Stakeholder Impact

• Shareholders may view the significant sale of shares by a major beneficial owner negatively, potentially leading to downward pressure on the stock price.
• The transactions are conducted under a pre-established plan, which is designed to mitigate concerns about insider trading, but the volume may still affect market perception.
