EL SEGUNDO, Calif., July 17, 2006 – Mattel, Inc. (NYSE: MAT) today reported 2006 second quarter financial results. For the quarter, the company reported net income of $37.4 million, or $0.10 per share, compared to last year’s second quarter net loss of $94.0 million, or $0.23 per share. Net income for the quarter was positively impacted by tax benefits of approximately $6.2 million, or $0.02 per share, primarily relating to an audit settlement with a state tax authority. Last year’s net loss was significantly impacted by incremental tax expense of $112.9 million, or $0.28 per share, resulting from the company’s decision to repatriate $2.4 billion in unremitted foreign earnings under AJCA.

“We are pleased with our second quarter results. As expected, we benefited from our summer entertainment toy lines based on the CARS and Superman™ movies, as well as the newest American Girl Place in Los Angeles,” said Robert A. Eckert, chairman and chief executive officer of Mattel. “We also experienced the second consecutive quarter of growth in the U.S.

for the Barbie brand. While I am pleased with Barbie’s progress thus far, we are still in the process of implementing a variety of enhancements for the brand over the next year.”

Financial Overview

For the quarter, net sales were $957.7 million, up 8 percent compared to $886.8 million last year, with no impact from changes in currency exchange rates. On a regional basis, second quarter gross sales increased 5 percent in the U.S., and were up 12 percent in international markets, including favorable changes in currency exchange rates of 1 percentage point. Operating income for the quarter of $49.9 million increased from $28.5 million in 2005 primarily due to the growth in net sales.

The company’s debt-to-total-capital ratio was 31.1 percent. In the quarter, the company issued $300 million of senior notes. Due to the normal seasonality of the business, the company’s cash and equivalents declined by approximately $373 million during the six months ended June 30, 2006, compared with a decline of approximately $795 million in the prior year period. During the second quarter, the company repurchased 9.4 million shares of its common stock at a cost of $153.3 million.

Sales by Business Unit

Mattel Girls and Boys Brands

For the second quarter, worldwide gross sales for the Mattel Girls and Boys Brands business unit were $609.6 million, up 8 percent versus a year ago. Worldwide gross sales for the Barbie^® brand were down 1 percent. Worldwide gross sales for Other Girls Brands were down 1 percent, despite continued growth from the Pixel Chix™ and Polly Pocket!™ toy lines. Worldwide gross sales for the Wheels category, which includes the Hot Wheels^®, Matchbox^® and Tyco^® R/C brands, were down 6 percent. Worldwide gross sales for the Entertainment business, which includes Games and Puzzles, were up 38 percent for the quarter primarily due to the launch of the CARS and Superman™ toy lines.

Fisher-Price Brands

Second quarter worldwide gross sales for the Fisher-Price Brands business unit, which includes the Fisher-Price^®, Little People^®, Rescue Heroes^® and Power Wheels^® brands, were $365.7 million, or up 8 percent versus the prior year. This reflects strong growth in Core Fisher-Price^® and the Power Wheels^® brand worldwide, as well as strong growth in Fisher-Price^® Friends in international markets.

American Girl Brands

Second quarter gross sales for the American Girl Brands business unit, which offers American Girl^® branded products direct to consumers, were $61.6 million, up 5 percent versus last year primarily due to sales from the third American Girl Place store, which opened in Los Angeles in April 2006.
