Southeastern Asset Management Issues Open Letter Calling on Mattel
to Explore Strategic Alternatives
MEMPHIS, Tenn., May 7, 2026 (BUSINESS
WIRE) -- Southeastern Asset Management, Inc. (“Southeastern”) today issued an open letter to the board of directors and shareholders
of Mattel, Inc. (NASDAQ: MAT) (“Mattel” or the “Company”), calling on the Company to explore strategic alternatives.
The full text of the letter is below.

Open Letter to the Board and Shareholders of Mattel, Inc.
Southeastern Asset Management, Inc. manages on behalf of its clients over
4% of Mattel’s common stock. We are sharing this letter with the Board and other shareholders as a continuation of a conversation
we began with CEO Ynon Kreiz in mid-March, when we sent him the following:
Ynon,
As you know, Southeastern has been a supportive Mattel investor for over
eight years. We are grateful for your leadership that stabilized the business during a difficult period. We believe Mattel now has a solid
balance sheet and a strong set of brands that should grow free cash flow per share in aggregate beyond 2026. However, after more thought
since our last meeting, we believe that now is the time for the Company to explore strategic alternatives. We believe there are at least
three groups of buyers of Mattel that would be better owners to realize long-term value:
| 1. | Private equity buyers have circled Mattel in the last few years. Mattel’s business does not always lend itself well to the quarterly
results stability that the public equity market prefers. We also wonder how Mattel’s controversial $150 million of investment spending
in 2026 would go if the company were private – maybe even more spending, maybe less? We believe this is a cash-generative business
that can support a larger amount of leverage when it doesn’t have to worry about quarterly results and annual guidance. |
| 2. | The most logical strategic buyer of Mattel is likely another “toy” company. We put “toy” in quotes as the
industry has a broad spectrum, and Mattel itself is not and should not be focused only on selling physical items. We know that Mattel
and Hasbro have engaged in on-and-off talks for decades. At the moment, a deal between the two companies is possible in our view. Hasbro
has done a better job executing on digital growth than Mattel and therefore has more credibility in this important part of the business.
We believe synergies between the two companies would be material, creating a stronger player in a global industry. There are also other
toy companies of size around the world who would be interested in Mattel. A smaller sale of Fisher-Price only (after its years of underperformance)
in order to print a better consolidated growth rate is not sufficient for Mattel to realize its potential. |

| 3. | Now that the dust has settled from the Warner bidding war, large media companies are looking for their next moves. Mattel has valuable
intellectual property that we believe would fit well with one of these entities. The public market was not willing to pay for the success
of the Barbie movie and might not be willing to pay for a pipeline of other content at Mattel, but a media company would value these assets. |
These three categories are not mutually exclusive: a toy company might
not want to make movies or a media company might not want to make toys, all while certain private equity buyers might only want certain
parts of Mattel. There are creative solutions to maximize value for shareholders if Mattel actively explores the landscape.
We worry that your current compensation package incentivizes waiting too
long for a stock price over $30. We see a value per share today approaching $30, but we do not want to wait longer for that to be realized.
We would prefer you lead the effort to explore strategic alternatives given your industry knowledge and relationships.
Sincerely,
Southeastern Asset Management, Inc.
