Bidding War Brews For Dresser-Rand Group Inc.

Dresser-Rand Group Inc.'s

prospects for getting acquired by Sulzer AG became less clear Friday with reports that two additional suitors have emerged. Siemens AG

is considering an offer of more than $85 a share for the Houston-based energy drilling equipment supplier, according to a Bloomberg report Friday. Separately, the Financial Times said General Electric Co.

is weighing an offer. Both reports cited unnamed sources. Dresser-Rand closed Friday up more than 9 percent. Zurich-based Sulzer confirmed earlier this week its in "non-exclusive" talks with Dresser-Rand about a "potential transaction'" GE has grown its oil and gas unit recently through acquisitions, and analysts floated the possibility earlier this month it could nurture an interest in Dresser-Rand. The deal could raise anti-trust issues, however. Siemens got burned in a bidding war with GE as recently at June when its $6.39 billion offer for Paris-based Alstom got beaten by the U.S. conglomerate's $11.37 billion proposition.
