Platform and SIPP firm AJ Bell has confirmed plans for a float on the London Stock Exchange next month with the company valued at up to £500m.

Major shareholders Invesco Perpetual and chief executive Andy Bell will have an opportunity to sell down their stakes in the business while broadening the firm’s shareholder base.

Invesco currently has a 44 per cent stake which it is expected to sell down to around 25 per cent.

Mr Bell holds 28 per cent of the business and is expected to retain around a quarter.

AJ Bell says the float would enhance its brand, extend its shareholder group, assist in recruitment and incentivisation and help with its growth strategy.
