Mattel Reports Officer or Director Changes in an SEC Filing

The El Segundo company disclosed it in a Form 8-K filed with the SEC on Oct. 22.

Mattel, the El Segundo company, whose shares trade on Nasdaq under the symbol MAT, reported a change involving its directors or officers in a Form 8-K filed with the Securities and Exchange Commission on Oct. 22.

The filing says Mattel’s board appointed Lee Matheson, a partner at EdgePoint Investment Group, as a director on Oct. 21 under a cooperation agreement with EdgePoint, and grew the board from nine to ten members. His term runs to the 2027 annual meeting, and Mattel agreed to nominate him for re-election then.

In a press release filed with the report, Mattel called EdgePoint “an approximately 18% stockholder” of the company.

It follows an earlier filing of the same kind, on Oct. 19, in which the company wrote: “On October 19, 2026, Mattel, Inc. (the ‘Company’ or ‘Mattel’) announced that Peter Griffith has been appointed Chief Financial Officer of the Company (‘CFO’) and as a non-independent director of the Board of Directors of the Company (the ‘Board’), in each case effective October 20, 2026 (the ‘Start Date’).”

The Globe follows L.A. County companies’ records in its L.A. Layoff Tracker and its L.A. Startup Money Tracker, which explains what each kind of 8-K report means.
