Restricted Stock Units financial

"These are time-based restricted stock units (RSUs) granted to the reporting person on May 14, 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.

time-based restricted stock units financial

"These are time-based restricted stock units (RSUs) granted to the reporting person on May 15, 2025"

Time-based restricted stock units are a form of employee compensation where individuals are granted company shares that are earned over a set period, often as a reward for staying with the company. These shares typically become fully owned and transferable only after passing specific time milestones, encouraging long-term commitment. For investors, they highlight a company's focus on employee retention and can influence future stock supply and company stability.

2021 Omnibus Incentive Plan financial

"under Cooper-Standard Holdings Inc. 2021 Omnibus Incentive Plan, as amended and restated"

vest financial

"these RSU's vest and are no longer subject to forfeiture on the earlier of the first anniversary"

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.
