Tyson makes rival bid to acquire Hillshire Brands by John Kell @FortuneMagazine May 29, 2014, 10:43 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — Tyson Foods Inc. TSN unveiled a roughly $6.13 billion bid to acquire The Hillshire Brands Co. HSH , a bid that exceeds an offer by rival Pilgrim’s Pride Corp. PPC in an escalating battle to acquire the packaged-foods company. Tyson Foods, one of the world’s largest processors of chicken, beef and pork, on Thursday proposed to acquire Hillshire for $50 per share in cash, an offer that topped Pilgrim’s $45-per-share bid, an offer worth $5.5 billion. Tyson’s proposed price represents a roughly 35% premium to Hillshire’s closing stock price before it announced a deal to acquire Pinnacle Foods Inc. PF earlier in May. Both the Tyson Foods and Pilgrim’s Pride offers, if successful, would result in the termination of Hillshire’s own $6.6 billion deal including debt to acquire Pinnacle Foods. Representatives at Pilgrim’s Pride and Hillshire weren’t immediately available to comment on Tyson Foods’ takeover offer. The calculation of Tyson’s offer is based on the amount of shares outstanding Hillshire reported in late March.

For Tyson, the deal is also attractive due to the strength of Hillshire’s breakfast items, which Tyson said it has little presence today. The potential Tyson-Hillshire deal would generate synergies through the combination of sales and marketing teams, as well as supply chain resources. Those synergies were also touted by Pilgrim’s Pride earlier this week. Some analysts had suggested a merger between Hillshire and another meat company made more sense than Hillshire’s own deal to acquire Pinnacle, which has a portfolio that includes Wish-Bone condiments, Mrs. Butterworth’s syrups, and Celeste pizzas. J.P. Morgan earlier this week said the Pilgrim’s Pride bid was a “better option” for Hillshire shareholders, but at the time also suggested Tyson and several other suitors could emerge for Hillshire.

Pilgrim’s majority owner JBS SA, a Brazilian meatpacker, a few years ago sought to acquire Sara Lee but media reports in early 2011 said JBS was concerned about the cost of financing.
