July 28 (Reuters) – Seagate Technology forecast quarterly revenue and profit above estimates on Tuesday, as the ‌rapid buildout of AI infrastructure fuels robust demand ‌for its high-capacity hard disk drives.

Shares of the Singapore-based company, which ​have more than doubled this year, rose over 8% in extended trading.

Here are some details:

• Seagate has leveraged its heat-assisted magnetic recording (HAMR) technology, which uses tiny lasers to ‌help pack more data ⁠onto each disk, allowing it to boost hard-drive capacity and storage without building costly ⁠new manufacturing lines.

• The company expects first-quarter revenue of $4.1 billion, plus or minus $100 million, above analysts’ average estimate of $3.75 ​billion, ​according to data compiled by ​LSEG.

• Adjusted profit is ‌expected to be $7.30 per share, plus or minus 20 cents. On average, analysts expect $5.80 per share.

• “As AI accelerates data generation and its value, we see durable long-term demand for mass capacity storage,” CEO Dave Mosley said.

• ‌The results cap a strong year ​for Seagate, on the back ​of surging demand ​for its HDDs as large cloud companies ‌build out the vast storage ​infrastructure required to ​support generative AI applications, allowing the company to raise prices.

• Fourth-quarter revenue rose 48.5% to $3.63 billion, beating ​estimates of $3.49 ‌billion. Adjusted profit came in at $5.71 per share, compared ​with estimates of $5.09.
