Articles of Amendment

In addition to the annual election of directors, appointment of Celestica’s auditors (and authorization of the directors to fix their remuneration), and an executive compensation advisory vote, shareholders will be asked at the Meeting to consider and, if thought advisable, pass a special resolution approving an amendment to the Corporation’s articles of incorporation to, among other things, (a) eliminate multiple voting shares as an authorized class of shares of the Corporation, and (b) redesignate the subordinate voting shares as common shares.
