General Electric Company (NYSE:GE) boosted its third-quarter profit 8.3 percent rise as strong U.S. and Asian demand for electric turbines and railroad locomotives helped offset weakness in the company's European business.

Profit climbed to $3.49 billion, or 33 cents per share, from $3.22 billion, or 22 cents per share, a year earlier. Excluding one-time items, the Fairfield, Conn., industrial conglomerate earned 36 cents per share. Revenue rose 2.8 percent to $36.35 billion from $35.36 billion.

"The global economy is uncertain, and we are prepared for a variety of economic outcomes," CEO Jeff Immelt said in a statement.

Shares fell 41 cents to $22.40 in premarket trading.
