Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers. Mattel, Inc. (the "Company" or "Mattel") held its 2026 Annual Meeting of Stockholders on May 28, 2026 (the "Annual Meeting"). As reported below, at the Annual Meeting, the Company's stockholders approved the amendment and restatement of the Mattel, Inc. Amended and Restated 2010 Equity and Long-Term Compensation Plan (the "2026 Restatement"). The 2026 Restatement, effective May 28, 2026, amends the Mattel, Inc. Amended and Restated 2010 Equity and Long-Term Compensation Plan (the "Plan," and as amended, the "Restated Plan"). The 2026 Restatement increases the number of shares of Mattel's common stock that may be issued under the Plan by 2,155,000 shares. In addition to the increase in the share reserve, the 2026 Restatement includes only one other change to the Plan, which is to extend the termination date of the Plan to March 19, 2036. The Restated Plan is described in more detail in Mattel's Definitive Proxy Statement on Schedule 14A, as filed with the Securities and Exchange Commission on April 14, 2026 (the "Proxy Statement"). The description of the Restated Plan is qualified in its entirety by reference to the full text of the Restated Plan, a copy of which is attached hereto as Exhibit 10.1.
