Industry Context

They can be driven by various factors, including personal financial planning, tax obligations, and diversification strategies. The use of Rule 10b5-1 trading plans is a standard practice to avoid accusations of insider trading.

Comparison to Industry Standards

• Executive compensation packages often include stock options and restricted stock units, leading to periodic sales to cover taxes or diversify holdings.
• Rule 10b5-1 trading plans are widely used by corporate insiders to schedule stock sales in advance, mitigating the risk of insider trading allegations.
• Comparing the volume and frequency of Hewes's sales to those of executives at comparable biotech companies (e.g., executives at companies like Vertex Pharmaceuticals, Amgen, or Regeneron) could provide further context.

Stakeholder Impact
