Simon, who founded Hain Celestial Group in 1993, an organic food company he took public and grew into a $3 billion (annual sales) business, oversaw the merger of Aphria and Tilray four years ago. The deal, which valued the combined company at nearly $4 billion, was structured as a reverse acquisition of Tilray—each Aphria shareholder received approximately 0.8 Tilray shares, worth $6.20 at the time, for each Aphria share they owned.
