Lexicon Partners, the specialist independent M&A boutique, has gained its third financial services sector mandate of the month by advising CVC on its £144m (€202m) buyout of IG Group, the UK spread-betting company.

The deal, which values IG Group at 255p per share, is a coup for Lexicon because CVC usually works with large US investment banks, such as Goldman Sachs, Lehman Brothers and Morgan Stanley.
