Shares surged to levels not seen since May 2019 following the company’s update.
Centrica credited its electricity generation and gas production activities for the upgrade – as opposed to profitability at its household supply arm.
The company said it now expected full year adjusted earnings per share (EPS) above 30p.
EPS – a measure of profitability calculated through the number of shares in circulation – had previously stood at the upper end of a 15.1p to 26p guided range following several upgrades.
