Employee Stock Purchase Plan financial

"Includes 1,000 shares acquired pursuant to the 2021 Employee Stock Purchase Plan"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

closing price financial

"purchased at a price equal to 85% of the closing price of the Issuer's common stock"
