Suncor Energy Delivers Record Quarterly Results

Plans established for company’s next stage of growth

All financial figures are unaudited and in Canadian dollars unless noted otherwise. Natural gas converts to barrels of oil equivalent at a 6:1 ratio (six million cubic feet of natural gas converts to one thousand barrels of oil equivalent).

Calgary, Alberta – Suncor Energy Inc. released its first quarter 2003 results today, reporting record earnings and cash flow. Net earnings for the quarter were $368 million ($0.84 per common share), up from $90 million ($0.18 per common share) in the first quarter of 2002. Excluding the effects of unrealized foreign currency translation gains on the company’s U.S. dollar denominated long-term debt and preferred securities, 2003 first quarter net earnings were $324 million ($0.69 per common share). Cash flow from operations was $613 million for the quarter, compared to $181 million in the first quarter of 2002.

The record quarterly financial performance was primarily the result of higher crude oil and natural gas prices, higher year-over-year oil sands production and improved refining and retail margins. Suncor’s total production for the quarter averaged 245,600 barrels of oil equivalent (BOE) per day, up from the 212,300 BOE per day average recorded in the first quarter of 2002. Suncor’s oil sands operations generated the largest part of this total, with first quarter production averaging 211,100 barrels per day, compared to 179,300 barrels per day in the first quarter of 2002.

“Suncor’s strategy is about profitability throughout the price cycle,” said Rick George, president and chief executive officer. “To stay on that track, we will continue to focus on reducing costs, increasing production and reducing debt, while building the foundation for future growth.”

Effective January 2003, Suncor revised its definitions of cash and total operating costs. These revised definitions report only those costs directly related to producing a barrel of oil from oil sands during the current period, including natural gas and imported bitumen costs. To enable comparison, cash operating costs under the previous definition are included in brackets. For full details, see page 18 of Suncor’s quarterly Report to Shareholders.

Cash operating costs averaged $12.40 ($14.95) per barrel for the first quarter of 2003, compared to the $10.20 ($12.50) per barrel average in the fourth quarter of 2002. The increase reflects higher natural gas costs and lower than expected production, which was hampered by extremely cold winter weather.

The impact of high natural gas prices has resulted in Suncor adjusting its cash operating cost target for the year. Suncor currently expects its cash operating costs to average $11.25 to $11.75 ($13.50 to $14.00) per barrel in 2003. Because Suncor’s natural gas production exceeds internal consumption, the net impact to the company of high gas prices is positive.

On April 3, Suncor announced plans to spend an estimated total of $3 billion to further boost production capacity at its oil sands facility to 330,000 barrels per day by late 2007. The production increase calls for expansion of the company’s oil sands upgrading facilities and development of additional stages of the Firebag In-situ Oil Sands Project.

To manage the marketing of its increased production, Suncor is investigating options that would enable sour crude blends from its oil sands operation to be processed at the company’s Sarnia refinery. This proposed work would be combined with modifications to meet pending diesel desulphurization requirements. A decision on whether to proceed with the sour crude modifications is expected in 2004 and would be subject to approval from regulators and Suncor’s Board of Directors.

The Sarnia refinery modifications would complement Suncor’s recently announced plans to acquire a refinery and related assets in Colorado from ConocoPhillips. Suncor will pay US$150 million (Cdn$220 million) for the assets with a further investment of US$175 million to $225 million (Cdn$260 million to $330 million) to meet new fuels regulations and enable the refinery to integrate some Suncor sour crude blends. The purchase, which is expected to close in August, is subject to a number of conditions including approval of the U.S. Federal Trade Commission and other regulatory authorities.

“Our strategy is to directly connect our increasing crude oil production to markets with growing demand — the Sarnia and Denver refineries provide that connection,” said George. “Our plans for the downstream in Canada and the U.S. are a good fit in terms of flexibility to handle different crude products and timing that coincides with our oil sands growth plan.”

Suncor continues to reduce its debt as the company prepares for future growth. Excluding the effects of unrealized foreign exchange gains, Suncor’s debt stood at $2.4 billion at March 31, 2003, a reduction of approximately $270 million from December 31, 2002. Suncor continues to target its debt level at approximately two times cash flow at mid-cycle oil prices.

* Production at Suncor’s oil sands operation will be lower than capacity as a result of a 30-day maintenance shutdown on Upgrader #1.

** Operating, selling and general production costs (excluding inventory changes), taxes other than income taxes and the cost of bitumen imported from third parties, divided by production volumes.

*** Operating, selling and general sales costs (including inventory changes), start-up costs, cost of imported bitumen and cash overburden spending divided by sales volumes.

Factors that could potentially impact the second quarter of 2003 include:

•		Ongoing volatility in crude oil markets and North American natural gas markets.

•		Price realization on crude oil sales, which can be impacted by Suncor’s sales mix as well as general market conditions that impact sour crude oil and bitumen price differentials.

•		Delays or unforeseen issues related to the 30-day maintenance shutdown scheduled to begin May 19.

•		Refining margins, which are currently between 5.7 cents per litre (cpl) and 5.9 cpl, compared to 7.8 cpl in the first quarter of 2003; retail margins, which are currently between 6.8 cpl and 7.0 cpl, compared to 7.0 cpl in the first quarter of 2003.

•		Proposed changes to taxation of the resource sector in Canada and planned reductions in Alberta provincial income tax rates. (See Suncor’s first quarter 2003 Management’s Discussion and Analysis for further details.)
