  27. Elements of our Non-Executive Director Compensation Program

    Elements of our Non-Executive Director Compensation Program The table below sets out a summary of our non-executive director compensation for 2025. Our non-executive director compensation program for 2025 consisted of an annual cash retainer and an annual equity retainer in the form of RSUs (which vest on the earlier of (i) the first anniversary of the grant date and (ii) the date of the next annual general meeting of shareholders), as well as additional retainers and a grant of Pro Rata Awards, as noted below. As Mr. Stockton did not stand for election at the 2025 annual general meeting of shareholders, he did not receive the annual equity retainer.

  28. Elements of our Non-Executive Director Compensation Program

    | Annual Cash Retainer | $120,000 | | Annual Non-Executive Chair Cash Retainer (supplemental) | $100,000 | | Additional Annual Committee Retainers | | | Audit Committee Chair | $25,000 | | Compensation Committee Chair | $20,000 | | Nomination Committee Chair | $20,000 | | Sustainability Committee Chair | $20,000 | | Finance Committee Chair | $20,000 | | Annual Stock Grant | $175,000 | | Annual Non-Executive Chair Stock Grant (supplemental) | $100,000 |

  29. Elements of our Non-Executive Director Compensation Program

    In addition to the annual compensation set forth in the above table, for 2025 only, the Board approved grants of RSUs to each non-executive director (including Mr. Stockton, who served as a director until the 2025 annual general meeting of shareholders) in respect of the period between January 1, 2025, and the 2025 annual general meeting of shareholders (the “Pro Rata Awards”). The Pro Rata Awards were made in connection with the alignment of our non-executive director equity grant timing from calendar year-based grants in 2024 to grants aligned with our annual general meeting of shareholders starting in 2025, which we view to be consistent with market practices. Accordingly, on March 4, 2025, the Board approved grants of 1,332 RSUs to each non-executive director and 2,093 RSUs to the Chair. The Pro Rata Awards vested on May 1, 2025, immediately prior to our 2025 annual general meeting of shareholders. To further align the long-term interests of our directors and our shareholders, we maintain the Smurfit Westrock Share Ownership Policy, which requires each non-executive director to hold shares having an aggregate value equal to five times the annual cash base retainer. In addition to shares held by the non-executive director, an immediate family member or in a trust for the benefit of the non-executive director, shares underlying vested but deferred RSUs and shares underlying time-based RSUs are considered for purposes of complying with the guidelines. No stock options or unearned performance-based awards (if applicable) are considered. Until the applicable non-executive director has achieved the requisite ownership guideline, the non-executive director must retain 50% of the post-tax shares received upon vesting, settlement, or exercise of any equity award granted by the Company. As of the end of 2025, all of our non-executive directors were either in compliance with the requisite ownership guideline or subject to the holding policy, as applicable. In 2025, we did not provide any compensation or benefits to our non-executive directors other than the fees and stock awards described above and reimbursement of reasonable travel and other expenses incurred in connection with attending meetings of the Board and its committees.

  43. Executive Summary

    | Financial Results | Pay for Performance | | ● Despite difficult market conditions, we delivered strong results in 2025, achieving $31.2 billion in full‑year net sales and generating $0.7 billion in net income and net income margin of 2.2%. We achieved $4.9 billion Adjusted EBITDA with an Adjusted EBITDA margin of 15.8% for the year. The company also generated net cash provided by operating activities of $3.4 billion and more than $1.5 billion in Adjusted Free Cash Flow (“Adjusted FCF”), reflecting robust cash generation across the business. | ● Executive pay remained strongly performance-oriented, with approximately 90% of the CEO’s target compensation and approximately 80% (on average) of other NEOs’ target compensation at risk, and long-term incentives delivered primarily through performance-based equity awards (75% PSUs / 25% RSUs). | | Synergy Realization | Aligned Compensation Program | | ● Achieved over $400 million synergies by the end of 2025, surpassing the original target through cost efficiencies, operational streamlining, and exiting loss‑making capacity. This outcome demonstrates exemplary execution of integration priorities and reflects the transformational impact of the Company’s first full year post‑Combination. | ● The Compensation Committee continued to embed and administer our compensation program to ensure alignment with our strategy and the creation of shareholder value, with incentive plans that the Compensation Committee considers to directly reflect the most critical financial and strategic outcomes underpinning that strategy. The Compensation Committee maintained competitive pay levels informed by a 17‑company peer group, supported by strong shareholder backing in the say‑on‑pay vote, and upheld by strong governance practices, including robust stock ownership guidelines and clawback policies. |

    Base Salary Base salaries provide for a fixed level of total compensation that is determined by taking into account the applicable NEO’s experience and job scope as well as compensation levels of similarly-situated executive officers of our Compensation Peer Group (described in greater detail under the heading “Our Compensation Decision-Making Process — Compensation Peer Group”). The NEOs’ base salaries remained unchanged between 2024 and 2025. The USD values of the base salaries for those NEOs who are paid in Euros (Messrs. Smurfit, Bowles and Mayer) as reported in the table below appear higher for 2025 than the respective NEOs’ 2024 base salaries reported in the corresponding section of the Compensation Discussion and Analysis of our proxy statement for the 2025 annual general meeting of the shareholders of Smurfit Westrock because the NEO’s base salaries are set in local currency and, as such, this presentation of the base salary amounts is affected by inter year exchange rate fluctuations between 2024 and 2025.

  58. 2025 Annual Incentive Design

    For 2025, the Compensation Committee approved the following performance metrics under the AIP, with the following relative weightings: Our Compensation Committee believes that these performance metrics were appropriate for 2025, with 80% of our 2025 AIP goals measuring the following financial performance metrics: Adjusted EBITDA (our core operations excluding non-recurring or non-operational items), Free Cash Flow (our ability to generate cash to fund operations and key business investments) and Synergies (our ability to achieve the synergy targets agreed with our Board by 2025 fiscal year-end) and 20% of our 2025 AIP goals measuring strategic goals such as Health and Safety and Other Strategic Priorities. For Messrs. Sellier and Mayer, the Adjusted EBITDA performance metric is divided between Adjusted Group EBITDA (weighed as 15% of the AIP opportunity) and Regional EBITDA (weighted as 20% of the AIP opportunity) and the Health and Safety performance metric is based on their respective regions, which aligns these NEOs’ compensation to the performance of the respective regions for which these NEOs are primarily responsible.

    | | 55 | 2026 PROXY STATEMENT |

  60. 2025 Annual Incentive Design

    | Weighting | Metric | Rationale for the Metric | | | Adjusted EBITDA | Adjusted EBITDA offers a focused view of our core performance by adjusting for one‑off or non‑operational items, helping ensure that this AIP metric rewards sustainable value creation. | | | Free Cash Flow | Free Cash Flow directly reflects the Company’s ability to generate cash and create tangible, sustainable value for shareholders. | | | Synergies | Synergies reward the delivery of shareholder committed integration benefits that enhance efficiency, reduce costs, and accelerate value creation. | | | Health and Safety (“TRIR”) | Health and safety (“TRIR”) reinforces our strong safety culture and prioritizes the wellbeing of our employees as a core driver of sustainable performance. | | | Other Strategic Priorities | These measures encourage responsible practices that emphasize achievement of key sustainability goals, workforce engagement, community impact and culture and talent development as drivers of our long‑term success. |

  61. 2025 Annual Incentive Design

    For purposes of the 2025 AIP:

  62. 2025 Annual Incentive Design

    | ● | Adjusted EBITDA is determined as net income before income tax expense, depreciation, depletion and amortization, interest expense, net, pension and other postretirement non-service income (expense), net, share-based compensation expense, other expense, net, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business; |

  63. 2025 Annual Incentive Design

    | ● | Free Cash Flow is determined as net cash provided by operating activities as adjusted for capital expenditures; |

  64. 2025 Annual Incentive Design

    | ● | Synergies is determined as the incremental Adjusted EBITDA reported from synergy and integration initiatives in 2025, relative to the amount reported in 2024. It includes the financial benefits delivered through actions such as cost reductions, procurement savings, overhead efficiencies, and operational improvements taken in both 2024 and 2025, with the full year Adjusted EBITDA impact of the former, less that reported already in 2024, and the proportional Adjusted EBITDA impact from the latter, depending on the time of its implementation; |

  65. 2025 Annual Incentive Design

    | ● | Health and Safety (“TRIR”) is determined as the total number of recordable injury cases per 200,000 hours worked by all employees. This is calculated by dividing the total number of recordable injury cases by the total hours worked by all employees during the period, multiplied by 200,000. The total number of recordable injury cases is defined as the total lost time accidents, restricted workday cases and medical treatment cases; and, |

  66. 2025 Annual Incentive Design

    | ● | Other Strategic Priorities included issuing the first Smurfit Westrock Task Force on Climate‑Related Financial Disclosures (“TCFD”) disclosures; enhancing workforce engagement through a global employee survey; implementing a comprehensive workforce talent and culture strategy; publishing key sustainability key performance indicators (“KPIs”); and advancing the Smurfit Westrock Foundation’s social impact strategy with a $5 million community investment. |

    Long-Term Incentive Plan

  78. Summary

    Summary Our Compensation Committee grants annual equity awards under the Smurfit Westrock plc 2024 Long-Term Incentive Plan (“LTIP”), consisting primarily of performance-based awards, with PSUs representing 75% of the grant date value for each NEO and RSUs representing the remaining 25% of the grant date value for each NEO. The LTIP is the only plan under which we grant equity awards. During 2025, we did not grant stock options or stock option-like awards. Further, during 2025, the Compensation Committee did not take material non-public information into account when determining the timing and terms of equity incentive awards, and we did not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation.

  79. 2025 Long-Term Incentive Awards

    2025 Long-Term Incentive Awards Our Compensation Committee approved a target long-term incentive opportunity for each of our NEOs, informed by their review of long-term incentive opportunities in our Compensation Peer Group and intended to reflect our U.S. listed status and geographical and industry footprint, to align pay to performance, and to motivate our executives to execute a significant multi-year integration for long-term success. In determining the target annual long-term incentive opportunity for each of the NEOs, the Compensation Committee considered each executive’s level of responsibility and experience, the executive’s overall target total direct compensation, and market-competitive compensation aligned with the companies in our Compensation Peer Group. The Target LTIP opportunity for Mr. Sellier and Mr. Mayer increased by $1,000,000 and $500,000, respectively, in 2025, as approved by the Compensation Committee, to adjust for market competitiveness. The target long-term incentive opportunity for each of our NEOs, which will be delivered in the form of PSUs (representing 75% of the grant date value for each NEO) and RSUs (representing the remaining 25% of the grant date value for each NEO), was based on a performance period commencing on and including January 1, 2025, and ending December 31, 2027 (the “Performance Period”).

    | | 58 | 2026 PROXY STATEMENT |

  83. 2025 Long-Term Incentive Awards

    | For 2025, the Compensation Committee approved the following performance metrics for the 2025-2027 PSUs, with the following relative weightings: | |

  84. 2025 Long-Term Incentive Awards

    | Metric | Rationale for the Metric | | Relative TSR | rTSR directly links rewards to shareholders’ long‑term value by measuring performance against market peers | | Adjusted Cumulative EPS | Adjusted cumulative EPS rewards sustained growth in underlying earnings, reinforcing long‑term profitability and value creation | | Average ROCE | Return on capital employed rewards efficient use of invested capital to drive sustained, high‑quality returns over the long term |

  85. 2025 Long-Term Incentive Awards

    PSUs will be eligible to vest from 0% to 200% of the target number of PSUs granted based on achievement of the performance metrics described above over the Performance Period. Threshold performance will yield a 50% payout; target performance will yield a 100% payout and maximum performance will yield a 200% payout. Straight‑line interpolation will be applied for any percentile result between threshold, target and maximum levels of performance. For purposes of the 2025 LTIP:

  86. 2025 Long-Term Incentive Awards

    | ● | Relative TSR (“rTSR”) is relative to the total shareholder return of companies in the S&P 500 at the start of the performance period. rTSR is determined as the average of the closing price of shares during the 20 consecutive trading days ending on the last trading day of the performance period, minus the average of the closing price of shares during the 20 consecutive trading days beginning with the first trading day during the performance period (the “beginning stock price”) plus dividends paid during the performance period (deemed reinvested in the underlying shares), divided by the beginning stock price; |

  87. 2025 Long-Term Incentive Awards

    | ● | Adjusted Cumulative EPS is determined as the sum of the Company’s basic earnings per share attributable to common shareholders (as reported in the Company’s Annual Report for the applicable year), adjusted to exclude the cost of items that management believes are not indicative of the operating results of the business, for each completed calendar year during the Performance Period. The Committee shall have the right to adjust Cumulative Adjusted EPS to exclude certain non-recurring items, as shall be determined from time to time; and |

  88. 2025 Long-Term Incentive Awards

    | ● | Average ROCE is calculated as the Company’s ROCE for each year in the Performance Period, divided by three. ROCE is defined as segment adjusted EBITDA, further adjusted for unallocated corporate costs, depreciation, depletion and amortization, share‑based compensation, and other expense (income) excluding finance costs or income, divided by average capital employed. Capital employed is total equity plus current and non‑current debt, minus cash and cash equivalents. Average capital employed is the average of capital employed for the year and the preceding year. The Committee may adjust ROCE to exclude certain non‑recurring items. |

    Other Compensation

  91. Service Contracts, Offer Letters and Post-Termination Compensation

    Service Contracts, Offer Letters and Post-Termination Compensation Each of our NEOs has entered into a service contract or offer letter with the Company. In addition, we maintain the Smurfit Westrock plc Executive Severance Plan (the “Executive Severance Plan”). Each of the NEOs other than Mr. Garren are eligible participants in the Executive Severance Plan. Mr. Garren will not be eligible to participate in the Executive Severance Plan and will instead be eligible to receive severance payments pursuant to his offer letter with the Company. The service contracts and offer letters, and the key terms of the Executive Severance Plan, are described further under “Potential Payments upon Termination or Change in Control,” below. Our service contracts and offer letters with our NEOs and the Executive Severance Plan do not include guaranteed bonus amounts, “golden parachutes,” significant accelerated vesting of equity incentive awards or payments triggered solely by a change in control (i.e., no “single-trigger” payments), U.S. Internal Revenue Code section 280G or other excise tax gross-up payments related to a change in control, other than as may be required by local law. Consistent with our compensation philosophy, our NEOs’ compensation is tied to the NEOs’ own performance and the Company’s performance, rather than to long-term fixed employment agreements.

  92. 2025 Limited Perquisites and Other Benefits

    2025 Limited Perquisites and Other Benefits In 2025, we provided our NEOs certain limited perquisites as a feature for executive retention and recruitment, which are intended to be consistent with benefits typically offered in the respective regions where the NEOs are located, and are intended to be similar in scope and value to those offered by companies in our Compensation Peer Group. Each of our NEOs, other than Mr. Garren, is provided with a car benefit, either in the form of a car allowance or a company provided vehicle, which is a typical benefit within our Compensation Peer Group in the respective regions where these NEOs are located. In 2025, Mr. Bowles received reimbursements in respect of two professional subscriptions. In addition, under their service contracts, Messrs. Smurfit and Bowles are entitled to certain benefits that are typical within their Compensation Peer Group in the region(s) in which they are located and that are in part due to the fact that they are not eligible to participate in certain customary employee benefit plans (for example, a private group medical program) that are not currently offered in their region(s). Accordingly, Messrs. Smurfit and Bowles receive a cash allowance in lieu of employer pension contributions at a rate of 10% of their respective base salaries and an annual cash allowance of $10,000 each (paid in Euros at the applicable exchange rate), with the euro‑denominated amount having been set in 2025, to cover private group medical costs. Our NEOs generally participate in the same retirement, health, welfare and other benefits programs broadly available to salaried employees in the relevant regions, subject to eligibility criteria. Messrs. Sellier, Mayer, and Garren are also eligible to participate in the defined contribution retirement plan applicable to their respective regions and receive a Company match in accordance with the terms of the applicable plan. In addition, Mr. Garren received limited travel benefits in the form of personal spousal travel; Messrs. Smurfit and Bowles have received customary corporate gifts of limited value; and each of our NEOs is eligible for an executive physical, financial and tax planning services, executive life insurance coverage and long-term disability coverage, each of which benefits we view as being generally consistent with benefits provided by members of our Compensation Peer Group. The footnotes to the “Summary Compensation Table” provide additional detail regarding the applicable perquisites and other relevant benefits provided to our NEOs in 2025. We do not provide our NEOs with excise tax gross-ups for any payments in connection with a change in control.

  93. 2025 Limited Perquisites and Other Benefits

    In addition to shares held by the executive officer, an immediate family member or in a trust for the benefit of the executive officer, unvested time-based RSUs are considered for purposes of complying with the guidelines. No stock options or unearned performance-based awards are considered. Until the applicable executive officer has achieved the requisite ownership guideline, the executive officer must retain 50% of the post-tax shares received upon vesting, settlement, or exercise of any equity award granted by the Company. Clawback Policies We maintain a Dodd-Frank Clawback Policy consistent with the requirements of the SEC and NYSE (the “Clawback Policy”). In the event we were required to prepare an accounting restatement of our financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, we would recover the excess incentive-based compensation received by any covered executive, including the NEOs, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements. If and as required, we intend to make disclosures with respect to our Clawback Policy and its application in a manner consistent with the requirements of the SEC and NYSE. Additionally, in order to encourage sound financial reporting and enhance individual accountability, we maintain a discretionary clawback policy for our current and former executive officers, direct reports to the President & Group Chief Executive Officer and any other employee of the Company designated by the Compensation Committee from time to time. The discretionary clawback policy provides that, we may seek to recover or cancel any cash- or non-cash incentive compensation (including compensation subject to time-based vesting only) earned, granted, vested, paid or otherwise received to or by the applicable covered person during the three-year period preceding the date of the Compensation Committee’s determination of an applicable “triggering event”. For purposes of the discretionary clawback policy, a “triggering event” is generally defined as (i) a willful violation of applicable federal, state or local law or Company policy, (ii) an act of fraud, breach of fiduciary duty, material act of dishonesty, material misrepresentation, gross negligence or other act of willful misconduct, act that results in material reputational, financial or operational harm to the Company, or evidence or problematic decisions or actions or material risk management failure, or (iii) any restatement of the Company’s financial statements or similar revision of performance indicators upon which the applicable covered compensation was based, where such restatement was due to such covered person’s conduct or failure to act.

  94. Summary Compensation Table

    Summary Compensation Table This table contains information about the compensation paid to or earned by each of our NEOs during 2025, 2024 and 2023, as applicable.

  140. Pay Versus Performance

    | (1) The dollar amount reported in this column represents the total compensation reported for Mr. Smurfit, our PEO, for 2024 and 2025 in our Summary Compensation Table. Refer to the “Executive Compensation Tables — Summary Compensation Table.” |

  141. Pay Versus Performance

    | (2) The dollar amount reported in this column represents the average of the total compensation reported for our Non-PEO NEOs for each applicable year in our Summary Compensation Table. The Non-PEO NEOs for 2024 were Ken Bowles, Saverio Mayer, Laurent Sellier, and Ben Garren. The Non-PEO NEOs for 2025 were Ken Bowles, Saverio Mayer, Laurent Sellier, and Ben Garren. |

  142. Pay Versus Performance

    | (3) The dollar amounts reported in these columns represent the amount of “compensation actually paid” (“CAP”) to our PEO and the average compensation actually paid to our Non-PEO NEOs, as computed in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually realized or received by such individuals. In accordance with these rules, these amounts reflect the total compensation for our PEO, and the average total compensation for our Non-PEO NEOs, as set forth in the Summary Compensation Table for 2025, adjusted as shown below. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. For the Non-PEO NEOs, the amounts set forth below are averages for all of the Non-PEO NEOs as a group. |

  144. Pay Versus Performance

    | (4) Total Shareholder Return (“TSR”) is calculated by dividing (a) the sum of (i) the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and (ii) the difference between the share price at the end of each fiscal year and the beginning of the measurement period, by (b) the share price at the beginning of the measurement period. The beginning of the measurement period for purposes of determining the Company’s TSR and the peer group TSR is July 8, 2024. |

  145. Pay Versus Performance

    | (5) The peer group used for purposes of determining the TSR of our peer group is the Dow Jones U.S. Containers & Packaging Index. |

  146. Pay Versus Performance

    | (6) The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for each fiscal year. |

  147. Pay Versus Performance

    | (7) We determined Adjusted EBITDA to be the most important financial performance measure used to link our performance to “compensation actually paid” to our PEO and Non-PEO NEOs following the Combination. Adjusted EBITDA is a non-GAAP financial measure. For this purpose, Adjusted EBITDA is determined as net income before income tax expense, depreciation, depletion and amortization, interest expense, net, pension and other postretirement non-service income (expense), net, share-based compensation expense, other expense, net, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business |

    Description of Certain Relationships between Information Presented in the Pay versus Performance Table As described in more detail in the section “Executive Compensation — Compensation Discussion and Analysis,” our executive compensation program reflects a variable pay-for-performance philosophy. While we utilize financial performance measures to align executive compensation with Company performance, they are not all required to be presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s financial 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 above.

  150. Compensation Actually Paid, Cumulative TSR and Peer Group TSR

    Compensation Actually Paid, Cumulative TSR and Peer Group TSR Our TSR decreased by 11.8% from December 31, 2024 (the last trading day of the fiscal year 2024) through the end of 2025. The decrease in our TSR is in line with the 3.3% decrease in the Dow Jones U.S. Containers & Packaging Index over the same period. The decrease in our TSR from the Combination is the primary reason that the 2025 CAP to our PEO of ($726,562) is lower than the Summary Compensation Table figure of $16,429,689, and that the average CAP for our Non-PEO NEOs of $1,729,745 is lower than the Summary Compensation Table average of $5,279,852.

  151. Compensation Actually Paid and Financial Performance Measures

    Compensation Actually Paid and Financial Performance Measures Since we became a newly U.S. listed, Irish public company on July 8, 2024, at this time there is no clear correlation between compensation actually paid, net income, and adjusted EBITDA. We believe the compensation actually paid to our PEO and Non-PEO NEOs in 2025 reflects our pay-for-performance philosophy, and this relationship will develop as we build history as a newly U.S. listed, Irish public company. Financial Performance Measures The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs for the most recently completed fiscal year to the Company’s performance are as follows:

  158. CEO PAY RATIO

    CEO PAY RATIO Pursuant to the pay ratio disclosure requirement under Item 402 of Regulation S‑K, we provide the following information comparing the annual total compensation of our CEO to that of our median employee (excluding our CEO), together with a description of the methodology used to identify the median employee and calculate the respective compensation amounts. For 2025, the annual total compensation of our median employee (excluding our CEO) was $60,554, while the annual total compensation as presented in the “Total” column in the 2025 Summary Compensation Table for our CEO was $16,429,689. As a result, for 2025, the ratio of the annual total compensation of our CEO to that of our median employee was estimated to be 271 to 1. Methodology Our CEO pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules. Our methodology and process is explained below:

  159. CEO PAY RATIO

    | ● | Determined employee population. We began with our global employee population (excluding our CEO) as of October 1, 2025 (the “Determination Date”). As of that date, we had approximately 95,797 full-time, part-time, and seasonal or temporary workers, employed by the Company, consisting of 31,860 U.S. employees and 63,937 non-U.S employees. Pursuant to the de minimis exemption allowed by the SEC, we then excluded 4,614 non-U.S. employees located in certain countries, which represented in aggregate less than 5% of our total population (Austria (572), Bulgaria (299), Greece (202), Hungary (38), Latvia (5), Lithuania (112), Monaco (1), Morocco (135), Norway (190), Portugal (187), Slovakia (210), South Africa (1), Switzerland (199), Australia (212), India (408), Japan (52), Malaysia (6), New Zealand (3), Singapore (1), South Korea (20), Taiwan (6), Thailand (10), Vietnam (3), Chile (211), Costa Rica (362), Dominican Republic (467), Ecuador (88), El Salvador (344), Guatemala (7), Honduras (4), Nicaragua (13), and Peru (246)). After excluding the countries and employees described above, we determined the identity of our median employee from a population of 91,183 employees, including 31,860 U.S. employees and 59,323 non-U.S. employees. |

  160. CEO PAY RATIO

    | ● | Identified the median employee. We used a consistently applied compensation measure across the employee population determined as described above to calculate the median employee. We did not make any cost-of-living adjustments. The consistently applied compensation measure we used was annualized base salary, which we believe is a compensation measure that can be applied consistently across our employee population. Annualized base salary for salaried employees consisted of the base rate effective on October 1, 2025, and for hourly employees consisted of the annualized base rate, using the hourly rate effective on October 1, 2025, and standard annual work hours. |

  161. CEO PAY RATIO

    | ● | Calculated CEO pay ratio. We calculated our median employee’s annual total compensation for 2025 according to the SEC’s instructions for preparing the Summary Compensation Table as detailed in Item 402(c)(2)(x) of Regulation S-K. We then calculated our CEO’s annual total compensation using the same approach to determine the pay ratio shown above as of the Determination Date. |

  162. CEO PAY RATIO

    Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total 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, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.
