Danone to buy US soy brand

Danone SA has agreed to buy WhiteWave Foods Co for about $10 billion to add the best-selling US soy milk brand Silk and expand in organic food in its biggest acquisition in almost a decade.

Investors will receive $56.25 a share in cash, Danone said in a statement on Thursday. That's 19 percent higher than WhiteWave's closing price on Wednesday. WhiteWave began trading in 2012 after US dairy company Dean Foods Co spun off the unit, which was its most profitable business.

The acquisition would make Danone the global leader in fresh dairy and health-food brands including Horizon milk, Wallaby Organic yogurt and Earthbound Farm packaged salads as consumers increasingly shun processed foods perceived as unhealthy. WhiteWave's Silk is the biggest-selling soy milk brand in the US, benefiting from a shift to dairy alternatives like almond milk.
