LONDON, Oct 27 (Reuters) - Seeking to restore vigour to a business that's been languishing, Credit Suisse (CSGN.S) says it will reshape its investment bank by resurrecting the First Boston brand. Still, Credit Suisse says it expects CS First Boston to generate 14% of total group revenue by 2025, starting with annual sales of about $2.5 billion. Credit Suisse has been plagued by an exodus of senior bankers over the past 18 months. Yet most trading activities will remain within Credit Suisse, raising questions on CSFB's ability to compete with the likes of Goldman Sachs and JPMorgan (JPM.N). Credit Suisse is hoping to eventually pursue an initial public offering of CSFB, Körner told analysts.
