Royal Dutch Shell has today increased its dividend after easily beating third-quarter profit forecasts even as the energy company warned of "significant uncertainty" because of the Covid-19 pandemic. 

The Anglo-Dutch company said it would boost its dividend on an annual basis in a sign of renewed confidence after it cut its dividend in April for the first time since the 1940.

The cut came in response to the slump in oil prices as Covid-19 shrank energy demand. 

Shell is planning a major restructuring as part of a plan to reduce greenhouse gas emissions to net zero by 2050 and "a complete overhaul" over the next 30 years. 

Shell said its adjusted earnings in the third quarter fell 80% to $955m but that easily beat company-provided average analysts forecasts of a $146m profit.

Today's results were driven by a record profit from Shell's marketing division, which includes the world's biggest retail network. Earnings in the segment were up 10% on the year at $1.6 billion for the quarter. 

Shell, the world's biggest Liquefied Natural Gas trader, wrote down the value of its LNG portfolio by just under $1 billion in the quarter, focusing on its flagship Prelude project in Australia. 

"As a result of Covid-19, there continues to be significant uncertainty in the macroeconomic conditions with an expected negative impact on demand for oil, gas and related products," it said. 

Shell's shares have dropped by more than 60% so far this year, more than any other major oil company, as investors fret over the impact of the pandemic on energy demand and the company's ability to cover costs despite the April dividend cut. 

Concerns about the world's shift to low-carbon energy have also weighed on the sector. 

Shell said today it would reduce the number of its oil refineries from 14 sites to six "energy and chemical parks".
