Exxon Mobil Inc. shares slid 1.5% in premarket trade Friday, after first-quarter profit fell short of estimates. The oil giant said it had net income of $4.650 billion, or $1.09 a share, in the quarter, up from $4.101 billion, or 95 cents a share, in the year-earlier period. Revenue rose to $68.211 billion from $58.671 billion. The FactSet consensus was for EPS of $1.10 and revenue of $67.201 billion. Oil-equivalent production was 3.9 million barrels a day, down 6% from the year-earlier quarter. Chief Executive Darren Woods said higher commodity pries and cost cuts helped drive growth. “Through new discoveries and acquired acreage, we’ve positioned our Upstream portfolio well for future growth,” he said in the earnings release. “We also made good progress on our plans to improve the production mix and grow premium product sales in the Downstream and Chemical businesses.” Shares are down 0.5% in the last 12 months, while the Dow Jones Industrial Average has gained 16% and the S&P 500 has gained 12%.
