By Reuters Staff 2 Min Read (Reuters) - Private label food group TreeHouse Foods on Tuesday appointed two new independent directors to its board, three weeks after activist investment firm Jana Partners urged the company to consider selling itself. TreeHouse said it shares a “common perspective” with Jana, which has said the stock remains undervalued nearly three years into a turnaround. The company said its current share price does not reflect the progress it has made. Jana, which owns 7.4% of TreeHouse’s shares and has a history of pushing for change in the food and beverage industry, in late January nominated three directors to the TreeHouse board.
