Notes Regarding the Use of Operating Metrics MSCI has presented supplemental key operating metrics as part of this earnings release, including Run Rate,Retention Rate, subscription sales, subscription cancellations and non-recurring sales. A substantial portion of MSCI’s operating revenues is derived from recurring subscriptions or licenses for productsand services that are ongoing in nature and provided over contractually agreed periods, which are subject torenewal or cancellation upon the expiration of the then-current term. In addition, we generate non-recurringrevenues from one-time sales and other transactions or services that are discrete in nature or that have a definedlife. The operating metrics defined below help management assess the stability and growth of this recurring-revenue base and track non-recurring revenues. There have been no changes to the methodologies used tocompute these metrics compared with prior periods. Run Rate estimates, at a specific point in time, the annualized value of the recurring portion of executed clientcontracts (“Client Contracts”) expected to generate revenues over the next 12 months, assuming that all suchClient Contracts are renewed and using fixed foreign exchange rates. Run Rate includes new Client Contractsupon execution, even if the license start date and related revenue recognition occur later. For Client Contracts where fees are linked to an investment product’s assets or trading volume or fees (referred toas “Asset-based Fees”), the Run Rate calculation is based on: • For exchange-traded funds (“ETFs”): assets under management as of the last trading day of the period; • For non-ETF products: the most recent client-reported assets under management; and • For listed futures and options contracts: the most recent quarterly volumes and/or reported exchange fees. Run Rate excludes fees associated with one-time or other non-recurring transactions.We remove from Run Rate the annualized fee value associated with products or services under any ClientContracts when (i) we have received a notice of termination, reduction in fees, non-renewal or other clearindication that the client does not intend to continue its subscription at then current fees; and (ii) management hasdetermined that such notice or indication reflects the client’s final decision to terminate, not renew or renew at alower fee the applicable products or services, even if such termination or non-renewal is not yet effective (eachsuch event, a “Subscription Cancellation”). In general, when a client reduces the fees paid to MSCI associated with a reduction in the number of products orservices to which it subscribes within a segment, or a switch between products or services within a segment,unless the client switches to a product or service that management considers a replacement, such reduction orswitch is treated as a Subscription Cancellation, including for purposes of calculating MSCI’s Retention Rate (asdetailed below). In the cases where the client switches products or services to a replacement service, only the netdecrease, if any, is reported as a cancellation. • In the Analytics and Sustainability and Climate operating segments, substantially all such product or serviceswitches are treated as replacements and are netted accordingly. 8

• In contrast, in the Index, Real Assets, and Private Capital Solutions operating segments, such nettingtreatment is applied only in limited circumstances. Organic recurring subscription Run Rate growth is defined as the period-over-period growth in Run Rate,excluding: • The impact of changes in foreign currency exchange rates; • The impact of acquisitions during the first 12 months following the transaction date; and • The impact of divestitures, where Run Rate from divested businesses are excluded from prior period RunRates. Retention Rate is a key performance metric that provides insight into the stability and durability of MSCI’s recurringrevenue base. Subscription cancellations reduce Run Rate and, over time, lower future operating revenues. For full-year periods, Retention Rate is calculated as the retained subscription Run Rate, which is defined as thesubscription Run Rate at the beginning of the fiscal year minus actual subscription cancellations during the fiscalyear, expressed as a percentage of the subscription Run Rate at the beginning of the fiscal year. For interim (non-annual) periods, Retention Rate is presented on an annualized basis. The annualized RetentionRate is calculated by: 1. Dividing annualized subscription cancellations in the period by the subscription Run Rate at the beginningof the fiscal year, to determine a cancellation rate; and 2. Subtracting that rate from 100%, to derive the annualized Retention Rate. Retention Rate is calculated by operating segment and is based on an individual product or service level withineach segment. We do not calculate Retention Rate for the portion of Run Rate attributable to Asset-based Fees. Sales represents the annualized value of products and services that clients have committed to purchase fromMSCI and that are expected to result in additional operating revenues. Non-recurring sales represent the aggregate value of client agreements entered into during the period thatgenerate non-recurring fees and are not included in Run Rate (as defined elsewhere herein), even if suchagreements span multiple periods or years. New recurring subscription sales represent the annualized value of additional client commitments entered intoduring the period - such as new Client Contracts, expansions of existing Client Contracts or price increases - thatcontribute to Run Rate. Net new recurring subscription sales represent new recurring subscription sales minus the impact of SubscriptionCancellations, capturing the net impact to Run Rate for the period. Total gross sales is the sum of new recurring subscription sales and non-recurring sales. Total net sales is total gross sales minus the impact of Subscription Cancellations. In the third quarter 2025, MSCI updated the presentation of certain client segments to align with our client-servicing and go-to-market approaches. The commentary regarding Run Rate in this earnings release reflectsthese updated client segments. These changes are presentation updates only and do not impact MSCI’s GAAPoperating segments, reported revenues, or consolidated Subscription Run Rate for any period presented. Notes Regarding the Use of Non-GAAP Financial Measures MSCI has presented supplemental non-GAAP financial measures as part of this earnings release. Reconciliationsare provided in Tables 9 through 14 below that reconcile each non-GAAP financial measure with the mostcomparable GAAP measure. The non-GAAP financial measures presented in this earnings release should not beconsidered as alternative measures for the most 9
Page 10
directly comparable GAAP financial measures. The non-GAAP financial measures presented in this earningsrelease are used by management to monitor the financial performance of the business, inform business decision-making and forecast future results. “Adjusted EBITDA” is defined as net income before (1) provision for income taxes, (2) other expense (income),net, (3) depreciation and amortization of property, equipment and leasehold improvements, (4) amortization ofintangible assets and, at times, (5) certain other transactions or adjustments, including, when applicable, certainacquisition-related integration and transaction costs. “Adjusted EBITDA expenses” is defined as operating expenses less depreciation and amortization of property,equipment and leasehold improvements and amortization of intangible assets and, at times, certain othertransactions or adjustments, including, when applicable, certain acquisition-related integration and transactioncosts. “Adjusted EBITDA margin” is defined as adjusted EBITDA divided by operating revenues. “Adjusted net income” and “adjusted EPS” are defined as net income and diluted EPS, respectively, before theafter-tax impact of: the amortization of acquired intangible assets and, at times, certain other transactions oradjustments, including, when applicable, the impact related to certain acquisition-related integration andtransaction costs and the impact related to write-off of deferred fees on debt extinguishment. “Capex” is defined as capital expenditures plus capitalized software development costs. “Free cash flow” is defined as net cash provided by operating activities, less Capex. “Organic operating revenue growth” is defined as operating revenue growth compared to the prior year periodexcluding the impact of acquired businesses, divested businesses and foreign currency exchange ratefluctuations. Asset-based fees ex-FX does not adjust for the impact from foreign currency exchange rate fluctuations on theunderlying assets under management (“AUM”). We believe adjusted EBITDA, adjusted EBITDA margin and adjusted EBITDA expenses are meaningful measuresof the operating performance of MSCI because they adjust for significant one-time, unusual or non-recurring itemsas well as eliminate the accounting effects of certain capital spending and acquisitions that do not directly affectwhat management considers to be our ongoing operating performance in the period. We believe adjusted net income and adjusted EPS are meaningful measures of the performance of MSCI becausethey adjust for the after-tax impact of significant one-time, unusual or non-recurring items as well as eliminate theimpact of any transactions that do not directly affect what management considers to be our ongoing operatingperformance in the period. We also exclude the after-tax impact of the amortization of acquired intangible assetsand amortization of the basis difference between the cost of the equity method investment and MSCI’s share ofthe net assets of the investee at historical carrying value, as these non-cash amounts are significantly impacted bythe timing and size of each acquisition and therefore not meaningful to the ongoing operating performance in theperiod. We believe that free cash flow is useful to investors because it relates the operating cash flow of MSCI to thecapital that is spent to continue and improve business operations, such as investment in MSCI’s existing products.Further, free cash flow indicates our ability to strengthen MSCI’s balance sheet, repay our debt obligations, paycash dividends and repurchase shares of our common stock. We believe organic operating revenue growth is a meaningful measure of the operating performance of MSCIbecause it adjusts for the impact of foreign currency exchange rate fluctuations and excludes the impact ofoperating revenues attributable to acquired and divested businesses for the comparable prior year period,providing insight into our ongoing operating performance for the period(s) presented. 10

We believe that the non-GAAP financial measures presented in this earnings release facilitate meaningful period-to-period comparisons and provide a baseline for the evaluation of future results. Adjusted EBITDA expenses, adjusted EBITDA margin, adjusted EBITDA, adjusted net income, adjusted EPS,Capex, free cash flow and organic operating revenue growth are not defined in the same manner by all companiesand may not be comparable to similarly-titled non-GAAP financial measures of other companies. These measurescan differ significantly from company to company depending on, among other things, long-term strategic decisionsregarding capital structure, the tax jurisdictions in which companies operate and capital investments. Accordingly,the Company’s computation of these measures may not be comparable to similarly-titled measures computed byother companies. Notes Regarding Adjusting for the Impact of Foreign Currency Exchange Rate Fluctuations Foreign currency exchange rate fluctuations reflect the difference between the current period results as reportedcompared to the current period results recalculated using the foreign currency exchange rates in effect for thecomparable prior period. While operating revenues adjusted for the impact of foreign currency fluctuationsincludes asset-based fees that have been adjusted for the impact of foreign currency fluctuations, the underlyingAUM, which is the primary component of asset-based fees, is not adjusted for foreign currency fluctuations.Approximately three-fifths of the AUM is invested in securities denominated in currencies other than the U.S.dollar, and any such impact is excluded from the disclosed foreign currency-adjusted variances. 11
