Rhea-AI Filing Summary

Organon & Co. SVP and Corporate Controller Lynette Holzbaur exercised 5,319 restricted stock units into common stock. Each RSU converted into one share, reflecting a scheduled vesting installment. Of the shares received, 1,516 were withheld at $5.84 per share to cover tax obligations.

Restricted Stock Units financial

"This price is the closing market price ... 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.

dividend equivalents financial

"Includes the addition of 82 shares of Organon common stock acquired from dividend equivalents net of withholding tax"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

tax-withholding disposition financial

"transaction_action": "tax-withholding disposition","transaction_code_description": "Payment of exercise price or tax liability"

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.
