Madame Tussauds owner Merlin Entertainments expects to be valued at as much as £3.3 billion sterling when it makes its London stock market debut next month, the group said today.
Stronger equity markets over the last 12 months have helped support a revival of European new listings after years of drought due to the financial crisis.
British insurer Just Retirement and French cable operator Numericable are among those currently taking orders for share sales.
Private-equity backed Merlin, which operates 99 attractions in 22 countries, said 20-30% of the company would be sold in the listing, in which it is offering its shares at between 280 pence and 330 pence each.
That would value the world's second-largest visitor attraction operator behind Walt Disney at between £2.86 billion and £3.34 billion.
Merlin's brands also include the Legoland theme parks and the London Eye Ferris wheel. It plans to raise £200m from the sale of new shares to reduce debt.
Its owners, the Danish investment firm Kirkbi which controls Lego Group and the private equity firms Blackstone Group and CVC, as well as company directors and employees, will also sell some of their holdings, although Kirkbi intends to remain a significant long-term shareholder.
The company plans to grow in both the US and China next year, including opening branches of Madame Tussauds in San Francisco and Beijing. It is also developing a Legoland park in Dubai and potential sites in Japan and South Korea.
"The listing will provide us with the platform for our next stage of development," chief executive Nick Varney said.
Merlin put off plans for a listing in 2010 due to jittery markets, with shareholders instead selling a 28% stake to CVC. That sale valued the company, whose sites attracted more than 54 million visitors in 2012, at £2.25 billion.
The offering, 10 to 15% of which is expected to go to private or retail investors, is due to be completed on November 12.
Members of the public, who have to invest at least £1,000 and in return will get a 30% discount on certain annual passes to Merlin sites, have until November 8 to put in orders. Institutional investors, such as pension funds, will have until November 11.
