It is also an admission of how profound the change in the oil and gas business has been. A dozen years ago, ExxonMobil set new profit records and was the envy of the market. Now, the company is no longer in the top tier. Microsoft is worth nine times as much, and Johnson & Johnson is worth twice as much in market value. ExxonMobil, which supplies gasoline to automobiles, is worth $180 billion, not even two-thirds the market value of Tesla, the maker of electric vehicles.
