Employee Stock Purchase Plan financial

"Includes 1,123 shares of common stock acquired under the Innoviva, Inc. Employee Stock Purchase Plan on May 15, 2026."

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.
