) nominees. If you vote for fewer than two (2) nominees, your shares will only be voted “FOR” with respect to those nominees you have so marked. If you are a beneficial holder and you vote “FOR” more than two (2) nominees on your WHITE voting instruction form, all of your votes with respect to the election of directors will be invalid and will not be counted. It is therefore important that you provide specific instructions to your broker or bank regarding the election of Directors so that your vote with respect to this item is counted.

Required Vote

Our By-Laws require that each director receive a majority of the votes properly cast with respect to such director in uncontested elections (i.e., the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee), unless the election of directors at the Annual Meeting is contested. Assuming the Undavia Group Nominee is in fact proposed for election at the Annual Meeting and such nomination has not been withdrawn by the Undavia Group, the election of directors at the Annual Meeting will be considered a contested election and, as provided under Article III, Section 2 of GrafTech’s By-Laws, directors will be elected on a plurality basis. This means that the two (2) director nominees receiving the greatest number of votes cast “FOR” their election will be elected. Abstentions and any broker non-votes will be counted for purposes of determining if there is a quorum at the Annual Meeting for this vote but will not be counted as votes cast and will result in the applicable nominee(s) receiving fewer votes cast “FOR” such nominee(s).

Proposal 2 Ratify the Selection of Deloitte & Touche LLP as our Independent Registered Public Accounting Firm for 2024

The Audit Committee has selected, and the Audit Committee and the Board recommend stockholder ratification of, Deloitte & Touche LLP as our independent registered public accounting firm for the year ended December 31, 2024. The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm retained to audit our consolidated financial statements.

Deloitte & Touche LLP has served as our independent registered public accounting firm since 2015. In order to ensure continuing auditor independence, the Audit Committee periodically considers whether there should be a regular rotation of the independent registered public accounting firm. The members of the Audit Committee and the Board believe that the continued retention of Deloitte & Touche LLP to serve as our independent registered public accounting firm is in the best interest of the Company and its stockholders.

Although ratification by stockholders is not required by law or by our By-Laws, the Audit Committee believes that submission of its selection to stockholders is a matter of good corporate governance. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if the Audit Committee believes that such a change would be in the best interest of the Company and its stockholders. If our stockholders do not ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm, the Audit Committee will reconsider its selection.

Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. They will have the opportunity to make a statement if they choose and will also be available to respond to appropriate questions from stockholders.

Required Vote

Approval of this ratification requires the affirmative vote of a majority of the voting power of the shares present in person or by proxy at the meeting and entitled to vote thereon. Therefore, abstentions will have the effect of votes against this proposal. If your shares are held in the name of your broker or bank, under NYSE rules, the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ended December 31, 2024 is normally considered “routine” and would be the only proposal on this year’s Annual Meeting agenda with respect to which your broker could vote your shares absent your instructions. However, to the extent your broker provides you with the Undavia Group’s proxy materials it will not have discretion to vote on “routine matters,” including this proposal. In such circumstances, if you do not instruct your broker on how to vote your shares regarding the ratification of Deloitte & Touch LLP as our independent registered public accounting firm for the fiscal year ended December 31, 2024, then your shares may not be voted on this matter. We urge you to instruct your broker about how you wish your shares to be voted using the WHITE voting instruction form.

THE AUDIT COMMITTEE AND THE BOARD RECOMMEND THAT YOU VOTE “FOR” THE RATIFICATION OF THE SELECTION OF DELOITTE & TOUCHE LLP TO SERVE AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE 2024 FISCAL YEAR.

Audit Committee Report

Management is responsible for the Company’s financial reporting process, including its system of internal controls, and for the preparation of consolidated financial statements in accordance with GAAP. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an independent audit of the Company’s financial statements and internal controls over financial reporting, in accordance with standards of the U.S. Public Company Accounting Oversight Board (“PCAOB”). The Audit Committee is also responsible for monitoring and reviewing these processes.

The Audit Committee reviewed and discussed the Company’s audited financial statements for fiscal year 2023 (ended December 31, 2023) with the Company’s management, including the acceptability and quality of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. The Audit Committee also reviewed and discussed with Deloitte & Touche LLP the audited financial statements and the matters required by the applicable requirements of the PCAOB and the SEC. Deloitte & Touche LLP provided, and the Audit Committee received, the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. The Audit Committee has discussed with Deloitte & Touche LLP its independence and has considered whether the firm’s provision of non-audit related services to the Company is compatible with maintaining such auditors’ independence.

Based on its discussions with, and its review of information provided by, management and Deloitte & Touche LLP, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Proposal 3 Approve, on an Advisory Basis, our Named Executive Officer Compensation

As required under the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act, we provide our stockholders the opportunity to vote, on a non-binding, advisory basis, to approve the compensation of our NEOs as disclosed in this Proxy Statement.

We believe that NEO compensation should be focused on promoting Company performance and stockholder value.

The vote on this proposal is not intended to address any specific element of compensation; rather, the vote relates to the overall compensation of our NEOs. This vote is advisory only and is not binding. Although the vote is non-binding, our Human Resources and Compensation Committee values the opinions of our stockholders, and our Human Resources and Compensation Committee expects to consider the outcome of the vote when making future compensation decisions for our NEOs. We are currently conducting this advisory vote, commonly known as a “say-on-pay” vote, every year and expect to hold the next say-on-pay vote in connection with the annual meeting of stockholders to be held in 2025. We also expect to hold the next vote on the frequency of such say-on-pay vote at our annual meeting of stockholders to be held in 2025.

Accordingly, we ask our stockholders to vote in favor of the following resolution:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2024 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis and the related tables and accompanying narrative.”

Our executive compensation program is driven by our strategic goals with an emphasis on paying for performance. This program has always relied upon the two elements of competitive base salary and a performance-based annual cash incentive plan, the Short-Term Incentive Plan (“STIP”). The STIP is designed to reward employees based on the financial and operational performance of the Company and is based on the achievement of Adjusted EBITDA and Adjusted Free Cash Flow, as well as certain other corporate objectives, including engagements with the community, total recordable incident rates, and certain training participation rates. See Appendix A to this Proxy Statement for additional information, including how we define Adjusted EBITDA and Adjusted Free Cash Flow and reconciliations to the most directly comparable financial measures calculated and presented in accordance with U.S. GAAP.

Longer term incentive compensation has also been part of our NEO compensation program. Since 2019, we have provided our executive leadership team with long-term incentive program awards under our Equity Plan adopted at the time of our IPO. These equity awards are designed to continue to help retain senior management of the Company and to incentivize them to make decisions with a long-term view and to motivate and influence behavior on their part that is consistent with maximizing value for the stockholders of the Company in a prudent manner. In 2023, we approved grants of time-based stock options, RSUs, and performance-based restricted stock units (“PSUs”) to the NEOs as new awards under the Equity Plan.

2023 Business Summary

2023 was a challenging year for our business, marked by soft industry demand, the residual impact of the temporary suspension of our operations in Monterrey, Mexico that occurred in late 2022, and significantly higher costs. As a result, net sales decreased $660.8 million, or 52%, from $1,281.3 million in 2022 to $620.5 million in 2023, primarily reflecting lower sales volume. A shift in the mix of our business from volume derived from our LTAs to volume derived from non-

LTAs and lower weighted-average realized prices also contributed to the decline in net sales. Net loss for 2023 was $255.3 million compared to a net income of $383.0 million in 2022. Results for 2023 included a goodwill impairment charge of $171 million and a lower of cost or market inventory valuation adjustment of $12 million. Adjusted EBITDA1 for 2023 was $20.5 million compared to $536.5 million in the prior year, with the decline primarily due to lower sales volume, higher costs on a per MT basis, the shift in the mix of our business from LTA volume to non-LTA volume, lower weighted-average realized prices and the impact of a lower of cost or market inventory valuation adjustment recorded in 2023. Adjusted Net (Loss) Income1 decreased $480.4 million from Adjusted Net Income of $379.7 million in 2022 to Adjusted Net Loss of $100.8 million in 2023.

Against this backdrop, we are proactively managing our operating costs, capital expenditures and working capital levels. Specifically, our initiatives to manage working capital led to a more than $100 million reduction in inventory levels in 2023, resulting in positive free cash flow(1) for the year. In 2024, we began executing a set of further initiatives designed to reduce our cost structure and optimize our manufacturing footprint while, at the same time, preserving our ability to deliver excellent customer service and to capitalize on long-term growth opportunities for our Company. These actions include: (1) indefinitely suspending production activities at our St. Marys, Pennsylvania facility, with the exception of graphite electrode and pin machining, as well as indefinitely idling certain assets within our remaining graphite electrode manufacturing footprint; (2) reducing the Company’s overhead structure and expenses; and (3) operating our remaining graphite electrode production facilities at reduced levels, as needed, to align production with our view on market demand.

These initiatives, most notably the indefinite suspension of production at St. Marys and the reduction in Company overhead, are expected to result in annualized cost savings of approximately $25 million once fully implemented, excluding the impact of one-time costs. Of the anticipated cost savings, approximately $15 million are expected to be realized in cost of goods sold with the remainder in selling and administrative expenses. One-time costs are expected to be approximately $5 million, of which the majority are cash-related. In addition to being a key component of the incremental actions we are taking in response to weak market conditions, this will support our efforts to further reduce our inventory levels and manage capital expenditures in 2024. Specific to capital expenditures, for 2024 we anticipate spending to be in the range of $35 million to $40 million. This compares to capital expenditures of $54 million for the year ended December 31, 2023.

We continue to have adequate liquidity in 2024 as we navigate the persistent softness in the commercial environment. As of December 31, 2023, we had liquidity of $289.3 million, consisting of $112.4 million of availability under our revolving credit facility and cash and cash equivalents of $176.9 million. As of December 31, 2023, we had gross debt of approximately $950.1 million.

2023 Compensation Highlights

Key 2023 executive compensation highlights include the following:

| • |  | 2023 Base Salary Increases. For 2023, we provided increases in base salaries (ranging from 3.4% to 4.7%) for our NEOs that generally reflected merit and cost of living adjustments.

| • |  | 2023 Annual Cash Incentive Performance. In the recent past, our STIP awards have been solely based on performance against a target of Adjusted EBITDA, a non-GAAP financial measure. In 2023, the STIP was not solely based on Adjusted EBITDA performance, but also based on performance regarding other financial metrics and non-financial metrics, including Adjusted Free Cash Flow, safety, ESG and diversity training, and community involvement. The Human Resources and Compensation Committee made this change as it desired to align the 2023 STIP program with these other corporate objectives in order to motivate the participants in achieving these corporate objectives. Based on the achievement regarding each of the five metrics, the final-weighted average performance resulted in an achievement of 94% of the target award opportunity. However, the Human Resources and Compensation Committee of the Board thought it was prudent to exercise its discretion as permitted under our STIP and revise the payout downward to 75% of the target award opportunity. The exercise of negative discretion was intended to reflect the efforts of the participants, while also reflecting the ongoing softness in the commercial environment and the challenging business condition that the Company has been experiencing.

| • |  | 2023 Stock Option, RSU and PSU Awards. The Company granted to each of its NEOs stock option, RSU and PSU awards, all of which are ultimately designed to align the interests of our NEOs with those of our stockholders. The RSUs are also designed to help ensure long-term retention of key talent.

Impact of Last Year’s Say-on-Pay Vote

Our stockholders have been supportive of our executive compensation practices. In 2023, our Human Resources and Compensation Committee and Board submitted to our stockholders an advisory vote to approve our NEO compensation, commonly known as a “say-on-pay” vote. Our say-on-pay vote is submitted to our stockholders annually and the next required say-on-pay vote to determine the frequency for future say-on-pay votes will be no later than 2025. We received over 89.7% approval of our say-on-pay proposal at our 2023 annual meeting of stockholders. The Human Resources and Compensation Committee believes the voting results from the 2023 annual meeting of stockholders demonstrate significant support for our NEO compensation program. As a result, the Human Resources and Compensation Committee made no material changes in the structure of our named executive officer compensation program based on the say-on-pay voting results.

Overview of Our 2023 Executive Compensation Program

The design and operation of our NEO compensation program reflect our objectives of driving financial and operational performance that will deliver value and propel growth, while attracting and retaining talented executive leadership, and aligning the interests of our NEOs with those of our stockholders.

The primary elements of our NEO compensation program for 2023 are shown in the following table. The amounts of compensation were determined by the Human Resources and Compensation Committee based on the objectives described below. The Human Resources and Compensation Committee did not solely rely on formulas or survey results, but instead it used its judgment based on its assessment of the Company’s objectives and performance in light of those objectives. The former CEO and the Interim CEO played no role in determining their own respective compensation. Mr. Kessler did, however, make recommendations, in particular with regard to base salary increases, for the compensation of his direct reports for 2023.

The Human Resources and Compensation Committee has engaged Meridian Compensation Partners (“Meridian”) as its independent compensation consultant. In 2023, Meridian did not perform any material work for the Company other than providing executive compensation advice to the Human Resources and Compensation Committee. The Human Resources and Compensation Committee has assessed the independence of Meridian, and has determined Meridian’s work for the Human Resources and Compensation Committee raised no conflicts of interest.

The percentages reflect the amounts of 2023 base salary rate as of the end of the year, targeted 2023 annual cash incentive compensation, and the aggregate grant date fair values of stock options, RSUs and PSUs granted in 2023. The Chief Executive Officer chart reflects compensation amounts for Mr. Kessler.

Peer Group

The Human Resources and Compensation Committee does not use compensation data about other companies as a benchmark on which to base, justify or provide a framework for an executive compensation decision. Rather the Human Resources and Compensation Committee reviews or considers peer group and published survey compensation information to obtain a general understanding of compensation practices of other companies. Every other year, the compensation consultant reviews current and potential peer companies and recommends changes primarily based upon revenue size. The Human Resources and Compensation Committee evaluates such recommendations and will make changes to the peer group, as necessary.

The Human Resources and Compensation Committee, with the assistance of the compensation consultant, undertook a peer group review in late 2022 that was used as a general understanding of compensation practices among our peers when determining our executive compensation in 2023. Our current peer group consists of the 21 companies listed below. Last twelve month revenues as of October 2022 for the peer companies ranged from approximately $806 million to $5.5 billion, with GrafTech ranking at approximately the 20th percentile.

Key Components of Our 2023 Executive Compensation Program

2023 Base Salaries

We pay base salaries to provide a fixed amount of compensation that is not subject to performance-related risk commensurate with the NEOs’ scope of their responsibilities, the length of their experience performing those responsibilities and their performance. Based on these factors, the Human Resources and Compensation Committee reviews base salaries for NEOs at least annually in the first quarter of each year and at other times, as appropriate, in connection with a promotion or other change in responsibility. The Human Resources and Compensation Committee also generally takes into account market data provided by our compensation consultant with respect to comparable positions. Any changes to base salaries typically go into effect on April 1 of each year or in connection with a hiring or a promotion.

In 2023, the Human Resources and Compensation Committee approved increases in base salaries for the NEOs. The increases reflected merit and cost of living adjustments in order to incentivize and help retain such individuals as a component of an appropriate mix of base salary and performance-based compensation. Annual base salary rate amounts that were in effect as of the end of 2022 and 2023 for each of our NEOs are set forth below:

Name |  | 2022 Salary ($) |  |  | % Increase for 2023 |  |  | 2023 Salary ($) |
Timothy K. Flanagan (1) |  |  | 430,000 |  |  |  | 4.7 | % |  |  | 450,000 |
Marcel Kessler |  |  | 750,000 |  |  |  | 4.0 | % |  |  | 780,000 |
Catherine Hedoux-Delgado(1) |  |  | 295,000 |  |  |  | 3.4 | % |  |  | 305,000 |
Jeremy S. Halford(1) |  |  | 541,000 |  |  |  | 3.9 | % |  |  | 562,000 |
Iñigo Perez Ortiz(2) |  |  | 469,892 |  |  |  | 3.9 | % |  |  | 488,218 |
Gina K. Gunning |  |  | 400,000 |  |  |  | 4.0 | % |  |  | 416,000 |

(1) | Amounts do not reflect the monthly stipend Messrs. Flanagan and Halford and Ms. Hedoux-Delgado received ($21,000, $8,000 and $4,000, respectively, beginning on November 15, 2023 in connection with interim roles and additional job responsibilities (the “Stipends”). For 2023, these Stipends totaled $31,500, $12,000 and $6,000, respectively, for Messrs. Flanagan and Halford and Ms. Hedoux-Delgado.

(2) | Mr. Perez received his base salary amounts in 2023 and 2022 in the form of Swiss Francs (“CHF”). The amounts for Mr. Perez are shown in USD using a foreign currency exchange rate of 1.0753 CHF/USD.

Annual Cash Incentive Compensation for 2023 - STIP

The STIP allows us to provide competitive incentives to our NEOs by having a portion of their annual cash compensation be dependent upon annual Company performance and “at risk.” This motivates and rewards our NEOs for the achievement of financial performance measures and other corporate objectives. The STIP generally requires an NEO to be continuously employed with the Company through the payment date in the following year, in order to be entitled to the award, unless the NEO experiences a death or disability or involuntary termination not as a result of detrimental conduct between the last day of the fiscal year and the payment date. An NEO who experiences a retirement during the year or before the payment date shall continue to be eligible to receive an award at a pro-rated amount. We believe these awards not only motivate performance but also encourage retention of our NEOs.

##### Table of Contents

For 2023, the STIP award was based on both financial and non-financial metrics with different target weights for each metric as presented below.

|  | Financial Metrics |  |  | Non-Financial Metrics |  |  |  |
Multiplier Weighting |  | Adjusted EBITDA(1) |  |  | Adjusted Free Cash Flow(1) |  |  | Safety |  |  | ESG & Diversity Training |  |  | Community Involvement |  |  | Total |

Maximum |  |  | 80 | % |  |  | 80 | % |  |  | 20 | % |  |  | 10 | % |  |  | 10 | % |  |  | 200 | %

(1) | Adjusted EBITDA and Adjusted Free Cash Flow are non-GAAP financial measures. See Appendix A to this Proxy Statement for additional information, including how we define these financial measures and prior period reconciliations to the most directly comparable financial measures calculated and presented in accordance with U.S. GAAP.

The safety non-financial metric was centered around total recordable incident rate per 200,000 hours worked. Total recordable incident is a measure of occupational health and safety based on the number of incidents reported against hours worked. The target level of performance for the safety metric was 0.50. The ESG & Diversity training non-financial metric was based on the participation rate of salaried staff in our Company-wide ESG & Diversity training. The target level of performance for that metric was at least 80% participation by our salaried staff. Finally, the community involvement metric was based on the number of community events or engagements held by each of our manufacturing plants, corporate headquarters, Seadrift and Salvador machining shop. The target level of performance for the community involvement metric was at least four community events at each location.

The 2023 STIP target award opportunities for the NEOs, reflected as a percentage of 2023 base salary in effect as of April 1, 2023, were as follows:

Name |  | 2023 Target Award |  |  | Target Award as a Percentage of Base Salary(1) |
Timothy K. Flanagan(2) |  | $ | 385,200 |  |  |  | 80 | %
Marcel Kessler |  | $ | 780,000 |  |  |  | 100 | %
Catherine Hedoux-Delgado(2) |  | $ | 140,175 |  |  |  | 45 | %
Jeremy S. Halford(2) |  | $ | 459,200 |  |  |  | 80 | %
Iñigo Perez Ortiz |  | $ | 388,973 |  |  |  | 75 | %
Gina K. Gunning |  | $ | 270,400 |  |  |  | 65 | %

(1) | The target award as a percentage of base salary for 2023 remained unchanged from the 2022 percentage for each of our NEOs, except for Mr. Flanagan, whose target award as a percentage of base salary was increased from 75% to 80% for merit purposes.

(2) | The target award amounts for each of Mr. Flanagan, Ms. Hedoux-Delgado and Mr. Halford reflect the Stipends they began receiving on November 15, 2023 of $21,000, $4,000 and $8,000, respectively, on a monthly basis.

The STIP award was designed to provide a possible payout ranging from no payout to an aggregate payment of up to two times the target annual incentive, with interpolation in between levels, and payout was dependent upon the level of achievement with respect to each of the five metrics as described above. Based on the achievement of each of the five metrics, the final weighted-average performance resulted in an achievement of 94% of the target award opportunity as more fully described below.

Notwithstanding that the final weighted-average performance resulted in an achievement of 94% of the target award opportunity, the Human Resources and Compensation Committee of the Board thought it was prudent to exercise its negative discretion as permitted under our STIP and revise the payout downward to 75% of the target award opportunity given the ongoing softness in the commercial environment and the desire to reduce costs. Consequently, each of the NEOs earned the following final cash amount as their 2023 STIP award:

Long-Term Incentive Compensation for 2023

We provide long-term incentive compensation to our NEOs. Our long-term incentive program is designed to help retain our NEOs and to incentivize them to make decisions with a long-term view and to motivate and influence behavior on their part that is consistent with maximizing value for the stockholders of the Company in a prudent manner. Outstanding awards have been made under our Equity Plan. Our Equity Plan allows us to grant options and other stock-based awards, including RSUs and PSUs.

In 2023, we granted stock options, RSUs and PSUs to each of our NEOs. These awards are designed to align the interests of our NEOs with those of our stockholders. The RSUs are also designed to help ensure long-term retention of key talent.

For 2023, the target long-term incentive award value for each NEO was determined as a percentage of base salary. The award opportunity percentages of base salary for Messrs. Flanagan, Halford, and Perez and Ms. Gunning were increased from 140% of base salary to 150% of base salary and 215% of base salary to 288% of base salary for Mr. Kessler. The award opportunity percentage of base salary remained unchanged from 2022 to 2023 for Ms. Hedoux-Delgado (70%). The target long-term incentive award value as a percentage of base salary was then allocated to each award type depending on the position of the NEO, with 40% of the target long-term incentive award value being allocated to PSUs, 40% to RSUs and 20% to stock options for each NEO other than Mr. Kessler, whose long-term incentive award value was allocated 50% to PSUs, 25% to RSUs and 25% to stock options, and Ms. Hedoux-Delgado, whose long-term incentive award value was allocated 30% to PSUs, 50% to RSUs and 20% to stock options, in each case. The allocations were then converted into a number of shares for each NEO, using the 20-business day volume weighted-average share price prior to the date of grant of $5.74 for RSUs and PSUs and a Black-Scholes estimate of $3.1647 for stock options.

The long-term incentive award opportunities for Mr. Kessler’s 2023 targeted long-term incentive compensation were as follows:

Name |  | 2023 Base Salary(1) |  |  | x |  |  | Multiple of Base Salary |  |  | = |  |  | 2023 LTIP Value(2) |  |  | = |  |  | No. of Target PSUs Granted (50%) |  |  | No. of RSUs Granted (25%) |  |  | No. of Options Granted (25%) |

The long-term incentive award opportunities for each of the other NEO’s (other than Ms. Hedoux-Delgado) 2023 long-term incentive compensation were as follows:

Restricted Stock Units Granted in 2023

We awarded time-based RSUs to each of our NEOs in February 2023. The RSUs generally vest ratably over three years on each anniversary of the date of grant, subject to acceleration in certain circumstances. As soon as practicable following each vesting date, the NEO receives one share of common stock in respect of each vested RSU. The RSUs accrue dividend equivalents with such dividend equivalents vesting on the same schedule as the shares underlying the RSUs to the extent that dividends are declared by the Board on the common stock of the Company. The RSUs granted in 2023 were as follows:

Name |  | RSUs Granted in 2023 |
Timothy K. Flanagan |  |  | 47,038 |
Marcel Kessler |  |  | 97,997 |
Catherine Hedoux-Delgado |  |  | 18,598 |
Jeremy S. Halford |  |  | 58,746 |
Iñigo Perez Ortiz |  |  | 51,440 |
Gina K. Gunning |  |  | 43,484 |

Stock Options Granted in 2023

We awarded stock options to each of our NEOs in February 2023. The exercise price for stock options is set at the closing stock price on the date of grant, which was $5.60 on February 25, 2023. The stock options generally vest ratably over three years on each anniversary of the date of grant, subject to acceleration in certain circumstances. Stock options remain outstanding for up to ten (10) years from the date of grant, unless exercised or terminated earlier as provided in the award. The stock options granted in 2023 were as follows:

Performance-Based Restricted Stock Units Granted in 2023

We awarded PSUs to each of our NEOs in February 2023. The PSUs are based on our relative total shareholder return achievement, with total shareholder return (measured by stock performance price and any dividends reinvested) for us compared against that for a peer group for each of three measurement periods consisting of 12, 24, and 36 months (with a third of the total PSUs subject to each measurement period), and payout opportunities as follows:

Performance Level |  | Index Percentile Achievement(1) |  | Payout as a % of Target
Maximum |  | 85th |  | 200%
Target |  | 50th |  | 100%
Threshold |  | 25th |  | 50%
Below Threshold |  | Below 25th |  | 0%

(1) | Payouts will be interpolated on a straight-line basis between various performance levels.

Each of the three measurement periods of 12, 24 and 36 months allow the NEO to earn 1/3 of the award at the applicable performance level (from 0% to 200%) during each such period, although none of the earned award vests until the end of three-year performance period. If our absolute total shareholder return is negative during any applicable measurement period, then the portion of the award earned for such measurement period is capped at 100%. The companies that constitute our peer group constitute the comparator group for the PSU award (subject to adjustment as described in the PSU award agreement). Earned PSUs will be entitled to be settled in shares, along with any dividend equivalents accrued on such earned shares.

The target amount of PSUs granted in 2023 were as follows:

Name |  | 2023 PSU Awards (Target) |
Timothy K. Flanagan |  |  | 47,038 |
Marcel Kessler |  |  | 195,993 |
Catherine Hedoux-Delgado |  |  | 11,159 |
Jeremy S. Halford |  |  | 58,746 |
Iñigo Perez Ortiz |  |  | 51,440 |
Gina K. Gunning |  |  | 43,484 |

Other Arrangements, Policies and Practices

Employment Agreements

We do not have employment agreements with our NEOs, other than Mr. Kessler (which is described below following the Summary Compensation Table), but we are a party to offer letters with our other NEOs. See below under the “Potential Payments Upon Termination or Change in Control” section for more information about these arrangements.

Savings Plan and Other Benefits

All of our regular, full-time U.S. employees, including eligible NEOs, may participate in our Savings Plan. Mr. Kessler and Mr. Perez participated in a similar Swiss retirement benefit plan. In 2023, we made a matching contribution to the Savings Plan for each participant who elected to contribute to the Savings Plan. The 2023 matching contribution was 100% of the first 5% of compensation (including base salary and STIP earnings) that a participant contributed. Matching contributions under the Savings Plan are fully vested. In addition to matching contributions, we made employer contributions to the Savings Plan equal to 3% of a participant’s eligible cash-based compensation, including base salary and STIP earnings, up to the applicable limits under tax rules. A participant becomes vested in these employer contributions to the Savings Plan once he or she has completed three years of service. We also made a contribution to the retirement benefit plan in which Mr. Kessler and Mr. Perez participate, as further described below.

Our eligible NEOs may participate in the same medical, life and disability insurance programs and other welfare plans as the rest of our employees, including on substantially similar terms. In addition, we provided Mr. Kessler and Mr. Halford with certain payments directly tied to their prior international assignment in Switzerland, as further described below.

Policies on Transactions in Company Stock, Including Anti-Hedging Provisions

Our Insider Trading Policy imposes limits as to when and how Company employees, including our executive officers and directors, can engage in transactions in our securities and prohibits short sales, put, call or other derivative transactions, or hedging transactions, in each case, with respect to our common stock. See “Corporate Governance - Policies on Transactions in Company Stock, Including Anti-Hedging Provisions” above.

Executive Stock Ownership Guidelines

Effective January 1, 2024, each continuing NEO shall, within five (5) years of the later of January 1, 2024 and becoming a NEO, acquire shares of common stock (or stock equivalents) of the Company having a value in the aggregate equal to the following multiple of the applicable officer’s annual base salary in effect on January 1 (the “NEO Stock Threshold”): (a) CEO (5x annual base salary) and (b) Other NEOs (3x annual base salary).

GrafTech common stock, including shares held jointly or in a trust, and unvested RSUs will count towards the NEO Stock Threshold. Any common stock received upon the vesting of RSUs must be held and may not be sold until the NEO Stock Threshold is met other than vested RSUs withheld to cover taxes. The NEO Stock Threshold will be calculated each year on January 1 and in the event that a NEO who previously met the NEO Stock Threshold no longer does, that NEO will need to acquire more common stock in order to satisfy the NEO Stock Threshold by the following January.

Clawback Policy and Recoupment Provisions in Equity Plan Award Agreements

In accordance with new SEC regulations and NYSE listing standards, the Board approved a new Compensation Clawback Policy that applies to certain incentive-based compensation received by our executive officers, including our NEOs, after October 2, 2023. The new Compensation Clawback Policy generally provides for the reasonably prompt recovery (or clawback) of certain excess incentive-based compensation received during an applicable three-year recovery period by current or former executive officers in the event we are required to prepare an accounting restatement due to the material noncompliance with any financial reporting requirement under the securities laws. Triggering events include accounting restatements to correct an error in previously issued financial statements that is material to such previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Excess incentive-based compensation for these purposes generally means the amount of incentive-based compensation received (on or after October 2, 2023) by such executive officer that exceeds the amount of incentive-based compensation that would have been received by such executive officer had it been determined based on the restated amounts, without regard to any taxes paid. The Compensation Clawback Policy does not condition the clawback on the fault of the executive officer. Incentive-based compensation potentially subject to recovery under the mandatory accounting restatement provisions of the Compensation Clawback Policy is generally limited to any compensation granted, earned or vested based wholly or in part on the attainment of one or more financial reporting measures.

In general, we may utilize a broad range of recoupment methods under the Compensation Clawback Policy for mandatory accounting restatement clawbacks. However, we are not required to clawback amounts in limited circumstances where the Compensation Committee has made a determination that recovery would be impracticable and (1) we have already attempted to recover such amounts but the direct expense paid to a third party in an effort to enforce the Compensation Clawback Policy would exceed the amount to be recovered, (2) the recovery of amounts would violate applicable home country law, or (3) the recovery would likely cause the non-compliance of a tax-qualified retirement plan under the Internal Revenue Code of 1986, as amended, and applicable regulations. Operation of the mandatory accounting restatement provisions of the Compensation Clawback Policy is subject to a brief phase-in process during the first few years after its effectiveness. We may not indemnify any such executive officer against the loss of such recovered compensation in the event of a mandatory accounting restatement.

Further, the terms of our equity-based awards (1) entitle, to the extent permitted or required by applicable law, Company policy (including the new Compensation Clawback Policy) and/or the requirements of an exchange on which our shares are listed for trading, the Company to recoup compensation of any kind paid by the Company at any time under our Equity Plan and (2) provide for reduction, cancellation, forfeiture or recoupment of an award if the participant violates material GrafTech policies, breaches any applicable restrictive covenant, or engages in Detrimental Conduct. “Detrimental Conduct” means activities which have been, are or would reasonably be expected to be detrimental to the interests of the Company, as determined in the sole and good faith judgment of the Human Resources and Compensation Committee. Such activities would include gross neglect or willful and continuing refusal by the Participant to substantially perform his or her duties or responsibilities for or owed to the Company, unlawful conduct under securities, antitrust, tax or other laws, improper disclosure or use of confidential or proprietary information or trade secrets, competition with or improper taking of a corporate opportunity of any business of the Company, failure to cooperate in any investigation or legal proceeding, and misappropriation of property.

Compensation Committee Report

The Human Resources and Compensation Committee of the Company’s Board of Directors has reviewed and discussed the CD&A with the Company’s management. Based on this review and its discussions with management, the Human Resources and Compensation Committee recommended to the Company’s Board of Directors that the CD&A be included in this Proxy Statement for the Annual Meeting and incorporated by reference into the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

(1) | These amounts reflect the target and maximum annual cash incentive compensation amounts that could have been earned with respect to 2023 based upon the achievement of annual performance goals under our STIP. The amounts of annual cash incentive compensation earned with respect to 2023 by our NEOs were determined in February 2024 and paid in March 2024. The amounts paid are included in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. Mr. Flanagan’s and Ms. Hedoux-Delgado’s target and maximum opportunities reflect the Stipends they received beginning on November 15, 2023 in connection with each of their interim roles. Mr. Halford’s target and maximum opportunities reflect the Stipend he received beginning on November 15, 2023 in connection with his work on key strategic initiatives, including leading efforts in connection with the active investigation into the use of the Company’s assets to supply the growing electric vehicle battery market, along with his current duties as Executive Vice President, Chief Operating Officer.

(2) | These amounts reflect the threshold, target and maximum number of PSUs granted on February 25, 2023 under our Equity Plan. The PSUs generally vest on December 31, 2025 to the extent that the participant’s employment continues through such date and the performance goals for the PSUs are achieved, once determined and certified by the Human Resources and Compensation Committee.

(3) | These amounts reflect the number of RSUs granted on February 25, 2023 under our Equity Plan. These RSUs generally vest ratably over three years on each anniversary of the date of grant.

(4) | These amounts reflect the number of stock options granted on February 25, 2023 under our Equity Plan. These stock options generally vest ratably over three years on each anniversary of the date of grant and have a term of ten (10) years so that they expire on February 25, 2033.

(5) | The value of the PSUs is equal to the aggregate grant date fair value computed in accordance with stock-based accounting rules FASB ASC Topic 718, Compensation – Stock Compensation. The values included in the column assume a target level of performance for the market condition and were calculated using a Monte-Carlo Simulation. The value of the RSUs is equal to the aggregate grant date fair value computed in accordance with stock-based accounting rules (FASB ASC Topic 718, Compensation – Stock Compensation). This valuation method values the award by multiplying the closing market price of our shares of stock on the grant date as reported on the NYSE ($5.60) by the number of RSUs reported. The value of stock options is equal to the aggregate grant date fair value computed in accordance with stock-based accounting rules (FASB ASC Topic 718, Compensation – Stock Compensation). The values were calculated using a Black-Scholes option pricing model. The assumptions used in this model are as described in Note 3 to the Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Narrative Information Regarding the 2023 Summary Compensation Table and 2023 Grants of Plan-Based Awards Table

The description that follows summarizes the terms and conditions of our employment agreement with Mr. Kessler. We do not maintain employment agreements with any of our other NEOs, but we are a party to offer letters with our other NEOs, some of which provide for severance benefits. This description also summarizes the terms of and the programs under which the compensation reflected in the tables for our NEOs was awarded. Additional information is provided in the “Compensation Discussion and Analysis” and “Potential Payments upon Termination or Change in Control” sections of this Proxy Statement.

Employment Agreements

We have an employment agreement with Marcel Kessler, our former Chief Executive Officer and President, which was entered into in June 2022, became effective July 1, 2022, and was amended and restated June 13, 2023 (the “Kessler Agreement”). Mr. Kessler voluntarily resigned from the Company as Chief Executive Officer and President effective November 15, 2023, but the Kessler Agreement remains in effect for certain purposes as it contains customary non-competition, non-disparagement and non-solicitation provisions. The Kessler Agreement established his base salary rate of $780,000 per year and provided that his base salary will be reviewed for an increase at least annually by the Human Resources and Compensation Committee. Under the Kessler Agreement, Mr. Kessler was eligible to participate in our STIP and was eligible to receive an award with a target annual incentive opportunity equal to 100% of his annual base salary and a maximum annual incentive opportunity equal to 200% of his target opportunity based on performance metric(s) established by the Human Resources and Compensation Committee. Mr. Kessler was also eligible to receive certain perquisites under the Kessler Agreement, including an automobile allowance, as well as reimbursement for reasonable financial and tax counseling services; provided that the sum total amount of the automobile allowance and reimbursement for reasonable financial and tax counsel services did not exceed $25,000 per year. In addition, while serving in Switzerland, Mr. Kessler was to receive an annual housing allowance in the aggregate amount equal to 50,000 CHF. Under the Kessler Agreement, Mr. Kessler is also provided tax equalization in order to eliminate any tax inequities as a result of working in Switzerland.

Salary

The salary amounts disclosed in the 2023 Summary Compensation Table are the amounts of base salary earned by our NEOs during the indicated year and for Messrs. Flanagan and Halford and Ms. Hedoux-Delgado also include the Stipends they each began receiving on November 15, 2023. For 2023, salaries earned by our NEOs accounted for the following percentages of their total compensation set forth in the table: Mr. Flanagan (31.0%), Mr. Kessler (20.7%), Ms. Hedoux-Delgado (46.2%), Mr. Halford (28.5%), Mr. Perez (31.4%), and Ms. Gunning (31.0%).

Short-Term Incentive Awards and Bonuses

The amounts reported in the Non-Equity Incentive Plan Compensation column of the 2023 Summary Compensation Table represent aggregate final payouts of annual cash incentive awards for 2023, which were tied to the achievement of performance measures and target award opportunities established by March of 2023. For 2023, the target cash incentive award opportunities were based on several financial and non-financial metrics, including Adjusted EBITDA, Adjusted Free Cash Flow, Safety, ESG & Diversity Training and Community Involvement. Payouts in 2023 could range from no payout up to a maximum of 200% of the target award, and specific target and maximum levels of performance and related payout scales were established for the awards. Because there was no guaranteed portion of the 2023 STIP award, there are no amounts reflected in the Bonus column for 2023. For additional detail regarding our cash incentive award program and the 2023 cash incentive awards, see the “Compensation Discussion and Analysis” section above.

Performance Stock Unit Awards

The Company made PSU grants to each of our NEOs in 2023. The PSUs will be earned based on the achievement of a performance goal (market condition) of relative total shareholder return, measured by stock performance price and any dividends reinvested, compared against a peer group, over a three-year period with measurement periods after 12-, 24-, and 36-months, and the NEO’s continued employment through the entire three-year period. The three measurement periods of 12-, 24- and 36-months allow an NEO to earn 1/3 of the total award at the performance level achieved at the end of each such period, although the award does not vest and payout until the end of the three-year performance period. If absolute return is negative during a measurement period, then the award is capped at 100% for the respective

measurement period. Payouts could range from no payout up to a maximum of 200% of the target award, and specific target and maximum levels of performance and related payout scales were established for the awards. Each PSU has an associated dividend equivalent right pursuant to which the holder is entitled to receive any ordinary cash dividends that are paid on a share of our common stock for dividend record dates occurring after the grant date and prior to the settlement of the PSUs. These dividend equivalents are deemed reinvested in the form of additional PSUs, which will vest at the same time and schedule as the PSUs generally. The award agreements for the PSUs include vesting provisions in the event of the NEO’s death or disability, termination without cause, or retirement that occurs before the end of the three-year performance period. For additional detail regarding the grants of PSUs made in 2023 to each of our NEOs, see the “Compensation Discussion and Analysis” section above.

Restricted Stock Unit Awards

The Company made time-based RSU grants to each of our NEOs in 2021, 2022 and 2023, other than Mr. Flanagan and Mr. Kessler in 2021. Each RSU includes a dividend equivalent right pursuant to which the holder is entitled to receive any ordinary cash dividends to the extent that dividends are paid on a share of our common stock for dividend record dates occurring after the grant date and prior to the settlement of the RSUs. These dividend equivalents are deemed reinvested in the form of additional RSUs. Unless accelerated earlier pursuant to the terms of the applicable award agreement, the RSUs granted in 2021 and 2022 vest ratably over five years on each anniversary of the date of grant while the RSUs granted in 2023 vest ratably over three years on each anniversary of the date of grant. As soon as practicable following the applicable vesting date, the Company will deliver one share of common stock to the NEO in respect of each vested RSU. Beginning in 2023, the award agreements granting RSUs include accelerated vesting provisions in the event of the NEO’s death or disability, termination without cause, or retirement that occurs before the end of the three-year vesting period. For additional detail regarding the grants of RSUs made in 2023 to each of our NEOs, see the “Compensation Discussion and Analysis” section above.

Option Awards

The Company awarded each of our NEOs options in 2021, 2022 and 2023, other than Mr. Flanagan and Mr. Kessler in 2021. Unless accelerated earlier pursuant to the terms of the applicable award agreement, the options granted in 2021 and 2022 vest in five equal annual installments on the anniversary of the grant date, while the options granted in 2023 vest in three equal annual installments on the anniversary of the grant date. The options expire on the ten (10) year anniversary of the grant date, unless terminated earlier pursuant to the terms of the applicable award agreement. Beginning in 2023, the award agreements granting stock options include accelerated vesting provisions in the event of the NEO’s death or disability, termination without cause, or retirement that occurs before the end of the three-year vesting period. For additional detail regarding the grants of stock options made in 2023 to each of our NEOs, see the “Compensation Discussion and Analysis” section above.

(5) | The market value for the RSUs and PSUs is calculated by multiplying the number of RSUs and PSUs, as applicable, that have not vested by the closing market price of our common stock ($2.19) as reported on the NYSE as of the close of business on December 29, 2023 (the last trading day prior to our December 31, 2023 fiscal year-end).

(6) | PSUs generally vest on December 31, 2025 to the extent that the participant’s employment continues through such date and the performance goals for the PSUs are achieved, once determined and certified by the Human Resources and Compensation Committee after the end of the final measurement period. The PSUs accrue dividend equivalents that are reinvested in the form of additional PSUs. The additional PSUs are reflected in this number. Amounts reflect the threshold level of performance.

Material Features of our Compensation Deferral Plan

The GrafTech Compensation Deferral Plan (the “CDP”) is a non-qualified (unfunded) deferred compensation plan that allows a participant, including our NEOs, to make a pre-tax deferral of base salary and variable compensation, allocate it to various financial growth options, and have it paid to the participant in the future. The participant may defer up to 50% of the participant’s base salary in increments of 1% and up to 85% of the participant’s variable compensation, also in increments of 1%. A minimum combined annual deferral of $1,000 is required.

The participant may choose to have the participant’s deferral account accrue earnings as if held in any of the hypothetical investment options offered under the CDP (“Financial Deferral Options”), which selection may vary from time to time. The participant’s deferrals will not actually be invested in these funds but will be valued as if they were. A deferral allocated to the Financial Deferral Options will track the value (both up and down) of the particular option the participant selects.

Generally, distributions of the participant’s account will be made at retirement, death, disability, or termination of the participant’s employment (if the participant terminates employment before age 50, no distribution will be made until the participant is 50). Subject to certain limitations, the CDP also permits the participant to defer payment to a specified date in the future.

2023 Potential Payments Upon Termination or Change in Control

We have set forth below information regarding payments that would be made to our NEOs upon the occurrence of certain termination and/or change in control events, along with post-employment restrictive covenant obligations. Except for Mr. Kessler, the table below sets forth the potential estimated payments to our NEOs, assuming for this purpose that employment had been terminated and/or a change in control of the Company had occurred in each case on December 29, 2023 and that the price for our common stock was $2.19 based on the closing price of a share of our common stock on December 29, 2023 (the last trading day prior to our December 31, 2023 fiscal year-end) as reported on the NYSE. Mr. Kessler voluntarily resigned from the Company as Chief Executive Officer and President effective November 15, 2023 and terminated as an employee on December 31, 2023 (the information provided below for him applies only to such voluntary resignation).

Equity Awards

In May 2021, the Company experienced a Change in Control under most of the equity awards granted under our Equity Plan prior to such date when Brookfield and affiliates thereof ceased to own stock of our Company that constituted at least thirty percent (30%) or thirty-five percent (35%), as applicable, of the total fair market value or total voting power of the stock of the Company. Accordingly, any equity awards that were granted to our NEOs under the Equity Plan prior to 2022 have vested as of December 29, 2023.

Form of Stock Option Grant Agreement (2022 Version) and Form of Restricted Stock Unit Agreement (2022 Version)

Beginning in 2022, each of the Form of Stock Option Grant Agreement and Form of Restricted Stock Unit Agreement used to grant each of our NEO’s awards under our Equity Plan contain double-trigger vesting of long-term equity incentive awards upon a change in control. That is, in the event of a Change in Control (as defined under each award agreement), if an NEO does not receive a Replacement Award (as defined under each award agreement), or if after receiving a Replacement Award, the NEO experiences a termination of employment with the Company (or any of its successors) by reason of a termination without Cause (as defined under each award agreement) or by the NEO for Good Reason (as defined under each award agreement), in each case, within a period of two years after the Change in Control and during the remaining vesting period for the Replacement Award, any then-outstanding RSUs will become nonforfeitable immediately, any then-outstanding unvested options will become fully vested and exercisable, or the Replacement Award shall become nonforfeitable and payable with respect to the time-based restricted stock units covered by such Replacement Award upon such termination and the Replacement Award shall become nonforfeitable and exercisable at any time prior to the tenth anniversary of the grant date of the options upon such termination.

As of December 29, 2023, the stock options granted to each of the NEOs in 2022 were underwater (i.e., the exercise price of such options exceeded the price of the Company’s common stock) and therefore are not accounted for with value in the table above.

Form of Stock Option Grant Agreement (2023 Version), Form of Restricted Stock Unit Agreement (2023 Version) and Form of Performance Stock Unit Agreement (2023 Version)

Beginning in 2023, in addition to the change in control treatment described immediately above, each of the Form of Stock Option Grant Agreement, Form of Restricted Stock Unit Agreement and Form of Performance Stock Unit Agreement contain accelerated vesting provisions in the event of the NEO’s death or disability, termination without cause, or retirement that occurs prior to the end of the applicable vesting period for each award. As of December 29, 2023, the stock options granted to each of the NEOs were underwater and therefore are not accounted for in the table above. In addition, as a result of the actual performance of the PSUs through December 29, 2023, none of the PSUs are accounted for in the table above, except for the Change in Control (assuming no Replacement Award) triggering event.

##### Table of Contents

Death or Disability

RSUs – If the NEO’s employment is terminated by the NEO due to the NEO’s death or Disability (as defined under the award agreement), any RSUs that remain unvested as of the date of such termination will immediately vest in full.

Options – If the NEO’s employment is terminated by the NEO due to the NEO’s death or Disability, (as defined under the award agreement), any options that remain unvested as of the date of such termination will immediately vest in full on such date of termination and all vested Options will be exercisable until the tenth (10th) anniversary of the grant date.

PSUs – If the NEO dies or becomes Disabled (as defined under the award agreement) prior to the end of the vesting period during the NEO’s employment, the NEO will vest in the number of PSUs in which the NEO would have vested if the NEO remained in continuous employment from the grant date until the end of the vesting period or the occurrence of a change in control to the extent a replacement award is not provided, whichever occurs first.

Termination without Cause

RSUs – If the NEO’s employment is terminated by the Company as the result of a termination without Cause (as defined under the award agreement) that occurs prior to the last vesting date, to the extent any RSUs remain unvested as of the date of such termination, the NEO will immediately vest in the RSUs on a pro-rata basis in an amount equal to the difference (rounded to the nearest whole RSU) between (i) the product of (A) the total number of RSUs subject to the agreement, multiplied by (B) a fraction (in no case greater than 1), the numerator of which is the number of calendar days from the grant date through and including the date of such termination, and the denominator of which is the number of days from the grant date through and including the third anniversary of the grant date, minus (ii) the total number of RSUs that have already vested under the agreement prior to the date of such termination.

Options – If the NEO’s employment is terminated by the Company as the result of a termination without cause (as defined under the award agreement) that occurs prior to the last vesting date, to the extent any options remain unvested as of the date of such termination, on the date of such termination, the NEO will immediately vest in the Options on a pro-rata basis in an amount equal to the difference (rounded to the nearest whole option) between (i) the product of (A) the total number of options subject to the agreement, multiplied by (B) a fraction (in no case greater than 1), the numerator of which is the number of calendar days from the grant date through and including the date of such termination, and the denominator of which is the number of days from the grant date through and including the third anniversary of the grant date, minus (ii) the total number of options that have already vested under the agreement prior to the date of such termination. Any vested options (whether or not they vested on or prior to the NEO’s termination without cause) will be exercisable until the earlier of (A) the first (1st) anniversary of the date of the participant’s termination without cause and (B) the tenth (10th) anniversary of the grant date.

PSUs – If the NEO’s employment is terminated by the Company as the result of a termination without Cause (as defined under the agreement) that occurs prior to the end of the vesting period during the NEO’s employment, the NEO will vest in the PSUs on a pro-rata basis in an amount equal to the product of (A) the number of PSUs in which the NEO would have vested if the NEO had remained in continuous employment from the grant date until the vesting date or the occurrence of a change in control to the extent a replacement award is not provided, whichever occurs first, multiplied by (B) a fraction, the numerator of which is the total number of calendar days from the grant date through the date of such termination and the denominator of which is 1,096.

Retirement

RSUs – If the NEO’s employment is terminated by the NEO as a result of the NEO’s Retirement (as defined in the award agreement) that occurs after the grant date, to the extent any RSUs remain unvested as of the date of the NEO’s retirement, the vesting of the RSUs shall accelerate on a pro-rata basis on the date of the NEO’s retirement.

##### Table of Contents

Options – If the NEO’s employment is terminated by the NEO as a result of the NEO’s Retirement (as defined in the award agreement) that occurs after the grant date, to the extent any options remain unvested as of the date of the NEO’s retirement, the vesting of the options will accelerate on a pro-rata basis on the date of the NEO’s retirement. Any vested options (whether or not they vested on or prior to the NEO’s retirement) will be exercisable until the earlier of (i) the fifth (5th) anniversary of the date of the NEO’s retirement and (ii) the tenth (10th) anniversary of the grant date.

PSUs – If the NEO’s employment is terminated by the NEO as the result of Retirement (as defined in the award agreement) that occurs prior to the end of the vesting period and on or after the grant date, the NEO will vest in the PSUs on a pro-rata basis in an amount equal to the product of (A) the number of PSUs in which the NEO would have vested if the NEO had remained in continuous employment from the grant date until the end of the vesting period or the occurrence of a change in control to the extent a replacement award is not provided, whichever occurs first, multiplied by (B) a fraction, the numerator of which is the total number of calendar days from January 1, 2023 through the date of Retirement and the denominator of which is 1,096.

Under the 2023 option, RSU and PSU award agreements, “Retirement” means the termination of the NEO’s employment after the NEO has reached (i) at least age 60 with at least five years of employment or (ii) at least age 55 with at least ten years of employment and the NEO has provided GrafTech with at least six (6) months’ advance written notice of the participant’s intent to retire from employment, unless such notice requirement has been waived by the CEO or the Human Resources and Compensation Committee (either in its sole discretion).

Change in Control

PSUs – If at any time before the end of the vesting period or forfeiture of the PSUs, and during the NEO’s employment, a Change in Control (as defined under the agreement) occurs, then the PSUs will vest (except to the extent that a replacement award is provided to the NEO) based on actual performance through the most recently practicable date prior to the Change in Control for which achievement of the performance goals for each measurement period can reasonably be determined; provided, however, that if the number of vested PSUs is less than the target number of PSUs evidenced by the award agreement, then the NEO will vest in the target amount of PSUs.

If, after receiving a replacement award, the NEO experiences a termination of employment with the Company (or any of its successors) by reason of a termination by the Company without cause or by the NEO for good reason, in each case within a period of two years after the Change in Control and during the remaining vesting period for the replacement award, 100% of the replacement award will become vested with respect to the PSUs covered by such replacement award upon such termination.

Short-Term Incentive Plan Awards

Under the terms of the STIP, if prior to the date the annual incentive amount is payable, an NEO’s employment with the Company is terminated voluntarily (other than due to Retirement (as defined in the STIP)) or is terminated involuntarily due to Detrimental Conduct (as defined in the STIP), then such NEO will not be entitled to any annual incentive amount for the plan year. However, in the event of the NEO’s death or Disability (as defined in the STIP), whether long-term or short-term, or involuntary termination by the Company not as a result of Detrimental Conduct, an NEO who is on the payroll as an active employee as of the last day of a plan year will be eligible to receive an award for such plan year.

An NEO who experiences a Retirement during the plan year (or after but before the date the award is payable) will continue to be eligible to receive an award for such plan year. A “Retirement” under the STIP means an NEO’s voluntary termination of employment or service to the Company and its subsidiaries (i) upon or after attaining age 62, and (ii) only if the Human Resources and Compensation Committee in its sole and exclusive discretion (and first considering the recommendation of the Company’s Chief Executive Officer) consents to such voluntary termination of employment constituting a “Retirement” for purposes of prorated award treatment under the STIP; provided, however, that any prorated award received by an NEO under STIP due to Retirement will be subject to recoupment by the Company in its discretion if the NEO obtains reasonably material subsequent employment with any other for-profit company or similar entity. None of our NEOs were eligible for “Retirement” under our STIP as of December 31, 2023.

##### Table of Contents

Except to the extent that a replacement award is provided to the participant to continue, replace or assume the incentive award, in the event of a Change of Control (as defined in the STIP) during the plan year, then, immediately prior to the Change in Control, the participant’s award shall be deemed to have been earned and shall be authorized at the target award level for the plan year, or in the event of a Change in Control after the plan year but before payment of the award, then, immediately prior to the Change in Control, the participant’s award shall be deemed to have been earned and shall be authorized at the greater of (a) the target award level for the plan year or (b) the actual performance for the plan year.

2022 Retention Bonus Agreement

If the NEO’s employment with the Company and its subsidiaries is terminated prior to the end of May 31, 2024, or if the NEO at any point is no longer in good standing with the Company during the retention period, the NEO will not earn any portion of the of the retention bonus (it will be forfeited). However, if the NEO’s worksite closes, the NEO’s role is eliminated, or the NEO’s employment with the Company and its subsidiaries is terminated without cause during the retention period (in all three cases determined on a reasonable basis in the sole discretion of the Company) when the retention bonus has not otherwise been forfeited, then the NEO will earn a pro-rated payout of the retention bonus based on the number of days the NEO was employed by the Company or any of its subsidiaries during such retention period.

If a Change in Control (as defined under the agreement) occurs before the NEO otherwise earns (or forfeits) the retention bonus (but except to the extent that a replacement bonus is provided to the NEO to continue, substitute for, replace or assume the retention bonus opportunity), the NEO will be deemed to have earned the retention bonus in its entirety as of immediately prior to the Change in Control (even if the NEO’s employment with the Company and its subsidiaries is terminated on the date of such Change in Control).

Flanagan Severance Arrangement

Under the terms of his offer letter, in the event that Mr. Flanagan is terminated by the Company without “Cause” (as defined in his offer letter), the Company will pay Mr. Flanagan his base salary for one year, subject to his execution of a release agreement in favor of the Company. The terms of the offer letter further provide that Mr. Flanagan is subject to non-compete and non-solicitation covenants during his employment and for a period of two years following termination of his employment, as well as a perpetual non-disparagement covenant.

Kessler Agreement

As described above, Mr. Kessler and the Company entered into the Kessler Agreement in connection with his employment as Chief Executive Officer and President in 2022. The Kessler Agreement provides that Mr. Kessler is subject to customary restrictive covenants, including non-competition, non-solicitation, and non-disparagement, each of which continue for one year following Mr. Kessler’s voluntary resignation.

Halford Severance Arrangement

Perez Benefits Addendum

Under the terms of his benefits addendum, in the event that Mr. Perez is terminated by the Company without cause (and other than as a result of death or disability), then, Mr. Perez will be eligible to receive 12 months of his base salary at the rate in effect immediately prior to such termination of employment, payable in substantially equal installments in accordance with the Company’s payroll practices in effect from time to time, commencing on the 60th day following the date of such termination and ending on the last payroll date of such 12-month period (the first such installment payment will include all amounts that would have been paid to him in accordance with the Company’s payroll practices if such payments had begun on the date of such termination). This benefit will be paid only if, within the period between the 32nd and 60th day after the end of Mr. Perez’s employment, Mr. Perez signs and returns to the Company a general release of claims against the Company and all related persons and entities in the form reasonably requested by the Company.

Under the terms of her offer letter, in the event that Ms. Gunning is terminated by the Company for a reason other than for cause, the Company will pay Ms. Gunning her base salary for one year, subject to her execution of a release agreement in favor of the Company.

CEO Pay Ratio

SEC rules require us to disclose the median of the annual total compensation of all our employees (except our Chief Executive Officer) (the “PEO” for pay ratio purposes), the annual total compensation of the Chief Executive Officer and the ratio of these two amounts for our last completed fiscal year.

Consistent with applicable SEC rules, we may identify our median employee for purposes of providing pay ratio disclosure once every three years and calculate and disclose total compensation for that employee each year; provided that, during the last completed fiscal year, there has been no change in the employee population or employee compensation arrangements that we reasonably believe would result in a significant change to the prior year’s CEO pay ratio disclosure. We reviewed the changes in our employee population and employee compensatory arrangements and determined there has been no change in our employee population or employee compensatory arrangements that would significantly impact the 2023 CEO pay ratio disclosure and ultimately require us to identify a new median employee for 2023. As a result, we used the same median employee for the 2023 CEO pay ratio as we did for the 2022 and 2021 CEO pay ratio disclosure.

To identify the employee with annual total compensation at the median of all of our employees for fiscal year 2021 (the “Median Employee”), we measured the gross taxable income in each applicable jurisdiction for the 12-month period ended December 31, 2021 for 1,352 employees, representing all full-time, part-time, seasonal and temporary employees (other than our PEO) as of December 31, 2021. This number does not include any independent contractors, or leased workers, as permitted by the applicable SEC rules. This number includes non-U.S. employees. A portion of our employee workforce (full-time and part-time) identified above worked for less than the full fiscal year due to commencing employment after January 1, 2021. In determining the Median Employee, we annualized the gross taxable income for such individuals based on reasonable assumptions and estimates relating to our employee compensation program, including incentive compensation programs.

For purposes of this pay ratio disclosure only, the PEO’s compensation was $1,884,791. Consistent with applicable SEC rules, since Mr. Kessler resigned as our Chief Executive Officer and President effective November 15, 2023, we are permitted to calculate the annual total compensation for our PEO by calculating the compensation provided to each person who served as PEO during the year for the time he served as PEO and combine those figures or annualize the compensation of the person who served as PEO on the anniversary in 2023 of the date selected for identifying the median employee. We chose to annualize Mr. Flanagan’s Salary and Non-Equity Incentive Plan Compensation amounts as disclosed in the Summary Compensation Table, particularly to reflect his stipend as if he earned it the entire year. The effect of this annualization increases his salary by the annualized amount and also increases his target opportunity for his STIP by said amount.

The total annual compensation of our Median Employee was $44,276, which was calculated by totaling, for our Median Employee, all applicable elements of compensation for the 2023 fiscal year in accordance with Item 402(c)(2)(x) of Regulation S-K. The median employee’s annual total compensation was paid in euros (“EUR”) and has been converted to U.S. dollars using a foreign currency exchange rate of 1.1038 EUR/USD as reported in The Wall Street Journal on close of business as of December 29, 2023.

For 2023, the ratio of the annual total compensation of Mr. Flanagan, our Interim Chief Executive Officer and President, to the annual total compensation of our Median Employee was approximately 43 to 1. We note that, due to our permitted use of reasonable estimates and assumptions in preparing this pay ratio disclosure, the disclosure may involve a degree of imprecision, and this pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions described below.

Questions & Answers

Q. | Why did I receive these proxy materials?

A. | You received these materials because you were a stockholder as of the close of business on March 13, 2024, the Record Date fixed by the Board, and are therefore entitled to receive notice of the Annual Meeting and to vote on matters presented at the Annual Meeting, which will be held on May 9, 2024.

Q. | When and where is the Annual Meeting being held?

A. | The Annual Meeting will be held on May 9, 2024 at 8:00 a.m. Eastern Time. Our Annual Meeting will be a completely virtual meeting of stockholders, which will be conducted exclusively by audio webcast.

After you have registered, you will be able to participate in the Annual Meeting by visiting [•] and entering the same 16-digit control number you used to pre-register and as shown in your confirmation e-mail. Beneficial stockholders who do not have a 16-digit control number should follow the instructions provided on the voting instruction form provided by your broker, bank, or other nominee. In addition to registering for the meeting, beneficial holders that wish to vote at the meeting must obtain a legal proxy from their bank, broker, or other nominee prior to the meeting. You will need to have an electronic image (such as a pdf file or scan) of the legal proxy with you if you are voting at the meeting.

Q. | Who is entitled to vote at the Annual Meeting?

A. | Holders of GrafTech’s common stock at the close of business on March 13, 2024, the Record Date fixed by the Board, may vote at the Annual Meeting.

Q. | How many votes may I cast?

A: | Each share of common stock is entitled to one vote with respect to each of the matters submitted for vote. On March 13, 2024, there were [256,831,870] shares of common stock outstanding and entitled to vote.

Q. | What constitutes a quorum for the Annual Meeting?

A. | The presence, in person or by proxy, at the commencement of the Annual Meeting, of the holders of a majority of the shares of common stock issued and outstanding as of close of business on March 13, 2024 constitutes a quorum for the transaction of business at the meeting. We will count abstentions as present for purposes of determining the presence or absence of a quorum at the Annual Meeting. “Broker non-votes” (shares held by a broker or nominee that does not have discretionary authority to vote on a particular matter and has not received voting instructions from its client on that matter) will not be counted for the purpose of determining whether a quorum is present and will not be considered votes cast on the proposals to be considered at the Annual Meeting. Virtual attendance at our Annual Meeting constitutes presence in person for purposes of the vote required under our By-Laws.

Q. | What items will be voted on at the Annual Meeting, and what is the required vote to approve each item?

A. | All stockholders are entitled to vote on the following proposals:

68 / GrafTech International Ltd. |2024 Proxy Statement |  |

##### Table of Contents

| • |  | Proposal 1—To elect two directors for a three-year term or until their successors are elected and qualified;

| • |  | Proposal 2—To ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2024;

| • |  | Proposal 3—To approve, on an advisory basis, our named executive officer compensation; and

| • |  | To transact such other business as may properly come before the meeting or any adjournments or postponements thereof.

Assuming the Undavia Nominee is in fact properly presented for election at the Annual Meeting and such nomination has not been withdrawn by the Undavia Group, the election of directors will be considered a contested election and, as provided under Article III, Section 2 of GrafTech’s By-laws, directors will be elected on a plurality basis. This means that the two (2) director nominees receiving the greatest number of votes cast “FOR” their election will be elected. Abstentions and any broker non-votes will not be counted as votes cast and will result in the applicable nominee(s) receiving fewer votes cast “FOR” such nominee(s). In the event that the Undavia Group withdraws its nominee, abandons its solicitation or fails to comply with the universal proxy rules, the election will be considered uncontested, any votes cast in favor of any Undavia Group Nominee, as applicable, will be disregarded and not be counted, whether such vote is provided on the Company’s WHITE proxy card or the Undavia Group’s [•] proxy card, and directors will be elected on a majority basis of the remaining votes.

Proposal 2 requires an affirmative majority of the voting power of the shares present in person or by proxy at the meeting and entitled to vote thereon--i.e., the number of “for” votes must exceed the combination of the total of “against” votes and abstentions. Under NYSE rules, the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ended December 31, 2024 is normally considered “routine” and would be the only proposal on this year’s Annual Meeting agenda with respect to which your broker could vote your shares absent your instructions. As a result, broker non-votes are typically not expected on Proposal 2. However, to the extent your broker provides you with the Undavia Group’s proxy materials it will not have discretion to vote on “routine matters,” including Proposal 2. In such circumstances, if you do not instruct your broker on how to vote your shares regarding Proposal 2, then your shares may not be voted on this matter. We urge you to instruct your broker about how you wish your shares to be voted using the WHITE voting instruction form.

Proposal 3 requires an affirmative majority of the voting power of the shares present in person or by proxy at the meeting and entitled to vote thereon—i.e., the number of “for” votes must exceed the combined total of “against” votes and abstentions (broker non-votes will have no effect on the outcome of Proposal 3.

Although the advisory vote on named executive officer compensation is non-binding, our Human Resources and Compensation Committee expects to consider and take into account the voting results when making future determinations.

Q. | Are there other items to be voted on at the Annual Meeting?

A. | We do not know of any other matters that may come before the Annual Meeting. If any other matters are properly presented at the Annual Meeting, your proxy authorizes the individuals named as proxies to vote, or otherwise act, in accordance with their best judgment.

Q. | Why have I received different color proxy cards?

A. | As discussed above, the Undavia Group has notified us that it intends to nominate a candidate for election as directors at the Annual Meeting. The Board has provided you with the enclosed WHITE proxy card. The Undavia Group may send you a [•] proxy card. The Board recommends using the enclosed WHITE proxy card to vote “FOR” only the two nominees proposed by the Board for election as directors. The Board also recommends that you DISREGARD and DISCARD [•] proxy cards.

Your shares may be owned through more than one brokerage or other share ownership account. In order to vote all of the shares that you own, you must use each WHITE proxy card you receive in order to vote with respect to each account by Internet, by telephone or by marking, signing, dating and returning the WHITE proxy card in the postage pre-paid envelope provided.

If the Undavia Group proceeds with its previously announced nomination, the Company may conduct multiple mailings prior to the Annual Meeting date to ensure stockholders have the Company’s latest proxy information and materials to vote. The Company will send you a new WHITE proxy card with each mailing, regardless of whether you have previously voted. We encourage you to vote every WHITE proxy card you receive. The latest dated proxy you submit will be counted.

##### Table of Contents

Q. | How will proxies be voted at the Annual Meeting?

A. | If you hold shares through a broker or nominee and do not provide the broker or nominee with specific voting instructions, under the rules that govern brokers or nominees in such circumstances, your broker or nominee will have the discretion to vote such shares on routine matters, but not on non-routine matters. As a result:

| • |  | Your broker or nominee will not have the authority to vote such shares with respect to Proposals 1 and 3 because the NYSE rules treat these matters as non-routine. Accordingly, such broker non-votes will have no effect on the outcome of the vote on these proposals.

| • |  | Your broker or nominee typically have the authority to vote such shares with respect to Proposal 2, because that matter is treated as routine under the NYSE rules. However, to the extent your broker provides you with the Undavia Group’s proxy materials it will not have discretion to vote on “routine maters,” including Proposal 2. In such circumstances, if you do not instruct your broker on how to vote your shares regarding Proposal 2, then your shares may not be voted on that matter. We urge you to instruct your broker about how you wish your shares to be voted using the WHITE voting instruction form.

To the extent present, broker non-votes will be counted as present for purposes of determining the presence of a quorum.

If you are a registered stockholder and no instructions are indicated on a properly executed proxy card submitted by you, the shares represented by the WHITE proxy will be voted “FOR” each nominee recommended by the Board in Proposal 1, and “FOR” Proposal 2 and Proposal 3, and in accordance with the proxy holder’s judgment for any other matter that may be properly brought before the Annual Meeting, or any adjournments or postponements thereof. If you return a WHITE proxy with only one (1) director nominee marked, only that nominee will be voted; should a WHITE proxy card be returned with more than two (2) director nominees marked, no votes will be cast with respect to the election of directors.

Q. | How do I cast a vote?

A. | You may vote by any one of the following means:

| • |  | By Internet. If you received a paper copy of a WHITE proxy card or voting instruction form by mail, you may submit your proxy over the Internet by following the instructions on the WHITE proxy card or voting instruction form.

| • |  | By Telephone. You may submit your vote by telephone by following the instructions on the WHITE proxy card if you received such materials by mail.

| • |  | By Mail. You may submit your proxy by completing, signing and dating your WHITE proxy card or voting instruction form and mailing it in the accompanying self-addressed envelope. No postage is necessary if mailed in the United States.

| • |  | Online, during the virtual Annual Meeting. If you hold shares in your name as the stockholder of record, you may vote online during the virtual Annual Meeting by following the instructions on the WHITE proxy card that you received. If you are a beneficial owner but not the stockholder of record, you may vote online at the virtual Annual Meeting only with a legal proxy obtained from your broker, trustee or nominee, as applicable. Beneficial owners should refer to “How do I register to attend the virtual Annual Meeting?” above for information on how to register to attend the virtual Annual Meeting in order to vote your shares at the Annual Meeting.

Properly completed and submitted WHITE proxy cards and voting instruction forms, as well as proxies properly completed and submitted over the Internet, will be voted at the virtual Annual Meeting in accordance with the instructions provided as long as they are received in time for voting and not revoked.

If your proxy is not revoked, we will vote it at the Annual Meeting in accordance with your instructions indicated on the WHITE proxy card or voting instruction form or, if submitted over the Internet, as indicated on the submission.

If you have already voted using a [•] proxy card sent to you by the Undavia Group, you have every right to change your vote and we strongly urge you to revoke that proxy by using the WHITE proxy card to vote in favor of ONLY the two (2) nominees recommended by the Board (Debra Fine and Anthony R.

Only the latest validly executed proxy that you submit will be counted – any proxy may be revoked at any time prior to its exercise at the Annual Meeting.

Q. | Where can I find the voting results after the Annual Meeting?

A. | We will announce the preliminary voting results at the Annual Meeting and will report the final voting results in a Current Report on Form 8-K, which we will file with the SEC within four business days after the meeting.

Q. | Who bears the cost of this proxy solicitation?

A. | GrafTech bears all proxy solicitation costs. In addition to solicitations by mail, our Board, officers and regular employees, without additional remuneration, may solicit proxies by telephone, fax, electronic transmission and personal interviews. We will request brokers, banks, custodians and other fiduciaries to forward proxy-soliciting materials to the beneficial owners of common stock and will reimburse them for their reasonable out-of-pocket expenses incurred in connection with distributing proxy materials.

As a result of the potential proxy solicitation by the Undavia Group, we will incur additional costs in connection with our solicitation of proxies. We have retained Mackenzie Partners, Inc. (“Mackenzie”), a proxy solicitation firm, to assist us in soliciting proxies for an aggregate fee of $[•] plus expenses [not to exceed $[•]] for assistance in connection with the solicitation. Mackenzie expects that approximately [•] of its employees will assist in the solicitation. The total amount to be spent for the Company’s solicitation of proxies in excess of that normally spent for an annual meeting is estimated to be approximately $[•], approximately $[•] of which has been accrued to date. The actual amount could be higher or lower depending on the facts and circumstances arising in connection with the solicitation.

Q. | What do I need to do now?

A. | You should carefully read and consider the information contained in this Proxy Statement. It contains important information about GrafTech that you should consider before voting.

Q. | Who should I call if I have questions about the Annual Meeting or voting your shares?

Additional Information

Proposals of Stockholders

Pursuant to Rule 14a-8 of the Exchange Act, we must receive notice of any stockholder proposal intended to be presented at our 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”) by no later than December 5, 2024 if it is to be included in the proxy statement and form of proxy relating to the meeting. Any such proposal must also comply with the other requirements of Rule 14a-8.

Under the advance notice provisions in our By-Laws, if you want to submit a proposal for the 2025 Annual Meeting for presentation at the meeting pursuant to Delaware corporate law (as opposed to inclusion in the proxy statement under Rule 14a-8) or intend to nominate a person as a candidate for election to the Board directly, the Corporate Secretary must receive the proposal or nomination between January 9, 2025 and the close of business on February 8, 2025, which are 120 days and 90 days, respectively, before the one-year anniversary of the Annual Meeting. If a stockholder fails to submit the proposal by February 8, 2025, the proposal will be considered untimely and the appointed proxies may exercise discretionary voting authority on the proposal.

If the date of the 2025 Annual Meeting has been changed more than 30 days from the anniversary date of the Annual Meeting, the Corporate Secretary must receive any such proposal or nomination no earlier than the 120th day before the 2025 Annual Meeting and by the later of the close of business of (1) the 90th day before the 2025 Annual Meeting; or (2) the 10th day following the day on which the date of the 2025 Annual Meeting is first disclosed publicly by the Company. Any proposals or nominations must comply with the other requirements of our By-Laws.

If you want to present a proposal before the 2025 Annual Meeting but do not wish to have it included in the proxy statement and proxy card, you must also give us written notice in accordance with the procedures and deadlines set forth in our By-Laws. Please address such correspondence to: GrafTech International Ltd., 982 Keynote Circle, Brooklyn Heights, OH 44131, Attention: Corporate Secretary.

Stockholders Sharing the Same Address

Some broker, bank and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that, if you are a beneficial owner of shares, only one copy of the proxy statement and annual report may have been sent to multiple stockholders in your household unless the Company has received contrary instructions. We will promptly deliver a separate copy of the documents to you if you write or call us at the following address or phone number: GrafTech International Ltd., 982 Keynote Circle, Brooklyn Heights, OH 44131, Attention: Investor Relations, telephone no. 216-676-2000. Beneficial owners who want to receive separate copies of the proxy statement and annual report in the future, or who are receiving multiple copies and would like to receive only one copy for their households, should contact their broker, bank or other nominee record holder.

Annual Report on Form 10-K

If you would like to receive, free of charge, a copy of our Annual Report on Form 10-K for the year ended December 31, 2023—as filed with the SEC, excluding exhibits—please write to us at the following address: GrafTech International Ltd., 982 Keynote Circle, Brooklyn Heights, OH 44131, Attention: Investor Relations. You can also view the Form 10-K by visiting the “Investors” section of our website, www.graftech.com. Information on, or accessible through, our website is not part of this Proxy Statement.

Appendix A: Non-GAAP Financial Measures

We have provided certain financial measures that are not in accordance with GAAP. EBITDA, adjusted EBITDA, adjusted net (loss) income, free cash flow and adjusted free cash flow are non-GAAP financial measures.

We define EBITDA, a non-GAAP financial measure, as net income or loss plus interest expense, minus interest income, plus income taxes and depreciation and amortization. We define adjusted EBITDA as EBITDA plus any pension and other post-employment benefit (“OPEB”) plan expenses or benefits, adjustments for public offerings and related expenses, non-cash gains or losses from foreign currency remeasurement of non-operating assets and liabilities in our foreign subsidiaries where the functional currency is the U.S. dollar, stock-based compensation expense, non-cash fixed asset write-offs, related party payable -Tax Receivable Agreement adjustments, and goodwill impairment charges. Adjusted EBITDA is the primary metric used by our management and our Board to establish budgets and operational goals for managing our business and evaluating our performance.

We monitor adjusted EBITDA as a supplement to our GAAP measures, and believe it is useful to present to investors, because we believe that it facilitates evaluation of our period-to-period operating performance by eliminating items that are not operational in nature, allowing comparison of our recurring core business operating results over multiple periods unaffected by differences in capital structure, capital investment cycles and fixed asset base. In addition, we believe adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and debt-service capabilities.

Our use of adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

| • |  | adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

| • |  | adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments, including any capital expenditure requirements to augment or replace our capital assets;

| • |  | adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our indebtedness;

| • |  | adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us;

| • |  | adjusted EBITDA does not reflect expenses or benefits relating to our pension and OPEB plans;

| • |  | adjusted EBITDA does not reflect public offerings and related expenses;

| • |  | adjusted EBITDA does not reflect the non-cash gains or losses from foreign currency remeasurement of non- operating assets and liabilities in our foreign subsidiaries where the functional currency is the U.S. dollar;

| • |  | adjusted EBITDA does not reflect stock-based compensation expense;

| • |  | adjusted EBITDA does not reflect the non-cash write-off of fixed assets;

| • |  | adjusted EBITDA does not reflect related party payable – Tax Receivable Agreement adjustments;

| • |  | adjusted EBITDA does not reflect goodwill impairment charges; and

| • |  | other companies, including companies in our industry, may calculate EBITDA and adjusted EBITDA differently, which reduces its usefulness as a comparative measure.

We define adjusted net (loss) income, a non-GAAP financial measure, as net (loss) income, excluding the items used to calculate adjusted EBITDA, less the tax effect of those adjustments. We believe adjusted net (loss) income is useful to present to investors because we believe that it assists investors’ understanding of the underlying operational profitability of the Company.

We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less capital expenditures. We define adjusted free cash flow, a non-GAAP financial measure, as free cash flow adjusted by payments made or received from the settlement of interest rate swap contracts and payments of the Change in Control (as defined below) charges that were triggered as a result of the ownership of our largest stockholder at the time falling below 30% of our total outstanding shares. We use free cash flow and adjusted free cash flow as critical measures in the evaluation of liquidity in conjunction with related GAAP

A-1 / GrafTech International Ltd. |2024 Proxy Statement |  |

##### Table of Contents

amounts. We also use these measures when considering available cash, including for decision-making purposes related to dividends and discretionary investments. Further, these measures help management, the audit committee, and investors evaluate the Company’s ability to generate liquidity from operating activities. For the purpose of this measure, a Change in Control occurred when Brookfield and any affiliates thereof ceased to own stock of the Company that constitutes at least thirty percent (30%) or thirty-five percent (35%), as applicable, of the total fair market value or total voting power of the stock of the Company (the “Change in Control”).

In evaluating EBITDA, adjusted EBITDA, adjusted net (loss) income, free cash flow and adjusted free cash flow, you should be aware that in the future, we will incur expenses similar to the adjustments in the reconciliations presented below. Our presentations of EBITDA, adjusted EBITDA, adjusted net (loss) income, free cash flow and adjusted free cash flow should not be construed as suggesting that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider EBITDA, adjusted EBITDA, adjusted net (loss) income, free cash flow and adjusted free cash flow alongside other measures of financial performance and liquidity, including our net (loss) income, cash flow from operating activities, and other GAAP financial measures.
