Oct 29 (Reuters) - Gorilla Glass maker Corning

fourth-quarter profit forecast beat estimates on Tuesday, as

rising consumption of data over networks, including for

generative AI model training, continues to increase demand for

its optical fiber products.

Shares of the company were up 4.8% in premarket trading.

A shift in data consumption patterns, including cloud

computing and the proliferation of video content, has led to an

increasing need for fast data transfer via optical fiber cables.

This demand is further driven by the use of data generated by

consumers and enterprises to train AI models.

The New York-based company also said on Monday it struck a

$1 billion multi-year deal with AT&T ( T ) to supply fiber,

cable and connectivity solutions for expanding high-speed

internet services.

Corning expects fourth-quarter revenue of $3.75 billion,

which beat analysts' expectations of $3.67 billion, according to

data compiled by LSEG.

On an adjusted basis, it forecasts earnings per share of

between 53 cents and 57 cents, compared with Wall Street

estimates of 52 cents.

The company reported revenue of $3.73 billion for the

quarter ended Sept. 30, exceeding Wall Street estimates of $3.71

billion. It earned a profit of 54 cents per share, compared with

analysts' expectations of a profit of 52 cents per share.
