Majority Vote Standard
The Company has adopted a majority vote standard for the election of directors which provides that a nominee must receive more FOR votes than AGAINST votes for election as a director. Should a nominee fail to achieve this threshold, the nominee is expected to tender his or her resignation to the Board. The Governance/Nominating Committee (the “Governance Committee”) will consider the resignation letter and recommend to the Board the action to be taken with respect to the offered resignation, and the Board, in its discretion, will consider and act on the Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results.
Compensation of Directors
The Compensation Committee, in consultation with the Governance Committee, reviews all forms of independent director compensation on an annual basis and approves changes, when appropriate. The Compensation and Governance Committees are supported in this review by Exequity, LLP, the Compensation Committee’s independent compensation consultant. The review examines director compensation in relation to two comparator groups: the Peer Group and General Industry Group. The Peer Group includes the same companies used to benchmark executive pay (as discussed in further detail on page 26). The General Industry Group includes 100 companies; 50 companies larger and 50 companies smaller than Gartner, with median revenues similar to that of Gartner. The Peer Group serves as the primary comparison with the General Industry Group serving as an additional reference, recognizing the broader labor market for director talent. Regular review of the director compensation program is intended to help ensure that the director compensation is reasonable and reflects a mainstream approach to the structure of the compensation components and

the method of delivery. In October 2023, the Compensation Committee conducted a review of director compensation and determined no changes to director pay were necessary for 2024 at that time. In connection with our transition to a combined chairman and CEO role, in June 2024, the Compensation Committee added an additional retainer fee of $50,000 for the Lead Independent Director. No other changes were made to the director compensation program.
Directors who are also employees receive no additional compensation for their services as directors. Non-management directors are reimbursed for their meeting attendance expenses and receive the following compensation for their service as directors. The table below sets forth director compensation for 2024:

Annual Director Retainer Fee: | $90,000 per director, an additional $50,000 for our lead independent director, and an additional $150,000 for a non-executive Chairman of the Board, payable in arrears in four equal quarterly installments, on the first business day of each calendar quarter. These amounts are paid in fully vested common stock equivalents (“CSEs”) granted under the Company’s Long-Term Incentive Plan (the “LTIP”), except that a director may elect to receive up to 50% of this fee in cash. The CSEs convert into Common Stock on the date the director’s continuous status as a director terminates, unless the director elects accelerated release as provided in the LTIP. The number of CSEs awarded is determined by dividing the aggregate director fees owed for a quarter (other than any amount payable in cash) by the closing price of the Common Stock on the first business day following the close of that quarter.
Annual Committee Chair Fee: | $10,000 for the chair of our Governance Committee and $15,000 for the chairs of our Audit and Compensation Committees. Amounts are payable in the same manner as the Annual Director Retainer Fee.
Annual Committee Member Fee: | $7,500 for our Governance Committee members, $10,000 for our Compensation Committee members and $15,000 for our Audit Committee members. Committee chairs receive both a committee chair fee and a committee member fee. Amounts are payable in the same manner as the Annual Director Retainer Fee.
Annual Equity Grant: | $240,000 in value of restricted stock units (“RSUs”), awarded annually on the date of the Annual Meeting. The number of RSUs awarded is determined by dividing $240,000 by the closing price of the Common Stock on the grant date. The RSUs vest one year after grant subject to continued service as director through that date; release may be deferred beyond the vesting date at the director’s election in accordance with the LTIP.

In addition, our non-employee directors may participate in the Gartner Charity Match Program. Under this program, contributions to eligible non-profit organizations are matched by Gartner, up to a maximum of $20,000 per director per calendar year.
Director Compensation Table
This table sets forth compensation of our non-management directors on account of services rendered as a director in 2024. Mr. Hall receives no additional compensation for service as director or Chairman of the Board. Ms. Dykstra was appointed Lead Independent Director on July 1, 2024. Contemporaneously, she stepped down from the Audit Committee and was appointed to the Governance Committee. Mr. Smith stepped down as Chairman of the Board and was appointed to the Governance Committee on July 1, 2024 and resigned from the Board, the Audit and the Governance Committees on December 2, 2024. Their compensation for these roles was prorated accordingly.

(4)Any aggregate sum discrepancies are due to rounding.
(5)Mr. Smith retired from the Board on December 2, 2024.
Director Stock Ownership and Holding Period Guidelines
The Board believes directors should have a financial interest in the Company. Accordingly, each director is required to hold shares of Gartner common stock with a value of not less than five times the Annual Director Retainer Fee. Directors are required to achieve the guideline within three years of joining the Board. In the event a director has not satisfied the guideline within such three-year period, he/she will be required to hold 50% of net after-tax shares received from the Company either in the form of equity awards or released CSEs until the guideline is achieved. We permit directors to apply deferred and unvested equity awards towards satisfying these requirements. All our directors as of December 31, 2024 were in compliance with these guidelines on that date.

Board Principles and Practices
Our Board Principles and Practices are reviewed annually and revised in light of legal, regulatory or other developments, as well as emerging best practices, by our Governance Committee and Board. The Board Principles and Practices, which are posted on https://investor.gartner.com, describe the Board’s responsibilities, its role in strategic development and other matters, discussed below.
Director Independence
Our Board Principles and Practices require that our Board be comprised of a majority of directors who meet the criteria for independence from management set forth by the New York Stock Exchange (the “NYSE”) in its corporate governance listing standards.
Our committee charters likewise require that our standing Audit, Compensation and Governance Committees be comprised only of independent directors. Additionally, the Audit Committee members must be independent under Section 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Compensation Committee members must be independent under Rule 16b-3 promulgated under the Exchange Act as well as applicable NYSE corporate governance listing standards.
Utilizing all of these criteria, as well as all relevant facts and circumstances, the Board annually assesses the independence from management of all non-management directors and committee members by reviewing the commercial, financial, familial, employment and other relationships between each director and the Company, its auditors and other companies that do business with Gartner. Because of our worldwide reach, it is not unusual for Gartner to engage in ordinary course of business transactions involving the sale of research or consulting services with entities affiliated with one of our directors, or their immediate family members. The Board considered these transactions in determining director independence and determined that such transactions did not impair any director’s independence.
After analysis and recommendation by the Governance Committee, the Board determined that:
•all non-management directors who served during the 2024 fiscal year (Peter Bisson, Richard Bressler, Raul Cesan, Karen Dykstra, Diana Ferguson, Anne Sutherland Fuchs, William Grabe, José Gutiérrez, Stephen Pagliuca, Eileen Serra and James Smith), are independent under the NYSE listing standards;
•our Audit Committee members (Messrs. Bressler, Bisson and Gutiérrez) are independent under the criteria set forth in Section 10A-3 of the Exchange Act; and

2025 Proxy Statement | 10

Corporate Governance

•our Compensation Committee members (Mr. Cesan and Mses. Fuchs and Serra) are independent under the criteria set forth in Exchange Act Rule 16b-3 as well as under applicable NYSE corporate governance listing standards.
Board Leadership Structure
Our Board Principles and Practices provide that the Board annually reviews its leadership structure and selects a Chairman of the Board. Maintaining this flexibility allows the Board to determine whether to separate or combine the CEO and the Chairman based upon the Company’s needs and circumstances from time to time. The Board maintains the ability to change its leadership structure at any time at its election. In July 2024, the Board combined the roles of the CEO and Chairman. The Board believes that the present structure, which includes a Lead Independent Director with well-defined responsibilities, provides the Company and the Board with strong leadership, critical institutional knowledge and appropriate independent oversight that serve the best interests of our stockholders.
Mr. Hall, who serves as our CEO and Chairman, has had many successful years leading Gartner as its CEO, providing him with a deep understanding of the Company's operations, strategic direction, and industry landscape. This company insight is crucial for aligning the Board's oversight with the Company's long-term goals and ensuring informed decision-making. The Board believes that Mr. Hall’s experience leading and growing the Company through various market conditions and his extensive institutional knowledge put him in the best position to provide broad leadership for the Board. Additionally, the Board believes that having Mr. Hall as the CEO and Chairman allows Gartner to convey its short-term and long-term strategy with a single voice to stockholders, customers, and other stakeholders.
Our Board Principles and Practices require if the Chairman of the Board is not independent, the independent directors appoint a Lead Independent Director. The Board believes that a Lead Independent Director strengthens the effectiveness of the independent directors, improves risk oversight, and provides a conduit for independent directors to openly present issues or concerns to the Board. Ms. Dykstra, our Lead Independent Director, has complex, global technology business leadership experience, public company expertise, and an extensive background in finance that the Board believes amplifies her role as Lead Independent Director.
In connection with designating Ms. Dykstra as the Lead Independent Director, the Board amended the Board Principles and Practices to provide additional clearly defined responsibilities for the Lead Independent Director to further strengthen the Board’s independent oversight, including:
•Being contactable directly by stockholders (see Stockholder Communications on page 58);
•Working with the Chairman and CEO, management and committee chairs to ensure meeting agendas cover appropriate topics and that schedules for Board and committee meetings permit sufficient time for discussion of all agenda items;
•Presiding over separate executive sessions of the independent directors following the executive sessions presided over by the Chairman;
•Preparing annual feedback to the CEO based on input from other directors; acting as the Board’s designee to negotiate any amendment or renewal of the CEO’s employment agreement (subject to the approval of the Compensation Committee or Board, as applicable);
•Calling special meetings of the Board as needed; and
•Chairing executive sessions and meetings of the Board or other Board responsibilities in the absence of the Chairman.
Risk Oversight
The Board of Directors is responsible for ensuring that an appropriate culture of risk management exists within Gartner. Our Board, together with management, oversees risk at Gartner. The Board exercises its oversight both directly and through its committees. Each committee keeps the Board informed of its oversight efforts through regular reporting to the full Board by the committee chairpersons. The Company’s strategic direction proposed by management is reviewed and approved annually and more frequently as necessary by the Board.

2025 Proxy Statement | 11

Corporate Governance

The Audit Committee provides general oversight of the performance of the Company’s internal audit function. The Audit Committee reviews the results of the internal audit annual risk assessment and the proposed internal audit plan. The Company’s internal audit function provides quarterly reports to the committee, including updates on ongoing internal audit activities, results of audits and any changes to the audit plan. Internal audit also meets with the Audit Committee in executive session on a quarterly basis.
The Chief Legal Officer, who serves as Chief Compliance Officer, also provides reports to the Audit Committee on a quarterly basis concerning the effectiveness and status of the Company’s legal and ethical compliance program and initiatives, helpline activities and litigation matters.
The Company maintains internal controls and procedures over financial reporting, as well as enterprise wide internal controls, which are updated and tested annually by management and our independent registered public accounting firm. Our independent registered public accounting firm also attends Audit Committee meetings, and the Audit Committee meets with them in executive session quarterly.
Data Privacy and Cybersecurity Risk Oversight
The Audit Committee has the primary responsibility of assisting our Board of Directors in overseeing risk related to cybersecurity matters. The Board and/or the Audit Committee receive quarterly cybersecurity-related reports from our Chief Information Officer (“CIO”), which may address a wide range of topics, such as: cybersecurity strategy, the threat environment, the status of ongoing information security program initiatives, and information security program metrics. Additionally, we have documented protocols by which certain cybersecurity incidents that meet established reporting thresholds are escalated within the Company and, where appropriate, reported to the Board and/or the Audit Committee.
Human Capital Management Oversight
The Compensation Committee oversees human capital management. The Compensation Committee reviews the Company’s strategies, initiatives and programs related to human capital management, including with respect to matters such as talent recruitment, development and retention, workplace environment and culture, and inclusion.
Corporate Responsibility Oversight
The Governance Committee is responsible for overseeing and periodically reviewing the Company’s corporate responsibility priorities and initiatives, taking into consideration the impact on internal and external stakeholders. The Governance Committee and/or Board receives quarterly updates on Gartner’s approach and progress on corporate responsibility matters. The Company’s Corporate Responsibility Executive Council, consisting of the CFO, Chief Human Resources Officer, Chief Legal Officer, CIO, Head of Conferences and other selected leaders, meets on a quarterly basis to discuss corporate responsibility-related topics. Additionally, the Environmental Sustainability Steering Committee, consisting of leaders from Conferences, Corporate Communications, Corporate Social Responsibility, Finance, HR, IT, Legal, Real Estate, Source to Contract (procurement), and Research and Advisory teams, creates advances and oversees the environmental sustainability strategy at Gartner.
Risk Assessment of Compensation Policies and Practices
Management conducts an annual risk assessment of the Company’s compensation policies and practices, including all executive, non-executive and business unit compensation policies and practices, as well as the variable compensation policies applicable to our global sales force. The results of this assessment are reported to the Compensation Committee. For 2024, management concluded, and the Compensation Committee agreed, that no Company compensation policies and practices created risks that were reasonably likely to have a material adverse effect on the Company.
Management Succession Planning
Succession planning is one of the Board’s most critical functions — to develop leaders who will successfully build the Company’s business. The Board and the Governance Committee regularly review and discuss management development and succession plans for the Chief Executive Officer and his direct reports to support the Company’s long-term growth. This review includes an assessment of senior executives and their potential as successor to the Chief Executive Officer or his direct reports.

Board and Committee Meetings and Annual Meeting Attendance
Our Board held four meetings in 2024. During 2024, all our directors attended at least 75% of the Board and committee meetings held during the periods in which such director served as a director and/or committee member. At each regular quarterly Board and committee meeting, time is set aside for the non-management directors to meet in executive session without management present. Ms. Karen E. Dykstra, Lead Independent Director of the Board, presides over these executive sessions at the Board meetings, and each committee chairperson presides over the executive sessions at their respective committee meetings. Directors are not required, but are invited, to attend the Annual Meeting of Stockholders. In 2024, Mr. Hall and other executive officers of the Company attended the 2024 Annual Meeting of Stockholders.
Committees Generally and Charters
As noted above, our Board has three standing committees: Audit, Compensation and Governance/Nominating, and all committee members have been determined by our Board to be independent under applicable standards. Our Board has approved a written charter for each standing committee, which is reviewed annually and revised as appropriate. The table below provides information for each Board Committee:

Mr. James Smith served on the Audit Committee and Governance Committee prior to his retirement on December 2, 2024.

Audit Committee

Our Audit Committee serves as an independent body to assist in Board oversight of:
✓ | the integrity of the Company’s financial statements;
✓ | the Company’s compliance with legal and regulatory requirements;
✓ | the independent registered public accounting firm’s retention, qualifications and independence; and
✓ | the Company’s Risk (including internal controls and cybersecurity risks), Compliance and Internal Audit functions.

Gartner has a separately designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Our Board has determined that Messrs. Bressler and Gutiérrez qualify as audit committee financial experts, as defined by the rules of the Securities and Exchange Commission (the “SEC”), and that all members have the requisite accounting or related financial management expertise and are financially literate as required by the NYSE corporate governance listing standards.
Additionally, the Audit Committee is directly responsible for the appointment, compensation and oversight of our independent registered public accounting firm, KPMG; approves the engagement letter describing the scope of the annual audit; approves fees for audit and non-audit services; provides an open avenue of communication among the independent registered public accounting firm, the risk and internal audit functions, management and the Board; resolves disagreements, if any, between management and the independent registered public accounting firm regarding financial reporting for the purpose of issuing an audit report in connection with our financial statements and our internal control over financial reporting; and prepares the Audit Committee Report required by the SEC and included in this Proxy Statement on page 50 below.
The independent registered public accounting firm reports directly to the Audit Committee. By meeting with the independent registered public accounting firm, the internal auditor, and operating and financial management personnel, the Audit Committee oversees matters relating to accounting standards, policies and practices, any changes thereto and the effects of any changes on our financial statements, financial reporting practices and the quality and adequacy of internal controls. Additionally, the Audit Committee provides general oversight of the performance of the Company’s internal audit function. After each Audit Committee meeting, the Committee meets separately with the CFO, the Chief Compliance Officer, the internal auditor and the independent registered public accounting firm without management present.
The Audit Committee has established procedures for (i) the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and/or securities law matters, and (ii) the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters or securities law matters. A toll-free phone number and web-submission form, in local language, managed by a third party is available for confidential and anonymous submission of concerns relating to accounting, auditing and illegal or unethical matters, as well as alleged violations of law, Gartner’s Code of Conduct or any other policies. All submissions to the helpline are reported to the Chief Compliance Officer (or designee) and the internal auditor. At each regular meeting, the Chief Legal Officer, as the Company’s Chief Compliance Officer, and his designees provide quarterly reports to the Audit Committee on helpline submissions and other ethics and compliance matters. The Audit Committee has the power and funding to retain independent counsel and other advisors as it deems necessary to carry out its duties.

The Governance Committee is responsible for assessing the effectiveness of the Board by reviewing its size and composition. The Board evaluates its performance, effectiveness, composition, and appropriateness of the qualifications of existing directors, as part of the annual Board self-evaluation process. The annual self-evaluation is completed through a questionnaire process that is renewed annually to align with current regulations and best practices. The responses are collected by the Chief Legal Officer’s office and a summary of the results and comments are provided anonymously to the Governance Committee and full Board for review and consideration. This process promotes our commitment to continuous improvement and helps ensure our Board is effective.
Our self-evaluation process also aids in the Board’s succession planning by identifying any gaps in our leadership roles on the Board and its Committees. The Board values both continuity and fresh perspectives. The Company has added two new directors to the Board in the last three fiscal years, Ms. Diana S. Ferguson and Mr. José M. Gutiérrez. The Governance Committee has not specified minimum qualifications for candidates it recommends and will consider the qualifications, skills, expertise, qualities, personal backgrounds, availability and experience of all candidates that are presented for consideration. The Board seeks to have members who encompass a breadth of viewpoints, professional experience, personal backgrounds, perspectives and other individual qualities and attributes and who are best able to carry out the Board’s responsibilities. Candidates for Board nomination may be brought to the attention of the Governance Committee by current Board members, management, stockholders or other persons. All potential new candidates are fully evaluated by the Governance Committee using the criteria described above, and then considered by the entire Board for nomination.
Director Candidates submitted by Stockholders: Stockholders wishing to recommend director candidates for consideration by the Governance Committee may do so by writing to the Chairman of the Governance/Nominating Committee, c/o Corporate Secretary, Gartner, Inc., 56 Top Gallant Road, P.O.

COMPENSATION DISCUSSION & ANALYSIS
This Compensation Discussion & Analysis, or “CD&A”, describes and explains the Company’s compensation philosophy and executive compensation program, as well as compensation awarded to and earned by, the following persons who were Named Executive Officers (“NEOs”) in 2024:

Name | Position
Eugene A. Hall | Chairman of the Board & Chief Executive Officer
Craig W. Safian | Executive Vice President & Chief Financial Officer
Scott Hensel | Executive Vice President, Global Services & Delivery
Robin Kranich | Executive Vice President & Chief Human Resources Officer
Alwyn Dawkins* | Former Executive Vice President, Global Business Sales

*Mr. Dawkins stepped down as Executive Vice President, Global Business Sales on January 6, 2025 and his last day of employment with the Company was March 31, 2025.
The CD&A is organized into three sections:
•The Executive Summary (beginning on page 22), highlights the strong year we had in 2024, the importance of our Contract Value (also referred to herein as “CV”) metric, our pay-for-performance approach, and our compensation practices, all of which we believe are relevant to stockholders as they consider their votes on Proposal Two (advisory vote on executive compensation, or “Say on Pay”)
•The Compensation Setting Process for 2024 (beginning on page 25)
•Other Compensation Policies and Information (beginning on page 31)
The CD&A is followed by the Compensation Tables and Narrative Disclosures, which report and describe the compensation and benefit amounts paid to our NEOs in 2024.
EXECUTIVE SUMMARY
2024 – Strong Performance in a Complex Environment
Gartner again delivered strong performance in 2024 despite a complex environment, including worsened geopolitical polarization and conflict, and continued disruptions in supply chains and the technology sector. We performed well across our business segments. Our operating results drove stock price appreciation that significantly outpaced the S&P 500 and our peer group in the medium and long terms.
Research continued to be our largest and most profitable business segment. Research was up 5% year-over-year in revenue on a foreign exchange (“FX”) neutral basis. Contract Value, which we believe is our most important business metric, grew 8% in 2024 on an FX neutral basis. Contract Value of Global Technology Sales, or GTS, which serves executives and their teams within IT, grew 7%, while Contract Value of Global Business Sales, or GBS, which services executives and their teams beyond IT, grew 12%.
Our Conferences business also delivered strong performance in 2024. We made investments during the year for conference launches and the expansion of existing conferences. We delivered an all-time high revenue of $583 million, which was an increase of 15% on an FX neutral basis compared to 2023.
Our Consulting business, which is an important extension of our IT Research business, grew 9% in 2024 on an FX neutral basis. We exited the year with strong backlog and pipeline.

2025 Proxy Statement | 22

Compensation Discussion & Analysis

Due to a combination of strong top-line growth and continued focus on our operating expenses, we generated significant EBITDA 1 and free cash flow 2 in 2024. Our free cash flow also benefited from other items such as events cancellation insurance proceeds. We returned $735 million to stockholders through our stock repurchases.
We accomplished these strong results while also increasing our investment in our people through our benefits and compensation plans as well as ensuring we are appropriately staffed to meet our business goals. We grew our team to approximately 21,000 associates at the end of 2024.
Overall, Gartner delivered another strong year of performance in 2024. We believe we are well-prepared as we enter 2025 and are well-positioned to drive growth far into the future.
Contract Value–A Unique Key Performance Metric for Gartner

Contract Value (CV) represents the dollar value attributable to all of our subscription-related contracts. It is calculated as the annualized value of contracts in effect at a specific point in time, without regard to the duration of the contract. CV primarily includes research deliverables for which revenue is recognized on a ratable basis and other deliverables (primarily conferences tickets) included with subscription-based research products for which revenue is recognized when the deliverable is utilized.

Unique to Gartner, CV is our single most important performance metric. It focuses our executives on driving short-term actions that result in long-term success for our business and stockholders. We believe that CV growth is our best, most informed and leading indicator of long-term Research revenue growth.
Our Research business comprised 82% of our overall revenue in 2024 (83% in 2023) and is also our highest contribution margin business (74% for both 2024 and 2023). Further, the majority of our Research contracts are multi-year agreements, and our Research wallet retention is consistently high. As a result, CV is predictive of revenue highly likely to recur over a 3 – 5 year period, and a high CV growth rate translates to high, long-term revenue and profit growth. In addition, many of our clients pay us upfront when they purchase our research subscription services, which contributes to strong cash flow. For all these reasons, the Board believes that CV growth, which translates to Research revenue growth, is the most important driver of the Company’s profit growth.
Key Attributes of our Executive Compensation Program – Pay for Performance
Our executive compensation plan design has been instrumental in attracting and motivating senior management to drive outstanding corporate performance. It is heavily weighted towards incentive compensation.

Key features of our compensation program are as follows:
✓ | 100% of executive incentive awards, including annual bonus and equity awards, are performance-based or require stock price appreciation for the NEO to realize any value.
✓ | 70% of executive equity awards, and 100% of executive bonus awards vest based on performance objectives established by the Compensation Committee.
✓ | 94% of the CEO’s target total compensation (86% in the case of other NEOs) is in the form of incentive compensation (bonus and equity awards).
✓ | 87% of our CEO’s target total compensation (72% in the case of other NEOs) is in the form of equity awards, with a focus on long-term performance.
✓ | We use a longer than typical vesting period of 4 years on earned equity awards, with awards subject to increases or decreases in value based upon stock price movement to ensure alignment with stockholders over the long-term.

1 In this Proxy Statement, EBITDA refers to adjusted EBITDA, which represents GAAP net income (loss) adjusted for: (i) interest expense, net; (ii) tax provision/benefit; (iii) gain on event insurance cancellation claims, as applicable; (iv) gain/loss on divestitures, as applicable; (v) other expense/income, net; (vi) stock-based compensation expense; (vii) depreciation, amortization, and accretion; (viii) loss on impairment of lease related assets, net, as applicable; and (ix) acquisition and integration charges and certain other non-recurring items.
2 Free cash flow represents cash provided by operating activities determined in accordance with GAAP less payments for capital expenditures.

2025 Proxy Statement | 23

Compensation Discussion & Analysis

Our Compensation Best Practices
We employ compensation practices that motivate our executives to achieve Gartner’s operating plans and execute our corporate strategy without taking undue risks. These practices, which are consistent with “best practices” trends, are summarized below:

What we do
✓ | Independent Compensation Consultant. The Compensation Committee retains an independent compensation consultant to review and advise on executive compensation matters.
✓ | Risk Assessment. Annually assess the Company’s compensation policies to help avoid undue risk.
✓ | At Will Executives. All executive officers are “at will” employees with only our CEO having an employment agreement.
✓ | Performance-based Compensation. Significant portion of total compensation is performance-based, with robust performance goals.
✓ | Cap on Incentive Awards. Incentive compensation awards are capped at two times target.
✓ | Longer Vesting Compared to Industry. Equity awards vest at 25% per year over four years to encourage retention.
✓ | Stock Ownership Guidelines. Robust ownership guidelines for directors and executive officers.
✓ | Limited Perks. Benefits provided are generally consistent with other employees, with exception to the CEO’s car allowance, provided per his employment agreement.
✓ | Clawback Policy. Clawback policy applicable to executive cash bonus and performance-based restricted stock units, consistent with SEC and NYSE requirements.
✓ | Holding Requirements. 50% of net after tax shares from all released equity awards are required to be held by a Director or executive officer until stock ownership guidelines are satisfied.

What we don’t do
𝔵 | No Single-Trigger on Change in Control. Equity awards do not automatically vest on a Change in Control. Accelerated vesting is double-trigger, requiring both a change in control and qualifying termination.
𝔵 | No Hedging or Pledging. We prohibit our executives from hedging or pledging with respect to company securities.
𝔵 | No Excise Tax Gross Ups. We do not provide any tax gross ups for severance or change in control benefits provided to our executives.
𝔵 | No Equity Awards Issued to Directors or Executive Officers During Closed Trading Windows.

Effect of Stockholder Advisory Vote on Executive Compensation, or Say on Pay

2024 Say on Pay Approval = 92% of votes cast

The Board has resolved to present Say on Pay proposals to stockholders on an annual basis, respecting the sentiment of our stockholders as expressed in 2024. The Company and the Compensation Committee will consider the results of this year’s advisory Say on Pay proposal in future executive compensation planning activities. Over the past several years, stockholders have been consistent in their strong support of our executive compensation program. We also engage our stockholders from time to time to solicit their feedback on executive compensation and corporate governance matters. As such, no changes were made to the core structure of our compensation program as a result of the 2024 Say on Pay vote.

2025 Proxy Statement | 24

Compensation Discussion & Analysis

COMPENSATION SETTING PROCESS FOR 2024
This section explains the objectives of the Company’s compensation policies; what the compensation program is designed to reward; each element of compensation and why the Company chooses to pay each element; how the Company determines the amount (and, where applicable, the formula) for each element of pay; and how each compensation element and the Company’s decisions regarding that element fit into the Company’s overall compensation objectives and affect decisions regarding other elements.
The Objectives of the Company’s Compensation Policies

The objectives of our compensation policies are threefold:
➣ | To attract, motivate and retain highly talented, creative and entrepreneurial individuals by paying market-based compensation.
➣ | To motivate our executives to maximize the performance of our Company through pay-for-performance compensation components based on the achievement of corporate performance targets that are aggressive, but attainable, given economic conditions.
➣ | To seek to ensure that our compensation structure and levels are reasonable from a stockholder perspective.

What the Compensation Program Is Designed to Reward
Our guiding philosophy is to provide a significant portion of executive compensation linked to corporate performance, thereby ensuring alignment and focus on Gartner’s performance. In addition, we believe that the design of the total compensation package should be competitive with the market to attract and retain individuals who are critical to our long-term success.
Our compensation program for executive officers is designed to compensate individuals for achieving and exceeding corporate performance objectives collectively. We believe this type of compensation encourages outstanding team performance (not simply individual performance), which helps build stockholder value.
Both short-term and long-term incentive compensation is earned by executives only upon the achievement of certain measurable performance objectives that are deemed by the Compensation Committee and management to be critical to the Company’s short-term and long-term success. The amount of compensation ultimately earned will increase or decrease depending upon Company performance and the underlying price of our Common Stock (in the case of long-term equity-based incentive compensation).
Principal Compensation Elements and Objectives
To achieve the objectives noted above, our executive compensation program consists of three principal elements:

Base Salary | ➣ | Pay competitive salaries to attract and retain the executive talent necessary to develop and implement our corporate strategy and business plan.
➣ | Reflect responsibilities of the position, experience of the executive and the marketplace in which we compete for talent.
Short-Term Incentive Compensation (cash bonuses) | ➣ | Motivate executives to generate outstanding performance and achieve or exceed annual operating plan.
➣ | Align compensation with annual performance results.
Long-Term Incentive Compensation (equity awards) | ➣ | Seek to ensure rewards are commensurate with long-term performance and promote retention.
➣ | Align executive rewards with long-term stock price appreciation.
➣ | Facilitate the accumulation of Gartner shares by executives, thereby enhancing ownership and ensuring greater alignment with stockholders.

2025 Proxy Statement | 25

Compensation Discussion & Analysis

How the Company Determines Executive Compensation
In General
In early 2024, management recommended, and the Compensation Committee approved, performance objectives for short-term (bonus) and long-term (equity) incentive awards at levels that it believed would motivate performance and be adequately challenging, while also considering the economic climate and uncertainty. The target performance objectives set for 2024 were intended to drive the level of performance necessary to enable the Company to achieve its operating plan, while ensuring alignment with investor expectations.
The short-term and long-term incentive objectives provide executives with an opportunity to increase their total compensation package based upon the over-achievement of Company performance; similarly, in the case of under-achievement of Company performance, the value of incentive awards will fall below their target value, decreasing the total compensation opportunity. In addition, we assign a greater weighting to long-term awards in order to promote long-term decision-making and align management with stockholder interests and retain executives. We believe that long-term equity-based awards with vesting terms that are based on the achievement of pre-set financial targets and additional time-vesting serve as a strong retention incentive.
Determining Awards
Salary, short-term and long-term incentive compensation levels for executive officers (other than the CEO) are recommended by the CEO to the Compensation Committee, but the Compensation Committee has full authority to set such compensation. In formulating his recommendation to the Compensation Committee, the CEO undertakes a performance review of these executives and considers input from human resources personnel at the Company, as well as benchmarking data from the compensation consultant and external market data (discussed below).
The CEO’s compensation, including base salary, short-term and long-term incentive pay is established by the Compensation Committee within the parameters of Mr. Hall’s employment agreement. The Compensation Committee determines Mr. Hall’s compensation by evaluating his performance in collaboration with the Governance Committee, incorporating input from the Chairman of the Board (prior to the appointment of Mr. Hall as Chairman), Lead Independent Director (after the appointment of Mr. Hall as Chairman) and other directors. The Compensation Committee also considers insight from its compensation consultant and reviews benchmarking data on CEO compensation practices at peer companies, along with general industry trends. See Certain Employment Agreements with Executive Officers – Mr. Hall - Employment Agreement below for a detailed discussion of Mr. Hall’s agreement.
Benchmarking and Peer Group
Executive compensation planning for 2024 began mid-year in 2023. The Compensation Committee approved the peer group of companies to be used for executive compensation benchmarking purposes and other relevant analyses (the “Peer Group”) for pay decisions effective for 2024.
The Compensation Committee reviews the Peer Group annually to achieve comparability based on Gartner’s operating characteristics, labor market relevance and revenue scope. In 2023, following a review of the Peer Group, the Compensation Committee approved the Peer Group with no changes, other than the elimination of one company (Nielsen Holdings plc) due to the company going private. The remaining Peer Group includes 17 publicly-traded companies that are similar to Gartner in terms of industry, revenues, business model, and with whom Gartner competes for executive talent. At the time of the analysis, Gartner’s revenue ranked at the 53rd percentile relative to the Peer Group. The 2024 Peer Group serves as the basis of the executive benchmarking and 2024 target total compensation adjustments.

2025 Proxy Statement | 26

Compensation Discussion & Analysis

The 2024 Peer Group companies included:

Adobe Inc. |  | Akamai Technologies, Inc. |  | Aon plc |  | Autodesk, Inc. |  | Cadence Design System, Inc.
Equifax Inc. |  | Intuit Inc. |  | Moody’s Corporation |  | ServiceNow, Inc. |  | Splunk Inc.*
SS&C Technologies Holdings, Inc. |  | Synopsys Inc. |  | The Interpublic Group Companies, Inc. |  | Thomson Reuters Corporation |  | Verisk Analytics, Inc.
VMware, Inc.** |  | Workday, Inc. |  |  |  |  |  |

* Splunk Inc. was acquired in March 2024.
** VMware, Inc. was acquired in November 2023.
Our Compensation Committee commissioned Exequity, its independent compensation consultant, to perform a competitive analysis of our executive compensation practices relative to the Peer Group, as the primary comparison group, and secondarily to market survey data. Exequity’s findings were considered by the Compensation Committee and by management for 2024 executive compensation planning. The compensation study utilized market data from Aon/Radford’s Total Compensation Measurement database.
The Compensation Committee does not target NEO’s pay to a specified percentile relative to the Peer Group, but rather reviews Peer Group market data at the 25 th, 50 th and 75 th percentile for each element of compensation, including Base Salary, Target Total Cash (Base Salary plus Target Bonus) and Target Total Compensation (Target Total Cash plus target long-term incentives). Individual target total compensation may be higher or lower than the 50 th percentile based on a number of factors, including experience and tenure, retention and succession planning considerations. In addition to the compensation benchmarking, the Compensation Committee considers Company and individual performance and internal equity in evaluating and determining executive compensation recommendations.
In addition, the Compensation Committee annually reviews an analysis conducted by Exequity that evaluates the relationship between Gartner’s NEO realized pay and Company performance as measured by Total Shareholder Return and Shareholder Value creation. The analysis considers both 1-year and 3-year pay and performance for Gartner relative to the Peer Group. Exequity’s analysis indicated that pay realized by Gartner’s NEOs are aligned with Company performance.

2025 Proxy Statement | 27

Compensation Discussion & Analysis

Executive Compensation Elements Generally
Pay Mix
The following charts illustrate the mix of target compensation elements for the NEOs in 2024. Long-term incentive compensation is 100% performance-based, consisting of stock-settled stock appreciation rights (“SARs”) and performance-based restricted stock units (“PSUs”), and represents a large majority of compensation provided to our NEOs (87% to the CEO and 72% to all other NEOs). We weight compensation more heavily towards long-term incentives because it contributes to the delivery of strong performance over the long-term and the retention of employees more than any other element of compensation.
Base Salary
We set base salaries of executive officers when they join the Company or are promoted to an executive role by evaluating the responsibilities of the position, the experience of the individual (both previously and in-role at Gartner) and the marketplace in which we compete for executive talent. In addition, where possible, we consider salary information for comparable positions from our Peer Group or other available market data sources. In determining whether to award salary merit increases, we consider published projected U.S. salary increase data for the technology industry and general market, as well as available world-wide salary increase data. Mr. Hall’s base salary is established each year by the Compensation Committee after completion of Mr. Hall’s performance evaluation for the preceding year. The following table sets forth the 2023 and 2024 base salary of each NEO and the corresponding year-over-year percentage increase:

NEO | 2023 Base Salary ($) | 2024 Base Salary ($) (1) | Percentage Increase

Short-Term Incentive Compensation (Cash Bonuses)
All annual bonuses to executive officers are granted pursuant to Gartner’s Executive Performance Bonus Plan. The plan is designed to motivate executive officers to achieve goals relating to the performance of Gartner, its subsidiaries or business units, or other objectively determinable goals, and to reward them when those objectives are satisfied. We believe that the relationship between proven performance and the amount of short-term incentive compensation paid promotes, among executives, decision-making that increases stockholder value and promotes Gartner’s success.
Bonus targets for all NEOs, including Mr. Hall, were based solely upon achievement of 2024 company-wide financial performance objectives. The financial objectives and weightings used for 2024 executive officer bonuses were:

2025 Proxy Statement | 28

Compensation Discussion & Analysis

•Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA), which measures overall profitability from business operations (weighted 50%), on an FX neutral basis, and
•Revenue, which measures our ability to generate revenue growth on an annual basis (weighted 50%), on an FX neutral basis.
For 2024, each NEO was assigned a bonus target, expressed as a percentage of salary, based upon the executive’s level of responsibility and for each NEO other than Mr. Hall reflected an increase of 5% of base salary compared to 2023. The Compensation Committee approved these increases to better align with market bonus targets. Our NEOs’ 2024 annual bonus targets as a percentage of base salary were 125% for Mr. Hall; and 100% for each of Messrs. Safian, Dawkins and Hensel and Ms. Kranich. Actual awards are determined based on Company performance and can range from zero for below threshold performance to 200% of target for maximum performance, with awards capped at maximum. The following table sets forth the threshold, target and maximum payout amounts for each NEO:

NEO | Threshold ($) | Target ($) | Maximum ($)
Eugene A. Hall | 0 | 1,204,383 | 2,408,766
Craig W. Safian | 0 | 688,418 | 1,376,836
Scott Hensel | 0 | 557,291 | 1,114,582
Robin Kranich | 0 | 568,218 | 1,136,436
Alwyn Dawkins | 0 | 568,218 | 1,136,436

The chart below describes the performance metrics applicable to our 2024 short–term incentive compensation plan. The Compensation Committee believes performance goals should be rigorous, exceeding market norms, but achievable and create strong alignment between our executives and the interests of our stockholders. With respect to the performance goals for EBITDA, the Compensation Committee determined that they were appropriate after taking into consideration (1) the full year financial impact of certain 2023 actions, including significant investments in new hires, that were necessary to fuel 2024 and future growth, (2) the current economic outlook and investor expectations, and (3) the recalculation of our prior year results to eliminate foreign currency impact. In early 2024, management recommended, and the Compensation Committee approved, the EBITDA and Revenue performance goals for the 2024 short-term incentive compensation plan. The performance goals required that EBITDA, on an FX neutral basis, be above 2023 actual performance to achieve a payout above target. Similarly, the performance goals required that Revenue, on an FX neutral basis, grow at least mid-single-digit year-over-year to achieve target payout or above.
In February 2025, the Compensation Committee certified that the results for each performance metric under the bonus plan, measured on an FX neutral basis, were as follows:

2024 Performance Objective/ Weight | < Minimum (0%) | Target (100%) | =/> Maximum (200%) | Actual Results
2024 EBITDA/50% | $973 million | $1,497 million | $1,591 million | $1,586 million
2024 Revenue/50% | $5,355 million | $6,274 million | $6,474 million | $6,331 million

The EBITDA result in the table above translated to a payout percentage of 196.7%. For the Revenue component, the result above translated to a payout percentage of 128.5%. Each metric is equally-weighted, resulting in an overall result of 162.6%. The Compensation Committee approved the results and the bonus achievement for each of the NEOs. These payments were made in February 2025. See Summary Compensation Table – Non-Equity Incentive Plan Compensation for the specific cash bonuses earned by our NEOs in 2024 based on the bonus formula, actual performance and their respective bonus targets.
Long-Term Incentive Compensation (Equity Awards)
Promoting stock ownership is a key element of our compensation program philosophy. Stock-based incentive compensation helps ensure focus on value creation, promotes retention and aligns management with stockholder interests. We have evaluated different types of long-term incentives based on their motivational value, cost to the

2025 Proxy Statement | 29

Compensation Discussion & Analysis

Company and appropriate share utilization under our stockholder-approved Gartner, Inc. Long-Term Incentive Plan (the “LTIP”) and believe that SARs and PSUs create the right balance of motivation, retention and alignment with stockholders and share utilization.
SARs permit executives to realize value based on an increase in the Company’s stock price over time, promoting alignment with stockholders. SAR value can be realized only after the SAR vests. Our SARs are stock-settled with a seven-year exercise term. When the SAR is exercised, the executive receives shares of our Common Stock equal in value to the aggregate appreciation in the price of our Common Stock from the date of grant to the exercise date for all SARs exercised. Therefore, SARs only have value to the extent the price of our Common Stock exceeds the grant price of the SAR. In this way, SARs motivate our executives to increase stockholder value and thus align their interests with those of our stockholders.
PSUs offer executives the opportunity to receive our Common Stock contingent on the achievement of performance goals and continued service over the vesting period. PSU recipients are eligible to earn a target number of restricted stock units only if stipulated one-year performance goals are achieved during the year of grant. The amount of units earned can increase if the Company over-performs (up to 200% of their target number of units) or decrease (including no earning of any units) if the Company under-performs. Following the Compensation Committee’s assessment of the Company’s performance versus predetermined goals, the vesting of the units earned will remain subject to the recipient’s continued service through each of the first four anniversaries of the award grant date. PSUs encourage executives to increase stockholder value while promoting executive retention over the long-term. Earned shares have value even if our Common Stock price does not increase, which is not the case with SARs.
The Compensation Committee believes that using a one-year performance period for our PSU awards helps ensure sustained performance and factors in changes to market conditions. If we have a strong year, the goals for the following year typically are established on top of the high bar that was already set. If we instead had a three-year performance period and the Company overachieved in the first year, the bar would be set lower in years 2 and 3 and might demotivate our executives. In addition, our one-year performance period, tied to CV performance, considers multi-year revenue that is likely to occur.
The value of long-term incentive awards granted to executives each year is based on several factors, such as external market practices (including better alignment with market pay), the Company’s financial performance, the value of awards granted in prior years, succession considerations and individual performance. For 2024, the Compensation Committee increased the target value of the LTI awards for NEOs from last year based on consideration of these factors. The CEO’s target LTI award increased by 15.1%, Mr. Safian’s by 15.5%, Mr. Dawkins and Ms. Kranich’s by 16.4%, and Mr. Hensel’s by 16.3%.
Consistent with weightings in prior years, the 2024 long-term incentive plan equity mix consists of 30% SARs and 70% PSUs. PSUs deliver value utilizing fewer shares than SARs since the executive can earn the full share rather than just the appreciation in value over the grant price. Additionally, the cost efficiency of PSUs enhances the Company’s ability to conservatively utilize the LTIP share pool and helps ensure alignment between pay and Company performance. For purposes of determining the number of SARs awarded, the allocated SAR award value is divided by the Black-Scholes-Merton valuation on the date of grant using assumptions appropriate on that date. For purposes of determining the target number of PSUs awarded, the allocated target PSU award value is divided by the closing price of our Common Stock on the date of grant as reported by the New York Stock Exchange.
All SARs and PSUs vest 25% per year, commencing one year from the grant date and on each anniversary thereof, subject to continued service on the applicable vesting date, and, in the case of PSUs, the achievement of the performance goal. We believe that this vesting schedule effectively focuses our executives on delivering long-term value growth for our stockholders and drives retention. The maximum payout for the 2024 PSUs was 200% of target in the event the maximum level of CV was achieved; the PSUs were subject to forfeiture if minimum levels of performance were not achieved.

Compensation Discussion & Analysis

The chart below describes the performance metrics applicable to the PSU portion of our 2024 long–term incentive compensation element measured on an FX neutral basis. In February 2025, the Compensation Committee certified the result as follows:

2024 Performance Objective/Weight | < Minimum (0%) | Target (100%) | =/> Maximum (200%) | Actual (measured at 12/31/24) | Actual Growth YOY
Contract Value/100% | $4,392 million | $5,222 million | $5,456 million | $5,262 million | 7.8%

Based on the results set forth above, the Compensation Committee determined that 120.8% of the target number of PSUs was earned based on the preestablished performance goals, with 25% of the earned awards vested on the first anniversary of the grant date. See Grants of Plan-Based Awards Table – Possible Payouts Under Equity Incentive Plan Awards and accompanying footnotes below for the actual number of SARs and PSUs awarded to our NEOs.
Additional Compensation Elements
We maintain a non-qualified deferred compensation plan for our highly compensated employees, including our executive officers, to assist eligible participants with retirement and tax planning by allowing them to defer otherwise earned compensation in excess of amounts permitted to be deferred under our 401(k) plan. The non-qualified deferred compensation plan allows eligible participants to defer up to 50% of base salary and/or 100% of bonus to a future period. In addition, as a further inducement to participate in this plan, the Company presently matches contributions by executive officers using the same formula as for the 401(k) plan, subject to certain limits. For more information concerning this plan, see Non-Qualified Deferred Compensation Table and accompanying narrative and footnotes below.
In order to further achieve our objective of providing a competitive compensation package, we provide various other benefits to our executive officers that are typically available to others in senior business roles. Our basic executive perquisites program includes 35 days paid time off (PTO) annually, severance and change in control benefits (discussed below) and relocation services where necessary due to a promotion. Our executive officers are also entitled to participate in other benefits programs that are available to all U.S. associates, including our employee stock purchase plan and our healthcare plans, as well as to receive a 401(k) match. Executive officers may also participate in our employee charitable matching program, which is available to all employees. The Company matches charitable donations to eligible nonprofit organizations up to a specified annual limit depending on the role of the employee. For Senior Vice Presidents and above, the limit is $20,000 per year. Mr. Hall’s perquisites, severance and change in control benefits are governed by his employment agreement with the Company, which is discussed in detail below under Certain Employment Agreements with Executive Officers – Mr. Hall - Employment Agreement. For more information concerning perquisites, see Other Compensation Table and accompanying footnotes below.
OTHER COMPENSATION POLICIES AND INFORMATION
Executive Stock Ownership and Holding Period Guidelines
In order to align management and stockholder interests, the Company has adopted stock ownership guidelines for our executive officers as follows: the CEO is required to hold shares of Common Stock with a value at least equal to six times his base salary, and all other executive officers are required to hold shares of Common Stock with a value at least equal to three times their base salary. For purposes of computing the required holdings, shares directly held, as well as vested and unvested restricted stock units and earned PSUs are counted, but not options or SARs or any unearned PSUs.
Additionally, the Company imposes a holding period requirement on our executive officers if an executive officer of the Company is not in compliance with the stock ownership guidelines. In that case, the executive is required to maintain ownership of at least 50% of the net after-tax shares of Common Stock acquired from the Company pursuant to all equity-based awards received from the Company, until such individual’s stock ownership requirement is met. At December 31, 2024, all the NEOs were in compliance with our stock ownership guidelines.

Compensation Discussion & Analysis

Equity Award Grant Practices
The Company maintains a Standard Policy on Equity Award Grants (“Equity Grant Policy”), which contains general procedures regarding equity award grant practices. Under the Equity Grant Policy, the Compensation Committee approves all grants to employees who are subject to Section 16(a) of the Exchange Act (“Section 16 officers”) and the Compensation Committee has delegated the authority to our CEO to make awards to employees who are not Section 16 officers, subject to guidelines established by the Compensation Committee.
Historically, annual grants are awarded in February and are priced on the date determined by the Compensation Committee. In addition to the annual grants, stock awards may be granted at other times during the year to new hires, employees receiving promotions, and in other special circumstances. For Section 16 officers, any off-cycle awards approved by the Compensation Committee are granted and priced on the date of the Compensation Committee’s approval. For other employees, unless indicated otherwise in the Compensation Committee approval, awards are granted and priced on the 15th or 30th of the month that first follows the later of a) the CEO’s or Compensation Committee approval (as applicable) and b) the employment start date or promotion date (as applicable) (or, in each case, the next business day if such day is not a day that the New York Stock Exchange is open).
We do not grant equity awards in anticipation of the release of material, nonpublic information or time the release of material, nonpublic information based on equity award grant dates, vesting events, or sale events and do not take material nonpublic information into account when determining the timing and terms of equity awards. We have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation in fiscal year 2024.
During fiscal year 2024, we did not grant equity awards to our NEOs during the four business days prior to or the one business day following the filing of our periodic reports or the filing or furnishing of a Form 8-K that discloses material nonpublic information.
Clawback Policy
In 2023, the Company updated its Gartner, Inc. Compensation Recoupment (Clawback) Policy to comply with Dodd-Frank and the new final listing standards of the NYSE implementing Rule 10D-1. Under the Clawback Policy, in the event that the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under the federal securities laws, the Company will recover, on a reasonably prompt basis, the excess incentive-based compensation received by any current or former executive officer (including the NEOs) during the prior three fiscal years that exceeds the amount that the executive officer would have received had the incentive-based compensation been determined based on the restated financial statements. The Clawback Policy is available as an exhibit to our 2024 Annual Report on Form 10-K.
Accounting and Tax Impact
Section 162(m) of the Internal Revenue Code generally prohibits the Company from claiming a deduction on its federal income tax return for compensation in excess of $1,000,000 paid in a given fiscal year to certain current and former executive officers. While the Compensation Committee carefully considers the cost to the Company of maintaining the deductibility of all compensation, it also desires the flexibility to reward executive officers in a manner that enhances the Company’s ability to attract and retain individuals, as well as to create longer term value for stockholders. Thus, income tax deductibility is only one of several factors the Compensation Committee considers in making decisions regarding the Company’s executive compensation program.

Company until December 31, 2031 (the “CEO Agreement”). The CEO Agreement provides for automatic one year renewals commencing on January 1, 2032, and continuing each year thereafter, unless either party provides the other with at least 60 days prior written notice of an intention not to extend the term.
Under the CEO Agreement, Mr. Hall initially was entitled to the following annual compensation components:

Component | Description

| ➣ | The terms and conditions of each Annual Incentive Award will be determined by the Compensation Committee, and will be divided between RSUs units and SARs
| ➣ | The number of RSUs initially granted each year will be based upon the assumption that specified Company objectives set by the Compensation Committee will be achieved, and may be adjusted so as to be higher or lower than the number initially granted for over- or under-achievement of such specified Company objectives
Other | ➣ | Car allowance
| ➣ | All benefits provided to senior executives, executives and employees of the Company generally from time to time, including medical, dental, life insurance and long-term disability
| ➣ | Entitled to be nominated for election to the Board

Termination and Related Payments – Mr. Hall
Involuntary or Constructive Termination (no Change in Control)
Mr. Hall’s employment is at will and may be terminated by him or us upon 60 days’ notice. If we terminate Mr. Hall’s employment involuntarily (other than within 24 months following a Change In Control (defined below)) and without Business Reasons (as defined in the CEO Agreement) or a Constructive Termination (as defined in the CEO Agreement) occurs, or if the Company elects not to renew the CEO Agreement upon its expiration and Mr. Hall terminates his employment within 90 days following the expiration of the CEO Agreement, then Mr. Hall will be entitled to receive the following benefits:

Component | Termination Benefit
Base Salary | ➣ | Accrued base salary and unused paid time off (“PTO”) through termination
| ➣ | 36 months continued base salary paid pursuant to normal payroll schedule
Short-Term Incentive Award (Bonus) | ➣ | Earned but unpaid bonus
➣ | 300% of the average of Mr. Hall’s earned annual bonuses for the three years preceding termination, payable in a lump sum
Long – Term Incentive Award | ➣ | 36 months’ continued vesting in accordance with their terms (including achievement of applicable performance objectives) of all outstanding equity awards
➣ | If in the year of termination there are Annual LTI Awards due to be granted that have not yet been granted, a lump sum payment in cash equal to the value of any “to-be-granted” Annual LTI Awards, multiplied by the percentage of such award that would vest within 36 months following termination (i.e., 75% in the case of a four-year vesting period)
Other | ➣ | Reimbursement for up to 36 months’ COBRA premiums for Mr. Hall and his family

2025 Proxy Statement | 37

Compensation Tables and Narrative Disclosures

Payment of severance amounts is conditioned upon execution of a general release of claims against the Company and compliance with 36-month non-competition and non-solicitation covenants. In certain circumstances, payment will be delayed for six months following termination under Code Section 409A.
Involuntary or Constructive Termination, and Change in Control
Within 24 months following a Change in Control: if Mr. Hall’s employment is terminated involuntarily and without Business Reasons; or a Constructive Termination occurs; or if the Company elects not to renew the CEO Agreement upon its expiration and Mr. Hall terminates his employment within 90 days following the expiration of the CEO Agreement (i.e., a double trigger termination), Mr. Hall will be entitled to receive the following benefits:

Component | Termination Benefit
Base Salary | ➣ | Accrued base salary and unused PTO through termination
➣ | 3 times base salary then in effect, payable 6 months following termination
Short-Term Incentive Award (Bonus) | ➣ | Any earned but unpaid bonus
➣ | 3 times target bonus for fiscal year in which Change in Control occurs, payable 6 months following termination
Long – Term Incentive Award | ➣ | Any due to be granted Annual LTI Awards pursuant to the CEO Agreement will be granted
➣ | All unvested outstanding equity awards will have the service requirement deemed fully satisfied, all performance goals or other vesting criteria will be deemed achieved (i) if the performance period has been completed, at actual level of performance, or (ii) if the performance period has not been completed, at target level of performance, and all stock options and SARs will be exercisable as to all covered shares
Other | ➣ | Reimbursement for up to 36 months’ COBRA premiums for Mr. Hall and his family

Mr. Hall’s unvested outstanding equity awards will only vest in connection with a Change in Control if Mr. Hall’s employment is terminated under the circumstances described above within 24 months following the Change in Control (i.e., if a “double trigger” occurs).
Should any payments received by Mr. Hall upon a Change in Control constitute a “parachute payment” within the meaning of Code Section 280G, Mr. Hall may elect to receive either the full amount of his Change in Control payments, or such lesser amount as will help ensure that no portion of his severance and other benefits will be subject to excise tax under Code Section 4999. The CEO Agreement does not provide for a gross-up of these taxes. Additionally, certain payments may be delayed for six months following termination under Code Section 409A.
The CEO Agreement utilizes the LTIP definition of “Change in Control” which currently provides that a Change in Control will occur when (i) there is a change in ownership of the Company such that any person (or group) becomes the beneficial owner of 50% of our voting securities, (ii) there is a change in the ownership of a substantial portion of the Company’s assets or (iii) there is a change in the effective control of the Company such that a majority of members of the Board is replaced during any 12 month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of appointment or election.
In the CEO Agreement, Mr. Hall is subject to certain restrictive covenants, including an indefinite confidentiality provision as well as provisions providing for a non-compete, non-solicit of employees, customers, and suppliers, and non-disparagement of the Company and its executives and directors that applies during employment and for 36 months following the termination thereof.
Termination and Related Payments – Other Executive Officers
In the event of termination for cause, voluntary resignation or as a result of death, disability or retirement, no severance benefits are provided. In the event of termination for cause or voluntary resignation, all equity awards are forfeited except

2025 Proxy Statement | 38

Compensation Tables and Narrative Disclosures

as discussed below under Death, Disability and Retirement. In the event of termination without cause (including in connection with a Change in Control), other executive officers are entitled to receive the following benefits:

Component | Termination Benefit
Base Salary | ➣ | Accrued base salary and unused PTO (not to exceed 25 days) through termination
➣ | 12 months continued base salary paid pursuant to normal payroll schedule
Long–Term Incentive Awards | ➣ | In the event of a termination without cause within 12 months following a Change in Control, all unvested outstanding equity will vest in full. For any PSU award where performance has not yet been determined, the award will vest assuming target performance, and all stock options and SARs will be exercisable as to all covered shares for 12 months following termination; otherwise unvested awards are forfeited
➣ | If no Change in Control, unvested equity awards are forfeited (except in the case of death, disability and retirement, discussed below)
Other | ➣ | Reimbursement for up to 12 months’ COBRA premiums for executive and family

In order to receive severance benefits, the executive officers who are terminated are required to execute and comply with a separation agreement and release of claims in which, among other things, the executive reaffirms his or her commitment to confidentiality, non-competition and non-solicitation obligations and releases the Company from various employment-related claims. In addition, in the case of NEOs (other than Mr. Hall), severance will not be paid to any executive who refuses to accept an offer of comparable employment from Gartner or who does not cooperate or ceases to cooperate when being considered for a new position with Gartner, in each case as determined by the Company. Finally, under certain circumstances, payments and release of shares may be delayed for six months following termination under Code Section 409A.
Death, Disability and Retirement
Our executive officers are entitled to immediate vesting of all outstanding awards in the case of termination due to death or disability, and continued vesting depending upon the age of the officer in the case of retirement (as defined) as described in the following table:

Termination Event | Treatment of Unvested Equity Awards
Death or Disability | ➣ | 100% vesting upon event
Retirement – not eligible | ➣ | Unvested awards forfeited
Retirement – eligible | ➣ | Unvested awards continue to vest in full in accordance with their terms (subject to certain conditions)
➣ | Retirement eligible if on the date of retirement, the officer is at least 55 years old and has at least 10 years of service | ➣ | For a retirement in the year that an award is granted, the unvested portion of such award that is eligible to vest will be prorated based on the number of days in the year of grant during which the officer was employed

In order to receive retirement vesting, an officer must be retirement “eligible” on the date of retirement, as described in the table above; if not, all unvested awards are forfeited upon retirement. At December 31, 2024, only Messrs. Hall, Safian and Dawkins would have qualified for the additional vesting benefit upon retirement for their outstanding equity awards. Disability is defined in our current equity award agreements as total and permanent disability.
SARs remain exercisable through the earlier of the applicable expiration date or one year from termination in the case of death and disability, and through the expiration date in the case of retirement. Upon termination for any other reason, vested SARs remain exercisable through the earlier of the applicable expiration date or 90 days from the date of termination.
In the case of death, disability or retirement, unvested PSUs held by an officer that are eligible to vest will be earned, if at all, based upon achievement of the related performance metric upon certification by the Compensation Committee.

Outstanding Equity Awards at Fiscal Year-End December 31, 2024
This table provides information on each option (including SARs) and stock (including RSUs and PSUs) awards held by each NEO as of December 31, 2024. All performance criteria associated with these awards (except for the 2024 PSU award (see footnote 4)) were fully satisfied as of December 31, 2024, and the award is fixed. The market value of the stock awards is based on the closing price of our Common Stock on the NYSE on December 31, 2024 (the last business day of the year), which was $484.47. Upon exercise of, or release of restrictions on, these awards, the number of shares ultimately issued to each executive will be reduced by the number of shares withheld by Gartner for tax withholding purposes and/or as payment of the exercise price in the case of options and SARs.

Non-Qualified Deferred Compensation for Fiscal Year 2024
The Company maintains a Non-Qualified Deferred Compensation Plan for certain officers and key personnel whose compensation grade profile was a 130 or higher in 2024, or those who have been previously grandfathered into the plan. This plan currently allows qualified U.S.-based employees to defer up to 50% of earned annual salary and/or up to 100% of annual bonus earned in a fiscal year. In addition, in 2024 the Company made a contribution to the account of each NEO who deferred compensation equal to the amount of such executive’s contribution (not to exceed 4% of base salary and bonus), less $7,200. Deferred amounts are deemed invested in several independently-managed investment portfolios selected by the participant for purposes of determining the amount of earnings to be credited by the Company to that participant’s account. The Company may, but need not, acquire investments corresponding to the participants’ designations.
Upon termination of employment for any reason, all account balances will be distributed to the participant in a lump sum, except that a participant whose account balance is in excess of $25,000 may defer distributions for an additional year, and/or elect to receive the balance in 20, 40 or 60 quarterly installments. In the event of an unforeseen emergency (which includes a sudden and unexpected illness or accident of the participant or a dependent, a loss of the participant’s property due to casualty or other extraordinary and unforeseeable circumstance beyond the participant’s control), the participant may request early payment of his or her account balance, subject to approval.
The following table provides information (in dollars) concerning contributions to the Deferred Compensation Plan in 2024 by the participating Named Executive Officers, the Company’s matching contributions, 2024 earnings, aggregate withdrawals and distributions and account balances at year-end:

Potential Payments upon Termination or Change in Control
Certain Employment Agreements with Executive Officers above contains a detailed discussion of the payments and other benefits to which our CEO and other NEOs are entitled in the event of termination of employment or upon a Change in Control. The amounts payable assuming termination under various circumstances at December 31, 2024 are set forth below. In the event of termination of employment or a termination in connection with a Change in Control, each NEO would also be entitled to receive accrued personal time off (PTO) and the balance in his or her deferred compensation plan account. Such accrued amounts are not quantified below. There is no vesting of equity awards for our NEO’s based solely upon a Change in Control (i.e., without termination).

The table below quantifies (in dollars) amounts that would be payable by the Company to Mr. Hall, and the value of shares of Common Stock underlying the equity awards that would vest, had his employment been terminated on December 31, 2024 (the “Termination Date”) as a result of (1) involuntary termination without cause and/or constructive termination; (2) death, disability or retirement; or (3) an involuntary termination without cause and/or constructive termination in the 24 months following a Change in Control (“Hall Double Trigger Termination”). Mr. Hall would not receive any payment or vesting of equity awards in the event of a Change in Control only (i.e., without termination).

Pay Ratio
The 2024 annual total compensation of the median compensated of all our employees who were employed as of December 31, 2024, other than our Chairman and CEO, Mr. Hall, was $123,618; Mr. Hall’s 2024 annual total compensation was $18,352,293 and the ratio of these amounts was 1-to-148.
The SEC’s rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.
The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records, and the methodology described herein. For these purposes, we identified the median compensated employee using the base salary determined as of December 31, 2024, and target cash incentives for the 2024 performance year, which amounts were annualized for any permanent (that is, non-temporary) employee who did not work for the entire year. We considered all of our worldwide associates employed with us as of December 31, 2024, when examining the pay ratio, including in determining the median compensated employee. Based on our consistently applied compensation measure, we identified a group of 10 associates within 0.2% of the median amount and calculated annual total compensation in accordance with the Summary Compensation Table requirements for these associates to identify our median compensated employee.
Pay Versus Performance
The following table and disclosures have been prepared in accordance with the Pay Versus Performance SEC disclosure rules, pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act. The table discloses information on “compensation actually paid” (CAP) to our principal executive officer (PEO) and to our other NEOs (non-PEO NEOs) for 2020 to 2024, alongside total shareholder return (TSR), net income, and the Company’s selected metric of CV. CV is the most important metric in linking compensation actually paid to our NEOs to Company performance, representing 70% of long-term incentive awards granted to our NEOs for 2024.

(i) The fair value or incremental fair value of all incentive equity awards is determined in accordance with ASC 718, using materially the same methodologies used in determining the grant date fair value of our equity awards reflected in the Summary Compensation Table; provided, in order to properly value the SAR awards using the Black-Scholes model we use for such grant date fair value, we made appropriate adjustments to the grant date assumptions to reflect changes in the historical and implied stock price volatility, expected life (including remaining vesting periods, remaining expiration periods and SAR gain levels), dividend yield and risk-free interest rates as of each measurement date. The value of outstanding performance-based awards in the covered fiscal year is based upon the probable outcome of the performance conditions as of the last day of the fiscal year.

As of December 31, 2024, there were a total of 4,601 Company shares subject to assumed CEB restricted stock units. No additional restricted stock units, options or other awards have been granted under the CEB Plan since the closing of the acquisition and no new awards will be granted in the future under that plan.

PROPOSAL TWO:
APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
In accordance with the requirements of Section 14A of the Exchange Act (which was added by the Dodd-Frank Act) and the related rules of the SEC, we are including in this Proxy Statement a separate resolution subject to stockholder vote to approve the compensation of our NEOs (“say-on-pay”). At the 2023 annual meeting, the Board recommended and stockholders approved holding this advisory vote on an annual basis. Accordingly, you are being asked to vote on the following resolution at the 2025 Annual Meeting:
Resolved, that the compensation of Gartner’s Named Executive Officers as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved on an advisory basis.
The stockholder vote on this resolution is advisory only. However, the Compensation Committee and the Board will consider the voting results when making future executive compensation decisions.
In considering your vote, stockholders may wish to review with care the information on Gartner’s compensation policies and decisions regarding the NEOs presented in the CD&A on pages 22-32, including, in particular, the information concerning Company performance included in the Executive Summary on pages 22-24 and highlights of our Compensation Practices on page 23.
In particular, stockholders should note that the Compensation Committee bases its executive compensation decisions on the following:

➣ | the need to attract, motivate and retain highly talented, creative and entrepreneurial individuals in a highly competitive industry and marketplace;
➣ | the need to motivate our executives to maximize the performance of our Company through pay-for-performance compensation components which have led executives to deliver outstanding performance for the past several years;
➣ | comparability to the practices of peers in our industry and other comparable companies generally based upon available benchmarking data; and
➣ | the alignment of our executive compensation programs with stockholder value through heavily weighted performance-based compensation elements.

As noted in the Executive Summary commencing on page 22, 2024 was a year of strong performance for Gartner despite multiple global disruptions. We believe this strong performance is largely a result of the agility, focus and skill of our executive leadership team. The Board believes that Gartner’s executive compensation program has a proven record of effectively driving superior levels of financial performance, stockholder value, alignment of pay with performance, high ethical standards and attraction and retention of highly talented executives.
The Board of Directors has adopted a policy providing for annual say-on-pay advisory votes. Unless the Board of Directors modifies its policy on the frequency of holding say-on-pay advisory votes, the next say-on-pay advisory vote following the 2025 Annual Meeting will occur in 2026.

VOTE RECOMMENDATION OF OUR BOARD: FOR | Our Board unanimously recommends that you vote FOR the foregoing resolution to approve, on an advisory basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement.

2025 Proxy Statement | 49

Proposal Three: Ratification of Appointment of Independent Registered Public Accounting Firm

Pre-Approval Policies
The Audit Committee’s policy is to pre-approve all audit engagement fees and terms as well as all non-audit engagements performed by KPMG. These services may include domestic and international audit services, audit-related services, tax services and other services. At the beginning of each fiscal year, the Audit Committee pre-approves aggregate fee limits for specific types of permissible services (e.g., domestic and international tax compliance and tax planning services; transfer pricing services, audit-related services and other permissible services) to allow management to engage KPMG expeditiously as needed when projects arise. At each regular quarterly meeting, KPMG and management report to the Audit Committee regarding the services for which the Company has engaged KPMG in the immediately preceding fiscal quarter in accordance with the pre-approved limits, and the related fees for such services as well as year-to-date cumulative fees for KPMG services. Pre-approved limits may be adjusted as necessary during the year, and the Audit Committee may also pre-approve particular services on a case-by-case basis. All services provided by KPMG in 2024 were pre-approved by the Audit Committee.
AUDIT COMMITTEE REPORT
Pursuant to its responsibilities as set forth in the Audit Committee Charter, the Audit Committee has reviewed and discussed with management and with KPMG Gartner’s audited consolidated financial statements for the year ended December 31, 2024. The Audit Committee has discussed with KPMG the matters required to be discussed under applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the Securities and Exchange Commission. The Audit Committee has received the written disclosures and letter from KPMG required by applicable requirements of the PCAOB regarding KPMG’s communications with the Audit Committee concerning independence and has discussed with KPMG that firm’s independence.
Based on the review and discussions noted above, as well as discussions regarding Gartner’s internal control over financial reporting and discussions with Gartner’s internal audit function, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements for the year ended December 31, 2024 be included in Gartner’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 for filing with the Securities and Exchange Commission.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
Based on our review of information on file with the SEC and our stock records, the following table provides certain information about beneficial ownership of shares of our Common Stock as of April 4, 2025 (including shares that will release or are or will become exercisable within 60 days following April 4, 2025) held by: (i) each person (or group of affiliated persons) which is known by us to own beneficially more than five percent (5%) of our Common Stock; (ii) each of our directors; (iii) each NEO; and (iv) all directors, NEOs and other current executive officers as a group. Percentage computations are based on 77,059,204 shares of Common Stock outstanding on April 4, 2025. Unless otherwise indicated, the address for those listed below is c/o Gartner, Inc., 56 Top Gallant Road, Stamford, CT 06902. The amounts shown do not include CSEs or RSUs that release upon termination of service as a director, or deferred CSEs or RSUs that will not release within 60 days. Since all stock appreciation rights (SARs) are stock-settled (i.e., shares are withheld for the payment of exercise price and taxes), the number of shares ultimately issued upon settlement will be less than the number of SARs exercised. Except as indicated by footnote, and subject to applicable community property laws, the persons named in the table directly own, and have sole voting and investment power with respect to, all shares of Common Stock shown as beneficially owned by them. To the Company’s knowledge, none of these shares has been pledged.

TRANSACTIONS WITH RELATED PERSONS
Gartner delivers actionable, objective insight to executives and their teams for close to 14,000 enterprises in approximately 90 countries and territories — across all major functions, in every industry and enterprise size. Because of our worldwide reach, it is not unusual for Gartner to engage in ordinary course of business transactions involving the sale of research or consulting services with entities in which one of our directors, executive officers or a greater than 5% owner of our stock, or immediate family member of any of them, may also be a director, executive officer, partner or investor, or have some other direct or indirect interest. We will refer to these transactions generally as related party transactions.
The Audit Committee is charged with monitoring and reviewing issues involving potential conflicts of interest and reviewing and approving related person transactions. The Audit Committee has adopted a written Related Person Transaction Policies and Procedures (the “RPT Policy”), which require the Audit Committee to review and approve transactions in which (i) the aggregate amount involved is or is expected to exceed $120,000, (ii) the Company or any of its subsidiaries is a participant, and (iii) any related person has a direct or indirect interest. Under the RPT Policy, related persons include (i) any person who is or was during the last fiscal year a director, executive officer, or any nominee for director, (ii) any person owning 5% or more of the Company’s Common Stock, and (iii) any immediate family members of such persons. Under the RPT Policy, the Audit Committee has pre-approved several categories of transactions with related persons. For transactions that are not pre-approved under the Policy, in reviewing and determining whether to approve related person transactions, the Audit Committee takes into account whether the transaction is available to an unaffiliated third party under the same or similar circumstances, the extent of the related person’s interest in the transaction, and other factors as the Audit Committee deems appropriate. The Audit Committee will not approve any related person transaction if it determines it to be inconsistent with the interests of the Company and its stockholders.
In addition, the Company maintains a written conflict of interest policy, which is posted on our intranet. The conflict of interest policy prohibits all Gartner employees, including our executive officers, from engaging in any personal, business or professional activity which conflicts with or appears to conflict with their employment responsibilities and from maintaining financial interests in entities that could create an appearance of impropriety in their dealings with the Company. Additionally, the policy prohibits all Gartner employees from entering into agreements on behalf of Gartner with any outside entity if the employee knows that the entity is a related party to a Gartner employee; i.e., that the contract would confer a financial benefit, either directly or indirectly, on a Gartner employee or his or her relatives. All potential conflicts of interest involving Gartner employees must be reported to, and pre-approved by the Chief Legal Officer or their designee.
Since January 1, 2024, there were no related party transactions in which any director, executive officer or a greater than 5% owner of our stock, or immediate family member of any of them, had or will have a direct or indirect material interest.
DELINQUENT SECTION 16(a) REPORTS
Section 16(a) of the Exchange Act requires our executive officers, directors and persons who beneficially own more than 10% of our Common Stock to file reports of ownership and changes of ownership with the SEC and to furnish us with copies of the reports they file. To assist with this reporting obligation, the Company prepares and files ownership reports on behalf of its executive officers and directors pursuant to powers of attorney issued by the executive officer or director to the Company. Based solely on our review of the filed reports made since January 1, 2024, or written representations from certain reporting persons, we believe that all such reporting persons filed the required reports on a timely basis under Section 16(a), except that (1) a Form 4 was filed late, due to an administrative error, on behalf of Mr. Dawkins to report one transaction, and (2) a Form 4 was filed late, due to an administrative error, on behalf of Ms. Genovese to report one transaction.

PROXY AND VOTING INFORMATION
Information Concerning Proxy Materials and the Voting of Proxies
How can I participate in the 2025 Annual Stockholders’ Meeting?
To be admitted to the Annual Meeting, please visit www.virtualshareholdermeeting.com/IT2025. Online check-in will be available approximately 15 minutes before the meeting starts. Stockholders of record as of the close of business on April 4, 2025, the Record Date, are entitled to participate in and vote at the Annual Meeting. To participate in the Annual Meeting, including to vote, and ask questions during the Annual Meeting, stockholders of record should go to the meeting website at www.virtualshareholdermeeting.com/IT2025, enter the 16-digit control number found on your proxy card or Notice of Internet Availability of Proxy Materials (the “Notice”), and follow the instructions on the website. If your shares are held in street name and your voting instruction form or Notice indicates that you may vote those shares through the http://www.proxyvote.com website, then you may access, participate in, and vote at the annual meeting with the 16-digit access code indicated on that voting instruction form or Notice. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least 5 days before the Annual Meeting) and obtain a “legal proxy” in order to be able to attend, participate in or vote at the Annual Meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be provided on the log-in page.
Stockholders may submit questions during the Annual Meeting. Questions may be submitted during the Annual Meeting at www.virtualshareholdermeeting.com/IT2025. The company will try to answer as many questions as possible during the time scheduled. Additional information regarding the question and answer process, including the types and number of questions permitted, and the time allotted for the question and answer session, will be available in the Annual Meeting rules of conduct and procedures, which will be posted at the virtual Annual Meeting website during the Annual Meeting.
Why is it Important to Vote?
Voting your shares is important to ensure that you have a say in the governance of the Company. Additionally, repeated failure to vote may subject your shares to risk of escheatment. Please review the proxy materials and follow the relevant instructions to vote your shares. We hope you will exercise your rights and fully participate as a stockholder in the future of Gartner.
Why Did You Receive a Notice Regarding Availability of Proxy Materials?
The Securities and Exchange Commission (“SEC”) rules allow companies to furnish proxy materials to their stockholders via the Internet. This “e-proxy” process expedites stockholders’ receipt of proxy materials, while significantly lowering the costs and reducing the environmental impact of our annual meeting. Accordingly, on April 15, 2025, we mailed to our stockholders (other than those who previously have requested printed proxy materials) a Notice. If you received a Notice, you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access our proxy materials for the Annual Meeting on a website, how to request a printed copy of the proxy materials and how to vote your shares. We will mail printed copies of our proxy materials to those stockholders who have already elected to receive printed proxy materials.
If Your Shares Are Held in “Street Name,” How Are Your Shares Voted?
If you are the beneficial owner of shares (meaning that your shares are held in the name of a bank, brokerage or other nominee; i.e., “street name” accounts), you may receive a Notice from that firm containing instructions you must follow in order for your shares to be voted. Additionally, brokers are not permitted to vote on certain items, and may elect not to vote on any of the items, unless you provide voting instructions. A broker “non-vote” occurs when a nominee (such as a bank, broker or other nominee) holding shares for a beneficial owner does not vote on a particular item because the nominee does not have discretionary voting power for that particular matter and has not received instructions from the beneficial owner. Broker non-votes will not be tabulated in determining whether any of the items presented at the Annual Meeting has obtained the requisite vote to be approved. We urge you to promptly provide voting instructions to your broker to ensure that your shares are voted on all of the proposals, even if you plan to attend the annual meeting.
If You Are the Holder of Record of Your Shares, How Are Your Shares Voted?
If you are the holder of record of your shares, you will either receive a Notice or printed proxy materials if you have already elected to receive printed materials. The Notice will contain instructions you must follow to vote your shares. If you

Proxy and Voting Information

received proxy materials in paper form, the materials include a proxy card instructing the holder of record how to vote the shares.
How Can You Get Electronic Access to Proxy Materials?
The Notice provides instructions regarding how to view our proxy materials for the Annual Meeting online. Additionally, proxy materials are available on www.proxyvote.com, 24 hours a day, seven days a week. You will need the control number(s) located on your Notice to access the proxy materials online.
How Can You Request Paper or Email Copies of Proxy Materials?
If you received a Notice by mail, you will not receive a printed copy of the proxy materials. If you want to receive paper or email copies of the proxy materials, you must request them. There is no charge for requesting a copy. To facilitate timely delivery, please follow the instructions included in the Notice.
How Can You Sign Up to Receive Future Proxy Materials Electronically?
You have the option to receive all future proxy statements, proxy cards and annual reports electronically via email or the Internet. If you elect this option, the Company will only mail printed materials to you in the future if you request that we do so. To sign up for electronic delivery, please follow the instructions below under How Can You Vote to vote using the Internet and vote your shares. After submitting your vote, follow the prompts to sign up for electronic delivery.
What is “Householding”?
We have adopted “householding” procedures that allow us to deliver proxy materials more cost-effectively. If you are a beneficial owner of shares and you and other residents at your mailing address share the same last name and also own shares of common stock in an account at the same bank, brokerage, or other nominee, your nominee delivered a single Notice or set of proxy materials to your address. This method of delivery is known as householding. Householding reduces the number of mailings you receive, saves on printing and postage costs and helps the environment. Stockholders participating in householding continue to receive separate proxy cards and control numbers for voting electronically.
We will deliver promptly a separate copy of the Notice or proxy materials to a stockholder at a shared address to which a single copy was delivered. A stockholder who received a single Notice or set of proxy materials to a shared address may request a separate copy of the Notice or proxy materials be sent to him or her by contacting in writing to Broadridge Financial Solutions, Inc. (“Broadridge”), Householding Department at 51 Mercedes Way, Edgewood, New York, 11717, or calling 1-866-540-7095. If you would like to opt out of householding for future deliveries of proxy materials, please contact your broker, bank or other nominee.
Beneficial owners of shares who share an address and receive multiple copies of the proxy materials but want to receive only a single copy of these materials in the future should contact their bank, brokerage or other nominee and make this request.
Who Can Vote at the Annual Meeting?
Only stockholders of record at the close of business on April 4, 2025 (the “Record Date”) may vote at the Annual Meeting. As of the Record Date, there were 77,059,204 shares of Common Stock outstanding and eligible to be voted. This amount does not include treasury shares which are not voted.

All shares that have been voted properly by an unrevoked proxy will be voted at the Annual Meeting in accordance with your instructions. If you sign and submit your proxy card, but do not give voting instructions, the shares represented by that proxy will be voted for each proposal as our Board recommends.
How to Revoke Your Proxy or Change Your Vote
A later vote by any means will cancel an earlier vote. You can revoke your proxy or change your vote before your proxy is voted at the Annual Meeting by giving written notice of revocation to: Corporate Secretary, Gartner, Inc., 56 Top Gallant Road, P.O. Box 10212, Stamford, Connecticut 06904-2212; or submitting another timely proxy by the Internet, telephone or mail; or voting at the Annual Meeting. If your shares are held in the name of a bank, broker or other holder of record, you may revoke your proxy or change your vote by contacting your bank, broker or other holder of record or by voting at the Annual Meeting. Attendance at the Annual Meeting will not, by itself, revoke your prior proxy.
How Many Votes You Have
Each stockholder has one vote for each share of our Common Stock owned on the Record Date for all matters being voted on.
Quorum
A quorum is constituted by the presence, in person or by proxy, of holders of our Common Stock representing a majority of the number of shares of Common Stock entitled to vote. Abstentions and broker non-votes (described above) will be considered present to determine a quorum.

2025 Proxy Statement | 56

Proxy and Voting Information

Votes Required

Proposal | Vote Required
1 | Election of each of the eleven nominees to our Board of Directors | Majority of votes cast
2 | Approval, on an advisory basis, of the compensation of our named executive officers | Majority of shares present and entitled to vote
3 | Ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the 2025 fiscal year | Majority of shares present and entitled to vote

Proposal One: Each nominee must receive more “FOR” votes than “AGAINST” votes to be elected. Abstentions and broker non-votes will have no effect on the outcome of the election. Any nominee who fails to achieve this threshold is expected to tender his or her resignation from the Board pursuant to the Company’s majority vote standard.
Proposals Two and Three: The affirmative “FOR” vote of a majority of the shares of Common Stock present in person or represented by proxy and entitled to vote is required to approve Proposal Two—the advisory (non-binding) approval of the Company’s executive compensation; and Proposal Three—the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025. For Proposals Two and Three, abstentions have the same effect as “AGAINST” votes. Broker non-votes, if any, will have no effect on the outcome of these matters.
If any other matters are brought properly before the Annual Meeting, the persons named as proxies in the accompanying proxy card will have the discretion to vote on those matters for you. If for any reason any of the nominees is not available as a candidate for director at the Annual Meeting, the persons named as proxies will vote your proxy for such other candidate or candidates as may be nominated by the Board of Directors. As of the date of this Proxy Statement, we were unaware of any other matter to be raised at the Annual Meeting.
What Are the Recommendations of the Board?
The Board of Directors recommends that you vote:

Who Is Distributing Proxy Materials and Bearing the Cost of the Solicitation?
This solicitation of proxies is being made by the Board of Directors and we will bear the entire cost of this solicitation, including costs associated with mailing the Notice and related Internet access to proxy materials, the preparation, assembly, printing, and mailing of this Proxy Statement, the proxy card, and any additional solicitation material that we may provide to stockholders. Gartner will request brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others to solicit proxies from these persons and will pay the costs associated with such activities. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic mail and other means by our directors, officers and employees. No additional compensation will be paid to these individuals for any such services. We have also retained Georgeson LLC to assist with the solicitation of proxies at an anticipated cost of $8,000, which will be paid by the Company.
