Comparison to Industry Standards

• The use of a 10b5-1 trading plan is a common practice among executives at publicly traded companies, including those in the tech and cryptocurrency sectors.
• Similar to executives at companies like Block (formerly Square) or PayPal, Armstrong is utilizing a pre-arranged plan to manage his stock sales.
• The volume of shares sold is relatively small compared to the total outstanding shares of Coinbase, which is typical for these types of transactions.

Stakeholder Impact

• Shareholders may react to the stock sales, potentially influencing the stock price.
• The impact on employees, customers, suppliers, and creditors is likely minimal, as the transactions are related to executive compensation and personal financial planning.
