Bark (BARK) has yet to engage with a $1.10-a-share takeover proposal made last month by GNK Holdings and Marcus Lemonis, the investor group said Wednesday in a letter to a Bark special committee.

The group said that Bark's board "initially ignored our offer, and it is now attempting to silence and handcuff the group by demanding that we sign a coercive non-disclosure agreement."

Bark is also seeking a broad "standstill" agreement that would prevent GNK and Marcus Lemonis from making any public takeover offers without explicit company approval.

The investor group said it would not agree to Bark's demands, adding that "we reiterate our proposal and look forward to your response."

Bark did not immediately respond to an MT Newswires request for comment.
