SouthState (SSB) said Thursday it closed the acquisition of Independent Bank Group (IBTX) on Jan. 1.

Florida-based SouthState said in May that it had agreed to acquire Independent Bank Group in an all-stock transaction valued at about $2 billion.

In connection with the acquisition, SouthState said it was increasing the size of its board, and that of SouthState Bank, to 15 members from 12 with the appointment of three new members.
