restricted stock units financial

"On May 14, 2025, the reporting person was granted 4,860 restricted stock units, all of which vested on the first anniversary of the grant date."

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.

change in control financial

"until the earlier of (i) a separation from service from the Company and (ii) a change in control of the Company."

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

separation from service financial

"until the earlier of (i) a separation from service from the Company and (ii) a change in control of the Company."
