Stock Units financial

"Each stock unit represents a right to receive one share of common stock."

Stock units are individual pieces of ownership in a company, like slices of a pie that together make up the whole business. They matter to investors because each unit represents a claim on the company’s assets, profits and sometimes voting power, and changes in the number or value of these units affect ownership percentages, potential dividends and share dilution — all of which influence an investment’s worth.

vest financial

"The stock units are scheduled to vest at Valero Energy Corporation's 2027 annual meeting of stockholders"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

Stock Unit Award Agreement financial

"subject to a one-year hold requirement per the terms of a Stock Unit Award Agreement"
