Rosenstein acquired a sizable stake in ConAgra last month and claimed that he would attempt to improve the company's performance and make it a more attractive stock, and it seems that he has quickly been successful in pursuing that goal. The team of professionals at JANA Partners believes that the packaged food company has disappointingly failed to create shareholder value since the acquisition of private-label food maker Ralcorp Inc. in January of 2013. On March 26, ConAgra wrote down the acquisition's value by $1.3 billion, which was a clear indicator that the strategic decision to acquire this company back in 2013 had been a failure. Yet again, JANA claims that this acquisition made by ConAgra resulted in disappointing performance for the company's shareholders, constant guidance misses, negative revisions to its long-term earnings targets, lack of dividend per share growth, and other operating performance challenges.
