Advanced Micro Devices shares fell about 6% on Wednesday after the chipmaker’s second-quarter results highlighted continuing pressure on its artificial-intelligence business from U.S. export restrictions to China. Revenue rose 32% year-on-year to $7.69 billion, topping analyst estimates, but adjusted earnings of $0.48 a share missed the $0.49 consensus and net profit reached $872 million. The data-center division, which houses AMD’s Instinct AI accelerators and Epyc server processors, generated $3.2 billion in revenue—up 14% from a year earlier yet down 12% sequentially—and swung to an operating loss after roughly $800 million of inventory and related charges linked to the MI308 accelerator that can no longer be shipped to China. Chief Executive Officer Lisa Su told CNBC the company excluded China sales from its outlook while license applications are reviewed by the U.S. Commerce Department. For the current quarter AMD projected revenue of about $8.7 billion, plus or minus $300 million, signalling an expected rebound ahead of large-scale AI deployments it sees beginning in the fourth quarter and extending into 2026. Su said demand for PCs remains strong and that AMD is gaining market share across client and server segments. Server-maker Super Micro Computer, viewed by investors as a barometer for AI hardware demand, slumped 17% in pre-market trading after its own data-center sales disappointed, underscoring broader concerns that the near-term payoff from AI spending is proving uneven across the semiconductor supply chain.
