Exxon mobile refinery

Exxon Mobil reported quarterly earnings that beat analysts estimates, but fell 38 percent from the year-ago period as low oil prices cut into the company's exploration and production segment and refining margins continued to contract.

"Exxon Mobil's integrated business continues to deliver solid results," Rex W. Tillerson, Exxon chairman and CEO, said in a statement. "While the operating environment remains challenging, the company continues to focus on capturing efficiencies, advancing strategic investments and creating long-term shareholder value."
