(Yahoo! story updated to correct a misreported revenue comparison and to provide further information from the company's earnings release.)SUNNYVALE, Calif. ( TheStreet) -- Yahoo! ( YHOO) squeaked past analysts' estimates with a per-share profit of 15 cents in the second quarter, but the stock came under pressure after hours as investors reacted to a disappointing top-line figure. Revenue in the quarter ended June 30 amounted to $1.6 billion, Yahoo! said, up slightly from last year's $1.57 billion. But after subtracting about $470 million in so-called "traffic acquistion costs," the company's net revenue was $1.13 billion, less than the $1.16 billion that analysts were expecting. ( An earlier version of this story incorrectly compared the consensus revenue forecast with Yahoo's revenue including traffic acquisiton costs.) Investors sold off Yahoo! shares in after-hours trading Tuesday. The stock was changing hands at $14.54, down 74 cents, or 4.9%, from its close in the regular session. A year ago, the company earned 10 cents a share. Looking ahead, Yahoo! said it expects to post third-quarter revenue of $1.57 billion to $1.65 billion. Taking into account traffic-acquistion costs, however, Yahoo!'s projected revenue for the third period comes to $1.1 billion on the low end and $1.17 billion on the high end. Analysts had been expecting about $1.16 billion, according to a survey of the sell side by Thomson Reuters. Yahoo! said income from operations for the third quarter would likely fall between $160 million and $200 million. -- Written by Scott Eden in New York Follow TheStreet.com on Twitter and become a fan on Facebook.
