MSCI Inc. announced that it is proposing to issue $250.0 million aggregate amount of senior unsecured notes due 2029 (the “notes”) in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The notes will constitute a further issuance of, be fully fungible with, rank equally with and form a single series with the $500.0 million aggregate principal amount of the 4.000% senior notes due 2029 issued on November 7, 2019. The proposed offering is subject to market and other conditions. If the offering is successfully placed, MSCI intends to use the net proceeds from the offering, together with available cash, for the partial redemption, in an amount equal to the aggregate issue amount of the offering, of its 5.250% senior notes due 2024, of which there is currently $800.0 million aggregate principal amount outstanding. The notes will be senior unsecured obligations of MSCI and will be guaranteed by MSCI and certain of its domestic subsidiaries. The notes are being offered only to (i) persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and (ii) certain non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The notes have not been registered under the Securities Act or any state securities laws and therefore may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws. This press release does not constitute an offer to sell or the solicitation of an offer to buy the notes, nor shall it constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.
