On March 27, 2018, the shareholders of Stellar Biotechnologies, Inc. (the “Company”) approved at the Company’s Annual Meeting (as defined below under Item 5.07) the alteration of the Company’s Notice of Articles and Articles to create a class of Preferred Shares, consisting of an unlimited number of Preferred Shares, without par value. The Preferred Shares may be designated and issued in one or more series in the future, with such rights, preferences and privileges as determined by the Board of Directors, if and when issued, without further shareholder action. The authorized share increase will not change the number of common shares currently outstanding, nor will it have any immediate dilutive effect or change the rights of current holders of our common shares. However, to the extent that Preferred Shares are issued in the future, they may dilute the percentage equity ownership of existing shareholders and, depending on the price at which they are issued, may also dilute earnings and book value on a per share basis. Preferred Shares, if and when issued, may or may not have a dilutive effect on the voting rights of shareholders owning common shares, depending on the rights and preferences set by the Board. However, except for such rights relating to the election of directors, or on a default in payment of dividends as may be attached to any series of the Preferred Shares by the Board of Directors, or in connection with convertible Preferred Shares, the holders of Preferred Shares shall not be entitled as such to receive notice or, to attend or to vote at any general meeting of shareholders of the Company.
