Management Comments

• The sale is mandated by the Issuer's election under its equity incentive plans to require the satisfaction of minimum statutory tax withholding obligations to be funded by a 'sell-to-cover' transaction and does not represent a discretionary sale by the Reporting Person.

Industry Context

This transaction is a routine event for executives receiving equity compensation, common across publicly traded companies where Restricted Stock Units (RSUs) vest and require tax withholding. It does not reflect broader industry trends or competitive positioning.

Stakeholder Impact

• Shareholders: Minimal direct impact as the sale is non-discretionary and for tax purposes, not a signal of management's view on stock value. The number of shares sold is a small fraction of the company's total outstanding shares.
• Employees: No direct impact.
