If successful, the move would create a combined cannabis company with a footprint in 17 countries across Europe, North America and other international markets, it said. Curaleaf said it sent a follow-up letter on July 7, but Aurora has been "unwilling to engage in constructive discussions" to date. "Curaleaf remains ready to engage constructively with Aurora's board to advance this value-maximizing transaction, and we are prepared to move quickly toward a definitive agreement." A representative for Aurora Cannabis did not immediately respond to a request for comment. Curaleaf said its offer would provide Aurora shareholders with US$4.00 per share, plus US$0.75 cash for each Aurora share.
