The company said it won't receive any proceeds from sale of shares by the selling stockholders, according to an Associated Press report. Affiliates of Merrill Lynch & Co., one of the underwriters in this offering, are holders of the company's Series B warrants, and therefore will receive a portion of the proceeds. The other underwriters listed in the filing are Lehman Brothers, Needham & Co., Jefferies & Co. and Thomas Weisel Partners LLC. The company said it plans to list its stock on the Nasdaq Global Market under the symbol IPGP. For the six months ended June 30, IPG's net income increased to $6.12 million from $2.15 million a year earlier. The $130 million valuation for the IPO was estimated solely for calculating the registration fee, the filing said. For more information, visit: www.ipgphotonics.com
