  35. Director Compensation Process

    Director Compensation Process Our director compensation program is intended to enhance our ability to attract, retain and motivate non-employee directors of exceptional ability and to promote the common interest of directors and shareholders in enhancing the value of our Common Stock. The Board reviews director compensation at least annually based on recommendations by the NCG Committee. The NCG Committee has the sole authority to engage a consulting firm to evaluate director compensation and since 2017 has engaged WTW to assist in setting director compensation. The NCG Committee reviews director compensation taking into account multiple factors, including pay practices and trends at publicly traded companies (including companies in our compensation peer group and surveys of S&P 500 compensation data), continued expansion of director, committee chair and lead director responsibilities, and the time commitment of Board and Committee service. The NCG Committee and the Board base their determinations on director compensation on recommendations from WTW and these factors. In (and effective) July 2024, based on these considerations, the Board approved an update to the Lead Independent Director retainer but otherwise maintained the non-employee director compensation package, which is described below. Effective as of January 1, 2025, the Board will have an independent Chair rather than a Lead Independent Director. The Chair of the Board will receive an annual cash retainer of $75,000 and an annual grant of time-based restricted stock units of $100,000.

  36. Director Compensation in 2024

    Director Compensation in 2024 The Company uses both cash and equity-based compensation to attract and retain qualified directors to serve on our Board of Directors, as follows:

  37. Director Compensation in 2024

    | Director Compensation Component | Amount | | Annual Awards | | | Annual cash retainer (paid quarterly) | $125,000 | | Annual time-based restricted stock units (“RSU”)(one-year vesting) | $175,000 | | Incremental Awards for Board Leadership(1) | | | Annual cash fee for chair: (i) Nominating and Corporate Governance Committee, and (ii) Stewardship Committee | $15,000 | | Annual cash fee for chair: Compensation and Management Development Committee | $20,000 | | Annual cash fee for chair: Audit Committee | $25,000 | | Annual cash fee for Lead Independent Director | $40,000 | | (1) Effective as of July 2024, the Board approved an increase to the Lead Independent Director retainer from $35,000 to $40,000. Effective as of January 2025, the Board has an independent Chair rather than a Lead Independent Director. Effective as of March 1, 2025, the Board formed a new Finance and Business Review Committee and approved an annual cash retainer for any non-employee chair in the amount of $25,000. | |

  38. Director Compensation in 2024

    Newly-elected directors receive a pro-rata equity award for a partial year of service. In addition to the above, Directors are reimbursed for expenses incurred in attending board, committee and shareholder meetings. Directors are also reimbursed for reasonable expenses associated with other business activities that benefit the Company, including participation in director education programs. Occasionally, a director may use Company-provided aircraft for travel to Board meetings. We generally do not provide perquisites to our directors, other than small gifts provided at Board meetings and upon retirement.

  40. Director Compensation in 2024

    U.S. non-management directors are entitled to participate in the Company’s 2008 Deferred Compensation Plan (“2008 Deferred Plan”), which is an unfunded, nonqualified deferred compensation plan that allows directors the opportunity to defer all or a portion of their cash compensation and RSUs in exchange for a future payment amount equal to their deferments plus or minus certain amounts (including dividend equivalents) based on the market performance of specified measurement funds selected by the participant. Deferrals by directors under the 2008 Deferred Plan, including deferrals of RSUs, do not receive above-market earnings. Directors Blackwell, Brown, Galante, Hill, Ihlenfeld, Kissire and Rucker were the only directors that made contributions to, or had balances in, this plan during 2024.

    (1)Ms. Ryerkerk is not included in this table because she was an employee of the Company during 2024 and received no compensation for her services as a director. Ms. Blackwell and Mr. Brown did not stand for re-election at the 2024 Annual Meeting of Shareholders and departed the Board thereafter. (2)Includes amounts earned for the annual retainer and committee chair and Lead Independent Director fees for the respective independent directors, as applicable. (3)Represents the grant date fair value of 1,114 RSUs granted to each current non-management director (910 RSUs granted to Mr. Chinn in September 2024, which included a prorated amount of RSUs for time served from his September 15, 2024 election effective date through April 2025) in May 2024 under the Amended and Restated 2018 Global Incentive Plan (the “2018 GIP”). The fair value of RSUs granted to our non-management directors as part of the annual award was calculated to be $156.96 per RSU ($120.17 for Mr. Chinn), which reflects the average of the high and low market price of our Common Stock as reported by the NYSE on the applicable grant date discounted for lack of dividend participation. As of December 31, 2024, each current non-management director listed in the table owned 1,114 RSUs, except Mr. Chinn who owned 910 RSUs.

  51. Compensation Philosophy and Elements of Pay

    | The CMDC establishes overall target total compensation for each NEO and then allocates that compensation among base salary, annual incentive and long-term incentive opportunities. While no specific formula is used to determine the allocation between cash and equity-based compensation, when allocating these compensation elements we generally utilize a compensation mix more heavily weighted towards performance-based compensation. The CMDC strongly believes that the CEO’s compensation should be heavily weighted towards variable and long-term incentive awards to align compensation with shareholder interests. The target pay mix for our CEO for 2024 is highlighted to the right, with approximately 90% performance-based or “at risk.” | |

  52. Compensation Philosophy and Elements of Pay

    Target Level of Compensation To establish the appropriate target level of compensation for the CEO and each other NEO, each compensation element is reviewed by the CMDC relative to market data for the role within our compensation peer group. The CMDC’s philosophy is to use the median of our compensation peer group as a guideline for establishing target total direct compensation (base salary plus target annual incentive plan award plus the grant date value of long-term incentive awards). Individual position considerations such as experience level, scope of role, personal impact on Company results, individual performance and relative compensation amounts across executives also impact how compensation is calibrated relative to market norms. The CMDC also considers general industry compensation survey data presented by its independent compensation consultant, since the talent market for many of our executives is broader than the companies in our compensation peer group. Although the CMDC strives to set target compensation at levels that are competitive with our compensation peer group, it does not rigidly adhere to any particular market reference point in determining executive compensation. Use of Peer Groups Compensation Peer Group. Each year, the CMDC’s independent compensation consultant provides an analysis of compensation data and practices from a select group of peer companies in the chemical industry. The CMDC, with the assistance of its independent consultant, identifies the companies to be included in the compensation peer group.

  53. Compensation Philosophy and Elements of Pay

  54. Compensation Philosophy and Elements of Pay

    Our CMDC reviews the compensation peer group annually in consultation with its independent compensation consultant to assess whether the individual companies in the group continue to be appropriate and that the group as a whole is appropriate. The CMDC reviewed the comparator group during 2024 and determined not to make any modifications to the compensation peer group used during 2023. The compensation peer group used by the CMDC in setting target pay for 2024 was as follows:

  55. Compensation Philosophy and Elements of Pay

    | Compensation Peer Group | | | Air Products and Chemicals, Inc. | LyondellBasell Industries NV | | CF Industries Holdings, Inc. | Olin Corporation | | Corteva, Inc. | PPG Industries, Inc. | | DuPont de Nemours, Inc. | RPM International Inc. | | Eastman Chemical Company | The Chemours Company | | Ecolab Inc. | The Mosaic Company | | Huntsman Corporation | The Sherwin-Williams Company | | International Flavors & Fragrances Inc. | Westlake Corporation | | Linde plc | |

    Relative Stock Performance Peer Group. The companies used to determine relative total shareholder return (relative TSR) for purposes of determining 2024-2026 PRSU payouts consist of the companies in the Dow Jones US Chemical Industry Index as of December 31, 2023. The CMDC believes the companies in this index are representative of companies that face similar operational, demand, competitive and macroeconomic environments as we do and therefore represent an effective group for comparison of our relative TSR results. These companies are listed below:

  57. Compensation Decisions

    Compensation Decisions Base Salary The CMDC reviews and approves annually the base salaries for each of the NEOs. The CMDC also approves any increases to the base salaries of any officers at the time of any promotion or other role change. In setting base salaries, the CMDC considers a number of factors, including (i) the scope, complexity, and financial or business impact of the executive’s position, (ii) the executive’s level of expertise, experience (including time in the specific role) and individual performance, (iii) internal pay equity among the executive team, and (iv) how the executive’s base salary compares to the base salary of similarly situated executives at companies in our compensation peer group or in compensation surveys we review. As a result of these factors, base salaries may be set higher or lower than the median level of similarly situated executives at companies in our compensation peer group, when appropriate. The Company’s pay philosophy is that, in general, the pay for individuals new to a role should work toward the desired competitive pay positioning over time as they gain experience in the role. In most cases, the individual’s pay is expected to reach the desired competitive positioning within one to three years after taking the role. Similarly, an individual with significant experience and demonstrated success in the role or a similar role might have pay positioned above the market median. Based on the application of the above factors, the CMDC approved base salaries effective in July 2024 for the NEOs. Ms. Ryerkerk, Mr. Kyrish and Mr. Murray received salary increases of approximately 4%, 17% and 4%, respectively, intended to maintain competitiveness with our peer group. Given that 2024 was Mr. Kyrish’s first full year as Chief Financial Officer following his appointment in November 2023, his increase in salary was also intended to reflect the complexity and breadth of this role. His base salary following the increase still remained below the median for his role as compared to our peer group. Base salaries as of December 31, 2024 are set forth in the table below.

    Annual Incentive Plan Awards Plan Summary The CMDC approves a target annual incentive plan award, expressed as a percentage of salary, for each NEO based in part on market data for his or her position and level within the organization. 2024 target bonus percentages for each NEO, in their current roles, are shown below. For 2024, the actual annual incentive plan payouts could range from 0% – 200% of the target award based on our achievement of financial and stewardship performance targets and the achievement by the NEO of individual personal objectives established at the beginning of the year. See "2024 Business Performance Summary” below for the performance measures established for 2024 and the results against them.

  60. Compensation Decisions

    Individual performance modifier for NEOs other than the CEO. The CMDC believes that individual performance modifiers are valuable compensation components that can reward qualitative performance and value creation within each NEO’s area of responsibility or, alternatively, reduce payouts for individual performance that does not meet performance expectations. Our CEO recommends to the CMDC an individual performance modifier for each other NEO after the end of the fiscal year based on the CEO’s assessment of each such NEO’s performance against his or her individual objectives. The individual performance modifier does not apply to the annual incentive plan award granted to our CEO. The CMDC believes that the CEO holds ultimate accountability for the performance of the organization as a whole, and therefore the CEO’s annual incentive plan payout is based solely on the Company’s performance against the quantitative performance objectives set forth by the CMDC, which are described in detail below under "2024 Business Performance Summary.” Payout Formula. The formula for determining annual bonus payouts is as follows:

  61. Compensation Decisions

    | TARGET BONUS | | BUSINESS RESULTS | INDIVIDUAL RESULTS | | ANNUAL BONUS | | Eligible EarningsX | Target Bonus %X | Business Performance Modifier [0-200%]X | Individual Performance Modifier [0-150%] | = | Annual Performance Bonus Award [0-200%] | | | | | (Does not apply to CEO) | | (capped at 200% aggregate payout) |

  62. Compensation Decisions

    Eligible earnings is defined as the actual amount of base pay that is earned for the year, including the effect of any base salary adjustments made part-way through the year. The annual incentive plan award is paid in February or March of the year following the end of the performance period. Target Annual Award Amounts. The 2024 target annual incentive plan award for each of the NEOs is set forth in the following table. In February 2024, the CMDC determined to increase the target annual incentive plan bonus amount by 10% and 15%, respectively, of eligible earnings for Ms. Ryerkerk and Mr. Kyrish to more closely align with competitive benchmarking for these roles. As noted above, given that 2024 was Mr. Kyrish’s first full year as Chief Financial Officer following his appointment in November 2023, his increase in target annual incentive plan award was also intended to reflect the complexity and breadth of this role.

    2024 Company Performance Goals and Objectives The 2024 annual incentive plan metrics were set in February 2024 as Operating EBITDA1, free cash flow2, and stewardship goals relating to occupational and process safety, the environment and product quality. Within each of these performance metrics, three incremental performance levels are established: threshold, target and superior. Target goals require a high level of performance during the one-year performance period to be achieved. Threshold and superior levels are designed to provide a smaller award, or potentially no award, for lower levels of performance (threshold) as well as to reward exceptional levels of performance with higher payouts (superior). The structure of the 2024 annual incentive plan remained substantially the same as the structure used in recent years, as the CMDC continues to believe that the structure and metrics appropriately motivate and reward achievement of key short-term objectives that drive company performance and shareholder value. When the CMDC set the performance goals for the 2024 annual incentive plan in February 2024, they considered our performance in 2023, our 2024 annual operating plan, our strategic plan to drive long-term earnings growth over time in various economic scenarios, and our continued progress toward objectives for the M&M Acquisition as previously communicated to shareholders. The CMDC set the threshold, target (or target range) and superior levels for Operating EBITDA and free cash flow to be in line with our internal, confidential business plan as of February 2024, taking into account potential business scenarios and risks as well as known business headwinds and tailwinds. The CMDC decided to continue to set a range for the achievement of target results for Operating EBITDA and free cash flow due to (i) economic volatility, (ii) uncertainty regarding the pace of recovery of the M&M Business in 2024 and (iii) and the general difficulty of forecasting results with precision given the complexities of the industry in which we operate.

    2024 Individual Performance Assessments Purpose and Process Process for Former CEO. At the beginning of 2024, Ms. Ryerkerk and the CMDC jointly set the Company’s annual goals and objectives relevant to CEO compensation after considering input from all independent members of the Board. Performance against the objectives was reviewed throughout the year on a periodic basis. Process for Other NEOs. At the beginning of 2024, Ms. Ryerkerk developed the individual performance objectives for each other NEO in consultation with each such NEO, subject to review and approval by the CMDC. At the beginning of 2025, shortly after assuming the CEO role, Mr. Richardson submitted to the CMDC and the full Board a performance self-assessment outlining his self-assessment of his 2024 achievement of company and individual objectives and contributions to our financial performance in his role as COO for 2024. Mr. Richardson and the CMDC also conducted a final review with each of his direct reports, including Messrs. Kyrish, Kelly and Murray, and rated their individual performance as well as contributions to company performance. Mr. Richardson then submitted to the CMDC a performance assessment and compensation recommendation for each of these NEOs. CMDC Decisions. The CMDC referred to these individual performance evaluations in determining any merit increases in base salary as well as the individual performance modifiers for the annual incentive plan. The CMDC, with input from the full Board and its independent compensation consultant, determined in December 2024 in executive session Mr. Richardson’s base salary, target bonus and long-term incentive awards for 2025. See “NEO Transitions” below. NEO Performance Assessments for 2024 Our NEOs’ 2024 individual performance objectives revolved around the following primary themes: •delivering earnings growth across our businesses; •driving actions to increase efficiency and reduce costs; •taking actions to progress toward business goals in a difficult macroeconomic environment; •managing earnings headwinds and other challenges effectively; and •developing talent to advance successor readiness for critical roles and align talent to key business opportunities. The CMDC determined to cap individual modifiers for NEOs at 100% for 2024, such that no NEO’s annual incentive plan payout was increased by the individual performance modifier. Based on the above business and individual results, and in accordance with the terms of the separation agreement with Ms. Ryerkerk, as described in “Potential Payments Upon Termination or Change In Control — Post-Termination Table — Ms. Ryerkerk's Separation Agreement”, the CMDC awarded annual incentive awards to the CEO and remaining NEOs as set forth in the “2024 Summary Compensation Table” under the “Non-Equity Incentive Plan Compensation” column. NEO Transitions As previously announced, Ms. Ryerkerk was terminated without cause as Chair, Chief Executive Officer and President, as of the end of the day on December 31, 2024, and Mr. Richardson was appointed Chief Executive Officer and President as of January 1, 2025. The CMDC established a competitive pay package for Mr. Richardson as a newly-tenured CEO, based on peer and market data, and consistent with our established pay for performance approach. His annual base salary was set at $1,150,000, with a target annual incentive plan bonus of 125% of his base salary. In addition, consistent with our pay for performance philosophy, the 2025 long-term incentive awards for Mr. Richardson were comprised of an “annual award” with a grant date fair value of $7.5 million, consisting of 70% PRSUs

    Time-Based Stock Options. Time-based options granted to NEOs under the 2024 LTIP vest in three equal annual installments on February 15, 2025, 2026 and 2027. Such stock options will only have value to the extent our share price appreciates above the exercise price, which was determined based on the high and low trading prices on the grant date of the award. Payouts on Previously-Granted LTIP Awards The PRSUs granted to NEOs as part of the 2022 LTIP were earned and paid out based on Adjusted EPS and ROCE over a performance period of January 1, 2022 through December 31, 2024. As noted in the table below, Cumulative Adjusted EPS over the 2022-2024 performance period was $33.17, our fourth highest three-year Adjusted EPS performance result but was below the threshold for 2022 LTIP payout. Efforts to drive business and profit growth and reduce costs through synergy actions related to the M&M Acquisition were more than offset by weaker-than-expected demand conditions in our global end markets which limited our ability to profitably increase volume in Engineered Materials and the Acetyl Chain. Cumulative ROCE performance over the 2022-2024 performance period was 14.3%, which was above the target range for ROCE.

  76. Compensation Governance

    Compensation Governance Compensation and Management Development Committee Oversight The CMDC, which consists entirely of independent directors, is responsible for establishing compensation policies and programs that are consistent with our business strategy and aligned with our shareholders’ interests. Specifically, the CMDC is responsible for: •reviewing and approving the corporate goals and objectives relevant to the compensation of the CEO and our other NEOs; •evaluating the performance and compensation of the CEO and our other NEOs in light of their established goals and objectives; •reviewing and approving both target and actual pay levels of the CEO and our other NEOs; and •reviewing and approving incentive and equity-based compensation plans, including our annual incentive plan and our long-term incentive plans, and all grants of awards under such plans to our NEOs. Role of the CMDC’s Independent Compensation Consultant Pursuant to its charter, the CMDC has authority to retain and terminate any compensation consultant. During 2024, the CMDC retained Willis Towers Watson PLC (“WTW”) as its independent compensation consultant to advise it in connection with executive compensation matters. Representatives of WTW regularly attend CMDC meetings as requested by its chair, and report directly and exclusively to the CMDC on matters relating to compensation for the NEOs. In 2024, WTW provided the following services to the CMDC: •reviewed and provided guidance on compensation plan design; •reviewed the composition of our compensation peer group; •conducted an analysis of our compensation for the CEO and the other NEOs, and assessed how target and actual compensation aligned with our philosophy and objectives as well as executive compensation paid by our compensation peer group; and •provided market data, historical compensation information, internal equity comparisons, share usage and dilution data, competitive practice information, and recommendations regarding compensation trends, compensation strategy and our proxy statement. In addition, WTW analyzed and benchmarked non-employee director compensation at the request of the NCG Committee, the independent committee responsible for non-employee director compensation. In addition to the executive compensation services provided to the CMDC, and the director compensation services provided to the NCG Committee, specialized teams at WTW and affiliates provided certain services to the Company in 2024 at the request of management consisting of (i) pension valuation and other services for broad-based defined benefit plans that we sponsor; (ii) total rewards consulting services, including advice in connection with union

  77. Additional Information Regarding Executive Compensation

    The benefits described above are also described in the notes to the “2024 Summary Compensation Table”, to the extent applicable in 2024. The CMDC reviews these arrangements regularly to assure they continue to fulfill business needs. Retirement Our NEOs participate in our various employee benefit plans designed to provide retirement income. Our qualified and non-qualified pension plans provide a retirement income base for eligible and participating employees, and our qualified and non-qualified 401(k) and supplemental savings and retirement plans permit additional retirement savings. To encourage retirement savings under the qualified and nonqualified 401(k) plans, we provide an employer matching contribution. We limit eligible compensation for employer contributions under the qualified and non-qualified 401(k) plans to annual base salary for our NEOs. As a result, the CMDC’s decisions to grant incentive awards (whether cash or equity) do not create any additional retirement benefits under these plans for our NEOs. Our U.S. defined benefit pension plan, the Celanese Americas Retirement Pension Plan, was frozen as of the end of 2013. Messrs. Richardson, Kyrish and Kelly, who were employed by us before the freeze date, participate in the plan. For more information about these plans and NEO participation in them, see “2024 Summary Compensation Table”, “2024 Pension Benefits Table” and “2024 Nonqualified Deferred Compensation Table”. Severance Plan In order to offer a competitive benefit that allows for consistent administration without negotiations of special payments, we have a Designated Roles Member Severance Benefits Plan (“Severance Plan”), formerly known as the Executive Severance Benefits Plan, for our NEOs. The Severance Plan provides cash payments upon involuntary termination without cause (as defined in the Severance Plan), but is not available in the event of a change in control to individuals who have a change in control agreement as described below. See “Potential Payments Upon Termination or Change In Control” for additional information. Effective January 1, 2025, the CMDC approved changes to the Severance Plan to, among other things, reduce the severance benefit thereunder from 150% of base salary and target bonus to 100% of base salary and target bonus (or from 200% to 150% in the case of the CEO) for all of our executive officers, including our active NEOs. Change in Control Agreements We have change in control agreements with each of our NEOs to ensure that management will objectively consider potential transactions that may benefit shareholders without regard to any potential impact on their continued employment. The change in control agreements provide for a cash payment to be made following a termination of employment by the Company without cause or by the NEO with good reason (as defined in the agreements) within two years following a change in control. See “Potential Payments Upon Termination or Change In Control” for additional information. In approving the form of change in control agreement, the CMDC considered the prevalence and terms of such agreements at the companies in our compensation peer group based on data collected for the Company by the CMDC’s independent compensation consultant at the time. The CMDC also determined that the uniform non-compete and non-solicit clauses contained in such agreements provide a significant benefit to the Company. None of the change in control agreements in effect with our NEOs contains a tax gross-up. No Employment Agreements We do not have any employment agreements with any of our NEOs. All of our currently employed NEOs are “at will” employees. For a description of our recent separation agreements with Ms. Ryerkerk and Mr. Kelly, please refer to “Potential Payments Upon Termination or Change In Control — Post-Termination Table — Ms. Ryerkerk's Separation Agreement” and “Potential Payments Upon Termination or Change In Control — Post-Termination Table — Mr. Kelly's Separation Agreement.” Executive Stock Ownership Requirements

  78. Additional Information Regarding Executive Compensation

    The CMDC has adopted stock ownership guidelines for our NEOs, as shown in the table below. The types of securities that count toward required share ownership include only (i) shares of Common Stock owned outright, whether individually or through beneficial ownership in a trust or partnership, (ii) shares of Common Stock or share equivalents held in a Company-sponsored deferred compensation or retirement plan, and (iii) 60% of unvested time-based RSUs that will vest within one year of the measurement date. Unvested PRSUs and unexercised stock options do not count toward required share ownership. Each NEO has five years from the date of hire or promotion to achieve the required ownership level. Failure to meet stock ownership requirements, or failure to make a meaningful effort to do so, may result in the NEO not receiving future base salary increases or long-term incentive awards, and may also make the NEO ineligible for promotion. The following table sets forth the ownership requirement (expressed as a multiple of base salary) for each of our NEOs. As of December 31, 2024, with reference to base salary as of the end of 2024, and — whether using a reference stock price of $113.16, the weighted average of 2024 share trading prices, or $69.21, the closing stock price on December 31, 2024, all NEOs were in compliance with our current ownership guidelines or were on track for compliance by the applicable deadline based on their respective hire or promotion dates.

  79. Additional Information Regarding Executive Compensation

    (1) Calculated using $113.16, the weighted average share trading price in 2024, and base salary as of the end of 2024. Compliance statuses shown are as of December 31, 2024, and thus do not reflect the transitions of Ms. Ryerkerk, Mr. Richardson or Mr. Kelly. Executive Compensation Clawback Policies In order to further align management’s interests with the interests of shareholders and support good governance practices, the CMDC maintains robust clawback policies (also known as recoupment policies) applicable to bonuses paid out under our annual incentive plan and to all long-term incentive plan awards. Our clawback policy with respect to financial restatements requires recoupment or cancellation of incentive-based compensation (defined consistently with SEC Rule 10D-1 and associated NYSE listing requirements) from SEC Section 16 officers, and allows recoupment or cancellation of such compensation from other incentive plan participants, in each case in the event of a financial restatement, including for specified periods following termination of employment with us, all in accordance with SEC Rule 10D-1 and associated NYSE listing requirements. Our separate clawback policy with respect to detrimental conduct or the violation of restrictive covenants allows recoupment or cancellation of an award (including both time-based and performance-based equity awards) in the case of (i) an act or omission constituting a violation of the Company’s business conduct policy or other policy causing material financial harm to the Company, (ii) fraud or ethical misconduct contributing to the need for a financial restatement, (iii) an act for which the employee or the Company could be held civilly or criminally liable, or (iv) violations of restrictive covenants relating to (a) disclosing confidential or proprietary information, (b) competing with us, (c) soliciting or hiring employees or certain former employees, and (d) soliciting any consultants of ours to cease working with us, in each case, for a specified period following the termination of the award recipient’s employment with us for any reason. In addition, pursuant to Section 304 of the Sarbanes-Oxley Act of 2002, if we are required to restate our financial statements due to material noncompliance with any financial reporting requirements as a result of misconduct, the CEO and Chief Financial Officer will be required to reimburse us for any bonus or other incentive-based or equity-

  80. Additional Information Regarding Executive Compensation

    based compensation received during the 12 months following the first public issuance of the non-complying document, and any profits realized from the sale of securities of the Company during those 12 months. Policies and Practices Related to the Grant of Equity Awards At each February meeting, it is the CMDC’s long-standing practice to approve the granting of annual equity awards for the then-current fiscal year, with the grant date generally being the third trading day after the release of the Company’s annual report on Form 10-K. Other than grants made in connection with hiring, promotions, or to replace certain new hire grants once they vest and/or are exercised, equity awards are granted to NEOs at the same time that equity awards are granted to all other employees who are eligible for such awards. The Company may change these practices in the future. Options are granted with an exercise price equal to the average of the high and low trading prices of our Common Stock on the grant date. In 2024, the CMDC did not take into account material nonpublic information when determining the timing and terms of equity awards, and we did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. See “Certain Equity Award Grants” for additional information.

  85. 2024 Summary Compensation Table

    (4)Consists entirely of the respective aggregate change in the actuarial present value of each individual’s pension benefits based on a discount rate of 5.56% for 2024. The values shown assume retirement from the Celanese Americas Retirement Pension Plan (“CARPP”) and the Celanese Americas Supplemental Retirement Savings Plan (“CASRSP”) (as applicable) for Messrs. Richardson, Kyrish and Kelly at age 65 with a life only benefit under the CARPP and the CASRSP, as applicable. See “2024 Pension Benefits Table” and accompanying text. (5)The amounts reported in this column with respect to fiscal 2024 consist of the following: (a) Aggregate Company contributions, including matching and retirement contributions made for 2024, under the Company’s tax-qualified and non-qualified defined-contribution retirement plans, including the Celanese Americas Retirement Savings Plan (“CARSP”), a tax-qualified, defined contribution (401(k)) plan, and the CASRSP, an unfunded, non-qualified defined contribution plan: Ms. Ryerkerk, $145,750, Mr. Richardson, $89,142, Mr. Kyrish $71,500, Mr. Kelly $77,000, and Mr. Murray $61,600. The CARSP is available to substantially all of our U.S. employees, including all the NEOs based in the U.S. The plan is subject to the provisions of ERISA. Each eligible participant is entitled to a 6% match of his or her pre-tax and after-tax contributions to the CARSP and an allocation of 5% of his or her salary up to the Code Section 401(a)(17) limit ($345,000 in 2024) in lieu of the former pension plan contribution under the Celanese Americas Retirement Pension Plan (“Retirement Contributions”). The amount contributed to the plan by or on behalf of a participant is limited by Code Section 415 and is credited with earnings based on the earnings rate of an investment fund maintained for investments under the CARSP chosen by the participant. Each of the NEOs is entitled to an allocation under the CASRSP equal to (a) Retirement Contributions limited by Code Section 415 and not contributed to the CARSP, and (b) 6% of his or her salary in excess of the compensation limits under the CARSP (“Excess Earnings Contributions”). The amount contributed to the plan on behalf of a participant is credited with earnings based on the earnings rate of an investment fund maintained for investments under the CARSP which is currently the 1-3 year Government/Credit Bond Index Fund. Additional information about the CASRSP is set forth in the “2024 Nonqualified Deferred Compensation Table” and accompanying text. (b) The Company provides reimbursement of up to $10,000 annually (with no tax gross-up) for personal financial planning and wealth management services to the NEOs. From time to time, our NEOs travel for business purposes on Company-provided aircraft for security and safety reasons and to maximize the efficiency of their travel and availability for Company business. Perquisites and personal benefits were excluded for all of the NEOs to the extent that the total value of all perquisites and personal benefits for an NEO was less than $10,000. In addition, the table does not include any amounts for personal benefits provided to any of the NEOs for which we believe there is no aggregate incremental cost to us. No tax gross-ups were paid to any NEO during 2024. (6)The stock awards for 2024 consisted of annual equity awards of PRSUs under the 2024 long-term incentive plan (LTIP). The per-unit fair value of the 2024 PRSUs was calculated to be $152.00, as determined using a Monte Carlo simulation model with reference to the date of grant, discounted for lack of dividend participation and for implications of the potential application of the TSR modifier feature, and adjusted for a performance premium. Payout of such PRSUs can range from a minimum of 0% to a maximum of 200% of target. The target potential values of the award of PRSUs for the NEOs granted in 2024 using the fair value discussed above, and the maximum potential values of the PRSUs for the NEOs granted in 2024 using the closing stock price on the date of grant, assuming performance at the target and maximum levels of performance conditions, respectively, are set forth below. Actual performance, and the stock price at the eventual payout dates, is uncertain.

    (7)The fair value of the stock options granted to our NEOs under the 2024 LTIP as part of the annual award was calculated to be $51.11 per stock option. The fair value of each stock option granted is estimated on the grant date using the Black-Scholes option pricing method. Stock option awards are granted with an exercise price equal to the average of the high and low price of the Company's Common Stock on the grant date. The expense related to the Company's stock option awards is recognized over the vesting period of the respective grant on a straight-line basis. Stock options issued under the 2024 LTIP have a contractual term of ten years and vest in three annual installments. The Company recognizes forfeitures as they occur. The assumptions used in the Company’s Black-Scholes option pricing model for stock options include expected volatility, expected life, risk-free interest rate, and expected dividends. The computation of the expected volatility assumption used in the Black-Scholes calculation for new grants is based on the historical volatility of the price of the Company’s Common Stock for periods commensurate with the expected life. When establishing the expected life assumptions, as the Company does not have sufficient historical exercise or post-vest cancellation activity, the expected life of stock options is determined using the “simplified” method, as prescribed in the SEC’s Staff Accounting Bulletin No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the stock option. The risk-free interest rate is determined by converting the semi-annual zero-coupon U.S. Treasury rates as of the grant date to continuously compounded rates. The continuously compounded risk-free rate is then selected that is commensurate with the expected life. The dividend yield is based on the quotient of the Company’s latest quarterly dividend annualized and the grant price of the Company’s Common Stock.

  108. 2024 Pension Benefits Table

    Effective January 1, 2001, the plan began providing benefits for covered employees hired after December 31, 2000, based on a different benefit formula (“Cash Balance Plan”). The Cash Balance Plan provides that for each plan year that employees work as defined, we credit 5% of the employee’s annual pensionable earnings (up to Internal Revenue Code limits) to a hypothetical plan account that has been established for each employee, and credit that account with interest. For a given year, the plan’s interest rate is the annual rate of interest on 30-year United States Treasury Securities for the August before the first day of that year. Employees vest in their accrued benefit after completing three years of service with us. If employees are vested when they leave the Company, they have the option to take their account balance with them, either in a lump-sum payment or as an annuity. Employees also have the choice to leave their account balance in the plan until the normal retirement age of 65. The amount of benefit depends on the employee’s pay and any interest earned on the Company contributions. Once vested, survivor benefits are applicable to married participants. In connection with amendments to the CARPP in 2013, accrued benefits under the CARPP were frozen as of December 31, 2013, no further contributions will be made to the CARPP other than interest credits for the cash balance participants (Mr. Richardson, Mr. Kyrish and Mr. Kelly), and future pension-related contributions (“Retirement Contributions”) will be made to the CARSP or the CASRSP, depending on the level of eligible earnings of the participant.

The amount contributed to the plan on behalf of a participant is credited with earnings based on the earnings rate of one of the funds maintained for investments under the CARSP, which is currently the 1-3 year Government/Credit Bond Index Fund. The aggregate annualized rate of return for the credited earnings in 2024 was 5.40%. Beginning in 2015, participants are credited with earnings based on the performance of certain hypothetical investment choices selected by the participant. These investment choices are the same investment choices available under the CARSP (other than the Celanese Stock Fund). Participants may change their investment elections at any time under the same rules that apply under the CARSP. Distributions under the CASRSP are in the form of a lump sum payment which is paid as soon as administratively practicable after termination of employment for most participants. Distributions to participants who are top 50 key employees of the Company must be delayed six months following termination based on Code Section 409A requirements. 2008 Deferred Plan.

Ms. Ryerkerk and Mr. Kelly were the only NEOs that made contributions to, or had a balance in, this plan during 2024.

    Potential Payments Upon Termination or Change In Control The particular events that trigger payments to our NEOs upon termination of employment or a change in control are generally defined in our Severance Plan and the individual executives’ change in control agreements, deferred compensation agreements, and PRSU, RSU or stock option award agreements. The CMDC believes that the primary benefits to the Company of employment agreements are the non-competition and non-solicitation provisions found therein. In order to achieve the benefit of these provisions without incurring the generally negative obligations associated with employment agreements, the CMDC offers a more limited change in control agreement to each executive officer. However, the deferred compensation agreements and PRSU, RSU and stock option award agreements are still effective and provide for some potential payments upon termination and change in control as described below. Severance Plan Our Designated Roles Member Severance Benefits Plan, formerly known as the Executive Severance Benefits Plan (“Severance Plan”) applies to all our executive officers and other eligible employees. As of December 31, 2024, the Severance Plan provided, upon involuntary termination without cause or termination by the executive for good reason, for the payment of (i) 150% of one year’s base salary for named executive officers (200% for the CEO); (ii) 150% of one year’s annual incentive plan bonus award for named executive officers (200% for the CEO) based on target Company performance and a 1.0 individual modifier; and (iii) a prorated portion of the annual incentive plan award for the year in which the termination occurs based on actual Company performance and a 1.0 individual modifier. The Severance Plan also provides for the payment of premiums for post-termination health insurance coverage (“COBRA premiums”) for a period of one year from the date of termination (eighteen months for the CEO) and out-placement benefits. As a condition to the receipt of any benefits under the Severance Plan, an executive must agree to standard release, non-compete, non-solicitation, and confidentiality provisions. In addition, the Severance Plan provides that the vesting of long-term incentive or other equity awards upon termination without cause will be governed by the terms of the applicable award agreements. Executives who are involuntarily terminated for any other reason (e.g., death, disability, retirement, termination for cause) are not eligible to receive severance benefits under the Severance Plan. Effective as of January 1, 2025, the CMDC amended the Severance Plan to, among other things, reduce the severance benefit from 150% of base salary and annual incentive plan bonus to 100% of base salary and annual incentive plan

    bonus (or from 200% to 150% in the case of the CEO) for our executive officers, including our then-employed NEOs. Given the timing of her termination, Ms. Ryerkerk was entitled to severance benefits under the previous Severance Plan terms. For more information on Ms. Ryerkerk’s and Mr. Kelly’s Separation Agreements, see “Potential Payments on Termination or Change in Control — Post-Termination Table — Ms. Ryerkerk's Separation Agreement” and “Potential Payments on Termination or Change in Control — Post-Termination Table — Mr. Kelly's Separation Agreement” below. Change in Control Agreements We have change in control agreements with each of our actively employed executive officers. The change in control agreements provide for a payment to be made to these officers following a termination of employment by the Company without cause or by the officer with good reason within two years following a change in control or following the first public announcement of a potential change in control transaction, provided certain conditions are satisfied. These benefits are in lieu of payments under the Severance Plan. Generally, the change in control agreements provide for each executive officer to receive: •a lump sum payment equal to up to two times (three times for the CEO) the sum of: ▪the named executive officer’s then current annualized base salary, and ▪the higher of (a) the officer’s target bonus in effect on the last day of the fiscal year that ended immediately prior to the year in which the date of termination occurs, or (b) the average of the cash bonuses paid by the Company to the NEO for the three fiscal years preceding the date of termination; •a pro rata bonus award under our annual incentive plan award for the year in which the termination occurs based on actual Company performance; •group health and dental coverage for the NEO and his or her dependents for a period of up to eighteen months following the date of termination; and •out-placement benefits for up to 12 months at the option of the executive officer. The change in control agreements do not contain a tax reimbursement provision and require a cutback of benefits to avoid excise taxes if the after-tax benefit to the executive is greater than without the cutback. Each change in control agreement has a two-year term that is automatically renewed for successive two-year terms unless 90 days’ notice of non-renewal is given by either party to the agreement.

    | For purposes of the change in control agreements: | | | | “cause” generally means (i) a willful failure to perform one’s duties (other than as a result of total or partial incapacity due to physical or mental illness) for a period of 30 days following written notice by the Company of such failure; (ii) conviction of, or a plea of nolo contendere to, (x) a felony under the laws of the United States or any state thereof or any similar criminal act in a jurisdiction outside the United States or (y) a crime involving moral turpitude; (iii) willful malfeasance or willful misconduct which is demonstrably injurious to the Company or its Affiliates (as defined); (iv) any act of fraud; (v) any material violation of the Company’s code of conduct; (vi) any material violation of the Company’s policies concerning harassment or discrimination; (vii) conduct that causes material harm to the business reputation of the Company or its Affiliates; or (viii) breach of the confidentiality, non-competition, or non-solicitation provisions of the change in control agreement. | | | “good reason” generally means (i) a material diminution in base salary or annual bonus opportunity; (ii) a material diminution in authority, duties, or responsibilities (including status, offices, titles and reporting requirements); (iii) a material change in the geographic location; (iv) the failure of the Company to pay compensation or benefits when due, or (v) any other action or inaction that constitutes a material breach by the Company of the change in control agreement. | | | “change in control” generally means any one of the following events: (a) any person becoming the beneficial owner of thirty percent (30%) or more of Company’s voting securities (other than as a result of certain issuances or open market purchases approved by incumbent directors); (b) the Company’s incumbent directors ceasing to constitute at least a majority of the board of directors; (c) the shareholders of the Company approving a reorganization, merger, consolidation, statutory share exchange or similar form of corporate transaction, or the sale or other disposition of all or substantially all of the Company’s assets, unless immediately following such transaction, (i) all or substantially all of the beneficial owners of the Company’s voting securities prior to such transaction are the beneficial owners of more than 50% of the combined voting power of the securities of the surviving entity in the transaction, (ii) no person is the beneficial owner of 30% or more of the combined voting power of the surviving entity in the transaction and (iii) at least a majority of the members of the board of directors of the surviving entity are incumbent directors; or (d) approval by the Company’s shareholders of a complete liquidation and dissolution of the Company. The preceding was a summary of the definition of a change in control, so please refer to actual text of the definition as set forth in the change in control agreements. |

    Long-Term Incentive Awards The award agreements under which our PRSU, RSU and stock option awards were issued describe the circumstances under which the awards will vest (or become non-forfeitable), if earlier than the stated date. The following is a general summary of the provisions applicable to the NEO awards that were unvested at December 31, 2024. Upon the death or disability of a participant, a prorated portion of the award will generally vest. Upon a termination without cause, a similar prorated portion of the award will generally vest. For time-based RSUs and stock options, a retiring participant is eligible to receive the full award on the original vesting timeline if the participant is at the time of retirement at least 55 years of age and has at least 10 years of service with the Company, subject to provision of a release to the Company and compliance with two-year noncompetition and non-solicitation covenants. For PRSUs, a prorated portion of the award remains outstanding upon retirement based on service over the applicable performance period. PRSUs that vest after retirement remain subject to actual performance results in case of termination without cause or retirement, and are vested at target in case of death or disability. Unvested awards are forfeited upon a termination with cause or voluntary resignation. In the case of a change in control, all awards are “double trigger” – if a change in control occurs, the award is continued or replaced with an award of comparable value, and the participant is subsequently terminated without cause within two years of the change in control, then the portion of the award that was unvested at the time of termination will be accelerated. If in connection with a change in control the award is not continued or replaced with an award of comparable value, then the unvested portion of the award would be accelerated upon the change in control without requiring termination of employment. PRSUs would vest at the greater of target level or estimated actual performance if otherwise payable upon a change in control. Under such long-term incentive award agreements, a “change in control” of the Company generally means, in accordance with Treasury Regulation Section 1.409A-3(i)(5), any of the following: (i) any one person, or more than one person acting as a group, acquires ownership of stock of the Company that, together with stock held by such person or group, constitutes more than 30% of the total voting power of the stock of the Company; (ii) a majority of members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election; (iii) any one person, or more than one person acting as a group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross

    fair market value equal to 50% of more of all of the assets of the Company immediately prior to such acquisition or acquisitions; or (iv) certain other business transactions affecting the Company. Post-Termination Table The table below shows an estimate of the amount of additional compensation that each of our NEOs would receive in the event of a termination or change in control, taking into consideration the circumstances of the termination and payments that the NEO would be entitled to under the various agreements described above. The amounts shown are generally categorized as follows: voluntary termination or termination for cause; involuntary termination without cause or by the executive for good reason; termination due to death or disability; qualified retirement (if eligible); and change in control (with and without termination). The amounts shown assume that such termination was effective as of December 31, 2024, and with reference to stock values on December 31, 2024. On December 31, 2024, the closing price of our Common Stock was $69.21 per share. The table below includes additional benefits triggered by a termination and change in control only. Please see the following tables for details of the NEOs’ vested payments and benefits that they would be entitled to receive regardless of the occurrence of a termination or change of control: •For PRSUs / RSUs / Stock Options – See “Outstanding Equity Awards at Fiscal 2024 Year-End Table”; •For Pension Benefits – See “2024 Pension Benefits Table”; and •For Nonqualified Deferred Compensation – See “2024 Nonqualified Deferred Compensation Table”. The actual amounts that will be paid upon termination can only be determined at the time of the NEO’s termination from the Company. The following table shows the potential payments to our NEOs upon termination or change in control. See below for additional information regarding Ms. Ryerkerk and Mr. Kelly’s separation agreements.

    (1)Reflects amounts that would be payable pursuant to our Executive Severance Benefits Plan and change in control agreements, as applicable as of December 31, 2024, and discussed above. (2)Stock Options vest in full upon a Change in Control if the award is not continued or replaced with an award of equivalent economic value. The numbers presented in the Change in Control scenarios assume that the awards are not continued or replaced with an award of equivalent economic value. To the extent the awards are continued or replaced with awards of equivalent economic value and the NEO remained employed following a Change in Control, the numbers shown in the Change in Control without termination column would be different. In the event of other eligible termination events, generally a prorated amount will vest based on the portion of the service period that has lapsed. For stock options, an eligible retiree would receive the full award on the original vesting timeline, subject to provision of a release to the Company and compliance with two-year noncompetition and non-solicitation covenants.

    (3)Time-based RSUs vest in full upon a Change in Control if the award is not continued or replaced with an award of equivalent economic value. The numbers presented in the Change in Control scenarios assume that the awards are not continued or replaced with an award of equivalent economic value. To the extent the awards are continued or replaced with awards of equivalent economic value and the NEO remained employed following a Change in Control, the numbers shown in the Change in Control without termination column would be different. In the event of other eligible termination events, generally a prorated amount will vest based on the portion of the service period that has lapsed. For time-based RSUs, an eligible retiree would receive the full award on the original vesting timeline, subject to provision of a release to the Company and compliance with two-year noncompetition and non-solicitation covenants. (4) Upon a Change in Control, PRSUs vest at the greater of target or estimated actual performance (target performance for 2022, 2023 and 2024 PRSUs has been assumed) if the award is not continued or replaced with an award of equivalent economic value. The numbers presented in the Change in Control scenarios assume that the awards are not continued or replaced with an award of equivalent economic value. To the extent the awards are continued or replaced with awards of equivalent economic value and the NEO remains employed following a Change in Control, the numbers shown in the Change in Control without termination column would be different. In the event of death or disability, a prorated amount of the unvested PRSUs would vest based on target performance. In the event the NEO is terminated without Cause, a prorated amount of the unvested PRSUs would remain outstanding and eligible to vest based on actual performance. In the event the NEO retires, a prorated amount of the unvested PRSUs would vest based on actual performance. (5) Represents reimbursement of premiums for 18 months of medical and dental coverage continuation upon a termination in connection with a change in control as applicable, and the payment of COBRA premiums for a period of one year from the date of termination under our Executive Severance Benefits Plan, each based on 2024 rates. (6) Upon termination by the Company without cause, each Executive would receive up to $16,200 in outplacement services. (7) The CIC Agreements provide for a “best net” feature which would reduce the parachute payments to the safe-harbor limit if it is more financially advantageous to the executive on an after-tax basis (taking into consideration federal, state and local income taxes, and the imposition of the excise tax). In the event it is more advantageous for the executive's payments to be reduced, the Company shall reduce or eliminate the payments by first reducing or eliminating those payments which are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order of when they would have otherwise been paid. Ms. Ryerkerk’s Separation Agreement. On December 9, 2024, the Board appointed Mr. Richardson as President and Chief Executive Officer, effective as of January 1, 2025, and determined to involuntarily terminate Ms. Ryerkerk, whose departure was effective as of December 31, 2024. The CMDC determined her separation was a termination without cause under the Severance Plan. On December 27, 2024, we entered into an agreement (the “Separation Agreement”) with Ms. Ryerkerk pursuant to which she ceased to serve as President and Chief Executive Officer effective December 31, 2024 and departed the Company on December 31, 2024. Under the Separation Agreement, subject to her continued compliance with certain restrictive covenants, Ms. Ryerkerk will receive severance benefits in accordance with the terms of the Severance Plan, as then in effect, including a severance payment of $6,750,000 and the 2024 bonus payment set forth in the “Non-Equity Incentive Plan Compensation” column of the “2024 Summary Compensation Table” above. Additionally, her outstanding time-based RSUs and stock options will remain outstanding and eligible to vest on the previously applicable vesting schedule, and a pro-rata portion of her outstanding PRSUs through her last day of service remains outstanding and eligible to vest based on attainment of the applicable performance goals over the relevant performance periods, in each case, in accordance with the retirement vesting provisions of the applicable award agreements (with an estimated aggregate value of approximately $6,361,735 based on our closing stock price on December 9, 2024, the date of the announcement of her departure, and assuming target performance for PRSUs). The Separation Agreement includes a customary waiver and release of claims and confidentiality and non-solicitation covenants in favor of the Company. Mr. Kelly’s Separation Agreement. On February 6, 2025, we entered into an agreement (the “Kelly Separation Agreement”) with Mr. Kelly pursuant to which he ceased serving as Senior Vice President, Engineered Materials, effective January 31, 2025, and was terminated without cause from the Company on March 10, 2025, following

  129. Potential Payments Upon Termination or Change In Control

    service in a transition role. The CMDC determined his separation was a termination without cause under the Severance Plan. Under the Kelly Separation Agreement, Mr. Kelly will receive severance benefits consistent with the terms of the Severance Plan, as amended, including a severance payment of $1,260,000 and the 2024 bonus payment set forth in the “Non-Equity Incentive Plan Compensation” column of the “2024 Summary Compensation Table” above. Additionally, his outstanding time-based RSUs vested on the previously applicable vesting date of February 15, 2025, prior to his termination, a pro-rata portion of his outstanding stock options vested on his separation date, and a pro-rata portion of his outstanding PRSUs through his last day of service remains outstanding and eligible to vest based on attainment of the applicable performance goals over the relevant performance periods, in each case, in accordance with the termination without cause vesting provisions of the award agreements (with an estimated aggregate value of approximately $323,182 based on our closing stock price on January 8, 2025, a trading day approximately one week prior to the announcement of his departure, and assuming target performance for PRSUs). The Kelly Separation Agreement includes a customary waiver and release of claims and confidentiality and non-solicitation covenants in favor of the Company.

  130. CEO Pay Ratio

    CEO Pay Ratio As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of SEC Regulation S-K, we are providing the following information about the relationship of the annual total

  131. CEO Pay Ratio

    | | Executive Compensation |

  132. CEO Pay Ratio

    compensation of our median-compensated employee and the annual total compensation of our CEO. For the year ended December 31, 2024: •the annual total compensation of our median-compensated employee, was $87,209; and •the annual total compensation of our CEO, as reported in the Summary Compensation Table presented elsewhere in this Proxy Statement, was $12,795,946. •based on this information, the ratio of the total compensation of our CEO to the annual total compensation of our median-compensated employee was 146.7 to 1. As permitted under SEC rules, we are electing to use the same median employee identified for our 2023 CEO pay ratio disclosure for the year ended December 31, 2024. Since November 1, 2023, there have been no changes in the Company’s employee population or employee compensation arrangements that we believe would significantly impact the pay ratio disclosure, nor has there been any change in such median employee’s circumstances that we believe would cause such median employee’s compensation to no longer be reflective of our median pay. We identified our median employee for 2023 using our employee population as of November 1, 2023. To identify our median employee, the methodology and the material assumptions, adjustments, and estimates that we used were as follows: •We selected November 1, 2023 as the date upon which we would identify the “median employee” to allow sufficient time to identify the median employee given the global scope of our operations. •We determined that, as of November 1, 2023, our employee population for pay ratio disclosure purposes consisted of approximately 12,403 individuals. We did not exclude any employees working outside of the U.S., and we did not use any statistical sampling techniques. •To identify the median employee from our employee population, we used actual salary payments reflected in our payroll records, which we believe is a reasonable method of identifying the median employee. The substantial majority of our employees do not participate in annual bonus or long-term incentive programs, therefore we believe that excluding those programs from consideration does not meaningfully impact the identification of the median employee. •In making these determinations, we annualized the compensation of all permanent employees who were hired in 2023 but did not work for us or our consolidated subsidiaries for the entire fiscal year. We did not make any cost-of-living adjustments in identifying the median employee. The CEO pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodologies and assumptions described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s total annual compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their compensation practices, which were chosen from a wide range of permissible methodologies, estimates and assumptions. As a result, the CEO pay ratios reported by other companies, which may have employed other permitted methodologies, exclusions, estimates or assumptions, and which may have a significantly different work force structure, geographic locations, or compensation practices from ours, are likely not comparable to our CEO pay ratio.

    (3)The dollar amounts reported represent the average of the amounts reported for the Company’s named executive officers (NEOs) as a group (excluding our CEO) in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs (excluding our CEO) included for purposes of calculating the average amounts in each applicable year are as follows: (i) for 2024, Mr. Richardson, Mr. Kyrish, Mr. Kelly and Mr. Murray; (ii) for 2023, Mr. Richardson, Mr. Kyrish, Mr. Kelly, Mr. Murray, Ashley B. Duffie, our Senior Vice President, General Counsel and Corporate Secretary, and Anne L. Puckett, our Former Senior Vice President, General Counsel and Corporate Secretary; (iii) for 2022, Mr. Richardson, Mr. Kelly, John G.

    (5)Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end of each applicable fiscal year and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period (December 31, 2019). (6)Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the Dow Jones (US) Chemical Index. (7)The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year. (8)The CMDC has selected Adjusted EPS as the Company-Selected Financial Measure representing the most important financial measure used to link performance to pay in 2024. Adjusted EPS is the most heavily-weighted metric in our PRSU design, and under our pay-for-performance approach PRSUs represent a significant portion of the NEOs’ compensation. Adjusted EPS is a non-U.S. GAAP financial measure. See “Exhibit A” for information concerning this measure including a definition and reconciliation to the most comparable U.S. GAAP financial measure. Financial Performance Measures The most important financial performance measures used by the Company to link executive “compensation actually paid” to the Company’s NEOs in 2024 to the Company’s performance are listed below. These metrics are further described in “Compensation Discussion and Analysis — Compensation Decisions — Annual Incentive Plan Awards” and “— Long Term Incentive Compensation.”

    Description of Certain Relationships of Information Presented in the Pay Versus Performance Table The Company uses several performance measures to align executive compensation with Company performance, which are described in “Compensation Discussion and Analysis — Compensation Philosophy and Elements of Pay” and “— Compensation Decisions”. Not all of these measures are presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and does not specifically align the Company’s performance measures with “compensation actually paid” (as computed in accordance with SEC rules) for a particular year. In accordance with SEC rules, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

    Total Shareholder Return: Company versus Peer Group (Dow Jones US Chemicals Index) and (2) "Compensation Actually Paid” versus Company Total Shareholder Return As shown in the chart below, the Company’s 5-year cumulative TSR is aligned to that of the companies included in our industry index, the Dow Jones US Chemicals Index. Our CEO and other NEOs’ “compensation actually paid” amounts are generally aligned with the trend in TSR performance, as shown in the chart below. This is primarily because “compensation actually paid” is significantly impacted by year-over-year changes in stock prices due to the significant portion of each NEO’s compensation that is equity-based.

  153. Pay Versus Performance

    “Compensation Actually Paid” versus GAAP Net Income and Adjusted EPS Like many companies, our sales and earnings in 2020 were significantly adversely affected by the COVID-19 pandemic. Our relatively high GAAP net income in 2020 was primarily due to a $1,408 million gain on the sale of our joint venture interest in Polyplastics Co. Ltd. that was completed in October 2020 (and which was excluded from the Adjusted EPS results for that year). Excluding the impact of this transaction, we believe our GAAP net income trend over the past five years is not misaligned to the trend in “compensation actually paid.” While the CMDC has selected Adjusted EPS as the Company-Selected Financial Measure representing the most important financial measure used to link performance to pay in 2024, the CMDC does not use GAAP net income to make decisions regarding compensation levels or design, or incentive plan payouts.
