Sept 12 (Reuters) -

U.S. chemicals maker Dow lowered its third-quarter

revenue forecast on Thursday due to an unplanned event at one of

its plants in Texas.

The company's CEO, Jim Fitterling, said a significant

unplanned event occurred in late July at one of its ethylene

crackers in the Texas plant.

Dow is also experiencing higher input costs and margin

compression in Europe, he added.

The company expects its third-quarter revenue to be

approximately $10.6 billion, compared with the prior view of

$11.1 billion.

Wall Street estimated a revenue of $11 billion for the third

quarter.

Shares of the company fell 2.9% in premarket trading.
