Deliveroo would enter the public market by selling around 1 billion pounds of new shares in the US IPO.

On Monday, Deliveroo announced its decision to enter the public market with its IPO. The company, backed by Amazon [AMZN] has planned to sell around 1 billion pounds ($1.39 billion) of new shares in its upcoming initial public offering (IPO). This IPO is expected to be the biggest London listing in more than seven years. The food delivery company said in its regulatory fling that its listing would also include the sale of shares by some existing shareholders, potentially pushing the deal size even higher.

The company is expecting a market valuation of $7 billion through the deal, which would be the largest London IPO. In the filing, the company said it would have two classes of shares, with founder and chief executive Will Shu to be the sole holder of “class B” stock which will give each of his shares 20 votes, whilst all other shares will carry one vote. The deal is designed to protect Deliveroo from a hostile takeover. The company said the deal would last for three years. The deal is led by Goldman Sachs and JP Morgan. Bank of America, Citi, Jefferies and Numis are also part of the syndicate of banks managing the transaction.

Right now, London-listed companies cannot have a dual-class structure and gain access to the lucrative FTSE indices at the same time. But this would change if recommendations from a recent listings review are put in place.
