Shares of Advanced Micro Devices fell 7.3% in pre-open trading after the chipmaker posted quarterly results that, while strong on the top line and in adjusted earnings, were overshadowed by profit margin pressures and an unexpectedly large jump in capital spending.
AMD announced record revenue of $11.54 billion for the quarter, a 50% increase year-over-year, and adjusted earnings per share of $1.66, both figures topping Wall Street expectations. The company also provided third-quarter revenue guidance of approximately $13 billion, ahead of consensus estimates near $12.5 billion.
Nonetheless, two data points drew investor scrutiny. Gross margin for the quarter was reported at 54%, below the 56% analysts had anticipated. Market commentary cited near-term cost headwinds related to the ramp of AMD's Helios AI infrastructure platform as a driver of the margin shortfall.
At the same time, the company disclosed capital expenditures of $808 million for the period, a material increase versus the roughly $314 million Wall Street had modeled. The size of the investment raised questions among investors about how much AMD will need to deploy to compete in the AI accelerator market.
The stock's downside was further amplified when SpaceX disclosed, in its own earnings release, that it would stop purchasing AMD chips and transition to Nvidia as its exclusive AI chip supplier. That development was cited as a competitive setback for AMD and contributed to the selling pressure after-hours.
Broader markets offered little cushioning for the pullback. The S&P 500 was up about 0.3% while the Nasdaq was essentially flat, indicating that AMD's pre-market weakness was driven primarily by company-specific developments rather than a broad market sell-off.
Compounding the move lower, AMD had rallied roughly 9% in the prior regular trading session ahead of the earnings announcement, a pre-earnings run-up that left the stock exposed to a "buy the rumor, sell the news" reaction once the margin and capital spending figures failed to satisfy investors.
Takeaway - Strong revenue growth and forward guidance were not sufficient to counter investor concerns about margin compression, elevated capital spending and the loss of a customer to a key competitor. Together, those elements produced a classic post-earnings reset at a time when the stock had already climbed in anticipation of the results.
Key points
- AMD delivered record quarterly revenue of $11.54 billion and adjusted EPS of $1.66, both beating expectations.
- Gross margin came in at 54%, below the 56% consensus, with near-term cost pressure linked to ramping the Helios AI infrastructure platform.
- Capital expenditures of $808 million far exceeded forecasts of roughly $314 million, raising investor concern about the scale of investment required to compete in AI accelerators.
Sectors impacted
- Semiconductors and AI hardware providers - margin and capex dynamics affect competitive positioning and capital intensity.
- Technology hardware customers and suppliers - shifts in customer relationships can alter demand flows and supplier mix.
Risks and uncertainties
- Margin risk - near-term gross margin compression tied to product ramps could pressure profitability in the short term, affecting semiconductor sector earnings expectations.
- Investment intensity - higher-than-expected capital expenditures raise uncertainty over future cash flow profiles and the amount of investment needed to remain competitive in AI acceleration.
- Customer concentration and competitive shifts - the disclosed switch by SpaceX to Nvidia introduces execution and revenue risk tied to the loss of a customer and competitive displacement.
Conclusion - AMD's quarterly report combined strong sales and guidance with metrics that unnerved investors. The margin miss, elevated capex and the customer transition to a competitor reversed prior gains and set up a reassessment of the stock at current valuation levels.
