MSCI Inc SEC Filings

MSCI Inc. furnished third‑quarter financial information for the period ended September 30, 2025 via a press release attached as Exhibit 99.1. The release includes non‑GAAP measures with definitions and GAAP reconciliations.

Separately, on October 25, 2025, the Board authorized a new share repurchase program for up to $3.0 billion of common stock, which supersedes and replaces the prior program authorized on October 28, 2024. Repurchases may occur from time to time in open‑market or privately negotiated transactions, including accelerated share repurchases, trading plans, or derivative transactions. The timing, price and amount will depend on market conditions, capital resources, applicable laws and other factors, and the authorization may be modified, suspended or terminated at any time.

MSCI updated its 2025 interest expense outlook after issuing $1.25 billion of 5.25% senior notes due 2035 and repaying borrowings under its revolving credit facility on August 11, 2025. The company now expects full-year 2025 interest expense (including amortization of financing fees) of approximately $205 to $209 million, up from prior guidance of $182 to $186 million. For the quarter ending September 30, 2025, MSCI currently expects interest expense of approximately $54 to $55 million.

The company attributes the change to the August 2025 issuance and the resulting higher expected debt balance for 2025. Other components of its previously issued full-year 2025 guidance remain unchanged. MSCI notes its guidance depends on macroeconomic and capital markets assumptions and warns actual results could differ materially.
