Shareholder pressure on Mattel to explore a sale intensified after Ariel Investments, which holds a 5.4% stake, joined calls for a review of strategic options, according to a Reuters report published in October. Ariel said the toymaker's shares remained significantly undervalued, citing that assessment in its call to explore a sale. Southeastern Asset Management had previously called for alternatives to the company's ownership to be explored, according to a Reuters report published in May. The alternatives Southeastern proposed included taking the company private or an acquisition by rival Hasbro. The public calls thus broadened from Southeastern's earlier appeal to pressure involving Ariel and its equity stake.

In Longleaf's third-quarter fund commentary, Southeastern criticised Mattel's reset of earnings expectations, describing it as an "ill-advised reset of earnings expectations". In the same commentary, it said reports had indicated interest from several potential buyers since the end of the quarter. It also noted that Mattel shares had been a significant contributor to the fund's returns in October up to the time the investor commentary was written. It confirmed its continued dialogue with the company, saying: "We continue to engage with the company." The asset manager's position combined criticism of a decision on earnings expectations with references to potential takeover interest, while maintaining its dialogue with Mattel.

Authentic Brands Group was among those that expressed takeover interest, according to a Reuters report published in early October, citing a person familiar with the matter. The person said discussions of takeover interest included a price above $20 per Mattel share. Reuters reported at the time that no formal sale process was under way, despite the interest discussed. In trading linked to the shareholder demands, Mattel shares fell about 3% in the Tuesday session following Ariel's call to explore strategic alternatives, according to the agency's October report. That decline followed Ariel's letter, while the potential takeover price was attributed to the person familiar with the matter in the report on Authentic Brands' interest.

On financial performance, Mattel reported that net sales in the second quarter of 2026 rose to $1,125 million, an increase of 10% from a year earlier on a reported basis. But the company posted a net loss of $18 million for the same period, according to its quarterly earnings release. It had reported net income of $53 million in the second quarter of 2025, the year-earlier comparison cited by the company. Reported sales growth thus coincided with a swing from profit to loss between the two periods. Those results formed the financial backdrop to calls to explore a sale, which also coincided with Southeastern's criticism of the reset of earnings expectations.

Mattel's second-quarter results filing with the U.S. Securities and Exchange Commission showed adjusted gross margin fell to 48.6%. The decline was 260 basis points from the corresponding period, according to the filing, despite the year-on-year increase in net sales. The company attributed the margin decline to a range of cost pressures, including gross incremental tariff costs and inflation. It added higher royalties to the factors weighing on margin, alongside unfavourable foreign exchange effects. Mattel cited these factors in explaining the decline in second-quarter adjusted margin, a period that also saw it post a net loss compared with a profit a year earlier.

In its response to Southeastern's letter, Mattel said its board "will continue to consider the views expressed in Southeastern's letter". The company said its strategy focused on growing its intellectual property-driven play and family entertainment businesses. That position stands against the alternatives proposed by the investor, including taking the company private or an acquisition by Hasbro. At board level, Mattel announced the appointment of current director Dianna Ferguson as its new lead independent director. Ferguson's appointment was included in the company's announcement on the leadership transition to Roger Lynch, as investors continued to call for a review of the company's future ownership.

Mattel's board set a deadline of 2 November 2026 for Roger Lynch to take over as chief executive, according to the company's announcement. The announced timing allows him to begin his duties on or before that date as part of the board-approved leadership transition. The next financial reporting milestone follows, with Mattel planning to announce its third-quarter 2026 results on 5 November. The company scheduled the release for approximately 4:05 p.m. U.S. Eastern Time, according to its announcement of the reporting date. The forthcoming quarterly disclosure follows second-quarter results that combined sales growth with weaker profitability, amid shareholder calls to explore a sale and the board's continued consideration of Southeastern's letter.
