Yahoo said fourth-quarter revenue was $1.266bn, compared to $1.346 billion in the year-ago quarter.
Yahoo said that revenue from display ads was down 6pc year-over-year in the fourth quarter, while the price per ad, excluding Korea, declined 7pc.
Net income of $348.2m rose from the $272.3m earned in the year-ago period. Excluding certain items, Yahoo said it earned 46 cents a share, beating the average analyst expectation of 38 cents, according to Thomson Reuters I/B/E/S.
