Keurig shareholders filed a lawsuit just a week after the news broke of JAB Holding’s plan to buy Keurig Green Mountain at $92 a share claiming the $13.9 billion merger is inadequate, reports Courthouse News Service. Due in part to the recent release of the Keurig Kold line and its expected success, shareholders believe the intrinsic value of the company exceeds the amount offered. The lawsuit also brings into question the timing of the merger as well as breaches in duty by the members of the board, according to the source.
