Imperial announces estimated second quarter financial and operating results

For the six months ended June 30, 2014

Calgary, July 31, 2014

Rich Kruger, Chairman, President and Chief Executive Officer, commented:

Imperial’s second quarter results reflect its consistent focus on base business fundamentals as well as profitable and responsible growth. Highlights include strong operational results across Downstream and Chemical and the safe, successful completion of a major turnaround at the Upstream’s Cold Lake Mahihkan facility. In addition, progress continued as planned on the company’s upstream growth projects, Kearl and Nabiye.

Earnings in the second quarter were $1,232 million, or $1.45 per share, and included a $478 million gain associated with the sale of interests in several conventional upstream producing assets.

Gross production averaged 287,000 oil-equivalent barrels per day, up 11,000 barrels versus 2013, due to increased Kearl production, largely offset by planned and unplanned maintenance at Syncrude, major turnaround activities at Cold Lake and the impact of divested conventional assets. Kearl production averaged 73,000 barrels per day (52,000 barrels Imperial’s share) in the quarter, as a significant ramp-up in production in June was offset by planned maintenance and reliability improvement repairs earlier in the quarter.

Refinery throughput totalled 418,000 barrels per day, up 54,000 barrels versus 2013, adjusted for the Dartmouth refinery shutdown. A strong focus on reliability resulted in record refinery capacity utilization of 99 percent. Petroleum product sales of 481,000 barrels per day were up five percent versus the same period last year.

Second quarter capital and exploration expenditures totalled $1,398 million. Investments were primarily associated with upstream growth; most notably the Kearl expansion and Cold Lake Nabiye projects, which were 90 and 89 percent complete, respectively, at the end of the quarter. Expenditures were fully funded from cash flow from operations and proceeds from the divestment of conventional upstream assets.

A major milestone was reached in the quarter when employees moved into the first of five buildings at Imperial’s new Calgary offices in Quarry Park. The campus-style complex, scheduled for full occupancy in early 2016, will facilitate enhanced collaboration and innovation to support the company’s long-term, profitable growth.

After more than a century, Imperial continues to be an industry leader in applying technology and innovation to responsibly develop Canada’s energy resources. As Canada’s largest petroleum refiner, a major producer of crude oil and natural gas, a key petrochemical producer and a leading fuels marketer from coast to coast, our company remains committed to the highest standards across all areas of our business.

Second quarter highlights

Second quarter 2014 vs. second quarter 2013

The company’s net income for the second quarter of 2014 was $1,232 million or $1.45 per share on a diluted basis, compared with $327 million or $0.38 per share for the same period last year.

Upstream net income in the second quarter was $857 million, $460 million higher than the same period of 2013. Earnings in the second quarter of 2014 included a gain of $478 million from the divestment of conventional upstream producing assets. Earnings were also higher by about $70 million due to the impact of a weaker Canadian dollar and higher bitumen realizations of about $55 million. These factors were partially offset by higher royalty costs of about $70 million. The incremental contribution of Kearl production in the second quarter was essentially offset by lower Syncrude and Cold Lake volumes.

The company’s average realizations from the sales of synthetic crude oil increased about 11 percent in the second quarter of 2014 to $111.95 per barrel versus $100.97 per barrel in the second quarter of 2013. The increased realizations reflected increases in West Texas Intermediate (WTI) crude oil benchmark price, which was up about nine percent, and the impact of a weaker Canadian dollar. The company’s average bitumen realizations in Canadian dollars in the second quarter were $75.92 per barrel versus $65.66 per barrel in the second quarter of 2013 as the price spread between light crude oil and bitumen narrowed. The company’s average realizations on natural gas sales of $4.08 per thousand cubic feet in the second quarter of 2014 were higher by $0.58 per thousand cubic feet versus the same period in 2013.

Gross production of Cold Lake bitumen averaged 138,000 barrels per day in the second quarter, down from 144,000 barrels in the same period last year. Lower volumes were primarily due to planned maintenance activities at the Mahihkan facilities. The planned maintenance activities were completed and the plant returned to normal operations at the beginning of the third quarter.

Gross production from the Kearl initial development in the second quarter was 73,000 barrels per day (52,000 barrels Imperial’s share) up from 70,000 barrels per day (50,000 barrels Imperial’s share) during the first quarter of 2014. April production was significantly lower than the quarterly average due to planned maintenance and reliability improvement repairs. Production growth resumed throughout the rest of the quarter, averaging 85,000 barrels per day (60,000 barrels Imperial’s share) in June.

The company’s share of Syncrude’s gross production in the second quarter was 51,000 barrels per day, down from 68,000 barrels in the second quarter of 2013. Higher planned and unplanned maintenance activities were the main contributor to the lower production. The maintenance activities were completed and one of the impacted coker units returned to normal operations during the quarter while the second impacted coker unit returned to normal operations at the beginning of the third quarter.

Gross production of conventional crude oil averaged 18,000 barrels per day in the second quarter, versus 22,000 barrels in the corresponding period in 2013. On May 1, 2014, the company completed the sale of its interests in conventional oil and gas assets located in Boundary Lake, Cynthia/West Pembina and Rocky Mountain House in western Canada. The lower production volume was primarily the impact of divested properties.

Gross production of natural gas during the second quarter of 2014 was 158 million cubic feet per day, down from 204 million cubic feet in the same period last year, reflecting the impact of divested properties.

Downstream net income was $366 million in the second quarter, $463 million higher than the second quarter of 2013. Earnings in the second quarter of 2013 included a charge of $264 million associated with the conversion of the Dartmouth refinery to a fuels terminal. Earnings also increased due to the impacts of improved refinery reliability of about $120 million while higher marketing margins and sales volumes contributed some $70 million.

Chemical net income was $57 million in the second quarter, up from $42 million in the same quarter in 2013. The second quarter 2014 earnings were the best quarterly earnings on record. Higher polyethylene sales volumes and margins were the main contributors to the increase.

Second quarter 2014 vs. second quarter 2013 (continued)

Net income effects from Corporate and Other were negative $48 million in the second quarter, versus negative $15 million in the same period of 2013, primarily due to changes in share-based compensation charges.

The company’s cash balance was $171 million as at June 30, 2014 versus $102 million at the end of the first quarter of 2014.

Cash flow generated from operating activities was $999 million in the second quarter, versus $738 million in the corresponding period in 2013. Higher cash flow was primarily due to higher earnings partially offset by working capital effects.

Investing activities used net cash of $595 million in the second quarter, compared with $1,562 million in the same period of 2013. Additions to property, plant and equipment were $1,295 million in the second quarter, compared with $1,616 million during the same quarter in 2013. Expenditures during the quarter were primarily directed towards the advancement of Kearl expansion and Cold Lake Nabiye projects.

Proceeds from asset sales were $732 million in the second quarter, primarily related to the sale of conventional upstream producing assets, compared with $54 million in the second quarter of 2013.

Cash used in financing activities was $335 million in the second quarter, compared with cash from financing activities of $1,043 million in the second quarter of 2013. In the second quarter, the company reduced the level of its short-term debt by redeeming $223 million of its outstanding commercial paper. Dividends paid in the second quarter of 2014 were $110 million, $8 million higher than the corresponding period in 2013. Per-share dividend paid in the second quarter was $0.13, up from $0.12 in the same period of 2013.

Six months highlights

Six months 2014 vs. six months 2013

Net income in the first six months of 2014 was $2,178 million, of $2.56 per share on a diluted basis, versus $1,125 million of $1.32 per share for the first half of 2013.

Upstream net income for the first six months of 2014 was $1,309 million, $612 million higher than the same period of 2013. Earnings in 2014 included a gain of $478 million from the divestment of conventional upstream producing assets. Earnings also increased due to higher liquids realization of about $250 million and the impact of a weaker Canadian dollar of about $155 million. These factors were partially offset by higher royalty costs of about $165 million and higher energy costs of about $55 million. The incremental contribution of Kearl production was essentially offset by lower Syncrude and Cold Lake volumes.

The company’s average realizations from the sale of synthetic crude oil increased about 11 percent in the first six months of 2014 to $108.76 per barrel versus $98.39 per barrel in the corresponding period last year. The increased realizations reflected the increase in the WTI crude oil benchmark price, which was up about seven percent, and the impact of a weaker Canadian dollar. The company’s average bitumen realizations in Canadian dollars for the six months year-to-date in 2014 were $70.79 per barrel versus $54.03 per barrel in the same period in 2013 as the price spread between light crude oil and bitumen narrowed. The company’s average realizations on natural gas sales of $5.49 per thousand cubic feet in the first six months of 2014 were higher by $1.99 per thousand cubic feet versus the same period in 2013.

Gross production of Cold Lake bitumen averaged 142,000 barrels per day in the first six months, down from 154,000 barrels from the same period last year. Lower volumes were primarily due to the cyclic nature of steaming and associated production and the impacts of several unplanned third-party power outages in the first quarter and planned maintenance activities in the second quarter.

Gross production from the Kearl initial development in the first six months of 2014 was 72,000 barrels per day (51,000 barrels Imperial’s share).

During the first six months of 2014, the company’s share of gross production from Syncrude averaged 62,000 barrels per day, down from 67,000 barrels from the same period of 2013. Higher maintenance activities were the main contributor to the lower volumes.

Gross production of conventional crude oil averaged 20,000 barrels per day in the first half of 2014, unchanged from the same period in 2013.

Six months 2014 vs. six months 2013 (continued)

Gross production of natural gas during the first six months of 2014 was 181 million cubic feet per day, down from 195 million cubic feet in the same period last year. The lower production volume was primarily the impact of divested properties.

Downstream net income was $854 million, up $473 million in the same period of 2013. Earnings in the first half of 2013 included a charge of $264 million associated with the conversion of the Dartmouth refinery to a fuels terminal. Earnings also increased due to the impacts of improved refinery reliability of about $220 million, higher marketing margins and sales volumes totaling about $85 million and a weaker Canadian dollar of about $50 million. These factors were partially offset by lower industry refining margins of about $150 million.

Chemical net income was $100 million, the best first six months earnings on record and up $23 million over the same period in 2013. Higher margins across all major product lines and higher polyethylene sales volumes were the main contributors to the increase.

For the six months of 2014, net income effects from Corporate & Other were negative $85 million, versus negative $30 million in 2013, primarily due to changes in share-based compensation charges.
