Chevron's third-quarter profit surged by nearly 200% to $9.9 billion, exceeding expectations, driven by high diesel prices that boosted refining margins. Adjusted earnings per share were $5.28, surpassing Wall Street's estimate of $4.89. The refining segment's profit soared over 300% year-over-year to $4.9 billion. Global diesel prices surged due to Ukraine and Iran bombing Russian and Middle Eastern refineries, leading U.S. refineries to increase output to cover supply gaps. Chevron's U.S. refineries operated at near full capacity, and its stock price rose about 2% in pre-market trading.
