Director Restricted Stock Units financial
"security_title: "Director Restricted Stock Units""
Director restricted stock units are promises by a company to give board members company shares in the future, usually after a set time or when certain conditions are met. They matter to investors because they can dilute existing shareholders when converted to shares and reveal how the board’s pay is tied to the company’s performance—like a delayed paycheck in company stock that aligns a director’s interests with shareholders and can affect share supply when released.

vest financial
"The restricted stock units vest in 364 days from date of issuance."
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.
