South State Corporation has entered into a significant financial agreement involving the issuance of $350 million in subordinated notes. These notes, which will initially bear a fixed interest rate of 7.000% per annum, are scheduled to transition to a floating rate starting June 13, 2030. The floating rate will be determined by the SOFR compounded daily, plus 319 basis points, payable quarterly. The agreement, formalized through an Indenture with U.S. Bank Trust Company as the trustee, outlines semiannual interest payments beginning December 13, 2025, with provisions for redemption by South State Corporation as specified in the Indenture. This financial arrangement was made under the company's effective shelf registration statement, reflecting a strategic move to manage its financial obligations efficiently.
