Restricted Stock Units (RSUs) financial

"Represents a grant of Restricted Stock Units (RSUs) which vest as follows"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

vest financial

"RSUs which vest as follows: one-twelfth (1/12) of the RSUs shall vest"

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.

Effective Date financial

"three (3) months following the Effective Date of April 10, 2026"

The effective date is the specific calendar day when a contract, regulatory action, corporate change, or financial disclosure officially begins to apply and take legal or operational effect. For investors, it marks the moment rules, obligations, ownership, pricing, or reporting change—similar to the exact minute a light switch is flipped—so it determines when rights, liabilities, or market impacts start and which periods or transactions are affected.
