Exxon Mobil has said its first quarter profits rose 38% from the same period a year earlier to $6.3 billion.
The profits excluded a $200m charge to pay for changes in US healthcare legislation. Amid high oil prices of around $85 a barrel, Exxon had been expected by analysts to report slightly stronger.
In 2009 Exxon recorded the largest profit of any publicly-listed company in the world, a whopping $40.6 billion, boosted by record high oil prices.
The Texas-based company said oil production increased around 4.5% in the first quarter compared with the same period a year ago.
