Shell on Thursday reported a fourth-quarter profit of $3.66 billion, missing estimates, on lower refining margins and lower liquefied natural gas (LNG) trading, while saying it would buy back shares worth $3.

Shell (NYSE:SHEL) +3.2% in Thursday's trading despite missing Q4 earnings and revenue estimates, weighed by weaker oil and gas prices and demand, but the company increased shareholder returns in a sign of confidence in its strategy of refocusing on its most profitable sectors.

The energy major said profits fell after a year of operating in ‘a lower price environment’, amid shrinking margins from its oil refining business.
