In its Q4 report, HP said it was taking an $8.8B charge primarily related to its acquisition of UK-based software company Autonomy. The company said a majority of this charge was related to "serious accounting improprieties, disclosure failures and outright misrepresentations...that occurred prior to HP's acquisition of Autonomy." On December 27, HP said the Department of Justice had opened an investigation related to Autonomy, and on February 11 the Financial Reporting Council, the UK's accounting regulator, confirmed it was investigating Autonomy. Following Dell's (DELL) February 5 announcement that it was being taken private, HP released a statement saying it plans to take "full advantage" of any opportunities presented to the company as a result of Dell's deal.

Wells Fargo issued a note in response to a story from Quartz that said HP's board was studying a breakup of the company, that said the firm thinks HP may spin off smaller units of the company, but that the PC or printer businesses are unlikely candidates to be spun off; Wells Fargo maintains a Market Perform rating on the stock. In a note earlier today, Sterne Agee maintained its Neutral rating on HP shares, saying that though shares remain inexpensive, continued pressure on HP's core businesses may reveal further downside in the stock...
