restricted stock units financial

"These securities are restricted stock units that were granted on May 27, 2026"

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.

stock incentive plan financial

"pursuant to the Silgan Holdings Inc. Second Amended and Restated 2004 Stock Incentive Plan"

A stock incentive plan is a company program that gives employees or directors pieces of ownership or the right to buy shares over time, similar to receiving a bonus paid in company stock instead of cash. Investors pay attention because these plans align staff incentives with long‑term company performance but can also dilute existing shareholders and affect reported profits when grants are expensed, so they influence both ownership percentages and financial results.

vested financial

"and become fully vested on the date of the next annual meeting of stockholders"

settled in shares financial

"These restricted stock units will be settled in shares of Common Stock on a 1-for-1 basis"
