S.D. Codified Laws § 47-1A-720
After fixing a record date for a meeting, a corporation shall prepare an alphabetical list of the names of all its shareholders who are entitled to notice of a shareholders' meeting. The list shall be arranged by voting group, and within each voting group by class or series of shares, and show the address of and number of shares held by each shareholder. The shareholders' list shall be available for inspection by any shareholder, beginning two business days after notice of the meeting is given for which the list was prepared and continuing through the meeting, at the corporation's principal office or at a place identified in the meeting notice in the city where the meeting will be held. A shareholder, a shareholder's agent, or an attorney is entitled on written demand to inspect and, subject to the requirements of § 47-1A-1602.3, to copy the list, during regular business hours and at the person's expense, during the period it is available for inspection. The corporation shall make the shareholders' list available at the meeting, and any shareholder, shareholder's agent, or attorney is entitled to inspect the list at any time during the meeting or any adjournment. If the corporation refuses to allow any shareholder, or the shareholder's agent or attorney to inspect the shareholders' list before or at the meeting, or copy the list as permitted by this section, the circuit court of the county where a corporation's principal office is located, or, if none in this state, the circuit court of Hughes County, on application of the shareholder, may summarily order the inspection or copying at the corporation's expense and may postpone the meeting for which the list was prepared until the inspection or copying is complete. Refusal or failure to prepare or make available the shareholders' list does not affect the validity of action taken at the meeting.
