CALGARY, ALBERTA (December 10, 2012) — MEG Energy Corp. ("MEG") reported today
that it has entered into agreements to offer a total of 24,246,212 MEG common shares at a
price of CDN$33.00 per share to raise gross proceeds of approximately CDN$800 million.
Under the agreements, 12,125,000 MEG common shares will be issued on a bought deal basis
through a syndicate of underwriters co-led by BMO Capital Markets, Credit Suisse Securities
(Canada), Inc., Barclays Capital Canada Inc. and RBC Capital Markets (the "Public Offering").
An additional 12,121,212 MEG common shares will be issued on a private placement basis at
the same price of CDN$33.00 per share to Caisse de dépôt et placement du Québec (the
"Caisse"), an existing shareholder of MEG (the "Private Placement"). Completion of the Public

Public Offering of Common Shares

Under the Public Offering, the underwriters will purchase 12,125,000 MEG common shares for
proceeds of approximately CDN$400 million. MEG has also granted the underwriters an overallotment
option to purchase, on the same terms, up to an additional 1,818,750 MEG common
shares for proceeds of up to approximately $60 million. This option is exercisable, in whole or in
part, by the underwriters at any time up to 30 days after closing. If the over-Allotment Option is
exercised in full, the gross proceeds raised under the Public Offering will be approximately
CDN$460 million. Closing is expected to occur on or about December 28, 2012, and is subject
to customary regulatory approvals, including the approval of the Toronto Stock Exchange. The
Public Offering will be an underwritten, bought deal public issue in all provinces and territories of
Canada by way of a short form prospectus. This offering will also be extended to Qualified
Institutional Buyers in the United States, pursuant to the registration exemptions provided by
Rule 144A of the Securities Act of 1933 and internationally, as permitted.

MEG and the Caisse have entered into a binding agreement, pursuant to which the Caisse will

approximately $400 million. Closing of the Private Placement is expected to occur on or about
December 28, 2012, concurrent with the closing of the Public Offering. Upon closing, the Caisse
will be entitled to a non-refundable capital commitment payment equal to 1% of the aggregate
purchase price for the Placement Shares. Assuming completion of the Private Placement and

Placement Shares will be subject to a four month statutory hold period. BMO Capital Markets
