The CODM evaluates segment performance and allocates resources based on gross contribution. Gross contribution, as presented in the tables below, is defined as operating income or loss excluding certain Cost of services and product development expenses, Selling, general and administrative expenses, Depreciation, Amortization of intangibles, Acquisition and integration charges, Goodwill impairment and Gain from sale of divested operation. Certain bonus and fringe benefit costs included in consolidated Cost of services and product development are not allocated to segment expense. The CODM uses gross contribution to allocate resources (including financial resources and employees) for each segment primarily in the Company's annual budgeting process. The CODM then monitors budgeted versus actual results regularly to assess segment operating performance, identify business trends, and modify resource allocations as needed. The accounting policies used by the reportable segments are the same as those used by the Company. There are no intersegment revenues. The Company does not identify or allocate tangible assets, including capital expenditures, by reportable segment.

Revenue and Related MattersOur Business and RevenuesGartner delivers its products and services globally through three reportable segments – Insights, Conferences and Consulting, as described below.InsightsInsights revenues are derived from subscription contracts for insights products, representing substantially all of the segment’s revenue. The related revenues are deferred and recognized ratably over the applicable contract term (i.e., as services are provided over the contract period). The Company enters into subscription contracts for published products that generally are for twelve-month periods or longer. Historically, approximately 80% to 85% of the Company’s annual and multi-year Insights subscription contracts provide for billing of the first full service period upon signing. In subsequent years, multi-year subscription contracts are normally billed prior to the contract’s anniversary date. Other Insights subscription contracts are usually invoiced in advance, commencing with the contract signing, on (i) a quarterly, monthly or other recurring basis or (ii) in accordance with a customized invoicing schedule. Insights contracts are generally non-cancelable and non-refundable, except for government contracts that may have cancellation or fiscal funding clauses, which have not historically resulted in material cancellations. When a subscription contract is invoiced, the Company records the billable amount as a fee receivable, representing its legally enforceable right to payment. The corresponding amount is recognized as deferred revenue until the underlying services are provided and control is transferred to the customer. In certain instances, the Company may have satisfied its performance obligations and earned revenue prior to invoicing the customer. In such cases, the Company records an unbilled receivable, which represents its right to payment for services already delivered but not yet billed.ConferencesThe Company earns revenues from both the attendees and exhibitors at Gartner conferences and meetings. Attendees are generally invoiced for the full attendance fee upon their completion of an online registration form or their signing of a contract, while exhibitors typically make several individual payments commencing with the signing of a contract. Almost all of the invoiced amounts are collected in advance of the related activity, resulting in the recording of deferred revenue.

The revolving loans may be borrowed, repaid and re-borrowed until March 26, 2029, at which time all amounts borrowed must be repaid, subject to customary extension mechanics. Interest under the revolving facility accrues, at a variable rate, based on, at our option, (i) the Secured Overnight Funding Rate (“SOFR”) plus a credit spread adjustment of 0.10% or (ii) an alternate base rate (“Base Rate”) plus, in each case, an applicable margin, and is payable monthly. The applicable margin ranges between 1.125% and 1.

Stock-Based CompensationThe Company grants stock-based compensation awards as an incentive for employees and directors to contribute to the Company’s long-term success. The Company currently awards stock-settled stock appreciation rights, service-based and performance-based restricted stock units, and common stock equivalents. As of December 31, 2025, the Company had 5.2 million shares of its common stock, par value $0.0005 per share, (the “Common Stock”) available for stock-based compensation awards under its Long-Term Incentive Plan as amended and restated in June 2023 (the “Plan”). Currently, the Company issues treasury shares upon the exercise, release or settlement of stock-based compensation awards.Determining the appropriate fair value model and calculating the fair value of stock-based compensation awards requires the use of certain subjective assumptions, including the expected life of a stock-based compensation award and Common Stock price volatility. In addition, determining the appropriate periodic stock-based compensation expense requires management to estimate the likelihood of the achievement of certain performance targets. The assumptions used in calculating the fair values of stock-based compensation awards and the related periodic expense represent management’s best estimates, which involve inherent uncertainties and the application of judgment. As a result, if circumstances change and the Company deems it necessary in the future to modify the assumptions it made or to use different assumptions, or if the quantity and nature of the Company’s stock-based compensation awards changes, then the amount of expense may need to be adjusted and future stock-based compensation expense could be materially different from what has been recorded in the current year.Stock-Based Compensation ExpenseThe tables below summarize the Company’s stock-based compensation expense by award type and expense category line item during the years ended December 31 (in millions).Award type202520242023Stock appreciation rights$13.2 $13.5 $10.5 Restricted stock units (1)141.8 140.2 118.2 Common stock equivalents0.9 1.1 1.1 Total (1)$155.9 $154.8 $129.8 Expense category line item202520242023Cost of services and product development$62.8 $61.8 $53.3 Selling, general and administrative93.1 93.0 76.5 Total (1)$155.9 $154.8 $129.8 (1)Includes charges of $68.7 million, $71.4 million and $55.

LeasesThe Company’s leasing activities are primarily for facilities under cancelable and non-cancelable lease agreements expiring during 2026 and through 2038. These facilities support the Company’s executive and administrative activities, insights and consulting, sales, systems support, operations, and other functions. The Company also has leases for office equipment and other assets, which are not significant. Certain of the Company’s lease agreements include (i) renewal options to extend the lease term for up to ten years and/or (ii) options to terminate the agreement within one year. Additionally, certain of the Company’s lease agreements provide standard recurring escalations of lease payments for, among other things, increases in a lessor’s maintenance costs and taxes. Under some lease agreements, the Company may be entitled to allowances, free rent, lessor-financed tenant improvements and other incentives. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.The Company subleases certain office space that it does not intend to occupy. Such sublease arrangements expire during 2026 and through 2032 and primarily relate to facilities in Arlington, Virginia. Certain of the Company’s sublease agreements: (i) include renewal and termination options; (ii) provide for customary escalations of lease payments in the normal course of business; and (iii) grant the subtenant certain allowances, free rent, Gartner-financed tenant improvements and other incentives.Lease Accounting under ASC 842Under ASC 842, a lease is a contract or an agreement, or a part of another arrangement, between two or more parties that, at its inception, creates enforceable rights and obligations that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration.Right-of-use assets represent a right to use an underlying asset for the lease term and the related lease liability represents an obligation to make lease payments pursuant to the contractual terms of the lease agreement. Right-of-use assets and lease liabilities are initially recognized on the lease commencement date based on the present value of the lease payments over the lease term. For all of the Company’s facilities leases, the Company accounts for both lease components and nonlease components (e.g., common area maintenance charges, etc.

Cybersecurity risk management, which involves resource commitments and management attention, is overseen both as a critical component of our overall risk management program and as a standalone program. We have implemented a risk-based, cross-functional approach to identifying, preventing, and mitigating cybersecurity threats and incidents, while also implementing controls and procedures that provide for the prompt escalation of certain cybersecurity incidents. Our cybersecurity program uses a layered strategy, relying on technology and human processes to safeguard our client’s data. We embed controls within our business processes and technology development, starting with design and engineering and extending to operations. Our defense-in-depth strategy utilizes numerous layers of security controls, processes, and procedures across our information systems and networks, including but not limited to, vulnerability management, multi-factor authentication (MFA), identity access management (IAM), privileged access management (PAM), endpoint security, mobile security, application security, encryption, network security, cloud security, web security, and event monitoring and logging. Aspects of our program undergo several annual independent third-party audits and reviews, and are part of continuous bug bounty and responsible disclosure programs. We regularly review and update our cybersecurity program to address emerging threats and maintain alignment with industry best practices.We maintain a written Information Security Policy, which establishes the foundational components of our cybersecurity program and our high-level security responsibilities over all technologies, facilities and data. When engaging service providers and third-party vendors, we perform due diligence to assess whether these providers have appropriate privacy and security controls, and we generally require these providers to implement appropriate protective measures, and to use confidential information solely for the purposes of performing their services. Additionally, we have adopted a documented Incident Response Plan that applies in the event of a cybersecurity incident to provide a standardized framework for response. Our incident response process generally follows the NIST 800-61 framework and focuses on four phases: preparation; detection and analysis; containment, eradication and recovery; and post-incident remediation.
