Last December MDN told you that investment firm Blackstone Infrastructure Partners, a major investor in pipeline company Tallgrass Energy, pursued and caught the company, tentatively convincing Tallgrass to sell its public shares of stock to Blackstone, which will take the company “private” –meaning no publicly traded shares of stock (see With Tallgrass Founder/CEO Gone, Blackstone Forces Sale/Merger). We incorrectly implied Blackstone had forced out founder and CEO David Dehaemers. It seems it was Dehaemers’ desire to cash in his chips and retire. The sale of the company was amicable and not forced. At any rate, last Thursday company shareholders voted to approve the deal and as of Friday, Tallgrass stock no longer trades on the New York Stock Exchange.
