Shareholders in claims manager National Accident Helpline stand to make £32.7m when the company floats on the London Stock Exchange next week.

The marketing collective, which has around 40 law firms on its panel, has announced the pricing of its initial public offering ahead of its floatation on the AIM market.

The placing price has been set at £2 per ordinary share, with the total value of the issued shares estimated at £82.3m

The selling shareholders are Inflexion 2006 General Partner Limited and Inflexion Co-investment Limited, Lloyds Development Capital (Holdings) Limited, OBS 2009 and LDC Opportunity Club and certain individual shareholders comprising current and former members of the NAHL Group’s management.

Following the placing, the directors will hold 12% of the ordinary shares, with Inflexion, Lloyds Development Capital and Alan Kennedy (founder) holding 15.01%, 15.01% and 9.15%, respectively.

The trading of ordinary shares is expected to start at 8am on 29 May.

The National Accident Helpline brand has become well-established since it was founded in the UK in 1993, largely down to advertising spend of more than £200m. In 2013 it generated more than 70,000 enquiries to pass onto its panel members.

In the year ended 31 December 2013, the group generated revenues of £39.7m and operating profit of £9.8m

Russell Atkinson, chief executive, said this is a ‘natural time’ for the company to go public. ‘We have a long track record of consistent and profitable growth with a highly cash generative business model which we expect will deliver an attractive yield for investors.

‘The legislative changes that were introduced in April 2013 have been embedded and we believe an IPO will provide an excellent platform for the group to take advantage of the significant growth opportunities that this legislation has created.’
