HF Sinclair beats quarterly profit estimates

July 28 (Reuters) - Refiner HF Sinclair DINO.N beat Wall Street estimates for second-quarter adjusted profit on Tuesday, helped by higher refining margins as ongoing tensions in the Middle East boosted demand for U.S. fuel exports.

The Dallas, Texas-based company reported adjusted profit of $5.31 per share for the three months ended June 30, compared with analysts' average estimated loss of $4.51 per share, according to data compiled by LSEG.
