Key Terms

4 terms

restricted stock units financial

"The reported securities represent restricted stock units ("RSUs") which each entitle the reporting person to receive one share"

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.

vesting financial

"The RSUs will vest in three installments of 30% on April 26, 2026, 30% on April 26, 2027 and 40% on April 26, 2028"

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.

continued employment financial

"subject to continued employment through each such date"

Continued employment means that an individual remains in their current job without interruption. For investors, it signals stability and ongoing work that can affect company performance and future prospects. Like a steady heartbeat for a business, sustained employment helps ensure consistent operations and financial health.

grant, award, or other acquisition financial
