Financial Analysis

Contingencies Legal Matters. The Company is involved in legal proceedings, claims and compliance matters arising in the ordinary course of business. The Company records a provision in its consolidated financial statements when it is determined that an unfavorable outcome in one of these matters is probable and the amount of the loss can be reasonably estimated. The Company believes that the potential liability, if any, in excess of amounts already accrued for these contingencies will not have a material effect on its financial position, cash flows or results of operations when resolved in a future period. Indemnifications. The Company has various agreements that may obligate it to indemnify the other party with respect to certain matters. Generally, these indemnification clauses are included in contracts arising in the normal course of business under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations related to matters such as title to assets sold and licensed or certain intellectual property rights. It is not possible to predict the maximum potential amount of future payments under these indemnification agreements due to the conditional nature of the Companys obligations and the unique facts of each particular agreement. Historically, payments made by the Company under these agreements have not been material. As of December 31, 2025, the Company did not have any material payment obligations under any …

Stock-Based Compensation The Company grants stock-based compensation awards as an incentive for employees and directors to contribute to the Companys 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 managements 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 mad …

Adoption of new accounting standard . The Company adopted the accounting standard described below during 2025. Income Taxes In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (ASU No. 2023-09). The amendments in this ASU are expected to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires entities to enhance income tax disclosures primarily related to the rate reconciliation and income taxes paid information. Companies will need to disaggregate the disclosure of income taxes paid (net of refunds received) by federal, state, and foreign taxes on an annual basis. Additionally, on an annual basis, companies would disclose income taxes paid disaggregated by individual jurisdiction using a quantitative threshold of 5% of total income taxes paid. Public business entities would also be required to provide, on an annual basis, rate reconciliation information by specific categories, including state and local income tax, the effect of cross-border tax laws, foreign tax effects, changes in prior year unrecognized tax benefits, and tax credits, among others. Additionally, some categories would then require disaggregation based on a quantitative threshold of 5%. The foreign tax effect category requires disaggregation by both jurisdiction and nature. The ASU also requires additional qualitative disclosures. All public entities will be required to report income tax information in accordance with the new guidance …

Revenue and Related Matters Our Business and Revenues Gartner delivers its products and services globally through three reportable segments Insights, Conferences and Consulting, as described below. Insights Insights revenues are derived from subscription contracts for insights products, representing substantially all of the segments revenue.

Goodwill and Intangible Assets Goodwill Goodwill represents the excess of the purchase price of acquired businesses over the estimated fair values of the tangible and identifiable intangible net assets acquired. Evaluations of the recoverability of goodwill are performed in accordance with FASB ASC Topic 350, which requires an annual assessment of potential goodwill impairment at the reporting unit level and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. When performing the annual assessment of the recoverability of goodwill, the Company initially performs a qualitative analysis evaluating whether any events or circumstances occurred or exist that provide evidence that it is more likely than not that the fair value of any of the Companys reporting units is less than the related carrying amount. If the Company does not believe that it is more likely than not that the fair value of any of the Companys reporting units is less than the related carrying amount, then no quantitative impairment test is performed. However, if the results of the qualitative assessment indicate that it is more likely than not that the fair value of a reporting unit is less than its respective carrying amount, then a quantitative impairment test is performed. Evaluating the recoverability of goodwill requires judgments and assumptions regarding future trends and events. As a result, both the precision and reliability of the estimates are …

The effective income tax rate was 49.1% and 21.2% for the three months ended September 30, 2025 and 2024, respectively.

The effective income tax rate was 25.6% and 21.2% for the nine months ended September 30, 2025 and 2024, respectively.
