MSCI Inc.

Our consolidated financial statements are prepared in accordance with GAAP. These accounting principles require us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the periods presented. Significant estimates and judgments made by management include such examples as assessment of impairment of goodwill and intangible assets and income taxes. We believe the estimates and judgments upon which we rely are reasonable based upon information available to us at the time these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected.

We recognize goodwill in business combination transactions when the purchase price exceeds the fair value of the acquired net tangible and separately identifiable intangible assets. We test goodwill for impairment annually on July 1 or when interim triggers arise. When testing goodwill for impairment, we first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test; however, on a periodic basis, we may elect to bypass the qualitative assessment and proceed directly to the quantitative test. During the year ended December 31, 2025, the Company has selected to bypass the optional qualitative assessment for the Real Assets and Private Capital Solutions (“PCS”) reporting units. This decision was based on the relatively low excess of fair value over carrying value observed in the prior year’s analysis. Therefore, a quantitative goodwill impairment test was performed for both Real Assets and PCS. For the Index, Analytics, and Sustainability and Climate reporting units, the company performed a qualitative assessment. The quantitative test for impairment used an equal weighting of the income approach and the market approach to estimate the fair value of the Real Assets and PCS reporting units.

The income approach requires significant judgment in estimating future cash flows, including assumptions, amongst others, about revenue growth rates and EBITDA margins, and the selection of an appropriate discount rate, which reflects the reporting unit’s cost of capital. Forecasted future cash flows are estimated based on a combination of historical experience and assumptions regarding future growth and profitability of each reporting unit. Discount rates are selected for each reporting unit being valued based on each reporting unit’s estimated weighted-average cost of capital. The weighted-average cost of capital is estimated based on both the capital structure that we believe a market participant would utilize as well as the discount rates of guideline public companies that have similar characteristics to each reporting unit being valued, adjusted for the risk inherent in each reporting unit. Terminal growth rates are selected based on growth rates used during the reporting unit’s forecast period in combination with economic conditions. The market approach utilizes valuation multiples of revenue and cash flows derived from guideline public companies that have similar characteristics to each reporting unit being valued. Selecting appropriate guideline companies, valuation multiples and other key assumptions such as revenue growth rates and discount rates requires significant management judgment, and changes to these estimates could materially impact the fair value determination of each reporting unit. We perform sensitivity analyses around key assumptions in order to assess the reasonableness of the assumptions and the impact on the estimated fair value.

Impairment occurs when the estimated fair value of the reporting unit is below the carrying value. As of July 1, 2025, all reporting units had fair values exceeding their carrying values. As a result, no goodwill impairment was recorded as of this date.

We completed our annual goodwill impairment test as of July 1, 2025 on our Index, Analytics, Sustainability and Climate, Real Assets and Private Capital Solutions reporting units, which are also our operating segments. At December 31, 2025, the carrying value of goodwill within the Real Assets and Private Capital Solutions reporting units were $691 million and $618 million, respectively. As of July 1, 2025, the fair value of the Real Assets and Private Capital Solutions reporting units exceeded their carrying values by approximately 39% and 15%, respectively. If we experience a prolonged or severe period of weakness in the business environment, financial markets, the performance of one or more of our recently acquired companies or reporting units, or our common stock price, or if economic conditions differ significantly from management’s assumptions, our goodwill could be impaired in the future, which may be material to our results of operations and financial position.

For the Real Assets and PCS reporting units, individually, a hypothetical decrease in revenue growth rates by 100 basis points or a hypothetical 100 basis point increase in the weighted average cost of capital would not result in an impairment. See Note 1, “Introduction and Basis of Presentation” and Note 9, “Goodwill and Intangible Assets, Net” of the Notes to the Consolidated Financial Statements included herein for additional information on goodwill.

Definite Lived Intangible Assets

Definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset or asset group may not be recoverable. These events or circumstances include adverse changes in the manner in which the asset will be used, adverse changes in legal factors related to the asset or negative changes in expected financial performance of the asset, including accumulation of costs and operating losses. Determining whether an event or changes in circumstances warrant an impairment review involves management judgment.

Once it is determined that an impairment review is necessary, recoverability is determined based on comparing the carrying amount of the asset group to the estimated future undiscounted cash flows. If the carrying amount exceeds the estimated future undiscounted cash flows, the asset grouping is considered to be impaired. Measurement of impairment for intangible assets is based on the amount the carrying value exceeds the fair value of the asset, which is based on estimated discounted future cash flows. Estimated undiscounted and discounted cash flows used in the determination and calculation of impairments represent management forecasts and require significant management judgment. While management believes that its forecasts are reasonable, differences between forecasts and actual experience could materially affect the valuations. There were no events or changes in circumstances that would indicate that the carrying value of the definite-lived intangible assets may not be recoverable during the years presented.

We amortize our intangible assets over the estimated period of economic benefit. If the estimated period of economic benefit is changed, the prospective amortization of the intangible asset could materially change.

See Note 1, “Introduction and Basis of Presentation” and Note 9, “Goodwill and Intangible Assets, Net” of the Notes to the Consolidated Financial Statements included herein for additional information on intangible assets and amortization expense.

We are subject to income taxes in the U.S. and other foreign jurisdictions. Our tax provision is an estimate based on our understanding of laws in federal, state and foreign tax jurisdictions. These laws can be complicated and are difficult to apply to any business. The tax laws also require us to allocate our taxable income to many jurisdictions based on subjective allocation methodologies and information collection processes.

Provision for income taxes is provided for using the asset and liability method, under which deferred tax assets and deferred tax liabilities are determined based on the temporary differences between the financial statement and income tax bases of assets and liabilities using currently enacted tax rates. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that all or some portion of the deferred tax assets will not be realized. In assessing the need for a valuation allowance, management is required to estimate future taxable income which requires judgment.

We must regularly assess the likelihood of additional assessments in each of the taxing jurisdictions in which we file income tax returns and adjust unrecognized tax benefits when additional information is available or when an event occurs. This assessment requires significant judgment in assessment of tax laws, frequency of tax examinations, and the nature of intercompany transactions and tax positions.

See Note 1, “Introduction and Basis of Presentation” and Note 12, “Income Taxes” of the Notes to the Consolidated Financial Statements included herein for additional information on income taxes.
