Super Micro Computer (NASDAQ:SMCI) shares were down 5.75% at $28.68 in pre-market on Thursday, from a prior close of $30.43. The move gave back part of a 9.50% gain on Wednesday, when AI infrastructure stocks rallied after CoreWeave (NASDAQ:CRWV), described in market data as one of the company's largest customers, reported results and raised its 2026 Revenue outlook.

H15 Server Portfolio Now Shipping

Supermicro announced on Wednesday that its H15 generation server portfolio is shipping, powered by 6th Gen EPYC 9006 Series processors from AMD (NASDAQ:AMD), formerly codenamed Venice. The company said the systems deliver up to 33% more cores, 2x PCIe bandwidth and 1.6 TB/s of memory bandwidth per socket. It also reported multiple SPEC CPU world records on its 2U Hyper and CloudDC servers.

The portfolio includes more than 20 systems, such as Hyper, CloudDC, FlexTwin, GrandTwin, Petascale Storage and SuperBlade. Supermicro said it is also expanding rack-scale offerings with Helios, built around AMD Instinct MI455X GPUs, and Helion, built on the latest EPYC CPUs. It cited 1.8x higher tokens per second for frontier-model host nodes versus prior-generation AMD CPUs.

Sector Weakness Weighs on the Group

Chip stocks came under pressure after reports that the board of Nvidia (NASDAQ:NVDA) is weighing the future of its CEO. Nvidia shares were down about 8% in pre-market, while Nasdaq-100 futures fell about 0.9%.

Market data tied the shares' roughly 28% slide over the past month to Nvidia Leadership turmoil, rate-hike fears and data-center politics.

Valuation and Risk Factors in View

Market data showed a forward price-to-earnings ratio near 4.8 and trailing Earnings Per Share of $3.58. It also listed concerns including customer concentration near 44%, gross Margin near 12.7% and negative operating cash flow, along with scrutiny of China export controls. A small insider purchase by a director was also noted. These figures come from market data summaries and not from the company's release.

Nvidia Earnings in Focus

The next major test for AI server names is Nvidia's earnings report on November 17 after the close. Investors will watch whether the reports about its CEO develop and how the group responds. Pre-market quotes may change before the regular session opens.
