Super Micro Falls 4% as NVIDIA Probe Drags Down AI Server Stocks

Super Micro Computer stock fell 4% to $27.39 on November 10, dragged down by a second straight day of selling at NVIDIA — its most important chip supplier and the anchor of the entire AI server trade.

The damage spread fast across the group. Dell Technologies dropped 6% to $326.57. Hewlett Packard Enterprise declined 2% to $46.45, the smallest loss of the three. NVIDIA itself traded at $167.51, down 6% in afternoon trading.

The selling started at the top of the chain. According to CNBC, NVIDIA's board is investigating CEO Jensen Huang's relationship with an alleged Chinese spy, and investors spent a second day repricing that risk. On November 9, NVIDIA stock fell even as the broader market rose. China has rejected the spying allegations as "slander and smearing," per CNBC's reporting from Beijing.

For companies like Super Micro, the connection is mechanical. The server builder constructs its rack-scale systems around NVIDIA's graphics processing units, so trouble at the chipmaker tends to land quickly on the hardware makers below it. Uncertainty at the top of that chain spreads down through supply relationships and customer confidence alike.

Why does one chipmaker's problem hit the whole server group?

Super Micro Computer (NASDAQ: SMCI) builds complete racks and liquid-cooled systems around NVIDIA GPUs. That architecture — the company's Data Center Building Block Solutions, or DCBBS — gives it more direct exposure to NVIDIA's product cycle than either of its larger peers carries. Manufacturing in the U.S., Taiwan and the Netherlands lets Super Micro ship at scale to large cloud and enterprise customers.

CNBN's reporting added a political dimension to the market anxiety: Huang is seen as having tremendous influence with President Trump, including on the approval of NVIDIA's H200 chip. If that relationship comes under scrutiny while NVIDIA's board investigates his ties, the political channel that helped NVIDIA's chip approvals could become a liability rather than an asset.

Macro pressure compounded the chip-specific news. October's Consumer Price Index came in hotter than expected, lifting expectations for higher interest rates from the Federal Reserve. Higher-rate expectations tend to weigh hardest on high-flying tech names, and AI server stocks fit that profile.

The stakes here are straightforward. The AI server business has been one of the market's strongest performers for two years, and its profitability depends on steady NVIDIA supply. A board investigation involving the CEO of that supplier — with a potential fight with Beijing in the background — puts a question mark over the entire group's near-term outlook.

What do the numbers say about each company?

The daily moves hide a valuation picture that splits the three companies in sharp ways.

• Super Micro Computer trades at a trailing price-to-earnings ratio of 8x, the group's lowest. Yet it's the only one of the trio down for the year, off 6% year to date.
• Dell Technologies carries a higher but still moderate trailing P/E of 18x. Even after the slide, Dell stock is up 162% year to date.
• Hewlett Packard Enterprise shows a trailing P/E of 1,107x on GAAP earnings — a figure weighed down by Juniper Networks acquisition costs, so it doesn't screen as cheap on that measure. HPE stock is up 96% year to date.

Super Micro's profit numbers make its stock performance look even stranger. The company reported net income of $1.178 billion for Q4 FY2026 on August 11, according to its SEC filing. That gap between strong profits and a falling share price is one reason the valuation picture across the AI server group looks more mixed than it first appears.

How do the three businesses actually differ?

Super Micro is the purest AI infrastructure play of the three. It sells complete racks and liquid-cooled systems through its DCBBS architecture, and that focus cuts both ways: it captures more of the AI buildout, but it also absorbs more of any NVIDIA disruption.

Dell runs a broader enterprise IT platform. It pairs AI-optimized servers, storage and networking with a large personal computer business, giving it revenue streams that don't depend on the GPU cycle.

Hewlett Packard Enterprise leans hardest on networking after absorbing Juniper Networks. The company added routing, campus and data center switching and security alongside its servers, storage and financial services. That smaller AI server weighting relative to Super Micro or Dell may help explain why HPE posted the group's smallest drop on November 10.

What happens next for Super Micro?

The company now faces a single overriding question: does NVIDIA's board investigation stay contained, or does it broaden into a wider fight with Beijing? The answer will shape the next several months for every server maker tied to NVIDIA silicon.

Both sides of the Super Micro trade can find support in the company's November 3 earnings call. Bulls can point to management's fiscal 2027 revenue target of $72 billion to $82 billion. Bears have an offset from the same call: Super Micro disclosed that one customer accounted for 44% of quarterly revenue. Chief financial officer Mark Long called that concentration "a consequence of the scale at which AI infrastructure is now being built."

That concentration cuts both ways. A single hyperscale customer spending at that level validates demand. It also means one customer's hesitation — or one disrupted NVIDIA supply relationship — could move Super Micro's revenue in ways its peers wouldn't feel.

Dell and Hewlett Packard Enterprise both have quarterly reports coming up. Those results will show whether AI server orders are holding up through the NVIDIA turmoil, or whether customers are pausing purchases until the investigation resolves.

The scenarios split cleanly. A quick resolution at NVIDIA could ease pressure on the whole group. A drawn-out probe might keep weighing on server makers, especially those with the highest direct NVIDIA exposure. As 24/7 Wall St. noted in its analysis, how heavily each server maker depends on NVIDIA while the investigation plays out will be the key question — and for now, it's wise to keep position sizes small in SMCI, DELL, and HPE.

The November 10 selloff was a single trading day. The NVIDIA board investigation, and the customer-concentration questions underneath it, will take much longer to answer.
