Restricted Stock Units financial

"This price is the closing market price of Organon & Co. common stock ... under which the Restricted Stock Units ("RSU") were awarded."

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.

Each RSU financial

"Each RSU represents a contingent right to receive one share of Organon common stock."

Exercise or conversion of derivative security financial

"transaction_code_description": "Exercise or conversion of derivative security""

tax-withholding disposition financial

"transaction_action": "tax-withholding disposition""

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
