MARKET OVERVIEW

Enterprise leaders face enormous pressure to stay ahead and grow profitably amidst constant change. Whether it is a digital transformation, cybersecurity risk mitigation, supply chain disruptions, large-scale regulatory changes, or other unique challenges, business leaders today are facing significant disruptive changes. We believe that enterprises cannot be operationally effective unless they incorporate the right strategy, management and technology decisions into every part of their business. This requirement affects all executives in every major function, enterprise size, geography, industry and market sector. Executives and their teams turn to Gartner for actionable, objective insight that drives smarter decisions and stronger performance on their mission-critical priorities.

OUR SOLUTION

We believe our combination of expert-led, practitioner-sourced and data-driven research steers clients toward the right decisions and actions on the issues that matter most. Organizations are overrun with data and information. Gartner helps eliminate this information chaos and provides clarity with actionable, objective insight. We employ a diversified business model that utilizes and leverages the breadth and depth of our differentiated intellectual capital. The foundation of our business model is our ability to create and distribute our proprietary research content as broadly as possible via published reports, interactive tools, facilitated peer networking, briefings and direct communications with executives and their teams; our conferences, including the Gartner Symposium/Xpo series; and consulting and advisory services.

PRODUCTS AND SERVICES

Our diversified business model provides multiple entry points and sources of value for our clients that lead to increased client spending on our research and advisory services, conferences and consulting services. A critical part of our long-term strategy is to increase business volume and penetration with our most valuable clients, identifying relationships with the greatest sales potential and expanding those relationships by offering strategically relevant research and insight. We also seek to extend the Gartner brand name to develop new client relationships, augment our sales capacity and expand into new markets around the world. These initiatives have created additional revenue streams through more effective packaging, campaigning and cross-

selling of our products and services. In addition, we seek to increase our revenue and operating cash flow through more effective pricing of our products and services.

Our principal products and services are delivered through our three business segments, as described below.

• RESEARCH.** Gartner delivers independent, objective insight to leaders across an enterprise through subscription services that include on-demand access to published research content, data and benchmarks, and direct access to a network of more than 2,500 research experts located around the globe. Gartner research is the fundamental building block for all Gartner products and services. We combine our proprietary research methodologies with extensive industry and academic relationships to create Gartner products and services that address each role across an enterprise. Within the Research segment, Global Technology Sales (“GTS”) sells products and services to users and providers of technology, while Global Business Sales (“GBS”) sells products and services to all other functional leaders, such as human resources, supply chain, finance, and marketing.

Our research agenda is defined by clients’ needs, focusing on the critical issues, opportunities and challenges they face every day. We are in steady contact with close to 14,000 distinct client enterprises worldwide. We publish tens of thousands of pages of original research annually, and our research experts had more than 505,000 direct client interactions in 2024. Our size and scale enable us to commit vast resources toward broader and deeper research coverage and to deliver insight to our clients based on what they need and where they are. The ongoing interaction of our research experts with our clients enables us to identify the most pertinent topics to them and develop relevant product and service enhancements to meet the evolving needs of users of our research. Our proprietary research content, presented in the form of reports, briefings, updates and related tools, is delivered directly to the client’s computer or mobile device via our website and/or product-specific portals.

Clients normally sign subscription contracts that provide access to our research content and advisory services for individual users over a defined period. We typically have a minimum contract period of twelve months for our research and advisory subscription contracts and, at December 31, 2024, nearly 75% of our contracts were multi-year.

• CONFERENCES.** Gartner conferences are designed for information technology (“IT”) and business executives as well as other decision makers looking to adapt and evolve their organizations through disruption and uncertainty, navigate risks and prioritize investments. Attendees experience sessions led by Gartner research experts, and the sessions include cutting-edge technology solutions, peer exchange workshops, one-on-one analyst and advisor meetings, consulting diagnostic workshops, keynotes and more. Our conferences also provide attendees with an opportunity to interact with IT and business executives from the world’s leading companies. In addition to role-specific summits and workshop-style seminars, Gartner hosts the Gartner Symposium/Xpo series, including its unique, flagship IT Symposium/Xpo®, which is held at several locations worldwide annually. During 2024, Gartner successfully held 51 in-person conferences with more than 86,000 attendees, including nine Symposiums/Xpos. In addition, during 2024 we hosted 200+ peer networking meetings and 400+ exclusive local C-level meetings with more than 200 in-person.

• CONSULTING.** Through its experienced consultants, Gartner Consulting serves chief information officers and other senior executives who are driving technology-related strategic initiatives to optimize technology investments and drive business impact. Gartner Consulting combines the power of Gartner’s market-leading research with custom analysis and on-the-ground support to help clients to turn insight and advice into action and impact.

Consulting solutions capitalize on Gartner assets that are invaluable to IT decision-making, including: (1) our extensive research, which ensures that our consulting analyses and advice are based on a deep understanding of the IT environment and the business of IT; (2) our market independence, which keeps our consultants focused on our clients’ success; and (3) our market-leading benchmarking capabilities, which provide relevant comparisons and best practices to assess and improve performance. Additionally, we provide actionable solutions for a range of IT-related priorities, including IT cost optimization, digital transformation and IT sourcing optimization.

COMPETITION

We believe that the principal factors that differentiate us from our competitors are as follows:

• Superior research content - We believe that we create the broadest, highest-quality and most relevant research coverage across all major functional roles in an enterprise. Our independent operating model and research analysis generates

unbiased insight that we believe is timely, thought-provoking and comprehensive, and that is known for its high quality, independence and objectivity.

• Our leading brand name - We have provided critical, trusted insight under the Gartner name for more than 40 years.

• Our global footprint and established customer base - We have a global presence with clients in approximately 90 countries and territories on six continents. A substantial portion of our revenue is derived from sales outside of the United States.

• Insight that creates connections - Our global community of experts, analysts and peers help provide the deep relationships that help clients stay ahead of the curve.

• Experienced management team - Our management team is comprised of research veterans and experienced industry executives with long tenure at Gartner.

• Substantial operating leverage in our business model - We can distribute our intellectual property and expertise across multiple platforms, including research and advisory subscription and membership programs, conferences and consulting engagements, to derive incremental revenue and profitability.

• Vast network of research experts and consultants - As of December 31, 2024, we had more than 2,500 research experts and 960 experienced consultants located around the world. Our research experts are located in more than 30 countries and territories, enabling us to cover vast aspects of business and technology on a global basis.

Notwithstanding these differentiating factors, we face competition from a significant number of independent providers of information products and services. We compete indirectly with consulting firms and other data and information providers, including electronic and print media companies. These indirect competitors could choose to compete directly with us in the future. In addition, we face competition from free sources of information that are available to our clients through the internet. We anticipate encountering more competition with increased adoption of AI services in the markets in which we compete. Limited barriers to entry exist in the markets in which we do business. As a result, new competitors may emerge and existing competitors may start to provide additional or complementary services. While we believe the breadth and depth of our research positions us well versus our competition, increased competition could result in loss of market share, diminished value in our products and services, reduced pricing, and increased sales and marketing expenditures.

INTELLECTUAL PROPERTY

Our success has resulted in part from proprietary methodologies, software, reusable knowledge capital and other intellectual property rights. We rely on a combination of patent, copyright, trademark, trade secret, confidentiality, non-compete and other contractual provisions to protect our intellectual property rights. We have policies related to confidentiality, ownership, quote permission, and the use and protection of Gartner’s intellectual property. We also enter into agreements with our employees and third parties as appropriate that protect our intellectual property, and we enforce these agreements if necessary. We recognize the value of our intellectual property in the marketplace and vigorously identify, create and protect it. Additionally, we actively monitor and enforce contract compliance by our end users and we assert our rights in trademark and copyright law worldwide to protect our public content.

HUMAN CAPITAL MANAGEMENT

We believe our people are our most valuable asset, enabling our sustained track record of growth. From attracting top talent through our recruitment process, to cultivating that talent with learning and development opportunities and rewards for strong performers, to supporting overall wellness with meaningful benefits and engagement, we strive to put our people first. At December 31, 2024, we had 21,044 employees globally, 10,141 of which were outside of the U.S., and the overwhelming majority of our employees were full time.

Gartner is committed to providing equal employment opportunities to all applicants and employees without regard to any legally protected status. This commitment is formalized in our global and U.S. equal employment opportunity policies. Our human capital management strategies are developed by executive management and overseen by the Compensation Committee of our Board of Directors.

Culture of Inclusion

We are committed to operating with the highest ethical standards and fostering an environment that encourages open discussions and ensures our associates and clients are treated fairly and with respect. Our vision is to build a high-performing organization with a culture of inclusion, enabling Gartner to guide the leaders who shape the world.

Currently, 36% of our Board of Directors is female, and 27% of our Board of Directors identifies as racially or ethnically diverse. As of December 31, 2024, 21% of our executive management team is female, approximately 48% of our employees worldwide are female and 25% of employees in the U.S. identified as racially or ethnically diverse. Our employees work in 39 different countries and territories.

We work to integrate best-in-class inclusive approaches into all our talent processes and practices and prioritize efforts that support our world-class talent and their unique needs. Gartner’s dedication to inclusion is driven by our passionate leaders and associates around the world.

Our eight associate-driven Employee Resource Groups (ERGs) are open to all and help foster an inclusive and supportive workplace. ERGs play an important role in enabling associate success, cultivating a culture of inclusion and creating a sense of belonging for all our associates by supporting development, recognizing life stages, inspiring associates through storytelling and driving engagement through a sense of belonging. In 2024, over 6,500 Gartner associates were members of at least one ERG.

Total Rewards

We seek to invest in meaningful, innovative and inclusive compensation and benefit programs that support physical, financial and emotional well-being of our employees. In addition to salaries, these programs (which vary by country/region) include annual bonuses, stock awards, an employee stock purchase plan, 401(k) matching, healthcare and insurance benefits, and tax savings programs, such as health and dependent care flexible spending accounts, health savings account and pretax commuter benefits. We also offer generous paid time off, paid parental leave, life and disability insurance, business travel accident insurance, charity matching, tuition assistance and on-site amenities, such as fitness centers, among others.

Additionally, we provide a number of free mental and behavioral health resources for employees and their dependents, globally. In 2024, we introduced an enhanced offering with proven on-demand self-care resources, as well as easy access to quality mental health coaches and therapists. We believe our total rewards programs facilitate associate retention and also encourage high performance.

Talent Development, Retention and Training

Gartner aims to foster a culture of lifelong learning, getting feedback and evolving. In addition to helping employees unlock their full potential through mechanisms like continuous feedback and performance appraisals, we have dedicated programs designed to develop effective leaders. We also offer rotational programs and an online learning experience platform for employees called GartnerYou. In 2024, GartnerYou offered approximately 26,000 learning resources, with over 410,000 completions globally. Since our Sales and Research & Advisory teams make up approximately 45% of total employees worldwide, we also have formal, dedicated programs to help train and onboard new hires as well as more experienced managers and leaders within Sales and Research & Advisory. Through these programs, we believe our teams develop role-specific knowledge and skills, increase productivity and improve performance.

We also strive to develop an inclusive and engaging environment that makes Gartner a vibrant, exciting place to work. We believe the greatest catalyst to engagement comes from leadership — particularly their efforts to set direction, allocate resources, and build individual and organizational capability. We embed our associate survey efforts across the enterprise so that the insight we glean can help leaders at various levels understand the opportunities for effecting organizational growth. Survey results are used for a number of enterprise-wide and business-unit-specific initiatives targeting key areas of engagement and retention, such as leadership effectiveness, career development, business process improvement, and more. While associate turnover increased slightly in 2024 as compared with the prior year, average tenure increased slightly from approximately 5.0 years in 2023 to 5.3 years in 2024.

Our Communities and the Environment

Our associates have a long history of individual and team volunteering. Gartner facilitates a charity match program. In 2024, over 20% of associates supported approximately 4,500 causes through charitable donations or volunteering. In total, more than $7.6 million was donated by Gartner and its associates and close to 19,600 hours were volunteered. We continue to embed sustainability in our operations in alignment with our near-term targets, which have been approved by the Science-Based

Targets Initiative. We also provide associates with learning opportunities, including a sustainability training module. Additionally, in 2024, over 1,000 associates were engaged in the Gartner Green Team, a voluntary, associate-driven group that enables associates to connect, learn, and drive change towards net-zero greenhouse gas emissions.
