(1) The information set forth in Items 4, 5 and 6 of this statement on Schedule 13D is incorporated herein by reference.

This Amendment No. 1 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D filed on April 13, 2016 (as amended, the “Schedule 13D”) with the Securities and Exchange Commission, relating to the shares of voting common stock, par value $0.01 per share, of HCSB Financial Corporation (the “Company”). The address of the principal executive office of the Company is 3640 Ralph Ellis Boulevard, Loris, South Carolina, 29569. Unless specifically amended hereby, the disclosures set forth in the Schedule 13D remain unchanged.

Item 3. Source and Amount of Funds or Other Consideration

The information in Items 4 and 6 is incorporated by reference.

On April 19, 2017, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with United Community Banks, Inc. (“United”). On July 31, 2017, pursuant to the Merger Agreement, the Company merged with and into United (the “Merger”), whereby United continued as the surviving corporation and the separate existence of the Company ceased.

Prior to the Merger, Castle Creek Capital Partners VI, LP (“Fund VI”) owned (1) 35,968,163 shares of voting common stock, par value $0.01 per share, of the Company (“HCSB Voting Common Stock”) and (2) 74,031,837 shares of non-voting common stock, par value $0.01 per share, of the Company (“HCSB Non-Voting Common Stock”). Pursuant to the Merger Agreement, upon the effectiveness of the Merger, each share of Fund VI’s HCSB Voting Common Stock and HCSB Non-Voting Common Stock was canceled and converted into the right to receive 0.0050 shares of common stock, par value $1.00 per share, of United (“United Common Stock”). Cash was paid in lieu of fractional shares. As a result, Fund VI has no continuing ownership interest in the Company.

The foregoing references to and descriptions of the Merger Agreement, and the transactions contemplated thereby, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the full text of the Merger Agreement (including its amendments), attached hereto as Exhibit 2 and incorporated herein by reference.

Item 4. Purpose of Transaction

The information in Items 3 and 6 is incorporated by reference.

Upon effectiveness of the Merger, the separate corporate existence of the Company ceased. Accordingly, each of the Reporting Persons has no plans or proposals that relate to or would result in any of the events set forth in Items 4(a) through (j) of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Paragraphs (a) and (b) of Item 5 of the Schedule 13D are hereby amended and supplemented, with effect from the date of the event giving rise to this Amendment, by replacing the text in paragraphs (a) and (b) of Item 5 of the Schedule 13D with the following:

The information contained on the cover pages to this Schedule 13D and the information set forth or incorporated in Items 2, 3, 4 and 6 is incorporated herein by reference.

(a) and (b)

(1) As described in Item 3, the separate corporate existence of the Company ceased upon effectiveness of the Merger.

(e)

As of July 31, 2017, the Reporting Persons ceased to be beneficial owners of more than five percent of the HCSB Voting Common Stock.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The information set forth in Items 3 and 4 is incorporated herein by reference.

On April 19, 2017, the Company and United entered into the Merger Agreement. On July 31, 2017, pursuant to the Merger Agreement, the Company merged with and into United, with United continuing as the surviving corporation. Upon the effectiveness of the Merger, each of the 35,968,163 shares of HCSB Voting Common Stock and 74,031,837 shares of HCSB Non-Voting Common Stock previously owned by Fund VI was canceled and converted into 0.0050 shares of United Common Stock. Cash was paid in lieu of fractional shares. As a result, Fund VI has no continuing ownership interest in the Company, and the separate corporate existence of the Company has ceased.
