Explanation of Responses:

1. As disclosed on a Form 8-K filed on September 13, 2024 ("Form 8-K"), Performance-Based Restricted Stock Units were granted to the Reporting Person on September 30, 2024, pursuant to the Mattel, Inc. Amended and Restated 2010 Equity and Long-Term Compensation Plan, as amended (the "Plan"), including Performance-Based Restricted Units with vesting tied to stock price performance hurdles ("Performance Units"). Each Performance Unit represents a contingent right to receive one share of Mattel, Inc. Common Stock (or, at the election of Mattel, Inc., a cash amount equal to the fair market value of such share).

2. The Performance Units are subject to performance-based vesting requirements tied to stock price performance hurdles. The Performance Units set forth in the table above will become eligible to vest upon achievement of the following stock price hurdles at any time during the period beginning on September 30, 2026 and ending on September 30, 2029 (the "Performance Measurement Period"): (i) 0% of the Performance Units for a stock price hurdle of $27.00, (ii) 50% of the Performance Units for a stock price hurdle of $33.50, and (iii) 100% of the Performance Units for a stock price hurdle of $40.00. A stock price hurdle will be achieved only if the average closing price of the Issuer's common stock is equal to or greater than the hurdle for 30 consecutive trading days during the Performance Measurement Period. Linear interpolation will be used for achievement levels between the stock price hurdles.

3. If Performance Units become eligible to vest, the eligible Performance Units will vest and settle within fifteen (15) business days following September 30, 2029 and approval by the Compensation Committee of the Board of Directors of Mattel, Inc. of the achievement of the stock price hurdles, but in no event later than March 15, 2030, subject to the Reporting Person's continued employment with the Issuer through the settlement date. In addition to the Performance Units described above, separate Performance-Based Restricted Units will become eligible to vest based on the Issuer's relative total stockholder return over a period beginning on September 30, 2024, and ending on September 30, 2029 (as more fully described in the Form 8-K).
