"MSCI delivered impressive results to close out 2023, despite continued external headwinds. In the fourth quarter, we achieved Adjusted EPS growth of nearly 30%, and organic revenue growth of 14.7%. Operationally, we completed our 10th consecutive year of double-digit subscription run-rate growth in Index, while achieving our highest-ever full-year retention rate in Analytics, along with our best quarter and full year on record for recurring sales in Equity Analytics," said Henry A. Fernandez, Chairman and CEO of MSCI.

"We continue to capitalize on important secular trends that are reshaping the global investment landscape, such as rising demand for portfolio customization at scale. Looking ahead, MSCI remains committed to making organic investments and bolt-on acquisitions that add value, while returning excess capital to our owners through share buybacks and dividend payments. As always, we will balance our long-term strategic investments with our commitment to rigorous financial management and short-term execution," Mr. Fernandez added.

Fourth Quarter Consolidated Results

Operating Revenues: Operating revenues were $690.1 million, up 19.8%. Organic operating revenue growth was 14.7%. The $113.9 million increase was driven by $72.9 million in higher recurring subscription revenues and $21.1 million in higher non-recurring revenues primarily related to the Index and Analytics segments, as well as $19.9 million in higher asset-based fees.

Run Rate and Retention Rate: Total Run Rate at December 31, 2023 was $2,686.2 million, up 15.8%. Recurring subscription Run Rate increased by $289.2 million, and asset-based fees Run Rate increased by $76.6 million. Organic recurring subscription Run Rate growth was 9.9%. Retention Rate in fourth quarter 2023 was 93.6%, compared to 93.0% in fourth quarter 2022.

Expenses: Total operating expenses were $319.4 million, up 19.4%, including $33.4 million associated with The Burgiss Group, LLC ("Burgiss") and Trove Research Ltd ("Trove"). Adjusted EBITDA expenses were $275.5 million, up 16.1%, primarily reflecting higher compensation and incentive compensation expenses related to higher headcount to support business growth, partially offset by lower severance costs. Adjusted EBITDA expense also includes $22.6 million of expenses associated with Burgiss and Trove. Approximately $1.4 million in non-recurring integration and transaction costs related to the acquisition of Burgiss and $9.3 million of acquired intangible assets amortization expenses related to Burgiss and Trove were excluded from Adjusted EBITDA expenses. Total operating expenses excluding the impact of foreign currency exchange rate fluctuations ("ex-FX") and adjusted EBITDA expenses ex-FX increased 17.6% and 14.2%, respectively.

Operating Income: Operating income was $370.7 million, up 20.1%. Operating income margin in fourth quarter 2023 was 53.7%, compared to 53.6% in fourth quarter 2022.

Headcount: As of December 31, 2023, headcount was 5,794 employees, with approximately 33.5% and approximately 66.5% of employees located in developed market and emerging market locations, respectively.

Other Expense (Income), Net: Other expense (income), net was ($97.1) million in fourth quarter 2023, as compared to $43.1 for the fourth quarter 2022, primarily driven by the non-taxable, one-time gain on the remeasurement of our equity method investment in Burgiss of $143.0 million, partially offset by lower interest income due to lower cash balance and higher interest expense due to higher interest rates.

Income Taxes: In the fourth quarter 2023, the effective tax rate was 13.8% compared to 19.1% in the fourth quarter 2022, primarily due to the non-taxable, one-time gain on the remeasurement of our equity method investment in Burgiss of $143.0 million and a discrete benefit related to a favorable outcome on the application of a foreign tax law change received late in the quarter, partially offset by an increase due to accruals related to open tax audits.

Net Income: As a result of the factors described above, net income was $403.4 million, up 87.6%.

Adjusted EBITDA: Adjusted EBITDA was $414.6 million, up 22.3%. Adjusted EBITDA margin in fourth quarter 2023 was 60.1%, compared to 58.8% in fourth quarter 2022.

Index operating revenues were $388.0 million, up 17.8%. The $58.7 million increase was driven by $20.8 million in higher recurring subscription revenues, $19.9 million in higher asset-based fees, as well as $18.1 million in higher non-recurring revenues.

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

Revenues from ETFs linked to MSCI equity indexes, mainly driven by an increase in average AUM, drove more than half of the increase in revenues attributable to asset-based fees. The balance of the increase was contributed by non-ETF indexed funds linked to MSCI indexes, driven by an increase in average AUM as well as an increase in average basis point fees.

Non-recurring revenues were $32.1 million, up 128.5%. The $18.1 million increase was primarily driven by $16 million related to fees for unlicensed usage of our content in historical periods, which is recognized in the current period given the signing of an agreement during the quarter to be paid for that past usage.

Index Run Rate as of December 31, 2023 was $1.5 billion, up 12.4%. The $160.4 million increase was comprised of a $83.7 million increase in recurring subscription Run Rate, as well as $76.6 million increase in asset-based fees Run Rate. The increase in recurring subscription Run Rate was driven by growth from market cap-weighted products, custom Index products and special packages as well as factor, ESG and climate products, and reflected growth across all regions and client segments. The increase in asset-based fees Run Rate primarily reflected growth in AUM in ETFs linked to MSCI equity indexes and non-ETF indexed funds linked to MSCI indexes, partially offset by lower exchanged traded futures and options volume.

Full-Year 2024 Guidance

MSCI's guidance for the year ending December 31, 2024 ("Full-Year 2024") 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.

Notes Regarding the Use of Operating Metrics

MSCI has presented supplemental key operating metrics as part of this earnings release, including Retention Rate, Run Rate, subscription sales, subscription cancellations and non-recurring sales.

Retention Rate is an important metric because subscription cancellations decrease our Run Rate and ultimately our operating revenues over time. The annual Retention Rate represents the retained subscription Run Rate (subscription Run Rate at the beginning of the fiscal year less actual cancels during the year) as a percentage of the subscription Run Rate at the beginning of the fiscal year.

The Retention Rate for a non-annual period is calculated by annualizing the cancellations for which we have received a notice of termination or for which we believe there is an intention not to renew or discontinue the subscription during the non-annual period, and we believe that such notice or intention evidences the client's final decision to terminate or not renew the applicable agreement, even though such notice is not effective until a later date. This annualized cancellation figure is then divided by the subscription Run Rate at the beginning of the fiscal year to calculate a cancellation rate. This cancellation rate is then subtracted from 100% to derive the annualized Retention Rate for the period.

Retention Rate is computed by operating segment on a product/service-by-product/service basis. In general, if a client reduces the number of products or services to which it subscribes within a segment, or switches between products or services within a segment, we treat it as a cancellation for purposes of calculating our Retention Rate except in the case of a product or service switch that management considers to be a replacement product or service. In those replacement cases, only the net change to the client subscription, if a decrease, is reported as a cancellation. In the Analytics and the ESG and Climate operating segments, substantially all product or service switches are treated as replacement products or services and netted in this manner, while in our Index and Real Assets operating segments, product or service switches that are treated as replacement products or services and receive netting treatment occur only in certain limited instances. In addition, we treat any reduction in fees resulting from a down-sell of the same product or service as a cancellation to the extent of the reduction. We do not calculate Retention Rate for that portion of our Run Rate attributable to assets in index-linked investment products or futures and options contracts, in each case, linked to our indexes.

Run Rate estimates at a particular point in time the annualized value of the recurring revenues under our client license agreements ("Client Contracts") for the next 12 months, assuming all Client Contracts that come up for renewal, or reach the end of the committed subscription period, are renewed and assuming then-current currency exchange rates, subject to the adjustments and exclusions described below. For any Client Contract where fees are linked to an investment product's assets or trading volume/fees, the Run Rate calculation reflects, for ETFs, the market value on the last trading day of the period, for futures and options, the most recent quarterly volumes and/or reported exchange fees, and for other non-ETF products, the most recent client-reported assets. Run Rate does not include fees associated with "one-time" and other non-recurring transactions. In addition, we add to Run Rate the annualized fee value of recurring new sales, whether to existing or new clients, when we execute Client Contracts, even though the license start date, and associated revenue recognition, may not be effective until a later date. We remove from Run Rate the annualized fee value associated with products or services under any Client Contract with respect to which we have received a notice of termination, non-renewal or an indication the client does not intend to continue their subscription during the period and have determined that such notice evidences the client's final decision to terminate or not renew the applicable products or services, even though such notice is not effective until a later date.

"Organic recurring subscription Run Rate growth" is defined as the period over period Run Rate growth, excluding the impact of changes in foreign currency and the first year impact of any acquisitions. It is also adjusted for divestitures. Changes in foreign currency are calculated by applying the currency exchange rate from the comparable prior period to current period foreign currency denominated Run Rate.

Sales represents the annualized value of products and services clients commit to purchase from MSCI and will result in additional operating revenues. Non-recurring sales represent the actual value of the customer agreements entered into during the period and are not a component of Run Rate. New recurring subscription sales represent additional selling activities, such as new customer agreements, additions to existing agreements or increases in price that occurred during the period and are additions to Run Rate. Subscription cancellations reflect client activities during the period, such as discontinuing products and services and/or reductions in price, resulting in reductions to Run Rate. Net new recurring subscription sales represent the amount of new recurring subscription sales net of subscription cancellations during the period, which reflects the net impact to Run Rate during the period.

Total gross sales represent the sum of new recurring subscription sales and non-recurring sales. Total net sales represent the total gross sales net of the impact from 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, impairment related to sublease of leased property and 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, impairment related to sublease of leased property and 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, including the 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 and, at times, certain other transactions or adjustments, including, when applicable, the impact related to certain acquisition-related integration and transaction costs, the impact from impairment related to sublease of leased property and the impact related to gain from changes in ownership interest of investees.

"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 are invested in securities denominated in currencies other than the U.S. dollar, and accordingly, any such impact is excluded from the disclosed foreign currency-adjusted variances.
