March 5 (Reuters) – Marvell Technology forecast first-quarter revenue above Wall Street estimates on Thursday, driven by rising demand for custom chips used in data centers, ‌sending its shares surging 9% in extended trading.

Growing adoption of AI tools by enterprise ‌clients has boosted demand for specialized chips that power advanced data centers, benefiting companies such as Marvell and Broadcom that ​design application-specific integrated circuits (ASICs).

Big Tech firms including Alphabet, Microsoft, Amazon and Meta are expected to spend at least $630 billion to build AI infrastructure this year, lifting demand for chips used in servers and networking equipment from companies such as Marvell.

Marvell expects revenue of around $2.40 billion, plus or minus 5% for the first ‌quarter, above analysts’ average estimate of $2.27 ⁠billion, according to data compiled by LSEG.

The company said the forecast includes expected results of Celestial AI and XConn Technologies.

The Santa Clara, California-based company divested ⁠its automotive ethernet business last year and completed the acquisition of Celestial AI in a deal worth $3.25 billion, doubling down on photonic fabrics, technology that uses light rather than electrical signals to connect AI ​chips and ​memory chips.

“We expect year-over-year revenue growth to accelerate each ​quarter in fiscal 2027, driven by ‌continued strength in our data center business, with bookings continuing to grow at a record pace,” CEO Matt Murphy said in a statement.

Marvell and rival Broadcom help cloud-computing companies design custom chips tailored to their data-center workloads, a fast-growing business as hyperscalers seek alternatives to Nvidia‘s general-purpose AI processors.

“Marvell’s shares like many AI-related names have underperformed the semiconductor group in the past two quarters. We ‌think the better-than-expected results and outlook, while expected, is ​more of a relief for investors than confirming the near-term ​data center spending strength,” said Kinngai ​Chan, senior research analyst at Summit Insights.

Broadcom on Wednesday said it expected over $100 ‌billion in AI chip sales next year, ​signaling rapid share gains in ​a market dominated by Nvidia, which last month reported better-than-expected results for the January quarter.

For the fourth quarter, Marvell reported a 22% increase in revenue to $2.22 billion, slightly above ​estimates of $2.21 billion. Adjusted earnings ‌per share of 80 cents beat estimates of 79 cents.
