NEW YORK ( TheStreet) -- Popular searches on the Internet include ConAgra ( CAG) after news the company will buy food producer Ralcorp ( RAH) for $4.95 billion. The newly combined company will be the biggest private-label packaged food business in North America. The deal is valued at $6.8 billion including debt, according to ConAgra. Ralcorp shareholders will receive $90 a share in cash, a 28.2% premium to Monday's close. Ralcorp rejected several of ConAgra's offers last year, choosing instead to spin off its Post cereal business. Ralcorp's product line also includes pasta, snacks, sauces and frozen baked goods. ConAgra, which has brands including Chef Boyardee and Egg Beaters, said the deal will add to earnings in the first year. The combined company will have sales of about $18 billion annually.
