Electrolux’s $3.3 billion deal to buy General Electric’s (GE) appliance business fell through on Monday, torpedoing the Swedish firm’s plan to bolster its U.S. business and sending its shares down as much as 15 percent. Electrolux said it would focus instead on developing existing brands such as Frigidaire, Kenmore and Tappan and could look at other acquisitions. “I’m not sure how much he will enjoy staying on now that what might have been his last deal won’t go through,” Handelsbanken Capital Markets’ Karri Rinta said.
