surged 13% Wednesday after the digital marketing services company posted a stronger-than-expected fourth quarter.

For its quarter ended Dec. 31, earnings rose to $7.1 million, or a dime a share, from the year-ago $4.1 million, or 6 cents a share. Revenue jumped to $60.7 million from the year-earlier $18.5 million.

The results were far stronger than Wall Street had expected. The Thomson First Call analyst consensus projected a nickel-a-share profit on revenue of $55 million.

"We are very pleased with our fourth quarter and full year results, as each of our operating segments had an exceptional quarter and beat our performance goals," said CEO Brian McAndrews. "2004 marked another great year for aQuantive, which recorded strong organic growth of 59 percent and completed a number of strategic acquisitions that improve the long-term outlook of our business. We believe this momentum positions us very well to reinforce our industry leadership position with continued strong revenue growth and profitability in 2005."

aQuantive also offered guidance that Wall Street deemed agreeable, saying it expects a first-quarter profit of 2 cents to 5 cents a share on revenue of $57 million and full-year earnings of 22 cents a share on revenue of $255 million.

On Wednesday, aQuantive added $1.13 to $10.35.
