SDCL § 47-1A-1606: Exception to notice requirement.

Whenever notice is required to be given under any provision of this chapter to any shareholder, such notice may not be required to be given if:

(1) Notice of two consecutive annual meetings, and all notices of meetings during the period between such two consecutive annual meetings, have been sent to such shareholder at such shareholder's address as shown on the records of the corporation and have been returned undeliverable; or

(2) All, but not less than two, payments of dividends on securities during a twelve-month period, or two consecutive payments of dividends on securities during a period of more than twelve months, have been sent to such shareholder at such shareholder's address as shown on the records of the corporation and have been returned undeliverable.

If any such shareholder shall deliver to the corporation a written notice setting forth such shareholder's then-current address, the requirement that notice be given to such shareholder shall be reinstated.
