Exxon Mobil and Chevron on Friday reported their lowest second-quarter profits in four years, as lower global energy prices and a surge in oil supply from OPEC+ weighed on revenues. However, both US oil giants still managed to beat Wall Street's earnings expectations, driven by higher production volumes. Texas-based Exxon Mobil posted a net profit of $7.08 billion, or $1.64 per share, for the quarter ended June 30, down from $9.24 billion, or $2.14 per share, in the same period last year. Revenue dropped to $81.51 billion from $93.06 billion, missing analyst projections of $82.82 billion, according to Zacks Investment Research, AP reporyted. Exxon does not adjust its earnings for one-time items, such as asset sales. Still, its reported profit exceeded analysts' average forecast of $1.49 per share.
