“MSCI delivered another quarter of strong financial performance, along with 17 percent asset-based-fee (ABF) run-rate growth fueled by record AUM levels in ETF products linked to our indexes. In fact, we saw more cash flows into equity ETFs tied to our indexes than any other index provider. Among client segments, we posted double-digit subscription run-rate growth with banks and broker-dealers, wealth managers, hedge funds, and asset owners, plus steady growth and high retention with asset managers,” said Henry A. Fernandez, Chairman and CEO of MSCI.

“Across all segments, MSCI is expanding our existing solutions to support different use cases while developing new solutions for an increasingly diverse client base. We continue to benefit from our resilient financial model and integrated products, which offer the scalability, depth, and innovation clients need to advance their strategies,” Mr. Fernandez added.

Second Quarter Consolidated Results

Operating Revenues: Operating revenues were $772.7 million, up 9.1%. Organic operating revenue growth was 8.3%. The $64.7 million increase was the result of $41.3 million in higher recurring subscription revenues and $20.8 million in higher asset-based fees.

Run Rate and Retention Rate: Total Run Rate at June 30, 2025 was $3,106.7 million, up 10.7%. Recurring subscription Run Rate increased by $188.9 million, and asset-based fees Run Rate increased by $110.5 million. Organic recurring subscription Run Rate growth was 7.4%. Retention Rate in second quarter 2025 was 94.4%, compared to 94.8% in second quarter 2024.

Expenses: Total operating expenses were $347.4 million, up 6.8%. Adjusted EBITDA expenses were $298.3 million, up 7.3%, primarily reflecting higher compensation and benefits costs as a result of increased headcount costs as well as higher severance costs, partially offset by an adjustment to the fair value of contingent consideration related to the Fabric acquisition.

Total operating expenses excluding the impact of foreign currency exchange rate fluctuations (“ex-FX”) and adjusted EBITDA expenses ex-FX increased 6.1% and 6.5%, respectively.

Operating Income: Operating income was $425.2 million, up 11.1%. Operating income margin in second quarter 2025 was 55.0%, compared to 54.0% in second quarter 2024.

Headcount: As of June 30, 2025, we had 6,208 employees, reflecting a 2.5% increase, with 29.6% and 70.4% of employees located in developed market and emerging market locations, respectively.

Other Expense (Income), Net: Other expense (income), net was $47.4 million, up 11.2%, primarily driven by lower interest income reflecting lower average cash balances as well as unfavorable foreign currency exchange rate fluctuations.

Income Taxes: The effective tax rate was 19.6% in the second quarter 2025 compared to 21.5% in second quarter 2024. The effective tax rate was driven lower by the non-taxable contingent consideration adjustment discussed above, compared to unfavorable discrete items in the prior year.

Net Income: As a result of the factors described above, net income was $303.7 million, up 13.8%.

Adjusted EBITDA: Adjusted EBITDA was $474.4 million, up 10.3%. Adjusted EBITDA margin in second quarter 2025 was 61.4%, compared to 60.7% in second quarter 2024.

Index operating revenues were $434.8 million, up 9.5%. The $37.6 million increase was primarily driven by $20.8 million in higher asset-based fees and $18.6 million in higher recurring subscription revenues. Organic operating revenue growth for Index was 9.3%.

The growth in recurring subscription revenues was primarily driven by growth from market-cap weighted Index products.

The growth in revenues attributed to asset-based fees was primarily driven by ETFs linked to MSCI equity indexes and non-ETF indexed funds linked to MSCI indexes, in each case primarily driven by increased average AUM.

Index Run Rate as of June 30, 2025, was $1.7 billion, up 12.2%. The $187.6 million increase was comprised of a $110.5 million increase in asset-based fees Run Rate and a $77.1 million increase in recurring subscription Run Rate. The increase in asset-based fees Run Rate was primarily driven by higher AUM in both ETFs linked to MSCI equity indexes and non-ETF indexed funds linked to MSCI indexes. The increase in recurring subscription Run Rate was primarily driven by growth from market cap-weighted and custom Index products. The increase reflected growth across all regions and client segments. Organic recurring subscription Run Rate growth for Index was 8.6%.

Full-Year 2025 Guidance

MSCI’s guidance for the year ending December 31, 2025 (“Full-Year 2025”) is based on assumptions about a number of factors, in particular related to macroeconomic factors and the capital markets. These assumptions are subject to uncertainty, and actual results for the year could differ materially from our current guidance, including as a result of the uncertainties, risks and assumptions discussed in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of our Annual Report on Form 10-K, as updated in quarterly reports on Form 10-Q and current reports on Form 8-K filed or furnished with the SEC. See “Forward-Looking Statements” below.

Guidance Item			Current Guidance for Full-Year 2025
Operating Expense			$1,405 to $1,445 million
Adjusted EBITDA Expense			$1,220 to $1,250 million
Interest Expense (including amortization of financing fees)(1)			$182 to $186 million
Depreciation & Amortization Expense			$185 to $195 million
Effective Tax Rate			17.5% to 20.0%
Capital Expenditures			$115 to $125 million
Net Cash Provided by Operating Activities			$1,525 to $1,575 million
Free Cash Flow			$1,400 to $1,460 million

(1) A portion of our annual interest expense is from our variable rate indebtedness under our revolving credit facility, while the majority is from fixed rate senior unsecured notes. Changes to the secured overnight funding rate (“SOFR”) and indebtedness levels can cause our annual interest expense to vary.

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 products and services that are ongoing in nature and provided over contractually agreed periods, which are subject to renewal or cancellation upon the expiration of the then-current term. In addition, we generate non-recurring revenues from one-time sales and other transactions or services that are discrete in nature or that have a defined life. 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 to compute these metrics compared with prior periods.

Run Rate estimates, at a specific point in time, the annualized value of the recurring portion of executed client contracts (“Client Contracts”) expected to generate revenues over the next 12 months, assuming that all such Client Contracts are renewed and using foreign exchange rates at such point in time. Run Rate includes new Client Contracts upon 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 to as “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 Client Contracts when (i) we have received a notice of termination, reduction in fees, non-renewal or other clear indication that the client does not intend to continue its subscription at then current fees; and (ii) management has determined that such notice or indication reflects the client’s final decision to terminate, not renew or renew at a lower fee the applicable products or services, even if such termination or non-renewal is not yet effective (each such event, a “Subscription Cancellation”).

In general, when a client reduces the fees paid to MSCI associated with a reduction in the number of products or services 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 or switch is treated as a Subscription Cancellation, including for purposes of calculating MSCI’s Retention Rate (as detailed below). In the cases where the client switches products or services to a replacement service, only the net decrease, if any, is reported as a cancellation.

•In the Analytics and Sustainability and Climate operating segments, substantially all such product or service switches are treated as replacements and are netted accordingly.

•In contrast, in the Index, Real Assets, and Private Capital Solutions operating segments, such netting treatment 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 Run Rates.

Retention Rate is a key performance metric that provides insight into the stability and durability of MSCI’s recurring revenue 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 the subscription Run Rate at the beginning of the fiscal year minus actual subscription cancellations during the fiscal year, 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 Retention Rate is calculated by:

1.Dividing annualized subscription cancellations in the period by the subscription Run Rate at the beginning of 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 within each 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 from MSCI 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 that generate non-recurring fees and are not included in Run Rate (as defined elsewhere herein), even if such agreements span multiple periods or years.

New recurring subscription sales represent the annualized value of additional client commitments entered into during the period - such as new Client Contracts, expansions of existing Client Contracts or price increases - that contribute to Run Rate.

Net new recurring subscription sales represent new recurring subscription sales minus the impact of Subscription Cancellations, 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.

Notes Regarding the Use of Non-GAAP Financial Measures

MSCI has presented supplemental non-GAAP financial measures as part of this earnings release. Reconciliations are provided in Tables 9 through 14 below that reconcile each non-GAAP financial measure with the most comparable GAAP measure. The non-GAAP financial measures presented in this earnings release should not be considered as alternative measures for the most directly comparable GAAP financial measures. The non-GAAP financial measures presented in this earnings release 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 of intangible assets and, at times, (5) certain other transactions or adjustments, including, when applicable, certain acquisition-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 other transactions or adjustments, including, when applicable, certain acquisition-related integration and transaction costs.

“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 the after-tax impact of: the amortization of acquired intangible assets and, at times, certain other transactions or adjustments, including, when applicable, the impact related to certain acquisition-related integration and transaction 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 period excluding the impact of acquired businesses, divested businesses and foreign currency exchange rate fluctuations.

Asset-based fees ex-FX does not adjust for the impact from foreign currency exchange rate fluctuations on the underlying assets under management (“AUM”).

We believe adjusted EBITDA, adjusted EBITDA margin and adjusted EBITDA expenses are meaningful measures of the operating performance of MSCI because they adjust for significant one-time, unusual or non-recurring items as well as eliminate the accounting effects of certain capital spending and acquisitions that do not directly affect what 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 because they adjust for the after-tax impact of significant one-time, unusual or non-recurring items as well as eliminate the impact of any transactions that do not directly affect what management considers to be our ongoing operating performance in the period. We also exclude the after-tax impact of the amortization of acquired intangible assets and amortization of the basis difference between the cost of the equity method investment and MSCI’s share of the net assets of the investee at historical carrying value, as these non-cash amounts are significantly impacted by the timing and size of each acquisition and therefore not meaningful to the ongoing operating performance in the period.

We believe that free cash flow is useful to investors because it relates the operating cash flow of MSCI to the capital 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, pay cash dividends and repurchase shares of our common stock.

We believe organic operating revenue growth is a meaningful measure of the operating performance of MSCI because it adjusts for the impact of foreign currency exchange rate fluctuations and excludes the impact of operating 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.

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 companies and may not be comparable to similarly-titled non-GAAP financial measures of other companies. These measures can differ significantly from company to company depending on, among other things, long-term strategic decisions regarding 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 by other 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 reported compared to the current period results recalculated using the foreign currency exchange rates in effect for the comparable prior period. While operating revenues adjusted for the impact of foreign currency fluctuations includes asset-based fees that have been adjusted for the impact of foreign currency fluctuations, the underlying AUM, 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.

(1) We have not provided a full line-item reconciliation for total operating expenses to adjusted EBITDA expenses for this future period because we believe such a reconciliation would imply a degree of precision and certainty that could be confusing to investors and we are unable to reasonably predict certain items contained in the GAAP measure without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing or amount of various items that have not yet occurred and are out of the Company's control or cannot be reasonably predicted. For the same reasons, the Company is unable to address the probable significance of the unavailable information.
