Advanced Micro Devices (NASDAQ:AMD) delivered a second-quarter earnings report that, on the surface, looked like a clear win. Revenue hit a record $11.54 billion, up 50% year over year and above the $11.28 billion analysts had expected. Adjusted earnings came in at $1.66 per share, beating the consensus estimate of $1.62. Data center revenue more than doubled, surging 107% to $6.72 billion, and now accounts for 58% of total sales.
Yet the market's reaction was anything but celebratory. After gaining 7% during regular trading, AMD shares reversed course and fell nearly 9% in after-hours trading. The culprit: management's forecast that adjusted gross margin would hold steady at 56% in the third quarter, even as revenue is projected to climb about 13% sequentially to roughly $13 billion.
The muted margin outlook suggests Wall Street is shifting its focus from how fast AMD's AI business can grow to how profitably it can grow. As one portfolio manager put it, "good" was no longer enough after a 21% run-up in the five sessions before the report. Investors wanted evidence that AMD's next growth engines were arriving faster than already optimistic assumptions implied.
Record quarter, but a hidden margin trap
AMD's adjusted gross margin improved from 55% in the first quarter to 56% in the second, but the flat guidance for the September quarter disappointed many. The concern is not that AMD's Instinct accelerators or Helios systems are unprofitable, but that early deployments may carry higher costs for networking, memory, integration, and customer roll-outs than its mature server-processor business.
AMD is also transitioning from selling individual processors to supplying complete rack-scale AI systems. This expands its revenue opportunity but makes execution, component costs, and deployment economics more critical. As one analyst noted, AMD now faces the same test as Nvidia and the hyperscalers: investors want proof that AI infrastructure investment is producing accelerating returns.
Guidance and segment performance
For the third quarter, AMD guided revenue to $13 billion, plus or minus $300 million, comfortably ahead of the $12.52 billion consensus. Client revenue rose 23% to $3.1 billion, embedded sales grew 19% to $977 million, and gaming revenue fell 31% to $779 million. The 246% jump in adjusted earnings was flattered by an unusually weak year-ago comparison, which included $800 million in inventory and related charges tied to US export restrictions on MI308 accelerators for China.
Despite the strong headline numbers, some analysts described the results as "solid but unspectacular," highlighting the gap between a technical beat and the larger upside surprise that was already priced into the stock.
Helios ramp and long-term prospects
AMD expects data center sales to accelerate in the second half and more than double by 2027. The Helios platform has begun ramping, with customers including Microsoft, Meta, OpenAI, Oracle, and Anthropic. Before the earnings release, Benchmark analyst Cody Acree said the call should be judged mainly on September guidance, gross margin, and Helios timing.
The quarter demonstrated that AMD is converting demand into revenue. The next test is whether higher volumes improve system economics and lift margins. As the AI infrastructure buildout continues, AMD's ability to scale profitably will be key to sustaining investor confidence. For broader market context, the S&P 500's next hurdle remains a focus after recent record closes, while Caterpillar's AI-driven power demand highlights the ripple effects of the AI boom across industries.
Investors will be watching AMD's execution closely in the coming quarters, as the company navigates the delicate balance between growth and profitability in the fiercely competitive AI chip market.
