Tyson Sues to Block Rival: Tyson Foods...

Tyson Sues to Block Rival: Tyson Foods extended its $63.50-a-share tender offer to acquire Holly Farms Inc. and then filed suit to block the Holly Farms’ latest deal with rival suitor ConAgra Inc. Under a new agreement, Omaha-based ConAgra would acquire Memphis, Tenn.-based Holly Farms in a $74.81-a-share stock swap that values the company at about $1.38 billion. The bid tops the $1.1-billion ConAgra agreement that Holly Farms shareholders rejected April 14 and the current all-cash offer from Springdale, Ark.-based Tyson, which values Holly Farms at about $1.15 billion. Tyson extended its offer until 5 p.m. today.
