restricted stock unit financial

"shares will vest on September 1, 2027 and be issued upon settlement of a restricted stock unit award"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

2024 Stock Incentive Plan financial

"award granted under the Northern Technologies International Corporation 2024 Stock Incentive Plan"

vesting financial

"These shares will vest on September 1, 2027 and be issued upon settlement"

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.

settlement financial

"be issued upon settlement of a restricted stock unit award granted"

Settlement is the process of completing a financial transaction, like buying or selling a stock, by transferring money and ownership between parties. It ensures that both the buyer gets the asset and the seller gets paid, making the deal official. Without settlement, the transaction wouldn't be finalized or legally recognized.
