The Schedule 13G indicates the position is held in an investment manager capacity by Meteora Capital, LLC with Vik Mittal identified as the managing member. The filing characterizes ownership as beneficial via funds and managed accounts rather than direct individual holdings.

Because the filing reports shared voting and shared dispositive power, subsequent changes in fund strategy or additional filings could alter governance signals; future amendments would reveal any active intent.
