Shares of

Jamdat Mobile

(JMDT)

zoomed up more than 10% Thursday afternoon after the wireless game and ring-tone vendor's report beat the Street's earnings expectations and offered a bullish outlook.

Excluding certain items, the company's first-quarter earnings came in 4 cents a share better than analysts had predicted. Meanwhile, the company said earnings would be better than the Street's forecasts for the second quarter, its full year and for 2005.

After Jamdat's report, which came after the bell, the company's stock rose $1.82, or 10.4%, to $19.33.

In the first quarter, Jamdat earned $2.7 million, or 13 cents a share. That was up markedly from $738,000, or the 17 cents per-share profit the company posted in the year-ago period. Between the two reports, the company completed its initial public offering, and its share count jumped from 4.5 million to 21.1 million.

The company tallied $15.1 million in sales in the first quarter, up 31% from the fourth quarter and more than double the $7 million in revenue it reported in the year-ago period.

Excluding stock-based compensation, amortization of intangibles and acquired in-process development expenses, the company would have earned $3.6 million, or 17 cents a share, in the just-completed quarter.

On this basis, analysts polled by Thomson First Call had been expecting the company to earn 13 cents a share on $15 million in sales. Last month, the company

preannounced that it would post $15 million in sales for the quarter and that its earnings would come in higher than its forecast of 8 cents per share -- or 13 cents per share sans expenses.

In its second quarter, Jamdat expects to earn 12 cents a share -- or 18 cents on a non-GAAP basis -- on $19 million in sales. For all of 2005, the company predicted earnings of 55 cents a share -- 76 cents a share non-GAAP -- on sales of $80 million. Looking even further out, the company forecast that its 2006 earnings would come in at around 75 cents a share -- $1.05 a share not including expenses -- on $120 million in sales.

Excluding items, the Street had predicted that the company would earn 13 cents a share on $17.68 million in sales in the current quarter and 62 cents a share on $79 million in sales this year. For 2006, the Street had forecast 80 cents a share in non-GAAP earnings on sales of $109.11 million.

The rise in Jamdat shares after the bell followed an already strong day for the stock. The company's shares ended regular trading up 76 cents, or 4.5%, to $17.51.
