Letter From Our

Chairman and CEO

Dear fellow shareholders,

Thank you for your continued trust and confidence in MSCI. In 2025, we delivered another year of strong performance while making important investments in the future of our business. Our results reflect the durability of our franchise, the mission-critical nature of our solutions and the dedication of our people.

Delivering Results

In 2025, MSCI achieved its 11th consecutive year of double-digit adjusted earnings-per-share growth.¹ Total run rate surpassed $3.3 billion, including fourth-quarter recurring net-new subscription sales of $65 million, our second-best quarter on record. Record annual inflows of $204 billion into ETFs linked to MSCI equity indexes helped drive total ETF and non-ETF assets under management linked to our indexes to approximately $7 trillion. In 2025, we also returned substantial capital to shareholders through $2.4 billion in share repurchases and $557 million in dividends during the year.

Accelerating Innovation

The pace of product innovation across MSCI accelerated meaningfully in 2025, with contribution to recurring sales from recently introduced products increasing approximately 20% year-over-year. A key driver of this momentum has been our deployment of artificial intelligence (“AI”) across the business, an area where MSCI has a natural advantage, given the large volumes of data we collect and transform into unique, proprietary institutional-grade datasets, advanced models and mission-critical solutions.

In 2025, we made meaningful progress deploying AI across our operations, our product development and our client-facing solutions. Our AI Portfolio Insights platform combines generative AI with our datasets and risk models to deliver deeper analysis of client portfolios, and has contributed to sales growth in our Analytics solutions. Our GeoSpatial Asset Intelligence solution helps clients assess physical and nature-based risks across nearly 4 million locations for 700,000 public and private companies. We are also applying AI to accelerate our custom-index capabilities, enabling faster design, testing and deployment of customized index and basket solutions.

Internally, AI is helping us improve operational processes and reallocate resources toward growth investments. We believe these benefits can grow over time and further enhance the value of our solutions.

Building in Private Markets and Wealth

Private markets continued to represent a meaningful growth opportunity, and MSCI has invested in building the transparency tools and standards that this expanding asset class requires. We maintain one of the largest private-asset databases in our industry, covering more than $17 trillion in holdings across private equity, private real estate, private debt, infrastructure and natural resources, plus another $57 trillion in real-estate transactions and portfolio assets. Our Private Capital Solutions business delivered significant sales acceleration in the fourth quarter of 2025, driven by demand for solutions that help investors manage total-portfolio allocations, access private-capital intelligence and gain transparency into private-market holdings.

We also continued to expand our presence in wealth management, one of our fastest-growing client segments, where subscription run rate grew nearly 11% during the year. Our MSCI Wealth Manager platform and direct-indexing solutions are helping wealth managers build portfolios, and we see growing opportunities to deliver content across product lines to support this client segment.

Deepening Client Centricity

We have long believed that our success depends on how well we understand and serve our clients. The investment industry is navigating

a period of significant change — driven by advanced technologies, alternative asset classes and emerging risks and opportunities — and our clients rely on MSCI to help them adapt. In 2025, we took steps to align our organizational structure more closely with client segments — including appointing client segment leaders, establishing client-focused quarterly business reviews and redesigning incentive structures to place greater emphasis on recurring sales and cross-functional collaboration. These changes are intended to help us meet clients where they are, anticipate their evolving needs and deliver integrated solutions that address their most important challenges.

MSCI has long benefited from two reinforcing strengths. First, we connect participants across the global investment community by establishing standards and a common language. Second, our integrated OneMSCI ecosystem generates powerful network effects by enabling our product lines to enhance one another. By organizing more closely around client needs, we aim to further strengthen both of these advantages.

Recognizing Baer Pettit

I want to take a moment to recognize C.D. Baer Pettit, who retired from MSCI and our Board of Directors at the end of February, after more than 25 years of service.

Baer has been my closest business partner and friend throughout MSCI’s growth. When he joined us in January 2000, we were primarily an equity-index company serving active asset managers. At every important juncture since, Baer has helped us anticipate and capture the next phase of our development. His leadership across our Coverage, Marketing, Index and Product functions, and his service as Chief Operating Officer, President and Board member, have left an enduring mark on this company. Baer played a central role in expanding our product lines and deepening our integration across business areas. His focus on data quality, client service and competitive differentiation helped build the franchise we have today.

Baer’s intellect, integrity and sense of humor earned him the deep respect and affection of colleagues and clients around the world. He will remain with us in an advisory capacity for a period to support the transition. On behalf of the MSCI team, I thank him for his contributions and wish him and his family every happiness.

Strengthening Leadership

To support our continued development, we appointed Alvise Munari as Head of Client Segments in addition to his role as Chief Product Officer, and Jorge Mina as Chief Operating Officer with responsibility for chairing our AI Transformation Center of Excellence. These appointments are part of a broader effort to build a more client-focused and integrated organizational structure.

We Ask for Your Support

Your vote is very important to us. We encourage you to read both our Proxy Statement and our 2025 Annual Report on Form 10-K in their entirety, and we ask that you support our recommendations. We remain focused on serving our clients and delivering long-term value for our shareholders.

Sincerely,

Henry A. Fernandez

Letter From Our

Independent Lead Director

Dear fellow shareholders,

The independent directors of MSCI and I join Henry in inviting you to attend our Company’s 2026 Annual Meeting. It is a privilege to continue to serve as your Independent Lead Director, and I appreciate this opportunity to update you on the Board’s priorities and work over the past year.

A Board Built for This Moment

The investment industry is in the midst of a profound transformation. AI is reshaping how data is collected, analyzed and delivered. Private markets continue to grow in scale and complexity. Clients are demanding more personalized, integrated solutions that span asset classes and investment strategies. In this environment, the quality and composition of a company’s board of directors matter more than ever.

I am proud of the Board we have built at MSCI. Our directors bring a distinctive combination of deep investment industry expertise, technology leadership, operational experience and strategic vision that is calibrated to oversee a company operating at the intersection of data, technology and the global capital markets. The composition of the MSCI Board is the product of years of thoughtful refreshment designed to ensure that the skills in the boardroom evolve in step with MSCI’s strategy and the broader industry landscape.

Our Board includes former CEOs and senior leaders of major asset management firms who understand firsthand how investors use MSCI’s tools to build portfolios and manage risk. Alongside this investment expertise, we have technology leaders who have built and scaled enterprise platforms, led AI and cloud computing innovation at some of the world’s most important technology companies, and guided organizations through large-scale transformations. This pairing of investment acumen, technology depth and strategic insight gives our Board a unique perspective as MSCI continues to develop and deliver critical tools, data and solutions for the global investment community.

Governance, Culture and Oversight

The strength of a board is measured not only by the credentials of its members, but by the culture in which they operate. At MSCI, we have cultivated a boardroom culture defined by open dialogue, intellectual rigor, constructive challenge and genuine collegiality. Our directors engage with each other and with management with candor and directness, asking thoughtful questions and examining assumptions. We see ourselves as active, engaged fiduciaries whose fundamental responsibility is to represent the interests of MSCI’s shareholders. We work alongside management, while maintaining our independence, to provide informed perspective on strategic choices and ensure that the decisions being made today support durable, long-term value creation for the people we serve — our shareholders.

We work closely with management to evaluate strategic priorities, assess competitive dynamics and review product development and go-to-market strategies. We dedicate significant Board and Committee time to understanding the opportunities and risks presented by emerging technologies, and to ensuring that MSCI’s adoption of AI and other innovations is guided by high standards of data quality, security and responsible use. Throughout, we maintain a focus on sound risk management and disciplined execution of MSCI’s strategy.

Technology and AI Oversight

AI is not a peripheral topic for our Board. It is a key focus of our oversight agenda. MSCI is embedding AI across its platform, from data acquisition and processing to the delivery of client-facing insights. The Board has devoted significant time at both full Board and Committee

meetings to understanding MSCI’s AI strategy and evaluating the investments being made. Our directors with deep technology and AI backgrounds bring critical perspective to these discussions, while our directors with investment industry experience help ensure that we remain grounded in how these developments can support the investment industry. This combination of viewpoints is essential to overseeing the responsible and effective deployment of AI.

Leadership Transitions

In November 2025, C.D. Baer Pettit, MSCI’s President and Chief Operating Officer and a member of our Board since 2023, announced his retirement after more than 25 years of distinguished service to the Company. Baer helped build MSCI into the global franchise it is today, and his operational expertise, client focus and strategic judgment strengthened the Board’s effectiveness during his tenure as a director. On behalf of the entire Board, I extend our deepest gratitude to Baer for his service.

In connection with Baer’s retirement, Henry has assumed the additional role of President, and the appointment of Jorge Mina as Chief Operating Officer and the expanded responsibilities of Alvise Munari as Head of Client Segments and Chief Product Officer reflect both the depth of MSCI’s leadership bench and the Board’s ongoing focus on succession planning. The Board is confident that this team has the talent, experience and vision to continue driving MSCI forward.

Shareholder Engagement

Meaningful engagement with our shareholders is foundational to how this Board operates. In 2025, members of the Board and management held productive discussions with investors on governance, leadership succession, AI strategy, executive compensation and board composition. We listen carefully to the perspectives of our shareholders, and their feedback directly informs our oversight and priorities. We value these conversations and remain committed to ensuring that our shareholders’ perspectives continue to shape the Board’s work.

Our People

Finally, the Board recognizes that MSCI’s success ultimately depends on the talent, dedication and ingenuity of its people. We engage closely with management on leadership development, talent retention and succession planning, and we are committed to supporting a culture that attracts the best minds in the industry and empowers them to innovate, collaborate and deliver for our clients.

On behalf of my fellow independent directors and the entire Board, thank you for your continued trust and support. We are proud to serve as stewards of this great company, and we are confident that MSCI’s Board is the right team to oversee the next chapter of MSCI’s growth. We look forward to hearing your views at the 2026 Annual Meeting and through our ongoing engagement.

Sincerely,

Robert G. Ashe

Proxy Summary

Strong Financial Performance

In 2025, we continued to execute a focused strategy to accelerate growth, improve efficiency and attract the best talent. MSCI delivered another year of growth across key financial and operating measures, reflecting the strength of our subscription-based business model and demand for our products that bring clarity to investment decisions. Our strong results reflect our commitment to building long-term shareholder value.

Financial highlights for the year ended December 31, 2025 include the following:

2025 Financial Highlights


Operating Revenues (in millions except percentages)									Net Income / Operating Income / Adjusted EBITDA* (in millions except percentages)




Diluted EPS / Adjusted EPS* (unaudited)									Run Rate** (in millions except percentages)

* MSCI has presented supplemental non-GAAP financial measures as part of this Proxy Statement. Definitions of and a reconciliation of each non-GAAP financial measure with the most comparable GAAP measure are set forth in Annex B. These non-GAAP financial measures should not be considered as alternative measures for the most directly comparable GAAP financial measures. The non-GAAP financial measures presented in this Proxy Statement are used by management to monitor the financial performance of the business, inform business decision-making and forecast future results.

** Run Rate is a key operating metric and is important because any increase or decrease ultimately impacts our future operating revenues over time. A substantial portion of MSCI’s operating revenues is derived from recurring subscriptions or licenses for products and services that are ongoing in nature and provided over contractually agreed periods, which are subject to renewal or cancellation upon the expiration of the then current term. We measure the fees related to these agreements and refer to this as “Run Rate.” See page 124 of this Proxy Statement for additional information on Run Rate.

In our fall 2025 Corporate Responsibility off-season engagement, we met with shareholders representing approximately 27.1% of our outstanding shares as of September 30, 2025 to discuss topics including executive compensation, board oversight, succession planning and sustainability strategy. Among the recent changes made to our compensation programs in response to shareholder feedback, in 2026, we added a recurring net new sales (“RNN”) performance modifier to time-based RSU awards to further strengthen pay-for-performance alignment.

PROPOSAL 2

Advisory Vote to Approve Executive Compensation (Say-on-Pay)

Aligning Executive Compensation with Company Strategy, Culture and Performance

We believe our executive compensation program was integral to our successful financial performance in 2025. Our executive compensation program is designed not only to closely align the compensation and interests of our named executive officers (“NEOs”) with the interests of our shareholders, but also to reflect the economic realities of our operating environment by directly linking pay with performance.

MSCI’s executive compensation program emphasizes performance-based compensation in the form of cash incentive awards under our Annual Incentive Plan (“AIP”) and equity incentive awards under our Long-Term Incentive Plan (“LTIP”) that focus respectively on the achievement of short- and long-term goals. The following table sets forth the key components of our executive compensation program in effect in 2025.

Short-Term Annual Incentive Plan

Cash Bonus

Long-Term Equity

Incentive Awards for NEOs

80%

Financial

Performance

20%

•Performance Stock Units (earned based on absolute TSR compound annual growth rate (“CAGR”) over a 3-year performance period) with a 1-year post-vesting mandatory holding period

•Performance Stock Options (earned based on cumulative revenue and cumulative adjusted EPS over a 3-year performance period)

•Restricted Stock Units (3-year cliff-vest)

Further aligns NEOs’ interests with stakeholders’ interests by:

•Linking a substantial portion of long-term compensation to the achievement of operational results (revenue and adjusted EPS) and shareholder value creation (TSR)

•Promoting an “owner-operator” mindset among senior leaders with rigorous share ownership guidelines and additional share retention requirements

Key Performance

Indicators

Aligns NEOs’ interests with stakeholders’ interests by:

•Rewarding performance for achievement of strategic goals, which are designed to position the Company competitively

•Promoting strong financial results and shareholder value

•Incentivizing a corporate culture that promotes leadership effectiveness, talent management, employee engagement and supporting Company growth

See page 80 of this Proxy Statement for additional information on Mr. Fernandez’s special PPO award and page 76 of this Proxy Statement for additional information on Mr. Fernandez’s contributions.

In 2025, our CEO received over 90% of his regular annual compensation in the form of “at-risk” variable compensation under the AIP and LTIP (on average, over 85% in the case of our other NEOs).

Annual Incentive Plan

The AIP for Managing Directors, including our NEOs, closely aligns their interests with those of our shareholders by emphasizing a formulaic, performance-driven approach to determining annual cash incentive awards. In 2025, the Compensation Committee increased the weighting of financial criteria under the AIP from 70% to 80% and consolidated the prior individual KPI (20%) and sustainability goal (10%) components into a single 20% individual performance component. In 2025, the financial criteria component consisted of Total Net Sales (40%), Revenue (20%) and Adjusted EPS (20%). The individual performance component was assessed through our Executive Accountability Framework, focusing on corporate culture and leadership effectiveness.

Building on these changes, for 2026, the Compensation Committee transitioned the Managing Director AIP in which our NEOs participate to a fully formulaic structure, eliminating the prior 20% individual performance component for culture and leadership effectiveness. Beginning in 2026, payouts will be determined entirely by achievement against four financial metrics: Recurring Net New Sales (50% weight), Non-Recurring Sales (10%), Revenue (20%) and Adjusted EPS (20%). The Compensation Committee split the Total Net Sales metric into two distinct components: subscription-based growth (or, Recurring Net New Sales) and non-recurring sales, while emphasizing the Company’s strategic priority of driving recurring revenue.

For additional information about the AIP program, please see the discussion on page 72 of this Proxy Statement.

Long-Term Incentive Plan

The LTIP prioritizes sustained, long-term shareholder value creation and facilitates an “owner-operator” mindset amongst our senior executives. Since 2022, the award mix under our LTIP for our NEOs has been comprised of performance stock units (“PSUs”), performance stock options (“PSOs”) and restricted stock units (“RSUs”), the mix of which varies based on position. Consistent with our past practice, Mr. Fernandez and Mr. Pettit were each granted 100% of their LTIP awards in 2025 in the form of PSUs and PSOs tied to performance metrics and were not granted any time-based RSUs.

In 2026, to reflect continued focus on the Company’s business objectives and strategy, the Compensation Committee added an RNN performance modifier to RSU awards that may adjust the number of shares earned, within a range of 100% to 130% of the number of RSUs granted, based on achievement of a specified RNN performance goal over the FY2026 performance period. The Compensation Committee selected RNN as a key driver of sustainable revenue growth and set performance targets at levels it believes to be challenging yet achievable. The Compensation Committee believes that adding this additional performance element to our time-based RSU awards will further incentivize outperformance on future subscription growth and drive our long-term value creation by our employees.

The LTIP for our NEOs comprises a mix of the following:



			PSUs						•Annual grant of PSUs which cover a cumulative three-year performance period. •The PSUs are eligible to vest between 0% and 200%, based on the achievement of an absolute TSR CAGR performance metric. •The PSUs include a one-year post-vest mandatory holding period.


			PSOs						•Annual grant of PSOs which cover a cumulative three-year performance period. •The PSOs are eligible to vest between 0% and 200% based on the combined level of achievement of (i) a cumulative revenue performance goal and (ii) a cumulative adjusted EPS performance goal (each weighted equally). •Share price of MSCI common stock must exceed exercise price for a participant to realize value.


			RSUs						•Annual grant of RSUs to our NEOs (other than Messrs. Fernandez and Pettit) that cliff-vest at the end of a three-year service period. •Commencing with grants made in 2026, RSUs are subject to an upside-only RNN performance modifier that may adjust the number of shares earned, within a range of 100% to 130% of the target number based on performance.

For additional information about the LTIP, please see the discussion beginning on page 77 of this Proxy Statement.

Proxy Summary

2025 Say-on-Pay Vote Results

In recent years, our shareholders have expressed support for our executive compensation program, including at our 2025 annual meeting at which approximately 94.0% of the votes cast approved our “Say on Pay” advisory proposal. This represents the eighth consecutive year of “Say on Pay” approval of 94% or higher.

PROPOSAL 3

Ratification of the Appointment of MSCI’s Independent Auditor

The Audit and Risk Committee periodically reviews the engagement of the independent auditor to assess, among other things, the skills, experience, service levels and costs associated with conducting the annual audit of the Company’s financial statements. PwC has served as our independent auditor since March 2014. The Audit Committee believes PwC’s tenure since 2014 enhances audit quality, providing deep institutional knowledge, operational expertise and efficiencies that support reliable financial reporting.


			2026 PROXY STATEMENT			17

Our Board recommends that you vote FOR the election of all 11 nominees named below.

PROPOSAL 1

Election of

Directors

Proxies solicited by our Board will be voted FOR these nominees unless otherwise instructed.

Our Board currently has 11 directors. Each director stands for election at each annual meeting of shareholders and holds office until his or her successor has been duly elected and qualified or the director’s earlier retirement, resignation, death or removal. In connection with his planned retirement, C.D. Baer Pettit ceased serving on the Board, effective March 1, 2026. All of the nominees presented beginning on page 21 of this Proxy Statement are directors of MSCI as of March 11, 2026. All directors were elected at the 2025 annual meeting of shareholders. The Board believes that each of the nominees brings strong skills and experience to the Board, giving the Board, as a group, the appropriate skills needed to exercise its oversight responsibilities and advise management with respect to the Company’s strategy, risks and opportunities. Our balanced director tenure distribution shown below is also part of our thoughtful Board succession planning that provides institutional continuity and deep knowledge of the Company, while also representing new perspectives.

Each nominee has indicated that he or she is willing and able to serve if elected. We do not anticipate that any nominee will be unable or unwilling to stand for election, but if that happens, your proxy vote authorizes the people named as proxies to vote for another person nominated by the Board, or the Board may elect to reduce its size.

Vote Required and Recommendation

The affirmative vote of a majority of the votes cast with respect to each director’s election at our 2026 Annual Meeting, at which a quorum is present, is required to approve Proposal No. 1. Abstentions and broker non-votes shall not be treated as votes cast. For additional information on the consequences for directors who do not receive a majority of votes cast, please refer to “What happens if a director does not receive a majority of the votes required for his or her re-election?” in Annex A.

Proposal No. 1: Election of Directors

Director Core Competencies

The following tables provide an overview of the skills, experiences, and attributes of our director nominees that the Board considers most relevant to its oversight of MSCI’s strategy, risks, and opportunities. Effective oversight requires a Board with a broad range of skills, backgrounds and perspectives to ensure robust discussion, independent thinking, strong governance and informed decision-making.

The below list of director competencies focus on those that the Governance Committee believes are most relevant to the current needs of the Board. Additional detail on each director nominee’s experiences and qualifications follows their biographies beginning on page 21 of this Proxy Statement.



			Executive Leadership Directors who have served as CEOs, COOs or other senior executives possess critical experience setting and executing strategic priorities across complex organizations, which are necessary skills to help support our growth and the creation of shareholder value.

			Investment Industry Expertise Directors with expertise in the investment industry have a deep understanding of our key clients (e.g., asset managers, banks and brokerages, asset owners, hedge fund managers, wealth managers, private assets investment professionals, insurance companies and corporates) and the use-cases for our product offerings, which provides us with valuable market and client insights.

			Global Perspective As a company with significant global operations, with businesses tied to the global capital markets and with global client and employee bases, we value directors on the MSCI Board with a global perspective who have worked outside of the United States or who have other substantial management or operational experience with international teams or organizations.

			Regulatory, Government and Public Policy Engagement Directors who have significantly interacted with, or who have served as, government officials, regulators or policymakers, provide important guidance and insight on managing complex regulatory and public policy issues affecting MSCI around the world.

			Corporate Development Directors with relevant experience identifying, assessing and executing corporate development opportunities provide insight to us as we define priorities to expand our business through mergers, partnerships and acquisitions. We believe expertise in these areas allows our Board to oversee our corporate opportunities and our efforts to grow our business and maximize return for our shareholders.

			Financial Reporting and Capital Allocation We utilize a variety of financial targets and metrics, and an understanding of accounting, financial planning, financial reporting and financial controls structures is critical to how we measure our performance and report to our investors. Additionally, we value directors who have significant experience with corporate financing activities and equity and debt markets to support appropriate oversight of our capital structure.

			Corporate/Enterprise Risk Management In light of the Board’s role overseeing corporate/enterprise risk management and understanding the most significant risks facing MSCI, including strategic, market, operational, financial, legal, regulatory and reputational risks, we seek directors with experience in corporate/enterprise risk management and oversight.

			Client Relations, Marketing and Brand Development Client-centricity is essential for us to understand and support our clients’ needs. In addition, marketing and brand development are increasingly important to growing our client relationships and footprint. Experience in these areas contributes to the Board’s understanding of changing market conditions and trends and helps us better deploy our innovative tools and solutions to our clients.

			Technology, Data and Cybersecurity Expertise Directors with expertise in current relevant technology and data issues, including artificial intelligence (AI), machine learning, cybersecurity, digital transformation, data security and privacy, big data and analytics, enterprise software and emerging technologies, provide important insights and oversight with respect to the use of technology to optimize and secure our operations, drive efficiencies and product development, and deliver our solutions more effectively to our clients.

			Sustainability and Climate Practices Experience with sustainability or climate practices, goals, tools and strategies used by investors helps us support the needs of our clients, as we enable their efforts to integrate financially material sustainability and climate considerations into their investment processes. Additionally, experience with corporate sustainability or climate practices, including initiatives such as carbon reduction or social practices, contributes to the Board’s oversight of MSCI’s corporate practices in these areas.

			Human Capital Management MSCI is committed to maintaining a performance culture and a high level of employee engagement. Experience in talent management (attraction, development and retention), executive compensation, succession planning and culture are important areas of Board oversight.

MSCI also has a Code of Ethics and Business Conduct for directors, executive officers and employees, which is reviewed annually by the Board.

Corporate Governance

Composition and Board Refreshment

Director Qualifications

The Governance Committee’s charter requires it to review candidates’ qualifications for membership on the Board or a committee of the Board, including making a specific determination as to the independence of each candidate based on criteria approved by the Board (and taking into account the enhanced independence, financial literacy and financial expertise standards that may be required under applicable law or NYSE rules for audit committee membership, and heightened independence standards that may be required under applicable law or NYSE rules for compensation committee membership). If the Governance Committee determines that adding a new director is advisable, it will recommend such individual to the Board for appointment as a member of the Board and any committees, as applicable.

Consistent with our Corporate Governance Policies, when appointing directors, the Board seeks members who combine sound business judgment, professionalism and a broad spectrum of experience and expertise with a reputation for the highest standards of ethics and integrity. The Board believes its composition should reflect a broad range of skills, backgrounds and perspectives. Directors should have experience in positions with a high degree of responsibility, be leaders or senior managers in the companies or institutions with which they are or were affiliated and be selected based upon contributions they can make to the Board and management and their ability to represent and advance the interests of the Company and its shareholders.

Tenure and Board Refreshment

Our Board has shown an ongoing commitment to Board refreshment and to having highly qualified, independent perspectives in the boardroom. Six of the Company’s director nominees have been added to the Board since the beginning of 2020. The average tenure of the independent director nominees is currently 7.2 years. The average tenure is 8.2 years if Mr. Fernandez is included. Our Corporate Governance Policies provide that directors should not stand for re-election following their 75th birthday.

Corporate Governance

Director Re-Nomination

The Governance Committee also assesses the performance of current directors in its evaluation of current directors for re-nomination to the Board or re-appointment to any Board committees.

New Director Search Process

We are committed to ongoing thoughtful refreshment, with two directors added in 2024, expanding the Board’s expertise in AI, cyber and asset-management depth. Director appointments are the result of the search process outlined below.

Director
Recruitment
Process

The Governance Committee, with the feedback of the full Board, identifies key skills that would best serve the future needs of the Board and the Company, while helping the Board to execute on its current strategic priorities. This includes considering feedback from the Board’s annual self-evaluation process.

The Governance Committee may retain a professional search firm to identify and evaluate director candidates, prioritizing relevant experience. This ensures a comprehensive search and broad pool of potential candidates, with input from the Board.

Identification
and Interview
of Candidates

The Governance Committee identifies a short list of high-potential candidates, and the search firm conducts an initial assessment of these candidates’ skills, experience, background and availability to commit to Board service.

The Chair of the Governance Committee meets with a number of candidates. Certain candidates also meet with members of the Governance Committee, the Chairman and the Lead Director.

Board
Decision and
Nomination

The Governance Committee presents qualified candidates to the Board. In reviewing the potential candidates, the Board takes into account the qualifications discussed in “Director Qualifications” of this Proxy Statement and in MSCI’s Corporate Governance Policies. Upon completion of its assessment, the Governance Committee reports its recommendations for nominations to the full Board. Following discussion of a candidate’s qualifications and consideration of the independence of such candidate, where applicable, the Board formally appoints the candidate to the Board.

Active Board

Our Board blends industry-specific experience in investment management and global markets with expertise in key strategic areas such as technology, marketing and human capital.

Proxy Access

Our Bylaws permit a shareholder, or a group of up to 20 shareholders, owning at least three percent of the Company’s outstanding common stock continuously for at least three years to nominate and include in the Company’s annual meeting proxy materials director nominees constituting the greater of two directors or twenty percent of the total number of directors on the Board, provided that such shareholder(s) and nominee(s) satisfy the requirements specified in the Bylaws.

Shareholder Right to Call a Special Meeting

Our Bylaws permit shareholders of record or beneficial owners holding not less than 15% of our outstanding shares continuously for at least one year the right to call a special meeting of shareholders.

Corporate Governance

Board Culture

The Board has established a boardroom dynamic that supports informed decision-making and oversight. One of the hallmarks of the Board’s culture is meaningful and robust discussion, where views are thoroughly debated and varied perspectives and independent thinking are encouraged and welcomed. Directors consistently ask probing questions of both management and each other so that decisions reflect thorough deliberation. The independent directors meet regularly in executive session without management present, and individual directors have direct access to senior leaders across the organization. Each member of the Board is committed to promoting shareholder interests, and members of our Board regularly engage directly with our shareholders.

The Board conducts an annual self-assessment of Board culture, leadership structure, committee effectiveness, skills and continuing education, which includes individual director feedback and 1:1 meetings with the Lead Director, with findings driving ongoing improvement.

Engagement with Management

Corporate Governance

Structure of Our Board

Substantially Independent Board

Under the MSCI Corporate Governance Policies, the full Board affirmatively determines the independence of directors and reviews the financial and other relationships between the independent directors and MSCI as part of its assessment of director independence. The Governance Committee also makes specific determinations as to the independence of each candidate when reviewing candidates’ qualifications for membership on the Board or a committee of the Board. Director independence is also monitored by the full Board on an ongoing basis.

Our Corporate Governance Policies provide that the Board should have a significant majority of independent directors meeting the independence requirements of the NYSE. Currently, a significant majority of the directors on our Board are independent. As of March 11, 2026, there


All of our non-employee directors are independent

are 11 directors on our Board, comprised of: (i) our Chairman and CEO and (ii) 10 independent directors. Our Board has determined that each of Messrs. Ashe, Perold, Rattray, Smith, and Taneja and Mmes. Matlock, Riefler, Seitz, Volent and Yang is independent in accordance with the requirements of our Corporate Governance Policies, which follow NYSE rules and guidelines. In making such determinations, there were no material transactions, relationships or arrangements not disclosed in this Proxy Statement under “Other Matters—Certain Transactions” to be considered by the Board in determining whether each director was independent. Therefore, 10 of our 11 current directors are independent. Mr. Fernandez is not independent because of his position as CEO of MSCI.

All members of the Audit Committee, Compensation Committee, Governance Committee and Strategy Committee satisfy the independence requirements of the NYSE. In addition, each member of the Audit Committee and Compensation Committee meets the heightened independence standards of the NYSE required for audit committee and compensation committee members, respectively.

Board Leadership

The Board seeks to achieve the best board leadership structure for the effective oversight of MSCI’s affairs. The Board believes that its leadership structure must be considered in the context of the individuals involved and the specific circumstances facing MSCI. The Governance Committee is responsible for the ongoing review of the governance structure of the Board and for recommending to the Board those structures and practices best suited to MSCI and its shareholders.

The Board regularly reviews its leadership structure and believes that it is in the best interests of MSCI and its shareholders to combine the roles of Chairman and CEO at this time, alongside a robust and independent Lead Director. The Board believes that the decision as to whether the positions of Chairman and CEO should be combined or separated, and whether an executive or an independent director should serve as Chairman if the roles are split, should be based upon the particular circumstances facing MSCI. Maintaining a flexible policy allows the Board to choose the leadership structure that best serves the interests of the Company and its shareholders at any particular time.

In determining the Board’s current leadership, among other factors, the Board considered and evaluated the importance of consistent, unified leadership to execute and oversee the Company’s strategy; the strength of Mr. Fernandez’s vision for the Company and the quality of his leadership; the strong and highly independent composition of the Board, including having fully independent committee leadership and membership; the views and feedback heard from our investors through our ongoing engagement programs expressing support for our Board leadership structure; and the meaningful and robust responsibilities of the independent Lead Director. As Chairman, Mr. Fernandez chairs Board meetings and the annual shareholder meeting, works with the Lead Director to set agendas for Board meetings (which the Lead Director approves), collaborates with the Board on the Company’s strategy and leads management in implementing that strategy.


32

Corporate Governance

A strong, independent Lead Director with clearly defined duties and responsibilities further enhances the contributions of MSCI’s independent directors, which have been, and continue to be, substantial. Our Corporate Governance Policies provide for the appointment of a Lead Director from among the Board’s independent directors whenever the Chairman is not independent. The Lead Director role supports the independent directors to provide effective, independent Board leadership and oversight of management.

Robert G. Ashe has been our Lead Director since April 2018. As a former member of other public company boards, the former CEO and CFO of a public company and an audit committee financial expert, Mr. Ashe also has significant experience with respect to the Board’s roles and responsibilities, including those related to risk oversight and the Board’s design and leadership structure. Further, our Chairman and Lead Director work closely to discuss strategic initiatives for the Company and to ensure the Board is effectively exercising its oversight responsibilities and its consideration of the Company’s significant risks and opportunities. The Board, in executive sessions of independent directors (which are presided over by the Lead Director), also considers and discusses risk-related matters. These sessions provide a forum for candid discussion of risk-related matters, without management or the Chairman and CEO present.

The Lead Director’s responsibilities include:

Board

Structure

•Advises and provides feedback to the Governance Committee and the Chairman on the structure of the Board and its leadership, including membership of Board committees and the selection of committee chairs

•Maintains authority to retain independent legal, accounting or other advisors in connection with meetings of independent directors

Shareholder

Engagement

•Consults and directly communicates with shareholders and other key constituents, as appropriate

•Participates in our annual off-season engagement efforts where we meet with many of our top shareholders to discuss our corporate responsibility practices, among other topics


			2026 PROXY STATEMENT			33

Corporate Governance

While we believe that combining the roles of Chairman and CEO is the most effective leadership structure for our Board and the Company at this time, our Bylaws and Corporate Governance Policies also permit a structure where the CEO would not serve contemporaneously as the Chairman of the Board should the separation of such roles be determined appropriate and in the best interests of MSCI and its shareholders in the future.

Committees of the Board of Directors

Our Board has adopted a written charter for each of the Audit Committee, Compensation Committee, Governance Committee and Strategy Committee setting forth the roles and responsibilities of each committee. The Board and each committee may, from time-to-time, form and delegate authority to subcommittees when appropriate. Each committee annually reviews and assesses the adequacy of its charter and recommends any proposed changes to the Board for approval. You may access these charters through the “Corporate Governance” link under the “Investor Resources” tab found on our website’s Investor Relations homepage (https://ir.msci.com).

Engagement and Evaluation of Our Board

Attendance at Board Meetings and Annual Meeting of Shareholders


			Each director attended at least
8	8	4	75	percent

Board meetings	Executive Sessions, which followed the Board meetings	occasions where the Board took action by unanimous written consent	of the total Board meetings and committee meetings on which the director served that were held while the director was a member

Our Board met eight times, held independent director executive sessions following all eight meetings and took action by written consent on four occasions during 2025. Each director attended at least 75% of the total meetings of the Board and committees on which the director served that were held while the director was a member.

Discussions between the Board and management on strategic direction, new business opportunities and the scope and mix of the Company’s products were held at each quarterly Board meeting. In addition to formal meetings, members of our Board informally interact with senior management on a periodic basis and participate in director education sessions.

Our Corporate Governance Policies state that directors are expected to attend the annual meetings of shareholders. In 2025, eleven of our twelve directors who were on the Board at the time attended our annual meeting of shareholders.

Independent Director Meetings

Our Corporate Governance Policies provide that our Lead Director will preside over non-employee director sessions. Mr. Ashe presided over independent director sessions following all Board meetings during 2025. The Board’s standing committees also have a practice of holding executive sessions after their quarterly meetings. Our Corporate Governance Policies further provide that if any non-employee directors are not independent, then the independent directors will meet at least once a year in an independent director session and the Lead Director will preside over each such independent director session. During 2025, all non-employee directors were independent.

Director Education and Orientation Program

Directors are encouraged and provided with opportunities to attend educational sessions on subjects that can assist them in performing their duties. Pursuant to the Director Education Policy, the Company will reimburse directors for reasonable costs incurred from attending these sessions. Directors also participate in an annual review of leading corporate governance practices by corporate governance experts, briefing sessions on topics that present special risks and opportunities and regular updates on accounting topics.

The Company is also part of a peer-engaged program designed to enhance director performance, and we leverage virtual platforms to provide deep-dive sessions on certain aspects of MSCI’s business outside of quarterly meetings including on emerging and strategically important topics. In 2025, we conducted board education sessions to strengthen the Board’s expertise on cybersecurity, strategy process and client coverage. Education topics are identified based on the evolving needs of the business and the Board’s oversight responsibilities.

All new directors participate in a director orientation program that includes briefings by senior management representing the product lines and key functional areas on topics that include the Company’s strategic plans, capital structure, product overviews, historical financial performance and key policies and practices, including compliance and trading policies. We leverage MSCI’s hybrid work environment to hold orientation sessions virtually to provide for participation by senior management around the world. In addition, new directors are encouraged to attend all committee meetings during their first year on the Board.

Corporate Governance

Board Evaluations

The Board conducts a rigorous annual evaluation to support its effectiveness. Directors assess areas such as Board culture, leadership, committee performance, skills and continuing education, either through a self-assessment or by engaging an independent third party. The feedback, along with insights from one-on-one meetings with the Lead Director, is discussed during executive sessions, with follow-up actions taken as needed.

Initiation of Process

Members of the Governance Committee provide thoughts on the factors to be used in evaluating the Board, its committees and individual directors. The Governance Committee also oversees and approves the process and guidelines for the annual evaluation of the performance and effectiveness of the Lead Director.

Evaluation

Each director completes an anonymous self-assessment questionnaire covering a range of topics, including Board structure, Board culture, composition, refreshment priorities, oversight of risk and the roles of the Board and its committees. On an annual basis, the Lead Director also conducts individual director evaluations through interviews with each director.

Discussion

The Corporate Secretary compiles the quantitative and qualitative data from this evaluation and consults with the Lead Director and the Chair of the Governance Committee on the results. The Lead Director and Chair of the Governance Committee review the results with the full Board in executive session.

Follow-up

The Lead Director and Chair of the Governance Committee facilitate discussions during Governance Committee meetings on Board feedback and potential enhancements to governance practices.

Recent Enhancements

Strategic Goals:

•Board and committee agendas increasingly focus on strategic and forward-looking topics

•Increasing use of scorecards to measure progress against strategic objectives

Cybersecurity and Business Resiliency:

•Emphasis on cyber preparedness, operational resiliency and crisis management capabilities

Director Education:

•Virtual deep-dive sessions outside of quarterly meetings

Board Refreshment:

•Commitment to refreshment to ensure proper mix of skill sets for the Board and directors to align with strategic priorities

Succession Planning:

•Increased focus on succession and progression planning for senior management

•Progression candidates invited to speak at Board and Committee meetings for additional exposure

•Succession and progression planning at levels beyond the Management Committee

The Board may periodically engage a third party to provide an external perspective as part of its evaluation process. In 2024, the Board retained a third-party firm to review its practices and effectiveness. The firm conducted interviews with the full Board and collected feedback from select members of senior management, gathering insights on areas such as skills, governance, culture and effectiveness. The feedback was discussed by the Board during executive sessions, and recommendations were identified to enhance the Board’s practices.

Shareholder Engagement

We believe that engaging with our shareholders, prospective shareholders and sell-side analysts is the best way to address the issues that matter most to them. Dialogue with these constituencies helps us understand their perspectives on the Company, and helps us identify issues that might affect our long-term strategy, corporate governance and compensation practices. We offer several opportunities to provide feedback to our Board and senior management, including from time to time inviting certain shareholders to address the Board to present their views on the Company.

Our Investor Relations team leads year-round outreach efforts with our investors and the investment community. During these engagements, we typically discuss topics such as market trends affecting our industry, the competitive environment, our go-to-market strategy, our financial performance and our overall outlook.

Annual Corporate Responsibility Roadshow

We engage with shareholders before, during and after the proxy season, including by hosting an annual off-season Corporate Responsibility Roadshow each fall, to review and receive feedback on our governance practices, sustainability considerations, workforce and talent strategies, and the design of our executive compensation program. The feedback we receive from these discussions is carefully considered by the Board and relevant Board committees.

Our engagement team, which included members of our Corporate Responsibility, Legal, Investor Relations and Executive Compensation teams, met with shareholders representing approximately 27.1% of our outstanding shares in 2025. Our Lead Director and the chairs of the Compensation and Governance Committees participated in the 2025 Corporate Responsibility Roadshow as well, with a director present at each meeting with shareholders.

Oversight by Our Board

Risk Oversight Responsibilities and Processes

Our Board is responsible for, and committed to, the oversight of MSCI’s long-term strategic plan and significant enterprise-wide risks. In carrying out this responsibility, the Board’s role in risk oversight is consistent with the Company’s leadership structure, with management having day-to-day responsibility for identifying, evaluating and managing the Company’s risk exposure and the Board having the ultimate responsibility for overseeing risk management governance, with a focus on the Company’s most significant risks.

The risks include those monitored at a Board or committee level pursuant to committee charters, as well as other risks identified as part of management’s enterprise risk management (“ERM”) program. These risks do not represent a complete list of all risks that are considered and addressed from time to time by the Board, its committees or MSCI management.

Corporate Governance

Cybersecurity and Information Security Awareness

Our Board recognizes that the security of our technology is integral to our products, business processes and infrastructure. We have an enterprise-wide information security program designed to secure our technology assets, and we have implemented several measures to identify, assess and manage related risks. Our CISO manages this program in collaboration with our business and corporate teams. Our cybersecurity policies, standards and procedures align with industry standards, including the U.S. National Institute of Standards and Technology (“NIST”) cybersecurity framework and International Organization for Standardization (“ISO”) information security standards. The MSCI Information Security Management System has also achieved ISO/IEC 27001:2022 certification.

Our management-level Information and Technology Risk Oversight Committee (“ITROC”), which is led by our CISO, and includes senior management leaders, provides oversight of key cybersecurity and technology risks, including those related to AI. Our IT risk program also includes an incident response plan that provides for how we detect, respond to and recover from cybersecurity incidents. The plan includes processes designed to triage, assess severity, investigate and remediate any incident, comply with potentially applicable legal obligations and mitigate damage to our brand and reputation.

Quarterly, our CISO updates the Audit Committee on the Company’s IT security program, including an overview of any significant incidents, risks and trends, results from any third-party assessments, risk-mitigation activities, our incident response plan, and cybersecurity threat developments. This quarterly update is also made available to the full Board, and the Chair of the Audit Committee informs the Board of any key updates during quarterly reports to the Board. The Board periodically conducts education sessions on cybersecurity trends and risks. Additional information regarding our IT risk management is detailed in our 2025 Annual Report on Form 10-K.

Artificial Intelligence (AI) Awareness

MSCI incorporates AI technologies, including generative AI, into its products and operations to drive product innovation, enhance client outcomes and enhance productivity. Given the strategic importance and evolving risk profile of AI, the Board maintains oversight of both the opportunities and risks associated with MSCI’s AI activities.

The Board oversees AI-related risks and opportunities as part of its broader oversight of business strategy and enterprise risk management. The full Board regularly receives briefings from management on the impact of AI on the Company’s business, products and competitive environment and engages with management on the Company’s AI strategy, including product development and investment priorities. The Audit Committee has responsibility for oversight of technology and cybersecurity risks, including risks and opportunities related to AI. Management supports the Board and its committees through MSCI’s enterprise risk management program, including regular reporting and escalation processes, and provides updates regarding the Company’s AI governance framework and significant AI initiatives. Several members of the Board bring relevant experience in technology, data and AI-related fields, as reflected in the Board’s skills matrix on page 19 of this Proxy Statement.

Our management-level AI governance review process is overseen by a cross-functional team that evaluates AI use cases across the organization and reports to senior management. The process is designed to identify and mitigate risks to the Company and our clients, including business, legal, compliance and IT risks, while supporting efficiency and alignment with the Company’s strategy. The framework incorporates privacy, data security, potential bias, regulatory requirements and intellectual property considerations.

Our internal acceptable use policy establishes guidelines for the use of systems and related technology, including requirements regarding approved AI tools, restrictions on the use of public AI tools and governance review of specified AI use cases.

Privacy Awareness

Integrated with our IT security program and our enterprise risk program is our global privacy program. Our privacy program is led by our Chief Privacy Officer and the members of the MSCI Privacy Office, which reports to our CISO, and has been developed based on industry standards, including the NIST Privacy Framework. Our Privacy Steering Committee meets on a quarterly basis to review key risks and trends, progress on key initiatives, focus topics and regulatory developments. We also regularly undertake privacy and data protection training and testing of our employees. Our CISO’s quarterly updates to the Audit Committee include any notable updates relating to our privacy program.

Management Succession Planning

The Compensation Committee oversees talent management matters, including efforts relating to succession/progression planning, career progression and retention strategies, and learning and leadership development. Our CEO meets with our functions to review talent plans with an aim to identify top talent who have the most potential to progress to senior roles at MSCI. The Board views management succession planning as a critical element of its oversight responsibilities and a key driver of long-term value creation.


			2026 PROXY STATEMENT			49

Corporate Governance

To align the management succession and progression process with MSCI’s strategic objectives, the Compensation Committee consults with the CEO to periodically review the Company’s succession plans, including for the CEO and other executives. This process covers selection, succession in the event of incapacity, retirement or removal of an executive, and evaluations of, and development plans for, potential successors to each of the executives. In addition to the Company’s long-term succession plans, the Compensation Committee maintains and reviews an emergency contingency succession plan designed to ensure business and operational continuity in the event the CEO is unexpectedly unable to serve. The contingency plan identifies internal candidates who could assume critical leadership responsibilities on an interim basis.

The Company’s Management Committee, consisting of the Company’s senior-most leaders, engages in discussions focused on succession and progression plans with an emphasis on growth opportunities for potential future senior leaders. High-potential leaders are identified for additional responsibilities to challenge them and develop additional skills. These individuals are often positioned to interact more frequently with the Board, through Board and Committee presentations and discussions, as well as informal events and interactions, throughout the year.

The Board and its committees engage in succession-related activities on a recurring basis throughout the year, including:

Developing Our Next Generation of Leaders

Ongoing Exposure and Review

Formal Succession and Progression Planning

High-potential leaders are given exposure to our directors through formal presentations at Board or committee meetings, informal virtual education sessions, one-on-one meetings with individual directors and participation in other Board activities. The Board also holds ongoing reviews of our leadership bench.

The Compensation Committee holds an annual formal succession and progression planning session led by our CEO, Chief Human Resources Officer and Head of Executive Talent, which all directors are invited to attend. This session includes identifying potential successors, and reviewing succession and progression plans and opportunities to hire from the market, for all senior management positions. This session also may include participation by external talent consultants we have engaged to assist in identifying and evaluating candidates and to ensure that we are considering a large pool of candidates from a wide variety of backgrounds and experiences.

The Compensation Committee reviews succession and contingency planning for our CEO and members of our Management Committee.

Recent Leadership Appointments

The effectiveness of MSCI’s succession and development process is demonstrated by the Company’s ability to draw on its deep leadership bench to execute orderly transitions and drive continued growth. Over the last year, the Company made the following senior appointments from its succession and progression pools:

•In November 2025, the Company announced that C.D. Baer Pettit, President, Chief Operating Officer and member of the Board of Directors, would retire in early 2026 after more than 25 years in senior leadership roles at MSCI. Mr. Pettit’s retirement reflects an orderly transition enabled by the Board’s ongoing succession planning process.

Compensation, Talent and Culture Governance

The Compensation Committee operates under a written charter adopted by the Board and is responsible for reviewing and approving annually all compensation awarded to the Company’s Executives, including the CEO and our other NEOs. The Compensation Committee also regularly engages with our CEO, Chief Human Resources Officer, Head of Executive Talent, Chief Responsibility Officer and other members of senior leadership on a broad range of workforce and talent management topics. The Board regularly receives reports from the Compensation Committee on workforce and talent management topics throughout the year. The Compensation Committee annually reviews the Company’s talent management strategies and programs with respect to senior levels in the organization and key performance metrics, and periodically reviews open senior management roles, future talent needs, the Company’s corporate culture and learning and development programs, as well as the results of the Company’s employee engagement survey. See page 36 of this Proxy Statement for additional information on the Compensation Committee’s responsibilities.

The principal compensation plans and arrangements applicable to our NEOs are described in the “Compensation Matters” section of this Proxy Statement and the executive compensation tables included therein. The Compensation Committee may delegate the administration of these plans and arrangements, as appropriate, including to one or more officers of the Company, subcommittees or to the Chair of the Compensation Committee, in each case, when it deems doing so to be appropriate, in the best interests of the Company and consistent with applicable law and NYSE requirements.

The Compensation Committee has the authority to retain and terminate any compensation consultant assisting the Compensation Committee in the evaluation of CEO or other executive officer compensation. As further described in the “Compensation Discussion and Analysis” section included herein, during 2025, the Compensation Committee continued to retain Semler Brossy Consulting Group, LLC (“Semler Brossy”) as its own independent compensation consultant to review CEO and other executive officer compensation. All of the services provided by Semler Brossy to the Compensation Committee during 2025 were to provide advice or recommendations on the amount or form of executive officer and director compensation, and Semler Brossy did not provide any additional services to the Company during 2025. The Compensation Committee has considered, among other things, the factors delineated in Rule 10C-1 under the Exchange Act (“Rule 10C-1”), including the NYSE listing rules implementing Rule 10C-1 and Semler Brossy’s conflict of interest policies, and determined that the engagement of Semler Brossy does not raise any conflict of interest or other factors that compromise the independence of its relationship with the Compensation Committee. The Compensation Committee annually considers the performance and independence of Semler Brossy. In developing its views on compensation matters and determining the compensation awarded to our CEO and other executive officers, the human resources department provides data and analyses to aid the Compensation Committee in its decisions. The CEO makes recommendations on compensation for executive officers other than himself, and the Compensation Committee takes these recommendations into account in reaching its compensation decisions. The CEO is not present during discussions or decisions regarding the CEO’s compensation. From time to time, the Compensation Committee may obtain input from external legal counsel, including Davis Polk & Wardwell LLP (“Davis Polk”), on compensation award documentation and other compensation-related practices, which in 2025 was communicated to the Compensation Committee via management, the legal department or the human resources department. In light of this relationship, the Compensation Committee has considered, among other things, the factors delineated in Rule 10C-1, including the NYSE listing rules implementing Rule 10C-1 and Davis Polk’s Principles and Guidelines for Advice to Compensation Committees.

Stock Ownership Guidelines

Director Compensation

Director Compensation Best Practices



Robust Director Stock Ownership Guidelines			In January 2026, the Compensation Committee amended the stock ownership guidelines for non-employee directors so that each non-employee director is required to own a target number of shares of stock of the Company having an aggregate value equal to seven times the Company’s annual cash retainer for non-employee directors for service on the Board.


Anti-Hedging and Anti-Pledging Policy			We prohibit all directors and employees, including all NEOs, from hedging or pledging the Company’s common stock or engaging in short sales, purchases or sales of options, puts or calls, as well as derivatives such as swaps, forwards or futures and trading on a short-term basis in the Company’s common stock.


Emphasis on Equity Compensation			The most significant portion of non-employee director compensation is the annual RSU equity award for service on the Board.


Shareholder Approved Limit on Annual Director Compensation			At our 2025 annual meeting of shareholders, our shareholders approved an annual limit on the total annual compensation (cash and equity awards) that our non-employee directors may receive for service on the Board of $1,000,000 in the aggregate per director. This cap cannot be increased without the approval of our shareholders.

Director Compensation Program

The Compensation Committee reviews non-employee director compensation every two years and recommends changes, when appropriate, to the Board. This review includes consideration of MSCI’s non-employee director stock ownership guidelines. The Compensation Committee is aided in its review by its external independent compensation consultant, Semler Brossy. The Compensation Committee takes into account peer benchmarking and broader general industry practices to establish non-employee director compensation.

Committee Membership Fees

Director Compensation and Stock Ownership Guidelines



			Following a review of peer company and market practice, the Compensation Committee approved certain adjustments to our director compensation program for 2026. Effective May 1, 2026, the grant date values of the annual RSU equity awards for each non-employee director will increase by $20,000 to $230,000 and for the Lead Director will increase by $30,000 to $290,000. In addition, the cash retainer for serving as chair of the Audit Committee will increase by $10,000 to $40,000, the cash retainer for serving as chair of our other committees will increase by $5,000 to $30,000 and the cash retainer for serving on each of our committees will increase by $5,000 to $15,000.

Directors may elect under the terms of the MSCI Inc. 2025 Omnibus Incentive Plan (the “2025 Omnibus Plan”) to receive their cash retainer in the form of shares of our common stock. Under the 2025 Omnibus Plan, non-employee directors are subject to annual limits on their cash and equity compensation, which were approved by our shareholders at our 2025 annual meeting of shareholders, as follows: non-employee directors may not receive in any calendar year compensation, including equity awards and cash compensation, in excess of $1,000,000 in the aggregate per director. These caps cannot be increased without the approval of our shareholders.

RSUs granted to non-employee directors are granted on May 1 of each year and vest on the first anniversary of the grant date. Cash retainers and RSU awards are prorated when a director joins the Board and/or a committee at any time other than May 1. RSUs granted on or after May 1 vest on the next May 1 to occur following the grant date. For example, if a director joins the Board on February 1, 2026, his or her prorated RSUs will vest on May 1, 2026. If a director joins the Board on May 31, 2026, his or her prorated RSUs will vest on May 1, 2027.

RSUs are recognized as an expense in the Company’s financial statements for financial reporting purposes with respect to 2025 in accordance with FASB ASC Subtopic 718-10.

Holders of these RSUs are entitled to participate in dividend equivalent payments, and such payments may be settled in cash, shares of our common stock, or a combination thereof, to be decided by the Company in its sole discretion. Prior to the conversion to shares, RSU holders do not have any rights as an MSCI shareholder with respect to such RSUs, including the right to vote the underlying shares. The RSUs are generally non-transferable; however, our Board may, in its discretion, specify circumstances under which an award may become immediately transferable and non-forfeitable or under which the award will be forfeited. The RSUs vest and convert to shares immediately upon termination of service for reasons of death, disability or a change in control. If service as a director terminates for any other reason, all unvested RSUs will be cancelled and forfeited unless determined otherwise by the Board or the Compensation Committee.

Non-employee directors are reimbursed for expenses incurred in connection with attending Board meetings and educational sessions.

Director Deferral Plan

Under the MSCI Inc. Non-Employee Directors Deferral Plan (the “Deferral Plan”), our directors are permitted to defer receipt of shares of our common stock payable in lieu of cash retainers and/or upon conversion of RSUs granted to the director following the year for which an election has been submitted; provided that an election made by a director within 30 days after the director becomes eligible to receive a cash retainer or RSUs shall apply to any common stock payable in lieu of such a cash retainer and/or upon conversion of such RSUs granted to the director following the date on which the director makes the election. Receipt of shares of our common stock may be deferred until a future date specified by the director, a termination of service from the Board, or the earlier of the two. While the Deferral Plan allows for it, the Board has not yet implemented a process for the deferral of cash payments.

(1)Pursuant to MSCI’s Third Amended and Restated Articles of Incorporation, directors hold office for a term expiring at the next annual meeting of shareholders. The Board term beginning in April 2025 and ending in April 2026 (the “2025 Board Term”) and the Board term beginning in April 2024 and ending in April 2025 do not coincide with MSCI’s calendar-year fiscal year. Amounts included in the table above represent cash earned or paid, or stock awards granted, as applicable, during the year ended December 31, 2025. Because directors are paid for service from May 1 to April 30, any prorated amounts are calculated from the applicable date to May 1 of the relevant Board term.

(2)Cash amounts in this column include the annual retainers and committee fees paid during the year ended December 31, 2025. Three of our directors elected to receive all or a portion of their annual cash retainers in stock as set forth below. The number of shares issued was determined by dividing the aggregate value of the elected portion of the cash retainer by the closing share price of MSCI common stock on the trading day prior to the grant date ($545.11 for Messrs. Ashe and Taneja and Ms. Volent) and rounding down to the next whole number. Mr. Taneja elected to defer receipt of such shares until the earlier of (i) June 1, 2025 and (ii) the 60th day after his “separation from service” as a director under the Deferral Plan. Mr. Taneja’s deferral period lapsed on June 1, 2025, and the deferred shares were delivered to him on such date.


Name	Cash	Stock
Mr. Ashe	—	$109,567.11 (201 shares)
Mr. Taneja	—	$99,755.13 (183 shares)
Ms. Volent	—	$109,567.11 (201 shares)

(3)Represents the aggregate grant date fair value of RSUs granted in 2025 in accordance with FASB ASC Subtopic 718-10. The fair value is calculated by multiplying the closing share price of MSCI common stock on the date prior to the grant date by the number of units awarded. For assumptions regarding these calculations, please see notes 1 and 11 to the consolidated financial statements included in our 2025 Annual Report on Form 10-K filed with the SEC on February 6, 2026. The values in this column may not correspond to the actual value that will be realized by the non-employee directors at the time the RSUs vest. The number of RSUs awarded is determined by dividing the aggregate value of the RSU award by the closing share price of MSCI common stock on the trading day prior to the grant date ($545.11 for Messrs. Ashe, Perold, Rattray, Taneja and Smith and Mmes. Matlock, Riefler, Seitz, Volent and Yang) and rounding down to the next whole number. For the 2025 Board term, each of Messrs. Perold, Rattray, Taneja and Smith and Mmes. Matlock, Riefler, Seitz, Volent and Yang received 385 RSUs and Mr. Ashe received 476 RSUs. These RSUs will vest on May 1, 2026. Ms. Matlock elected to defer receipt of such shares issuable upon vesting until the earlier of (i) June 1, 2033 and (ii) the 60th day after her “separation from service” as a director under the Deferral Plan. Mmes. Riefler and Yang elected to defer receipt of such shares issuable upon vesting until the 60th day after their “separation from service” as a director under the Deferral Plan. Mr. Taneja elected to defer receipt of such shares issuable upon vesting until the earlier of (i) June 1, 2025 and (ii) the 60th day after his “separation from service” as a director under the Deferral Plan. Mr. Taneja’s deferral period lapsed on June 1, 2025, and the deferred shares were delivered to him on such date.

(4)As of December 31, 2025, each of our non-employee directors had the following outstanding stock awards in the form of RSUs: Messrs. Perold, Rattray, Taneja and Smith and Mmes. Matlock, Riefler, Seitz, Volent and Yang each had 385 RSUs outstanding and Mr. Ashe had 476 RSUs outstanding.

(5)Cash amounts in this column include dividend equivalents paid during the year ended December 31, 2025 in connection with the Company’s payment of its quarterly cash dividend. Each of Mmes. Matlock, Riefler and Yang received shares of our common stock and a cash payment for fractional shares received as a dividend equivalent payment for RSUs and in lieu of receiving a cash dividend payment for shares, in each case subject to her deferral election. Mr. Taneja received shares of our common stock and a cash payment for fractional shares received as a dividend equivalent payment for RSUs and shares elected in lieu of annual cash retainer and in lieu of receiving a cash dividend payment for shares subject to his deferral election. The table below sets forth the amounts received by each.

(6)Mr. Edmunds did not stand for re-election at the 2025 annual meeting of shareholders and served on the Board through April 22, 2025, and thus did not receive compensation for the 2025 Board Term.

Non-Employee Director Stock Ownership Guidelines

Our Board believes that our directors should hold a meaningful financial stake in our Company in order to further align their interests with those of our shareholders. On January 27, 2026, the Compensation Committee amended the stock ownership guidelines for non-employee directors to adopt a value-based ownership framework that further strengthens alignment with shareholders. The amended guidelines replace the prior ownership framework that was based on owning a net number of shares resulting from the vesting of RSUs, transitioning to a market-standard dollar-value approach that provides a clear and transparent ownership target.

Under the amended guidelines for non-employee directors, commencing on January 27, 2026, each non-employee director is required, within five years of January 27, 2026 (or, if later, his or her first election or appointment to the Board) to own a target number of shares of our common stock having an aggregate value equal to seven times the Company’s annual cash retainer for non-employee directors for service on the Board. The seven-times multiple reflects the Board’s strong commitment to meaningful, long-term alignment with shareholders. “Annual cash retainer” excludes any committee chair or member fees, lead independent director fees, meeting fees or other additional cash compensation.

Shares that count towards satisfaction of the target level of stock ownership under the stock ownership guidelines for non-employee directors consist of the following:

1.Shares beneficially owned individually, either directly or indirectly (including any shares beneficially owned as a result of an election to receive a retainer (or any portion thereof) in shares);

2.Shares beneficially owned jointly with, or separately by, immediate family members residing in the same household, either directly or indirectly;

3.Shares underlying vested and unvested RSUs granted under the 2025 Omnibus Plan; and

4.Shares for which receipt has been deferred (including any shares held through the Deferral Plan or any other deferred compensation plan maintained by the Company).

As described above, under these guidelines, non-employee directors are required to hold all shares received on the vesting of annual awards until the above requirement is met and maintained. As of the date of this Proxy Statement, all of our non-employee directors are in compliance with the Company’s stock ownership guidelines.


			2026 PROXY STATEMENT			55

Our Board of Directors recommends a vote FOR the approval of the compensation of MSCI’s Named Executive Officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

PROPOSAL 2

Advisory Vote to Approve Executive Compensation (Say-on-Pay)

Proxies solicited by the Board will be voted FOR this approval unless otherwise instructed.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) enables MSCI’s shareholders to vote to approve, on an advisory or non-binding basis, the compensation of our NEOs as disclosed in this Proxy Statement in accordance with SEC rules.

For an overview of the compensation of our NEOs and our compensation strategy, see “Compensation Matters—Compensation Discussion and Analysis—Executive Summary” below.

We are asking for shareholder approval of the compensation of our NEOs as disclosed in this Proxy Statement in accordance with SEC rules, which include the disclosures under “Compensation Matters—Compensation Discussion and Analysis,” the compensation tables included herein and the narrative following the compensation tables. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the policies and practices described in this Proxy Statement.

This vote is advisory and therefore not binding on MSCI, the Compensation Committee or the Board. The Board and the Compensation Committee value the opinions of MSCI’s shareholders. To the extent there is any significant vote against NEO compensation as disclosed in this Proxy Statement, we will consider those shareholders’ concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns. MSCI currently conducts annual advisory votes on executive compensation.

Vote Required and Recommendation

The affirmative vote of a majority of the votes cast at our 2026 Annual Meeting, at which a quorum is present, is required to approve Proposal No. 2. Abstentions and broker non-votes shall not be treated as votes cast.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis (referred to as the “CD&A”) section summarizes our general philosophy with regard to the compensation of our Chief Executive Officer (“CEO”), our Chief Financial Officer (“CFO”), and our three next most highly paid executive officers for 2025 (collectively referred to as “named executive officers” or “NEOs”). The CD&A provides context for the executive compensation disclosures presented below in both tabular and narrative form. Under its charter, the Compensation Committee reviews the Company’s compensation strategy and reviews and approves executive officer compensation as well as the Company’s compensation and benefits program generally. The Compensation Committee approved the compensation structure and amounts for each of our NEOs for 2025, which were materially consistent with those approved in 2024 and which were designed to further the Company’s strategic objectives.

Our Named Executive Officers for 2025 are:

Henry A. Fernandez

Chairman, Chief Executive Officer and President

Andrew C. Wiechmann

Chief Financial Officer

C.D. Baer Pettit

Former President and Chief Operating Officer(1)

Alvise J. Munari

Chief Product Officer and Head of Client Segments

Scott A. Crum

Chief Human Resources Officer

(1)Mr. Pettit ceased serving in his position as Chief Operating Officer effective November 12, 2025 and continued to serve in his role as President until March 1, 2026. The Board appointed Mr. Fernandez to assume the role of the Company’s President, effective March 1, 2026.

Highlights

Executive Summary

Our executive compensation program is designed to link pay to performance, encourage prudent decision-making and risk management, and create a balanced focus on short-term and long-term performance that supports sustained, long-term shareholder value creation. In the dynamic and competitive environment in which we operate, it is imperative that we maintain a responsible executive compensation program that encourages and rewards our leaders for achieving short-term and long-term results.

The following table sets forth the key components of our target-based compensation program in effect in 2025.

Elements

Fixed

Component

Variable

Components

Base Salary

Annual Incentive Plan

Long-Term Incentive Program

Philosophy

Each of the three components has a different purpose. The sum of the base salary, target annual cash incentive and target equity incentive creates a target total compensation. Actual cash incentive and equity incentive payouts are dependent upon the achievement of the relevant AIP and LTIP goals tied directly to the performance of the Company and its share price, the product/functional unit and the individual.

We believe that this target-based incentive structure fosters a culture of high performance and accountability and promotes shareholder interests by closely aligning executive compensation with objectively measured Company performance and strategic goal attainment as further described below. The following table sets forth the key components of our executive compensation program in effect in 2025.

•Restricted Stock Units (3-year cliff-vest)

Further aligns NEOs’ interests with stakeholders’ interests by:

•Linking a substantial portion of long-term compensation to the achievement of operational results (revenue and adjusted EPS) and shareholder value creation (TSR)

•Promoting an “owner-operator” mindset among senior leaders with rigorous share ownership guidelines and additional share retention requirements

Strong Financial Performance

In 2025, we delivered strong results, underscoring the strength of our execution and the impact of our long-term investments. Our unwavering client focus has reinforced our position as a trusted partner to the investment community, and our employees’ exceptional performance has been instrumental in achieving these outcomes.

Diluted EPS / Adjusted EPS(1) (Unaudited)


l			Diluted EPS			l			Adjusted EPS


Recurring Net New Sales(2) (Unaudited) (in millions)


Non-Recurring Sales(2) (Unaudited) (in millions)

(1)“Adjusted EPS” is a non-GAAP financial measure and “Diluted EPS” is the corresponding GAAP measure. See Annex B for definitions and reconciliations of all non-GAAP financial measures referenced herein.

(2)Recurring Net New Sales and Non-Recurring Sales are key operating metrics and are important because any increase or decrease in each ultimately impacts our future operating revenues over time. Recurring Net New Sales represent new recurring subscription sales minus the impact of subscription cancellations, capturing the net impact to Run Rate (as defined elsewhere herein) for the period. Non-recurring sales represent the aggregate value of client agreements entered into during the period that generate non-recurring fees and are not included in Run Rate, even if such agreements span multiple periods or years. See page 124 of this Proxy Statement for additional information on Run Rate.

Key 2025 Compensation Decisions

The Compensation Committee, with advice from its independent compensation consultant Semler Brossy, reviewed and approved the Company’s executive compensation program for 2025. In reaching its determinations, the Compensation Committee considered the Company’s strategic objectives and performance, shareholder feedback, peer practice, and relevant legal and regulatory developments.

2025 Annual Incentive Plan - Metric Weightings and KPI Refinement

For 2025, the Compensation Committee refined the AIP for Managing Directors, including the NEOs, with the purpose of strengthening accountability, further aligning incentives with MSCI’s long-term business objectives and ensuring a more structured, measurable approach to individual goal assessment. Under the revised structure for 2025, achievement of financial criteria accounted for 80% of the target annual cash bonus, up from 70%, while the individual performance component accounted for the remaining 20%, down from 30% (which had been split between individual KPIs (20%) and sustainability goals (10%)). The Compensation Committee also refocused the individual performance component on culture and leadership effectiveness.

Key changes to the financial metrics included increasing the weightings of Total Net Sales and Revenue to reinforce the Company’s focus on driving sustainable revenue growth; modestly reducing the Adjusted EPS weighting while maintaining it as a significant component; and eliminating Free Cash Flow as a standalone metric to enhance simplicity and focus participants on the measures most closely tied to financial performance and strategic goals. The Compensation Committee also approved measuring Total Net Sales achievement on a quarterly basis to reinforce year-round focus on sales performance.

2025 CEO Special Incentive Award

The Compensation Committee and the independent members of our Board evaluated the strategic importance of retaining and further incentivizing our Chairman and CEO, Henry A. Fernandez, to drive transformative shareholder value creation. With that goal in mind, on January 31, 2025, the Compensation Committee, with input from the other independent directors of the Board, granted a special grant of premium-priced stock options (the “PPOs”) to Mr. Fernandez, having a total grant date value of $15.0 million.

The PPOs are allocated across three equal tranches of $5.0 million each, with rigorous exercise prices of $1,000, $1,100 and $1,200 (representing premiums of approximately 69.3%, 86.2% and 103.1%, respectively, over the Company’s $590.73 closing share price on January 30, 2025, the trading day prior to the grant date).

Exercise Price vs. Closing Share Price on Trading Day Prior to Special Award Grant Date


			2026 PROXY STATEMENT			61

Compensation Matters

The options cliff-vest on the fifth anniversary of the grant date, subject generally to continued service, and have a ten-year term. The award is designed to reinforce long-term alignment with shareholders because it delivers value only if our share price appreciates meaningfully above the exercise-price hurdles (the award will have a $0 in-the-money value (or spread value) at a $1,000 share price). For the award to deliver any value on the vesting date, the Company’s share price would need to appreciate at a compound annual rate of at least 11% per year over the five-year vesting period. The award is also subject to the Company’s existing stock retention requirements, under which Mr. Fernandez must hold 25% of net shares realized following any stock option exercise through the end of his service on the Management Committee.

See page 80 of this Proxy Statement for additional information on Mr. Fernandez’s special PPO award, page 82 for factors considered by the Board when approving the special PPO award and page 76 for additional information on Mr. Fernandez’s contributions.

2025 LTIP Equity Awards

The structure and terms of our 2025 annual LTIP equity awards (PSUs, PSOs, and RSUs) were unchanged from 2024:



			PSUs						•Granted to all NEOs •Cliff-vest at the end of a cumulative three-year performance period •May earn between 0% and 200% of the target number of shares based on achievement of absolute TSR CAGR performance metric; no payout if achievement is below threshold performance level •Realize meaningful value only to the extent that shareholders also realize value •Include one-year post-vest mandatory holding period, where such shares, or rights with respect to such shares, may not be transferred until the expiration of such holding period •Dividend equivalents only paid if and to the extent the underlying award is earned and vests


			PSOs						•Granted to all NEOs to further facilitate an “owner-operator” mindset and focus on strategic goals •Vest upon satisfaction of both a service condition and a performance condition over a cumulative three-year performance period, with the service condition satisfied on the third anniversary of the grant date •May earn between 0% and 200% of the target number of shares based on the combined level of achievement of a cumulative revenue performance goal and a cumulative adjusted EPS performance goal, each weighted equally, and measured over a three-year performance period •Share price of MSCI common stock must exceed exercise price for a participant to realize value


			RSUs						•Granted to NEOs other than the CEO and President •Cliff-vest at the end of a three-year vesting period •Long-term value of underlying stock tied to share price

Compensation Matters

Key 2026 Compensation Decisions

The Compensation Committee approved targeted changes to the 2026 executive compensation program to strengthen pay-for-performance alignment and focus executives on driving sustainable growth. The principal program changes were:

Annual Incentive Plan - 100% Formulaic Design

The Compensation Committee transitioned the Managing Director AIP in which our NEOs participate to a fully formulaic structure, eliminating the prior 20% individual performance component for culture and leadership effectiveness. Beginning in 2026, payouts will be determined entirely by achievement against four financial metrics: Recurring Net New Sales (50% weight), Non-Recurring Sales (10%), Revenue (20%) and Adjusted EPS (20%). The Compensation Committee split the Total Net Sales metric into two distinct components: subscription-based growth (or, Recurring Net New Sales) and non-recurring sales, while emphasizing the Company’s strategic priority of driving recurring revenue. The 50% weighting on Recurring Net New Sales, the highest-weighted metric in the program, reflects its critical role in building long-term revenue streams that support sustainable shareholder value creation. This change reinforces focus on and accountability for top-line growth and aligns incentive outcomes with business results.

For 2026, Recurring Net New Sales and Non-Recurring Sales will be measured on a quarterly basis, consistent with the quarterly measurement approach applied to Total Net Sales in 2025. Quarterly measurement reinforces consistent sales execution throughout the year, incentivizes strong performance from the start of the year, driving pipeline development and sales momentum, and aligns incentive outcomes with the Company’s operating cadence.

Beginning in 2026, the Compensation Committee added a Recurring Net New Sales (“RNN”) performance modifier to annual time-based RSU grants to directly link equity outcomes to the Company’s subscription revenue growth. The modifier is measured over the FY2026 performance period and is based on achievement of an RNN performance goal. RNN is defined as net new recurring subscription sales (new recurring subscription sales minus subscription cancellations), capturing the net impact to Run Rate for the period. The Compensation Committee selected RNN as a key driver of sustainable revenue growth and set performance targets at levels it believes to be challenging yet achievable. The Compensation Committee believes that adding this additional performance element to our time-based RSU awards will further incentivize outperformance on future subscription growth and drive our long-term value creation by our employees.

The modifier is upside-only: if RNN growth meets or exceeds the performance threshold, the number of RSUs subject to the award may increase up to 130% of the original grant, with results between threshold and maximum determined by linear interpolation. Performance below threshold results in no adjustment to the original grant. This design adds a performance dimension to RSUs while preserving their core retention value.

Executive Compensation Philosophy and Goals

We evaluate our executive compensation structure on an annual basis to ensure alignment with our compensation philosophy, business strategy and shareholder priorities. Our compensation program for our NEOs is designed to promote the achievement of our short-term and long-term financial and strategic goals. For additional information on our financial performance, see page 60 of this Proxy Statement.

In addition to the principles described in the “Executive Summary” on page 58 of this Proxy Statement, our executive compensation program is designed to:

•promote achievement of financial and strategic goals and provide alignment with our multi-year strategic-planning;

•provide a framework to encourage our NEOs to make a long-term commitment to the Company;

•ground compensation determinations on the performance of the Company;

•attract, retain and engage top-level talent and provide each NEO with compensation opportunities that are competitive with market practices and within our cost structure;

•appropriately manage compensation risk in light of our business strategy;

•align the long-term interests of our senior executives with those of our shareholders by promoting actions that will allow for sustainable top- and bottom-line growth opportunities and capital returns to shareholders; and

•maintain an “owner-operator” culture and strong corporate governance practices.

In furtherance of our pay-for-performance philosophy, the primary financial metrics used in our incentive compensation programs generally reflect those used internally to measure our performance and externally to report to investors, in particular, revenue and adjusted EPS, which are utilized under both our AIP and LTIP. Many of these measures are tied to cash generation, capital efficiency, sustained profitable growth over time, and shareholder value.

Our CEO, Chief Human Resources Officer and CFO annually review the incentive metrics in our executive compensation program with the Compensation Committee to ensure that the program remains balanced and motivates the achievement of the go-forward drivers of our business. The financial metrics used in our 2025 executive compensation program were:


	Metric	Alignment to Broader Strategy
Annual Incentive Plan and Long-Term Incentive Program	Revenue	Represents the top-line measure of our business performance; for the LTIP, measured over a cumulative, three-year basis to align with our strategic planning
	Adjusted EPS(1)	Measures profitability on a per-share basis, including by adjusting for the after-tax impact of significant one-time, unusual or non-recurring items; for the LTIP, measured over a cumulative, three-year basis to align with our strategic planning; encourages a focus on profitability and expense management
Annual Incentive Plan Only	Total Net Sales	Represents net new recurring subscription sales plus non-recurring sales weighted at 75%, which reinforces the Company’s focus on driving sustainable revenue growth
Long-Term Incentive Program Only	TSR CAGR	Measures total company achievement of shareholder returns and encourages sustained value creation

2025 Target Pay Mix

Our executive compensation philosophy provides our NEOs with the opportunity to earn a significant portion of their compensation in the form of variable incentive compensation (i.e., annual cash incentive awards under our AIP and long-term equity incentive awards under our LTIP), with the remaining portion of their total compensation as their base salary. This emphasis on variable incentive compensation is illustrated in the following pay mix charts:

When making compensation decisions for our CEO and other NEOs, the Compensation Committee also considers the views of the other independent directors.

•Certify achievement of performance metrics applicable to any equity awards granted in prior years.

•In most years, establish the AIP structure for the current year, including the applicable AIP financial metrics and target AIP awards for each NEO.

•Establish the structure and performance metrics applicable to equity awards to be granted under the LTIP for the current year, and grant equity awards based on a number of factors, including the Company’s recent performance, peer analysis and the executive’s individual performance and potential future contributions.

March

•Consider risks arising from the Company’s incentive compensation plans.

•Review investor areas of focus.

Independent Compensation Consultant

The Compensation Committee selected and engaged Semler Brossy as its independent compensation consultant to assist with a range of executive compensation matters, including the overall design of our executive compensation program, evaluation and selection of peer group companies, provision of competitive market data, and other matters related to our NEO compensation program. During 2025, Semler Brossy was present at all Compensation Committee meetings, other than the Compensation Committee’s annual in-depth review of senior leader progression planning, and consulted on executive compensation matters, including by reviewing agendas and preparing materials in advance of each meeting and sharing peer and best practices. The Compensation Committee regularly meets with Semler Brossy in Executive Sessions without management’s attendance. Semler Brossy reports directly to the Compensation Committee, which, pursuant to its charter, maintains sole responsibility for retaining or terminating this relationship. Semler Brossy did not provide any other services to MSCI during 2025.

Executive Compensation Considerations

The Compensation Committee considers a range of factors in determining compensation components and setting compensation amounts. In addition to reviewing NEO performance against annual goals, various financial and operational metrics and individual goals, the Compensation Committee reviews peer group analyses (used as a reference without benchmarking to a specified target) and shareholder feedback. The weight attributed to each individual factor may change from time to time, depending on the circumstances of such decisions. We believe this continues to be the best approach for the Company, as it enables the Compensation Committee to balance competing interests, address evolving priorities and meet Company objectives.

2025 Say-on-Pay Vote Results

In 2025, 94.0% of the votes cast on the Say-on-Pay Advisory Vote were voted in support of the compensation of our NEOs.

Shareholder Engagement

MSCI has established a robust process for engaging shareholders on executive compensation. On at least an annual basis, we meet with shareholders to provide an overview of our executive compensation program and highlight recent changes, if any. In our 2025 Corporate Responsibility off-season engagement, the Company contacted our top 18 shareholders, representing approximately 50.6% of our outstanding shares, and met with shareholders representing approximately 27.1% of our outstanding shares as of September 30, 2025 in individual meetings to discuss our executive compensation program. Shareholders generally reacted positively to the Company’s current compensation program and none of the shareholders expressed significant concerns.

As part of our 2025 Corporate Responsibility off-season engagement, we engaged with shareholders on the design and rationale of the CEO special incentive award. Investors who met with us broadly acknowledged the importance of incentivizing continued contributions of Mr. Fernandez during this critical period of industry transformation and viewed positively the structure of the award. Investors specifically cited the rigor of the premium exercise price hurdles and expressed comfort with the award’s structure, noting that the significant premiums to the closing share price on the trading day prior to grant date ensure that Mr. Fernandez participates in value creation only after shareholders have realized substantial appreciation. Several investors highlighted that they view premium-priced options as carrying meaningful additional risk compared to at-the-money awards and that the performance thresholds embedded in the exercise prices are robust.

Better aligns with market practice and is responsive to shareholder feedback

Focus on financial metrics

Increased financial criteria weighting under the AIP from 70% to 80% in 2025 (further expanded to represent 100% of the target annual cash bonus under the 2026 AIP)

Further strengthens alignment between executive compensation and Company financial performance

Focus on operational performance and executive retention

In 2026, added an RNN performance modifier to 2026 RSUs (100%–130% payout based on recurring net new sales performance over the first year of the three-year vesting period)

Reinforces the link between LTIP awards and operational performance

The Company will continue to maintain an active dialogue with shareholders and evaluate feedback on issues of importance to them, including the metrics that drive each of our NEO’s compensation. For additional information about our shareholder engagement efforts, please see page 41 of this Proxy Statement.

Peer Groups

To ensure competitiveness of compensation structures and pay levels for our NEOs, the Compensation Committee conducts an annual review of peer company compensation data. Each year, prior to beginning this review, the Compensation Committee examines the composition of companies previously considered our peer companies to make certain that the selected companies continue to be relevant as evaluated according to the following screening criteria:

•Scale, to reflect similar size and complexity;

•Geographic footprint, to reflect business structure and international complexity;

•Public ownership structure, to ensure availability of data;

•Competitors for talent; and

•Similar business model.

The peer group used to inform fiscal 2025 pay decisions for our NEOs was comprised of 18 companies that, in aggregate, approximated MSCI’s size, scope of operations and operating metrics. In particular, the group was selected such that it, in aggregate:

•Approximated MSCI’s size on a revenue basis for fiscal 2025;

•Reflected MSCI’s high-margin, high-valuation operating metrics and international reach; and/or

•Represented the competitive talent market for financial technology, research and consulting, and data systems/information technology companies.

Review for 2026

In its annual review of the executive compensation peer group for 2026, the Compensation Committee undertook a comprehensive review of the executive compensation peer group following considerable evolution of the industries in which the Company operates over the last few years and the evolution and expansion of the Company’s product lines. As a result, the Compensation Committee removed Dun & Bradstreet Holdings, Inc. (due to its recent acquisition by Clearlake Capital Group, L.P.) and added Tradeweb Markets Inc. (due to its business alignment to the Company in data and analytics offerings) to the peer group that was used as a reference when setting fiscal 2026 pay for our NEOs:

Fixed Compensation

Annual Base Salary

Base salary is the only fixed component of our executive compensation program. The annual base salary element offers our NEOs a measure of certainty and predictability to meet ongoing living and other financial commitments. In setting base salaries for our NEOs, the Compensation Committee has sought to establish base salary rates that (i) are competitive with those provided for similar positions at companies in our peer group and (ii) recognize the experience and performance of the NEO. The Compensation Committee reviews the base salaries of our NEOs on an annual basis. None of our NEOs received an increase in their base salary for 2025, except for Mr. Wiechmann, whose base salary was increased to $600,000 (9.1%), which was intended to align his base salary with competitive market practice.


Name			2025 Base Salary Rate ($)
Henry A. Fernandez			1,000,000
Andrew C. Wiechmann			600,000
C.D. Baer Pettit(1)			823,996
Alvise J. Munari(2)			663,568
Scott A. Crum			550,000

(1)Base salary for Mr. Pettit was paid in British pounds sterling and converted to U.S. dollars using the fiscal year average of daily spot rates of £1 to $1.3184. Mr. Pettit’s 2025 base salary rate was £625,000.

(2)Base salary for Mr. Munari was paid in Swiss francs and converted to U.S. dollars using the fiscal year average of daily spot rates of CHF1 to $1.2065. Mr. Munari’s 2025 base salary rate was CHF 550,000.

Variable Compensation

The variable compensation actually paid to our NEOs is subject to performance metrics that are designed to (i) emphasize pay-for-performance, (ii) balance short-term and long-term incentives, and (iii) take into account input from our shareholders. The variable elements of our target-based incentive compensation program include:

1.an annual cash incentive component; and

2.a long-term equity incentive component.

In determining target cash and equity incentive compensation amounts for each NEO, the Compensation Committee takes into account a number of factors, including: the differences in relative responsibilities; experience and performance in role; the ability to impact overall Company performance; Company, product segment and individual performance; and historical compensation and peer group analyses (used as a reference without benchmarking to a specified target).

There is no minimum amount of variable compensation payable to the NEOs. The Compensation Committee makes determinations, in its discretion, as to the amounts of variable compensation awarded based on program metrics and individual performance, subject to the terms of any applicable plan or arrangement.

Annual Cash Incentives

The Company awards annual cash incentives pursuant to the Company’s AIP, which closely aligns management’s interests with those of shareholders by employing a formulaic approach that considers specific financial metrics and individual goals when determining cash incentives. Under the AIP, each NEO is eligible to earn an annual target cash incentive and may receive between 0% and 150% of their target cash incentive opportunity based on attainment of the level of certain financial performance metrics (together, weighted at 80%) and individual performance (weighted at 20%). The Compensation Committee believes that subjecting 80% of the target cash incentive to pre-established performance targets further promotes shareholder value creation by more directly aligning executive compensation with the Company’s long-term business objectives, financial performance and strategic goal attainment.


72

Compensation Matters

For 2025, the Compensation Committee, with input from shareholders and its independent compensation consultant, refined the AIP’s financial metric weightings to reinforce the Company’s focus on driving sustainable revenue growth and new business generation. The Compensation Committee increased the weighting of Total Net Sales (from 40% to 50%) and Revenue (from 20% to 25%), reflecting its view that accelerating top-line performance is critical to long-term shareholder value creation. The weighting of Adjusted EPS was modestly reduced (from 30% to 25%) while remaining a significant component, ensuring continued focus on profitability and cost discipline. The Compensation Committee also eliminated Free Cash Flow as a standalone metric, reducing the overall number of financial metrics from four to three to enhance simplicity and focus participants on the measures most closely tied to the Company’s strategic priorities.


Metric	2024 Weight		2025 Weight		Change
Total Net Sales	40	%	50	%	+10%
Revenue	20	%	25	%	+5%
Adjusted EPS	30	%	25	%	(5	%)
Free Cash Flow	10	%	—		—
Total Financial	70	%	80	%	+10%

Finally, the Compensation Committee eliminated the individual performance component for sustainability goals (formerly 10%) and refocused the remaining individual performance component on culture and leadership effectiveness (20%) to broaden the focus of the qualitative assessment to encompass cross-functional collaboration and contributions to company culture, modeling cultural values, talent development and demonstration of leadership behaviors.

The following table sets forth the target cash incentive opportunity for each NEO in respect of 2025, as well as the financial and individual performance goal weightings under the AIP for 2025. In 2025, the Compensation Committee did not make any changes to annual target cash incentive compensation for our NEOs compared to 2024.

Beginning in 2026, AIP payouts will be determined entirely by achievement against four financial metrics: Recurring Net New Sales (50% weight), Non-Recurring Sales (10%), Revenue (20%) and Adjusted EPS (20%). Recurring Net New Sales and Non-Recurring Sales will be measured on a quarterly basis, with the final achievement calculated as the average of quarterly results, to reinforce consistent sales execution throughout the year. Payouts for Recurring Net New Sales and Non-Recurring Sales will scale based on performance relative to goals established by the Compensation Committee, with no payout earned for performance below a minimum threshold, and will be measured on a quarterly basis.

Compensation Matters

Financial Component

The threshold, target and maximum for each financial component making up the AIP, as well as the actual results attained for 2025, are included in the table set forth below. The combined actual performance achievement for all metrics under the financial component of the AIP for 2025 was 95.26% of target.


		Threshold				Target				Maximum				Actual

(1)Except adjusted EPS, which is not stated in millions.

(2)For purposes of the AIP, Total Net Sales reflects net new recurring subscription sales plus non-recurring sales weighted at 75%, with annual achievement calculated based on the average of quarterly achievement percentages against a quarterly goal (each quarter’s actual Total Net Sales as a percentage of its quarterly goal). The cumulative annual Total Net Sales target was $290.5 million. The average of the four quarterly achievement percentages resulted in a combined achievement of 82.5% of target. The quarterly goals were derived from the Board-approved annual operating plan and were set at levels the Compensation Committee considered rigorous. The Company has omitted the individual quarterly target goals and achievement percentages underlying this calculation, because this information is competitively and commercially sensitive and the Company believes that disclosure of such information would result in competitive and commercial harm. The quarterly performance goals are used only for internal purposes and we do not otherwise publicly disclose such targets on a quarterly basis. Disclosure of such quarterly targets would reveal detailed information about the Company’s anticipated sales pipeline and operating plan at a level of specificity beyond what we otherwise report externally that could, in turn, provide competitors insight into our business strategy and operations and our approach to forecasting. As a result, competitors could adjust their own operational objectives or take other competitive measures in light of such information. In addition, disclosure of quarterly target levels and achievement rates is commercially sensitive, as clients engaged in pricing and renewal discussion could use such information to infer the Company’s internal sales expectations and related incentive structures. Accordingly, in an effort to balance providing our shareholders with greater visibility into our performance metrics under the AIP with the competitive and commercial concerns noted above, we have presented information regarding our Total Net Sales targets and actual achievement percentages on an annual basis, consistent with the cumulative performance period under the AIP.

Individual Goals Component

The Compensation Committee regularly assesses the individual, non-financial components of the AIP, their weighting and relevant shareholder feedback. For 2025, the Compensation Committee refined the individual goals component for Managing Directors, including our NEOs, to strengthen accountability and provide a more structured approach to assessment. The weighting of financial metrics increased to 80% of the target annual cash bonus (from 70% in 2024), while the individual performance component decreased to 20% (from 30% in 2024, which had been split between individual KPIs (20%) and sustainability goals (10%)).

The Compensation Committee eliminated the standalone sustainability goals component and refocused the remaining individual performance component for members of the Management Committee, including our NEOs, on culture and leadership effectiveness, including cross-functional collaboration and contributions to company culture, modeling cultural values, talent development and demonstration of leadership behaviors. The individual performance component was assessed through the Company’s Executive Accountability Framework. This change was designed to provide a more holistic assessment of each executive’s qualitative contributions.

In 2025, the Compensation Committee based its assessment of each of our NEOs on its evaluation of the Company’s performance and the individual performance of each NEO relating to the following culture and leadership contributions:

Long-Term Equity Incentive Compensation Program

The Compensation Committee believes that MSCI’s executive compensation program should reinforce a pay-for-performance culture that aligns the interests of our senior executives with those of our shareholders by incorporating the achievement of multi-year performance metrics into variable compensation awards (in addition to the annual financial metrics applicable to cash incentive awards under the AIP).

In 2025, the Compensation Committee approved an LTIP that was materially consistent with the program in recent years, which is comprised of (i) PSOs that are earned and vest based on achievement of two equally-weighted performance metrics that are directly linked to the Company’s strategic planning—cumulative revenue and cumulative adjusted EPS—each measured over a cumulative three-year performance period, (ii) PSUs earned based on absolute TSR CAGR over a 3-year performance period and (iii) RSU grants that cliff-vest 100% at the end of a three-year service period (rather than annual ratable vesting over a three-year period).

Additionally, to support our “owner-operator” culture, in 2025 the Compensation Committee continued to include a one-year post-vest mandatory holding period to our annual PSUs, including those that were granted to our NEOs, where such after-tax shares, or rights with respect to such shares, may not be sold, transferred or otherwise disposed of until the expiration of such holding period.

Beginning in 2024, based on feedback received from shareholders, the Compensation Committee reduced the payout maximum under the annual PSUs from 300% to 200% of the target number of shares granted. In addition, the Compensation Committee rebalanced the equity mix (as set forth in the table below) for our NEOs to place greater emphasis on PSOs to highlight the importance of the operating metrics that underlie the performance condition for the PSOs: cumulative revenue and cumulative adjusted EPS. We believe that the cumulative revenue and cumulative adjusted EPS performance metrics will align our executives’ interest with those of our shareholders and drive focus on achievement of longer-term strategic goals.

2025 Equity Mix

The table below sets forth the allocation of 2025 PSUs, PSOs and RSUs granted to the NEOs. As reflected in the table below, in 2025, Mr. Fernandez and Mr. Pettit received 100% of their equity incentive compensation in the form of PSUs and PSOs.


Vehicle	CEO(1)		Former President and COO		Other NEOs
PSUs	30	%	30	%	30	%
PSOs	70	%	70	%	40	%
RSUs	—	%	—	%	30	%

(1)The table above does not reflect a special grant of PPOs to Mr. Fernandez on January 31, 2025, having a total grant date value of $15.0 million in recognition of his role in MSCI’s growth. See page 80 of this Proxy Statement for additional information on Mr. Fernandez’s special PPO award and page 76 of this Proxy Statement for additional information on Mr. Fernandez’s contributions.

In determining the value of 2025 PSUs, PSOs and RSUs, the Compensation Committee took into consideration the executive’s performance and potential future contributions, the executive’s overall career experience, peer group analyses, and the risk profile of the compensation program for the executive. For 2025, the Compensation Committee approved increases in annual long-term incentive compensation for the NEOs after consideration of several factors, including peer group market data and competitive practices.

The table below sets forth the value for each NEO’s annual equity awards for 2025 as approved by the Compensation Committee. Under SEC disclosure rules, we are required to disclose the accounting value for the PSUs, PSOs and RSUs granted to the NEOs in 2025 in “Executive Compensation Tables—Summary Compensation Table” below. As such, the values reflected in the table below may differ from the amounts set forth in the Summary Compensation Table for such awards for 2025.

PSUs

The PSUs granted in 2025 will cliff-vest on January 30, 2028, subject generally to the executive’s continued employment with the Company and the Company’s level of achievement of the applicable absolute TSR CAGR performance metric measured over a three-year performance period. The 2025 PSUs are eligible to vest between 0% and 200% of target. The 2025 PSUs include a one-year post-vest mandatory holding period, where such after-tax shares, or rights with respect to such shares, may not be sold, transferred or otherwise disposed of until the expiration of such holding period.

The table below sets forth the TSR CAGR performance percentage for the 2025 PSUs. There will be interpolation (rounded to two decimal places) to derive a TSR CAGR performance percentage that is not expressly set forth in the table below, and any resulting fractional shares will be rounded down to the nearest whole share.

In 2025, the Compensation Committee also adjusted the applicable TSR performance goal percentages and the applicable threshold, target and maximum goals for the 2025 PSUs to better promote an “owner-operator” culture and focus our senior leaders on long-term shareholder value creation.


TSR CAGR (%)			Performance Percentage (%)
≥ 20.0 (maximum)			200
15.0			150
10.0 (target)			100
1.0 (threshold)			10
< 1.0			No Vesting

The Compensation Committee established the above TSR performance goal percentages applicable to the 2025 PSUs after considering historical 3-year TSR performance of S&P 500 companies and MSCI’s business projections. The Compensation Committee believes that the applicable threshold, target and maximum goals established for the PSU vehicle in 2025 represent rigorous hurdles that would ultimately deliver significant shareholder value creation if achieved, as evidenced by the fact that achievement of the TSR performance goals at the threshold performance levels applicable to the 2025 PSUs would translate to measurable growth in our shareholders’ investments over such performance period.

PSOs

The PSOs granted in 2025 will cliff-vest on January 31, 2028, subject generally to the executive’s continued employment with the Company and the Company’s combined level of achievement of (i) a cumulative revenue performance goal and (ii) a cumulative adjusted EPS performance goal, each weighted equally and measured over a three-year performance period. The specific performance targets underlying the two PSO performance metrics were calibrated to align with MSCI’s long-term strategic planning. Goals are set at the beginning of each year with consideration to historical performance, industry benchmarks, the broader macro-environment and our long-term strategy. Revenue goals support management’s focus on scaling new products and targeting new customer segments. The incorporation of an adjusted EPS goal provides profitability discipline, incorporating considerations relating to capital allocation and shareholder value creation.

The 2025 PSOs are eligible to vest between 0% and 200% of target. Thereafter, participants will only realize value on the number of PSOs earned, if any, to the extent that the closing share price of MSCI common stock exceeds the relevant exercise price of the options. In this way, PSOs have an implied “double-performance” mechanism, as two conditions must be met for a participant to realize value from an award: (i) fundamental operating performance and (ii) share price growth in excess of the exercise price.


			2026 PROXY STATEMENT			79

Compensation Matters

Pursuant to SEC rules, the performance targets underlying the cumulative revenue and cumulative adjusted EPS performance goals applicable to the 2025 PSOs will be disclosed upon the certification of such performance goals in 2028. We do not disclose forward-looking performance goals due to confidentiality and competitive concerns, as we believe the disclosure of forward-looking performance targets that are aligned to our long-term strategic planning could result in competitive harm. We believe that the performance goals were set at challenging levels and are fully aligned with the rigorous expectations and long-term interests of our shareholders. However, consistent with market practice, we have committed to retrospectively disclose the performance goals and payouts following the completion of the relevant performance period. Our shareholders have generally provided the feedback that they understand and are comfortable with this approach.

RSUs

RSUs are inherently aligned with the interest of our shareholders because they are linked to share price appreciation. They also increase the retentive value of our overall compensation program. The RSUs granted in 2025 will cliff-vest on January 31, 2028, subject generally to the executive’s continued employment with the Company. While these RSU awards for 2025 do not have explicit performance-vesting conditions, the ultimate value that will be delivered to our NEOs from these awards depends on our future share price performance.

2025 Special Premium-Priced Stock Option CEO Award

On January 31, 2025, the Compensation Committee granted a special PPO award for our Chairman and CEO, Henry A. Fernandez, having a total grant date value of $15.0 million. The PPOs are allocated across three equal tranches with rigorous exercise prices of $1,000, $1,100, and $1,200—representing significant premiums of approximately 69.3%, 86.2% and 103.1%, respectively, to the closing share price on the day prior to grant date.

The Compensation Committee deliberately chose premium-priced stock options over full-value equity awards such as restricted stock units. Unlike full-value awards, PPOs deliver zero value unless the Company’s share price exceeds the exercise price hurdle. Even then, Mr. Fernandez participates only in the incremental appreciation above that hurdle, creating meaningful risk that some or all of the PPOs could expire without delivering any value.

The options vest on the fifth anniversary of the grant date, subject to Mr. Fernandez’s continued service (except in limited circumstances involving a termination of employment without cause or due to death or disability). Unlike the Company’s historical equity incentive compensation program, the award does not provide for interim or retirement vesting; accordingly, the entirety of the award remains at risk and contingent on Mr. Fernandez’s continued service through the end of the five-year vesting period. The award is subject to the Company’s compensation recoupment policies and stock ownership guidelines (under which Mr. Fernandez must maintain 25% of net shares realized following any stock option exercise) and, as a special award, is not part of the Company’s regular annual compensation program.

Transformational Share Price Growth Required to Unlock Any Award Value

The chart below compares MSCI’s share price since our 2007 IPO with the exercise price hurdles, illustrating the share price appreciation required for the PPOs to deliver any value by the January 2030 vesting date.

Shareholder Value Created at Premium Exercise Price Hurdles(1)

The chart below illustrates the market capitalization growth shareholders would realize at each of the PPO exercise price hurdles, compared to the Company’s $43.2 billion market capitalization on the trading day prior to the grant date.

04_MSCI_Market Capitalization Growth from Grant Date.jpg



			Share Price Rigor: MSCI’s stock would have to appreciate at a compound annual rate of approximately +11% over five years to reach $1,000—only above that price level would 1/3 of Mr. Fernandez’s options begin to share in value creation on the vesting date. Shareholder-First Design: At the highest exercise price hurdle of $1,200, shareholders would realize $44.5 billion in market capitalization growth. Even then, Mr. Fernandez’s participation would represent approximately 0.0257% of the value created for shareholders.


			2026 PROXY STATEMENT			81

Compensation Matters

(1)Market capitalization in the chart above calculated assuming 73,120,206 common shares outstanding as of February 27, 2026. The market capitalization was $43.2 billion on the trading day prior to the grant date (with a closing share price of $590.73). The award consists of premium-priced stock options with exercise prices of $1,000, $1,100, and $1,200. At the $1,200 exercise price, the aggregate in-the-money value of the award would be approximately $11.4 million, representing approximately 0.0257% of the $44.5 billion in market capitalization growth shareholders would realize at that price.

Factors Considered by the Board in Approving the Award

In approving the special PPO award, the Compensation Committee considered a range of factors, including the Company’s ongoing dialogue with shareholders regarding its compensation program, as described under “Shareholder Engagement” on page 41 above. The award to Mr. Fernandez reflects the Company’s commitment to an “owner-operator” culture by using an equity award that directly links pay to long-term shareholder value creation, while rewarding exceptional leadership and sustained contributions to MSCI’s growth. The Compensation Committee, in consultation with Semler Brossy, its independent compensation consultant, and review by the independent members of the Board, determined to strengthen Mr. Fernandez’s alignment with the Company’s long-term growth priorities through value-creating incentives, based on rigorous and extraordinarily hard-to-achieve share price hurdles. Mr. Fernandez did not participate in any deliberations regarding the award.

In approving the award, the Compensation Committee considered the following:

•Mr. Fernandez’s proven track record of value creation: Mr. Fernandez oversaw MSCI’s growth over 25 years as the Company’s CEO, during which the Company’s share price increased more than 37-fold under his leadership from its initial public offering in 2007 through year-end 2024. This performance reflects a total shareholder return compound annual growth rate (“CAGR”) of 23.5%, significantly exceeding the S&P 500 index CAGR of 10.6% over the same period.

•The strategic imperative to sustain MSCI’s growth trajectory: The Compensation Committee recognized the importance of incentivizing MSCI’s growth amid the rapidly developing changes in the investment industry, including advancements in technology, increasing demand for customized portfolio construction tools and growing investor interest in private assets, among other evolving industry trends, and increasingly intense competition for top executive talent.

•Peer compensation practices: In consultation with its independent compensation consultant, the Compensation Committee reviewed an in-depth analysis of compensation practices among the Company’s peers and CEO pay opportunities and the performance-based weighting of CEO pay within the Company’s peer group.

•Share price performance as the core metric of successful execution of MSCI’s strategic priorities: The Compensation Committee considered various award structures and determined that premium-priced stock options best reflected the Compensation Committee’s objectives. Unlike other performance awards we grant under the LTIP, the performance hurdles of the PPOs are fixed into the exercise price—meaning even after the stock price hurdle is satisfied, Mr. Fernandez will only realize value to the extent our share price continues to appreciate thereafter. As a result, there is meaningful risk that some or all of the PPOs could result in zero realizable value if the Company’s share price does not reach and sustain the premium exercise price thresholds. The Compensation Committee believes this rigorous performance structure further aligns Mr. Fernandez’s interest with those of our shareholders.

•Strong long-term alignment with shareholders: The award is designed to reinforce long-term shareholder alignment through a five-year vesting period, without interim vesting opportunities and premium exercise prices that deliver zero value unless MSCI’s share price appreciates meaningfully above the closing share price on the trading day prior to grant date. Given that Mr. Fernandez is already one of the Company’s largest individual shareholders, the Compensation Committee structured the award to reward only exceptional future performance rather than provide incremental value tied to the Company’s current valuation.

•Robust retention and ownership requirements: The award is also subject to the Company’s existing stock retention requirements, under which Mr. Fernandez must maintain 25% of net shares realized following any stock option exercise through the end of his service on the Management Committee. These retention requirements apply in addition to the Company’s stock ownership guidelines, which require Mr. Fernandez to hold shares equivalent to twelve times his annual base salary.

•This special award is not part of our regular compensation program. The Compensation Committee determined the award was warranted by the specific strategic circumstances facing the Company, including the need for enhanced leadership continuity and focused execution during a pivotal period of market transformation.

Shareholder Engagement

As part of our 2025 Corporate Responsibility off-season engagement, we engaged with shareholders representing approximately 27.1% of our outstanding shares on the design and rationale of the CEO special incentive award. Investors who met with us broadly acknowledged the importance of incentivizing continued contributions of Mr. Fernandez during this critical period of industry transformation and viewed positively the structure of the award. Investors specifically cited the rigor of the premium exercise price hurdles and expressed comfort with the award’s structure, noting that the significant premiums to the closing share price on the trading day prior to grant date ensure that Mr. Fernandez participates in value creation only after shareholders have realized substantial appreciation. Several investors highlighted that they view premium-priced options as carrying meaningful additional risk compared to at-the-money awards and that the performance thresholds embedded in the exercise prices are robust. See page 41 of this Proxy Statement for additional information regarding our shareholder engagement efforts in 2025.

For a description of the treatment of these awards upon a termination of employment or a change in control, see “Potential Payments Upon Termination or Change in Control” on page 95 of this Proxy Statement.

The grant date fair value of the award is reflected in the 2025 Summary Compensation Table and in the Grants of Plan-Based Awards table. The Compensation Committee notes that grant date accounting value is not indicative of the value ultimately realizable by the participant, which depends on future share price performance above the exercise prices.

2021 PSU Award Payouts

The five-year performance period applicable to the PSUs granted to each of Messrs. Fernandez, Wiechmann, Pettit, Munari and Crum commenced on February 3, 2021 and concluded on February 2, 2026. The 2021 PSUs required a TSR CAGR of at least 10.00% to achieve threshold performance level (50% of opportunity), 12.50% to achieve target performance level (100% of opportunity), and 20.00% to achieve maximum performance level (200% of opportunity). The TSR CAGR achievement was below threshold performance level, resulting in no payout for the 5-year PSUs granted to each of Messrs. Fernandez, Wiechmann, Pettit, Munari and Crum on February 4, 2021. For more information on the threshold, target and maximum goals applicable to the 2021 PSUs, please see page 81 of our 2022 Proxy Statement.

2023 PSU Award Payouts

The three-year performance period applicable to the PSUs granted to each of Messrs. Fernandez, Wiechmann, Pettit, Munari and Crum commenced on February 2, 2023 and concluded on February 1, 2026. The 2023 PSUs required a TSR CAGR of at least 8.00% to achieve threshold performance level (25% of opportunity), 10.00% to achieve target performance level (100% of opportunity), and 30.00% to achieve maximum performance level (300% of opportunity). The TSR CAGR achievement was below threshold performance level, resulting in no payout for the 3-year PSUs granted to each of Messrs. Fernandez, Wiechmann, Pettit, Munari and Crum on February 2, 2023. For more information on the threshold, target and maximum goals applicable to the 2023 PSUs, please see page 77 of our 2024 Proxy Statement.

2023 PSO Award Payouts

The three-year performance period applicable to the PSOs granted to each of Messrs. Fernandez, Wiechmann, Pettit, Munari and Crum on January 1, 2023 concluded on December 31, 2025, and the service condition was satisfied on February 2, 2026, and resulted in the following level of achievement:


	Performance Period: 2023-2025
	Threshold				Target				Maximum				Actual

Compensation Matters

Actual achievement of the cumulative revenue performance metric was 51.1% and the adjusted EPS performance metric was 100.0%, which resulted in a payout of 151.1% of the target number of PSOs. Following the performance certified by the Compensation Committee, Mr. Fernandez received 42,193 options to purchase common stock, Mr. Wiechmann received 5,639 options, Mr. Pettit received 23,781 options, Mr. Munari received 6,042 options and Mr. Crum received 4,968 options, all of which vested and became exercisable on February 2, 2026.

2026 Long-Term Equity Incentive Compensation Program

The Compensation Committee approved the 2026 LTIP to align NEO interests with long-term shareholder value and to reinforce MSCI’s owner-operator culture. The LTIP continued to consist of annual PSUs, PSOs and RSUs, with the majority of long-term incentive value delivered through performance-based awards; the CEO’s 2026 LTIP awards were entirely performance based.

PSUs and PSOs remained the principal performance vehicles for long-term pay. PSUs continued to be measured using multi-year absolute TSR metrics with a 0% payout below threshold and up to 200% at maximum; PSOs continued to tie payout to multi-year cumulative revenue and adjusted EPS goals. The Compensation Committee approved these designs after consideration of peer practice, shareholder feedback and MSCI’s strategic and talent priorities.

For 2026, the Compensation Committee retained three-year cliff vesting for RSUs but introduced an upside-only RNN performance modifier measured over FY2026. The RNN performance modifier could increase the number of RSUs granted up to 130% if the RNN metric is achieved, but would not reduce the number of RSUs below 100% if it is not achieved. RNN is measured as net new recurring subscription sales (new recurring subscription sales minus subscription cancellations).

2026 Equity Mix

The table below sets forth the allocation of 2026 PSUs, PSOs and RSUs granted to the NEOs. In connection with his transition to an advisory role effective March 1, 2026, Mr. Pettit was not eligible to receive 2026 equity awards. Please see page 78 for the allocation of 2025 PSUs, PSOs and RSUs granted to the NEOs.

Benefits

The Company provides health, welfare and other benefits to remain competitive in hiring and retaining its employees. Our NEOs are eligible to participate in these benefit plans on the same terms and conditions as all other employees. We do not provide any special or enhanced benefits to our NEOs.

In the United States and the United Kingdom, the Company has established defined contribution plans for all eligible employees. Contributions by the Company to these defined contribution plans for our NEOs for the applicable period are disclosed in the “All Other Compensation” column in the Summary Compensation Table below.

Employment Agreements

All of the NEOs are employed on an “at-will” basis, and the Company does not have any individual employment agreements with the NEOs providing for a fixed duration of employment. As a result, the Company has the flexibility to alter or revise its compensation programs as circumstances dictate.

Mr. Wiechmann’s Offer Letter and Mr. Pettit’s Employment Letters

Under Mr. Wiechmann’s offer letter with the Company and Mr. Pettit’s employment letter with a subsidiary of the Company, in the event of an involuntary termination of employment without cause, each of Messrs. Wiechmann and Pettit is eligible to receive, subject to his compliance with certain conditions, (i) a lump sum cash payment equal to the sum of his then-current annual base salary plus target annual bonus opportunity and (ii) a prorated cash bonus under the AIP for the year of termination based on actual performance through the date of termination (as of December 31, 2025, assuming 100% achievement of the annual bonus opportunity, such amounts would have equaled $2,100,000 for Mr. Wiechmann and $3,197,106 for Mr. Pettit; the amount for Mr. Pettit is shown as being paid in British pounds sterling and converted to U.S. dollars using the fiscal year average of daily spot rates of £1 to $1.3184 for fiscal 2025).

Transition Arrangements with Mr. Pettit

Mr. Pettit ceased serving in his position as President and as a member of the Board of Directors effective March 1, 2026 and transitioned to an advisory role with the Company as of such date. In connection with his transition of services, Mr. Pettit entered into a Transition and Advisory Agreement with MSCI Inc. (the “Advisory Agreement”) and a Settlement Agreement with MSCI Limited, each dated January 28, 2026. Under these agreements, Mr. Pettit serves as a senior advisor to the Chief Executive Officer from March 1, 2026 through August 15, 2026 at a monthly advisory fee of £20,000, and will continue to vest in his outstanding equity awards through his service termination date. Under the Settlement Agreement, Mr. Pettit waived his entitlement to severance benefits under his employment letter with MSCI Limited, including the severance practice described therein. Under the Advisory Agreement, Mr. Pettit remains subject to customary confidentiality obligations and restrictive covenants.

In addition, we maintain a Change in Control Severance Plan for the benefit of eligible senior executives of the Company (including the NEOs) that provides for severance benefits on a “double-trigger” basis—i.e., in the event of a qualifying termination of the executive’s employment by the Company without “cause” or by the participant for “good reason” in connection with a change in control.

Additional information on post-termination and change in control benefits for our NEOs, assuming a qualifying event occurred as of December 31, 2025, is provided in the section titled “Potential Payments upon Termination or Change in Control,” on page 95 of this Proxy Statement.

No Excessive Perquisites

Based on the Company’s philosophy that its executive compensation program should be straightforward and directly linked to performance, the compensation program for the NEOs does not include any excessive perquisites, excise tax gross-ups or supplemental executive retirement benefits.

Stock Ownership Guidelines

The Compensation Committee believes that significant stock ownership at the Management Committee level, among MSCI’s senior-most leadership, which includes our NEOs, aligns management’s interests with those of our shareholders and encourages an “owner-operator” mindset. As part of the Compensation Committee’s ongoing assessment of the Company’s compensation policies and practices to ensure furtherance of the goals identified above and for alignment with best practices, effective January 1, 2019, the Compensation Committee adopted stock ownership guidelines.

Our stock ownership guidelines reflect among the highest multiples of base salary in our peer group, as detailed below. As of the date of this Proxy Statement, all Management Committee members, including our NEOs, are in compliance with the current stock ownership guidelines. Our CEO significantly exceeds his applicable stock ownership guidelines (see page 109 of this Proxy Statement for additional details).


Position			Stock Ownership Guidelines
Chief Executive Officer			12x base salary
Other Management Committee Members, including other NEOs			8x base salary

All Management Committee members are required to meet the applicable ownership guidelines under the current stock ownership guidelines within five years following the date of such executive’s appointment to the Management Committee. For the purpose of determining whether each individual is in compliance with these stock ownership guidelines and requirements, the following are counted towards satisfaction of the minimum ownership requirements:

1.shares beneficially owned individually, directly or indirectly;

2.shares beneficially owned jointly with, or separately by, immediate family members residing in the same household, either directly or indirectly; and

3.shares underlying unvested RSUs.

Unexercised stock options and unearned performance awards do not count toward satisfaction of the minimum ownership requirements.

Until the expected ownership levels are achieved, each Management Committee member is required to retain 50% of the Net Shares resulting from the vesting, settlement or exercise, as applicable, of all PSUs, stock options, RSUs or other equity awards granted to such executive.

In addition to the minimum ownership requirements, the share retention requirements of the stock ownership guidelines provide that until an executive ceases to serve on the Company’s Management Committee, such executive will be required to retain a number of shares equivalent to, in the aggregate, 25% of the “Net Shares” resulting from the vesting, settlement or exercise, as applicable, of all equity incentive awards granted to such executive after January 1, 2022 (or, if later, the date such executive becomes a member of the Management Committee). The Compensation Committee determined that the addition of this 25% “Net Shares” holding requirement would further enhance our goal of reinforcing an “owner-operator” mindset among senior leaders. This approach will ensure that a portion of the Net Shares received from every award will be retained while an individual serves on the Management Committee.

Equity Award Timing

Although we do not have a formal policy with respect to the timing of grants of our LTIP awards, the Compensation Committee has historically granted such awards on a predetermined annual schedule, following its January meeting each year. We also periodically grant off-cycle LTIP awards in connection with specific circumstances such as new hires, promotions, retention efforts or as replacement grants.

The Company has never granted, and has no plans to grant, any LTIP award to current or new employees in anticipation of the release of material nonpublic information, and we do not accelerate or delay the release of material nonpublic information based on equity award grant dates or for the purpose of affecting the value of executive compensation. The Company does not backdate stock options or restricted stock units. The exercise price of stock options is no less than the closing price of MSCI stock on the effective date of the grant.

During 2025, no equity awards were granted to named executive officers within four business days preceding or one business day after the filing of any Form 10-K, 10-Q or 8-K disclosing material nonpublic information.

Other Policies

Clawback Policies

We seek to recover, to the extent practicable, performance-based compensation from members of our Management Committee and the Company’s Principal Accounting Officer under certain circumstances. In 2023, the Board adopted the Company’s Financial Statement Compensation Recoupment Policy in accordance with Rule 10D-1 and revised its Management Committee Compensation Recoupment Policy. Under the Company’s Financial Statement Compensation Recoupment Policy, the Compensation Committee, will, to the extent permitted by law, recoup any incentive compensation (cash and equity) received by the Company’s Executive Officers, in the event of a restatement of financial-based measures (regardless of whether detrimental conduct has occurred). In the case of a restatement of financial-based measures, the Compensation Committee will reasonably promptly recover the amount by which the incentive compensation received exceeds the amount that would have been received if the error had not been made within the three years preceding the date on which the Board determines that the financial measure contains a material error.

Under the Company’s revised Management Committee Compensation Recoupment Policy, the Compensation Committee may, to the extent permitted by applicable law, recoup any incentive compensation (cash and equity) received by members of the Company’s Management Committee and the Company’s Principal Accounting Officer in the event of a restatement of financial or other performance-based measures (regardless of whether detrimental conduct has occurred) or in the event that detrimental conduct results in an increased level of performance goal achievement or otherwise causes material financial and/or reputational harm to the Company, as described below. In the case of a restatement of financial or other performance-based measures, the Compensation Committee may recover up to the amount by which the incentive compensation received exceeds the amount that would have been received if the error had not been made within the two years preceding the date on which the Board or the Compensation Committee determines that the financial or other measure contains a material error.

Under the Company’s revised Management Committee Compensation Recoupment Policy, in the case of detrimental conduct that, in the sole discretion of the Compensation Committee, has resulted in a level of achievement of a performance-based measure or caused material financial or reputational harm to the Company, the Board may recover incentive compensation, including service-vesting awards, received by the person during the two-year period immediately preceding the date on which such person engaged in such detrimental conduct (or the date on which the Compensation Committee discovers that such person engaged in detrimental conduct). Detrimental conduct consists of:

•willful misconduct or breach of a fiduciary duty with respect to the Company or any of its subsidiaries;

•conviction of, or having entered a plea bargain or settlement admitting guilt for, any crime of moral turpitude or felony under any applicable law with respect to the Company or any of its subsidiaries;

•commission of an act of fraud, embezzlement or misappropriation, with respect to the Company or any of its subsidiaries;

•breach of any restrictive covenant to which such person is subject contained in any applicable agreement or arrangement with the Company or any of its subsidiaries; and

•failure to take action with respect to any acts or conduct described above when taken by another person that such person has actual knowledge of or directing any other person to take any of the actions described above.

The Management Committee Compensation Recoupment Policy applies to all incentive compensation (cash and equity, including service-vesting awards in the case of detrimental conduct) granted on or after February 7, 2019. The Financial Statement Compensation Recoupment Policy applies to all incentive compensation (cash and equity) that is determined based on goals attained in any of the three completed fiscal years (i.e., compensation is “received”), beginning with the fiscal year ended December 31, 2023.

Anti-Hedging and Anti-Pledging Policy

We prohibit all directors and employees, including all NEOs, from hedging or pledging the Company’s common stock or engaging in short sales, purchases or sales of options, puts or calls, as well as derivatives such as swaps, forwards or futures and trading on a short-term basis in the Company’s common stock.

Tax Considerations

The Compensation Committee takes into consideration the tax implications of our executive compensation program, including with respect to the tax deductibility of compensation paid under Section 162(m) of the Internal Revenue Code.

In the exercise of its business judgment, and in accordance with its compensation philosophy, the Compensation Committee continues to have flexibility to award compensation that is not tax deductible if it determines that such award is in our shareholders’ best interests and is necessary to comply with contractual commitments, or to maintain flexibility needed to attract talent, promote retention or recognize and reward desired performance.

Compensation Risk Assessment

The Compensation Committee believes that the design, implementation and governance of our executive compensation program are consistent with high standards of risk management. Our executive compensation program reflects an appropriate mix of compensation elements, balancing current and long-term performance objectives, cash and equity compensation, and risks and rewards.

•The compensation framework used for making compensation decisions is multi-faceted as it incorporates multiple metrics, including company-wide financial measures and stock price performance, over varying time periods and is subject to the application of informed judgment by the Compensation Committee.

•To further ensure that the interests of our NEOs are aligned with those of our shareholders, a significant portion of executive officer long-term incentive compensation is awarded as equity, delivered through a mix of PSUs, PSOs and RSUs, subject to vesting requirements. Awards vest over a multi-year period, and in the case of performance-based awards, vest based on achievement of applicable performance goals at the end of a relevant performance period.

•Management Committee members are required to meet the applicable stock ownership guidelines described under “Stock Ownership Guidelines” on page 86 of this Proxy Statement.

•Incentive compensation is subject to the clawback policies described under “Clawback Policies” on page 87 of this Proxy Statement.

Based on these features, we believe our executive compensation program effectively (i) ensures that our compensation opportunities do not encourage excessive risk taking, (ii) keeps our NEOs focused on the creation of long-term, sustainable value for our shareholders and (iii) provides competitive and appropriate levels of compensation over time.

In 2025, the Compensation Committee, with the assistance of its independent compensation consultant, reviewed our compensation practices and policies as generally applicable to all of our employees and believes that our practices and policies do not encourage excessive or unnecessary risk-taking and that any level of risk they do encourage is not reasonably likely to have a material adverse effect on the Company.

In connection with its 2025 assessment, the Compensation Committee also engaged Aon to evaluate the Company’s executive, broad-based and client-coverage compensation programs from a risk and governance perspective. Aon concluded that the Company’s 2025 executive, broad-based, and client-coverage incentive compensation policies and practices are not reasonably likely to promote excessive risk-taking behavior or to have a material adverse effect on the Company.

Potential Payments upon Termination or Change in Control

Change in Control Severance Plan

In the event of a change in control of the Company, Management Committee members, including all of our NEOs, would be entitled to benefits under the MSCI Inc. Change in Control Severance Plan (the “CIC Plan”), which was adopted by the Board of Directors in May 2015 and amended in February 2026. The CIC Plan covers participants identified on a schedule attached to the CIC Plan (subject to any additions to or removals from the participant list by the Compensation Committee), including the Company’s CEO, CFO and the Company’s other NEOs. In the event of a “Qualifying Termination” (for certain terminations related to changes in control, as defined in the CIC Plan), participants will receive the severance payments and benefits specified in the CIC Plan. Severance payments and benefits under the CIC Plan are subject to a “double-trigger” as both a change in control and a termination of the participant’s employment by the Company without “cause” or by the participant for “good reason” (as such terms are defined in the CIC Plan) are required in order for the participant to qualify for payments and benefits. The CIC Plan does not include any golden parachute excise tax gross-up provisions. Any severance payments and benefits under the CIC Plan are subject to execution of an agreement by the CIC Plan participant releasing claims against the Company. Participants are also obligated to comply with confidentiality, non-solicitation and non-disparagement covenants under their release agreement.

Annual Incentive Plan

In the event of a change in control (as defined in the AIP), unless otherwise determined by the Compensation Committee, the performance period applicable to any outstanding AIP cash bonus award will cease as of the date immediately prior to the change in control. The portion of any such award based on performance metrics (other than individual goals and metrics) will be payable based on the higher of (i) the Company’s actual achievement of the performance metrics (other than individual goals and metrics) for the prorated period ending immediately prior to the change in control and (ii) 100%. The portion of any such award based on individual goals and metrics will be payable at 100% of the target. All awards will be payable by the Company (or the successor or survivor entity) within 60 days of the date of the change in control, prorated for the portion of the applicable performance period that elapsed prior to the change in control.

If the Company’s successor will not be implementing a comparable annual incentive plan for the remaining portion of the year in which the change in control occurs, the Compensation Committee may, in its discretion, elect not to prorate the awards. If any AIP participant is eligible to receive a prorated annual bonus for the year in which the change in control occurs pursuant to any other change in control severance plan, including the CIC Plan, the individual’s prorated annual bonus payable under such other plan will be reduced by the amount of the bonus paid under the AIP.

Equity Acceleration

The descriptions of equity acceleration provisions below apply to the applicable outstanding equity awards as of December 31, 2025.

Terminations Other Than Due to Death, Disability, Involuntary Termination Without Cause or Retirement

Upon termination of an NEO’s employment for any reason other than due to death, disability, involuntary termination without cause or retirement (as such terms are defined in the applicable award agreement), his or her unvested PSUs, PSOs, RSUs and PPOs will generally be cancelled immediately. Equity awards granted to NEOs who are eligible for retirement treatment are cancelled following a termination for cause.

Death or Disability

Upon termination of an NEO’s employment due to death or “disability” (as defined in the applicable award agreement):

•PSUs. PSUs will vest and convert into shares on the adjustment date, subject to adjustment based on actual performance through the end of the performance period.

•PSOs. The service condition will be deemed fully satisfied on the termination date, and the number of PSOs that will become vested options will be determined based on actual performance through the end of the performance period

•RSUs. RSUs will vest and convert into shares within 30 days of the termination date.

•PPOs. PPOs vest and become fully exercisable on the termination date.

Involuntary Termination

If the Company terminates an NEO’s employment without “cause” (as defined in the applicable award agreement) and he or she signs and does not revoke an agreement and release of claims satisfactory to the Company within 60 days of the termination date:

•2023, 2024 and 2025 3-Year PSUs. A prorated portion of the target number of PSUs will vest and convert into shares on the adjustment date equal to the product of (i) the target number of PSUs multiplied by (ii) a fraction, (A) the numerator of which is the total number of months the NEO was employed by the Company during the 3-year performance period (rounded up to the next whole month), and (B) the denominator of which is 36 months, subject to adjustment based on actual performance through the end of the performance period. However, for NEOs who have achieved “62/10 Retirement Eligibility,” all of the target PSUs (i.e., not prorated) will vest and convert into shares on the adjustment date, subject to adjustment based on actual performance through the end of the performance period.

•2021 5-Year PSUs. If the termination of employment occurs prior to the second anniversary of the grant date, the PSUs will be forfeited in their entirety. Following the second anniversary of the grant date, a prorated portion of the target number of PSUs will vest and convert into shares on the adjustment date equal to the product of (i) the target number of PSUs multiplied by (ii) a fraction, (A) the numerator of which is the total number of months the NEO was employed by the Company during the 5-year performance period (rounded up to the next whole month), and (B) the denominator of which is 60 months, subject to adjustment based on actual performance through the end of the performance period. However, for NEOs who have achieved “62/10 Retirement Eligibility,” all of the target PSUs (i.e., not prorated) will vest and convert into shares on the adjustment date, subject to adjustment based on actual performance through the end of the performance period.


96

Compensation Matters

•PSOs. A prorated portion of the service condition will be deemed satisfied determined by dividing (i) the total number of months the NEO was employed by the Company during the vesting period (rounded up for partial months) by (ii) 36 months. The number of prorated PSOs that become vested options (if any) will be determined based on actual performance through the end of the performance period. However, for NEOs who have achieved “62/10 Retirement Eligibility,” (i) the service condition will be deemed fully satisfied on the termination date and (ii) the number of PSOs that become vested options (if any) will be determined based on actual performance through the end of the performance period.

•RSUs. A prorated portion of the RSUs will vest and convert to shares on the vesting date equal to the product of (i) the total number of RSUs granted pursuant to the award multiplied by (ii) a fraction, (A) the numerator of which is the total number of months the NEO was employed by the Company during the vesting period (rounded up to the next whole month) and (B) the denominator of which is 36 months. However, for NEOs who have achieved “62/10 Retirement Eligibility” (as defined in the applicable award agreement), the RSUs will fully vest on the date of termination and will convert to shares on the original payment schedule.

•PPOs. If the termination of employment occurs prior to the third anniversary of the grant date, a prorated portion of the PPOs will vest, determined by dividing (i) the total number of months Mr. Fernandez was providing services to the Company between the grant date and the termination date (rounded up for partial months) by (ii) 36 months. Following the third anniversary of the grant date, the PPOs will be fully vested on the termination date.

Retirement

Upon termination of an NEO’s employment in circumstances that makes him or her eligible for retirement treatment (based on the applicable award agreement):

•PSUs. For NEOs who have achieved “Legacy Retirement Eligibility” or “55/10 Retirement Eligibility” but who have not achieved “62/10 Retirement Eligibility,” a prorated portion of the target number of PSUs will vest and convert to shares on the adjustment date equal to the product of (i) the target number of PSUs multiplied by (ii) a fraction, (A) the numerator of which is the total number of months the NEO was employed by the Company during the 3- or 5-year performance period, as applicable (rounded up to the next whole month), and (B) the denominator of which is 36 or 60 months, as applicable, subject to adjustment based on actual performance through the end of the performance period. However, for NEOs who have achieved “62/10 Retirement Eligibility,” all of the target PSUs (i.e., not prorated) will vest and convert into shares on the adjustment date, subject to adjustment based on actual performance through the end of the performance period.

•PSOs. For NEOs who have achieved “Legacy Retirement Eligibility” or “55/10 Retirement Eligibility” but who have not achieved “62/10 Retirement Eligibility,” a prorated portion of the service condition will be deemed satisfied determined by dividing (i) the total number of months the NEO was employed by the Company during the 3-year performance vesting period (rounded up for partial months) by (ii) 36 months. The number of prorated PSOs that become vested options (if any) will be determined based on actual performance through the end of the performance period. For NEOs who have achieved “62/10 Retirement Termination” (as such term is defined in the applicable award agreement), the service condition will be deemed fully satisfied and the number of PSOs that become vested options (if any) will be determined by actual performance through the end of the performance period.

•RSUs. For NEOs who have achieved “Legacy Retirement Eligibility” or “55/10 Retirement Eligibility” (as such terms are defined in the applicable award agreement) but who have not achieved “62/10 Retirement Eligibility,” a prorated portion of the RSUs will vest and convert to shares on the next regularly scheduled vesting date equal to the product of (i) the total number of RSUs granted pursuant to the award multiplied by (ii) a fraction, (A) the numerator of which is the total number of months the NEO was employed by the Company during the vesting period (rounded up to the next whole month) and (B) the denominator of which is 36 months. For NEOs who have achieved “62/10 Retirement Eligibility,” the RSUs will fully vest on the date of termination and will convert to shares on the original payment schedule.

•PPOs. There is no retirement treatment. The PPOs will be forfeited in their entirety upon any retirement termination.

Change in Control

In the event an NEO’s employment is terminated by MSCI without “cause” or by him or her for “good reason,” in each case, within 24 months following a “change in control” (as such terms are defined in the applicable award agreement):

•PSUs. PSUs will vest and convert to shares within 60 days of the date of termination of employment, and the performance metrics will be deemed to have been achieved at the greater of (i) the actual achievement of the performance metrics for the period commencing on the first day of the performance period and ending on the date immediately prior to the change in control and (ii) 100%.

•PSOs. PSOs will vest and become exercisable and the performance condition will be deemed to have been achieved at the greater of (i) the actual achievement of the performance condition for the period commencing on the first day of the performance period and ending on the date immediately prior to the change in control and (ii) 100%.

•RSUs. RSUs will vest and convert into shares within 60 days of the date of termination of employment.

•PPOs. PPOs will vest and become exercisable within 60 days of the date of termination of employment.

Upon a “change in control,” if the applicable awards are not assumed or continued by the acquiror, the awards will vest in full (with applicable performance conditions deemed achieved at the greater of target and actual performance), regardless of whether the NEO experiences a qualifying termination of employment as described above.

The following table represents the amounts to which our NEOs or their estates or representatives, as applicable, would have been entitled to receive had their employment been terminated on December 31, 2025 or had a change in control occurred on December 31, 2025.

CEO Pay Ratio

In accordance with the requirements of Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K (collectively, the “Pay Ratio Rule”), we are providing the following estimated information for 2025:

•the median of the annual total compensation of all our employees (except our Chief Executive Officer) was $56,294;

•the annual total compensation of our Chief Executive Officer was $33,320,590, or $18,320,508 excluding the special PPO award described on page 80 of this Proxy Statement; and

•the ratio of these two amounts was 592(1) to 1, or 325(2) to 1 excluding the special PPO award. We believe that this ratio is a reasonable estimate calculated in a manner consistent with the requirements of the Pay Ratio Rule.

SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and apply various assumptions and, as a result, the pay ratio reported by us may not be comparable to the pay ratio reported by other companies.


			2026 PROXY STATEMENT			99

Compensation Matters

(1)For purposes of the CEO pay ratio disclosure, Mr. Fernandez’s annual total compensation includes the amount reported in the “Total” column of the Summary Compensation Table on page 90 of this Proxy Statement, including the special PPO award granted to Mr. Fernandez in early 2025, having a total grant date value of $15.0 million.

(2)We understand that the CEO pay ratio is intended to provide greater transparency to annual CEO compensation and how it compares to the annual compensation of the median employee. As such, we are providing a supplemental ratio that compares the CEO’s total 2025 compensation, excluding the special PPO award with a grant date fair value of $15,000,082 described on page 80 of this Proxy Statement, to the annual total compensation of the median employee to facilitate a better understanding of our CEO’s ongoing annual total compensation and better comparability.

Methodology for Identifying our “Median Employee”

Employee Population

To identify the median of the annual total compensation of all our employees (other than our Chief Executive Officer), we first identified our total employee population from which we determined our “median employee.” We determined that, as of December 31, 2025, our total employee population consisted of 6,268 individuals (of which 51% of MSCI employees were located in the Asia Pacific region, 24% in Europe, Middle East and Africa, 16% in the United States and Canada, and 9% in Mexico and Brazil). Our total employee population consisted of our global workforce of full-time and part-time employees, as described in more detail below.

Determining our Median Employee

To identify our “median employee” from our total employee population, as of December 31, 2025, we compared the amount of base salary plus actual cash bonus paid for 2025. In making this determination, we annualized the compensation of our full-time employees who were hired in 2025 but did not work for us for the entire fiscal year and permanent part-time employees. We identified our “median employee” using this compensation measure, which was consistently applied to all our employees included in the calculation.

Our Median Employee

Using the methodologies described above, we determined that our “median employee” was a full-time, salaried employee located in Pune, India, with base salary plus actual cash bonus paid for the 12-month period ending December 31, 2025 in the amount of $50,461.

Determination of Annual Total Compensation of our “Median Employee” and our CEO

Once we identified our “median employee,” we then calculated such employee’s annual total compensation for 2025 using the same methodology we used for purposes of determining the annual total compensation of our NEOs for 2025 (as set forth in the Summary Compensation Table for 2025 on page 90 of this Proxy Statement).

Pay Versus Performance

The following table sets forth the compensation for our CEO and the average compensation for our other NEOs, both as reported in the Summary Compensation Table on page 90 of this Proxy Statement and with certain adjustments to reflect the “compensation actually paid” to such individuals, as defined under SEC rules, for each of 2025, 2024, 2023, 2022 and 2021. “Compensation Actually Paid” does not represent cash or equity value realized or paid to our NEOs or how our Compensation Committee evaluates compensation decisions, but rather is a value calculated based on the requirements and methodology set forth in the applicable SEC rules. The table also provides information on our cumulative total shareholder return (“TSR”), the cumulative TSR of our peer group, net income and adjusted EPS.

(1)Compensation for our principal executive officer (“PEO”), Henry A. Fernandez, reflects the amounts reported in the “Summary Compensation Table” for the respective years. Average compensation for non-PEOs includes the following NEOs: (i) in 2025, Scott A. Crum, Alvise J. Munari, C.D. Baer Pettit and Andrew C. Wiechmann and (ii) in each of 2024, 2023, 2022 and 2021, Scott A. Crum, Robert J. Gutowski, C.D. Baer Pettit and Andrew C. Wiechmann.

(2)Compensation “actually paid” for the PEO and average compensation “actually paid” for our non-PEO NEOs in 2025, 2024, 2023, 2022 and 2021 reflects the respective amounts set forth in columns (c) and (e), adjusted as follows in the table below. However, the reconciliation of these amounts, as required under SEC rules, is presented only for 2025 in the table below. These dollar amounts do not reflect the actual amount of compensation earned by or paid to the PEO and our other NEOs during the applicable year. For information regarding the decisions made by our Compensation Committee with respect to the PEO’s and our other NEOs’ compensation for fiscal year 2025, see “Compensation Discussion and Analysis” beginning on page 58 of this Proxy Statement.

Fair values set forth in the table above are computed in accordance with ASC 718 as of the end of the respective fiscal year, other than fair values of awards that vest in the covered year, which are valued as of the applicable vesting date, or the fair values of awards forfeited in the covered year, which are valued as of the end of the prior fiscal year. The assumptions used for purposes of calculating fair values of awards as of the vest date or fiscal year-end date are the same as the assumptions used for purposes of calculating the grant date fair value of awards, except that, in the case of PSOs, the fair values at the time of grant were determined using the Black-Scholes option pricing model and the fair values as of the fiscal year-end date were determined using the Hull-White lattice model. The Hull-White lattice model requires consistent judgmental assumptions as the Black-Scholes pricing model, except that the expected life as a direct input for the Black-Scholes pricing model was estimated using the simplified method provided for by the SEC, while the expected life for the Hull-White lattice model was an implied output and estimated to be 5.2 years for the PSOs granted in 2023, 6.1 years for the PSOs granted in 2024, 6.9 years for the PSOs granted in 2025, and 7.6 years for the PPOs granted in 2025. In addition, for PSOs, the fair value is adjusted for any changes in the probability of achievement of the (i) a cumulative revenue performance goal and (ii) a cumulative adjusted EPS performance goal (each weighted equally under the terms of the PSOs).

Performance Measures

As described in more detail in the Compensation Discussion and Analysis beginning on page 58 of this Proxy Statement, our executive compensation program is designed to facilitate an “owner-operator” mindset amongst our senior executives. In connection with our pay-for-performance philosophy, we utilize multiple, complementary performance measures under our AIP and LTIP that measure and reward for performance against core financial, operational and strategic milestones that drive shareholder value creation.

Adjusted EPS, operating revenues and total net sales are utilized as performance measures for our AIP. Further information regarding these performance measures can be found under Compensation Discussion and Analysis.

Under our LTIP, we granted PSUs that are eligible to vest based on the achievement of an absolute TSR CAGR measured over a cumulative three-year performance period. We also granted PSOs that are eligible to vest based on the combined level of achievement of (i) a cumulative operating revenue performance goal and (ii) a cumulative adjusted EPS performance goal (each weighted equally) and measured over a cumulative three-year performance period.

The following table sets forth an unranked list of the “most important” performance measures we used to link pay with performance for 2025.


Performance Measures
Adjusted EPS
Operating Revenues
Total Net Sales(1)
3-Year Absolute TSR CAGR

(1)For purposes of the AIP, Total Net Sales reflects net new recurring subscription sales plus non-recurring sales weighted at 75%.

We do not consider any one of the above performance measures to be the single most important financial measure for our company or executive compensation design. However, adjusted EPS is a performance measure that is utilized under both our AIP and our LTIP and is a key metric used by our management and our investors in evaluating our performance, and therefore, for purposes of the 2025 Pay versus Performance Table, we disclose adjusted EPS to be the “most important” financial performance measure utilized in our executive compensation program for 2025 for linking pay with performance and as our “company-selected measure.”

Our Board of Directors recommends that you vote FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor.

PROPOSAL 3

Ratification of the Appointment of MSCI’s Independent Auditor

Proxies solicited by our Board will be voted FOR this ratification unless otherwise instructed.

The Audit Committee appointed PricewaterhouseCoopers LLP (“PwC”) as independent auditor for 2026 and presents this selection to the shareholders for ratification. PwC will audit our consolidated financial statements for the year ended December 31, 2026 and perform other permissible pre-approved services.

A PwC representative will attend the 2026 Annual Meeting to respond to your questions and will have the opportunity to make a statement if he or she desires to do so. If our shareholders fail to ratify the appointment of PwC, it will be regarded as notice to the Board and the Audit Committee to consider the selection of a different firm. Even if shareholders ratify the selection of PwC, the Audit Committee, in its discretion, may select a new independent auditor at any time during the year if it believes that the change would be in the best interest of the Company.

The Audit Committee periodically reviews the engagement of the independent auditor to assess, among other things, the skills, experience, service levels and costs associated with conducting the annual audit of the Company’s financial statements. PwC has served as our independent auditor since March 2014. The Audit Committee believes that the tenure of our independent auditor since March 2014 provides significant benefits, including deep institutional knowledge and expertise of our operations and business, enhanced audit quality, and efficiencies that contribute to the integrity and reliability of our financial reporting.

Vote Required and Recommendation

The affirmative vote of a majority of the votes cast at our 2026 Annual Meeting, at which a quorum is present, is required to approve Proposal No. 3. Abstentions shall not be treated as votes cast.

Pre-Approval Policy of the Audit and Risk Committee of Services Performed by Independent Auditors

The Audit Committee has implemented pre-approval policies and procedures related to the provision of audit and non-audit services by the independent auditor to ensure that the independent auditor maintains independence with respect to MSCI. Under these procedures, the Audit Committee annually pre-approves specified categories of audit, audit-related and other services to be provided by the independent auditor and the estimated fees related to those services. During the pre-approval process, the Audit Committee considers the impact of the types of services and the related fees on the independence of the auditor. Any single engagement with estimated fees in excess of $750,000 generally requires separate pre-approval by the full Audit Committee. Tax advisory services also require separate Audit Committee pre-approval. The Audit Committee has delegated authority to the Chair of the Audit Committee to pre-approve certain engagements not requiring approval by the full Audit Committee and the authority to approve increases to pre-approved fee limits within pre-approved service categories, subject to certain thresholds. Each Chair pre-approval must be documented in writing and reported to the full Audit Committee at its next scheduled meeting. The services and fees must be deemed compatible with the maintenance of the auditor’s independence, including compliance with SEC rules and regulations. Management reports to the Audit Committee the actual fees versus pre-approved amounts periodically throughout the year by category of service.

Audit Matters

Audit and Risk Committee Report

The Audit Committee operates under a written charter adopted by the Board, which is accessible through the “Corporate Governance” link under the “Investor Resources” tab found on our website’s Investor Relations homepage (https://ir.msci.com). The Audit Committee is responsible for the oversight of the integrity of the Company’s consolidated financial statements, the Company’s system of internal control over financial reporting, the Company’s risk management, the qualifications and independence of the Company’s independent auditor, the performance of the Company’s internal and independent auditors and the Company’s compliance with legal and regulatory requirements. The Audit Committee has the sole authority and responsibility to appoint, compensate, evaluate and, when appropriate, replace the Company’s independent auditor. The Board has determined that all of the Audit Committee’s members are independent under the applicable independence standards of the NYSE and the Exchange Act.

The Audit Committee serves in an oversight capacity and is not part of the Company’s managerial or operational decision-making process. Management is responsible for the financial reporting process, including the system of internal controls, for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States and for the report on the Company’s internal control over financial reporting. The Company’s independent auditor for the year ended December 31, 2025, PwC, was responsible for auditing the consolidated financial statements included in the Company’s 2025 Annual Report on Form 10-K, expressing an opinion as to their conformity with accounting principles generally accepted in the United States of America and expressing an opinion on the effectiveness of the Company’s internal control over financial reporting, as well as reviewing the Company’s interim condensed consolidated financial statements included in its Quarterly Reports on Form 10-Q. The Audit Committee’s responsibility is to oversee the financial reporting process and to review and discuss management’s report on the Company’s internal control over financial reporting. The Audit Committee relies, without independent verification, on the information provided to us and on the representations made by management, the internal auditor and the independent auditor.

The Audit Committee held ten meetings during the year ended December 31, 2025, and among other things:

•reviewed and discussed the Company’s quarterly and annual earnings releases;

•reviewed and discussed the (i) quarterly unaudited consolidated financial statements and related notes and (ii) audited consolidated financial statements and related notes to the consolidated financial statements for the year ended December 31, 2025 with management and PwC;

•reviewed and discussed the annual plan and scope of work of the independent auditor;

•reviewed and discussed the annual plan and scope of work of the internal auditor and summaries of significant reports to management by the internal auditor;

•met with PwC, the internal auditor and Company management in executive sessions to discuss the results of their examinations and evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting and compliance programs;

•reviewed and discussed the critical accounting policies set forth in the Company’s Annual Report on Form 10-K and reviewed critical audit matters reported by PwC;

•reviewed business and financial market conditions, including periodic assessments of risks posed to MSCI’s operations and financial condition (including those related to technology and cybersecurity);

•reviewed and discussed reports from MSCI’s Disclosure Committee; and

•evaluated the performance of PwC and approved their engagement as the Company’s independent auditor.

PwC also provided to the Audit Committee the written disclosures and the letters required by the applicable PCAOB requirements regarding PwC’s communications with the Audit Committee concerning independence, and represented that it is independent from the Company. We discussed with PwC their independence from the Company, and considered whether the services they provided to the Company beyond those rendered in connection with their integrated audit of the Company’s consolidated financial statements and internal control over financial reporting, and the reviews of the Company’s interim condensed consolidated financial statements included in its Quarterly Reports on Form 10-Q, were compatible with maintaining their independence.

Audit Matters

The Audit Committee is also responsible for reviewing and evaluating the senior members of the PwC team, particularly the lead audit partner and any other partners on the audit engagement teams, and ensuring required rotation of audit partners every five years, as required by SEC rules. One or more members of the Audit Committee also meet with candidates for the lead audit partner role, and the Audit Committee discusses the appointment before a rotation occurs.

During the year ended December 31, 2025, the Audit Committee also received regular updates on the amount of fees and scope of audit, audit-related and tax services provided. Pursuant to the pre-approval policies and procedures related to the provision of audit and non-audit services by the independent auditors as described above within “—Pre-Approval Policy of the Audit and Risk Committee of Services Performed by Independent Auditors,” the Audit Committee approved, among other things, fees related to the integrated audits, statutory audits, consultations and certain non-audit services. The Audit Committee also approved certain fees relating to tax services consisting of compliance and advisory services related to (i) tax consulting fees related to international and domestic tax matters, including international corporate restructurings, and (ii) tax compliance assistance.

Based on our review and these meetings, discussions and reports described above, and subject to the limitations on our role and responsibilities referred to above and in the Audit Committee’s charter, we recommended to the Board that the Company’s audited consolidated financial statements be included in the Company’s 2025 Annual Report on Form 10-K.

(3)Except as indicated in the footnotes to this table, to our knowledge each executive officer and director, as of February 27, 2026, had sole voting and investment power with respect to his or her shares of our common stock. Beneficial Ownership Totals may differ from those set forth in Statements of Changes in Beneficial Ownership reported on Form 4 filed with the SEC due to the exclusion herein of RSUs granted by the Company, as described in footnote (1) to this table.

(4)All executive officers and directors (other than Mr. Fernandez) each beneficially owned less than 1.0% of the shares of our outstanding common stock. Percentages for each beneficial owner are calculated in accordance with Rule 13d-3(d)(1) under the Exchange Act. Percentages for each NEO, executive officer and director as of February 27, 2026 and collectively as a group are calculated by dividing the number of shares beneficially owned by the sum of the number of our shares outstanding as of February 27, 2026 plus shares of our common stock that can be acquired through vesting of RSUs or through the exercise of stock options within 60 days of the date of this table (i.e., through April 28, 2026).

(5)Includes 335,069 shares of our common stock held by the Fernandez 2007 Children’s Trust of which the spouse of Mr. Fernandez is the trustee, 309,821 shares of our common stock held by the Henry Fernandez 2024 MSCI Annuity Trust of which Mr. Fernandez is the trustee, and 15,400 shares of our common stock held by each of Mr. Fernandez’s three children.

(8)Includes 22,290 shares of our common stock directly held by 1000396766 Ontario Inc., an entity over which Mr. Ashe retains sole investment and voting control. The common shares of 1000396766 Ontario Inc. are held by the Ashe (2022) Family Trust, a trust of which Mr. Ashe and his spouse are trustees and Mr. Ashe, his spouse and his children are beneficiaries.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company’s directors, executive officers and persons who beneficially own more than 10% of a registered class of the Company’s equity securities to file with the SEC reports on Forms 3, 4 and 5 concerning their ownership of, and transactions in, the common stock and other equity securities of the Company. As a practical matter, the Company assists its directors and executives by monitoring transactions and completing and filing reports on their behalf.

Based solely on the Company’s review of copies of such reports filed with the SEC and written representations that no other reports are required, the Company believes that all of its executive officers, directors and those greater-than-10% shareholders that filed any reports for the year ended December 31, 2025 reported all transactions on a timely basis, with the exception of a late Form 3 filed for Mr. Alvise J. Munari on December 18, 2025.

Other Matters

Transactions with Directors and Related Entities

During 2025, in the ordinary course of business, The Rockefeller University subscribed to, licensed or purchased certain MSCI products and services. The Company recognized approximately $0.3 million in revenue from these transactions. Paula Volent, one of our directors, has served as Vice President and Chief Investment Officer of The Rockefeller University since August 2021.

Related Person Transactions Policy

The Board recognizes that related party transactions can present a heightened risk of potential or actual conflicts of interest and may create the appearance that Company decisions are based on considerations other than the best interests of the Company and its shareholders. Accordingly, the Company maintains a written Related Person Transactions Policy (the “Policy”), which governs the approval of related person transactions to ensure that they are fair and in the best interests of the Company. The Governance Committee administers the Policy. It is the responsibility of each director, director nominee and executive officer to promptly notify the legal department of transactions in which he or she may be involved. The legal department also conducts diligence and maintains controls and procedures to identify and submit for review and approval any such transactions.

Under the Policy, the legal department determines whether the proposed transaction constitutes a related person transaction requiring review under the Policy and/or disclosure. If the legal department determines that (i) the proposed transaction constitutes a related person transaction or (ii) it would be beneficial to further review the transaction under the Policy, then the legal department may review and approve certain transactions pursuant to delegation from the Governance Committee or refer the transactions to the Governance Committee. No director may participate in any discussion or approval of a transaction for which he or she or a member of his or her immediate family is a related person.

When evaluating a proposed Related Person Transaction, the legal department or the Governance Committee, as applicable, will consider all relevant facts and circumstances, including: (1) the dollar amount of the transaction, the commercial reasonableness of the terms and the purpose of the transaction, as well as the benefit to the Company; (2) the nature of the negotiations, including (i) whether negotiations were at arm’s length and the result of fair dealing and (ii) whether the related person was involved in the negotiations; (3) the terms and conditions of comparable or similar transactions; (4) whether the transaction is provided on terms that may be more favorable than those available to others; (5) the materiality and character of the related person’s interest in the transaction and whether there may be any conflicts of interest; (6) whether the transaction would be considered unusual for one or both of the parties and (7) whether the transaction may impact director independence if applicable. Related person transactions will not be approved if the legal department or the Governance Committee, as applicable, determines the transaction to be inconsistent with the interests of the Company and its shareholders.

Other Business

We do not know of any matters that may be presented for action at the meeting other than those described in this Proxy Statement. If any other matter is properly brought before the meeting, the proxy holders will vote on such matter in their discretion.

114

Annex A: Frequently Asked Questions

Who may attend the 2026 Annual Meeting?

All shareholders as of February 27, 2026, or their duly appointed proxies, may attend the 2026 Annual Meeting. In order to attend the 2026 Annual Meeting, a shareholder must own MSCI common stock at the close of business on February 27, 2026. If your shares are held in the name of a broker, bank, custodian, nominee or other record holder (“street name”), you must obtain a proxy, executed in your favor, from the holder of record (that is, your broker, bank, custodian, or nominee) to be able to vote at the 2026 Annual Meeting.

Who may vote at the 2026 Annual Meeting?

You can vote your shares of MSCI common stock at our 2026 Annual Meeting if you were a shareholder at the close of business on February 27, 2026 (the “record date”). As of February 27, 2026, there were 73,120,206 shares of MSCI common stock outstanding. Each share of MSCI common stock entitles you to one vote on each matter voted on at the annual meeting of shareholders.

A majority of the shares of MSCI common stock outstanding at the close of business on the record date must be present in order to hold the meeting and conduct business. This is called a “quorum.” Your shares are counted as present at the 2026 Annual Meeting if you vote through the internet at the virtual annual meeting of shareholders or properly submit your proxy prior to the 2026 Annual Meeting.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of printed proxy materials?

Pursuant to the “notice and access” rules adopted by the SEC, we are making this Proxy Statement and our 2025 Annual Report on Form 10-K (including any amendments thereto) available to our shareholders over the internet. As a result, unless you have previously requested electronic access to our proxy materials or the receipt of paper proxy materials, you will receive a Notice of Internet Availability of Proxy Materials containing instructions on how to access this Proxy Statement and our 2025 Annual Report on Form 10-K (including any amendments thereto) over the internet, how to request a free paper copy of these materials and how to vote via the internet. We will mail the Notice of Internet Availability of Proxy Materials on or about March 11, 2026. The Notice of Internet Availability of Proxy Materials is not a proxy card and cannot be used to vote your shares.

In addition, if you are voting online, you will be prompted to consent to receiving proxy materials electronically in future years. Choosing to receive your future proxy materials electronically will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings of shareholders on the environment. If you choose to receive future proxy materials electronically, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials electronically will remain in effect until you terminate it. See “How do I sign up for electronic delivery of proxy materials?” below for further information on electing to receive proxy materials electronically.

What is the difference between holding shares as a “record holder” and as a beneficial owner of shares held in “street name”?

Record Holder. If your shares are registered directly in your name with MSCI’s transfer agent, Broadridge Corporate Issuer Solutions, Inc. (including its affiliates, “Broadridge”), you are considered a “record holder” with respect to those shares, and the Notice of Internet Availability of Proxy Materials will be sent directly to you.

Beneficial Owner of Shares Held in “Street Name.” If your shares are held in an account with a brokerage firm, bank, broker dealer, or other intermediary, then you are considered a beneficial owner of shares held in “street name,” and the Notice of Internet Availability of Proxy Materials and other proxy materials will be forwarded to you by that intermediary. As a beneficial owner of shares held in “street name,” you have the right to direct that intermediary on how to vote the shares held in your account by following their instructions for voting and using their forms. If you do not provide your brokerage firm, bank, broker dealer or other intermediary with instructions on how to vote your shares, such intermediary or intermediary nominee will be able to vote your shares only with respect to the proposal related to the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2026.

116

Annex A: Frequently Asked Questions

How will my shares be voted if I do not give specific voting instructions and what are broker non-votes?

Record Holders. If you indicate that you wish to vote as recommended by our Board or if you sign, date and return a proxy card but do not give specific voting instructions, then the proxy holders will vote your shares in the manner recommended by our Board on all matters presented in this Proxy Statement (e.g., “FOR” for Proposal No. 1, No. 2 and No. 3) and in their discretion regarding any other matters properly presented for a vote at our 2026 Annual Meeting. As of the date of this Proxy Statement, we did not know of any proposals or matters to be raised at the 2026 Annual Meeting other than those presented in this Proxy Statement.

Beneficial Owners of Shares Held in “Street Name.” Broker non-votes occur when your brokerage firm, bank, broker dealer or other intermediary has not received specific voting instructions from you with respect to shares held in “street name” and the broker does not have discretionary voting authority with respect to a proposal. If you are the beneficial owner of shares held in “street name” and you do not give instructions as to how to vote, your broker may have authority to vote your shares only on discretionary items but not on non-discretionary items, as determined by the NYSE.

•Non-discretionary items. The following proposals are considered “non-discretionary” items: Proposal No. 1—election of directors and Proposal No. 2—approve, by non-binding vote, our executive compensation.

•Discretionary item. Proposal No. 3—the ratification of the appointment of PricewaterhouseCoopers LLP as the Company’s independent auditor for 2026 is a “discretionary” item. NYSE member brokers that do not receive voting instructions from beneficial owners of shares held in “street name” may vote on this proposal in their discretion, subject to any voting policies adopted by the broker holding your shares.

Broker non-votes are counted as present for purposes of determining the presence or absence of a quorum for the transaction of business. However, broker non-votes are not counted for purposes of Proposal Nos. 1, 2 and 3 and will therefore have no effect on the outcome of these proposals. Therefore, if you hold your shares in an account with a brokerage firm, bank, a broker dealer or other intermediary, it is critically important that you submit your voting instructions if you want your shares to count for the non-discretionary items listed above.

How are abstentions treated?

Abstentions are also counted as present for purposes of determining the presence or absence of a quorum for the transaction of business. Abstentions have no effect on the determination of whether a nominee or any of the proposals have received the vote of a majority of all votes cast.

What are my choices for casting my vote on each matter to be voted on?


Proposal No.	Proposal	Voting Options	Effect of Abstentions
1	Election of Directors	FOR, AGAINST or ABSTAIN (for each director nominee)	No effect—not counted as a “vote cast”
2	Advisory Vote to Approve Executive Compensation (Say-on-Pay)	FOR, AGAINST or ABSTAIN	No effect—not counted as a “vote cast”
3	Ratification of the Appointment of MSCI’s Independent Auditor	FOR, AGAINST or ABSTAIN	No effect—not counted as a “vote cast”

How many votes are required to elect directors and adopt proposals?

The election of each director and the ratification of the appointment of PwC as MSCI’s independent auditor require the affirmative vote of a majority of all votes cast. For purposes of the election of directors, a majority of votes cast shall mean that the number of votes cast “for” a director’s election exceeds the number of votes cast “against” the director’s election. The approval of a resolution regarding the compensation of our NEOs as disclosed in this Proxy Statement is a non-binding advisory vote; however, we value the opinions of our shareholders and will take into account the outcome of this vote in considering future compensation arrangements. A majority of the shares entitled to vote on a matter, whether present virtually or by proxy, will constitute a quorum at the meeting.


			2026 PROXY STATEMENT			117

Annex A: Frequently Asked Questions

What happens if a director does not receive a majority of the votes required for his or her re-election?

Under the laws of Delaware (our state of incorporation), if the director is not elected at the annual meeting, the director will continue to serve on the Board as a “holdover director.” However, our Bylaws provide that, in order for an incumbent director to become a nominee of the Board, the director must submit an irrevocable resignation as director that becomes effective if (i) he or she does not receive a majority of the votes cast in an uncontested election and (ii) the Board accepts the resignation. If a director does not receive a majority of the votes cast in an uncontested election, the Governance Committee will consider the director’s resignation and recommend to the Board whether to accept or reject the resignation. The Board will decide whether to accept or reject the resignation and publicly disclose its decision within 90 days after the election results are certified.

How do I revoke or change my proxy?

If you are a “record holder,” you can revoke or change your proxy at any time before your shares are voted, subject to the voting deadlines that are described on the proxy card or voting instruction form, as applicable, by:

•Voting again by internet or by telephone (only your last internet or telephone proxy submitted prior to the meeting will be counted);

•Signing and returning a new proxy card with a later date; or

•Voting by internet while attending the virtual annual meeting (attending the annual meeting by internet does not revoke your proxy unless you vote by internet during the virtual annual meeting).

If you are a “record holder,” you may also revoke your proxy by giving written notice of revocation to c/o Corporate Secretary, MSCI Inc., 7 World Trade Center, 250 Greenwich Street, 49th Floor, New York, New York 10007, which must be received no later than 5:00 P.M. Eastern Time, on April 20, 2026.

If you are a beneficial owner of shares held in “street name,” you may revoke your proxy by following the instructions your brokerage firm, bank, broker dealer or other intermediary provides.

Will my vote be confidential?

Our Bylaws provide that your individual vote is confidential and will not be disclosed to any officer, director or employee of MSCI, except as required by law and in certain limited circumstances such as when you request or consent to disclosure, or make a request or comment on the proxy card.

Who counts the votes cast at the 2026 Annual Meeting?

Representatives of Broadridge will tabulate the votes cast at the 2026 Annual Meeting, and American Election Services, LLC will act as the independent inspector of elections.

Where can I find the voting results of the 2026 Annual Meeting?

We expect to announce the preliminary voting results at the 2026 Annual Meeting. The final voting results will be tallied by representatives of Broadridge, our inspector of elections, and will be subsequently published by us by the filing of a Current Report on Form 8-K with the SEC within four business days after the 2026 Annual Meeting.

Who will pay for the cost of the proxy solicitation?

We pay the expenses of the preparation of proxy materials and the solicitation of proxies for our 2026 Annual Meeting. Proxies may be solicited on our behalf by directors, officers, employees or agents in person or by telephone, electronic transmission and facsimile transmission. Our directors, officers and employees will receive no additional compensation for any such solicitation.

We have also hired D.F. King & Co., Inc. (“D.F. King”), 28 Liberty Street, 53rd Floor, New York, NY 10005, to assist in the distribution and solicitation of proxies. We will pay D.F. King a fee of $21,000, plus reasonable expenses, for these services. We will reimburse brokers and other similar institutions for costs incurred by them in mailing proxy materials to beneficial owners.

In addition, the shareholder must confirm his or her candidate’s consent to serve as a director.

Shareholders must send recommendations to the Governance and Corporate Responsibility Committee, c/o Corporate Secretary, MSCI Inc., 7 World Trade Center, 250 Greenwich Street, 49th Floor, New York, New York 10007.

If we hold our 2027 annual meeting of shareholders more than 30 days before or after April 21, 2027 (the one-year anniversary date of the 2026 Annual Meeting), we will disclose the new deadline by which shareholder proposals must be received under Item 5 of Part II of our earliest possible Quarterly Report on Form 10-Q or, if impracticable, by any means reasonably determined to inform shareholders. In addition, shareholder proposals must otherwise comply with the requirements of Rule 14a-8 under the Exchange Act and with the SEC regulations under Rule 14a-8 regarding the inclusion of shareholder proposals in company-sponsored proxy materials.

(2)This adjustment reflects discrete income tax expense recognized in connection with a multi-phase internal legal entity restructuring that commenced in Q4 2025 and was completed on January 4, 2026. In Q4 2025, the Company recognized discrete tax expense of $38 million related to the first phase, and expects to recognize a discrete tax benefit of approximately $88 million in 2026 related to the subsequent phases of this internal legal entity restructuring. Management excludes these discrete tax effects from non-GAAP results because they are not indicative of ongoing operating performance or the Company’s underlying tax profile. Amounts relating to 2026 tax impacts are preliminary and subject to adjustment pending finalization of tax calculations related to the restructuring.

(3)The pre-tax gain from changes in ownership interest of Burgiss of $143.0 million is non-taxable; however, $8.6 million of income tax expense recognized during the year ended December 31, 2023 was related to the remeasurement of the deferred tax liability on the Company’s previous equity method investment in Burgiss.

(4)Adjustments relate to the tax effect of non-GAAP adjustments, other than the tax impact of internal legal entity restructuring which is reflected above, which were determined based on the nature of the underlying non-GAAP adjustments and their relevant jurisdictional tax rates.

Notes Regarding the Use of Non-GAAP Financial Measures

MSCI has presented supplemental non-GAAP financial measures as part of this Proxy Statement. A reconciliation is provided that reconciles each non-GAAP financial measure with the most comparable GAAP measure. The non-GAAP financial measures presented in this Proxy Statement should not be considered as alternative measures for the most directly comparable GAAP financial measures. The non-GAAP financial measures presented in this Proxy Statement are used by management to monitor the financial performance of the business, inform business decision-making and forecast future results.

“Adjusted EBITDA” is defined as net income before (1) provision for income taxes, (2) other expense (income), net, (3) depreciation and amortization of property, equipment and leasehold improvements, (4) amortization of intangible assets and, at times, (5) certain other transactions or adjustments, including, when applicable, impairment related to sublease of leased property and certain acquisition-related integration and transaction costs.

“Adjusted net income” and “adjusted EPS” are defined as net income and diluted EPS, respectively, before the after-tax impact of: the amortization of acquired intangible assets and, at times, certain other transactions or adjustments, including, when applicable, the impact related to certain acquisition-related integration and transaction costs, the impact related to the write-off of deferred fees on debt extinguishment, the impact related to certain gains or losses on investees, and the impact of certain discrete tax items.

Asset-based fees adjusted for the impact of foreign currency exchange rate fluctuations does not adjust for the impact from foreign currency exchange rate fluctuations on the underlying assets under management.

We believe adjusted EBITDA is a meaningful measure of the operating performance of MSCI because it adjusts for significant one-time, unusual or non-recurring items as well as eliminates the accounting effects of certain capital spending and acquisitions that do not directly affect what management considers to be our ongoing operating performance in the period.

We believe adjusted net income and adjusted EPS are meaningful measures of the performance of MSCI because they adjust for the after-tax impact of significant one-time, unusual or non-recurring items as well as eliminate the impact of any transactions that do not directly affect what management considers to be our ongoing operating performance in the period. We also exclude the after-tax impact of the amortization of acquired intangible assets and amortization of the basis difference between the cost of the equity method investment and MSCI’s share of the net assets of the investee at historical carrying value, as these non-cash amounts are significantly impacted by the timing and size of each acquisition and therefore not meaningful to the ongoing operating performance in the period.

We believe that the non-GAAP financial measures presented in this Proxy Statement facilitate meaningful period-to-period comparisons and provide a baseline for the evaluation of future results.


			2026 PROXY STATEMENT			123

Annex B: Supplemental Financial Information

Adjusted EBITDA, adjusted net income, adjusted EPS and Capex are not defined in the same manner by all companies and may not be comparable to similarly-titled non-GAAP financial measures of other companies. These measures can differ significantly from company to company depending on, among other things, long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. Accordingly, the Company’s computation of these measures may not be comparable to similarly-titled measures computed by other companies.

Supplemental Information Regarding Run Rate and other Metrics

Run Rate is a key operating metric and is important because an increase or decrease in our Run Rate ultimately impacts our operating revenues over time. At the end of any period, we generally have subscription and investment product license agreements in place for a large portion of total revenues for the following 12 months. We measure the fees related to these agreements and refer to this as “Run Rate.”

Run Rate estimates, at a specific point in time, the annualized value of the recurring portion of executed client contracts (“Client Contracts”) expected to generate revenues over the next 12 months, assuming that all such Client Contracts are renewed and using fixed foreign exchange rates. Run Rate includes new Client Contracts upon execution, even if the license start date and related revenue recognition occur later.

For Client Contracts where fees are linked to an investment product’s assets or trading volume or fees (referred to as “Asset-based Fees”), the Run Rate calculation is based on:

•For exchange-traded funds (“ETFs”): assets under management as of the last trading day of the period;

•For non-ETF products: the most recent client-reported assets under management; and

•For listed futures and options contracts: the most recent quarterly volumes and/or reported exchange fees.

Run Rate excludes fees associated with one-time or other non-recurring transactions.

We remove from Run Rate the annualized fee value associated with products or services under any Client Contracts when (i) we have received a notice of termination, reduction in fees, non-renewal or other clear indication that the client does not intend to continue its subscription at then current fees; and (ii) management has determined that such notice or indication reflects the client’s final decision to terminate, not renew or renew at a lower fee the applicable products or services, even if such termination or non-renewal is not yet effective (each such event, a “Subscription Cancellation”).

In general, when a client reduces the fees paid to MSCI associated with a reduction in the number of products or services to which it subscribes within a segment, or a switch between products or services within a segment, unless the client switches to a product or service that management considers a replacement, such reduction or switch is treated as a Subscription Cancellation. In the cases where the client switches products or services to a replacement service, only the net decrease, if any, is reported as a cancellation.

•In the Analytics and Sustainability and Climate operating segments, substantially all such product or service switches are treated as replacements and are netted accordingly.

•In contrast, in the Index, Real Assets, and Private Capital Solutions operating segments, such netting treatment is applied only in limited circumstances.

Non-recurring sales represent the aggregate value of client agreements entered into during the period that generate non-recurring fees and are not included in Run Rate, even if such agreements span multiple periods or years.

Net new recurring subscription sales (also referred to as recurring net new sales) represent new recurring subscription sales minus the impact of subscription cancellations, capturing the net impact to Run Rate for the period.

For purposes of the AIP, Total Net Sales reflects net new recurring subscription sales plus non-recurring sales weighted at 75%.
