Comparison to Industry Standards

• Similar transactions are common among executives in publicly traded companies, especially in the biotech industry where stock options are a significant part of compensation.
• The use of a 10b5-1 trading plan is a standard practice to ensure compliance with insider trading regulations, similar to plans used by executives at companies like Amgen, Gilead, and Biogen.

Stakeholder Impact

• The transactions could have a minor impact on shareholders due to the increased supply of shares in the market, but this is likely mitigated by the pre-planned nature of the sales.
