Mattel Names Peter Griffith CFO and Board Director, Effective 20 October 2026

Mattel has named Peter Griffith Chief Financial Officer and a member of its Board of Directors, effective 20 October 2026. He succeeds Paul Ruh, who will serve as an adviser through the end of the year. Mattel announced the appointment on Monday, 19 October 2026, and Retail Dive reported it. Three outlets covered the change: Retail Dive, The Toy Book and CFO Dive. This article marks which details come from only one of them.

Each section below names the outlet behind its details, so a reader can check any claim against the original report. The three outlets agree on the core facts: the title, the effective date, the succession from Paul Ruh and the board seat. Where a detail rests on a single outlet, the section says so.

Who is Peter Griffith replacing?

Griffith succeeds Paul Ruh as CFO. Retail Dive reports that Griffith "succeeds Paul Ruh, who will serve as an adviser through the end of the year." That single sentence carries the whole handover: the CFO seat changes hands, and the outgoing officer stays on in an advisory capacity.

In practical terms, the CFO seat changes hands while Ruh moves into an advisory role. Readers who follow Mattel's leadership changes will want to note that the succession is the one finance change the reporting describes. The sources describe his next step only in those terms. They say nothing about what the advisory role covers, and this article does not guess. For readers tracking Mattel's finance leadership, the handover is one change: Griffith succeeds Ruh, and the reporting describes no other finance role.

When does Peter Griffith start?

Griffith's appointment takes effect on 20 October 2026, a Tuesday. The Toy Book reports that he "will join the company as Chief Financial Officer on Oct. 20 and take a seat on Mattel's Board of Directors." The announcement came one day earlier. Retail Dive gives the same timing: the appointment is effective Tuesday, according to a Monday press release. The sources describe no interim period between the announcement and the start date. Because both outlets give the same effective date, it is the least disputed detail in the reporting.

Put simply, the announcement and the start date are two separate events. Mattel made the appointment public on Monday, 19 October 2026, and the appointment takes effect the following day, Tuesday, 20 October 2026. Retail Dive and The Toy Book agree on the effective date of 20 October 2026, and all three reports are dated 19 October 2026.

Does Peter Griffith join Mattel's board?

Yes. Both Retail Dive and The Toy Book report that Griffith will sit on Mattel's Board of Directors. Retail Dive's wording is that Griffith "will join the company's board of directors and report to CEO Roger Lynch." That reporting line is the only detail in the sources about how Griffith fits into the leadership team.

The two outlets use different wording for the same seat. The Toy Book says Griffith will "take a seat on Mattel's Board of Directors," while Retail Dive says he "will join the company's board of directors." The phrasing differs, but both reports place Griffith on the board as of the start date, and this article treats the board seat as confirmed by both.

What is Peter Griffith's background?

Griffith most recently served as Executive Vice President and CFO of Amgen, according to The Toy Book. Retail Dive reports that he also spent more than two decades as a partner at the accounting and professional services firm EY.

The two reports together make up the background in this article. The Toy Book names the Amgen role, and Retail Dive adds the EY partnership. This article does not add to either account.

How much is Peter Griffith's sign-on bonus?

According to CFO Dive, Griffith will receive a cash sign-on bonus of $1.4 million. In its words, "Incoming Mattel Inc. CFO Peter Griffith will receive a cash sign-on bonus of $1.4 million." Until a second outlet or a filing confirms the figure, treat it as reported rather than verified.

CFO Dive is the only one of the three outlets cited for the bonus, and the other two reports do not mention it. The headline of that report names the sign-on bonus directly, which is why it is the source for this section. The figure is presented as CFO Dive reports it and is not compared against any other source.

What is the timeline of the change?

The table collects every dated event in the reporting. It runs in order, from the announcement on Monday to the advisory period that runs through the end of 2026. Two rows carry the same outlets because both Retail Dive and The Toy Book report the announcement and the effective date.

Where each detail comes from

Each bullet names the outlet and the date of the report it draws on, so a reader can go back to the original page.

• Retail Dive (19 October 2026): the 20 October effective date, the succession from Paul Ruh, Ruh's advisory role through the end of the year, the board seat, the reporting line to CEO Roger Lynch, and more than two decades at EY.
• The Toy Book (19 October 2026): the 20 October start date, the board seat, and the Amgen background.
• CFO Dive (19 October 2026): the $1.4 million cash sign-on bonus.

All three reports are dated 19 October 2026, the day the announcement became public, so none of them is a later update to the story. A reader who wants the original wording can open the outlet linked in each section and compare the quote against this article.

Retail Dive's bullet is the longest because that outlet covers the most details: the effective date, the succession from Ruh, Ruh's advisory role, the board seat, the reporting line to Roger Lynch and the EY background. The Toy Book supplies the start date, the board seat and the Amgen background. CFO Dive supplies only the bonus.

What's still unclear?

The sources do not say why Mattel is changing its CFO. The $1.4 million sign-on bonus rests on one outlet, so treat it as reported rather than confirmed. The sources describe Ruh's advisory role only as lasting through the end of the year, with no detail on his responsibilities. The reporting also does not say whether the advisory role carries any formal title or duties beyond the end of the year.

Readers who want to check any detail can open the outlet linked in the matching section. The three outlets agree on the announcement date, the effective date, the succession and the board seat. The only figure that rests on a single source is the $1.4 million sign-on bonus, and it stays marked as reported until another source confirms it.
