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.

2021 Omnibus Incentive Plan financial

"...granted to the reporting person on May 14, 2026, under Cooper-Standard Holdings Inc. 2021 Omnibus Incentive Plan, as amended and restated."

fair market value financial

"...deliver an amount of cash equal to the fair market value, determined as of the vesting date..."

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.

vesting date financial

"...equal to the fair market value, determined as of the vesting date, of a number of shares equal to the number of RSU's that have vested."

deferral election financial

"...after the grant date, subject to the director's deferral election, if applicable."
