W.E.T. Automotive Systems AG
Shares of Amerigon Incorporated (Nasdaq: ARGN) soared more than 13% Monday -- and another 10% by mid-session today -- after announcing an agreement to acquire its larger competitor W.E.T. Automotive Systems AG (XETRA: WET.DE) for euro 121.6 million ($166.6 million). If the deal is approved by shareholders and regulations, it will end litigation between the two companies over patents for energy efficient thermal seats for automobiles.
