Yahoo revenue tops Wall Street forecasts SAN FRANCISCO Yahoo's fourth-quarter earnings topped analyst estimates as an upturn in its international investments helped end a three-year slump in revenue. The results announced Monday covered Yahoo's first full quarter under CEO Marissa Mayer. Yahoo lured Mayer away from Google a former top Google (GOOG) executive in mid-July. Mayer has been focusing on building better mobile and social networking services so Yahoo can make more money from two of technology's hottest trends. The company's fourth-quarter earnings dipped 8 percent from the previous year to $272 million, or 23 cents per share. The earnings would have been higher than the previous year, if not for one-time accounting charges. Yahoo's fourth-quarter revenue increased 2 percent from the previous year to $1.35 billion. It left Yahoo with its first revenue gain for the full year since 2008. Yahoo reported search revenue of $482 million for the quarter, up 4 percent over the year-ago period.
