  4. Total Shareholder Return(1)

    Variable Compensation is Critical to Achieve Our Objectives (Page 53) Merck’s compensation programs are designed to align the interests of our executives with the interests of our shareholders, among other objectives. For this reason, a significant portion of our NEOs’ pay is variable and at-risk, subject to Company performance as measured against financial, operating and strategic objectives, as well as Relative Total Shareholder Return or R-TSR (as defined in Appendix B). The Company’s variable incentives continue to demonstrate a strong linkage between pay and performance. Annual Cash Incentive The Company Scorecard (described in more detail on page 55) focuses on our most critical business drivers — the Company’s revenue (“Revenue”), non-GAAP pre-tax income (“Pre-Tax Income”), the Company’s research and development goals (“Pipeline”), and the Company’s focus on driving greater access to health for patients around the world and on the engagement and inclusion of our employees (“Sustainability”) — and is used to determine the payout of our annual incentive for most employees, including our NEOs under the Executive Incentive Plan. Our Company Scorecard performance during 2023 resulted in above-target achievement of 148%.

  5. Total Shareholder Return(1)

    Long-Term Incentive (“LTI”) The long-term incentive program, consisting of a mix of Performance Share Units (“PSUs”) and stock options, provides our NEOs with the opportunity to own Merck common stock, directly linking a substantial portion of their compensation to the returns realized by our shareholders. The 2021 PSU program (described in more detail on page 58) paid out at 161% based on achievement of one-year Earnings Per Share (“EPS”) and three-year R-TSR metrics during the performance period (2021-2023), weighted at 33% and 67%, respectively. As previously disclosed, one-year EPS was used due to the complexities associated with disentangling our Organon & Co. (“Organon”) business from a multi-year financial plan. Organon was successfully spun off in June 2021.

    | Proposal 1 Election of Directors | | | | | | 35 |

  22. Total Shareholder Return(1)

    The Board has recommended 12 nominees for election as Directors at the 2024 Annual Meeting: Mr. Douglas M. Baker, Jr., Ms. Mary Ellen Coe, Ms. Pamela J. Craig, Mr. Robert M. Davis, Mr. Thomas H. Glocer, Dr. Risa J. Lavizzo-Mourey, Dr. Stephen L. Mayo, Dr. Paul B. Rothman, Ms. Patricia F. Russo, Dr. Christine E. Seidman, Mr. Inge G. Thulin, and Ms. Kathy J. Warden. All nominees, other than Mr. Davis, our Chairman and Chief Executive Officer, satisfy the NYSE independence requirements. Mr. Peter Wendell will be retiring from the Board effective as of the 2024 Annual Meeting. Mr. Wendell has a distinguished history of insightful contributions since joining the Board in 2003, and the Board has benefited from his extensive management, financial and venture capital expertise. All Director nominees currently serve on the Board and were elected by the shareholders at the 2023 Annual Meeting of Shareholders. In addition, all Director nominees meet the Board’s criteria for membership and were recommended by the Governance Committee, and approved by the Board, for election by shareholders at the 2024 Annual Meeting. All of them hold, or have held, senior leadership positions in large, complex organizations, including multi-national corporations, medical or academic institutions, or charitable organizations. In these positions, our Director nominees have demonstrated their leadership, intellect and analytical skills and gained deep experience in core disciplines significant to their oversight responsibilities at the Company. Their varied roles and experiences reflect a diversity of perspectives, skills and expertise to address the Company’s current and anticipated needs as the Company’s opportunities and challenges evolve. If elected, each nominee will serve until the 2025 Annual Meeting of Shareholders or until a successor has been duly elected and qualified, subject to their earlier resignation, death or removal. Any Director nominee who does not receive a majority of the votes cast with respect to his or her election will not be re-elected as a Director of the Company. However, under the New Jersey Business Corporation Act, incumbent Directors who are not re-elected in an uncontested election because of a failure to receive a majority of the votes cast in favor of their re-election will be “held over” and continue as Directors of the Company until they resign, or their successors are elected at the next election of directors. Our Incumbent Director Resignation Policy, included in the Policies of the Board, provides that an incumbent Director who is not re-elected must promptly submit a resignation. The Governance Committee will evaluate whether to accept such resignation and make a recommendation to the full Board. The Board must act on the recommendation no later than 90 days following certification of the shareholder vote and publicly disclose its decision and rationale. If any Director nominee becomes unavailable for election (which we do not expect), votes will be cast for such substitute Director nominee or nominees as may be designated by the Board, unless the Board reduces its size. There are no family relationships among the Company’s executive officers and Directors. We provide below biographical information for each Director nominee, including key experience, qualifications and skills such Director nominee contributes to the Board in light of our current needs and business priorities.

    Changes to Non-Employee Director Compensation Program effective 2024 The Governance Committee reviews the Company’s non-employee Director compensation program on a biennial basis. In 2023, the Governance Committee conducted such a review in consultation with FW Cook, the C&MD Committee’s independent compensation consultant. The review included FW Cook’s analysis of both compensation levels and program design compared to Merck’s peer groups that are used for executive compensation competitive benchmarking—a U.S. pharmaceutical peer group and a supplemental peer group comprised of the Dow Jones Industrial Average companies, excluding financial services companies (as described on page 49). Based on this review and the recommendation of FW Cook, the Governance Committee submitted its findings to the full Board in November 2023 and recommended that the full Board approve changes to the non-employee Director compensation program to better align leadership position retainers with external peer companies prior to the Governance Committee’s biennial Director compensation program review in 2025. Based on the results of FW Cook’s analysis and the Governance Committee’s recommendation, the Board approved the following changes to the non-employee Director compensation program effective April 1, 2024:

With having completed the spin-off in 2021 as planned, we reverted to a three-year cumulative EPS and R-TSR design beginning with the 2022 PSU program, with 50% tied to EPS and 50% tied to R-TSR (described in more detail on pages 57-58). |

    Peer Groups Merck’s Primary Peer Group Individual executive officer compensation levels and opportunities are compared to a peer group of large multinational pharmaceutical companies approved by the C&MD Committee that participate in a pharmaceutical industry compensation survey conducted by Willis Towers Watson, an independent consulting firm. In setting compensation levels for 2023, the C&MD Committee reviewed the survey results for the following peer companies that Merck competes with to attract talented, high-performing executives (the “primary peer group”). The C&MD Committee regularly reviews segmented information focused on the companies in the primary peer group that are headquartered in the U.S. because practices outside the U.S. can differ geographically.

    Merck’s Supplemental Peer Group In addition to the primary peer group described above, we also use a supplemental peer group consisting of the companies that comprise the Dow Jones Industrial Average (excluding the financial services companies) as a secondary reference for CEO compensation and for other compensation-related practices (for example, share usage and dilution, change in control policy design, and stock ownership and retention guidelines). Merck is a member of the Dow Jones Industrial Average, and we believe this group provides insight into practices among companies of similar scale and complexity that operate across a variety of industries, providing us with a broader view of market pay, policies, and practices.

    2023 Company Scorecard Our Company Scorecard helps translate our strategic priorities into operational terms that enable tracking and measurement of our progress and performance against annual operating goals and critically important strategic drivers of long-term value creation, including goals tied to our research and development pipeline — each of which is measured in the context of compliance, health, safety, and environmental outcomes. The Company Scorecard may be adjusted based on an evaluation of these outcomes, recognizing the importance they play in driving Merck’s values and a culture of integrity. For 2023, no such adjustment was applied. We believe creating greater accountability for the sustainable delivery of business goals will help drive financial results and long-term shareholder value. As a result, the C&MD Committee approved a new measure in our 2023 Company Scorecard that links the compensation of most employees, including our executives, to certain Sustainability metrics. The new design reflects our focus on driving greater access to health to patients around the world and on the engagement and inclusion of our employees, each of which is a strategic priority. Revenue and Pre-Tax Income are equally weighted at 35% (previously 40%), each based on the C&MD Committee’s belief that they are the key financial measures of our success during the year. The Pipeline goals are collectively weighted at 20% and are designed to ensure we are focused on internal and external early discovery opportunities, late-stage clinical development progression, and regulatory filings and approvals. Finally, our new Sustainability metrics are collectively weighted at 10%. The target, threshold, and maximum Revenue and Pre-Tax Income goals are set in relation to the Board-approved annual operating plan and the expectations of management. Each year, the Pipeline goals are recommended by the President of Merck Research Laboratories, reviewed by the Research Committee, and approved by the C&MD Committee. The Sustainability metrics are recommended by Merck’s Global Market Access, ESG, and Human Resources teams and approved by the C&MD Committee. Failure to achieve threshold performance on any of the metrics would result in forfeiture of the entire opportunity for that metric. If the combined results of the four metrics do not total at least 50, there would be no payout. The overall results of the Company Scorecard are calibrated so individuals may receive between 50% and 200% of their target award opportunity established for the annual performance period. Adjustments are applied to Revenue and Pre-Tax Income results using a consistent framework of adjustments to our reported financial results for incentive program purposes approved by the C&MD Committee to accurately reflect the operating performance of our business. For further explanation of these adjustments, please refer to Appendix B on page 106. The 2023 Company Scorecard results are summarized below. 2023 Company Scorecard(1)

Pre-Tax Income: Non-GAAP pre-tax income of $5.99B was adjusted to $22.52B to exclude the effect of certain business development transactions as well as the impact of currency exchange rates (versus currency exchange rates budgeted in the annual operating plan) and the associated impact of hyper-inflation in certain markets (all consistent with plan design).

    Long-Term Equity Incentives The long-term incentive program, consisting of a mix of PSUs and stock options, provides our NEOs with the opportunity to own Merck common stock, directly linking a substantial portion of their compensation to the returns realized by our shareholders. We use these two vehicles to ensure that our LTI program remains balanced, sustainable, and supportive of its objectives over a multi-year period. 2023 Equity Award Mix

The earned award varies based on results versus pre-determined performance goals, as well as long-term returns to shareholders as measured by relative stock price performance and dividend yield. | | | Stock Options Stock options align our executives’ interests with the interests of our shareholders because options only have financial value to the recipient if the price of our common stock at the time of exercise exceeds the stock price on the date of grant. As a result, we believe stock option grants encourage executives to focus on behaviors and initiatives that support sustained long-term stock price appreciation, which benefits all shareholders. |

    Current LTI Grant Practices All grants to executive officers are made under the Merck & Co., Inc. 2019 Stock Incentive Plan and approved by the C&MD Committee and, in the case of our CEO, recommended by the C&MD Committee and approved by the independent members of the Board of Directors. Annual PSU grants (with a three-year performance period) are generally made on the last business day in March and annual stock option grants are made on the third business day following the announcement of

  89. Total Shareholder Return(1)

    our first quarter earnings. We may also selectively grant PSUs, stock options, and RSUs to executive officers on the third business day following the announcement of quarterly earnings generally as part of a new hire sign-on or for retention purposes. These dates were chosen to ensure that grants are made shortly after we have released information about our financial performance to the public. However, the C&MD Committee reserves the right to change the date when grants are made, in view of its responsibility to consider all facts and circumstances to ensure that grants are consistent with our compensation philosophy and objectives. Stock options are granted at no less than fair market value on a fixed date or date of a particular event, with all required approvals obtained in advance of or on the actual grant date. Fair market value is the closing price of a share of Merck common stock on the grant date. The re-pricing of stock options is not permitted under the Incentive Stock Plan without prior shareholder approval. 2023 LTI Grant Values The 2023 annual LTI grant values for the CEO and other NEOs, as compared to the prior year, are shown in the following table. The number of shares associated with each award is set forth in the Grants of Plan-Based Awards table on page 73. The LTI grant value for Mr. Davis was increased by the Board and the LTI grant values for the other NEOs were increased by the C&MD Committee to strengthen their competitive position versus our primary peer group and reflect their expected future contributions in creating sustained long-term shareholder value.

    The 2021 PSU program concluded at the end of 2023 and the payout is described below. Due to the complexities associated with disentangling our Organon business from a multi-year financial plan, we adjusted the design for the 2021 program as described below. Our Organon business was successfully spun off in June 2021. Following the completion of the spin-off, we reverted to a three-year cumulative EPS and R-TSR design beginning with the 2022 PSU program, with 50% tied to EPS and 50% tied to R-TSR.

    Payouts Under the 2021–2023 PSU Program Performance Period For grants issued in 2021, 70% of each NEO’s annual target LTI was converted to PSUs based on the closing price of Merck stock on the date of grant. The number of PSUs ultimately earned is based on our performance against the pre-established EPS target and R-TSR performance. As a result of the spin-off of Organon, the original number of PSUs granted were adjusted to preserve the same intrinsic value as was in place immediately prior to the adjustments. For the 2021-2023 performance period, as a result of the Organon spin-off, one-year (2021) EPS was weighted at 33%, and three-year R-TSR versus our primary peer group was weighted at 67%. If the Organon spin-off did not occur, three-year cumulative EPS would have been used. The outcome of the combined performance resulted in an actual payout of 161% as illustrated below. The 161% payout was based on our strong EPS and R-TSR performance (both above 150%) during the performance period due to the Emergency Use Authorization of LAGEVRIO in the United States in 2021 and our TSR outperforming the median of our primary peer group by nearly 11%.

    Other Compensation Practices Stock Ownership Requirements The C&MD Committee recognizes the critical role that executive stock ownership has in aligning the interests of management with those of shareholders. As such, we maintain a formal stock ownership policy that requires the CEO and other senior executives to hold a certain amount of Merck common stock for so long as they remain in office. The amount of Merck common stock an executive is required to hold is based on a designated multiple of the executive’s base salary. Until the designated multiple of base salary is reached, executives are required to retain in stock a percentage of the after-tax net proceeds associated with stock option exercises and/or PSU and RSU settlements (100% for the CEO and 75% for the other NEOs). In calculating the attainment of our stock ownership requirements, we exclude (1) unexercised stock options and (2) unvested PSUs and RSUs. All NEOs have met their stock ownership requirements.
