(Reuters) - A blank-check company backed by Michael Dell’s family office and Gregg Lemkau, the former co-head of investment banking at Goldman Sachs Group Inc, on Friday filed paperwork to raise up to $500 million in its initial public offering. MSD Acquisition Corp said it is aiming to sell 50 million units at $10 each. (bit.ly/3dv8JHO) Lemkau, one of the most high-profile dealmakers on Wall Street, will lead the blank-check vehicle and John Phelan, co-founder of MSD Partners, will serve as the chairman. Lemkau, who was widely seen as a potential candidate for the role of Goldman Sachs’ chief executive officer, retired from the bank last year to join MSD Partners, which is the family investment office of Dell Technologies Inc founder Michael Dell. Before being tasked to serve as co-head of investment banking in 2017, Lemkau had jointly led Goldman’s mergers and acquisition department for a number of years. Goldman and Morgan Stanley are the underwriters for MSD Acquisition’s IPO.
