Constellation Energy Group shareholders have filed six lawsuits in Baltimore City Circuit Court since the power company announced in late April that it had agreed to sell itself to Chicago-based Exelon Corp. for $7.9 billion in an all-stock deal.
In a filing Monday with the Securities and Exchange Commission, Constellation said the class-action lawsuits allege the company's directors breached their fiduciary duties because the deal does not maximize shareholder value.
