Restricted Common Stock financial

"The shares represent Restricted Common Stock issued under the 2023 Equity Incentive Plan"

Restricted common stock is company shares that carry limits on selling or transferring for a set period or until certain conditions are met, like time-based vesting or regulatory clearance. Think of them as shares in a locked box that gradually open; they can become freely tradable later but initially reduce the number of shares available on the market. Investors watch restricted stock because its eventual release can change a company’s share supply, affect stock price, and influence control and dilution.

2023 Equity Incentive Plan financial

"Restricted Common Stock issued under the 2023 Equity Incentive Plan that has been granted"

Board of Directors financial

"granted to the Reporting Person as compensation for serving on the Gentherm Board of Directors"

The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.
