Supplements to the Joint Proxy Statement/Prospectus

2The following materials supplement the statements contained in the Joint Proxy Statement/Prospectus and should be read in conjunction with the Joint Proxy Statement/Prospectus and the documents incorporated therein in their entirety. To the extent the information set forth herein differs from or updates information contained in the Joint Proxy Statement/Prospectus, the information set forth herein shall supersede or supplement the information in the Joint Proxy Statement/Prospectus. Nothing in this Current Report shall be deemed an admission of the legal necessity or materiality of the disclosures set forth herein, either separately or taken together. All page references are to pages in the Joint Proxy Statement/Prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the Joint Proxy Statement/Prospectus.

~~SIGNATURES~~The section of the Joint Proxy Statement/Prospectus titled “The Merger–Background of the Merger” is hereby amended and supplemented by amending and restating the first paragraph on page 52 as follows:

In February 2016, Messrs. Robert R. Hill, Jr., South State’s Chief Executive Officer, and James C. Mabry IV, South State’s Executive Vice President, Investor Relations and Mergers & Acquisitions, reached out to Mr. James C. Cherry, Park Sterling’s Chief Executive Officer, regarding South State’s interest in exploring a combination of South State and Park Sterling. Thereafter, during the first half of 2016, the parties engaged in preliminary discussions regarding a potential strategic transaction with the authorization of their respective boards of directors. As part of these preliminary discussions, South State indicated that an important element in a transaction would be the continued role in the combined company of certain members of Park Sterling’s management team, including potentially Mr. Cherry, Donald K. Truslow, Park Sterling’s Chief Financial Officer, Bryan Kennedy, Park Sterling’s President, and Nancy Foster, Park Sterling’s Chief Risk Officer. In connection with these discussions, in early May 2016, Park Sterling formally engaged Stephens as its financial advisor. The parties ultimately did not reach agreement on transaction terms and determined to cease discussions in late May 2016, with the understanding that they would remain in touch in the future.

The section of the Joint Proxy Statement/Prospectus titled “The Merger–Background of the Merger” is hereby amended and supplemented by inserting the following at the end of the penultimate paragraph on page 52:

At this meeting, South State proposed that one Park Sterling director, Mr. Cherry, would be appointed to the South State board of directors and, in a follow-on meeting, Mr. Hill discussed with Mr. Cherry in general terms potential arrangements for Messrs. Cherry, Kennedy and Truslow and that Ms. Foster was not anticipated to have a management role in the combined company.

After the meeting, Mr. Cherry called Mr. Hill to relay the Park Sterling board’s interest in holding further discussions, and communicated the Park Sterling board’s request that South State consider offering another seat on the South State board of directors to a current Park Sterling director to ensure the continued representation of former Park Sterling shareholders on the combined company’s board of directors.

Mr. Hill also communicated to Mr. Cherry that, if the transaction moved forward, South State would be willing to offer a second board seat to a Park Sterling director.

The draft merger agreement provided that Mr. Cherry and one other current member of the Park Sterling board of directors as designated by South State would be appointed to the South State board of directors.

The section of the Joint Proxy Statement/Prospectus titled “The Merger–Background of the Merger” is hereby amended and supplemented by amending and restating the sixth full paragraph on page 54 as follows:

On April 19, 2017, representatives of McGuireWoods provided Wachtell Lipton a revised draft of the merger agreement, which included a provision that Mr. Cherry and one other current member of the Park Sterling board of directors mutually agreed by the parties would be appointed to the South State board of directors. Over the course of the following week representatives of McGuireWoods and Wachtell Lipton exchanged several additional drafts of the merger agreement and related transaction documents, and discussed and negotiated the terms and conditions set forth in the merger agreement and related transaction documents.

The section of the Joint Proxy Statement/Prospectus titled “The Merger–Background of the Merger” is hereby amended and supplemented by inserting the following two paragraphs immediately following the sixth full paragraph on page 54:

On Friday, April 21, 2017, Mr. Hill sent to Mr. Cherry term sheets for a consulting agreement for Mr. Cherry and employment agreements for Messrs. Kennedy and Truslow and communicated that Ms. Foster would not be offered a contract.

On Monday, April 24, 2017, South State provided a draft consulting agreement to Mr. Cherry and draft employment contracts to each of Messrs. Kennedy and Truslow based on the term sheets that had been provided on April 21, 2017. Between April 24 and April 26, Messrs. Cherry, Kennedy and Truslow, on the one hand, and South State, on the other hand, worked to finalize those agreements, which were executed concurrently with the execution of the merger agreement.

The section of the Joint Proxy Statement/Prospectus titled “The Merger—Opinion of Park Sterling’s Financial Advisor—Selected Public Companies Analysis” is hereby amended and supplemented by inserting the following tabular disclosure on page 76 at the beginning of that page:
