Actionable Insight • Neutral

Millennium's entry as a 3.7% holder adds a large, sophisticated multi-strategy fund to the shareholder base. Monitor for any subsequent 13D conversion or additional buying that could signal a more active posture. The stake is just below the 5% threshold, so any further accumulation would trigger a 13D filing with more disclosure.
