Context

• This reporting party is a 10% institutional owner, not an executive — institutional trades can reflect portfolio decisions rather than insider views of company operations.
• Because both a large purchase and a small sale occurred the same day, the activity may reflect rebalancing or other portfolio management; the filing provides no reason.
• Amended filing suggests a correction or update to an earlier report; investors should consult the amended Form 4 for exact details.
