Apollo Global Management is among a group of financial firms in talks to take a stake in Credit Suisse’s revamped investment bank, people familiar with the matter said.

Credit Suisse said last year that it would carve out the advisory part of its investment-banking operation into a new entity under the resurrected CS First Boston brand following a string of scandals. The bank said it would raise outside capital to launch the new entity, which it hopes to list in a separate initial public offering eventually.
