Exxon’s stock price has plummeted to a new low.

It is down 7.5 per cent over the past 12 months.

Exxon shares, which had fallen over the summer as tensions over the Middle East heightened, have fallen by nearly half in value since the beginning of 2017.

The company, which is based in Houston, has been hit by a series of scandals including the bribery scandal involving a former top executive.

The US Federal Bureau of Investigation has launched an investigation into the oil giant.

It also alleges that Exxon misled investors about the risks of climate change.

The stock has lost around 60 per cent of its value in the past year.

Exxon CEO Rex Tillerson, who will become president in January, was criticised last week by the company’s chief executive for not taking action to limit global warming.
