Mattel seats its largest holder as another reportedly weighs a proxy fight

Boardroom Alpha · Executive Brief

The largest shareholder of Mattel (MAT) has a seat on the board and has agreed to back the board’s nominees at next year’s annual meeting. On October 21 Mattel appointed Lee Matheson, a partner at the Toronto fund manager EdgePoint Investment Group, under a cooperation agreement, a pact that gives an investor a board role in return for limits on what it can do. The firm owns 17.7% of the toy maker, and the board grows to 10. EdgePoint said Mattel invited it to propose a director after CEO Ynon Kreiz left.

Less than two hours before the announcement, Semafor reported that Southeastern Asset Management is considering nominating its own directors to push Mattel toward a sale. Semafor’s sources said Southeastern’s plans could change and no decision had been made. Nine days earlier, Mattel raised the payout its new CEO, Roger Lynch, would get if it is sold, saying only that it acted “following recent external developments.”

The stock closed at $16.95 on October 21, 34% above its September 30 low. Its total return over the past year was −9.9%, against +16.4% for the S&P 500.

EdgePoint must back the board’s nominees but keeps its vote on a sale

The limits on EdgePoint run at least until the 2027 annual meeting and for as long as Matheson serves. Until then it can’t buy more than the 50.5 million shares it owns, nominate directors, run a proxy fight or propose a deal. It must vote the 36.4 million shares it votes alone for the board’s nominees and against any others, and use its “reasonable best efforts” to do the same with the 14.1 million on which it shares the vote. Those 36.4 million shares are 12.7% of Mattel.

On a sale, EdgePoint votes as it likes unless every director, Matheson included, backs the deal. It also keeps a free vote on changes to Mattel’s charter and bylaws and on any poison pill, a defense that makes a hostile takeover costly. On other proposals it votes with a unanimous board unless a proxy advisor disagrees.

Holders with 15% of the stock can call a special meeting, a shareholder vote between annual meetings. EdgePoint can’t call one while the agreement lasts, and Mattel can’t raise that threshold without EdgePoint’s consent until after the 2028 annual meeting. If EdgePoint’s stake falls below 10%, Mattel’s obligations end and Matheson must resign. Mattel will repay up to $500,000 of EdgePoint’s costs. One seat was the median among 163 other cooperation agreements in the past two years, according to Boardroom Alpha data.

Holders have pressed for a sale since May

Southeastern, which holds more than 4% of Mattel, urged the board in a May 7 letter to “explore strategic alternatives,” naming private equity, media companies and rival toy makers as possible buyers. On October 1 the Wall Street Journal reported takeover interest from Authentic Brands Group. Reuters, citing a source, said Authentic was discussing an offer of more than $20 a share, with no formal sale process under way. The stock rose 18.8% that day. Mattel declined to comment, and no bid has been disclosed.

Ariel Investments, which owns 5.4%, asked the board on October 5 to hire an independent adviser and consider asset sales, a merger or a sale. Mattel said it would “consider the views expressed.”

Mattel’s sales were $5.49 billion in the year to June, about where they were in 2021, and its operating margin fell from 13.4% to 7.8% over that time. In the June quarter net sales rose 10%, but Barbie’s gross billings, sales before discounts and allowances, fell 16% from a year earlier. Mattel has spent $1.5 billion on buybacks since 2023, at an average of about $18.53 a share, above the current price. It pays no dividend.

EdgePoint says Mattel invited it to name a director

After Kreiz left, Mattel’s representatives invited EdgePoint to propose a nominee, EdgePoint said in its 13D, filed the morning after the agreement. The firm, founded in 2008 by former Invesco Trimark managers, runs concentrated long-only funds. Since crossing 10% of Mattel in 2019 it had filed only as a passive holder, certifying it wasn’t trying to influence control. The agreement required it to switch to a 13D.

EdgePoint paid about $830 million for its shares, an average of about $16.42 each, near the October 21 close. It raised its holding from 36.2 million shares in March 2025 to 51 million at June 30, 2026, while Mattel’s buybacks shrank the share count. At signing it held about 530,000 fewer. EdgePoint said it bought the stock as “an attractive investment opportunity.” It reserved the right to make proposals on Mattel’s board, capital structure and “strategic alternatives,” which the agreement limits to private talks with the board while it lasts.

Matheson co-founded the Canadian hedge fund Broadview Capital before joining EdgePoint and has sat on the boards of several small Canadian public companies. He chairs the governance committee at Tucows, where EdgePoint owns 19%. Lynch said Matheson’s perspective as a partner of Mattel’s “longstanding and largest shareholder” adds “a new dimension” to the board. Matheson said he would work toward “unlocking Mattel’s intrinsic value for the benefit of all shareholders.”

Mattel changed its CEO and CFO in three weeks

Kreiz resigned as chairman and CEO on September 29 to take a job at another public company. Reuters reported he is joining Paramount Skydance as co-CEO. The board named Lynch, a Mattel director since 2018 who had run Condé Nast since 2019, as chairman and CEO. Diana Ferguson became lead independent director. Director Adriana Cisneros resigned on October 18; Mattel said it was not the result of any disagreement. On October 20 Peter Griffith, Amgen’s former finance chief, succeeded Paul Ruh as CFO and joined the board.

Mattel raised Lynch’s payout if it is sold

On October 12 Mattel amended Lynch’s contract “following recent external developments.” If Mattel is sold or taken over and Lynch loses his job by the end of 2028, his cash severance rises to about $20.6 million (2.99 times salary and target bonus), from about $13.8 million (two times). If Mattel is sold by then, whether or not he leaves, it would also cover, with some limits, the federal excise tax on his sale-related payments, a so-called gross-up. In April the 2026 proxy listed among its pay practices “No excise tax gross-ups on severance or other payments in connection with a change of control” and severance “not greater than 2x.”

The amendment also granted Lynch’s stock awards that day rather than at month-end, as the offer letter had set, with share counts sized as if the stock were at $13. It closed at $16.76, so awards with a $22 million target were worth about $28 million. One award pays out on Mattel’s return relative to the rest of the S&P 500. The offer letter measured it from his start date, but the amendment moved the starting point back to September 30, when his appointment was announced and the stock closed at $12.66, a day before the takeover report.

Lynch’s only open-market purchase of Mattel stock was 8,000 shares in 2019.

Our view

EdgePoint has owned more than a tenth of Mattel for most of the past seven years. A seat puts that long-term owner in the room as the board weighs its options. The terms protect other holders where it matters most: EdgePoint keeps its own vote on any sale the whole board doesn’t back, and the special-meeting threshold can’t rise without its consent until after the 2028 meeting. The agreement also puts most of the largest holder’s votes behind the board’s nominees in 2027, which matters if another holder nominates directors. The board should tell shareholders how it weighed those votes when, as EdgePoint describes it, Mattel invited the nomination.

The board should also explain the October 12 changes to Lynch’s contract, which depart from the pay practices its April proxy listed. Mattel cited only “recent external developments.” Shareholders deserve to know what those developments were. Directors should buy and hold the stock with their own money.
