Physics jokes are not standard fare in City research notes, but Deutsche Bank could not resist.
Its analyst Robert Grindle has likened BT Group PLC's (LSE:BT.A) new chief executive to a “quantum-confined Stark effect”, coining the “BT-confined Allison Effect”, shorthand for the fresh energy of Allison Kirkby and how it may be altering investor perception of the group.
The trouble, as Grindle sees it, is that while management enthusiasm may brighten the long-term story, Deutsche points to the possibility of £3 billion in free cash flow by 2030, once pension top-ups and restructuring costs subside, the short-term competitive picture looks less flattering.
The broker has a 'sell' rating and a 140p target, well below the current 187.17p share price, down 2.3%.
Its worry is the here and now: cut-throat broadband pricing, pressure in mobile, and a consumer market still grappling with inflationary strain. Those trends, Deutsche argues, are more certain than the distant cash flow hope.
Investors have warmed to Kirkby’s early signals on simplification and costs, and BT’s share price has rallied this year.
But Deutsche’s call is a reminder that energy at the top does not dissolve the structural challenges in UK telecoms. Long-term promise is one thing; fighting off fibre rivals in the meantime is quite another.
