Advanced Micro Devices plunged 17% after guidance disappointed investors seeking bigger AI payoffs. A financial analyst at Nexymus explores why the chipmaker’s forecast sparked its worst single-day loss since 2017.
AMD projected first-quarter revenue of $9.8 billion, plus or minus $300 million. Analysts expected $9.39 billion on average, according to Bloomberg data. However, some projections topped $10 billion based on AI momentum.
The forecast represented a sequential decline from fourth-quarter revenue. AMD reported $10.27 billion for the December period. This downturn caught observers completely off guard.
The guidance includes roughly $100 million in China AI chip sales. Export restrictions and geopolitical tensions complicate that market significantly. Trading restrictions could eliminate this revenue stream entirely.

Mixed Fourth-Quarter Results
Fourth-quarter earnings per share reached $1.53 on an adjusted basis. This beat the $1.43 consensus estimate from analysts. Revenue of $10.27 billion topped expectations of $9.67 billion.
AI chip sales to China reached $390 million during the quarter. Data center revenue climbed 39% to hit $5.38 billion. These figures initially appeared strong before guidance overshadowed them.
AMD expects an adjusted gross margin of 55% in the coming quarters. This profitability metric tracks earnings after direct production costs. The margin target signals pricing power despite competitive pressures.
CEO Su Defends Performance
CEO Lisa Su told CNBC that “AI is accelerating at a pace that I would not have imagined.” She defended the company’s results and forecast aggressively. Demand continues outstripping available compute capacity, according to her assessment.
Su emphasized internal perspective versus external perception. Someone inside the business sees momentum building continuously. The data center business strengthened significantly during the last two to three months.
“Server CPU demand remains very strong,” Su explained on the earnings call. Hyperscalers expand infrastructure to meet growing cloud and AI demands. Enterprises modernize data centers simultaneously across industries.
The NVIDIA Shadow Looms
AMD still plays catch-up with semiconductor giant NVIDIA in AI chips. This competitive position weighs heavily on investor psychology. A new, more powerful chip design arrives in the second half.
AMD claims the MI450 architecture will provide competitive advantages. Markets remain skeptical about execution against NVIDIA’s dominance. The company serves as a key AI chip provider alongside NVIDIA.
Stock surged over 100% during the past year on AI expectations. Recent guidance suggests monetization lags behind optimistic projections. Wall Street demands bigger, faster payoffs from artificial intelligence spending.
China Sales Complicate Picture
China-bound AI chip sales added $390 million in the fourth quarter. US licenses approved these transactions in early 2025. Without Chinese revenue, data center results would have missed estimates entirely.
The sales boosted revenue but pressured profit margins significantly. Older chip designs generate lower margins than cutting-edge products. Navigating trade restrictions while maintaining profitability presents ongoing challenges.
AMD commands a forward price-to-earnings multiple of 33.16 currently. This valuation demands consistent execution and growth delivery. Competitor Intel gave a disappointing forecast last month, citing supply constraints.
Customer Wins Provide Validation
AMD recently announced significant customer partnerships across the industry. OpenAI agreed to deploy 6 gigawatts of AMD Instinct graphics processing units. Initial 1-gigawatt rollout begins in the second half of 2026.
Oracle also joined the customer roster for AI chips. These partnerships validate AMD’s technology competitiveness against NVIDIA. However, partnerships don’t automatically translate into revenue growth.
CEO Su confirmed “active discussions” for additional Helios or MI450 sales. The MI450 chip ramp remains on schedule for a second-half start. These next-generation products represent future competitiveness.
Broader Semiconductor Weakness
Wednesday’s selloff occurred amid widespread technology sector weakness. NVIDIA fell approximately 3% despite no company-specific negative news. The entire semiconductor ecosystem faces renewed scrutiny about AI returns.
The iShares Semiconductor ETF declined roughly 1.6% for the session. Chipmakers collectively confront questions about demand sustainability beyond initial buildout. Markets demand proof of return on investment.
Super Micro Computer provided rare positive news in the sector. The server manufacturer jumped 12.7% after upgrading revenue forecasts. It now targets at least $40 billion in fiscal 2026 revenue.

Stock Technical Breakdown
The 17% Wednesday decline represented AMD’s worst since May 2017. Trading volume exploded to levels not seen in years. The stock finished at $200.19 after starting the session above $240.
The collapse pushed AMD’s relative strength index into deeply oversold territory. Technical analysts watch these levels for potential bounce signals. However, oversold stocks can remain oversold for extended periods.
AMD’s forward price-to-earnings multiple of 33.16 still exceeds many semiconductor peers. Super Micro Computer trades at a more modest 10.81 times forward earnings. Valuation compression could continue if AI skepticism intensifies across the sector.
The Path Forward Remains Uncertain
New Helios integrated server-scale AI systems ship later this year. These products represent AMD’s next-generation competitiveness against rivals. Active customer discussions suggest the pipeline remains healthy despite guidance concerns.
Short-term stock performance depends heavily on AI narrative evolution. If infrastructure spending continues to expand, AMD recovers ground. If skepticism about returns intensifies, further downside emerges.
The 17% single-day decline suggests investors lean heavily toward caution. CEO Su’s confidence reflects the genuine business momentum she observes. However, markets demand proof through consistent results rather than management assurances alone.
