Berenberg, Germany's oldest bank, has won a role on the Sfr1.3 billion ($1.3 billion) IPO of Swiss telecoms provider Sunrise Communications, months after advising on its biggest listing to date.

Managing partner Hendrik Riehmer and head of equity capital markets Oliver Diehl both advised on the $1.7 billion Rocket Internet IPO last October, alongside bankers at JP Morgan and Morgan Stanley. It was Berenberg's largest bookrunner role to date and the two bankers are now advising on the Sunrise float as joint bookrunners with Morgan Stanley.
