Euclidian Group will launch an estimated £125m initial public offering (IPO) in mid-July, according to chief executive James Stuart.
He said the prospectus will outline an offering of 125 million shares at £1 per share. Warren Buffett's Berkshire Hathaway has already bought 25% of the stake.
He said the insurer had yet to decide whether the float would be on the Alternative Investment Market (AIM) or a full flotation on the London Stock Exchange.
Michael Wade, chief executive of the investment vehicle the Rostrum group, joined Euclidian in April 2004 as non-executive chairman. He has spearheaded the flotation and will remain with the group after the IPO.
Accountants Mazars and venture capitalist Lexicon Partners are advising on the deal.
Stuart said: “We are looking forward to a successful IPO which will consolidate our future and realise capital for future growth.”
