Suncor Energy announces Normal Course Issuer Bid

Suncor Energy announces Normal Course Issuer Bid 
CALGARY, ALBERTA -- (Marketwire) -- 09/17/12 -- Suncor announced
today that the Toronto Stock Exchange (TSX) has accepted the notice
filed by Suncor of its intention to commence a Normal Course Issuer
Bid (the Bid) through the facilities of the TSX, New York Stock
Exchange and/or alternative trading platforms. The notice provides
that Suncor may, commencing September 20, 2012 and ending September
19, 2013, purchase for cancellation up to $1 billion worth of its
common shares.  
The actual number of common shares that may be purchased and the
timing of any such purchases will be determined by Suncor. All
purchases are expected to be made from existing cash. All common
shares acquired by Suncor under the Bid will be cancelled.  
Suncor believes that, depending on the trading price of its common
shares and other relevant factors, purchasing its own shares
represents an attractive investment opportunity and is in the best
interests of the company and its shareholders.  
Between September 6, 2011 and September 5, 2012, and pursuant to
Suncor's previously announced Normal Course Issuer Bid, Suncor
successfully completed the purchase of $1.5 billion worth of its
common shares (50,160,465), at a weighted average price of $29.90 per
common share. 
Pursuant to the Bid, Suncor has agreed that it will not purchase more
than 38,392,005 common shares, being approximately 2.5% of its
1,535,680,218 issued and outstanding common shares as at September
14, 2012. In addition, and subject to the 'block purchase' exemption,
Suncor will not acquire through the facilities of the TSX more than
25% of the average daily trading volume of its common shares during a
trading day on the TSX, being 903,755 common shares.
