Yahoo!, owner of the second-ranked US Internet search engine, reported profit that topped analysts’ estimates, bolstered by a rebounding online advertising market and the sale of its Zimbra business.

First-quarter net income attributable to Yahoo more than doubled to $310.2 million, or 22 cents a share, from $117.6 million, or 8 cents, a year earlier, the company said in a statement.

Analysts had estimated only 9 cents per share on average.
