ELECTRONIC ARTS UPDATES FISCAL YEAR 2005 ESTIMATES

REDWOOD CITY, CA – March 21, 2005 – Electronic Arts (NASDAQ: ERTS) today announced revised estimates for the Company’s fiscal year ending March 31, 2005. The changes are primarily the result of lower than expected sales in both North America and in Europe.

The Company now expects fiscal year 2005 net revenue to be between $3.100 and $3.125 billion, as compared to the Company’s previous estimate of between $3.275 and $3.325 billion.

Non-GAAP diluted earnings per share are now expected to be between $1.70 and $1.72 as compared to the Company’s previous estimate of $1.90 to $1.95.

GAAP diluted earnings per share are now expected to be between $1.62 and $1.64 – as compared to the Company’s previous estimate of $1.82 to $1.87.

“These results are clearly disappointing,” said Larry Probst, Chairman and Chief Executive Officer. “While our new releases are performing reasonably well, they have not been able to offset a significant falloff in catalog sales.”

Non-GAAP Financial Measure

Electronic Arts’ estimate of non-GAAP diluted earnings per share excludes the following items from its estimate of GAAP diluted earnings per share, including any related tax effects:

• Amortization of intangibles

• Employee stock-based compensation

• Restructuring and asset impairment charges

• Charges for acquired in-process technology

• Other-than-temporary impairment of investments in affiliates

The Company believes that excluding these items is useful for illustrating and explaining operating results and comparisons to prior periods. Management considers this non-GAAP measure in its decision-making to facilitate more relevant operating comparisons.
