(Reuters) -Shares of Marvell Technology slumped nearly 18% on Friday, as the chipmaker's data center demand outlook fell short of lofty expectations owing to irregular sales of its custom AI chips to cloud giants.
Investor expectations for chipmakers are elevated after their valuations have sky-rocketed due to Wall Street's picks-and-shovels AI trade, but market bellwether Nvidia‘s latest earnings cast doubt over demand from cloud providers.
Marvell CEO Matt Murphy said on a post-earnings call on Thursday that data center revenue in the third quarter would be sequentially flat, worrying investors and analysts about growth in its key segment that reflects demand for hardware used in AI data centers.
The networking chipmaker's revenue is increasingly driven by its custom chip business which services cloud providers such as Amazon.com and Microsoft who are developing in-house capabilities to reduce their dependence on Nvidia.
A recent media report said Microsoft had delayed its in-house AI chip rollout to 2028 or later.
Some analysts said the concerns were overblown.
Morningstar analyst William Kerwin said the delay could benefit Marvell by increasing Microsoft's reliance on it.
“Overall, the most important debate on Marvell stock today is uncertainty in its ability to retain its custom chip business, across both AWS and Microsoft. We are more bullish on this front.”
Murphy said “lumpiness” was normal when large cloud providers build infrastructure, referring to Marvell's exposure to uneven product development schedules and spending.
Summit Insights analyst Kinngai Chan, who has a “hold” rating on the stock, said, “Marvell lacks scale relative to larger peers and expects hyperscale customers to pursue a multi-vendor sourcing strategy, which could weigh on margins.”
Marvell competes against larger rival Broadcom for a piece of cloud providers' custom chip and networking businesses. Broadcom is yet to report July quarter results.
Marvell is set to lose close to $12 billion in market value if losses hold. It has a 12-month forward price-to-earnings ratio of 24.24, compared with Broadcom's 39.03, according to data compiled by LSEG.
But Marvell expects its custom business to be stronger in the fourth quarter, Murphy said, implying an uptick later in the year as custom chip orders increase again.
