Why is HF Sinclair Corporation (DINO) stock moving?

DINO closed at $98.76 on Nov 10, down about 21% from $125.25 on Oct 26. The slide began Oct 27, before the Q3 release on Oct 28, then accelerated Nov 4-5 on heavy volume (3.95M and 4.36M shares versus roughly 2M earlier in the month) and closed near the Nov 6 low of $96.07. The fundamental news is strong: Q3 adjusted EPS of $11.75 beat the $7.65 estimate, sales of $10.857B beat $8.893B, refining margins were lifted by tight fuel supply and elevated crack spreads, and management expects Middle East capacity constraints to persist. Morgan Stanley raised its target to $130 on Nov 2 and keeps an Overweight rating. The company is also returning capital: it agreed to buy 2.35M shares from REH at $109.37 (Oct 29) and 2.1M shares at $110.81 (Nov 3), both above the recent trading range. The news flow does not directly explain the sell-off, which suggests the market is pricing in a normalization of refining margins. Price now sits near the $95.56-$97 support zone, and volume has eased to about 2.6M shares, with the last two sessions stabilizing. The Nov 12 ex-dividend date of $0.525 (about 2.1% at current prices) will mechanically reduce the share price slightly. The CEO transition effective Jan 1, 2027 adds a leadership change to watch.

News behind the analysis

About HF Sinclair Corporation

Energy · Oil & Gas Refining and Marketing

HF Sinclair is an independent US petroleum refiner that runs about seven refineries, mostly in the Mid-Continent, Rocky Mountain and Southwest regions, and sells fuel under the green-dinosaur Sinclair brand. It also has businesses in lubricants and specialty products, renewable diesel, and midstream pipelines and terminals, which makes it more diversified than a pure refiner.

How it makes money

Most of its revenue comes from refining crude oil into gasoline, diesel and jet fuel and selling them wholesale and through Sinclair-branded stations. Profit depends mainly on the refining margin, which is the gap between crude costs and fuel prices. Its lubricants and specialty products segment (for example Petro-Canada Lubricants), renewable diesel plants and midstream pipelines and terminals add steadier income. Quarterly revenue in 2026 was roughly $7–11 billion, and refining makes up the large majority of it.
