Several weeks ago the founder and CEO of Tallgrass Energy, David G. Dehaemers Jr., abruptly quit the company retired (see Tallgrass Energy Founder/CEO/Chairman David Dehaemers Retires). Blackstone Infrastructure Partners, a major Tallgrass investor, wants to buy the company and take it private. That is, a takeover. Dehaemers was not happy but couldn’t prevent it, so he left. With Dehaemers out of the way, Blackstone sealed the deal.[Correction: MDN was contacted by Tallgrass to set the record straight. David Dehaemers telegraphed back in January he would likely not remain with the company after 2019. This was, indeed, a retirement and he was not (as MDN had implied) forced out. We regret the error and send our apologies to Tallgrass.] Yesterday Tallgrass issued a statement to say Blackstone, using its own considerable pile of cash along with money from several others, has signed a deal to buy Tallgrass.
