Canadian Natural Resources Limited (CNQ.TO) (CNQ.TO) (“Canadian Natural” or the “Company”) announces that its previously planned Institutional Investor Open House (“Open House”) for June 17, 2015 has been deferred. Rather than the detailed Open House presentation format, a conference call will be held on June 17, 2015, where Investors and Analysts are invited to listen to the Company’s update of its strategy and plans.

The Company maintains a vast portfolio of asset opportunities, a strong balance sheet and a defined, flexible growth plan for each of its products and areas in which it operates. The strategy and plan for a low commodity price environment will be outlined during the conference call. However, due to the current uncertainty surrounding the Government of Alberta’s review of royalty, taxation, environmental and greenhouse gas policies, detailed future capital allocation plans for each of the Company’s assets cannot be finalized at this time. Therefore, the Company will defer the detailed Open House until greater clarity can be attained, to allow for finalization of this capital allocation.

Canadian Natural is a senior oil and natural gas production company, with continuing operations in its core areas located in Western Canada, the U.K. portion of the North Sea and Offshore Africa.
