Centrica announced a huge leap in full-year operating profit, to a record £3.3bn for 2022, thanks largely to the performance of its North Sea gas production, nuclear power and energy trading divisions. The jump in operating profit is even more stark when excluding the company's now disposed-of Spirit Energy assets, coming in at £2.8bn versus £392m in 2021, and well above consensus expectations. The stellar numbers saw Centrica extend its £250m share buyback programme, launched in November, by a further £300m.
