Google's 3Q earnings rise 36 percent, stock surges October 17, 2013 at 8:06 PM CDT - Updated July 21 at 6:33 AM SAN FRANCISCO (AP) - Google's earnings climbed 36 percent despite a deepening slump in its average ad prices as more people connect to its search engine and other services on mobile devices. The results released Thursday exceeded the analyst projections that steer investors. Google's stock surged 6 percent to $943.90 after the numbers came out. Google Inc. earned nearly $3 billion, or $8.75 per share, during the three months ending in September. That compared to income of $2.2 billion, or $6.53 per share, at the same time last year. The Mountain View, Calif. company's average ad price has declined from the prior year in each of the last eight quarters primarily because advertisers aren't yet paying as much for mobile ads. Revenue rose 12 percent from last year to $14.9 billion. Copyright 2013 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
