Restricted Stock Units financial

"The Restricted Stock Units ("RSUs" or "Units") were granted on May 1, 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.

Amended and Restated 2010 Equity and Long-Term Compensation Plan financial

"granted on May 1, 2026 pursuant to the Mattel, Inc. Amended and Restated 2010 Equity and Long-Term Compensation Plan"

contingent right financial

"Each Unit represents a contingent right to receive one share of Mattel, Inc. Common Stock"

tax withholding financial

"one share of Common Stock on the date of vesting), subject to tax withholding"

Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.
