TORONTO, ONTARIO--(Marketwired - April 12, 2013) - Onex Corporation ("Onex") (TSX:OCX) announced today that it has filed with the Toronto Stock Exchange, and the Exchange has accepted, a Notice of Intention to make a Normal Course Issuer Bid permitting Onex to purchase for cancellation up to 10% of the public float in its Subordinate Voting Shares, or 8,874,849 shares. There are 113,952,935 Subordinate Voting Shares issued and outstanding and the public float as at March 31, 2013 was 88,748,496 shares.

Onex may buy back shares from time to time during the next twelve months. Any purchases made under the Normal Course Issuer Bid will be effected through the facilities of the Exchange. Onex commenced a similar bid on April 16, 2012, which expires on April 15, 2013 and under which a total of 1,526,865 Subordinate Voting Shares have been purchased as at April 4, 2013 at an average purchase price of C$42.35 per share.

The Normal Course Issuer Bid is being renewed as it is Onex' view that it is advantageous to the company and its shareholders to continue to engage in repurchases of Subordinate Voting Shares, from time to time, when they are trading at prices which reflect a discount from their value as perceived by Onex.
