NCIBKnight repurchase for cancellation on December 21: 2,999,497 shares at @5,10$.
Just speculation but it could be the final portion of the shares owned by Medison? The extract below was in a press release of GUD on November 19, 2019 and the four year period for Medison to divest is almost over since the separation agreement closed in March 2020:
In addition, the parties agreed to release each other from all claims and withdraw all legal proceedings initiated by both parties. Finally, Medison, which together with its affiliates own approximately 10,400,000 shares or 7.5% of Knight, agreed to a four-year standstill commitment and will divest its position in Knight during this period. This separation agreement is expected to close in the first half of 2020.
