April 30 (Reuters) - Western Digital Corp WDC.O forecast fourth-quarter results above Wall Street estimates on Wednesday, betting on stable demand for its storage devices from cloud providers, sending shares up 7% in premarket trading.
Demand for cloud computing, driven by advances in AI technology, has boosted investments in data centers that utilize memory chips from manufacturers such as Western Digital.

"Even in a world marked by geopolitical uncertainty and shifting tariff dynamics, one thing remains constant: the exponential growth of data," said CEO Irving Tan.
The data storage products maker expects fourth-quarter revenue to be $2.45 billion, plus or minus $150 million, higher than analysts' estimates of $2.38 billion according to data compiled by LSEG.
It sees adjusted earnings per share to be $1.45, plus or minus 20 cents, compared with estimates of $1.16.
