The impending float of SSP adds to the growing excitement over the return of the London IPO market, which has taken off in recent weeks with a bumper crop of potential listings.
SSP's owner, Swedish private equity group EQT, is already behind the float of Danish cleaning firm ISS, which this week dusted off plans to come to market and raise $1.5 billion.
A range of household names are also preparing to list, with this week seeing Poundland ready a £700 million float and Pets at Home chew over a £1.5 billion IPO. Meanwhile, internet sensation Just Eat has cooked up interest thanks to its rich price expectations, which could value the company as much as 90 times 2013 earnings before interest, tax, depreciation and amortisation – making it one of the most pricey tech stocks on the London Stock Exchange.
