After subtracting the commissions paid to its advertising partners, Yahoo’s revenue totaled $1.09 million, about $10 million above analyst estimates. The company released the results after the stock market closed. Yahoo shares gained 33 cents to finish at $31.30 on the Nasdaq Stock Market, then added $1.92, or 6.1 percent, in extended trading. Yahoo’s robust revenue growth led many investors to conclude that online search engine leader Google Inc. will turn in strong numbers when it releases its first-quarter results Thursday. Google’s shares decreased $2.58 to close at $404.24 on the Nasdaq, then rose $11.56, or 2.9 percent, in extended trading. Before its first-quarter announcement, Yahoo’s market value had declined by 20 percent so far this year, reflecting concerns raised by research reports indicating that the company has been steadily losing search-engine market share to Google. The data from both comScore Media Metrix and Nielsen/NetRatings troubled investors because Internet search engines have become the Web’s biggest advertising vehicle. ComScore raised another red flag this week with a report estimating that Google’s U.S. market share had climbed to 42.7 percent in March, up from 36.4 percent last year, while Yahoo’s had shrunk to 28 percent from 30.6 percent last year. But Susan Decker, Yahoo’s chief financial officer, challenged those findings in a Tuesday conference call. She told analysts usage of Yahoo’s search engine in the past quarter increased by 15 percent to 20 percent from last year.160Want local news?Sign up for the Localist and stay informed Something went wrong.

Yahoo said the accounting change lowered its earnings by $71 million in this year’s first quarter versus $6 million a year ago. If not for the stock-option expenses and other one-time gains, Yahoo said, its profit for the just-ended quarter would have improved by 18 percent over the same period last year. Analysts polled by Thomson Financial had factored the new accounting rules into their average estimate of 11 cents per share. Revenue for the period totaled $1.57 billion, a 34 percent increase from last year. SAN FRANCISCO – Yahoo Inc.’s first-quarter profit met analyst expectations Tuesday, relieving investors who feared that losses in the Internet powerhouse’s search-engine market share might hinder its advertising growth. Yahoo shares surged more than 6 percent on the news. The Sunnyvale-based company said it earned $159.6 million, or 11 cents per share, during the first three months of the year. That represented a 22 percent decrease from net income of $204.6 million, or 14 cents per share, at the same time a year ago. It wasn’t an apples-to-apples comparison because of new rules requiring companies to recognize the costs of their employee stock options.
