TORONTO, April 30 /CNW/ - CIBC (CM: TSX; NYSE) announced today that the
Toronto Stock Exchange (TSX) accepted notice of CIBC's intention to commence a
normal course issuer bid. On April 27, 2007, CIBC announced that, subject to
TSX approval, it may purchase for cancellation, from time to time until
October 31, 2007, up to an aggregate of 10,000,000 common shares, representing
approximately 3% of CIBC's public float of 335,250,696 common shares as at
April 24, 2007.
    CIBC's repurchase of common shares under a normal course issuer bid is
consistent with the bank's priority of maintaining balance sheet strength,
while generating shareholder value through a balanced capital deployment
strategy.
    Purchases under this new bid may commence on the TSX and the New York
Stock Exchange on May 2, 2007 and will conclude on the earlier of the
termination of the bid, the date on which purchases under the bid have been
completed, or October 31, 2007. The expiry date of October 31, 2007 will
enable CIBC to align this and potential future share repurchase programs with
its fiscal reporting period.
    As at April 24, 2007, CIBC had 337,533,027 issued and outstanding common
shares.
