Restricted Stock Units financial
"These restricted stock units, which convert into common stock on a one-for-one basis, were granted under the 2020 Graham Corporation 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.
2020 Graham Corporation Equity Incentive Plan financial
"were granted under the 2020 Graham Corporation Equity Incentive Plan in a transaction exempt under Rule 16b-3"
Rule 16b-3 regulatory
"in a transaction exempt under Rule 16b-3 and, except as otherwise provided in the award notice, vest on 6/1/2027"
Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.
vest financial
"vest on 9/2/2026, except as otherwise provided in the award notice"
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.
