Restricted Stock Units financial

"These restricted stock units convert into common stock on a one-for-one basis ("RSUs")."

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.

RSUs financial

"These RSUs will vest with respect to 1,319 RSUs on 3/24/2027, 1,319 RSUs on 3/24/2028 and 835 RSUs on 3/24/2029, except as otherwise provided in the award notice."

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

2020 Graham Corporation Equity Incentive Plan financial

"These RSUs were granted under the 2020 Graham Corporation Equity Incentive Plan in a transaction exempt under Rule 16b-3"

Rule 16b-3 regulatory

"These RSUs were granted under the 2020 Graham Corporation Equity Incentive Plan in a transaction exempt under Rule 16b-3"

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.
