AMD shares fell as much as 7.2 per cent to US$481.06 on Aug 5 after the company guided third-quarter revenue to US$13 billion, plus or minus US$300 million. The midpoint beat the US$12.5 billion consensus, but several Wall Street estimates had been modelling well north of US$13 billion, and a stock that has more than doubled in 2026 was priced for the higher number.

The whisper number was the problem

Expectations had been ratcheted up in July when chief executive Lisa Su rolled out new products the company said would outperform Nvidia and declared the AI accelerator market would reach US$1.4 trillion by 2030. The stock’s advance far outpaced the broader rally, leaving little room for a guide that merely beat consensus.

The numbers that mattered

Second-quarter sales rose 50 per cent to US$11.5 billion. Adjusted profit came in at US$1.66 a share. Analysts had estimated US$11.3 billion and US$1.62. Data centre revenue more than doubled to US$6.7 billion, edging past the US$6.6 billion average estimate. Personal computer and gaming sales rose 6 per cent to US$3.8 billion.

The 2027 promise

On the conference call Su said data centre revenue would “more than” double in 2027, adding that growth could ultimately be “well over” 100 per cent without giving exact numbers. Analysts pressed for a breakdown, a signal the outlook was not as strong as the headline implied. The company also said it is on track to exceed earlier targets of 35 per cent annual revenue growth and US$20 earnings per share.

The second-source ceiling

“AMD has already established itself as a meaningful second supplier to Nvidia in AI accelerators,” Emarketer analyst Jacob Bourne wrote. The larger question is whether it can keep up in the broader market for AI infrastructure. Capital expenditures by the biggest data centre owners are projected to exceed US$1 trillion in 2027, according to Bernstein. AMD is also closing in on Intel in central processors, which have enjoyed a renaissance supporting AI services.

The pattern

It is not uncommon for AMD to report positive results and see the stock slump. Its earnings reports have drawn negative reactions more often than not in recent years, even when estimates are topped. This report arrived late in the tech earnings season, after strong showings from customers and rivals such as Intel had already lifted the bar. Meanwhile, the AI build-out has created memory shortages that are raising prices and crimping PC supply, still AMD’s largest market by volume.
