London Stock Exchange Group plc and Deutsche Borse AG have finalized a merger agreement after more than a decade of deal talk. The combined company will have a market value of about $30.6 billion. 'Under this industry-leading combination, the companies will merge to create a leading Europe-based global markets infrastructure group, resulting in a significantly enhanced product offering for customers and in leading positions across multiple asset classes,' the partners said in a statement. While the companies are billing the all-share combination as a merger of equals, the German exchange operator would be in the driver's seat, with Deutsche Borse CEO Carsten Kengeter serving in the same role at the enlarged entity while his counterpart at LSE would step aside. Deutsche Borse shareholders would get 54.4% of the combined entity and London Stock Exchange shareholders 45.6%. The Deal's Senior Reporter Lisa Allen has the details from New York.
