Segments. Gartner delivers its products and services globally through three reportable segments – Business and Technology Insights (or “Insights”), Conferences, and Consulting. Note 9 — Revenue and Related Matters and Note 16 — Segment Information describe the products and services offered by each of our segments and provide additional financial information for those segments. In the second quarter of 2025, we renamed our segment previously referred to as Research to Business and Technology Insights (or “Insights”) to reflect the nature of the value we provide to clients. In the third quarter of 2025, we changed the structure of our internal organization and concluded that Gartner Digital Markets (“Digital Markets”) was an operating segment but does not meet the criteria of a reportable segment. Accordingly, Digital Markets results are now included in “Other” where segment information is provided. Digital Markets was previously included in our Insights segment. Prior periods have been recast to conform to current period presentation.

Basis of presentation. The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”), as defined in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), for financial information and with the applicable instructions of U.S. Securities and Exchange Commission (“SEC”) Regulation S-X.

The fiscal year of Gartner is the twelve-month period from January 1 through December 31. All references to 2025, 2024 and 2023 herein refer to the fiscal year unless otherwise indicated. When used in these notes, the terms “Gartner,” the “Company,” “we,” “us” or “our” refer to Gartner, Inc. and its consolidated subsidiaries.

Use of estimates. The preparation of the accompanying Consolidated Financial Statements requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of fees receivable, goodwill, intangible assets, deferred tax assets and other long-lived assets, as well as tax accruals and other liabilities. In addition, estimates are used in revenue recognition, income tax expense or benefit, performance-based compensation charges, depreciation and amortization. Management believes its use of estimates in the accompanying Consolidated Financial Statements to be reasonable.

Management continually evaluates and revises its estimates using historical experience and other factors, including the general economic environment and actions it may take in the future. Management adjusts these estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time. As a result, differences between our estimates and actual results could be material and would be reflected in the Company’s Consolidated Financial Statements in future periods.

Business acquisitions. The Company accounts for business acquisitions in accordance with the acquisition method of accounting as prescribed by FASB ASC Topic 805. The acquisition method of accounting requires the Company to record the assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, with certain exceptions. Any excess of the consideration transferred over the estimated fair value of the net assets acquired, including identifiable intangible assets, is recorded as goodwill. Under the acquisition method, the operating results of acquired companies are included in the Company’s Consolidated Financial Statements beginning on the date of acquisition. The Company completed business acquisitions in 2023 and 2022. Note 2 — Acquisition and Divestiture provides additional information regarding those business acquisitions.

projected future performance, and estimates surrounding customer turnover, as well as assumptions regarding the level of competition and the costs necessary to reproduce certain assets. Establishing the useful lives of intangible assets also requires management judgment and the evaluation of a number of factors, including the expected use of an asset, historical client retention rates, consumer awareness and trade name history, as well as any contractual provisions that could limit or extend an asset’s useful life.

•Consulting revenues are principally generated from fixed fee or time and materials engagements. Revenues from fixed fee contracts are recognized as the Company works to satisfy its performance obligations. Revenues from time and materials engagements are recognized as work is delivered and/or services are provided. Revenues related to contract optimization engagements are contingent in nature and are only recognized upon satisfaction of all conditions related to their payment.

The majority of the Company’s Insights contracts are billable upon signing, absent special terms granted on a limited basis from time to time. Insights contracts are generally non-cancellable and non-refundable, except for government contracts that may have cancellation or fiscal funding clauses. 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. Fees derived from assisting organizations in selecting the right business software for their needs are recognized when the leads are provided to vendors. Note 9 — Revenue and Related Matters provides additional information regarding the Company’s business and revenues.

Commission expense. The Company records deferred commissions upon the recognition of commission liabilities, which is generally aligned with the obtaining of a customer contract or the commencement of subsequent terms in the case of multi-year contracts. The deferred amount is amortized over a period that aligns with the transfer to the customer of the services to which the commissions relate. Note 9 — Revenue and Related Matters provides additional information regarding deferred commissions and the amortization of such costs.

Stock-based compensation expense. The Company accounts for stock-based compensation awards in accordance with FASB ASC Topics 505 and 718 and SEC Staff Accounting Bulletins No. 107 and No. 110. Stock-based compensation expense for equity awards is based on the fair value of the award on the date of grant. The Company recognizes stock-based compensation expense over the period that the related service is performed, which is generally the same as the vesting period of the underlying award. Forfeitures are recognized as they occur. A change in any of the terms or conditions of stock-based compensation awards is accounted for as a modification of the award. Incremental compensation cost is measured as the excess, if any, of the fair value of the modified award over the fair value of the original award immediately before its terms are modified, as measured on the modification date. For vested awards, the Company recognizes incremental compensation cost in the period the modification occurs. For unvested awards, the Company recognizes any incremental compensation expense at the modification date or ratably over the requisite remaining service period, as appropriate. If the fair value of the modified award is lower than the fair value of the original award immediately before modification, the minimum compensation cost the

Income taxes. The Company uses the asset and liability method of accounting for income taxes. The Company estimates its income taxes in each of the jurisdictions where it operates. This process involves estimating the Company’s current tax expense or benefit together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in the Consolidated Balance Sheets. When assessing the realizability of deferred tax assets, the Company considers if it is more likely than not that some or all of the deferred tax assets will not be realized. In making this assessment, the Company considers the availability of loss carryforwards, projected reversals of deferred tax liabilities, projected future taxable income, and ongoing prudent and feasible tax planning strategies. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained based on the technical merits of the position. Recognized tax positions are measured at the largest amount of benefit with greater than a 50% likelihood of being realized. The Company uses estimates in determining the amount of unrecognized tax benefits associated with uncertain tax positions. Significant judgment is required in evaluating tax law and measuring the benefits likely to be realized. Uncertain tax positions are periodically re-evaluated and adjusted as more information about their ultimate realization becomes available. Note 12 — Income Taxes provides additional information regarding the Company’s income taxes.

Cash and cash equivalents and restricted cash. Cash and cash equivalents includes cash and all highly liquid investments with original maturities of three months or less, which are considered to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term maturity of such instruments. Investments with maturities of more than three months are classified as marketable securities. Interest earned is recorded in Interest income in the Consolidated Statements of Operations.

U.S. GAAP requires that amounts generally described as restricted cash and restricted cash equivalents be presented with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on an entity’s statement of cash flows. Below is a table presenting the beginning-of-period and end-of-period cash amounts from the Company’s Consolidated Balance Sheets and the total cash amounts presented in the Consolidated Statements of Cash Flows (in thousands).


	December 31,
	2025		2024		2023		2022
Cash and cash equivalents	$	1,722,521	$	1,933,147	$	1,318,999	$	697,999
Restricted cash classified in (1):
Prepaid expenses and other current assets	—		—		600		—

Cash and cash equivalents and restricted cash per the Consolidated Statements of Cash Flows	$	1,722,521	$	1,933,147	$	1,319,599	$	698,599

(1)Restricted cash consisted of an escrow account established in connection with one of the Company’s business acquisitions. Generally, such cash is restricted to use due to provisions contained in the underlying acquisition agreement. During the year ended December 31, 2024, the Company paid $0.6 million of restricted cash for deferred consideration related to a 2022 acquisition.

Leases. FASB ASC Topic 842 (“ASC 842”) requires accounting for leases under a right-of-use model whereby a lessee must record a right-of-use asset and a related lease liability on its balance sheet for most of its leases. Under ASC 842, leases are classified as either operating or finance arrangements, with such classification affecting the pattern of expense recognition in an entity’s income statement. For operating leases, ASC 842 requires recognition in an entity’s income statement of a single lease cost, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. In connection with the continuing evaluation of its existing real estate portfolio, the Company reviewed certain of its right-of-use assets and related other long-lived assets for impairment under FASB ASC Topic 360 (“ASC 360”). As a result of the evaluation, the Company recognized impairment losses of $4.8 million, $10.9 million, and $20.4 million during the years ended December 31, 2025, 2024 and 2023, respectively. Note 7 — Leases provides additional information regarding the Company’s leases.

Property, equipment and leasehold improvements. Equipment, leasehold improvements and other fixed assets owned by the Company are recorded at cost less accumulated depreciation and amortization. Fixed assets, other than leasehold improvements, are depreciated using the straight-line method over the estimated useful life of the underlying asset. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the improvement or the remaining

The Company incurs costs to develop internal-use software used in its operations. Certain of those costs that meet the criteria in FASB ASC Topic 350 are capitalized and amortized over future periods. Net capitalized internal-use software development costs were $101.8 million and $122.0 million at December 31, 2025 and 2024, respectively, and are included in Computer equipment and software in the table above. Amortization expense for capitalized internal-use software development costs, which is included with Depreciation in the Consolidated Statements of Operations, totaled $68.4 million, $60.1 million and $47.8 million in 2025, 2024 and 2023, respectively.

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 Company’s 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 Company’s 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 the Company performs a quantitative impairment test. Evaluating the recoverability of goodwill requires judgments and assumptions regarding future trends and events. As a result, both the precision and reliability of management estimates are subject to uncertainty.

The Company’s most recent annual impairment test of goodwill was a quantitative analysis conducted during the quarter ended September 30, 2025 that indicated an impairment of the Company’s Digital Markets reporting unit. During the three months ended September 30, 2025, ongoing weakness in the market as well as changes in the Company’s internal organization structure prompted a revision to the long-term earnings forecast for the Digital Markets business. During the year end ended December 31, 2025, a goodwill impairment loss of $150.0 million was recognized in the Digital Markets reporting unit. The fair value of that reporting unit was estimated using a combination of the expected present value of future cash flows and market approach. Subsequent to completing the 2025 annual impairment test, no events or changes in circumstances were noted that required an interim goodwill impairment test. Note 3 — Goodwill and Intangible Assets provides additional information regarding the Company’s goodwill.

Impairment of long-lived assets. The Company’s long-lived assets primarily consist of intangible assets other than goodwill, right-of-use assets and property, equipment and leasehold improvements. The Company reviews its long-lived asset groups for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Such evaluation may be based on a number of factors, including current and projected operating results and cash flows, and changes in management’s strategic direction as well as external economic and market factors. The Company evaluates the recoverability of assets and asset groups by determining whether their carrying values can be recovered through undiscounted future operating cash flows. If events or circumstances indicate that the carrying values might not be recoverable based on undiscounted future operating cash flows, an impairment loss may be recognized. The amount of impairment is

Foreign currency exposure. The functional currency of the Company’s foreign subsidiaries is typically the local currency. All assets and liabilities of foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at average exchange rates throughout the year. The resulting translation adjustments are recorded as foreign currency translation adjustments, a component of Accumulated other comprehensive loss, net within Stockholders’ Equity on the Consolidated Balance Sheets.

Currency transaction gains or losses arising from transactions denominated in currencies other than the functional currency of a subsidiary are recognized in results of operations as part of Other income, net in the Consolidated Statements of Operations. The Company had net currency transaction gains / (losses) of $6.0 million, $(6.9) million and $(6.0) million in 2025, 2024 and 2023, respectively. The Company enters into foreign currency forward exchange contracts to mitigate the effects of adverse fluctuations in foreign currency exchange rates on certain transactions. Those contracts generally have short durations and are recorded at fair value with both realized and unrealized gains and losses recorded in Other income, net. The net (loss) / gain from foreign currency forward exchange contracts was $(3.4) million, $2.5 million and $1.9 million in 2025, 2024 and 2023, respectively. Note 13 — Derivatives and Hedging provides additional information regarding the Company’s foreign currency forward exchange contracts.

Concentrations of credit risk. Assets that may subject the Company to concentration of credit risk consist primarily of short-term, highly liquid investments classified as cash equivalents, fees receivable, contract assets, interest rate swaps and a pension reinsurance asset. The majority of the Company’s cash equivalent investments and its interest rate swap contracts are with investment grade commercial banks. Fees receivable and contract asset balances deemed to be collectible from customers have limited concentration of credit risk due to the Company’s diverse customer base and geographic dispersion. The Company’s pension reinsurance asset (see Note 15 — Employee Benefits) is maintained with a large international insurance company that was rated investment grade as of December 31, 2025 and 2024.

Gain on event cancellation insurance claims. During the year ended December 31, 2024, the Company received $300.0 million in proceeds from a settlement agreement to resolve litigation concerning the Company's event cancellation insurance for 2020 and 2021. The settlement resolved all remaining 2020 and 2021 event cancellation insurance claims. The Company received $3.1 million in proceeds during the year ended December 31, 2023 related to 2020 conference cancellation insurance claims. The Company does not record any gain on insurance claims in excess of expenses incurred until the receipt of the insurance proceeds is deemed to be realizable.

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 starting in annual periods beginning after December 15, 2024. The Company adopted ASU 2023-09 effective with the 2025 10-K and the adoption only impacted its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition. The Company has elected prospective adoption of ASU No. 2023-09.

Income Statement— In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income- Expense Disaggregation Disclosures (“ASU No. 2024-03”). The amendments in this ASU are expected to improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses (including employee compensation, depreciation and amortization) in commonly presented expense captions (such as cost of sales, SG&A and research and development). ASU 2024-03 will require a quantitative disclosure of the components of each income statement line item (e.g., cost of services and product development and selling, general and administrative expenses). It will also require entities to disclose the total amount of selling expenses, and, on an annual basis, an entity’s definition of selling expenses. The amendments are effective for annual periods with fiscal years beginning after December 15, 2026, and interim periods in fiscal years beginning after December 15, 2027. The Company expects this ASU to only impact its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Credit Losses— In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326). The amendments in this ASU introduce a practical expedient for all entities related to applying Subtopic 326-20 to current accounts receivable and current contact assets arising from transactions accounted for under Topic 606. In developing reasonable and supportable forecasts as part of estimating expected credit losses, all entities may elect a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. The amendments are expected to provide decision-useful information to investors and other financial statement users while reducing the time and effort necessary to analyze and estimate credit losses for current accounts receivable and current contract assets. The amendments will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The Company expects this ASU will not have a material impact to the Company's results of operations, cash flows, or financial condition.

Internal-use Software— In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40). The amendments in this ASU remove all references to project stages, and requires entities to start capitalizing software costs when (1) management has authorized and committed to funding the software project and (2) it is probable that the project will be completed and the software will be used to perform the function intended. The amendments are effective for annual periods with fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. The Company expects this ASU will not have a material impact to the Company's results of operations, cash flows, or financial condition.
