Yahoo reported a 93 percent slide in quarterly profit from a year ago, while revenues rose modestly in disappointing quarterly results for the struggling Internet pioneer. Net profit for the first quarter tumbled to $21.1 million from $312 million in the same period last year, amid what chief executive Marissa Mayer called "encouraging revenue growth" of eight percent. Total revenue for the first three months of the year grew to $1.23 billion, led by gains in "search revenue," from ads linked to queries using Yahoo's search function. But revenue and profit were both lower than Wall Street forecasts. "Yahoo is amid a multi-year transformation to return an iconic company to greatness," Mayer said in the earnings statement. "This quarter, we saw encouraging revenue growth of 8 percent, with display revenue growing a modest 2 percent and search growing 20 percent." She said mobile revenues reached $234 million in the quarter, up 61 percent from a year ago. The Internet giant will now focus on "accelerating" revenue growth "while managing our margins and costs," Mayer said. She disclosed that Yahoo cut some 1,100 jobs in the past quarter, bringing the number of reductions to some 3,000 over the past three years. Yahoo has been under pressure from activist shareholders to deliver more value with lower costs and a narrower focus. In the past quarter, expenses were sharply higher, due to increased product development spending and restructuring expenses. The group has been undergoing a major reorganization since Mayer took the helm in 2012.
