The new chief executive of Britain’s BT Group (BT.L), Allison Kirkby, outlined a plan on Thursday to more than double the company’s free cash flow over the next five years as it moves past the peak of its fibre network investments. Kirkby, who previously led Sweden’s Telia, announced that BT would increase its dividend for the 2024 financial year by 3.9% to 8 pence per share following a better-than-expected free cash flow performance.
