NEW YORK ( TheStreet) -- Starboard Value, a burgeoning activist hedge fund with a 5.7% stake in Smithfield Foods ( SFD), says it opposes the company's $34 a share sale to Chinese foods giant Shuanghui International Holdings and believes the integrated pork processor is worth more broken up in three parts. Smithfield Foods is worth between $43.85 a share and $55.21 a share, according to Starboard, if the company's hog production, international and pork processing operations were split into three separate parts, the hedge fund argued in a Monday letter to Smithfield's board of directors. Although Starboard has been successful in some activist efforts such as patent sales at AOL ( AOL) in 2012, investors didn't bid up Smithfield shares in Monday trading. Smithfield shares rose about 1% to $33.15, underperforming gains posted by the broader S&P 500 Index. Starboard is likely to have a significant annualized profit on its investment in Smithfield Foods even if Shuanghui relents with its $34 a share offer. The fund bought Smithfield Foods shares in March, when shares were about 25% below current levels. A separation of Smithfield's three integrated foods units is feasible without "tax leakage" that is usually part of asset sales or spinoffs and the company's pork processing unit contains significant room for operational efficiency and margin growth, Starboard argued in its letter. While the hedge fund appears to see reason for Smithfield to divest its hog and international businesses and retain its pork operations, Starboard also says several strategic acquirers are likely for each of Smithfield's divisions. The fund also concedes a competing bid for all of Smithfield may be hard to broker, given the company's signed merger agreement with Shuanghui, in a $7.4 billion takeover that would be the largest for a Chinese firm in the U.S. Instead, Starboard is seeking to explore asset sales and spinoffs that may garner what it believes is a more full valuation of the company. "Starboard is seeking to identify and connect any strategic or financial buyers for the Company's individual business units to determine if it would be possible to structure a sum-of-the-parts transaction that could deliver greater value for shareholders than the Proposed Merger," the fund writes of its activist efforts. Earlier in June, Continental Grain, once a top shareholder in Smithfield Foods, said it would support the company's planned sale . "Continental Grain congratulates Smithfield on the proposed merger with Shuanghui International. We have been advocating for value creation and are pleased that the Smithfield board of directors and management are being proactive in realizing value for the benefit of all of its shareholders," Paul J. Fribourg, Chairman and Chief Executive Officer of Continental Grain, said in a June 3 statement. Fribourg added that the 200-year old food and agribusiness company has exited its stake in Smithfield. "
We have elected to exit our long-term ownership position in Smithfield because we are satisfied with our investment return," Fribourg said. Prior to Smithfield's May 29 announcement of a takeover proposal, Continental Grain had sought to split up the vertically integrated pork manufacturer. Continental Grain argued the sum of Smithfield's hog production unit and its meat processing and distribution operations internationally could be worth $40 a share.
