restricted stock units financial
"These 904 restricted stock units vested on July 2, 2026 and were settled in shares of Common Stock"
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.
tax withholding liability financial
"326 shares were withheld by International Seaways, Inc. in payment of the Reporting Person's tax withholding liability"
Management Incentive Plan financial
"pursuant to the International Seaways, Inc. 2025 Management Incentive Plan (the "Plan")"
A management incentive plan is a structured pay program that rewards company executives and senior managers when they meet specific goals, using cash bonuses, stock awards, or options. It matters to investors because it helps align leaders’ actions with shareholder interests—like tying a coach’s bonus to a team’s wins—while influencing retention, risk-taking and potential share dilution, all of which can affect company performance and stock value.
