NEW YORK -- Shares of Informatica Corp. tumbled Thursday after the business software maker forecast weak results in the third quarter, pointing to its struggling business in Europe.

Informatica said it expects adjusted net income of 25 to 27 cents per share and $189 million to $191 million in revenue in the third quarter. It said its operations improved in the U.S. and the Asia-Pacific region, but results in Europe fell short of its expectations.
