Metro Bank has reportedly appointed advisers for an initial public offering which could take place as soon as the first quarter of 2016.
Sky added that so far, Metro has raised over £600m from investors, and as such a successful flotation could put it close to the mooted £1bn valuation of the business.
The move comes despite the Treasury's plans for a new corporation tax surcharge, which will take an additional eight per cent of banks’ profits each year. It applies to banking institutions making more than £25m a year, meaning many of the newer, smaller banks will be hit.
Metro cut its losses to £8.9m in the final quarter of 2014, down from £9.4m in the previous three-month period, as it edges closer towards profitability.
The bank declined to comment.
