Shares of Adobe Systems Inc. (NASDAQ: ADBE) are trading slightly higher in today's premarket action, following yesterday evening's fourth-quarter earnings release. The company posted a pretty strong quarter, but investors have displayed some concerns over the company's 2008 outlook, which was left unchanged.

The company reported a growth of 21% for its quarterly profit, which rose up to $222.2 million, or 38 cents a share, following strong sales of its design software. Back a year ago, Adobe had posted a profit of $183.2 million, or 30 cents a share, in the same period.

Included in the company's figures were certain costs related to stock-based compensation and restructuring charges. Excluding that, the company''s profit was 49 cents per share. Analysts had been expecting to see the Adobe show earnings of 37 cents per share.

If you take a look at revenues, you see a very respectable jump of 34% in the quarter, helped by increased sales of software for photo editing, building Web sites and creating graphics. The maker of Photoshop, Flash and Illustrator software posted record sales of $911.2 million, easily beating analysts' expectations for sales of $887.33 million.
