Exxon earnings for the April-June period came to $3.95 billion, or 81 cents a share. That was down from $11.68 billion, or $2.22 a share, a year ago, a record at the time. Revenue fell 46 percent to $74.5 billion from $138.1 billion a year ago. Analysts, on average, had forecast revenue of about $71.3 billion, Thomson Reuters said.

The substantial profit falloff was no surprise given the steep drop in oil and natural gas prices from a year ago. Major integrated oil companies ConocoPhillips, BP and Royal Dutch Shell already have reported that profits fell between 53 percent and 67 percent in the second quarter.
