restricted stock units financial

"This security represents restricted stock units granted under the Issuer's 2015 Equity Incentive Plan"

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.

2015 Equity Incentive Plan financial

"restricted stock units granted under the Issuer's 2015 Equity Incentive Plan, as amended"

vesting financial

"This restricted stock unit grant vests in three substantially equal annual installments"

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.

Board of Directors financial

"initial one-time grant to the Reporting Person in connection with his appointment to the Issuer's 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.
