RBC Capital believes that ConAgra's (CAG) stock could reach $51 if it sells its Lamb Weston unit at a premium while minimizing its tax liability from the deal and then quickly pursues acquisitions. The firm continues to view Pinnacle Foods (PF) as ConAgra's most likely target, In RBC's base case scenario for ConAgra, the company spins off Lamb Weston at a modest discount to its branded peers, and ConAgra garners a modest premium valuation due to its tax asset from the loss on the sale of its private brands. In that scenario, RBC says that ConAgra's shares would be worth $46. It keeps a $46 price target and Sector Perform rating on the stock.
