FILE - In this Monday, Nov. 23, 2015, file photo, a man enters Pfizer's world headquarters, in New York. Pfizer will not split into two publicly traded companies, a decision that, at least for now, ends Wall Street speculation over the drugmaker's future. The company believes it is best positioned to maximize shareholder value in its current form, but said Monday, Sept. 26, 2016, that it's reserving the right to split in the future if the situation changes.
