After weeks of negotiations, IBM reportedly is eyeing a $9.55-per-share buyout for Sun Microsystems, according to a report in The Wall Street Journal. Such a price would value the deal at roughly $7 billion and offer Sun investors nearly double the price of the stock before reports surfaced earlier this month that the parties are in buyout talks. A report in The New York Times, meanwhile, notes the parties are discussing a purchase price of $9.50 a share. In either case, Sun’s investors haven’t seen the hardware maker’s stock trade at those levels since August. Last spring, Sun was trading at a 52-week high of $16.37 a share.
