Wis. Stat. § 180.0624
Unless the articles of incorporation provide otherwise before the issuance of the rights, options or warrants, a corporation may issue rights, options or warrants for the purchase of shares of the corporation. The rights, options or warrants may contain provisions that adjust the rights, options or warrants in the event of an acquisition of shares or a reorganization, merger, interest exchange, sale of assets or other occurrence. Subject to the articles of incorporation, the board of directors shall determine the terms on which the rights, options or warrants are issued, their form and content, and the consideration for which the shares are to be issued. Notwithstanding s. 180.0601 (1) and any other provision of this chapter, and unless otherwise provided in the articles of incorporation before issuance of the rights, options or warrants, a corporation may before, on or after April 30, 1972, issue rights, options or warrants that include conditions that prevent the holder of a specified percentage of the outstanding shares of the corporation, including subsequent transferees of the holder, from exercising those rights, options or warrants.
