The bidding war that erupted earlier this month over simulation software provider MSC.Software continued fast and furious this week, with the latest offer from an unnamed private equity interest upping the ante in the buyout discussions. MSC today announced that it had received a new offer of $8.30 per share from the unidentified bidders. The tug of war for control of the software company began earlier this summer with a proposal of $7.63 from private equity firm Symphony Technology Group. Earlier this month, the anonymous bidders stepped into the breach, promising $8 per share, an offer that Symphony countered last week with an $8.15 proposal. Today the stakes got higher, with the other bidder offering $8.30. As it did after the first counteroffer surfaced, MSC said today that it plans to terminate its original agreement with Symphony in favor of the higher offer. “MSC provided notice on September 21, 2009, to Symphony of the MSC board’s determination that the New Offer constitutes a superior proposal and of its intention to terminate the Symphony agreement and enter into a binding written definitive agreement concerning the New Offer after the expiration of the five-business-day notice period ending Monday, September 28, 2009,” the company said in a statement today. MSC also left the door open for further offers, saying, “Under the Symphony agreement, Symphony has the right to make a responsive offer prior to the expiration of such five-business-day period.”
