Suncor Energy (SU) reports its second-quarter results on August 4, and the quarter should be exceptional. WTI averaged approximately US$95.65 per barrel from April through June, while refining margins reached levels exceeded only twice before, both in 2022.

I estimate adjusted funds from operations of approximately C$5.6 billion, compared with the C$5.345 billion Suncor generated in the second quarter of 2022. My estimate falls within a relatively wide range of C$5.2 billion to C$5.9 billion, but anything above the low end would likely represent a record.

That result will generate substantial cash for debt reduction, dividends, and share repurchases. However, a single strong quarter does not determine Suncor’s intrinsic value. The more important question is how much of the company’s current earnings power should be incorporated into a normalized estimate of cash flow.

I last valued Suncor’s TSX-listed shares at C$70 in December, when they traded near C$60. That estimate assumed US$65-per-barrel WTI over the longer-term due to the outlook for a sustained oversupply. It also assumed refining margins modestly above management’s guidance. The shares have since appreciated sharply, closing at C$87.53 on July 16.

I now believe Suncor’s normalized earnings power is higher than my December estimate. However, the change is attributable to the macro outlook and not any structural change in Suncor’s earning power.
