Isaias Zanatta Roberto Jacobo 4

What Happened
Isaias Zanatta, EVP & Chief Supply Chain Officer of Mattel (MAT), had 17,749 restricted stock units (RSUs) vest on May 7, 2026. Those RSUs converted into 17,749 shares of Mattel common stock. To satisfy required tax withholding at vesting, 9,031 of those shares were automatically withheld (disposed) at an effective withholding value of $15.00 per share, totaling $135,465. The RSUs had no exercise price (conversion of a derivative award).

Context

• This was an RSU vesting event with automatic share withholding to cover taxes — a routine administrative transfer, not an open-market sale or purchase.
• The withheld shares are used solely to satisfy tax obligations; no market sale by the insider is reported in this filing.
• Such vesting-and-withholding entries are common for equity compensation and do not necessarily signal a change in the insider’s view of the company.
