Canadian Oil Sands Reports Over $1 Billion of Cost Savings Achieved at Syncrude Year to Date

CALGARY, AB--(Marketwired - October 29, 2015) - All financial figures are unaudited, have been prepared in accordance with Canadian Generally Accepted Accounting Principles ("GAAP") and are reported in Canadian dollars, unless otherwise noted.

Canadian Oil Sands Limited (TSX: COS) (OTCQX: COSWF) ("COS") reported cash flow from operations of $82 million, or $0.17 per Share, in the third quarter, reflecting a 41 percent decline in our realized selling price and reduced production volumes, offset by significant cost reductions at Syncrude.

"The Syncrude project is entering a new era of lower cost operations. A major period of reinvestment that will sustain production for decades has come to a close and Syncrude is driving down costs in its base operations," said Ryan Kubik, President and Chief Executive Officer. "Canadian Oil Sands is demonstrating its ability to weather this period of low oil prices and even a modest improvement in oil prices will generate robust expansion of cash flow."

Canadian Oil Sands has a strong balance sheet and ample financial flexibility. Net debt has declined over the previous quarter, and the earliest long-term debt maturity is not until 2019.

The COS Board of Directors has reviewed the Suncor Energy Inc. bid with its external financial and legal advisors and has determined that the bid substantially undervalues COS and is not in the best interests of COS and its shareholders. The Board unanimously recommends shareholders reject this undervalued, opportunistic, and exploitive bid as discussed further below.

Highlights for the three months ended September 30, 2015:

• Results in the third quarter reflect two months of strong operations, with production averaging about 320,000 barrels per day (117,600 barrels per day net to COS) and operating expenses of approximately $30 per barrel in July and August; however, in late August, a process fire occurred in a section of piping at Syncrude's upgrader, which limited SCO shipments to minimal levels while damage was being assessed and facilities were being repaired. The incident resulted in a production impact of approximately seven million barrels (2.6 million barrels net to COS) in the quarter.
• Sales volumes averaged 86,687 barrels per day relative to the 87,787 barrels per day recorded in the third quarter of 2014.
• Operating expenses fell $7.24 per barrel, averaging $40.49 per barrel compared with the same 2014 period. The decline reflects progress on Syncrude's cost reduction initiatives, partially offset by the impact of the process fire on production volumes.
• Capital expenditures were down 62 percent to $84 million compared with the 2014 third quarter, reflecting completion of Syncrude's major projects and progress on cost reduction initiatives. The Centrifuge Tailings Management project was completed approximately $100 million ($37 million net to COS) under budget.
• Syncrude achieved more than $1 billion ($367 million net to COS) in operating and capital cost reductions in the first nine months of 2015. As a result of significant progress on cost reduction initiatives, Syncrude has increased its targeted savings for 2015 to $1.3 billion ($488 million net to COS).
• COS realized a SCO selling price of $60.20 per barrel compared with $102.58 per barrel in the same 2014 quarter.
• Cash flow from operations was $82 million ($0.17 per Share) compared with $302 million ($0.62 per Share) in the same quarter of 2014, largely reflecting a lower realized SCO selling price partially offset by lower operating costs.
• COS reported a net loss of $174 million ($0.36 per Share) for the quarter, mainly reflecting unrealized foreign exchange losses on the revaluation of U.S. dollar denominated long-term debt.
• COS declared a quarterly dividend of $0.05 per Share, payable on November 30, 2015 to shareholders of record on November 23, 2015.

Syncrude Operations

During the third quarter of 2015, Syncrude produced 21.6 million barrels, or 234,500 barrels per day, compared with 22.5 million barrels, or 244,800 barrels per day, in the third quarter of 2014. Production during the third quarter of 2015 was impacted by a process fire in the interconnecting piping between the hydrotreating and environmental units at Syncrude's upgrader which limited SCO shipments to minimal levels while damage was being assessed and the facilities were being repaired. The incident did not result in any injuries and the mining and extraction operations and major upgrading units were not damaged. All necessary repairs have now been made and Syncrude is implementing a plan to prevent a similar incident in the future. In the third quarter of 2014, production volumes reflected unplanned outages on sulphur processing units.

On a year-to-date basis, Syncrude produced 66.9 million barrels, or 245,100 barrels per day, in 2015 compared with 67.3 million barrels, or 246,400 barrels per day in 2014.

In September 2015, Syncrude achieved the highest level of certification for the sixth consecutive time in the Progressive Aboriginal Relations (PAR) program from the Canadian Council of Aboriginal Business. The PAR Gold certification recognizes Syncrude's commitment to Aboriginal employment, community investment, business development and community engagement.

Board of Canadian Oil Sands Recommends Rejection of Substantially Undervalued Suncor Bid

On October 5, 2015, Suncor Energy Inc. ("Suncor") announced a bid to acquire all the common shares of Canadian Oil Sands on the basis of 0.25 of a Suncor share for each share of COS. The Board of Directors of COS has now completed a full review of the offer with its external financial and legal advisors and has determined that the Suncor bid substantially undervalues COS and is not in the best interests of COS and its shareholders.

• The value offered for the shares is wholly inadequate; it substantially undervalues the COS ownership in Syncrude.
• Timing of the Suncor bid is entirely opportunistic; it is intended to take advantage of unprecedented conditions in the energy industry.
• The bid is exploitive: As an insider to the Syncrude joint venture, Suncor is aware of several cost reduction and value enhancing initiatives being discussed and implemented at Syncrude. Suncor's offer is attempting to increase its ownership before these initiatives take hold and are recognized and valued by the market.
• The bid fails to recognize that COS is strongly positioned to withstand low oil prices and emerge with even greater value when oil prices recover.

Its financial advisor, RBC Capital Markets, has provided COS' Board of Directors with a written opinion that the consideration offered by the Suncor bid is inadequate to shareholders from a financial point of view.

To ensure the best interests of COS and shareholders are served, the Board of Directors is looking at a full range of strategic alternatives, from continuing as an independent company, to a merger or partnership with a strategic or financial partner, to a sale reflecting full and fair value for Canadian Oil Sands' shareholders.

The Board of Directors and management of COS will not tender to the Suncor bid, and we strongly recommend that all shareholders join us in rejecting this undervalued, opportunistic and exploitive bid.

2015 Outlook

• On October 19, 2015, COS revised its Syncrude production range to between 92 and 97 million barrels with a single-point estimate of 95 million barrels.
• Estimated 2015 operating expenses decreased to $1,416 million, or $40.56 per barrel, and estimated 2015 capital expenditures decreased to $368 million. Syncrude is now targeting cost reductions of $1.3 billion ($488 million net to COS) in 2015, having achieved $1 billion in savings in the first nine months of 2015.
• Our estimate of cash flow from operations decreased to $340 million, or $0.70 per Share, mainly reflecting lower assumed production and realized SCO selling price, partially offset by lower estimated operating and capital costs.
• The estimated 2015 realized SCO selling price was decreased to approximately $62 per barrel, reflecting a U.S.$50 per barrel WTI oil price, a $0.79 $US/$Cdn foreign exchange rate, and a $1.25 per barrel SCO discount to WTI.

Canadian Oil Sands expects to release its budget for 2016 in early December, which will include an outlook for Syncrude production and costs.
