S.C. Code Ann. § 35-2-111

(a) Unless otherwise provided in a corporation's articles of incorporation or bylaws before a control share acquisition has occurred, in the event control shares acquired in a control share acquisition are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of all voting power, all shareholders of the issuing public corporation have dissenters' rights to receive fair value for their shares as provided in this article. (b) As soon as practicable after these events have occurred, the board of directors shall cause a notice to be sent to all shareholders of the corporation advising them of the facts and that they have dissenters' rights to receive the fair value of their shares. (c) As used in this section, 'fair value' with respect to a dissenter's shares, means the value of the shares immediately before the effectuation of the corporate action to which the dissenter objects, excluding any appreciation or depreciation in anticipation of the corporate action to which the dissenter objects, excluding any appreciation or depreciation in anticipation of the corporate action unless exclusion would be inequitable. The value of the shares is to be determined by techniques that are accepted generally in the financial community, except that this value may not be less than the highest price paid per share by the acquiring person in the control share acquisition.
