Siemens reportedly has complained of a lack of cooperation from Alstom. The GE offer is supported by Alstom's largest investor, the French conglomerate Bouygues, which is controlled by billionaire Martin Bouygues. GE investors don't seem opposed: since reports of the deal first surfaced last Wednesday, its stock has perked up slightly, rising 1.6% to $26.86 in early afternoon trading today. Analysts by and large have applauded the deal. Deane Dray of Citi Research thinks the valuation is reasonable and that there could be upside to the $1.2 billion in cost savings GE is targeting to achieve by the fifth year. Brian Langenberg, principal of Chicago-based Langenberg & Co., called it a "huge opportunity to whack Siemens upside the head on their home turf."
