Restricted Stock Units financial

"Represents Restricted Stock Units ("RSUs") granted on October 1, 2026"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

2025 Equity Incentive Plan financial

"under the Issuer's 2025 Equity Incentive Plan"

vesting financial

"The RSUs shall vest in three equal installments"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

Restricted Stock Unit Award Agreement financial

"pursuant to a Restricted Stock Unit Award Agreement and the 2025 Plan"

A restricted stock unit (RSU) award agreement is a formal promise from a company that an employee or contractor will receive company shares (or cash equal to their value) after meeting certain conditions, such as staying with the company for a set time or hitting performance targets. Investors care because RSUs can dilute existing shares when converted, reveal how management is paid and incentivized, and signal future share issuance that can affect earnings and stock value.
