Lansons advised Metro Bank on its successful listing on the London Stock Exchange last week.
Metro Bank raised £400m through a private placement to existing and new shareholders before listing its shares on the Main Market last Thursday.
Lansons has advised Metro Bank on all external communications since before its 2010 launch when it became the first new high street bank in the UK for more than 100 years.
Tom Baldock, director, Lansons, said: “Metro Bank has delivered on its promise to build a revolutionary new bank. Raising £400m in volatile markets to further support its growth plans is an incredible achievement and shows the faith investors have in Metro Bank’s leadership and business model.”
