Q1 Financial Summary

Google's results for the quarter ended March 31, 2008, include the operations of DoubleClick Inc. from the date of acquisition, March 11, 2008, through the end of the quarter, and are compared to pre- acquisition results of prior periods. The overall impact of DoubleClick in the first quarter of 2008 was immaterial to revenue and only slightly dilutive to both GAAP and non-GAAP operating income, net income and earnings per share.

Google reported revenues of $5.19 billion for the quarter ended March 31, 2008, an increase of 42% compared to the first quarter of 2007 and an increase of 7% compared to the fourth quarter of 2007. Google reports its revenues, consistent with GAAP, on a gross basis without deducting traffic acquisition costs, or TAC. In the first quarter of 2008, TAC totaled $1.49 billion, or 29% of advertising revenues.

Google reports operating income, net income, and earnings per share (EPS) on a GAAP and non-GAAP basis.
