GARTNER, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1 — Business and Basis of Presentation

Business. Gartner, Inc. (NYSE: IT) delivers actionable, objective insight that drives smarter decisions and stronger performance on an organization’s mission-critical priorities.

Segments. Gartner delivers its products and services globally through three business segments: Research, Conferences and Consulting. Revenues and other financial information for the Company’s segments are discussed in Note 6 — Segment Information.

Basis of presentation. The accompanying interim Condensed 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 270 for interim financial information and with the applicable instructions of U.S. Securities and Exchange Commission (“SEC”) Rule 10-01 of Regulation S-X on Form 10-Q, and should be read in conjunction with the consolidated financial statements and related notes of the Company in its Annual Report on Form 10-K for the year ended December 31, 2024.

The fiscal year of Gartner is the twelve-month period from January 1 through December 31. In the opinion of management, all normal recurring accruals and adjustments considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented herein have been included. The results of operations for the three months ended March 31, 2025 may not be indicative of the results of operations for the remainder of 2025 or beyond. When used in these notes, the terms “Gartner,” the “Company,” “we,” “us,” or “our” refer to Gartner, Inc. and its consolidated subsidiaries.

Principles of consolidation. The accompanying interim Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

Use of estimates. The preparation of the accompanying interim Condensed 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 estimates and actual results could be material and would be reflected in the Company’s consolidated financial statements in future periods.

Cash and cash equivalents and restricted cash. During the three months ended March 31, 2024, the Company paid $0.6 million of restricted cash for deferred consideration related to a 2022 acquisition.

Revenue recognition. Revenue is recognized in accordance with the requirements of FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”). Revenue is only recognized when all of the required criteria for revenue recognition have been met. The accompanying Condensed Consolidated Statements of Operations present revenue net of any sales or value-added taxes that we collect from customers and remit to government authorities. ASC Topic 270 requires certain disclosures in interim financial statements around the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Note 3 — Revenue and Related Matters provides additional information regarding the Company’s revenues.

Adoption of new accounting standard. The Company adopted the accounting standard described below during 2024.

8

Segment Reporting— In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements in Reportable Segment Disclosures (“ASU 2023-07”). The amendments in the ASU are expected to improve disclosures about a public entity’s reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. ASU 2023-07 requires public companies to disclose, on an annual and interim basis, significant expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit and loss. The amendments in the ASU require that a public company provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under ASC 280 in interim periods. The amendments in the ASU also require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. The amendments in the ASU, among other items, also require that a public company disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU applies to all public entities that are required to report segment information in accordance with Topic 280. All public entities are required to report segment information in accordance with the new guidance starting in annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 effective with the 2024 10-K and the adoption only impacted its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Accounting standards issued but not yet adopted. The FASB has issued accounting standards that have not yet become effective as of March 31, 2025 and may impact the Company’s Consolidated Financial Statements or related disclosures in future periods. The standards and their potential impacts are discussed below.

Income Taxes— In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 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 expects this ASU to only impact its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Income Statement— In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income- Expense Disaggregation Disclosures (“ASU 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.

Note 2 — 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 Company’s reporting units is less than the related carrying amount. If the Company does not believe that

9

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 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 subject to uncertainty.

The Company’s most recent annual impairment test of goodwill was a qualitative analysis conducted during the quarter ended September 30, 2024 that indicated no impairment. Subsequent to completing the 2024 annual impairment test, there were no events or changes in circumstances noted that required an interim impairment test.

The table below presents changes to the carrying amount of goodwill by segment during the three months ended March 31, 2025 (in thousands).

(1)Research revenues in this category are recognized in connection with performance obligations that are satisfied over time using a time-elapsed output method to measure progress. Consulting revenues in this category are recognized over time using costs incurred to date relative to total estimated costs at completion.

(2)The revenues in this category are recognized in connection with performance obligations that are satisfied at the point in time that the contractual deliverables are provided to the customer.

Performance Obligations — For customer contracts that are greater than one year in duration, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied) as of March 31, 2025 was approximately $6.1 billion. The Company expects to recognize $2.9 billion, $2.4 billion and $0.8 billion of this revenue (most of which pertains to Research) during the remainder of 2025, the year ending December 31, 2026 and thereafter, respectively.

11

The Company applies a practical expedient that is permitted under ASC Topic 606 and, accordingly, it does not disclose such performance obligation information for customer contracts that have original durations of one year or less. The Company’s performance obligations for contracts meeting this ASC Topic 606 disclosure exclusion primarily include: (i) stand-ready services under Research subscription contracts; (ii) holding conferences and meetings where attendees and exhibitors can participate; and (iii) providing customized Consulting solutions for clients under fixed fee and time and materials engagements. The remaining duration of these performance obligations is generally less than one year, which aligns with the period that the parties have enforceable rights and obligations under the affected contracts.

Customer Contract Assets and Liabilities — The timing of the recognition of revenue and the amount and timing of the Company’s billings and cash collections, including upfront customer payments, result in the recognition of both assets and liabilities on the Company’s Condensed Consolidated Balance Sheets. The table below provides information regarding certain of the Company’s balance sheet accounts that pertain to its contracts with customers (in thousands).

	March 31,		December 31,
	2025		2024
Assets:
Fees receivable, gross (1)	$	1,511,082	$	1,704,725
Contract assets recorded in Prepaid expenses and other current assets (2)	$	29,660	$	31,056
Contract liabilities:
Deferred revenues (current liability) (3)	$	2,922,518	$	2,762,927
Non-current deferred revenues recorded in Other liabilities (3)	32,319		27,389
Total contract liabilities	$	2,954,837	$	2,790,316

(1)Fees receivable represent an unconditional right to payment from the Company’s customers and include both billed and unbilled amounts.

(2)Contract assets represent recognized revenue for which the Company does not have an unconditional right to payment as of the balance sheet date because the project may be subject to a progress billing milestone or some other billing restrictions.

(3)Deferred revenues represent amounts (i) for which the Company has received an upfront customer payment or (ii) that pertain to recognized fees receivable. Both situations occur before the completion of the Company’s performance obligation(s).

The Company recognized revenue of $1.0 billion during both the three months ended March 31, 2025 and 2024, that was attributable to deferred revenues that were recorded at the beginning of each such period. Those amounts primarily consisted of Research revenues that were recognized ratably as control of the goods or services passed to the customer during the reporting periods. During each of the three months ended March 31, 2025 and 2024, the Company did not record any material impairments related to its contract assets.

Note 4 — Computation of Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in earnings. Potential shares of common stock are excluded from the computation of diluted earnings per share when their effect would be anti-dilutive.

The table below sets forth the calculation of basic and diluted income per share for the periods indicated (in thousands, except per share data).

Basic income per share	$	2.73	$	2.69
Diluted income per share	$	2.71	$	2.67

(1)Certain outstanding awards associated with stock-based compensation plans were not included in the computation of diluted income per share because the effect would have been anti-dilutive. These anti-dilutive outstanding awards associated with stock-based compensation plans was 0.2 million and de minimis for the three months ended March 31, 2025 and 2024, respectively.

Note 5 — Stock-Based Compensation

The 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 March 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 the Gartner, Inc. Long-Term Incentive Plan as amended and restated in June 2023 (the “Plan”).

The tables below summarize the Company’s stock-based compensation expense by award type and expense category line item during the periods indicated (in millions).

The Company evaluates segment performance and allocates resources based on gross contribution margin. 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 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 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 assets, including capital expenditures, by reportable segment. Accordingly, assets are not reported by segment because the information is not available by segment and is not reviewed in the evaluation of segment performance or in making decisions regarding the allocation of resources.

The tables below present information about the Company’s reportable segments for the periods indicated (in thousands).

However, the Company has an interest rate swap contract that effectively converts the floating SOFR on outstanding amounts to a fixed base rate.

(2)The Company had approximately $0.7 billion of available borrowing capacity on the 2024 Credit Agreement revolver (not including the expansion feature) as of March 31, 2025.

(3)Consists of a State of Connecticut economic development loan originated in 2019 with a 10-year maturity and bears interest at a fixed rate of 1.75%. This loan may be repaid at any time by the Company without penalty.

(4)The weighted average annual effective rate on the Company’s outstanding debt for the three months ended March 31, 2025, including the effects of its interest rate swaps discussed below, was 4.89%.

(5)Deferred financing fees are being amortized to Interest expense, net over the term of the related debt obligation.

2024 Credit Agreement

On March 26, 2024, the Company entered into a Credit Agreement (the “2024 Credit Agreement”) among the Company, as borrower, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”).

The 2024 Credit Agreement provides for a $1.0 billion senior unsecured five-year revolving facility. The facility may be increased, at the Company’s option and under certain conditions, by up to an additional $750 million in the aggregate. The facility may be used for revolving loans, and up to $75.0 million may be used for letters of credit. 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. The 2024 Credit Agreement contains certain customary restrictive loan covenants, including, among others, a financial covenant requiring a maximum leverage ratio and covenants limiting the Company’s ability to grant liens, make acquisitions, be acquired and the ability of the Company’s subsidiaries to incur indebtedness. The Company was in compliance with all financial covenants as of March 31, 2025.

On March 26, 2024, the Company borrowed $274.4 million under the 2024 Credit Agreement. The initial borrowing was used to repay the outstanding amounts under the 2020 Credit Agreement. Additional amounts borrowed under the 2024 Credit Agreement will be used for working capital needs and general corporate purposes of the Company and its subsidiaries, including the funding of acquisitions and investments, payment of capital expenditures and the repurchase of shares.

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 1.75%, depending on the lower rate determined by either the Company’s leverage ratio or the credit rating of the Company’s senior unsecured debt. At March 31, 2025, the applicable all-in margin on the revolving facility was 1.35% (including the credit spread adjustment). The commitment fee payable on the unused portion of the facility is equal to between 0.125% and 0.25% based on utilization of the facility. The Company has also agreed to pay customary letter of credit fees.

Interest Rate Swap

As of March 31, 2025, the Company had one fixed-for-floating interest rate swap contract with a notional value of $350.0 million that matures in September 2025. Under the contract, the Company pays a base fixed rate of 2.98% and in return receives a floating Term SOFR base rate on 30-day notional borrowings.

Effective June 30, 2020, the Company de-designated all of its interest rate swaps and discontinued hedge accounting. Accordingly, subsequent changes to the fair value of the interest rate swap are recorded in Other income, net. The amounts previously recorded in Accumulated other comprehensive loss are amortized into Interest expense, net over the terms of the hedged forecasted interest payments. As of March 31, 2025, $8.7 million is remaining in Accumulated other comprehensive loss, net. See Note 10 — Derivatives and Hedging for the amounts remaining in Accumulated other comprehensive loss, net of tax effect, at March 31, 2025 and December 31, 2024. See Note 11 — Fair Value Disclosures for a discussion of the fair values of Company’s interest rate swaps.

Note 8 — Equity

Share Repurchase Authorization

In 2015, the Company’s Board of Directors (the “Board”) authorized a share repurchase program to repurchase up to $1.2 billion of the Company’s common stock. The Board authorized incremental share repurchases of up to an aggregate additional $4.1 billion of the Company’s common stock from February 2021 to July 2024. As of March 31, 2025, $0.9 billion remained available under the share repurchase program. The Company may repurchase its common stock from time-to-time in amounts, at prices and in the manner that the Company deems appropriate, subject to the availability of stock, prevailing market conditions, the trading price of the stock, the Company’s financial performance and other conditions. Repurchases may be made through open market purchases (which may include repurchase plans designed to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended), accelerated share repurchases, private transactions or other transactions and will be funded by cash on hand and borrowings. Repurchases may also be made from time-to-time in connection with the settlement of the Company’s stock-based compensation awards.

The Company’s share repurchase activity is presented in the table below for the periods indicated.

See Note 7 — Debt and Note 10 — Derivatives and Hedging for information regarding the cash flow hedges.

(3)The reclassifications related to defined benefit pension plans were recorded in Other income, net.

The estimated net amount of the existing losses on the Company’s interest rate swaps that are reported in Accumulated other comprehensive loss, net at March 31, 2025 that is expected to be reclassified into earnings during the remainder of 2025 is $8.7 million.

Note 9 — Income Taxes

The provision for income taxes was $56.1 million and $49.0 million for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate was 21.0% and 18.9% for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate is higher in the current year primarily due to larger unrecognized tax benefits compared to the same period in the prior year.

The Company had gross unrecognized tax benefits of $267.2 million on March 31, 2025 and $257.5 million on December 31, 2024.

The Organization for Economic Co-operation and Development (“the OECD”) has issued various tax proposals including a two-pillar approach to global taxation (BEPS 2.0/ Pillar Two), focusing on global profit allocation and a 15% global corporate minimum tax rate. Several countries in which Gartner does business have proposed or enacted new laws to align with OECD Pillar Two proposals. The minimum tax is treated as a current cost beginning in 2024 and does not have a significant impact on the Company's effective tax rate for the current period. Significant details around the provisions are still uncertain as the OECD and participating countries continue to work on defining the underlying rules and administrative procedures. The Company will continue to monitor and reflect the impact of such legislative changes in future financial statements as appropriate.

Note 10 — Derivatives and Hedging

The Company enters into a limited number of derivative contracts to mitigate the cash flow risk associated with changes in interest rates on variable-rate debt and changes in foreign exchange rates on forecasted foreign currency transactions. The Company accounts for its outstanding derivative contracts in accordance with FASB ASC Topic 815, which requires all derivatives, including derivatives designated as accounting hedges, to be recorded on the balance sheet at fair value. The tables below provide information regarding the Company’s outstanding derivative contracts as of the dates indicated (in thousands, except for number of contracts).

(1)Effective June 30, 2020, the Company de-designated all of its interest rate swaps and discontinued hedge accounting. Accordingly, subsequent changes to fair value of the interest rate swap are recorded in Other income, net. The amounts previously recorded in Accumulated other comprehensive loss are amortized into Interest expense, net over the terms of the hedged forecasted interest payments. See Note 7 — Debt for additional information regarding the Company’s interest rate swap contract.

(2)The Company has foreign exchange transaction risk because it typically enters into transactions in the normal course of business that are denominated in foreign currencies that differ from the local functional currency. The Company enters into short-term foreign currency forward exchange contracts to mitigate the cash flow risk associated with changes in foreign currency rates on forecasted foreign currency transactions. These contracts are accounted for at fair value with realized and unrealized gains and losses recognized in Other income, net because the Company does not designate these contracts as hedges for accounting purposes. All of the outstanding foreign currency forward exchange contracts at March 31, 2025 matured before April 30, 2025.

(3)See Note 11 — Fair Value Disclosures for the determination of the fair values of these instruments.

At March 31, 2025, all of the Company’s derivative counterparties were investment grade financial institutions. The Company did not have any collateral arrangements with its derivative counterparties and none of the derivative contracts contained credit-risk related contingent features. The table below provides information regarding amounts recognized in the accompanying Condensed Consolidated Statements of Operations for derivative contracts for the periods indicated (in thousands).

	Three Months Ended
	March 31,
Amount recorded in:	2025		2024
Interest expense, net (1)	$	4,464	$	4,806
Other income, net (2)	(596)		(4,314)
Total expense, net	$	3,868	$	492

(1)Consists of interest expense from interest rate swap contracts.

19

(2)Consists of net realized and unrealized gains and losses on foreign currency forward contracts and gains and losses on de-designated interest rate swaps.

Note 11 — Fair Value Disclosures

The Company’s financial instruments include cash equivalents, fees receivable from customers, accounts payable and accrued liabilities, all of which are normally short-term in nature. The Company believes that the carrying amounts of these financial instruments reasonably approximate their fair values due to their short-term nature. The Company’s financial instruments also include its outstanding variable-rate borrowings under the 2024 Credit Agreement. The Company believes that the carrying amounts of its variable-rate borrowings reasonably approximate their fair values because the rates of interest on those borrowings reflect current market rates of interest for similar instruments with comparable maturities.

The Company enters into a limited number of derivatives transactions but does not enter into repurchase agreements, securities lending transactions or master netting arrangements. Receivables or payables that result from derivatives transactions are recorded gross in the Company’s Condensed Consolidated Balance Sheets.

FASB ASC Topic 820 provides a framework for the measurement of fair value and a valuation hierarchy based on the transparency of inputs used in the valuation of assets and liabilities. Classification within the valuation hierarchy is based on the lowest level of input that is significant to the resulting fair value measurement. The valuation hierarchy contains three levels. Level 1 measurements consist of quoted prices in active markets for identical assets or liabilities. Level 2 measurements include significant other observable inputs such as quoted prices for similar assets or liabilities in active markets; identical assets or liabilities in inactive markets; observable inputs such as interest rates and yield curves; and other market-corroborated inputs. Level 3 measurements include significant unobservable inputs such as internally-created valuation models. Generally, the Company does not utilize Level 3 valuation inputs to remeasure any of its assets or liabilities. However, Level 3 inputs may be used by the Company when certain long-lived assets, including identifiable intangible assets, goodwill, and right-of-use assets are measured at fair value on a nonrecurring basis when there are indicators of impairment. Additionally, Level 3 inputs may be used by the Company in its required annual impairment review of goodwill. Information regarding the periodic assessment of the Company’s goodwill is included in Note 2 — Goodwill and Intangible Assets. The Company does not typically transfer assets or liabilities between different levels of the valuation hierarchy.

The table below presents the fair values of certain financial assets and liabilities that are measured at fair value on a recurring basis in the Company's financial statements (in thousands).

Description	March 31, 2025		December 31, 2024

(1)The Company has a deferred compensation plan for the benefit of certain highly compensated officers, managers and other key employees. The assets consist of investments in money market funds, mutual funds and company-owned life insurance contracts, which are valued based on Level 1 or Level 2 inputs. The related deferred compensation plan liabilities are recorded at fair value, or the estimated amount needed to settle the liability, which the Company considers to be a Level 2 input.

(2)The Company enters into foreign currency forward exchange contracts to hedge the effects of adverse fluctuations in foreign currency exchange rates (see Note 10 — Derivatives and Hedging). Valuation of these contracts is based on observable foreign currency exchange rates in active markets, which the Company considers to be a Level 2 input.

(3)The Company has an interest rate swap contract that hedges the risk of variability from interest payments on its borrowings (see Note 7 — Debt). The fair value of the interest rate swap is based on mark-to-market valuations prepared by a third-party broker. This valuation is based on observable interest rates from recently executed market transactions and other observable market data, which the Company considers to be Level 2 inputs. The Company independently corroborates the reasonableness of the valuations prepared by the third-party broker by using an electronic quotation service.

The table below presents the carrying amounts (net of deferred financing costs) and fair values of financial instruments that are not recorded at fair value in the Company’s Condensed Consolidated Balance Sheets (in thousands). The estimated fair value of the financial instruments was derived from quoted market prices provided by an independent dealer, which the Company considers to be a Level 2 input.

Assets and liabilities measured at fair value on a non-recurring basis

The Company’s certain long-lived assets, including identifiable intangible assets, goodwill, right-of-use assets and other long-lived assets, are measured at fair value on a nonrecurring basis when there are indicators of impairment. The Company recorded an impairment loss during the three months ended March 31, 2024 and $0.5 million on right-of-use assets and other long-lived assets primarily related to certain office leases that the Company determined will no longer be used. The impairments were derived by comparing the fair value of the impacted assets to the carrying value of those assets as of the impairment measurement date, as required under ASC Topic 360 using Level 3 inputs. See Note 13 — Leases for additional discussion related to these impairment charges.

Note 12 — 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 Company’s obligations and the unique facts of each particular agreement. Historically, payments made by the Company under

these agreements have not been material. As of March 31, 2025, the Company did not have any material payment obligations under any such indemnification agreements.

Note 13 — Leases

21

The Company’s leasing activities are primarily for facilities under cancelable and non-cancelable lease agreements expiring during 2025 and through 2038. These facilities support our executive and administrative activities, sales, systems support, operations, and other functions. The Company also has leases for office equipment and other assets, which are not significant. Certain of these 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 2025 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.

All of the Company’s leasing and subleasing activity is recognized in Selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The table below presents the Company’s net lease cost and certain other information related to the Company’s leasing activities as of and for the periods indicated (dollars in thousands).

	Three Months Ended
	March 31,
Description:	2025		2024
Operating lease cost (1)	$	24,348	$	25,903
Lease cost (2)	5,685		5,631
Sublease income	(11,386)		(11,882)
Total lease cost, net (3) (4)	$	18,647	$	19,652
Cash paid for amounts included in the measurement of operating lease liabilities	$	28,657	$	34,049
Cash receipts from sublease arrangements	$	11,144	$	11,110
Right-of-use assets obtained in exchange for new operating lease liabilities	$	5,071	$	6,791

(1)Included in operating lease cost was $8.5 million and $9.2 million for the three months ended March 31, 2025 and 2024, respectively, for costs related to subleasing activities.

(2)These amounts are primarily variable lease and nonlease costs that are not fixed at the lease commencement date or are dependent on something other than an index or a rate.

(3)The Company did not capitalize any operating lease costs during any of the periods presented.

(4)Amount excludes impairment charges on lease related assets, as discussed below.

The table below indicates where the discounted operating lease payments from the above table are classified in the accompanying Condensed Consolidated Balance Sheets (in thousands).

	March 31,		December 31,
Description:	2025		2024
Accounts payable and accrued liabilities	$	98,477	$	100,312
Operating lease liabilities	324,549		339,779
Total operating lease liabilities included in the Condensed Consolidated Balance Sheets	$	423,026	$	440,091

As a result and in consideration of the changing nature of the Company’s use of office space, the Company continues to evaluate its existing real estate lease portfolio. In connection with this evaluation, the Company reviewed certain of its right-of-use assets and related other long-lived assets for impairment under ASC 360. As a result of the evaluation, the Company recognized an impairment loss during the three months ended March 31, 2024 of $0.5 million which is included as a component of Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. The impairment losses recorded include $0.4 million related to right-of-use assets and $0.1 million related to other long-lived assets, primarily leasehold improvements, for the three months ended March 31, 2024.

The fair values for the asset groups relating to the impaired long-lived assets were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair values include the

22

expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflect the level of risk associated with receiving future cash flows.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The purpose of this Management’s Discussion and Analysis (“MD&A”) is to facilitate an understanding of significant factors influencing the quarterly operating results, financial condition and cash flows of Gartner, Inc. Additionally, the MD&A conveys our expectations of the potential impact of known trends, events or uncertainties that may impact future results. You should read this discussion in conjunction with our Condensed Consolidated Financial Statements and related notes included in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”). Historical results and percentage relationships are not necessarily indicative of operating results for future periods. References to “Gartner,” the “Company,” “we,” “our” and “us” in this MD&A are to Gartner, Inc. and its consolidated subsidiaries.

FORWARD-LOOKING STATEMENTS

In addition to historical information, this Quarterly Report on Form 10-Q contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are any statements other than statements of historical fact, including statements regarding our expectations, beliefs, hopes, intentions, projections or strategies regarding the future. In some cases, forward-looking statements can be identified by the use of words such as “may,” “will,” “expect,” “should,” “could,” “believe,” “plan,” “anticipate,” “estimate,” “predict,” “potential,” “continue” or other words of similar meaning.

We operate in a very competitive and rapidly changing environment that involves numerous known and unknown risks and uncertainties, some of which are beyond our control. Although we believe that the expectations reflected in any of our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements. Our future quarterly and annual revenues, operating income, results of operations and cash flows, as well as any forward-looking statement, are subject to change and to inherent risks and uncertainties, such as those disclosed or incorporated by reference in our filings with the Securities and Exchange Commission. Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in our forward-looking statements include, among others, the following: the impact of global economic and geopolitical conditions, including inflation, and recession; uncertain effects, both direct and indirect, of changes and volatility in tariffs and trade policies; risks associated with the creditworthiness, budget cuts, priorities and shutdown of governments and agencies; our ability to carry out our strategic initiatives and manage associated costs; the timing of conferences and meetings, in particular our Gartner Symposium/Xpo series that normally occurs during the fourth quarter; our ability to achieve and effectively manage growth, including our ability to integrate our acquisitions and consummate and integrate future acquisitions; our ability to pay our debt obligations; our ability to maintain and expand our products and services; our ability to expand or retain our customer base; our ability to grow or sustain revenue from individual customers; our ability to attract and retain a professional staff of research analysts and consultants as well as experienced sales personnel upon whom we are dependent, especially in light of labor competition; our ability to achieve continued customer renewals and achieve new contract value, backlog and deferred revenue growth in light of competitive pressures; our ability to successfully compete with existing competitors and potential new competitors; our ability to enforce and protect our intellectual property rights; our ability to keep pace with technological developments in artificial intelligence (“AI”) and comply with evolving AI regulations; additional risks associated with international operations, including foreign currency fluctuations; the impact on our business resulting from changes in international conditions, including those resulting from the conflict in the Middle East, the war in Ukraine and current and future sanctions imposed by governments or other authorities; the impact of restructuring and other charges on our businesses and operations; cybersecurity incidents or other disruptions to our information systems; our ability to meet sustainability commitments and comply with applicable regulatory requirements, as well as potential reactions by customers to these commitments; the impact of changes in tax policy (including global minimum tax legislation) and heightened scrutiny from various taxing authorities globally; changes to laws and regulations; and other risks and uncertainties. The potential fluctuations in our operating income could cause period-to-period comparisons of operating results not to be meaningful and could provide an unreliable indication of future operating results. A description of the risk factors associated with our business is included under “Risk Factors” in Item 1A. of the 2024 Form 10-K, which is incorporated herein by reference.

Forward-looking statements are subject to risks, estimates and uncertainties that could cause actual results to differ materially from those discussed in, or implied by, the forward-looking statements. Factors that might cause such a difference include, but are not limited to, those listed above or described under “Risk Factors” in Item 1A of the 2024 Form 10-K. Readers should not place undue reliance on these forward-looking statements, which reflect management’s opinion only as of the date on which they were made. Forward-looking statements in this Quarterly Report on Form 10-Q speak only as of the date hereof, and forward-looking statements in documents attached that are incorporated by reference speak only as of the date of those documents. Except as required by law, we disclaim any obligation to review or update these forward-looking statements to reflect events or circumstances as they occur.

Recent Developments

Our Research contract value with the US federal government was approximately $225.0 million at March 31, 2025, as compared to approximately $275.0 million at December 31, 2024. Nearly all of our US federal contracts will come to term during 2025, with about 40% having transacted in the first quarter of 2025, the largest quarter of this calendar year. Slightly less than half of the US federal government contract value that was eligible for renewal in the first quarter of 2025 was retained. In addition to the non-renewals, we received notices of termination-for-convenience from various US government agencies for approximately $30.0 million of contracts in the first quarter of 2025. These contracts are non-refundable, with nearly all scheduled to expire during 2025.

As the current geopolitical environment remains unpredictable, we continue to monitor and evaluate the impact, both direct and indirect, of government actions that could adversely impact our business operations and financial performance.

BUSINESS MEASUREMENTS

We believe that the following business measurements are important performance indicators for our business segments:

25

BUSINESS SEGMENT	BUSINESS MEASUREMENT
Research	Contract value represents the dollar value attributable to all of our subscription-related contracts. It is calculated as the annualized value of all contracts in effect at a specific point in time, without regard to the duration of the contract. Contract value primarily includes Research deliverables for which revenue is recognized on a ratable basis, as well as other deliverables (primarily Conferences tickets) for which revenue is recognized when the deliverable is utilized. Comparing contract value year-over-year not only measures the short-term growth of our business, but also signals the long-term health of our Research subscription business since it measures revenue that is highly likely to recur over a multi-year period. Our contract value consists of Global Technology Sales contract value, which includes sales to users and providers of technology, and Global Business Sales contract value, which includes sales to all other functional leaders.
	Client retention rate represents a measure of client satisfaction and renewed business relationships at a specific point in time. Client retention is calculated on a percentage basis by dividing our current clients, who were also clients a year ago, by all clients from a year ago. Client retention is calculated at an enterprise level, which represents a single company or customer.
	Wallet retention rate represents a measure of the amount of contract value we have retained with clients over a twelve-month period. Wallet retention is calculated on a percentage basis by dividing the contract value of our current clients, who were also clients a year ago, by the contract value from a year ago, excluding the impact of foreign currency exchange. When wallet retention exceeds client retention, it is an indication of retention of higher-spending clients, or increased spending by retained clients, or both. Wallet retention is calculated at an enterprise level, which represents a single company or customer.
Conferences	Number of destination conferences represents the total number of hosted in-person conferences completed during the period. Single day, local meetings are excluded.
	Number of destination conferences attendees represents the total number of people who attend in-person conferences. Single day, local meetings are excluded.
Consulting	Consulting backlog represents future revenue to be derived from in-process consulting and benchmark analytics engagements.
	Utilization rate represents a measure of productivity of our consultants. Utilization rates are calculated for billable headcount on a percentage basis by dividing total hours billed by total hours available to bill.

26

In addition to GAAP results, we provide foreign currency neutral dollar amounts and percentages for our revenues, certain expenses, contract values and other metrics. These foreign currency neutral dollar amounts and percentages eliminate the effects of exchange rate fluctuations and thus provide a more accurate and meaningful trend in the underlying business performance being measured. We calculate foreign currency neutral dollar amounts by converting the underlying amounts in local currency for different periods into U.S. dollars by applying the same foreign exchange rates to all periods presented.

Total revenues for the three months ended March 31, 2025 were $1.5 billion, an increase of $61.2 million, or 4% compared to the same period in 2024 on a reported basis and 6% excluding the foreign currency impact. Refer to the section of this MD&A below entitled “Segment Results” for a discussion of revenues and results by segment.

Cost of services and product development was $475.0 million during the three months ended March 31, 2025, an increase of $15.6 million compared to the same period in 2024, or 3% on a reported basis and 4% excluding the foreign currency impact. The increase in Cost of services and product development was primarily due to a $19.0 million increase in personnel expenses associated with headcount increases. Cost of services and product development as a percent of revenues was 31% for each of the three months ended March 31, 2025 and 2024.

Selling, general and administrative (“SG&A”) expense was $730.3 million during the three months ended March 31, 2025, an increase of $40.5 million compared to the same period in 2024, or 6% and on a reported basis and 7% excluding the foreign currency impact. The increase in SG&A expense during the three months ended March 31, 2025 was primarily a result of a $40.8 million increase in personnel expenses due to increased headcount. The number of quota-bearing sales associates in Global Technology Sales increased by 3% to 3,707 and in Global Business Sales, increased by 9% to 1,331 compared to March 31, 2024. On a combined basis, the total number of quota-bearing sales associates increased by 4% when compared to March 31, 2024. SG&A expense as a percent of revenues was 48% and 47% during the three months ended March 31, 2025 and 2024, respectively.

Depreciation increased by 10% during the three months ended March 31, 2025, compared to the same periods in 2024. The increase for the three months ended March 31, 2025 was primarily due to increased software additions during the last twelve months.

Amortization of intangibles decreased by 5% during the three months ended March 31, 2025, compared to the same periods in 2024, due to certain intangible assets becoming fully amortized in 2024.

28

Acquisition and integration charges decreased by $0.5 million during the three months ended March 31, 2025, respectively, compared to the same periods in 2024.

Operating income was $278.0 million and $273.9 million during the three months ended March 31, 2025 and 2024, respectively. The slight increase in operating income for the three months ended March 31, 2025 as compared to the prior year period was primarily due to increased revenues, partially offset by increases in cost of services and product development and selling, general and administrative expenses.

Interest expense, net decreased by $5.8 million during the three months ended March 31, 2025, compared to the same period in 2024. The decrease for the three months ended March 31, 2025 was due to increased interest income, primarily as a result of higher cash balances than the prior year.

Other income, net for the periods presented herein included the net impact of foreign currency gains and losses from our hedging activities. Other income, net for the three months ended March 31, 2025 and 2024 also included gains of $0.2 million and $4.5 million, respectively, on de-designated interest rate swaps.

The provision for income taxes was $56.1 million and $49.0 million for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate was 21.0% and 18.9% for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate is higher in the current year primarily due to larger unrecognized tax benefits compared to the same period in the prior year.

Net income for the three months ended March 31, 2025 and 2024 was $210.9 million and $210.5 million, respectively. Our diluted net income per share during the three months ended March 31, 2025 increased by $0.04. The slight increase in net income during the three months ended March 31, 2025 was primarily due to an increase in revenues and lower interest expense, net, partially offset by increases in operating expenses and the provision for income taxes.

SEGMENT RESULTS

We evaluate reportable segment performance and allocate resources based on gross contribution margin. Gross contribution is defined as operating income or loss excluding certain Cost of services and product development expenses, SG&A expenses, Depreciation, Amortization of intangibles, Acquisition and integration charges and Gain from sale of divested operation. Gross contribution margin is defined as gross contribution as a percent of revenues.

(2)Global Technology Sales includes sales to users and providers of technology. Global Business Sales includes sales to all other functional leaders.

(3)Contract values are on a foreign currency neutral basis. Contract values as of March 31, 2024 have been calculated using the same foreign currency rates as 2025.

Research revenues increased by $53.7 million during the three months ended March 31, 2025 compared to the same period in 2024, or 4% on a reported basis and 6% excluding the foreign currency impact. The increase in revenues during 2025 was primarily due to Research contract value growth in 2024. The segment gross contribution margin was 74% for both the three months ended March 31, 2025 and 2024.

Contract value increased to $5.1 billion at March 31, 2025, or 7% compared to March 31, 2024 excluding the foreign currency impact. The majority of industry sectors grew high single-digit rates. Growth was led by the energy, manufacturing and healthcare sectors, with public sector lagging in the low single digits. Global Technology Sales (“GTS”) contract value increased by 6% at March 31, 2025 when compared to March 31, 2024. The increase in GTS contract value was primarily due to new business from existing clients. GTS contract value increased by mid single-digit rates or faster for all enterprise sizes except small enterprises and public sector and nearly all industry sectors. Global Business Sales (“GBS”) contract value increased by 11% year-over-year, also primarily driven by new business from existing clients. The majority of our GBS practices achieved double-digit growth rates, with the majority of enterprise sizes and sectors growing double-digits year-over-year as well.

GTS client retention was 84% and 83% as of March 31, 2025 and 2024, respectively while wallet retention was 101% for both periods. GBS client retention was 87% as of both March 31, 2025 and 2024, while wallet retention was 105% and 107%, respectively. The decrease in GBS wallet retention was largely due to lower levels of spending by existing clients compared to the same period in 2024.

Conferences revenues increased by $2.5 million during the three months ended March 31, 2025 compared to the same period in 2024, or 4% on a reported basis and 5% excluding the foreign currency impact. The increase in revenues for the three months ended March 31, 2025 was primarily due to increased exhibitor revenue compared to the same period in 2024. We held 10 and 12 in-person destination conferences during the three months ended March 31, 2025 and 2024, respectively. Gross contribution increased to $27.4 million during the three months ended March 31, 2025 compared to $23.3 million in the same period last year. The increase in gross contribution during the three months ended March 31, 2025 was primarily the result of the increase in revenues, as well as a decrease in conference-related expenses as a result of two destination conferences moving from the first quarter to the second quarter in 2025.

(2)Backlog is on a foreign currency neutral basis. Backlog as of March 31, 2024 has been calculated using the same foreign currency rates as 2025.

Consulting revenues increased by 4% during the three months ended March 31, 2025 compared to the same period in 2024 on a reported basis and 5% excluding the foreign currency impact, with a decrease in labor-based consulting revenue of 4% and an increase in contract optimization revenue of 36%, each on a reported basis. Contract optimization revenue may vary significantly and, as such, revenues for the first quarter of 2025 may not be indicative of results for the remainder of 2025 or beyond. The segment gross contribution margin was 38% and 40% for the three months ended March 31, 2025 and 2024, respectively. The decrease in gross contribution margin for the three months ended March 31, 2025 was primarily due to an increase in personnel expenses due to higher headcount.

Backlog increased by $29.8 million, or 16%, from March 31, 2024 to March 31, 2025, excluding the foreign currency impact.

LIQUIDITY AND CAPITAL RESOURCES

We finance our operations through cash generated from our operating activities and, to a lesser extent, borrowings. Note 7 — Debt in the Notes to Condensed Consolidated Financial Statements provides additional information regarding the Company’s outstanding debt obligations. At March 31, 2025, we had $2.1 billion of cash and cash equivalents and approximately $0.7 billion of available borrowing capacity on the revolving credit facility under our 2024 Credit Agreement. We believe that the Company has adequate liquidity to meet its currently anticipated needs for both the next twelve months and the foreseeable future.

We have historically generated significant cash flows from our operating activities, benefiting from the favorable working capital dynamics of our subscription-based business model in our Research segment, which is our largest business segment and historically has constituted a significant portion of our total revenues. The majority of our Research customer contracts are paid in advance and, combined with a strong customer retention rate and high incremental margins, our subscription-based business model has resulted in continuously strong operating cash flow. Cash flow generation has also benefited from our ongoing efforts to improve the operating efficiencies of our businesses as well as a focus on the optimal management of our working capital as we increase sales.

During the fourth quarter of 2024, we entered into an amended lease agreement to significantly reduce the square footage and reduce future lease payments at one of our leased locations. We made an installment payment of $24.0 million during the fourth quarter of 2024, and will make an equal installment payment during the second quarter of 2025 in consideration for the lease amendment.

Our cash and cash equivalents are held in numerous locations throughout the world with 41% held outside the U.S. at March 31, 2025. We intend to distribute a portion of the accumulated undistributed earnings of non-U.S. subsidiaries as of March 31, 2025 in conjunction with global restructuring activity and have recorded a modest tax expense for the anticipated impact of such distribution. We continue to assert our intention to reinvest substantially all remaining accumulated undistributed foreign earnings, except in instances where repatriation would result in minimal additional tax..

The table below summarizes the changes in our cash balances for the periods indicated (in thousands).

	Three Months Ended March 31, 2025		Three Months Ended March 31, 2024		Increase (Decrease)
Cash provided by operating activities	$	313,512	$	188,836	$	124,676
Cash used in investing activities	(25,569)		(24,660)		(909)
Cash used in financing activities	(152,936)		(219,681)		66,745
Net increase (decrease) in cash and cash equivalents and restricted cash	135,007		(55,505)		190,512

Ending cash and cash equivalents	$	2,091,048	$	1,236,401	$	854,647

Operating

Cash provided by operating activities was $313.5 million and $188.8 million during the three months ended March 31, 2025 and 2024, respectively. The year-over-year increase was primarily due to the improved timing of collections.

Investing

Cash used in investing activities was $25.6 million and $24.7 million during the three months ended March 31, 2025 and 2024, respectively. The increase from 2024 to 2025 was primarily the result of higher leasehold improvements expenditures.

Financing

Cash used in financing activities was $152.9 million and $219.7 million during the three months ended March 31, 2025 and 2024, respectively. We used $162.7 million and $225.1 million of cash for share repurchases during the three months ended

33

March 31, 2025 and 2024, respectively. In March 2024, the Company borrowed $274.4 million under the 2024 Credit Agreement. The initial borrowing was used to repay the outstanding amounts under the 2020 Credit Agreement.

Debt

As of March 31, 2025, the Company had $2.5 billion of principal amount of debt outstanding. Note 7 — Debt in the Notes to Condensed Consolidated Financial Statements provides additional information regarding the Company’s outstanding debt obligations. From time to time, the Company may seek to retire or repurchase its outstanding debt through various methods including open market repurchases, negotiated block transactions, or otherwise, all or some of which may be effected through Rule 10b5-1 plans. Such transactions, if any, depend on prevailing market conditions, our liquidity and capital requirements, contractual restrictions, and other factors, and may involve material amounts.

OFF BALANCE SHEET ARRANGEMENTS

From January 1, 2025 through March 31, 2025, the Company has not entered into any material off-balance sheet arrangements or transactions with unconsolidated entities or other persons.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

As of March 31, 2025, the Company had $2.5 billion in total debt principal outstanding. Note 7 — Debt in the Notes to Condensed Consolidated Financial Statements provides additional information regarding the Company’s outstanding debt obligations.

Approximately $274.4 million of the Company’s total debt outstanding as of March 31, 2025 was based on a floating base rate of interest, which potentially exposes the Company to increases in interest rates. However, we reduce our overall exposure to interest rate increases through our interest rate swap contract, which effectively converts the floating base interest rates on all of our variable rate borrowings to fixed rates.

FOREIGN CURRENCY RISK

A significant portion of our revenues are typically derived from sales outside of the United States. Among the major foreign currencies in which we conduct business are the Euro, the British Pound, the Japanese Yen, the Australian dollar and the Canadian dollar. The reporting currency of our Condensed Consolidated Financial Statements is the U.S. dollar. As the values of the foreign currencies in which we operate fluctuate over time relative to the U.S. dollar, the Company is exposed to both foreign currency translation and transaction risk.

Translation risk arises as our foreign currency assets and liabilities are translated into U.S. dollars because the functional currencies of our foreign operations are generally denominated in the local currency. Adjustments resulting from the translation of these assets and liabilities are deferred and recorded as a component of stockholders’ equity. A measure of the potential impact of foreign currency translation can be determined through a sensitivity analysis of our cash and cash equivalents. At March 31, 2025, we had $2.1 billion of cash and cash equivalents, with a substantial portion denominated in foreign currencies. If the exchange rates of the foreign currencies we hold all changed in comparison to the U.S. dollar by 10%, the amount of cash and cash equivalents we would have reported on March 31, 2025 could have increased or decreased by approximately $79.9 million. The translation of our foreign currency revenues and expenses historically has not had a material impact on our consolidated earnings because movements in and among the major currencies in which we operate tend to impact our revenues and expenses fairly equally. However, our earnings could be impacted during periods of significant exchange rate volatility, or when some or all of the major currencies in which we operate move in the same direction against the U.S. dollar.

Transaction risk arises when we enter into a transaction that is denominated in a currency that may differ from the local functional currency. As these transactions are translated into the local functional currency, a gain or loss may result, which is recorded in current period earnings. We typically enter into foreign currency forward exchange contracts to mitigate the effects of some of this foreign currency transaction risk. Our outstanding foreign currency forward exchange contracts as of March 31, 2025 had an immaterial net unrealized loss.

CREDIT RISK

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of short-term, highly liquid investments classified as cash equivalents, fees receivable, interest rate swap contracts and foreign currency forward exchange contracts. The majority of the Company’s cash and cash equivalents, interest rate swap contracts and foreign currency forward exchange contracts are with large investment grade commercial banks. Fees receivable balances deemed to be collectible from customers have limited concentration of credit risk due to our diverse customer base and geographic dispersion.

35

ITEM 4. CONTROLS AND PROCEDURES

We have established disclosure controls and procedures that are designed to ensure that the information we are required to disclose in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and such information is accumulated and communicated to our executive management team, including our chief executive officer and our chief financial officer, to allow timely decisions regarding required disclosure.

Management conducted an evaluation, as of March 31, 2025, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, under the supervision and with the participation of our chief executive officer and chief financial officer. Based upon that evaluation, our chief executive officer and chief financial officer have concluded that, as of March 31, 2025, the Company’s disclosure controls and procedures were effective.

There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

36

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are involved in legal and administrative proceedings and litigation arising in the ordinary course of business. We believe that the potential liability, if any, in excess of amounts already accrued from all proceedings, claims and litigation will not have a material effect on our financial position, cash flows or results of operations when resolved in a future period.

ITEM 1A. RISK FACTORS

There were no material changes to the risk factors disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

There were no unregistered sales of equity securities during the period covered by this report.

Issuer Purchases of Equity Securities

In May 2015, the Company’s Board of Directors (the “Board”) authorized a share repurchase program to repurchase up to $1.2 billion of the Company’s common stock. The Board authorized incremental share repurchases of up to an aggregate additional $4.1 billion of the Company’s common stock from February 2021 to July 2024. The Company may repurchase its common stock from time-to-time in amounts, at prices and in the manner that the Company deems appropriate, subject to the availability of stock, prevailing market conditions, the trading price of the stock, the Company’s financial performance and other conditions. Repurchases may be made through open market purchases (which may include repurchase plans designed to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended), accelerated share repurchases, private transactions or other transactions and will be funded by cash on hand and borrowings. Repurchases may also be made from time-to-time in connection with the settlement of the Company’s stock-based compensation awards. The table below summarizes the repurchases of our common stock during the three months ended March 31, 2025.

Period	Total Number of Shares Purchased (#)	Average Price Paid Per Share ($)		Total Number of Shares Purchased Under Announced Programs (#)	Maximum Approximate Dollar Value of Shares That May Yet Be Purchased Under the Plans or Programs (in thousands)
January 1, 2025 to January 31, 2025	163,247	$	490.13	163,201	$	873,855

March 1, 2025 to March 31, 2025	269	477.73		—	$	873,855
Total for the quarter (1)	300,745	$	507.65	163,201

(1)The repurchased shares during the three months ended March 31, 2025 included 137,544 shares purchased for the settlement of stock-based compensation awards and 163,201 shares purchased in the open market. Amounts presented exclude the excise tax accrual.

ITEM 5. OTHER INFORMATION

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business and Basis of Presentation

Business and Basis of Presentation

Business. Gartner, Inc. (NYSE: IT) delivers actionable, objective insight that drives smarter decisions and stronger performance on an organization’s mission-critical priorities.

Segments. Gartner delivers its products and services globally through three business segments: Research, Conferences and Consulting. Revenues and other financial information for the Company’s segments are discussed in Note 6 — Segment Information.

Basis of presentation. The accompanying interim Condensed 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 270 for interim financial information and with the applicable instructions of U.S. Securities and Exchange Commission (“SEC”) Rule 10-01 of Regulation S-X on Form 10-Q, and should be read in conjunction with the consolidated financial statements and related notes of the Company in its Annual Report on Form 10-K for the year ended December 31, 2024.

The fiscal year of Gartner is the twelve-month period from January 1 through December 31. In the opinion of management, all normal recurring accruals and adjustments considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented herein have been included. The results of operations for the three months ended March 31, 2025 may not be indicative of the results of operations for the remainder of 2025 or beyond. When used in these notes, the terms “Gartner,” the “Company,” “we,” “us,” or “our” refer to Gartner, Inc. and its consolidated subsidiaries.

Principles of consolidation. The accompanying interim Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

Use of estimates. The preparation of the accompanying interim Condensed 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 estimates and actual results could be material and would be reflected in the Company’s consolidated financial statements in future periods.

Cash and cash equivalents and restricted cash. During the three months ended March 31, 2024, the Company paid $0.6 million of restricted cash for deferred consideration related to a 2022 acquisition.

Revenue recognition. Revenue is recognized in accordance with the requirements of FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”). Revenue is only recognized when all of the required criteria for revenue recognition have been met. The accompanying Condensed Consolidated Statements of Operations present revenue net of any sales or value-added taxes that we collect from customers and remit to government authorities. ASC Topic 270 requires certain disclosures in interim financial statements around the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Note 3 — Revenue and Related Matters provides additional information regarding the Company’s revenues.

Adoption of new accounting standard. The Company adopted the accounting standard described below during 2024.

Segment Reporting— In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements in Reportable Segment Disclosures (“ASU 2023-07”). The amendments in the ASU are expected to improve disclosures about a public entity’s reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. ASU 2023-07 requires public companies to disclose, on an annual and interim basis, significant expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit and loss. The amendments in the ASU require that a public company provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under ASC 280 in interim periods. The amendments in the ASU also require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. The amendments in the ASU, among other items, also require that a public company disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU applies to all public entities that are required to report segment information in accordance with Topic 280. All public entities are required to report segment information in accordance with the new guidance starting in annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 effective with the 2024 10-K and the adoption only impacted its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Accounting standards issued but not yet adopted. The FASB has issued accounting standards that have not yet become effective as of March 31, 2025 and may impact the Company’s Consolidated Financial Statements or related disclosures in future periods. The standards and their potential impacts are discussed below.

Income Taxes— In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 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 expects this ASU to only impact its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Income Statement— In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income- Expense Disaggregation Disclosures (“ASU 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.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

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 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 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 subject to uncertainty.

The Company’s most recent annual impairment test of goodwill was a qualitative analysis conducted during the quarter ended September 30, 2024 that indicated no impairment. Subsequent to completing the 2024 annual impairment test, there were no events or changes in circumstances noted that required an interim impairment test.

The table below presents changes to the carrying amount of goodwill by segment during the three months ended March 31, 2025 (in thousands).

Total revenues	$	1,268,172	$	70,069	$	134,685	$	1,472,926

(1)Research revenues in this category are recognized in connection with performance obligations that are satisfied over time using a time-elapsed output method to measure progress. Consulting revenues in this category are recognized over time using costs incurred to date relative to total estimated costs at completion.

(2)The revenues in this category are recognized in connection with performance obligations that are satisfied at the point in time that the contractual deliverables are provided to the customer.

Performance Obligations — For customer contracts that are greater than one year in duration, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied) as of March 31, 2025 was approximately $6.1 billion. The Company expects to recognize $2.9 billion, $2.4 billion and $0.8 billion of this revenue (most of which pertains to Research) during the remainder of 2025, the year ending December 31, 2026 and thereafter, respectively.

The Company applies a practical expedient that is permitted under ASC Topic 606 and, accordingly, it does not disclose such performance obligation information for customer contracts that have original durations of one year or less. The Company’s performance obligations for contracts meeting this ASC Topic 606 disclosure exclusion primarily include: (i) stand-ready services under Research subscription contracts; (ii) holding conferences and meetings where attendees and exhibitors can participate; and (iii) providing customized Consulting solutions for clients under fixed fee and time and materials engagements. The remaining duration of these performance obligations is generally less than one year, which aligns with the period that the parties have enforceable rights and obligations under the affected contracts.

Customer Contract Assets and Liabilities — The timing of the recognition of revenue and the amount and timing of the Company’s billings and cash collections, including upfront customer payments, result in the recognition of both assets and liabilities on the Company’s Condensed Consolidated Balance Sheets. The table below provides information regarding certain of the Company’s balance sheet accounts that pertain to its contracts with customers (in thousands).

	March 31,		December 31,
	2025		2024
Assets:
Fees receivable, gross (1)	$	1,511,082	$	1,704,725
Contract assets recorded in Prepaid expenses and other current assets (2)	$	29,660	$	31,056
Contract liabilities:
Deferred revenues (current liability) (3)	$	2,922,518	$	2,762,927
Non-current deferred revenues recorded in Other liabilities (3)	32,319		27,389
Total contract liabilities	$	2,954,837	$	2,790,316

(1)Fees receivable represent an unconditional right to payment from the Company’s customers and include both billed and unbilled amounts.

(2)Contract assets represent recognized revenue for which the Company does not have an unconditional right to payment as of the balance sheet date because the project may be subject to a progress billing milestone or some other billing restrictions.

(3)Deferred revenues represent amounts (i) for which the Company has received an upfront customer payment or (ii) that pertain to recognized fees receivable. Both situations occur before the completion of the Company’s performance obligation(s).

The Company recognized revenue of $1.0 billion during both the three months ended March 31, 2025 and 2024, that was attributable to deferred revenues that were recorded at the beginning of each such period. Those amounts primarily consisted of Research revenues that were recognized ratably as control of the goods or services passed to the customer during the reporting periods. During each of the three months ended March 31, 2025 and 2024, the Company did not record any material impairments related to its contract assets.

Earnings Per Share [Abstract]

Computation of Earnings Per Share

Computation of Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in earnings. Potential shares of common stock are excluded from the computation of diluted earnings per share when their effect would be anti-dilutive.

The table below sets forth the calculation of basic and diluted income per share for the periods indicated (in thousands, except per share data).

The Company evaluates segment performance and allocates resources based on gross contribution margin. 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 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 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 assets, including capital expenditures, by reportable segment. Accordingly, assets are not reported by segment because the information is not available by segment and is not reviewed in the evaluation of segment performance or in making decisions regarding the allocation of resources.

The tables below present information about the Company’s reportable segments for the periods indicated (in thousands).

(1)The contractual annualized interest rate as of March 31, 2025 on the 2024 Credit Agreement was 5.725%, which consisted of Term Secured Overnight Financing Rate (“SOFR”) of 4.375% plus a margin of 1.350%. However, the Company has an interest rate swap contract that effectively converts the floating SOFR on outstanding amounts to a fixed base rate.

(2)The Company had approximately $0.7 billion of available borrowing capacity on the 2024 Credit Agreement revolver (not including the expansion feature) as of March 31, 2025.

(3)Consists of a State of Connecticut economic development loan originated in 2019 with a 10-year maturity and bears interest at a fixed rate of 1.75%. This loan may be repaid at any time by the Company without penalty.

(4)The weighted average annual effective rate on the Company’s outstanding debt for the three months ended March 31, 2025, including the effects of its interest rate swaps discussed below, was 4.89%.

(5)Deferred financing fees are being amortized to Interest expense, net over the term of the related debt obligation.

2024 Credit Agreement

On March 26, 2024, the Company entered into a Credit Agreement (the “2024 Credit Agreement”) among the Company, as borrower, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”).

The 2024 Credit Agreement provides for a $1.0 billion senior unsecured five-year revolving facility. The facility may be increased, at the Company’s option and under certain conditions, by up to an additional $750 million in the aggregate. The facility may be used for revolving loans, and up to $75.0 million may be used for letters of credit. 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. The 2024 Credit Agreement contains certain customary restrictive loan covenants, including, among others, a financial covenant requiring a maximum leverage ratio and covenants limiting the Company’s ability to grant liens, make acquisitions, be acquired and the ability of the Company’s subsidiaries to incur indebtedness. The Company was in compliance with all financial covenants as of March 31, 2025.

On March 26, 2024, the Company borrowed $274.4 million under the 2024 Credit Agreement. The initial borrowing was used to repay the outstanding amounts under the 2020 Credit Agreement. Additional amounts borrowed under the 2024 Credit Agreement will be used for working capital needs and general corporate purposes of the Company and its subsidiaries, including the funding of acquisitions and investments, payment of capital expenditures and the repurchase of shares.

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 1.75%, depending on the lower rate determined by either the Company’s leverage ratio or the credit rating of the Company’s senior unsecured debt. At March 31, 2025, the applicable all-in margin on the revolving facility was 1.35% (including the credit spread adjustment). The commitment fee payable on the unused portion of the facility is equal to between 0.125% and 0.25% based on utilization of the facility. The Company has also agreed to pay customary letter of credit fees.

Income Taxes

The provision for income taxes was $56.1 million and $49.0 million for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate was 21.0% and 18.9% for the three months ended March 31, 2025 and 2024, respectively. The effective income tax rate is higher in the current year primarily due to larger unrecognized tax benefits compared to the same period in the prior year.

The Company had gross unrecognized tax benefits of $267.2 million on March 31, 2025 and $257.5 million on December 31, 2024.

The Organization for Economic Co-operation and Development (“the OECD”) has issued various tax proposals including a two-pillar approach to global taxation (BEPS 2.0/ Pillar Two), focusing on global profit allocation and a 15% global corporate minimum tax rate. Several countries in which Gartner does business have proposed or enacted new laws to align with OECD Pillar Two proposals. The minimum tax is treated as a current cost beginning in 2024 and does not have a significant impact on the Company's effective tax rate for the current period. Significant details around the provisions are still uncertain as the OECD and participating countries continue to work on defining the underlying rules and administrative procedures. The Company will continue to monitor and reflect the impact of such legislative changes in future financial statements as appropriate.

Derivatives and Hedging

The Company enters into a limited number of derivative contracts to mitigate the cash flow risk associated with changes in interest rates on variable-rate debt and changes in foreign exchange rates on forecasted foreign currency transactions. The Company accounts for its outstanding derivative contracts in accordance with FASB ASC Topic 815, which requires all derivatives, including derivatives designated as accounting hedges, to be recorded on the balance sheet at fair value. The tables below provide information regarding the Company’s outstanding derivative contracts as of the dates indicated (in thousands, except for number of contracts).

(1)Effective June 30, 2020, the Company de-designated all of its interest rate swaps and discontinued hedge accounting. Accordingly, subsequent changes to fair value of the interest rate swap are recorded in Other income, net. The amounts previously recorded in Accumulated other comprehensive loss are amortized into Interest expense, net over the terms of the hedged forecasted interest payments. See Note 7 — Debt for additional information regarding the Company’s interest rate swap contract.

(2)The Company has foreign exchange transaction risk because it typically enters into transactions in the normal course of business that are denominated in foreign currencies that differ from the local functional currency. The Company enters into short-term foreign currency forward exchange contracts to mitigate the cash flow risk associated with changes in foreign currency rates on forecasted foreign currency transactions. These contracts are accounted for at fair value with realized and unrealized gains and losses recognized in Other income, net because the Company does not designate these contracts as hedges for accounting purposes. All of the outstanding foreign currency forward exchange contracts at March 31, 2025 matured before April 30, 2025.

(3)See Note 11 — Fair Value Disclosures for the determination of the fair values of these instruments.

At March 31, 2025, all of the Company’s derivative counterparties were investment grade financial institutions.

Fair Value Disclosures

Fair Value Disclosures

The Company’s financial instruments include cash equivalents, fees receivable from customers, accounts payable and accrued liabilities, all of which are normally short-term in nature. The Company believes that the carrying amounts of these financial instruments reasonably approximate their fair values due to their short-term nature. The Company’s financial instruments also include its outstanding variable-rate borrowings under the 2024 Credit Agreement. The Company believes that the carrying amounts of its variable-rate borrowings reasonably approximate their fair values because the rates of interest on those borrowings reflect current market rates of interest for similar instruments with comparable maturities.

The Company enters into a limited number of derivatives transactions but does not enter into repurchase agreements, securities lending transactions or master netting arrangements. Receivables or payables that result from derivatives transactions are recorded gross in the Company’s Condensed Consolidated Balance Sheets.

FASB ASC Topic 820 provides a framework for the measurement of fair value and a valuation hierarchy based on the transparency of inputs used in the valuation of assets and liabilities. Classification within the valuation hierarchy is based on the lowest level of input that is significant to the resulting fair value measurement. The valuation hierarchy contains three levels. Level 1 measurements consist of quoted prices in active markets for identical assets or liabilities. Level 2 measurements include significant other observable inputs such as quoted prices for similar assets or liabilities in active markets; identical assets or liabilities in inactive markets; observable inputs such as interest rates and yield curves; and other market-corroborated inputs. Level 3 measurements include significant unobservable inputs such as internally-created valuation models. Generally, the Company does not utilize Level 3 valuation inputs to remeasure any of its assets or liabilities. However, Level 3 inputs may be used by the Company when certain long-lived assets, including identifiable intangible assets, goodwill, and right-of-use assets are measured at fair value on a nonrecurring basis when there are indicators of impairment. Additionally, Level 3 inputs may be used by the Company in its required annual impairment review of goodwill. Information regarding the periodic assessment of the Company’s goodwill is included in Note 2 — Goodwill and Intangible Assets. The Company does not typically transfer assets or liabilities between different levels of the valuation hierarchy.

The table below presents the fair values of certain financial assets and liabilities that are measured at fair value on a recurring basis in the Company's financial statements (in thousands).

(1)The Company has a deferred compensation plan for the benefit of certain highly compensated officers, managers and other key employees. The assets consist of investments in money market funds, mutual funds and company-owned life insurance contracts, which are valued based on Level 1 or Level 2 inputs. The related deferred compensation plan liabilities are recorded at fair value, or the estimated amount needed to settle the liability, which the Company considers to be a Level 2 input.

(2)The Company enters into foreign currency forward exchange contracts to hedge the effects of adverse fluctuations in foreign currency exchange rates (see Note 10 — Derivatives and Hedging). Valuation of these contracts is based on observable foreign currency exchange rates in active markets, which the Company considers to be a Level 2 input.

(3)The Company has an interest rate swap contract that hedges the risk of variability from interest payments on its borrowings (see Note 7 — Debt). The fair value of the interest rate swap is based on mark-to-market valuations prepared by a third-party broker. This valuation is based on observable interest rates from recently executed market transactions and other observable market data, which the Company considers to be Level 2 inputs. The Company independently corroborates the reasonableness of the valuations prepared by the third-party broker by using an electronic quotation service.

The table below presents the carrying amounts (net of deferred financing costs) and fair values of financial instruments that are not recorded at fair value in the Company’s Condensed Consolidated Balance Sheets (in thousands). The estimated fair value of the financial instruments was derived from quoted market prices provided by an independent dealer, which the Company considers to be a Level 2 input.

Assets and liabilities measured at fair value on a non-recurring basis

The Company’s certain long-lived assets, including identifiable intangible assets, goodwill, right-of-use assets and other long-lived assets, are measured at fair value on a nonrecurring basis when there are indicators of impairment. The Company recorded an impairment loss during the three months ended March 31, 2024 and $0.5 million on right-of-use assets and other long-lived assets primarily related to certain office leases that the Company determined will no longer be used. The impairments were derived by comparing the fair value of the impacted assets to the carrying value of those assets as of the impairment measurement date, as required under ASC Topic 360 using Level 3 inputs. See Note 13 — Leases for additional discussion related to these impairment charges.

Contingencies

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 Company’s obligations and the unique facts of each particular agreement. Historically, payments made by the Company under

these agreements have not been material. As of March 31, 2025, the Company did not have any material payment obligations under any such indemnification agreements.

Leases [Abstract]

Leases

Leases

The Company’s leasing activities are primarily for facilities under cancelable and non-cancelable lease agreements expiring during 2025 and through 2038. These facilities support our executive and administrative activities, sales, systems support, operations, and other functions. The Company also has leases for office equipment and other assets, which are not significant. Certain of these 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 2025 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.

All of the Company’s leasing and subleasing activity is recognized in Selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The table below presents the Company’s net lease cost and certain other information related to the Company’s leasing activities as of and for the periods indicated (dollars in thousands).

(1)Included in operating lease cost was $8.5 million and $9.2 million for the three months ended March 31, 2025 and 2024, respectively, for costs related to subleasing activities.

(2)These amounts are primarily variable lease and nonlease costs that are not fixed at the lease commencement date or are dependent on something other than an index or a rate.

(3)The Company did not capitalize any operating lease costs during any of the periods presented.

(4)Amount excludes impairment charges on lease related assets, as discussed below.

The table below indicates where the discounted operating lease payments from the above table are classified in the accompanying Condensed Consolidated Balance Sheets (in thousands).

As a result and in consideration of the changing nature of the Company’s use of office space, the Company continues to evaluate its existing real estate lease portfolio. In connection with this evaluation, the Company reviewed certain of its right-of-use assets and related other long-lived assets for impairment under ASC 360. As a result of the evaluation, the Company recognized an impairment loss during the three months ended March 31, 2024 of $0.5 million which is included as a component of Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. The impairment losses recorded include $0.4 million related to right-of-use assets and $0.1 million related to other long-lived assets, primarily leasehold improvements, for the three months ended March 31, 2024.

The fair values for the asset groups relating to the impaired long-lived assets were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair values include the

expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflect the level of risk associated with receiving future cash flows.

Business and Basis of Presentation (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Segments

Segments. Gartner delivers its products and services globally through three business segments: Research, Conferences and Consulting.

Basis of presentation

Basis of presentation. The accompanying interim Condensed 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 270 for interim financial information and with the applicable instructions of U.S. Securities and Exchange Commission (“SEC”) Rule 10-01 of Regulation S-X on Form 10-Q, and should be read in conjunction with the consolidated financial statements and related notes of the Company in its Annual Report on Form 10-K for the year ended December 31, 2024.

The fiscal year of Gartner is the twelve-month period from January 1 through December 31. In the opinion of management, all normal recurring accruals and adjustments considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented herein have been included. The results of operations for the three months ended March 31, 2025 may not be indicative of the results of operations for the remainder of 2025 or beyond. When used in these notes, the terms “Gartner,” the “Company,” “we,” “us,” or “our” refer to Gartner, Inc. and its consolidated subsidiaries.

Principles of consolidation

Principles of consolidation. The accompanying interim Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

Use of estimates

Use of estimates. The preparation of the accompanying interim Condensed 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 estimates and actual results could be material and would be reflected in the Company’s consolidated financial statements in future periods.

Cash and cash equivalents and restricted cash

Cash and cash equivalents and restricted cash. During the three months ended March 31, 2024, the Company paid $0.6 million of restricted cash for deferred consideration related to a 2022 acquisition.

Revenue recognition

Revenue recognition. Revenue is recognized in accordance with the requirements of FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”). Revenue is only recognized when all of the required criteria for revenue recognition have been met. The accompanying Condensed Consolidated Statements of Operations present revenue net of any sales or value-added taxes that we collect from customers and remit to government authorities. ASC Topic 270 requires certain disclosures in interim financial statements around the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Adoption of new accounting standard

Adoption of new accounting standard. The Company adopted the accounting standard described below during 2024.

Segment Reporting— In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements in Reportable Segment Disclosures (“ASU 2023-07”). The amendments in the ASU are expected to improve disclosures about a public entity’s reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. ASU 2023-07 requires public companies to disclose, on an annual and interim basis, significant expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit and loss. The amendments in the ASU require that a public company provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under ASC 280 in interim periods. The amendments in the ASU also require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. The amendments in the ASU, among other items, also require that a public company disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU applies to all public entities that are required to report segment information in accordance with Topic 280. All public entities are required to report segment information in accordance with the new guidance starting in annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 effective with the 2024 10-K and the adoption only impacted its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Accounting standards issued but not yet adopted. The FASB has issued accounting standards that have not yet become effective as of March 31, 2025 and may impact the Company’s Consolidated Financial Statements or related disclosures in future periods. The standards and their potential impacts are discussed below.

Income Taxes— In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 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 expects this ASU to only impact its disclosures with no impacts to the Company's results of operations, cash flows, or financial condition.

Income Statement— In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income- Expense Disaggregation Disclosures (“ASU 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.

(1)Effective June 30, 2020, the Company de-designated all of its interest rate swaps and discontinued hedge accounting. Accordingly, subsequent changes to fair value of the interest rate swap are recorded in Other income, net. The amounts previously recorded in Accumulated other comprehensive loss are amortized into Interest expense, net over the terms of the hedged forecasted interest payments. See Note 7 — Debt for additional information regarding the Company’s interest rate swap contract.

(2)The Company has foreign exchange transaction risk because it typically enters into transactions in the normal course of business that are denominated in foreign currencies that differ from the local functional currency. The Company enters into short-term foreign currency forward exchange contracts to mitigate the cash flow risk associated with changes in foreign currency rates on forecasted foreign currency transactions. These contracts are accounted for at fair value with realized and unrealized gains and losses recognized in Other income, net because the Company does not designate these contracts as hedges for accounting purposes. All of the outstanding foreign currency forward exchange contracts at March 31, 2025 matured before April 30, 2025.

Total Liabilities	$	150,077	$	150,432

(1)The Company has a deferred compensation plan for the benefit of certain highly compensated officers, managers and other key employees. The assets consist of investments in money market funds, mutual funds and company-owned life insurance contracts, which are valued based on Level 1 or Level 2 inputs. The related deferred compensation plan liabilities are recorded at fair value, or the estimated amount needed to settle the liability, which the Company considers to be a Level 2 input.

(2)The Company enters into foreign currency forward exchange contracts to hedge the effects of adverse fluctuations in foreign currency exchange rates (see Note 10 — Derivatives and Hedging). Valuation of these contracts is based on observable foreign currency exchange rates in active markets, which the Company considers to be a Level 2 input.

(3)The Company has an interest rate swap contract that hedges the risk of variability from interest payments on its borrowings (see Note 7 — Debt). The fair value of the interest rate swap is based on mark-to-market valuations prepared by a third-party broker. This valuation is based on observable interest rates from recently executed market transactions and other observable market data, which the Company considers to be Level 2 inputs. The Company independently corroborates the reasonableness of the valuations prepared by the third-party broker by using an electronic quotation service.
