Meghji was, at the time of the reported transactions, the sole shareholder of M III Acquisition Partners I Corp., which is the sole general partner of Sponsor I LP. Mr. Meghji subsequently transferred the stock of M III Acquisition Partners I Corp. to an affiliate of its sole limited partner (reported on Form 4 filed on March 29, 2018).
