British footwear group Dr Martens entered the London Stock Exchange Friday, valuing the iconic brand at £3.7 billion (5.1 billion, 4.2 billion euros).
The maker of boots and shoes, whose internet sales have boomed worldwide during the coronavirus pandemic, immediately jumped above its initial public offering (IPO) of 370 pence a share to open at 425 pence.
Full trading, when institutional investors will be joined by individual buyers, starts on Wednesday.
"We have been delighted by the strong levels of interest, engagement and support from such a high quality selection of institutional investors," Dr Martens chief executive Kenny Wilson said in a statement Friday.
"We are proud to take our place as a London-listed company..., continuing to grow our brand around the world."
Private-equity group Permira, which seven years ago bought Dr Martens for £300 million, led the flotation of 35 percent of the group.
Dr Martens' revenue jumped by around one-fifth to £318 million in the six months to September 2020 from a year earlier.
