AMD and Super Micro Shares Slide as AI Growth Expectations Dim After Data Center Results Miss

/in /tarafından

Shares of Advanced Micro Devices (AMD.O) and server maker Super Micro Computer (SMCI.O) fell sharply in early trading Wednesday after both companies reported weaker-than-expected results in their data center segments, casting doubt on their AI growth prospects and competitive standing. AMD shares dropped 5.1%, while Super Micro plummeted 18.2%, with the latter potentially losing over $6 billion in market value.

AMD’s data center revenue, driven by Instinct AI chips and server CPUs, grew 14% to $3.2 billion in Q2—slightly below analyst forecasts—and lagged far behind rival Nvidia’s 73% jump to $39.11 billion in the same segment. Jefferies analysts said the AI outlook failed to deliver the strong upside some investors anticipated. CEO Lisa Su cited U.S. export restrictions on AMD’s MI308 AI chips to China as a factor in year-over-year AI revenue declines, with no clear timeline for lifting those limits. HSBC noted that expectations for revenue recovery from lifting export restrictions appear muted.

The chip sector faces additional risks from impending U.S. tariffs on semiconductor imports and supply chain vulnerabilities tied to Taiwan Semiconductor Manufacturing Company (TSMC), which produces AMD’s advanced 3-nanometer wafers. Analyst Michael Ashley Schulman warned any slowdown at TSMC could disproportionately impact AMD.

Super Micro missed Q4 estimates amid intense competition from larger server makers Dell and HP, suffering from execution issues and Nvidia chip supply delays. Analyst Gil Luria of D.A. Davidson noted signs of market share loss. While over 70% of Super Micro’s Q4 revenue is linked to AI platforms, the company’s margins remain pressured by high AI server production costs and fierce rivalry. Bank of America analysts highlighted ongoing uncertainty over the gross margin impact this quarter.

Super Micro CEO Charles Liang expressed optimism about improved chip availability driving better growth going forward. Dell’s shares also declined 1.7% on the news.

AMD trades at a forward price-to-earnings multiple of 32.39, compared to Super Micro’s 19.69.

AMD Data Center Revenue Disappoints, Shares Drop About 4%

Advanced Micro Devices (AMD.O) reported weaker-than-expected data center revenue in its second quarter, disappointing investors betting on the company’s AI chip growth potential. Shares of the Santa Clara-based chipmaker fell roughly 4% in extended trading.

While AMD’s stock has climbed over 40% this year—outperforming the chip index’s 12% gain—its data center segment growth lagged behind rival Nvidia (NVDA.O), the dominant player in AI chips. Nvidia’s data center revenue surged 73% to $39.11 billion in its fiscal first quarter, driven by demand for its Blackwell GPUs and networking hardware.

AMD’s second-quarter data center revenue grew 14% to $3.2 billion, close to analysts’ estimate of $3.22 billion. This segment includes both server CPUs and Instinct AI chips. Portfolio manager Dan Morgan from Synovus Trust noted the “lackluster” data center results were concerning given AMD’s reliance on this segment.

CEO Lisa Su said the decline in AI chip revenue year-over-year was due to U.S. export restrictions on shipments to China and the transition to next-gen MI350 AI chips. Production of the MI350 series began ahead of schedule in June, with a planned steep production ramp in the second half of the year.

AMD also revealed that shipments of its MI308 AI chips to China remain on hold pending U.S. government export license approvals, impacting revenue. The company expects to resume shipments once licenses are granted. These export curbs are estimated to reduce AMD’s 2025 revenue by about $1.5 billion, mainly affecting Q2 and Q3.

For Q3, AMD forecast revenue of approximately $8.7 billion (±$300 million), above analyst expectations of $8.3 billion. The company projected adjusted gross margins around 54%, in line with estimates.

Adjusted earnings per share for Q2 were 48 cents on revenue of $7.69 billion, excluding stock-based compensation and other items.
