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.

"The shares were withheld by the Issuer to satisfy income tax withholding obligations associated with the quarterly vesting of previously granted employee equity grants."
