Through the press release issued on 7 October 2021 regarding the board's decision to carry out the Rights Issue, Alligator announced that all members of the Company’s board and management with shareholdings in the Company had expressed their intention to subscribe for their respective pro rata share in the Rights Issue, in addition to the other subscription- and guarantee commitments already entered into, which secure the Rights Issue to 100 percent. Alligator hereby announces that all members of the Company's board and management with shareholdings in the Company now have, via subscription commitments, formally undertaken to subscribe for their respective pro rata share in Rights Issue.
