Strong first half results

2012 Second Quarter Results

In the second quarter of 2012, we generated profit of $189 million compared to record profit of $225 million for the second quarter of 2011. For the six months ended June 30, 2012, we generated profit of $380 million, nearly matching the record profit of $388 million for the six months ended June 30, 2011. The modest declines were primarily due to an increase in depreciation expense and a decline in the mark-to-market values of our open feedstock derivatives, offset slightly during the six month period by higher margins in our Olefins/Polyolefins business unit.

In the second quarter of 2012, our operating activities provided $401 million of cash, compared to $213 million in the second quarter of 2011. In the first half of 2012, our operating activities provided $633 million of cash, compared to $258 million in the first half of 2011. The increases in cash were driven by continued strong earnings and a decrease in working capital.

The Olefins/Polyolefins business unit generated $340 million of operating profit in the second quarter of 2012 versus operating profit of $367 million in the second quarter of 2011. The quarter-over-quarter decline was due to an increase in depreciation expense and lower margins which were partially offset by higher sales volumes. For the six months ended June 30, 2012, the business unit generated operating profit of $648 million, equal to the operating profit for the six months ended June 30, 2011. The Performance Styrenics segment reported operating profit from continuing operations of $1 million in the second quarter of 2012 versus operating profit from continuing operations of $2 million in the second quarter of 2011. For the six months ended June 30, 2012, the segment generated operating profit from continuing operations of $6 million compared to $5 million for the six months ended June 30, 2011. The year-over-year improvement was due to higher expandable polystyrene (“EPS”) margins.

Highlights

In June 2012, we began utilizing ethane/propane (“E/P”) mix as one of the feedstocks for our Corunna cracker. Utilizing E/P feedstock is another crucial step in the diversification of Corunna feedstock sources as we convert the facility to consume up to 100% natural gas liquids.

In May 2012, we announced that we signed a letter of intent with PFB Corporation (“PFB”), for a subsidiary of PFB to acquire NOVA Chemicals’ Performance Styrenics business, including the EPS and ARCEL® resin products. NOVA Chemicals expects to acquire an equity stake in PFB and hold two seats on PFB’s Board of Directors following closing.

Financial Highlights

These highlights should be read in conjunction with our unaudited interim condensed consolidated financial statements, as at and for the period ended June 30, 2012, our other 2012 unaudited interim condensed consolidated financial statements and our annual audited consolidated financial statements as at and for the year ended December 31, 2011 contained in our annual report on Form 20-F.
