The 994mln shares have been given a reference price, which is an estimated value from the LSE rather than a fixed IPO price, so the exchange can hold an auction.

If the winners hold their shares for 12 months they will receive bonus shares representing 5% of the value of their existing stake, for a maximum value of £100.
The group is also tempting potential retail investors with perks, including a chance to win a trip to its ‘Mission Days’ company conference and a “limited edition Wise swag”.
“Wise is a disruptor in the international remittances space which has previously been dominated by international banks and a handful of incumbent wire transfer businesses like Western Union and MoneyGram,” said Dan Thomas, senior analyst at Third Bridge.
