May 16 (Reuters) - Autodesk Inc's first-quarter results missed market expectations on sales declines in the Americas and emerging markets, prompting the maker of AutoCAD design software to cut its full-year revenue forecast.
Shares of the company fell 5 percent after the bell. They closed at $39.78 on the Nasdaq on Thursday.
Autodesk said it expects revenue to grow 3 percent in the year ending Jan. 31, 2014, down from the 6 percent it forecast in February.
The company reported revenue of $2.3 billion in fiscal 2013.
"A mixed global economy weighed heavily on our first quarter results," said Chief Executive Carl Bass in a statement.
Autodesk also expects second-quarter adjusted profit of 39 cents to 44 cents per share, and revenue of $550 million to $570 million.
Analysts on average expect earnings of 51 cents per share on revenue of $597 million, according to Thomson Reuters I/B/E/S.
Autodesk's results are in contrast to rival Adobe Systems Inc, the maker of Photoshop and Acrobat software, which raised its full-year adjusted earnings forecast in March as more customers chose its subscription-based model.
Autodesk's first-quarter net income fell to $55.6 million, or 24 cents per share, from $78.9 million, or 34 cents per share, a year earlier.
Excluding items, it reported a profit of 42 cents per share.
Revenue fell 3 percent to $570.4 million at the company, which also counts Ansys Inc, Parametric Technology Corp , Exa Corp and Dassault Systemes SA as competitors.
Analysts expected first-quarter earnings of 45 cents per share on revenue of $583.4 million.
